+# Row 230: C2-13a unit render and host precheck
+
+Gitea #1732. Vikunja #416 (track T2). Brief: docs/plans/2026-10-20_case2-rows.md, section "C2-13a",
+blob f6b4933f0f47 (01b40d357, sage-1562). Base: 00d4cc1f6 (row 190). Reviewer: Webby. Gate: the cli
+suite plus every scripts/test-*.sh.
+
+## What ships
+
+`scripts/case2-unit.sh` renders `[email protected]` and `mosaic-webui.service` from the two existing
+templates into the system unit directory, for the default instance only. It writes each unit through
+a temp file at mode 0644, runs `daemon-reload`, enables both units, starts the bus and then the
+Console. If the bus fails to start, the script refuses and leaves the Console unstarted. Both units
+get `WantedBy=multi-user.target`, and neither gets `After=` or `Wants=`. The script never links a unit
+file into place. A re-install refuses unless each installed unit passes the same checks, both units
+name one copy, and each equals the render apart from the copy id.
+
+`--profile library` (the default) refuses `--pm`, `--claude`, `--tester-port` and `--sso`, and needs
+the preview proxy flags plus the proof pair. `--profile factory` refuses the six proxy flags and takes
+`--pm` and `--claude`. Both refuse `--checkout` and `--board`.
+
+`scripts/case2-precheck.sh --business ID [--profile factory|library]` runs as `<user>`. It prints one
+`ok` or `REFUSED` line per check and exits 1 if any check refused. It prints variable names only,
+never values.
+
+`packages/cli/README.md:713` now says nothing creates the session env file, only the Case 2 precheck
+reads it, and the precheck prints only variable names (webby-0034 N2, webby-0035).
+
+## Deviations for review
+
+Sage accepted all six for the build (sage-1570). Webby rules on each.
+
+1. The precheck takes `--business ID`. The brief names no other way to find the business file.
+2. A run root `<dataRoot>/launches/<business>` that doesn't exist passes, with a note that the first
+   launch creates it at 0700 (session.mjs:47 and newRun). A symlink refuses, and so does an existing
+   entry that isn't a 0700 directory.
+3. The claude marker check passes when the reply holds the marker and input plus cache tokens are at
+   most 2000. **The 2000 ceiling is unmeasured.** The tests use fakes at 40 and 9000 tokens. Measuring
+   it on a real claude belongs to row 195's install run, not this row.
+4. A non-root test can't create a root-owned proof file. For the "proof not owned by the user" case,
+   the fake getent reports another uid for the user, so the user's own file reads as someone else's.
+5. The unit script refuses `%h` left in any unit, rendered or installed. A system unit expands `%h`
+   to root's home. The render replaces every `%h`, so the test edits an installed unit to reach it.
+6. With `--auth-header X-Authentik-Uid`, the allowed user must be 64 lower-case hex characters (lead
+   decision 101). The test covers both the refusal and the pass.
+
+## Tests (packages/cli/tests/case2-unit.test.mjs, 30 cases after round 2)
+
+The tests use a scratch unit directory and a scratch home, plus fake systemctl, getent, sudo, id,
+node, bwrap and claude. They never touch /etc/systemd, ~/.mosaic-dev, ~/.config/mosaic-dev or a
+live unit. Every precheck case asserts its output doesn't hold the fixture key.
+
+- Unit: the clean library render, PATH for a node outside the default list and for /usr/bin/node, the
+  systemctl order, a failed bus start, no `systemctl link`, factory `--pm` and `--claude` rendered and
+  absent, re-install to another copy, edits to an installed unit, template restrictions,
+  EnvironmentFile placement, unknown tokens, PermissionsStartOnly and `+`/`-+` Exec prefixes,
+  symlinked unit paths, bad `--node`, re-install drift, a split copy pair, bad copy ids, every library
+  and factory flag refusal, and bad `--claude`.
+- Precheck: a good host, node older than 24, more than one group, sudo succeeding, XDG_DATA_HOME,
+  HOME mismatch, a run root mode, a bad config, bwrap failing, the port floor at or below the Console
+  port, a missing Console unit, bus.tester per profile, profile-library-business, the claude check
+  (no route, replaces, appends, missing, the unit's MOSAIC_CLAUDE_BIN beating PATH), and the session
+  env file (missing, 0644, symlink, empty, emptied by a later line, quoted).
+- Bind (mos-1100): inside `binds()` plus `sandboxArgv()`, a bind on port 980 gets EACCES, and a bind
+  on a free port of 1024 or above succeeds. The test fails if the host's floor is at or below 980.
+
+## Verification
+
+Round 1 singles, run before the gate: case2-unit.test.mjs passes 28/28 with no skips, and host.test.mjs (it
+reads the cli README) passes 42/42. No test pins a hash of the README. No other test reads the two
+scripts.
+
+## Round 2 (webby-0046, sage-1589, sage-1590, sage-1591)
+
+Base: origin/refactor (rebased from 00d4cc1f6; the 15 commits between touch none of the five paths
+or the two unit templates). Branch gosalyn/c2-13a-r2.
+
+B1. The precheck now has a case for each refusal Webby named: the user missing from passwd (:77),
+a business file that is unparsable, missing or fails the schema (:137), a run root that is a symlink
+to a 0700 directory (:151), a Console ExecStart with no --port (:179), an unreadable port floor
+(:180), a claude reply without the marker (:223) and a claude reply that isn't JSON (:224). The fake
+claude gained `nomarker` and `text` kinds. The no-claude-code case and the missing-claude case share
+a PATH without `/usr/bin/claude` (`pathWithoutClaude`), so the no-claude-code case now shows a host
+with no claude passes.
+
+N1 (ruled in for this round). Before writing, `case2-unit.sh` asks `systemctl is-active` for both
+units. For each unit that was running, it prints that the unit is still on its old copy, never
+"started", and then that the bus and Console must restart together to reach the new copy. A unit
+that wasn't running gets "started ... on copy". A fresh install prints the round 1 line. The script
+still restarts nothing. The new test covers both units running and only the Console running.
+
+N4. The README line at :713 is rewrapped.
+
+Mutants, run in Sage's slot on a scratch worktree, one branch each: :77, :137, :151, :179, :180,
+:223, :224, a precheck that refuses with no claude on PATH (for the no-claude-code case), and an
+install that prints "started" for a running unit (sage-1591).
+
+## Carry items for row 195
+
+- N1's restart. Row 195 restarts the bus and Console together after a re-install over running
+  units, as the install line now asks.
+- N2. A system drop-in check like `bus-service.sh:122-145`, so a drop-in under
+  `[email protected]/` or `mosaic-webui.service.d/` can't change what the checked unit runs.
+- N3. The precheck finds claude on the shell PATH. The bus unit's `PATH=` is what a session uses
+  when `MOSAIC_CLAUDE_BIN` is unset, so the check should search that PATH.

