+# Row 232 (I1): stack-release external units and bundle copies
+
+Brief: `docs/plans/2026-10-20_installer-rows.md` section I1, blob `f35e7e57daee` (commit ad6f0be7a). Gitea
+#1734, Vikunja P19 #432. Owner Darkwing, reviewer Filbert, gate owner Sage. Design input: row 195 DESIGN r6,
+`agents/darkwing/work/queue-195/DESIGN.md` at b7239bb66 (approved in duckworth-0055). Where the brief and
+r6 differ, the brief wins. sage-1561 ruled where the stack user's `stack-release.sh` runs: from its own
+clone of the release bundle, so `check_target`, the plan's commit list and status drift are unchanged and
+nothing adds `safe.directory`.
+
+## Files
+
+Base: cb5fdb064 (row 199's landing, on top of row 200's 9e1085816). Branch `darkwing/row232-r1`. The first
+build, 0af0c73c6 on `darkwing/row232`, sat on 00d4cc1f6 (row 190); row 200 landed first, so this one is
+rebased onto it (see D9 and D10).
+
+- `scripts/stack-release.sh`: `--units user|external`, the `sc` and `jctl` backend, `confirm`, `revert`,
+  `gate --since`, `rollback --to`, `--plan --expect-from`, the external gate (start floor, PM check from
+  `launches list`), `external-pm`, and the `awaiting units:` status line.
+- `scripts/stack-copy.sh`: `check --units external`, `copy --bundle FILE SHA`, `wrapper ID --create`.
+- `packages/cli/tests/stack-release-external.test.mjs` (new, 25 tests).
+- `packages/cli/tests/stack-release-fixture.mjs` (new): the helpers `stack-release.test.mjs` defined, moved
+  so both files share them. See deviation D1.
+- `packages/cli/tests/stack-release.test.mjs`: the helpers leave and one import line comes in. The 74 tests
+  have the same names and the same bodies as on the base.
+- `packages/cli/tests/stack-copy.test.mjs`: three new `row 232:` tests and a wider `node:fs` import.
+- `docs/TOOLS.md`: the stack-copy usage block and three paragraphs, the stack-release usage block, and a new
+  subsection "Root-owned units (`--units external`, row 232)".
+- `packages/cli/README.md`: one paragraph.
+- This file.
+
+The worktree's `node_modules` symlink is not part of the candidate.
+
+## User mode is unchanged
+
+Every `systemctl` call goes through `sc` and every `journalctl` call through `jctl`. Under `user` they
+are `systemctl --user "$@"` and `journalctl --user "$@"`. Under `external`, `sc` allows only `show`,
+`is-active` and `list-units`, and `jctl` returns 1, so an external run can't start, stop, install or read
+the journal even through a path the tests miss.
+
+Two tests hold the brief's "every command line and every byte of output":
+
+- `user mode: every systemctl call carries --user, and activate, rollback and check make the base's
+  calls`. A fixture repo gets the base's two scripts from `git show cb5fdb064:`. The same activate,
+  rollback and `stack-copy.sh check` run from both trees, and the recorded argv (with the fixture root and
+  port replaced by placeholders) must match line for line. Every call carries `--user`.
+- `user mode: a default activate --plan prints the base's bytes`, for four plans.
+
+The base output is produced live from the base blobs, not stored as a fixture file. See deviation D3.
+
+## r6 section 7, test by test
+
+All in `stack-release-external.test.mjs` unless named.
+
+| r6 :742-812 item | Test |
+|---|---|
+| `units-running` (N4), store, log and TAKEN left | `units-running (N4) refuses while a unit is active...`; also checks that `failed` counts as down and that the Console is checked first |
+| activate leaves the pointer, writes `AWAITING-UNITS` and a backup | `activate stages: ...`, which also checks the set's file list, `UNITS.sha256`, no `--user`, no journal call and `status` |
+| `open-activation` with zero, two, the wrong copy, one not open | `confirm and revert refuse open-activation ...` |
+| `confirm` polls: 3 s fails at `--timeout 1`, passes at `--timeout 10` | `confirm polls: bus status good after 3 s fails ...` and `confirm polls to a pass ...` |
+| `stale-start` floor with `started` at .900 | `stale-start: @1792540799 fails ...` and `stale-start is a gate code ...` |
+| `confirm` pass writes pointer, ok, removes marker; timeout writes `FAILED` and exits 1 | the two polling tests |
+| `activation-failed` when `FAILED` exists | `confirm polls: ... FAILED then refuses activation-failed` |
+| lines carry the started op, from, to, activation and backup | `sameAsStarted` in every confirm test, and sequence 7 |
+| `gate` (N2) with and without `--since` | `gate (N2, A2f): ...` and the usage test |
+| `--plan --expect-from` (N5), activate and `rollback --to` | sequence 7 |
+| A3 order: capture-failed, marker-failed, wrapper failure after migrate | `A3 order: ...` and sequence 2 |
+| refusals log no activation; `interrupted` unchanged | `open-activation` test and sequence 5 |
+| PM check: one, none, two, early, not live, other business, other instance; no journal call | `the external PM check reads launches list ...` (modes '', coder, none, twolive, early, dead, other) and `journalCalls` in every external test |
+| `external-pm` | `pm-on and activate --pm-after-harness refuse external-pm` |
+| `revert` restores TAKEN only after a migration | `revert puts the wrapper back and leaves the store ...` and sequences 2 and 8 |
+| `confirm --rollback` per cause, `unrecorded`, `rollback-failed`, mismatch | sequences 1, 2, 3, 5 and 8, and `confirm --rollback refuses rollback-mismatch, and logs rollback-failed ...` |
+| sequences 1-8 | `sequence 1:` to `sequence 8:`, each ending with the `closed` check (one started and one result line, empty `interrupted`, no marker or `FAILED`, a following `--plan` that doesn't refuse `interrupted-run`) |
+| `rollback --to` refuses not-previous; `rollback --restore` finds an external backup | sequence 7, and `confirm --rollback after a --restore swap ...` |
+| `gate` writes nothing | the `gate (N2, A2f)` test and sequence 4 compare the log, the pointer and the state tree |
+| `confirm`, `revert`, `gate`, `--to` refuse without `--units external` | `confirm, revert, gate, --to and --expect-from need --units external ...` |
+| default path: every call carries `--user`; default `--plan` bytes | the two user-mode tests above |
+
+The brief's additions, in `stack-copy.test.mjs`:
+
+- `row 232: copy --bundle copies a SHA the bundle's refactor reaches, byte-identical to copy SHA, and
+  refuses the rest`: a short SHA, a missing file, a symlink, a bundle that fails `git bundle verify`, a
+  bundle with no `refs/heads/refactor`, a SHA not in the bundle, and a SHA the bundle carries on another
+  branch that refactor doesn't reach. The bundle copy's tree matches `copy SHA`'s byte for byte, and the
+  `release:` and `bundle sha256:` lines are checked.
+- `row 232: wrapper --create writes the first wrapper only, the same bytes wrapper ID writes, and refuses
+  over any file`, a symlink included. Without `--create` a missing wrapper still refuses.
+- `row 232: check --units external reads the system units, the default reads the user units`.
+
+## Mutants
+
+`mutants.sh` in my scratch (not committed, it edits the worktree), 17 mutants: r6's re-pin list (:817-838)
+minus the three `case1-repin.sh` ones, plus the brief's two. Each one applies exact replacements after a
+checked backup, runs `bash -n`, runs its named killers, restores the file and checks its sha256. Two
+controls run first with no change: the whole external file, and stack-copy's `row 232:` tests.
+
+| Mutant | Killers |
+|---|---|
+| m01 `confirm` writes the pointer on a gate failure | `confirm polls: bus status` |
+| m02 `gate_once` in place of `gate` | `confirm polls to a pass`, `stale-start is a gate code` |
+| m03 PM check counts any instance | `external PM check` |
+| m04 PM check drops the `startedAt` bound | `external PM check` |
+| m05 `confirm` takes the newest `AWAITING-UNITS` | `open-activation` |
+| m06 `rollback --to` skips the comparison | `sequence 7:` |
+| m07 the default path drops `--user` from one call (`is-active`) | `user mode: every systemctl` |
+| m08 the timeout writes r4's interim `rollback pending` line | `confirm polls: bus status`, `sequence 1:`, `sequence 5:` |
+| m09 `AWAITING-UNITS` last, after the wrapper | `sequence 2:` |
+| m10 a refusal names the open activation | `sequence 5:`, `open-activation` |
+| m11 `stale-start` is a refusal | `stale-start is a gate code` |
+| m12 `revert` restores without `MIGRATING` | `revert puts the wrapper back` |
+| m13 `confirm` logs op `confirm` | `sequence 7:`, `confirm polls to a pass` |
+| m14 `MIGRATING` after the migration | `sequence 8:` |
+| m15 `gate` takes its floor from the log without `--since` | `gate (N2` |
+| m16 `copy --bundle` skips the reachability check | stack-copy `row 232:` |
+| m17 `wrapper --create` overwrites | stack-copy `row 232:` |
+
+## Deviations and choices
+
+D1. The shared helpers moved to a new file, `packages/cli/tests/stack-release-fixture.mjs`. The brief's
+files list names `stack-release.test.mjs` "where a shared helper moves" but not a destination. Importing
+from the other test file would run its 74 tests twice, so the helpers need a module of their own.
+
+D2. The fixture's T17 check (what a run may never remove) now exempts a rollback set's `AWAITING-UNITS` and
+`FAILED`. `confirm` removes both when it closes the activation (r6 A5 and R4). User mode writes neither, so
+user-mode runs check exactly what they did.
+
+D3. The user-mode argv and `--plan` tests read the base's scripts with `git show cb5fdb064:` rather than
+storing their output as a fixture file. A later row that changes user-mode output on purpose moves the
+`BASE` constant in the test to its own base, or the test fails. I chose this over a stored fixture because
+a stored copy can drift from the base without anyone noticing.
+
+D4. `marker-failed` is reached by making `state/stack-rollback` unwritable. r6 says "an existing `$RS`", but
+`next_activation` never picks a taken name, so no test can make the run meet an existing `$RS`. The
+exclusive `mkdir` is still what refuses.
+
+D5. The stale-start polling case turns the enter time to `@1792540800`, not r6's `@1792540805`, with the
+started line at 1792540800.900. That also checks that the floor is the whole second, so .900 doesn't push it
+to 1792540801.
+
+D6. No fake `sudo` or `case2-unit.sh`. r6's sequences ran under them because r6 had `case1-repin.sh` drive
+the steps, and that script is I3's. Here the test plays root: it stops and starts the fake system units and
+installs with the existing `bus-service.sh` and `webui-service.sh` stand-ins, between the real
+`stack-release.sh` calls, on one log.
+
+D7. The fake marker in the `open-activation` test is named `20000101T000000Z-<C1 prefix>` so it sorts
+before the real one. A marker that sorted after it would leave m05 (newest marker) alive.
+
+D8. m10 sets `ACT` inside `open_activation`, where r6's wording ("ACT set before the checks") lands in this
+code. `ACT` is set only after every check in `confirm`.
+
+D9. Row 200's `--sso` is a usage error under `--units external`, with the proof flags, `--no-proof` and
+`--no-send`. It is a Console flag, and root's Console unit carries the Console flags; the script under
+external renders no Console line and never calls `console_for_target`, so `sso_checks` doesn't run there
+either. The usage text, the TOOLS.md bullet and the external usage test name it.
+
+D10. Row 200's `config_checks` runs under `--units external` too, after `plugin_checks`, in both the
+`--plan` and run paths of `activate` and `rollback --to`. It checks the target's loader against the stack
+user's `config.json`, which the bus on a VM still reads, so a `console` key the target refuses would break
+root's bus start the same way. The cost is one more refusal (`config-console-key`) an external run can
+print; I took it over a bus that fails after root's start. The rebase changed no user-mode line: the
+conflicts were the `SSO=0` globals line, the `plan` body (row 200's `SSO_PLAN` line sits in the user
+branch) and the two `--plan` lines that gained `config_checks`. In the tests, row 200's fixture lines
+(the loaders, `sso-config.mjs` and the `--sso` cli.mjs line for C1 and C) moved into
+`stack-release-fixture.mjs` with the rest of the copy setup, and the `ALGS` import stays in
+`stack-release.test.mjs`, which T57 uses.
+
+## duckworth-0055's notes on r6 (brief line 169)
+
+Duckworth's r6 approval (REVIEW-r5.md at 23f5520b5) carried two notes.
+
+- N1, A2's stop timeout under `gate --since`. A unit that never stopped keeps its old `ActiveEnterTimestamp`,
+  so `gate --since` fails it with `stale-start`, and the run ends at exit 2 with root stopping the units.
+  That is intended: a unit that won't stop is a fair reason to stop. In I1 this is the gate code and its
+  polling (`stale-start: @1792540799 fails ...`, `gate (N2, A2f)`, m11). The run sheet's A2f line and the
+  re-pin test that points "exits 1 with OLD's gate passing" at an A3 exit 3 belong to I3, which owns
+  `scripts/stack-upgrade.sh` and `docs/guides/host-run-sheet.md`. I'll name both in the I3 build.
+- N2, the claude path under `/opt/mosaic-stack` (gosalyn-0058, sage-1522). I1 doesn't touch it. Under
+  `--units external` the script checks no claude pin of its own (`no-claude-pin` applies only to user
+  mode), because root's unit carries it. The `--claude` value, the managed-settings reasoning, F6 and the
+  run sheet's claude step go to I2 and I3.
+
+## Run environment
+
+Worktree `/mnt/storage/scratch/darkwing-r232`, `TMPDIR=/mnt/storage/scratch/tmp/r232`, node from PATH.
+One external file run takes about 94 s.
+
+## Results
+
+Singles on the rebased candidate, before the gate:
+
+| File | Tests | Pass | Fail |
+|---|---|---|---|
+| `packages/cli/tests/stack-release-external.test.mjs` | 25 | 25 | 0 |
+| `packages/cli/tests/stack-copy.test.mjs` | 16 | 16 | 0 |
+| `packages/cli/tests/stack-release.test.mjs` (row 200's T57 included) | 192 | 192 | 0 |
+| `packages/cli/tests/stack-instances.test.mjs` | 23 | 23 | 0 |
+| `packages/webui/tests/pinned-copy.test.mjs` | 10 | 10 | 0 |
+| `packages/cli/tests/channel-recovery.test.mjs` (imports `channel-fixture.mjs`, which names the scripts) | 1 | 1 | 0 |
+| `packages/cli/tests/host.test.mjs` (reads `packages/cli/README.md`) | 42 | 42 | 0 |
+
+These are every test file that reads `stack-release.sh` or `stack-copy.sh` (a grep of `packages/*/tests` and
+`scripts/`). None of them pins a sha256 of a changed file. `packages/cli/tests/host.test.mjs` reads
+`packages/cli/README.md` for a unit file name; this row only adds a paragraph there. The grep and the runs
+were repeated on the rebased tree on 2026-10-21; the reader set is the same. A dry run of `mutants.sh`
+matches each of the 17 replacements once on the rebased scripts.
+
+### Gate, 2026-10-21, Sage's slot (sage-1618)
+
+Candidate a0ffabc3f on `darkwing/row232-r1`, run by `~/darkwing-scratch/r232/gate.sh`: the cli suite, then
+every `scripts/test-*.sh`, one after another, stopping at the first failure. busy.sh passed at 01:07:49Z
+after Launchpad's single `stack-release.test.mjs` run ended. The gate stopped at the first one, so the
+chain waited for that PID to exit and checked again. The EXIT trap removed the compose network; no
+container was left.
+
+| Step | Time (UTC) | Result |
+|---|---|---|
+| `packages/cli`, `node --test tests/*.test.mjs` | 01:07:50 to 01:17:53 | 561 pass, 0 fail, 0 skipped |
+| `scripts/test-auth.sh` | 01:17:53 to 01:17:54 | 15 passed, 0 failed |

+| `scripts/test-task.sh` | 01:19:51 to 01:20:44 | 98 passed, 0 failed |
+
+### Mutants, 2026-10-21, same slot
+
+`~/darkwing-scratch/r232/mutants.sh`, right after the gate. Both controls (the external file whole, and
+stack-copy's `^row 232: ` tests) exited 0 on the unmutated tree. Each mutant was applied after a checked
+backup and a syntax check, ran its killers from the table above, and was put back with its sha256
+checked. The script stops on any restore mismatch, and it ran to its end.
+
+| Mutant | Killer exit | Result |
+|---|---|---|
+| m01 pointer on gate failure | 1 | killed |
+| m02 gate once | 1 | killed |
+| m03 PM from any instance | 1 | killed |
+| m04 no startedAt check | 1 | killed |
+| m05 newest marker | 1 | killed |
+| m06 --to not compared | 1 | killed |
+| m07 one call without --user | 1 | killed |
+| m08 interim pending line | 1 | killed |

+| m15 gate floor from the log | 1 | killed |
+| m16 bundle reachability unchecked | 1 | killed |
+| m17 --create overwrites | 1 | killed |
+
+17 of 17 killed, 01:22:16 to 01:24:32Z. I read the logs for m01 and m09, two of the quick kills: each failed on
+its named test's assertion (m09 on `AWAITING-UNITS` in sequence 2), not on a load error.
+
+## Round 2: rebase onto 8fede5fc6 (sage-1673)
+
+Rebase only. Before the landing gate, a check of BASE..HEAD on the manifest paths found that row 230
+(c8bc5cf4c) had changed one of them after the round 1 base, cb5fdb064. Sage ruled a re-round with a
+scoped review, the same shape as row 210 round 3.
+
+Branch `darkwing/row232-r2`: the two round 1 commits, a0ffabc3f and 84f1a91e6, cherry-picked onto

+- `git merge-tree --write-tree origin/refactor darkwing/row232-r1` (refactor at 8fede5fc6) gives tree
+  837bde79236c with no conflict. The cherry-picked tip before this section has the same tree.
+- `packages/cli/README.md` is a clean 3-way merge. Row 230's hunk is at lines 710-717 (the session credential
+  paragraph); this row's is a new paragraph at 773. With `git patch-id --stable`, the README diff from r1 to
+  r2 is 02b679e2, the same as row 230's README diff `cb5fdb064..8fede5fc6`. This row's README diff is
+  c395ecd2 on both bases (`cb5fdb064..r1` and `8fede5fc6..r2`).

+  `packages/cli/tests/stack-release.test.mjs`, `scripts/stack-copy.sh`, `scripts/stack-release.sh`.
+  This file also matched until this section was appended. Its other lines are unchanged.
+- The one test that reads the README, `host.test.mjs:855`, looks for the unit's `EnvironmentFile=` line.
+  That line is unchanged context in row 230's hunk.
+- No row 230 test reads `stack-release.sh` or `stack-copy.sh`, and no test of this row reads a row 230 file.

+Nothing was run for this round. The landing gate runs on the r2 tip on Sage's slot.

+
+Brief: `docs/plans/2026-10-20_installer-rows.md` section I3, blob `e61291bcf1c6` (commit a0e3d7cfd), re-pinned
+by Sage (sage-1685, rev 2631) from `f35e7e57daee` (ad6f0be7a). The later blob only appends I4; the I3 text
+is the same. Gitea #1735, Vikunja P19
+#432. Owner Darkwing, reviewer Filbert, gate owner Sage. Design input: row 195 DESIGN r6,
+`agents/darkwing/work/queue-195/DESIGN.md` at b7239bb66, sections 2, 4 and 7. Where the brief and r6
+differ, the brief wins. Sage's rulings during the build: sage-1650 and sage-1652 (`--backup last`, the
+`--no-rehearsal` mapping, `--rehearse-port`, hostcheck), and sage-1653 (`from_log newest`, the two external
+plan refusals, the `BACKUP_STORE` line).

+## Files
+
+Base: e65a3ab4d, row 232's landing, on `darkwing/row233-r1`. The build started on ea1e85c7b
+(`darkwing/row233`, row 232's candidate e6ca230d2 and its BUILD.md) before row 232 landed. The three row 232
+files this row changes are identical on the two bases, so the uncommitted diff moved across unchanged.

+- `scripts/stack-upgrade.sh` (new): `upgrade` and `rollback`, root's side of r6 A1-A5, A2f and R1-R4.

+- `docs/guides/host-run-sheet.md` (new).

+  row 232 lines below.
+- Row 232 files, changed on Sage's rulings (the brief's files list doesn't name them):
+  - `scripts/stack-release.sh`:
+    - `rehearse --backup last` takes the newest backup the log records (`from_log newest`) and prints
+      `PASS backup-last`. With none it fails `no-backup`, exits 3 and makes no rehearsal directory.
+      A newest backup that isn't an activation id aborts `backup-unreadable`, exit 1.
+    - The rehearsal prints `BACKUP_STORE <activation id> schema <version>` before its migration step.
+    - `--plan` under `--units external` refuses `open-activation` when any rollback set holds
+      `AWAITING-UNITS`, and `migrate-required` for a migrating target without `--migrate`. Root reads
+      only the plan's exit, so these two have to be refusals there. User mode prints the same bytes.
+  - `packages/cli/tests/stack-release.test.mjs`: three new `row 233:` tests for `--backup last`.
+  - `docs/TOOLS.md`: `--backup ACTIVATION|PATH|last` in the rehearse usage, a paragraph on `last`, and a
+    paragraph on the two external plan refusals.

+
+## The brief, item by item
+
+| Brief item | Where |
+|---|---|
+| Root runs from a root-owned checkout, never a copy | `head-mismatch` (A1); TOOLS.md; run sheet section 6 |
+| I2's render with `/etc/mosaic-stack/<instance>.args`, `--copy` the one changed value | `read_args`, `args_with`; the args test |
+| The args file changes only after a confirmed run | `prepare_args` before A2, `mv` after A5; sequences 1 and 7, m6 |
+| `copy --bundle` as the stack's user before A1 | the `fetch`, `ff`, `copy` steps; sequence 1's sudo keys |
+| A rehearsal before A2, a failed one refuses with nothing stopped | `rehearse`; three rehearsal tests, m4 |
+| The root lock, held to the end, rollback included | `flock -n 9`; the lock test and sequence 3's probe, m1, m2 |
+| A1 refuses `open-activation` | stack-release.sh's external plan; the AWAITING-UNITS test, m3 |
+| `migrate-required` without `--migrate` | stack-release.sh's external plan; its test, m5 |
+| The step log, 0640, one line per step | `logl`, `step`; every test checks lines against `STEP` |
+| Exit codes 0-3 | `finish`, `refuse`; exit 4 is usage |
+| duckworth-0055's notes | the next section |
+| Root parses no stack user output beyond exits | the step log test; the one exception is sage-1653's `BACKUP_STORE` |
+| The host run sheet | `docs/guides/host-run-sheet.md` |
+
+## duckworth-0055's notes on r6 (brief line 169)
+
+- N1, A2's stop timeout under `gate --since`. Row 232's BUILD.md left two pieces to I3. The run sheet's
+  A2f line is in section 6 ("When a run doesn't exit 0", exit 2). The test is `N1: a bus that outlives
+  A2's timeout keeps its old start`: a bus that ignores `stop` keeps its old `ActiveEnterTimestamp`,
+  `wait-down` logs `rc=1 ... state: active`, A2f restarts and gates, the gate fails `stale-start`, and the
+  driver stops both units and exits 2. Sequence 4 is the other half: an A3 exit 3 goes to A2f and exits
+  1 with the old copy's gate passing.
+- N2, the claude path under `/opt/mosaic-stack`. Run sheet section 3 installs it there as root with
+  managed settings. The args file's `--claude` carries it, and `case2-unit.sh` already refuses a binary
+  that isn't root's or sits under the home. The driver passes the args file through and adds no claude
+  check of its own. F6 is I2's.
+
+## Sage's rulings during the build
+
+- sage-1650 and sage-1652. Root always runs the rehearsal and maps its exit:
+  - 0 goes on, or refuses `rehearsal-required` with `--no-rehearsal`.
+  - 3 refuses `no-backup`, or with `--no-rehearsal` logs `rehearsal-skipped` and goes on.
+  - Anything else refuses `rehearsal-failed`.
+
+  `--rehearse-port N`, default 7339. Hostcheck: a missing file or a nonzero `--check` refuses
+  `profile-drift`.
+- sage-1653. `from_log newest`, and the external plan refusals `open-activation` and `migrate-required`.
+  Residual: the `BACKUP_STORE` id and schema land in root's step log, but nothing ties that backup to the
+  one the activation's own backup step takes later. A stopped backup before the upgrade would close that
+  gap; it's a later row, not this one.
+
+## Tests
+
+`stack-upgrade.test.mjs` runs the driver as the test's user against a scratch root, with the test seams
+`STACK_UPGRADE_*`. The stand-ins are a fake `sudo` (logs its argv, checks the driver's form, then runs the
+real command as the test's user, r6's B1 pattern), a fake `case2-unit.sh` render that installs and starts
+the fixture units, a fake `systemctl` for root's system units, and a shell `hostcheck.sh`. The stack's
+user's steps run the real `stack-release.sh` and `stack-copy.sh` from a clone made from a real bundle. The
+units, copies and store are `stack-release-fixture.mjs`'s.
+
+| Test | Covers |
+|---|---|
+| sequence 1 | confirm fails healthz, rollback with `--cause A5`, exit 1; every sudo call in the driver's form |
+| sequence 2 | `activate --migrate` fails at the wrapper, store restored, `--cause A3`, exit 1 |
+| sequence 3 | render fails, `--cause A4`; a probe run during `render-old` refuses `upgrade-running` |
+| sequence 4 | stage exits 3, A2f restarts and gates the old units, exit 1 |
+| N1 | a unit that won't stop: A2f's gate fails `stale-start`, exit 2, units stopped |
+| sequence 5 | confirm of the wrong copy refused, `--cause A5`, exit 1 |
+| sequence 6 | revert fails, exit 2; the next run refuses `interrupted-run` at its plan |
+| sequence 7 | two upgrades and a `rollback --to` with `--restore`; the args file after each confirm; `to-not-previous` |
+| sequence 8 | a migration that writes and fails, store back byte for byte, exit 1 |
+| lock | a second run while the lock is held: one log line, no call |
+| open-activation | any `AWAITING-UNITS` refuses at A1, nothing stopped |
+| migrate-required | refused without `--migrate`, no rehearsal, nothing stopped |
+| rehearsal-failed | the rehearsal's argv, exit 3, nothing stopped |
+| `BACKUP_STORE` | the line after a match; four malformed lines log `BACKUP_STORE none` |
+| no-backup | the real rehearsal with no backup refuses; `--no-rehearsal` logs the skip and goes on |
+| backup-last | the real rehearsal names the newest backup; `--no-rehearsal` with one refuses `rehearsal-required` |
+| args file | group write, other write, two `--copy`, an unknown flag, a symlink, `args-differ` |
+| hostcheck | nonzero `--check` and a missing file refuse `profile-drift` before the plan |
+| head-mismatch | checkout not at `--sha`; a commit the clone can't fast-forward to refuses `fetch-failed` |
+| usage | twelve bad argvs exit 4 with no log and no lock |
+
+The step log check (`STEP`) runs in every test that reads the log: each line must be a step line or the
+result line, and none may hold the stack user's output (`stack-release:`, `PASS `, `FAIL `, `REHEARSAL`,
+the fake rehearsal's text).
+
+## Mutants
+
+`~/darkwing-scratch/r233/mutants.sh`, not committed because it edits the worktree. It has the brief's six
+mutants and two for sage-1650's mapping. The method is row 232's: a checked backup, exact replacements, a
+syntax check, the named killers, then the file put back with its sha256 checked. One control runs first:
+the whole `stack-upgrade.test.mjs` with no change. `DRY=1` matched each replacement once on the candidate
+(2026-10-21).
+
+| Mutant | File | Killers |
+|---|---|---|
+| m1 drop the flock | stack-upgrade.sh | `a second run while the lock is held`, `sequence 3:` |
+| m2 release the lock when the rollback starts | stack-upgrade.sh | `sequence 3:` |
+| m3 skip A1's open-activation check | stack-release.sh | `A1 refuses open-activation` |
+| m4 skip the rehearsal | stack-upgrade.sh | `the rehearsal runs after the plan`, `sequence 1:` |
+| m5 accept a migrating target without `--migrate` | stack-release.sh | `migrate-required` |
+| m6 write the args file before confirm | stack-upgrade.sh | `sequence 7:`, `sequence 1:` |
+| m7 `--no-rehearsal` accepted with a backup | stack-upgrade.sh | `refuses rehearsal-required` |
+| m8 drop the `rehearsal-skipped` line | stack-upgrade.sh | `a real rehearsal with no backup` |
+
+## Deviations
+
+D1. The brief has A1 refuse `open-activation` for an open `AWAITING-UNITS` or a non-empty `interrupted`
+set. The interrupted case refuses with row 232's existing code, `interrupted-run`; only `AWAITING-UNITS`
+gives `open-activation`. Both reach root as `plan-refused`, exit 3 (sequence 6, the open-activation test).
+
+D2. Root copies one line of the stack user's output into its log, `BACKUP_STORE`, on sage-1653. It
+matches a fixed pattern first, takes the last match, logs `BACKUP_STORE none` otherwise, and decides
+nothing on it.
+
+D3. The stack user's steps carry no `--instance`. The driver takes `--instance dev` only, row 190's default
+instance, which the stack user's commands select with no flag. A named instance's units are a later row.
+
+D4. Most tests fake the rehearsal in the fake `sudo`: the fixture's stub copies can't pass a real one. Two
+tests run the real rehearsal (`faults/real-rehearse`): no-backup and backup-last. `stack-release.test.mjs`
+covers `--backup last` itself.
+
+D5. Any nonzero `--plan` exit refuses `plan-refused`, exit 3, whatever the code. The stack user's output
+above it names the refusal; root doesn't parse it.
+
+D6. `rollback --restore ACT` is accepted without `--events`, as `stack-release.sh rollback` accepts it.
+The brief's usage pairs them. `--events` without `--restore` is a usage error.
+
+D7. The refusal of any `STACK_UPGRADE_*` seam when run as root has no test, because the tests don't run
+as root. It is three lines at the top of the script.
+
+D8. The fake `sudo` keeps the test's environment, where real `sudo` resets it. The driver passes
+everything the stack user needs through `env PATH=...` and `-H`, and the fake checks that form.
+
+D9. Exit 3 means nothing stopped, not nothing changed. A refusal after `fetch` leaves the stack user's
+clone fast-forwarded and the new copy made. Both are the user's own state, and the next run reuses them.
+TOOLS.md and the run sheet say so.
+
+D10. The brief's usage has neither `--no-rehearsal` nor `--rehearse-port`. Both come from sage-1650 and
+sage-1652.
+
+## Decisions
+
+- `rollback` has no HEAD check. Its target is an older copy than root's checkout, which already exists.
+  It fetches, copies and rehearses nothing (sequence 7).
+- The new args file is written next to the old one (`.dev.args.XXXXXX`, same mode) before A2, so a full
+  `/etc` refuses before anything stops. It moves into place after A5. A2f and the rollback remove it; a failed move keeps it and names it.
+- Every stack user step gets `--copies` explicitly, so the copies directory comes from the args file's
+  `--home`, never from the user's environment.
+- The stack's user does the fetch, the fast-forward and the copy, so root never runs git on a tree that
+  user can write.
+- A4 is the render, and `case2-unit.sh` starts the bus, then the Console. The forward path has no
+  `systemctl start` of its own; only A2f does.
+
+## Run environment
+
+Worktree `/mnt/storage/scratch/darkwing-r233`, `TMPDIR=/mnt/storage/scratch/tmp/r233`, node from PATH. One
+whole `stack-upgrade.test.mjs` run takes about 56 s.
+
+## Results
+
+### Singles, run 1, 2026-10-21, Sage's slot (sage-1689)
+
+`~/darkwing-scratch/r233/singles.sh` on `darkwing/row233-r1` (base e65a3ab4d, uncommitted tree), 03:48:20Z
+to 03:59:00Z. These are the test files that read a changed script. `stack-instances.test.mjs` reads
+`stack-release.sh`, so it joined the three named in the plan.
+
+| File | Result |
+|---|---|
+| `stack-upgrade.test.mjs` | 20 pass, 0 fail |
+| `stack-release.test.mjs` | 194 pass, 1 fail |
+| `stack-release-external.test.mjs` | 25 pass, 0 fail |
+| `stack-instances.test.mjs` | 23 pass, 0 fail |
+
+The failure was my test, not the script. "row 233: --backup last takes the newest backup..." compares
+`untouched(e)` before and after the run, and `untouched` includes `existsSync(e.log)`. The test took its
+before snapshot ahead of `rlog()`, which writes the log, so that flag went from false to true. Every hash in
+the snapshot matched. The fix takes the snapshot after `rlog()`. No other row 233 test calls `untouched`.
+
+### Singles, run 2
+
+`~/darkwing-scratch/r233/rerun.sh` on aacfa2d7a, Sage's slot (sage-1695), 04:13:05Z to 04:21:28Z:
+`stack-release.test.mjs` whole, 195 pass, 0 fail, 0 skipped. The fixed test passed. The other three files
+did not change after run 1. The gate and the mutants run next, in Sage's slot.
+
+### Gate and mutants, 2026-10-21, Sage's slot (sage-1704)
+
+`~/darkwing-scratch/r233/gate.sh` then `mutants.sh`, chained behind `busy.sh`, on d99166ade (code
+aacfa2d7a; d99166ade changes only this file). Counts are an awk sum over `gate-r1.out`.
+
+| Part | Time (UTC) | Result |
+|---|---|---|
+| cli suite (`node --test tests/*.test.mjs`) | 04:29:01-04:37:27 | 616 pass, 0 fail, 0 skipped |
+| the 10 `scripts/test-*.sh` | 04:37:27-04:39:38 | selftests 429 passed, 0 failed; `test-queue`'s node part 156 pass, 0 fail |
+| gate total | | 1201 pass, 0 fail, 11 suites, `GATE_PASSED` |
+| c0 control | 04:39:38-04:40:35 | exit 0 |
+| m1-m8 | 04:40:35-04:41:25 | 8 of 8 killed, every one exit 1 |
+
+Every restore passed its sha256 check, and `git diff` was clean at d99166ade afterwards. The EXIT trap
+removed the `darkwing-r233_default` network.
+
+N1, found in the process sweep after the run: a `sleep 60` was left with its cwd in `packages/cli`.
+`stack-upgrade.test.mjs:312` spawns `flock LOCK sleep 60`, and its `t.after` SIGKILLs only the flock, so
+flock's child outlives the test by up to 60 s. It exited on its own. Row 232's T20
+(`stack-release.test.mjs:370`) spawns its holder `detached` and kills the group with `process.kill(-pid)`.
+The fix is the same two lines. That test is one of m1's killers.
+
+Sage ruled it a fix now (sage-1707), and 08db6ac3f makes it, test only. After the gate's d99166ade
+the only change outside this file is that test:
+
+```
+$ git diff --stat d99166ade 08db6ac3f
+ packages/cli/tests/stack-upgrade.test.mjs | 4 ++--
+ 1 file changed, 2 insertions(+), 2 deletions(-)
+```
+
+The gate stands on Sage's ruling. The rerun is the whole `stack-upgrade.test.mjs` singly plus m1, in
+Sage's slot, with a sweep for a leftover `sleep` afterwards.

