+# Re-pin 490e2771d to 4429a104f (row 192, Q175 phase 1), with npm ci in the new copy
+
+Sage, 2026-10-20, draft 1, for mos-1099 item 3 under DECISIONS Q173. Mos checks this file at its commit before
+P0. Any change to this file or to NEW after the check means Mos checks again (mos-0849/0850).
+
+This is a smaller window than `repin-rows-177-185.md` (draft 2, which Mos checked in mos-0929). Where a step is
+the same, this file names that file's step and says what differs. The 7332 matrix, the snapshot, the W9 list and
+the rollback compare are reused unchanged.
+
+## Who, and what nobody does
+
+- Sage operates, as the tester. Darkwing holds the gate lane for row 190 round 3 tonight, so I take the
+  operator seat. Mos verifies each step's output before the next one and runs `rehearse` (P3), which reads the
+  live config and a live backup (`docs/TOOLS.md` `rehearse`: Jason or Mos runs it).
+- Jason has no step. Q173 covers a re-pin of this test system with a backup first and a STATE report after.
+  Nothing is pruned.
+- Nobody acts as Jason: no `--by jason`, no human shell or tmux pane, every bus read and write carries
+  `--tester`, and no request carries `jason.woltje`. `bus.tester` stays as it is; if it isn't `true`, stop at P1.
+- No pi (mos-0865 D2, P19 #383). No Save in the human Console, no `mosaic name`.
+- Outside reach doesn't change. The Console keeps its current flags. `--sso` stays off: row 192's sign-in code is
+  dormant without the flag, and `cli.mjs:57` refuses `--sso` with the preview flags the pointer carries anyway.
+  The proof pair stays unset. The tunnel still forwards 7332 only (P4 and W10 check it).
+
+## Names
+
+- OLD, live: `490e2771d3d057ab76991e2c7859cd251857e64c`, activation `20261020T192956Z-490e2771d3d0`, pointer
+  `pm: true`, schema 3i, Console `--port 7332 --public-host mosaic.woltje.com --auth-header X-authentik-username
+  --allow-user jason.woltje --tester-port 7333` (no `--send`, read from `stack-release.sh status` between 21:36Z and 21:39Z).
+- NEW: `4429a104f6d65ccf165f6c83b5d1dce3147dfde0`, row 192's landing, 103 commits past OLD (`git rev-list --count 490e2771d..4429a104f`).
+  The 106 that `status` showed is OLD to HEAD 305857c8f, so it also counts the three record commits below.
+  The commits after it (5b8def2f1 plans, 176a6bf4b sessions, 305857c8f queue) are records and don't move NEW. If
+  another code row lands before W0 (row 190 is the likely one), NEW stays here unless Mos rules otherwise.
+- REPO: the canonical checkout. `activate` runs REPO's `webui-service.sh`, so the four service scripts are held
+  at NEW for the window (P5).
+- `P=/mnt/storage/scratch/sage-pin-de352dfaf` (`business-check.mjs`, `console-check.sh`, checked against
+  `agents/sage/work/window-plan/repin-de352dfaf/SCRIPTS.sha256`).
+- `WIN=agents/sage/work/window-repin-4429a104f/`, where every transcript goes.
+- `SNAP=$WIN/snapshot.mjs`, a copy of `agents/darkwing/work/window-rows-177-185/snapshot.mjs`, sha256
+  `639fd28a2674aaa03ce824e3394b4052f21cdef7d6fa49bae61a9927ed341e67` (mos-0899). I check the sha before S1, S2
+  and any D3.
+
+## What NEW carries over OLD
+
+The path-limited log over `packages`, `scripts`, `roles`, `contracts`, `adapters`, `skills` and the package files:
+
+| Row | Commit | Live effect |
+|---|---|---|
+| 186 | 269134d8d | Tool only: the activate plan's backup line says what the run will do. |
+| 187 | 9a71e4e80 | Tool: activate sets, carries and drops the proof pair. The pointer has no pair, so nothing changes. |
+| 188 | 8fc0ee216 | Tool: proof file checks on a carried pair. No pair, no effect. |
+| 163 | 8ecc7a239 | Tool: `rehearse`, which P3 uses, and `bus start --no-launch`. CLI `cli.mjs` and `launcher.mjs` gain the `--no-launch` path; the default start is unchanged. |
+| 189 | ace27dc5e | Tool: `activate --no-send`. Live already runs without `--send`; the pointer carries that. |
+| 192 | 4429a104f | Console `--sso` (off here), `scripts/mosaic-config.mjs` load becomes async, `webui-service.sh` renders `--sso` only when given, and a new dependency, oauth4webapi 3.8.8. `cli.mjs` imports `sso.mjs` at the top, so the Console won't start from a copy without that module. |
+
+No schema step: `SCHEMA_VERSION` (`packages/bus/src/store.mjs:17`) is 3i at OLD and NEW, and no migration was
+added. `--plan` must say `migration: none`. No roles, skills, contracts, adapters or plug-in kinds changed. So: no
+harness set, no skill carry, no `pm-on`. One `activate --pm`.
+
+## npm ci in the new copy
+
+mos-1099 asks for npm ci in the new copy. `stack-copy.sh copy` already does it: it extracts the archive to a temp
+dir, refuses without `package.json` and `package-lock.json` (:55), runs `npm ci --no-audit --no-fund` there and
+writes no copy if it fails (:56). W0 checks the result: `node_modules/oauth4webapi/package.json` in the copy reads
+3.8.8, and `node --input-type=module -e "await import('oauth4webapi')"` from the copy exits 0. The live copy is
+163M; `/home` has 30G free (94% used), enough for one more.
+
+## Backups
+
+| Before | Backup | Taken by |
+|---|---|---|
+| W5 | the stopped store, `$DATA/backups/stack/<W5 activation id>/` with SHA256SUMS, DATA_ROOT, SCHEMA 3i, STAMP | `stack-release.sh` (row 185: every activate) |
+| W5 | the rollback set (units, wrapper, pointer) | `stack-release.sh` |
+| W9 | the business file, `cp -p` to `~/.config/mosaic-dev/businesses/mosaic-stack.json.pre-window-<stamp>` with its sha256, as evidence nothing wrote it | Sage, in W0b |
+
+## Before the window (nothing stopped)
+
+| # | Who | Step |
+|---|-----|------|
+| P0 | Mos | The `$P` sha check, as in the 177-185 plan P0. |
+| P1 | Sage | The business file, read only, the same values as the 177-185 plan P1. I report its sha256 now rather than assume the 06:15Z value. `business-check.mjs` for OLD now and for NEW after W0: LOAD_OK both. |
+| W0 | Sage | `cd $REPO && scripts/stack-copy.sh copy $NEW`, in a gap between gate-lane runs, since npm ci is heavy. Then the two npm checks above, and `diff <(git -C $REPO show $NEW:package-lock.json) $COPIES/$NEW/package-lock.json` empty. W0 writes only under `copies/` and changes nothing live, so it moves before P2 and P3, which need the copy. |
+| P2 | Sage | `console-check.sh $NEW` against a stub Console of NEW on a scratch port, once without and once with `--tester-port` on a second scratch port. CONSOLE_PASS both. |
+| P3 | Mos | `scripts/stack-release.sh rehearse $NEW mosaic-stack --backup 20261020T192956Z-490e2771d3d0 --port <scratch>`. It must pass every gate check but the PM's. It stops no unit and writes no pointer. Transcript in `$WIN/p3/`. Correction (mos-1107): `rehearse` starts NEW's Console with only `--port` and `--business`, not the pointer's flags. So Mos also starts NEW's Console by hand with the pointer's flags on two scratch ports and reads healthz and `/api/config` on both, then stops it (`$WIN/p3/flags-check.txt`, `flags-console.log`). |
+| P4 | Sage | The tunnel read, as in the 177-185 plan P4. |
+| P5 | Sage | `git -C $REPO diff --quiet $NEW HEAD -- scripts/stack-release.sh scripts/webui-service.sh scripts/bus-service.sh scripts/stack-copy.sh` and an empty `git status --porcelain` on the same four. Row 190 round 3 touches `webui-service.sh`; if it lands before W5, P5 fails and the window waits for Mos's ruling. |
+| P6 | Sage | The 7332 matrix (a)-(g) on OLD, as in the 177-185 plan, saved as `$WIN/matrix-old.txt`. |
+
+## The window
+
+| # | Who | Step |
+|---|-----|------|
+| W0b | Sage | The business file copy. |
+| W1 | Sage | Idle check (`mosaic agents --business mosaic-stack --tester`, `mosaic launches list`), the start stamp from `date -u`, then S1 `node $SNAP --store "$DATA/bus/bus.sqlite" --held`. |
+| W2 | Sage | `stack-release.sh status mosaic-stack`: pointer on OLD, `pm: true`, 3i, last line ok, unit flags match. |
+| W3 | Sage | `stack-release.sh activate $NEW mosaic-stack --pm --plan`. Must show from OLD to NEW, `migration: none`, the backup line, and the Console line with OLD's flags exactly: no `--send`, no `--sso`, no proof pair, `--tester-port 7333`. Any other difference stops here. |
+| W4 | Sage | The unit reads, as in the 177-185 plan W4. |
+| W5 | Sage, on Mos's go | `stack-release.sh activate $NEW mosaic-stack --pm`. Exit 0, `result ok`, every gate check including `pm_launched`. Record the activation id, the backup path and STAMP, and the backup SHA256SUMS sha256. Then `status`. |
+| W9 | Sage, after Mos verifies W5 | The 177-185 plan's W9 list unchanged, the chief turn and the one `assistant` thread turn included (mos-0929 Q3), plus two lines: the webui journal since the W5 stamp (with `UTC`) has one `Proxy: proxy proof off` and no `Sign-in:` line, and `ls -l /proc/<Console pid>/cwd` names the NEW copy. |
+| W10 | Sage | The browser check on 127.0.0.1:7333 and the matrix again as `$WIN/matrix-new.txt`, identical to `matrix-old.txt`. Then P4 again. Corrections after the window (mos-1135, mos-1137): the matrix line for a file the pin changes isn't "identical". Line (g) serves `index.html`, which row 192 grows by 121 bytes (6470 to 6591), so (g) is 200 non-json at 6575 bytes, not 6454. The two browser checks come from the 177-185 window, before row 192 and before a second thread project. "Only tester forms" now allows `#sign-out` while it is `hidden` and `/api/config` has no `sso: true`. "Chat lists the W9 thread" now reads every `.chat-projects section.panel` list (chat.js:93 renders one per project), not the first. |
+| W11 | Sage | STATE report in `$WIN/STATE.md`, posted on P19 386 and P19 412 and on Gitea #1690. |
+
+## Stop conditions and rollback
+
+The same as the 177-185 plan. Two failures in one window: stop and report (mos-0823).
+
+Rollback: `stack-release.sh rollback mosaic-stack --plan`, then the real run. The previous distinct copy in the
+log is 490e2771d, both are 3i, so no `--restore` and no data loss. OLD takes the same Console flags. The R1 and
+R1post compares are as in the 177-185 plan. A restore past W5 follows that plan's D3 steps, with Mos deciding.
+
+Keep every copy. Prune nothing.
+
+## Questions for the plan check
+
+- Q1: NEW is row 192 alone, not bundled with row 190. Row 190 (several instances) changes `stack-release.sh`
+  and `webui-service.sh` and deserves its own window. I recommend running this one first.
+- Q2: Sage operates instead of Darkwing, who is on the row 190 gate. OK?
+- Q3: W0 before P2 and P3. It writes a copy only. OK?
+
+## What Sage ran for this plan
+
+Read only, 2026-10-20 between 21:36Z and 21:39Z (clock read 21:39:50Z at the commit): `stack-release.sh status mosaic-stack` (pointer, last five log
+lines, unit flags match, 106 commits of drift), `git rev-list --count`, `SCHEMA_VERSION` at both ends, the
+path-limited log, `git diff --stat` on the service scripts, CLI and config loader, `stack-copy.sh:23-56`,
+`webui/src/cli.mjs:15-120`, `docs/TOOLS.md` on `rehearse`, `du -sh` of the live copy and `df -h /home`. Nothing
+live was changed.

