After: design draft at agents/gander/work/queue-196/DESIGN.md inventories listeners, proposes private tester HTTP and SO_PEERCRED binding, aligns the per-request principal contract with Morgana and Gizmoduck, and lists migration, tests, mutants and same-uid limits.

After: design adds eight concurrent genuine proof processes plus a racing copier, M20 swapped socket and post-helper socket survival, root-owned system ELF pinning and activation evidence, safe gid validation, cap traffic without helpers, and unchanged P19 R2 text. Mos accepted socket-only tester access (mos-1015 via sage-1363); any authenticated browser relay is a separate row. Documentation coverage checks passed. No product code, suites or live action.

After: r3 chooses startup safety revalidation, appends actual interpreter identity to bus/peercred-starts.jsonl and retains old activation evidence. Operator re-pin uses the next reviewed copy, respecting already-active refusal. Added task-by-task PLAN.md for inline implementation and independent manifest review. Documentation checks passed.

+# Row 195 build: `scripts/case1-accept.sh`
+
+Row 195 (#1693), the Case 1 install on 10.1.1.53. Design r7 at 5425ea2f3, approved by Duckworth
+(duckworth-0087, `agents/duckworth/work/row195/REVIEW-r7.md` at 58d930f89; Gitea 29962). Sage's go to build
+is sage-1817.
+
+## What this commit holds
+
+- `scripts/case1-accept.sh` (new, 100755): section 5's acceptance, F1-F11 and P1-P11.
+- `packages/cli/tests/case1-accept.test.mjs` (new): section 5's cases.
+- `docs/TOOLS.md`: the `case1-accept.sh` entry after the hostcheck entry.
+- This file.
+- `DESIGN.md`, doc-only fixes Sage named in sage-1817, with no new design round:
+  - Duckworth's N1. Section 1's human-id row cited `broker.mjs:245`; the check is `broker.mjs:321`.
+  - Row 226's state at :21 and :326. It said "unclaimed"; 226 is assigned to Gosalyn, briefed and not
+    started (sage-1814).
+  - :340 said I'd send the section 6 items to Gosalyn once 226 was claimed. I sent them on 2026-10-21
+    and Gosalyn acknowledged (gosalyn-0085), so the line now says that.
+
+Nothing else changes. No `case2-*.sh`, `stack-upgrade.sh`, `stack-release.sh`, `case1-hostcheck.sh` or run
+sheet edit, and nothing touches .53 (sage-1809).
+
+## Deviations from section 5, and choices it left open
+
+1. P4's mark is the single token `accepted Q182+Q183`. Section 5 lists `accepted Q182` and `accepted
+   Q183` as marks and gives P4 both. One line can carry one mark, and P4 is the only Q182 path, so the
+   count list has `accepted Q182+Q183` in place of `accepted Q182`.
+2. The test seam replaces `getent`. Under `--root`, the script reads `DIR/etc/passwd` and `DIR/etc/group`
+   with awk. Without it, the same helper calls `getent`. The groups of a user are its primary gid, then
+   each group whose member list names it, which is what `id -G` prints. So there is no fake `id`, and
+   the script never calls `id` for another user.
+3. P10 reads the port floor from `/proc/sys/net/ipv4/ip_unprivileged_port_start` rather than calling
+   `sysctl`, so the seam covers it the way hostcheck's item 7 is covered. There is no fake `sysctl`.
+4. There is no fake `bwrap`, `claude`, `node` or `hostcheck.sh` on PATH. The script runs each by the
+   absolute path the args file or the install names, so the test puts stubs at those paths under
+   `--root`, and the fake `sudo` runs the stack's user's commands from the tree.
+5. The args file must say `--profile factory` and name `--business`. Both are new refusals beyond
+   `stack-upgrade.sh`'s rules. A library file, or one for another business, would make F4 and F7
+   check the wrong thing. After `--`, `--port` and `--tester-port` must be numeric. The args file is the
+   only source of the ports.
+6. F8, F9 and F11 read file metadata as root: `stat`, `-L` and `find -maxdepth 1 -name '*.json'`. None
+   opens the credential. F9 parses `managed-settings.json` with the pinned node, run by root: that node
+   and that file are both root's own, installed by ops-01.
+7. F7 reads `launch.by` from `$HOME/.config/mosaic-dev/businesses/<id>.json` as the stack's user. That
+   path is `businessFilePath(id)` under the default config, which is what the unit uses. It doesn't load
+   the copy's `business.mjs` as `stack-release.sh`'s `plugins launchby` does. The user runs the whole
+   check and prints one line, and root accepts only `ok <instance> run <run>` (sage-1653: root doesn't
+   parse the user's output beyond a fixed pattern).
+8. F5 names a process claude when its argv0's basename or its `comm` starts with `claude`. The window
+   confirms this against a real role session. If the bwrap'd claude shows another name, F5 fails closed
+   and the fix is this match, not the label check.
+9. F3 and F5 run together. `talk` goes out in the background under `timeout 330`, and the `/proc` scan
+   repeats every half second until it finds a labelled pair or `talk` exits. F3's line prints first, then
+   F4, then F5, so the output keeps id order. F3 passes on exit 0 with the `sent` line and a reply line,
+   both counted on stdout only (`cli.mjs:395` and the `formatMessage` write); talk's error goes to stderr.
+12. `--claude` must match `^/[A-Za-z0-9/._+@-]+$`. The `@` is for `node_modules/@anthropic-ai/...`;
+    `stack-upgrade.sh` doesn't check `--claude` at all.
+10. F1 requires all four uids in `/proc/<MainPID>/status` (real, effective, saved, filesystem) to be the
+    user's.
+11. Evidence text the stack's user controls (talk's last line, the precheck's last line, F6's and F10's
+    `--version`) is cut to printable ASCII, one line, 200 bytes.
+
+## Tests
+
+`packages/cli/tests/case1-accept.test.mjs`, 22 tests. Every case builds a scratch host with every F check
+passing and every P check closed or accepted, then changes one thing:
+- all pass: exit 0, ids in order, each P mark, the count lines match the check lines, and the stand-in
+  credential's value appears nowhere;
+- each F check failing alone exits 1 with only its line failing;
+- F3 on exit 0 with only the `sent` line, and its evidence taking talk's stderr;
+- F1 on a failed unit and on `User=root`; F2 on healthz failing and on another pid holding the port;
+- F5 on `unpriv_bwrap (enforce)`, `bwrap//&unpriv_bwrap (complain)`, a trailing space on either label,
+  no bwrap of the user's, and passing on `comm` alone;
+- F6 on a stub that prints nothing and on a path outside `claude-<pin>`;
+- F7 on two live PM launches, a live one for another business, and no `launch.by`;
+- F8 on 0640, on another owner and on a symlink, never printing the credential;
+- F9 on a group-writable mode, another owner and a number for the flag;
+- F11 on one `*.json` under `discord/`, and passing on an empty directory;
+- each P check's unnamed mark, with the line count each fault makes: P6 one line per member, P9 one per
+  missing item; P2, P5, P10 and P11 in more than one way;
+- every P check unnamed at once still exits 0;
+- nine bad args files refuse with exit 2 before any command runs, each with its own refusal text;
+- usage errors, and a user's run without `--root`, exit 2;
+- every in-instance call goes through `sudo -u mosaic -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin`,
+  read from the fake `sudo`'s argv, and root's other `sudo` calls are exactly `-l -U mosaic`,
+  `-l -U localadmin` and the jarvis bwrap probe;
+- the host check records `--check` and never `--enforce`.
+
+## Mutants
+
+Section 5's twelve, each one exact replacement in `scripts/case1-accept.sh`, run by
+`/mnt/storage/scratch/darkwing-195-out/mutants.py` in Sage's slot (sage-1865). All twelve were killed.
+After each one the script's bytes were restored, and the final sha256 matched (`d434f15ff638...`). The
+killers below are the tests that failed in each mutant's saved log.
+
+| # | Mutant | Killed by |
+|---|---|---|
+| 1 | F1 passes on a MainPID owned by root | each F alone |
+| 2 | F2 accepts a listener on 0.0.0.0 | each F alone |
+| 3 | F3 passes without a reply | each F alone; F3 exit 0 with no reply line |
+| 4 | F5 matches a substring | F5 labels (the trailing space) |
+| 5 | F6 skips the `--version` check | each F alone; F6 stub and path |
+| 6 | F8 skips the owner check | F8 0640, owner and symlink |
+| 7 | F11 ignores `discord/` | each F alone; F11 `*.json` |
+| 8 | P1 closes on any output | P unnamed; every P unnamed |
+| 9 | P5 maps to `closed` with jarvis in docker | P unnamed; every P unnamed; P2 and P5 names docker |
+| 10 | P9 drops the jarvis item | P unnamed; P9 per item |
+| 11 | P11 accepts any `Before=` | P unnamed; every P unnamed |
+| 12 | a P check's `unnamed` sets the exit to 1 | P unnamed; every P unnamed; P10 and P11; P2 and P5; P9 per item |
+
+Mutant 1 survived the F1 variants test (a failed unit, `User=root`), because those faults fail F1 on the
+unit's state and `User=`, not on the uid line. Each F alone covers the uid line.
+
+## Pre-slot read review
+
+Since every test run is slot work, a read-only subagent traced each case through the script before the
+first slot run, executing nothing. It found four defects, all fixed in this commit:
+- The `--claude` regex had no `@`, so every run refused the args file, the real .53 one included.
+- The fake `stat` logged the args-file call, so the bad-args test's "no command ran" check would fail.
+- The P5 and P6 faults each rewrote `etc/group` from the constant, so applying both lost P5's change.
+- F3 counted stderr into its line count, so a mutant dropping the exit check survived. F3 now counts
+  stdout only, and a `sent`-only case covers the line count.
+
+## Run environment
+
+The build commit ddf7dce6c sits on base 4ced5e63d (origin/refactor when it was pushed). It was first built
+on c515273db as 4a51d392c. Row 238 then changed `docs/TOOLS.md`, so I cherry-picked the three commits onto
+4ced5e63d as `darkwing/row195-b`. `git range-diff` shows all three identical. node v26.8.1 on dragon-lin,
+every run behind my busy check and Sage's, chained with `&&`.
+
+- Step 1, sage-1829 (07:41:54Z to 07:42:05Z), TMPDIR `/tmp/dw195`:
+  `node --test packages/cli/tests/case1-accept.test.mjs`, 22 pass, 0 fail, 11.0 s.
+- Step 2, sage-1865 (08:34:27Z to 08:36:21Z), TMPDIR `/mnt/storage/scratch/tmp/r195`: the twelve mutants
+  above, all killed.
+- Step 3, the gate (08:36:21Z to 08:47:06Z), same TMPDIR, `COMPOSE_PROJECT_NAME=darkwing-r195`:
+
+| Suite | Result |
+|---|---|
+| packages/cli (`node --test tests/*.test.mjs`) | 662 pass, 0 fail, 0 skipped |
+| test-auth.sh | 15 passed, 0 failed |
+| test-conductor.sh | 17 passed, 0 failed |
+| test-config.sh | 31 passed, 0 failed |
+| test-discord.sh | 78 passed, 0 failed |
+| test-extension-package.sh | 18 passed, 0 failed |

+| test-release.sh | 14 passed, 0 failed |
+| test-task.sh | 98 passed, 0 failed |
+
+Summed: 818 node tests passed with 0 failed, and 429 selftests passed with 0 failed. The compose network
+was removed afterwards, and the sweep found no process left in the worktree, the output directory or the
+TMPDIR. This file's results are a doc-only commit on top of the build, so nothing that ran has changed.
+
+## Correction to deviation 6 (follow-up, 2026-10-21)
+
+Deviation 6 says the node F9 runs is root's own. At 37171f65b the script didn't check that. F9 ran
+`--node` as root before F10's path check, so the header's "root itself only reads" was false
+(Duckworth's N1, `agents/duckworth/work/row195/REVIEW-m1.md` at 6afcee2a5). A host installed as designed
+was safe, because `case2-unit.sh` refused a non-root-owned `--node`. Row 245 carries the fix and its
+tests: `agents/darkwing/work/queue-245/BUILD.md`.