+
+Brief line 257 said I3's `stack-upgrade.sh` doesn't change. Sage's ruling sage-1727 widened the row to it for
+N1 alone. Its default `STACK_UPGRADE_HOSTCHECK=/usr/local/lib/mosaic-stack/hostcheck.sh` is where the run
+sheet installs this script.
+
+## Carried from I3
+
+Filbert's row 233 approve (Gitea 29922) left five notes. Sage ruled N1, N4 and N5 into this row and N2 and N3
+to DEFERRED.md (sage-1727).
+
+| Note | Change |
+|---|---|
+| N1: `stack-upgrade.sh` exits 1 `args-failed` when the args move after A5 fails, but exit 1 means the old copy runs | The move's failure exits 5 `args-failed`. The header, TOOLS.md's step 5 and exit line, and run sheet section 6's exit list name exit 5 and what root does: move the new file the result line names into place. Test `row 240: I3 N1: a failed args move after A5 exits 5 ...` makes `/etc/mosaic-stack` read-only at confirm and checks exit 5, the step names, `args rc=1`, the result line, both units on the new copy, the old args file's bytes and the new file beside it. The step log regex takes `exit=5`. Mutant M8. |
+| N4: section 3's `npm install` has no npm on root's PATH, and the `--claude` path is unnamed while `node_modules/.bin/claude` is a symlink `case2-unit.sh:140` refuses | The install line runs with section 2's pinned node first on PATH (the postinstall runs `node` too). The `--claude` path is `node_modules/@anthropic-ai/claude-code/bin/claude.exe`, and a `--version` line catches the postinstall's 500-byte stub. |
+| N5: sections 8 and 10 lack precheck lines | Each gets "Precheck line: none" and its missing line. |
+
+Exit 5 is new rather than 2 because 2 means both units are stopped, and here both run. Exit 4 stays usage.
+
+The `claude.exe` path comes from the 2.1.304 package itself: `npm view` gives `bin.claude` as `bin/claude.exe`,
+and its `install.cjs` hardlinks the platform binary over that placeholder, or copies it across devices, then
+sets 0755. I downloaded the tarball into `/mnt/storage/scratch/tmp/r240/cc304` and read it; nothing ran. The
+run sheet says a newer pin needs the same check.

+## Tests
+
+Fakes on PATH, each logging its argv to `$HC/calls.log`: `aa-status`, `dpkg`, `dpkg-statoverride`,
+`apparmor_parser`, `systemd-run`, `stat`, `chown`, `chmod`, `apt-get`, `dpkg-deb`. `host(t)` builds a scratch
+root (`/etc`, `/proc/sys`, `/usr/bin/bwrap`, `/var/log`) and a lib dir with a copy of the script and fixture
+pins that hold the fixture profile's sha256. Every run passes `--root`.
+
+r6's case groups (:843-856) against the tests:
+
+| r6 case | Tests |
+|---|---|
+| `--check` exits 0 with all seven, 1 with each failing alone, its line naming it | `check: exits 0 ...`, `check: exits 1 with each item failing alone ...`, plus one test per item for the item's edge cases |
+| item 3: a second file naming `bwrap` as a word, `/{usr/,}bin/bwrap` included; passes with the profile alone | `check: item 3 ...` |
+| item 4: `unpriv_bwrap (enforce)` or a trailing space fails; the argv carries `-p NoNewPrivileges=yes` and the 2a' properties | `check: item 4 ...` checks the whole argv |
+| item 7: the floor at 732 fails | `check: item 6 ...; item 7 ...` (733 passes as the control) |
+| `--enforce` exits 0 on a pass and every failure; unload, close, `DRIFT`, one log line; `DRIFT` present with every item passing still closes | `enforce: a pass ...`, `enforce: each failure ...`, `enforce: with DRIFT present ...` |
+| `--enforce` never calls `dpkg-statoverride` with `--update`, `--add` or `--remove` | `enforce: no unload ...; never writes the statoverride` (every call is `--list /usr/bin/bwrap`) |
+| a bubblewrap version other than the pin is a line, not a failure | `check: a bubblewrap version other than the install pin ...` |
+| `--upstream` against a differing deb prints the difference, exits 0 | `upstream: ...` (also: a match, a deb with no profile, a failed download) |
+| the unit: `Type=oneshot`, `After=apparmor.service`, `[email protected]`, runs `--enforce` | `boot unit: ...` |
+
+The last test also checks that the repo script reads `scripts/case1-pins.sh` beside it, that bad usage exits
+2, and that a non-root run without `--root` refuses.
+
+Singles are the two files that run a changed script: `case1-hostcheck.test.mjs` and `stack-upgrade.test.mjs`.
+Sage asked (sage-1759) whether `stack-release.test.mjs` or `stack-release-external.test.mjs`, which share
+`stack-release-fixture.mjs`, run `stack-upgrade.sh` or `case1-pins.sh`. They don't. `grep -cF` for
+`stack-upgrade`, `case1-pins`, `case1-hostcheck` and `hostcheck` gives 0 in all three files; the control
+`stack-release.sh` gives 2 in the fixture and 8 in `stack-release.test.mjs`. `scripts/stack-release.sh` names
+`stack-upgrade.sh` once, in a comment (:2061). The gate's cli suite runs both files anyway.
+
+## Mutants
+
+r6's seven (:858-860) and one for I3 N1, scripted in `~/darkwing-scratch/r240/mutants.sh` with r233's method: a checked backup,
+an exact replacement that must match once, `bash -n`, the named killer by `--test-name-pattern`, the restore
+and a sha256 check. A dry run matched all eight once each. Results below.
+
+| Mutant | Change | Killer |
+|---|---|---|
+| M1 | `--enforce` exits 1 after the stop | `enforce: each failure exits 0 ...` |
+| M2 | `[ ! -e "$DRIFT" ] \|\| had=1` becomes `true \|\| had=1` | `enforce: with DRIFT present ...` |
+| M3 | item 1's `dpkg -S` becomes `owner=""; rc=1` | `check: item 1 fails when a package owns ...` |
+| M4 | item 3's `grep -rlw bwrap` becomes `grep -rlF /usr/bin/bwrap` | `check: item 3 ...` |
+| M5 | item 4's `[ "$label" = "$LABEL" ]` becomes a substring match | `check: item 4 ...` |
+| M6 | item 4 drops `-p NoNewPrivileges=yes` | `check: item 4 ...` (argv) |
+| M7 | item 7's `-gt` becomes `-ge` | `check: item 6 ...; item 7 fails with the floor at 732 ...` |
+| M8 | `stack-upgrade.sh`'s `finish 5 args-failed` becomes `finish 1 args-failed` (I3 N1) | `row 240: I3 N1: a failed args move ...` |
+
+## Deviations
+
+- Repo name `scripts/case1-hostcheck.sh` (r6), installed as `/usr/local/lib/mosaic-stack/hostcheck.sh`, the
+  name in brief line 239 and I3's `stack-upgrade.sh` default. r6's apt hook line says `case1-hostcheck.sh`;
+  the run sheet's hook uses the installed name.
+- `stat` is a fake too. r6 lists seven fakes; a test can't make a root-owned file, so item 5's `stat` reads a
+  fixture.
+- Item 7 with no Console unit installed reads the port as 1023 and says so ("1023, because no Console unit
+  is installed"). Until I2 installs the unit the floor must be above 1023. A unit with no `--port` fails.
+- Item 4 runs under `timeout 60`. A hung `systemd-run` would otherwise hang the apt hook and the boot unit.
+
+## Decisions
+
+- Fail closed where r6 is silent:
+  - pins with no 64-hex sha fail item 1;
+  - `dpkg -S` exit 1 (no owner) passes, exit 0 fails with the owner, any other exit fails with the code;
+  - a failed `aa-status` fails item 2 and counts as loaded, so `--enforce` tries the unload.
+- `--root DIR` is the test seam (r6 :840). Root refuses it; a non-root user needs it. Both exit 2. Root runs
+  with `PATH=/usr/sbin:/usr/bin:/sbin:/bin`.
+- `DRIFT` is append-only (`<stamp> <failed line>`), and `--enforce` never removes it. The log line is written
+  only when the stop runs: `<stamp> enforce stop items=<ids or none> drift-before=<0|1> unload=<rc=N|no-file|skipped> chown=N chmod=N`.
+- `--upstream` exits 1 when the download or the unpack fails, since it then compared nothing. A deb without
+  the profile file is a difference (exit 0), per r6 :302-303.
+- The bubblewrap note reads the version from `dpkg -s bubblewrap`.
+- The run sheet's recovery steps (`chown root:mosaic`, `chmod 0750`, `apparmor_parser -r`, then `--check`
+  before root removes `DRIFT`) are mine. r6 says only that root removes `DRIFT` in a reviewed step.
+
+## Run environment
+
+Worktree `/mnt/storage/scratch/darkwing-r240b`, branch `darkwing/row240-r3` on c771a36f4, with `node_modules`
+linked to the canonical checkout's. Node v26.8.1, kernel 7.2.2-1-cachyos, 16 CPUs, TMPDIR
+`/mnt/storage/scratch/tmp/r240`, compose project `darkwing-r240b`. Sage's slot (sage-1773, 06:16Z). Each run is
+one chain behind `busy.sh`, launched from `/`: `~/darkwing-scratch/r240/run-all.sh` checks the HEAD pin and a
+clean tree, runs the singles, then the mutants (8 killed, none surviving, the tree clean after), then the gate
+(the cli suite and every `scripts/test-*.sh`), each stopping the chain on failure, then sweeps `/proc` cwd links
+for anything left in the r240 trees.
+
+## Results
+
+Run r1, 06:17:10Z on 47ec9fe2f, failed at the singles. `case1-hostcheck.test.mjs` passed 16/0/0, and
+`stack-upgrade.test.mjs` went 20 pass, 1 fail. The failure was the N1 test's own `t.after` hook, which ran
+`chmodSync(e.etc, 0o755)` after the fixture's cleanup had already removed the scratch root, so it threw ENOENT.
+Every assertion in the test body had passed, exit 5 included. The fixture's cleanup runs `chmod -R u+w` on the
+root before `rmSync`, so the 0555 dir never needed the hook. b45852daa drops it and changes nothing else. The
+mutants and the gate didn't run. The sweep found nothing left. Sage counted r1 as this slot's one failure
+(sage-1788).
+
+Run r2, 06:20:41Z to 06:33:28Z on b45852daa, passed. The counts come from awk over the .out files

+# Row 234 (#436a row a, Gitea #1740): host enrollment, store records and bus schema 3i to 3j
+
+Gizmoduck, 2026-10-21. Reviewer Duckworth, gate owner Sage. Lands by 10-25, before the .53 and .54 installs
+(mos-1134).
+
+- Brief: `docs/plans/2026-10-20_host-credentials.md`, section "Machine grant row a: enrollment, store records
+  and migration 3i-3j", blob 64451be5 (queue rev 2617).
+- Design: `agents/gizmoduck/work/machine-grant/DESIGN.md` r6, f9039682e on `gizmoduck/machine-grant-design`,
+  approved by Duckworth (duckworth-0064, REVIEW-r6.md at 8ea792256). Not reopened here. Cites "r6:" are lines

+  96510b83778e79a71b33d0d5f6fd0c806dfe74f6de315ff4a9f1fbe5620f6c69, approved by Duckworth (duckworth-0067).
+- Base: origin/refactor 8fede5fc6, with rows 199 (cb5fdb064) and 210 (f5753c0e8) landed. Branch
+  `gizmoduck/row234`. Code cites are `path:line` at 8fede5fc6 unless they say otherwise.
+
+## Names: r6 against section 7
+
+r6's `grant.*` and `host.enroll.*` names are `body.action` values on `action.allowed` events, not event
+kinds. The `events` kind CHECK isn't rebuilt. Four r6 names move under `grant.`:
+
+| r6 | This row |
+|---|---|
+| `host.enroll.step` | `grant.host.enroll.step` |
+| `host.enrolled` | `grant.host.enrolled` |
+| `host.checked` | `grant.host.checked` |
+| `host.removed` | `grant.host.removed` |
+
+Only the consume record carries `decision`: `{operation: 'grant.host-enroll', decision}`. Every other
+guarded body names the decision `grantDecision`, so r6's `decision` field in step, enrolled and failed bodies
+is `grantDecision` here. The actor of every guarded event is `actor_role` NULL with `actor_run` 'grant',
+and `body.by` names the caller the broker checked.
+
+## Split (r6 section 12 Q-S4)
+
+Row a builds:
+
+1. **Schema 3i to 3j.** `migrations/3i-3j.sql` adds `hosts` and `host_grants` (r6 S1, primary keys
+   (business, host) and (business, agent, host)) and the guard trigger: an `action.allowed` whose
+   `body.action` or `body.operation` GLOBs `'grant.*'` aborts unless the actor is (NULL, 'grant').
+   `SCHEMA_VERSION` 3j, a migration test with a step that fails partway.
+2. **Grant event writer.** A private session-less broker writer for guarded events. `#event` doesn't change.
+   `recordEvent` refuses `reserved-event` for the guarded namespace.
+3. **The `grant` raise frame.** `decision.raise` takes `grant` only with `credential.mint`, only from the chief
+   (`grant-chief-only`), and in row a only with `method: 'host-enroll'`. Any other method refuses
+   `invalid-request` until row b adds `host`. E1's checks, the `ssh-keyscan` set compare before the raise
+   transaction, and the rendered block.
+4. **Enrollment executor.** `#consumeGrant`, the start on the human's cli yes (X1), E2 steps 1 to 4, the
+   installer key at `<configDir>/secrets/hosts/<business>/<hostId>/installer`, the failure cleanup, and the
+   start reconcile for enrollments: the `registry` step undo, and a resolved-yes unspent enrollment ending
+   `grant.failed interrupted` (X3).
+5. **`hosts.check` and `hosts.remove`** (E4), with `mosaic hosts status|check|remove`.
+6. **`tools/host/`**: `mosaic-keys`, `mosaic-keys-write`, `mosaic-keys.sudoers`, `mosaic-keys.sshd.conf` (E3).
+7. **`host.run` on the store** (X4 first and third bullets): it reads the `hosts` and `host_grants` records
+   and the Approve record check, and at start the runtime gives `Credentials` a reference per `host_grants`
+   record. The loader refuses `hosts` at the top level and in a role (S1). Row 210's tests move to store
+   fixtures.
+8. **Reader filter** (duckworth-0067 N1): every grant-evidence reader in this row (status, the start
+   reconcile, `openGrantDecisions`) filters `kind = 'action.allowed' AND actor_role IS NULL AND actor_run =
+   'grant'`, with a test that an `action.refused` look-alike and a session-written one are ignored.
+   `hosts.remove`'s `hostLineLeft` reader is one of them (duckworth-0079 M4).
+
+Row b keeps the `host` method's raise binding (R4), the grant executor (X2), the grant rows of X3, X5,
+`Credentials.register`/`claim`/`abortClaim`, revoke (section 6) and `sweep`. So row a has no way to make a
+`host_grants` record outside a test fixture, and from its landing to row b's no agent holds a host grant
+(r6 N9, the run sheet strips row 210's keys).
+
+Tests in row a (r6 section 10): G1 and G5 for the `host-enroll` raise, G6 and G10 for the enrollment
+executor, G11's enrollment cases, G14, G15, G16, G17, G18, G20, G21 (its `host-line-left` case reads an
+event fixture until row b writes `hostLineLeft`), G25, the migration test, the trigger cases, the reader
+filter test, and row 210's T-tests on store fixtures. Row b: G2 to G4, G7 to G9, G11's grant cases, G12,
+G13, G19, G22 to G24, G26 to G28.
+
+## Early check items (duckworth-0079, REVIEW-build-split.md 10672772e on `duckworth/reviews`)
+
+Moves into row a:
+- M1. G4 for the `host-enroll` block (r6:240-242): a question can't forge the block, and the 4096-character
+  limit holds with the block appended. G4 for the `host` block stays in row b.
+- M2. The tag function (r6:265-266), because E2 step 2 tags the installer line. G24's first sentence moves
+  here: names of 64 characters with `.` and `_` give distinct tags of the fixed length. The `sweep` half
+  stays in row b.
+- M3. A store-fixture test that `host.run` refuses `host-not-granted` for no record, an unresolved decision,
+  a decision resolved by an arbiter, the tester or an agent or not via cli, a consume record with operation
+  `grant.host-enroll` in place of `grant.host`, and an unspent decision (X4 first bullet, r6:593-596). A
+  restart test that a `host_grants` fixture gives `Credentials` a reference (X4 third bullet).
+
+G21's `host-line-left` case:
+- F1. The fixture goes through this row's private grant writer in the real shape: `action.allowed`, actor
+  (NULL, 'grant'), `body.action` 'grant.failed', `body.host`, `body.hostLineLeft`. No raw SQL around the
+  trigger.
+- F2. `hosts.remove` reads `body.hostLineLeft` from any guarded body, not only `grant.failed`.
+- F3. Decided: a guarded body that carries `hostLineLeft` also carries `host`. Row b adds `host` to
+  `grant.revoke.closed`, so its body is `{tag, host, hostLineLeft}` (r6:716 has `{tag, hostLineLeft}`).
+  The reader matches on `body.host`, and doesn't map tags back to hosts through `grant.step`. A direct
+  field is one equality in SQL, and a tag lookup would add a second reader that the N1 filter also has to
+  cover.
+- F4. Row b carry: "no later `sweep` cleared it" (r6:403) needs `grant.sweep`, which only row b writes. Row
+  b adds the sweep clear to `hosts.remove` with a G21 case, and its G8 or G13 shows `hosts.remove`
+  refusing after a real `hostLineLeft` write, not only after the fixture. Until then row a's check is "any
+  guarded `hostLineLeft` for this host refuses".
+
+## Mutants (r6:838-883, numbered here)
+
+Row a, killed on this row's tree:
+
+| # | Mutant |
+|---|---|
+| A1 | drop the chief check |
+| A2 | start the executor on a `credential.mint` with no `grant` |
+| A3 | start it on an arbiter resolve |
+| A3b | start it on a `cli` yes by someone other than the human (duckworth-0083 N8) |
+| A4 | start it on `no` |
+| A5 | skip the keyscan compare |
+| A6 | compare only one key |
+| A7 | write the private key into the event body |
+| A8 | drop the "not yet enrolled" check in E2 step 1 |
+| A9 | drop the `hosts` primary key |
+| A10 | skip the start check for a resolved, unspent enrollment decision |
+| A11 | `host.run` reads the business file instead of the grant record |
+| A12 | build the tag without the business |
+| A13 | drop `from=` in the writer |
+| A14 | let the writer touch a line outside the tag pattern |
+| A15 | drop `O_NOFOLLOW` on the user file |
+| A16 | drop one group from the writer's refused list |
+| A17 | drop the user pattern check before the path use |
+| A18 | treat a `privileged` entry as enough without `users` |
+| A19 | let the writer accept a sudo user not in `privileged` |
+| A20 | trigger: drop the `body.operation` arm, so the consume record passes from a session |
+| A21 | trigger: accept actor_role NULL with any actor_run |
+| A22 | a grant reader drops the `kind = 'action.allowed'` or actor filter. The runner splits it: A22a drops the kind, and G21's `action.refused` look-alikes kill it. A22b drops the actor, which the trigger can't stand in for, because 3i-3j adds the trigger without checking old rows. Its killer is the grant-migration test "A22b, sage-1703": a session-written `grant.host.removed` with `hostLineLeft` and a `grant.host-enroll` row from 3i, migrated to 3j, where `hosts.remove` still removes the host and `reconcileGrants` ends nothing |
+| A23 | `host.run` skips the Approve record check (any `host_grants` record is enough) |
+
+Row b keeps the rest of r6's list: the `ready` check, the three hash compares, the definition check, the
+install and record order, `remove` on a verify failure, both start sweeps, the reconcile's remote `remove`,
+the `grant.step` before install, revoke leaving the record, `register` before `issue`, the abort check and
+the `await` before `issue`, revoke and an unreferenced claim, `sweep` and any `mosaic-` line, revoke's host
+step order, claim before consume, the resolved unspent grant decision, an async `commit`, `hosts.revoke`
+through `credential-verbs.mjs`, the revoke marker reconcile, the upsert, the undo past `grant.revoked`, the
+abort after step 5 and a missing `bus.tester` as dev.
+
+## Broker functions this row touches (sage-1677)
+
+For row 236 (Megavolt), which rebuilds on this landing. Old lines are `packages/bus/src/broker.mjs` at
+8fede5fc6, new lines are at the last commit that changed this file (they moved by 10 after `runEnrollment`
+went in). The planned list is kept in this file's history (827b89ea6).
+
+Changed:
+- `constructor` (:279): one more option, `hostGrant`, the object `host-grant.mjs` builds.
+- `recordEvent` (old :1243-1251, new :1606): one more refusal. An `action.allowed` whose `body.action` or
+  `body.operation` is a `grant.*` name refuses `reserved-event`.
+- `request()` (old :1362, new :1726): two routes ahead of the sync path, a `decision.raise` with `grant` to
+  `#raiseGrant` and the `hosts.*` verbs to `#requestHosts`. Both are async.
+- `requestHost` (old :1712-1795, new :2079): the business-file lookups (old :1730-1736) become one
+  `#hostAccess` call, in the same transaction as `#agent`. `commands` and `entry` come from it.
+- `#dispatch` (old :1796, new :2160) gets a fifth parameter, `enroll`, which only `#raiseGrant` passes.
+  - `decision.raise` (new :2244): `grant` joins the allowed keys, and `grant` without `enroll` (or the
+    reverse) refuses `invalid-request`. The `host.sudo` block reads `#hostAccess` in place of `b.hosts`
+    and the role's `hosts`, and an undefined `target` still refuses `host-unknown`. `validArgv` and
+    `validStdin` now run after the access check, so a malformed argv for an ungranted host refuses
+    `host-not-granted` first. The enrollment block is appended to the question before `string(question)`,
+    so the 4096 cap counts it (M1). The decision's raise body carries `grant: enroll`.
+  - `decision.resolve` (new :2409): when `op` is `resolved`, `#approvedGrant` reads the decision, and a
+    `host-enroll` grant starts `#runEnrollment` from `setImmediate`, after the transaction commits. The
+    result adds `grant: 'started'`.
+
+New, all private but two:
+- `#grantEvent` (:657), the writer of guarded events. It runs the secret check, then `writeGrantEvent`.
+- `#approvedGrant` (:667), `#consumeGrant` (:678). `#consumeGrant` sits after `#approvedGrant`, not next
+  to `#consumeAuthority` as planned.
+- `#hostRecord` (:685), `#hostAccess` (:692), `#grantNotice` (:708), `#enrollFailed` (:736),
+  `#runEnrollment` (:750), `#openGrantDecisions` (:823).
+- `runEnrollment` (:745), public, a trusted entry to `#runEnrollment` for G10. No verb reaches it.
+- `reconcileGrants` (:833), public, which `runtime.mjs` calls once at start.
+- `#raiseGrant` (:866), `#hostsCaller` (:886), `#requestHosts` (:900), `#hostLinesLeft` (:964).
+
+Module level, new (:184-230): `GRANT_RUN`, `grantName`, `GRANT_EVIDENCE` (the N1 filter as SQL),
+`registrySha256`, `writeGrantEvent` (exported, the one writer of guarded events, which test fixtures use
+for F1), `HOSTS_VERBS`, `fingerprintOf`, `INSTALLER_COMMENT`.
+
+Unchanged: `#event`, `#spent`, `#consumeAuthority`.
+
+Other `src` files:
+- `bus/src/host-grant.mjs`, new: the keyscan, the installer key pair, and `hosts.check`'s `list`.
+- `bus/src/runtime.mjs`: builds `hostGrant`, calls `reconcileGrants` before the server starts, and adds
+  the `host_grants` references before `new Credentials` (X4 third bullet).
+- `bus/src/host-run.mjs`: `runHost` takes `command`, sent as is in place of the sudo argv, for the
+  installer's `list`.
+- `bus/src/server.mjs`: the `hosts.*` verbs and a raise with `grant` go down the async path.
+- `bus/src/store.mjs`: the 3i-3j step, `SCHEMA_VERSION` 3j. `bus/src/credentials.mjs` exports
+  `privateDir`.
+- `business/src/business.mjs` and `business/src/hosts.mjs`: the loader refuses `hosts` (S1).
+  `checkHosts` and `checkHostGrants` are gone.
+- `cli/src/hosts.mjs`, new, routed from `cli.mjs` and `scripts/mosaic`.
+
+## Decisions taken in the build
+
+- **`#hostAccess` binds the agent and the host.** X4 says the Approve record check passes when the
+  decision is an approved `host` grant with a `grant.host` consume. The check also requires the grant's
+  `agent` to equal the session's role and its `host` to equal the requested host. Without that, an
+  approved grant for one agent and host would vouch for any `host_grants` row that names its decision.
+  Cost: none for row b, whose executor writes the row from the same grant.
+- **Store fixtures are written the real way.** `bus/tests/host-fixtures.mjs` inserts the decision rows by
+  SQL, but every guarded event goes through `writeGrantEvent`, so the trigger sees it (F1). An enrollment
+  fixture writes `grant.host.enrolled`, or the start reconcile reads it as interrupted.
+- **The resolver test for host kinds is gone.** `business/tests/hosts.test.mjs` lost its D5 case, because
+  the loader now refuses `host.<id>` credential refs. The `isHostKind` filter in `business/src/resolve.mjs`
+  can't be reached now. I left it in, since row b may want it back, and it's one line.
+- **Store before Credentials.** The runtime already opened the store before `Credentials`. The
+  `host_grants` references depend on that order, and the comment there says so.
+- **CLI.** `mosaic hosts` prints tab lines, and `--json` prints the bus rows. Usage errors exit 4 and bus
+  refusals exit 2, as `mosaic credentials` does. There is no enroll command: enrollment is the chief's raise.
+- **Host tools tests live in the bus suite.** `bus/tests/host-tools.test.mjs` loads the writer by path
+  through a Python harness under `python3 -B -I`. The harness passes its own key dir, config dir, owner
+  uid and user, group and sudo lookups, and runs `mosaic-keys` from a copy with stub `sudo` and `logger`.
+  The gate runs the bus suite, so G16 and G25 run there. The real `pwd`, `grp` and `sudo -l` paths are
+  checked on the #433 VM, not here. The test also runs `visudo -c` on the sudoers file and `sshd -T` on
+  the drop-in.
+- **Writer details the design left open.** The `from` file must hold exactly one value matching
+  `[0-9A-Za-z.:/*?!_-]+(,[0-9A-Za-z.:/*?!_-]+)*`, so it can't close the quote. `users`, `privileged` and `from` must be
+  regular, owned by the owner uid and not group or world writable, and are opened without following a
+  symlink. Lines starting with `#` are comments. A refusal exits 1 with its code on stderr and in syslog.
+  `add` of a tag that is already there exits 0 and writes nothing.
+- **`runEnrollment` is public for G10 (duckworth-0081 B1).** G10 needs a second start for a spent
+  decision, and the resolve path can't give one: a second resolve refuses `decision-closed`
+  (broker.mjs:2416) before the executor runs. So
+  `#runEnrollment` returns its code (`enrolled`, `host-enrolled` or the refusal), and a public
+  `runEnrollment` calls it, as `reconcileGrants` is public. The test checks a spent
+  decision gives `decision-consumed`, and an open or agent-resolved one gives `not-authorized`, with
+  nothing written. That second case also reaches the `via` and `by` checks in `#approvedGrant`, so A3 is
+  no longer vacuous (N1).
+  Who can call it (sage-1692): only code holding the `Broker` object, which is the bus process and the
+  tests. The one `new Broker` in `src` is `runtime.mjs:126`, and no `src` file calls `runEnrollment`;
+  the resolve path calls the private `#runEnrollment` from `setImmediate` (broker.mjs:2445). A seat
+  holds no `Broker`. It reaches the bus only over `broker.sock`, where `server.mjs` calls a fixed set of
+  methods by name (`request` at :134 and :140, `identity`, `disconnect`). `request()` routes on the verb
+  through the `#dispatch` switch, and neither file looks a method up by name (no `this[` in either), so no
+  verb string can reach `runEnrollment`.
+- **A `sudo -l` that times out refuses `user-sudo` (N2).** `_sudo` returns an empty answer on
+  `TimeoutExpired`, which isn't the expected line, so `main` logs the refusal and exits 1.
+- **Keyscan comment (N3).** A scan that can't start refuses `host-failed`. One that runs and finds no key
+  returns no lines, and the raise refuses `host-key-mismatch`. The comment in `host-grant.mjs` now says so.
+- **No tag on in-run `grant.failed` (N4).** r6:578 tags only the `interrupted` one, so the code follows it.
+- **Run sheet (N5).** The writer refuses `config-privileged` when the file is missing, so each host needs an
+  empty, root-owned `/etc/mosaic-keys/privileged` (0644) before the first enrollment.
+
+## Mutant results (Sage's slot, 2026-10-21)
+
+All 25 killed: A1 to A23, with A3b added for duckworth-0083 N8 and A22 split into A22a and A22b. The
+runner is `mutants.py` outside the repo. Each mutant gets its own session, a 420 s limit with a group kill,
+and a byte restore checked against git status. None hung. Run 1 (04:24Z, on 95f966b1c) killed A1 to A22a
+and stopped at A22b, which survived. Run 2 (04:43Z, on 097892741) killed A22b and A23.
+
+- Each kill comes from a named assertion in the mutant's own test files, except A9. Dropping the `hosts`
+  primary key leaves `host_grants`' foreign key with no parent key, so the store refuses to open
+  ("foreign key mismatch") and 28 of 29 tests fail at setup. That's a structural kill, not the S1 test.
+  The schema can't exist without the key (sage-1709).
+- A22b drops the actor filter from `GRANT_EVIDENCE`. The trigger can't stand in for it, because a 3i store
+  can hold a session-written grant row that the 3i-3j step keeps. The grant-migration test "A22b,
+  sage-1703" kills it (see the A22 row above).
+
+Follow-up, not in row a: G18's control calls `runHost` directly, so nothing runs `hg.check` end to end
+with a good pin (duckworth-0083 N9). The #433 VM run covers it.
+
+## Status at 097892741
+
+Done: every Split item, 1 to 8, duckworth-0081 B1 to B3, duckworth-0083 N8, and all 25 mutants killed.
+
+Single files in the slot, all exit 0, 178 pass and 0 fail by an awk sum over 23 logs: bus grant-enroll
+24, host-run 24, grant-migration 6, host-tools 6, account-migration 3, chief-of-staff 18,
+comment-migration 5, hard-waits 13, name-migration 1, project-runtime 3, spec-migration 1,
+thread-migration 3, usage-migration 1, project-files 8, spec-socket 6, spec-review 12, land 17, spec 4;
+harness spec-tools 2, raise-domain 2; business hosts 4; cli hosts 5; seat sandbox 10.
+
+Left: Sage runs the whole bus, business and cli suites and every `scripts/test-*.sh` at the landing gate,
+after Duckworth approves.
+
+## Round 3 (sage-1742): two tests that count the schema
+
+The landing gate failed `packages/bus/tests/schema.test.mjs:522`. It counts the tables and triggers that
+`schema.sql` creates, and row a adds two tables and a trigger, so the counts go from 16 to 18 tables and
+from 70 to 71 triggers. My singles didn't run it because I took it for a test of other rows' tables.
+
+I grepped `packages/*/tests/*` for `sqlite_master` and `schema.sql`, with `schema.test.mjs:517` as the
+positive control. That turned up one more test that would fail: T46 in
+`packages/cli/tests/stack-release.test.mjs:910`. It puts every schema table in exactly one of four lists, and
+hosts and host_grants were in none. I'd left the stack-release tests out of the r2 singles on the claim that
+they don't load the bus, but T46 reads `schema.sql`. Both tables go in its untimed list (Sage's ruling,
+sage-1745: the message_threads pattern). Neither has an `at` column. Row a writes hosts at five lines,
+and each runs in one store transaction with a `grant.*` events row, which the restore guard counts.
+`#grantEvent` (broker.mjs:657) writes that row through `writeGrantEvent` (:201, INSERT INTO events at
+:212).
+
+- :737 DELETE, in `#enrollFailed`, with grant.failed at :738. Both callers wrap it in a transaction,
+  :816 and :849.
+- :763 INSERT, in the step 1 transaction (:754), with grant.host.enroll.step at :761.
+- :783 UPDATE installer_fingerprint, in the step 4 transaction (:780), with grant.host.enrolled at :784.
+- :932 DELETE, in the hosts.remove transaction (:927), with grant.host.removed at :933.
+- :950 UPDATE state ready, in the hosts.check transaction (:944), with grant.host.checked at :951.
+
+Row a writes no host_grants rows. It only reads them (broker.mjs:695, :930, runtime.mjs:103). Row b adds
+the writes, and each must share a transaction with a `grant.*` event the same way. That goes on row
+235's carry list. The other hits pin an older schema
+(account, comment, name, spec, thread and usage migrations, chief-of-staff 3c) or count only their own
+tables (state.test.mjs:106 reads every table but pins no list, threads.test.mjs:129).
+
+hosts and host_grants are mutable by design, so the refused-labels loop above `schema.test.mjs:517` gets no
+entry for them. hosts.check updates a host to ready. hosts.remove and a failed enrollment delete the
+record. Row b updates and deletes grant records. Neither table has append-only triggers. The one new
+trigger, events_grant_actor, guards events. grant-migration.test.mjs tests it, and it killed mutants
+A20 and A21.