+# Re-pin window 490e2771d to 4429a104f (row 192, Q175 phase 1), STATE report (W11)
+
+Operator and tester: Sage. Plan: `agents/sage/work/window-plan/repin-4429a104f.md` at f41729178, sha256
+e1272d1a391e00fb1291d47da9973c0ba342d65fcd42f583ea007e883c1f32b9 (checked before W0b, W9). The plan file in
+this commit carries three corrections made after the window. They are listed at the end, so its sha256 differs
+now. Tool blob 3b068b1546d4 (`scripts/stack-release.sh`). OLD 490e2771d3d057ab76991e2c7859cd251857e64c, NEW
+4429a104f6d65ccf165f6c83b5d1dce3147dfde0. Every stamp below comes from `date -u` or from the transcript `W.txt`
+in this directory. Mos's gos: mos-1113 (W5), mos-1114 (W9 to W11), mos-1128 (W9b accepted), mos-1135 (W10
+browser part), mos-1137 (line g, post W11).
+
+## Outcome
+
+NEW is live for mosaic-stack with its PM, and the store stays on 3i. Row 192's sign-in code is in the copy but
+dormant, because the Console runs without `--sso`. W0 to W10 passed, and nothing was rolled back. W10 stopped
+once on two failed browser checks. I diagnosed both read-only as checks written before row 192, not faults in
+NEW, and Mos passed them (mos-1135). Matrix line (g) isn't byte-identical, for a known cause, and Mos passed it
+(mos-1137). Nobody acted as Jason. There was no `--by jason`, no pi, no Save and no `mosaic name`, and
+`bus.tester` was not touched.