+# Row 195 design: the Case 1 install on 10.1.1.53 (r7)
+
+Darkwing, 2026-10-21. Brief: `docs/plans/2026-10-20_hub-own-uid.md`, blob 45be7f09afc1, section "Brief: the
+Case 1 install on 10.1.1.53 (row 195)". Gitea #1693. Reviewer Duckworth, gate owner Sage. Branch
+`darkwing/row195-r7` on c515273db. r6 (b7239bb66 on `darkwing/row195`, approved duckworth-0055) is the base,
+carried unchanged as 7398b7dd7. The r6 text is in that commit and in b7239bb66.
+
+## Changes from r6
+
+Q187 (mos-1108) made install and upgrade product commands, and mos-1118 split r6 into the installer rows
+(`docs/plans/2026-10-20_installer-rows.md`). That brief says row 195 "shrinks to the factory profile's
+values and the Case 1 acceptance". So r7 is mostly a cut. What r6 designed now ships elsewhere:
+
+| r6 piece | Now | State |
+|---|---|---|
+| `stack-release.sh --units external`: `confirm`, `revert`, `gate`, `rollback --to`, external `adopt` and `status`; `stack-copy.sh check --units external` and bundle copies | row 232, I1 | landed |
+| `case1-repin.sh` (A1-A5, A2f, R1-R4) | `scripts/stack-upgrade.sh`, row 233, I3 | landed |
+| the host steps 2a, 2a', 2a'' and the window's root steps | `docs/guides/host-run-sheet.md` sections 1-10, row 233 | landed |
+| `case1-hostcheck.sh`, `case1-pins.sh`, `mosaic-hostcheck.service` (the drift stop, r6 B2) | row 240, I4 | landed c515273db |
+| the unit render, `--profile factory`, `--pm`, `--claude`, the factory serve flags, the precheck | row 230, C2-13a, I2 | landed |
+| the install as `mosaic`: bootstrap, business file, copy | row 226, C2-13b, I2, `scripts/case2-install.sh` | assigned to Gosalyn, briefed, not started |
+| `docs/guides/case1-install.md` | the host run sheet, plus section 6 of this file | |
+
+Other changes:
+
+- Claude moves under `/opt` (sage-1522, run sheet section 3). `--claude` is
+  `/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe`, root's, and root
+  installs and upgrades it. r6's `/srv/mosaic/.local/bin/claude` is gone. F6 reads the new path.
+- The args file is `/etc/mosaic-stack/dev.args` (run sheet section 7), not `case1-unit.args`. It holds
+  `--copy` too, and `stack-upgrade.sh` rewrites only that line, after confirm passes.
+- Both units are `WantedBy=multi-user.target` and start at boot (Q189, mos-1122). r6's "the Console has no
+  `[Install]`, root starts it by hand after a reboot" no longer holds.
+- The business id is stated, with the DEFERRED 240 N1 reasoning (sage-1809, sage-1813). Section 7.
+- The window can't run until row 226 lands. Sage added 226 to row 195's after list at rev 2718
+  (sage-1813). Section 6 lists what row 195 needs from 226's install.
+- The acceptance runs as root through ops-01, not as `localadmin`. `aa-status`, `sudo -l -U`,
+  `systemd-run --uid` and the hostcheck all need root. It gains four functional checks for items the run
+  sheet marks "precheck line missing" (F8-F11) and one host line (P11). Section 5.
+- The Discord row in section 2 changed. The precheck's "no Discord binding" line is C2-13b's and is
+  library-only, so for the factory it's F11 in the acceptance.
+
+What row 195 still builds: `scripts/case1-accept.sh` and its test (section 5). The rest of this file is
+inputs, the window order and the record the reviewer checks.
+
+## 0. What I checked on the host
+
+Read only, as `localadmin` over ssh, 2026-10-20 between 20:40Z and 21:51Z. Nothing in r7 touched .53
+(sage-1809). The window's first step re-reads these, since they can drift in a day: unattended-upgrades
+runs daily.
+
+| Item | 10.1.1.53 on 2026-10-20 | Needed |
+|---|---|---|
+| OS | Ubuntu 24.04.5, kernel 6.8.0-124, x86_64, 12 cores, 94 GiB, 217 GiB free on `/` | fits |
+| `mosaic` user, group, `/srv/mosaic` | absent | run sheet section 1 |
+| node | `/usr/local/bin/node` v22.22.2, root-owned | 24 or later, under `/opt` (run sheet section 2) |
+| claude | not on localadmin's PATH | under `/opt` (run sheet section 3) |
+| bwrap | absent; apt candidate `bubblewrap 0.9.0-1ubuntu0.3` | run sheet section 4 |
+| user namespaces | `kernel.apparmor_restrict_unprivileged_userns = 1`, apparmor 4.0.1, no bwrap profile loaded | run sheet section 4 |
+| profiles that name bwrap | none (`grep -rlw bwrap /etc/apparmor.d` exits 1) | hostcheck item 3 |
+| `fs.protected_hardlinks` | 1 | hostcheck item 6 |
+| `net.ipv4.ip_unprivileged_port_start` | 1024 | run sheet section 5 |
+| listeners below 1024 | 22 (sshd) and 53 (the resolver); 732 is free | the Console's port |
+| ports 7330-7333 | free | 7333 is the tester port |
+| `localadmin` | NOPASSWD sudo (#423 step 1, mos-1066, mos-1077) | ops-01's root path |
+| `jarvis` | groups sudo, docker, lxd, adm | #423 step 4 removes them (P5) |
+| unattended-upgrades | on, with the security pocket, which carries bubblewrap | the drift stop (row 240) |
+| journald | `SplitMode=uid` | the PM check reads `launches list`, not the journal (row 232) |
+
+## 1. The factory profile's values
+
+Instance `dev`, row 190's default (mos-1118 choice 4). `~` is `mosaic`'s home.
+
+| Input | Value | Who gives it |
+|---|---|---|
+| user | `mosaic`, primary group `mosaic` with no other member | fixed |
+| home | `/srv/mosaic`, 0700 | fixed |
+| config dir | `/srv/mosaic/.config/mosaic-dev` | row 190 |
+| data root | `/srv/mosaic/.mosaic-dev`, marker `{"instanceVersion":1,"name":"dev"}` | row 190 |
+| business | `mosaic-stack`, file `<configDir>/businesses/mosaic-stack.json` | fixed (section 7) |
+| profile | `factory` for `case2-install.sh`, `case2-unit.sh` and `case2-precheck.sh` | fixed |
+| roles | the factory set from `roles/`, with a chief that has a harness var | the go names the set (section 2) |
+| human id | Jason's, not `tester` (`broker.mjs:321`) | the go |
+| model credential | `<configDir>/secrets/claude-session.env`, `mosaic` 0600, one line `CLAUDE_CODE_OAUTH_TOKEN=...` | Jason places it (section 3) |
+| token slot path | none | section 2 |
+| node | `/opt/mosaic-stack/node-<v>/bin/node`, `<v>` 24 or later | the go names `<v>` and its sha256 |
+| claude | `/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe`, `<pin>` 2.1.304 unless the go names a newer one | the go |
+| PM | on (`--pm`) | fixed |
+| Console | `--port 732` on 127.0.0.1, with the unit's `CAP_NET_BIND_SERVICE` | fixed |
+| tester | `--tester-port 7333` on 127.0.0.1 (P10) | fixed |
+| board | none | fixed |
+| release | a git bundle of `refs/heads/refactor` and the 40-hex commit (run sheet section 6) | the go names both and the bundle's sha256 |
+
+The args file. `/etc/mosaic-stack/dev.args`, `root:root` 0644, one argument per line (run sheet section 7):
+
+```
+--profile
+factory
+--user
+mosaic
+--home
+/srv/mosaic
+--business
+mosaic-stack
+--copy
+<40-hex commit>
+--node
+/opt/mosaic-stack/node-<v>/bin/node
+--claude
+/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe
+--pm
+--
+--port
+732
+--business
+mosaic-stack
+--tester-port
+7333
+```
+
+`case2-unit.sh` takes exactly these before `--` (`scripts/case2-unit.sh:54`), and `stack-upgrade.sh`
+refuses `args-unreadable` on anything else (`scripts/stack-upgrade.sh:126-148`). The factory profile
+refuses the preview trio, `--send` and the proof pair (`case2-unit.sh:169`). .53 has no proxy, and Jason
+reaches the Console with `ssh -L` (sage-1451 Q3). Changing a serve flag is a re-install with its own go,
+not an upgrade.
+
+Why the port is 732 (r6, mos-1101 item 5). Role sessions share the host's network namespace
+(`packages/seat/src/sandbox.mjs:67`), so while the Console is down a session could bind a port above the
+floor and answer in its place. Below 1024 only the Console unit can bind, through its capability. The
+tester port can't go below 1024 (`packages/webui/src/cli.mjs:33`), so P10 records it.
+
+PATH for `mosaic`'s steps. `sudo -u mosaic -H` resets PATH to sudo's `secure_path`, which finds
+`/usr/local/bin/node`, v22. So every `mosaic` step runs as
+`sudo -u mosaic -H env PATH=/opt/mosaic-stack/node-<v>/bin:/usr/local/bin:/usr/bin:/bin ...`, the list
+`case2-unit.sh` renders as the units' PATH. `stack-upgrade.sh` builds it from the args file's `--node`.
+
+## 2. Where Case 1 differs from Case 2
+
+| Case 2 (library) | Case 1 (factory) | Reason |
+|---|---|---|
+| business file with the library mapping | `mosaic-stack` with no `library` key. The precheck refuses a library project under `factory` (`profile-library-business`, `case2-precheck.sh:127-128`) | the factory has no books repo |
+| `bean`, `chet`, persona vars and files, specialists | the factory roles from `roles/`, with a chief that has a harness var | the go names the set. I haven't read Jason's live business file and won't. The acceptance needs only the chief (F3); a chief with no harness var answers `no-route`. The human adds roles later with `instances.set`, no new row |
+| token slot `library-gitea` | none | the factory's per-agent git identity is row 199's credential store (Megavolt, #1697). Until it lands, git work stays on dragon-lin (Q182) |
+| `bus.tester` off | on; the precheck refuses it off under `factory` (`case2-precheck.sh:135`) | the acceptance and the Q173 test system need the tester |
+| persona modes and digests, `library.sync`, `library.status` | skipped | no persona files, no library (C2-13b brief, `factory` profile) |
+| `ZAI_API_KEY` in `claude-session.env` | not checked; the file holds `CLAUDE_CODE_OAUTH_TOKEN` | no instance has provider `zai` (run sheet section 9) |
+| no Discord binding (C2-13b, library only) | none either. F11 checks that `<dataRoot>/discord/` holds no binding | the factory's connector stays on dragon-lin. Two connectors on one bot token would split its events |
+| the claude marker prompt | runs, since the chief's harness is claude-code | |
+| serve flags: preview trio, `--send`, proof pair | `--port 732`, `--business mosaic-stack`, `--tester-port 7333` | no proxy on .53 |
+| bus: no `--pm`, no `MOSAIC_CLAUDE_BIN` | `--pm`, and `Environment=MOSAIC_CLAUDE_BIN=<--claude>` | the PM dispatches the factory's work; without the path the bus finds no claude on the unit's PATH |
+| Console proof file (run sheet section 9, .54) | none | no proof pair |
+
+All of these are inputs to the landed scripts. Row 230 implemented the four factory items r6 asked for
+(serve flags, `--pm`, `--claude`, row 190's tokens), and nothing in them hardcodes a Case 1 value.
+
+## 3. Model access
+
+Q185: Case 1 uses the account the factory uses today, the Claude subscription behind dragon-lin's
+`claude-session.env`. No script copies that file and none reads its value. In the window, Jason, or the
+person he names under the Q173 secrets rule, makes a credential for .53 from that account and writes it
+to `/srv/mosaic/.config/mosaic-dev/secrets/claude-session.env` as `mosaic`, mode 0600 (run sheet
+section 9). Nobody prints it. The check is `stat -c '%U %a %F' PATH` only (F8).
+
+The bus unit reads it through `EnvironmentFile=-` (`case2-unit.sh:243`). The leading `-` means a missing
+file doesn't stop the bus, so the chief's first launch would fail instead. The window places the file
+before the units start (section 6, W9), and the precheck's claude marker prompt then proves it works
+without printing it.
+
+Quota: the factory on dragon-lin and on .53 share one subscription. Q185's "use existing" accepts that.
+The pi harness stays off on .53 until P19 #383 settles (mos-0865). The business file names claude only.
+
+## 4. Upgrade, rollback and backup on .53
+
+All three are `scripts/stack-upgrade.sh` (row 233), run as root by ops-01 from `/root/mosaic-stack` at the
+reviewed commit. Usage, exits and the step log are in `docs/TOOLS.md`, "Root's upgrade driver", and run
+sheet section 6.
+
+| Action | Command | Who | Go |
+|---|---|---|---|
+| upgrade | `stack-upgrade.sh upgrade --instance dev --bundle /srv/mosaic/incoming/<sha>.bundle --sha <sha>` after run sheet section 6's per-upgrade lines | ops-01 | Mos per run; `--migrate` also needs Jason present (decision 96) |
+| rollback | `stack-upgrade.sh rollback --instance dev --to <copy> [--restore <ACT> [--events N]]` | ops-01 | Mos per run. Mos or Sage picks `<copy>` from `stack-release.sh status mosaic-stack --units external`, read as `mosaic`. The plan refuses unless it is the previous distinct copy |
+| backup of the store | A3's `backup_store` into `<dataRoot>/backups/stack/<ACT>`, inside every upgrade | the driver | the upgrade's |
+| rehearsal | `stack-release.sh rehearse` against the log's newest backup, before anything stops, on `--rehearse-port`, default 7339, which section 0 found free | the driver | the upgrade's |
+| backup of the VM | a PBS backup of VM 1008 before the install window and before any `--migrate` | ops-01 | the window's go (Q182, Q183: agents keep PBS) |
+
+Three .53 specifics:
+
+1. The first upgrade after install needs `--no-rehearsal` in its go. The install's adopt takes no backup,
+   so the log records none, the rehearsal exits 3 (`no-backup`), and the driver goes on only with the
+   flag (`stack-upgrade.sh:323-324`). Every later upgrade refuses the flag (`rehearsal-required`).
+2. Exit 5 (`args-failed`): the new stack is live and confirmed, but `dev.args` still names the old copy.
+   ops-01 moves the file the result line names into place with `mv -f`, and nothing else (run sheet
+   section 6).
+3. Exit 2 leaves both units stopped and the activation open. ops-01 sends Mos the exit and the last
+   lines of `/var/log/mosaic-stack/upgrade-dev.log`, and Jason or Mos settles it with `confirm` or `revert`
+   as on dragon-lin. A unit that doesn't stop within `--timeout` ends here on purpose (A2f's
+   `stale-start`, duckworth-0055 N1, now in run sheet section 6).
+
+The store backup doesn't hold the config dir or the credential. PBS backups of VM 1008 hold the whole disk,
+the credential included (P4). A restore swaps only the store and leaves `claude-session.env` in place.
+
+Re-install, for a serve flag or role change, is not an upgrade. It needs its own go and runs: stop the
+Console, then the bus; rewrite `dev.args` with the same `--copy`; `case2-unit.sh` with it; both units start
+again from the render. Row 230 N1 (webby-0046) holds here: a re-render with the units running leaves each on
+its old copy, so ops-01 stops both first. `stack-upgrade.sh` already stops both before it renders.
+
+## 5. Acceptance: `scripts/case1-accept.sh`
+
+New in this row. ops-01 runs it as root on .53, from `/root/mosaic-stack`:
+
+```
+case1-accept.sh --business mosaic-stack --args /etc/mosaic-stack/dev.args --claude-pin <pin> --node-pin <v>
+```
+
+It reads the user, home, node, claude and ports from the args file and refuses (exit 2) when that file
+fails `stack-upgrade.sh`'s rules. Every check inside the instance runs as
+`sudo -u mosaic -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin`. It changes nothing on the host
+except what F3's message writes to the store. It prints one line per check, `<id> <path> <mark>
+<evidence>`, then a count of each mark. Marks: `closed`, `accepted Q182`, `accepted Q183`, `accepted
+mos-1096`, `accepted mos-1101`, and `unnamed`, which means "not named in Q182, Q183 or a Mos ruling".
+It exits 1 when any F check fails and 0 otherwise. A P check never changes the exit. Each `unnamed`
+line goes to Mos, who takes it to Jason (R8 N1). Duckworth reads the whole output.
+
+It prints no value from `claude-session.env` and never opens it.
+
+Functional checks. Any failure fails the row:
+
+| Id | Check | How |
+|---|---|---|
+| F1 | the units run as `mosaic` | for `[email protected]` and `mosaic-webui.service`: active, `User=mosaic`, and the uid in `/proc/<MainPID>/status` is `mosaic`'s |
+| F2 | the Console answers on 127.0.0.1:732 only | `curl -fsS http://127.0.0.1:732/healthz` succeeds, and `ss -Hltnp` shows 732 bound to 127.0.0.1 only, by the Console's MainPID. Jason reaches it with `ssh -L 7332:127.0.0.1:732 [email protected]`. A LAN listener waits for Q175 SSO (sage-1451 Q3) |
+| F3 | one tester message gets a reply | as `mosaic`: `mosaic talk chief <marker> --business mosaic-stack --tester --wait 300`. A stored reply to the marked message passes. The inbox shows decisions only, so it isn't used |
+| F4 | the precheck passes | `case2-precheck.sh --business mosaic-stack --profile factory` as `mosaic` exits 0 |
+| F5 | a role session runs under bwrap with the profile | while F3's reply is pending: a `/usr/bin/bwrap` process owned by `mosaic` has a claude child. Its `/proc/<pid>/attr/current` equals `bwrap (enforce)` and the child's equals `bwrap//&unpriv_bwrap (enforce)`, exact strings after the trailing newline is cut |
+| F6 | claude is the pin | the args file's `--claude` path sits under `/opt/mosaic-stack/claude-<pin>/`, and its `--version` as `mosaic` prints `<pin> (Claude Code)` |
+| F7 | the PM run is live | `launches list --json` as `mosaic` has exactly one live entry for the PM's instance (`launch.by`), the check `confirm` runs |
+| F8 | the credential's file | `stat -c '%U %a %F'` on `claude-session.env` reads `mosaic 600 regular file`, and it isn't a symlink. Run sheet section 9 marks this "precheck line missing" |
+| F9 | the autoupdater is off | `/etc/claude-code/managed-settings.json` is `root:root` 0644 and its `env.DISABLE_AUTOUPDATER` is `"1"`. Run sheet section 3 marks this "precheck line missing" |
+| F10 | node is the pin | the args file's `--node` is `/opt/mosaic-stack/node-<v>/bin/node` with `<v>` the `--node-pin`, and its `--version` prints `<v>`. Run sheet section 2 marks this "precheck line missing" |

+
+Host paths. These report and never fail the row:
+
+| Id | Path | Mark | Evidence |
+|---|---|---|---|
+| P1 | `mosaic` has sudo | closed only when `sudo -l -U mosaic` prints "is not allowed to run sudo"; any other output is unnamed | the `sudo -l` result |
+| P2 | `mosaic` has supplementary groups or a key | closed when `id -G mosaic` is one entry and `~mosaic/.ssh/authorized_keys` is absent or empty | `id`, file state |
+| P3 | `localadmin` NOPASSWD sudo, reached with the dragon-lin key | accepted Q183 | `sudo -l -U localadmin` |
+| P4 | root on pve over VM 1008, and PBS backups that hold `/srv/mosaic` with the credential | accepted Q182 and Q183 | a fixed line; the script can't see pve |
+| P5 | `jarvis`, which runs Hermes, reaches `/srv/mosaic` through sudo, docker or lxd | closed when `jarvis` is in none of the three; unnamed otherwise. #423 step 4 removes all four groups before the install (mos-1091 4c) | `id jarvis` |
+| P6 | other members of sudo, docker, lxd | closed when sudo holds only `localadmin` and docker and lxd are empty; each other member is its own unnamed line | `getent group` lines |
+| P7 | a file under `/etc/sudoers.d` naming `mosaic` | closed when none | file names |
+| P8 | the Console or tester reachable from the LAN | closed when 732 and 7333 are bound to 127.0.0.1 only, each by the Console's MainPID, and nothing listens on 7331 | listener table |
+| P9 | a user namespace through `/usr/bin/bwrap` | accepted mos-1096 only while all eight hold, unnamed otherwise: hostcheck items 1 to 6, read from `/usr/local/lib/mosaic-stack/hostcheck.sh --check`'s own `ok N` lines (item 7 is P10's floor); `sudo -u jarvis /usr/bin/bwrap --version` fails with "Permission denied"; `getent group mosaic` lists no member and no other account has its gid. F5 adds the label of a real role session | the hostcheck lines and each item |
+| P10 | a session binds the tester port 7333 while the Console is down | accepted mos-1101 while the port floor is above 732 and 7333 is held by the Console's MainPID | the floor, the owner pid |
+| P11 | the boot check runs before the bus | closed when `mosaic-hostcheck.service` is enabled and `systemctl show -p Before` on it names `mosaic-bus@<business>.service` for the args file's business; unnamed otherwise (section 7) | the `Before=` value |
+
+P9 reads hostcheck's output, which root's own script prints, by matching `^ok [1-6] ` lines. It runs `--check` only,
+never `--enforce`, so the acceptance can't close bwrap.
+
+Tests, in `packages/cli/tests/case1-accept.test.mjs`. The script takes a test seam, `--root DIR`, for
+`/proc`, `/etc`, `/srv/mosaic` and `getent`, and refuses it when run as root, as the hostcheck does. Fake
+`systemctl`, `curl`, `ss`, `sudo`, `bwrap`, `sysctl`, `stat`, `claude`, `node` and `hostcheck.sh` on PATH.
+Nothing reaches .53 or dragon-lin's live state, and no test reads a real credential. Cases:
+- every check passing exits 0, with the counts matching the lines;
+- each F check failing alone exits 1 with its line;
+- F5 fails on `unpriv_bwrap (enforce)`, `bwrap//&unpriv_bwrap (complain)` and a trailing space;
+- F6 fails on a stub `claude.exe` that prints nothing and on a path outside `claude-<pin>`;
+- F8 fails on mode 0640, on another owner and on a symlink, and the stand-in credential's value never
+  appears in the output;
+- F11 fails on one `*.json` under `discord/`;
+- each P check in each of its marks: P1 with output that grants nothing but lacks the refusal text
+  (unnamed), P9 unnamed once for each item missing, P10 unnamed with the floor at 700 and with 7333 held
+  by another pid, P11 unnamed with `Before=` naming another business;
+- every P check `unnamed` still exits 0;
+- a bad args file refuses with exit 2 before any check;
+- every in-instance call goes through `sudo -u mosaic -H env PATH=<node dir>:...`, read from the fake
+  `sudo`'s recorded argv;
+- the hostcheck fake records `--check` and never `--enforce`.
+
+Mutants, each killed by a named case:
+1. F1 passes on a MainPID owned by root.
+2. F2 accepts a listener on 0.0.0.0.
+3. F3 passes without a reply.
+4. F5 matches a substring.
+5. F6 skips the `--version` check.
+6. F8 skips the owner check.
+7. F11 ignores `discord/`.
+8. P1 closes on any output.
+9. P5 maps to `closed` with `jarvis` in docker.
+10. P9 drops the jarvis item.
+11. P11 accepts any `Before=`.
+12. A P check's `unnamed` sets the exit to 1.
+
+## 6. The .53 window
+
+Nothing in this row touches .53 (sage-1809). Every root step below is ops-01's, over
+`ssh [email protected]` with `sudo`, and waits on a Jason decision (mos-1086). The window needs:
+- row 226 landed;
+- Jason's or Mos's go naming the commit, the bundle's sha256, the node and claude pins, the role set and
+  Jason's human id;
+- a backup first;
+- a STATE report after.
+
+| # | Step | Runs as | Source |
+|---|---|---|---|
+| W0 | re-read section 0's items; stop on any change and report it | `localadmin`, read only | section 0 |
+| W1 | PBS backup of VM 1008 | ops-01 on pve | section 4 |
+| W2 | the stack's user and home | root | run sheet 1 |
+| W3 | node under `/opt` | root | run sheet 2 |
+| W4 | claude under `/opt`, managed settings | root | run sheet 3 |
+| W5 | bubblewrap, the profile, the statoverride, the no-new-privs test, the drift stop; `hostcheck.sh --check` exits 0 with item 7 at 1023 | root | run sheet 4 |
+| W6 | the port floor (read) | root | run sheet 5 |
+| W7 | the bundle, root's checkout at `<sha>`, `mosaic`'s clone | root, then `sudo -u mosaic -H` | run sheet 6 |
+| W8 | `case2-install.sh --profile factory` with section 1's inputs: bootstrap, the business file, roles, human id, the copy | `sudo -u mosaic -H env PATH=...` | row 226 |
+| W9 | place `claude-session.env` | Jason, or who he names | run sheet 9, section 3 |
+| W10 | write `dev.args` (section 1); `case2-unit.sh` from it, which enables both units and starts the bus, then the Console | root | run sheet 7, 10 |
+| W11 | `case2-precheck.sh --business mosaic-stack --profile factory` exits 0; `hostcheck.sh --check` exits 0 with item 7 at 732 | `mosaic`; root | row 230, 240 |
+| W12 | `stack-release.sh adopt mosaic-stack --units external`, unless row 226's install does it | `sudo -u mosaic -H` | row 232 |
+| W13 | `case1-accept.sh` (section 5); the output to Duckworth, then Mos confirms | root | this row |
+| W14 | STATE report to Mos | ops-01 | brief |
+
+Install rollback, any step before W13 passes. Stop and disable both units, remove their files and
+`dev.args`, then the run sheet's rollbacks for sections 4, 3 and 2 in that order. Removing the user and
+home (`userdel -r mosaic`) needs its own Mos go, since it deletes the home. W1's backup covers the rest.
+
+What row 195 needs from row 226. Row 226 is assigned to Gosalyn, briefed and not started, so I'm listing what the window
+needs from its design, not designing it:
+
+1. `--profile factory` writes the business file with `bus.tester` on and no `library` key, and the roles
+   the go names.
+2. It writes no token slot and no persona files (its brief says so).
+3. It runs before the unit render, since the copy must exist for `case2-unit.sh --copy`, and it starts no
+   unit.
+4. Who writes `dev.args`. The C2-13b brief says the install doesn't write unit files, and the run sheet
+   says "I2's install writes it". `mosaic` can't write `/etc/mosaic-stack`. So either root's part of I2
+   writes it, or ops-01 writes it from section 1 at W10. Either works for row 195. The file's content is
+   fixed above.
+5. Whether it runs `adopt`. If it doesn't, W12 does.
+
+I sent these to Gosalyn on 2026-10-21 (gosalyn-0085 acknowledged), and the run sheet takes whichever answer 226 gives.
+
+## 7. The business id
+
+.53's business id is `mosaic-stack` (sage-1813). It appears in:
+- the args file, twice;
+- the bus unit `[email protected]`;
+- the business file name;
+- `case1-accept.sh --business`.
+
+The landed boot unit `packages/cli/systemd/mosaic-hostcheck.service` has
+`[email protected]`. So at boot the drift stop runs before .53's bus, and DEFERRED 240
+N1 (da3051ccc: `After=mosaic-hostcheck.service` in `mosaic-bus.service.in`) doesn't bind this row.
+
+If a go ever names another id for .53, the window stops before W8, and the N1 fix lands first as its own
+reviewed row. P11 is the check on the host. It reads `unnamed` when the boot unit's `Before=` doesn't
+name the installed bus.
+
+DEFERRED 240 N2 (the apt hook goes in before the first `--check`) is a run sheet order note. This row
+doesn't edit the run sheet, so it stays deferred.
+
+## 8. Rulings this design rests on
+
+- sage-1451: Q1 system units; Q3 the Console on 127.0.0.1 with `ssh -L`; Q4 a rebase goes to a new branch
+  name (#426(a), mos-1086).
+- mos-1091, mos-1096, mos-1098, mos-1101: the bwrap path, its profile and P9; the port squat and P10; .53
+  runs the PM. Their r6 sections stand, and rows 232, 233, 240 and 230 implemented them.
+- mos-1108 (Q187) and mos-1118: the installer rows and the scope cut. mos-1122 (Q189): both units start at
+  boot.
+- sage-1522: claude under `/opt`, root-owned.
+- sage-1809: no step on .53, root steps named and left to ops-01, the business id stated.
+- sage-1813: 226 in the after list (rev 2718); the id is `mosaic-stack` and 240 N1 doesn't apply.
+- Q185: the factory's model account. Q173: credentials placed by Jason or his named person.
+
+## 9. Manifest (planned)
+
+- `scripts/case1-accept.sh` (new), mode 100755.
+- `packages/cli/tests/case1-accept.test.mjs` (new). Section 5's cases and mutants.
+- `docs/TOOLS.md`: a `case1-accept.sh` entry with usage, marks and exits, beside the hostcheck entry.
+- `agents/darkwing/work/queue-195/BUILD.md` (new): run environment, the mutant results, deviations.
+- No change to `case2-*.sh`, `stack-upgrade.sh`, `stack-release.sh`, `case1-hostcheck.sh` or the run
+  sheet. Two follow-ups stay out of this row:
+  - row 230 r2 N1. The "still on copy" line reads the id from the unit file. On .53 neither the install
+    nor `stack-upgrade.sh` reaches that line, since both start from stopped units.
+  - DEFERRED 240 N2.
+- No change to `~/.mosaic-dev`, `~/.config/mosaic-dev`, dragon-lin's units or `~/.mosaic`.
+
+Gate: Duckworth approves this design, then the manifest; the cli suite and every `scripts/test-*.sh`
+green on Sage's gate; section 5's twelve mutants killed in a slot Sage grants.

