-# 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-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.

-| `docs/guides/case1-install.md` | the host run sheet, plus section 6 of this file | |
-
-Other changes:
-
-- Claude moves under `/opt` (sage-1522, run sheet section 3). `--claude` is
-  `/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe`, root's, and root
-  installs and upgrades it. r6's `/srv/mosaic/.local/bin/claude` is gone. F6 reads the new path.
-- The args file is `/etc/mosaic-stack/dev.args` (run sheet section 7), not `case1-unit.args`. It holds
-  `--copy` too, and `stack-upgrade.sh` rewrites only that line, after confirm passes.
-- Both units are `WantedBy=multi-user.target` and start at boot (Q189, mos-1122). r6's "the Console has no
-  `[Install]`, root starts it by hand after a reboot" no longer holds.
-- The business id is stated, with the DEFERRED 240 N1 reasoning (sage-1809, sage-1813). Section 7.
-- The window can't run until row 226 lands. Sage added 226 to row 195's after list at rev 2718
-  (sage-1813). Section 6 lists what row 195 needs from 226's install.
-- The acceptance runs as root through ops-01, not as `localadmin`. `aa-status`, `sudo -l -U`,
-  `systemd-run --uid` and the hostcheck all need root. It gains four functional checks for items the run
-  sheet marks "precheck line missing" (F8-F11) and one host line (P11). Section 5.
-- The Discord row in section 2 changed. The precheck's "no Discord binding" line is C2-13b's and is
-  library-only, so for the factory it's F11 in the acceptance.
-
-What row 195 still builds: `scripts/case1-accept.sh` and its test (section 5). The rest of this file is
-inputs, the window order and the record the reviewer checks.
-
-## 0. What I checked on the host
-
-Read only, as `localadmin` over ssh, 2026-10-20 between 20:40Z and 21:51Z. Nothing in r7 touched .53
-(sage-1809). The window's first step re-reads these, since they can drift in a day: unattended-upgrades
-runs daily.
-
-| Item | 10.1.1.53 on 2026-10-20 | Needed |
-|---|---|---|
-| OS | Ubuntu 24.04.5, kernel 6.8.0-124, x86_64, 12 cores, 94 GiB, 217 GiB free on `/` | fits |
-| `mosaic` user, group, `/srv/mosaic` | absent | run sheet section 1 |
-| node | `/usr/local/bin/node` v22.22.2, root-owned | 24 or later, under `/opt` (run sheet section 2) |
-| claude | not on localadmin's PATH | under `/opt` (run sheet section 3) |
-| bwrap | absent; apt candidate `bubblewrap 0.9.0-1ubuntu0.3` | run sheet section 4 |
-| user namespaces | `kernel.apparmor_restrict_unprivileged_userns = 1`, apparmor 4.0.1, no bwrap profile loaded | run sheet section 4 |
-| profiles that name bwrap | none (`grep -rlw bwrap /etc/apparmor.d` exits 1) | hostcheck item 3 |
-| `fs.protected_hardlinks` | 1 | hostcheck item 6 |
-| `net.ipv4.ip_unprivileged_port_start` | 1024 | run sheet section 5 |
-| listeners below 1024 | 22 (sshd) and 53 (the resolver); 732 is free | the Console's port |
-| ports 7330-7333 | free | 7333 is the tester port |
-| `localadmin` | NOPASSWD sudo (#423 step 1, mos-1066, mos-1077) | ops-01's root path |
-| `jarvis` | groups sudo, docker, lxd, adm | #423 step 4 removes them (P5) |
-| unattended-upgrades | on, with the security pocket, which carries bubblewrap | the drift stop (row 240) |
-| journald | `SplitMode=uid` | the PM check reads `launches list`, not the journal (row 232) |
-
-## 1. The factory profile's values
-
-Instance `dev`, row 190's default (mos-1118 choice 4). `~` is `mosaic`'s home.
-
-| Input | Value | Who gives it |
-|---|---|---|
-| user | `mosaic`, primary group `mosaic` with no other member | fixed |
-| home | `/srv/mosaic`, 0700 | fixed |
-| config dir | `/srv/mosaic/.config/mosaic-dev` | row 190 |
-| data root | `/srv/mosaic/.mosaic-dev`, marker `{"instanceVersion":1,"name":"dev"}` | row 190 |
-| business | `mosaic-stack`, file `<configDir>/businesses/mosaic-stack.json` | fixed (section 7) |
-| profile | `factory` for `case2-install.sh`, `case2-unit.sh` and `case2-precheck.sh` | fixed |
-| roles | the factory set from `roles/`, with a chief that has a harness var | the go names the set (section 2) |
-| human id | Jason's, not `tester` (`broker.mjs:321`) | the go |
-| model credential | `<configDir>/secrets/claude-session.env`, `mosaic` 0600, one line `CLAUDE_CODE_OAUTH_TOKEN=...` | Jason places it (section 3) |
-| token slot path | none | section 2 |
-| node | `/opt/mosaic-stack/node-<v>/bin/node`, `<v>` 24 or later | the go names `<v>` and its sha256 |
-| claude | `/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe`, `<pin>` 2.1.304 unless the go names a newer one | the go |
-| PM | on (`--pm`) | fixed |
-| Console | `--port 732` on 127.0.0.1, with the unit's `CAP_NET_BIND_SERVICE` | fixed |
-| tester | `--tester-port 7333` on 127.0.0.1 (P10) | fixed |
-| board | none | fixed |
-| release | a git bundle of `refs/heads/refactor` and the 40-hex commit (run sheet section 6) | the go names both and the bundle's sha256 |
-
-The args file. `/etc/mosaic-stack/dev.args`, `root:root` 0644, one argument per line (run sheet section 7):
-
-```
---profile
-factory
---user
-mosaic
---home
-/srv/mosaic
---business
-mosaic-stack
---copy
-<40-hex commit>
---node
-/opt/mosaic-stack/node-<v>/bin/node
---claude
-/opt/mosaic-stack/claude-<pin>/node_modules/@anthropic-ai/claude-code/bin/claude.exe
---pm