+Before (W2): copy 490e2771d3d0, pm true, schema 3i, activation 20261020T192956Z-490e2771d3d0. Console flags
+`--port 7332 --public-host mosaic.woltje.com --auth-header X-authentik-username --allow-user jason.woltje
+--tester-port 7333`.
+
+After (W5, W9 and W11): copy 4429a104f6d6, pm true, schema 3i, activation 20261020T220206Z-4429a104f6d6. The
+Console flags are the same, with no `--send`, no `--sso` and no proof pair. Bus pid 2950923 and Console pid
+2950925, both since 22:02:08Z. Status shows drift of 6 commits on refactor since the pointer's copy (records).

+backslash. The values are not recorded. The Console's cwd is the NEW copy (W9). The webui journal since W5 has one
+"Proxy: proxy proof off" line and no "Sign-in:" line.
+
+Tunnel: `mosaic-preview-tunnel.service` active, running, MainPID 1317, since 2026-10-13 08:40:19 CDT. The window
+didn't touch it. P4 before and after shows one R: spec, `R:0.0.0.0:7332:127.0.0.1:7332`.
+
+## S1, S2 and the store
+
+S1 (`S1.json`, sha256 a7649760c3439705c8b5f3af26d0c21aea1081c1eb295fd02aef3a642064194b) is W1's held read at

+1a444f5ac0049bc78e397b6928e1008cfe8cbc30989bbf2042b4ed27f56a4173) is the held read after the assistant run
+ended, at 22:21:07Z. Both are 3i. SNAP (`snapshot.mjs`, 639fd28a) was checked before each.

+
+The task_snapshots and task_comment_cursors rows (mos-1128 item 2). The writer is the bus's own Vikunja poll, not
+an agent. `packages/bus/src/process.mjs:104` loads the tasks adapter. Its timer runs `tick` every `pollSeconds`
+(`packages/tasks/src/adapter.mjs:192-197`), and `sync.mjs:169` calls `broker.recordTask` with no cap
+(`packages/bus/src/broker.mjs:1123`). That writes `source 'poll'` with role and run null (`broker.mjs:1159-1174`)
+and the comment cursors (`:1131-1138`). The adapter logs only on an error (`adapter.mjs:115`), so the bus journal
+has no line for a good tick. That's why there's no sync line between 22:05Z and 22:22Z. The rows, read
+read-only after the window:
+
+- task_snapshots 402-404 at 22:05:08Z: P19 436, 435 and 434, all updated 22:04:55-56Z. 405-406 at 22:12:38Z: 438
+  and 437. 407 at 22:17:08Z: 438 again. 408 at 22:19:08Z: 431. All have `source poll`, `via cursor`, role null
+  and run null. These are tracker edits made by seats during the window, which the poll picked up.
+- task_comment_cursors 216-220: tasks 424, 432, 438, 431 and 436, last comments 397 to 401. These are the
+  comments seats posted on P19 in the same minutes (398 is Mos's comment on #432).
+
+Rows after S2 (task_snapshots 409 at 22:33Z, cursors 221-223) are the same poll and are outside the window.
+
+## W9 output
+
+- Status, console-check (CONSOLE_PASS), the journal counts, the Console cwd and one running chief from this
+  start (r097436c91816) all passed.
+- `talk chief --tester` (c5b43f04): the chief replied that a tester message authorizes nothing and it took no
+  action.
+- Project `window-20261020-2205`, thread 446201de-e8b5-4df3-9356-d0d5422cc899. `talk --thread` (b4b66ced) got one
+  assistant reply from run r497f1c817d4d. `thread read` shows the tester REQUEST and the assistant RESULT.
+- `threads`, `names` (empty) and `usage` read fine. The human-thread probe was skipped: S1's one thread is the
+  177-185 window's tester thread d0ba7a66, so no human thread exists.
+- W9b: the launcher logged launch at 22:06:00.766Z, thread-idle at 22:21:05.149Z and end at 22:21:05.171Z
+  (reason stopped, exit 0). Nobody stopped it by hand.
+
+## W10
+
+The browser check (`w10-browser.mjs`, dda57ccf) ran against 127.0.0.1:7333 with fetch and XHR limited to GET and
+HEAD. It made no writes and sent no W9 thread request. 10 of 12 checks passed. The two that failed:
+
+1. "Only tester forms": `#sign-out` was in the list. It is row 192's form at `packages/webui/src/public/index.html:12`,
+   `hidden`. `app.js:479` shows it only when `/api/config` has `sso: true`. The live config has no `sso`
+   key, and the form stayed hidden.
+2. "Chat lists the W9 thread": the check read only the first `ul.chat-thread-list`. `chat.js:93` renders one list
+   per project, and W9 made the second project. The diagnosis (`w10-diag.mjs`, 42d0844b) read every panel and
+   found 446201de listed.
+
+Both checks come from the 177-185 window (Darkwing's `window-rows-177-185/w10-browser.mjs`), written before row
+192 and before a second thread project existed. Corrected, they now read:
+
+- Only tester forms, allowing `#sign-out` when it is `hidden` and `/api/config` has no `sso: true`.
+- The W9 thread is in some `.chat-projects section.panel` thread list, not only the first.
+
+Both corrections are in the plan's W10 line, for the next window that copies this one.
+
+The matrix (`matrix-new.txt` against `matrix-old.txt`). Lines a to f are byte-identical. Line g is 200 non-json
+both times, but 6454 bytes on OLD and 6575 on NEW. `index.html` is 6470 bytes at 490e2771d and 6591 at 4429a104f,
+121, and the only hunk is the line 12 form. The served page grew by the same 121. The plan's W10 line now says a
+line for a file the pin changes isn't "identical", with this case as its example. P4 again at 22:31:29Z: PASS.
+
+## Failed user units (mos-1128 item 3)
+
+All three predate the re-pin at 22:02Z and come from the legacy `~/.mosaic` and jarvis-brain setup, not the
+stack. P19 #393, "dragon-lin: seven legacy user units in failed state", covers all three (filed by Mos on
+10-20 at about 01:42Z). It has no comments yet. The current failure times are later than the ones #393 lists,
+so I added a comment with them. Times are from `systemctl --user show` (CDT) with UTC alongside.
+
+| Unit | Runs | Failed | #393 |
+| --- | --- | --- | --- |
+| mosaic-standup-pm.service | `~/.mosaic/tools/coordinator/standup_trigger.py pm` | 2026-10-19 19:00:28 CDT (10-20 00:00:28Z), exit 1 | listed |
+| mosaic-install-drift.service | `~/src/jarvis-brain/scripts/alerting/mosaic-install-drift` | 2026-10-20 00:12:54 CDT (05:12:54Z), exit 9 | listed, with an older time |
+| mosaic-unit-failed@mosaic-reconcile.service | `~/.local/bin/mosaic-unit-failed mosaic-reconcile.service` | 2026-10-20 13:16:12 CDT (18:16:12Z), exit 4 | listed, with an older time |
+
+The marker's journal at 18:16:12Z says the escalation's tmux send to jarvis failed ("tmux target not found",
+socket mosaic-fleet), so the page wasn't delivered. The record is on disk in
+`~/.local/state/mosaic-unit-failures/20261020.jsonl`. `mosaic-reconcile.service` failed at that time (exit 7)
+but last ran OK at 17:16:27 CDT (22:16:27Z). The marker stays failed until something resets it. The journal no
+longer has lines for the other two units. The window changed none of these units, and touching them is
+outside it (`~/.mosaic` is off limits, and #393 needs Jason or ops-01's charter to disable any). W11's list also
+shows `setspark-tmp-guard.service` failed. It belongs to another project, and I've left it.
+
+## Corrections to the plan, made after the window
+
+- NEW is 103 commits past OLD (`git rev-list --count 490e2771d..4429a104f`), not 106. The 106 in `status` was OLD
+  to HEAD 305857c8f, so it also counted the three record commits.
+- P3: `rehearse` starts NEW's Console with only `--port` and `--business`, not the pointer's flags. Mos's
+  separate flags check covers that (`p3/flags-check.txt`, `p3/flags-console.log`). The line was wrong as
+  written (mos-1107).
+- W10: the matrix line g size change and the two corrected browser checks, as above.
+