+# 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.

+
+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.

+Candidate a0ffabc3f on `darkwing/row232-r1`, run by `~/darkwing-scratch/r232/gate.sh`: the cli suite, then

+
+`~/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.

+## 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
+8fede5fc6 with no conflict, then this section. No code or test changed.
+
+- `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`).
+- The seven code, test and doc paths other than the README hash the same as in manifest 7a3b4ea1, which
+  Filbert approved in round 1: `docs/TOOLS.md`, `packages/cli/tests/stack-copy.test.mjs`,
+  `packages/cli/tests/stack-release-external.test.mjs`, `packages/cli/tests/stack-release-fixture.mjs`,
+  `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.
+
+Follow-up, doc-only (sage-1673): `scripts/case2-unit.sh:108` and `scripts/case2-precheck.sh:157` cite
+`scripts/stack-copy.sh:8` and `:22` for `COPIES` and `copy_root`. With this row those lines are `:10` and
+`:26`. Only comments are affected and no test reads them. Row 233 doesn't touch those scripts, so the fix
+goes on the #1732 carry list.

+- `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`.

+## 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 |

+
+## 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.
+

+`stack-release.sh`, so it joined the three named in the plan.

+| `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`.

+`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

+Sage's slot, with a sweep for a leftover `sleep` afterwards.

+# Row 240 (I4): root's host check, its pins and the boot unit
+
+Brief: `docs/plans/2026-10-20_installer-rows.md` section I4, blob `4a5a65020f00` (commit b00d7d94d, rev 2665,
+the pin row 240 carries; the I3 carry items came in with it). Sage split it out of I3 (sage-1650). Gitea #1746, Vikunja P19 #432. Owner Darkwing, reviewer Filbert, gate owner Sage.
+Design: row 195 DESIGN r6 B2, `agents/darkwing/work/queue-195/DESIGN.md` at b7239bb66, :262-303 (the script,
+the three callers) and :839-860 (files, test cases, mutants). Where the brief and r6 differ, the brief wins.
+
+## Files
+
+Drafted on `darkwing/row240-r1` from d99166ade (row 233's candidate) while row 233's gate ran, then applied
+as one patch onto row 233's landing, 57f59e0c3, on `darkwing/row240-r2` (sage-1753). It applied cleanly; between
+the two bases the only change on this row's paths is 233's N1 test fix in `stack-upgrade.test.mjs`. Row 234
+then landed as c771a36f4 on 57f59e0c3. Sage preferred that the gate run with it in the tree (sage-1773), so both
+commits were picked onto c771a36f4 as `darkwing/row240-r3`. That was a clean pick: the 42 paths changed from
+57f59e0c3 to c771a36f4 share none with this row's 9.
+
+- `scripts/case1-pins.sh` (new, 0644): `PIN_PROFILES_VERSION`, `PIN_PROFILE_SHA256`, `PIN_BUBBLEWRAP_VERSION`,
+  r6 section 0's values.
+- `scripts/case1-hostcheck.sh` (new, 0755): the seven items and `--check`, `--enforce`, `--upstream`.
+- `packages/cli/systemd/mosaic-hostcheck.service` (new): the boot oneshot.
+- `packages/cli/tests/case1-hostcheck.test.mjs` (new, 16 tests). The cli suite's `tests/*.test.mjs` glob picks
+  it up.
+- `docs/guides/host-run-sheet.md` section 4: the install lines that replace "Install them from row 240's run
+  sheet lines once it lands", plus rollback, drift recovery and `--upstream` before a re-pin window. Sections
+  3, 6, 8 and 10 for the I3 carry items below.
+- `scripts/stack-upgrade.sh` and `packages/cli/tests/stack-upgrade.test.mjs`: I3 N1 below.
+- `docs/TOOLS.md`: a new subsection "Root's host check (`scripts/case1-hostcheck.sh`, row 240)" after the
+  upgrade driver's.
+
+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.
+
+## The brief, item by item
+
+| Brief line | Where |
+|---|---|
+| 247 `case1-pins.sh` holds the three pins | `scripts/case1-pins.sh`; the pins test checks the values against r6's |
+| 248-249 seven items, `--check` exits 0 or 1 | `items()` and the final dispatch; the check tests |
+| 250-251 `--enforce`: `apparmor_parser -R`, `root:root 0700`, `DRIFT`, a log line, exit 0 | `enforce()` and `stop_bwrap()`; the four enforce tests |
+| 252 `--upstream` compares the current deb to the pin | `upstream()`; the upstream test |
+| 253 the boot oneshot | `mosaic-hostcheck.service`; the boot unit test |
+| 254-255 fakes for every host tool, r6's seven case groups, seven mutants | the test file; Tests and Mutants below |
+| 257 the I3 run sheet item points here | run sheet section 4 |
+
+## 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.

+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).

+# Row 245 build: Duckworth's N1-N3 on `scripts/case1-accept.sh` (row 195 follow-up)
+
+Duckworth approved row 195's manifest round 1 (duckworth-0088, `agents/duckworth/work/row195/REVIEW-m1.md`
+at 6afcee2a5) with three notes that don't block. Row 195's code landed as b65014647, and the notes are in
+`docs/plans/DEFERRED.md` (d6cff0cdd). Row 245 carries them: brief `docs/plans/2026-10-20_hub-own-uid.md` §
+"Row 195 follow-up" at 62ddc96cc, owner Darkwing, reviewer Duckworth, gate owner Sage (sage-1923).
+
+The branch is `darkwing/row245`, on 62ddc96cc. Its first commit is a cherry-pick of `darkwing/row195-n1`
+1e3c4767c, which was written on 37171f65b and never run. The script, test and TOOLS.md blobs are the same
+as in 1e3c4767c, and none of those paths changed between 37171f65b and 62ddc96cc.
+
+## What changes
+
+N1. F9 ran `$ROOT$NODE` as root (`case1-accept.sh:298` at 37171f65b) before F10 checked that `--node` is
+the pinned path. Duckworth offered two fixes: F9's parse through `AS_USER`, or F10's path check first. I
+took the path check, plus one more:
+- F9 now runs node only when `--node` equals `/opt/mosaic-stack/node-<--node-pin>/bin/node`.
+- Then `not_root_only` walks from that file up to `/`. Each entry must be the running user's (root's on the
+  host) with no group or other write, the rule `case2-unit.sh` `root_only` applied when it rendered the
+  units. A symlink fails it, because its mode is 777. The first entry that breaks the rule goes in the
+  evidence.
+
+I didn't run the parse through `AS_USER`. That would hand a check about a root file to the stack's user,
+and a process running as `mosaic` shares that node's uid. Whether it could change what node prints then
+turns on the host's ptrace setting, and the root-only check doesn't depend on that. Sage agreed in
+sage-1877. Rechecking ownership costs one loop and doesn't depend on
+how the host was installed.
+
+N2. The header (:9-15) and the `docs/TOOLS.md` entry now list what root runs: `systemctl show` and
+`is-enabled` (F1, P11), `curl` on the loopback healthz (F2), `sudo -l` (P1, P3), `sudo -u jarvis bwrap
+--version` and `hostcheck.sh --check` (P9), and node for F9 under the rule above.
+
+N3. F6 matched `--claude` by prefix, so `/opt/mosaic-stack/claude-<pin>/../claude-2.0.9/...` passed the
+path check. F6 now fails on any `..` segment, before it runs `--version`. F10 compares for equality, so
+it needed no change.
+
+Row 195's BUILD.md gets a correction entry for deviation 6. Row 195's DESIGN.md is unchanged. Its "either
+works" wording at `DESIGN.md:336-338` is superseded by gosalyn-0087 (root writes `dev.args` at W10), and
+it stays in place: an approved design isn't edited (sage-1877).
+
+## Tests
+
+`packages/cli/tests/case1-accept.test.mjs`:
+- The node stub touches `node-as-root` in the state directory when something runs it outside the fake
+  `sudo` (which sets HOME to the stack's home). `host()` sets the node file's directories and the scratch
+  root to 0755, so the umask can't fail F9.
+- "every check passing" also asserts that root ran the pinned node.
+- New: "F9 won't run --node as root off the pin path or with a writable directory above it". Another node
+  path fails F9 and F10, with no root run. A group-writable `bin/` and a symlinked node each fail F9
+  alone, with the bad path in the evidence and no root run.
+- The F6 test gains a `..` case: a path under `claude-<pin>/` by prefix that names 2.0.9's binary, which
+  prints the pin. F6 alone fails, with "has a .. segment".
+
+That makes 23 tests. All 23 pass on Sage's slot (results below).
+
+## Mutants
+
+The twelve from row 195 still apply, unchanged. These four are new, each one exact replacement:
+
+| # | Mutant | Expected killer |
+|---|---|---|
+| 13 | F9 runs any `--node` (the pin check becomes `true`) | F9 won't run (another node) |
+| 14 | F9 skips the ownership walk (`bad=""`) | F9 won't run (writable `bin/`, symlink) |
+| 15 | `not_root_only` checks only the file, not the directories above it | F9 won't run (writable `bin/`) |
+| 16 | F6 accepts a `..` segment | F6 stub, path and `..` |
+
+The brief's gate asks for a mutant for each of N1 and N3. Mutants 13-15 are N1's, and 16 is N3's.
+
+## Slot plan
+
+Same shape as row 195's steps, on this row's tip: the single test file, then the sixteen mutants, then
+the gate (the cli suite and every `scripts/test-*.sh`), each behind the busy checks and chained with
+`&&`. The scripts are in `/mnt/storage/scratch/darkwing-245-out/`.
+
+## Slot results (grant sage-1961, 2026-10-21)
+
+All three steps ran on 0590a29fc with node v26.8.1, launched from `/`. Both busy checks were CLEAR
+before each step.
+
+- Singles, 11:27:46-11:27:59Z: `case1-accept.test.mjs` passed 23, failed 0.
+- Mutants, 11:28:10-11:31:20Z: all 16 killed, each with exit 1. The runner restored the script, and
+  its sha256 875bb5b7 matches the committed blob. Rows 1-12 died as in row 195. 13, 14 and 15 died on
+  "F9 won't run --node as root off the pin path or with a writable directory above it". 16 died on
+  "F6 fails on a stub that prints nothing, on a path outside claude-<pin> and on a .. segment".
+- Gate, 11:31:20-11:42:51Z: the cli suite passed 664, failed 0, skipped 0. Every `scripts/test-*.sh`
+  exited 0: auth 15, conductor 17, config 31, discord 78, extension-package 18, foundation 44,
+  land-work 86, queue 28 (its node part 156/0), release 14, task 98. That's 429 selftests, none failed.
+- Afterwards no process had its cwd in the worktree, the out dir or TMPDIR, and the
+  `darkwing-r245_default` network was gone.

+## Names: r6 against section 7
+
+r6's `grant.*` and `host.enroll.*` names are `body.action` values on `action.allowed` events, not event

