+# Row 195 build: `scripts/case1-accept.sh`
+
+Row 195 (#1693), the Case 1 install on 10.1.1.53. Design r7 at 5425ea2f3, approved by Duckworth
+(duckworth-0087, `agents/duckworth/work/row195/REVIEW-r7.md` at 58d930f89; Gitea 29962). Sage's go to build
+is sage-1817.
+
+## What this commit holds
+
+- `scripts/case1-accept.sh` (new, 100755): section 5's acceptance, F1-F11 and P1-P11.
+- `packages/cli/tests/case1-accept.test.mjs` (new): section 5's cases.
+- `docs/TOOLS.md`: the `case1-accept.sh` entry after the hostcheck entry.
+- This file.
+- `DESIGN.md`, doc-only fixes Sage named in sage-1817, with no new design round:
+  - Duckworth's N1. Section 1's human-id row cited `broker.mjs:245`; the check is `broker.mjs:321`.
+  - Row 226's state at :21 and :326. It said "unclaimed"; 226 is assigned to Gosalyn, briefed and not
+    started (sage-1814).
+  - :340 said I'd send the section 6 items to Gosalyn once 226 was claimed. I sent them on 2026-10-21
+    and Gosalyn acknowledged (gosalyn-0085), so the line now says that.
+
+Nothing else changes. No `case2-*.sh`, `stack-upgrade.sh`, `stack-release.sh`, `case1-hostcheck.sh` or run
+sheet edit, and nothing touches .53 (sage-1809).
+
+## Deviations from section 5, and choices it left open
+
+1. P4's mark is the single token `accepted Q182+Q183`. Section 5 lists `accepted Q182` and `accepted
+   Q183` as marks and gives P4 both. One line can carry one mark, and P4 is the only Q182 path, so the
+   count list has `accepted Q182+Q183` in place of `accepted Q182`.
+2. The test seam replaces `getent`. Under `--root`, the script reads `DIR/etc/passwd` and `DIR/etc/group`
+   with awk. Without it, the same helper calls `getent`. The groups of a user are its primary gid, then
+   each group whose member list names it, which is what `id -G` prints. So there is no fake `id`, and
+   the script never calls `id` for another user.
+3. P10 reads the port floor from `/proc/sys/net/ipv4/ip_unprivileged_port_start` rather than calling
+   `sysctl`, so the seam covers it the way hostcheck's item 7 is covered. There is no fake `sysctl`.
+4. There is no fake `bwrap`, `claude`, `node` or `hostcheck.sh` on PATH. The script runs each by the
+   absolute path the args file or the install names, so the test puts stubs at those paths under
+   `--root`, and the fake `sudo` runs the stack's user's commands from the tree.
+5. The args file must say `--profile factory` and name `--business`. Both are new refusals beyond
+   `stack-upgrade.sh`'s rules. A library file, or one for another business, would make F4 and F7
+   check the wrong thing. After `--`, `--port` and `--tester-port` must be numeric. The args file is the
+   only source of the ports.
+6. F8, F9 and F11 read file metadata as root: `stat`, `-L` and `find -maxdepth 1 -name '*.json'`. None
+   opens the credential. F9 parses `managed-settings.json` with the pinned node, run by root: that node
+   and that file are both root's own, installed by ops-01.
+7. F7 reads `launch.by` from `$HOME/.config/mosaic-dev/businesses/<id>.json` as the stack's user. That
+   path is `businessFilePath(id)` under the default config, which is what the unit uses. It doesn't load
+   the copy's `business.mjs` as `stack-release.sh`'s `plugins launchby` does. The user runs the whole
+   check and prints one line, and root accepts only `ok <instance> run <run>` (sage-1653: root doesn't
+   parse the user's output beyond a fixed pattern).
+8. F5 names a process claude when its argv0's basename or its `comm` starts with `claude`. The window
+   confirms this against a real role session. If the bwrap'd claude shows another name, F5 fails closed
+   and the fix is this match, not the label check.
+9. F3 and F5 run together. `talk` goes out in the background under `timeout 330`, and the `/proc` scan
+   repeats every half second until it finds a labelled pair or `talk` exits. F3's line prints first, then
+   F4, then F5, so the output keeps id order. F3 passes on exit 0 with the `sent` line and a reply line,
+   both counted on stdout only (`cli.mjs:395` and the `formatMessage` write); talk's error goes to stderr.
+12. `--claude` must match `^/[A-Za-z0-9/._+@-]+$`. The `@` is for `node_modules/@anthropic-ai/...`;
+    `stack-upgrade.sh` doesn't check `--claude` at all.
+10. F1 requires all four uids in `/proc/<MainPID>/status` (real, effective, saved, filesystem) to be the
+    user's.
+11. Evidence text the stack's user controls (talk's last line, the precheck's last line, F6's and F10's
+    `--version`) is cut to printable ASCII, one line, 200 bytes.
+
+## Tests
+
+`packages/cli/tests/case1-accept.test.mjs`, 22 tests. Every case builds a scratch host with every F check
+passing and every P check closed or accepted, then changes one thing:
+- all pass: exit 0, ids in order, each P mark, the count lines match the check lines, and the stand-in
+  credential's value appears nowhere;
+- each F check failing alone exits 1 with only its line failing;
+- F3 on exit 0 with only the `sent` line, and its evidence taking talk's stderr;
+- F1 on a failed unit and on `User=root`; F2 on healthz failing and on another pid holding the port;
+- F5 on `unpriv_bwrap (enforce)`, `bwrap//&unpriv_bwrap (complain)`, a trailing space on either label,
+  no bwrap of the user's, and passing on `comm` alone;
+- F6 on a stub that prints nothing and on a path outside `claude-<pin>`;
+- F7 on two live PM launches, a live one for another business, and no `launch.by`;
+- F8 on 0640, on another owner and on a symlink, never printing the credential;
+- F9 on a group-writable mode, another owner and a number for the flag;
+- F11 on one `*.json` under `discord/`, and passing on an empty directory;
+- each P check's unnamed mark, with the line count each fault makes: P6 one line per member, P9 one per
+  missing item; P2, P5, P10 and P11 in more than one way;
+- every P check unnamed at once still exits 0;
+- nine bad args files refuse with exit 2 before any command runs, each with its own refusal text;
+- usage errors, and a user's run without `--root`, exit 2;
+- every in-instance call goes through `sudo -u mosaic -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin`,
+  read from the fake `sudo`'s argv, and root's other `sudo` calls are exactly `-l -U mosaic`,
+  `-l -U localadmin` and the jarvis bwrap probe;
+- the host check records `--check` and never `--enforce`.
+
+## Mutants
+
+Section 5's twelve, each one exact replacement in `scripts/case1-accept.sh`, run by
+`/mnt/storage/scratch/darkwing-195-out/mutants.py` in Sage's slot (sage-1865). All twelve were killed.
+After each one the script's bytes were restored, and the final sha256 matched (`d434f15ff638...`). The
+killers below are the tests that failed in each mutant's saved log.
+
+| # | Mutant | Killed by |
+|---|---|---|
+| 1 | F1 passes on a MainPID owned by root | each F alone |
+| 2 | F2 accepts a listener on 0.0.0.0 | each F alone |
+| 3 | F3 passes without a reply | each F alone; F3 exit 0 with no reply line |
+| 4 | F5 matches a substring | F5 labels (the trailing space) |
+| 5 | F6 skips the `--version` check | each F alone; F6 stub and path |
+| 6 | F8 skips the owner check | F8 0640, owner and symlink |
+| 7 | F11 ignores `discord/` | each F alone; F11 `*.json` |
+| 8 | P1 closes on any output | P unnamed; every P unnamed |
+| 9 | P5 maps to `closed` with jarvis in docker | P unnamed; every P unnamed; P2 and P5 names docker |
+| 10 | P9 drops the jarvis item | P unnamed; P9 per item |
+| 11 | P11 accepts any `Before=` | P unnamed; every P unnamed |
+| 12 | a P check's `unnamed` sets the exit to 1 | P unnamed; every P unnamed; P10 and P11; P2 and P5; P9 per item |
+
+Mutant 1 survived the F1 variants test (a failed unit, `User=root`), because those faults fail F1 on the
+unit's state and `User=`, not on the uid line. Each F alone covers the uid line.
+
+## Pre-slot read review
+
+Since every test run is slot work, a read-only subagent traced each case through the script before the
+first slot run, executing nothing. It found four defects, all fixed in this commit:
+- The `--claude` regex had no `@`, so every run refused the args file, the real .53 one included.
+- The fake `stat` logged the args-file call, so the bad-args test's "no command ran" check would fail.
+- The P5 and P6 faults each rewrote `etc/group` from the constant, so applying both lost P5's change.
+- F3 counted stderr into its line count, so a mutant dropping the exit check survived. F3 now counts
+  stdout only, and a `sent`-only case covers the line count.
+
+## Run environment
+
+The build commit ddf7dce6c sits on base 4ced5e63d (origin/refactor when it was pushed). It was first built
+on c515273db as 4a51d392c. Row 238 then changed `docs/TOOLS.md`, so I cherry-picked the three commits onto
+4ced5e63d as `darkwing/row195-b`. `git range-diff` shows all three identical. node v26.8.1 on dragon-lin,
+every run behind my busy check and Sage's, chained with `&&`.
+
+- Step 1, sage-1829 (07:41:54Z to 07:42:05Z), TMPDIR `/tmp/dw195`:
+  `node --test packages/cli/tests/case1-accept.test.mjs`, 22 pass, 0 fail, 11.0 s.
+- Step 2, sage-1865 (08:34:27Z to 08:36:21Z), TMPDIR `/mnt/storage/scratch/tmp/r195`: the twelve mutants
+  above, all killed.
+- Step 3, the gate (08:36:21Z to 08:47:06Z), same TMPDIR, `COMPOSE_PROJECT_NAME=darkwing-r195`:
+
+| Suite | Result |
+|---|---|
+| packages/cli (`node --test tests/*.test.mjs`) | 662 pass, 0 fail, 0 skipped |
+| test-auth.sh | 15 passed, 0 failed |
+| test-conductor.sh | 17 passed, 0 failed |
+| test-config.sh | 31 passed, 0 failed |
+| test-discord.sh | 78 passed, 0 failed |
+| test-extension-package.sh | 18 passed, 0 failed |
+| test-foundation.sh | 44 passed, 0 failed |
+| test-land-work.sh | 86 passed, 0 failed |
+| test-queue.sh | 156 node pass, 0 fail; 28 passed, 0 failed |
+| test-release.sh | 14 passed, 0 failed |
+| test-task.sh | 98 passed, 0 failed |
+
+Summed: 818 node tests passed with 0 failed, and 429 selftests passed with 0 failed. The compose network
+was removed afterwards, and the sweep found no process left in the worktree, the output directory or the
+TMPDIR. This file's results are a doc-only commit on top of the build, so nothing that ran has changed.
+
+## Correction to deviation 6 (follow-up, 2026-10-21)
+
+Deviation 6 says the node F9 runs is root's own. At 37171f65b the script didn't check that. F9 ran
+`--node` as root before F10's path check, so the header's "root itself only reads" was false
+(Duckworth's N1, `agents/duckworth/work/row195/REVIEW-m1.md` at 6afcee2a5). A host installed as designed
+was safe, because `case2-unit.sh` refused a non-root-owned `--node`. Row 245 carries the fix and its
+tests: `agents/darkwing/work/queue-245/BUILD.md`.