+// Merged window B+C, S1, S2 and D3 (repin-merged-bc.md "S1 and S2"): a read-only snapshot of every
+// table in a bus store, so the 3h to 3i migration and a restore can be checked without the bus.
+// OLD's broker doesn't take --tester on usage, names or threads.
+//
+// usage: node snapshot.mjs --store /abs/bus.sqlite (--held | --stopped) [--after STAMP] [--backup /abs/bus.sqlite]
+//   --held     the running bus holds the store: a plain readOnly open, which adds no file to a WAL
+//              store that already has -wal and -shm (as stack-release.sh does for a held store).
+//              Refuses store-not-held when either is absent
+//   --stopped  the bus is stopped: refuses store-unclean when -wal or -shm is present, else opens
+//              with immutable=1 and readOnly, which creates no file and leaves the store's mtime
+//              and sha256 alone
+//   --after    also counts each timed table's rows with `at` after STAMP (mos-0838 D3, before a
+//              --restore). STAMP is a backup's STAMP file, in now_ms form (stack-release.sh:43,
+//              2026-10-20T00:11:14.123Z). The count is a text compare, as the tool's own heldcount
+//              does, so every `at` in every timed table must have that form: a table with any
+//              other value refuses at-format and names the table (sage-1125)
+//   --backup   also compares every table with a stack-release backup's bus.sqlite, which opens as
+//              --stopped opens a store: immutable=1 and readOnly, refusing backup-unclean when -wal
+//              or -shm is present, so nothing writes into the backup set
+//
+// It prints one JSON object: the schema version, then for every table in sqlite_master (type
+// table, less sqlite_*) the row count, the max seq and a sha256 of the rows (in seq order, else in
+// column order). `untimed` names the tables with no `at` column. For usage_records it adds per-run
+// input and output sums, counted as `mosaic usage` counts them (usage.mjs turnRecords). messages
+// and message_threads hold bodies and names, so they print counts only, no sha256 (sage-1125). It
+// prints counts, hashes and table and meta key names only: no message body, no instance, project
+// or thread name, no credential and no file content. It reads no config: the store path is always
+// given.
+//
+// With --backup, each table gets `vsBackup` and `stopTables` names every table other than events
+// whose rows differ from the backup's (sage-1123): a row with `at` after STAMP, a row past the
+// backup's max seq, a changed row at or below it, a changed untimed table, or a table only one
+// side has. meta counts only when a key other than schema_version and schema_digest changed (the

