-# 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 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`:

-| 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`.

-
-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

---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" |
-| F11 | no Discord binding | `/srv/mosaic/.mosaic-dev/discord/` is absent or holds no `*.json` (section 2) |
-
-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.

-| 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.
-
-## r6 section 7, test by test
-
-All in `stack-release-external.test.mjs` unless named.
-
-| r6 :742-812 item | Test |
-|---|---|
-| `units-running` (N4), store, log and TAKEN left | `units-running (N4) refuses while a unit is active...`; also checks that `failed` counts as down and that the Console is checked first |
-| activate leaves the pointer, writes `AWAITING-UNITS` and a backup | `activate stages: ...`, which also checks the set's file list, `UNITS.sha256`, no `--user`, no journal call and `status` |
-| `open-activation` with zero, two, the wrong copy, one not open | `confirm and revert refuse open-activation ...` |
-| `confirm` polls: 3 s fails at `--timeout 1`, passes at `--timeout 10` | `confirm polls: bus status good after 3 s fails ...` and `confirm polls to a pass ...` |
-| `stale-start` floor with `started` at .900 | `stale-start: @1792540799 fails ...` and `stale-start is a gate code ...` |
-| `confirm` pass writes pointer, ok, removes marker; timeout writes `FAILED` and exits 1 | the two polling tests |
-| `activation-failed` when `FAILED` exists | `confirm polls: ... FAILED then refuses activation-failed` |
-| lines carry the started op, from, to, activation and backup | `sameAsStarted` in every confirm test, and sequence 7 |
-| `gate` (N2) with and without `--since` | `gate (N2, A2f): ...` and the usage test |
-| `--plan --expect-from` (N5), activate and `rollback --to` | sequence 7 |
-| A3 order: capture-failed, marker-failed, wrapper failure after migrate | `A3 order: ...` and sequence 2 |
-| refusals log no activation; `interrupted` unchanged | `open-activation` test and sequence 5 |
-| PM check: one, none, two, early, not live, other business, other instance; no journal call | `the external PM check reads launches list ...` (modes '', coder, none, twolive, early, dead, other) and `journalCalls` in every external test |
-| `external-pm` | `pm-on and activate --pm-after-harness refuse external-pm` |
-| `revert` restores TAKEN only after a migration | `revert puts the wrapper back and leaves the store ...` and sequences 2 and 8 |
-| `confirm --rollback` per cause, `unrecorded`, `rollback-failed`, mismatch | sequences 1, 2, 3, 5 and 8, and `confirm --rollback refuses rollback-mismatch, and logs rollback-failed ...` |
-| sequences 1-8 | `sequence 1:` to `sequence 8:`, each ending with the `closed` check (one started and one result line, empty `interrupted`, no marker or `FAILED`, a following `--plan` that doesn't refuse `interrupted-run`) |
-| `rollback --to` refuses not-previous; `rollback --restore` finds an external backup | sequence 7, and `confirm --rollback after a --restore swap ...` |
-| `gate` writes nothing | the `gate (N2, A2f)` test and sequence 4 compare the log, the pointer and the state tree |
-| `confirm`, `revert`, `gate`, `--to` refuse without `--units external` | `confirm, revert, gate, --to and --expect-from need --units external ...` |
-| default path: every call carries `--user`; default `--plan` bytes | the two user-mode tests above |
-
-The brief's additions, in `stack-copy.test.mjs`:
-
-- `row 232: copy --bundle copies a SHA the bundle's refactor reaches, byte-identical to copy SHA, and
-  refuses the rest`: a short SHA, a missing file, a symlink, a bundle that fails `git bundle verify`, a
-  bundle with no `refs/heads/refactor`, a SHA not in the bundle, and a SHA the bundle carries on another
-  branch that refactor doesn't reach. The bundle copy's tree matches `copy SHA`'s byte for byte, and the
-  `release:` and `bundle sha256:` lines are checked.
-- `row 232: wrapper --create writes the first wrapper only, the same bytes wrapper ID writes, and refuses
-  over any file`, a symlink included. Without `--create` a missing wrapper still refuses.
-- `row 232: check --units external reads the system units, the default reads the user units`.

-## Mutants
-
-`mutants.sh` in my scratch (not committed, it edits the worktree), 17 mutants: r6's re-pin list (:817-838)
-minus the three `case1-repin.sh` ones, plus the brief's two. Each one applies exact replacements after a
-checked backup, runs `bash -n`, runs its named killers, restores the file and checks its sha256. Two
-controls run first with no change: the whole external file, and stack-copy's `row 232:` tests.
-
-| Mutant | Killers |
-|---|---|
-| m01 `confirm` writes the pointer on a gate failure | `confirm polls: bus status` |
-| m02 `gate_once` in place of `gate` | `confirm polls to a pass`, `stale-start is a gate code` |
-| m03 PM check counts any instance | `external PM check` |
-| m04 PM check drops the `startedAt` bound | `external PM check` |
-| m05 `confirm` takes the newest `AWAITING-UNITS` | `open-activation` |
-| m06 `rollback --to` skips the comparison | `sequence 7:` |
-| m07 the default path drops `--user` from one call (`is-active`) | `user mode: every systemctl` |
-| m08 the timeout writes r4's interim `rollback pending` line | `confirm polls: bus status`, `sequence 1:`, `sequence 5:` |
-| m09 `AWAITING-UNITS` last, after the wrapper | `sequence 2:` |
-| m10 a refusal names the open activation | `sequence 5:`, `open-activation` |
-| m11 `stale-start` is a refusal | `stale-start is a gate code` |
-| m12 `revert` restores without `MIGRATING` | `revert puts the wrapper back` |
-| m13 `confirm` logs op `confirm` | `sequence 7:`, `confirm polls to a pass` |
-| m14 `MIGRATING` after the migration | `sequence 8:` |
-| m15 `gate` takes its floor from the log without `--since` | `gate (N2` |
-| m16 `copy --bundle` skips the reachability check | stack-copy `row 232:` |
-| m17 `wrapper --create` overwrites | stack-copy `row 232:` |
-
-## Deviations and choices
-
-D1. The shared helpers moved to a new file, `packages/cli/tests/stack-release-fixture.mjs`. The brief's
-files list names `stack-release.test.mjs` "where a shared helper moves" but not a destination. Importing
-from the other test file would run its 74 tests twice, so the helpers need a module of their own.
-
-D2. The fixture's T17 check (what a run may never remove) now exempts a rollback set's `AWAITING-UNITS` and
-`FAILED`. `confirm` removes both when it closes the activation (r6 A5 and R4). User mode writes neither, so
-user-mode runs check exactly what they did.
-
-D3. The user-mode argv and `--plan` tests read the base's scripts with `git show cb5fdb064:` rather than
-storing their output as a fixture file. A later row that changes user-mode output on purpose moves the
-`BASE` constant in the test to its own base, or the test fails. I chose this over a stored fixture because
-a stored copy can drift from the base without anyone noticing.
-
-D4. `marker-failed` is reached by making `state/stack-rollback` unwritable. r6 says "an existing `$RS`", but
-`next_activation` never picks a taken name, so no test can make the run meet an existing `$RS`. The
-exclusive `mkdir` is still what refuses.
-
-D5. The stale-start polling case turns the enter time to `@1792540800`, not r6's `@1792540805`, with the
-started line at 1792540800.900. That also checks that the floor is the whole second, so .900 doesn't push it
-to 1792540801.
-
-D6. No fake `sudo` or `case2-unit.sh`. r6's sequences ran under them because r6 had `case1-repin.sh` drive
-the steps, and that script is I3's. Here the test plays root: it stops and starts the fake system units and
-installs with the existing `bus-service.sh` and `webui-service.sh` stand-ins, between the real
-`stack-release.sh` calls, on one log.
-
-D7. The fake marker in the `open-activation` test is named `20000101T000000Z-<C1 prefix>` so it sorts
-before the real one. A marker that sorted after it would leave m05 (newest marker) alive.
-
-D8. m10 sets `ACT` inside `open_activation`, where r6's wording ("ACT set before the checks") lands in this
-code. `ACT` is set only after every check in `confirm`.
-
-D9. Row 200's `--sso` is a usage error under `--units external`, with the proof flags, `--no-proof` and
-`--no-send`. It is a Console flag, and root's Console unit carries the Console flags; the script under
-external renders no Console line and never calls `console_for_target`, so `sso_checks` doesn't run there
-either. The usage text, the TOOLS.md bullet and the external usage test name it.
-
-D10. Row 200's `config_checks` runs under `--units external` too, after `plugin_checks`, in both the
-`--plan` and run paths of `activate` and `rollback --to`. It checks the target's loader against the stack
-user's `config.json`, which the bus on a VM still reads, so a `console` key the target refuses would break
-root's bus start the same way. The cost is one more refusal (`config-console-key`) an external run can
-print; I took it over a bus that fails after root's start. The rebase changed no user-mode line: the
-conflicts were the `SSO=0` globals line, the `plan` body (row 200's `SSO_PLAN` line sits in the user
-branch) and the two `--plan` lines that gained `config_checks`. In the tests, row 200's fixture lines
-(the loaders, `sso-config.mjs` and the `--sso` cli.mjs line for C1 and C) moved into
-`stack-release-fixture.mjs` with the rest of the copy setup, and the `ALGS` import stays in
-`stack-release.test.mjs`, which T57 uses.