+# Row 230: C2-13a unit render and host precheck
+
+Gitea #1732. Vikunja #416 (track T2). Brief: docs/plans/2026-10-20_case2-rows.md, section "C2-13a",
+blob f6b4933f0f47 (01b40d357, sage-1562). Base: 00d4cc1f6 (row 190). Reviewer: Webby. Gate: the cli
+suite plus every scripts/test-*.sh.
+
+## What ships
+
+`scripts/case2-unit.sh` renders `[email protected]` and `mosaic-webui.service` from the two existing
+templates into the system unit directory, for the default instance only. It writes each unit through
+a temp file at mode 0644, runs `daemon-reload`, enables both units, starts the bus and then the
+Console. If the bus fails to start, the script refuses and leaves the Console unstarted. Both units
+get `WantedBy=multi-user.target`, and neither gets `After=` or `Wants=`. The script never links a unit
+file into place. A re-install refuses unless each installed unit passes the same checks, both units
+name one copy, and each equals the render apart from the copy id.
+
+`--profile library` (the default) refuses `--pm`, `--claude`, `--tester-port` and `--sso`, and needs
+the preview proxy flags plus the proof pair. `--profile factory` refuses the six proxy flags and takes
+`--pm` and `--claude`. Both refuse `--checkout` and `--board`.
+
+`scripts/case2-precheck.sh --business ID [--profile factory|library]` runs as `<user>`. It prints one
+`ok` or `REFUSED` line per check and exits 1 if any check refused. It prints variable names only,
+never values.
+
+`packages/cli/README.md:713` now says nothing creates the session env file, only the Case 2 precheck
+reads it, and the precheck prints only variable names (webby-0034 N2, webby-0035).
+
+## Deviations for review
+
+Sage accepted all six for the build (sage-1570). Webby rules on each.
+
+1. The precheck takes `--business ID`. The brief names no other way to find the business file.
+2. A run root `<dataRoot>/launches/<business>` that doesn't exist passes, with a note that the first
+   launch creates it at 0700 (session.mjs:47 and newRun). A symlink refuses, and so does an existing
+   entry that isn't a 0700 directory.
+3. The claude marker check passes when the reply holds the marker and input plus cache tokens are at
+   most 2000. **The 2000 ceiling is unmeasured.** The tests use fakes at 40 and 9000 tokens. Measuring
+   it on a real claude belongs to row 195's install run, not this row.
+4. A non-root test can't create a root-owned proof file. For the "proof not owned by the user" case,
+   the fake getent reports another uid for the user, so the user's own file reads as someone else's.
+5. The unit script refuses `%h` left in any unit, rendered or installed. A system unit expands `%h`
+   to root's home. The render replaces every `%h`, so the test edits an installed unit to reach it.
+6. With `--auth-header X-Authentik-Uid`, the allowed user must be 64 lower-case hex characters (lead
+   decision 101). The test covers both the refusal and the pass.
+
+## Tests (packages/cli/tests/case2-unit.test.mjs, 30 cases after round 2)
+
+The tests use a scratch unit directory and a scratch home, plus fake systemctl, getent, sudo, id,
+node, bwrap and claude. They never touch /etc/systemd, ~/.mosaic-dev, ~/.config/mosaic-dev or a
+live unit. Every precheck case asserts its output doesn't hold the fixture key.
+
+- Unit: the clean library render, PATH for a node outside the default list and for /usr/bin/node, the
+  systemctl order, a failed bus start, no `systemctl link`, factory `--pm` and `--claude` rendered and
+  absent, re-install to another copy, edits to an installed unit, template restrictions,
+  EnvironmentFile placement, unknown tokens, PermissionsStartOnly and `+`/`-+` Exec prefixes,
+  symlinked unit paths, bad `--node`, re-install drift, a split copy pair, bad copy ids, every library
+  and factory flag refusal, and bad `--claude`.
+- Precheck: a good host, node older than 24, more than one group, sudo succeeding, XDG_DATA_HOME,
+  HOME mismatch, a run root mode, a bad config, bwrap failing, the port floor at or below the Console
+  port, a missing Console unit, bus.tester per profile, profile-library-business, the claude check
+  (no route, replaces, appends, missing, the unit's MOSAIC_CLAUDE_BIN beating PATH), and the session
+  env file (missing, 0644, symlink, empty, emptied by a later line, quoted).
+- Bind (mos-1100): inside `binds()` plus `sandboxArgv()`, a bind on port 980 gets EACCES, and a bind
+  on a free port of 1024 or above succeeds. The test fails if the host's floor is at or below 980.
+
+## Verification
+
+Round 1 singles, run before the gate: case2-unit.test.mjs passes 28/28 with no skips, and host.test.mjs (it
+reads the cli README) passes 42/42. No test pins a hash of the README. No other test reads the two
+scripts.
+
+## Round 2 (webby-0046, sage-1589, sage-1590, sage-1591)
+
+Base: origin/refactor (rebased from 00d4cc1f6; the 15 commits between touch none of the five paths
+or the two unit templates). Branch gosalyn/c2-13a-r2.
+
+B1. The precheck now has a case for each refusal Webby named: the user missing from passwd (:77),
+a business file that is unparsable, missing or fails the schema (:137), a run root that is a symlink
+to a 0700 directory (:151), a Console ExecStart with no --port (:179), an unreadable port floor
+(:180), a claude reply without the marker (:223) and a claude reply that isn't JSON (:224). The fake
+claude gained `nomarker` and `text` kinds. The no-claude-code case and the missing-claude case share
+a PATH without `/usr/bin/claude` (`pathWithoutClaude`), so the no-claude-code case now shows a host
+with no claude passes.
+
+N1 (ruled in for this round). Before writing, `case2-unit.sh` asks `systemctl is-active` for both
+units. For each unit that was running, it prints that the unit is still on its old copy, never
+"started", and then that the bus and Console must restart together to reach the new copy. A unit
+that wasn't running gets "started ... on copy". A fresh install prints the round 1 line. The script
+still restarts nothing. The new test covers both units running and only the Console running.
+
+N4. The README line at :713 is rewrapped.
+
+Mutants, run in Sage's slot on a scratch worktree, one branch each: :77, :137, :151, :179, :180,
+:223, :224, a precheck that refuses with no claude on PATH (for the no-claude-code case), and an
+install that prints "started" for a running unit (sage-1591).
+
+## Carry items for row 195
+
+- N1's restart. Row 195 restarts the bus and Console together after a re-install over running
+  units, as the install line now asks.
+- N2. A system drop-in check like `bus-service.sh:122-145`, so a drop-in under
+  `[email protected]/` or `mosaic-webui.service.d/` can't change what the checked unit runs.
+- N3. The precheck finds claude on the shell PATH. The bus unit's `PATH=` is what a session uses
+  when `MOSAIC_CLAUDE_BIN` is unset, so the check should search that PATH.

+# Row 197 execution ledger
+
+Plan: MANIFEST.md r2, approved by Webby ca6b32d66.
+Build grant: sage-1390. Suites, image builds and paired proof are not granted.
+Rebased five documentation commits onto origin/refactor aa1bd209e before code.
+Existing worktree herb/row197 and plain node_modules symlink retained.
+
+- T1 preflight/steps: in progress.
+- T2 locks/status/recovery: pending.
+- T3 image/Docker: pending.
+- T4 fixtures/timing: pending.
+- T5 evidence/acceptance: historical timing done; implementation pending.
+
+Preflight interfaces: T1 RunPaths supplies T2 ownership and T3 image checks.
+T2 run receipt supplies T4 lane/port state and T5 attribution. T3 image identity
+is checked before Docker-bearing steps. T4 timings supply T5 pair summaries.
+No interface conflict found. No product API or assertion changes are authorized.
+
+Ruling: use this approved BUILD.md as the execution ledger, rather than adding
+skill workspace paths outside the manifest. This preserves the reviewed path
+boundary. Missing ledger detail would cost recovery time, not product behavior.
+
+## Implementation checkpoint 2026-10-20T20:11:58Z
+
+T1-T5 source is present within the approved manifest. Full acceptance is pending.
+Fresh single-file checks: preflight/supervisor 6/6; state/recovery 11/11; image and
+Docker guard 4/4; port leases/attribution/proof summary 3/3. No skips or failures.
+Existing files checked singly: board serve; WebUI serve, preview, proof-cli,
+tester-cli and service; harness pi and Claude. Stack-release R1 selected single
+passed 1/1. WebUI service also passed 31/31 with lane-a leases and a 30-byte root.
+All existing assert lines are unchanged. Shell syntax and diff checks pass.
+
+Observed defects fixed during the single-file cycles: cancellation incorrectly
+returned zero when a TERM handler exited zero; recovery did not supersede an
+unclean terminal; status omitted the lock-before-receipt window. Evidence logs
+retain the failing and passing observations. Source still has no commit because
+applicable suites have not run. No image build, proof, push or live operation.
+
+Ruling: use an instrumented single-lane author gate on a frozen dirty-source
+clone before committing source. The new wrapper requires a clean candidate and
+proven image receipt, while repository rules require green suites before source
+commits. The author gate retains every suite and assertion, caps concurrency at
+two, uses own port/state/temp/project roots, and guards Docker against builds.
+Cost if wrong: the author gate fails; clean-candidate wrapper baselines and the
+paired proof remain mandatory after source is verified and committed.
+
+Ruling: publish the initial run directory atomically after the start receipt is
+complete. This avoids a second lane observing a partially written start. A
+crash before publication has started no test or mutable Docker operation.
+Cost if wrong: a lane refuses or quarantines; no protected state is bypassed.
+
+## Implementation review corrections, 2026-10-20T20:33Z
+
+Webby-0029 reviewed the first implementation packet at f942bd7d4.
+B1 identified missing manifest tests. B2 identified a test that leased both real
+bands through a private lock namespace. The old author-gate clear was withdrawn
+in herb-0019. SOURCE.json, BUILD.patch and gate.sh still describe the old frozen
+clone. They are not a clear for the edited working tree. No author gate ran.
+
+B2 correction: the helper test uses only the active lane and MOSAIC_GATE_STATE.
+It compares the other band arithmetically and has no unasserted listener. The
+occupied-port probe first obtains its own real lease, binds that port, and
+asserts that its sentinel listener survives refusal. No test reserves another
+lane's band. Exhaustion narrows only the test process's band to one owned port.
+
+B1 coverage added within the existing approved paths. No case is dropped:
+
+| Manifest case | Added check |
+| --- | --- |
+| T1 canonical and builder checkout, existing output | gate-lane.test: direct validateRun refusals |
+| T1 92-byte socket and over-107-byte socket | exact design example with a distinct gt- test root; 108-byte refusal |
+| T1 both candidates carry tooling | validateTooling compares each launcher file, including missing and changed cases |
+| T1 duplicates and NODE_TEST_CONTEXT | repeated package/script fixture is retained; sanitized environment is exercised by both supervised children |
+| T2 one-winner race and inherited FDs | two actual shell wrappers race; a controlled supervisor verifies held FDs, and its child checks that no FD points to either lock file |
+| T2 same checkout and legacy claim refusal | activeConflicts uses synthetic process observations with a live lane and a sibling landing gate |
+| T2 surviving child and interrupted recovery | locked recovery kills a child proven by the private root, preserves a foreign child, is killed during fake Docker cleanup, leaves quarantine, and resumes under a new fixture grant |
+| T3 missing receipt and missing image | verifyImage refuses absent provenance and failing inspection |
+| T3 tag changed mid-gate and at gate end | runGate now uses the same executePinnedSteps boundary exercised by the tests; the next step never runs after a changed ID |
+| T3 mutable-tag rebuild | fake preparation returns a new image ID with identical input digest; the old receipt refuses it |
+| T3 cold and warm counters | preparation records one build and its time; warm execution records zero builds; repeated verification never builds |
+| T4 parallel test-file leases | two generated Node test files hold ports in the same lane/state; locks are checked during child execution and shutdown |
+| T4 exhausted band, occupied port and foreign listener | a one-port process-local band refuses both a held lease and an existing sentinel listener; the listener survives |
+| T4 owner death | a killed allocator releases only its own holder; a foreign lease remains held |
+| T4 lease through child shutdown | parent probes the lock while the fixture test runs and after its child has stopped |
+| T4 fixtureCacheEnv | replacement child environment writes only under separate tmp, jiti and cache directories |
+| T5 unrelated session append | a separate process waits for a running-step barrier, appends under a fixture HOME, and remains unrelated in the resulting metadata attribution |
+
+N1 removes the unused closed binding. All leases reserve an unbound endpoint;
+existing closed options need no call-site change. N2 makes child TMPDIR a tmp
+subdirectory. N3 normalizes ss interface scopes before checking port 9. N4 uses
+gt- for unit run roots. N5 documents the canonical node_modules dependency.
+N6 is recorded: row 200 also edits stack-release.test.mjs; the second landing
+must rebase and rerun that file singly. Sage was told in herb-0019.
+
+Before Sage's hold, expanded preflight tests passed 11/11, state tests 14/14,
+image tests 7/7, and the pi/Claude singles passed 8/8 each with separate tmp
+subdirectories. Later source/test edits still need verification. In particular,
+the new parallel test-file probe had a cleanup-order defect and is unverified.
+Its root cleanup ran before child shutdown. Cleanup now stops children before
+removing their root. Output is retained for a useful failure report. The initial
+FD probe also assumed Node did not reopen FD numbers; it now checks the actual
+lock targets. The early passing fixture file covered child allocators, before
+they were changed to actual generated test files. It is not acceptance of the
+latest file.
+
+Sage-1448 stopped all node --test runs at 20:30Z for Rocko's browser slot.
+The remaining owned process tree was stopped at 20:30:32Z. Inspection found no
+remaining owned test processes afterward. Edits and static inspection continue.
+20 module syntax checks, shell syntax and git diff checks pass. Existing-file
+assertion lines remain identical to HEAD. No test is run during the hold.
+
+Next: after Sage passes Rocko's clear, verify the corrected files singly,
+including a lane-env helper-file check. Then refresh the frozen clone and all
+three packet artifacts, send their hashes, and request a new author-gate clear.
+Suites, image builds and paired proofs still need their own grants. No source
+commit, push, suite, real Docker build or paired proof has run in this phase.
+
+## Refrozen review packet, 2026-10-20T20:41Z
+
+Sage-1454 lifted the single-file hold. Fresh runs passed without failures or
+skips: review-t1-resume.log 11/11, review-t2-resume.log 14/14,
+review-t3-resume.log 8/8, review-t4-resume.log 8/8. The helper file also passed
+8/8 with lane-a environment in review-t4-lane-a.log. Its retained state had only
+an a port-lock namespace, no b directory, and every lock was released. Generated
+fixture Node test entries explicitly use --test-concurrency=2. The child-test
+probe now finishes and cleans up before removing its root. All 41 new tests pass.
+
+B1 and B2 fixes are ready for Webby's review. No manifest case was dropped.
+All 25 source paths were copied to a new frozen clone and compared by mode and
+SHA-256. This supersedes the earlier withdrawn source packet:

+verified every source hash/mode and patch result, and all B1/B2 cases. No queue
+review request comment exists yet; Sage owns creating it if needed.
+
+Folded all three optional notes into the same approved paths. The helper file's
+standalone fallback now shares /mnt/storage/scratch/mosaic-gate-lanes with real
+lane-a leases and leaves its stable lock files in place. Band assertions use the
+imported BANDS. Both T5 polling children fail after five seconds if their barrier
+is missed. README records the shared standalone namespace and deadlines.
+
+Fresh single-file logs review-r3-fixtures.log and review-r3-lane-a.log both pass
+8/8 with zero skips. The lane-a run has no b lock directory, and every lock was
+released. Syntax and diff checks pass. No existing test assertions or timeouts
+changed. Remaining source matches the 11/14/8-file checks from r2.
+
+Refreshed all 25 source rows in the existing frozen checkout. New digests replace
+the preceding r2 packet. gate.sh and its command are unchanged:
+
+- SOURCE.json: 3584763642506e81a532c839bdd07b111d25daa87e35dbe441d8e8c01a2c2aab

+
+Author gate remains unstarted and queued for Sage's explicit grant. No source
+commit, suite, image build, paired proof, push or branch deletion ran.
+
+## R3 approval receipt
+
+Webby-0033 approved r3 in REVIEW-impl-r3.md at a5643f9bd. Static review verified
+the three packet hashes, all 25 source rows, and the patch result. Their review
+accepts N1-N3; no additional hang-guard test is requested. No queue review request
+comment exists yet, so Webby has not recorded a queue review.
+
+Read-only verification after receipt confirms that the approved packet hashes
+and all 25 worktree/frozen source hashes and modes still match. Source and gate
+script stay frozen. The author gate has not started and still needs Sage's grant.
+
+## Queue review round 1
+
+Sage-1476 authorized moving row 197 to in-review before the author gate.
+Created CANDIDATE.sha256 from the same 25 reviewed SOURCE.json rows. Its digest
+is 6318f0d0bba9ee90ccaa3503cac8c2e04c6397f2ef6c3564f687fbc2092989e3.
+Ran the queue move from the canonical checkout with op herb-197-review-r3.
+The move succeeded at revision 2395, opening round 1 on #1695. The request post
+failed before send because MOSAIC_GITEA_CREDENTIAL_FILE is not set; revision 2396
+records the failed outcome. Exit code 1 describes the failed post, not a failed
+row transition. Read-back confirms state in-review and the correct candidate.
+Sage will post as jarvis and give Webby the request comment number. No credential
+lookup, alternate post or retry was attempted here.
+
+SOURCE.json, BUILD.patch, gate.sh and all 25 frozen source rows remain unchanged.
+Latest slot order is row 190 r2, 201, 204, 200, Gander, then Herb. No gate starts
+before Sage sends an explicit grant ID.
+
+## Follow-on assignment
+
+Sage-1503 assigns row 215, Case 2 C2-04, to Herb after row 197 (queue rev 2455,
+Gosalyn design r11). Read docs/plans/2026-10-20_case2-rows.md, C2-04 section,
+at 5b8def2f1 when starting that row. Its required base is origin/refactor
+305857c8f. This assignment does not replace row 197 or authorize its gate.
+Keep row 197's approved source frozen while awaiting Sage's grant. Start row
+215 only after row 197, using a new branch name under the existing fleet rule.
+
+## Round 2 merge preparation on row 233
+
+Sage-1757 replaces history replay with one candidate commit on 57f59e0c3.
+The attempted history replay on herb/row197-r2-233 had already finished when
+that instruction arrived. Its only conflict was the append-only BUILD-LOG tail.
+That branch remains for history; none of its replayed commits is in this round.
+The current branch is herb/row197-r3-233, directly from
+57f59e0c399ce29b1bb85ca6af686fdc10eb195d.
+
+Stash correction: shared refs/stash was used incorrectly. The exact entry
+2767b88549dfd8c7e810908b5416876fa50cb571 is now kept on
+herb/row197-r3-wip. After verifying stash@{0} still named it, only that entry was
+dropped. The two other entries remain. No further stash creation, force push,
+branch deletion or refs/stash mutation is planned. A separate working-copy
+backup is /mnt/storage/scratch/herb197-merge-W4oiLg.
+
+Sage-1760 requires preserving every landed hunk on every changed manifest path.
+Checked each of the 25 r1 paths with git diff aa1bd209e 57f59e0c3 -- PATH.
+Exactly three changed upstream. Their r2 diff against 57f59e0c3 is captured in
+r2-merge-only.patch:
+
+| Merged path | Only row 197 changes against landed base | Landed content retained |
+| --- | --- | --- |
+| packages/cli/tests/stack-release.test.mjs | leasePort and laneAfter imports; freePort now calls the lease helper | All landed tests, including row 233's tests after R15 and BACKUP_STORE checks |
+| packages/webui/tests/service.test.mjs | leasePort and laneAfter imports; closedPort now calls the lease helper | SEND_REFUSAL permits --sso; default unit rendering removes the @CONFIG_ENV@ line |
+| scripts/test-discord.sh | fixture PI_CODING_AGENT_DIR setup; optional two-worker nested Node cap | Row 190's absent scratch MOSAIC_CONFIG selection and caller-config restoration |
+
+The other 22 paths equal the r1 reviewed source bytes and modes. r2-MERGE.json
+lists every path, its r1/r2 digest, mode, upstream-change flag and equality result.
+Source copies came from the hash-verified r1 frozen checkout. Original r1 digest:
+6318f0d0bba9ee90ccaa3503cac8c2e04c6397f2ef6c3564f687fbc2092989e3.
+No existing assertion or timeout line differs from the landed base. Static
+checks only: 20 module syntax checks, four shell syntax checks and git diff check
+pass. BUILD-LOG.md equals 57f59e0c3 byte for byte and is outside this commit.
+
+Sage explicitly requested the local candidate SHA before granting tests. This
+commit is an untested preparation checkpoint, not gate evidence. No tests or
+push are authorized yet. r2-TEST-FILES.txt lists the requested grant scope:
+16 Node test files singly and scripts/test-discord.sh, test-foundation.sh and
+test-queue.sh. The four stack-release consumers are stack-release.test.mjs,
+stack-release-external.test.mjs, stack-upgrade.test.mjs and stack-instances.test.mjs.
+The shared stack-release-fixture.mjs is exercised by its importing test files,
+not run as a standalone test. This covers all 13 touched Node test files plus
+three additional stack-release consumers and all three touched shell suites.
+
+Current slot order from sage-1760: Gizmoduck, Launchpad, Darkwing, then Herb,
+around 06:30Z. Wait for an explicit grant. After granted checks and authorized
+push, build the new candidate manifest from that pushed tip and open the
+merge-scoped round 2. Old SOURCE.json, CANDIDATE.sha256 and gate.sh remain r1
+historical artifacts and are not a clear to run the merged candidate.
+
+## Round 2 rebuilt on row 234
+
+Sage-1776 names landing c771a36f4bd0b6c359282425c668996a90072f93.
+Built a new branch, herb/row197-r4-234, directly from that landing. No history
+replay, stash, force push, branch deletion, test run or push is involved.
+The prior candidate a3b7cbde8 remains untested and is not the queued candidate.
+
+Checked git diff --name-only 57f59e0c3 c771a36f4 against all 25 source paths.
+Only packages/cli/tests/stack-release.test.mjs overlaps; the other 24 do not.
+The full comparison is in r2-on234-OVERLAP.txt. The stack-release file starts
+from the landing and keeps both T46 untimed entries, host_grants and hosts.
+Its only changes against the landing are the leasePort and laneAfter imports
+and freePort's call to the lease helper. r2-on234-merge-only.patch records those
+hunks. Existing assertions and timeouts match the landing exactly.
+
+Every other source path equals a3b7cbde8 byte for byte and retains its mode.
+This includes the previously merged service and test-discord files, preserving
+all landed --sso, CONFIG_ENV and scratch-config handling. The earlier evidence
+r2-MERGE.json still records those three pre-234 merge cases. The new
+r2-on234-MERGE.json records each current digest, prior digest, mode and equality
+result. BUILD-LOG.md equals the new landing byte for byte and is excluded.
+
+Static check of the changed Node file and the candidate diff pass. No tests
+were run. The scope stays r2-TEST-FILES.txt: 16 Node files singly plus the three
+shell suites. No manifest or queue round is rebuilt until granted checks and
+authorized push. Old SOURCE.json, CANDIDATE.sha256 and gate.sh remain historical
+r1 evidence. The test slot follows Darkwing 240 and needs Sage's explicit grant.