+# Row 199 (#1697): per-agent credential store, each agent's own git identity, publish to its fork
+
+Builder: Megavolt. Brief: `docs/plans/2026-10-20_agent-credentials.md`. Design: `DESIGN.md` r6 at
+4d3007ec9, approved by Duckworth in duckworth-0027 (REVIEW-r6.md at 640011518). Authority model ruled
+by Mos in mos-1027. Branch: megavolt/row199. Reviewer: Duckworth.
+
+Status: candidate on megavolt/row199-on-190, rebased on origin/refactor 00d4cc1f6 (sage-1555). The
+full gate and the section 11 mutants ran in Sage's slot; results under "Runs".
+
+## Commits so far
+
+- 286bf598c business: agent identity, the publish grant, the project upstream with the D9c parse, store
+  credential references; git.push.remote as a hard wait.
+- a2c387dba bus: broker publish authority (checkPublish, recordPublish, publishRefused, pushCommit on
+  the raise); the D9c parse moves to `business/src/vocabulary.mjs`; pm.md and chief-of-staff.md list
+  git.push.remote among the hard waits.
+- 609dc9364 bus: the per-agent credential store in `credentials.mjs`.
+- 504336797 bus: runtime wiring, the store root and the four publish entries in the op table.
+- a18fc6cf8 tasks: request calls use `useFor` keyed from the session; the start probe keeps `use`. The
+  D5 test in `credential-store.test.mjs` pins the `use(` call sites to `credentials.mjs` (useFor's own
+  call) and `tasks/src/adapter.mjs` (the host's @sync and start probe).
+- aa740cc71 bus: the lifecycle verbs `credentials.issue`, `credentials.revoke` and `credentials.delete`
+  in `credential-verbs.mjs`, the broker branch, the runtime wiring; `organizationWriter` gets a
+  `detail` on `write` and a receipt-only `record`.
+- 0cdace415 cli: `mosaic credentials status|issue|rotate|revoke|delete`, the scripts/mosaic route, docs.
+
+## Deviations from DESIGN.md r6
+
+1. **Identity is optional on an agent.** D8 reads as identity on every agent. Today's business files
+   carry none, so identity stays optional and `publish` requires it (N10's load refusal). An agent
+   without identity commits as E7 (T6).
+2. **Revoke of a `{file}` or `{env}` reference.** Section 6 describes revoke for store references.
+   For a reference outside the store, revoke forgets the token in memory and never unlinks the file;
+   the lifecycle verb then turns the business file's reference into `store`, so a restart finds
+   nothing. The test: `credential-store.test.mjs`, "revoke of a {file} reference".
+3. **Issue order.** Issue writes the token file (tmp, fsync, rename, dir fsync), then runs the
+   caller's commit (the business file's reference becomes `store`), then sets memory. A failed commit
+   leaves the file on disk and the token out of memory, so the agent stays `not-issued` until the
+   issue is run again. The test: "a failed commit leaves the token on disk but not in memory".
+4. **The D9c parse lives in `business/src/vocabulary.mjs`, not `business.mjs`.** The broker reads
+   `forkProblem` and `forkUrl`, and `project-runtime.test.mjs` pins the broker's import closure to
+   files that import nothing. `business.mjs` wraps `parseGiteaUrl` with the loader's refusal
+   messages. The pin test names the two new imports.
+5. **`withGitea` takes the publish ticket, not a cap (D9b).** The key is the session checkPublish
+   checked with `#agent` (a run holding its claim; never a tester, reader or human), read through
+   `broker.publishSession(ticket)`. The token is usable only between checkPublish and recordPublish
+   or publishRefused. Its refusals are filed once, by publishRefused on the task's trail, and not
+   also by `refusing()`. The test: `publish.test.mjs`, "runtime: withGitea keys from the open ticket
+   only".
+6. **Role contracts.** `workflow-roles.test.mjs` requires the hard waits listed in `roles/pm.md` and
+   `roles/chief-of-staff.md` to equal GATED_ONLY. Adding git.push.remote to the vocabulary made it
+   fail, so both lists now name git.push.remote. Prose only; no hash pin reads either file. Duckworth
+   should review this hunk because `roles/` is reviewed authority.
+
+7. **Delete takes a reason.** Section 6 lists `delete AGENT` with no reason. The broker requires
+   `reason` on delete as on revoke, so every receipt that ends a credential says why.
+8. **Rotate is `credentials.issue`.** There are three bus verbs, not four. An issue over an entry the
+   bus holds is recorded as `rotate` in the receipt and the answer. The CLI's `rotate` reads the
+   status first and refuses before reading stdin when nothing is issued.
+9. **Issue covers entries the bus loaded.** The business file must already name the kind for the
+   agent, and the bus must have loaded that reference at start; otherwise `credential-unknown`. An
+   agent added after the bus started needs the restart row 165 already asks for. Row 194's human
+   `create` is where a new agent's `store` references come from.
+10. **No Console page yet.** Section 6 puts the verbs in the Console's agent page too. This branch has
+    the bus verbs and the CLI. The Console page is a separate piece (packages/webui, its `BUS_VERBS`
+    and `STATUS` pins); I raise the split with Sage before the manifest. Ruled in sage-1421: the
+    Console page is out of row 199 and becomes a follow-up row with Webby as reviewer. The manifest
+    holds bus, business, tasks, cli and seat.
+11. **The push runs in the bus child, and the git socket polls for it (D9b).** The git socket runs in
+    the host process. The broker, the runtime and the token are in the bus child that
+    `packages/cli/src/host.mjs` forks, and host ops cross that IPC one at a time with a 10 s answer
+    limit. ls-remote and the push can run longer than that, so `withGitea(ticket, fn)` can't wrap a
+    host-side git. The split: the socket runs D9 steps 3 and 4 (tip and identity under the lock,
+    `working.publish`), then op `publishPush`, which starts `publishRemote` in the bus child under
+    `withGitea` and answers `{state: 'running'}`. The socket polls op `publishResult` every 200 ms
+    until it reads `pushed` or `refused`. Fork, user, source and destination come from the ticket
+    (`broker.publishTarget`), never from the host's message. `recordPublish` also refuses `ref-moved`
+    when the pushed ref isn't the ticket's destination. A second `publishPush` on a running ticket
+    refuses `publish-busy`. The token reaches git on fd 3 only (`runGit` option `pass`), read once
+    by a one-shot credential helper that answers `get` for https on the fork's exact host and port.
+    On close, a running publish's git isn't awaited; git's own time limit ends it, and the ticket
+    goes with the process. The 10 s IPC limit stays as it is (sage-1440). The poll has a bound
+    (sage-1440): `publishDeadlineMs`, by default four times git's limit and grace (publishRemote runs
+    at most four git commands) plus 30 s. Past it the socket refuses `publish-timeout`, filed once by
+    publishRefused, and logs that the bus process's push may still reach the fork. A failure that is not a refusal is filed as `git-failed` and logged on
+    the bus's stderr by error name and code only. Tests: `seat/tests/publish.test.mjs` (11),
+    `bus/tests/publish.test.mjs` (the process ops), `cli/tests/publish-socket.test.mjs` (7, end to
+    end through the socket, the in-process runtime, the store and a TLS fake Gitea; one is the
+    publish-timeout outcome).
+12. **No harness tool for publish.** `packages/harness/src/git-tools.mjs` has push, fetch and land
+    clients. A runner tool that calls the socket's `publish` op is in packages/harness, outside the
+    manifest scope sage-1421 set. Today a publish needs a socket client; the tool is a follow-up.
+13. **The bind rule's `git.push.remote` clause has no test of its own.** D11 adds it and the
+    launcher has it. A role can publish only a push its own role made (`work-not-yours`), and
+    `recordPush` needs `git.push.working`, which already binds the socket. No role reaches the
+    clause alone, so dropping it changes no outcome today. It matters once a role can publish work
+    it didn't push. Ruled in sage-1440: keep it; its mutant goes in the section 11 list as
+    equivalent, with this reasoning, and Duckworth judges it.
+14. **A push between checkPublish and the git push refuses; it never lands a different commit.**
+    T3 says such a push "doesn't change the commit that lands". Under the hard wait it refuses:
+    `working.publish` checks the work ref's tip against the ticket's source under the lock
+    (`ref-moved`, `seat/tests/publish.test.mjs`), and `recordPublish` checks `pushCommit` again
+    (`decision-mismatch`, `bus/tests/publish.test.mjs` "r4 B4"). The fork gets only the ticket's
+    oid either way. N9's routing-commit test still applies. Ruled in sage-1440: T3's wording in
+    DESIGN.md now reads "refuses with `ref-moved` or `decision-mismatch`", and an end-to-end test
+    asserts each code mid-flight in `cli/tests/publish-socket.test.mjs`: a push after checkPublish
+    refuses `ref-moved` with no request to the fork; a push recorded while the bus process pushes
+    refuses `decision-mismatch`, filed once, and the fork holds only the ticket's oid.
+
+15. **Fix: rotate on a due gitea key (gizmoduck-0050, sage-1494).** The CLI's `ISSUED` set
+    (`packages/cli/src/credentials.mjs`) listed valid, expiring and expired, but the bus's `status()`
+    gives a gitea key past its rotate-by date `rotation-due`. So `credentials rotate` refused the one
+    case it exists for. `ISSUED` now names every state status() gives a held token. The test:
+    `cli/tests/credentials.test.mjs`, "rotate goes ahead on each held state". Its mutant (the old set)
+    fails that test and goes in the section 11 list.
+
+16. **The bus process refuses a boot config carrying `publishTls` (M26, sage-1563).** process.mjs
+    used to drop `publishTls` from the boot config before `startBroker`, and no test could see the
+    drop. The host's boot config (`packages/cli/src/config.mjs`) never carries it; it is the tests'
+    scratch CA for an in-process runtime only. A boot that carries it now refuses
+    `invalid-host-request` and the process exits 2, rather than trusting it or dropping it quietly.
+    The test: `bus/tests/publish.test.mjs`, "the bus process answers the publish ops from their own
+    lines". Every test file that reads process.mjs ran singly, green (see "Runs").
+17. **M17 is equivalent: `#authorityFor`'s pushCommit comparison is also made by `#publishFacts`.**
+    A git.push.remote raise with no recorded push refuses `no-push` (`broker.mjs` raise,
+    `pushCommit = ... ?? fail('no-push')`), so every publish decision carries a pushCommit.
+    `#publishFacts` takes `source = result.pushCommit` and refuses `decision-mismatch` when it isn't
+    `#latestPush(task_ref).commit`, the same two values `#authorityFor` compares. The check stays as
+    defense in depth, for a decision whose context lacks pushCommit, which no code path writes today.
+    Duckworth judges it, as with M27.
+
+## N9, for the routing commit (sage-1388)
+
+Today git.push.remote is a hard wait, so every publish carries a decision, and the decision's
+`pushCommit` fixes the commit. If a later commit routes git.push.remote within role, a publish has
+no decision and no `pushCommit`. `#publishFacts` then takes the commit from `#latestPush`, and the
+git socket's tip check under the lock is the only thing that holds it. That commit needs a test
+that a push between checkPublish and the git push doesn't change what lands.
+
+## R1, the backup set
+
+Checked at 504336797. Row 185's `backup_store` (`scripts/stack-release.sh:372-392`) copies only
+`<dataRoot>/bus/bus.sqlite`, plus its sums, modes, listing and stamps, into
+`<dataRoot>/backups/stack/<activation>/`. Nothing under `<configDir>` is copied, so
+`<configDir>/secrets/agents` isn't in the backup set. `rehearse` copies the live business file
+through `R_BUSINESS_JS` (`:1268-1288`). Its `swap` replaces every credential reference, a `store`
+one included, with a placeholder file in the rehearsal's own dir. The guard then refuses
+`credential-ref-live` unless every reference is such a placeholder (`:1329-1337`), so a rehearsal
+never reads a store token. A backup tool outside this repository that copies `<configDir>` would
+copy tokens. That is R1's open half, and it is Jason's to check on each VM.
+
+## T1 limit
+
+A wrong owner on a store dir or file can't be set up without root, so T1 covers modes, symlinks and
+dirs. The owner check (`st.uid !== process.getuid()`) is in `privateDir` and `#read`, and is untested.