-## duckworth-0055's notes on r6 (brief line 169)
-
-Duckworth's r6 approval (REVIEW-r5.md at 23f5520b5) carried two notes.
-
-- N1, A2's stop timeout under `gate --since`. A unit that never stopped keeps its old `ActiveEnterTimestamp`,
-  so `gate --since` fails it with `stale-start`, and the run ends at exit 2 with root stopping the units.
-  That is intended: a unit that won't stop is a fair reason to stop. In I1 this is the gate code and its
-  polling (`stale-start: @1792540799 fails ...`, `gate (N2, A2f)`, m11). The run sheet's A2f line and the
-  re-pin test that points "exits 1 with OLD's gate passing" at an A3 exit 3 belong to I3, which owns
-  `scripts/stack-upgrade.sh` and `docs/guides/host-run-sheet.md`. I'll name both in the I3 build.
-- N2, the claude path under `/opt/mosaic-stack` (gosalyn-0058, sage-1522). I1 doesn't touch it. Under
-  `--units external` the script checks no claude pin of its own (`no-claude-pin` applies only to user
-  mode), because root's unit carries it. The `--claude` value, the managed-settings reasoning, F6 and the
-  run sheet's claude step go to I2 and I3.
-
-## Run environment
-
-Worktree `/mnt/storage/scratch/darkwing-r232`, `TMPDIR=/mnt/storage/scratch/tmp/r232`, node from PATH.
-One external file run takes about 94 s.
-
-## Results
-
-Singles on the rebased candidate, before the gate:
-
-| File | Tests | Pass | Fail |
-|---|---|---|---|

-| `packages/cli/tests/stack-copy.test.mjs` | 16 | 16 | 0 |
-| `packages/cli/tests/stack-release.test.mjs` (row 200's T57 included) | 192 | 192 | 0 |
-| `packages/cli/tests/stack-instances.test.mjs` | 23 | 23 | 0 |
-| `packages/webui/tests/pinned-copy.test.mjs` | 10 | 10 | 0 |
-| `packages/cli/tests/channel-recovery.test.mjs` (imports `channel-fixture.mjs`, which names the scripts) | 1 | 1 | 0 |
-| `packages/cli/tests/host.test.mjs` (reads `packages/cli/README.md`) | 42 | 42 | 0 |
-
-These are every test file that reads `stack-release.sh` or `stack-copy.sh` (a grep of `packages/*/tests` and
-`scripts/`). None of them pins a sha256 of a changed file. `packages/cli/tests/host.test.mjs` reads
-`packages/cli/README.md` for a unit file name; this row only adds a paragraph there. The grep and the runs
-were repeated on the rebased tree on 2026-10-21; the reader set is the same. A dry run of `mutants.sh`
-matches each of the 17 replacements once on the rebased scripts.
-
-### Gate, 2026-10-21, Sage's slot (sage-1618)
-
-Candidate a0ffabc3f on `darkwing/row232-r1`, run by `~/darkwing-scratch/r232/gate.sh`: the cli suite, then
-every `scripts/test-*.sh`, one after another, stopping at the first failure. busy.sh passed at 01:07:49Z
-after Launchpad's single `stack-release.test.mjs` run ended. The gate stopped at the first one, so the
-chain waited for that PID to exit and checked again. The EXIT trap removed the compose network; no
-container was left.
-
-| Step | Time (UTC) | Result |
-|---|---|---|
-| `packages/cli`, `node --test tests/*.test.mjs` | 01:07:50 to 01:17:53 | 561 pass, 0 fail, 0 skipped |
-| `scripts/test-auth.sh` | 01:17:53 to 01:17:54 | 15 passed, 0 failed |

-
-### Mutants, 2026-10-21, same slot
-
-`~/darkwing-scratch/r232/mutants.sh`, right after the gate. Both controls (the external file whole, and
-stack-copy's `^row 232: ` tests) exited 0 on the unmutated tree. Each mutant was applied after a checked
-backup and a syntax check, ran its killers from the table above, and was put back with its sha256
-checked. The script stops on any restore mismatch, and it ran to its end.
-
-| Mutant | Killer exit | Result |
-|---|---|---|
-| m01 pointer on gate failure | 1 | killed |
-| m02 gate once | 1 | killed |
-| m03 PM from any instance | 1 | killed |
-| m04 no startedAt check | 1 | killed |
-| m05 newest marker | 1 | killed |
-| m06 --to not compared | 1 | killed |
-| m07 one call without --user | 1 | killed |
-| m08 interim pending line | 1 | killed |
-| m09 marker written last | 1 | killed |
-| m10 refusal names the open activation | 1 | killed |
-| m11 stale-start refuses | 1 | killed |
-| m12 revert always restores | 1 | killed |
-| m13 confirm op | 1 | killed |
-| m14 MIGRATING after migrate | 1 | killed |
-| m15 gate floor from the log | 1 | killed |
-| m16 bundle reachability unchecked | 1 | killed |
-| m17 --create overwrites | 1 | killed |
-
-17 of 17 killed, 01:22:16 to 01:24:32Z. I read the logs for m01 and m09, two of the quick kills: each failed on
-its named test's assertion (m09 on `AWAITING-UNITS` in sequence 2), not on a load error.
-
-## Round 2: rebase onto 8fede5fc6 (sage-1673)
-
-Rebase only. Before the landing gate, a check of BASE..HEAD on the manifest paths found that row 230
-(c8bc5cf4c) had changed one of them after the round 1 base, cb5fdb064. Sage ruled a re-round with a
-scoped review, the same shape as row 210 round 3.
-
-Branch `darkwing/row232-r2`: the two round 1 commits, a0ffabc3f and 84f1a91e6, cherry-picked onto
-8fede5fc6 with no conflict, then this section. No code or test changed.

-
-Brief: `docs/plans/2026-10-20_installer-rows.md` section I3, blob `e61291bcf1c6` (commit a0e3d7cfd), re-pinned
-by Sage (sage-1685, rev 2631) from `f35e7e57daee` (ad6f0be7a). The later blob only appends I4; the I3 text
-is the same. Gitea #1735, Vikunja P19

-differ, the brief wins. Sage's rulings during the build: sage-1650 and sage-1652 (`--backup last`, the

-- `scripts/stack-upgrade.sh` (new): `upgrade` and `rollback`, root's side of r6 A1-A5, A2f and R1-R4.
-- `packages/cli/tests/stack-upgrade.test.mjs` (new, 20 tests).
-- `docs/guides/host-run-sheet.md` (new).
-- `docs/TOOLS.md`: a new subsection "Root's upgrade driver (`scripts/stack-upgrade.sh`, row 233)", plus the
-  row 232 lines below.
-- Row 232 files, changed on Sage's rulings (the brief's files list doesn't name them):
-  - `scripts/stack-release.sh`:
-    - `rehearse --backup last` takes the newest backup the log records (`from_log newest`) and prints
-      `PASS backup-last`. With none it fails `no-backup`, exits 3 and makes no rehearsal directory.
-      A newest backup that isn't an activation id aborts `backup-unreadable`, exit 1.
-    - The rehearsal prints `BACKUP_STORE <activation id> schema <version>` before its migration step.
-    - `--plan` under `--units external` refuses `open-activation` when any rollback set holds
-      `AWAITING-UNITS`, and `migrate-required` for a migrating target without `--migrate`. Root reads
-      only the plan's exit, so these two have to be refusals there. User mode prints the same bytes.
-  - `packages/cli/tests/stack-release.test.mjs`: three new `row 233:` tests for `--backup last`.
-  - `docs/TOOLS.md`: `--backup ACTIVATION|PATH|last` in the rehearse usage, a paragraph on `last`, and a

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

-Filbert's row 233 approve (Gitea 29922) left five notes. Sage ruled N1, N4 and N5 into this row and N2 and N3
-to DEFERRED.md (sage-1727).
-
-| Note | Change |
-|---|---|
-| N1: `stack-upgrade.sh` exits 1 `args-failed` when the args move after A5 fails, but exit 1 means the old copy runs | The move's failure exits 5 `args-failed`. The header, TOOLS.md's step 5 and exit line, and run sheet section 6's exit list name exit 5 and what root does: move the new file the result line names into place. Test `row 240: I3 N1: a failed args move after A5 exits 5 ...` makes `/etc/mosaic-stack` read-only at confirm and checks exit 5, the step names, `args rc=1`, the result line, both units on the new copy, the old args file's bytes and the new file beside it. The step log regex takes `exit=5`. Mutant M8. |
-| N4: section 3's `npm install` has no npm on root's PATH, and the `--claude` path is unnamed while `node_modules/.bin/claude` is a symlink `case2-unit.sh:140` refuses | The install line runs with section 2's pinned node first on PATH (the postinstall runs `node` too). The `--claude` path is `node_modules/@anthropic-ai/claude-code/bin/claude.exe`, and a `--version` line catches the postinstall's 500-byte stub. |
-| N5: sections 8 and 10 lack precheck lines | Each gets "Precheck line: none" and its missing line. |
-
-Exit 5 is new rather than 2 because 2 means both units are stopped, and here both run. Exit 4 stays usage.
-
-The `claude.exe` path comes from the 2.1.304 package itself: `npm view` gives `bin.claude` as `bin/claude.exe`,
-and its `install.cjs` hardlinks the platform binary over that placeholder, or copies it across devices, then
-sets 0755. I downloaded the tarball into `/mnt/storage/scratch/tmp/r240/cc304` and read it; nothing ran. The
-run sheet says a newer pin needs the same check.