+
+| r6 | This row |
+|---|---|

+| `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 235 build: machine grant row b (#436, Gitea #1741)
+
+Brief: `docs/plans/2026-10-20_host-credentials.md`, "Machine grant row b: raise binding, executor,
+reconcile and revoke". Design r6 f9039682e. Built on row 234's landing c771a36f4 (sage-1775), branch
+gizmoduck/row235-b. Line numbers below were read on b0320d395, whose src files are byte-identical to the landing's.
+
+## Squash onto 4ced5e63d (sage-1812, sage-1831)
+
+Steps 1-6 were six local commits on c771a36f4 (gizmoduck/row235-b, tip f9fff4300). Sage named
+4ced5e63d as the base, so this branch, gizmoduck/row235-c, holds one commit on it: the diff
+c771a36f4..f9fff4300 applied with `git apply --index`. N10 is in that commit. N12 needs no change,
+because row b doesn't touch schema.sql.
+
+Rows 240, 228 and 238 landed between c771a36f4 and 4ced5e63d and changed 18 paths. One of them is
+also mine:
+
+- `packages/cli/README.md`. Row 228 (86249ac55) changed the session credential paragraphs at about
+  lines 432 and 706. My hunk adds three lines on `hosts revoke` and `hosts sweep` at about line 1052.
+  The two don't overlap, so the blob here is row 228's blob plus my three lines, with no landed line
+  reverted. cli tests/host.test.mjs:855 reads this README, and run 1's cli suite covers it.
+
+The other 12 paths are byte-identical to f9fff4300. The line numbers in the step notes below were read
+on the old base.
+
+## Run 1 (sage-1831, sage-1833, sage-1838)
+
+Run 1 on 4d4bb4af6, 07:45-07:54Z, failed: 1351 tests, 1285 pass, 66 fail. The 66 are 33 tests counted
+twice, once in the files run and once in the bus suite. The cli suite, the cli hosts test, seat
+sandbox.test and bus project-runtime.test passed. Two defects, both mine:
+
+- grant-executor.test.mjs, 32 tests. setup() never made `dir/data`, and `new Store` lstats its root
+  (store.mjs:137), so every test stopped at setup with ENOENT. setup() now makes it, mode 0700.
+- credential-claim.test.mjs:76 (X4), 1 test. A register after a revoke left the key in `#revoked`, so
+  status() said `revoked` for a new grant's reference that has no token yet. register now clears
+  `#revoked`, as unregister does. `#revoked` feeds only status(), and issue clears it as well.
+
+Both fixes are amended into the one commit. The rerun covers the five bus files, the bus suite, and
+cli credentials.test.mjs and verbs.test.mjs, which read credential state strings.
+
+## Run 1 rerun (sage-1842, sage-1843)
+
+The rerun on ac7c45975, 08:06-08:07Z, failed: 701 tests, 695 pass, 6 fail, which are 3 grant-executor
+tests counted in both the files run and the bus suite. All three were test defects that run 1's setup
+failure had hidden. No src file changed for them:
+
+- G10. The two fixture decisions were built after `before`, and grantDecision (host-fixtures.mjs)
+  INSERTs one events row each, so the count read 13 for 11. The test now builds them first, asserts
+  they added exactly 2 rows, and then pins the executor's 0 against that count.
+- G27. setup's t.after removes the scratch dir before a hook the test adds later runs, so the test's
+  chmod hook hit ENOENT after the body had passed. The body now restores the mode in a try/finally.
+- G22. The slow run's promise had no handler until `refusesWith`, four lines on. The revoke rejected it
+  first, and node failed the test on the unhandled rejection. The handler now goes on at creation.
+
+The fix is one more amend of the single commit. The rerun is grant-executor.test.mjs whole plus the bus
+suite.
+
+Rerun 1c on 5df4b52c5, 08:15Z, was green: 623 of 623, grant-executor 34 of 34 and the bus suite 589 of 589.
+
+## Mutants B1-B37 (sage-1894, sage-1899, sage-1904)
+
+Three chunks ran on 5df4b52c5, 09:22-09:37Z. Restores matched HEAD after each. 33 were killed and four
+survived. Two of the misses were mine, in the file lists:
+
+- B2 and B23 listed only grant-executor, and that file never makes the raise either mutant changes.
+  grant-enroll.test.mjs:227 (A2, A4) resolves a plain `credential.mint` yes and a host grant no, and
+  asserts no grant events for either. mutants.py now lists grant-enroll and grant-executor for both.
+  B2 then ran alone and A2 killed it. B23 runs again with this round's tests.
+
+The other two survivors needed tests, and Sage ruled on all four (sage-1904):
+
+- B16 drops the abort check after `verify`. The check after `step('commit')` still ends the grant
+  revoked, so G23 X5's asserts held. The run then logs a commit step for a grant that never committed.
+  G23 X5 now asserts that its only `grant.step` is `install`.
+- B17 adds `await null` after the commit check. Sage accepted it as equivalent. `await null` yields
+  only to microtasks. Every revoke starts in a macrotask of its own (a socket request, or a test's
+  call), so none can land in that gap. There is no test for it.
+- B27 makes issue's commit callback async. issue() doesn't await it, so the executor returns `applied`
+  before the INSERT runs. The two differ only when the commit transaction throws, and a real store can
+  throw there with a full disk, an I/O error or a busy timeout. Under the mutant that throw becomes an
+  unhandled rejection after the key file is written, and the catch's undo never runs. The new G8 test
+  makes the store's `run` throw SQLITE_FULL once on the host_grants INSERT. It asserts host-failed, no
+  record, key file, reference or line, and the steps install, commit, failed. The store object comes
+  from the test's setup, so src gains no seam.
+
+These two test changes went in as a new commit on gizmoduck/row235-d (8b13d0ca0). That branch then
+moved onto row 213's landing as gizmoduck/row235-e, below. B16, B23 and B27 run there, after the touched
+test files run whole.
+
+## Rebase onto 62ddc96cc (sage-1922)
+
+Row 213 landed as 361ba2387, and refactor's tip is 62ddc96cc, with only docs past it. gizmoduck/row235-e
+starts at 62ddc96cc and cherry-picks 8b13d0ca0's one commit. The patch-id is unchanged (c062b73fa9f1).
+row235-c and row235-d stay as they were.
+
+Between 4ced5e63d and 62ddc96cc, 361ba2387 is the only commit that touches a file of mine. The one
+drifted path is `packages/bus/src/broker.mjs`:
+
+- 213 adds `CREATIVE_DEFINITIONS` to the vocabulary import at :6, and refuses `decision.raise` from a
+  creative role with `decision-not-allowed` at :2176. Both hunks stay as landed.
+- My 31 removed broker lines read the same before and after the cherry-pick, so no landed line is
+  reverted.
+
+`packages/cli/README.md` isn't in 361ba2387. Every other path of mine is byte-identical to 8b13d0ca0.
+Line numbers in the section below were read on the row235-e working tree; earlier sections keep theirs.
+
+## Creative roles get no host grant (mos-1163, sage-1905, sage-1908, sage-1916)
+
+Brief blob b16e236188f6 (4364dddb0, rev 2784) requires two refusals: the writer, at the raise and at the
+step 1 recheck, and host.run at spend time, with the record kept. Webby's N2 on row 213 r4 asks whether
+a creative role can spend a decision another role raised.
+
+The spend answer. Mos confirmed it read-only (mos-1164, sage-1916) on 8b13d0ca0 and 01e1fe512; the
+row235-e line follows each:
+
+- Only the chief raises a host grant. `#raiseGrant` refuses `grant-chief-only` for any other
+  definition: :1232 on 8b13d0ca0, :870 on 01e1fe512, :1238 here. The hosts verbs check the same at
+  :1307 on 8b13d0ca0, :896 on 01e1fe512, :1313 here. `chief-of-staff` isn't in `CREATIVE_DEFINITIONS`.
+- No agent spends one. `#consumeGrant` (:697) is called for a host grant only from `#runHostGrant`
+  (:902) and from the restart reconcile (:1106), which ends it interrupted. `#runHostGrant` starts from
+  the resolve hook (:2881) only when `#approvedGrant` returns a grant, and that needs a close by the
+  business's human, via cli, with the raise's approval choice (:691). An agent's resolve records via
+  `broker`, so it starts nothing (grant-enroll A3). The public `runHostGrant` (:891) is a trusted API
+  that no verb reaches.
+
+So a creative role can't raise, approve or spend a host grant. The gap was a different one: the chief
+could raise a grant whose `agent` is a creative role, and the human could approve it. The only check on
+that agent was `#hostDefinition`, which refuses `host-not-declared` (:864) unless the definition's
+`credentials` names `host`. Row 213's `checkCreative` (business/src/role.mjs:143) limits a creative
+role's tools, authority and messaging, not its `credentials`, so a creative role file naming `host`
+passed both the raise and the step 1 recheck.
+
+As built:
+
+- Writer. `#hostDefinition` refuses `host-creative-role` (:862) before the `host-not-declared` check.
+  The raise binding (:1266) and the step 1 recheck (:879) both call it, so a grant raised before its
+  agent's instance moved to a creative definition ends at step 1, spent, with no remote step.
+- Spend. `#hostAccess` refuses `host-creative-role` (:714) when the agent's current definition is
+  creative, before it reads the record. Both callers go through it: host.run (:2543) and the host.sudo
+  raise (:2778). The record stays, because revoke still owns the cleanup (sage-1908). This goes past
+  the brief's writer line in the same direction; Sage tells Mos.
+
+Tests:
+
+- grant-host.test.mjs:115. A `muse` role on a `research` definition that declares host. The raise
+  refuses `host-creative-role` and adds no decision.
+- grant-executor.test.mjs:947. The restart moves `ops` to a creative definition that declares host,
+  then a fixture grant runs. It ends `host-creative-role` at step 1, the decision is spent, and there is
+  no remote request and no record. The fixture comes after the restart, because the restart's reconcile
+  ends any resolved, unspent host grant as interrupted.
+- grant-executor.test.mjs:958. An applied grant, then a restart with `ops` creative, then host.run
+  refuses `host-creative-role`. No remote request is added, sudo.log has no `systemctl`, and the record
+  is still there.
+
+The broker clones `businesses` when it's built, so a definition change needs a new Broker. The test's
+`restart()` gains a `business` parameter, default unchanged, for that.
+
+Mutants: B38 removes the `#hostDefinition` line, run against grant-host and grant-executor. B39 removes
+the `#hostAccess` line, run against grant-executor.
+
+## Run 2 (sage-1928)
+
+Run 2 on 534f2254a, 10:12:52-10:14:51Z, was green. grant-host.test.mjs 9 of 9, grant-executor.test.mjs
+37 of 37 and grant-enroll.test.mjs 24 of 24, each run whole. grant-enroll is unchanged, but it drives the
+broker, and broker.mjs changed. Then the five mutants, all killed, with the restore matching HEAD:
+
+| Id | Killed by |
+|---|---|
+| B16 | G23 (X5), the revoke as verify returns |
+| B23 | A2, A4 |
+| B27 | G8, the store fault in the commit transaction |
+| B38 | both mos-1163 tests |
+| B39 | the sage-1908 test |
+
+## Mutant results, B1-B39
+
+| Run | Head | Killed | Survived |
+|---|---|---|---|
+| B1-B13, 09:22Z | 5df4b52c5 | 12 | B2 (file list) |
+| B2 alone, B14-B37, 09:28-09:37Z | 5df4b52c5 | 21 | B16, B17, B23, B27 |
+| B16 B23 B27 B38 B39, 10:13Z | 534f2254a | 5 | none |
+
+38 of 39 are killed. B17 is equivalent (sage-1904), for the macrotask reason in the B1-B37 section.
+B1-B37 ran on 5df4b52c5, before the move onto row 213's landing, and weren't rerun on 534f2254a.
+`--check` matches all 39 anchors once on 534f2254a.
+
+## Carry list
+
+- N10 (duckworth-0084, row 234 r1): `cli/src/hosts.mjs:30-31` reads `shape[verb]` off a plain object,
+  so `mosaic hosts constructor` passes usage and the bus refuses it with exit 2 instead of 4. Row b adds
+  `hosts revoke` and `hosts sweep` to the same table (design r6 :562, :680), so the fix goes in with
+  them: `Object.hasOwn(shape, verb)` and a usage test for an `Object.prototype` name (sage-1726).
+- Untimed tables (sage-1745, row 234 r3): stack-release T46 lists hosts and host_grants as untimed
+  because every write to them shares one store transaction with a `grant.*` events row. Row a writes only
+  hosts. Every host_grants INSERT, UPDATE and DELETE row b adds must do the same, and BUILD.md lists each
+  with its event line. A write without one is a stop to raise with Sage.
+- N12 (duckworth-0086, row 234 r3, doc-only): row 234's round 3 list of other schema hits leaves out
+  `packages/cli/tests/stack-release-fixture.mjs:214` and `scripts/test-land-work.sh:254`. Both look up
+  one table by name and need no change. If row b changes the schema, its grep list names them.
+
+## What row a already gives row b (b0320d395)
+
+- `#approvedGrant`, `#consumeGrant(business, decision, method)` and `GRANT_EVIDENCE` (broker.mjs:667-690).
+  Row b calls `#consumeGrant` with `'host'`.
+- `#openGrantDecisions(business, method)` and `reconcileGrants()` (broker.mjs:823-860), which today handle
+  `host-enroll` only. Row b adds the `host` method, the `grant.step` undo table (r6 X3) and the
+  revoke-marker reconcile (r6 section 6, N4).
+- The resolve hook at broker.mjs:2444-2445 starts `#runEnrollment` for `host-enroll`. Row b adds the same
+  start for `host`, under the same human, via cli and choice checks.
+- `host.run` already reads the store grant record and checks the Approve record (broker.mjs:691-703).
+- The raise check `grant-chief-only` (broker.mjs:870, :896). `host-grant.mjs:55` refuses every method but
+  `host-enroll`, and row b opens it to `host`.
+- `Credentials` has `#inflight` with the `host-busy` claim inside `runHost` (credentials.mjs:118, :355).
+  It has no `claim`, `abortClaim`, `register` or `unregister`. Row b adds those (r6 X4, X5).
+
+## Plan, in build order
+
+1. Raise binding (r6 R1-R4): the `grant` argument for `method: 'host'`, `host-not-declared`,
+   `host-not-ready`, the 210 D6 argv rules, `rotateBy`, the rendered block and the 4096 cap, and the raise
+   body hashes. Tests G1-G5, G19.
+2. `Credentials.claim`, `release`, `abortClaim`, `register`, `unregister`, with the shared reference check.
+3. The executor in `bus/src/host-grants.mjs`, steps 1-6 (r6 X2), with failure undo (X3) and the abort rule
+   (X5, C1). Tests G7-G10, G15, G23, G24.
+4. Restart reconcile for `grant.step`, unspent `host` decisions, and the start sweep of `host.<id>` key
+   files with no record (r6 X3, N1). Tests G11, G27, G28.
+5. `hosts.revoke` and `hosts.sweep` verbs, plus the CLI `revoke` and `sweep` with N10. Tests G12, G13,
+   G26, G27.
+6. G22 end to end on one bus. Then the mutant list from r6 section 10 for row b, numbered B1 onward in
+   this file, with the upsert mutant and the abort-after-commit mutant included.
+
+There is no schema step. If one turns out to be needed, I stop and ask Sage to re-brief first.
+
+## Step 1 notes (raise binding, read on b0320d395)
+
+Where the code goes:
+
+- `#raiseGrant` (broker.mjs:866-885) runs the checks and keyscan for `host-enroll` today, and every raise
+  with `grant` reaches it (:1738-1739). Row b branches on `a.grant?.method`. `host` takes no keyscan, so
+  its checks can all run inside the one raise transaction, as R4 asks.
+- `enrollCheck` (host-grant.mjs:50-69) refuses every method but `host-enroll` (:55). Row b adds a sibling
+  `hostGrantCheck` for the R4 shape `{method, agent, host, commands, rotateBy}` and keeps `enrollCheck`
+  as it is, so the 234 tests don't move.
+- The raise body is at broker.mjs:2270, :2345-2353 and :2391. `enroll` becomes a generic `grant`
+  binding. The question block for `host` follows the `host.sudo` block (:2337-2341): agent, host id,
+  address, user, sudo, each prefix JSON-quoted, rotate date, and new key or changed commands. The
+  4096 cap comes from `string(question)` (:2354).
+- The argv rules come from `checkCommands` (business/src/hosts.mjs:67-87): no wildcard, no empty prefix,
+  no glob characters, a bare name or an absolute path, and `refusedCommand` for shells and runners. It
+  throws `refuse(...)` with a message, so the bus maps any throw to `invalid-request`, as `enrollCheck`
+  maps `checkAddress` (host-grant.mjs:57-61).
+- `host-not-declared`: the agent's definition must list `{"service": "host"}`. business.mjs:126-129 reads
+  `definition.credentials` and filters out `HOST_SERVICE` (vocabulary.mjs:113). The bus needs the
+  definition's service list. Read how the running business exposes the definition before choosing.
+- Both lookups are answered. `loadBusiness` returns `definitions`, each role file's validated document
+  (business/src/business.mjs:114-124, :159, returned at :267). `busBusiness` clones the whole business
+  (bus/src/business.mjs:7), so the broker has `b.definitions`. `#definitions` already reads it
+  (broker.mjs:1027-1029), and the comment there says the broker doesn't read `roles/` (sage-0590).
+  - `host-not-declared` checks `b.definitions[b.roles[agent].definition].credentials` for
+    `{service: 'host'}`. role.mjs:118 normalizes a host entry to exactly that.
+  - Deviation from R4: `definitionSha256` is sha256 over `canonicalJson` of that validated definition,
+    not over the file's bytes. The broker doesn't read `roles/`. A whitespace-only edit to the file no
+    longer voids an approval, but any change to a field the loader keeps still does. The bus sees a
+    definition change only after a business reload or restart, the same as every other role field.
+    This goes in the round 1 note.
+
+Assumption, accepted for round 1 by Sage (sage-1782), for Duckworth to check in review: design R4 says `rotateBy` is "a date inside 210's rotation window", but 210
+defines no window in code. It checks only that the value is a real calendar day (bus
+credentials.mjs:16-20, issue at :245). The business load calls a past `rotateBy` a problem
+(business/src/credentials.mjs:114). So the raise takes a real day strictly after today, UTC, and refuses
+`invalid-request` otherwise. There is no upper bound, because no requirement states one and 210
+checks none.
+
+## Step 1 as built (not run yet; no slot)
+
+- `hostGrantCheck(grant, today)` in host-grant.mjs takes exactly `method`, `agent`, `host`, `commands` and
+  `rotateBy`. `agent` must match ID_PATTERN and `host` HOST_ID. `commands` goes through `checkCommands`,
+  and any throw becomes `invalid-request`. `rotateBy` must pass 210's `day` (now exported from bus
+  credentials.mjs) and be later than the bus clock's UTC day.
+- `#raiseGrant` branches on `a.grant?.method === 'host'` after the chief check and before `enrollCheck`.
+  So a host-enroll shape with `method: 'host'` still refuses `invalid-request`, and the 234 G1 list holds.
+- `#hostGrantBinding` runs inside the raise transaction. It refuses `unknown-role` for an agent that
+  isn't a role instance (the code bindLaunch uses, broker.mjs:522). It refuses `host-not-declared`, and
+  `host-unknown` for a host with no record, as `#hostAccess` does. A record in `pending-install` refuses
+  `host-not-ready`. R4 names only `host-not-ready`. I picked `host-unknown` for a missing record so
+  "not enrolled" and "enrolled but not checked" stay apart.
+- `commandsSha256` is sha256 over `JSON.stringify(commands)`. For arrays of strings this equals
+  canonicalJson, and step 3's executor recomputes it the same way.
+- `#dispatch` takes `binding = {body, block}` in place of `enroll`. The enrollment block moved into
+  `enrollBinding` at module level with its text unchanged, so the 234 G4 test reads the same question.
+- No new import in broker.mjs, so RUNNER_FILES doesn't change. host-grant.mjs now imports
+  business/src/util.mjs for canonicalJson. Nothing in the sandbox loads host-grant.mjs. Before in-review
+  I still run seat sandbox.test.mjs and bus project-runtime.test.mjs whole.
+- The new-key line reads host_grants (a SELECT). Step 1 writes no host_grants row.
+- Tests: bus/tests/grant-host.test.mjs, G1 (host), G2, G3, rotateBy, G19, R4/G5 body hashes, G4 block.
+  The G5 tester-thread case: a thread run is always THREAD_DEFINITION, never chief-of-staff, so
+  `grant-chief-only` refuses it first. The test covers the tester's own cap (`tester-refused`).
+
+## Step 2 as built (not run yet)
+
+- The constructor's per-reference checks moved into `#checkRef`, in the same order, and `register` calls
+  it (r6 X4). `register` reads no file. A key file that a failed revoke unlink left at the path stays
+  unused until the start sweep (step 4) removes it. `register` refuses `credential-reference` while the
+  entry holds a live token. An entry with no token, revoked or never issued, is replaced, so a new grant
+  after a revoke registers again.
+- `unregister` drops an entry with no token and clears its revoked mark. A live token refuses.
+- `claim` refuses `host-busy` when the slot is held, by a claim or a `host.run`, and returns the signal.
+  It needs no reference, because the executor claims at step 1 and registers at step 5.
+  `release(instance, service, signal)` frees the slot only for its own signal. I added the signal
+  argument so a late release can't free a later claim.
+- `abortClaim` aborts whatever holds the slot and returns `{pending}`. An aborted claim keeps the slot
+  until the executor releases it in its `finally` (X2).
+- Tests: bus/tests/credential-claim.test.mjs. The D5 `use(` allowlist is unchanged.
+
+## Step 3 as built (not run yet)
+
+Where the code goes. The remote steps are in host-grant.mjs (`grantKey`, `install`, `verify`, `remove`)
+and the orchestration is `#runHostGrant` in broker.mjs, next to `#runEnrollment`. BUILD.md's plan said a
+new `bus/src/host-grants.mjs`. I kept row 234's split instead: the broker holds every store write and
+host-grant.mjs holds the network and key files. A new broker import would also change what the sandbox
+must mount (RUNNER_FILES), and this way broker.mjs gains none.
+
+The broker gets `hostKeys`, made by `grantKeys({credentials, storeRoot})` in host-grant.mjs. It wraps
+only `claim`, `release`, `abortClaim`, `register`, `unregister`, `issue` and `revoke`, keyed by
+(business, agent, hostId). The broker still never gets `use()`. runtime.mjs builds it and passes it in.
+`hostReference` gives the store reference, and the runtime's start load uses the same function.
+
+Every host_grants write in step 3, with its event (sage-1745):
+
+| Write | Where | Event in the same transaction |
+|---|---|---|
+| INSERT, a new key | the `commit` callback that `issue` calls | `grant.applied` |
+| UPDATE commands and decision, a commands change | step 5's transaction | `grant.applied` |
+
+No other step 3 code writes host_grants.
+
+Deviations from r6, for the round 1 note:
+
+- `grant.applied` commits with the record, inside `commit`, not after `issue` at step 6. The untimed-table
+  rule needs an event in the record's transaction. `grant.step commit` can't be that event, because X2
+  writes it before the key file. So X3's "5 after commit" row has nothing to undo in the executor: once the
+  record commits, `grant.applied` has too. What's left in `issue` after `commit` is the memory fill, which
+  writes no file and no store row. The executor sets `committed` after the transaction returns and from
+  then ignores an abort (C1). The restart reconcile (step 4) keeps the commit row, because a crash can fall
+  between the key file write and `commit`.
+- Event bodies name the decision as `grantDecision`, as row 234's enrollment events do. The consume record
+  is the only grant body with `decision`, so `#spent` counts it and nothing else.
+- For a commands change, `grant.applied` has `fingerprint: null`. The executor holds no key on that path.
+  The record's `rotate_by` stays. X2 names only commands and the decision id.
+- The keygen dir goes as soon as `grantKey` has read the key back into memory, not in step 5's `finally`.
+- Step 4 runs `true` as the remote command as is, not through the sudo argv, since a user with no sudo
+  must pass it too.
+- `hostGrant()` takes `installerUser`, `mosaic-installer` by default. Only the tests change it, because
+  the scratch sshd logs in only as the test's own user.
+- A commands-change UPDATE that changes no row ends `host-changed`. Only a revoke deletes a live record,
+  and a revoke aborts the claim first, so this is a guard.
+
+Step 1 codes, after the spend and in its transaction: `host-not-configured`, `unknown-role`,
+`host-not-declared`, `decision-mismatch` (definition, registry or commands hash), `host-unknown`,
+`host-not-ready`, `revoked` (a `grant.revoked` of the agent and host after the raise). The definition
+check moved into `#hostDefinition`, which the raise binding uses too.
+
+Tests: bus/tests/grant-executor.test.mjs, a scratch sshd on 127.0.0.1 with stub `list`, `add` and
+`remove` that edit a second authorized-keys file. G7 (new key, and a commands change), G8 (install, verify,
+a failed remove, step 5 before commit, a failed step 1 check), G9, G10, G15, G23 (a revoke during install
+through `abortClaim`, a `grant.revoked` before start, and a held slot), G24's tag part. G23's held slot
+uses `claim` in place of a running `host.run`. Both hold the same `#inflight` entry. The `revoke` verb
+comes in step 5, so G23 here writes `grant.revoked` through the fixture writer and aborts through
+`abortClaim`. Step 5 adds the verb's own path.
+
+## Step 4 as built (not run yet)
+
+The restart reconcile has three parts, in start order:
+
+1. `sweepHostKeys` (host-grant.mjs), in runtime.mjs right before `Credentials` loads. In each loaded
+   business's agent store it unlinks every `host.<id>` file that has no `host_grants` record, and logs
+   one `hosts: {"event":"host-key-swept",...}` line per file to stderr. A store dir that isn't private
+   refuses `credential-file`, and so does the start. A name that isn't `host.` plus a valid host id
+   stays, so ssh-keygen's `.pub` stays too. A business the bus didn't load is left alone.
+2. `reconcileGrants`, where row 234 already calls it, after `Credentials` loads and before the socket
+   opens. For a `host` grant it ends a spent decision that has no `grant.applied` and no `grant.failed`.
+   It also spends and ends an unspent one the human resolved yes. Each ends `grant.failed interrupted`,
+   with the tag and a notice. When the last step is `install`, or `commit` with `previous: null`, a line
+   may be left. For those, it claims the (agent, `host.<id>`) slot and queues the decision for part 3.
+3. `reconcileHosts`, which runtime.mjs calls once `serve` returns, with no await, so a start doesn't
+   wait on the network. Each queued decision runs `remove <user> <tag>` through the installer, as the
+   step's `user`. Then it ends `grant.failed interrupted`, with `hostLineLeft` if the remove failed or
+   there's no host record, and releases the claim. The claim makes a new grant for the same agent and
+   host refuse `host-busy` while the remove runs. Otherwise its new line, with the same tag, could be
+   removed.
+
+Deviations from r6's restart table, for the round 1 note:
+
+- No record write on restart. Step 3 commits the record with `grant.applied` in one transaction. So a
+  decision with no `grant.applied` has no record. For a new key, the record undo has nothing to delete.
+  For a commands change, the "back to `previous`" undo has nothing to put back. What's left of the
+  `commit, new key` row is the key file, written before `commit`, and the start sweep unlinks it.
+  The `commit, commands change` row ends interrupted with nothing undone. G28's "a revoke before
+  `grant.applied`" can't happen, because they commit together. Step 5 tests G28 as a change, then a
+  revoke, then a restart.
+- The local undo of row 234's enrollments stays after `Credentials` loads, where row 234 put it. That
+  undo touches only the installer key and the host record, and `Credentials` reads neither.
+- The host grant part writes no `host_grants` row, so the untimed-table rule (sage-1745) adds nothing
+  here.
+
+Fixture change: `hostGrantRecord` (tests/host-fixtures.mjs) writes `grant.applied` after a `grant.host`
+spend, as the executor always does. Without it, a start over a fixture record ends that record's
+decision `interrupted`. Row 234's M3 start test (host-run.test.mjs:602) does that start. No test counts
+the fixture's grant events (checked by grep across the bus tests).
+
+Tests in grant-executor.test.mjs, through a `restart` helper that follows runtime.mjs's order on the
+same store:
+
+- G11 after `install`: the line goes, the slot is held between the two parts, and the grant ends
+  interrupted. A second start adds nothing, and `runHostGrant` refuses `decision-consumed`.
+- G11 after a new key's `commit` with the key file written: no key file, record, reference or line.
+- G11 after a change's `commit`: the record, key and line are unchanged, and the host gets no request.
+- G11 (B2) before step 1, spent and unspent: each ends interrupted with a notice, and the unspent one
+  is spent exactly once.
+- A failed remote undo, and a missing host record: each ends with `hostLineLeft` and the sweep hint.
+- A finished grant: the reconcile adds nothing.
+- N1 (G27's sweep part): only files with no record in loaded businesses go, and a dir that isn't private
+  refuses.
+
+The revoke-marker part of the reconcile (section 6, N4) comes with the revoke verb in step 5.
+
+## Step 5 as built (not run yet)
+
+Two new bus verbs, `hosts.revoke` and `hosts.sweep`, join `HOSTS_VERBS`. The CLI gets
+`mosaic hosts revoke AGENT HOST --reason R` and `mosaic hosts sweep HOST`.
+
+`hosts.revoke {agent, host, reason}` follows r6 section 6:
+
+1. One transaction deletes the `host_grants` record and writes `grant.revoked` with a new `revoke` id
+   (a UUID), the computed tag, `hostLine: "pending"`, `granted`, `reason` and `by`. With no record it
+   still writes the marker, with `granted: false`, so a stale line can be named (N4). A host with no
+   record refuses `host-unknown` and writes nothing.
+2. With no await between, `Credentials.revoke` drops the key from memory, aborts a `host.run` in flight
+   and unlinks the file. With no reference (`credential-unknown`), an executor holds only a claim, so
+   `abortClaim` stops it. Any other throw, such as an unlink that fails, comes back as `keyFile: "left"`.
+   The record is already gone, so the next start's sweep unlinks that file.
+3. `remove <user> <tag>` through the installer, as the host record's user (the executor's user too).
+   Then `grant.revoke.closed` with the same `revoke` id and `hostLine: "removed"`, or `hostLineLeft`.
+
+Callers (G26): the human, and the assistant of the session's business, checked with `#threaded`. The
+tester can call it when `bus.tester` is exactly `true`, read again at the call. Any other agent gets
+`revoke-refused`, a code new in this row. A tester session can't hold a business whose `bus.tester`
+isn't `true`, since `bindTester` refuses `tester-off`, and the broker's businesses don't change while
+it runs. So `tester-dev-only` can't be reached from a test. The check stays for N8, in case a later
+row reloads businesses.
+
+`hosts.sweep {host}` is the human's or the tester's; an agent gets `human-required`. It runs
+`list <user>`, then removes each listed tag that this business recorded for the host in a `grant.step`
+or `grant.revoked` and that no live grant holds. Another business's line and an unrecorded `mosaic-`
+line stay (G24's sweep part). It writes `grant.host.swept {host, removed, left, by}`, where `left` is
+each earlier left tag still listed and not removed. `#hostLinesLeft` now starts from the last
+`grant.host.swept` and adds only later `hostLineLeft` bodies (F4).
+
+The restart reconcile adds the marker part: `reconcileGrants` collects each `grant.revoked` with
+`hostLine: "pending"`, a text `revoke` id and no `grant.revoke.closed` of that id. `reconcileHosts`
+runs step 3 for each. A `grant.revoked` with no `revoke` id, as G23's fixtures write, isn't reopened.
+`hosts.status` adds `revoking`, the tags of the open markers on the host.
+
+Other changes:
+
+- N10: the CLI checks the verb with `Object.hasOwn`, so `constructor`, `toString` or `__proto__` is a
+  usage error.
+- `--reason` is required with `revoke` and refused with any other verb.
+- The reason goes through the broker's `string(x, 500)`, as `credentials.revoke`'s does, so a reason of
+  only spaces is accepted there too.
+- Correction to step 4: the first G11 test expected `list` then `remove`. `reconcileHosts` sends only
+  `remove`, so the test now expects that.
+
+Residuals for the round 1 note:
+
+- A new grant whose line goes in while a revoke's step 3 or a sweep runs can lose that line, if it has
+  the revoked tag. Revoke holds no claim during step 3. If the remove lands after the new grant's
+  verify, the grant is recorded but its line is gone, so its logins fail. I didn't add a claim, because
+  a revoke must not wait on a slot.
+- The enrollment's installer tag is never in the sweep's set, so a `hostLineLeft` naming it stays
+  until the human removes it by hand.
+
+Tests in grant-executor.test.mjs:
+
+- G12: the human's revoke of a live grant, and the bodies of both markers. A restart adds nothing.
+- G12 (N4): a revoke with no record removes the computed tag's line. Bad args refuse
+  `invalid-request` and an unknown host `host-unknown`.
+- G13: a revoke during `install` aborts the executor, which ends `revoked`. A raise before a revoke
+  and started after it ends `revoked` at step 1.
+- G26: who may revoke and who may sweep.
+- G27: a restart after step 1 (the sweep takes the key file, then step 3 runs), after step 2 with the
+  host down (`hostLineLeft`, then a sweep clears it), and a file a revoke couldn't unlink.
+- G28: a commands change, then a revoke, then a restart.
+- G24 (B4): the sweep's tag set, a failing `list`, and the left list it records.
+
+The CLI tests in packages/cli/tests/hosts.test.mjs cover revoke and sweep, the N10 usage cases and the
+`revoking` field in a status line.
+
+## Step 6 as built (not run yet)
+
+New tests in grant-executor.test.mjs:
+
+- G22 (B1), one bus with no restart. The chief enrolls web1, the human approves, and `hosts.check`
+  marks it ready. A grant of `echo` follows, then a `host.run` of `echo hi` that prints `hi`. A
+  `sleep` raise refuses `command-not-granted`, and after a commands change to `echo` and `sleep` the
+  next `host.run` of `sleep 30` starts. A revoke kills that run with `credential-unavailable`. The next
+  call refuses `host-not-granted`.
+- G12: the local steps finish before the host step. With the host's `remove` held, the record and key
+  file are already gone and `hosts.status` shows the tag under `revoking`.
+- G13: a revoke whose host `remove` fails returns `hostLineLeft`, drops the record and key, and closes
+  the marker, so a restart adds nothing.
+- G23 (X5): a revoke right after the executor's spend reaches its claim and the grant ends `revoked`.
+- G23 (X5): a revoke that lands as `verify` returns ends `revoked` with no record, key file or line.
+  Only the abort check after `verify` catches it.
+
+The fixture gains a `sudo` stub (logs to sudo.log, then runs the command as the test's user), a
+`hold-remove` flag, `opts.enroll` (no host record and no installer key) and `opts.wrap` (changes the
+host API the broker gets). `hostGrant` gets a fake `scan` that returns the scratch sshd's host key.
+
+G22 deviations, for the round 1 note:
+
+- `checkAddress` (business/src/hosts.mjs:62) refuses this machine's address, so the test enrolls
+  192.0.2.10 with the fake keyscan. It then points the record at the scratch sshd with an SQL update
+  and adds the enrolled installer key to the sshd's authorized keys. Enrollment, check, grant, run and
+  revoke all go through the real code after that.
+- r6 B1 says the next `host.run` after a revoke refuses `credential-unavailable`. Here it refuses
+  `host-not-granted`, because step 1 deletes the record and `requestHost` checks the record
+  (`#hostAccess`) before it reaches the key. The call in flight does refuse `credential-unavailable`.
+
+### Mutants
+
+`/mnt/storage/scratch/gizmo-235-out/mutants.py` holds each mutant as anchored edits. `--check` applies
+them in memory and runs no test. All 39 anchors match once. Each mutant runs its named test files.