+## Stack instances (`--instance NAME`, row 190)
+
+Several stacks can run on one host, each with its own config, data root,
+units, Console port and CLI wrapper. The default instance is today's stack
+and keeps every name it had. A named instance is created once:
+
+```
+scripts/bootstrap.sh --instance NAME
+```
+
+NAME matches `^[a-z][a-z0-9]{1,15}$`; anything else exits 4
+(`instance-name-invalid`), and `--instance dev` is the default. Bootstrap
+writes `~/.config/mosaic-NAME/config.json` (0644) and claims `~/.mosaic-NAME`
+with the marker `instance.json`, `{"instanceVersion":1,"name":"NAME"}`. It
+creates either directory 0700; one that already exists keeps its mode. It refuses with exit 3 and writes
+nothing when the root exists, is not empty and holds no marker naming NAME.
+A second run changes nothing. `~` is the home of the OS user that runs the
+instance.
+
+`--instance NAME` is taken, once and in any position, by `bootstrap.sh`,
+`bus-service.sh`, `webui-service.sh` (all but `copy`), `discord-service.sh`,
+`stack-copy.sh` (`wrapper` and `check`) and `stack-release.sh`. Copies serve
+every instance, so both `copy` verbs refuse it with exit 4. Inside a process the config
+travels as `MOSAIC_CONFIG`. Selection, checked before any read or write:
+
+| Given | Config | Names |
+|---|---|---|
+| neither | `~/.config/mosaic-dev/config.json` | the default's |
+| `MOSAIC_CONFIG` only | that file | the default's |
+| `--instance NAME` only | `~/.config/mosaic-NAME/config.json` | NAME's |
+| both | must be one file (a symlink to it agrees), else exit 4 `instance-config-mismatch` | NAME's |
+
+Every selection checks the data root's marker. A named instance whose root
+lacks its own marker refuses `instance-root-unclaimed`; a root whose marker
+names another instance refuses `instance-root-mismatch`, also when a config
+reaches it with no flag. Both exit 3 before anything is read or changed. A
+missing config exits 3 with the bootstrap command that creates it.
+
+| | Default | Instance NAME |
+|---|---|---|
+| bus unit | `[email protected]` | `[email protected]` |
+| Console unit | `mosaic-webui.service` | `mosaic-webui-NAME.service` |
+| Discord unit | `[email protected]` | `[email protected]` |
+| CLI wrapper | `$BIN/mosaic` (Q81 marker) | `$BIN/mosaic-NAME`, marker `# mosaic-cli wrapper, instance NAME (row 190)`, exports `MOSAIC_CONFIG` |
+| bus session env | `%h/.config/mosaic-dev/secrets/claude-session.env` | `~/.config/mosaic-NAME/secrets/claude-session.env` |
+| Console port | `--port`, 7332 when absent | `--port` required; 7330, 7332 and 7333 exit 4 `port-reserved` |
+
+A named instance's units add `Environment=MOSAIC_CONFIG=<its config>` and
+` [NAME]` after the Description, and the Console unit's comment on the
+variables it sets names `MOSAIC_CONFIG`. The default's renders are
+byte-identical to the templates' renders before row 190. `stack-copy.sh
+wrapper --instance NAME` creates `$BIN/mosaic-NAME` or replaces one that
+carries NAME's marker, and refuses any other file. `check --instance NAME`
+needs `--business ID`, and fails with `CLI: <copy> (MOSAIC_CONFIG mismatch)`
+when the wrapper does not export NAME's config.
+
+For every instance, a Console `--port` or `--tester-port` that another
+installed Console unit in the unit directory already takes refuses
+`port-claimed`, naming that unit: `webui-service.sh install` exits 1, and
+`stack-release.sh activate` and `rollback` exit 3 before anything stops
+(`--plan` lists it). A unit with no `--port` holds 7332.
+
+`stack-release.sh --instance NAME` reads only NAME's pointer, log, store and
+backups. Its busy check sees only NAME's bus units. Its drop-in scan adds
+`mosaic-bus-NAME@*.service.d` and the shared `mosaic-bus-.service.d`. Its
+rollback set holds NAME's two unit files, their own `.d` directories and
+`$BIN/mosaic-NAME`; it never captures or restores the shared prefix
+directories (`mosaic-bus-.service.d`, `mosaic-webui-.service.d`,
+`mosaic-discord-.service.d`). The live-session guard refuses a path inside
+any named instance's config directory or `~/.mosaic-NAME`, even when that
+instance's config is unreadable.
+
+All instances run under one OS user for now. That user's processes can
+read and control every instance; a separate user per instance is row 195.
+A real second instance on this host is a Q173 window, and tunnel or Traefik
+exposure of a named Console waits for Jason after Q175 SSO.

+# Brief: a pre-push hook that refuses force-pushes, and a busy check that fails on BUSY (#426)
+
+Sage, 2026-10-20, for Mos's order mos-1078 (Vikunja P19 #426) and its go mos-1083 item 1. Owner Rocko,
+reviewer Dewey, gate owner Sage. Base: refactor at this brief's commit. Starts after row 191.
+
+## Why
+
+Morgana force-pushed a seat branch on 2026-10-20 (morgana-0016). Mos took it to Jason. Force-push is a
+Q173 exclusion, and canon says never force-push, but nothing mechanical stops one. Mos: "Done means a
+force-push from a seat worktree is refused, with a test that shows it."
+
+Earlier the same day, a busy check chained as `| tail -1 &&` passed while the slot was BUSY. The script it
+called prints BUSY or CLEAR, but it exits 0 either way.
+
+The guard has two layers:
+- (a) Gitea protection with force-push off on seat branch patterns and on refactor, next and main. ops-01
+  sets it up, through Mos (mos-1082). That part isn't this row.
+- (b) The client hook below. It can be bypassed with `--no-verify`, so (a) is the real guard and (b) is the
+  early refusal.
+
+## What ships
+
+1. `scripts/git-hooks/pre-push` (new). For each ref line git passes on stdin:
+   - It refuses when the remote sha isn't all zeros and isn't an ancestor of the local sha (`git
+     merge-base --is-ancestor`). The refusal names the ref and both shas, and the hook exits 1.
+   - A new branch passes. A delete (local sha all zeros) is refused.
+   - Any failure of the check refuses too, for example an unknown remote object. The hook fetches nothing.
+     If the remote tip isn't present locally, it refuses and says to fetch first.
+2. Install, following `scripts/queue-commit.sh --install-hook`. Either add a `--install-push-hook` there or
+   ship a small `scripts/install-git-hooks.sh`, whichever fits the existing code better. Say which in BUILD.md.
+   - The install copies the hook into the common `.git/hooks`, which every seat worktree shares.
+   - It refuses when `core.hooksPath` is set (the husky trap, 2026-10-09). It refuses when an installed
+     pre-push differs from the repository copy, unless `--force-install` is given.
+   - It never edits the installed copy in place.
+3. `scripts/slot-busy.sh` (new), the shared busy check.
+   - It prints one BUSY line per matching process, or CLEAR.
+   - It exits 0 on CLEAR, 1 on BUSY and 2 on its own error.
+   - It matches `node --test`, `gate.sh`, `mutant`, `scripts/test-*.sh` and `docker compose` command lines.
+     It skips its own process and shell snapshots.
+   - It reads `/proc/<pid>/cmdline` and the cwd link only, never file contents under another seat's
+     directory.
+   - Usage in `docs/TOOLS.md`: `bash scripts/slot-busy.sh > LOG && gate`, with `set -o pipefail` in any
+     script that pipes it. Never `| tail -1 &&`.
+
+## Tests
+
+Add them to `scripts/test-land-work.sh` or a new `scripts/test-git-guard.sh` (say which). Run against a scratch
+bare remote and a scratch clone with a worktree, never against origin:
+- A rewritten branch pushed with `--force` from a worktree is refused, and the remote ref is unchanged.
+- A `+refspec` push is refused.
+- A fast-forward push passes.
+- A new branch passes.
+- A delete is refused.
+- A remote tip that's missing locally is refused.
+- The install refuses with `core.hooksPath` set, and refuses a differing installed hook.
+- `slot-busy.sh` exits 1 with a fake `node --test` process running (a sleeping stand-in with that argv),
+  and 0 without one.
+- `slot-busy.sh | tail -1 && false` doesn't apply here. The test runs `bash scripts/slot-busy.sh >/dev/null
+  && echo ran`, and asserts it doesn't print `ran` while BUSY.
+
+Mutants, each killed:
+- drop the ancestor check
+- treat an unknown remote object as passing
+- let a delete pass
+- install over a set `core.hooksPath`
+- `slot-busy.sh` exits 0 on BUSY
+
+## Boundaries
+
+- Install the hook in the canonical checkout only after landing, as its own step with Sage. Tests use
+  scratch repositories.
+- No push to origin from a test. No change to Gitea config. That's ops-01's.
+- Don't touch `~/.mosaic`, `~/.mosaic-dev` or `~/.config/mosaic-dev`.
+
+## Gate
+
+Dewey approves the manifest. The new or changed `scripts/test-*.sh` file and every other `scripts/test-*.sh`
+are green on Sage's gate, and the mutants are killed. Done when the hook is installed in the canonical
+checkout and a scripted force-push from a seat worktree to a scratch remote is refused there. ops-01's
+server proof (a refused force-push, plus a fast-forward push and a new branch that go through) is recorded
+in Vikunja #426 by Mos.