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

-## Run environment
-
-Worktree `/mnt/storage/scratch/darkwing-r240b`, branch `darkwing/row240-r3` on c771a36f4, with `node_modules`
-linked to the canonical checkout's. Node v26.8.1, kernel 7.2.2-1-cachyos, 16 CPUs, TMPDIR
-`/mnt/storage/scratch/tmp/r240`, compose project `darkwing-r240b`. Sage's slot (sage-1773, 06:16Z). Each run is
-one chain behind `busy.sh`, launched from `/`: `~/darkwing-scratch/r240/run-all.sh` checks the HEAD pin and a
-clean tree, runs the singles, then the mutants (8 killed, none surviving, the tree clean after), then the gate
-(the cli suite and every `scripts/test-*.sh`), each stopping the chain on failure, then sweeps `/proc` cwd links
-for anything left in the r240 trees.
-
-## Results
-
-Run r1, 06:17:10Z on 47ec9fe2f, failed at the singles. `case1-hostcheck.test.mjs` passed 16/0/0, and
-`stack-upgrade.test.mjs` went 20 pass, 1 fail. The failure was the N1 test's own `t.after` hook, which ran
-`chmodSync(e.etc, 0o755)` after the fixture's cleanup had already removed the scratch root, so it threw ENOENT.
-Every assertion in the test body had passed, exit 5 included. The fixture's cleanup runs `chmod -R u+w` on the
-root before `rmSync`, so the 0555 dir never needed the hook. b45852daa drops it and changes nothing else. The
-mutants and the gate didn't run. The sweep found nothing left. Sage counted r1 as this slot's one failure
-(sage-1788).
-
-Run r2, 06:20:41Z to 06:33:28Z on b45852daa, passed. The counts come from awk over the .out files
-(`~/darkwing-scratch/r233/sum.sh`):

-# 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.

-Logs: `/mnt/storage/scratch/darkwing-245-out/` (`step1.log`, `mut.out`, `mut/m1-16.log`, `gate.out`).

-Gizmoduck, 2026-10-21. Reviewer Duckworth, gate owner Sage. Lands by 10-25, before the .53 and .54 installs

-
-## Names: r6 against section 7
-
-r6's `grant.*` and `host.enroll.*` names are `body.action` values on `action.allowed` events, not event
-kinds. The `events` kind CHECK isn't rebuilt. Four r6 names move under `grant.`:
-
-| r6 | This row |
-|---|---|
-| `host.enroll.step` | `grant.host.enroll.step` |
-| `host.enrolled` | `grant.host.enrolled` |
-| `host.checked` | `grant.host.checked` |
-| `host.removed` | `grant.host.removed` |
-
-Only the consume record carries `decision`: `{operation: 'grant.host-enroll', decision}`. Every other
-guarded body names the decision `grantDecision`, so r6's `decision` field in step, enrolled and failed bodies
-is `grantDecision` here. The actor of every guarded event is `actor_role` NULL with `actor_run` 'grant',
-and `body.by` names the caller the broker checked.
-
-## Split (r6 section 12 Q-S4)
-
-Row a builds:
-
-1. **Schema 3i to 3j.** `migrations/3i-3j.sql` adds `hosts` and `host_grants` (r6 S1, primary keys
-   (business, host) and (business, agent, host)) and the guard trigger: an `action.allowed` whose
-   `body.action` or `body.operation` GLOBs `'grant.*'` aborts unless the actor is (NULL, 'grant').
-   `SCHEMA_VERSION` 3j, a migration test with a step that fails partway.
-2. **Grant event writer.** A private session-less broker writer for guarded events. `#event` doesn't change.
-   `recordEvent` refuses `reserved-event` for the guarded namespace.
-3. **The `grant` raise frame.** `decision.raise` takes `grant` only with `credential.mint`, only from the chief
-   (`grant-chief-only`), and in row a only with `method: 'host-enroll'`. Any other method refuses
-   `invalid-request` until row b adds `host`. E1's checks, the `ssh-keyscan` set compare before the raise
-   transaction, and the rendered block.
-4. **Enrollment executor.** `#consumeGrant`, the start on the human's cli yes (X1), E2 steps 1 to 4, the
-   installer key at `<configDir>/secrets/hosts/<business>/<hostId>/installer`, the failure cleanup, and the
-   start reconcile for enrollments: the `registry` step undo, and a resolved-yes unspent enrollment ending
-   `grant.failed interrupted` (X3).
-5. **`hosts.check` and `hosts.remove`** (E4), with `mosaic hosts status|check|remove`.
-6. **`tools/host/`**: `mosaic-keys`, `mosaic-keys-write`, `mosaic-keys.sudoers`, `mosaic-keys.sshd.conf` (E3).
-7. **`host.run` on the store** (X4 first and third bullets): it reads the `hosts` and `host_grants` records
-   and the Approve record check, and at start the runtime gives `Credentials` a reference per `host_grants`
-   record. The loader refuses `hosts` at the top level and in a role (S1). Row 210's tests move to store
-   fixtures.
-8. **Reader filter** (duckworth-0067 N1): every grant-evidence reader in this row (status, the start
-   reconcile, `openGrantDecisions`) filters `kind = 'action.allowed' AND actor_role IS NULL AND actor_run =
-   'grant'`, with a test that an `action.refused` look-alike and a session-written one are ignored.
-   `hosts.remove`'s `hostLineLeft` reader is one of them (duckworth-0079 M4).
-
-Row b keeps the `host` method's raise binding (R4), the grant executor (X2), the grant rows of X3, X5,
-`Credentials.register`/`claim`/`abortClaim`, revoke (section 6) and `sweep`. So row a has no way to make a
-`host_grants` record outside a test fixture, and from its landing to row b's no agent holds a host grant
-(r6 N9, the run sheet strips row 210's keys).
-
-Tests in row a (r6 section 10): G1 and G5 for the `host-enroll` raise, G6 and G10 for the enrollment
-executor, G11's enrollment cases, G14, G15, G16, G17, G18, G20, G21 (its `host-line-left` case reads an
-event fixture until row b writes `hostLineLeft`), G25, the migration test, the trigger cases, the reader
-filter test, and row 210's T-tests on store fixtures. Row b: G2 to G4, G7 to G9, G11's grant cases, G12,
-G13, G19, G22 to G24, G26 to G28.
-
-## Early check items (duckworth-0079, REVIEW-build-split.md 10672772e on `duckworth/reviews`)
-
-Moves into row a:
-- M1. G4 for the `host-enroll` block (r6:240-242): a question can't forge the block, and the 4096-character
-  limit holds with the block appended. G4 for the `host` block stays in row b.
-- M2. The tag function (r6:265-266), because E2 step 2 tags the installer line. G24's first sentence moves
-  here: names of 64 characters with `.` and `_` give distinct tags of the fixed length. The `sweep` half
-  stays in row b.
-- M3. A store-fixture test that `host.run` refuses `host-not-granted` for no record, an unresolved decision,
-  a decision resolved by an arbiter, the tester or an agent or not via cli, a consume record with operation
-  `grant.host-enroll` in place of `grant.host`, and an unspent decision (X4 first bullet, r6:593-596). A
-  restart test that a `host_grants` fixture gives `Credentials` a reference (X4 third bullet).
-
-G21's `host-line-left` case:
-- F1. The fixture goes through this row's private grant writer in the real shape: `action.allowed`, actor
-  (NULL, 'grant'), `body.action` 'grant.failed', `body.host`, `body.hostLineLeft`. No raw SQL around the
-  trigger.
-- F2. `hosts.remove` reads `body.hostLineLeft` from any guarded body, not only `grant.failed`.
-- F3. Decided: a guarded body that carries `hostLineLeft` also carries `host`. Row b adds `host` to
-  `grant.revoke.closed`, so its body is `{tag, host, hostLineLeft}` (r6:716 has `{tag, hostLineLeft}`).
-  The reader matches on `body.host`, and doesn't map tags back to hosts through `grant.step`. A direct
-  field is one equality in SQL, and a tag lookup would add a second reader that the N1 filter also has to
-  cover.
-- F4. Row b carry: "no later `sweep` cleared it" (r6:403) needs `grant.sweep`, which only row b writes. Row
-  b adds the sweep clear to `hosts.remove` with a G21 case, and its G8 or G13 shows `hosts.remove`
-  refusing after a real `hostLineLeft` write, not only after the fixture. Until then row a's check is "any
-  guarded `hostLineLeft` for this host refuses".
-

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 |

-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.

-## 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/mosaic runs the `library survey` exec block before the case line, and the case line keeps `credentials`.