---port
-732
---business
-mosaic-stack
---tester-port
-7333
-```
-
-`case2-unit.sh` takes exactly these before `--` (`scripts/case2-unit.sh:54`), and `stack-upgrade.sh`
-refuses `args-unreadable` on anything else (`scripts/stack-upgrade.sh:126-148`). The factory profile
-refuses the preview trio, `--send` and the proof pair (`case2-unit.sh:169`). .53 has no proxy, and Jason
-reaches the Console with `ssh -L` (sage-1451 Q3). Changing a serve flag is a re-install with its own go,
-not an upgrade.
-
-Why the port is 732 (r6, mos-1101 item 5). Role sessions share the host's network namespace
-(`packages/seat/src/sandbox.mjs:67`), so while the Console is down a session could bind a port above the
-floor and answer in its place. Below 1024 only the Console unit can bind, through its capability. The
-tester port can't go below 1024 (`packages/webui/src/cli.mjs:33`), so P10 records it.
-
-PATH for `mosaic`'s steps. `sudo -u mosaic -H` resets PATH to sudo's `secure_path`, which finds
-`/usr/local/bin/node`, v22. So every `mosaic` step runs as
-`sudo -u mosaic -H env PATH=/opt/mosaic-stack/node-<v>/bin:/usr/local/bin:/usr/bin:/bin ...`, the list
-`case2-unit.sh` renders as the units' PATH. `stack-upgrade.sh` builds it from the args file's `--node`.
-
-## 2. Where Case 1 differs from Case 2
-
-| Case 2 (library) | Case 1 (factory) | Reason |
-|---|---|---|
-| business file with the library mapping | `mosaic-stack` with no `library` key. The precheck refuses a library project under `factory` (`profile-library-business`, `case2-precheck.sh:127-128`) | the factory has no books repo |
-| `bean`, `chet`, persona vars and files, specialists | the factory roles from `roles/`, with a chief that has a harness var | the go names the set. I haven't read Jason's live business file and won't. The acceptance needs only the chief (F3); a chief with no harness var answers `no-route`. The human adds roles later with `instances.set`, no new row |
-| token slot `library-gitea` | none | the factory's per-agent git identity is row 199's credential store (Megavolt, #1697). Until it lands, git work stays on dragon-lin (Q182) |
-| `bus.tester` off | on; the precheck refuses it off under `factory` (`case2-precheck.sh:135`) | the acceptance and the Q173 test system need the tester |
-| persona modes and digests, `library.sync`, `library.status` | skipped | no persona files, no library (C2-13b brief, `factory` profile) |
-| `ZAI_API_KEY` in `claude-session.env` | not checked; the file holds `CLAUDE_CODE_OAUTH_TOKEN` | no instance has provider `zai` (run sheet section 9) |
-| no Discord binding (C2-13b, library only) | none either. F11 checks that `<dataRoot>/discord/` holds no binding | the factory's connector stays on dragon-lin. Two connectors on one bot token would split its events |
-| the claude marker prompt | runs, since the chief's harness is claude-code | |
-| serve flags: preview trio, `--send`, proof pair | `--port 732`, `--business mosaic-stack`, `--tester-port 7333` | no proxy on .53 |
-| bus: no `--pm`, no `MOSAIC_CLAUDE_BIN` | `--pm`, and `Environment=MOSAIC_CLAUDE_BIN=<--claude>` | the PM dispatches the factory's work; without the path the bus finds no claude on the unit's PATH |
-| Console proof file (run sheet section 9, .54) | none | no proof pair |
-
-All of these are inputs to the landed scripts. Row 230 implemented the four factory items r6 asked for
-(serve flags, `--pm`, `--claude`, row 190's tokens), and nothing in them hardcodes a Case 1 value.
-
-## 3. Model access
-
-Q185: Case 1 uses the account the factory uses today, the Claude subscription behind dragon-lin's
-`claude-session.env`. No script copies that file and none reads its value. In the window, Jason, or the
-person he names under the Q173 secrets rule, makes a credential for .53 from that account and writes it
-to `/srv/mosaic/.config/mosaic-dev/secrets/claude-session.env` as `mosaic`, mode 0600 (run sheet
-section 9). Nobody prints it. The check is `stat -c '%U %a %F' PATH` only (F8).
-
-The bus unit reads it through `EnvironmentFile=-` (`case2-unit.sh:243`). The leading `-` means a missing
-file doesn't stop the bus, so the chief's first launch would fail instead. The window places the file
-before the units start (section 6, W9), and the precheck's claude marker prompt then proves it works
-without printing it.
-
-Quota: the factory on dragon-lin and on .53 share one subscription. Q185's "use existing" accepts that.
-The pi harness stays off on .53 until P19 #383 settles (mos-0865). The business file names claude only.
-
-## 4. Upgrade, rollback and backup on .53
-
-All three are `scripts/stack-upgrade.sh` (row 233), run as root by ops-01 from `/root/mosaic-stack` at the
-reviewed commit. Usage, exits and the step log are in `docs/TOOLS.md`, "Root's upgrade driver", and run
-sheet section 6.
-
-| Action | Command | Who | Go |
-|---|---|---|---|
-| upgrade | `stack-upgrade.sh upgrade --instance dev --bundle /srv/mosaic/incoming/<sha>.bundle --sha <sha>` after run sheet section 6's per-upgrade lines | ops-01 | Mos per run; `--migrate` also needs Jason present (decision 96) |
-| rollback | `stack-upgrade.sh rollback --instance dev --to <copy> [--restore <ACT> [--events N]]` | ops-01 | Mos per run. Mos or Sage picks `<copy>` from `stack-release.sh status mosaic-stack --units external`, read as `mosaic`. The plan refuses unless it is the previous distinct copy |
-| backup of the store | A3's `backup_store` into `<dataRoot>/backups/stack/<ACT>`, inside every upgrade | the driver | the upgrade's |
-| rehearsal | `stack-release.sh rehearse` against the log's newest backup, before anything stops, on `--rehearse-port`, default 7339, which section 0 found free | the driver | the upgrade's |
-| backup of the VM | a PBS backup of VM 1008 before the install window and before any `--migrate` | ops-01 | the window's go (Q182, Q183: agents keep PBS) |