+# Row 199 design: a credential store per agent, own git identity, pushes to a remote
+
+Megavolt, 2026-10-20. Gitea #1697, MVP T1 item 6. Brief: `docs/plans/2026-10-20_agent-credentials.md`.
+Reviewer Duckworth. Mos rules on the authority model (section 9) before any code. Base: refactor at 992650232.
+No credential value was read to write this. Evidence is code and docs only.

+
+r5 takes webby-0011 N1 (row 194 review, through honker-0009): the host checks at each push that the
+remote's owner is the agent's own Gitea user. r4 named one `remote` per project, which can't be a fork per
+agent (O1) once two agents publish the same project. So `projects.<p>.remote` now names the upstream
+repository, and the host builds each agent's fork URL from it (D9 step 2, D10, T3). It also fixes a conflict
+found while building: D8 made `identity` required for every agent whose definition declares `gitea`, while D9
+step 2 says today's files load unchanged. Coder declares `gitea`, so r5 makes `identity` optional and
+`publish` require it (D8).
+
+r6 answers duckworth-0026 (REVIEW-r5.md at 3cb6888e1), with Mos's acceptance (mos-1043). B5: the derived URL
+has one name, `fork`, and D9a's `ls-remote`, step 5's push, the helper's host match, `checkPublish`'s result
+and step 6's event all use it (D9, D9a, D9b, T3). B6: the URL parse is written down (D9c) and tested (T3).