+# Two-lane proof command and schedule
+
+This evidence stays outside r5's 32 manifest paths. No proof or image build has
+run. The driver and example config are committed on herb/row197-proof, rooted
+at 9aa6d52d9. Sage runs the committed copy from their own checkout.
+
+Driver: `agents/herb/work/queue-197/proof/run-proof.mjs`.
+The commit message to Sage carries its exact SHA-256. Check it with
+`git show <proof-commit>:agents/herb/work/queue-197/proof/run-proof.mjs | sha256sum`.
+
+After Sage fills config.json from config.example.json and grants the whole block:
+
+```sh
+MOSAIC_PROOF_GRANT=ACTUAL_SAGE_GRANT_ID node /SAGE_PROOF_CHECKOUT/agents/herb/work/queue-197/proof/run-proof.mjs /SAGE_OWNED_CONFIG/config.json
+```
+
+The example config pins the launcher and candidate A to 197 r5:
+9aa6d52d9431efd215aa31d748d7e273eb321474. The launcher is a separate clean
+checkout owned by Sage, so later row 215 work cannot change it. Fill candidateB with
+Sage's approved combined 212+197 commit, imageReceipt with the granted pinned
+image-provenance receipt, and runRoot with a fresh private scratch path. Both
+candidates must carry identical lane tooling and image inputs and use the same
+pinned image ID. The driver refuses missing parameters, equal candidate SHAs,
+dirty launcher, changed tooling, mismatched image inputs or image ID.
+
+D5 order is exactly two solo gates, then three pairs:
+
+| Wave | Candidate A | Candidate B |
+| --- | --- | --- |
+| 1 | solo, lane a | idle |
+| 2 | idle | solo, lane b |
+| 3 | paired, lane a | paired, lane b |
+| 4 | paired, lane b | paired, lane a |
+| 5 | paired, lane a | paired, lane b |
+
+Every invocation gets its own clean clone, output, short temp root and random
+Compose project. The wrapper discovers all package and shell steps, with two
+Node test-file workers per lane. The summary requires three overlaps, the lane
+swap, successful clean receipts and zero warm image builds. Raw logs and per-step
+receipts remain available. No failed gate or series is retried automatically.
+
+A live monitor stops both gates on the first failure line, records lane, step,
+source file when the runner emits it, test name and preserved log, then enriches
+that report after shutdown. If the runner gives no source path, the report says
+unresolved and points to the log rather than guessing. It stops earlier than the
+two-failure limit. TERM/INT/HUP stop owned supervisors; cleanup waits for them.
+
+Container and network names come from Compose's random recorded project. The
+project and service configuration have no fixed global names. Container event
+streams filter the exact project label; network streams match the exact project_
+name prefix. Both record create/destroy IDs and names, including --rm containers.
+An exit trap inventories names/labels, removes only exact-project objects with
+the approved cleanup helper, verifies emptiness and stops its own event streams.
+The driver's Docker inspection never reads Config.Env or credential contents, and never builds, pulls,
+retags or prunes. Missing resource-name evidence, an ended event stream, unknown
+ownership, leftover objects or quarantined lanes fail the proof. A SIGKILL cannot
+run an exit trap; durable wrapper receipts then require granted recovery.
+
+Run this as its own whole-slot phase. A still-running legacy landing.mjs gate or
+gate.sh is LEGACY BUSY, including a parent process. The driver does not suppress
+that refusal. The ordinary landing gate must exit before this proof phase starts.
+
+Planning runtime from sage-1837 is 12-15 minutes per wave, so reserve 60-75 minutes
+for all five waves, plus any separately granted image preparation. This is an
+estimate, not a measurement. Measured proof runtime is unavailable until this
+first run. Historical row 189 full gate was 659 seconds; the r4 focused 19-file
+run was 761.33 seconds and is not a full solo baseline. The resulting summary
+records actual per-gate times, pair makespans, slowdowns and total wall time.
+
+No image provenance receipt or combined integration SHA is available to Herb yet.
+The driver remains unexecuted. Sage will read the exact hashed driver and request
+Webby's static review before the landing/proof grant.
+
+Static node --check passed after sage-1839 single cleared. This is syntax-only;
+the driver has not run a proof or Docker command. Its runtime behavior awaits
+Sage and Webby review and the separately granted proof block.
+
+## Driver review fixes, sage-1857
+
+Webby's first review was CHANGES, B1, at bba870ee9. The revised driver takes
+tempRoot only from immutable start records for the plan's checkouts. After
+every owned gate exits, Docker cleanup and the final status/process checks
+run. The driver requires the exact short ga-/gb- scratch spelling, a matching
+lane, an owned real directory and no live owner, child group or process with
+the run paths in its argv before removal. It also requires a clean terminal
+receipt. A successful gate's root is removed recursively. A failed gate's
+root stays for diagnosis; an unverified cleanup also stays and fails the
+proof. docker-summary.json records removed, kept and error entries. Any
+cleanup error makes the driver fail. No unrelated scratch directory is read.
+
+Signal handlers are installed before configuration and preparation. Clone
+preparation is inside the try/finally, and yields between synchronous clones
+so a pending signal stops it before another invocation. A preparation signal
+writes failure evidence and reaches the cleanup path. Partial clones remain
+under runRoot as permitted by Sage; they are never confused with lane roots.
+SIGKILL cannot be trapped and still needs granted recovery.
+
+At 2026-10-21T08:26:41Z, Herb removed four earlier roots recorded in their
+own packet: ga-VPXhG7, gb-XeTAUS, ga-35Zo9Y and ga-R5IOT3. Each was an owned
+real directory with no process argv/cwd reference before removal. Names
+ga-AMtfI3 and ga-Vd9Ef2 were visible in the scratch directory listing but had
+no ownership evidence in Herb's packet; neither was opened or changed.
+
+## N4 read-only trace, pre-existing and out of scope
+
+Sage ruled in sage-1859 that N4 does not block 197. Legacy suites already
+reach Compose's read-only host auth mount, and the lane adds no exposure.
+Sage owns a DEFERRED entry for fixture PI_AUTH_FILE coverage. No fix is made
+in 197, and this procedure does not claim that the full gate is secret-free.
+
+At 9aa6d52d9:
+
+- gate-lane.mjs:109-111 keeps HOME real but neither keeps nor sets
+  PI_AUTH_FILE. compose.yaml:43 therefore selects its host auth-file default.
+- script-task is discovered by gate-lane.mjs:36. test-task.sh has no
+  PI_AUTH_FILE assignment. Calls at :149-150 (mock), :444, :460, :480, :483
+  and :520 (live) reach run-task. mosaic-task.mjs:321 copies the environment
+  and :395-400 invokes compose run mosaic-agent without changing that path.
+- script-release calls release activate at test-release.sh:69,85,93.
+  release.sh:41-54 health_check calls run-task with no PI_AUTH_FILE override,
+  then reaches the same Compose call. These tests use scratch MOSAIC_CONFIG;
+  that does not override the separate auth-file bind mount.
+- test-auth.sh:48-92 sets explicit fixtures, but calls auth.sh instead of
+  Compose. Package runs/task-cli.test.mjs exercises list/show, not run.
+
+This was a static source trace only. No auth file was opened, no credential
+value was read, and no Docker command, image build or proof was executed.
+
+
+## Proof4 watcher change (sage-2029, mos-1174)
+
+Proof3's eight gates passed and cleaned up, but Docker29 network events do
+not carry Compose project labels, so the driver's combined label filter
+missed their creation. Only this proof packet changes; none of the37
+c45ddeb6b candidate paths changes.
+
+Container events retain the label filter. Network events use a type filter
+and a local exact project_ name-prefix match, accepting default and other
+owned network names. The existing recorded-name project guard stays.
+The same exported watcher/parser powers unit tests, the proof and a daemon
+preflight before wave1. Importing the module does not execute a proof.
+Direct execution still installs signal handlers before preparation.
+
+The preflight creates one named and labelled mg197 probe network and one
+create-only container from the pinned imageId, --pull never, network none,
+no mounts or start. Exact-project label-checked cleanup removes both,
+including on failure. All four create/destroy observations must arrive
+within5000ms. Docker commands share that deadline; cleanup has a separate
+3000ms cap. Watcher shutdown is bounded. Failure prevents all gate waves.
+Probe metadata and outcomes go into docker-summary.json and summary.json.
+No Config.Env, credential file contents or raw foreign events are saved.
+
+Tests cover network events with name/type only, all project_ network names,
+foreign names/labels, recorded-name ownership, fragmented streams, early
+exit, missing create/destroy observations, deadline and cleanup failures.
+Sage-2034 accepted this scope. Grant sage-2035 supplied the runtime evidence below.
+
+## Granted verification, sage-2035
+
+On 2026-10-21, the whole events.test.mjs passed 8/0, with zero skipped or
+cancelled. node --check passed on run-proof.mjs and events.test.mjs. One
+exported probeDockerWatchers call used the supplied proof3 image ID and
+cleanupProject from the unchanged r8 launcher. No container was started;
+no pull, build, lane or wave ran. Both filtered post-probe Docker listings
+were empty, and the owned /proc cwd/project scan was empty. The slot was
+returned at 2026-10-21T15:16:52Z.

+Driver SHA-256:

-# Row 200: `stack-release.sh activate --sso` (Q175 phase 2 prerequisite)
-
-Launchpad, 2026-10-20. Author Launchpad, reviewer Webby, gate owner Sage. Issue #1698. Brief
-`docs/plans/2026-10-20_stack-release-sso.md` (blob 426336b177f6). Rulings sage-1389 (R1 uses the activation onto
-the current copy, plus a same-copy test and a latest-set mutant), sage-1403 and sage-1407 (N4), mos-1056 item 5
-(N4 is a window acceptance item), sage-1432 (round 2 for webby-0028 N1 and N2), sage-1556 (round 3: rebase onto row 190's
-landing 00d4cc1f6, and `--sso` for a named instance).
-
-Base 00d4cc1f6 since round 3 (`base.txt`), row 190's landing, which has row 192 (4429a104f) below it. Rounds 1
-and 2 were built on 4d487dfdc: aa1bd209e plus row 192's two commits picked. 48359dbfa is 83b32d8d8 (patch-id
-8d11f48a9e03) and 4d487dfdc is r2 37582e820 (patch-id 0e32af8aa2a4 on both). The webui tree at the base matches
-`launchpad/row192` at 37582e820 path for path. Rounds 1 and 2 are on `launchpad/row200`;
-round 3 is on `launchpad/row200-r3` (see Round 3 below).
-`candidate-manifest.sha256` lists its 3 paths; the packet files are not in it. Drift check at commit time:
-round 3, origin/refactor is 00d4cc1f6 itself, so `git log 00d4cc1f6..origin/refactor` is empty.
-
-No test touches `~/.mosaic-dev`, `~/.config/mosaic-dev`, `~/.mosaic`, a live unit or a live slot. T57 runs on
-the scratch roots and seeded pointers rows 187 and 189 use. Its config and slot sit in the test's temp dir,
-and the slot carries the `proofFile` read watch, so a run that opened it would fail the test.
-
-## Files
-
-| Path | Change |
-| --- | --- |
-| `scripts/stack-release.sh` | `--sso` on activate (usage, parse, `sso_for_target`), `sso_checks` and `slot_problem` (item 2), `sso_base` (rollback flags, item 3), `config_checks` (item 3 and N4), the `sso:` plan line and step lines. |
-| `packages/cli/tests/stack-release.test.mjs` | Fixture copies gain row 192's `--sso` marker, an old loader without `console`, and a C copy whose `ALGS` lack RS256. T57 (T56 before round 3), 11 subtests (2 in round 2, 1 in round 3). |
-| `docs/TOOLS.md` | Usage line and two paragraphs after row 189's `--no-send`. |
-
-## What it does
-
-1. **Item 1.** `activate ID BUSINESS --sso` drops `--public-host`, `--auth-header`, `--allow-user` and any proof
-   pair, and puts `--sso` after the other flags, before `--send` and `--tester-port`, as `webui-service.sh`
-   renders it (`sso_for_target`, `:775`). It may name the live copy once. After that, both a plain activate and
-   an `--sso` activate refuse `already-active`. Later activates carry `--sso` (`sso: carried`; T57 covers
-   activate, not `pm-on`, which carries the pointer's flags as it does for every flag).
-   `--plan` prints `sso: on; drops ...; carries ...`, plus the proof line's `dropped; --sso drops header ...`.
-   `--sso` with a pair, with `--no-proof` or on another verb is a usage error.
-2. **Item 2** (`sso_checks`, `:817`). These checks run whenever the run's Console flags hold `--sso`, before
-   anything stops:
-   - `sso-target`: the target's `cli.mjs` has no `--sso`.
-   - `sso-config`: the target copy's own `checkConsole` refuses `console`, or there is no `console.sso`. The
-     config is parsed in node, and only the message's first line is kept. A JSON parse error never quotes
-     the text.
-   - `sso-slot`: one per provider, from `lstat`, `stat` and `realpath` in `readSlot`'s order (`slot_problem`,
-     `:847`). The slot is never opened.
-3. **Item 3.**
-   - **Rollback** (`sso_base`, `:728`): from an `--sso` pointer to a copy without `--sso`, the Console flags
-     come from the rollback set of the activation that moved the stack onto the pointer's copy from the
-     target (`from_log arrival`). That set's `show-mosaic-webui.service.txt` is checked against its
-     `SHA256SUMS`. `--send` and `--tester-port` follow the pointer.
-   - **`sso-rollback-flags`** refuses when that set is missing, fails its sums, holds no readable argv, or
-     already ran `--sso`.
-   - **`config-console-key`** (`config_checks`, `:866`): any activate or rollback refuses before anything
-     stops when the config has a `console` key that the target's `scripts/mosaic-config.mjs validate` refuses.
-     The message says to remove the key first (restore step 1's backup), then run the verb again.
-4. **N4, the first half** (sage-1403, sage-1407). With no `console.sso` and the stack on another copy, the
-   `sso-config` refusal names the first step: "activate ID without --sso first, then write console.sso, then
-   run activate ID --sso". A copy before row 192 refuses the key, so the re-pin comes first. The `--sso`
-   activate is then the allowed same-copy re-pin.
-5. **TOOLS.md.** The flag, its refusals, the rollback rule and the N4 order.
-
-## Window plan acceptance item (N4, mos-1056 item 5, sage-1407)
-
-For the row 200 window plan, word for word:
-
- **Before the `console` key is written, the window re-pins to row 192 or later.** Check line, run before the
-  key is written: `git -C /mnt/storage/src/mosaic-stack merge-base --is-ancestor <row 192 landing sha>
-  <pointer copy sha from scripts/stack-release.sh status acme> && echo REPIN_OK`. It must print `REPIN_OK`.
-  If the window instead runs `activate <ID> acme --sso --plan` before the key is written, the
-  `refuses sso-config:` line must end with "activate <ID> without --sso first, then write console.sso, then run
-  activate <ID> --sso". It names that step only when the pointer is on another copy.
- **A rollback past row 192 removes the key first.** Check line, run before the rollback:
-  `scripts/stack-release.sh rollback acme --plan` must print no `refuses config-console-key:` line. If it
-  prints one, restore `config.json` from the window's step 1 backup and run the plan again. The rollback itself
-  refuses on the same check, so a skipped step stops it before anything stops.
- **Back-out line (webby-0028 N4, sage-1432).** Once a copy with `--sso` support is live, no verb turns `--sso`
-  off. Only a rollback to a copy before row 192 gets the preview set back, after the `console` key is removed
-  (the check line above).
-
-## Tests run (this worktree, final tree)
-
- `node --test --test-name-pattern='^T56' tests/stack-release.test.mjs`: 10/10 on the round 2 tree
-  (`/mnt/storage/scratch/launchpad-r200/t56-r2c.log`). Round 1 was 8/8 (`t56-6.log`).
- Round 3, this tree: `node --test tests/stack-release.test.mjs`, the whole file, 192/192
-  (`/mnt/storage/scratch/launchpad-r200/sr-whole-r3b.log`); T57 alone 11/11 (`t57-r3a.log`);
-  `tests/stack-instances.test.mjs` 23/23 (`si-r3.log`). No other test reads the 3 paths or pins their hashes.
- The cli suite and every `scripts/test-*.sh` go to Sage's gate.
-
-## Mutants (`mutants.py`, run as `python3 mutants.py <tree> [N ...]`, each against T57; T56 in rounds 1 and 2)
-
-| # | Mutant | Result |
-| --- | --- | --- |
-| 1 | no `sso-target` refusal (item 2) | KILLED |
-| 2 | no `sso-config` refusal (item 2) | KILLED |
-| 3 | no `sso-slot` refusal (item 2) | KILLED |
-| 4 | no `sso-rollback-flags` refusal (item 3) | KILLED |
-| 5 | no `config-console-key` refusal (item 3) | KILLED |
-| 6 | keep `--auth-header` under `--sso` (item 1) | KILLED |
-| 7 | keep `--public-host` under `--sso` (item 1) | KILLED |
-| 8 | rollback takes the latest activation onto the copy, not the arrival (sage-1389) | KILLED |
-| 9 | `sso-config` names no first step (N4) | KILLED |
-| 10 | `slot_problem` compares the unresolved `REPO` (round 2, N1) | not run, Sage's gate |
-| 11 | `proof_file_problem` compares the unresolved `REPO` (round 2, N1) | not run, Sage's gate |
-| 12 | `config_checks` passes a config that doesn't parse (round 2, N2) | not run; equivalent if it survives, guard kept (sage-1446) |
-| 13 | `sso_checks` reads the default config, not `MOSAIC_CONFIG` (round 3) | not run, Sage's gate |
-| 14 | `sso_base` reads `show-mosaic-webui.service.txt`, not the instance unit's (round 3) | not run, Sage's gate |
-
-9/9 killed (`/mnt/storage/scratch/launchpad-r200/mutants.log`). The script restored `stack-release.sh`, and it
-matches its pre-run sha256. No mutant hit the 300 s timeout. This batch ran without Sage's slot (sage-1414),
-while Darkwing's gate was running, so Sage reruns all 9 on the row 200 gate and doesn't take these results
-(sage-1423). Mutants 10 to 12 are new in round 2 and have not run. Sage runs 1 to 12 on the gate (sage-1446). Mutant 5's
-pattern now names the `holds` message, because the round 2 message also starts with `config-console-key "$cfg`.
-Every pattern matches once on the round 2 tree, and all 14 match once on the round 3 tree.
-
-## Choices
-
- **R1, `--send` and `--tester-port` follow the pointer.** These two flags come from the pointer, not from the
-  rollback set, so a `--no-send` or a tester port set after the arrival stays. This is row 189's rule that
-  rollback carries `--send` off. Tradeoff: the rolled-back Console differs from the set's unit in those two
-  flags, and the plan line says so.
- **`config_checks` runs for activate too**, not only rollback. An activate onto a pre-192 copy with the key
-  in place breaks that copy's loader the same way.
- **The inside-repository slot test** symlinks the secrets directory to a temp dir under the fixture repo. The
-  slot file is then not a link, but its real path is inside the repository.
-
-## Not tested
-
- The slot owner-uid refusal: it needs a file owned by another uid, which needs privilege.
-
-## Review r1 notes (webby-0028, non-blocking)
-
- **N1.** `slot_problem` (`:859`) and row 187's `proof_file_problem` (`:988`) compare a resolved path to
-  `REPO="$(pwd)"` (`:26`), which is not resolved. Run through the `~/src/mosaic-stack-dev-test` symlink, a slot
-  inside the repository passes here, and the Console refuses it after the stop. Confirmed by reading; Sage
-  rules on a round 2 or a follow-up.
- **N2.** `config_checks` (`:868`) returns 0 when config.json doesn't parse. Same ruling.
- **N3.** A check this script doesn't make: `slot_problem` refuses only a size of 0. A slot holding only a
-  newline, or two lines, passes here, and the Console's one-non-empty-line rule (`readSlot`) refuses it after
-  the stop. Reading the content would break the rule that this script never opens the slot.
- **N4, for the window's back-out step.** Once the live copy supports `--sso`, no verb turns `--sso` off on it.
-  The only way back to the preview set is a rollback to a copy before row 192, which removes the `console` key
-  first (the second check line above).
-
-## Round 2 (sage-1432: N1 and N2; N3 and N4 stay notes)
-
- **N1.** `slot_problem` (`:847`) and `proof_file_problem` (`:989`) now compare the slot's real path with
-  `realpath -m` of both `REPO` and `COPIES`, and refuse "cannot be resolved" if either fails. T57's
-  "round 2 (webby-0028 N1)" subtest runs the script through a symlink to the fixture repo
-  (`repo-link.200/scripts/stack-release.sh`). A proof file inside the repository is refused `proof-file-invalid`,
-  and a slot whose secrets directory links into the repository is refused `sso-slot` "is inside the repository
-  or the copies". Mutants 10 and 11 undo each check.
- **N2, with a deviation.** `config_checks` (`:867`) now tells "no key" (node exits 1) from "doesn't parse"
-  (exits 2) and refuses `config-console-key` "cannot be read as JSON" on the second. But webby-0028's case
-  doesn't reach it: `load_config` (common.sh, through `scripts/mosaic-config.mjs env`) exits 1 on a config that
-  doesn't parse, before anything is read or stopped. So the refusal is a guard for a config that changes after
-  `load_config` ran, and no test reaches it without a race. The T57 subtest "round 2 (webby-0028 N2)" checks
-  what does happen: activate, rollback and `activate --plan` each exit 1 with "common: configuration load
-  failed", the pointer, the start/stop log and the activation log are unchanged, and activate works after the
-  config is restored. Mutant 12 drops the guard and is expected to survive as equivalent for that reason. sage-1446:
-  the guard stays, and mutant 12 is equivalent if it survives, the same call as row 192's mutant 23.
- **N4.** The back-out line is in the window plan section above.
-
-## Round 3 (sage-1556: rebase onto 00d4cc1f6, `--sso` for a named instance)
-
- **Rebase.** Row 190 landed as 00d4cc1f6 and changed all 3 paths. The 5 round 1 and 2 commits are picked onto
-  it on a new branch, `launchpad/row200-r3` (no force-push, no branch delete, #426(a)). `launchpad/row200` stays
-  as it was. `docs/TOOLS.md` and the test file applied cleanly. `scripts/stack-release.sh` conflicted in `plan()`
-  and in the `--plan` lines of `do_activate` and `do_rollback`. The merge keeps both sides: the `sso:` plan line
-  comes before the Console line, the Console and CLI lines carry row 190's `$flags` (`--instance NAME`), and
-  `--plan` runs `ports_unclaimed` after `console_for_target` and before `plugin_checks` and `config_checks`.
-  Functions on this tree: `sso_base` `:738`, `sso_for_target` `:785`, `sso_checks` `:827`, `slot_problem`
-  `:857`, `config_checks` `:877`, `proof_file_problem` `:999`.
- **Named instance: no code change was needed.** Row 190's `instance_select` exports `MOSAIC_CONFIG` as NAME's
-  config, and the named Console unit sets `Environment=MOSAIC_CONFIG` to the same file. So `sso_checks` and
-  `config_checks` read `~/.config/mosaic-NAME/config.json`, and the slot path is
-  `~/.config/mosaic-NAME/secrets/mosaic-stack/<slot>`, the directory the Console's `readSlot` reads under that
-  unit. `sso_base` reads `show-$CONSOLE_UNIT.txt`, so a named rollback reads `show-mosaic-webui-NAME.service.txt`
-  from NAME's own set. The pointer, the log and the sets are in NAME's data root. One comment (`:734`) named the
-  default unit's file and now says `show-$CONSOLE_UNIT.txt`.
- **Test.** New T57 subtest "round 3 (sage-1556)": instance `alpha`. A missing slot refuses `sso-slot` and names
-  alpha's slot path. `--plan` prints `--instance alpha` on the Console line. `activate C1 acme --sso` writes
-  `--sso` to `mosaic-webui-alpha.service` (with `MOSAIC_CONFIG` set to alpha's config), leaves the default
-  Console unit unwritten, and status matches. After the key is removed, `rollback` takes its flags from alpha's
-  arrival set, `show-mosaic-webui-alpha.service.txt`. The slot carries the read watch. Mutants 13 and 14 undo
-  the two instance-specific reads.
- **Rename.** Row 190 also named its test T56, so this row's test is now T57; `mutants.py` runs `^T57`, and the
-  in-repository temp dirs are `t57-slot-` and `t57-proof-`.
- **Defect from round 1, fixed.** Round 1 added `| --sso` to the activate usage line, but T53 test 6 (row 187)
-  and T55 test 5 (row 189) still matched the old line, so 4 tests failed (2 subtests and their parents). Rounds
-  1 and 2 ran only this row's test, so the failure went unseen. The round 2 tree d4ec998cc fails the same 4
-  (`r2-t53t55.log`), and the first whole-file run on this tree was 188/192 (`sr-whole-r3.log`). Both regexes now
-  include `| --sso` (`:1672`, `:1831`; T57's own check is `:1940`). Webby: please check these two lines; the
-  round 2 approve did not cover them (sage-1569). A grep of `packages/*/tests` and `scripts/test-*.sh` for the
-  usage text (`--no-proof]`, `proof-file PATH`, `usage: stack-release`) finds no third copy, and finds no
-  64-hex pin on any of the 3 paths. The only test files that name `stack-release` are `stack-release.test.mjs`
-  and `stack-instances.test.mjs` (a comment); both ran as whole files (above).
- **Not changed (note).** The N4 first step reads "activate ID without --sso first"; for a named instance the
-  operator also passes `--instance NAME`, as with every verb. The message doesn't repeat it.
-
-## Not done here

- No change to the live pointer, units or config. The phase 2 window is Sage's and Mos's.