-# Brief: Melanie's hub instance on its own host (row 195, was 190b)

-Sage, 2026-10-20. Rewritten for Mos's rulings mos-0998 and mos-1005 (Vikunja #418, #419). The first version
-put the hub under its own Linux user on dragon-lin. That form can't pass Duckworth's B7 there, because the
-factory uid's `sudo -n` succeeds on dragon-lin (Mos's recon, brain-redux
-`projects/mosaic-mvp/MELANIE-HOST-RECON.md`). Melanie's own server is ruled out too: it has 1.2 GiB RAM free
-with her two Hermes bots running, and co-tenancy would share her user and her passwordless sudo. The hub runs
-on a separate host. Which host is Jason's decision (#419): hardware outside the cluster, a cluster VM with
-factory PVE root removed, or a cluster VM with that residual accepted. This row is written so the host choice
-doesn't change it. Gitea #1693. On the 10-27 MVP path. Federation R8 (Gizmoduck's design r4, 04a6112be) needs
-this row or nothing.
+Sage, 2026-10-20, third version, for Darkwing's rewrite request and sage-1439. Gitea #1693.

-Owner Darkwing (Opus 5.5), reviewer Duckworth (author of B5 and B7), gate owner Sage. Chained on row 190
-(Q177): the hub runs under row 190's config canon. Design first. The first deliverable is
-`agents/darkwing/work/queue-190b/DESIGN.md`.
+Why it changed:
+- The first two versions put Melanie's hub on its own Linux user, then on its own host, Jason's choice under
+  #419.
+- Q181 settled the hosts: Case 1 (Jason's software factory) runs on 10.1.1.53 and Case 2 (Melanie's hub) on
+  10.1.1.54.
+- Q182 and Q183 made the hub's privilege checks a recorded acceptance. They report and don't refuse
+  (federation R8, mos-1055, mos-1063, mos-1066).
+- The Case 2 install on .54 is Gosalyn's C2-13 plus its window (#416, due by 2026-10-27). It is not this row.
+
+This row now installs Case 1 on .53. On the 10-27 MVP path (mos-0974, T1 item 1).
+
+Owner Darkwing (Opus 5.5), reviewer Duckworth, gate owner Sage. Chained on row 190's candidate (the config
+canon) and on C2-13's candidate (the install script), Q177. It reuses C2-13's `case2-install.sh`,
+`case2-precheck.sh` and `case2-unit.sh` by input, not by copy. A gap in them goes to Gosalyn as a C2-13
+change, or into this row's manifest as a named, reviewed change to those files. Design first:
+`agents/darkwing/work/queue-195/DESIGN.md`.

 ## Goal

-Melanie's hub instance (Case 2, C2-13) runs on its own host. No factory agent can read or write the hub's
-config, data root or secrets, reach its bus socket, or log in to the hub host. Her writing reaches the hub only
-through the existing git.mosaicstack.dev remotes, books repo only.
+Jason's software factory runs on 10.1.1.53 as `mosaic` under `/srv/mosaic`, in the same unit form as Case 2
+(design 9, Q181). It uses row 190's config canon and the model account the factory uses today (Q185,
+mos-1081 item 1). No new provider account.

-## Provision (blank until Jason answers #419)
+## Provision

-Who provisions the host and how is left open. Sizing from Mos (mos-0998): 4 vCPU, 8 GB RAM, 64 GB disk,
-internal network only. Each agent process measures 300 to 390 MB RSS on dragon-lin. The design takes the host
-as given: a fresh Linux host with a named admin path, reachable by the deploying seat while the row runs.
+- ops-01 runs the root steps over ssh as `localadmin`: `useradd mosaic`, `/srv/mosaic` and the unit through
+  `case2-unit.sh` from a root-owned checkout. #423 step 1 (localadmin with NOPASSWD sudo on .53 and .54) was
+  applied at 20:05:47Z (mos-1066, mos-1077), and nothing else in #423 gates this row.
+- #423 step 4 (jarvis sudo) waits until Case 1 is live on .53.
+- The host list comes from Q181. Agents may run read-only checks on .53 as `localadmin`.

 ## The design must state

-1. The deploy. Exactly what Darkwing installs on the hub host and how: the stack copy, node, the units, the
-   config dir and data root under row 190's canon (O1: `~/.config/mosaic-NAME`, and "`~` is the home of the OS
-   user that runs the instance"). Which commands run as which user on the hub host, and which need its root.
-2. Re-pin, rollback and backup on the hub host, and who runs them after the deploy key is gone.
-3. How the hub gets model access without a copy of jwoltje's `claude-session.env` or any factory credential.
-   If that needs the credentials row (T1 item 6), say so and name the interim. If it needs a new subscription
-   or a new provider account, flag it for Jason and don't pick one (mos-1008).
-4. The books repo path. Which git.mosaicstack.dev remote, which credential the hub holds for it, and that it
-   can't read or push any other repository.
-5. The admin path and the end state. The host ends with no key the factory uid can read. The design names the
-   admin path that remains (for example the hypervisor console, or a key kept off the factory uid) and who
-   holds it.
-6. The acceptance script, as code Duckworth can read. It takes Gizmoduck's list of infrastructure gate items
-   as its input (mos-1011), not a fixed set of checks. Each item names a path, its closed form and its
-   accepted form, and the script reports which form holds for each, or fails. The list covers at least:
-   - federation R8's separate-host form: the hub's bus socket, data root and config dir don't exist on the
-     factory host, the factory host mounts nothing of the hub's, and no factory agent holds a login or key
-     for the hub host
-   - B7: from the factory uid, `sudo -n`, `doas -n`, `su`, polkit, and `ssh -o BatchMode=yes` to the hub
-     host all fail
-   - the hypervisor and backup paths ops-01 measured (mos-1011: one PVE node the factory key has root on,
-     PBS on that node with unencrypted backups, a flat /16 LAN), each closed or accepted by Jason
-7. The identity provider and TLS front end (B8, mos-1008, mos-1011). Either the factory holds no credential
-   that can create users, change groups, issue tokens or impersonate in the issuer the hub trusts, or the hub
-   uses an issuer the factory can't administer. A brand, tenant or app inside the same Authentik does not
-   count as separate. The same holds for the TLS front end that serves the hub. The proof is a failed admin
-   call from every token the factory's root can read. No credential value is printed in that proof.
+1. The install as input values to C2-13's scripts: user, home, business file, roles, the human id, the
+   token slot path. Which commands run as `mosaic` through `sudo -u mosaic -H`, and which as root through
+   ops-01.
+2. Where Case 1 differs from Case 2: the factory roles in place of the library business, no library sync,
+   and any precheck item that doesn't apply, each with a reason.
+3. Model access through the existing factory account (Q185). Placing the credential on .53 is a step under
+   the Q173 secrets rule, done in the window. It is never copied by the script, and its value is never
+   printed.
+4. Re-pin, rollback and backup on .53, and who runs them.
+5. The acceptance checks, as code Duckworth can read. Each check names a path and gives it one of three
+   marks: closed, accepted under Q182 or Q183, or "not named in Q182 or Q183". An accepted path doesn't
+   fail the row. An unnamed one is reported to Mos, who takes it to Jason (the R8 N1 rule). The functional
+   checks fail the row when they fail: the unit runs as `mosaic`, the Console answers on its port on the
+   internal network only, and one tester message gets a reply.