-# Row 242 build: a retry after publish-timeout pushes once
-
-Row 242, #1748, P19 440. Brief: docs/plans/2026-10-20_agent-credentials.md, "Brief: row 237
-follow-up N1, a retry after publish-timeout pushes once" (9d165be8c). Base: origin/refactor
-8fede5fc6 (row 210 landed f5753c0e8).
-
-## The defect
-
-The git socket polls publishResult until publishDeadlineMs, then refuses publish-timeout
-(packages/cli/src/git-socket.mjs:433) while the bus process's push (runtime publishPush) can
-still be running. The socket then calls publishRefused, which went straight to
-broker.publishRefused: it filed the refusal and deleted the ticket. checkPublish no longer saw an
-open ticket on the decision, so a retry got a new ticket and pushed a second ref while the first
-push was still on its way to the fork.
-
-## Fix chosen: hold the decision until the push ends, then record a push that reached the fork
-
-packages/bus/src/runtime.mjs, `publishRefused` and `settle`:
-
-- If the bus has no push for the ticket, publishRefused goes to the broker as before.
-- If the push is still running, the refusal code is held on the entry and the ticket stays open.
-  checkPublish refuses another publish on the decision with publish-busy (row 237's check),
-  the same as when the socket is still polling.
-- When the push ends, `settle` runs:
-  - A push that reached the fork is recorded with broker.recordPublish, which spends the
-    decision. The bus logs `pushed after the git socket refused <code>; recorded`.
-  - A push that failed is filed as publishRefused with the socket's code.
-  - If recordPublish refuses with a BusError, that code is filed instead.
-- If the push has already ended when the refusal arrives, it's settled at once. The sage-1440 test
-  relies on this: its push fails fast, so publish-timeout is filed once, immediately, as before.
-
-Why hold rather than kill. Killing the git client doesn't undo a push the fork has already
-received: receive-pack can update the ref after the client dies. After a kill the bus would have
-to ls-remote the fork to learn what landed, and the result could still race the server. Holding
-waits for the push's own outcome. Each git run in publishRemote already has its own limit
-(publishRemote defaults to checkout.mjs GIT_LIMITS), so a hold is bounded. Holding also reuses the existing publish-busy
-state, and the refusal text is unchanged.
-
-Why record and not only hold. If the hold just filed publish-timeout once the push ended, the
-ticket would close and the decision would be free again with a ref on the fork. A retry would then
-push a second ref. Recording the late push spends the decision, so the retry gets
-decision-consumed.
-
-The publish-timeout refusal text is unchanged (brief condition).
-
-## Test
-
-packages/cli/tests/publish-socket.test.mjs:302, "row 242: a retry after publish-timeout refuses
-publish-busy while the bus process's push runs; the late push is recorded and the decision pushes
-once".
-
-- publishDeadlineMs 150 and a store token. The fork's pre-receive hook writes `held`, then loops
-  until the test writes `release`.
-- The first publish gives publish-timeout. The test waits for `held`.
-- A retry to branch `other` gives publish-busy (:322). Refused events: ["publish-busy"]. No
-  git.push.remote allowed event.
-- The test writes `release` and waits until there is exactly one allowed event, with ref
-  refs/heads/coder/feat and the work commit.
-- The next retry gives decision-consumed (:330).
-- Exactly one git-receive-pack request reached the fake Gitea, and the fork has only
-  refs/heads/coder/feat. Refused events: ["publish-busy", "decision-consumed"]. No TOKEN appears in
-  events or logs.
-
-Fail fast (sage-1681): the body is wrapped in try/finally, and the finally writes `release`. Under
-the first mutant run, the assert at the retry failed and the hook was never released. setup's
-teardown waits for the fake Gitea, which waited for the held push, so the file hung until I stopped
-it. Now a failed assert ends the hook and the run. Each wait is bounded at 10 s with an assert.fail.
-
-## Mutants
-
-Script: /mnt/storage/scratch/megavolt-r242/mutants.sh. Each mutant: save, one-line sed, run
-publish-socket.test.mjs whole, restore, cmp.

-| Mutant | Change | Expected kill |
-|---|---|---|
-| M1 | export `publishRefused: (ticket, args) => broker.publishRefused(ticket, args)` again (removes the fix) | :302 at :322: the retry gets a new ticket and its own push, so publish-timeout, not publish-busy (seen in the stopped 03:06Z run) |
-| M2 | `settle` files publishRefused without trying recordPublish (hold only) | :302 at the wait for one allowed event, then :330 |

-(cmp ok).

-- M2: publish-socket 8/1, the row 242 test fails at :327, the wait for one allowed event, through

-and scripts/test-*.sh are left for Sage's landing gate.
-
-## Residuals
-
-- The agent was told publish-timeout, but the push is recorded later and the run isn't
-  notified. The allowed event and the bus log line are the only trace. A later publish on the
-  decision gets decision-consumed, which tells the agent the decision was used. Whether the run
-  should get a RESULT for a late record is a follow-up question for Sage.
-- A late push whose recordPublish refuses (Duckworth N2) is filed with that code: the ref stays on
-  the fork and the decision is not spent, the same residual as an in-band push whose record
-  refuses.
-- The hold lives in the bus process's memory, like the broker's open tickets. A bus restart during
-  a hold drops both, the same as today for any publish in flight.

-Morgana (Opus 5.5), 2026-10-20. Queue row 213, Gitea #1714. Brief: `docs/plans/2026-10-20_case2-rows.md`
-§ C2-08 (on `refactor` from 32b54ac3b). Design: Gosalyn's Case 2 design r10, sections 4 and 5.

-
-## What it is
-
-1. **Six creative roles** (`roles/<name>.json` and `.md`, roleVersion 2): companion and research get
-   read and web, with network api-only. ideas, proofreader, fact-checker and continuity get read only, with
-   network none. All six get withinRole `["message.send"]`, no credentials, and messaging that sends to and
-   receives from `human` only. `vocabulary.mjs` names them in `CREATIVE_DEFINITIONS`, plus `CREATIVE_KINDS`,
-   `CREATIVE_TOOLS` and `THREAD_DEFINITIONS`. `END_PROTECTED` becomes `THREAD_DEFINITIONS`.
-2. **M1** (`role.mjs` `checkCreative`): a creative role file is refused if it names a tool outside
-   `CREATIVE_TOOLS`, holds any authority but withinRole `message.send`, lacks `messaging`, names anyone but
-   `human` in messaging, or is version 1.
-3. **M2**: since the role files name no write, edit or bash tool, the existing gate refuses write, edit and
-   bash on pi and Write, Edit and Bash on claude-code for each creative role. No gate code changed. The
-   test pins it.
-4. **M6**: `tools.mjs` leaves `raise_decision` out for a creative definition. `broker.mjs` refuses
-   `decision.raise` from a creative session with `decision-not-allowed`, after `#secretCheck` and before
-   the spec-cited path, so a cited raise is refused too.
-5. **M10**: a creative instance belongs to the human.
-   - `launch-settings.mjs` `creativeHumanOnly` gives `organization-creative-human-only` to any other actor.
-     It covers: a `models` key that a creative instance's `model` or `fallback.model` var names (changed or
-     removed), `setRoutes` for the instance, and the `instances` key. The `instances` key is refused for
-     every actor with `organization-creative-instance`, because the model changes through `instances.set`
-     or `routes.set`.
-   - `instance-settings.mjs`: add, change and redefine to or from a creative definition are the human's.
-     A creative definition is `END_PROTECTED`, so the new `closed()` lets this writer still add and change
-     one. `accepted` and `protected` use `closed()` too, so the human's Console form offers the creative
-     definitions and marks those instances as editable.
-6. **Persona** (design 4): vars `persona.name` (one line, max 40) and `persona.sha256` (64 lowercase hex),
-   agent layer. The file lives at `<configDir>/personas/<business>/<instance>.md`.
-   - `bundle.mjs` `readPersona` opens it with O_NOFOLLOW and refuses with `persona-invalid` when the file
-     is missing, a symlink, not a regular file, owned by another uid, carries group or other mode bits, is
-     over 8000 characters, is not UTF-8, or holds `</persona-file>` or a line starting `# ` or `## `.
-   - It refuses with `persona-mismatch` when the bytes don't match the digest.
-   - A file present with no `persona.sha256` var is ignored. A digest with no `personaDir` refuses.
-   - The block sits between the contract and `## This session`, wrapped in
-     `<persona-file instance=... sha256=...>`.
-7. **Web**: `webPlan` refuses `web-source-not-allowed` when a creative definition is on
-   `harness-builtin`, so every creative fetch goes through the broker.
-8. **Prompt by file**: claude passes `--system-prompt-file <path>`, and pi passes `--system-prompt <path>`.
-   Both make the path absolute. The prompt text no longer appears in `/proc/<pid>/cmdline`.
-   `adapters/README.md` says so.
-
-## Refusal codes
-
-`persona-invalid`, `persona-mismatch`, `web-source-not-allowed`, `organization-creative-human-only` and
-`organization-creative-instance` are new. `decision-not-allowed` is named in the brief but is also new in
-code. My morgana-0021 message called it an existing code, which was wrong.
-
-## Deviations (sage-1492)
-
-- **D1** `packages/business/src/business.mjs`: `checkPersonaVars`, plus one call line at the end of
-  `checkRoles`'s per-instance block. The persona vars are accepted only on an instance of a creative
-  definition, and only both together. Without D1, any instance's agent layer could carry a persona
-  digest, and the bundle would read a persona file for a pm or chief.
-  Test: `business.test.mjs` "persona vars: agent layer, creative definition only, both or neither". It
-  covers the business layer, pm and chief, one key alone and malformed values. `instance-settings.test.mjs`
-  also covers it: changing a persona-carrying companion to security-reviewer is refused.
-  Mutants: D1a, D1b, D1c.
-- **D2** `packages/cli/src/launcher.mjs`: one line, `personaDir: join(configDir(env), "personas"),` in the
-  `buildBundle` call. Without it a creative instance with a persona can never launch.
-  Test: `launcher.test.mjs` "row 213 a creative instance's persona is read from <configDir>/personas: off
-  its digest the launch fails with the mismatch as its reason". Mutant: D2.
-
-- **Adapter tests' file** (webby-0040 N1). Brief line 68 puts the adapter tests in `claude-session.test.mjs`
-  and `pi-session.test.mjs`. They are in `harness/tests/creative.test.mjs` instead, next to the other row 213
-  harness tests, so the row's adapter cases sit in one file and the two session test files stay unchanged.
-  Same cases: argv holds the absolute prompt path and no marker, and pi refuses a missing, unreadable or
-  directory prompt.
-
-The checkRoles change sits in its own block and the launcher change is one line, so the rebase over rows
-194 and 199 (both touch `business.mjs`, and 199 touches `launcher.mjs`) stays small.
-
-## Pinned-test edits and the pi tightening (sage-1492, named here)
-
-1. `packages/bus/tests/project-runtime.test.mjs:26`: the pinned broker import line gains
-   `CREATIVE_DEFINITIONS` (M6 reads it).
-2. `packages/harness/tests/skills.test.mjs:170`: the test checked the prompt text in argv after
-   `--system-prompt`. Each adapter now passes a path, so the test looks up the flag for each harness,
-   checks that the next argument is the bundle's prompt file, and reads the MARKED and chief checks from
-   that file.
-3. `adapters/pi/adapter.sh`: `[ -f "$PROMPT_FILE" ] && [ -r "$PROMPT_FILE" ]`, exit 2 otherwise. Pi 0.85.1
-   uses the path string as the prompt when it can't read the file. Test: `harness/tests/creative.test.mjs`
-   "pi refuses a missing, unreadable or directory prompt" (pi never runs). Mutant: A1.
-
-One more pinned assertion changed: `business/tests/assistant.test.mjs` REQ-HARN-2 expected only the
-assistant to hold `web`. Companion and research now hold it too.
-
-## Files
-
-Source: `packages/business/src/{vocabulary,role,vars,business,launch-settings,instance-settings}.mjs`,
-`packages/harness/src/{bundle,tools}.mjs`, `packages/bus/src/broker.mjs`, `packages/cli/src/launcher.mjs`,
-`adapters/{pi,claude}/adapter.sh`, `adapters/README.md`, `roles/{companion,research,ideas,proofreader,
-fact-checker,continuity}.{json,md}`.
-
-Tests changed: `business/tests/{role,business,launch-settings,instance-settings,assistant}.test.mjs`,
-`harness/tests/skills.test.mjs`, `bus/tests/project-runtime.test.mjs`, `cli/tests/launcher.test.mjs`.
-New: `harness/tests/creative.test.mjs` (7), `bus/tests/creative.test.mjs` (3).
-
-I grepped `packages/*/tests` and `scripts/` for each changed source path next to a 64-hex string. The hits
-are `thread-migration.test.mjs` (a DDL digest, not a pin on `broker.mjs`; 3/3 pass) and discord's own
-`tools.mjs`. No test pins a changed file.
-
-## Evidence
-
-Each file alone from its package with `node --test --test-reporter=tap <file>`, 2026-10-20, all fail 0:
-
-- Touched: business role 17, business 17, launch-settings 16, instance-settings 12, assistant 11; harness
-  creative 7, skills 10, bundle 22; bus creative 3, project-runtime 3; cli launcher 30. Round 2 reran
-  bus creative, instance-settings, business, launch-settings, role, harness creative and bundle, bus
-  tester-writes 8 and chief-of-staff 18, and the vars readers business vars 7, discord context 7 and git 12.
-- Other files that read a changed path: business hard-waits, record-grants, token-limit-settings,
-  workflow-roles, chief-of-staff, project-repo, plugin-settings; harness bundle 22, tools 22,
-  claude-session 8, pi-session 8, raise-domain, spec-tools, claude-gate, mcp-server, gate, runner 34,
-  git-tools; bus hard-waits, launch-notice, tester-writes, business, broker 16, workflow-roles, web 19,
-  task-page, thread-migration 3; discord git, web, setspark, engine, tools; plugins harness, loader; seat
-  working, sandbox, session; cli launch-limit-checks, limits, git-socket, launch-account, thread-launch,
-  launch-limits, launch-routes, instances, stack-copy, stack-release 174; webui limits-browser, editor,
-  settings-form, tester-browser.
-
-Suites, `scripts/test-*.sh` and the mutants are not run yet. They need Sage's slot.
-
-Drift: `git diff --stat 088087ac9 305857c8f` over the 35 manifest paths is empty (2026-10-20, sage-1501).
-Row 192's async `scripts/mosaic-config.mjs` and `webui-service.sh` are outside the manifest. The broker's
-new import comes from `vocabulary.mjs`, which it already imported, so `RUNNER_FILES` doesn't change.
-
-Mutants: `mutants.py` in this directory, 31 mutants over 11 files. It backs up each file to scratch first,
-aborts on a bad backup or any anchor count other than one (all 31 checked as unique without editing), runs
-the named test files per mutant, restores each file after its mutant and again in `finally`. Log:
-`mutants.log`, written on the run. The brief's `models` mutant is L1.