+# Row 195 design: the Case 1 install on 10.1.1.53 (r7)
+
+Darkwing, 2026-10-21. Brief: `docs/plans/2026-10-20_hub-own-uid.md`, blob 45be7f09afc1, section "Brief: the
+Case 1 install on 10.1.1.53 (row 195)". Gitea #1693. Reviewer Duckworth, gate owner Sage. Branch
+`darkwing/row195-r7` on c515273db. r6 (b7239bb66 on `darkwing/row195`, approved duckworth-0055) is the base,
+carried unchanged as 7398b7dd7. The r6 text is in that commit and in b7239bb66.
+
+## Changes from r6
+
+Q187 (mos-1108) made install and upgrade product commands, and mos-1118 split r6 into the installer rows
+(`docs/plans/2026-10-20_installer-rows.md`). That brief says row 195 "shrinks to the factory profile's
+values and the Case 1 acceptance". So r7 is mostly a cut. What r6 designed now ships elsewhere:
+
+| r6 piece | Now | State |
+|---|---|---|
+| `stack-release.sh --units external`: `confirm`, `revert`, `gate`, `rollback --to`, external `adopt` and `status`; `stack-copy.sh check --units external` and bundle copies | row 232, I1 | landed |
+| `case1-repin.sh` (A1-A5, A2f, R1-R4) | `scripts/stack-upgrade.sh`, row 233, I3 | landed |
+| the host steps 2a, 2a', 2a'' and the window's root steps | `docs/guides/host-run-sheet.md` sections 1-10, row 233 | landed |
+| `case1-hostcheck.sh`, `case1-pins.sh`, `mosaic-hostcheck.service` (the drift stop, r6 B2) | row 240, I4 | landed c515273db |
+| the unit render, `--profile factory`, `--pm`, `--claude`, the factory serve flags, the precheck | row 230, C2-13a, I2 | landed |
+| the install as `mosaic`: bootstrap, business file, copy | row 226, C2-13b, I2, `scripts/case2-install.sh` | assigned to Gosalyn, briefed, not started |
+| `docs/guides/case1-install.md` | the host run sheet, plus section 6 of this file | |
+
+Other changes:
+
+- Claude moves under `/opt` (sage-1522, run sheet section 3). `--claude` is
+  `/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe`, root's, and root
+  installs and upgrades it. r6's `/srv/mosaic/.local/bin/claude` is gone. F6 reads the new path.
+- The args file is `/etc/mosaic-stack/dev.args` (run sheet section 7), not `case1-unit.args`. It holds
+  `--copy` too, and `stack-upgrade.sh` rewrites only that line, after confirm passes.
+- Both units are `WantedBy=multi-user.target` and start at boot (Q189, mos-1122). r6's "the Console has no
+  `[Install]`, root starts it by hand after a reboot" no longer holds.
+- The business id is stated, with the DEFERRED 240 N1 reasoning (sage-1809, sage-1813). Section 7.
+- The window can't run until row 226 lands. Sage added 226 to row 195's after list at rev 2718
+  (sage-1813). Section 6 lists what row 195 needs from 226's install.
+- The acceptance runs as root through ops-01, not as `localadmin`. `aa-status`, `sudo -l -U`,
+  `systemd-run --uid` and the hostcheck all need root. It gains four functional checks for items the run
+  sheet marks "precheck line missing" (F8-F11) and one host line (P11). Section 5.
+- The Discord row in section 2 changed. The precheck's "no Discord binding" line is C2-13b's and is
+  library-only, so for the factory it's F11 in the acceptance.
+
+What row 195 still builds: `scripts/case1-accept.sh` and its test (section 5). The rest of this file is
+inputs, the window order and the record the reviewer checks.
+
+## 0. What I checked on the host
+