 ## Boundaries

- Provisioning, hypervisor access and any infra or k3s change are Jason's (Q173 exclusions). Mos takes the
-  hypervisor residual (factory root on the PVE nodes, Q172) to Jason. It doesn't block this row.
- Melanie's server (`[email protected]`) is reference only, read only, under Jason's authorization in
-  mos-0995. Nothing on it changes, and her Hermes bots keep running.
- No tunnel, Traefik or other exposure outside the internal network. That waits for Jason, after Q175 SSO.
- No credential value is printed, logged or committed. Keys made for the deploy are removed at the end, and
-  the acceptance script proves it.
- The admin-call proof in point 7 and any call to the issuer or the TLS front end run only in a window Mos
-  approves, never as a test or an anonymous probe (Q175).
- Tests in the repository use scratch roots and stand-ins. The live deploy and the acceptance run on the hub
-  host are a window with a backup first (where there is state) and a STATE report after.
+- Infra and k3s changes, exposure outside the internal network, and spend stay Jason's (Q173 exclusions).
+- No change to dragon-lin's `~/.mosaic-dev`, `~/.config/mosaic-dev`, its live units or `~/.mosaic`.
+- No credential value is printed, logged or committed.
+- Tests use scratch roots and stand-ins. Nothing in a test reaches .53.
+- The run on .53 is a window with Jason's or Mos's go, a backup first where state exists, and a STATE report
+  after.

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

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

+Gitea #1735. Vikunja P19 #432.

+### Problem

+  I3 from this brief with no new briefing.
+- Reviewer: Filbert (moved from Duckworth, mos-1119 item 4).

+  install writes. `--copy ID` is the one value upgrade changes. Upgrade never edits that file except to
+  record the new copy id after a confirmed run.
+- Before A1, `copy --bundle FILE SHA` runs as the stack's user (I1), and the copy id is SHA.
+- A rehearsal runs before A2, as the stack's user: `stack-release.sh rehearse SHA BUSINESS --instance
+  NAME` against the last activation's backup. A failed rehearsal refuses with nothing stopped.
+- The root lock (sage-1524 finding, mos-1118). `--plan` skips `lock()` (`scripts/stack-release.sh:1046`,
+  `:1058`), so two root runs could both pass A1, and one could stop the units in the middle of the other.
+  `stack-upgrade.sh` takes `flock -n` on `/run/mosaic-stack/upgrade-<instance>.lock` before A1 and holds it
+  to the end of the run, rollback included. A second run refuses `upgrade-running` with exit 3.
+- A1 also refuses `open-activation` when any `AWAITING-UNITS` file exists or the `interrupted` set isn't
+  empty, before anything stops.
+- A migrating target refuses `migrate-required` unless `--migrate` is given (decision 96 stays process).
+- Root's step log is `/var/log/mosaic-stack/upgrade-<instance>.log`, `root:root` 0640, one line per step
+  (r6 :452-455).
+- Exit codes are r6's: 0 ok, 1 failed with the old stack running, 2 rollback-failed with the units
+  stopped, 3 refused with nothing changed.
+- duckworth-0055's notes on r6 apply here. Darkwing names how each one lands in the design or BUILD.md.
+- Root never parses output the stack's user wrote, beyond exit codes (r6 section 4's rule).
+
+### What ships: the host run sheet
+
+`docs/guides/host-run-sheet.md` is what ops-01 does on a fresh host before install, and once per host for
+enrollment. Every item names the precheck line that verifies it (I2). Where a precheck line is missing,
+I3 says so and Gosalyn adds it to I2.
+- The stack user and its home (`useradd`, `/srv/mosaic`), with no sudo and no supplementary group.
+- node pinned under `/opt`, with the gpg and sha256 checks.
+- claude for the factory profile, installed by root with `npm install --prefix
+  /opt/mosaic-stack/claude-<pin>`, plus managed settings with the autoupdater off. This replaces r6's
+  `/srv/mosaic/.local/bin` (D :124), per C2-13a's `--claude` rule.
+- bubblewrap, the AppArmor profile, `dpkg-statoverride`, the no-new-privs test, the pins, `hostcheck`, the
+  apt hook and the boot unit (r6). These are for any host that runs bwrap, so .54 gets them too.
+- The release transport: the bundle file, root's checkout made from it, and the stack user's own clone of
+  the bundle under its home (I1). Upgrade fetches each new bundle into both.
+- The machine-grant enrollment step, once per host (Gizmoduck's design r1 f6b6a04b6 section 3, as changed
+  by its review and mos-1120). Mos sent Q-O1 to ops-01 (mos-1121). Until that design is approved, this
+  item names the design and its open question and has no commands.
+- The credential slots Jason places, in one table per host, so he can do them in one sitting (mos-1118).
+  Each row gives the host, the absolute path, the file name, the mode, the owner, which profile needs it
+  and which precheck line checks it. Values never appear. The known slots, which the author checks against
+  the code and completes:
+  - the model credential, `<configDir>/secrets/claude-session.env` (Q185 for the factory, `ZAI_API_KEY`
+    for the library, C2-13a precheck)
+  - the library Console's proof file under `<home>/.config/mosaic-dev/secrets/` (C2-13a, library only)
+  - the library's Gitea token slot (C2-13b)
+  - the per-agent store under `<configDir>/secrets/agents/<business>/<agent>/` (row 199 D1), which Jason
+    fills only through `mosaic credentials issue` or, after #436, Approve
+  - the installer key under `<configDir>/secrets/hosts/<business>/<hostId>/installer` (mos-1120), made by
+    enrollment, not placed by hand
+- Console start: none by hand. I2 enables the Console unit (Q189).
+
+The run sheet is for ops-01 and Jason, so it uses commands and paths, not design prose.
+
+### Tests
+
+`stack-upgrade.test.mjs` runs the driver as the test's user against a scratch root, with fakes for
+`systemctl`, `flock`'s lock dir, I2's render and `sudo` (the fake execs the real I1 verbs as the test's
+user, r6's B1 pattern). r6's sequences 1-8 run through the driver, plus:
+- a second run while the first holds the lock refuses `upgrade-running` and changes nothing
+- an open `AWAITING-UNITS` refuses at A1 with no stop
+- a migrating target without `--migrate` refuses `migrate-required`
+- a failed rehearsal refuses with no stop
+- a confirmed upgrade records the new copy id in the args file, and a failed one leaves it as it was
+- the step log has one line per step, and nothing in it comes from the stack user's output
+
+Mutants: drop the flock, release the lock before rollback ends, skip A1's open-activation check, skip the
+rehearsal, accept `--migrate`'s absence, and write the args file before confirm.
+
+### Out of scope
+
+Running it on a host. The ops-01 PVE proof (install, upgrade to N+1, rollback) is a window with Mos's go.
+Q187 item 4 covers creating that one throwaway VM, which stays after the proof (mos-1119 item 1). Folding
+host prep into the command is #437.
+
+### Gate
+
+Filbert approves the manifest. The test file, the cli suite and every `scripts/test-*.sh` are green on
+Sage's gate, with the mutants killed. Target: in review 10-24, landed 10-25 (sage-1528 line 12).