-
-## Residuals
-
-- `ID_PATTERN` allows dots, so a human id could read like `<definition>.<instance>`. That is only cosmetic:
-  `creativeHumanOnly` compares the actor with `document.human`.
-- TOCTOU between pi's `[ -f ] && [ -r ]` and pi's own read of the bundle's prompt file.
-- The other-uid owner check in `readPersona` can't be tested without root.
-- O_NOFOLLOW covers only the last path component, so a symlinked `personas/` or `personas/<business>/` is
-  followed (webby-0040 N2). The digest still refuses any bytes but the pinned ones. A comment in
-  `bundle.mjs` says so.
-- The claude adapter checks the prompt file with `[ -r ]` only, and pi checks `-f` and `-r`. The brief asks
-  for pi's check (webby-0040 N4).
-- **Launch-failed mapping.** A BundleError thrown from `buildBundle` inside `start()` becomes the Refusal
-  `launch-failed`, with the code's message in the log's `why`. That holds for the persona codes and for
-  webPlan's `web-source-not-allowed`. By then the run dir `launches/<business>/<run>/` exists with only
-  `session/`, and no bundle is written. Only `check()`'s readSkills preflight surfaces bundle codes. The
-  D2 test pins both facts. I kept the launcher change to one line, as sage-1492 asked.
-
-## Follow-ups (not in this row)
-
-- A persona preflight in launcher `check()`, so a bad persona refuses with its own code before a run dir
-  exists. Sage agreed it as a follow-up (sage-1501) and files it after this row lands.
-- The webui `bus.mjs` code-to-HTTP map lacks the new codes.
-- webby-0053 N1: `checkCreative` doesn't refuse `credentials`, so a later role-file commit could give a
-  creative instance a gitea credential. All six creative role files have `credentials: []` today. A
-  one-line refusal and a `role.test.mjs` case close it.
-- The cli `instances.mjs` message wording for the creative refusals.
-
-## Round 2 (webby-0040, round 1 CHANGES on bb5f4600)
-
-- **B1**: `bus/tests/creative.test.mjs` adds "M10 through the broker". It runs on a real organization file
-  and writer behind `startBroker`, with a claimed chief session, a bound tester session and the human.
-  - The chief's `organization.set` of bean's `launch.models` key is refused with
-    `organization-creative-human-only`. Its `instances` key is refused with `organization-creative-instance`.
-  - The tester's `organization.set` and `limits.set` are refused `tester-refused` (N5: the broker refuses
-    first). Its `instances.set` (change bean, add an ideas instance) and `routes.set` for bean reach the
-    writer as `tester` and are refused with `organization-creative-human-only`.
-  - The file bytes are unchanged and no committed log entry exists after all of these.
-  - The human's `limits.set` of the same change lands, and the one committed entry names `jason`.
-  - Mutants K2 and K3 change the broker's actor naming for a role or tester session.
-- **B2**: `instance-settings.test.mjs` asserts the mode of `writer.logFile("acme")` (0600) and that it sits
-  in the history dir. It lives at `.history/acme/changes.jsonl`, so the round 1 loop over that dir already
-  covered it, but no line named it.
-- **N1**: listed under Deviations. **N2**: comment and residual. **N3**: `persona.name` now refuses U+2028
-  and U+2029, with two values added to the business test and mutant V1. **N4**: noted under residuals.
-
-- Drift: `git diff --stat 088087ac9 f41729178` over the 35 manifest paths is empty. Round 2 manifest
-  digest b5ff0ac0e754cb1e5891417f4ab1da9597f5cf49fb2fe2d5f0fbf066f821c43a.
-
-## Round 3 (sage-1715): rebase onto 9b5362018
-
-Rows 199 (cb5fdb064), 237 (d7d943199) and 210 (f5753c0e8) landed on six manifest paths after the round 2
-approval. Round 3 rebases the three commits onto origin/refactor 9b5362018 on a new branch,
-`morgana/row213-r3`. The round 2 branch stays as it was. Nothing else changed.
-
-- Five files conflicted. Each resolution keeps both sides:
-  - `bus/src/broker.mjs` and `bus/tests/project-runtime.test.mjs`: the vocabulary import keeps rows 199
-    and 210's names (forkProblem, forkUrl, credentialKind, validArgv, commandAllowed) and adds
-    CREATIVE_DEFINITIONS last. The pinned import line in the test carries the same list. RUNNER_FILES
-    is unchanged, since the import is still the vocabulary file only.
-  - `business/src/business.mjs`: one vocabulary import with row 199's names plus CREATIVE_DEFINITIONS.
-    The `checkRoles(roles, file, rolesDir, business, hosts)` signature is row 199's. `checkPersonaVars`
-    runs after row 199's identity and publish checks.
-  - `business/src/role.mjs`: the import keeps row 210's HOST_SERVICE and adds CREATIVE_DEFINITIONS and
-    CREATIVE_TOOLS.
-  - `business/src/vocabulary.mjs`: the creative constants and `END_PROTECTED = THREAD_DEFINITIONS` come
-    before row 199's Gitea URL parse, which is kept whole.
-- `cli/src/launcher.mjs` merged without a conflict.
-- `git range-diff 088087ac9..aee32d185 9b5362018..morgana/row213-r3`: commits 2 and 3 are `=`. Commit 1
-  differs only in the conflict hunks above.
-- None of the new base's added lines name END_PROTECTED, THREAD_DEFINITION, CREATIVE_* or the creative
-  refusal codes, apart from docs. All 31 mutant anchors still count 1. The hash-pin grep finds no
-  64-hex pin on a manifest path.
-- The manifest is rebuilt from the round 3 tree. It has the same 35 paths, and six digests changed: the
-  six drifted files. `base.txt` is 9b5362018.
-- Singles of every touched test file, plus the seat sandbox and bus project-runtime tests (RUNNER_FILES
-  rule), wait on Sage's slot. They are recorded here when run.
-
-## Round 4 (sage-1778, mos-1160): one commit on row 234's landing c771a36f4
-
-Row 234 landed as c771a36f4 after the round 3 approval (webby-0053). Round 4 is one commit on c771a36f4,
-on the new branch `morgana/row213-r4`. It is the round 3 change applied onto the landed blobs. The round 3
-branch stays as it was.
-
-- Overlap, `git diff --name-only 9b5362018 c771a36f4` against the round 3 paths: `business/src/business.mjs`,
-  `bus/src/broker.mjs` and `bus/tests/project-runtime.test.mjs`. Each starts from the landed blob, and the
-  row 213 edits are merged by hand. No landed hunk is reverted (sage-1760).
-  - `broker.mjs` and the pinned `project-runtime` import line: row 234's list with `HOST_ID`, then
-    `CREATIVE_DEFINITIONS`. The test keeps both rows' comments. The import still names only
-    `vocabulary.mjs`, so RUNNER_FILES is unchanged.
-  - `business.mjs`: row 234's import (no `HOST_PREFIX`, no `hosts.mjs`) plus `CREATIVE_DEFINITIONS`.
-    `checkPersonaVars` sits before row 234's `HOSTS_MOVED` and its four-argument `checkRoles`, and still
-    runs after the identity and publish checks.
-- Check: the removed and added non-packet lines of `diff c771a36f4..r4` and `diff 9b5362018..2d2ad2760`
-  differ only in those three import lines. All 31 mutant anchors count 1.
-- Row 234's hosts verbs: `#hostsCaller` admits the human, the tester or the chief definition
-  (`grant-chief-only`), so a creative role can't reach them and M1 stays as narrow.
-- The manifest has the same 35 paths. The three overlap files changed digest. `base.txt` is c771a36f4.
-- Singles and the 31 mutants wait on Sage's slot. They are recorded here when run.