+
+B17 may survive. `await null` yields only to microtasks, and every revoke starts in a macrotask of its
+own (a socket request, or a test's call), so none can land in that gap. If it survives I'll report it
+as equivalent under this build, not add a test that fakes a microtask revoke.
+
+Section 10 items not run as row b mutants, and why:
+
+- The upsert mutant ("let the undo to `previous` insert a record") and "run past a newer
+  `grant.revoked`". Row 235 has no undo to `previous`. A commands change commits the UPDATE and
+  `grant.applied` in one transaction (sage-1745), so a restart after it leaves the record as it is
+  (G11). The UPDATE can't meet a missing record either: step 1 reads the live record, and nothing
+  awaits between there and the UPDATE. An upsert there would be equivalent.
+- "let the executor act on an abort after step 5 commits". The record and `grant.applied` commit
+  together, and no abort check follows the commit, so no code path reaches the `if (committed)` guard
+  with an abort. Removing the guard is equivalent. C1's case is covered by G28 with a later revoke.
+- "treat a missing `bus.tester` as dev". The tester check can't be reached from a test (step 5 notes).
+- Row a's: the keyscan compare, the writer items, the "not yet enrolled" check, the `hosts` primary key
+  and `host.run` reading the business file. Row 234 ran those as A5, A6, A8, A9, A11 and A13-A19.

+
+Gitea #1751, Vikunja P19 445 under #436. Brief: docs/plans/2026-10-20_host-credentials.md, section
+"Machine grant row b follow-up: the undo can't prove the remote add has ended" (6de1ebc62). Reviewer
+Duckworth, gate owner Sage. Branch gizmoduck/row249-on-8a04, on row 248's landing 8a04f4aa4 (sage-2012).
+No file under packages/bus/src changed between 6d5545d44 and 8a04f4aa4, so the brief's src line numbers
+hold on the base. Line numbers below are on this branch.
+
+## Correction to the brief
+
+The brief, copying gizmoduck-0139, puts the sweep's host-unknown refusal at broker.mjs:1350. On
+6d5545d44 it is :1349. On this branch it is :1354.
+
+## The change
+
+`#runHostGrant` in packages/bus/src/broker.mjs:
+
+- :943 adds `installed = false` next to `installing`.
+- :956 sets `installed = true` on the line after `await this.#hostGrant.install(...)`, before the
+  `stop()` that follows it. An abort that lands after install returned still ends revoked, with no hint,
+  because install returning means every request it sent has exited.
+- :1025, in the catch, inside `if (installing)` and after the remove: `if (!installed) extra =
+  { hostLineLeft: tag };`. The remove still runs first and its result doesn't matter. A remove that
+  throws sets the same hint as before (:1021).
+
+The rule keys on install not returning, not on `signal.aborted`. That covers an abort (host-run.mjs:136,
+SIGKILL to the local group), a timeout (host-run.mjs:131-134, SIGTERM, then SIGKILL after `graceMs`) and
+a dropped connection, which fails the request with no signal at all. `#hostGrantFailed` (:845) already
+adds "A line tagged X may be left on the host. Run: mosaic hosts sweep <host>" when `hostLineLeft` is
+set (:852), so the message needed no change.
+
+False hints. install is one call that runs `list`, maybe `remove`, then `add` (host-grant.mjs:329-333).
+Any failure inside it now records the hint, including a `list` that exits 1 before any add was sent, and
+an abort that lands before the first ssh starts (the G23 X5 case at "a revoke right after the spend").
+The brief accepts this for an add that exits nonzero. The other cases are the same kind: the line isn't
+on the host, and a sweep that doesn't list the tag drops the hint (G24, "a left tag no longer on the
+host", broker.mjs:1358). Narrowing it would need install to report which request was in flight, which is
+a change to host-grant.mjs's API that the brief doesn't ask for.
+
+## Row a's enroll
+
+The race can't happen there, because enrollment sends nothing to the host. `#runEnrollment`
+(broker.mjs:772-842) writes the record, calls `this.#hostGrant.enroll(business, host)` (:800) and
+commits the fingerprint. `enroll` (host-grant.mjs:247-286) runs ssh-keygen locally and writes the
+private half to its file. It opens no ssh session. The installer line goes on the host by hand: the
+notice tells ops-01 to write it, then to run `mosaic hosts check`. The undo at :835 is `unenroll`, which
+deletes the local key file. There is no remote add to outlive a kill, and no remote undo to race with.
+
+## Tests
+
+packages/bus/tests/grant-executor.test.mjs:
+
+- `lateAdd` (:451) is the shared tail. After the grant ends it asserts the code, `hostLineLeft` on
+  grant.failed, the sweep line in the notice, and that the undo's remove was the last request. Then it
+  writes `release`, so the held add writes its line and exits 0, and waits for the line in `granted`. It
+  checks there's no record, `hosts.status` lists the tag in `hostLineLeft`, `hosts.remove` refuses
+  host-line-left, `hosts.sweep` returns `removed: [tag]` and the line is gone, then `hosts.remove`
+  succeeds.
+- :468, the abort case. `hold-add`, the human approves, the add holds, `abortClaim` aborts the
+  executor's claim. Ends revoked.
+- :480, the timeout case. A 30 s wait is too long for the file, and making the timeout an option would
+  add a src seam, so the test wraps `install` through `opts.wrap` instead. The wrapper passes install its
+  own AbortController signal, waits for `holding`, aborts it, which SIGKILLs the local ssh group as the
+  timer does, then throws as a timed-out request does. The executor's signal isn't aborted, so it ends
+  host-failed. Nothing under src changes for it.
+- G8 (:283) changes. fail-list and fail-add now carry `hostLineLeft` and the sweep line. noop-add fails at
+  verify, after install returned, so it keeps no hint and the old message.
+- The comment at :436 (:432 at 6d5545d44) now says `skip` makes the held add exit without writing and that a
+  killed session's add can still write. G13 has no such comment.
+
+Both new tests write `release`, so their held stub exits before `t.after` removes the dir. Row 248's dir
+check (:67, :72) is the backstop.
+
+## Mutant
+
+/mnt/storage/scratch/gizmo-235-out/mutants-249.py, on row 235's runner. C1 removes the :1025 line and
+runs grant-executor.test.mjs. Both new tests and G8 should fail under it. `--check` matches its anchor
+once.
+
+## Runs
+
+On Sage's grant sage-2015, at 8457af076 (7cee1a1ab plus this file), TMPDIR /mnt/storage/scratch/g249t:

+After C1 the worktree was clean and broker.mjs matched HEAD. After the runs, no node, sshd or sh process had a
+cwd under the worktree or g249t, and no `fake/add` or `fake/remove` stub was running. The bus suite runs on
+Sage's gate.

+same on both (c33823941e61). Test line numbers moved down by one, and this file was updated for that.

+# Row 250 build notes (Gizmoduck)
+
+Vikunja #450, Mos ruling mos-1182 item 3. Brief: docs/plans/2026-10-21_k12-cohort-events.md. Reviewer
+Filbert, gate owner Sage. Branch gizmoduck/row250 from origin/refactor 3b0aef995. Line numbers below are on
+this branch unless a commit is named.
+
+## Step 1
+
+cbba6ff07 changes only the K12 assertion (packages/conversation/tests/cohort.test.mjs:292 on 3b0aef995).
+On failure it prints the shim's answer, with `ok` and `unavailable`, and `h.ctrl.evidence.releases`.
+
+## Step 2: the cause
+
+K12 reads the shim after the controller has started to release it.
+
+- The force stop sets the binding `stopped` (packages/conversation/src/controller.mjs:1615). Then it pauses at
+  `scope-release` (:1623) and calls `#releaseScope` (:1624).
+- `#releaseScope` calls `releaseCohort` (:1639). That sends `hello`, then `release`
+  (packages/conversation/src/cohort.mjs:261-265).
+- The shim answers `release` and exits 10 ms later. It unlinks its socket first (shim.mjs:165-176). systemd
+  then collects the empty scope, `engine` included.
+- K12's `forceStop` helper returns once it sees `stopped` (cohort.test.mjs:148, polling every 10 ms). The
+  test then reads `engine/cgroup.freeze` (:281 on 3b0aef995) and asks the shim for `events` (:291).
+
+Nothing in K12 orders those reads before the release. Unloaded, the test usually sends its `events` request
+within the 10 ms before the shim exits, so it passes. Under load the release wins. `shimRequest` then
+returns `{ ok: false, unavailable: "the shim socket is gone" }` (cohort.mjs:46), or "unreachable" or
+"closed the connection" (:62-63), and `ev.populated` is undefined. Both recorded failures fit this
+pattern:
+
+- Row 197 proof 4, pair1-b: K12 failed in 339 ms on `undefined !== 0` at :292. 339 ms is far below the
+  3 s `shimRequest` timeout (cohort.mjs:56), so the request didn't time out. The `cgroup.freeze` read at
+  :281 passed, so the scope still existed then.
+- BUILD-LOG.md:4092, row 56's gate: "`populated` undefined with load around 12".
+
+Row 50 (a9cc522a0, #1536) added the release after a proven stop. K12 is older. Its comment still says
+"the shim holds the scope", and that stopped being true in row 50. E1 (cohort.test.mjs:923-925) already
+holds `scope-release` so it can read the shim while the shim still answers. K12 never got the hold. No
+other test reads the shim after a proven stop and expects an answer. R1 expects the shim gone, R3 is an
+uncertain stop, and K15 reads before its stop.
+
+The cgroup read itself has no race. The kill's `waitFor` (shim.mjs:117-126) had already read `populated 0`
+for the stop to be proven. The read is the shim's call to `events()` (shim.mjs:83-96), and it reads one
+kernel file. So the brief's allowance for a bounded retry doesn't apply, and there is none.
+
+The fix goes in the test's setup, which the brief allows ("Use the shim, the cohort controller or the
+test's setup and teardown, whichever the evidence points to"). The controller's release is correct and
+specified (README "Scope release", R1). Delaying it for a reader would change row 50's behavior.
+
+## Step 2: the change
+
+packages/conversation/tests/cohort.test.mjs, K12:
+
+- It runs with `gate()`, holds `scope-release` before the stop, and waits until the hold is reached. Then it
+  does every read that needs the scope: `cgroup.freeze`, `events` and `members`.
+- After the reads it lets the release go and asserts one entry, `["force-stop", "released"]`. This is new
+  coverage: K12 now also shows the forking cohort's scope released.
+- The assertions are unchanged. `populated` must be 0 and the member list must be empty. The step 1 message
+  stays.
+
+packages/conversation/src/shim.mjs:167-168, `release` (:167 on 3b0aef995). It answered a failed `events()` with "the engine
+cgroup is not empty", so it reported unavailable as not empty. The refusal was already safe, but the reason
+was false. Now an `events()` answer that isn't `ok` is returned as it is, with the read's own reason. Only
+`populated` 1 gives "not empty". Nothing else matched that string (grep of packages/).
+

+- K12 as above.
+- R13, the brief's new case, placed after R3. After a proven stop, with `scope-release` held, the test makes
+  `engine/cgroup.events` mode 000. Then:
+  - `events` returns `ok: false`, has no `populated`, and the reason is "engine/cgroup.events unreadable
+    (EACCES)".
+  - On release, the controller records one entry `["force-stop", "unavailable", <that reason>]`.
+  - The unit stays active, and the shim still answers `hello`.
+
+  Then `close()` reuses the stop's release, so there is still one entry. The `finally` closes the
+  controller again (a second close is a no-op), restores mode 444, the kernel's mode for cgroup.events,
+  and releases the scope. On
+  3b0aef995's shim.mjs, R13 fails on the reason, because it reads "the engine cgroup is not empty".
+- K15 already covers a stop, as opposed to a release, with `events` unavailable: the shim gone, the file
+  mode 000, or `engine` missing, each ending `uncertain` with its reason.
+
+## File added beyond the brief
+
+packages/conversation/README.md:599 listed "R1–R3, R5–R12" for cohort.test.mjs. With R13 it now reads
+"R1–R3, R5–R13". The brief's files don't include the README. Sage added it to this row in sage-2082.
+
+## Runs
+
+None yet. They need Sage's slot. Sage's sage-2082 says the run is on the pushed candidate in a clean
+worktree, and that it adds the control-board suite whole, so it counts as the gate run.
+
+## Round 2
+
+Filbert's C1 (#1755 comment 30125): R13 never closed its in-process controller, so the controller's
+socket server (controller.mjs:548) stayed open, and `reap` only kills units and engines. Only `close()`
+closes it (:1789). R13 now calls `h.ctrl.close()` after its checks and asserts one release entry, as R2
+does. Its `finally` also closes the controller, for a failure partway through. The second close is safe:
+`server` is null by then (:1791), and `#releaseScope` returns the cached release (:1634-1648). Branch

+## Rounds
+
+- Round 1: bdf18272a on gosalyn/c2-01, base 32b54ac3b. Webby approved it in Gitea comment 29704.
+- Round 2: d3c7bbf839d9c3bf50f154b18e7e4472fbd005ed on gosalyn/c2-01-r2, rebased onto 9b5362018 after row 232 drifted three paths (sage-1714). Webby approved it at merge scope, rev 2666 against comment 29921 (webby-0052).
+- Round 3: this commit on gosalyn/c2-01-r3, one commit on the row 234 landing c771a36f4 (sage-1736, sage-1779, mos-1160). Row 234 changed scripts/mosaic, so round 3 review covers that one file.
+
+## Round 2 merge
+
+range-diff 32b54ac3b..bdf18272a against 9b5362018..d3c7bbf83 shows one change, the context line where upstream added `credentials` to the scripts/mosaic case line. Patch-id moved from 8f80dfa3 to 175f45c6 for that reason only. All three drifted hunks keep both sides:
+
+- scripts/stack-copy.sh COPY_PATHS reads `packages/queue/src packages/library/src`. Row 232's bundle, --create, --units and instance code is unchanged.
+- scripts/mosaic runs the `library survey` exec block before the case line, and the case line keeps `credentials`.
+- packages/cli/tests/stack-copy.test.mjs adds `packages/library/src/index.mjs` to the copy file list.
+
+## Round 2 singles, evidence for the 19 paths other than scripts/mosaic
+
+Run on d3c7bbf83 in Sage's slot (sage-1723) from 2026-10-21T05:00:09Z to 05:11:29Z. The HEAD and a clean tree were checked first. The counts are an awk sum over the 23 logs: 481 passed, 0 failed, 0 skipped, 0 cancelled, and every file exited rc=0.