-
-Three .53 specifics:
-
-1. The first upgrade after install needs `--no-rehearsal` in its go. The install's adopt takes no backup,
-   so the log records none, the rehearsal exits 3 (`no-backup`), and the driver goes on only with the
-   flag (`stack-upgrade.sh:323-324`). Every later upgrade refuses the flag (`rehearsal-required`).
-2. Exit 5 (`args-failed`): the new stack is live and confirmed, but `dev.args` still names the old copy.
-   ops-01 moves the file the result line names into place with `mv -f`, and nothing else (run sheet
-   section 6).
-3. Exit 2 leaves both units stopped and the activation open. ops-01 sends Mos the exit and the last
-   lines of `/var/log/mosaic-stack/upgrade-dev.log`, and Jason or Mos settles it with `confirm` or `revert`
-   as on dragon-lin. A unit that doesn't stop within `--timeout` ends here on purpose (A2f's
-   `stale-start`, duckworth-0055 N1, now in run sheet section 6).
-
-The store backup doesn't hold the config dir or the credential. PBS backups of VM 1008 hold the whole disk,
-the credential included (P4). A restore swaps only the store and leaves `claude-session.env` in place.
-
-Re-install, for a serve flag or role change, is not an upgrade. It needs its own go and runs: stop the
-Console, then the bus; rewrite `dev.args` with the same `--copy`; `case2-unit.sh` with it; both units start
-again from the render. Row 230 N1 (webby-0046) holds here: a re-render with the units running leaves each on
-its old copy, so ops-01 stops both first. `stack-upgrade.sh` already stops both before it renders.
-
-## 5. Acceptance: `scripts/case1-accept.sh`
-
-New in this row. ops-01 runs it as root on .53, from `/root/mosaic-stack`:
-
-```
-case1-accept.sh --business mosaic-stack --args /etc/mosaic-stack/dev.args --claude-pin <pin> --node-pin <v>
-```
-
-It reads the user, home, node, claude and ports from the args file and refuses (exit 2) when that file
-fails `stack-upgrade.sh`'s rules. Every check inside the instance runs as
-`sudo -u mosaic -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin`. It changes nothing on the host
-except what F3's message writes to the store. It prints one line per check, `<id> <path> <mark>
-<evidence>`, then a count of each mark. Marks: `closed`, `accepted Q182`, `accepted Q183`, `accepted
-mos-1096`, `accepted mos-1101`, and `unnamed`, which means "not named in Q182, Q183 or a Mos ruling".
-It exits 1 when any F check fails and 0 otherwise. A P check never changes the exit. Each `unnamed`
-line goes to Mos, who takes it to Jason (R8 N1). Duckworth reads the whole output.
-
-It prints no value from `claude-session.env` and never opens it.
-
-Functional checks. Any failure fails the row:
-
-| Id | Check | How |
-|---|---|---|
-| F1 | the units run as `mosaic` | for `[email protected]` and `mosaic-webui.service`: active, `User=mosaic`, and the uid in `/proc/<MainPID>/status` is `mosaic`'s |
-| F2 | the Console answers on 127.0.0.1:732 only | `curl -fsS http://127.0.0.1:732/healthz` succeeds, and `ss -Hltnp` shows 732 bound to 127.0.0.1 only, by the Console's MainPID. Jason reaches it with `ssh -L 7332:127.0.0.1:732 [email protected]`. A LAN listener waits for Q175 SSO (sage-1451 Q3) |
-| F3 | one tester message gets a reply | as `mosaic`: `mosaic talk chief <marker> --business mosaic-stack --tester --wait 300`. A stored reply to the marked message passes. The inbox shows decisions only, so it isn't used |
-| F4 | the precheck passes | `case2-precheck.sh --business mosaic-stack --profile factory` as `mosaic` exits 0 |
-| F5 | a role session runs under bwrap with the profile | while F3's reply is pending: a `/usr/bin/bwrap` process owned by `mosaic` has a claude child. Its `/proc/<pid>/attr/current` equals `bwrap (enforce)` and the child's equals `bwrap//&unpriv_bwrap (enforce)`, exact strings after the trailing newline is cut |
-| F6 | claude is the pin | the args file's `--claude` path sits under `/opt/mosaic-stack/claude-<pin>/`, and its `--version` as `mosaic` prints `<pin> (Claude Code)` |
-| F7 | the PM run is live | `launches list --json` as `mosaic` has exactly one live entry for the PM's instance (`launch.by`), the check `confirm` runs |
-| F8 | the credential's file | `stat -c '%U %a %F'` on `claude-session.env` reads `mosaic 600 regular file`, and it isn't a symlink. Run sheet section 9 marks this "precheck line missing" |
-| F9 | the autoupdater is off | `/etc/claude-code/managed-settings.json` is `root:root` 0644 and its `env.DISABLE_AUTOUPDATER` is `"1"`. Run sheet section 3 marks this "precheck line missing" |
-| F10 | node is the pin | the args file's `--node` is `/opt/mosaic-stack/node-<v>/bin/node` with `<v>` the `--node-pin`, and its `--version` prints `<v>`. Run sheet section 2 marks this "precheck line missing" |
-| 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)
-
-- `scripts/case1-accept.sh` (new), mode 100755.
-- `packages/cli/tests/case1-accept.test.mjs` (new). Section 5's cases and mutants.
-- `docs/TOOLS.md`: a `case1-accept.sh` entry with usage, marks and exits, beside the hostcheck entry.
-- `agents/darkwing/work/queue-195/BUILD.md` (new): run environment, the mutant results, deviations.
-- No change to `case2-*.sh`, `stack-upgrade.sh`, `stack-release.sh`, `case1-hostcheck.sh` or the run
-  sheet. Two follow-ups stay out of this row:
-  - row 230 r2 N1. The "still on copy" line reads the id from the unit file. On .53 neither the install
-    nor `stack-upgrade.sh` reaches that line, since both start from stopped units.
-  - DEFERRED 240 N2.
-- No change to `~/.mosaic-dev`, `~/.config/mosaic-dev`, dragon-lin's units or `~/.mosaic`.
-
-Gate: Duckworth approves this design, then the manifest; the cli suite and every `scripts/test-*.sh`
-green on Sage's gate; section 5's twelve mutants killed in a slot Sage grants.