+## 0. Terms
+
+- **Stack instance**: one Mosaic Stack deployment (row 190). It has one OS user, one config dir
+  `~/.config/mosaic-NAME` (here `<configDir>`), one data root and one bus. Case 1 and Case 2 are two stack
+  instances on two VMs (DECISIONS Q180).
+- **Agent**: a role instance in a business file (`roles.<agent>`). Today's code calls it "instance". This
+  design says agent.
+- **Kind**: a credential type: `gitea`, `vikunja`, `model`.
+- **Host**: the bus process and its git socket, running as the stack instance's OS user, outside any sandbox.
+
+## 1. What exists (measured at 992650232)
+
+| Code | Fact | Where |
+|---|---|---|
+| E1 | The business file references credentials per agent: `roles.<agent>.credentials.<kind> = {file or env, rotateBy or expires}`. The kinds an agent may hold are the ones its role definition lists | `business/src/business.mjs:89-111`, `credentials.mjs:18-38`, `role.mjs:105-118` |
+| E2 | The bus reads each token once at start (O_NOFOLLOW, own uid, 0600, at most 16 KiB, outside the repos and data root) into a private map keyed `<business>/<agent>:<kind>` | `bus/src/credentials.mjs:18-89`, `bus/src/runtime.mjs:78-89` |
+| E3 | Only Vikunja uses a token: `credentials.use("<business>/<agent>", "vikunja", ...)`. Gitea tokens are loaded and never used. `assertClean` refuses any event that contains a token | `tasks/src/adapter.mjs:70`, `runtime.mjs:134`, `broker.mjs:560` |
+| E4 | Agents run in bwrap as the bus's own uid. `~/.config`, `~/.mosaic` and `~/.ssh` are not bound. The git socket is bound only for `git.push.working`, `review.verdict` or a landing | `seat/src/sandbox.mjs:21-30, 104-124`, `cli/src/launcher.mjs:401` |
+| E5 | A session proves who it is with a 64-hex cap the broker mints and maps to a frozen session record. The git socket resolves the cap to (business, role) before anything else | `broker.mjs:280, 379-383`, `packages/cli/src/git-socket.mjs:398-407` |
+| E6 | The model credential is one env file per host (`EnvironmentFile=-%h/.config/mosaic-dev/secrets/claude-session.env`). `ENV_ALLOW` passes it into every sandbox, so every agent holds the same model token | `cli/systemd/mosaic-bus.service.in:24`, `seat/src/session.mjs:83-94` |
+| E7 | Commits in a session's clone use `<agent>@<business>.mosaic.invalid`. Landed squashes use "Mosaic bus host" | `sandbox.mjs:151-157`, `working.mjs:280-281` |
+| E8 | No code pushes to a remote. The git socket pushes bundles into a local bare working repo with no remote and no credential | `working.mjs:1-14, 198-238` |
+| E9 | Adding or changing an agent refuses a definition that declares credentials (`organization-credentials-out-of-scope`). Binding them is a hand edit. Row 194's design keeps that refusal for create and hire "until the credentials row" | `business/src/instance-settings.mjs:20-29`, row 194 DESIGN.md D1 |
+| E10 | The development repository's helper pushes as one identity from one JSON file | `scripts/git-credential-mosaic.mjs` |
+
+So per-agent references and a host-only reader already exist for two kinds. What's missing: a fixed place for
+the files, an agent identity, any remote push, lifecycle verbs, and a model credential that agents don't
+share.
+
+## 2. The store (brief item 1)
+
+D1. **Layout.** Each stack instance keeps its agents' secrets under its own config dir:
+
+```
+<configDir>/secrets/agents/                       0700, owner = the stack instance's OS user
+<configDir>/secrets/agents/<business>/<agent>/    0700
+<configDir>/secrets/agents/<business>/<agent>/<kind>   0600, the token only, one line
+```
+
+This is row 190's secrets root (`<configDir>/secrets/...`, as Q175's slot uses). The token file keeps E2's
+format, so the bus reader doesn't change. Nothing in a token file is a name, an email or a URL. Those are not
+secret and go in the business file (D6), where review sees them.
+
+D2. **The business file reference.** A new reference form, `{"store": true, "rotateBy" | "expires": DATE}`,
+means "the file at the layout path for this business, agent and kind". The path is derived, never written,
+so an agent's entry can't name another agent's file. The old `{file}` and `{env}` forms stay valid for
+migration (section 7). A `{file}` reference that points inside `<configDir>/secrets/agents/` but not at its
+own agent's path refuses `credential-not-yours` when the business file loads.
+
+D3. **Read path.** Unchanged in shape: the bus reads every entry once at start (E2) and on a store change
+(section 6), and holds the values in memory. No sandbox binds `<configDir>` (E4 already holds). No token goes
+into a sandbox for `gitea` or `vikunja`. The agent asks the bus to act, and the bus uses the token.
+
+D3a. **A `store` reference with no file.** ENOENT on a `store` path loads as an absent entry. `status` shows
+`not-issued`, and `useFor` refuses `credential-unavailable`. The bus still starts. This is the state after a
+create without `issue` (D13) and after `revoke` (section 6). Every other defect still refuses start: wrong
+owner or mode on the file or a dir, a symlink, a non-regular file, bad format, a missing or wrong-mode
+`secrets/agents/` dir. `{file}` and `{env}` keep E2's behavior, where a missing file refuses start.
+
+## 3. The "RLS equivalent" (brief item 1)
+
+Three layers. Each one is enforced by code or the OS, not by prose.
+
+D4. **OS, between stack instances.** Files are 0600 and dirs 0700, owned by the stack instance's own OS user.
+Case 1's user can't read Case 2's store (Q180: each instance under its own user without sudo). The bus refuses
+to start when any file or dir under `secrets/agents/` has the wrong owner or mode (`credential-file`, as E2
+does for files today, extended to the dirs).
+
+D5. **Bus, between agents of one stack instance.** The principal for every credential use comes only from the
+verified cap (E5). The agent-facing API is `credentials.useFor(session, kind, op)`: `session` is the broker's
+frozen record, and the key is built from `session.business` and `session.role`. It has no agent argument, so
+there is nothing in a request to point at another agent. The existing `use(name, kind, op)` stays for the
+host's own `@sync` entry and is not reachable from a request. The tasks adapter's per-role calls (`ctx.as`,
+`verbs.mjs:126`) move to `useFor`. Any request field that names an agent other than the caller (`as`,
+`agent`, `instance`, `role` on a credential path) is refused `credential-not-yours` and recorded through
+`broker.refuse()` as `action.refused`, with the caller's cap and the task ref. A build test greps every
+`credentials.use(` call site and fails on a new one outside the allowlist.
+
+D6. **What stays open.** A process of the same OS user outside the sandbox can read every agent's file. That
+is the same limit as the human proof (P19 333). Q180's per-user VMs move the boundary to "one stack instance
+per OS user". Agents of one instance are kept apart by the sandbox and D5, not by the OS.
+
+## 4. Kinds (brief item 2)
+
+| Kind | 10-27 | Use |
+|---|---|---|
+| `gitea` | yes | Git push to a granted remote (section 5). Gitea API verbs (issues, pull requests) wait. The factory's review flow runs in the working repo today, and no 10-27 case needs an agent to open a pull request |
+| `vikunja` | yes, exists | Moves to `store` references and `useFor`. No behavior change |
+| `model` | per stack instance only | See D7 |
+
+D7. **Model provider.** A model token has to sit inside the sandbox today, because the harness calls the
+provider itself (E6). Per-agent model tokens need a proxy that holds the real token and gives each run its own
+short-lived one, which is the CLIProxyAPI line in TARGET.md. That waits for its own row. For 10-27 the model
+credential is per stack instance: row 190's `<configDir>/secrets/claude-session.env`, owned by that
+instance's OS user. It is never a copy of jwoltje's file. Jason signs in on each VM user himself (A6). Whether
+Case 1 and Case 2 run on Jason's existing subscription or need a new account is Jason's call (Q-J1). This row
+doesn't pick. A pi model credential also waits for P19 #383.
+
+## 5. Git identity and push (brief item 3)
+
+D8. **Identity.** A new business-file key, `roles.<agent>.identity = {name, email, gitea: {url, user}}`. It is
+optional, because today's business files with a `gitea` agent (coder) must load unchanged. `publish` (D9
+step 2) requires it, and requires that the definition declare `gitea`. A business file with a `publish`
+grant on an agent that lacks either refuses at load, and the error names `roles.<agent>.publish` and says
+"needs identity and a gitea definition" (N10). Load is the only place this is checked: a business file that
+fails it never reaches the bus. The sandbox sets `GIT_AUTHOR_*` and `GIT_COMMITTER_*` from
+it in place of E7's invalid domain. The email is the one Jason gives the agent's Gitea user, so Gitea links the
+commits to that user. Agents without `gitea` keep E7.
+
+D9. **Push to a remote: a new git socket op, `publish`.** No new socket, no bundle, and no token in the sandbox.
+
+```
+publish {"cap", "op": "publish", "task_ref", "project", "branch", "decision"}
+  -> {"ok": true, "result": {"fork", "ref", "commit", "previous"}} or a refusal
+```
+
+The host checks, in order, and each refusal goes through `broker.refuse()`:
+
+1. Identity from the cap (E5), then the broker's `#checkAuthority(s, "git.push.remote", {decision, target:
+   task_ref})`, as `checkLand` does for a merge (`broker.mjs:907-913`). `git.push.remote` is a new action in
+   ACTIONS and is not in ROUTED (REQ-WAIT-3, `packages/business/src/vocabulary.mjs:52-58`,
+   `broker.mjs:42-69`), so it is a hard wait and classifies `gated` for every role. Every publish therefore
+   needs a decision the human resolved for this task ref. A decision is spent once (`decision-consumed`).
+
+   **The decision binds one commit.** `#authorityFor` binds action, role, thread and target only
+   (`broker.mjs:769-798`), so the commit needs its own carrier. The raise records it the same way it records
+   `holderRun` for `role.revoke` (`broker.mjs:1733`). When the action is `git.push.remote`, the
+   `decision.raise` event body gets `pushCommit`. That is the commit of `#latestPush(business, target)` at
+   raise time, read by the broker and never taken from the agent. A raise with no recorded push for the task
+   refuses `no-push`. The decision's question shown to the human ends with that commit. `#authorityFor` then
+   refuses `decision-mismatch` when `context.pushCommit` differs from the commit of `#latestPush` now, which
+   is the same check `holderRun` gets at `broker.mjs:796`. So the sequence approve at A, push B, publish B
+   refuses.
+   No role definition grants the action yet. When Jason's PRD version routes it (Sage, Vikunja #420), a
+   reviewed commit adds it to both ROUTED lists and to coder's `withinRole`. From then on a coder publishes
+   without a decision, and `decision` is optional for a within-role class only.
+2. The project is in the agent's grant, `roles.<agent>.publish: [project]`, and the business file names the
+   project's upstream repository, `projects.<project>.remote: "https://HOST/OWNER/REPO"`
+   (`remote-not-granted`). Both URLs pass D9c's parse at load. The upstream's host and port equal
+   `identity.gitea.url`'s (`remote-host-mismatch`). The host never contacts that URL. It builds the agent's
+   fork, `fork = https://HOST[:PORT]/<gitea.user>/REPO`, from the upstream's origin and repository name and
+   the agent's own `gitea.user`. `fork` is the only URL the rest of `publish` uses: D9a's `ls-remote`, step
+   5's push, the helper's host match, `checkPublish`'s result and step 6's event. So the owner of the
+   repository that receives a push is the agent's own Gitea user on every push, by construction, and the
+   agent can't name it (webby-0011 N1). D9c is what makes "by construction" hold. Gitea's refusal of a
+   push to a repository the user doesn't own or collaborate on is the second layer. An upstream whose owner
+   equals the agent's `gitea.user`, compared without case, refuses `remote-not-fork`, at load and at push. `remote` is a new key
+   beside `root` and `repo` (`business.mjs:186`), and `identity` and `publish` are new keys on a role entry
+   (`business.mjs:89`). All three are optional, so today's business files load unchanged.
+3. The source is one commit, `C = context.pushCommit`. It is checked three ways, so all three are equal:
+   the decision's commit, the commit of `#latestPush`, and the work ref's tip in the working repo,
+   `work/vikunja-<project>-<task>` (`working.mjs:110-114`). The tip is read under the repository's lock, and
+   if they differ the push refuses `ref-moved`. The work ref is per task, not per agent. Two checks make it the
+   caller's: `#latestPush` was recorded by the caller's role (`work-not-yours`), and step 4. The destination is always `refs/heads/<gitea.user>/<branch>`, built by the host.
+   `validBranch(branch)` holds (`invalid-request`). The agent never names the destination ref.
+4. Every commit in `main..<work ref>` has author and committer email equal to `identity.email`
+   (`identity-mismatch`).
+5. The push runs through `credentials.useFor(session, "gitea", ...)`: `git push <fork> <C>:<dst>`, by oid,
+   with no `+` and no `--force`. It never pushes by ref name, so a push to the working repo after
+   `checkPublish` can't change what goes out (`non-fast-forward` from git stays a refusal). Git runs with E8's SAFE flags
+   (`working.mjs:92-98`), which set `protocol.allow=never`. `publish` adds exactly two flags,
+   `protocol.https.allow=always` and `http.followRedirects=false`, plus `GIT_TERMINAL_PROMPT=0` and no global
+   or system config. The token reaches git through a one-shot credential helper that reads it from an
+   inherited pipe, never through argv, env, the URL or a file. Seat `gitEnv` (`checkout.mjs:79-89`) takes only
+   PATH from the host and sets the rest itself, so no proxy or `GIT_SSL_*` variable reaches git. `publish` takes a `tls` parameter that
+   defaults to `[]`, the same way `push` takes `fsck = FSCK` (`working.mjs:100`). Tests pass
+   `["-c", "http.sslCAInfo=<scratch CA>"]`. The host never sets it, and nothing in config or env reaches it. The helper answers `get` only when `protocol`
+   is `https` and `host`, port included, equals `fork`'s. It writes nothing for any other `get` and for
+   `store` and `erase`. `assertClean` checks git's output, so a fork that echoes the token gets
+   `credential-leak`.
+6. The bus records `action.allowed` for `git.push.remote` with fork, ref and commit.
+
+D9a. **The agent's fork must share root's history.** A push sends every object the fork lacks. The working
+repo's `main` is the project root's history (`working.mjs`, seed), so a fork that doesn't share it would
+receive all of root, landing squashes included. The check runs on `fork`, never on the upstream: a related
+upstream says nothing about what the agent's `<user>/REPO` holds.
+`publish` runs `seed` first (`working.mjs:164-176`), under the repository's lock as `push` does, so `main`
+catches up with root before the check below. That means a fork also receives any landed root commits that
+upstream doesn't have yet, because they sit under the agent's work. That is expected: the agent's branch is
+built on them.
+Before the push, the host runs `git ls-remote --symref <fork> HEAD` (same flags and helper). It refuses
+`remote-unrelated` when the fork is empty or when that tip isn't a commit the working repo already has and an