+# Row 199 (#1697): per-agent credential store, each agent's own git identity, publish to its fork
+
+Builder: Megavolt. Brief: `docs/plans/2026-10-20_agent-credentials.md`. Design: `DESIGN.md` r6 at
+4d3007ec9, approved by Duckworth in duckworth-0027 (REVIEW-r6.md at 640011518). Authority model ruled
+by Mos in mos-1027. Branch: megavolt/row199. Reviewer: Duckworth.
+
+Status: candidate on megavolt/row199-on-190, rebased on origin/refactor 00d4cc1f6 (sage-1555). The
+full gate and the section 11 mutants ran in Sage's slot; results under "Runs".
+
+## Commits so far
+
+- 286bf598c business: agent identity, the publish grant, the project upstream with the D9c parse, store
+  credential references; git.push.remote as a hard wait.
+- a2c387dba bus: broker publish authority (checkPublish, recordPublish, publishRefused, pushCommit on
+  the raise); the D9c parse moves to `business/src/vocabulary.mjs`; pm.md and chief-of-staff.md list
+  git.push.remote among the hard waits.
+- 609dc9364 bus: the per-agent credential store in `credentials.mjs`.
+- 504336797 bus: runtime wiring, the store root and the four publish entries in the op table.
+- a18fc6cf8 tasks: request calls use `useFor` keyed from the session; the start probe keeps `use`. The
+  D5 test in `credential-store.test.mjs` pins the `use(` call sites to `credentials.mjs` (useFor's own
+  call) and `tasks/src/adapter.mjs` (the host's @sync and start probe).
+- aa740cc71 bus: the lifecycle verbs `credentials.issue`, `credentials.revoke` and `credentials.delete`
+  in `credential-verbs.mjs`, the broker branch, the runtime wiring; `organizationWriter` gets a
+  `detail` on `write` and a receipt-only `record`.
+- 0cdace415 cli: `mosaic credentials status|issue|rotate|revoke|delete`, the scripts/mosaic route, docs.
+
+## Deviations from DESIGN.md r6
+
+1. **Identity is optional on an agent.** D8 reads as identity on every agent. Today's business files
+   carry none, so identity stays optional and `publish` requires it (N10's load refusal). An agent
+   without identity commits as E7 (T6).
+2. **Revoke of a `{file}` or `{env}` reference.** Section 6 describes revoke for store references.
+   For a reference outside the store, revoke forgets the token in memory and never unlinks the file;
+   the lifecycle verb then turns the business file's reference into `store`, so a restart finds
+   nothing. The test: `credential-store.test.mjs`, "revoke of a {file} reference".
+3. **Issue order.** Issue writes the token file (tmp, fsync, rename, dir fsync), then runs the
+   caller's commit (the business file's reference becomes `store`), then sets memory. A failed commit
+   leaves the file on disk and the token out of memory, so the agent stays `not-issued` until the
+   issue is run again. The test: "a failed commit leaves the token on disk but not in memory".
+4. **The D9c parse lives in `business/src/vocabulary.mjs`, not `business.mjs`.** The broker reads
+   `forkProblem` and `forkUrl`, and `project-runtime.test.mjs` pins the broker's import closure to
+   files that import nothing. `business.mjs` wraps `parseGiteaUrl` with the loader's refusal
+   messages. The pin test names the two new imports.
+5. **`withGitea` takes the publish ticket, not a cap (D9b).** The key is the session checkPublish
+   checked with `#agent` (a run holding its claim; never a tester, reader or human), read through
+   `broker.publishSession(ticket)`. The token is usable only between checkPublish and recordPublish
+   or publishRefused. Its refusals are filed once, by publishRefused on the task's trail, and not
+   also by `refusing()`. The test: `publish.test.mjs`, "runtime: withGitea keys from the open ticket
+   only".
+6. **Role contracts.** `workflow-roles.test.mjs` requires the hard waits listed in `roles/pm.md` and
+   `roles/chief-of-staff.md` to equal GATED_ONLY. Adding git.push.remote to the vocabulary made it
+   fail, so both lists now name git.push.remote. Prose only; no hash pin reads either file. Duckworth
+   should review this hunk because `roles/` is reviewed authority.
+
+7. **Delete takes a reason.** Section 6 lists `delete AGENT` with no reason. The broker requires
+   `reason` on delete as on revoke, so every receipt that ends a credential says why.
+8. **Rotate is `credentials.issue`.** There are three bus verbs, not four. An issue over an entry the
+   bus holds is recorded as `rotate` in the receipt and the answer. The CLI's `rotate` reads the
+   status first and refuses before reading stdin when nothing is issued.
+9. **Issue covers entries the bus loaded.** The business file must already name the kind for the
+   agent, and the bus must have loaded that reference at start; otherwise `credential-unknown`. An
+   agent added after the bus started needs the restart row 165 already asks for. Row 194's human
+   `create` is where a new agent's `store` references come from.
+10. **No Console page yet.** Section 6 puts the verbs in the Console's agent page too. This branch has
+    the bus verbs and the CLI. The Console page is a separate piece (packages/webui, its `BUS_VERBS`
+    and `STATUS` pins); I raise the split with Sage before the manifest. Ruled in sage-1421: the
+    Console page is out of row 199 and becomes a follow-up row with Webby as reviewer. The manifest
+    holds bus, business, tasks, cli and seat.
+11. **The push runs in the bus child, and the git socket polls for it (D9b).** The git socket runs in
+    the host process. The broker, the runtime and the token are in the bus child that
+    `packages/cli/src/host.mjs` forks, and host ops cross that IPC one at a time with a 10 s answer
+    limit. ls-remote and the push can run longer than that, so `withGitea(ticket, fn)` can't wrap a
+    host-side git. The split: the socket runs D9 steps 3 and 4 (tip and identity under the lock,
+    `working.publish`), then op `publishPush`, which starts `publishRemote` in the bus child under
+    `withGitea` and answers `{state: 'running'}`. The socket polls op `publishResult` every 200 ms
+    until it reads `pushed` or `refused`. Fork, user, source and destination come from the ticket
+    (`broker.publishTarget`), never from the host's message. `recordPublish` also refuses `ref-moved`
+    when the pushed ref isn't the ticket's destination. A second `publishPush` on a running ticket
+    refuses `publish-busy`. The token reaches git on fd 3 only (`runGit` option `pass`), read once
+    by a one-shot credential helper that answers `get` for https on the fork's exact host and port.
+    On close, a running publish's git isn't awaited; git's own time limit ends it, and the ticket
+    goes with the process. The 10 s IPC limit stays as it is (sage-1440). The poll has a bound
+    (sage-1440): `publishDeadlineMs`, by default four times git's limit and grace (publishRemote runs
+    at most four git commands) plus 30 s. Past it the socket refuses `publish-timeout`, filed once by
+    publishRefused, and logs that the bus process's push may still reach the fork. A failure that is not a refusal is filed as `git-failed` and logged on
+    the bus's stderr by error name and code only. Tests: `seat/tests/publish.test.mjs` (11),
+    `bus/tests/publish.test.mjs` (the process ops), `cli/tests/publish-socket.test.mjs` (7, end to
+    end through the socket, the in-process runtime, the store and a TLS fake Gitea; one is the
+    publish-timeout outcome).
+12. **No harness tool for publish.** `packages/harness/src/git-tools.mjs` has push, fetch and land
+    clients. A runner tool that calls the socket's `publish` op is in packages/harness, outside the
+    manifest scope sage-1421 set. Today a publish needs a socket client; the tool is a follow-up.
+13. **The bind rule's `git.push.remote` clause has no test of its own.** D11 adds it and the
+    launcher has it. A role can publish only a push its own role made (`work-not-yours`), and
+    `recordPush` needs `git.push.working`, which already binds the socket. No role reaches the
+    clause alone, so dropping it changes no outcome today. It matters once a role can publish work
+    it didn't push. Ruled in sage-1440: keep it; its mutant goes in the section 11 list as
+    equivalent, with this reasoning, and Duckworth judges it.
+14. **A push between checkPublish and the git push refuses; it never lands a different commit.**
+    T3 says such a push "doesn't change the commit that lands". Under the hard wait it refuses:
+    `working.publish` checks the work ref's tip against the ticket's source under the lock
+    (`ref-moved`, `seat/tests/publish.test.mjs`), and `recordPublish` checks `pushCommit` again
+    (`decision-mismatch`, `bus/tests/publish.test.mjs` "r4 B4"). The fork gets only the ticket's
+    oid either way. N9's routing-commit test still applies. Ruled in sage-1440: T3's wording in
+    DESIGN.md now reads "refuses with `ref-moved` or `decision-mismatch`", and an end-to-end test
+    asserts each code mid-flight in `cli/tests/publish-socket.test.mjs`: a push after checkPublish
+    refuses `ref-moved` with no request to the fork; a push recorded while the bus process pushes
+    refuses `decision-mismatch`, filed once, and the fork holds only the ticket's oid.
+
+15. **Fix: rotate on a due gitea key (gizmoduck-0050, sage-1494).** The CLI's `ISSUED` set
+    (`packages/cli/src/credentials.mjs`) listed valid, expiring and expired, but the bus's `status()`
+    gives a gitea key past its rotate-by date `rotation-due`. So `credentials rotate` refused the one
+    case it exists for. `ISSUED` now names every state status() gives a held token. The test:
+    `cli/tests/credentials.test.mjs`, "rotate goes ahead on each held state". Its mutant (the old set)
+    fails that test and goes in the section 11 list.
+
+16. **The bus process refuses a boot config carrying `publishTls` (M26, sage-1563).** process.mjs
+    used to drop `publishTls` from the boot config before `startBroker`, and no test could see the
+    drop. The host's boot config (`packages/cli/src/config.mjs`) never carries it; it is the tests'
+    scratch CA for an in-process runtime only. A boot that carries it now refuses
+    `invalid-host-request` and the process exits 2, rather than trusting it or dropping it quietly.
+    The test: `bus/tests/publish.test.mjs`, "the bus process answers the publish ops from their own
+    lines". Every test file that reads process.mjs ran singly, green (see "Runs").
+17. **M17 is equivalent: `#authorityFor`'s pushCommit comparison is also made by `#publishFacts`.**
+    A git.push.remote raise with no recorded push refuses `no-push` (`broker.mjs` raise,
+    `pushCommit = ... ?? fail('no-push')`), so every publish decision carries a pushCommit.
+    `#publishFacts` takes `source = result.pushCommit` and refuses `decision-mismatch` when it isn't
+    `#latestPush(task_ref).commit`, the same two values `#authorityFor` compares. The check stays as
+    defense in depth, for a decision whose context lacks pushCommit, which no code path writes today.
+    Duckworth judges it, as with M27.
+
+## N9, for the routing commit (sage-1388)
+
+Today git.push.remote is a hard wait, so every publish carries a decision, and the decision's
+`pushCommit` fixes the commit. If a later commit routes git.push.remote within role, a publish has
+no decision and no `pushCommit`. `#publishFacts` then takes the commit from `#latestPush`, and the
+git socket's tip check under the lock is the only thing that holds it. That commit needs a test
+that a push between checkPublish and the git push doesn't change what lands.
+
+## R1, the backup set
+
+Checked at 504336797. Row 185's `backup_store` (`scripts/stack-release.sh:372-392`) copies only
+`<dataRoot>/bus/bus.sqlite`, plus its sums, modes, listing and stamps, into
+`<dataRoot>/backups/stack/<activation>/`. Nothing under `<configDir>` is copied, so
+`<configDir>/secrets/agents` isn't in the backup set. `rehearse` copies the live business file
+through `R_BUSINESS_JS` (`:1268-1288`). Its `swap` replaces every credential reference, a `store`
+one included, with a placeholder file in the rehearsal's own dir. The guard then refuses
+`credential-ref-live` unless every reference is such a placeholder (`:1329-1337`), so a rehearsal
+never reads a store token. A backup tool outside this repository that copies `<configDir>` would
+copy tokens. That is R1's open half, and it is Jason's to check on each VM.
+
+## T1 limit
+
+A wrong owner on a store dir or file can't be set up without root, so T1 covers modes, symlinks and
+dirs. The owner check (`st.uid !== process.getuid()`) is in `privateDir` and `#read`, and is untested.

+# Row 199 design: a credential store per agent, own git identity, pushes to a remote
+
+Megavolt, 2026-10-20. Gitea #1697, MVP T1 item 6. Brief: `docs/plans/2026-10-20_agent-credentials.md`.
+Reviewer Duckworth. Mos rules on the authority model (section 9) before any code. Base: refactor at 992650232.
+No credential value was read to write this. Evidence is code and docs only.
+

+and N7 in D9a, N8 in D9 step 1.
+
+r5 takes webby-0011 N1 (row 194 review, through honker-0009): the host checks at each push that the
+remote's owner is the agent's own Gitea user. r4 named one `remote` per project, which can't be a fork per
+agent (O1) once two agents publish the same project. So `projects.<p>.remote` now names the upstream
+repository, and the host builds each agent's fork URL from it (D9 step 2, D10, T3). It also fixes a conflict
+found while building: D8 made `identity` required for every agent whose definition declares `gitea`, while D9
+step 2 says today's files load unchanged. Coder declares `gitea`, so r5 makes `identity` optional and
+`publish` require it (D8).
+
+r6 answers duckworth-0026 (REVIEW-r5.md at 3cb6888e1), with Mos's acceptance (mos-1043). B5: the derived URL
+has one name, `fork`, and D9a's `ls-remote`, step 5's push, the helper's host match, `checkPublish`'s result
+and step 6's event all use it (D9, D9a, D9b, T3). B6: the URL parse is written down (D9c) and tested (T3).
+N10 in D8 and T3. N11 in D9a and A3. N9 is carried to BUILD.md for the routing commit.

+## 0. Terms
+
+- **Stack instance**: one Mosaic Stack deployment (row 190). It has one OS user, one config dir
+  `~/.config/mosaic-NAME` (here `<configDir>`), one data root and one bus. Case 1 and Case 2 are two stack
+  instances on two VMs (DECISIONS Q180).
+- **Agent**: a role instance in a business file (`roles.<agent>`). Today's code calls it "instance". This
+  design says agent.
+- **Kind**: a credential type: `gitea`, `vikunja`, `model`.
+- **Host**: the bus process and its git socket, running as the stack instance's OS user, outside any sandbox.
+
+## 1. What exists (measured at 992650232)
+
+| Code | Fact | Where |
+|---|---|---|
+| E1 | The business file references credentials per agent: `roles.<agent>.credentials.<kind> = {file or env, rotateBy or expires}`. The kinds an agent may hold are the ones its role definition lists | `business/src/business.mjs:89-111`, `credentials.mjs:18-38`, `role.mjs:105-118` |
+| E2 | The bus reads each token once at start (O_NOFOLLOW, own uid, 0600, at most 16 KiB, outside the repos and data root) into a private map keyed `<business>/<agent>:<kind>` | `bus/src/credentials.mjs:18-89`, `bus/src/runtime.mjs:78-89` |
+| E3 | Only Vikunja uses a token: `credentials.use("<business>/<agent>", "vikunja", ...)`. Gitea tokens are loaded and never used. `assertClean` refuses any event that contains a token | `tasks/src/adapter.mjs:70`, `runtime.mjs:134`, `broker.mjs:560` |
+| E4 | Agents run in bwrap as the bus's own uid. `~/.config`, `~/.mosaic` and `~/.ssh` are not bound. The git socket is bound only for `git.push.working`, `review.verdict` or a landing | `seat/src/sandbox.mjs:21-30, 104-124`, `cli/src/launcher.mjs:401` |
+| E5 | A session proves who it is with a 64-hex cap the broker mints and maps to a frozen session record. The git socket resolves the cap to (business, role) before anything else | `broker.mjs:280, 379-383`, `packages/cli/src/git-socket.mjs:398-407` |
+| E6 | The model credential is one env file per host (`EnvironmentFile=-%h/.config/mosaic-dev/secrets/claude-session.env`). `ENV_ALLOW` passes it into every sandbox, so every agent holds the same model token | `cli/systemd/mosaic-bus.service.in:24`, `seat/src/session.mjs:83-94` |
+| E7 | Commits in a session's clone use `<agent>@<business>.mosaic.invalid`. Landed squashes use "Mosaic bus host" | `sandbox.mjs:151-157`, `working.mjs:280-281` |
+| E8 | No code pushes to a remote. The git socket pushes bundles into a local bare working repo with no remote and no credential | `working.mjs:1-14, 198-238` |
+| E9 | Adding or changing an agent refuses a definition that declares credentials (`organization-credentials-out-of-scope`). Binding them is a hand edit. Row 194's design keeps that refusal for create and hire "until the credentials row" | `business/src/instance-settings.mjs:20-29`, row 194 DESIGN.md D1 |
+| E10 | The development repository's helper pushes as one identity from one JSON file | `scripts/git-credential-mosaic.mjs` |
+
+So per-agent references and a host-only reader already exist for two kinds. What's missing: a fixed place for
+the files, an agent identity, any remote push, lifecycle verbs, and a model credential that agents don't
+share.
+
+## 2. The store (brief item 1)
+
+D1. **Layout.** Each stack instance keeps its agents' secrets under its own config dir:
+
+```
+<configDir>/secrets/agents/                       0700, owner = the stack instance's OS user
+<configDir>/secrets/agents/<business>/<agent>/    0700
+<configDir>/secrets/agents/<business>/<agent>/<kind>   0600, the token only, one line
+```
+
+This is row 190's secrets root (`<configDir>/secrets/...`, as Q175's slot uses). The token file keeps E2's
+format, so the bus reader doesn't change. Nothing in a token file is a name, an email or a URL. Those are not
+secret and go in the business file (D6), where review sees them.
+
+D2. **The business file reference.** A new reference form, `{"store": true, "rotateBy" | "expires": DATE}`,
+means "the file at the layout path for this business, agent and kind". The path is derived, never written,
+so an agent's entry can't name another agent's file. The old `{file}` and `{env}` forms stay valid for
+migration (section 7). A `{file}` reference that points inside `<configDir>/secrets/agents/` but not at its
+own agent's path refuses `credential-not-yours` when the business file loads.
+
+D3. **Read path.** Unchanged in shape: the bus reads every entry once at start (E2) and on a store change
+(section 6), and holds the values in memory. No sandbox binds `<configDir>` (E4 already holds). No token goes
+into a sandbox for `gitea` or `vikunja`. The agent asks the bus to act, and the bus uses the token.
+
+D3a. **A `store` reference with no file.** ENOENT on a `store` path loads as an absent entry. `status` shows
+`not-issued`, and `useFor` refuses `credential-unavailable`. The bus still starts. This is the state after a
+create without `issue` (D13) and after `revoke` (section 6). Every other defect still refuses start: wrong
+owner or mode on the file or a dir, a symlink, a non-regular file, bad format, a missing or wrong-mode
+`secrets/agents/` dir. `{file}` and `{env}` keep E2's behavior, where a missing file refuses start.
+
+## 3. The "RLS equivalent" (brief item 1)
+
+Three layers. Each one is enforced by code or the OS, not by prose.
+
+D4. **OS, between stack instances.** Files are 0600 and dirs 0700, owned by the stack instance's own OS user.
+Case 1's user can't read Case 2's store (Q180: each instance under its own user without sudo). The bus refuses
+to start when any file or dir under `secrets/agents/` has the wrong owner or mode (`credential-file`, as E2
+does for files today, extended to the dirs).
+
+D5. **Bus, between agents of one stack instance.** The principal for every credential use comes only from the
+verified cap (E5). The agent-facing API is `credentials.useFor(session, kind, op)`: `session` is the broker's
+frozen record, and the key is built from `session.business` and `session.role`. It has no agent argument, so
+there is nothing in a request to point at another agent. The existing `use(name, kind, op)` stays for the
+host's own `@sync` entry and is not reachable from a request. The tasks adapter's per-role calls (`ctx.as`,
+`verbs.mjs:126`) move to `useFor`. Any request field that names an agent other than the caller (`as`,
+`agent`, `instance`, `role` on a credential path) is refused `credential-not-yours` and recorded through
+`broker.refuse()` as `action.refused`, with the caller's cap and the task ref. A build test greps every
+`credentials.use(` call site and fails on a new one outside the allowlist.
+
+D6. **What stays open.** A process of the same OS user outside the sandbox can read every agent's file. That
+is the same limit as the human proof (P19 333). Q180's per-user VMs move the boundary to "one stack instance
+per OS user". Agents of one instance are kept apart by the sandbox and D5, not by the OS.
+
+## 4. Kinds (brief item 2)
+
+| Kind | 10-27 | Use |
+|---|---|---|
+| `gitea` | yes | Git push to a granted remote (section 5). Gitea API verbs (issues, pull requests) wait. The factory's review flow runs in the working repo today, and no 10-27 case needs an agent to open a pull request |
+| `vikunja` | yes, exists | Moves to `store` references and `useFor`. No behavior change |
+| `model` | per stack instance only | See D7 |
+
+D7. **Model provider.** A model token has to sit inside the sandbox today, because the harness calls the
+provider itself (E6). Per-agent model tokens need a proxy that holds the real token and gives each run its own
+short-lived one, which is the CLIProxyAPI line in TARGET.md. That waits for its own row. For 10-27 the model
+credential is per stack instance: row 190's `<configDir>/secrets/claude-session.env`, owned by that
+instance's OS user. It is never a copy of jwoltje's file. Jason signs in on each VM user himself (A6). Whether
+Case 1 and Case 2 run on Jason's existing subscription or need a new account is Jason's call (Q-J1). This row
+doesn't pick. A pi model credential also waits for P19 #383.
+
+## 5. Git identity and push (brief item 3)
+
+D8. **Identity.** A new business-file key, `roles.<agent>.identity = {name, email, gitea: {url, user}}`. It is
+optional, because today's business files with a `gitea` agent (coder) must load unchanged. `publish` (D9
+step 2) requires it, and requires that the definition declare `gitea`. A business file with a `publish`
+grant on an agent that lacks either refuses at load, and the error names `roles.<agent>.publish` and says
+"needs identity and a gitea definition" (N10). Load is the only place this is checked: a business file that
+fails it never reaches the bus. The sandbox sets `GIT_AUTHOR_*` and `GIT_COMMITTER_*` from
+it in place of E7's invalid domain. The email is the one Jason gives the agent's Gitea user, so Gitea links the
+commits to that user. Agents without `gitea` keep E7.
+
+D9. **Push to a remote: a new git socket op, `publish`.** No new socket, no bundle, and no token in the sandbox.
+
+```
+publish {"cap", "op": "publish", "task_ref", "project", "branch", "decision"}
+  -> {"ok": true, "result": {"fork", "ref", "commit", "previous"}} or a refusal
+```
+
+The host checks, in order, and each refusal goes through `broker.refuse()`:
+
+1. Identity from the cap (E5), then the broker's `#checkAuthority(s, "git.push.remote", {decision, target:
+   task_ref})`, as `checkLand` does for a merge (`broker.mjs:907-913`). `git.push.remote` is a new action in
+   ACTIONS and is not in ROUTED (REQ-WAIT-3, `packages/business/src/vocabulary.mjs:52-58`,
+   `broker.mjs:42-69`), so it is a hard wait and classifies `gated` for every role. Every publish therefore
+   needs a decision the human resolved for this task ref. A decision is spent once (`decision-consumed`).
+
+   **The decision binds one commit.** `#authorityFor` binds action, role, thread and target only
+   (`broker.mjs:769-798`), so the commit needs its own carrier. The raise records it the same way it records
+   `holderRun` for `role.revoke` (`broker.mjs:1733`). When the action is `git.push.remote`, the
+   `decision.raise` event body gets `pushCommit`. That is the commit of `#latestPush(business, target)` at
+   raise time, read by the broker and never taken from the agent. A raise with no recorded push for the task
+   refuses `no-push`. The decision's question shown to the human ends with that commit. `#authorityFor` then
+   refuses `decision-mismatch` when `context.pushCommit` differs from the commit of `#latestPush` now, which
+   is the same check `holderRun` gets at `broker.mjs:796`. So the sequence approve at A, push B, publish B
+   refuses.
+   No role definition grants the action yet. When Jason's PRD version routes it (Sage, Vikunja #420), a
+   reviewed commit adds it to both ROUTED lists and to coder's `withinRole`. From then on a coder publishes
+   without a decision, and `decision` is optional for a within-role class only.
+2. The project is in the agent's grant, `roles.<agent>.publish: [project]`, and the business file names the
+   project's upstream repository, `projects.<project>.remote: "https://HOST/OWNER/REPO"`
+   (`remote-not-granted`). Both URLs pass D9c's parse at load. The upstream's host and port equal
+   `identity.gitea.url`'s (`remote-host-mismatch`). The host never contacts that URL. It builds the agent's
+   fork, `fork = https://HOST[:PORT]/<gitea.user>/REPO`, from the upstream's origin and repository name and
+   the agent's own `gitea.user`. `fork` is the only URL the rest of `publish` uses: D9a's `ls-remote`, step
+   5's push, the helper's host match, `checkPublish`'s result and step 6's event. So the owner of the
+   repository that receives a push is the agent's own Gitea user on every push, by construction, and the
+   agent can't name it (webby-0011 N1). D9c is what makes "by construction" hold. Gitea's refusal of a
+   push to a repository the user doesn't own or collaborate on is the second layer. An upstream whose owner
+   equals the agent's `gitea.user`, compared without case, refuses `remote-not-fork`, at load and at push. `remote` is a new key
+   beside `root` and `repo` (`business.mjs:186`), and `identity` and `publish` are new keys on a role entry
+   (`business.mjs:89`). All three are optional, so today's business files load unchanged.
+3. The source is one commit, `C = context.pushCommit`. It is checked three ways, so all three are equal:
+   the decision's commit, the commit of `#latestPush`, and the work ref's tip in the working repo,
+   `work/vikunja-<project>-<task>` (`working.mjs:110-114`). The tip is read under the repository's lock, and
+   if they differ the push refuses `ref-moved`. The work ref is per task, not per agent. Two checks make it the
+   caller's: `#latestPush` was recorded by the caller's role (`work-not-yours`), and step 4. The destination is always `refs/heads/<gitea.user>/<branch>`, built by the host.
+   `validBranch(branch)` holds (`invalid-request`). The agent never names the destination ref.
+4. Every commit in `main..<work ref>` has author and committer email equal to `identity.email`
+   (`identity-mismatch`).
+5. The push runs through `credentials.useFor(session, "gitea", ...)`: `git push <fork> <C>:<dst>`, by oid,
+   with no `+` and no `--force`. It never pushes by ref name, so a push to the working repo after
+   `checkPublish` can't change what goes out (`non-fast-forward` from git stays a refusal). Git runs with E8's SAFE flags
+   (`working.mjs:92-98`), which set `protocol.allow=never`. `publish` adds exactly two flags,
+   `protocol.https.allow=always` and `http.followRedirects=false`, plus `GIT_TERMINAL_PROMPT=0` and no global
+   or system config. The token reaches git through a one-shot credential helper that reads it from an
+   inherited pipe, never through argv, env, the URL or a file. Seat `gitEnv` (`checkout.mjs:79-89`) takes only
+   PATH from the host and sets the rest itself, so no proxy or `GIT_SSL_*` variable reaches git. `publish` takes a `tls` parameter that
+   defaults to `[]`, the same way `push` takes `fsck = FSCK` (`working.mjs:100`). Tests pass
+   `["-c", "http.sslCAInfo=<scratch CA>"]`. The host never sets it, and nothing in config or env reaches it. The helper answers `get` only when `protocol`
+   is `https` and `host`, port included, equals `fork`'s. It writes nothing for any other `get` and for
+   `store` and `erase`. `assertClean` checks git's output, so a fork that echoes the token gets
+   `credential-leak`.
+6. The bus records `action.allowed` for `git.push.remote` with fork, ref and commit.
+
+D9a. **The agent's fork must share root's history.** A push sends every object the fork lacks. The working
+repo's `main` is the project root's history (`working.mjs`, seed), so a fork that doesn't share it would
+receive all of root, landing squashes included. The check runs on `fork`, never on the upstream: a related
+upstream says nothing about what the agent's `<user>/REPO` holds.
+`publish` runs `seed` first (`working.mjs:164-176`), under the repository's lock as `push` does, so `main`
+catches up with root before the check below. That means a fork also receives any landed root commits that
+upstream doesn't have yet, because they sit under the agent's work. That is expected: the agent's branch is
+built on them.
+Before the push, the host runs `git ls-remote --symref <fork> HEAD` (same flags and helper). It refuses
+`remote-unrelated` when the fork is empty or when that tip isn't a commit the working repo already has and an
+ancestor of `main`. When `ls-remote` exits non-zero, for a fork that doesn't exist, a refused token or a
+network failure, `publish` refuses `fork-unavailable` and the push doesn't run (N11). Git's stderr isn't
+parsed to tell those apart and isn't returned, since it can carry the URL. Only `ls-remote` crosses the
+network for this, so nothing is fetched from the fork. If the fork has moved past root, the refusal stands
+until root catches up. That is a human pull into root, not an agent's.
+
+D9c. **The URL parse (B6).** `projects.<p>.remote` and `identity.gitea.url` are parsed with `new URL()` at load,
+and the business file refuses to load unless all of these hold:
+
+- The scheme is `https:`. There is no username, password, query or fragment.
+- The string equals its own normalized form: for the upstream, `url.origin + url.pathname`; for
+  `gitea.url`, `url.origin + "/"` or `url.origin`. So a dot segment (`/<user>/../OWNER/REPO`), a
+  percent-encoded dot, an upper-case host, an explicit `:443`, a backslash, userinfo, a query and a fragment
+  each refuse, because `new URL()` would change them (checked with node: each differs from its normalized
+  form). A trailing slash survives normalization and is refused by the two-segment rule below. The checks below run on that path, so the owner that is checked is
+  the owner that is used.
+- The upstream's path is exactly `/OWNER/REPO`: two non-empty segments, no more and no fewer. One trailing `.git` on
+  REPO is allowed and stripped. `fork` is built from the stripped REPO.
+- `OWNER`, `REPO` and `gitea.user` each match Gitea's name rule, `^[A-Za-z0-9_.-]{1,100}$` and not `.` or
+  `..`. REPO after stripping must still match.
+- `gitea.url`'s path is `/`. A Gitea served under a sub-path isn't supported by this row and refuses at load.
+- Host and port are compared after `new URL()` normalized them, and an omitted port counts as 443 on both
+  sides.
+- Gitea compares user and repository names without case (`lower_name`), so `remote-not-fork` compares the
+  upstream's OWNER with `gitea.user` without case. An upstream owned by `Coder` and a `gitea.user` of `coder`
+  would otherwise build a "fork" that is the upstream itself.
+
+D9b. **How `publish` reaches the broker and the store.** The git socket runs in the bus process
+(`cli.mjs:504-506`) and reaches the broker only through the host's op table (`bus/src/runtime.mjs:222-246`).
+`publish` adds three entries there, each wrapped in `refusing()`:
+
+- `checkPublish(cap, args)`: steps 1 to 3, including the decision check. It returns `{ticket, fork, user,
+  email, source}` and no token. The ticket holds the session and the decision until `recordPublish`, the
+  same way `checkLand` holds a landing.
+- `withGitea(cap, fn)`: `credentials.useFor(broker.session(cap), "gitea", fn)`. `fn` gets the token and runs
+  step 5. The token never leaves that call.
+- `recordPublish(ticket, result)`: step 6, and it spends the decision.
+
+The op table gets no entry that returns a token.
+
+D10. **Which refs.** Our side: only `refs/heads/<gitea.user>/*`, set by the host (D9 step 3). The default
+branch and other agents' prefixes can't be named. Gitea side, two options (Q-M1):
+
+- **O1. A fork per agent. Ruled by Mos (mos-1027).** The agent's Gitea user has read on the upstream repo and owns a fork
+  named like it. The host derives the fork's URL from the upstream and the agent's user (D9 step 2).
+  Its token can write only repos the user owns or collaborates on, so Gitea itself stops any push to upstream
+  or to another agent's fork. No branch rules are needed per agent, so none can drift. The cost: work reaches
+  upstream as a pull request from the fork, opened by a human or a later API verb.
+- **O2. One shared repo. Not chosen.** The agent is a Write collaborator. Upstream's default and release branches get
+  branch protection with no agent on the push list, plus a rule `<user>/*` per agent. Gitea doesn't stop agent
+  A from creating an unprotected name outside `A/*` unless a catch-all rule outranks the per-agent ones. That
+  depends on Gitea's rule priority, which I haven't verified on our version (probe P1). Every hire adds a rule.
+
+Token scopes for either: `write:repository` and `read:user`, nothing else, per vocabulary.mjs rules (no
+`all`, no admin).
+
+D11. **The host git socket.** `publish` is added to the socket. `push`, `fetch` and `land` don't change. The
+socket's bind rule (E4) adds `git.push.remote`. The working repo stays credential-free and remote-free. The
+`fork` URL is passed per call and never written into its config. A landing still squashes into the project
+root as "Mosaic bus host". Landings don't push anywhere.
+
+## 6. Lifecycle (brief item 4)
+
+All verbs are on the bus, in the CLI (`mosaic credentials ...`) and in the Console's agent page. Every verb is
+human-only. Under Q173 the tester may run `status` and `revoke` on the dev stack instance. `issue` and
+`rotate` stay with Jason, because the tester is an agent and the token would pass through its session
+(duckworth N1). Each one appends to the organization
+writer's `changes.jsonl` (actor, agent, kind, verb, date; never a value). No schema migration, no new event
+kind. A refusal uses `action.refused`.
+
+| Verb | What it does |
+|---|---|
+| `issue AGENT KIND --rotate-by DATE` (gitea) or `--expires DATE` (vikunja) | Reads the token on stdin (never argv), checks E2's format, writes `<kind>.tmp` 0600, fsyncs, renames over `<kind>`, and sets the business file reference to `{"store": true, date}`. The bus reloads that one entry, with no restart |
+| `rotate` | Same as `issue` over an existing entry. The old value is gone from disk and memory when the call returns. Jason then deletes the old token in Gitea (A5) |
+| `revoke AGENT [KIND] --reason` | Drops the entry from the bus's memory first, then unlinks the file. A use in flight finishes. Every later use refuses `credential-unavailable` |
+| `delete AGENT` | `revoke` for every kind, then removes the agent's dir. Refused while the agent has a running claim |
+| `status [AGENT]` | Kind, date and state per entry (E3's `status()`), no values |
+
+D12. **"Stops working at once."** On our side this holds without a timing window. A fired agent never holds a
+`gitea` or `vikunja` token (D3), so revoking means the bus no longer has it. On the Gitea and Vikunja side the
+token still exists until Jason deletes it (A5). The status line for a revoked entry says so until Jason
+confirms. The model token is the exception: it sits in the running sandbox (D7), so a fired agent's runs must
+end. Row 194's fire ends them.
+
+D13. **What row 194 calls.**
+
+- `credentials.issue` is never called by the chief. Row 194's hire stays uncredentialed (its D1).
+- A human `create` of a credentialed definition: row 194 lifts E9's refusal for the human path only. The agent
+  is created with `store` references and no files. `launch` refuses `credential-unavailable` until Jason runs
+  `issue`.
+- `fire` and `delete`: row 194 calls `credentials.revoke(business, agent, {reason, actor})` before it changes
+  the business file. A failed revoke stops the fire (`credential-revoke-failed`), so an agent can't be fired
+  with its credentials still live on our side.
+- `regenerate`: no credential change.
+
+## 7. Who does what (brief item 5)
+
+Agents never mint accounts or tokens. Jason's steps, per agent that needs `gitea`:
+
+- A1. Create the Gitea user: Site Administration, User Accounts, Create User Account. The name is the agent's
+  `gitea.user`. The email is the agent's `identity.email`.
+- A2. Create its token: sign in as that user, Settings, Applications, Generate New Token, scopes
+  `write:repository` and `read:user`, nothing else.
+- A3. Create the fork of each granted repo as that user (O1). Gitea's push-to-create
+  (`ENABLE_PUSH_CREATE_USER`, `ENABLE_PUSH_CREATE_ORG`) stays off, so a push to a missing `<user>/REPO`
+  fails rather than creating a plain repository (N11). `publish` refuses `fork-unavailable` before that.
+- A4. On the stack instance's VM, as its OS user: `mosaic credentials issue AGENT gitea --rotate-by DATE`, with
+  the token pasted into stdin.
+- A5. On fire or rotate: delete the token in Gitea (Settings, Applications), or disable the user.
+- A6. Model: sign in to the provider on each VM user to write `<configDir>/secrets/claude-session.env`.
+
+Vikunja bot accounts and tokens are already Jason's (tracker bots). Only A4 changes for them.
+
+## 8. Migration (brief item 6)
+
+- M1. Existing `{file}` and `{env}` references keep working. A business moves one agent at a time with
+  `issue`, which rewrites that agent's reference to `store`.
+- M2. Nothing here touches the dev repository's helper, its `.git/config`, `~/.mosaic` or `~/.mosaic-dev`.
+  Dev seats (jarvis, seat tokens) keep pushing as today. The mos-0981 rule ends only when Mos says so.
+- M3. The live dev stack instance needs no change at re-pin: no reference uses `store` until someone issues
+  one.
+
+## 9. Questions
+
+Mos ruled on the authority model in mos-1027 (2026-10-20T19:27Z):
+
+- Q-M1. O1, one fork per agent.
+- Q-M2. `git.push.remote` and its bounds in D9 to D11 are approved. It lands as a hard wait: out of ROUTED,
+  and no role grants it within-role (D9 step 1). Sage puts its routing in the PRD version draft going to
+  Jason with `role.hire` and `role.fire` (Vikunja #420). After his approval, a reviewed commit routes it and
+  grants it to coder.
+- Q-M3. Issue, rotate and delete are human-only, and the chief gets none of them. Under Q173 the dev
+  instance's tester gets `status` and `revoke` only.
+- Q-M4. The model credential stays per stack instance for 10-27. Per-agent model tokens wait for a proxy
+  row.
+
+Open for Jason. Mos takes these to him one at a time:
+
+- Q-J1. The model account for Case 1 and Case 2: existing subscription or a new account.
+- Q-J2. Gitea users and tokens for the agents that need them (A1 to A3).
+
+## 10. What this closes (brief item 7)
+
+- G11: closes the store (D1 to D6) and lifecycle (section 6) for `gitea` and `vikunja`. Still open: per-agent
+  model credentials (D7), and the same-uid limit inside one stack instance (D6).
+- G13: closes "own credentials for git" (D8 to D10). Still open: Gitea API verbs (section 4).
+- C2.5 (git remote): Case 2's books repo can use `publish` once its project names a remote.
+
+## 11. Tests and mutants
+
+All tests use scratch roots, fake tokens and a fake Gitea: `git http-backend` behind a node http server on
+127.0.0.1 that checks basic auth against a fake token and records each ref update. No request leaves the host.
+
+- T1. Layout: wrong mode or owner on a dir or file refuses start. A `{file}` reference into another agent's
+  path refuses `credential-not-yours`. A bus restart after a create without `issue` starts, and the agent's
+  status is `not-issued`. A missing `{file}` still refuses start.
+- T2. `useFor` keys from the cap only. A request naming another agent is refused and leaves one
+  `action.refused`.
+- T3. The fake Gitea serves https on 127.0.0.1 with a cert from a scratch CA made by the test. It reaches git
+  only through the `tls` parameter (D9 step 5). Each refusal test that should reach the network asserts that
+  the first port received the request, so no test passes because git refused http first. `publish`: the
+  happy path lands `refs/heads/<user>/<branch>` on the agent's fork in the fake, which shares root's history, at
+  exactly the decision's commit. Refusals for each step in D9, one test each, including `work-not-yours`. Until routing, a publish with
+  no decision refuses, one with a decision for another task or commit refuses, and a second publish on a
+  spent decision refuses `decision-consumed`. Approve while the latest push is A, push B, publish: refuses
+  `decision-mismatch`, and the fork receives nothing. A push to the working repo between `checkPublish` and
+  the git push refuses with `ref-moved` or `decision-mismatch` (sage-1440, BUILD.md deviation 14). A raise with no recorded push refuses `no-push`. A test pins that `git.push.remote` is in neither ROUTED list
+  and that no `roles/*.json` grants it. A force-push attempt is
+  refused by git's non-fast-forward. A fake fork that answers 302 to a second 127.0.0.1 port: the push
+  fails, and the second port receives no request with an Authorization header. A remote on the right host
+  and a different port is refused at step 2. Two agents granted one project each land on their own fork:
+  agent A's push reaches `/<A's user>/REPO` only and B's reaches `/<B's user>/REPO` only, and the fake's
+  upstream repository receives nothing. An upstream owned by the agent's own user refuses `remote-not-fork`,
+  and so does one whose owner differs from `gitea.user` only in case. With an upstream that shares root's
+  history, a first publish to an empty fork and to an unrelated fork each refuse `remote-unrelated`, and
+  neither fork nor upstream receives objects. A fork that doesn't exist refuses `fork-unavailable`, and the
+  fake records no push. `ls-remote` and the push each reach the fork's path only (the fake records every
+  path). Load refusals (D9c), one test each: a dot segment, an extra path segment, a missing segment,
+  a trailing slash, userinfo, a query, a fragment, an explicit `:443`, a name outside Gitea's rule, and a `gitea.url` with a
+  sub-path. A `.git` suffix loads and builds the fork without it. A `publish` grant on an agent without
+  `identity`, and on one whose definition lacks `gitea`, each refuse at load with the N10 message.
+- T4. Token handoff: the token never appears in argv, env, the fork URL, the working repo config,
+  `changes.jsonl`, events or logs (scan every file under the scratch roots).
+- T5. Lifecycle: issue, rotate, revoke and delete, each live with no restart. After revoke, `publish` and the
+  Vikunja path refuse `credential-unavailable`, and so they do after a bus restart that follows the revoke.
+  The tester can run `status` and `revoke`, and `issue` and `rotate` refuse it.
+- T6. Default: an agent without `identity` commits as E7. Existing `{file}` references load unchanged.
+
+Mutants to kill: drop the cap-derived key in `useFor`, let the request name the destination ref, add `+` to
+the refspec, skip the identity check, put the token in the URL, revoke file before memory, skip the dir mode
+check, allow a `{file}` reference into another agent's dir, make ENOENT on a `store` path fatal again, make
+ENOENT on a `{file}` path silent, a helper that answers any host, drop `http.followRedirects=false`, drop the
+`work-not-yours` check, drop the `remote-unrelated` check, add `git.push.remote` to ROUTED, skip the spent
+check on the decision, drop the `pushCommit` comparison in `#authorityFor`, push by ref name in place of the
+oid, push to the upstream URL in place of the derived fork, run `ls-remote` against the upstream in place of
+the fork, take the fork's owner from anywhere but the agent's `gitea.user`, compare the owner with case, run the
+D9c checks on the raw path in place of the normalized one, read a failed `ls-remote` as empty, skip the tip
+check under the lock, and pass a CA flag in production.
+