-by Sage (sage-1685, rev 2631) from `f35e7e57daee` (ad6f0be7a). The later blob only appends I4; the I3 text

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

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

Test `row 240: I3 N1: a failed args move after A5 exits 5 ...` makes `/etc/mosaic-stack` read-only at confirm and checks exit 5, the step names, `args rc=1`, the result line, both units on the new copy, the old args file's bytes and the new file beside it. The step log regex takes `exit=5`. Mutant M8. |
-| N4: section 3's `npm install` has no npm on root's PATH, and the `--claude` path is unnamed while `node_modules/.bin/claude` is a symlink `case2-unit.sh:140` refuses | The install line runs with section 2's pinned node first on PATH (the postinstall runs `node` too). The `--claude` path is `node_modules/@anthropic-ai/claude-code/bin/claude.exe`, and a `--version` line catches the postinstall's 500-byte stub. |
-| N5: sections 8 and 10 lack precheck lines | Each gets "Precheck line: none" and its missing line. |
-
-Exit 5 is new rather than 2 because 2 means both units are stopped, and here both run. Exit 4 stays usage.
-
-The `claude.exe` path comes from the 2.1.304 package itself: `npm view` gives `bin.claude` as `bin/claude.exe`,
-and its `install.cjs` hardlinks the platform binary over that placeholder, or copies it across devices, then
-sets 0755. I downloaded the tarball into `/mnt/storage/scratch/tmp/r240/cc304` and read it; nothing ran. The
-run sheet says a newer pin needs the same check.
-
-## The brief, item by item
-
-| Brief line | Where |
-|---|---|
-| 247 `case1-pins.sh` holds the three pins | `scripts/case1-pins.sh`; the pins test checks the values against r6's |
-| 248-249 seven items, `--check` exits 0 or 1 | `items()` and the final dispatch; the check tests |
-| 250-251 `--enforce`: `apparmor_parser -R`, `root:root 0700`, `DRIFT`, a log line, exit 0 | `enforce()` and `stop_bwrap()`; the four enforce tests |
-| 252 `--upstream` compares the current deb to the pin | `upstream()`; the upstream test |
-| 253 the boot oneshot | `mosaic-hostcheck.service`; the boot unit test |
-| 254-255 fakes for every host tool, r6's seven case groups, seven mutants | the test file; Tests and Mutants below |
-| 257 the I3 run sheet item points here | run sheet section 4 |
-
-## Tests
-
-Fakes on PATH, each logging its argv to `$HC/calls.log`: `aa-status`, `dpkg`, `dpkg-statoverride`,
-`apparmor_parser`, `systemd-run`, `stat`, `chown`, `chmod`, `apt-get`, `dpkg-deb`. `host(t)` builds a scratch
-root (`/etc`, `/proc/sys`, `/usr/bin/bwrap`, `/var/log`) and a lib dir with a copy of the script and fixture
-pins that hold the fixture profile's sha256. Every run passes `--root`.
-
-r6's case groups (:843-856) against the tests:
-
-| r6 case | Tests |
-|---|---|
-| `--check` exits 0 with all seven, 1 with each failing alone, its line naming it | `check: exits 0 ...`, `check: exits 1 with each item failing alone ...`, plus one test per item for the item's edge cases |
-| item 3: a second file naming `bwrap` as a word, `/{usr/,}bin/bwrap` included; passes with the profile alone | `check: item 3 ...` |
-| item 4: `unpriv_bwrap (enforce)` or a trailing space fails; the argv carries `-p NoNewPrivileges=yes` and the 2a' properties | `check: item 4 ...` checks the whole argv |
-| item 7: the floor at 732 fails | `check: item 6 ...; item 7 ...` (733 passes as the control) |
-| `--enforce` exits 0 on a pass and every failure; unload, close, `DRIFT`, one log line; `DRIFT` present with every item passing still closes | `enforce: a pass ...`, `enforce: each failure ...`, `enforce: with DRIFT present ...` |
-| `--enforce` never calls `dpkg-statoverride` with `--update`, `--add` or `--remove` | `enforce: no unload ...; never writes the statoverride` (every call is `--list /usr/bin/bwrap`) |
-| a bubblewrap version other than the pin is a line, not a failure | `check: a bubblewrap version other than the install pin ...` |
-| `--upstream` against a differing deb prints the difference, exits 0 | `upstream: ...` (also: a match, a deb with no profile, a failed download) |
-| the unit: `Type=oneshot`, `After=apparmor.service`, `[email protected]`, runs `--enforce` | `boot unit: ...` |
-
-The last test also checks that the repo script reads `scripts/case1-pins.sh` beside it, that bad usage exits
-2, and that a non-root run without `--root` refuses.
-
-Singles are the two files that run a changed script: `case1-hostcheck.test.mjs` and `stack-upgrade.test.mjs`.
-Sage asked (sage-1759) whether `stack-release.test.mjs` or `stack-release-external.test.mjs`, which share
-`stack-release-fixture.mjs`, run `stack-upgrade.sh` or `case1-pins.sh`. They don't. `grep -cF` for
-`stack-upgrade`, `case1-pins`, `case1-hostcheck` and `hostcheck` gives 0 in all three files; the control
-`stack-release.sh` gives 2 in the fixture and 8 in `stack-release.test.mjs`. `scripts/stack-release.sh` names
-`stack-upgrade.sh` once, in a comment (:2061). The gate's cli suite runs both files anyway.
-
-## Mutants
-
-r6's seven (:858-860) and one for I3 N1, scripted in `~/darkwing-scratch/r240/mutants.sh` with r233's method: a checked backup,
-an exact replacement that must match once, `bash -n`, the named killer by `--test-name-pattern`, the restore
-and a sha256 check. A dry run matched all eight once each. Results below.
-
-| Mutant | Change | Killer |
-|---|---|---|
-| M1 | `--enforce` exits 1 after the stop | `enforce: each failure exits 0 ...` |
-| M2 | `[ ! -e "$DRIFT" ] \|\| had=1` becomes `true \|\| had=1` | `enforce: with DRIFT present ...` |
-| M3 | item 1's `dpkg -S` becomes `owner=""; rc=1` | `check: item 1 fails when a package owns ...` |
-| M4 | item 3's `grep -rlw bwrap` becomes `grep -rlF /usr/bin/bwrap` | `check: item 3 ...` |
-| M5 | item 4's `[ "$label" = "$LABEL" ]` becomes a substring match | `check: item 4 ...` |
-| M6 | item 4 drops `-p NoNewPrivileges=yes` | `check: item 4 ...` (argv) |
-| M7 | item 7's `-gt` becomes `-ge` | `check: item 6 ...; item 7 fails with the floor at 732 ...` |
-| M8 | `stack-upgrade.sh`'s `finish 5 args-failed` becomes `finish 1 args-failed` (I3 N1) | `row 240: I3 N1: a failed args move ...` |
-
-## Deviations
-
-- Repo name `scripts/case1-hostcheck.sh` (r6), installed as `/usr/local/lib/mosaic-stack/hostcheck.sh`, the
-  name in brief line 239 and I3's `stack-upgrade.sh` default. r6's apt hook line says `case1-hostcheck.sh`;
-  the run sheet's hook uses the installed name.
-- `stat` is a fake too. r6 lists seven fakes; a test can't make a root-owned file, so item 5's `stat` reads a
-  fixture.
-- Item 7 with no Console unit installed reads the port as 1023 and says so ("1023, because no Console unit
-  is installed"). Until I2 installs the unit the floor must be above 1023. A unit with no `--port` fails.
-- Item 4 runs under `timeout 60`. A hung `systemd-run` would otherwise hang the apt hook and the boot unit.
-
-## Decisions
-
-- Fail closed where r6 is silent:
-  - pins with no 64-hex sha fail item 1;
-  - `dpkg -S` exit 1 (no owner) passes, exit 0 fails with the owner, any other exit fails with the code;
-  - a failed `aa-status` fails item 2 and counts as loaded, so `--enforce` tries the unload.
-- `--root DIR` is the test seam (r6 :840). Root refuses it; a non-root user needs it. Both exit 2. Root runs
-  with `PATH=/usr/sbin:/usr/bin:/sbin:/bin`.
-- `DRIFT` is append-only (`<stamp> <failed line>`), and `--enforce` never removes it. The log line is written
-  only when the stop runs: `<stamp> enforce stop items=<ids or none> drift-before=<0|1> unload=<rc=N|no-file|skipped> chown=N chmod=N`.
-- `--upstream` exits 1 when the download or the unpack fails, since it then compared nothing. A deb without
-  the profile file is a difference (exit 0), per r6 :302-303.
-- The bubblewrap note reads the version from `dpkg -s bubblewrap`.
-- The run sheet's recovery steps (`chown root:mosaic`, `chmod 0750`, `apparmor_parser -r`, then `--check`
-  before root removes `DRIFT`) are mine. r6 says only that root removes `DRIFT` in a reviewed step.