+## 1. The factory profile's values
+
+Instance `dev`, row 190's default (mos-1118 choice 4). `~` is `mosaic`'s home.
+
+| Input | Value | Who gives it |
+|---|---|---|
+| user | `mosaic`, primary group `mosaic` with no other member | fixed |
+| home | `/srv/mosaic`, 0700 | fixed |
+| config dir | `/srv/mosaic/.config/mosaic-dev` | row 190 |
+| data root | `/srv/mosaic/.mosaic-dev`, marker `{"instanceVersion":1,"name":"dev"}` | row 190 |
+| business | `mosaic-stack`, file `<configDir>/businesses/mosaic-stack.json` | fixed (section 7) |
+| profile | `factory` for `case2-install.sh`, `case2-unit.sh` and `case2-precheck.sh` | fixed |
+| roles | the factory set from `roles/`, with a chief that has a harness var | the go names the set (section 2) |
+| human id | Jason's, not `tester` (`broker.mjs:321`) | the go |
+| model credential | `<configDir>/secrets/claude-session.env`, `mosaic` 0600, one line `CLAUDE_CODE_OAUTH_TOKEN=...` | Jason places it (section 3) |
+| token slot path | none | section 2 |
+| node | `/opt/mosaic-stack/node-<v>/bin/node`, `<v>` 24 or later | the go names `<v>` and its sha256 |
+| claude | `/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe`, `<pin>` 2.1.304 unless the go names a newer one | the go |
+| PM | on (`--pm`) | fixed |
+| Console | `--port 732` on 127.0.0.1, with the unit's `CAP_NET_BIND_SERVICE` | fixed |
+| tester | `--tester-port 7333` on 127.0.0.1 (P10) | fixed |
+| board | none | fixed |
+| release | a git bundle of `refs/heads/refactor` and the 40-hex commit (run sheet section 6) | the go names both and the bundle's sha256 |
+
+The args file. `/etc/mosaic-stack/dev.args`, `root:root` 0644, one argument per line (run sheet section 7):
+
+```
+--profile
+factory
+--user
+mosaic
+--home
+/srv/mosaic
+--business
+mosaic-stack
+--copy
+<40-hex commit>
+--node
+/opt/mosaic-stack/node-<v>/bin/node
+--claude
+/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe
+--pm
+--
+--port
+732
+--business
+mosaic-stack
+--tester-port
+7333
+```
+
+`case2-unit.sh` takes exactly these before `--` (`scripts/case2-unit.sh:54`), and `stack-upgrade.sh`
+refuses `args-unreadable` on anything else (`scripts/stack-upgrade.sh:126-148`). The factory profile
+refuses the preview trio, `--send` and the proof pair (`case2-unit.sh:169`). .53 has no proxy, and Jason
+reaches the Console with `ssh -L` (sage-1451 Q3). Changing a serve flag is a re-install with its own go,
+not an upgrade.
+
+Why the port is 732 (r6, mos-1101 item 5). Role sessions share the host's network namespace
+(`packages/seat/src/sandbox.mjs:67`), so while the Console is down a session could bind a port above the
+floor and answer in its place. Below 1024 only the Console unit can bind, through its capability. The
+tester port can't go below 1024 (`packages/webui/src/cli.mjs:33`), so P10 records it.
+
+PATH for `mosaic`'s steps. `sudo -u mosaic -H` resets PATH to sudo's `secure_path`, which finds
+`/usr/local/bin/node`, v22. So every `mosaic` step runs as
+`sudo -u mosaic -H env PATH=/opt/mosaic-stack/node-<v>/bin:/usr/local/bin:/usr/bin:/bin ...`, the list
+`case2-unit.sh` renders as the units' PATH. `stack-upgrade.sh` builds it from the args file's `--node`.
+
+## 2. Where Case 1 differs from Case 2
+
+| Case 2 (library) | Case 1 (factory) | Reason |
+|---|---|---|
+| business file with the library mapping | `mosaic-stack` with no `library` key. The precheck refuses a library project under `factory` (`profile-library-business`, `case2-precheck.sh:127-128`) | the factory has no books repo |
+| `bean`, `chet`, persona vars and files, specialists | the factory roles from `roles/`, with a chief that has a harness var | the go names the set. I haven't read Jason's live business file and won't. The acceptance needs only the chief (F3); a chief with no harness var answers `no-route`. The human adds roles later with `instances.set`, no new row |
+| token slot `library-gitea` | none | the factory's per-agent git identity is row 199's credential store (Megavolt, #1697). Until it lands, git work stays on dragon-lin (Q182) |
+| `bus.tester` off | on; the precheck refuses it off under `factory` (`case2-precheck.sh:135`) | the acceptance and the Q173 test system need the tester |
+| persona modes and digests, `library.sync`, `library.status` | skipped | no persona files, no library (C2-13b brief, `factory` profile) |
+| `ZAI_API_KEY` in `claude-session.env` | not checked; the file holds `CLAUDE_CODE_OAUTH_TOKEN` | no instance has provider `zai` (run sheet section 9) |
+| no Discord binding (C2-13b, library only) | none either. F11 checks that `<dataRoot>/discord/` holds no binding | the factory's connector stays on dragon-lin. Two connectors on one bot token would split its events |
+| the claude marker prompt | runs, since the chief's harness is claude-code | |
+| serve flags: preview trio, `--send`, proof pair | `--port 732`, `--business mosaic-stack`, `--tester-port 7333` | no proxy on .53 |
+| bus: no `--pm`, no `MOSAIC_CLAUDE_BIN` | `--pm`, and `Environment=MOSAIC_CLAUDE_BIN=<--claude>` | the PM dispatches the factory's work; without the path the bus finds no claude on the unit's PATH |
+| Console proof file (run sheet section 9, .54) | none | no proof pair |
+
+All of these are inputs to the landed scripts. Row 230 implemented the four factory items r6 asked for
+(serve flags, `--pm`, `--claude`, row 190's tokens), and nothing in them hardcodes a Case 1 value.
+
+## 3. Model access
+
+Q185: Case 1 uses the account the factory uses today, the Claude subscription behind dragon-lin's
+`claude-session.env`. No script copies that file and none reads its value. In the window, Jason, or the
+person he names under the Q173 secrets rule, makes a credential for .53 from that account and writes it
+to `/srv/mosaic/.config/mosaic-dev/secrets/claude-session.env` as `mosaic`, mode 0600 (run sheet
+section 9). Nobody prints it. The check is `stat -c '%U %a %F' PATH` only (F8).
+
+The bus unit reads it through `EnvironmentFile=-` (`case2-unit.sh:243`). The leading `-` means a missing
+file doesn't stop the bus, so the chief's first launch would fail instead. The window places the file
+before the units start (section 6, W9), and the precheck's claude marker prompt then proves it works
+without printing it.
+
+Quota: the factory on dragon-lin and on .53 share one subscription. Q185's "use existing" accepts that.
+The pi harness stays off on .53 until P19 #383 settles (mos-0865). The business file names claude only.
+
+## 4. Upgrade, rollback and backup on .53
+
+All three are `scripts/stack-upgrade.sh` (row 233), run as root by ops-01 from `/root/mosaic-stack` at the
+reviewed commit. Usage, exits and the step log are in `docs/TOOLS.md`, "Root's upgrade driver", and run
+sheet section 6.
+
+| Action | Command | Who | Go |
+|---|---|---|---|
+| upgrade | `stack-upgrade.sh upgrade --instance dev --bundle /srv/mosaic/incoming/<sha>.bundle --sha <sha>` after run sheet section 6's per-upgrade lines | ops-01 | Mos per run; `--migrate` also needs Jason present (decision 96) |
+| rollback | `stack-upgrade.sh rollback --instance dev --to <copy> [--restore <ACT> [--events N]]` | ops-01 | Mos per run. Mos or Sage picks `<copy>` from `stack-release.sh status mosaic-stack --units external`, read as `mosaic`. The plan refuses unless it is the previous distinct copy |
+| backup of the store | A3's `backup_store` into `<dataRoot>/backups/stack/<ACT>`, inside every upgrade | the driver | the upgrade's |
+| rehearsal | `stack-release.sh rehearse` against the log's newest backup, before anything stops, on `--rehearse-port`, default 7339, which section 0 found free | the driver | the upgrade's |
+| backup of the VM | a PBS backup of VM 1008 before the install window and before any `--migrate` | ops-01 | the window's go (Q182, Q183: agents keep PBS) |
+
+Three .53 specifics:
+
+1. The first upgrade after install needs `--no-rehearsal` in its go. The install's adopt takes no backup,
+   so the log records none, the rehearsal exits 3 (`no-backup`), and the driver goes on only with the
+   flag (`stack-upgrade.sh:323-324`). Every later upgrade refuses the flag (`rehearsal-required`).
+2. Exit 5 (`args-failed`): the new stack is live and confirmed, but `dev.args` still names the old copy.
+   ops-01 moves the file the result line names into place with `mv -f`, and nothing else (run sheet
+   section 6).
+3. Exit 2 leaves both units stopped and the activation open. ops-01 sends Mos the exit and the last
+   lines of `/var/log/mosaic-stack/upgrade-dev.log`, and Jason or Mos settles it with `confirm` or `revert`
+   as on dragon-lin. A unit that doesn't stop within `--timeout` ends here on purpose (A2f's
+   `stale-start`, duckworth-0055 N1, now in run sheet section 6).
+
+The store backup doesn't hold the config dir or the credential. PBS backups of VM 1008 hold the whole disk,
+the credential included (P4). A restore swaps only the store and leaves `claude-session.env` in place.
+
+Re-install, for a serve flag or role change, is not an upgrade. It needs its own go and runs: stop the
+Console, then the bus; rewrite `dev.args` with the same `--copy`; `case2-unit.sh` with it; both units start
+again from the render. Row 230 N1 (webby-0046) holds here: a re-render with the units running leaves each on
+its old copy, so ops-01 stops both first. `stack-upgrade.sh` already stops both before it renders.
+
+## 5. Acceptance: `scripts/case1-accept.sh`
+
+New in this row. ops-01 runs it as root on .53, from `/root/mosaic-stack`:
+
+```
+case1-accept.sh --business mosaic-stack --args /etc/mosaic-stack/dev.args --claude-pin <pin> --node-pin <v>
+```
+
+It reads the user, home, node, claude and ports from the args file and refuses (exit 2) when that file
+fails `stack-upgrade.sh`'s rules. Every check inside the instance runs as
+`sudo -u mosaic -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin`. It changes nothing on the host
+except what F3's message writes to the store. It prints one line per check, `<id> <path> <mark>
+<evidence>`, then a count of each mark. Marks: `closed`, `accepted Q182`, `accepted Q183`, `accepted
+mos-1096`, `accepted mos-1101`, and `unnamed`, which means "not named in Q182, Q183 or a Mos ruling".
+It exits 1 when any F check fails and 0 otherwise. A P check never changes the exit. Each `unnamed`
+line goes to Mos, who takes it to Jason (R8 N1). Duckworth reads the whole output.
+
+It prints no value from `claude-session.env` and never opens it.
+
+Functional checks. Any failure fails the row:
+
+| Id | Check | How |
+|---|---|---|
+| F1 | the units run as `mosaic` | for `[email protected]` and `mosaic-webui.service`: active, `User=mosaic`, and the uid in `/proc/<MainPID>/status` is `mosaic`'s |
+| F2 | the Console answers on 127.0.0.1:732 only | `curl -fsS http://127.0.0.1:732/healthz` succeeds, and `ss -Hltnp` shows 732 bound to 127.0.0.1 only, by the Console's MainPID. Jason reaches it with `ssh -L 7332:127.0.0.1:732 [email protected]`. A LAN listener waits for Q175 SSO (sage-1451 Q3) |
+| F3 | one tester message gets a reply | as `mosaic`: `mosaic talk chief <marker> --business mosaic-stack --tester --wait 300`. A stored reply to the marked message passes. The inbox shows decisions only, so it isn't used |
+| F4 | the precheck passes | `case2-precheck.sh --business mosaic-stack --profile factory` as `mosaic` exits 0 |
+| F5 | a role session runs under bwrap with the profile | while F3's reply is pending: a `/usr/bin/bwrap` process owned by `mosaic` has a claude child. Its `/proc/<pid>/attr/current` equals `bwrap (enforce)` and the child's equals `bwrap//&unpriv_bwrap (enforce)`, exact strings after the trailing newline is cut |
+| F6 | claude is the pin | the args file's `--claude` path sits under `/opt/mosaic-stack/claude-<pin>/`, and its `--version` as `mosaic` prints `<pin> (Claude Code)` |
+| F7 | the PM run is live | `launches list --json` as `mosaic` has exactly one live entry for the PM's instance (`launch.by`), the check `confirm` runs |
+| F8 | the credential's file | `stat -c '%U %a %F'` on `claude-session.env` reads `mosaic 600 regular file`, and it isn't a symlink. Run sheet section 9 marks this "precheck line missing" |
+| F9 | the autoupdater is off | `/etc/claude-code/managed-settings.json` is `root:root` 0644 and its `env.DISABLE_AUTOUPDATER` is `"1"`. Run sheet section 3 marks this "precheck line missing" |
+| F10 | node is the pin | the args file's `--node` is `/opt/mosaic-stack/node-<v>/bin/node` with `<v>` the `--node-pin`, and its `--version` prints `<v>`. Run sheet section 2 marks this "precheck line missing" |
+| 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.
+
+| # | Step | Runs as | Source |
+|---|---|---|---|
+| W0 | re-read section 0's items; stop on any change and report it | `localadmin`, read only | section 0 |
+| W1 | PBS backup of VM 1008 | ops-01 on pve | section 4 |
+| W2 | the stack's user and home | root | run sheet 1 |
+| W3 | node under `/opt` | root | run sheet 2 |
+| W4 | claude under `/opt`, managed settings | root | run sheet 3 |
+| W5 | bubblewrap, the profile, the statoverride, the no-new-privs test, the drift stop; `hostcheck.sh --check` exits 0 with item 7 at 1023 | root | run sheet 4 |
+| W6 | the port floor (read) | root | run sheet 5 |
+| W7 | the bundle, root's checkout at `<sha>`, `mosaic`'s clone | root, then `sudo -u mosaic -H` | run sheet 6 |
+| W8 | `case2-install.sh --profile factory` with section 1's inputs: bootstrap, the business file, roles, human id, the copy | `sudo -u mosaic -H env PATH=...` | row 226 |
+| W9 | place `claude-session.env` | Jason, or who he names | run sheet 9, section 3 |
+| W10 | write `dev.args` (section 1); `case2-unit.sh` from it, which enables both units and starts the bus, then the Console | root | run sheet 7, 10 |
+| W11 | `case2-precheck.sh --business mosaic-stack --profile factory` exits 0; `hostcheck.sh --check` exits 0 with item 7 at 732 | `mosaic`; root | row 230, 240 |
+| W12 | `stack-release.sh adopt mosaic-stack --units external`, unless row 226's install does it | `sudo -u mosaic -H` | row 232 |
+| W13 | `case1-accept.sh` (section 5); the output to Duckworth, then Mos confirms | root | this row |
+| W14 | STATE report to Mos | ops-01 | brief |
+
+Install rollback, any step before W13 passes. Stop and disable both units, remove their files and
+`dev.args`, then the run sheet's rollbacks for sections 4, 3 and 2 in that order. Removing the user and
+home (`userdel -r mosaic`) needs its own Mos go, since it deletes the home. W1's backup covers the rest.
+
+What row 195 needs from row 226. Row 226 is assigned to Gosalyn, briefed and not started, so I'm listing what the window
+needs from its design, not designing it:
+
+1. `--profile factory` writes the business file with `bus.tester` on and no `library` key, and the roles
+   the go names.
+2. It writes no token slot and no persona files (its brief says so).
+3. It runs before the unit render, since the copy must exist for `case2-unit.sh --copy`, and it starts no
+   unit.
+4. Who writes `dev.args`. The C2-13b brief says the install doesn't write unit files, and the run sheet
+   says "I2's install writes it". `mosaic` can't write `/etc/mosaic-stack`. So either root's part of I2
+   writes it, or ops-01 writes it from section 1 at W10. Either works for row 195. The file's content is
+   fixed above.
+5. Whether it runs `adopt`. If it doesn't, W12 does.
+
+I sent these to Gosalyn on 2026-10-21 (gosalyn-0085 acknowledged), and the run sheet takes whichever answer 226 gives.
+
+## 7. The business id
+
+.53's business id is `mosaic-stack` (sage-1813). It appears in:
+- the args file, twice;
+- the bus unit `[email protected]`;
+- the business file name;
+- `case1-accept.sh --business`.
+
+The landed boot unit `packages/cli/systemd/mosaic-hostcheck.service` has
+`[email protected]`. So at boot the drift stop runs before .53's bus, and DEFERRED 240
+N1 (da3051ccc: `After=mosaic-hostcheck.service` in `mosaic-bus.service.in`) doesn't bind this row.
+
+If a go ever names another id for .53, the window stops before W8, and the N1 fix lands first as its own
+reviewed row. P11 is the check on the host. It reads `unnamed` when the boot unit's `Before=` doesn't
+name the installed bus.
+
+DEFERRED 240 N2 (the apt hook goes in before the first `--check`) is a run sheet order note. This row
+doesn't edit the run sheet, so it stays deferred.
+
+## 8. Rulings this design rests on
+
+- sage-1451: Q1 system units; Q3 the Console on 127.0.0.1 with `ssh -L`; Q4 a rebase goes to a new branch
+  name (#426(a), mos-1086).
+- mos-1091, mos-1096, mos-1098, mos-1101: the bwrap path, its profile and P9; the port squat and P10; .53
+  runs the PM. Their r6 sections stand, and rows 232, 233, 240 and 230 implemented them.
+- mos-1108 (Q187) and mos-1118: the installer rows and the scope cut. mos-1122 (Q189): both units start at
+  boot.
+- sage-1522: claude under `/opt`, root-owned.
+- sage-1809: no step on .53, root steps named and left to ops-01, the business id stated.
+- sage-1813: 226 in the after list (rev 2718); the id is `mosaic-stack` and 240 N1 doesn't apply.
+- Q185: the factory's model account. Q173: credentials placed by Jason or his named person.
+
+## 9. Manifest (planned)
+

+# 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`).

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

+`/mnt/storage/scratch/gizmo-235-out/mutants.py` holds each mutant as anchored edits. `--check` applies
+them in memory and runs no test. All 39 anchors match once. Each mutant runs its named test files.