+## Sign-in in the Console (Q175 phase 1, #1690)
+
+`serve --sso [--send] [--tester-port N]` makes the Console an OpenID Connect
+relying party. It reads `console.sso` from the system config (`publicOrigin`
+and one or more providers, each with its issuer, client id, a client secret
+slot, the signing algorithms it accepts and the subjects allowed in). The
+design is `agents/sage/work/q175-sso/DESIGN.md`. `--sso` can't be combined
+with `--public-host`, `--auth-header`, `--allow-user` or `--proof-*`; `--send`
+takes `--sso` in place of the preview set.
+
+- The client secret is read once at start from
+  `<config dir>/secrets/mosaic-stack/<slot>`. The start refuses a slot that is
+  a symbolic link, not a regular file, owned by another user, has any group or
+  other mode bit, or sits in the repository, the `--checkout` directory or a
+  stack copy. The value is never printed.
+- At start the Console fetches each provider's discovery document and JWKS. A
+  provider that can't be reached (a network error, a timeout, a status other
+  than 200, or a body that isn't JSON) leaves the Console up with that
+  provider's `/auth/login` at 503 and a retry every 5 s, doubling, capped at 5
+  minutes. A document that fails a check (issuer, algorithms, S256, a usable
+  key) refuses the start. `/healthz` adds `sso: { <id>: "ready" | "unreachable"
+  | "refused" }`.
+- The Console listener serves only the Host of `publicOrigin`, whatever port
+  it listens on. Any other Host, a loopback one included, gets 403 `public
+  Host required`, except `GET /healthz`, which stays open on loopback for the
+  status and release gates. The loopback operator path in the preview section
+  above does not exist under `--sso`.
+- Without a session, `/api/*` gets 401 `sign-in required` and a page load gets
+  a 303 to `/auth/login?return=<path>`. The page then shows the signed-out line
+  with a link back to sign-in. A session lasts at most 8 hours and ends after 1
+  hour without a page load or a write; a restart ends every session.
+- The page shows Sign out only under `--sso`. It posts to `/auth/logout`, which
+  ends the session and goes to the provider's end-session endpoint when it has
+  one, or to `/auth/signed-out`.
+- With `--tester-port`, the tester listener refuses any request carrying an
+  `Authorization` header, a `__Host-mosaic_session` or `__Host-mosaic_login`
+  cookie, or an `x-authentik-*` header (403 `tester listener takes no
+  sign-in`). It never serves `/auth/*`.

jason.woltje	00d4cc1f69	stack: several Mosaic Stack instances on one host (row 190, #1688 ) Squash of Darkwing's 176a6bf4b..df65a3d4c on origin/darkwing/row190-r3, the 25 manifest paths, build-r3.patch efe898c2, manifest cc0ea9e8 (Filbert approve round 3, comment 29713). Design revision 3 in agents/darkwing/work/queue-190/DESIGN.md. Gate on base `d0bbc5c1c` with the patch: 15 package suites 2664 pass 0 fail, 10 scripts/test-*.sh suites 429 pass 0 fail (plus 156 node tests in the queue suite). Refactor moved to `99a406ed3` since, a window record touching no manifest path. Mutants 20 of 20 killed (BUILD.md, round 3). No live change: the stack runs from copy `4429a104f` until a re-pin.	2026-10-20 17:49:06 -05:00
jason.woltje	99a406ed3c	sage: re-pin window `490e2771d` to `4429a104f` (row 192) record, STATE.md (sha256 a4d0a7b12f431f15), W.txt (ca9ad4a09059d3b7), S1/S2, matrices, W10 browser check and diagnosis (screenshots not committed), Mos's P3 rehearsal and flags check, W11 reads. Plan corrections after the window: NEW is 103 commits past OLD (not 106), the P3 flags note (mos-1107), and W10's line g and corrected browser checks (mos-1135, mos-1137). PRD 1.8 raise record, decision 3a6c8fb9 (mos-1140) (#1690 ; P19 386, 412)	2026-10-20 17:46:36 -05:00
jason.woltje	d0bbc5c1cb	business: 193a access level check widened to viewer (row 204, #1702 ) Squash of Morgana's 7f07da4aa..f869fd062 on origin/morgana/row193a (diff from R1's candidate `44e36fc4c`), the three manifest paths, manifest d38de8c9 (Duckworth approve, comment 29595). LEVELS gains collaborator and viewer, covers() takes a required least level, and an unknown grant level covers nothing. Gate on base `4385b9ec1` with the patch: packages and scripts/test-*.sh 2789 pass 0 fail. Refactor moved to `c9f374284` since, a SESSIONS line only. Mutants 7 of 7 killed (agents/morgana/work/queue-193a/ mutants.log on the branch). No live change.	2026-10-20 17:25:27 -05:00