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

-## Names: r6 against section 7
-
-r6's `grant.*` and `host.enroll.*` names are `body.action` values on `action.allowed` events, not event
-kinds. The `events` kind CHECK isn't rebuilt. Four r6 names move under `grant.`:
-
-| r6 | This row |
-|---|---|
-| `host.enroll.step` | `grant.host.enroll.step` |
-| `host.enrolled` | `grant.host.enrolled` |
-| `host.checked` | `grant.host.checked` |
-| `host.removed` | `grant.host.removed` |
-
-Only the consume record carries `decision`: `{operation: 'grant.host-enroll', decision}`. Every other
-guarded body names the decision `grantDecision`, so r6's `decision` field in step, enrolled and failed bodies
-is `grantDecision` here. The actor of every guarded event is `actor_role` NULL with `actor_run` 'grant',
-and `body.by` names the caller the broker checked.
-
-## Split (r6 section 12 Q-S4)
-
-Row a builds:
-
-1. **Schema 3i to 3j.** `migrations/3i-3j.sql` adds `hosts` and `host_grants` (r6 S1, primary keys
-   (business, host) and (business, agent, host)) and the guard trigger: an `action.allowed` whose
-   `body.action` or `body.operation` GLOBs `'grant.*'` aborts unless the actor is (NULL, 'grant').
-   `SCHEMA_VERSION` 3j, a migration test with a step that fails partway.
-2. **Grant event writer.** A private session-less broker writer for guarded events. `#event` doesn't change.
-   `recordEvent` refuses `reserved-event` for the guarded namespace.
-3. **The `grant` raise frame.** `decision.raise` takes `grant` only with `credential.mint`, only from the chief
-   (`grant-chief-only`), and in row a only with `method: 'host-enroll'`. Any other method refuses
-   `invalid-request` until row b adds `host`. E1's checks, the `ssh-keyscan` set compare before the raise
-   transaction, and the rendered block.
-4. **Enrollment executor.** `#consumeGrant`, the start on the human's cli yes (X1), E2 steps 1 to 4, the
-   installer key at `<configDir>/secrets/hosts/<business>/<hostId>/installer`, the failure cleanup, and the
-   start reconcile for enrollments: the `registry` step undo, and a resolved-yes unspent enrollment ending
-   `grant.failed interrupted` (X3).
-5. **`hosts.check` and `hosts.remove`** (E4), with `mosaic hosts status|check|remove`.
-6. **`tools/host/`**: `mosaic-keys`, `mosaic-keys-write`, `mosaic-keys.sudoers`, `mosaic-keys.sshd.conf` (E3).
-7. **`host.run` on the store** (X4 first and third bullets): it reads the `hosts` and `host_grants` records
-   and the Approve record check, and at start the runtime gives `Credentials` a reference per `host_grants`
-   record. The loader refuses `hosts` at the top level and in a role (S1). Row 210's tests move to store
-   fixtures.
-8. **Reader filter** (duckworth-0067 N1): every grant-evidence reader in this row (status, the start
-   reconcile, `openGrantDecisions`) filters `kind = 'action.allowed' AND actor_role IS NULL AND actor_run =
-   'grant'`, with a test that an `action.refused` look-alike and a session-written one are ignored.
-   `hosts.remove`'s `hostLineLeft` reader is one of them (duckworth-0079 M4).
-
-Row b keeps the `host` method's raise binding (R4), the grant executor (X2), the grant rows of X3, X5,
-`Credentials.register`/`claim`/`abortClaim`, revoke (section 6) and `sweep`. So row a has no way to make a
-`host_grants` record outside a test fixture, and from its landing to row b's no agent holds a host grant
-(r6 N9, the run sheet strips row 210's keys).
-
-Tests in row a (r6 section 10): G1 and G5 for the `host-enroll` raise, G6 and G10 for the enrollment
-executor, G11's enrollment cases, G14, G15, G16, G17, G18, G20, G21 (its `host-line-left` case reads an
-event fixture until row b writes `hostLineLeft`), G25, the migration test, the trigger cases, the reader
-filter test, and row 210's T-tests on store fixtures. Row b: G2 to G4, G7 to G9, G11's grant cases, G12,
-G13, G19, G22 to G24, G26 to G28.
-
-## Early check items (duckworth-0079, REVIEW-build-split.md 10672772e on `duckworth/reviews`)
-
-Moves into row a:
-- M1. G4 for the `host-enroll` block (r6:240-242): a question can't forge the block, and the 4096-character
-  limit holds with the block appended. G4 for the `host` block stays in row b.
-- M2. The tag function (r6:265-266), because E2 step 2 tags the installer line. G24's first sentence moves
-  here: names of 64 characters with `.` and `_` give distinct tags of the fixed length. The `sweep` half
-  stays in row b.
-- M3. A store-fixture test that `host.run` refuses `host-not-granted` for no record, an unresolved decision,
-  a decision resolved by an arbiter, the tester or an agent or not via cli, a consume record with operation
-  `grant.host-enroll` in place of `grant.host`, and an unspent decision (X4 first bullet, r6:593-596). A
-  restart test that a `host_grants` fixture gives `Credentials` a reference (X4 third bullet).
-
-G21's `host-line-left` case:
-- F1. The fixture goes through this row's private grant writer in the real shape: `action.allowed`, actor
-  (NULL, 'grant'), `body.action` 'grant.failed', `body.host`, `body.hostLineLeft`. No raw SQL around the
-  trigger.
-- F2. `hosts.remove` reads `body.hostLineLeft` from any guarded body, not only `grant.failed`.
-- F3. Decided: a guarded body that carries `hostLineLeft` also carries `host`. Row b adds `host` to
-  `grant.revoke.closed`, so its body is `{tag, host, hostLineLeft}` (r6:716 has `{tag, hostLineLeft}`).
-  The reader matches on `body.host`, and doesn't map tags back to hosts through `grant.step`. A direct
-  field is one equality in SQL, and a tag lookup would add a second reader that the N1 filter also has to
-  cover.
-- F4. Row b carry: "no later `sweep` cleared it" (r6:403) needs `grant.sweep`, which only row b writes. Row
-  b adds the sweep clear to `hosts.remove` with a G21 case, and its G8 or G13 shows `hosts.remove`
-  refusing after a real `hostLineLeft` write, not only after the fixture. Until then row a's check is "any
-  guarded `hostLineLeft` for this host refuses".
-
-## Mutants (r6:838-883, numbered here)
-
-Row a, killed on this row's tree:
-
-| # | Mutant |
-|---|---|
-| A1 | drop the chief check |
-| A2 | start the executor on a `credential.mint` with no `grant` |
-| A3 | start it on an arbiter resolve |
-| A3b | start it on a `cli` yes by someone other than the human (duckworth-0083 N8) |
-| A4 | start it on `no` |
-| A5 | skip the keyscan compare |
-| A6 | compare only one key |
-| A7 | write the private key into the event body |
-| A8 | drop the "not yet enrolled" check in E2 step 1 |
-| A9 | drop the `hosts` primary key |
-| A10 | skip the start check for a resolved, unspent enrollment decision |
-| A11 | `host.run` reads the business file instead of the grant record |
-| A12 | build the tag without the business |
-| A13 | drop `from=` in the writer |
-| A14 | let the writer touch a line outside the tag pattern |
-| A15 | drop `O_NOFOLLOW` on the user file |
-| A16 | drop one group from the writer's refused list |
-| A17 | drop the user pattern check before the path use |
-| A18 | treat a `privileged` entry as enough without `users` |
-| A19 | let the writer accept a sudo user not in `privileged` |
-| A20 | trigger: drop the `body.operation` arm, so the consume record passes from a session |
-| A21 | trigger: accept actor_role NULL with any actor_run |
-| A22 | a grant reader drops the `kind = 'action.allowed'` or actor filter. The runner splits it: A22a drops the kind, and G21's `action.refused` look-alikes kill it. A22b drops the actor, which the trigger can't stand in for, because 3i-3j adds the trigger without checking old rows. Its killer is the grant-migration test "A22b, sage-1703": a session-written `grant.host.removed` with `hostLineLeft` and a `grant.host-enroll` row from 3i, migrated to 3j, where `hosts.remove` still removes the host and `reconcileGrants` ends nothing |
-| A23 | `host.run` skips the Approve record check (any `host_grants` record is enough) |
-
-Row b keeps the rest of r6's list: the `ready` check, the three hash compares, the definition check, the
-install and record order, `remove` on a verify failure, both start sweeps, the reconcile's remote `remove`,
-the `grant.step` before install, revoke leaving the record, `register` before `issue`, the abort check and
-the `await` before `issue`, revoke and an unreferenced claim, `sweep` and any `mosaic-` line, revoke's host
-step order, claim before consume, the resolved unspent grant decision, an async `commit`, `hosts.revoke`
-through `credential-verbs.mjs`, the revoke marker reconcile, the upsert, the undo past `grant.revoked`, the
-abort after step 5 and a missing `bus.tester` as dev.
-
-## Broker functions this row touches (sage-1677)
-
-For row 236 (Megavolt), which rebuilds on this landing. Old lines are `packages/bus/src/broker.mjs` at
-8fede5fc6, new lines are at the last commit that changed this file (they moved by 10 after `runEnrollment`
-went in). The planned list is kept in this file's history (827b89ea6).
-
-Changed:
-- `constructor` (:279): one more option, `hostGrant`, the object `host-grant.mjs` builds.
-- `recordEvent` (old :1243-1251, new :1606): one more refusal. An `action.allowed` whose `body.action` or
-  `body.operation` is a `grant.*` name refuses `reserved-event`.
-- `request()` (old :1362, new :1726): two routes ahead of the sync path, a `decision.raise` with `grant` to
-  `#raiseGrant` and the `hosts.*` verbs to `#requestHosts`. Both are async.
-- `requestHost` (old :1712-1795, new :2079): the business-file lookups (old :1730-1736) become one
-  `#hostAccess` call, in the same transaction as `#agent`. `commands` and `entry` come from it.
-- `#dispatch` (old :1796, new :2160) gets a fifth parameter, `enroll`, which only `#raiseGrant` passes.
-  - `decision.raise` (new :2244): `grant` joins the allowed keys, and `grant` without `enroll` (or the
-    reverse) refuses `invalid-request`. The `host.sudo` block reads `#hostAccess` in place of `b.hosts`
-    and the role's `hosts`, and an undefined `target` still refuses `host-unknown`. `validArgv` and
-    `validStdin` now run after the access check, so a malformed argv for an ungranted host refuses
-    `host-not-granted` first. The enrollment block is appended to the question before `string(question)`,
-    so the 4096 cap counts it (M1). The decision's raise body carries `grant: enroll`.
-  - `decision.resolve` (new :2409): when `op` is `resolved`, `#approvedGrant` reads the decision, and a
-    `host-enroll` grant starts `#runEnrollment` from `setImmediate`, after the transaction commits. The
-    result adds `grant: 'started'`.
-
-New, all private but two:
-- `#grantEvent` (:657), the writer of guarded events. It runs the secret check, then `writeGrantEvent`.
-- `#approvedGrant` (:667), `#consumeGrant` (:678). `#consumeGrant` sits after `#approvedGrant`, not next
-  to `#consumeAuthority` as planned.
-- `#hostRecord` (:685), `#hostAccess` (:692), `#grantNotice` (:708), `#enrollFailed` (:736),
-  `#runEnrollment` (:750), `#openGrantDecisions` (:823).
-- `runEnrollment` (:745), public, a trusted entry to `#runEnrollment` for G10. No verb reaches it.
-- `reconcileGrants` (:833), public, which `runtime.mjs` calls once at start.
-- `#raiseGrant` (:866), `#hostsCaller` (:886), `#requestHosts` (:900), `#hostLinesLeft` (:964).