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

+# Row 249 build notes (Gizmoduck)
+
+Gitea #1751, Vikunja P19 445 under #436. Brief: docs/plans/2026-10-20_host-credentials.md, section
+"Machine grant row b follow-up: the undo can't prove the remote add has ended" (6de1ebc62). Reviewer
+Duckworth, gate owner Sage. Branch gizmoduck/row249-on-8a04, on row 248's landing 8a04f4aa4 (sage-2012).
+No file under packages/bus/src changed between 6d5545d44 and 8a04f4aa4, so the brief's src line numbers
+hold on the base. Line numbers below are on this branch.
+
+## Correction to the brief
+
+The brief, copying gizmoduck-0139, puts the sweep's host-unknown refusal at broker.mjs:1350. On
+6d5545d44 it is :1349. On this branch it is :1354.
+
+## The change
+
+`#runHostGrant` in packages/bus/src/broker.mjs:
+
+- :943 adds `installed = false` next to `installing`.
+- :956 sets `installed = true` on the line after `await this.#hostGrant.install(...)`, before the
+  `stop()` that follows it. An abort that lands after install returned still ends revoked, with no hint,
+  because install returning means every request it sent has exited.
+- :1025, in the catch, inside `if (installing)` and after the remove: `if (!installed) extra =
+  { hostLineLeft: tag };`. The remove still runs first and its result doesn't matter. A remove that
+  throws sets the same hint as before (:1021).
+
+The rule keys on install not returning, not on `signal.aborted`. That covers an abort (host-run.mjs:136,
+SIGKILL to the local group), a timeout (host-run.mjs:131-134, SIGTERM, then SIGKILL after `graceMs`) and
+a dropped connection, which fails the request with no signal at all. `#hostGrantFailed` (:845) already
+adds "A line tagged X may be left on the host. Run: mosaic hosts sweep <host>" when `hostLineLeft` is
+set (:852), so the message needed no change.
+
+False hints. install is one call that runs `list`, maybe `remove`, then `add` (host-grant.mjs:329-333).
+Any failure inside it now records the hint, including a `list` that exits 1 before any add was sent, and
+an abort that lands before the first ssh starts (the G23 X5 case at "a revoke right after the spend").
+The brief accepts this for an add that exits nonzero. The other cases are the same kind: the line isn't
+on the host, and a sweep that doesn't list the tag drops the hint (G24, "a left tag no longer on the
+host", broker.mjs:1358). Narrowing it would need install to report which request was in flight, which is
+a change to host-grant.mjs's API that the brief doesn't ask for.
+
+## Row a's enroll
+
+The race can't happen there, because enrollment sends nothing to the host. `#runEnrollment`
+(broker.mjs:772-842) writes the record, calls `this.#hostGrant.enroll(business, host)` (:800) and
+commits the fingerprint. `enroll` (host-grant.mjs:247-286) runs ssh-keygen locally and writes the
+private half to its file. It opens no ssh session. The installer line goes on the host by hand: the
+notice tells ops-01 to write it, then to run `mosaic hosts check`. The undo at :835 is `unenroll`, which
+deletes the local key file. There is no remote add to outlive a kill, and no remote undo to race with.
+
+## Tests
+
+packages/bus/tests/grant-executor.test.mjs:
+
+- `lateAdd` (:451) is the shared tail. After the grant ends it asserts the code, `hostLineLeft` on
+  grant.failed, the sweep line in the notice, and that the undo's remove was the last request. Then it
+  writes `release`, so the held add writes its line and exits 0, and waits for the line in `granted`. It
+  checks there's no record, `hosts.status` lists the tag in `hostLineLeft`, `hosts.remove` refuses
+  host-line-left, `hosts.sweep` returns `removed: [tag]` and the line is gone, then `hosts.remove`
+  succeeds.
+- :468, the abort case. `hold-add`, the human approves, the add holds, `abortClaim` aborts the
+  executor's claim. Ends revoked.
+- :480, the timeout case. A 30 s wait is too long for the file, and making the timeout an option would
+  add a src seam, so the test wraps `install` through `opts.wrap` instead. The wrapper passes install its
+  own AbortController signal, waits for `holding`, aborts it, which SIGKILLs the local ssh group as the
+  timer does, then throws as a timed-out request does. The executor's signal isn't aborted, so it ends
+  host-failed. Nothing under src changes for it.
+- G8 (:283) changes. fail-list and fail-add now carry `hostLineLeft` and the sweep line. noop-add fails at
+  verify, after install returned, so it keeps no hint and the old message.
+- The comment at :436 (:432 at 6d5545d44) now says `skip` makes the held add exit without writing and that a
+  killed session's add can still write. G13 has no such comment.
+
+Both new tests write `release`, so their held stub exits before `t.after` removes the dir. Row 248's dir
+check (:67, :72) is the backstop.
+
+## Mutant
+
+/mnt/storage/scratch/gizmo-235-out/mutants-249.py, on row 235's runner. C1 removes the :1025 line and
+runs grant-executor.test.mjs. Both new tests and G8 should fail under it. `--check` matches its anchor
+once.
+
+## Runs
+
+On Sage's grant sage-2015, at 8457af076 (7cee1a1ab plus this file), TMPDIR /mnt/storage/scratch/g249t:
+
+| Run | Window | Result |
+|---|---|---|
+| grant-executor.test.mjs whole | 13:29:01-13:29:21Z | 39 of 39 pass |
+| C1 | 13:29:21-13:29:40Z | killed: both row 249 tests and G8 fail on `hostLineLeft` undefined |
+
+After C1 the worktree was clean and broker.mjs matched HEAD. After the runs, no node, sshd or sh process had a
+cwd under the worktree or g249t, and no `fake/add` or `fake/remove` stub was running. The bus suite runs on
+Sage's gate.
+
+## Rebase onto 8a04f4aa4 (sage-2012)
+
+The first commit, 02bfd184b, sat on bc579f7a8 as gizmoduck/row249, which was never pushed. Row 248 landed
+as 8a04f4aa4, changing grant-executor.test.mjs at :54, :67 and :72. gizmoduck/row249-on-8a04 starts at
+8a04f4aa4 and cherry-picks 02bfd184b with no conflict. 248's lines stay as landed. The patch-id is the
+same on both (c33823941e61). Test line numbers moved down by one, and this file was updated for that.

+
+## Rounds
+
+- Round 1: bdf18272a on gosalyn/c2-01, base 32b54ac3b. Webby approved it in Gitea comment 29704.
+- Round 2: d3c7bbf839d9c3bf50f154b18e7e4472fbd005ed on gosalyn/c2-01-r2, rebased onto 9b5362018 after row 232 drifted three paths (sage-1714). Webby approved it at merge scope, rev 2666 against comment 29921 (webby-0052).
+- Round 3: this commit on gosalyn/c2-01-r3, one commit on the row 234 landing c771a36f4 (sage-1736, sage-1779, mos-1160). Row 234 changed scripts/mosaic, so round 3 review covers that one file.
+
+## Round 2 merge
+
+range-diff 32b54ac3b..bdf18272a against 9b5362018..d3c7bbf83 shows one change, the context line where upstream added `credentials` to the scripts/mosaic case line. Patch-id moved from 8f80dfa3 to 175f45c6 for that reason only. All three drifted hunks keep both sides:
+
+- scripts/stack-copy.sh COPY_PATHS reads `packages/queue/src packages/library/src`. Row 232's bundle, --create, --units and instance code is unchanged.
+- scripts/mosaic runs the `library survey` exec block before the case line, and the case line keeps `credentials`.
+- packages/cli/tests/stack-copy.test.mjs adds `packages/library/src/index.mjs` to the copy file list.
+
+## Round 2 singles, evidence for the 19 paths other than scripts/mosaic
+
+Run on d3c7bbf83 in Sage's slot (sage-1723) from 2026-10-21T05:00:09Z to 05:11:29Z. The HEAD and a clean tree were checked first. The counts are an awk sum over the 23 logs: 481 passed, 0 failed, 0 skipped, 0 cancelled, and every file exited rc=0.
+
+| Package | File | Pass |
+|---|---|---|
+| library | links | 6 |
+| library | mapping | 7 |
+| library | reader | 11 |
+| library | render | 11 |
+| library | survey | 4 |

+| webui | service | 31 |
+| webui | views | 3 |
+
+The file list comes from the library tests plus every test that names scripts/mosaic or stack-copy.sh, by basename and by join() path. No 64-hex pin in the tests names a merged path.
+
+## Round 3 scripts/mosaic
+
+The only path both row 234 and this row change is scripts/mosaic. Row 234 added `hosts` to the cli case line and changed nothing else in the file. Round 3 takes the landed blob cce1fdee4 and adds this row's six-line `library survey` block before the case line by hand, so `hosts` stays. The mode stays 100755. The other 19 paths are byte-identical to d3c7bbf83. Against d3c7bbf83 the only difference is the `hosts` context line.
+
+Round 3 runs only the tests that read scripts/mosaic, in Sage's slot. Their counts go to Sage in T3 and onto #1713, since this file can't hold them and stay one commit. Those tests are library survey, cli app, case2-unit, credentials, hosts, host, instances, project, stack-copy, stack-release, stack-release-external, stack-upgrade, tester-reads, tester-threads and usage, queue dispatch, runs task-cli, webui pinned-copy, service and views, plus scripts/test-queue.sh. hosts.test.mjs is new with row 234.

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

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

+and 62ddc96cc. The fence export from sage-1836 Q1 was already in the commit: `personaTextFault` from

+grepping tests and scripts/test-*.sh for each non-test path's basename. The new hits name other packages'
+package.json files or write lockfiles in temp dirs, so the 18 files stand. 231 landed after that as
+29ce1e360. It touches only packages/library and the queue-231 packet, none of these 22 paths.
+
+Rerun on 48f044ccc, slot grant sage-1932, 10:18:09Z to 10:30:14Z, after a busy check. All 18 files ran
+whole, one `node --test` each, every rc 0: 419 pass, 0 fail, 0 cancelled, summed by awk. That's two more

+# Row 231 build notes, C2-01b survey escapes, list item lines and attachment embeds (#1733)
+
+Brief: docs/plans/2026-10-20_case2-rows.md "C2-01b survey escapes, list item lines and attachment embeds",
+blob 16847e94ae17. These are Webby's row 212 notes N1 to N3 (webby-0041), split out by sage-1517.
+
+## Base
+
+First built as 777f7358a on 212's first round bdf18272a. 212 landed as ee7b2f137 (sage-1886), so the
+commit was cherry-picked onto refactor fefd54e13 under the new branch gosalyn/c2-01b-r2 as 3647a5a93.
+`git patch-id --stable` is 45911915a9ee before and after. packages/library is the same in bdf18272a
+and in 212's landed round a2c72ac95, so nothing the commit touches moved under it.
+
+## What changed
+
+- N1, `packages/library/src/survey.mjs`: JSON strings escape C0 controls but leave DEL, C1 and bidi
+  controls raw. The new `quote()` escapes those too, and folder names print through it.
+- N2, `packages/library/src/reader.mjs`: front matter parsing records each block list item's line, and
+  a link in a block list carries its item's line instead of its key's.
+- N3, `links.mjs` exports `isAttachment` through `index.mjs`. A wikilink or embed whose target's last
+  segment ends in an extension other than `.md` is an attachment. The reader neither resolves nor
+  indexes it, and it raises no problem. The survey prints a count of body links to attachments.
+- `packages/library/README.md` describes all three, and the links, reader and survey tests cover them.
+
+## Outside readers
+
+`packages/cli/tests/stack-copy.test.mjs:38` checks only that `packages/library/src/index.mjs` exists, and
+`scripts/mosaic:41` execs `survey.mjs`. No test pins a hash of a library file.
+
+## Tests
+
+On 3647a5a93, slot grant sage-1889, 09:20:01Z to 09:20:14Z, after a busy check. One `node --test` per
+file, every rc 0.