+# Row 237: one decision publishes once (#1743)
+
+Megavolt, 2026-10-21 (from `date -u`). Brief: `docs/plans/2026-10-20_agent-credentials.md`
+§ "row 199 follow-up N1", blob dca67d310e1b. Source: Duckworth's row 199 round 1 note N1
+(duckworth-0068). Base: `cb5fdb064` (row 199's landing). Reviewer Duckworth, gate owner Sage.
+
+## The defect
+
+`checkPublish` opens a ticket after checking the decision is unspent. The decision is spent only at
+`recordPublish`, which runs after the bus process has pushed. Two `checkPublish` calls on one decision
+therefore both get tickets, and both push. With different branches, the commit lands on two fork refs:
+`refs/heads/<user>/feat` and `refs/heads/<user>/other`. The second `recordPublish` then refuses
+`decision-consumed`, but by then its push has already reached the fork.
+
+## The fix, and why this option
+
+`checkPublish` refuses `publish-busy` when an open ticket in `#publishes` holds the same business and
+decision (`packages/bus/src/broker.mjs:1038-1040`). It runs after the authority and fact checks, so a
+spent decision still refuses `decision-consumed` first.
+
+The brief's other option, rechecking `#spent` in `publishTarget`, doesn't close the race. Both tickets
+reach `publishTarget` before either push ends, and nothing is spent until `recordPublish`. So both
+rechecks pass and both pushes run. The only state that exists while the first push runs is the open
+ticket, so the check reads that.
+
+A refusal (`publishRefused`) drops the ticket and leaves the decision unspent, so a retry on the same
+decision gets a new ticket. That is row 199's behaviour, unchanged. A within-role publish has no
+decision and isn't affected.
+
+## Tests
+
+- `packages/bus/tests/publish.test.mjs:186`. A second ticket refuses `publish-busy`, on the same branch
+  and on another. After `publishRefused` the retry gets a ticket and a third refuses busy. After
+  `recordPublish` there is one `action.allowed` for git.push.remote and the next call refuses
+  `decision-consumed`. Another agent's decision on the same task isn't held.
+- `packages/cli/tests/publish-socket.test.mjs:269`. End to end through the git socket, the bus runtime
+  and the TLS fake Gitea. While the first publish holds its ticket, a second publish on the same
+  decision to branch `other` gets `publish-busy`. The fake Gitea gets exactly one `git-receive-pack`,
+  the fork has only `refs/heads/coder/feat`, and there is one `action.allowed`.
+
+Runs on this branch, single files:
+- publish.test.mjs: 13/13.
+- publish-socket.test.mjs: 8/8.
+
+## Mutant
+
+M1 removes the `publish-busy` line. Both tests fail:
+- The bus test fails at the first busy assert.
+- The cli test fails because the second publish answers `ok: true` with `ref: refs/heads/coder/other`.
+  That is the defect: two refs on the fork.
+
+Logs are in `/mnt/storage/scratch/megavolt-r237/` (m1-bus.log, m1b-cli.log). `cmp` confirmed
+broker.mjs matched the saved copy after the restore. The first cli mutant run (m1-cli.log) was against
+a hook that recursed on every checkPublish. I fixed the hook to fire only for branch `feat` and reran
+it (m1b-cli.log).
+
+## Residuals, not fixed here
+
+1. **A ticket that never ends holds its decision until the bus restarts.** `#publishes` is in memory.
+   That happens when the host dies between checkPublish and recordPublish or publishRefused. It fails
+   closed (`publish-busy`), and a restart clears it.
+2. **publish-timeout (sage-1440).** The socket files `publishRefused` and drops the ticket, but the bus
+   process's push may still be running. A retry on the same decision can then open a ticket while that
+   push is live. This is the same residual the socket already logs ("the bus process's push may still
+   reach the fork"). Closing it means the runtime's `remotes` must keep the decision busy until its push
+   settles, which reaches into runtime.mjs. That is beyond the brief's two options.
+3. **checkLand has the same shape.** `#landings` takes a ticket per call and the decision is spent at
+   `recordLand`. Whether two landings on one decision can both reach main isn't checked here. That's a
+   follow-up for Sage to row or dismiss.
+
+## Gate
+
+Per the brief: Duckworth approves the manifest, the bus suite and every `scripts/test-*.sh` are green
+on Sage's gate, and M1 is killed. This row also changes a cli test file, so the cli suite (or that file
+alone) should run on the gate too.

+
+Megavolt, 2026-10-21 (from `date -u`). Brief: `docs/plans/2026-10-20_agent-credentials.md`
+§ "Brief: row 237 follow-up, one decision lands once, with tests at the broker", c25785d3d. Source:
+row 237 residual 3, megavolt-0068, megavolt-0069 and sage-1651. Base: origin/refactor f5753c0e8, row 210's landing.
+Reviewer Duckworth, gate owner Sage. Tests only; no source changes.
+
+## Why landing has no row 237 race
+
+Row 237 fixed publish: two tickets on one decision both pushed, because the decision is spent only
+after the push, and a push to a remote fork can't be taken back. Landing has the same ticket shape
+(`checkLand` opens a ticket, `recordLand` spends the decision), but three guards keep one decision
+from landing twice:
+
+1. **land-busy, the outer guard.** `doLand` in `packages/cli/src/git-socket.mjs:351` refuses
+   `land-busy` while another landing runs. The slot is taken before the first await, and freed only
+   when the landing ends. There is one git socket per launcher, and one host per dataRoot (host.lock).
+   So through the socket two landings never overlap, and a later one stops at `checkLand` with
+   `decision-consumed`. Even past that, applying the same reviewed patch to the new main fails
+   `base-conflict` in `prepareLand`.
+2. **The CAS on main.** `finishLand` (`packages/seat/src/working.mjs:391`) moves main with
+   `update-ref main <commit> <old>`, so a landing prepared on a tip that has since moved refuses
+   `base-moved` and writes nothing.
+3. **The recordLand recheck.** `finishLand` calls `record()`, which is `recordLand`, under the same
+   repository lock. `recordLand` runs `#landFacts` again (`packages/bus/src/broker.mjs:963`), which
+   refuses `decision-consumed` once the decision is spent. When `record()` throws, `finishLand` moves
+   main back.
+
+Guards 2 and 3 can't be reached end to end, because guard 1 stops a second landing first. So they are
+pinned below the socket, and no test bypasses land-busy.
+
+### The unrecorded-commit window
+
+Between the `update-ref` and the end of `record()`, main names the squash, which isn't recorded yet.
+That window is under the repository's lock, so no other push, review or landing in this host sees
+it. If `record()` refuses, main moves back. If moving back fails, `finishLand` refuses
+`rollback-failed` and main keeps naming an unrecorded commit (tested at `working.test.mjs:555`, the
+main.lock case). That is existing behaviour, unchanged here.
+
+## The test
+
+`packages/bus/tests/land.test.mjs:312`. Two tickets pass `checkLand` on one decision before either
+records. `recordLand` on the first lands. `recordLand` on the second refuses `decision-consumed`
+(:319), and leaves one merge `action.allowed`, one RESULT and no `action.refused`. `landRefused`, as
+the socket would call it, then files the refusal and ends the ticket.
+
+**The assert that pins the recordLand recheck is :319.** The `#spent` line is shared with
+`checkLand`, so dropping it also fails :144 (a `checkLand` after the decision is spent). Only :319
+shows the recheck at record time.
+
+Single file on this branch: land.test.mjs 18/18.
+Whole suites on this branch before in-review: bus 500/500, seat 164/164, cli 565/565 (02:52 to 03:01Z).

+# Row 242 build: a retry after publish-timeout pushes once
+
+Row 242, #1748, P19 440. Brief: docs/plans/2026-10-20_agent-credentials.md, "Brief: row 237
+follow-up N1, a retry after publish-timeout pushes once" (9d165be8c). Base: origin/refactor
+8fede5fc6 (row 210 landed f5753c0e8).
+
+## The defect
+
+The git socket polls publishResult until publishDeadlineMs, then refuses publish-timeout
+(packages/cli/src/git-socket.mjs:433) while the bus process's push (runtime publishPush) can
+still be running. The socket then calls publishRefused, which went straight to
+broker.publishRefused: it filed the refusal and deleted the ticket. checkPublish no longer saw an
+open ticket on the decision, so a retry got a new ticket and pushed a second ref while the first
+push was still on its way to the fork.
+
+## Fix chosen: hold the decision until the push ends, then record a push that reached the fork
+
+packages/bus/src/runtime.mjs, `publishRefused` and `settle`:
+
+- If the bus has no push for the ticket, publishRefused goes to the broker as before.
+- If the push is still running, the refusal code is held on the entry and the ticket stays open.
+  checkPublish refuses another publish on the decision with publish-busy (row 237's check),
+  the same as when the socket is still polling.
+- When the push ends, `settle` runs:
+  - A push that reached the fork is recorded with broker.recordPublish, which spends the
+    decision. The bus logs `pushed after the git socket refused <code>; recorded`.
+  - A push that failed is filed as publishRefused with the socket's code.
+  - If recordPublish refuses with a BusError, that code is filed instead.
+- If the push has already ended when the refusal arrives, it's settled at once. The sage-1440 test
+  relies on this: its push fails fast, so publish-timeout is filed once, immediately, as before.
+
+Why hold rather than kill. Killing the git client doesn't undo a push the fork has already
+received: receive-pack can update the ref after the client dies. After a kill the bus would have
+to ls-remote the fork to learn what landed, and the result could still race the server. Holding
+waits for the push's own outcome. Each git run in publishRemote already has its own limit
+(publishRemote defaults to checkout.mjs GIT_LIMITS), so a hold is bounded. Holding also reuses the existing publish-busy
+state, and the refusal text is unchanged.
+
+Why record and not only hold. If the hold just filed publish-timeout once the push ended, the
+ticket would close and the decision would be free again with a ref on the fork. A retry would then
+push a second ref. Recording the late push spends the decision, so the retry gets
+decision-consumed.
+
+The publish-timeout refusal text is unchanged (brief condition).
+
+## Test
+
+packages/cli/tests/publish-socket.test.mjs:302, "row 242: a retry after publish-timeout refuses
+publish-busy while the bus process's push runs; the late push is recorded and the decision pushes
+once".
+
+- publishDeadlineMs 150 and a store token. The fork's pre-receive hook writes `held`, then loops
+  until the test writes `release`.
+- The first publish gives publish-timeout. The test waits for `held`.
+- A retry to branch `other` gives publish-busy (:322). Refused events: ["publish-busy"]. No
+  git.push.remote allowed event.
+- The test writes `release` and waits until there is exactly one allowed event, with ref
+  refs/heads/coder/feat and the work commit.
+- The next retry gives decision-consumed (:330).
+- Exactly one git-receive-pack request reached the fake Gitea, and the fork has only
+  refs/heads/coder/feat. Refused events: ["publish-busy", "decision-consumed"]. No TOKEN appears in
+  events or logs.
+
+Fail fast (sage-1681): the body is wrapped in try/finally, and the finally writes `release`. Under
+the first mutant run, the assert at the retry failed and the hook was never released. setup's
+teardown waits for the fake Gitea, which waited for the held push, so the file hung until I stopped
+it. Now a failed assert ends the hook and the run. Each wait is bounded at 10 s with an assert.fail.
+
+## Mutants
+
+Script: /mnt/storage/scratch/megavolt-r242/mutants.sh. Each mutant: save, one-line sed, run
+publish-socket.test.mjs whole, restore, cmp.
+
+| Mutant | Change | Expected kill |
+|---|---|---|
+| M1 | export `publishRefused: (ticket, args) => broker.publishRefused(ticket, args)` again (removes the fix) | :302 at :322: the retry gets a new ticket and its own push, so publish-timeout, not publish-busy (seen in the stopped 03:06Z run) |
+| M2 | `settle` files publishRefused without trying recordPublish (hold only) | :302 at the wait for one allowed event, then :330 |
+
+Results (Sage's slot, sage-1686, 2026-10-21T03:35:00Z to 03:35:15Z): both killed, both restored
+(cmp ok).
+
+- M1: publish-socket 8/1, the row 242 test fails at :322 in 0.5 s.
+- M2: publish-socket 8/1, the row 242 test fails at :327, the wait for one allowed event, through
+  the assert.fail inside `until` (:311) after its 10 s bound, in 10.3 s.
+
+## Suites
+
+On Sage's slot (sage-1686), on base 8fede5fc6 plus this row:
+
+- bus `node --test tests/*.test.mjs`: 499/499, 03:35:20Z to 03:35:34Z. This is one fewer than
+  Sage's 241 gate (500) because the base predates row 241's land.test case.
+- cli `node --test tests/*.test.mjs`: 566/566, 03:35:34Z to 03:43:47Z. That's 565 plus the
+  row 242 test.
+
+Singles before the slot: publish-socket.test.mjs 9/9, bus publish.test.mjs 13/13. The seat suite
+and scripts/test-*.sh are left for Sage's landing gate.
+
+## Residuals
+
+- The agent was told publish-timeout, but the push is recorded later and the run isn't
+  notified. The allowed event and the bus log line are the only trace. A later publish on the
+  decision gets decision-consumed, which tells the agent the decision was used. Whether the run
+  should get a RESULT for a late record is a follow-up question for Sage.
+- A late push whose recordPublish refuses (Duckworth N2) is filed with that code: the ref stays on
+  the fork and the decision is not spent, the same residual as an in-band push whose record
+  refuses.
+- The hold lives in the bus process's memory, like the broker's open tickets. A bus restart during
+  a hold drops both, the same as today for any publish in flight.

+- `git patch-id --stable` of the r3 diff (c40d846cb..2369c00e36874e1100b301e0d01cbd105c0c5d4f) equals the r2 diff's (5487ed39d..0f4a57956):

+  because the base moved: `docs/TOOLS.md`, `scripts/stack-copy.sh`, `packages/cli/tests/stack-copy.test.mjs`,
+  `packages/webui/tests/pinned-copy.test.mjs`. The other 19 are byte-identical to r2.

+- Still to do: the full gate on my slot after the MVP gates, then the landing sessions on both harnesses that

+
+What I ask the reviewers: confirm the rebase. In the four drifted files, check that row 66's hunks sit correctly

 no defect is filed.

 Piece 1 is Jason's next real Mosaic Stack request to pm. It is not open yet.
+
+## 2026-10-21T01:14Z dates (sage-1622, Mos mos-1148, Vikunja #442)
+
+Mos accepted the plan with changes C1 and C2. The dates are latest-by markers (Q111).
+
+1. Pieces 1-5 open by 2026-10-23 23:59Z. Mos gives Jason the plain command after tonight's open items with him
+   (Q13 on PRD 1.8, the 1012 and 1008 boot). I don't ask again.
+2. C1: no piece is pinned to a copy. A piece runs on whatever copy is live when Jason sends it. For each piece
+   this log records the activation id at send. A piece still open across a window gets the new activation id
+   recorded too.
+3. C2: neither the Q175 phase 2 window (10-23) nor the 10-24 re-pin window rolls back or restores while a piece
+   has history, unless that window has failed. If a restore happens anyway, this log names the pieces to redo.
+4. All five closed and reviewed by 2026-10-26 18:00Z. Jason reads the five trails at his gate on 10-26 or
+   10-27. A pass starts merge plan step 1 under decision 146, and step 4 stays his.
+5. Fallback: if fewer than five pieces are open by 10-23, the gate moves to 10-28. No agent opens a piece in
+   Jason's place.
+
+When Jason sends a piece, I tell Mos its message id.
+
+Correction (2026-10-21T01:06Z): the heading above says 01:14Z. The clock read 2026-10-21T01:05:56Z when I wrote that entry, so 01:06Z is the right time.
+
+## 2026-10-21T01:20Z Jason's pre-S7 checks (mos-1154)
+
+Between 01:11:06Z and 01:13:03Z Jason sent pm five requests with `mosaic talk pm`: ed9e1e14, 51c19692,
+94f5d62c, 0645a3b7, f75449c0 (bus seq 1583 to 1591). pm run rc9e993da24cf answered each in 4 to 16 s. They were
+two jokes, the sandwich, the purpose of Mosaic Stack and pm's mission. pm made no task and raised no decision
+for any of them, and said so each time. Mos's reading, which I take: none is a piece, because a piece has to
+become work that gets closed and reviewed. They are recorded as Jason's pre-S7 checks. The five pieces are
+still open, latest-by 10-23 23:59Z. Activation at send: copy 4429a104f, as in the 01:06Z entry (C1). Source: Mos
+(mos-1154) read the bus. I didn't read the message bodies.
+
+pm also told Jason that its state snapshot lists only the first 50 of 198 open tasks and that it pages the rest
+with list_tasks. That is the row 109 (#1603) design: broker.mjs `state` returns `cap: TASK_PAGE` (50) with
+`total`, and list_tasks pages up to TASK_PAGE_MAX (200).