+The file list comes from the library tests plus every test that names scripts/mosaic or stack-copy.sh, by basename and by join() path. No 64-hex pin in the tests names a merged path.
+
+## Round 3 scripts/mosaic
+
+The only path both row 234 and this row change is scripts/mosaic. Row 234 added `hosts` to the cli case line and changed nothing else in the file. Round 3 takes the landed blob cce1fdee4 and adds this row's six-line `library survey` block before the case line by hand, so `hosts` stays. The mode stays 100755. The other 19 paths are byte-identical to d3c7bbf83. Against d3c7bbf83 the only difference is the `hosts` context line.
+
+Round 3 runs only the tests that read scripts/mosaic, in Sage's slot. Their counts go to Sage in T3 and onto #1713, since this file can't hold them and stay one commit. Those tests are library survey, cli app, case2-unit, credentials, hosts, host, instances, project, stack-copy, stack-release, stack-release-external, stack-upgrade, tester-reads, tester-threads and usage, queue dispatch, runs task-cli, webui pinned-copy, service and views, plus scripts/test-queue.sh. hosts.test.mjs is new with row 234.

+# Row 221 build notes, C2-20 Bean and Chet persona import (#1722, Vikunja #416)
+
+Brief: docs/plans/2026-10-20_case2-rows.md "C2-20", blob 16847e94ae17 (sage-1834). Claimed rev 2736.
+Rulings: sage-1836 (fence, pairing) and sage-1840 (YAML parser, handoff).
+
+## Base
+
+Built on Morgana's row 213 r4 tip 2b3e67e36 (origin/morgana/row213-r4), since the brief says "After:
+C2-08" and 221 exports 213's fence check. Before review it goes onto 213's landing under a new branch
+name, and its tests run again there.
+
+## What changed
+
+- `scripts/case2-persona-import.mjs`, new. Verbs `stage` and `install`, usage in its header.
+- `packages/cli/tests/case2-persona-import.test.mjs`, new, and `packages/cli/tests/fixtures/case2-persona-import/`,
+  a fixture Hermes home plus `trace.mjs`, the read trace.
+- `packages/harness/src/bundle.mjs`: the three text rules in `readPersona` move into an exported
+  `personaTextFault(text)`, which returns null or the reason, and `readPersona` calls it. Nothing it
+  checks changes and the messages are byte for byte the same, so 213's creative tests hold. There is
+  one copy of the rules and the import calls it (sage-1836).
+- `package.json` and `package-lock.json`: `yaml` 2.9.0 becomes an exact direct dependency (sage-1840 Q3).
+
+## Rulings recorded
+
+Profile to name (sage-1836, answers DESIGN.md:1322 as an implementation ruling, not a PRD change).
+Hermes at df5700ebe has no field holding a profile's own name. `profile.yaml` has only `description`
+and `description_auto` (hermes_cli/profiles.py:798-850), and `agent_name` at cli.py:3494 is skin
+branding with the default "Hermes Agent". So the human passes the pairing as `--pair default=Bean
+--pair chet=Chet`. The script checks both profile directories exist, each name is exactly Bean or Chet
+and the two differ, then prints the pairing with each SOUL.md's byte count and sha256 before it writes.
+The brief's "confirm profile to name" is met by the human supplying and confirming the pairing.
+
+The persona is `<profile dir>/SOUL.md`, where Hermes loads it (agent/prompt_builder.py:1829-1855).
+The default profile's directory is the Hermes root, and others are `profiles/<name>`, with names
+checked against hermes_cli/profiles.py:37. A missing or blank SOUL.md is "no persona", as in Hermes.
+The file is staged byte for byte. Hermes strips it and runs its own scan before use, but this import
+copies her text unchanged.
+
+Handoff between the steps (sage-1840 Q4). `stage` writes 0600 files owned by whoever ran it. `install`
+runs as `<user>` and refuses a staging file that isn't its own or has a group or other bit. The script
+changes no owner. It prints the root step, `chown -R <user>: <staging>`, as an instruction. **Item for
+Jason's go:** who runs stage on `<host>`, and the root chown between the two steps.
+
+## Word list
+
+69 tool names: every literal `name="..."` in a `registry.register(` call under hermes-agent's
+`tools/*.py` at df5700ebe, plus Hermes and Discord. Two more registrations, in tools/mcp_tool.py:4997
+and :5034, and plugin tools (hermes_cli/plugins.py:430) get their names at run time, so a fixed list
+can't hold them. Matching is whole word, any case. `memory`, `terminal`, `todo`, `process`, `patch` and
+`clarify` are ordinary words, so a persona line using them in prose counts, and the count leans high.
+It is a hint for Jason and changes nothing in the import.
+
+## Channel prompts
+
+Hermes takes a platform's block from `<platform>` at the top level of config.yaml, else from
+`platforms.<platform>` or `gateway.platforms.<platform>` (gateway/config.py:1159-1178), and its
+prompts from `channel_prompts` (:1233). The script lists all three by platform, channel id and byte
+count, and says "not text" for a value that isn't a string. The dry run doesn't read config.yaml.
+
+yaml parses with `intAsBigInt`, so an unquoted 18 or 19 digit Discord id prints exactly instead of
+rounding as a double, and with `uniqueKeys: false`, so a repeated key keeps the last value as Python's
+`safe_load` does. `logLevel: "silent"` stops yaml's warnings, which quote config text. yaml reads YAML
+1.2 and Hermes's PyYAML reads 1.1. They differ on scalars such as `yes` and `0123`, but neither
+changes a channel prompt's key or its byte count for a quoted or decimal id.
+
+## yaml dependency (sage-1840 Q3)
+
+Made with `npm install --save-exact [email protected] --package-lock-only --ignore-scripts` at the worktree
+root. `git config core.hooksPath` was unset before and after. npm moved nothing else:

+node_modules/yaml is 2.9.0, from the pinned pi packages (package-lock.json:502 and :556).
+
+Where it runs. `scripts/case2-persona-import.mjs` isn't in stack-copy's COPY_PATHS, and a copy carries
+no node_modules of its own beyond its `npm ci`. So the script runs from a checkout at the reviewed
+commit after `npm ci`, where `import "yaml"` resolves through the root package.json and
+`../packages/harness/src/bundle.mjs` is beside it. Whoever runs `stage` needs read access to that
+checkout and to her Hermes home, which is part of the item for Jason's go above.
+
+## Tests
+
+Round 1, on 213 r4 2b3e67e36, slot grants sage-1851 and sage-1863. One `node --test` per file.
+
+Run 1 started at 08:19:44Z. A 600 s tool timeout on my wrapper killed it at about 08:29:45Z, inside
+stack-release-external, after stack-release took 494 s. One test in this row's file failed in run 1.
+Its filter `includes("per-channel prompt")` also matched the "profile chet: no per-channel prompts"
+line that the next assert checks on its own. That was a test defect, and the script's output was
+right. The filter is now `includes(": per-channel prompt ")`. The kill orphaned one fixture
+holder.cjs, which I killed, and I removed its tmp dirs. Sage counts this as one failure under mos-0823.
+
+The rerun, 08:31:11Z to 08:33:31Z, covered this row's file, stack-release-external, stack-upgrade
+and the fixture dry run. The 15 files that run 1 finished green stand on code the fix didn't touch. Their counts come from run 1.

+## Rebase onto 213's landing (sage-1925)

+refactor tip was 62ddc96cc. I cherry-picked 2d7a99aee onto it under the new branch gosalyn/c2-20-r2 as
+48f044ccc. The patch-id is eb094ae783e9 before and after. None of the 22 paths changed between 2b3e67e36
+and 62ddc96cc. The fence export from sage-1836 Q1 was already in the commit: `personaTextFault` from
+packages/harness/src/bundle.mjs, called by the script. I checked the test list again on the new base by
+grepping tests and scripts/test-*.sh for each non-test path's basename. The new hits name other packages'
+package.json files or write lockfiles in temp dirs, so the 18 files stand. 231 landed after that as
+29ce1e360. It touches only packages/library and the queue-231 packet, none of these 22 paths.
+
+Rerun on 48f044ccc, slot grant sage-1932, 10:18:09Z to 10:30:14Z, after a busy check. All 18 files ran
+whole, one `node --test` each, every rc 0: 419 pass, 0 fail, 0 cancelled, summed by awk. That's two more

+
+Brief: docs/plans/2026-10-20_case2-rows.md "C2-01b survey escapes, list item lines and attachment embeds",
+blob 16847e94ae17. These are Webby's row 212 notes N1 to N3 (webby-0041), split out by sage-1517.
+
+## Base
+
+First built as 777f7358a on 212's first round bdf18272a. 212 landed as ee7b2f137 (sage-1886), so the
+commit was cherry-picked onto refactor fefd54e13 under the new branch gosalyn/c2-01b-r2 as 3647a5a93.
+`git patch-id --stable` is 45911915a9ee before and after. packages/library is the same in bdf18272a
+and in 212's landed round a2c72ac95, so nothing the commit touches moved under it.
+
+## What changed
+
+- N1, `packages/library/src/survey.mjs`: JSON strings escape C0 controls but leave DEL, C1 and bidi
+  controls raw. The new `quote()` escapes those too, and folder names print through it.
+- N2, `packages/library/src/reader.mjs`: front matter parsing records each block list item's line, and
+  a link in a block list carries its item's line instead of its key's.
+- N3, `links.mjs` exports `isAttachment` through `index.mjs`. A wikilink or embed whose target's last
+  segment ends in an extension other than `.md` is an attachment. The reader neither resolves nor
+  indexes it, and it raises no problem. The survey prints a count of body links to attachments.
+- `packages/library/README.md` describes all three, and the links, reader and survey tests cover them.
+
+## Outside readers
+
+`packages/cli/tests/stack-copy.test.mjs:38` checks only that `packages/library/src/index.mjs` exists, and
+`scripts/mosaic:41` execs `survey.mjs`. No test pins a hash of a library file.
+
+## Tests
+
+On 3647a5a93, slot grant sage-1889, 09:20:01Z to 09:20:14Z, after a busy check. One `node --test` per

+## Round 2, after webby-0070 (CHANGES) and sage-1900
+
+Webby's round 1 review is agents/webby/work/queue-231/REVIEW-r1.md at 387f04dfd, rev 2774.
+
+Ruling sage-1900, recorded here as asked. B2: the brief stays as approved (sage-1517, case2-rows.md
+C2-01b N3). Only a `![[x.ext]]` embed can be an attachment. Plain wikilinks and front matter values keep
+resolving, and an unresolved one is R4. README's line "A link to a `.canvas` file or an attachment is
+R4" is back as it was at fefd54e13. B1: resolve first. An embed is an attachment only when it resolves
+to nothing and its target has an extension other than `.md`. So `![[Dr.Quinn]]` with Dr.Quinn.md
+indexed resolves, `![[cover.png]]` gives no problem, `![[missing-note]]` is R4 and `![[note.md]]`
+resolves. My own design ruling after r11 (28213ac27) also made plain links attachments. The brief
+narrowed that, and the brief governs this row.
+
+Changes:
+
+- `links.mjs`: `isAttachment` is true only for a body embed, `link.embed === true && !link.field`,
+  with the extension test as before. Its comment says it goes by name, so the reader asks it only
+  after resolving.
+- `reader.mjs`: every link resolves first. An unresolved one is R4 unless `isAttachment` holds.
+- `survey.mjs`: `quote()` also escapes U+061C (Webby N1). The attachment count now covers body embeds
+  only, since it uses `isAttachment`.
+- Webby N2, my choice of Sage's two options: the survey keeps a count by name and the README says so,
+  "the count of body embeds whose target has an extension other than `.md`", and that `![[Dr.Quinn]]`
+  counts there even when Dr.Quinn.md exists. Checking against the survey's path list would mean a second
+  resolver in the survey, for a count that only guides the mapping.
+- Tests. links: embeds only, with `[[cover.png]]`, `[[Board.canvas]]`, `[[Dr.Quinn]]`, a front matter
+  value and a markdown link all false, and `![[Dr.Quinn]]` true by name. reader: the Shore case now
+  gives R4 for the front matter `"![[portrait.JPG]]"` (line 3), for `[[Board.canvas]]` (line 5) and for
+  `![[missing-note]]` (line 6). The new Dr.Quinn case has Dr.Quinn.md indexed and resolves `[[Dr.Quinn]]` in
+  a block list and in the body, plus `![[Dr.Quinn]]`, with no problem. survey: a U+061C folder name
+  prints escaped, and the attachment count is 1, since `[[map.PDF]]` is a plain link.
+
+Round 2 tests, one `node --test` per file, each run after a busy check.
+
+Run 1, slot grant sage-1903, 09:39:32Z to 09:39:46Z: 60 pass, 1 fail. The new Dr.Quinn reader test failed
+on order alone. All three links resolved to Dr.Quinn.md with the right field, line and embed values, and
+there was no problem. The reader lists body links before front matter links, and my expected array put
+the `relationships` link first. I stopped and reported it (gosalyn-0098).
+
+Run 2, after the test-only fix sage-1907 approved, which moves that entry to the end of the expected array,
+09:43:42Z to 09:43:56Z. Every rc 0.

+fence check and the mkdir race", landed in 335bb3e30. These are Webby's row 221 notes N1, N2 and N4
+(webby-0073, REVIEW-r1 a0a00630e on webby/reviews). N3 is in DEFERRED (sage-1941).
+
+## Base
+
+Branch gosalyn/c2-20b from 335bb3e30, which is row 221's landing 300766450 plus the brief.
+
+## What changed
+
+- N1, `scripts/case2-persona-import.mjs`: the per-channel prompt line prints the platform key, with its
+  fixed `platforms.` or `gateway.platforms.` prefix, and the channel key through `JSON.stringify`. A key
+  holding a newline prints as `\n` inside one quoted line. The profile name on that line is not config
+  text: `pairing` already holds it to `PROFILE_ID`.
+- N2: the dry run calls `personaTextFault` on each persona after its count line. A fault prints as
+  `profile P: persona <reason>, so C2-08's fence would refuse it`, where the reason is the fixed string
+  `personaTextFault` returns, never persona text or a line number. With any fault the run refuses, exit
+  1, and writes nothing, as stage would. The header comment no longer says a fault is counted, not
+  refused, and now says a SOUL.md over four times the fence in bytes refuses before any count, which is
+  what `soul()` already did (Webby's second point under N2).
+- N4: `privateDir` catches an EEXIST from its mkdir and refuses with `<path> was made by something else
+  between the check and mkdir`. Any other mkdir error is thrown as before, since the brief names only
+  EEXIST.
+- Tests, `packages/cli/tests/case2-persona-import.test.mjs`:
+  - The per-channel prompt test expects the quoted keys.
+  - New: a chet config.yaml with a newline in the platform key and in the channel key prints one quoted
+    line, and no output line starts with the forged text.
+  - The dry run heading test now expects the fence fault line, exit 1 and the refusal, still with
+    nothing written. Its persona has two heading lines, which the fence refuses.
+  - New: a persona of 8001 two-byte characters, 16002 bytes and under the 32000 byte cap, makes the dry
+    run print the over 8000 characters fault, write nothing and exit 1. At exactly 8000 it exits 0.
+  - New: the mkdir race refuses by name at stage, for the staging directory, and at install, for
+    `personas/<business>`. Each refused directory is left empty.
+- New fixture `packages/cli/tests/fixtures/case2-persona-import/mkdir-race.mjs`, an `--import` preload
+  like `trace.mjs`. It makes the directory named by `$PERSONA_MKDIR_RACE` just before the script's own
+  `mkdirSync` of that path, so the script meets a real EEXIST from the kernel, not a thrown stub.
+
+## Known limit of N1
+
+`JSON.stringify` escapes C0 controls, `"` and `\`, but leaves DEL, C1, U+2028, U+2029 and the bidi
+controls raw. None of those ends a line on a terminal, so the forged line N1 names can't happen. A bidi
+control could still reorder how the rest of that one line displays. The brief asks for `JSON.stringify`,
+and Sage kept it in sage-1964 because the keys come from Jason's own Hermes config. Note for Webby: row
+231's `quote()` in packages/library covers the wider set, and this row doesn't import it. If you want it,
+ask for it in review.
+
+## Mutants
+
+One per fix, plus a second for N1 so each of its two keys has its own. Each replaces one exact string
+in the script, runs the test file, then restores the script from a copy and checks its sha256.
+
+| Mutant | Fix | Change |
+|---|---|---|
+| M1 | N1 | the channel key prints raw |
+| M2 | N1 | the platform key prints raw |
+| M3 | N2 | the dry run's refusal after a fault is skipped |
+| M4 | N4 | privateDir's EEXIST branch never matches, so EEXIST is thrown raw |
+
+## Outside readers
+
+`git grep` over packages/*/tests/* and scripts/test-*.sh finds `case2-persona-import` only in its own
+test file and in two files of its fixture tree, README.md and trace.mjs, which name the test file in a
+comment. No test pins a hash of the script.
+
+## Tests
+
+Two slot runs, `busy.sh && run.sh` in /mnt/storage/scratch/gosalyn-r247, on the test file alone.
+
+Run 1, grant sage-1969, 11:47:45Z to 11:48:00Z, was red: 14 tests, 12 pass, 2 fail. The fault was in the
+script. Adding `JSON.stringify` to the per-channel line dropped the space after the comma, so it printed
+`"-1001",29 bytes`. The two per-channel tests caught it. run.sh also went on to the mutants with a red
+base, so their counts meant nothing. Sage approved both fixes in sage-1971: the space goes back, and run.sh
+now exits 3 before the mutants unless the base is rc=0 with fail 0.
+
+Run 2, grant sage-1971, 11:49:04Z to 11:49:22Z, was green: 14 tests, 14 pass, 0 fail, rc=0.
+
+| Mutant | Line | rc | Failed | Killed by |
+|---|---|---|---|---|
+| M1 | 237 | 1 | 2 | the per-channel prompt test and the newline key test |
+| M2 | 237 | 1 | 2 | the same two |
+| M3 | 238 | 1 | 2 | the dry run fence test and the dry run heading test |
+| M4 | 192 | 1 | 1 | the mkdir race test |
+
+After the run the script's sha256 was 7031d2c0dc9bd22bc748b364a35b461fc01cb98b795032a2e0ec436f3188d4e4, the
+same as the copy taken before it. The /proc scan found no process in the worktree or the scratch dir.