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

+# Row 247 build notes, C2-20b persona import follow-up (#1749)
+
+Brief: docs/plans/2026-10-20_case2-rows.md "C2-20b persona import follow-up: printed keys, the dry run
+fence check and the mkdir race", landed in 335bb3e30. These are Webby's row 221 notes N1, N2 and N4
+(webby-0073, REVIEW-r1 a0a00630e on webby/reviews). N3 is in DEFERRED (sage-1941).
+
+## Base
+
+Branch gosalyn/c2-20b from 335bb3e30, which is row 221's landing 300766450 plus the brief.
+
+## What changed
+
+- N1, `scripts/case2-persona-import.mjs`: the per-channel prompt line prints the platform key, with its
+  fixed `platforms.` or `gateway.platforms.` prefix, and the channel key through `JSON.stringify`. A key
+  holding a newline prints as `\n` inside one quoted line. The profile name on that line is not config
+  text: `pairing` already holds it to `PROFILE_ID`.
+- N2: the dry run calls `personaTextFault` on each persona after its count line. A fault prints as
+  `profile P: persona <reason>, so C2-08's fence would refuse it`, where the reason is the fixed string
+  `personaTextFault` returns, never persona text or a line number. With any fault the run refuses, exit
+  1, and writes nothing, as stage would. The header comment no longer says a fault is counted, not
+  refused, and now says a SOUL.md over four times the fence in bytes refuses before any count, which is
+  what `soul()` already did (Webby's second point under N2).
+- N4: `privateDir` catches an EEXIST from its mkdir and refuses with `<path> was made by something else
+  between the check and mkdir`. Any other mkdir error is thrown as before, since the brief names only
+  EEXIST.
+- Tests, `packages/cli/tests/case2-persona-import.test.mjs`:
+  - The per-channel prompt test expects the quoted keys.
+  - New: a chet config.yaml with a newline in the platform key and in the channel key prints one quoted
+    line, and no output line starts with the forged text.
+  - The dry run heading test now expects the fence fault line, exit 1 and the refusal, still with
+    nothing written. Its persona has two heading lines, which the fence refuses.
+  - New: a persona of 8001 two-byte characters, 16002 bytes and under the 32000 byte cap, makes the dry
+    run print the over 8000 characters fault, write nothing and exit 1. At exactly 8000 it exits 0.
+  - New: the mkdir race refuses by name at stage, for the staging directory, and at install, for
+    `personas/<business>`. Each refused directory is left empty.
+- New fixture `packages/cli/tests/fixtures/case2-persona-import/mkdir-race.mjs`, an `--import` preload
+  like `trace.mjs`. It makes the directory named by `$PERSONA_MKDIR_RACE` just before the script's own
+  `mkdirSync` of that path, so the script meets a real EEXIST from the kernel, not a thrown stub.
+
+## Known limit of N1
+
+`JSON.stringify` escapes C0 controls, `"` and `\`, but leaves DEL, C1, U+2028, U+2029 and the bidi
+controls raw. None of those ends a line on a terminal, so the forged line N1 names can't happen. A bidi
+control could still reorder how the rest of that one line displays. The brief asks for `JSON.stringify`,
+and Sage kept it in sage-1964 because the keys come from Jason's own Hermes config. Note for Webby: row
+231's `quote()` in packages/library covers the wider set, and this row doesn't import it. If you want it,
+ask for it in review.
+
+## Mutants
+
+One per fix, plus a second for N1 so each of its two keys has its own. Each replaces one exact string
+in the script, runs the test file, then restores the script from a copy and checks its sha256.
+
+| Mutant | Fix | Change |
+|---|---|---|
+| M1 | N1 | the channel key prints raw |
+| M2 | N1 | the platform key prints raw |
+| M3 | N2 | the dry run's refusal after a fault is skipped |
+| M4 | N4 | privateDir's EEXIST branch never matches, so EEXIST is thrown raw |
+
+## Outside readers
+
+`git grep` over packages/*/tests/* and scripts/test-*.sh finds `case2-persona-import` only in its own
+test file and in two files of its fixture tree, README.md and trace.mjs, which name the test file in a
+comment. No test pins a hash of the script.
+
+## Tests
+
+Two slot runs, `busy.sh && run.sh` in /mnt/storage/scratch/gosalyn-r247, on the test file alone.
+
+Run 1, grant sage-1969, 11:47:45Z to 11:48:00Z, was red: 14 tests, 12 pass, 2 fail. The fault was in the
+script. Adding `JSON.stringify` to the per-channel line dropped the space after the comma, so it printed
+`"-1001",29 bytes`. The two per-channel tests caught it. run.sh also went on to the mutants with a red
+base, so their counts meant nothing. Sage approved both fixes in sage-1971: the space goes back, and run.sh
+now exits 3 before the mutants unless the base is rc=0 with fail 0.
+
+Run 2, grant sage-1971, 11:49:04Z to 11:49:22Z, was green: 14 tests, 14 pass, 0 fail, rc=0.
+
+| Mutant | Line | rc | Failed | Killed by |
+|---|---|---|---|---|
+| M1 | 237 | 1 | 2 | the per-channel prompt test and the newline key test |
+| M2 | 237 | 1 | 2 | the same two |
+| M3 | 238 | 1 | 2 | the dry run fence test and the dry run heading test |
+| M4 | 192 | 1 | 1 | the mkdir race test |
+
+After the run the script's sha256 was 7031d2c0dc9bd22bc748b364a35b461fc01cb98b795032a2e0ec436f3188d4e4, the
+same as the copy taken before it. The /proc scan found no process in the worktree or the scratch dir.

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

-```
-
-No gate or suite has started. Queue order from sage-1454 is 192, 201, 204,
-200, Gander, then 197. No branch deletion is authorized or attempted. Any later
-rebase uses a new branch name, and pr-merge.sh -d stays off under #426(a).
-Whichever of rows 197 and 200 lands second must rerun stack-release singly.
-Clean-candidate wrapper baselines, image preparation and paired proofs remain
-separately gated acceptance work. There is still no source commit or push.
-
-## Implementation approval and final notes, 2026-10-20T20:47Z
-
-Webby-0031 approved r2 in REVIEW-impl-r2.md at 1f404c973. Their static review
-verified every source hash/mode and patch result, and all B1/B2 cases. No queue
-review request comment exists yet; Sage owns creating it if needed.
-
-Folded all three optional notes into the same approved paths. The helper file's
-standalone fallback now shares /mnt/storage/scratch/mosaic-gate-lanes with real
-lane-a leases and leaves its stable lock files in place. Band assertions use the
-imported BANDS. Both T5 polling children fail after five seconds if their barrier
-is missed. README records the shared standalone namespace and deadlines.
-
-Fresh single-file logs review-r3-fixtures.log and review-r3-lane-a.log both pass
-8/8 with zero skips. The lane-a run has no b lock directory, and every lock was
-released. Syntax and diff checks pass. No existing test assertions or timeouts
-changed. Remaining source matches the 11/14/8-file checks from r2.
-
-Refreshed all 25 source rows in the existing frozen checkout. New digests replace
-the preceding r2 packet. gate.sh and its command are unchanged:
-
-- SOURCE.json: 3584763642506e81a532c839bdd07b111d25daa87e35dbe441d8e8c01a2c2aab
-- gate.sh: 48e06e23e45d3484755f8cd79ad5b6dfde5ef4f960081e7c455a2540e707fed1
-- BUILD.patch: 55fe390da17ab926a0593d39e79561abe52756a1b1a2c756ec57f45d90f10fde
-
-Author gate remains unstarted and queued for Sage's explicit grant. No source
-commit, suite, image build, paired proof, push or branch deletion ran.
-
-## R3 approval receipt
-
-Webby-0033 approved r3 in REVIEW-impl-r3.md at a5643f9bd. Static review verified
-the three packet hashes, all 25 source rows, and the patch result. Their review
-accepts N1-N3; no additional hang-guard test is requested. No queue review request
-comment exists yet, so Webby has not recorded a queue review.
-
-Read-only verification after receipt confirms that the approved packet hashes
-and all 25 worktree/frozen source hashes and modes still match. Source and gate
-script stay frozen. The author gate has not started and still needs Sage's grant.
-
-## Queue review round 1
-
-Sage-1476 authorized moving row 197 to in-review before the author gate.
-Created CANDIDATE.sha256 from the same 25 reviewed SOURCE.json rows. Its digest
-is 6318f0d0bba9ee90ccaa3503cac8c2e04c6397f2ef6c3564f687fbc2092989e3.
-Ran the queue move from the canonical checkout with op herb-197-review-r3.
-The move succeeded at revision 2395, opening round 1 on #1695. The request post
-failed before send because MOSAIC_GITEA_CREDENTIAL_FILE is not set; revision 2396
-records the failed outcome. Exit code 1 describes the failed post, not a failed
-row transition. Read-back confirms state in-review and the correct candidate.
-Sage will post as jarvis and give Webby the request comment number. No credential
-lookup, alternate post or retry was attempted here.
-
-SOURCE.json, BUILD.patch, gate.sh and all 25 frozen source rows remain unchanged.
-Latest slot order is row 190 r2, 201, 204, 200, Gander, then Herb. No gate starts
-before Sage sends an explicit grant ID.
-
-## Follow-on assignment
-
-Sage-1503 assigns row 215, Case 2 C2-04, to Herb after row 197 (queue rev 2455,
-Gosalyn design r11). Read docs/plans/2026-10-20_case2-rows.md, C2-04 section,
-at 5b8def2f1 when starting that row. Its required base is origin/refactor
-305857c8f. This assignment does not replace row 197 or authorize its gate.
-Keep row 197's approved source frozen while awaiting Sage's grant. Start row
-215 only after row 197, using a new branch name under the existing fleet rule.
-
-## Round 2 merge preparation on row 233
-
-Sage-1757 replaces history replay with one candidate commit on 57f59e0c3.
-The attempted history replay on herb/row197-r2-233 had already finished when
-that instruction arrived. Its only conflict was the append-only BUILD-LOG tail.
-That branch remains for history; none of its replayed commits is in this round.
-The current branch is herb/row197-r3-233, directly from
-57f59e0c399ce29b1bb85ca6af686fdc10eb195d.
-
-Stash correction: shared refs/stash was used incorrectly. The exact entry
-2767b88549dfd8c7e810908b5416876fa50cb571 is now kept on
-herb/row197-r3-wip. After verifying stash@{0} still named it, only that entry was
-dropped. The two other entries remain. No further stash creation, force push,
-branch deletion or refs/stash mutation is planned. A separate working-copy
-backup is /mnt/storage/scratch/herb197-merge-W4oiLg.
-
-Sage-1760 requires preserving every landed hunk on every changed manifest path.
-Checked each of the 25 r1 paths with git diff aa1bd209e 57f59e0c3 -- PATH.
-Exactly three changed upstream. Their r2 diff against 57f59e0c3 is captured in
-r2-merge-only.patch:
-
-| Merged path | Only row 197 changes against landed base | Landed content retained |
-| --- | --- | --- |
-| packages/cli/tests/stack-release.test.mjs | leasePort and laneAfter imports; freePort now calls the lease helper | All landed tests, including row 233's tests after R15 and BACKUP_STORE checks |
-| packages/webui/tests/service.test.mjs | leasePort and laneAfter imports; closedPort now calls the lease helper | SEND_REFUSAL permits --sso; default unit rendering removes the @CONFIG_ENV@ line |
-| scripts/test-discord.sh | fixture PI_CODING_AGENT_DIR setup; optional two-worker nested Node cap | Row 190's absent scratch MOSAIC_CONFIG selection and caller-config restoration |
-
-The other 22 paths equal the r1 reviewed source bytes and modes. r2-MERGE.json
-lists every path, its r1/r2 digest, mode, upstream-change flag and equality result.
-Source copies came from the hash-verified r1 frozen checkout. Original r1 digest:
-6318f0d0bba9ee90ccaa3503cac8c2e04c6397f2ef6c3564f687fbc2092989e3.
-No existing assertion or timeout line differs from the landed base. Static
-checks only: 20 module syntax checks, four shell syntax checks and git diff check
-pass. BUILD-LOG.md equals 57f59e0c3 byte for byte and is outside this commit.
-
-Sage explicitly requested the local candidate SHA before granting tests. This
-commit is an untested preparation checkpoint, not gate evidence. No tests or
-push are authorized yet. r2-TEST-FILES.txt lists the requested grant scope:
-16 Node test files singly and scripts/test-discord.sh, test-foundation.sh and
-test-queue.sh. The four stack-release consumers are stack-release.test.mjs,
-stack-release-external.test.mjs, stack-upgrade.test.mjs and stack-instances.test.mjs.
-The shared stack-release-fixture.mjs is exercised by its importing test files,
-not run as a standalone test. This covers all 13 touched Node test files plus
-three additional stack-release consumers and all three touched shell suites.
-
-Current slot order from sage-1760: Gizmoduck, Launchpad, Darkwing, then Herb,
-around 06:30Z. Wait for an explicit grant. After granted checks and authorized
-push, build the new candidate manifest from that pushed tip and open the
-merge-scoped round 2. Old SOURCE.json, CANDIDATE.sha256 and gate.sh remain r1
-historical artifacts and are not a clear to run the merged candidate.
-
-## Round 2 rebuilt on row 234
-
-Sage-1776 names landing c771a36f4bd0b6c359282425c668996a90072f93.
-Built a new branch, herb/row197-r4-234, directly from that landing. No history
-replay, stash, force push, branch deletion, test run or push is involved.
-The prior candidate a3b7cbde8 remains untested and is not the queued candidate.
-
-Checked git diff --name-only 57f59e0c3 c771a36f4 against all 25 source paths.
-Only packages/cli/tests/stack-release.test.mjs overlaps; the other 24 do not.
-The full comparison is in r2-on234-OVERLAP.txt. The stack-release file starts
-from the landing and keeps both T46 untimed entries, host_grants and hosts.
-Its only changes against the landing are the leasePort and laneAfter imports
-and freePort's call to the lease helper. r2-on234-merge-only.patch records those
-hunks. Existing assertions and timeouts match the landing exactly.
-
-Every other source path equals a3b7cbde8 byte for byte and retains its mode.
-This includes the previously merged service and test-discord files, preserving
-all landed --sso, CONFIG_ENV and scratch-config handling. The earlier evidence
-r2-MERGE.json still records those three pre-234 merge cases. The new
-r2-on234-MERGE.json records each current digest, prior digest, mode and equality
-result. BUILD-LOG.md equals the new landing byte for byte and is excluded.
-
-Static check of the changed Node file and the candidate diff pass. No tests
-were run. The scope stays r2-TEST-FILES.txt: 16 Node files singly plus the three
-shell suites. No manifest or queue round is rebuilt until granted checks and
-authorized push. Old SOURCE.json, CANDIDATE.sha256 and gate.sh remain historical
-r1 evidence. The test slot follows Darkwing 240 and needs Sage's explicit grant.