+# 10-24 window: re-pin 4429a104f to the row 234 landing, with the 3i-3j migration (draft 0)
+
+Sage, 2026-10-21T01:05Z, draft 0, for mos-1145 under DECISIONS Q173. This is the skeleton. NEW isn't fixed yet,
+so Mos doesn't check this draft. Draft 1 names NEW and goes to Mos for the P0 check. The step layout follows
+`repin-4429a104f.md`. Steps that match are named, not copied.
+
+## Scope (mos-1145, mos-1134)
+
+- One window carries the code of rows 190, 199 and 210, plus row 234 (row a) with its schema step 3i to 3j
+  through `activate --migrate`, agent-run under Q173, backup first.
+- Row a lands before the .53 and .54 installs, by 10-25 (mos-1134). If row 234 hasn't landed by 10-24 12:00Z,
+  I ask Mos whether to run the window without it (no migration) or to move it.
+- Jason has no step. Nobody acts as Jason. No pi (P19 383). No Save, no `mosaic name`. Nothing is pruned.
+- `--sso` stays off. Row 200's `activate --sso` is in NEW as a tool. Turning it on changes who reaches the Console
+  from outside, so that's Jason's (Q173 exclusion). It has its own window, the Q175 phase 2 window on 10-23
+  (mos-1148). That window runs first, so this window's OLD may be the phase 2 copy, and P1 reads it from
+  `status`.
+
+## Names
+
+- OLD, live: `4429a104f6d65ccf165f6c83b5d1dce3147dfde0`, schema 3i, pointer `pm: true` (record 99a406ed3).
+  P1 re-reads the activation id and the Console flags from `status`. I don't copy them from the last window.
+- NEW: `c771a36f4bd0b6c359282425c668996a90072f93`, the row 234 landing (2026-10-21 06:16Z), unless Mos rules a
+  later code landing. 194 is the open candidate. 210, 237, 232, 241, 242, 233 and 234 have landed.
+- REPO, `P`, `WIN=agents/sage/work/window-repin-<NEW12>/`, `SNAP`: as in `repin-4429a104f.md`, with the
+  sha checks at P0 and before S1, S2 and any D3.
+
+## What NEW carries over OLD (refactor c771a36f4)
+
+`git log --first-parent 4429a104f..HEAD`, path-limited to packages, scripts, roles, contracts, adapters, skills
+and the package files:
+
+| Row | Commit | Live effect to check |
+|---|---|---|
+| 201 | afad4993f | business: access.json loader. Check: the live business has no access.json, and load stays LOAD_OK (P1). |
+| 204 | d0bbc5c1c | business: 193a viewer level. Same check. |
+| 190 | 00d4cc1f6 | Several instances per host. Touches `stack-release.sh`, `webui-service.sh`, `bus-service.sh`, `stack-copy.sh`. The default instance must render the same units: P2 diffs the rendered units OLD vs NEW for `mosaic-stack`, and any difference stops the window until it's explained. |
+| 200 | 9e1085816 | Tool: `activate --sso`. Off here. `--plan` must show no `--sso` line. |
+| 199 | cb5fdb064 | Credential store per agent. Check: bus start with no store entries for the live agents changes nothing, and the chief's and pm's launches still pass. The P3 rehearsal covers start. |
+| N3 | 390ea5261 | README only. |
+| 230 | c8bc5cf4c | Case 2 scripts, tools only. Not run live. |
+| 210 | f5753c0e8 | Host access. The live business has no `hosts`, so nothing is granted. Bus start runs the host-run sweep (M34d). P3 must show it removes nothing. |
+| 237 | d7d943199 | Publish busy check (199 N1). |
+| 232 | e65a3ab4d | Installer I1: `stack-release.sh --units external` and `stack-copy.sh copy --bundle`, `wrapper --create`. Both are opt-in, and this window uses neither. The default units path must render the same units, so the P2 unit diff covers it with row 190. P0 checks that no window command line carries `--units external`. |
+| 241 | 5d4a61776 | Test only (bus land.test.mjs). No live effect. |
+| 242 | 5fb736b92 | Bus publish hold: after publish-timeout the bus holds the decision until its push ends, then records a late push. The live business has no publish in flight at W1, and P3 shows none open. Its follow-up fc1cb856b is comments only (git-socket.mjs). |
+| 233 | 57f59e0c3 | Installer I3: new tool `scripts/stack-upgrade.sh` and a `stack-release.sh` change. This window doesn't run `stack-upgrade.sh`. The P2 unit diff covers the `stack-release.sh` change with rows 190 and 232. |
+| 234 | c771a36f4 | Machine grant row a and the 3i to 3j schema step (new tables `hosts` and `host_grants`). `--plan` must say `migration: 3i -> 3j`. |
+| PRD 1.7+1.8 | 0adf8ddfe | `docs/prd/mosaic-stack.md` and `packages/tasks/requirements.json` move to version 1.8 (mos-1154, mos-1156, DECISIONS Q192). The live pm cites 1.6 until this window. Check after: the pm's requirements read answers version 1.8. |
+
+Service script drift OLD to HEAD is 415+/91- over the four scripts, mostly row 190. P5 holds them at NEW.
+
+## Backups and the migration
+
+- W5: the stopped store backup that every activate takes (row 185), with SHA256SUMS, SCHEMA 3i and STAMP,
+  plus the rollback set. Before `--migrate` writes, I check that SCHEMA reads 3i and the backup SHA256SUMS hash.
+- W0b: the business file copy, as in the last window.
+- Rollback after a migration isn't the plain rollback. OLD is 3i and the store is 3j, so going back needs
+  `--restore <W5 activation>`, and that loses the events written after W5. The row 181 restore guard counts
+  11 tables, and the untimed ones need the D3 snapshot. Row 234 adds `hosts` and `host_grants` to the untimed
+  list (T46), so at 3j the D3 snapshot covers them too. Draft 1 recounts the list from NEW. Mos decides any restore past W5, as before.
+- Grant look-alikes (row 234 A22b, gizmoduck-0107). `3i-3j.sql` adds `events_grant_actor` but doesn't check
+  rows already in the store, so after the migration only the actor filter in `GRANT_EVIDENCE` (actor_role NULL,
+  actor_run 'grant') ignores an old session-written row. P3, and again just before `--migrate`: on the
+  backup copy, count the `action.allowed` events whose body.action or body.operation starts with `grant.`, or
+  whose body has `hostLineLeft`. Expect 0, since no grant code has run live. Any nonzero count stops the window
+  until I've read those rows.
+- P3 is the rehearsal with `--migrate` on a copy of the live backup. It must show the 3j step and the row
+  counts before and after.
+
+## Row 42 (S7) interaction
+
+Row 42's pieces may be in flight at window start (sage-1622, mos-1148 C1 and C2). W1 adds: list open pm tasks, and either pm
+finishes or parks them before W5, or I record which piece crosses the window. No restore while a piece has
+history unless the window fails.
+
+## Open before draft 1
+
+- Q1, ruled by mos-1161: draft 1 doesn't wait for 194. NEW is the latest code landing when I cut draft 1. If
+  194 has landed with a green full gate (15 packages, ten script suites), NEW is the 194 landing and P3 also runs
+  the lifecycle verbs once on the backup copy and gets one pm reply under the new roles/chief-of-staff files. A
+  P3 failure that traces to 194 drops NEW back to c771a36f4 before anything touches live, and the window goes on.
+  Otherwise NEW is c771a36f4 and 194 rides a later window.
+- Q2, settled by mos-1148: phase 2 is its own window on 10-23. Draft 1 takes OLD and the Console flags,
+  `--sso` included, from `status` after that window.
+- Q3: who operates. If Darkwing is free, Darkwing operates and I check. Otherwise I operate as in the last
+  window.
+- The P-step evidence list for rows 199 and 210 at bus start. Both have landed (cb5fdb064, f5753c0e8), so
+  it's due in draft 1. I take each log line and exit code from a P3 rehearsal run, not from the code.
+- Rows 241 and 242 (bus): P3 shows no publish or land decision open before W5.

+#### Root-owned units (`--units external`, row 232)
+
+On a host whose bus and Console are root's system units, the stack user runs
+`stack-release.sh` with `--units external` from its own clone of the release
+bundle (sage-1561). The script then calls `systemctl show`, `is-active` and
+`list-units` without `--user` and reads no journal. It starts, stops and
+installs nothing. Root does those steps, and the I3 driver calls the verbs
+below in order. Without `--units`, every command line and every byte of
+output is what it was before row 232. `confirm`, `revert`, `gate`, `--to`
+and `--expect-from` are usage errors without `--units external`.
+
+- `adopt`, `status`, `activate ID` and `rollback --to ID` take the flag.
+  `rollback` then needs `--to`, and `--to` must be the copy `rollback` alone
+  would pick from the log, or it refuses `to-not-previous`.
+- `--plan --expect-from OLD` refuses `pointer-differs` when the pointer
+  names a copy other than OLD.
+- `pm-on` and `activate --pm-after-harness` refuse `external-pm`; the PM
+  flag is in root's bus unit. `--pm`, `--tester-port`, the proof flags,
+  `--no-proof`, `--no-send` and `--sso` are usage errors; root's Console
+  unit carries the Console flags.
+- `activate` and `rollback` refuse `units-running` unless both units read
+  inactive or failed and the store is closed. They make the rollback set
+  with an exclusive `mkdir`, write `AWAITING-UNITS` (the target copy) first,
+  capture the pointer, the wrapper and both units' show output and unit file
+  sums, back up and migrate or restore the store, and write the wrapper.
+  They write no pointer and start nothing. The last line says the run is
+  staged and names `confirm`. A failure after the capture writes `FAILED`
+  with its code, logs nothing more and exits 1; the activation stays open.
+- `confirm ID BUSINESS` needs exactly one `AWAITING-UNITS` for copy ID whose
+  activation the log holds open, or it refuses `open-activation`. It gates
+  the start root made and writes the pointer and an `ok` line with the
+  started line's op, from, to and backup.
+  `confirm --rollback OLD --cause A3|A4|A5` gates OLD after root put the old
+  units back and logs `failed` or `gate-failed` with `rollback ok` (exit 1)
+  or `rollback-failed` (exit 2). Either removes `AWAITING-UNITS` and `FAILED`.
+- `revert ID BUSINESS` puts the saved wrapper back and, when the run had
+  started a migration, restores the backup taken before it. It writes no log
+  line and can run again.
+- `gate ID BUSINESS --since EPOCH` gates a copy with no open activation,
+  takes no lock and writes nothing: 0 on a pass, 1 otherwise. EPOCH is root's
+  clock before root started the units.
+
+The gate under `--units external` replaces the journal read. The bus unit's
+`ActiveEnterTimestamp`, in whole seconds, must be at or after the started
+line's second (`confirm`) or `--since` (`gate`); an older start fails
+`stale-start`, so a unit that never stopped can't pass. With the PM on, the
+gate reads `launches list --json` for exactly one live launch of the PM's
+instance (the business's `launch.by`), for this business, whose run started at
+or after the floor. `status` adds an
+`awaiting units:` line for an open activation.
+
+Under `--units external`, `activate --plan` also refuses `open-activation`
+while any rollback set holds `AWAITING-UNITS`, and `migrate-required` when
+the target migrates the store and the run lacks `--migrate` (row 233). Under
+`--units user` the plan's bytes are unchanged.
+
+#### Root's upgrade driver (`scripts/stack-upgrade.sh`, row 233)
+
+```
+scripts/stack-upgrade.sh upgrade --instance dev --bundle FILE --sha SHA [--migrate] [--no-rehearsal]
+    [--rehearse-port N] [--timeout S]
+scripts/stack-upgrade.sh rollback --instance dev --to ID [--restore ACT [--events N]] [--timeout S]
+```
+
+Root runs it from a root-owned checkout of the reviewed commit, never from a
+copy, because the stack's user can write the copies. Each run needs Mos's go,
+and `--migrate` needs Jason present (decision 96). The host must be prepared
+first (`docs/guides/host-run-sheet.md`). Only the default instance, `dev`, is
+accepted; a named instance's units are a later row.
+
+The unit values come from `/etc/mosaic-stack/dev.args`, which I2's install
+writes: one `case2-unit.sh` argument per line, the serve flags after `--`,
+owned by root with no group or other write, exactly one `--copy`, and that
+copy the one both installed units run. Otherwise the run refuses
+`args-unreadable` or `args-differ`. The driver writes the new copy id into
+that file only after `confirm` passes.
+
+`upgrade`, in order. Every stack user step runs as
+`sudo -u USER -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin` from the
+user's clone `<home>/src/mosaic-stack`:
+
+1. Takes `flock -n` on `/run/mosaic-stack/upgrade-dev.lock` and holds it to
+   the end, rollback included. A second run refuses `upgrade-running`, and
+   a lock it can't open refuses `lock-failed`.
+2. Fetches the bundle's `refactor` into the clone and fast-forwards it to
+   SHA (`fetch-failed`), then `stack-copy.sh copy --bundle FILE SHA`
+   (`copy-failed`).
+3. A1: this checkout's HEAD is SHA (`head-mismatch`), the copy exists
+   (`copy-missing`), `/usr/local/lib/mosaic-stack/hostcheck.sh --check`
+   exits 0 (`profile-drift`, row 240), both units name one copy
+   (`units-unreadable`, `units-disagree`) and it is the args file's
+   (`args-differ`), and
+   `activate SHA BUSINESS --units external --plan --expect-from OLD` exits 0
+   (`plan-refused`, which covers `open-activation`, `migrate-required` and
+   `pointer-differs`).
+4. The rehearsal, `rehearse SHA BUSINESS --backup last --port 7339`
+   (`--rehearse-port`). Exit 0 goes on. Exit 3 means no backup in the log
+   and goes on only with `--no-rehearsal`, logging `rehearsal-skipped`;
+   without the flag it refuses `no-backup`. Exit 0 with `--no-rehearsal`
+   refuses `rehearsal-required`; any other exit refuses `rehearsal-failed`.
+5. A2 stops the Console, then the bus, and waits for both to read inactive
+   or failed. A3 is `activate --units external`, A4 the render with the new
+   `--copy` (which also starts the bus, then the Console), A5 `confirm`.
+   The driver writes the new args file beside the old one before A2
+   (`args-failed`, exit 3) and moves it into place after A5. A failed move
+   exits 5 `args-failed`: the new copy is live and confirmed, the args file
+   still names the old one, and root moves the new file (the result line
+   names it) into place by hand.
+
+A failure in A2 or a stage that exits 3 starts the old units again and gates
+them (A2f). A later failure stops both units, runs `revert`, renders the old
+copy and runs `confirm --rollback OLD --cause A3|A4|A5`. `rollback` is the
+same from A1 on, with `rollback BUSINESS --to ID`, no fetch, no copy and no
+rehearsal; `--restore` and `--events` pass through.
+
+Root reads no output the stack user wrote except exit codes and the
+rehearsal's `BACKUP_STORE` line, which it copies into its log after a match
+against a fixed pattern (`BACKUP_STORE none` otherwise). The step log
+`/var/log/mosaic-stack/upgrade-dev.log`, 0640, gets one
+`<time> <step> rc=N argv: ...` line per step and a last
+`<time> result exit=N <code> <text>` line.
+
+Exit 0 ok, 1 failed with the old stack running and gated, 2 rollback-failed
+with both units stopped, 3 refused with nothing stopped, 4 usage, 5
+args-failed with the new stack live and confirmed. A refusal
+after step 2 leaves the user's clone fast-forwarded and the new copy made. After exit
+2 the activation stays open, so the next run's plan refuses until root
+finishes it.

+The pins are the profile's sha256, the `apparmor-profiles` version it came
+from and the bubblewrap install pin; changing one is a reviewed commit.
+Seven items, one `ok N` or `FAIL N` line each: the profile file matches the
+pin and no package owns it; `aa-status` has `bwrap` and `unpriv_bwrap` in
+enforce mode and no `mosaic-bwrap`; no other file under `/etc/apparmor.d`
+names `bwrap`; a bwrap child under the units' no-new-privs reads
+`bwrap//&unpriv_bwrap (enforce)`; `/usr/bin/bwrap` is `root mosaic 0750` by
+the statoverride and by `stat`; the user-namespace restriction and
+`fs.protected_hardlinks` are 1; `net.ipv4.ip_unprivileged_port_start` is
+above the Console unit's `--port`, or above 1023 with no unit. A `note` line
+says whether bubblewrap is the install pin and never fails.
+
+`--check` exits 0 or 1; `stack-upgrade.sh` refuses `profile-drift` on 1.
+`--enforce` exits 0. On a failure, or while `/etc/mosaic-stack/DRIFT` exists,
+it unloads the profile if loaded, sets `/usr/bin/bwrap` to `root:root` 0700,
+appends the failed items to `DRIFT` and one line to
+`/var/log/mosaic-stack/hostcheck.log`. It never writes the statoverride. The
+apt hook runs it after every package run, and `mosaic-hostcheck.service`
+(`packages/cli/systemd/`) at boot before the bus. `--upstream` compares the
+`apparmor-profiles` candidate's profile to the pin, prints any difference
+and exits 0, or 1 when the download fails. Exit 2 is usage or a refusal:
+root takes no `--root` (the test seam), and other users run only with it.

+`bwrap.orig`; `apparmor_parser -R /etc/apparmor.d/bwrap-userns-restrict`, then `rm` it;
+`apt-get remove bubblewrap`.
+
+The no-new-privs test must print `bwrap//&unpriv_bwrap (enforce)`:
+
+```sh
+systemd-run --wait --pipe --uid=mosaic --gid=mosaic -p NoNewPrivileges=yes -p ProtectSystem=strict \
+  -p ProtectHome=yes -p PrivateTmp=yes \
+  /usr/bin/bwrap --unshare-user --unshare-pid --ro-bind / / cat /proc/self/attr/current
+```
+
+The P9 checks: another user's `/usr/bin/bwrap --version` fails with Permission denied, `getent group mosaic`
+lists no member, and `sysctl fs.protected_hardlinks` prints 1. `sysctl
+kernel.apparmor_restrict_unprivileged_userns` prints 1 too (Ubuntu 24.04's default); leave it, so nothing
+else on the host gains user namespaces.
+
+The drift stop (row 240, I4, #1746) goes in last, after the profile and the statoverride. As root, from
+the root-owned checkout of the reviewed commit:
+
+```sh
+install -d -o root -g root -m 0755 /usr/local/lib/mosaic-stack
+install -o root -g root -m 0755 scripts/case1-hostcheck.sh /usr/local/lib/mosaic-stack/hostcheck.sh
+install -o root -g root -m 0644 scripts/case1-pins.sh /usr/local/lib/mosaic-stack/case1-pins.sh
+printf '%s\n' 'DPkg::Post-Invoke { "/usr/local/lib/mosaic-stack/hostcheck.sh --enforce || true"; };' \

+install -o root -g root -m 0644 packages/cli/systemd/mosaic-hostcheck.service /etc/systemd/system/
+systemctl daemon-reload && systemctl enable mosaic-hostcheck.service
+/usr/local/lib/mosaic-stack/hostcheck.sh --check
+```
+
+`--check` prints one `ok` line for each of its seven items and exits 0. Item 7 reads 1023 as the port
+until I2 installs the Console unit (section 10), then the unit's `--port`. `stack-upgrade.sh` runs `--check`
+before its plan and refuses `profile-drift` on any exit but 0, a missing file included. Rollback:
+`systemctl disable mosaic-hostcheck.service`, then `rm` the unit, the hook file and
+`/usr/local/lib/mosaic-stack`.
+
+On drift, `--enforce` (the apt hook after every package run, and the unit at boot) unloads the profile,
+closes `/usr/bin/bwrap` to `root:root` 0700, appends the failed items to `/etc/mosaic-stack/DRIFT` and logs
+a line in `/var/log/mosaic-stack/hostcheck.log`. Every role session then refuses to start. ops-01 reads the
+log in each STATE report and sends any `DRIFT` to Mos. Only root removes `DRIFT`, in a reviewed step with
+a new pin or a Mos go. After that, `chown root:mosaic /usr/bin/bwrap`, `chmod 0750 /usr/bin/bwrap` and
+`apparmor_parser -r /etc/apparmor.d/bwrap-userns-restrict` put bwrap back, and `--check` must exit 0.
+
+Before each re-pin window, ops-01 runs `/usr/local/lib/mosaic-stack/hostcheck.sh --upstream`. It
+downloads the `apparmor-profiles` candidate and compares its `bwrap-userns-restrict` to the pin. A
+`DIFFERS` line goes to Mos as a new-pin request; it refuses nothing.
+
+Precheck lines:
+- `ok      bwrap --unshare-all runs`
+- The AppArmor profile, the statoverride, the no-new-privs result and the P9 checks: precheck line missing.
+  `/usr/local/lib/mosaic-stack/hostcheck.sh --check` covers them (row 240).
+
+## 5. The port floor
+
+Leave `net.ipv4.ip_unprivileged_port_start` at its default (1024) or higher. The Console's port is below
+it and the unit gets `CAP_NET_BIND_SERVICE`, so no other `mosaic` process can bind that port.
+
+Precheck line: `ok      net.ipv4.ip_unprivileged_port_start <n> is above the Console's port <port>`.
+
+## 6. The release transport
+
+A release is a git bundle of `refs/heads/refactor` plus the 40-character commit id (I1, mos-1118 choice 2).
+Mos's go names both, with the bundle's sha256. `<sha>` below is that id.
+
+First install:
+
+```sh
+# Copy the bundle in, then check it before anything reads it.
+echo "<bundle sha256>  /root/<sha>.bundle" | sha256sum -c -
+git bundle verify /root/<sha>.bundle
+
+# Root's checkout. stack-upgrade.sh and case2-unit.sh run from here, never from a copy.
+git clone -q -b refactor /root/<sha>.bundle /root/mosaic-stack
+git -C /root/mosaic-stack checkout -q --detach <sha>
+git -C /root/mosaic-stack rev-parse HEAD        # must print <sha>
+
+# The stack's user's copy of the bundle, and its own clone.
+install -d -o mosaic -g mosaic -m 0700 /srv/mosaic/incoming /srv/mosaic/src
+install -o mosaic -g mosaic -m 0600 /root/<sha>.bundle /srv/mosaic/incoming/<sha>.bundle
+sudo -u mosaic -H git clone -q -b refactor /srv/mosaic/incoming/<sha>.bundle /srv/mosaic/src/mosaic-stack
+```
+
+Each upgrade, before `stack-upgrade.sh upgrade`:
+
+```sh
+echo "<bundle sha256>  /root/<sha>.bundle" | sha256sum -c -
+git bundle verify /root/<sha>.bundle
+git -C /root/mosaic-stack fetch -q /root/<sha>.bundle refs/heads/refactor:refs/remotes/origin/refactor
+git -C /root/mosaic-stack checkout -q --detach <sha>
+install -o mosaic -g mosaic -m 0600 /root/<sha>.bundle /srv/mosaic/incoming/<sha>.bundle
+/root/mosaic-stack/scripts/stack-upgrade.sh upgrade --instance dev --bundle /srv/mosaic/incoming/<sha>.bundle --sha <sha>
+```
+
+The driver fetches the bundle into the stack's user's clone and makes the copy itself. It refuses
+`head-mismatch` when root's checkout isn't at `<sha>`. Usage, exits and the step log are in
+`docs/TOOLS.md`, under "Root's upgrade driver". Each run needs Mos's go, and `--migrate` needs Jason present
+(decision 96).
+
+When a run doesn't exit 0, send Mos the exit and the last lines of `/var/log/mosaic-stack/upgrade-dev.log`:
+- Exit 3: refused before anything stopped. The last line names the code. The stack's user's clone and the
+  new copy may already hold the new commit; the units still run the old one.
+- Exit 1: the old copy runs and passed its gate. Either the driver restarted it after A2 or a refused A3
+  (A2f), or it rolled back after A3, A4 or A5.
+- Exit 2: both units are stopped and the activation stays open, so the next run refuses at its plan until
+  it is finished with `confirm` or `revert`. One way here: a unit that doesn't stop within `--timeout`
+  keeps its old start time, A2f's gate fails it `stale-start`, and the driver stops both (duckworth-0055
+  N1). That is on purpose; a unit that won't stop is a reason to stop.
+- Exit 5: `args-failed`. The new copy is live and passed confirm, but `/etc/mosaic-stack/dev.args` still names
+  the old copy. The next run refuses `args-differ`, and a render from that file would put the old copy back.
+  Move the file the result line names into place with `mv -f`. The two differ only in the `--copy` value.
+
+Precheck lines: none. Root's checkout at `<sha>` and the stack's user's clone: precheck line missing.
+After install, `stack-copy.sh check --units external` reads the copy the units run.
+
+## 7. The args file
+
+`/etc/mosaic-stack/dev.args` holds the `case2-unit.sh` arguments, one per line, with the serve flags after a
+line holding `--`. I2's install writes it; ops-01 doesn't write it by hand. It must be root's, with no group
+or other write (`chmod 0644` or tighter). Before `--` it takes only `--user`, `--home`, `--business`,
+`--copy` (exactly once), `--node`, `--profile`, `--claude` and `--pm`. `stack-upgrade.sh` changes only the
+`--copy` line, and only after confirm passes.
+
+Precheck line: none. `stack-upgrade.sh` refuses `args-unreadable` on any of these rules.
+
+## 8. Enrollment, once per host
+
+The machine-grant enrollment is Gizmoduck's design r6, commit f9039682e, section 3, steps E1-E4. ops-01's
+Q-O1 is answered (mos-1125). The host side is the `tools/host/` files: `mosaic-keys`, `mosaic-keys-write`,
+their sudoers line and the sshd drop-in `/etc/ssh/sshd_config.d/<nn>-mosaic-keys.conf`. The verbs that run
+it (`hosts.enroll`, the `host-enroll` decision) are rows 234 and 235, not yet on refactor. This item has no
+commands until they land.
+
+Precheck line: none. The enrolled host's key and its `mosaic-keys` sudoers line: precheck line missing.
+
+## 9. Credential slots
+
+Jason places these, all in one sitting per host. No value appears here or in any message. Check a placed
+file with `stat -c '%U %a %n' PATH`, never `cat`. `<business>` is the host's business id.

+## Brief: #436b Gitea grant path, build (schema 3j-3k)
+
+Sage, 2026-10-20, for Vikunja P19 #436 (#436b), mos-1124 (Q190: each seat gets its own Gitea account through
+this row) and mos-1145 (Gitea moves to 10-27, at risk). Owner Megavolt, reviewer Dewey, gate owner Sage.
+Gitea #1742.
+
+The design is `agents/megavolt/work/436b/DESIGN.md` r5 at 1be535aca on `megavolt/row199`, sha256
+`68df02cdf890564c6ed0a5426204114389ba7eb0eea1cf04f1bf5938b6de45f4`, which Dewey approved in dewey-0763. Section 7
+was approved by Duckworth at fa5658941 (duckworth-0067) and is unchanged since. It is not reopened here. The
+build also takes `agents/megavolt/work/436b/BUILD-CARRY.md` at 3330c901b (Dewey's N9 and N10), and its BUILD.md
+cites that file.
+
+Scope: the Gitea half only. The binding (section 2), the executor and its admin credential (sections 3 and 4),
+failure and restart (section 5, with sage-1578's option (b): a step 0 refusal stays unspent only until the
+next start), revoke and sweep (section 6), the store records (section 7) and section 9's tests and mutants. The
+GitHub half (section 10, Bushroot) is not in this row.
+
+Order and schema:
+- It builds on row 210's landing (the design: code waits on 210) and on machine grant row a (row 234), whose
+  section 7 rule and `system/grant` writer it shares.
+- This row owns `SCHEMA_VERSION` 3k: its two tables go in `3j-3k.sql` on row 234's landing. Row 206 (193b2)
+  moves to 3k-3l and rebases onto this row's landing (Sage, 2026-10-20: row 205 is still queued behind the
+  federation rows, so this row lands first).
+
+Boundaries:
+- Live use waits for Jason. He approves section 8's notes (the admin token can take over any account on that
+  Gitea) and does the one bootstrap step himself (3e): he creates `mosaic-grant`, its TOTP and its token. No
+  agent creates a Gitea account or token (Q188).
+- No test reaches git.mosaicstack.dev or any provider. Tests use a fake Gitea and fake tokens in scratch roots.