+# 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:
+
+- SOURCE.json: 91ba149f2fc039a8bed0e6d1ad5da44b80fb8cbec84d0fa4e38616040138596b

+After an explicit author-gate grant, run this command with Sage's actual ID:

+```
+
+No gate or suite has started. Queue order from sage-1454 is 192, 201, 204,
+200, Gander, then 197. No branch deletion is authorized or attempted. Any later
+rebase uses a new branch name, and pr-merge.sh -d stays off under #426(a).
+Whichever of rows 197 and 200 lands second must rerun stack-release singly.
+Clean-candidate wrapper baselines, image preparation and paired proofs remain
+separately gated acceptance work. There is still no source commit or push.
+
+## Implementation approval and final notes, 2026-10-20T20:47Z
+
+Webby-0031 approved r2 in REVIEW-impl-r2.md at 1f404c973. Their static review
+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
+- gate.sh: 48e06e23e45d3484755f8cd79ad5b6dfde5ef4f960081e7c455a2540e707fed1
+- BUILD.patch: 55fe390da17ab926a0593d39e79561abe52756a1b1a2c756ec57f45d90f10fde
+
+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.
+
+
+## Round 6 preparation (sage-1883, mos-1162)
+
+New branch herb/row197-r6 starts at fefd54e13, after the standalone row
+212 landing ee7b2f137. No r5 manifest path changed between e7078e6a8 and
+this base; all 32 r5 blobs and modes were copied intact before the two
+umask changes. No history replay, stash, force push or branch deletion.
+
+executeSteps now launches each argv through /bin/bash with umask 022
+and exec, preserving the process group and argv boundaries. The supervisor
+and gate-lane.sh retain 077, including state, locks, private logs and roots.
+New gate-lane tests assert the actual child umask and created file mode,
+the unchanged parent mask, private log mode, and actual wrapper-created
+state/lock modes. No shell, image preparation, credentials test or other
+existing assertions changed. process.test.mjs equals the landed base;
+lane-image.mjs equals r5. N7 remains DEFERRED at fefd54e13; rows 243 and
+244 own the explicit chmod and PI_AUTH_FILE fixtures respectively.
+
+Read Sage's permitted failed pkg-bus log: process.test startup token refusal
+saw ready.ok true, consistent with inherited 077 narrowing its fixture mode.
+No further diagnostic read of the retained ga-8I3iZc root is needed.
+No r6 tests or probes have run. Source commit, push and new manifest await
+the explicit granted checks. r6-OVERLAP.json records the empty overlap.
+
+
+Sage-1892 focused grant: gate-lane.test whole 13/0, process.test whole
+through executeSteps 8/0, zero skips/cancellations. Syntax checks passed.
+All new umask/mode assertions passed. No Docker, image, lane or proof run.
+Empty /proc cwd/argv scan and removal recorded in r6-granted/cleanup.json;
+clear herb-0068 at 09:21Z. The source matches r5 on 29 of its 32 paths,
+including modes. Only BUILD.md, gate-lane.test.mjs and gate-lane.mjs differ.
+The new r6-OVERLAP.json records the base comparison. No process test edit.
+Sage-1895 authorizes one source commit and seat-only push after range check.
+
+
+## Round 7 preparation (sage-1951, sage-1955)
+
+The r6 proof passed all package suites with the original process.test,
+then failed script-release. The guard injected --no-build into compose run;
+Compose 5.5.1 rejects it before container creation. The old unit test only
+asserted the same invalid argv, so it could not detect this compatibility
+error. This supersedes no-build-flag claims in the historical packet.
+
+herb/row197-r7 starts at b1fece6f0. No r6 manifest path changed between
+fefd54e13 and this base; all 33 r6 blobs/modes were copied intact before
+r7 tests were authored. No history replay, stash, force push or deletion.
+Sage-1955 accepts the private tempRoot/compose-no-build.yaml override,
+mode0600, with build: !reset null and image pinned to the receipt's imageId.
+The guard owns the -f arguments and forces run --pull never --no-deps.
+Caller-supplied Compose config/build/pull options remain refused.
+The existing proof removes successful temp roots and retains failed roots;
+the override stays within that same cleanup ownership.
+
+Tests first: installed-binary run --help before SERVICE checks parser
+acceptance without starting a container. A separate compose config --format
+json check uses the actual candidate compose.yaml, made-up env/auth paths,
+and an empty Docker config directory, asserting no build key and the exact
+pinned image. The no-build-restoration mutant must fail that parser test.
+No test, probe or Docker command has run on r7; waiting for Sage's grant.
+
+Primary references: Docker's merge reference documents !reset null:
+https://docs.docker.com/reference/compose-file/merge/#reset-value
+Docker's run reference documents --pull and --no-deps, with no --no-build:
+https://docs.docker.com/reference/cli/docker/compose/run/
+Installed 5.5.1 acceptance and merged configuration are still unverified.
+
+
+Sage-1956 focused grant, 2026-10-21 11:19-11:21Z: busy check CLEAR.
+Whole gate-lane-image.test on the r6 guard: 9 pass, 2 fail. The installed
+Compose parser emitted unknown flag: --no-build; the other expected failure
+was the missing override helper. No cancellation or skip. After the fix,
+whole file 11/0. The committed r7-no-build.mutant.patch restores the invalid
+flag. Applied only for the installed parser regression: 0/1 with the same
+unknown-flag error, killed. Restored source and whole file passed 11/0 again.
+Both approved node --check commands passed. Empty /proc cwd/argv scan;
+clear herb-0073 at 11:21:04Z. No container start, image build, lane, proof or
+full suite ran. Logs/counts/scan are in r7-granted/ (local run evidence).
+
+The guard supplies both absolute -f paths, suppressing automatic override
+selection, pins receipt imageId, removes build via !reset null and adds
+--pull never --no-deps. Its main entry publishes the override before Docker
+runs. A unique private staging file plus hard-link publication prevents
+partial writes or replacement under concurrent guard calls; existing bytes,
+mode0600, file type and ownership must match, with O_NOFOLLOW on reads.
+The file stays under the run's short private tempRoot for existing proof
+cleanup. Caller Compose options remain allowlisted and config/build/pull
+options refuse. The actual installed Compose config test reports no build
+key and the exact image ID; parser help is before SERVICE, so no container
+operation can run. Fixtures supply made-up env/auth paths and empty Docker
+configuration. Existing image provenance, cleanup and umask behavior remain.
+
+Range check: one source commit on b1fece6f0, same 33 r6 paths plus the
+mutant patch and r7 overlap receipt (35 paths). Thirty r6 paths retain the
+same blob/mode. Only lane-docker.mjs, gate-lane-image.test.mjs and BUILD.md
+differ from r6. process.test and BUILD-LOG equal the landing. No force push,
+branch deletion, history replay or other source edits. Sage-1956 authorizes
+the source commit and seat-only push; fresh proof remains Sage's action.
+
+
+## Round 8 preparation (sage-1979)
+
+The r7 D5 proof passed business and bus, then failed the two installed
+Compose probes in pkg-cli. Their subprocess fixture retained the lane's
+shim-leading PATH but omitted MOSAIC_GATE_DOCKER_RECORD, so the shim read
+an undefined path. This is a test context error; the production guard stays
+byte-identical to r7.
+
+New herb/row197-r8 starts at 5c6f73ed7. None of r7's 35 manifest paths
+changed from b1fece6f0 to this base. Tests choose the record's real absolute
+Docker path when a lane record is set; outside lanes they keep using docker.
+Only the two read-only help/config probes use this helper. The subprocess
+env still holds fixture-only configuration; the record need not propagate
+to it. No run or policy allowlist is widened.
+
+Sage-1979 grants 215's 16 singles first, then r8's normal and lane-shaped
+shim-leading PATH whole-file checks and the record-lookup-removal mutant.
+The shim fixture invokes the actual unchanged guard, with a private made-up
+record naming the real Docker binary. No image build, container start, lane
+or proof is part of r8 checks. No r8 checks have started yet.
+
+
+Sage-1979 r8 checks followed 215's early singles, then clear herb-0078 at
+2026-10-21 12:09:28Z. Whole gate-lane-image.test normal PATH11/0; whole
+actual guard-shim-leading PATH plus private record11/0. The committed
+r8-record-lookup.mutant.patch removes the lookup: installed-Compose argv
+regression0/1, killed with the original Received undefined path error.
+Restored code, repeated whole shim-PATH file11/0. All zero skips/cancellations.
+Logs/counts/fixture metadata/empty /proc cwd+argv scan are in r8-granted/.
+Both 215 and r8 private roots were removed after an empty process scan.
+No image build, container start, suite, lane or proof ran for r8.
+
+Range: one commit on5c6f73ed7. Of r7's35 paths,33 keep the same blob/mode;
+only gate-lane-image.test and this BUILD.md change. The r8 mutant and overlap
+receipt are added. The production guard and all other tooling match r7.
+BUILD-LOG and process.test equal the landing. No history replay, force push,
+branch deletion, live state change or policy widening. Fresh proof remains
+Sage's action after Webby's merge review.

+# Row 215 build record
+
+Owner: Herb. Reviewer: Filbert. Claim: herb-215-start, rev 2753.
+Brief: docs/plans/2026-10-20_case2-rows.md, C2-04, pin
+16847e94ae1768881711318fe81cbb5e6c66b971. Design: Gosalyn r11,
+sections 1.1, 1.3, 2.1, M4, M9 and 7.2.
+
+Base: a2c72ac952df94ecab7e391d5042f49b7f88b816, row 212's reviewed
+candidate, under Q177. Branch: herb/row215. Rebuild on the combined 212+197
+landing when Sage names it. Do not replay or revert landed changes.
+
+## Scope rulings (sage-1848)
+
+1. Add packages/bus/src/runtime.mjs for library adapter injection and the
+   library skip in protectedRoots. The skip has its own consumer test. Change
+   nothing else there.
+2. Add packages/library/src/mirror.mjs, named mirror rather than store. It
+   creates a bare mirror without a remote, reads at the served commit and
+   reads sync state. Export one state filename constant, and export this
+   module through packages/library/src/index.mjs. Row 222 imports the constant.
+3. Add packages/bus/src/server.mjs only to await library.file and
+   library.status, with socket tests proving their replies are results, not {}.
+4. HTTP exposure is deferred. Row 225 owns the library.status route;
+   C2-11b owns library pages. Leave serve.mjs alone. webui/src/cli.mjs gets
+   only callback wiring next to the project-file callbacks on both listeners.
+5. Reuse existing refusal codes where possible.
+6. Build on a2c72ac95 until Sage supplies the 212 landing SHA.
+
+Additional ruling, sage-1852: library-state-invalid is approved for malformed,
+unsafe or mismatched state, including a missing file while the served ref
+exists. The version-1 shared contract below is approved. Row 222 also owns
+runtime.mjs for its sync and timer wiring, recorded in that row's manifest.
+
+Additional rulings, sage-1860, after Filbert's CHANGES on 6a508804f:
+
+- B1 adds packages/cli/src/config.mjs and cli/tests/trackers-boot.test.mjs.
+  trackerFor skips library entries. A real bus boot with tracker.baseUrl and
+  a library entry succeeds and gets no tracker from that entry.
+- B2 refuses a role publish grant naming a library project in the loader.
+- B3 readers use the sync lock. mirror.mjs exports withLibraryLock, with a
+  5000 ms wait bound and library-sync-busy on timeout. Sync locks only the
+  served-ref move and state publication, never the fetch.
+- N3, git-socket doPush/recordPush accepting a library ID, is a later row.
+  Sage records it in DEFERRED.md when 215 lands. No fix here.
+
+## Shared contract with row 222
+
+Agreed in herb-0048, megavolt-0081/0082 and sage-1852. This section is the
+contract Filbert reviews and Megavolt cites for Dewey. It is not a sync writer.
+
+Module: packages/library/src/mirror.mjs. Export
+`SYNC_STATE_FILE = 'mosaic-library-sync.json'`. The full path is
+`join(mirror, SYNC_STATE_FILE)`, inside the bare repository. Only sync.mjs
+writes it, using a sibling temp file, fsync, rename, and directory fsync.
+
+Version 1 has exactly these keys:
+
+```json
+{
+  "version": 1,
+  "branch": "main",
+  "served": null,
+  "lastFetch": null,
+  "lastError": null,
+  "diverged": null,
+  "problems": []
+}
+```
+
+- branch is the configured mapping branch and must match the reader's branch.
+- served is null or a full lowercase 40-hex commit ID. refs/heads/served is
+  authority. The state value must equal that ref, which must name a commit.
+- lastFetch is null or a canonical ISO UTC timestamp.
+- lastError is null or exactly {code, at}. code matches [a-z-]{1,64}; at is
+  canonical ISO UTC. It never holds stderr, prose or a credential value.
+- diverged is null or exactly {commit, at}, with the same commit/time rules.
+- problems uses C2-01's exact {code, path, message, line?}. code is R1-R7,
+  message is that code's fixed RULES text, line is a positive safe integer
+  when present. No file body or arbitrary message is accepted.
+- An absent file and absent served ref return the empty object above with
+  the configured branch. An absent file with an existing served ref refuses.
+- Unknown keys, bad types, unsafe filesystem metadata, invalid JSON and a
+  mismatch refuse library-state-invalid. Reads use a bounded regular owned
+  private file without following links. The read never repairs state.
+- refs/remotes/library/<branch> is not duplicated in this file. Row 222 may
+  read it when it needs the fetched tip.
+
+Exports consumed by row 222:
+
+| Export | Contract |
+| --- | --- |
+| mirrorPath({business, project, dataRoot}) | Require a library entry; return projectRepo's checked path |
+| ensureMirror(context) | Promise of the mirror path; race-safe idempotent bare init; no remote or fetch |
+| servedCommit(mirror) | Promise of full commit ID or null; refs/heads/served only |
+| readSyncState(mirror, {branch}) | Promise of checked version-1 state; compare with served ref |
+| withLibraryLock(mirror, operation) | Await the same exclusive lock as readers, then await operation({readSyncState}); always release |
+
+The lock is a stable private regular file, mosaic-library-sync.lock inside
+the mirror. It is never unlinked. A kernel flock is held by the caller's
+file descriptor. Acquisition waits at most 5000 ms and refuses
+library-sync-busy on timeout. Unsafe lock metadata refuses library-state-invalid.
+
+There is no fs.flock API. The exact protocol is: open the stable file with
+O_NOFOLLOW, check regular/private/owned/single-link metadata, pass its fd as
+child FD 3 to `flock --exclusive --wait 5 --conflict-exit-code 75 3` using
+asynchronous spawn, await
+that child's exit 0, then run the callback while the parent still holds its
+original descriptor. Both descriptors share the open file description, so
+the lock survives acquisition-child exit. Finally close the parent's fd.
+Process death also closes it. No holder child stays alive in the callback,
+no stale file is deleted, and unrelated operation children inherit only 0-2.
+Acquisition never uses spawnSync: the bus must serve other calls while a
+library reader waits (megavolt-0087).
+
+A scratch-only probe on node v26.8.1 at 2026-10-21T08:34:00Z confirmed this:
+acquisition child exited 0; a second flock -n returned 1 while the parent fd
+stayed open; after closeSync it returned 0. The probe removed its own root.
+This was a design probe, not a package test, suite, Docker command or proof.
+
+readSyncState takes that lock around reading the served ref and state file.
+The callback-scoped readSyncState({branch}) supplied by withLibraryLock reads
+under the already-held lock and does not reacquire it. The helper awaits
+asynchronous callbacks and releases in finally. A callback-scoped reader
+used after its callback ends refuses; it cannot escape its lock lifetime.
+
+Row 222 fetches without this lock, then calls withLibraryLock across the
+served-ref move and atomic state write. Its tests hold publication between
+those steps and prove a concurrent reader waits, then sees the new consistent
+pair, including first sync. Row 215 tests that publication shape and timeout.
+A file read releases the lock after snapshotting a consistent served SHA,
+then reads that immutable commit. Row 222's separate outer sync lock spans
+fetch to prevent two sync operations interleaving (megavolt-0086).
+
+Host adapter exports for this row:
+
+- libraryStatus(context): return {project, ...state}, with no repository path
+  or content. Do not fetch or rebuild on this read.
+- readLibraryFile({...context, path}): read a mapped, readable file at the
+  served commit, returning {project, path, commit, content}. No caller-picked
+  commit, working-tree fallback, fetch or write. C2-01's R1/R2/R7 exclusions
+  apply. A never-synced mirror refuses library-commit for a file read.
+
+Row 222 owns syncCommand, sync, writeSyncState, its outer sync lock, the timer
+and state publication. Row 215 owns the shared publication/read lock per
+sage-1860. Sync rebuilds problems with existing readLibrary({repo, commit,
+mapping}). It does not need a second rebuild function from this row.
+
+## Root consumer audit and reviewer notes
+
+On a2c72ac95, ran exactly the sage-1860 audit:
+`git grep -n 'entry\.root\|\.root)' -- 'packages/*/src/*.mjs'`.
+It has 14 hits. runtime.mjs:95, business/cli.mjs:61,72,78,118,
+instance-settings.mjs:142-143, resolve.mjs:44, cli/config.mjs:62-63 and
+project/paths.mjs:42 all get the library guard in this row. business.mjs:233
+and :242 are code-project validation after the library dispatch, not an
+unguarded consumer. queue.mjs:1144 compares queue genesis roots and never
+iterates business.projects; it is safe and unchanged. A second search for
+projectFilePath/business.projects/b.projects found no additional root reader.
+ensureCheckouts destructures root rather than spelling .root; its guard and
+the launcher's filter remain in T1. Bare projectFilePath/loadProject remain
+strict and unchanged.
+
+Filbert N1 is handled at the existing owned paths.mjs boundary: projectRepo
+defaults to record-project use and refuses a library entry with project-invalid.
+Only mirrorPath's internal call opts into allowLibrary. Thus ordinary human
+and tester project init cannot occupy an uninitialized library mirror path.
+No record API or bus argument exposes that internal option.
+
+Filbert N2: ensureMirror failure refuses bus boot. No socket becomes ready.
+The runtime closes resources it opened, following its existing failure path.
+A T4 test uses an unsafe/pre-existing mirror and proves the refusal, rather
+than serving a half-configured library adapter.
+
+## Verification record
+
+Planning stage. No product code, package test, suite, image build, live operation
+or push for row 215 has happened. Product implementation awaits Filbert's
+manifest approval. Sage owns suite and full-gate grants. Row 197's proof
+commit is separate and is not part of this row's changes.
+
+## Implementation ledger
+
+Plan: agents/herb/work/queue-215/MANIFEST.md at 2522025af, approved by
+Filbert in the reply to herb-0056. Execution is inline by Herb under the
+executing-plans and test-driven-development skills. No agent delegation.
+
+Pre-flight: T1's validated mapping feeds T2's protected document and T3's
+mirror context; T3's lock/state helpers feed T4's injected host adapter.
+The shared contract is pinned above, with no interface conflict found.
+
+Sage-1867 overrides COMMON's singles allowance: every test and executable
+probe needs an explicit slot grant. No further probe/test has run since
+that reminder. Read-only inspection and test authoring continue while the
+slot is held. The first red execution is pending; product code is unchanged.
+
+Filbert's approved-manifest build notes: ensureMirror creates the lock in
+its staged directory before publication; a missing lock in an existing
+mirror refuses library-state-invalid. The top-level metadata allowlist
+permits only normal bare Git entries plus the state and stable lock files.
+Tests cover an unknown entry. The host needs /usr/bin/flock; ENOENT yields
+a handled library-state-invalid refusal, never an unhandled child error.
+Lock acquisition uses /usr/bin/flock directly and asynchronous spawn.
+
+T1: consumer and loader regression tests authored, not run. T2: direct M9
+write and serialization regression tests authored, not run. No completion
+or passing claim is made for either task.
+
+Update, sage-1869 focused slot, 2026-10-21T08:47:48Z to 08:51:07Z:
+the busy check was CLEAR before the first test. T1's mapping regression
+failed 0/1 on unsupported kind as expected, then passed 2/0 with the publish
+refusal included. Other focused greens: business CLI 1/0, resolver 1/0,
+instance settings 1/0, seat checkout 1/0, project paths 1/0, sandboxed launcher
+1/0, and trackers-boot whole 2/0. T2's direct writer case failed 0/1 on the
+missing refusal, then its whole new file passed 4/0. Green total 14/0 with
+no skips or cancellations. Logs and counts: granted-t1/. The final /proc
+scan found no test process or fixture cwd/argv reference; its private root
+was removed. Clear sent as herb-0062. Existing files' other cases have not
+been run yet, so T1/T2's full-file acceptance is still pending.
+
+Sage-1874 directs continued authoring and implementation while the landing
+gate/proof holds the slot. T3/T4 tests were written first. Their initial
+red runs cannot execute during that hold; implementation proceeds under
+that owner direction, with no claim of a witnessed red or green for T3/T4.
+Their baseline red and candidate checks need a later explicit grant.
+
+Implementation ruling: initialization uses GNU /usr/bin/mv --no-clobber
+--no-target-directory for its bounded staging rename, rather than Node's
+renameSync, which could replace an empty directory made by a competing
+actor. This preserves pre-existing directories and needs no new package on
+the Linux/coreutils bus host. The host also needs /usr/bin/flock. Neither
+command has been executed for T3/T4 yet. Publication errors fail closed.
+Sync-state reads are capped at 8 MiB, including a checked extra byte; an
+oversized or concurrently changed file refuses library-state-invalid.
+
+T5 static dependency audit found two partial pinned-copy fixtures that copy
+business/src but not its newly imported library mapping validator:
+cli/tests/stack-release.test.mjs:1772 and stack-release-fixture.mjs:309 on
+the base. Each now includes packages/library/src in the existing copy list.
+This changes fixture closure only, no assertion or timeout. The complete
+stack-release file and each test file importing that shared fixture require
+a later granted single-file run. They are outside the four-file T3/T4 slot.
+
+Sage-1879 places the four-file T3/T4 focused run after their 212+197 proof,
+before Gizmoduck, and requires their explicit clear before starting. No run
+has occurred after herb-0062. Row 197's N7 base-image-tag finding is left to
+Sage's DEFERRED entry; no row 197 source change is made here.
+
+
+Focused T3/T4 grant sage-1882, 2026-10-21 09:13-09:18Z: busy check
+CLEAR. Final whole-file results: mirror 16/0, bus library 6/0, WebUI
+library-cli 1/0, project-runtime 3/0, all with zero skips/cancellations.
+Syntax checks passed for the four files and five changed host modules.
+Logs, all intermediate failures, counts and empty /proc cleanup scan are
+in granted-t34/. Baseline a2c72ac95: three focused bus cases 0/3
+(unknown-verb), CLI 0/1 (missing callbacks). Mirror baseline 0/1 is an
+import refusal for the new module, not a witnessed behavioral red.
+An initial whole baseline bus attempt left a runtime after its expected
+failure; its exact runner was stopped, no process remained, and the
+baseline was narrowed to the three bounded broker/socket cases.
+Candidate fixture setup errors and a mock-child timeout were corrected
+before the final whole-file passes. No suite or Docker/image/proof ran.
+
+Filbert's 09:09 publication note: no dependence on mv -n's skipped-rename
+exit status across coreutils versions. Save staging dev/ino before mv;
+only its disappearance plus the same dev/ino at the mirror proves a win.
+A remaining original staging inode means a loss, requiring a valid winner.
+Only that owned original staging inode is removed. Numeric no-clobber
+statuses 0 and 1, including a diagnostic, are tested with a competing
+winner. Spawn errors, signals/timeouts and inconsistent outcomes refuse.
+Coreutils must provide atomic --no-clobber --no-target-directory semantics;
+it need not use any particular skipped-rename status convention.
+
+
+Landing update: prepared herb/row215-on212 on fefd54e13 (includes row 212
+landing ee7b2f137), without history replay or stash. Only BUILD-LOG.md and
+cli/tests/stack-release.test.mjs overlap the a2c72ac95-to-landing change
+set. BUILD-LOG preserves all landed entries and appends the existing Herb
+entry. stack-release preserves the landing plus only the library/src copy
+list addition. No test has run on this landing yet. All further execution
+requires a Sage grant (supersedes the original COMMON singles rule).
+
+
+Sage-1979 early singles on fefd54e13, stopped after file10 per sage-1983:

+Total315/0, zero skips/cancellations. This is an early read only, not gate
+evidence for a merged candidate. The sequential driver was paused during
+file10 so it could not start file11, then terminated after file10 exited0.
+No file11 log exists. Results/logs are in granted-singles/. Later landed
+overlaps require a new branch and all16 singles again after their merge.
+
+
+Current merge preparation per sage-1983/1987: new branch
+herb/row215-on-f827 on f8276c5eb3ecb0aad353ee65e3dd8f7faac5dd87.
+Nine landed overlaps are recorded in current-MERGE.json and the exact
+candidate deltas against the landing are in current-merge-only.patch.
+Two textual conflicts were resolved manually: Broker keeps hostKeys and
+adds library; business.mjs keeps CREATIVE_DEFINITIONS and adds checkMapping.
+The other seven merges preserve the landing plus the original C2-04 edits.
+All other product/test paths match the early215 tree byte for byte. The
+landing's BUILD-LOG is preserved and the existing Herb entry is appended.
+No history replay, stash, force push, branch deletion or source commit.
+No test/probe/syntax check ran on the merged tree after the slot was cleared.
+All16 whole singles need a new Sage grant before candidate commit/review.
+The10 old-base315/0 results are early reads only, never merged gate evidence.

+Source commit: e333af4dc7af3a9d3789c8c0db26a0df8bdddfee, on
+f8276c5eb3ecb0aad353ee65e3dd8f7faac5dd87. SOURCE.json records all30
+changed source/phase-log paths with blob SHA256 and Git mode. The next
+commit contains only this packet. No product change follows the tests.
+
+Sage-2008: start13:15:15.548943Z; end13:27:27.279728Z, 2026-10-21.
+Each of the16 TEST-FILES.txt files ran whole, sequentially. All451 passed,
+with0 failed/skipped/cancelled. Per-file outputs are in granted-2008/;
+EVIDENCE.json records their counts, Node durations and log hashes.

+All29 product/test hashes equal their pre-run values. The final /proc cwd
+and argv scan was empty; the private test root was removed. Clear sent
+as herb-0082 at13:28:38Z. No further runs occurred. No image, Docker,
+lane, proof or full suite was part of this grant.
+
+Before commit, checked f8276c5eb..8a04f4aa4 on every215 source path and
+all16 test paths: no overlap. Row248's grant-executor test is outside them.
+The current root-consumer grep still returns14 sites, all classified by
+the earlier audit: business code roots after dispatch, guarded library
+skips at consumers, and queue's unrelated genesis-root invariant.
+
+Sage-2016 authorizes the source commit, packet receipts and seat-only push,
+then Filbert's candidate review. The landing gate stays with Sage. Earlier
+focused and old-base receipts are archived in granted-t1/, granted-t34/
+and granted-singles/, with their limits kept above. Full package/shell
+landing checks and implementation approval remain pending. No HTTP route,
+remote fetch, sync writer, timer or live operation was added.
+
+Raw Node error logs retain their original space-only lines. Packet whitespace
+checks exclude *.log so the recorded output bytes stay unchanged; source and
+other packet files pass the ordinary diff check.
+
+## Merge-scoped round 2 after rows 249 and 197 (sage-2054)
+
+Row197 landed as a36523713 after proof6 passed 8/8 gates. Row249's
+broker fix is also in this base. Source a6101e21c596e2972ab5a7e3087736075899505e, single parent a3652371338e60187d4e95cee4a0f30f3c8a8f06,
+is on the new herb/row215-on197 branch. The old branch stays untouched.
+No force push, branch deletion or stash was used. The merge was clean.
+
+Only broker.mjs and stack-release.test.mjs changed upstream among the30
+source/phase-log paths. Both retain every landed hunk. The broker keeps
+row249's installed flag and hostLineLeft handling. The stack-release test
+keeps row197's leasePort import, after hook and closed-port lease helper;
+215 adds only its library fixture copy. The other28 blobs and all modes
+match the prior source. All30 paths have exactly the same -U0 added and
+removed lines as f8276c5eb..e333af4dc. BUILD-LOG.md is append-only.
+
+Stable patch-id, old and new: d191e7e9586cd3b7c18310daacdf0c1fdbc8be01.
+r2-range-diff.txt reports only the commit message changed (!); its patch
+is unchanged.
+r2-MERGE.json records every path; r2-merge-only.patch contains both merged
+source diffs against the new base. SOURCE.json names the new source.
+
+Filbert approved round1 in comment30071, rev2897. This round requests
+merge-only review. The earlier451/0 receipts belong to the prior base;
+no test, probe, syntax check, Docker command or lane ran in this round.
+Merged-tree evidence remains pending Sage's explicit clear.
+r2-TEST-FILES.txt proposes all16 original whole singles plus all66
+bus test files whose local import closure reaches broker.mjs, deduplicated
+to80 whole files. This includes shared fixture and runtime imports.
+Sage's slot and row196 landing gate come first. The full landing gate
+remains Sage's. No library behavior, assertion or timeout changed.

+# C2-04 library business entry implementation plan
+
+> Execution: Herb implements in this session using the executing-plans skill.
+> Filbert approves this manifest before any product implementation.
+
+**Goal:** Load a library mapping without giving an agent a checkout, protect
+all project mappings from organization writes, and expose human-only bus
+reads of the bare mirror's served commit and sync status.
+
+**Architecture:** C2-01 checks mappings and reads commits. Business consumers
+skip library entries. A host-only mirror module owns local mirror reads and
+initialization. runtime.mjs injects that module into the broker, preserving
+the broker's sandbox import closure. Sync and HTTP routes belong to later rows.
+
+**Tech stack:** Existing Node ESM, node:test and bounded local Git helpers.
+No dependencies. node_modules remains the plain canonical symlink.
+
+**Spec:** Pinned C2-04 brief; Gosalyn's approved design 1.1, 1.3, 2.1,
+M4/M9 and 7.2; BUILD.md's sage-1848/1852/1860 scope and shared-state contract.
+
+## Constraints and review focus
+
+- Base a2c72ac95; rebase only onto Sage's named 212 landing on a new branch.
+- Existing code-project entries retain root/repo/remote behavior. Library
+  entries have no root or repo override and use C2-01 checkMapping.
+- Preserve the broker's pinned imports. No library import in broker.mjs and
+  no new runner mount. Do not edit serve.mjs or add an HTTP route.
+- No fetch, remote config, credential read, timer, sync writer, bus write or
+  live operation. All tests use made-up content and local repositories.
+- All test/probe runs require Sage's grant (sage-1867), including singles.
+  Stop and report two failures in one gate. Do not push without authorization.
+
+Review focus, with owning tasks below: library-first iteration must not
+break a later code project (T1); serialized documents cannot bypass M9
+(T2); racing initialization must not replace another mirror (T3); stale or
+unsafe state must not leak content (T3); async socket replies must preserve
+the result and human-only admission (T4).
+
+## Paths and evidence from the base
+
+| Product path | Allowed change |
+| --- | --- |
+| packages/business/src/business.mjs | Dispatch kind:library to checkMapping before code-root validation (:228-244) |
+| packages/business/src/organization.mjs | Compare canonical projects in write before publication (:177 onward) |
+| packages/business/src/cli.mjs | Skip library roots in validate, resolve --project and credential exclusion roots (:60-61, :71-79, :118) |
+| packages/business/src/resolve.mjs | Skip library entries while matching a project file (:44) |
+| packages/business/src/instance-settings.mjs | Skip library before projectFilePath (:142), nothing else |
+| packages/seat/src/checkout.mjs | Skip library entries in ensureCheckouts (:315-327) |
+| packages/cli/src/launcher.mjs | Pass only code entries to ensureCheckouts (:354) |
+| packages/cli/src/config.mjs | Skip library entries in trackerFor's root loop (:61-63), per sage-1860 |
+| packages/project/src/paths.mjs | Skip library entries in overlap loop (:41-44); default record use refuses library, mirrorPath internally opts into allowLibrary |
+| packages/library/src/mirror.mjs | New bare init, checked state and served-commit file read module |
+| packages/library/src/index.mjs | Export mirror module interface and SYNC_STATE_FILE |
+| packages/bus/src/broker.mjs | New injected library adapter, human-only admission and two async verbs |
+| packages/bus/src/runtime.mjs | Library adapter wiring, mirror initialization and protectedRoots skip only |
+| packages/bus/src/server.mjs | Await the two library verbs only |
+| packages/webui/src/cli.mjs | Two library read callbacks beside project callbacks on main and tester listener; no routes |
+
+packages/business/src/project.mjs need not change: callers skip a library
+before projectFilePath or loadProject. Do not weaken their code-root checks.
+scripts/stack-copy.sh already copies packages/library/src and needs no edit.
+

+
+## T1. Mapping and consumer skips
+
+- [ ] Add failing business tests: accept a frozen library mapping without a
+  root, retain mixed/only-library documents, and propagate C2-01's mapping
+  and playground refusal codes. A role publish naming a library project
+  refuses at load, even with an otherwise valid fork identity and remote.
+  Existing code validation remains unchanged.
+- [ ] Add a separate regression for each consumer: CLI validate and its
+  credential exclusion roots; CLI resolve --project books has no project
+  layer; resolveInstance finds a later real project; instance settings still
+  writes an unrelated setting; ensureCheckouts returns no library checkout;
+  launcher creates no books workspace clone; projectRepo skips a library
+  while still rejecting overlap with a real code root. Put books first.
+- [ ] Add the real bus boot regression in cli/tests/trackers-boot.test.mjs:
+  tracker.baseUrl is set and books is a library entry; boot succeeds, books
+  produces no tracker, and a later real tracker project still works.
+- [ ] projectRepo(context, {allowLibrary = false} = {}) refuses a library
+  entry by default with project-invalid. Only mirrorPath opts in. Test that
+  ordinary human and tester record initialization leave no directory at the
+  future mirror path; no public verb can supply allowLibrary.
+- [ ] Add runtime's protectedRoots consumer regression in T4's real runtime
+  fixture. A valid credential outside code/data roots still loads with a
+  library entry, and existing credential protections still refuse unsafe files.
+- [ ] Run each changed test singly, confirm the new cases fail for the
+  intended root assumption, then implement only the table's guards and
+  checkMapping dispatch. Re-run the same files singly.
+
+CLI validate reports a library entry as library, without an absent-project
+warning. CLI resolve --project books resolves without loading a project file,
+as the design's skip requires. It does not fabricate project vars or a root.
+
+## T2. M9 at the organization writer
+
+- [ ] In the new business test file, call organizationWriter.write directly
+  with a changed playground prefix and, separately, a changed hybrid entry.
+  Both refuse organization-projects-protected. Snapshot business bytes and
+  changes.jsonl before each call; assert both remain identical afterward.
+- [ ] Cover addition, deletion and changes to code projects too, since M9
+  protects all projects. Reordered object keys are allowed; array changes
+  are changes. An ordinary non-project write still succeeds and logs.
+- [ ] Add a serialization regression so a proposed object's serialized
+  projects cannot differ from those checked before publication.
+- [ ] Run the file singly to see the missing refusal, compare canonical
+  projects against old disk JSON and the document that actually lands,
+  before any publication/receipt, then re-run it singly.
+
+## T3. Bare mirror, served file and read-only state
+
+- [ ] Add failing tests for mirrorPath and ensureMirror: exact projectRepo
+  default, no checkout/remote, retained no-links/overlap protections,
+  idempotence, simultaneous creators and preservation of a pre-existing
+  non-mirror directory or unsafe Git metadata.
+- [ ] Add failing state tests for BUILD.md's full version-1 contract: missing
+  state/ref, valid state, malformed JSON, unknown keys/types, branch mismatch,
+  invalid times/IDs/problem shape, symlink/hardlink/non-private file and
+  missing or mismatched served ref. Assert reads change no bytes.
+- [ ] Add shared-lock tests: withLibraryLock(mirror, operation) waits at most
+  5000 ms, refuses library-sync-busy on timeout and releases after a throw.
+  A reader arriving between the publisher's served move and state write
+  waits, then reads the consistent pair. Cover first sync and fast-forward
+  in independent processes, same-process independent acquisitions and
+  release after owner death. A callback-scoped reader expires on release.
+- [ ] Implement the lock by async spawn of flock on the parent's inherited
+  fd 3, as pinned in BUILD.md. Await acquisition-child exit before calling
+  operation. Never spawnSync during acquisition, which could freeze the bus
+  for 5 s. A parallel ordinary bus read remains responsive while a library
+  read waits. Only the publication/read lock is shared; fetch is outside it.
+- [ ] Add served-read tests against local fixtures containing spaces,
+  capitals, a .canvas and unmapped top-level note. Seed a served ref and state
+  without fetching. A newer unrelated HEAD does not change the returned
+  file. R1/R2/R7 exclusions, traversal, a missing path, a caller commit and a
+  never-synced mirror refuse. Status contains no fixture body marker.
+- [ ] Implement mirror.mjs and index exports using the shared contract.
+  Initialization stages into an owned private sibling directory and renames
+  atomically; a losing creator validates the winner and removes only its own
+  staging directory. Git uses existing bounded safe helpers, no remote.
+- [ ] Run mirror.test.mjs singly, red then green. Re-run C2-01 reader.test.mjs
+  singly if a reader assumption changes. Do not change C2-01 reader rules.
+
+mirror.mjs validates a bare mirror's metadata before Git reads it, including
+no remote/include/indirection. It does not apply inspectGit's working-tree
+.git assumption to a bare repository. Failures reuse library-git or the
+approved library-state-invalid code. State reads are bounded and private.
+
+## T4. Human-only bus reads and deferred Console callbacks
+
+- [ ] Add broker tests for library.file and library.status using injected
+  adapters. Each agent session refuses human-required before adapter access,
+  including bad arguments and an absent adapter. A reader or tester does not
+  gain a human capability. Human calls validate keys, then use checked
+  library context. Secret checking and bounded refusal evidence remain.
+- [ ] Add real startBroker/socket tests for both verbs. Seed only local
+  fixture mirror data. Assert result shape/content and an actual status
+  field, not merely successful transport or {}. Cover never-synced status
+  and runtime's protectedRoots skip. Keep the pinned import-closure test.
+- [ ] Inject a separate library adapter via runtime, initialize only library
+  mirrors, add the two async request paths, and include them in server's
+  awaited list. Do not import library or fs into broker.
+- [ ] Unsafe or pre-existing non-mirror initialization refuses bus boot,
+  closes opened resources and never publishes a ready socket. Add that
+  runtime regression in library.test.mjs.
+- [ ] Wire main and tester Console callbacks beside project-file callbacks.
+  No HTTP route is shipped. The new CLI test captures the startServer
+  options with a test-only module loader and calls the supplied callbacks
+  against a fixture bus, checking the verb and transport identity. No
+  product test seam, UI page, endpoint or serve.mjs change is needed.
+- [ ] Run library.test.mjs, project-runtime.test.mjs and library-cli.test.mjs
+  individually, red then green. Human admission may use the existing
+  fixture authentication seam; do not forge or bypass a live identity.
+
+## T5. Review packet and Sage's gate
+
+- [ ] Search packages/*/tests and scripts/test-*.sh for each changed source
+  path, imports and 64-hex pins. Record the resulting test-file list and run
+  each changed/touched test singly. Stop and report a scope error.
+- [ ] Self-review the diff against this manifest and all acceptance cases.
+  Record results, commands, skips, source hashes and remaining limits in
+  BUILD.md. Request Sage's slot for the required business, seat, cli, project,
+  bus and webui suites and every scripts/test-*.sh. Do not run them ungranted.
+- [ ] After applicable tests are green, make the source commit, build the
+  candidate manifest from the authorized pushed tip, and move the row with
+  scripts/mosaic. Sage posts token-requiring requests; Filbert reviews the
+  candidate. Push only when authorized. No merge or live change by Herb.
+
+## Self-review
+
+Every brief acceptance item is in T1-T4. Added host support paths match
+sage-1848/1860. BUILD.md records the complete 14-hit root audit. State shape
+and authority match sage-1852; the shared read/publication lock follows
+sage-1860 and Megavolt's agreement. Fetch, timers, outer sync serialization
+and HTTP stay with their later rows.
+This is a plan only; no product edits or test execution precede approval.
+
+
+Landing update: prepared herb/row215-on212 on fefd54e13 (includes row 212
+landing ee7b2f137), without history replay or stash. Only BUILD-LOG.md and
+cli/tests/stack-release.test.mjs overlap the a2c72ac95-to-landing change
+set. BUILD-LOG preserves all landed entries and appends the existing Herb
+entry. stack-release preserves the landing plus only the library/src copy
+list addition. No test has run on this landing yet. All further execution
+requires a Sage grant (supersedes the original COMMON singles rule).
+
+
+Current merge preparation per sage-1983/1987: new branch
+herb/row215-on-f827 on f8276c5eb3ecb0aad353ee65e3dd8f7faac5dd87.
+Nine landed overlaps are recorded in current-MERGE.json and the exact
+candidate deltas against the landing are in current-merge-only.patch.
+Two textual conflicts were resolved manually: Broker keeps hostKeys and
+adds library; business.mjs keeps CREATIVE_DEFINITIONS and adds checkMapping.
+The other seven merges preserve the landing plus the original C2-04 edits.
+All other product/test paths match the early215 tree byte for byte. The
+landing's BUILD-LOG is preserved and the existing Herb entry is appended.
+No history replay, stash, force push, branch deletion or source commit.
+No test/probe/syntax check ran on the merged tree after the slot was cleared.
+All16 whole singles need a new Sage grant before candidate commit/review.
+The10 old-base315/0 results are early reads only, never merged gate evidence.
+
+
+Candidate status: source commit e333af4dc7af3a9d3789c8c0db26a0df8bdddfee. The16 whole
+singles passed451/0 under sage-2008 with zero skips/cancellations; raw
+outputs and merge receipts are in this packet, indexed by EVIDENCE.json
+and SOURCE.json. Sage keeps the landing gate. Filbert's implementation
+review and that gate remain pending. Prior315/0 on fefd54e13 is early
+read evidence only. Sage-2016 authorizes the seat-only source/packet push.