-#### Root-owned units (`--units external`, row 232)
-
-On a host whose bus and Console are root's system units, the stack user runs
-`stack-release.sh` with `--units external` from its own clone of the release
-bundle (sage-1561). The script then calls `systemctl show`, `is-active` and
-`list-units` without `--user` and reads no journal. It starts, stops and
-installs nothing. Root does those steps, and the I3 driver calls the verbs
-below in order. Without `--units`, every command line and every byte of
-output is what it was before row 232. `confirm`, `revert`, `gate`, `--to`
-and `--expect-from` are usage errors without `--units external`.
-
-- `adopt`, `status`, `activate ID` and `rollback --to ID` take the flag.
-  `rollback` then needs `--to`, and `--to` must be the copy `rollback` alone
-  would pick from the log, or it refuses `to-not-previous`.
-- `--plan --expect-from OLD` refuses `pointer-differs` when the pointer
-  names a copy other than OLD.
-- `pm-on` and `activate --pm-after-harness` refuse `external-pm`; the PM
-  flag is in root's bus unit. `--pm`, `--tester-port`, the proof flags,
-  `--no-proof`, `--no-send` and `--sso` are usage errors; root's Console
-  unit carries the Console flags.
-- `activate` and `rollback` refuse `units-running` unless both units read
-  inactive or failed and the store is closed. They make the rollback set
-  with an exclusive `mkdir`, write `AWAITING-UNITS` (the target copy) first,
-  capture the pointer, the wrapper and both units' show output and unit file
-  sums, back up and migrate or restore the store, and write the wrapper.
-  They write no pointer and start nothing. The last line says the run is
-  staged and names `confirm`. A failure after the capture writes `FAILED`
-  with its code, logs nothing more and exits 1; the activation stays open.
-- `confirm ID BUSINESS` needs exactly one `AWAITING-UNITS` for copy ID whose
-  activation the log holds open, or it refuses `open-activation`. It gates
-  the start root made and writes the pointer and an `ok` line with the
-  started line's op, from, to and backup.
-  `confirm --rollback OLD --cause A3|A4|A5` gates OLD after root put the old
-  units back and logs `failed` or `gate-failed` with `rollback ok` (exit 1)
-  or `rollback-failed` (exit 2). Either removes `AWAITING-UNITS` and `FAILED`.
-- `revert ID BUSINESS` puts the saved wrapper back and, when the run had
-  started a migration, restores the backup taken before it. It writes no log
-  line and can run again.
-- `gate ID BUSINESS --since EPOCH` gates a copy with no open activation,
-  takes no lock and writes nothing: 0 on a pass, 1 otherwise. EPOCH is root's
-  clock before root started the units.
-
-The gate under `--units external` replaces the journal read. The bus unit's
-`ActiveEnterTimestamp`, in whole seconds, must be at or after the started
-line's second (`confirm`) or `--since` (`gate`); an older start fails
-`stale-start`, so a unit that never stopped can't pass. With the PM on, the
-gate reads `launches list --json` for exactly one live launch of the PM's
-instance (the business's `launch.by`), for this business, whose run started at
-or after the floor. `status` adds an
-`awaiting units:` line for an open activation.
-
-Under `--units external`, `activate --plan` also refuses `open-activation`
-while any rollback set holds `AWAITING-UNITS`, and `migrate-required` when
-the target migrates the store and the run lacks `--migrate` (row 233). Under
-`--units user` the plan's bytes are unchanged.

-
-Root runs it from a root-owned checkout of the reviewed commit, never from a
-copy, because the stack's user can write the copies. Each run needs Mos's go,
-and `--migrate` needs Jason present (decision 96). The host must be prepared
-first (`docs/guides/host-run-sheet.md`). Only the default instance, `dev`, is
-accepted; a named instance's units are a later row.
-
-The unit values come from `/etc/mosaic-stack/dev.args`, which I2's install
-writes: one `case2-unit.sh` argument per line, the serve flags after `--`,
-owned by root with no group or other write, exactly one `--copy`, and that
-copy the one both installed units run. Otherwise the run refuses
-`args-unreadable` or `args-differ`. The driver writes the new copy id into

-
-`upgrade`, in order. Every stack user step runs as
-`sudo -u USER -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin` from the

-
-1. Takes `flock -n` on `/run/mosaic-stack/upgrade-dev.lock` and holds it to
-   the end, rollback included. A second run refuses `upgrade-running`, and
-   a lock it can't open refuses `lock-failed`.
-2. Fetches the bundle's `refactor` into the clone and fast-forwards it to
-   SHA (`fetch-failed`), then `stack-copy.sh copy --bundle FILE SHA`
-   (`copy-failed`).
-3. A1: this checkout's HEAD is SHA (`head-mismatch`), the copy exists
-   (`copy-missing`), `/usr/local/lib/mosaic-stack/hostcheck.sh --check`
-   exits 0 (`profile-drift`, row 240), both units name one copy
-   (`units-unreadable`, `units-disagree`) and it is the args file's
-   (`args-differ`), and
-   `activate SHA BUSINESS --units external --plan --expect-from OLD` exits 0
-   (`plan-refused`, which covers `open-activation`, `migrate-required` and
-   `pointer-differs`).
-4. The rehearsal, `rehearse SHA BUSINESS --backup last --port 7339`
-   (`--rehearse-port`). Exit 0 goes on. Exit 3 means no backup in the log
-   and goes on only with `--no-rehearsal`, logging `rehearsal-skipped`;
-   without the flag it refuses `no-backup`. Exit 0 with `--no-rehearsal`
-   refuses `rehearsal-required`; any other exit refuses `rehearsal-failed`.
-5. A2 stops the Console, then the bus, and waits for both to read inactive
-   or failed. A3 is `activate --units external`, A4 the render with the new
-   `--copy` (which also starts the bus, then the Console), A5 `confirm`.
-   The driver writes the new args file beside the old one before A2
-   (`args-failed`, exit 3) and moves it into place after A5. A failed move
-   exits 5 `args-failed`: the new copy is live and confirmed, the args file
-   still names the old one, and root moves the new file (the result line
-   names it) into place by hand.
-
-A failure in A2 or a stage that exits 3 starts the old units again and gates
-them (A2f). A later failure stops both units, runs `revert`, renders the old
-copy and runs `confirm --rollback OLD --cause A3|A4|A5`. `rollback` is the
-same from A1 on, with `rollback BUSINESS --to ID`, no fetch, no copy and no
-rehearsal; `--restore` and `--events` pass through.
-
-Root reads no output the stack user wrote except exit codes and the
-rehearsal's `BACKUP_STORE` line, which it copies into its log after a match
-against a fixed pattern (`BACKUP_STORE none` otherwise). The step log
-`/var/log/mosaic-stack/upgrade-dev.log`, 0640, gets one
-`<time> <step> rc=N argv: ...` line per step and a last
-`<time> result exit=N <code> <text>` line.
-
-Exit 0 ok, 1 failed with the old stack running and gated, 2 rollback-failed
-with both units stopped, 3 refused with nothing stopped, 4 usage, 5
-args-failed with the new stack live and confirmed. A refusal
-after step 2 leaves the user's clone fast-forwarded and the new copy made. After exit
-2 the activation stays open, so the next run's plan refuses until root
-finishes it.

-Installed from `scripts/case1-hostcheck.sh` as `hostcheck.sh`, with

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

-

-
-Root runs it on the Case 1 host after the install window, from a root-owned
-checkout. It reads the user, home, copy, node, claude and both ports from the
-args file (`/etc/mosaic-stack/dev.args` on .53), which must pass
-`stack-upgrade.sh`'s rules, say `--profile factory` and name `--business`.
-Every command that runs the stack's code runs as
-`sudo -u USER -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin` from `/`.