-Module level, new (:184-230): `GRANT_RUN`, `grantName`, `GRANT_EVIDENCE` (the N1 filter as SQL),
-`registrySha256`, `writeGrantEvent` (exported, the one writer of guarded events, which test fixtures use
-for F1), `HOSTS_VERBS`, `fingerprintOf`, `INSTALLER_COMMENT`.
-
-Unchanged: `#event`, `#spent`, `#consumeAuthority`.
-
-Other `src` files:
-- `bus/src/host-grant.mjs`, new: the keyscan, the installer key pair, and `hosts.check`'s `list`.
-- `bus/src/runtime.mjs`: builds `hostGrant`, calls `reconcileGrants` before the server starts, and adds
-  the `host_grants` references before `new Credentials` (X4 third bullet).
-- `bus/src/host-run.mjs`: `runHost` takes `command`, sent as is in place of the sudo argv, for the
-  installer's `list`.
-- `bus/src/server.mjs`: the `hosts.*` verbs and a raise with `grant` go down the async path.
-- `bus/src/store.mjs`: the 3i-3j step, `SCHEMA_VERSION` 3j. `bus/src/credentials.mjs` exports
-  `privateDir`.
-- `business/src/business.mjs` and `business/src/hosts.mjs`: the loader refuses `hosts` (S1).
-  `checkHosts` and `checkHostGrants` are gone.
-- `cli/src/hosts.mjs`, new, routed from `cli.mjs` and `scripts/mosaic`.
-
-## Decisions taken in the build
-
-- **`#hostAccess` binds the agent and the host.** X4 says the Approve record check passes when the
-  decision is an approved `host` grant with a `grant.host` consume. The check also requires the grant's
-  `agent` to equal the session's role and its `host` to equal the requested host. Without that, an
-  approved grant for one agent and host would vouch for any `host_grants` row that names its decision.
-  Cost: none for row b, whose executor writes the row from the same grant.
-- **Store fixtures are written the real way.** `bus/tests/host-fixtures.mjs` inserts the decision rows by
-  SQL, but every guarded event goes through `writeGrantEvent`, so the trigger sees it (F1). An enrollment
-  fixture writes `grant.host.enrolled`, or the start reconcile reads it as interrupted.
-- **The resolver test for host kinds is gone.** `business/tests/hosts.test.mjs` lost its D5 case, because
-  the loader now refuses `host.<id>` credential refs. The `isHostKind` filter in `business/src/resolve.mjs`
-  can't be reached now. I left it in, since row b may want it back, and it's one line.
-- **Store before Credentials.** The runtime already opened the store before `Credentials`. The
-  `host_grants` references depend on that order, and the comment there says so.
-- **CLI.** `mosaic hosts` prints tab lines, and `--json` prints the bus rows. Usage errors exit 4 and bus
-  refusals exit 2, as `mosaic credentials` does. There is no enroll command: enrollment is the chief's raise.
-- **Host tools tests live in the bus suite.** `bus/tests/host-tools.test.mjs` loads the writer by path
-  through a Python harness under `python3 -B -I`. The harness passes its own key dir, config dir, owner
-  uid and user, group and sudo lookups, and runs `mosaic-keys` from a copy with stub `sudo` and `logger`.
-  The gate runs the bus suite, so G16 and G25 run there. The real `pwd`, `grp` and `sudo -l` paths are
-  checked on the #433 VM, not here. The test also runs `visudo -c` on the sudoers file and `sshd -T` on
-  the drop-in.
-- **Writer details the design left open.** The `from` file must hold exactly one value matching
-  `[0-9A-Za-z.:/*?!_-]+(,[0-9A-Za-z.:/*?!_-]+)*`, so it can't close the quote. `users`, `privileged` and `from` must be
-  regular, owned by the owner uid and not group or world writable, and are opened without following a
-  symlink. Lines starting with `#` are comments. A refusal exits 1 with its code on stderr and in syslog.
-  `add` of a tag that is already there exits 0 and writes nothing.
-- **`runEnrollment` is public for G10 (duckworth-0081 B1).** G10 needs a second start for a spent
-  decision, and the resolve path can't give one: a second resolve refuses `decision-closed`
-  (broker.mjs:2416) before the executor runs. So
-  `#runEnrollment` returns its code (`enrolled`, `host-enrolled` or the refusal), and a public
-  `runEnrollment` calls it, as `reconcileGrants` is public. The test checks a spent
-  decision gives `decision-consumed`, and an open or agent-resolved one gives `not-authorized`, with
-  nothing written. That second case also reaches the `via` and `by` checks in `#approvedGrant`, so A3 is
-  no longer vacuous (N1).
-  Who can call it (sage-1692): only code holding the `Broker` object, which is the bus process and the
-  tests. The one `new Broker` in `src` is `runtime.mjs:126`, and no `src` file calls `runEnrollment`;
-  the resolve path calls the private `#runEnrollment` from `setImmediate` (broker.mjs:2445). A seat
-  holds no `Broker`. It reaches the bus only over `broker.sock`, where `server.mjs` calls a fixed set of
-  methods by name (`request` at :134 and :140, `identity`, `disconnect`). `request()` routes on the verb
-  through the `#dispatch` switch, and neither file looks a method up by name (no `this[` in either), so no
-  verb string can reach `runEnrollment`.
-- **A `sudo -l` that times out refuses `user-sudo` (N2).** `_sudo` returns an empty answer on
-  `TimeoutExpired`, which isn't the expected line, so `main` logs the refusal and exits 1.
-- **Keyscan comment (N3).** A scan that can't start refuses `host-failed`. One that runs and finds no key
-  returns no lines, and the raise refuses `host-key-mismatch`. The comment in `host-grant.mjs` now says so.
-- **No tag on in-run `grant.failed` (N4).** r6:578 tags only the `interrupted` one, so the code follows it.
-- **Run sheet (N5).** The writer refuses `config-privileged` when the file is missing, so each host needs an
-  empty, root-owned `/etc/mosaic-keys/privileged` (0644) before the first enrollment.
-
-## Mutant results (Sage's slot, 2026-10-21)
-
-All 25 killed: A1 to A23, with A3b added for duckworth-0083 N8 and A22 split into A22a and A22b. The
-runner is `mutants.py` outside the repo. Each mutant gets its own session, a 420 s limit with a group kill,
-and a byte restore checked against git status. None hung. Run 1 (04:24Z, on 95f966b1c) killed A1 to A22a
-and stopped at A22b, which survived. Run 2 (04:43Z, on 097892741) killed A22b and A23.
-
-- Each kill comes from a named assertion in the mutant's own test files, except A9. Dropping the `hosts`
-  primary key leaves `host_grants`' foreign key with no parent key, so the store refuses to open
-  ("foreign key mismatch") and 28 of 29 tests fail at setup. That's a structural kill, not the S1 test.
-  The schema can't exist without the key (sage-1709).
-- A22b drops the actor filter from `GRANT_EVIDENCE`. The trigger can't stand in for it, because a 3i store
-  can hold a session-written grant row that the 3i-3j step keeps. The grant-migration test "A22b,
-  sage-1703" kills it (see the A22 row above).
-
-Follow-up, not in row a: G18's control calls `runHost` directly, so nothing runs `hg.check` end to end
-with a good pin (duckworth-0083 N9). The #433 VM run covers it.
-
-## Status at 097892741
-
-Done: every Split item, 1 to 8, duckworth-0081 B1 to B3, duckworth-0083 N8, and all 25 mutants killed.
-
-Single files in the slot, all exit 0, 178 pass and 0 fail by an awk sum over 23 logs: bus grant-enroll
-24, host-run 24, grant-migration 6, host-tools 6, account-migration 3, chief-of-staff 18,
-comment-migration 5, hard-waits 13, name-migration 1, project-runtime 3, spec-migration 1,
-thread-migration 3, usage-migration 1, project-files 8, spec-socket 6, spec-review 12, land 17, spec 4;
-harness spec-tools 2, raise-domain 2; business hosts 4; cli hosts 5; seat sandbox 10.
-
-Left: Sage runs the whole bus, business and cli suites and every `scripts/test-*.sh` at the landing gate,
-after Duckworth approves.
-
-## Round 3 (sage-1742): two tests that count the schema
-
-The landing gate failed `packages/bus/tests/schema.test.mjs:522`. It counts the tables and triggers that
-`schema.sql` creates, and row a adds two tables and a trigger, so the counts go from 16 to 18 tables and
-from 70 to 71 triggers. My singles didn't run it because I took it for a test of other rows' tables.
-
-I grepped `packages/*/tests/*` for `sqlite_master` and `schema.sql`, with `schema.test.mjs:517` as the
-positive control. That turned up one more test that would fail: T46 in
-`packages/cli/tests/stack-release.test.mjs:910`. It puts every schema table in exactly one of four lists, and
-hosts and host_grants were in none. I'd left the stack-release tests out of the r2 singles on the claim that
-they don't load the bus, but T46 reads `schema.sql`. Both tables go in its untimed list (Sage's ruling,
-sage-1745: the message_threads pattern). Neither has an `at` column. Row a writes hosts at five lines,
-and each runs in one store transaction with a `grant.*` events row, which the restore guard counts.
-`#grantEvent` (broker.mjs:657) writes that row through `writeGrantEvent` (:201, INSERT INTO events at
-:212).
-
-- :737 DELETE, in `#enrollFailed`, with grant.failed at :738. Both callers wrap it in a transaction,
-  :816 and :849.
-- :763 INSERT, in the step 1 transaction (:754), with grant.host.enroll.step at :761.
-- :783 UPDATE installer_fingerprint, in the step 4 transaction (:780), with grant.host.enrolled at :784.
-- :932 DELETE, in the hosts.remove transaction (:927), with grant.host.removed at :933.
-- :950 UPDATE state ready, in the hosts.check transaction (:944), with grant.host.checked at :951.
-
-Row a writes no host_grants rows. It only reads them (broker.mjs:695, :930, runtime.mjs:103). Row b adds
-the writes, and each must share a transaction with a `grant.*` event the same way. That goes on row
-235's carry list. The other hits pin an older schema
-(account, comment, name, spec, thread and usage migrations, chief-of-staff 3c) or count only their own
-tables (state.test.mjs:106 reads every table but pins no list, threads.test.mjs:129).
-
-hosts and host_grants are mutable by design, so the refused-labels loop above `schema.test.mjs:517` gets no
-entry for them. hosts.check updates a host to ready. hosts.remove and a failed enrollment delete the
-record. Row b updates and deletes grant records. Neither table has append-only triggers. The one new
-trigger, events_grant_actor, guards events. grant-migration.test.mjs tests it, and it killed mutants
-A20 and A21.