+# Row 213 (C2-08) build: creative roles, persona file and block, M1, M2, M6, M10, prompt by file
+
+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.
+Reviewer Webby, gate owner Sage. Base: `base.txt` (088087ac9). Manifest: `candidate-manifest.sha256`.
+D1 and D2 approved as deviations in sage-1492.
+
+## 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.

+## SETUP-SHEET.md
+
+| Claim | Source |
+|---|---|
+| She keeps writing in Obsidian, obsidian-git pushes to git.mosaicstack.dev, nothing changes on her machine, nothing commits to her repo | D:939-940 (7.1) |
+| Agents read what she pushed; a push reaches them in about a minute | D:1006-1007 (7.5); D:972-973 (60-second sync timer) |
+| Agents read `.md` notes inside book folders only | D:457-461 (1.2); `packages/library/src/scope.mjs:9-19` |
+| Not read: top-level notes, `.canvas`, `.base`, attachments, anything outside a book folder | D:461 |
+| Other repos under `~/src` are not read | D:489 (1.3), D:494-497 (N4) |
+| Agents can't write to her repo: canon, playground, anything | D:389 (D3); D:1008 |
+| Folder roles live in the `projects` entry of the business file, hand-edited, agents can't change it | D:409-429, D:443-451 (1.1, M9) |
+| Jason asks her to confirm the mapping first | D:431; D:1324-1328 (10 step 7) |
+| A folder named in `playground` is her playground | Brief:22; D:434 |
+| Each playground prefix sits inside one book folder | D:434-436; `packages/library/src/mapping.mjs:77-80` |
+| One per book, e.g. `<book>/playground/`; until then everything mapped is canon | D:438-439 |
+| Agents search canon unless they ask for the playground | D:463 |
+| Playground may back an idea or question, not a fact, finding or correction; refused before she sees it | D:858 (`playground-cited-as-canon`); D:378-382, D:835-839 (guard runs before store) |
+| Only the folder decides; a tag or property can't change scope | D:388 (D2); D:440-441; `scope.mjs:1` |
+| Graph colour group via Groups and a `path:` query, her own vault setting, changes nothing for agents | Brief:23; D:941-943. Obsidian UI steps from the task prompt, not the design |
+| Path starts with the books repo folder because the vault is `~/src` | D:939 |
+| N2: moving a note into a book folder makes it canon, agents may cite it as fact | D:944-945; D:259 |
+| Rough drafts outside the playground are canon | Inference from D:460 (scope rule) |
+| N4: Obsidian resolves short links across `~/src`, the reader sees one repo, the two can differ, the reader can't tell | D:494-497; D:262-263 |
+| A name only in another repo leads nowhere for agents | D:489 (R4); `packages/library/src/links.mjs:61-87` |
+| A full-path link resolves the same in both | D:497-498. Hub side: `links.mjs:77-78` (`vault-prefix` step) |
+| "New link format: Absolute path in vault" setting | Obsidian UI knowledge. Not in design or code. Reviewer may strike it |
+| `appears_in` and `relationships` links are read as links | D:489-490; `packages/library/src/reader.mjs:15`, `:153-162` |
+| Quoted flow list `["[[A]]", "[[B]]"]` parses | `reader.mjs:81-96` (flow), `:66-73` (quoted scalar), `:159` |
+| Block list with quoted items parses | `reader.mjs:117-122`, `:66-73` |
+| Unquoted `[[[A]], [[B]]]` is R3 | Brief:28-29; `reader.mjs:87` (bracket inside a flow list stops parsing), `:137` |
+| R3 effect: whole front matter unread, note still indexed by path, name and body, listed as a problem | D:480; `reader.mjs:103-105`, `:193`; `packages/library/README.md:69` |
+| Problems show in Mosaic's status | D:473-474; D:999-1000 (7.4 status line) |
+| A value without `[[ ]]` is a name | D:489-490; `reader.mjs:159` |
+| Bean and Chet keep names and personalities | D:660-661 (Q180) |
+| Hermes: free text and story text. Mosaic: short cited items, a prose request gets a question or idea | D:778-781 (design 4) |
+| Bean and Chet's item kinds: idea, question, finding, fact; web cites allowed | D:649 (`companion`); D:860 (`citation-unfetched`) |
+| Limits 10 items, 5 ideas of 200, others 300 | D:819 (M5) |
+| She or Jason can ask for lower limits | D:1329-1330 (10 step 8); D:831 |
+| "No cited answer" notice | D:870-871, D:996-997 |
+| One item can't mix two worlds | D:859 (`citation-cross-universe`) |
+| She talks to them in the Console; Hermes keeps running until she moves over; stopping it is her choice | D:381-382; D:1331 |
+| Five more helpers; she chooses the start set and can add one later | D:647-654; D:783-784; D:1327-1328 |

+   `--mapping` file must be the inner entry alone (`survey.mjs:114-116`). The run sheet follows the code.
+2. Design 1.3 calls `vaultPrefix` part of the mapping (D:418). The code makes it optional
+   (`mapping.mjs:48`, README:30). Without it, a full vault path link, the N4 advice, resolves to
+   nothing in the hub (`links.mjs:73-87`: `root` fails, `vault-prefix` is skipped, `shortest` refuses a
+   `/`). The setup sheet's full-path advice holds only when Jason sets `vaultPrefix` to her books repo
+   folder name.
+3. The task prompt calls the unquoted form "refused". R3 is not a refusal. It is a reported problem,
+   and the note stays indexed (D:473, D:480). The sheet says what happens instead.
+
+## Open questions
+
+1. Where `<repo>` comes from on .54. The survey reads a local repo's `HEAD` and never fetches. The bus
+   mirror needs C2-04 and C2-03a, neither landed. C2-03a moves `refs/heads/served`, not `HEAD`, so the
+   mirror's `HEAD` may name no commit and the survey would refuse with exit 2. The sync also needs a
+   checked mapping with at least one book (`mapping.mjs:59`, `:70`), and the mapping's values are
+   meant to come from this survey (D:431). Sage needs to rule: a placeholder mapping for the first
+   sync, a `HEAD` the sync sets, a `--commit` flag on the survey, or another source.
+2. The brief says Obsidian's property editor writes `appears_in: ["[[A]]", "[[B]]"]` (Brief:28-29,
+   webby-0041 N4). I didn't read webby-0041 or check Obsidian's output. Both the flow and the block
+   quoted forms parse, so the sheet shows both and says only that the editor adds the quotes.
+3. Whether `/srv/mosaic/.npm-global/bin/mosaic` exists on .54. The run sheet uses the copy's
+   `scripts/mosaic` by full path to avoid depending on a wrapper.
+
+## Sage's rulings on the open questions (2026-10-21)
+
+1. Survey source: the bus's bare mirror after the first `library.sync`, the only copy on the host
+   (design 2.1). The C2-03a brief now requires the mirror's `HEAD` to be a symbolic ref to
+   `refs/heads/served`, with a test (5c6f73ed7), so the survey reads the served commit with no ref flag.
+2. Property list forms: the sheet shows both quoted forms, since both parse. Webby checks the claim
+   that Obsidian's property editor writes the quoted form.
+3. The "New link format: Absolute path in vault" tip stays. It is an Obsidian setting, not a design
+   claim, and Webby may strike it.
+4. The run sheet calls the copy's `scripts/mosaic` by full path. That holds whether or not a wrapper
+   is on `PATH`.
+5. `vaultPrefix`: the run sheet's step 4 tells Jason to set it, because the setup sheet's full-path
+   link advice depends on it.
+
+## Round 2 (2026-10-21), from Webby's round 1 notes (webby-0075, rev 2848)
+
+- N1, by Mos's ruling mos-1165 (fix before landing): SETUP-SHEET.md now gives the 1,200 character
+  total of item text per reply (design M5, step 8). The word "Today" is gone. No code enforces these
+  caps until C2-06 lands, so my ruling is that the sheet goes to Melanie only after C2-06 lands, and
+  then only on Jason's go (#419). The wording stays as is, because by then it holds.
+- N2: SURVEY-RUN.md says tab, newline, carriage return, backspace and form feed print as `\t`, `\n`,
+  `\r`, `\b` and `\f`, and other control and bidi characters as `\uXXXX` (survey.mjs quote()).
+- N3: SURVEY-RUN.md has a refusal row for `library-commit:` (reader.mjs listTree). survey.mjs turns
+  every LibraryError into exit 2 with its message.
+- N4: SURVEY-RUN.md's new step 2 checks `command -v node` under the same sudo and PATH before the
+  survey runs.
+
+## Round 3 (2026-10-21), from Webby's round 2 note N5 (webby-0077, rev 2856)
+
+- N5: the library-commit row no longer says a moved `HEAD` causes it. The survey reads `HEAD` once,
+  and listTree raises library-commit only for an id that isn't 40 hex or an object that isn't a
+  commit (reader.mjs:29, :31). In practice that means a SHA-256 repository, so a rerun doesn't help.
+  The row now says "for example in a SHA-256 repository" and "Report to Sage".