+ancestor of `main`. When `ls-remote` exits non-zero, for a fork that doesn't exist, a refused token or a
+network failure, `publish` refuses `fork-unavailable` and the push doesn't run (N11). Git's stderr isn't
+parsed to tell those apart and isn't returned, since it can carry the URL. Only `ls-remote` crosses the
+network for this, so nothing is fetched from the fork. If the fork has moved past root, the refusal stands
+until root catches up. That is a human pull into root, not an agent's.
+
+D9c. **The URL parse (B6).** `projects.<p>.remote` and `identity.gitea.url` are parsed with `new URL()` at load,
+and the business file refuses to load unless all of these hold:
+
+- The scheme is `https:`. There is no username, password, query or fragment.
+- The string equals its own normalized form: for the upstream, `url.origin + url.pathname`; for
+  `gitea.url`, `url.origin + "/"` or `url.origin`. So a dot segment (`/<user>/../OWNER/REPO`), a
+  percent-encoded dot, an upper-case host, an explicit `:443`, a backslash, userinfo, a query and a fragment
+  each refuse, because `new URL()` would change them (checked with node: each differs from its normalized
+  form). A trailing slash survives normalization and is refused by the two-segment rule below. The checks below run on that path, so the owner that is checked is
+  the owner that is used.
+- The upstream's path is exactly `/OWNER/REPO`: two non-empty segments, no more and no fewer. One trailing `.git` on
+  REPO is allowed and stripped. `fork` is built from the stripped REPO.
+- `OWNER`, `REPO` and `gitea.user` each match Gitea's name rule, `^[A-Za-z0-9_.-]{1,100}$` and not `.` or
+  `..`. REPO after stripping must still match.
+- `gitea.url`'s path is `/`. A Gitea served under a sub-path isn't supported by this row and refuses at load.
+- Host and port are compared after `new URL()` normalized them, and an omitted port counts as 443 on both
+  sides.
+- Gitea compares user and repository names without case (`lower_name`), so `remote-not-fork` compares the
+  upstream's OWNER with `gitea.user` without case. An upstream owned by `Coder` and a `gitea.user` of `coder`
+  would otherwise build a "fork" that is the upstream itself.
+
+D9b. **How `publish` reaches the broker and the store.** The git socket runs in the bus process
+(`cli.mjs:504-506`) and reaches the broker only through the host's op table (`bus/src/runtime.mjs:222-246`).
+`publish` adds three entries there, each wrapped in `refusing()`:
+
+- `checkPublish(cap, args)`: steps 1 to 3, including the decision check. It returns `{ticket, fork, user,
+  email, source}` and no token. The ticket holds the session and the decision until `recordPublish`, the
+  same way `checkLand` holds a landing.
+- `withGitea(cap, fn)`: `credentials.useFor(broker.session(cap), "gitea", fn)`. `fn` gets the token and runs
+  step 5. The token never leaves that call.
+- `recordPublish(ticket, result)`: step 6, and it spends the decision.
+
+The op table gets no entry that returns a token.
+
+D10. **Which refs.** Our side: only `refs/heads/<gitea.user>/*`, set by the host (D9 step 3). The default
+branch and other agents' prefixes can't be named. Gitea side, two options (Q-M1):
+
+- **O1. A fork per agent. Ruled by Mos (mos-1027).** The agent's Gitea user has read on the upstream repo and owns a fork
+  named like it. The host derives the fork's URL from the upstream and the agent's user (D9 step 2).
+  Its token can write only repos the user owns or collaborates on, so Gitea itself stops any push to upstream
+  or to another agent's fork. No branch rules are needed per agent, so none can drift. The cost: work reaches
+  upstream as a pull request from the fork, opened by a human or a later API verb.
+- **O2. One shared repo. Not chosen.** The agent is a Write collaborator. Upstream's default and release branches get
+  branch protection with no agent on the push list, plus a rule `<user>/*` per agent. Gitea doesn't stop agent
+  A from creating an unprotected name outside `A/*` unless a catch-all rule outranks the per-agent ones. That
+  depends on Gitea's rule priority, which I haven't verified on our version (probe P1). Every hire adds a rule.
+
+Token scopes for either: `write:repository` and `read:user`, nothing else, per vocabulary.mjs rules (no
+`all`, no admin).
+
+D11. **The host git socket.** `publish` is added to the socket. `push`, `fetch` and `land` don't change. The
+socket's bind rule (E4) adds `git.push.remote`. The working repo stays credential-free and remote-free. The
+`fork` URL is passed per call and never written into its config. A landing still squashes into the project
+root as "Mosaic bus host". Landings don't push anywhere.
+
+## 6. Lifecycle (brief item 4)
+
+All verbs are on the bus, in the CLI (`mosaic credentials ...`) and in the Console's agent page. Every verb is
+human-only. Under Q173 the tester may run `status` and `revoke` on the dev stack instance. `issue` and
+`rotate` stay with Jason, because the tester is an agent and the token would pass through its session
+(duckworth N1). Each one appends to the organization
+writer's `changes.jsonl` (actor, agent, kind, verb, date; never a value). No schema migration, no new event
+kind. A refusal uses `action.refused`.
+
+| Verb | What it does |
+|---|---|
+| `issue AGENT KIND --rotate-by DATE` (gitea) or `--expires DATE` (vikunja) | Reads the token on stdin (never argv), checks E2's format, writes `<kind>.tmp` 0600, fsyncs, renames over `<kind>`, and sets the business file reference to `{"store": true, date}`. The bus reloads that one entry, with no restart |
+| `rotate` | Same as `issue` over an existing entry. The old value is gone from disk and memory when the call returns. Jason then deletes the old token in Gitea (A5) |
+| `revoke AGENT [KIND] --reason` | Drops the entry from the bus's memory first, then unlinks the file. A use in flight finishes. Every later use refuses `credential-unavailable` |
+| `delete AGENT` | `revoke` for every kind, then removes the agent's dir. Refused while the agent has a running claim |
+| `status [AGENT]` | Kind, date and state per entry (E3's `status()`), no values |
+
+D12. **"Stops working at once."** On our side this holds without a timing window. A fired agent never holds a
+`gitea` or `vikunja` token (D3), so revoking means the bus no longer has it. On the Gitea and Vikunja side the
+token still exists until Jason deletes it (A5). The status line for a revoked entry says so until Jason
+confirms. The model token is the exception: it sits in the running sandbox (D7), so a fired agent's runs must
+end. Row 194's fire ends them.
+
+D13. **What row 194 calls.**
+
+- `credentials.issue` is never called by the chief. Row 194's hire stays uncredentialed (its D1).
+- A human `create` of a credentialed definition: row 194 lifts E9's refusal for the human path only. The agent
+  is created with `store` references and no files. `launch` refuses `credential-unavailable` until Jason runs
+  `issue`.
+- `fire` and `delete`: row 194 calls `credentials.revoke(business, agent, {reason, actor})` before it changes
+  the business file. A failed revoke stops the fire (`credential-revoke-failed`), so an agent can't be fired
+  with its credentials still live on our side.
+- `regenerate`: no credential change.
+
+## 7. Who does what (brief item 5)
+
+Agents never mint accounts or tokens. Jason's steps, per agent that needs `gitea`:
+
+- A1. Create the Gitea user: Site Administration, User Accounts, Create User Account. The name is the agent's
+  `gitea.user`. The email is the agent's `identity.email`.
+- A2. Create its token: sign in as that user, Settings, Applications, Generate New Token, scopes
+  `write:repository` and `read:user`, nothing else.
+- A3. Create the fork of each granted repo as that user (O1). Gitea's push-to-create
+  (`ENABLE_PUSH_CREATE_USER`, `ENABLE_PUSH_CREATE_ORG`) stays off, so a push to a missing `<user>/REPO`
+  fails rather than creating a plain repository (N11). `publish` refuses `fork-unavailable` before that.
+- A4. On the stack instance's VM, as its OS user: `mosaic credentials issue AGENT gitea --rotate-by DATE`, with
+  the token pasted into stdin.
+- A5. On fire or rotate: delete the token in Gitea (Settings, Applications), or disable the user.
+- A6. Model: sign in to the provider on each VM user to write `<configDir>/secrets/claude-session.env`.
+
+Vikunja bot accounts and tokens are already Jason's (tracker bots). Only A4 changes for them.
+
+## 8. Migration (brief item 6)
+
+- M1. Existing `{file}` and `{env}` references keep working. A business moves one agent at a time with
+  `issue`, which rewrites that agent's reference to `store`.
+- M2. Nothing here touches the dev repository's helper, its `.git/config`, `~/.mosaic` or `~/.mosaic-dev`.
+  Dev seats (jarvis, seat tokens) keep pushing as today. The mos-0981 rule ends only when Mos says so.
+- M3. The live dev stack instance needs no change at re-pin: no reference uses `store` until someone issues
+  one.
+
+## 9. Questions
+
+Mos ruled on the authority model in mos-1027 (2026-10-20T19:27Z):
+
+- Q-M1. O1, one fork per agent.
+- Q-M2. `git.push.remote` and its bounds in D9 to D11 are approved. It lands as a hard wait: out of ROUTED,
+  and no role grants it within-role (D9 step 1). Sage puts its routing in the PRD version draft going to
+  Jason with `role.hire` and `role.fire` (Vikunja #420). After his approval, a reviewed commit routes it and
+  grants it to coder.
+- Q-M3. Issue, rotate and delete are human-only, and the chief gets none of them. Under Q173 the dev
+  instance's tester gets `status` and `revoke` only.
+- Q-M4. The model credential stays per stack instance for 10-27. Per-agent model tokens wait for a proxy
+  row.
+
+Open for Jason. Mos takes these to him one at a time:
+
+- Q-J1. The model account for Case 1 and Case 2: existing subscription or a new account.
+- Q-J2. Gitea users and tokens for the agents that need them (A1 to A3).
+
+## 10. What this closes (brief item 7)
+
+- G11: closes the store (D1 to D6) and lifecycle (section 6) for `gitea` and `vikunja`. Still open: per-agent
+  model credentials (D7), and the same-uid limit inside one stack instance (D6).
+- G13: closes "own credentials for git" (D8 to D10). Still open: Gitea API verbs (section 4).
+- C2.5 (git remote): Case 2's books repo can use `publish` once its project names a remote.
+
+## 11. Tests and mutants
+
+All tests use scratch roots, fake tokens and a fake Gitea: `git http-backend` behind a node http server on
+127.0.0.1 that checks basic auth against a fake token and records each ref update. No request leaves the host.
+
+- T1. Layout: wrong mode or owner on a dir or file refuses start. A `{file}` reference into another agent's
+  path refuses `credential-not-yours`. A bus restart after a create without `issue` starts, and the agent's
+  status is `not-issued`. A missing `{file}` still refuses start.
+- T2. `useFor` keys from the cap only. A request naming another agent is refused and leaves one
+  `action.refused`.
+- T3. The fake Gitea serves https on 127.0.0.1 with a cert from a scratch CA made by the test. It reaches git
+  only through the `tls` parameter (D9 step 5). Each refusal test that should reach the network asserts that
+  the first port received the request, so no test passes because git refused http first. `publish`: the
+  happy path lands `refs/heads/<user>/<branch>` on the agent's fork in the fake, which shares root's history, at
+  exactly the decision's commit. Refusals for each step in D9, one test each, including `work-not-yours`. Until routing, a publish with
+  no decision refuses, one with a decision for another task or commit refuses, and a second publish on a
+  spent decision refuses `decision-consumed`. Approve while the latest push is A, push B, publish: refuses
+  `decision-mismatch`, and the fork receives nothing. A push to the working repo between `checkPublish` and
+  the git push refuses with `ref-moved` or `decision-mismatch` (sage-1440, BUILD.md deviation 14). A raise with no recorded push refuses `no-push`. A test pins that `git.push.remote` is in neither ROUTED list
+  and that no `roles/*.json` grants it. A force-push attempt is
+  refused by git's non-fast-forward. A fake fork that answers 302 to a second 127.0.0.1 port: the push
+  fails, and the second port receives no request with an Authorization header. A remote on the right host
+  and a different port is refused at step 2. Two agents granted one project each land on their own fork:
+  agent A's push reaches `/<A's user>/REPO` only and B's reaches `/<B's user>/REPO` only, and the fake's
+  upstream repository receives nothing. An upstream owned by the agent's own user refuses `remote-not-fork`,
+  and so does one whose owner differs from `gitea.user` only in case. With an upstream that shares root's
+  history, a first publish to an empty fork and to an unrelated fork each refuse `remote-unrelated`, and
+  neither fork nor upstream receives objects. A fork that doesn't exist refuses `fork-unavailable`, and the
+  fake records no push. `ls-remote` and the push each reach the fork's path only (the fake records every
+  path). Load refusals (D9c), one test each: a dot segment, an extra path segment, a missing segment,
+  a trailing slash, userinfo, a query, a fragment, an explicit `:443`, a name outside Gitea's rule, and a `gitea.url` with a
+  sub-path. A `.git` suffix loads and builds the fork without it. A `publish` grant on an agent without
+  `identity`, and on one whose definition lacks `gitea`, each refuse at load with the N10 message.
+- T4. Token handoff: the token never appears in argv, env, the fork URL, the working repo config,
+  `changes.jsonl`, events or logs (scan every file under the scratch roots).
+- T5. Lifecycle: issue, rotate, revoke and delete, each live with no restart. After revoke, `publish` and the
+  Vikunja path refuse `credential-unavailable`, and so they do after a bus restart that follows the revoke.
+  The tester can run `status` and `revoke`, and `issue` and `rotate` refuse it.
+- T6. Default: an agent without `identity` commits as E7. Existing `{file}` references load unchanged.
+
+Mutants to kill: drop the cap-derived key in `useFor`, let the request name the destination ref, add `+` to
+the refspec, skip the identity check, put the token in the URL, revoke file before memory, skip the dir mode
+check, allow a `{file}` reference into another agent's dir, make ENOENT on a `store` path fatal again, make
+ENOENT on a `{file}` path silent, a helper that answers any host, drop `http.followRedirects=false`, drop the
+`work-not-yours` check, drop the `remote-unrelated` check, add `git.push.remote` to ROUTED, skip the spent
+check on the decision, drop the `pushCommit` comparison in `#authorityFor`, push by ref name in place of the
+oid, push to the upstream URL in place of the derived fork, run `ls-remote` against the upstream in place of
+the fork, take the fork's owner from anywhere but the agent's `gitea.user`, compare the owner with case, run the
+D9c checks on the raw path in place of the normalized one, read a failed `ls-remote` as empty, skip the tip
+check under the lock, and pass a CA flag in production.
+
+## 12. Risks
+
+- R1. Backups: if a backup tool copies `<configDir>`, it copies tokens. The build checks row 185's backup set
+  and says what it includes.
+- R2. Withdrawn. O1 was ruled, so probe P1 isn't needed.
+- R3. Outbound HTTPS from the bus host to Gitea is new network reach for the host process. On the VMs this is
+  Jason's network to confirm.