-# Row 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.

-- `#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.
-

-| B1 | drop the chief check on a host grant raise | grant-host (G1) |
-| B2 | start the executor on a `credential.mint` with no `grant` | grant-enroll (A2), grant-executor |
-| B3 | skip the `ready` check at the raise | grant-host (G19) |
-| B4 | skip the `ready` check at step 1 | grant-executor |
-| B5 | skip the definition hash compare | grant-executor (G9) |
-| B6 | drop the definition check (`host-not-declared`) | grant-host (G2), grant-executor (G9) |

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

-## 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.

-
-## 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:

-Its filter `includes("per-channel prompt")` also matched the "profile chet: no per-channel prompts"

-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

-213 landed as 361ba2387, with the same `git patch-id --stable` as r4 2b3e67e36, f313e69b6f7e. The
-refactor tip was 62ddc96cc. I cherry-picked 2d7a99aee onto it under the new branch gosalyn/c2-20-r2 as
-48f044ccc. The patch-id is eb094ae783e9 before and after. None of the 22 paths changed between 2b3e67e36
-and 62ddc96cc. The fence export from sage-1836 Q1 was already in the commit: `personaTextFault` from
-packages/harness/src/bundle.mjs, called by the script. I checked the test list again on the new base by
-grepping tests and scripts/test-*.sh for each non-test path's basename. The new hits name other packages'
-package.json files or write lockfiles in temp dirs, so the 18 files stand. 231 landed after that as
-29ce1e360. It touches only packages/library and the queue-231 packet, none of these 22 paths.
-
-Rerun on 48f044ccc, slot grant sage-1932, 10:18:09Z to 10:30:14Z, after a busy check. All 18 files ran
-whole, one `node --test` each, every rc 0: 419 pass, 0 fail, 0 cancelled, summed by awk. That's two more

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

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

-§ 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 |

-| Owner must be `mosaic`: git gets no global config | `packages/seat/src/checkout.mjs:79-89` (`GIT_CONFIG_GLOBAL=/dev/null`, `GIT_CONFIG_NOSYSTEM=1`). The dubious-ownership refusal is git's own behaviour |
-| Bus mirror path `<dataRoot>/projects/<business>/<project>` | Brief:300; `packages/project/src/paths.mjs:34-40` |
-| C2-04 and C2-03a not landed | `grep` of `packages/*/src` finds no library entry handling or `refs/heads/served`; `docs/guides/host-run-sheet.md:269` says "not landed" |
-| Served ref `refs/heads/served` | D:963 (7.2); Brief:676 |
-| Token kept out of URL, config, argv, logs | D:955-956 (7.2) |
-| Mapping file is the entry alone; `remote`, `branch` required | `survey.mjs:114-116`; `mapping.mjs:38-47` |
-| Output lines and fields | `survey.mjs:83-97`; data from `:26-76` |
-| Folder lines list folders that directly hold an entry, full path | `survey.mjs:30-35` |

-
-## Code and design disagreements
-
-1. Design 1.1 shows the mapping nested in `"projects": {"books": {...}}` (D:412-429). The survey's
-   `--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.

-  194 has landed with a green full gate (15 packages, ten script suites), NEW is the 194 landing and P3 also runs

   `--sso` included, from `status` after that window.

-   without the flag it refuses `no-backup`. Exit 0 with `--no-rehearsal`
-   refuses `rehearsal-required`; any other exit refuses `rehearsal-failed`.
-5. A2 stops the Console, then the bus, and waits for both to read inactive
-   or failed. A3 is `activate --units external`, A4 the render with the new
-   `--copy` (which also starts the bus, then the Console), A5 `confirm`.
-   The driver writes the new args file beside the old one before A2
-   (`args-failed`, exit 3) and moves it into place after A5. A failed move
-   exits 5 `args-failed`: the new copy is live and confirmed, the args file
-   still names the old one, and root moves the new file (the result line
-   names it) into place by hand.
-
-A failure in A2 or a stage that exits 3 starts the old units again and gates
-them (A2f). A later failure stops both units, runs `revert`, renders the old
-copy and runs `confirm --rollback OLD --cause A3|A4|A5`. `rollback` is the
-same from A1 on, with `rollback BUSINESS --to ID`, no fetch, no copy and no
-rehearsal; `--restore` and `--events` pass through.
-
-Root reads no output the stack user wrote except exit codes and the
-rehearsal's `BACKUP_STORE` line, which it copies into its log after a match
-against a fixed pattern (`BACKUP_STORE none` otherwise). The step log
-`/var/log/mosaic-stack/upgrade-dev.log`, 0640, gets one
-`<time> <step> rc=N argv: ...` line per step and a last
-`<time> result exit=N <code> <text>` line.
-
-Exit 0 ok, 1 failed with the old stack running and gated, 2 rollback-failed
-with both units stopped, 3 refused with nothing stopped, 4 usage, 5
-args-failed with the new stack live and confirmed. A refusal
-after step 2 leaves the user's clone fast-forwarded and the new copy made. After exit
-2 the activation stays open, so the next run's plan refuses until root
-finishes it.
-
-#### Root's host check (`scripts/case1-hostcheck.sh`, row 240)
-
-```
-/usr/local/lib/mosaic-stack/hostcheck.sh --check | --enforce | --upstream
-```
-
-Installed from `scripts/case1-hostcheck.sh` as `hostcheck.sh`, with
-`scripts/case1-pins.sh` beside it (`docs/guides/host-run-sheet.md` section 4).
-The pins are the profile's sha256, the `apparmor-profiles` version it came
-from and the bubblewrap install pin; changing one is a reviewed commit.
-Seven items, one `ok N` or `FAIL N` line each: the profile file matches the
-pin and no package owns it; `aa-status` has `bwrap` and `unpriv_bwrap` in
-enforce mode and no `mosaic-bwrap`; no other file under `/etc/apparmor.d`
-names `bwrap`; a bwrap child under the units' no-new-privs reads
-`bwrap//&unpriv_bwrap (enforce)`; `/usr/bin/bwrap` is `root mosaic 0750` by
-the statoverride and by `stat`; the user-namespace restriction and
-`fs.protected_hardlinks` are 1; `net.ipv4.ip_unprivileged_port_start` is
-above the Console unit's `--port`, or above 1023 with no unit. A `note` line
-says whether bubblewrap is the install pin and never fails.
-
-`--check` exits 0 or 1; `stack-upgrade.sh` refuses `profile-drift` on 1.
-`--enforce` exits 0. On a failure, or while `/etc/mosaic-stack/DRIFT` exists,
-it unloads the profile if loaded, sets `/usr/bin/bwrap` to `root:root` 0700,
-appends the failed items to `DRIFT` and one line to
-`/var/log/mosaic-stack/hostcheck.log`. It never writes the statoverride. The
-apt hook runs it after every package run, and `mosaic-hostcheck.service`
-(`packages/cli/systemd/`) at boot before the bus. `--upstream` compares the
-`apparmor-profiles` candidate's profile to the pin, prints any difference
-and exits 0, or 1 when the download fails. Exit 2 is usage or a refusal:
-root takes no `--root` (the test seam), and other users run only with it.
-
-#### Root's acceptance run (`scripts/case1-accept.sh`, row 195)
-
-```
-case1-accept.sh --business ID --args FILE --claude-pin PIN --node-pin vN.N.N
-```
-
-Root runs it on the Case 1 host after the install window, from a root-owned
-checkout. It reads the user, home, copy, node, claude and both ports from the
-args file (`/etc/mosaic-stack/dev.args` on .53), which must pass
-`stack-upgrade.sh`'s rules, say `--profile factory` and name `--business`.
-Every command that runs the stack's code runs as
-`sudo -u USER -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin` from `/`.
-Root only reads systemd, `ss`, `/proc`, the account database and file
-metadata. The one write is F3's message and its reply, and it never opens
-`claude-session.env`.
-
-It prints one line per check, `<id> <path> <mark> <evidence>`, then
-`count <mark> N` for each mark and a result line. The functional checks
-F1-F11 are `pass` or `FAIL`: both units active as the user, the Console on
-127.0.0.1 only, a tester message to chief answered, `case2-precheck.sh
---profile factory`, the bwrap labels of a live role session, the claude and
-node pins, one live PM launch, the credential file's owner and mode, the
-autoupdater off, no Discord binding. The host paths P1-P11 are `closed`,
-`accepted <ruling>` (Q182, Q183, mos-1096, mos-1101) or `unnamed`, which means
-no ruling names the path; each `unnamed` line goes to Mos. P9 runs
-`hostcheck.sh --check`, never `--enforce`.
-
-Exit 0 when every F check passes, 1 when one fails, 2 on usage or a refusal:
-a bad args file, or `--root` misused. A P check never changes the exit.
-`--root DIR` is the test seam for `packages/cli/tests/case1-accept.test.mjs`;
-root takes none, and other users run only with it. Design: row 195 r7
-section 5 (`agents/darkwing/work/queue-195/DESIGN.md`).

-# 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.
-
-A reply holds at most 10 items and at most 1,200 characters of item text in all. It has at most 5
-ideas of up to 200 characters each. A question, finding or fact runs up to 300 characters. You or
-Jason can ask for lower limits. When an agent can't back an answer with a quote, you see "No cited
-answer" instead.
-
-Each book world stays separate. One item can't mix quotes from two worlds.
-
-You talk to them in the Console. Hermes keeps running until you have moved over, and stopping it is
-your choice.
-
-Five more helpers can join them: ideas, research, proofreader, fact-checker and continuity. You
-choose which ones to start with, and you can add one later.
-
-## What Jason will ask you
-
-He will ask you to confirm your book folders and type folders, which books share a world, the name of
-each playground folder, and which helpers to start with and when.