+# Your books in Mosaic: a setup sheet
+
+This sheet is for you, Melanie. You keep writing in Obsidian the way you do now. Mosaic reads your
+books repo after obsidian-git pushes it to git.mosaicstack.dev. It changes nothing on your machine and
+commits nothing to your repo.
+
+## What the agents read
+
+The agents read your books repo as you last pushed it. A push reaches them in about a minute.
+
+They read notes, the `.md` files, inside your book folders. They don't read:
+- notes at the top of the repo, outside any book folder
+- `.canvas` and `.base` files, even inside a book folder
+- images and other attachments
+- anything in your other repos under `~/src`
+
+They can't write to your repo at all. That covers canon, the playground and everything else.
+
+Which folders are book folders, and which hold characters, places, research, your tracker or chapter
+summaries, is set in one place. It is the `projects` entry of your business file in Mosaic. Jason
+edits it by hand, and the agents can't change it. He will ask you to confirm it before the agents start.
+
+## Your playground
+
+A folder named in the `playground` list of that entry is your playground. Each playground folder sits
+inside one book folder, so one per book works well, for example `<book>/playground/`. You choose the
+names and tell Jason. Until you have one, every note in a book folder is canon.
+
+What the playground means for the agents:
+- They search canon unless they ask for the playground on purpose.
+- An agent may quote a playground note in an idea or a question. It may not use one to back a fact,
+  a finding or a correction. Mosaic refuses that reply before you see it.
+- Only the folder decides. A tag or a property can't make a note playground or canon.
+
+### Colour the playground in your graph
+
+This is a setting of your own vault. It changes nothing for the agents.
+
+1. Open the graph view and open its settings panel.
+2. Under Groups, choose New group.
+3. In the query box, type the playground's path with `path:`. Your vault is `~/src`, so the path
+   starts with your books repo folder: `path:"<books repo folder>/<book>/<playground folder>"`.
+4. Pick a colour.
+
+Add one group per playground folder.
+
+## Two things you might not expect
+
+### Moving a note into a book folder makes it canon
+
+The folder decides, so a move changes what the agents may do with a note. Once you move a note out of
+the playground into a book folder and push, it is canon. The agents may then cite it as fact. A note
+that isn't settled yet belongs in the playground. Any note in a book folder outside the playground is
+canon, rough drafts included.
+
+### A short link can point somewhere else for the agents
+
+Obsidian looks up a short link like `[[Mara]]` across your whole vault, `~/src`. The agents see only
+your books repo. Say a note called `Mara` exists in your books repo and also in another of your repos.
+Obsidian and the agents can then open different notes for the same link, and the agents can't tell.
+If the name exists only in the other repo, the link leads nowhere for the agents.
+
+A link with the full path from the top of your vault reaches the same note in both:
+
+```
+[[<books repo folder>/<book>/<characters folder>/Mara]]
+```
+
+Obsidian can write new links this way. In Settings, open Files and links and set New link format to
+Absolute path in vault.
+
+## Lists of links in properties
+
+The agents read the links in two properties, `appears_in` and `relationships`. Put quotes around each
+link in the list:
+
+```yaml
+appears_in: ["[[A]]", "[[B]]"]
+```
+
+One link per line works too:
+
+```yaml
+appears_in:
+  - "[[A]]"
+  - "[[B]]"
+```
+
+Obsidian's property editor adds the quotes for you. If you type the list by hand, don't leave them out:
+
+```yaml
+appears_in: [[[A]], [[B]]]
+```
+
+The agents' reader can't read that form. It then ignores every property of that note and lists the
+note as a problem in Mosaic's status. It still finds the note by its path, its name and its text. A
+value written without `[[ ]]` counts as a plain name, not a link.
+
+## What changes for Bean and Chet
+
+They keep their names and personalities. How they answer changes.
+
+In Hermes they answer in free text and may write story text when you ask. In Mosaic every reply is a
+short list of items. Each item is an idea, a question, a finding or a fact. Each one quotes a line
+from your repo or from a web page the agent read for you.
+
+They don't write passages. If you ask for prose, you get a question or an idea instead.
+

+# Survey run sheet for the library host
+
+This sheet is for whoever runs `mosaic library survey` on `<host>`, 10.1.1.54, under design 10 step
+7. The survey reads one commit of a git repo and prints names and counts. It never prints note text,
+property values, file names or link targets. Jason fills in the mapping for Melanie's books repo
+from its output and her answers.
+
+Out of scope: sending anything to Melanie. Design 10 step 7 makes that Jason's call.
+
+## Before you start
+
+- Jason's go for step 7. Step 4, the bot token in the `library-gitea` slot, comes first.
+- You run as `mosaic` with `sudo -u mosaic -H` from `localadmin`. `mosaic` has no login shell.
+- The stack copy from step 2 is in place at `/srv/mosaic/.local/share/mosaic-stack/copies/<id>`.
+  `<id>` is the full commit id in Jason's go. It must hold row 231, which escapes control and bidi
+  characters in folder names. In a canonical checkout, `git merge-base --is-ancestor 29ce1e360 <id>`
+  exits 0 when it does.
+- `<node dir>`, the directory that holds `node`. It is the directory of the `--node` path given to
+  `case2-unit.sh` in step 2c. `scripts/mosaic` runs `node` from `PATH`.
+- `<repo>`, an absolute path. See the next section.
+
+## The repo to survey
+
+The survey reads a local repo. It doesn't fetch. `<repo>` must:
+- be the repo's top folder, or a bare repo's own folder. A folder inside a repo refuses, because the
+  survey stops git from looking above the path's parent.
+- belong to `mosaic`. The survey gives git no global config, so a `safe.directory` entry can't
+  admit a repo another user owns.
+- have a `HEAD` that names a commit. The survey reads `HEAD` and has no flag for another ref.
+
+`<repo>` is the bus's bare mirror at `<dataRoot>/projects/<business>/<project>`, which C2-04 (row 215)
+creates and C2-03a (row 222) fetches into. It is the only copy of her repo on the host (design 2.1), and
+`mosaic` owns it. Survey it after the first `library.sync` succeeds. The mirror's `HEAD` points at
+`refs/heads/served` (C2-03a brief), so the survey reads the commit the agents are served.
+
+Don't survey anything else. A hand clone with the bot token would put the token where design 7.2 keeps
+it out, and the mirror's refs belong to the bus. If `HEAD` names no commit, stop and report to Sage.
+
+## Steps
+
+1. `ssh [email protected]`.
+2. Check which `node` runs. `PATH` ends in `/usr/bin:/bin`, so a wrong `<node dir>` would quietly run
+   another `node`:
+
+   ```sh
+   cd /
+   sudo -u mosaic -H env PATH="<node dir>:/usr/bin:/bin" sh -c 'command -v node; node --version'
+   ```
+
+   The first line must be `<node dir>/node`. If it isn't, fix `<node dir>` before going on.
+3. Run the survey without a mapping:
+
+   ```sh
+   cd /
+   sudo -u mosaic -H env PATH="<node dir>:/usr/bin:/bin" \
+     /srv/mosaic/.local/share/mosaic-stack/copies/<id>/scripts/mosaic library survey <repo>
+   echo "exit $?"
+   ```
+
+4. On exit 0, give the output to Jason. On any other exit, see "Refusals" below.
+5. When Jason has a draft mapping, run it again with `--mapping`. The file holds the library entry
+   alone, `{"kind": "library", "remote": ..., "branch": ..., ...}`, without the business file or the
+   `"projects"` wrapper around it. `remote` and `branch` are required even though the survey doesn't
+   fetch. `mosaic` must be able to read the file. Set `vaultPrefix` to her books repo's folder name
+   in her vault. Without it, a link with the full path from the top of her vault resolves to nothing,
+   and the setup sheet tells her to write links that way.
+
+   ```sh
+   sudo -u mosaic -H env PATH="<node dir>:/usr/bin:/bin" \
+     /srv/mosaic/.local/share/mosaic-stack/copies/<id>/scripts/mosaic library survey <repo> --mapping <file>
+   echo "exit $?"
+   ```
+
+The usage line is `mosaic library survey <repo> [--mapping <file>]`. `--mapping <file>` is the only
+flag, and it may appear once. `--mapping=<file>` and every other flag refuse.
+
+## What the output holds
+
+Plain text on stdout, one line per item:
+
+| Line | What it holds |
+|---|---|
+| `commit <id>` | the 40-hex commit `HEAD` names |
+| `entries <n>` | every entry in that commit's tree |
+| `folders (direct children: md canvas base other)` | then one line per folder that holds a file directly: its path as a JSON string and four counts. `(root)` is the repo's top |
+| `markdown <n> files, <n> read, ...` | `.md` files, how many were read, how many have no front matter, how many have front matter the reader can't fully parse |
+| `front matter key sets` | then `<count> [<keys>]` per set of property names. A name that isn't a short identifier prints as `(other key)` |
+| `body links plain .., label .., heading .., embed .., self .., markdown ..; attachment ..` | link forms in note bodies, and embeds of a target with an extension other than `.md` |
+| `field appears_in wikilink .., name ..` | values written as links and as plain names. A `relationships` line follows |
+
+With `--mapping` three lines follow:
+
+| Line | What it holds |
+|---|---|
+| `scopes canon .., playground .., unmapped ..; indexed ..` | tree entries per scope, and notes indexed |
+| `resolved root .., vault-prefix .., relative .., shortest .., unresolved ..` | links per resolver step. `unresolved` is the R4 count |
+| `problems R1 .., ..., R7 ..` | problems per rule |
+
+Folder paths and short property names are the only words from her repo in the output. In a folder
+name, tab, newline, carriage return, backspace and form feed print as `\t`, `\n`, `\r`, `\b` and `\f`.
+Any other control or bidi character prints as `\uXXXX`.
+
+## Refusals
+
+A refusal prints nothing on stdout and one line on stderr. The survey checks the mapping before the
+repo, so a bad mapping gives exit 3 even when the repo path is wrong too.
+
+| Exit | stderr | Cause | What to do |
+|---|---|---|---|
+| 4 | `library survey: usage: mosaic library survey <repo> [--mapping <file>]` | no repo, two repos, an unknown flag, `--mapping` without a file or twice | Fix the command |
+| 3 | `library survey: library-mapping-invalid: <file> is not a readable JSON file` | missing, unreadable by `mosaic`, or not JSON | Fix the file or its mode |
+| 3 | `library survey: library-mapping-invalid: <file> <reason>` | the entry breaks the schema. The reason names the key | Give it to Jason for the draft |
+| 3 | `library survey: library-playground-outside-book: <file> universes.<u>.playground "<prefix>" is not inside one of its books` | a playground prefix outside its universe's books | Give it to Jason for the draft |
+| 2 | `library survey: library-git: <repo> is not a directory` | wrong path | Check `<repo>` |
+| 2 | `library survey: library-git: repository has no readable HEAD commit (project-git)` | not a repo, a folder inside one, another owner, no commits, a `HEAD` with no commit, or no `git` on `PATH` | Check each. If `<repo>` is the bus mirror, stop and report to Sage |
+| 2 | `library survey: library-git: <other reason>`, such as `tree listing refused (project-git)` | git failed or ran past 100 seconds | Report to Sage |
+| 2 | `library survey: library-commit: <reason>` | `HEAD` names something the reader can't take as a commit, for example in a SHA-256 repository | Report to Sage |
+| 127 | a line ending `exec: node: not found` | `node` isn't in `<node dir>` | Fix `<node dir>` |
+| other | a Node stack trace | a fault in the survey | Stop and report the exit code to Sage |
+
+A refusal is the answer, not an obstacle. Don't run as another user, change modes on her repo or edit
+its refs to get past one.