+# Row 237: one decision publishes once (#1743)
+
+Megavolt, 2026-10-21 (from `date -u`). Brief: `docs/plans/2026-10-20_agent-credentials.md`
+§ "row 199 follow-up N1", blob dca67d310e1b. Source: Duckworth's row 199 round 1 note N1
+(duckworth-0068). Base: `cb5fdb064` (row 199's landing). Reviewer Duckworth, gate owner Sage.
+
+## The defect
+
+`checkPublish` opens a ticket after checking the decision is unspent. The decision is spent only at
+`recordPublish`, which runs after the bus process has pushed. Two `checkPublish` calls on one decision
+therefore both get tickets, and both push. With different branches, the commit lands on two fork refs:
+`refs/heads/<user>/feat` and `refs/heads/<user>/other`. The second `recordPublish` then refuses
+`decision-consumed`, but by then its push has already reached the fork.
+
+## The fix, and why this option
+
+`checkPublish` refuses `publish-busy` when an open ticket in `#publishes` holds the same business and
+decision (`packages/bus/src/broker.mjs:1038-1040`). It runs after the authority and fact checks, so a
+spent decision still refuses `decision-consumed` first.
+
+The brief's other option, rechecking `#spent` in `publishTarget`, doesn't close the race. Both tickets
+reach `publishTarget` before either push ends, and nothing is spent until `recordPublish`. So both
+rechecks pass and both pushes run. The only state that exists while the first push runs is the open
+ticket, so the check reads that.
+
+A refusal (`publishRefused`) drops the ticket and leaves the decision unspent, so a retry on the same
+decision gets a new ticket. That is row 199's behaviour, unchanged. A within-role publish has no
+decision and isn't affected.
+
+## Tests
+
+- `packages/bus/tests/publish.test.mjs:186`. A second ticket refuses `publish-busy`, on the same branch
+  and on another. After `publishRefused` the retry gets a ticket and a third refuses busy. After
+  `recordPublish` there is one `action.allowed` for git.push.remote and the next call refuses
+  `decision-consumed`. Another agent's decision on the same task isn't held.
+- `packages/cli/tests/publish-socket.test.mjs:269`. End to end through the git socket, the bus runtime
+  and the TLS fake Gitea. While the first publish holds its ticket, a second publish on the same
+  decision to branch `other` gets `publish-busy`. The fake Gitea gets exactly one `git-receive-pack`,
+  the fork has only `refs/heads/coder/feat`, and there is one `action.allowed`.
+
+Runs on this branch, single files:
+- publish.test.mjs: 13/13.
+- publish-socket.test.mjs: 8/8.
+
+## Mutant
+
+M1 removes the `publish-busy` line. Both tests fail:
+- The bus test fails at the first busy assert.
+- The cli test fails because the second publish answers `ok: true` with `ref: refs/heads/coder/other`.
+  That is the defect: two refs on the fork.
+
+Logs are in `/mnt/storage/scratch/megavolt-r237/` (m1-bus.log, m1b-cli.log). `cmp` confirmed
+broker.mjs matched the saved copy after the restore. The first cli mutant run (m1-cli.log) was against
+a hook that recursed on every checkPublish. I fixed the hook to fire only for branch `feat` and reran
+it (m1b-cli.log).
+
+## Residuals, not fixed here
+
+1. **A ticket that never ends holds its decision until the bus restarts.** `#publishes` is in memory.
+   That happens when the host dies between checkPublish and recordPublish or publishRefused. It fails
+   closed (`publish-busy`), and a restart clears it.
+2. **publish-timeout (sage-1440).** The socket files `publishRefused` and drops the ticket, but the bus
+   process's push may still be running. A retry on the same decision can then open a ticket while that
+   push is live. This is the same residual the socket already logs ("the bus process's push may still
+   reach the fork"). Closing it means the runtime's `remotes` must keep the decision busy until its push
+   settles, which reaches into runtime.mjs. That is beyond the brief's two options.
+3. **checkLand has the same shape.** `#landings` takes a ticket per call and the decision is spent at
+   `recordLand`. Whether two landings on one decision can both reach main isn't checked here. That's a
+   follow-up for Sage to row or dismiss.
+
+## Gate
+
+Per the brief: Duckworth approves the manifest, the bus suite and every `scripts/test-*.sh` are green
+on Sage's gate, and M1 is killed. This row also changes a cli test file, so the cli suite (or that file
+alone) should run on the gate too.