-# 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.

-# Host run sheet: preparing a host for the stack

-ops-01 runs this on a fresh host before install (I2), and once per host for enrollment. Jason places the
-credentials in section 9. Brief: `docs/plans/2026-10-20_installer-rows.md`, I3 (row 233, #1735). The
-host design is Darkwing's r6 (`agents/darkwing/work/queue-195/DESIGN.md`, section 2) as the brief
-changes it.
-
-The hosts are .53 (profile `factory`) and .54 (profile `library`). Both get every section unless a
-section says otherwise. Every command runs as root unless it starts with `sudo -u mosaic`.
-
-Each item names the `scripts/case2-precheck.sh` line that verifies it. Install's precheck runs as the
-stack's user with `--business ID --profile factory|library`. Where no precheck line checks an item, the
-item says "precheck line missing", and Gosalyn adds the line to I2. Today's precheck (C2-13a) has these
-gaps; C2-13b adds the library lines (`library.sync`, persona modes, no Discord binding).

-## 1. The stack's user and its home

-
-`mosaic` gets no sudo rule and no supplementary group. Check with `sudo -l -U mosaic` (expect "not allowed
-to run sudo") and `id -G mosaic` (one number).
-
-Precheck lines:
-- `ok      HOME is /srv/mosaic`
-- `ok      sudo -n true fails as mosaic`
-- `ok      id -G prints one group (<gid>)`
-- `/srv/mosaic` at 0700: precheck line missing.

-  refuses otherwise at render, which is not a precheck line.
-- The installed version equals the pin: precheck line missing.
-
-## 3. claude, factory only (.53)
-
-Root installs it under `/opt`, never under the stack's home (this replaces r6's `/srv/mosaic/.local/bin`).
-The pin is 2.1.304 unless the window names a newer one.
-
-```sh

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

-else on the host gains user namespaces.
-
-The drift stop (row 240, I4, #1746) goes in last, after the profile and the statoverride. As root, from
-the root-owned checkout of the reviewed commit:
-
-```sh
-install -d -o root -g root -m 0755 /usr/local/lib/mosaic-stack
-install -o root -g root -m 0755 scripts/case1-hostcheck.sh /usr/local/lib/mosaic-stack/hostcheck.sh
-install -o root -g root -m 0644 scripts/case1-pins.sh /usr/local/lib/mosaic-stack/case1-pins.sh

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

-leaves.

-`stack-upgrade.sh` stops and starts both units itself.

-

-- 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.
-- The mkdir race refuses with the named reason. A stubbed mkdir that throws EEXIST is enough.
-- One mutant for each of the three fixes, each killed by its test.

-  (2026-10-21)
-- **The boot host check orders only one business's bus.**
-  `mosaic-hostcheck.service` (row 240) has
-  `[email protected]`. `case2-unit.sh` enables the
-  bus as `mosaic-bus@<business>.service`, so on a host whose business id
-  isn't `mosaic-stack` nothing orders the two. The bus can start before
-  the boot stop runs, and after a boot-time drift role sessions can use
-  bwrap until it does. The fix: `After=mosaic-hostcheck.service` in
-  `packages/cli/systemd/mosaic-bus.service.in`, which orders every
-  instance and does nothing where the unit isn't installed. It goes in
-  before the first install whose business id isn't `mosaic-stack`.
-  Filbert N1 on row 240 (29945, #1746). (2026-10-21)
-- **The run sheet writes the apt hook before the first `--check`.**
-  Section 4 installs `80mosaic-hostcheck`, then runs
-  `hostcheck.sh --check`. If that check fails, the next package run
-  closes bwrap before anyone has read the failure. It fails closed, but
-  it surprises an installer. The fix: run `--check` first, or say what a
-  failure at that step means. Doc-only, for the next row that edits
-  `docs/guides/host-run-sheet.md`. Filbert N2 on row 240 (29945, #1746).
-  Filbert's N3, that a closed bwrap appends to `DRIFT` on every later
-  apt run and boot, is by design; ops-01's STATE read should expect the
-  repeats. (2026-10-21)
-- **The sso-config first-step hint has no business.** When the target
-  copy has no `console.sso`, `stack-release.sh` (`:938`) refuses with
-  "activate $TO without --sso first, then ... activate $TO --sso". The
-  usage line is `activate ID BUSINESS` (`:47`), so pasting either command
-  as printed gives a usage error, not the first step. It fails safe,
-  since the usage error changes nothing. The fix: add `$BUSINESS`
-  (set at `:2138`) to both commands, and the business (`acme`)
-  to the three expected strings in `stack-release.test.mjs`
-  (`:1538`, `:1689`, `:1691`). For a later row that edits
-  `stack-release.sh`. Webby N1 on row 238 r1 (REVIEW-r1.md, 433a95292,
-  #1744). (2026-10-21)
-- **Gate runs mount the host's pi auth file.** `compose.yaml:43` mounts
-  `${PI_AUTH_FILE:-/home/jwoltje/.pi/agent/auth.json}` read-only into
-  the agent container. No suite sets `PI_AUTH_FILE`, so the
-  `test-task.sh` cases that call `scripts/run-task.sh`, and
-  `test-release.sh` through `release.sh` `health_check` (`:41-54`), run
-  Compose with the host file. Row 197's lane `cleanEnv`
-  (`scripts/testing/gate-lane.mjs:109`) keeps the default too: it neither
-  sets nor passes `PI_AUTH_FILE`. The mount is read-only, and the legacy
-  gate already worked this way before row 197. `test-auth.sh` uses its
-  own fixtures but calls `auth.sh`, not Compose. The fix: a fixture
-  `PI_AUTH_FILE` for the Compose-reaching cases, set by the suites or by
-  the lane's `cleanEnv`, and a test that no gate step mounts the host
-  default. It needs its own row. Webby N4 on the row 197 proof driver
-  (bba870ee9), traced by Herb (herb-0051). (2026-10-21)
-- **Lane image prep inspects a base that BuildKit never tagged.**
-  (N7 of the row 197 proof.) After the Compose build,
-  `scripts/testing/lane-image.mjs:41` (`prepareImage`) runs
-  `docker image inspect node:24-bookworm-slim` to put the base digest
-  in the receipt. BuildKit resolves the base from the registry
-  without tagging it in the local store, so on a host without the tag
-  the inspect throws "No such image" after a good build. That
-  happened in Sage's proof try 1 (2026-10-21 09:03Z, run cf48efccf083).
-  The throw fails closed: the run's terminal record is unclean, both
-  lanes quarantine, and `gate-lane.sh recover` clears them. Pulling the
-  base first fixes it, and the receipt digest then matches what the
-  build used (91acba91 both ways). The fix: before the build, inspect
-  the base and refuse with a named reason if it's missing, or pull it.
-  After the build, refuse if the base digest changed. Add a test with a
-  fake Docker that has no base tag. Kept out of row 197 r6 by Sage
-  (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)

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}]}`. |

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.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`. |

-hold enrolled hosts and host grants, and the `events_grant_actor` trigger. The trigger refuses an
-`action.allowed` event whose `body.action` or `body.operation` matches `grant.*` unless its actor
-is `actor_role` NULL with `actor_run` 'grant', the broker's grant writer (#436b section 7). The
-step runs in one transaction, and a failure leaves the store at 3i. The 3i fixture,
-`tests/fixtures/schema-3i.sql`, is pinned from 8fede5fc6's tree, and `tests/grant-migration.test.mjs`
-covers the step and the trigger.
-
 The managed runner calls usage.begin before an actual harness turn and usage.end
 after it, including a failed/stopped turn. Each takes only {turn: deliveredMessageId}.
 The broker requires the bound role holder and its delivery, binds run identity,

-Fixture Hermes home for packages/cli/tests/case2-persona-import.test.mjs (row 221, C2-20).
-The layout follows hermes-agent df5700ebe: the default profile is the root, other profiles sit under
-profiles/<name>, each persona is SOUL.md and channel prompts are in config.yaml. Every value is made up.
-Strings starting "marker-" must never reach the script's output, and files under memories/, sessions/
-and skills/, state.db, profile.yaml, auth.json and .env (the test writes .env, which git ignores) must never be opened.