+Megavolt, reviewer Duckworth, gate owner Sage. Builds on row 237's landing d7d943199. Vikunja P19 441.
+
+Landing already has three guards against one decision landing twice. `land-busy` at
+`packages/cli/src/git-socket.mjs:351` allows one landing per socket at a time. `finishLand` moves main by
+compare-and-swap (`packages/seat/src/working.mjs:391`, refusing `base-moved`). `recordLand` reruns
+`#landFacts`, which refuses `decision-consumed` (`packages/bus/src/broker.mjs:945`). So no end-to-end race
+exists, and no code change is planned. What's missing is a test that pins each guard.
+
+- In `packages/bus/tests/land.test.mjs`, add a test where two tickets pass `checkLand` on one decision. The
+  first `recordLand` succeeds and the second refuses `decision-consumed`, with nothing recorded for it.
+- Run three mutants and list them in BUILD.md: drop the `#spent` line in `#landFacts`, drop the old value
+  from the CAS `update-ref` in `finishLand`, and drop the `land-busy` throw at git-socket.mjs:351. Each must
+  be killed by a named test. If the CAS mutant survives `packages/seat/tests/working.test.mjs:555`, add a
+  test to working.test.mjs that kills it. Otherwise leave that file alone.
+- If a mutant survives with no test that can reach it, stop and send me the analysis. Don't change source

+Sage, 2026-10-20, on Mos's go mos-1118 (the mapping in sage-1524, accepted). Vikunja P19 #432. Q187
+(mos-1108): install and upgrade become product commands before either VM gets the stack. ops-01 proves them
+on a throwaway PVE VM, and the same commands then install 10.1.1.53 (Case 1, factory profile) and 10.1.1.54
+(Case 2, library profile).
+
+The work is in three rows:
+- I1 (this file): `stack-release.sh` and `stack-copy.sh` learn system units and bundle copies.
+- I2: rows 230 and 226, re-briefed in `docs/plans/2026-10-20_case2-rows.md` (C2-13a and C2-13b). The install
+  command, the unit render, the precheck and the two profile files.
+- I3 (this file): the root `upgrade` driver and the ops-01 host run sheet.
+
+Row 195 shrinks to the factory profile's values and the Case 1 acceptance
+(`docs/plans/2026-10-20_hub-own-uid.md`).
+
+The source for most of I1 and I3 is row 195's DESIGN r6, `agents/darkwing/work/queue-195/DESIGN.md` at
+b7239bb66, cited below as "r6". r6 designed these pieces for one host under `case1-*` names. These rows
+build them once, for any host, under the stack's own names. Where this brief and r6 differ, this brief
+wins.
+
+Choices Mos accepted (mos-1118). They hold for all three rows:
+1. Install starts on a host that ops-01 has prepared with the run sheet. Install's precheck verifies each
+   prepared item and refuses when one is missing. Folding host prep into the command is a post-10-27 row,
+   Vikunja #437.
+2. The "next release" for the ops-01 proof is two refactor commits shipped as git bundles. I1 makes
+   `stack-copy.sh` take a bundle.
+3. Decision 96 stays as process: Mos's go per run, and Jason present for `--migrate`. `upgrade` refuses a
+   migrating target unless `--migrate` is given.
+4. The instance gets its name through row 190's `--instance NAME`. .53's profile value is `dev`, r6's
+   name, which is row 190's default instance (`scripts/instance.sh`, "other than dev").
+5. The Console starts by itself on both hosts (Q189, mos-1122). I2 renders and enables it. Nothing in I1
+   or I3 starts it by hand.

+## I1 stack-release external units and bundle copies
+
+Gitea #1734. Vikunja P19 #432.
+
+### Problem
+
+`stack-release.sh` calls `systemctl --user` and `journalctl --user` throughout, so it can't run a stack
+whose units are system units owned by root, as both VMs' are. `stack-copy.sh` makes a copy only from a
+commit reachable from `refs/heads/refactor` and `refs/remotes/origin/refactor`
+(`scripts/stack-copy.sh:36-41`), and a VM has no such checkout. Its `wrapper` verb refuses when no wrapper
+exists yet (`:68-73`), so a first install can't make one.
+
+### Owner and reviewer
+
+- Owner: Darkwing.
+- Reviewer: Filbert (moved from Duckworth, mos-1119 item 4).
+- After: row 190, landed as 00d4cc1f6 on 2026-10-20. Build on 00d4cc1f6 on a new branch, then rebase to a
+  new branch name if refactor moves under a path this row owns. Never force-push. Row 200 (Launchpad,
+  `activate --sso`) also changes `scripts/stack-release.sh` and is rebasing onto 00d4cc1f6 now. Whichever of
+  the two lands second rebases onto the other.
+
+### Files owned
+
+`scripts/stack-release.sh`, `scripts/stack-copy.sh`, `packages/cli/tests/stack-release-external.test.mjs`
+(new), `packages/cli/tests/stack-copy.test.mjs`, `packages/cli/tests/stack-release.test.mjs` where a
+shared helper moves, and the `docs/TOOLS.md` and `packages/cli/README.md` lines for these verbs.
+
+### What ships
+
+- `--units user|external`, default `user`. Under `user`, every command line and every byte of output is
+  what it is today, and the existing tests pass unchanged. One units backend holds every `systemctl` and
+  `journalctl` call, so the two modes differ in that one place.
+- Under `external`, r6's pieces, as designed there:
+  - `adopt`, `activate`, `rollback` and `status` (r6 :313-316, :459-559).
+  - The open-activation marker `AWAITING-UNITS` and the `confirm`, `revert` and `gate --since` verbs, which
+    refuse without `--units external` (r6 :443-457).
+  - `rollback --to ID`, which refuses unless ID is `from_log previous` (r6 :545-555).
+  - `--plan --expect-from OLD`, which refuses `pointer-differs` (r6 A1, N5).
+  - The start floor from the bus unit's `ActiveEnterTimestamp`, compared in whole seconds, with gate code
+    `stale-start` (r6 :491-505).
+  - The PM check from `launches list --json`, with no journal read (r6 :507-523).
+  - `pm-on` and `activate --pm-after-harness` refuse `external-pm` (r6 :525-526).
+- `stack-copy.sh check --units external`, which reads the system units (r6 :739-741).
+- `stack-copy.sh copy --bundle FILE SHA`. It runs `git bundle verify`, requires the bundle to carry
+  `refs/heads/refactor` with SHA reachable from it, and makes the copy from SHA as `copy` does today. It
+  prints the `RELEASE` value at SHA and the bundle's sha256. Without `--bundle`, `reachable` stays as it is.
+  This is the release identity for a host with no refactor checkout.
+- `stack-copy.sh wrapper ID --create`. It writes the first wrapper only when none exists at the wrapper
+  path, and refuses when one does. Without `--create`, today's refusal on a missing wrapper stays.
+
+Where the stack user's `stack-release.sh` runs (darkwing on sage-1558, ruled sage-1561): from the stack
+user's own clone of the release bundle under its home, as in r6 step 2b. Each upgrade fetches the new bundle
+into that clone's `refs/heads/refactor` and `refs/remotes/origin/refactor`. So `check_target`'s reachability
+(`scripts/stack-release.sh:226`, `:258`), the plan's commit list (`:929-938`) and status drift (`:1220`)
+work unchanged under `external`, and I1 changes no reachability rule. "A VM has no such checkout" above
+means no canonical development checkout. The stack user never runs from root's checkout, and nothing adds
+`safe.directory`. `copy --bundle` still ships, for the first copy before the clone exists and as the
+release identity.
+
+The installer driver that calls these verbs as root is I3, and the install is I2. I1 has no root step and
+calls no `sudo`.
+
+### Tests
+
+r6 section 7's list for `stack-release-external.test.mjs` (r6 :742-812), all of it, including the eight
+sequences on one log. Plus these:
+- Under `--units user`, a fake `systemctl` that records its argv sees the same calls as before on the
+  existing `activate` and `rollback` tests.
+- A bundle whose `refs/heads/refactor` doesn't reach SHA refuses. So do a corrupt bundle and a bundle with
+  no `refs/heads/refactor`. A good bundle gives a copy byte-identical to `copy SHA` from a checkout.
+- `wrapper --create` refuses over an existing wrapper, and writes a wrapper equal to `wrapper ID`'s
+  output.
+
+Mutants: r6 section 7's list for these verbs, plus one that drops the bundle reachability check and one
+that lets `--create` overwrite.
+
+### Gate
+
+Filbert approves the manifest. The cli suite and every `scripts/test-*.sh` are green on Sage's gate, with
+the mutants killed. Target: in review 10-22, landed 10-23 (sage-1528 line 8).

+## I3 the upgrade command and the host run sheet
+

+
+### Problem
+
+Nothing re-pins a stack whose units are root's. r6 designed `case1-repin.sh` for .53 alone. And nothing
+tells ops-01 what to put on a fresh host before install.
+
+### Owner and reviewer
+
+- Owner: Darkwing. Fallback author: Herb (mos-1118, mos-1119). If I1 isn't approved by 10-23, Herb takes
+  I3 from this brief with no new briefing.
+- Reviewer: Filbert (moved from Duckworth, mos-1119 item 4).
+- After: I1 lands. It calls I2's render, so its tests use I2's candidate or a stand-in with the same
+  arguments.
+
+### Files owned
+
+`scripts/stack-upgrade.sh` (new), `packages/cli/tests/stack-upgrade.test.mjs` (new),
+`docs/guides/host-run-sheet.md` (new), and the `docs/TOOLS.md` lines for the new script.
+
+### What ships: `stack-upgrade.sh`
+
+Root runs it from a root-owned checkout of the reviewed commit, never from a copy, because the stack's user
+can write the copies.
+
+- `stack-upgrade.sh upgrade --instance NAME --bundle FILE --sha SHA [--migrate] [--timeout S]`
+- `stack-upgrade.sh rollback --instance NAME --to ID [--restore ACT --events N] [--timeout S]`
+
+The steps are r6's activate A1-A5, A2f and R1-R4 (r6 :459-544), and r6's rollback (:545-559), with these
+changes:
+- The unit render is I2's, called with the values from `/etc/mosaic-stack/<instance>.args`, which I2's
+  install writes. `--copy ID` is the one value upgrade changes. Upgrade never edits that file except to
+  record the new copy id after a confirmed run.
+- Before A1, `copy --bundle FILE SHA` runs as the stack's user (I1), and the copy id is SHA.
+- A rehearsal runs before A2, as the stack's user: `stack-release.sh rehearse SHA BUSINESS --instance
+  NAME` against the last activation's backup. A failed rehearsal refuses with nothing stopped.
+- The root lock (sage-1524 finding, mos-1118). `--plan` skips `lock()` (`scripts/stack-release.sh:1046`,
+  `:1058`), so two root runs could both pass A1, and one could stop the units in the middle of the other.
+  `stack-upgrade.sh` takes `flock -n` on `/run/mosaic-stack/upgrade-<instance>.lock` before A1 and holds it
+  to the end of the run, rollback included. A second run refuses `upgrade-running` with exit 3.
+- A1 also refuses `open-activation` when any `AWAITING-UNITS` file exists or the `interrupted` set isn't
+  empty, before anything stops.
+- A migrating target refuses `migrate-required` unless `--migrate` is given (decision 96 stays process).
+- Root's step log is `/var/log/mosaic-stack/upgrade-<instance>.log`, `root:root` 0640, one line per step
+  (r6 :452-455).
+- Exit codes are r6's: 0 ok, 1 failed with the old stack running, 2 rollback-failed with the units
+  stopped, 3 refused with nothing changed.
+- duckworth-0055's notes on r6 apply here. Darkwing names how each one lands in the design or BUILD.md.
+- Root never parses output the stack's user wrote, beyond exit codes (r6 section 4's rule).
+
+### What ships: the host run sheet
+
+`docs/guides/host-run-sheet.md` is what ops-01 does on a fresh host before install, and once per host for
+enrollment. Every item names the precheck line that verifies it (I2). Where a precheck line is missing,
+I3 says so and Gosalyn adds it to I2.
+- The stack user and its home (`useradd`, `/srv/mosaic`), with no sudo and no supplementary group.
+- node pinned under `/opt`, with the gpg and sha256 checks.
+- claude for the factory profile, installed by root with `npm install --prefix
+  /opt/mosaic-stack/claude-<pin>`, plus managed settings with the autoupdater off. This replaces r6's
+  `/srv/mosaic/.local/bin` (D :124), per C2-13a's `--claude` rule.
+- bubblewrap, the AppArmor profile, `dpkg-statoverride`, the no-new-privs test, the pins, `hostcheck`, the
+  apt hook and the boot unit (r6). These are for any host that runs bwrap, so .54 gets them too.
+- The release transport: the bundle file, root's checkout made from it, and the stack user's own clone of
+  the bundle under its home (I1). Upgrade fetches each new bundle into both.
+- The machine-grant enrollment step, once per host (Gizmoduck's design r1 f6b6a04b6 section 3, as changed
+  by its review and mos-1120). Mos sent Q-O1 to ops-01 (mos-1121). Until that design is approved, this
+  item names the design and its open question and has no commands.
+- The credential slots Jason places, in one table per host, so he can do them in one sitting (mos-1118).
+  Each row gives the host, the absolute path, the file name, the mode, the owner, which profile needs it
+  and which precheck line checks it. Values never appear. The known slots, which the author checks against
+  the code and completes:
+  - the model credential, `<configDir>/secrets/claude-session.env` (Q185 for the factory, `ZAI_API_KEY`
+    for the library, C2-13a precheck)
+  - the library Console's proof file under `<home>/.config/mosaic-dev/secrets/` (C2-13a, library only)
+  - the library's Gitea token slot (C2-13b)
+  - the per-agent store under `<configDir>/secrets/agents/<business>/<agent>/` (row 199 D1), which Jason
+    fills only through `mosaic credentials issue` or, after #436, Approve
+  - the installer key under `<configDir>/secrets/hosts/<business>/<hostId>/installer` (mos-1120), made by
+    enrollment, not placed by hand
+- Console start: none by hand. I2 enables the Console unit (Q189).
+
+The run sheet is for ops-01 and Jason, so it uses commands and paths, not design prose.
+
+### Tests
+
+`stack-upgrade.test.mjs` runs the driver as the test's user against a scratch root, with fakes for
+`systemctl`, `flock`'s lock dir, I2's render and `sudo` (the fake execs the real I1 verbs as the test's
+user, r6's B1 pattern). r6's sequences 1-8 run through the driver, plus:
+- a second run while the first holds the lock refuses `upgrade-running` and changes nothing
+- an open `AWAITING-UNITS` refuses at A1 with no stop
+- a migrating target without `--migrate` refuses `migrate-required`
+- a failed rehearsal refuses with no stop
+- a confirmed upgrade records the new copy id in the args file, and a failed one leaves it as it was
+- the step log has one line per step, and nothing in it comes from the stack user's output
+
+Mutants: drop the flock, release the lock before rollback ends, skip A1's open-activation check, skip the
+rehearsal, accept `--migrate`'s absence, and write the args file before confirm.
+
+### Out of scope
+
+Running it on a host. The ops-01 PVE proof (install, upgrade to N+1, rollback) is a window with Mos's go.
+Q187 item 4 covers creating that one throwaway VM, which stays after the proof (mos-1119 item 1). Folding
+host prep into the command is #437.
+

+Filbert approves the manifest. The test file, the cli suite and every `scripts/test-*.sh` are green on

+
+## I4 hostcheck: the bwrap profile check, pins and boot unit
+
+Sage, 2026-10-21, split out of I3 (darkwing row 233 G2, sage-1650). Owner Darkwing, reviewer Filbert, gate
+owner Sage. Darkwing builds it right after I3, and it must land before the ops-01 proof.
+
+### Problem
+
+The host run sheet (I3, line 182 above) lists r6's `hostcheck` among the host items for any host that runs
+bwrap, and I3's A1 refuses `profile-drift` unless `/usr/local/lib/mosaic-stack/hostcheck.sh --check` exits 0.
+No hostcheck exists on refactor. It's r6 B2 (row 195 DESIGN.md at b7239bb66, :262-303 and :839-860), sized at
+150-200 lines of bash and 350-450 of test. That's work separate from the upgrade sequence: the root-side bwrap
+stop and a network fetch.
+
+### What ships
+
+r6 B2 as designed:
+- `case1-pins.sh` holds the pins: the profile sha256, the apparmor-profiles version and the bubblewrap pin.
+- `hostcheck.sh` covers the seven items in three modes:
+  - `--check` exits 0 or 1.
+  - `--enforce` stops bwrap: `apparmor_parser -R`, then `root:root 0700` on `/usr/bin/bwrap`. It writes
+    `/etc/mosaic-stack/DRIFT` and a `hostcheck.log` line, and exits 0.
+  - `--upstream` compares the current apparmor-profiles deb to the pin.
+- `mosaic-hostcheck.service`, a boot oneshot.
+- `case1-hostcheck.test.mjs` uses fakes for every host tool and covers r6's seven case groups and seven
+  mutants.
+
+The I3 run sheet's hostcheck item points at this row. I3's A1 and its fake don't change.
+
+### Carried from the I3 review (Filbert 29922 on #1735, sage-1727)
+
+Row 233 lands with three non-blocking notes that must be fixed before ops-01. This row takes them, and that
+widens its paths to `scripts/stack-upgrade.sh` and `packages/cli/tests/stack-upgrade.test.mjs`:
+- N1: after A5 confirms, a failed rename of the new args file calls `finish 1 args-failed` while the new copy
+  is live (`stack-upgrade.sh:280-282` at 1a1dc80ca). TOOLS.md and the run sheet define exit 1 as "the old copy
+  runs". Give this case its own exit code, add it to the exit table in TOOLS.md and the run sheet, and add a
+  test that makes the rename fail after A5 and expects the new code.
+- N4: run sheet section 3 doesn't put the pinned node's npm on root's PATH and doesn't name the `--claude`
+  path. The npm symlink `node_modules/.bin/claude` is what `case2-unit.sh:140` refuses. The sheet must name
+  the path the check accepts.
+- N5: run sheet sections 8 and 10 get their precheck lines.
+
+Filbert's N2 and N3 (no `$REPO` check, no signal handling between A2 and A5) are in DEFERRED.md, not here.

+  right to an agent that runs with strict guardrails. That agent presents
+  the final authorization for the user. Upon approval, the grant is
+  created programmatically. I see this as: User configures their PATs, API
+  tokens, authorizations within the WebUI. The agent presents the request
+  for grant with X rights for another agent. The user reviews, then clicks
+  Approve/Deny. Click of Approve fires off protected mechanical methods to
+  handle the grants on Github, Gitea, .... services as needed. The tooling
+  would need to exist and must be guarded." And "Disallowing the agents to
+  create grants autonomously is a necessary evil for better security.
+  Requiring the user to manually perform the steps is a no-fly." Q10:
+  "Agents should have tools and command access based on roles. Those roles
+  dictate the allowed tools and commands. The use of a tool or command
+  should not be raised to the user unless the system is configured with a
+  manual mode that requires user interaction. By default I want to have
+  the agents capable of running commands and tools at will within their
+  sandbox/guardrails. This allows autonomous actions by agents within
+  their lanes. Perhaps a "Trusted actions within approved guardrails"
+  methodology." And "The main agent or chief of staff would be responsible
+  for surfacing the request to the user's inbox for approval. Not all
+  agents are capable or authorized to request directly. It must follow the
+  chain of command properly." He agreed with Mos's Q10 points 3 to 6:
+  protected stack code does every step on Approve, his tokens are entered
+  in the WebUI and agents never see them, a command on the approved list
+  runs without a click and any other is refused, and he, Mos or the tester

+  other servers, etc. However, not all agents will need to have that
+  access. I envision a credential store within Mosaic Stack that works as

+  the user deletes an instance. These actions are `role.hire` and

+  within these bounds:
+  - The chief acts only in its own organization.
+  - The chief hires only role definitions that need no credentials, until
+    a later version adds credentialed roles.
+  - The chief hires only the role kinds its role file lists. Changing that
+    list is a reviewed commit.
+  - The chief hires only a role whose every action is on a fixed list of
+    plain work actions: sending messages, writing records, asking for
+    review, updating its assigned tasks, and the scope and working-push
+    actions of an assigned task. A role holding any other action, such as
+    launch, end, organization, naming, hire, review verdict or merge
+    authority, or any action added later, is never hired. So the chief
+    never hires a chief, never picks its own reviewers or merge gate, and
+    the author is never the reviewer. This holds whatever the role file's
+    list says. Adding to that list is a PRD change.
+  - The chief may set a hired instance's model and narrow its limits, and
+    nothing else about it.
+  - The user can forbid per agent. The user marks an instance so the chief
+    can't fire it, end its runs or change its model, and marks role kinds
+    the chief can't hire. Only the user changes these marks, through the

  - in Vikunja, a `bot-<business>-<role>` user per role, plus one
    read-only `bot-<business>-sync` that does all polling (lead
    decisions 52 and 58).
+
+  Since version 1.8, a token or key for a grant is made by the grant code
+  on the user's Approve (REQ-GRANT-2), not by hand. Tokens that exist stay
+  as they are.
 - **REQ-CRED-2.** A session that finds only founder credentials stops.

+Added in version 1.7:
+
+- **REQ-CRED-3.** An agent with a grant can run commands with sudo on
+  another host. The agent asks for the host credential by name. The stack
+  checks that a grant exists for that agent and that host before the
+  credential is used. The agent never sees the key or any other secret
+  value (REQ-CRED-1, REQ-VAR-2). An agent without a grant for that host is
+  refused. Not every agent gets a grant. Who grants a host credential, and
+  how, is set by the #424 design, which Jason approves.
+
+Added in version 1.8 (Q188):
+
+- **REQ-CRED-4.** An action a role definition lists within-role, and that
+  uses a grant, runs without a decision for each use only when all of
+  these hold:
+  - the definition declares the credential kind the action uses;
+  - a grant names that agent, and that host or service;
+  - for a command, the command matches the grant's allowlist. A grant
+    lists exact argv prefixes. A wildcard grant is refused;
+  - the agent's key or token for that grant is issued and not revoked.
+
+  A command off the allowlist is refused, and adding one takes a new grant
+  request (REQ-GRANT-1). An action whose definition doesn't list it
+  within-role still needs a decision for each use. Only a reviewed role
+  change adds an action to a definition. `host.sudo` routes under this
+  requirement.
+- **REQ-GRANT-1.** No agent creates or writes a grant. A grant request
+  follows the chain of command, and only the chief of staff raises it to
+  the user's inbox. Any other role that needs a grant for itself or for an
+  agent it directs asks the chief of staff, through its chain: a worker
+  role through its PM, the PM and the CTO directly. The assistant passes
+  the user's own request to the chief of staff (REQ-ASSIST-1). The request
+  names the agent, the grant method and its target, the exact rights, and
+  a rotate-by or expiry date. The chief raises one only for an agent whose
+  reviewed role definition allows that kind of credential, and the broker
+  refuses any other. A grant can't name a wildcard, a shell or an empty
+  command. The request is a decision with the action `credential.mint`, so
+  it goes to the user as a hard wait (REQ-WAIT-1). A grant whose method
+  makes an account, such as a seat's own Gitea user (Q190), is the same
+  one decision: the method in the grant says it makes an account, the
+  request names the account, and the inbox shows the account name before
+  Approve. The user's one resolution covers the account and its
+  credential, so the hard-waits list doesn't change. An `account.create`
+  raise isn't a grant request and routes as version 1.7 has it. The broker
+  checks only that the chief of staff raised the request. The chain of
+  command before that is in the messaging lists and the role contracts,
+  not a broker check. The assistant and the chief of staff are separate
+  roles. No agent holds both, and the broker refuses a claim that would.
+- **REQ-GRANT-2.** The user approves or denies each grant request in the
+  inbox. Approve is the only thing that creates a grant, and the code uses
+  a grant only when it has a matching Approve record. No agent creates a
+  grant. A grant written into the business file by hand makes nothing. Row
+  210's hand-written grants stay a test path until Vikunja #436a moves
+  `host.run` to grants made by Approve. On Approve, protected stack code
+  does every step, not an agent and not the user: it records the grant,
+  makes the key or token, installs it on the machine or creates it on the
+  service, and logs each step. On Deny nothing is made, and the denial is
+  logged. The grant methods are:
+  - machine key: a key for one agent on one enrolled host, with the
+    command allowlist of REQ-CRED-4. A host's identity comes from the host
+    side when the user approves its enrollment, never from a first
+    connection. A host user with sudo receives a grant only after the user
+    approved that user by name;
+  - Gitea: a token for one agent, and for an agent seat its own Gitea user
+    (Q190), with an expiry. The all scope and the admin scope are never
+    granted;
+  - GitHub: a grant for one agent.
+
+  The Gitea and GitHub rights units come in a later design that Jason
+  approves.
+
+  The approval binds the exact rights the user saw and the target or its
+  enrolled identity. A change to the agent, its definition, the target,
+  the target's identity or the rights after the raise voids it. An
+  approval is used once. A grant the code couldn't finish is undone at
+  once on the stack's side, so it is never used. What it left on the host
+  or service stays visible as pending until it is removed, as for a revoke
+  (REQ-GRANT-4). A new grant needs a new approval, never an automatic
+  retry. The grant code runs only on a request the user resolved. A
+  request resolved by an arbiter, the tester or any agent makes nothing. A
+  `credential.mint` decision raised before version 1.8, or without the
+  fields of REQ-GRANT-1, makes nothing when it is approved. Until the
+  Console knows the signed-in human (Vikunja #412), Approve is
+  `mosaic decide` in the CLI (REQ-DEC-3).
+- **REQ-GRANT-3.** The user enters their own personal access tokens and
+  API tokens in the WebUI, or the CLI. Only the grant code reads them, to
+  make grants. No agent ever sees a token value or a key's private half.
+  Values appear in no event, log, message, prompt or agent file, and no
+  agent can read them back (REQ-VAR-2). Until the Console knows the
+  signed-in human, they are entered through the CLI.
+- **REQ-GRANT-4.** A grant can be revoked at once by the user, by the
+  assistant for a grant in its own organization, or by the tester on a dev
+  instance (Q173). A revoke needs no decision and no new trust. It takes
+  effect at once on the stack's side, without waiting on the network, so
+  the next use is refused. Removing the key or token at the host or
+  service follows. Until that removal is done it stays visible as pending.
+  A revoke while the grant is being made stops it, and nothing it made
+  stays usable. Every revoke is logged with who made it.

+  and REQ-WAIT-2 still keeps every hard wait out of every role file.
+- **REQ-TRUST-2.** The user can put chosen actions in manual mode. The
+  organization file holds the list of actions in manual mode, empty by
+  default. While an action is on the list, every use of it by any role
+  becomes a decision for that use, raised to the user, and the action
+  waits until the user resolves it. A decision denied, or not resolved,
+  refuses the action. Each decision is used once. For a command on another

+Added in version 1.7:

+- **REQ-LAND-2.** A coder pushes its own work to its own fork. The action
+  is `git.push.remote`.
+  - What it pushes: one commit, by its oid, never a ref name. That commit
+    is the latest work commit the bus recorded for the coder's task, and
+    the coder made that push. A decision that authorizes a push names that
+    commit, and it doesn't authorize any other.
+  - Where it lands: only the branch
+    `refs/heads/<its Gitea user>/<branch>`. The host builds that name, the
+    agent never does. A push never forces.
+  - Which remote: the agent's own fork of the project's upstream. The
+    business file names the upstream, and the host never contacts it. For
+    each push the host builds the fork's address over https from the
+    upstream's host, port and repository name and the agent's own Gitea
+    user. The history check, the push and the credential match all use
+    that address. So the agent's own user owns the receiving repository on
+    every push, and the agent never names it.
+  - The host refuses an upstream on a host or port other than the agent's
+    Gitea, and an upstream the agent's own user owns. It refuses a fork
+    that is missing, empty or doesn't share the project's history. Gitea's
+    push-to-create stays off, so a push never creates a repository.
+  - Who may: the action routes under REQ-DEC-2 and is granted within-role
+    to the coder role only. No other role file grants it.
+  - Before version 1.7 the action was a hard wait under REQ-WAIT-3, so
+    each push needed a decision the human resolved, and that decision
+    named the commit.
+
+  Every push is logged with the remote, the ref, the commit and, when one
+  was given, the decision.

+- Trusted mode lets an agent run its allowed commands at will. On another
+  host, an allowed command that writes a file as root or starts a shell
+  can plant a key, and the seat sandbox doesn't confine the network, so
+  root can outlive the grant and a revoke. The allowlist narrows this. A

+| `credentials.issue` | `{agent,service,token,date}`; human only (row 199, #1697). Writes the token to `<configDir>/secrets/agents/<business>/<agent>/<service>` (0600, dirs 0700: tmp, fsync, rename), rewrites the agent's reference in the business file to `{"store":true,<rotateBy or expires>:date}`, then holds the token in memory, with no restart. Over an issued entry it is a rotate: the old value is gone from disk and memory when it returns. `service` is `gitea` or `vikunja` and the business file must already name it for the agent (`credential-unknown`). A token the bus already holds is `credential-leak`; a bad token `credential-format`; a bad date `credential-date`. Returns `{agent,verb,service,date,state}`, `verb` `issue` or `rotate`. The tester gets `tester-refused`. |
+| `credentials.revoke` | `{agent,service?,reason}`; human, or the tester (Q173). Drops the entry from memory, then unlinks a store file; a `file` or `env` reference keeps its file and becomes `store`, so a restart loads nothing. Without `service`, every kind the agent has. Returns `{agent,verb,services:[{service,state}]}`. |
+| `credentials.delete` | `{agent,reason}`; human only. `credentials.revoke` for every kind, then removes the agent's store dir; a file there other than a token is `credential-file`. While the agent or one of its threads holds a claim, `agent-running`. |
+| `hosts.status` | No args; the human, the tester or the business's chief (row 234, #1740). `[{host,address,port,user,sudo,state,hostKeys,installerFingerprint,checkedAt,hostLineLeft}]` from the `hosts` records, with host keys as fingerprints. Never a key. |
+| `hosts.check` | `{host}`; same callers. Runs the host's `list <user>` as `mosaic-installer` with the installer key and the pinned host keys, then sets `state` `ready` and `checkedAt` and writes `grant.host.checked`. A nonzero exit is `host-failed`, a record that changed during the run `host-changed`, a record with no installer key `host-not-enrolled`. |
+| `hosts.remove` | `{host}`; the human or the tester. Deletes the record, writes `grant.host.removed` and removes the installer key. A `host_grants` record for the host is `host-in-use`, a guarded event naming a host line left on the host `host-line-left`. |

+Each of the three leaves one receipt in the organization's `changes.jsonl`: the actor and a

The harness runner reads it before each turn. Writes nothing. |