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

+| M2 | `settle` files publishRefused without trying recordPublish (hold only) | :302 at the wait for one allowed event, then :330 |
+
+Results (Sage's slot, sage-1686, 2026-10-21T03:35:00Z to 03:35:15Z): both killed, both restored
+(cmp ok).
+
+- M1: publish-socket 8/1, the row 242 test fails at :322 in 0.5 s.
+- M2: publish-socket 8/1, the row 242 test fails at :327 (the bounded wait at :311 for one allowed
+  event) in 10.3 s.
+
+## Suites
+
+On Sage's slot (sage-1686), on base 8fede5fc6 plus this row:
+
+- bus `node --test tests/*.test.mjs`: 499/499, 03:35:20Z to 03:35:34Z. This is one fewer than
+  Sage's 241 gate (500) because the base predates row 241's land.test case.
+- cli `node --test tests/*.test.mjs`: 566/566, 03:35:34Z to 03:43:47Z. That's 565 plus the
+  row 242 test.
+
+Singles before the slot: publish-socket.test.mjs 9/9, bus publish.test.mjs 13/13. The seat suite
+and scripts/test-*.sh are left for Sage's landing gate.
+
+## Residuals
+
+- The agent was told publish-timeout, but the push is recorded later and the run isn't
+  notified. The allowed event and the bus log line are the only trace. A later publish on the
+  decision gets decision-consumed, which tells the agent the decision was used. Whether the run
+  should get a RESULT for a late record is a follow-up question for Sage.
+- The hold lives in the bus process's memory, like the broker's open tickets. A bus restart during
+  a hold drops both, the same as today for any publish in flight.

 no defect is filed.

 Piece 1 is Jason's next real Mosaic Stack request to pm. It is not open yet.
+
+## 2026-10-21T01:14Z dates (sage-1622, Mos mos-1148, Vikunja #442)
+
+Mos accepted the plan with changes C1 and C2. The dates are latest-by markers (Q111).
+
+1. Pieces 1-5 open by 2026-10-23 23:59Z. Mos gives Jason the plain command after tonight's open items with him
+   (Q13 on PRD 1.8, the 1012 and 1008 boot). I don't ask again.
+2. C1: no piece is pinned to a copy. A piece runs on whatever copy is live when Jason sends it. For each piece
+   this log records the activation id at send. A piece still open across a window gets the new activation id
+   recorded too.
+3. C2: neither the Q175 phase 2 window (10-23) nor the 10-24 re-pin window rolls back or restores while a piece
+   has history, unless that window has failed. If a restore happens anyway, this log names the pieces to redo.
+4. All five closed and reviewed by 2026-10-26 18:00Z. Jason reads the five trails at his gate on 10-26 or
+   10-27. A pass starts merge plan step 1 under decision 146, and step 4 stays his.
+5. Fallback: if fewer than five pieces are open by 10-23, the gate moves to 10-28. No agent opens a piece in
+   Jason's place.
+
+When Jason sends a piece, I tell Mos its message id.
+
+Correction (2026-10-21T01:06Z): the heading above says 01:14Z. The clock read 2026-10-21T01:05:56Z when I wrote that entry, so 01:06Z is the right time.
+
+## 2026-10-21T01:20Z Jason's pre-S7 checks (mos-1154)
+
+Between 01:11:06Z and 01:13:03Z Jason sent pm five requests with `mosaic talk pm`: ed9e1e14, 51c19692,
+94f5d62c, 0645a3b7, f75449c0 (bus seq 1583 to 1591). pm run rc9e993da24cf answered each in 4 to 16 s. They were
+two jokes, the sandwich, the purpose of Mosaic Stack and pm's mission. pm made no task and raised no decision
+for any of them, and said so each time. Mos's reading, which I take: none is a piece, because a piece has to
+become work that gets closed and reviewed. They are recorded as Jason's pre-S7 checks. The five pieces are
+still open, latest-by 10-23 23:59Z. Activation at send: copy 4429a104f, as in the 01:06Z entry (C1). Source: Mos
+(mos-1154) read the bus. I didn't read the message bodies.
+
+pm also told Jason that its state snapshot lists only the first 50 of 198 open tasks and that it pages the rest
+with list_tasks. That is the row 109 (#1603) design: broker.mjs `state` returns `cap: TASK_PAGE` (50) with
+`total`, and list_tasks pages up to TASK_PAGE_MAX (200).