-`/healthz`, `sudo -l`, `sudo -u jarvis bwrap --version`, `hostcheck.sh
---check`, and node to parse `managed-settings.json` for F9. F9 runs node only
-when `--node` is the `--node-pin` path, and the file and every directory above
-it are root's with no group or other write. The one write is F3's message and
-its reply, and it never opens `claude-session.env`.
-
-It prints one line per check, `<id> <path> <mark> <evidence>`, then
-`count <mark> N` for each mark and a result line. The functional checks
-F1-F11 are `pass` or `FAIL`: both units active as the user, the Console on
-127.0.0.1 only, a tester message to chief answered, `case2-precheck.sh
---profile factory`, the bwrap labels of a live role session, the claude and
-node pins, one live PM launch, the credential file's owner and mode, the
-autoupdater off, no Discord binding. The host paths P1-P11 are `closed`,
-`accepted <ruling>` (Q182, Q183, mos-1096, mos-1101) or `unnamed`, which means

-# Host run sheet: preparing a host for the stack
-
-ops-01 runs this on a fresh host before install (I2), and once per host for enrollment. Jason places the
-credentials in section 9. Brief: `docs/plans/2026-10-20_installer-rows.md`, I3 (row 233, #1735). The
-host design is Darkwing's r6 (`agents/darkwing/work/queue-195/DESIGN.md`, section 2) as the brief
-changes it.
-
-The hosts are .53 (profile `factory`) and .54 (profile `library`). Both get every section unless a
-section says otherwise. Every command runs as root unless it starts with `sudo -u mosaic`.
-
-Each item names the `scripts/case2-precheck.sh` line that verifies it. Install's precheck runs as the
-stack's user with `--business ID --profile factory|library`. Where no precheck line checks an item, the
-item says "precheck line missing", and Gosalyn adds the line to I2. Today's precheck (C2-13a) has these
-gaps; C2-13b adds the library lines (`library.sync`, persona modes, no Discord binding).
-
-## 1. The stack's user and its home
-
-```sh
-useradd --system --user-group --home-dir /srv/mosaic --create-home --shell /usr/sbin/nologin mosaic
-chmod 0700 /srv/mosaic
-install -d -o root -g root -m 0755 /etc/mosaic-stack
-install -d -o root -g root -m 0750 /var/log/mosaic-stack
-```
-
-`mosaic` gets no sudo rule and no supplementary group. Check with `sudo -l -U mosaic` (expect "not allowed
-to run sudo") and `id -G mosaic` (one number).
-
-Precheck lines:
-- `ok      HOME is /srv/mosaic`
-- `ok      sudo -n true fails as mosaic`
-- `ok      id -G prints one group (<gid>)`
-- `/srv/mosaic` at 0700: precheck line missing.

-## 2. node, pinned under /opt

-
-## 3. claude, factory only (.53)
-
-Root installs it under `/opt`, never under the stack's home (this replaces r6's `/srv/mosaic/.local/bin`).
-The pin is 2.1.304 unless the window names a newer one.
-
-```sh
-install -d -o root -g root -m 0755 /opt/mosaic-stack/claude-<pin> /etc/claude-code
-PATH=/opt/mosaic-stack/node-<v>/bin:/usr/sbin:/usr/bin:/sbin:/bin \

-chown root:root /etc/claude-code/managed-settings.json
-chmod 0644 /etc/claude-code/managed-settings.json
-```
-
-Rollback: `rm -r /opt/mosaic-stack/claude-<pin> /etc/claude-code/managed-settings.json`.
-
-Root's PATH has no npm, so the install line puts section 2's pinned node first; the package's postinstall
-also runs `node`. The `--version` line must print `<pin> (Claude Code)`. Anything else means the postinstall
-left its 500-byte stub in `bin/claude.exe` (no native package for the platform, or scripts were off): stop and
-roll back.
-
-The args file's `--claude` is
-`/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe`, the regular file the
-postinstall hardlinks or copies the native binary to. Not `node_modules/.bin/claude`: that is npm's symlink
-to it, and `case2-unit.sh` refuses a symlink, as it does anything that isn't a root-owned regular file outside
-the home. Checked against the 2.1.304 package's `install.cjs`; a newer pin needs the same check.
-
-Precheck lines:
-- `ok      claude replaces its prompt with --system-prompt-file (<n> input tokens)`. It runs the claude the bus
-  unit's `MOSAIC_CLAUDE_BIN` names, so it needs the model credential from section 9.

-## 4. bubblewrap, AppArmor and the drift stop
-
-Both hosts. These are r6's items, unchanged.

-apparmor_parser -r /etc/apparmor.d/bwrap-userns-restrict
-
-dpkg-statoverride --update --add root mosaic 0750 /usr/bin/bwrap
-```
-
-`aa-status` then lists `bwrap` and `unpriv_bwrap` in enforce mode. Install the one profile file, never the
-whole `apparmor-profiles` package, whose 20 other profiles would load at the next boot. Rollback, in
-reverse order: `dpkg-statoverride --remove /usr/bin/bwrap`, then `chown` and `chmod` to the values in
-`bwrap.orig`; `apparmor_parser -R /etc/apparmor.d/bwrap-userns-restrict`, then `rm` it;
-`apt-get remove bubblewrap`.
-
-The no-new-privs test must print `bwrap//&unpriv_bwrap (enforce)`:
-
-```sh
-systemd-run --wait --pipe --uid=mosaic --gid=mosaic -p NoNewPrivileges=yes -p ProtectSystem=strict \
-  -p ProtectHome=yes -p PrivateTmp=yes \
-  /usr/bin/bwrap --unshare-user --unshare-pid --ro-bind / / cat /proc/self/attr/current
-```
-
-The P9 checks: another user's `/usr/bin/bwrap --version` fails with Permission denied, `getent group mosaic`
-lists no member, and `sysctl fs.protected_hardlinks` prints 1. `sysctl
-kernel.apparmor_restrict_unprivileged_userns` prints 1 too (Ubuntu 24.04's default); leave it, so nothing
-else on the host gains user namespaces.
-
-The drift stop (row 240, I4, #1746) goes in last, after the profile and the statoverride. As root, from
-the root-owned checkout of the reviewed commit:
-
-```sh
-install -d -o root -g root -m 0755 /usr/local/lib/mosaic-stack
-install -o root -g root -m 0755 scripts/case1-hostcheck.sh /usr/local/lib/mosaic-stack/hostcheck.sh
-install -o root -g root -m 0644 scripts/case1-pins.sh /usr/local/lib/mosaic-stack/case1-pins.sh
-printf '%s\n' 'DPkg::Post-Invoke { "/usr/local/lib/mosaic-stack/hostcheck.sh --enforce || true"; };' \

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

-proof, where `scripts/testing/gate-lane.sh:3` set 077 for the test steps.
-
-- Change: the test calls `chmodSync(file, 0o644)` after the write, so its result no longer depends on the
-  umask.
-- Sweep: look in `packages/*/tests` for other tests that expect a refusal of a too-open mode set
-  through `writeFileSync` or `mkdirSync`, and fix those the same way. List what the sweep found in
-  BUILD.md, including when it found none.
-- Test: run the file whole twice, once under `umask 022` and once under `umask 077`. Both runs pass.
-- Order: Mos ruled (mos-1162) that this lands after row 197 r6. Then r6's proof runs on the unchanged
-  test, so it shows the umask fix itself works.

-## Gate runs use a fixture pi auth file
-
-The `docs/plans/DEFERRED.md` entry "Gate runs mount the host's pi auth file" (059577886, Webby N4 on the
-row 197 proof driver, traced by Herb in herb-0051) gets its own row here.
-
-- Change: every gate step that reaches Compose gets a fixture `PI_AUTH_FILE`. That covers the
-  `test-task.sh` cases that call `scripts/run-task.sh`, `test-release.sh` through `release.sh`
-  `health_check`, and row 197's lane `cleanEnv` in `scripts/testing/gate-lane.mjs`. Either the suites
-  or the lane's `cleanEnv` can set it.
-- Test: no gate step mounts the host default `/home/jwoltje/.pi/agent/auth.json`. The test reads
-  the Compose arguments or the environment that each step passes. It does not read the host file.
-- Not in scope: `compose.yaml`'s default for real runs stays as it is.
-- At landing, the DEFERRED entry moves to Done with the landing commit.

-  The business file could then map a credential to that instance
-  (business.mjs:157). Nobody has traced whether a mapped credential
-  reaches the run's environment. The decision paths stay closed (M6),
-  but a creative role with `web` holding a live token is a wider channel
-  than design 4 means. The fix: refuse any `credentials` in

-  isn't `mosaic-stack` nothing orders the two. The bus can start before
-  the boot stop runs, and after a boot-time drift role sessions can use
-  bwrap until it does. The fix: `After=mosaic-hostcheck.service` in
-  `packages/cli/systemd/mosaic-bus.service.in`, which orders every
-  instance and does nothing where the unit isn't installed. It goes in
-  before the first install whose business id isn't `mosaic-stack`.