+- N1: lines :147 and :237 print channel and platform keys from `config.yaml` as they are. A key with a
+  newline or a control character could forge an output line.
+- N2: the dry run counts but doesn't apply C2-08's 8000-char fence. A persona over the fence and under
+  32000 bytes passes the dry run and then refuses at staging.
+- N4: `privateDir` runs lstat, then mkdir. A directory made between the two gives a raw EEXIST. It still
+  fails closed, so only the error text is wrong.

+### What ships

+- N1: every printed config key goes through `JSON.stringify`.
+- N2: the dry run calls `personaTextFault` on each persona and prints the fault's name. It still prints
+  no persona text, no line and no line number.
+- N4: an EEXIST from the mkdir refuses with a named reason, not a raw EEXIST.
+
+Tests:
+- A fixture key with a newline prints as one quoted line.
+- A persona over the fence makes the dry run print the fault, write nothing and exit nonzero.

+Creative roles get no host grant (mos-1163, from Webby's N2 on row 213 r4). Since row 234, a role
+definition's credentials no longer gate host access, so the host grant writer itself refuses a grant whose
+agent is a `CREATIVE_DEFINITIONS` role (row 213), with a named reason and a test. The Case 2 hub runs
+creative agents on .54, and without this a creative role has a path to `host.run`. Duckworth's review checks
+it, and answers from the code whether a decision raised by another role can be spent by a creative one.
+
+`host.run` refuses too, at spend time, when the agent's current definition is a `CREATIVE_DEFINITIONS` role
+(sage-1908, accepted in mos-1164). That covers a grant written before the role became creative. The refusal
+leaves the grant record in place, so `hosts.revoke` still finds it. Each path, the writer refusal at raise
+and at the step 1 recheck and the spend refusal, gets its own test and its own mutant.

+
+## Machine grant row b follow-up: the held stubs end with their test
+
+The row 197 r8 D5 proof stopped on a leftover process on 2026-10-21. In
+`packages/bus/tests/grant-executor.test.mjs`, the `add` stub waits for `release` when `hold-add`
+is set. G23 ("a revoke during install") and G13 write `release`, finish, and `t.after` removes the
+test dir. The stub polls every 50 ms, so it usually misses `release` and then loops forever on a
+dir that is gone. Four runs of the file on Sage's slot left 7 stubs, every run 37/0.
+
+Build: each hold loop in that file, `hold-add` and `hold-remove`, also stops when `$D` no longer
+exists. The test file is the only change. Nothing under `src` changes.
+
+Gate: Webby approves the commit. On Sage's gate the whole file passes three times in a row with no
+stub left, checked by pgrep on the run's TMPDIR, and the bus suite is green. A mutant that drops the
+dir check from `hold-add` leaves a stub behind.

+## Machine grant row b follow-up: the undo can't prove the remote add has ended

+Mos asked this in mos-1166. Gizmoduck answered in gizmoduck-0137 and gizmoduck-0139, and Duckworth

+
+An abort during install SIGKILLs the local ssh process group (host-run.mjs:136). A timeout does the
+same (host-run.mjs:131-134). sshd gives a non-pty command no SIGHUP when the client dies, so the
+remote `add` can keep running. The undo runs `remove <user> <tag>` once (broker.mjs:1017). If the add
+writes its line after that, the remove has already exited 0 and `hostLineLeft` stays unset (:1019).
+Then hosts.status shows the host clean (:1396), reconcile skips a grant that already ended
+(:1042), and nothing prompts a sweep. hosts.remove's host-line-left check (:1362) passes, and once
+the record is gone a sweep refuses host-unknown (:1350), so no verb reaches the line. The line
+authorizes a key nobody holds, under the installer's restrict prefix. No test covers this case. G24
+seeds its failed grant with `hostLineLeft` already set.
+
+Build:
+- In `#runHostGrant`, mark install done right after `await install(...)` returns. In the catch, when
+  install started and never returned, record `hostLineLeft: tag` whatever the remove's exit was. The
+  rule keys on install not returning. It covers an abort, a timeout and a dropped connection, and
+  doesn't depend on `signal.aborted`. The message names `mosaic hosts sweep <host>`.
+- An add that exits nonzero on the host also records the hint. That hint is false but harmless,
+  since a sweep that doesn't list the tag drops it (G24, "a left tag no longer on the host").
+- Fix the comment at grant-executor.test.mjs:432, which says a killed session's add exits.
+- Row a's enroll add: check it for the same race, then fix it or record in BUILD.md why it can't
+  happen.
+- Owner Gizmoduck. Reviewer Duckworth.

+Tests: one abort case and one timeout case. Each uses a held stub add that writes after the remove
+and exits 0. Each asserts `hostLineLeft` on grant.failed and in hosts.status, that hosts.remove
+refuses host-line-left before the sweep, that the sweep removes the line, and that hosts.remove then
+succeeds. A mutant that drops the new catch branch fails a test.

+  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
+  (sage-1883). Mos asked for this record in mos-1162. (2026-10-21)
+- **Case 1 acceptance script: root parses with the node it's checking, and the header says less than root does.**
+  (Duckworth N1-N3 on the row 195 manifest, REVIEW-m1 6afcee2a5.)
+  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
+  that 195 has landed (b65014647), Duckworth reviews. (2026-10-21)
+- **Morgana's row 213 mutation set: the B3 pattern no longer matches `bundle.mjs`.**
+  (Webby N3 on row 221 round 1, REVIEW-r1 a0a00630e.) Row 221's
+  candidate changes `packages/harness/src/bundle.mjs`, and the B3
+  anchor at Morgana's 213 `mutants.py:48` stops matching on that
+  base. This matters only if someone reruns that set. Fix the anchor
+  in that tooling before any rerun, and check that a stale anchor
+  refuses instead of skipping the mutant (sage-1941). (2026-10-21)
+- **Grant executor test X5 starts a `sleep 30` that can outlive its test.**
+  (Webby N1 on row 248 r1, webby-0080; deferred by Duckworth in the row
+  249 review, REVIEW-r1 28174fe08, #1751 comment 30070.) The test at
+  `packages/bus/tests/grant-executor.test.mjs:989` (:934 before row
+  249) runs `sleep 30` on the sshd side, where an abort doesn't reach it. Fix it with a stub
+  that exits once its test dir is gone, as row 248 did for the hold
+  stubs, or with a shorter sleep. This binds the next row that touches
+  that test file. Until then, a lane cleanup that runs after this file
+  waits 30 s before it calls a lone `sleep 30` a leak. The row 197
+  lanes scan only at lane end, about 15 minutes after pkg-bus, so they
+  can't see it (mos-1169). (2026-10-21)

 | `credentials.issue` | `{agent,service,token,date}`; human only (row 199, #1697). Writes the token to `<configDir>/secrets/agents/<business>/<agent>/<service>` (0600, dirs 0700: tmp, fsync, rename), rewrites the agent's reference in the business file to `{"store":true,<rotateBy or expires>:date}`, then holds the token in memory, with no restart. Over an issued entry it is a rotate: the old value is gone from disk and memory when it returns. `service` is `gitea` or `vikunja` and the business file must already name it for the agent (`credential-unknown`). A token the bus already holds is `credential-leak`; a bad token `credential-format`; a bad date `credential-date`. Returns `{agent,verb,service,date,state}`, `verb` `issue` or `rotate`. The tester gets `tester-refused`. |
 | `credentials.revoke` | `{agent,service?,reason}`; human, or the tester (Q173). Drops the entry from memory, then unlinks a store file; a `file` or `env` reference keeps its file and becomes `store`, so a restart loads nothing. Without `service`, every kind the agent has. Returns `{agent,verb,services:[{service,state}]}`. |
 | `credentials.delete` | `{agent,reason}`; human only. `credentials.revoke` for every kind, then removes the agent's store dir; a file there other than a token is `credential-file`. While the agent or one of its threads holds a claim, `agent-running`. |
-| `hosts.status` | No args; the human, the tester or the business's chief (row 234, #1740). `[{host,address,port,user,sudo,state,hostKeys,installerFingerprint,checkedAt,hostLineLeft}]` from the `hosts` records, with host keys as fingerprints. Never a key. |

 | `hosts.check` | `{host}`; same callers. Runs the host's `list <user>` as `mosaic-installer` with the installer key and the pinned host keys, then sets `state` `ready` and `checkedAt` and writes `grant.host.checked`. A nonzero exit is `host-failed`, a record that changed during the run `host-changed`, a record with no installer key `host-not-enrolled`. |
 | `hosts.remove` | `{host}`; the human or the tester. Deletes the record, writes `grant.host.removed` and removes the installer key. A `host_grants` record for the host is `host-in-use`, a guarded event naming a host line left on the host `host-line-left`. |
+| `hosts.revoke` | `{agent,host,reason}`; the human, the business's assistant, or the tester when `bus.tester` is exactly `true` (row 235, #1741, r6 section 6). Anyone else gets `revoke-refused`. The tester check reads `bus.tester` again at the call, `tester-dev-only`. One transaction deletes the `host_grants` record and writes `grant.revoked` with `hostLine:"pending"`. With no await between, the key leaves memory and its file goes, and a `host.run` or executor in flight aborts. Then `remove <user> <tag>` runs on the host and `grant.revoke.closed` records `hostLine:"removed"` or `hostLineLeft`. A revoke with no record still runs, with `granted:false`. Returns `{agent,host,tag,granted,keyFile,hostLine or hostLineLeft}`. A restart with a pending marker runs the remove once the bus is up; `hosts.status` lists its tag under `revoking`. |
+| `hosts.sweep` | `{host}`; the human or the tester (r6 X3). Runs `list <user>` and removes each listed tag this business recorded for the host in a `grant.step` or `grant.revoked` that no live grant holds. Another business's line and an unrecorded `mosaic-` line stay. Writes `grant.host.swept {host,removed,left}`; `hostLineLeft` then counts from it. Returns `{host,removed,hostLineLeft}`. |
 
 Each of the three leaves one receipt in the organization's `changes.jsonl`: the actor and a
 `detail` of `{verb,agent,kind,date or reason}`, never a value. A change to the store alone writes

+# 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. A link in a block
+list carries its list item's line. One in a scalar or flow value carries its key's line.
+
+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.
+
+A `![[...]]` embed resolves like any link. A body embed that resolves to nothing and whose target ends
+in an extension other than `.md`, in any case, embeds an attachment, and it is never R4. An extension is
+a dot and up to 8 letters and digits, at least one a letter. Any other unresolved embed is R4, and so is
+an unresolved front matter value written as an embed (C2-01b N3, sage-1900).
+
+## 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, link-form counts and the count of body embeds whose target has an extension other than `.md`,
+which still count as embeds. That count goes by the name alone, so an embed of `Dr.Quinn.md` written
+`![[Dr.Quinn]]` counts there too. Folder names print as JSON strings, with DEL, C1 and bidi controls,
+U+061C among them, also as `\uXXXX`. 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.