-- **The run sheet writes the apt hook before the first `--check`.**

-  usage line is `activate ID BUSINESS` (`:47`), so pasting either command
-  as printed gives a usage error, not the first step. It fails safe,

-  (set at `:2138`) to both commands, and the business (`acme`)
-  to the three expected strings in `stack-release.test.mjs`
-  (`:1538`, `:1689`, `:1691`). For a later row that edits

-- **Gate runs mount the host's pi auth file.** `compose.yaml:43` mounts
-  `${PI_AUTH_FILE:-/home/jwoltje/.pi/agent/auth.json}` read-only into
-  the agent container. No suite sets `PI_AUTH_FILE`, so the
-  `test-task.sh` cases that call `scripts/run-task.sh`, and
-  `test-release.sh` through `release.sh` `health_check` (`:41-54`), run
-  Compose with the host file. Row 197's lane `cleanEnv`
-  (`scripts/testing/gate-lane.mjs:109`) keeps the default too: it neither
-  sets nor passes `PI_AUTH_FILE`. The mount is read-only, and the legacy
-  gate already worked this way before row 197. `test-auth.sh` uses its
-  own fixtures but calls `auth.sh`, not Compose. The fix: a fixture
-  `PI_AUTH_FILE` for the Compose-reaching cases, set by the suites or by
-  the lane's `cleanEnv`, and a test that no gate step mounts the host
-  default. It needs its own row. Webby N4 on the row 197 proof driver

-- **Lane image prep inspects a base that BuildKit never tagged.**
-  (N7 of the row 197 proof.) After the Compose build,
-  `scripts/testing/lane-image.mjs:41` (`prepareImage`) runs
-  `docker image inspect node:24-bookworm-slim` to put the base digest
-  in the receipt. BuildKit resolves the base from the registry
-  without tagging it in the local store, so on a host without the tag
-  the inspect throws "No such image" after a good build. That
-  happened in Sage's proof try 1 (2026-10-21 09:03Z, run cf48efccf083).
-  The throw fails closed: the run's terminal record is unclean, both
-  lanes quarantine, and `gate-lane.sh recover` clears them. Pulling the
-  base first fixes it, and the receipt digest then matches what the
-  build used (91acba91 both ways). The fix: before the build, inspect
-  the base and refuse with a named reason if it's missing, or pull it.
-  After the build, refuse if the base digest changed. Add a test with a
-  fake Docker that has no base tag. Kept out of row 197 r6 by Sage

-  N1: F9 runs `$ROOT$NODE` as root (`scripts/case1-accept.sh:298`)
-  before F10 checks that `--node` is the `/opt/mosaic-stack/node-<pin>`
-  path (:303-304). On a host installed as designed, `case2-unit.sh:128-133`
-  refused a non-root-owned `--node` and the args file is root's, so no
-  escalation path exists today. Run F9's parse through `AS_USER`, or
-  apply F10's path check first. N2: the header (:10) and the TOOLS.md
-  entry say root only reads, but root also runs `curl` (F2), `sudo -l`
-  (P1, P3), the jarvis probe (P9), `hostcheck.sh --check` and
-  `systemctl`. Doc-only. N3: F6's prefix match (:261) accepts a
-  `--claude` with `..` after `claude-<pin>/`. That claude runs only as
-  `mosaic`, and F10 uses equality. Darkwing has a follow-up on
-  `darkwing/row195-n1` 1e3c4767c, not yet run; it gets its own row now

Over an issued entry it is a rotate: the old value is gone from disk and memory when it returns. `service` is `gitea` or `vikunja` and the business file must already name it for the agent (`credential-unknown`). A token the bus already holds is `credential-leak`; a bad token `credential-format`; a bad date `credential-date`. Returns `{agent,verb,service,date,state}`, `verb` `issue` or `rotate`. The tester gets `tester-refused`. |
 | `credentials.revoke` | `{agent,service?,reason}`; human, or the tester (Q173). Drops the entry from memory, then unlinks a store file; a `file` or `env` reference keeps its file and becomes `store`, so a restart loads nothing. Without `service`, every kind the agent has. Returns `{agent,verb,services:[{service,state}]}`. |

-| `hosts.check` | `{host}`; same callers. Runs the host's `list <user>` as `mosaic-installer` with the installer key and the pinned host keys, then sets `state` `ready` and `checkedAt` and writes `grant.host.checked`. A nonzero exit is `host-failed`, a record that changed during the run `host-changed`, a record with no installer key `host-not-enrolled`. |
-| `hosts.remove` | `{host}`; the human or the tester. Deletes the record, writes `grant.host.removed` and removes the installer key. A `host_grants` record for the host is `host-in-use`, a guarded event naming a host line left on the host `host-line-left`. |

-# packages/library
-
-Reads a writing repo by a mapping of folders to books, types, canon and playground. This is Case 2
-row C2-01 (`docs/plans/2026-10-20_case2-rows.md`), built from design sections 1.1 to 1.3 and 7.4 in
-`agents/gosalyn/work/case2/DESIGN.md` on `gosalyn/case2-design`.
-It is pure code with no state. Business file loading (C2-04), sync (C2-03a), the index (C2-05a) and the
-guard (C2-06) build on it.
-
-## Mapping
-
-`checkMapping(entry, where, { fail })` checks a `kind: "library"` project entry and returns a
-deep-frozen copy. `where` names the entry in messages. `fail(code, message)` defaults to throwing a
-`LibraryError`. C2-04 passes its own so a business file refusal carries the file name.
-
-```json
-{
-  "kind": "library",
-  "remote": "https://git.example.invalid/her/books.git",
-  "branch": "main",
-  "vaultPrefix": "books",
-  "types": { "Characters": "character", "Places": "place", "Research": "research" },
-  "manuscript": ["Chapters"],
-  "universes": {
-    "harbor": { "name": "Harbor", "books": ["Book One"], "playground": ["Book One/Playground/"] }
-  }
-}
-```
-
-- `remote` is https with no credentials, query or fragment. `branch` is a plain ref name.
-- `vaultPrefix` is optional, one folder name.
-- `types` maps a folder name to `character`, `place`, `research`, `tracker` or `summary`.
-  `manuscript` lists folder names and shares none with `types`.
-- A universe has `name`, `books` and `playground`. A hybrid adds `kind: "hybrid"`, two or more
-  non-hybrid `sources`, `constraints` (each one `{ "exclude": ... }` or
-  `{ "pin": { "entity", "field", "value" } }`) and `notes`.
-
-Refusals:
-
-| Code | When |
-|---|---|
-| `library-playground-outside-book` | a playground prefix is not strictly inside a book of its own universe |
-| `library-mapping-invalid` | any other shape fault: unknown key, bad remote or branch, a book folder in two universes, a book folder that holds another, a playground prefix that holds another, an unknown hybrid source |
-
-## Scope
-
-`classify(mapping, path)` decides scope from the path alone. Only paths ending in lowercase `.md` are
-mapped. A path under a playground prefix is `playground`. Any other path under a book folder is
-`canon`. Everything else is `unmapped`. The type is the first folder after the book, or after the
-playground prefix: a `types` name, `manuscript`, or `null`.
-
-## Reader
-
-`readLibrary({ repo, commit, mapping })` reads one commit, never a working tree. `repo` may be a
-clone or a bare mirror. `commit` must be a full 40-hex id that names a commit, else `library-commit`.
-Git runs through `git()` and `gitBytes()` from `packages/project/src/git.mjs`, so the same safe config,
-environment and ceiling directory apply. A failed git call refuses `library-git`.
-
-It returns `{ commit, files, problems }`, deep-frozen and sorted. Each file has its path, scope,
-universe, book, type, numbered lines, `bodyLine`, parsed `frontmatter` or `null`, `frontmatterRaw`
-and `links`. Front matter `appears_in` and `relationships` wikilinks count as links.
-
-Problems carry `{ code, path, line, message }`:
-
-| Rule | Meaning | File indexed |
-|---|---|---|
-| R1 | not a regular `100644` blob of at most 1 MiB, or not UTF-8, or holds a NUL | no |
-| R2 | path is unmapped | no |
-| R3 | front matter not fully parsed, `line` is where parsing stopped | yes, front matter kept raw |
-| R4 | link resolves to no file or to more than one | yes, link dropped |
-| R5 | canon file links into the playground | yes |
-| R6 | canon file links into another universe, a hybrid's sources excepted | yes |
-| R7 | two paths differ only in case | no, neither |
-
-The front matter parser takes scalars, quoted strings, flow lists, block lists and wikilinks. Nested
-maps, anchors, block scalars and duplicate keys stop it with R3.
-
-## Links
-
-`resolver(paths, { vaultPrefix })` tries four steps in order, each with the target as written and
-then with `.md` added:
-
-1. `root`: the path from the repo root.
-2. `vault-prefix`: the same path with `vaultPrefix/` stripped.
-3. `relative`: relative to the linking file, never above the repo root.
-4. `shortest`: a target with no `/` that matches the base name of exactly one indexed file.
-
-It resolves only against indexed files. A link to a `.canvas` file or an attachment is R4. A link into
-another repo resolves to nothing. `extractLinks` skips fenced and inline code.
-
-## renderItems
-
-`renderItems(body, { scopeOf, changed })` turns a reply body into the plain text both channels show.
-It is pure. Item kinds are `fact`, `finding`, `correction` (with `from` and `to`), `question` and
-`idea`. Each cite is a path with commit, line range and quote, or a url with a quote.
-
-```
-1. Correction: Chapter 1 says grey.
-   From: "green eyes"
-   To: "grey eyes"
-   [canon] Book One/Characters/Mara Vell.md:9 @bbbbbbb "green eyes" (changed since)
-```
-
-A body of `{ "items": [], "notice": ... }` gives `No cited answer`, `No answer` or `The turn failed`.
-Any other shape gives the fixed line `This reply could not be shown.` and none of the body's text.
-
-## Survey
-
-```sh
-mosaic library survey <repo> [--mapping <file>]
-```
-
-It reads the repo's HEAD commit and prints folder names, file counts by extension, front matter key
-sets and link-form counts. It never prints file text, front matter values, file names or link targets.
-A key that is not a short identifier prints as `(other key)`, since it could be her words. With
-`--mapping` it adds scope counts, resolver step counts and problem counts by rule.
-
-Exit codes follow `packages/project`: 0 done, 2 the repo can't be read (`library-git`,
-`library-commit`), 3 a bad mapping, 4 usage. `scripts/mosaic` sends `library survey` here. Other
-library verbs will be bus verbs.
-
-## Tests
-
-```sh
-node --test packages/library/tests/
-```
-
-Fixtures are made-up repos built per test in a temp dir. A marker string stands in for her text, and
-the survey tests check that it never appears in output.