+# 10-24 window: re-pin 4429a104f to the row 234 landing, with the 3i-3j migration (draft 0)
+
+Sage, 2026-10-21T01:05Z, draft 0, for mos-1145 under DECISIONS Q173. This is the skeleton. NEW isn't fixed yet,
+so Mos doesn't check this draft. Draft 1 names NEW and goes to Mos for the P0 check. The step layout follows
+`repin-4429a104f.md`. Steps that match are named, not copied.
+
+## Scope (mos-1145, mos-1134)
+
+- One window carries the code of rows 190, 199 and 210, plus row 234 (row a) with its schema step 3i to 3j
+  through `activate --migrate`, agent-run under Q173, backup first.
+- Row a lands before the .53 and .54 installs, by 10-25 (mos-1134). If row 234 hasn't landed by 10-24 12:00Z,
+  I ask Mos whether to run the window without it (no migration) or to move it.
+- Jason has no step. Nobody acts as Jason. No pi (P19 383). No Save, no `mosaic name`. Nothing is pruned.
+- `--sso` stays off. Row 200's `activate --sso` is in NEW as a tool. Turning it on changes who reaches the Console
+  from outside, so that's Jason's (Q173 exclusion). It has its own window, the Q175 phase 2 window on 10-23
+  (mos-1148). That window runs first, so this window's OLD may be the phase 2 copy, and P1 reads it from
+  `status`.
+
+## Names
+
+- OLD, live: `4429a104f6d65ccf165f6c83b5d1dce3147dfde0`, schema 3i, pointer `pm: true` (record 99a406ed3).
+  P1 re-reads the activation id and the Console flags from `status`. I don't copy them from the last window.
+- NEW: open. It's the row 234 landing, or a later code landing if Mos rules. Candidates in landing order:
+  210 (r4 due 10-21), 237, 194, 234.
+- REPO, `P`, `WIN=agents/sage/work/window-repin-<NEW12>/`, `SNAP`: as in `repin-4429a104f.md`, with the
+  sha checks at P0 and before S1, S2 and any D3.
+
+## What NEW carries over OLD (so far, refactor c8bc5cf4c)
+
+`git log --first-parent 4429a104f..HEAD`, path-limited to packages, scripts, roles, contracts, adapters, skills
+and the package files:
+
+| Row | Commit | Live effect to check |
+|---|---|---|
+| 201 | afad4993f | business: access.json loader. Check: the live business has no access.json, and load stays LOAD_OK (P1). |
+| 204 | d0bbc5c1c | business: 193a viewer level. Same check. |
+| 190 | 00d4cc1f6 | Several instances per host. Touches `stack-release.sh`, `webui-service.sh`, `bus-service.sh`, `stack-copy.sh`. The default instance must render the same units: P2 diffs the rendered units OLD vs NEW for `mosaic-stack`, and any difference stops the window until it's explained. |
+| 200 | 9e1085816 | Tool: `activate --sso`. Off here. `--plan` must show no `--sso` line. |
+| 199 | cb5fdb064 | Credential store per agent. Check: bus start with no store entries for the live agents changes nothing, and the chief's and pm's launches still pass. The P3 rehearsal covers start. |
+| N3 | 390ea5261 | README only. |
+| 230 | c8bc5cf4c | Case 2 scripts, tools only. Not run live. |
+| 210 | open | Host access. The live business has no `hosts`, so nothing is granted. Bus start runs the host-run sweep (M34d). P3 must show it removes nothing. |
+| 237 | open | Publish busy check (199 N1). |
+| 234 | open | Machine grant row a and the 3i to 3j schema step. `--plan` must say `migration: 3i -> 3j`. |
+| PRD 1.7+1.8 | open | `docs/prd/mosaic-stack.md` and `packages/tasks/requirements.json` move to version 1.8 (mos-1154, mos-1156, DECISIONS Q192). The live pm cites 1.6 until this window. Check after: the pm's requirements read answers version 1.8. |
+
+Service script drift OLD to HEAD is 415+/91- over the four scripts, mostly row 190. P5 holds them at NEW.
+
+## Backups and the migration
+
+- W5: the stopped store backup that every activate takes (row 185), with SHA256SUMS, SCHEMA 3i and STAMP,
+  plus the rollback set. Before `--migrate` writes, I check that SCHEMA reads 3i and the backup SHA256SUMS hash.
+- W0b: the business file copy, as in the last window.
+- Rollback after a migration isn't the plain rollback. OLD is 3i and the store is 3j, so going back needs
+  `--restore <W5 activation>`, and that loses the events written after W5. The row 181 restore guard counts
+  11 tables, and the untimed ones need the D3 snapshot. Mos decides any restore past W5, as before.
+- P3 is the rehearsal with `--migrate` on a copy of the live backup. It must show the 3j step and the row
+  counts before and after.
+
+## Row 42 (S7) interaction
+
+Row 42's pieces may be in flight at window start (sage-1622, mos-1148 C1 and C2). W1 adds: list open pm tasks, and either pm
+finishes or parks them before W5, or I record which piece crosses the window. No restore while a piece has
+history unless the window fails.
+
+## Open before draft 1
+
+- Q1: NEW, once 234 lands. Do 194 and 237 go in if they land first? I recommend yes for 237 (small, bus
+  only) and asking Mos about 194, since 194 changes the lifecycle verbs and roles/chief-of-staff.*.
+- Q2, settled by mos-1148: phase 2 is its own window on 10-23. Draft 1 takes OLD and the Console flags,
+  `--sso` included, from `status` after that window.
+- Q3: who operates. If Darkwing is free, Darkwing operates and I check. Otherwise I operate as in the last
+  window.
+- The P-step evidence list for rows 199 and 210 at bus start, written once both have landed.

+refuses `config-console-key` before anything stops when the config holds a

+## Brief: #436b Gitea grant path, build (schema 3j-3k)
+
+Sage, 2026-10-20, for Vikunja P19 #436 (#436b), mos-1124 (Q190: each seat gets its own Gitea account through
+this row) and mos-1145 (Gitea moves to 10-27, at risk). Owner Megavolt, reviewer Dewey, gate owner Sage.
+Gitea #1742.
+
+The design is `agents/megavolt/work/436b/DESIGN.md` r5 at 1be535aca on `megavolt/row199`, sha256
+`68df02cdf890564c6ed0a5426204114389ba7eb0eea1cf04f1bf5938b6de45f4`, which Dewey approved in dewey-0763. Section 7
+was approved by Duckworth at fa5658941 (duckworth-0067) and is unchanged since. It is not reopened here. The
+build also takes `agents/megavolt/work/436b/BUILD-CARRY.md` at 3330c901b (Dewey's N9 and N10), and its BUILD.md
+cites that file.
+
+Scope: the Gitea half only. The binding (section 2), the executor and its admin credential (sections 3 and 4),
+failure and restart (section 5, with sage-1578's option (b): a step 0 refusal stays unspent only until the
+next start), revoke and sweep (section 6), the store records (section 7) and section 9's tests and mutants. The
+GitHub half (section 10, Bushroot) is not in this row.
+
+Order and schema:
+- It builds on row 210's landing (the design: code waits on 210) and on machine grant row a (row 234), whose
+  section 7 rule and `system/grant` writer it shares.
+- This row owns `SCHEMA_VERSION` 3k: its two tables go in `3j-3k.sql` on row 234's landing. Row 206 (193b2)
+  moves to 3k-3l and rebases onto this row's landing (Sage, 2026-10-20: row 205 is still queued behind the
+  federation rows, so this row lands first).
+
+Boundaries:
+- Live use waits for Jason. He approves section 8's notes (the admin token can take over any account on that
+  Gitea) and does the one bootstrap step himself (3e): he creates `mosaic-grant`, its TOTP and its token. No
+  agent creates a Gitea account or token (Q188).
+- No test reaches git.mosaicstack.dev or any provider. Tests use a fake Gitea and fake tokens in scratch roots.
+- Seats keep pushing as jason.woltje until this row is live and Jason grants their accounts (mos-1124).

+
+One decision can push its commit to two fork refs, because `checkPublish` doesn't refuse while another ticket
+holds the decision. Pick one fix and say why in BUILD.md: refuse `publish-busy` in `checkPublish`, or recheck
+`#spent` in `publishTarget`. Add a test where two tickets race on one decision and exactly one push happens,

+Megavolt, reviewer Duckworth, gate owner Sage. Builds on row 237's landing d7d943199. Vikunja P19 441.
+
+Landing already has three guards against one decision landing twice. `land-busy` at
+`packages/cli/src/git-socket.mjs:351` allows one landing per socket at a time. `finishLand` moves main by
+compare-and-swap (`packages/seat/src/working.mjs:391`, refusing `base-moved`). `recordLand` reruns
+`#landFacts`, which refuses `decision-consumed` (`packages/bus/src/broker.mjs:945`). So no end-to-end race
+exists, and no code change is planned. What's missing is a test that pins each guard.
+
+- In `packages/bus/tests/land.test.mjs`, add a test where two tickets pass `checkLand` on one decision. The
+  first `recordLand` succeeds and the second refuses `decision-consumed`, with nothing recorded for it.
+- Run three mutants and list them in BUILD.md: drop the `#spent` line in `#landFacts`, drop the old value
+  from the CAS `update-ref` in `finishLand`, and drop the `land-busy` throw at git-socket.mjs:351. Each must
+  be killed by a named test. If the CAS mutant survives `packages/seat/tests/working.test.mjs:555`, add a
+  test to working.test.mjs that kills it. Otherwise leave that file alone.
+- If a mutant survives with no test that can reach it, stop and send me the analysis. Don't change source
+  to make a test reach it.

+The git socket gives up with `publish-timeout` (`packages/cli/src/git-socket.mjs:433`) while the bus

+retry to another branch can then push a second ref to the fork.

+
+Sage, 2026-10-20, for Vikunja P19 #436 (#436a), mos-1141 and mos-1143. Owner Gizmoduck, reviewer Duckworth,
+gate owner Sage. The design is `agents/gizmoduck/work/machine-grant/DESIGN.md` r6 at f9039682e on
+`gizmoduck/machine-grant-design`, which Duckworth approved for code once row 210 lands (duckworth-0063,
+mos-1141). It is not reopened here. Section 12 Q-S4 defines the split. Estimate 1.5 days. Gitea #1740.
+
+Row a ships enrollment as the approved request (section 3), the four `tools/host` files, the store records
+and their migration `3i-3j.sql` (section 5), `host.run` reading the records, and `hosts status`. It also
+moves row 210's tests onto the store. Every grant name is under `grant.*` behind one guard, as
+`action.allowed` bodies (mos-1144, gizmoduck-0086, duckworth-0065 O1). No agent creates a grant (Q188).

+Order and timing:

+  role grants from the business file before that re-pin (design r5 N9).

+# 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).

+## I3 the upgrade command and the host run sheet
+
+Gitea #1735. Vikunja P19 #432.
+
+### Problem
+
+Nothing re-pins a stack whose units are root's. r6 designed `case1-repin.sh` for .53 alone. And nothing
+tells ops-01 what to put on a fresh host before install.
+
+### Owner and reviewer
+
+- Owner: Darkwing. Fallback author: Herb (mos-1118, mos-1119). If I1 isn't approved by 10-23, Herb takes
+  I3 from this brief with no new briefing.
+- Reviewer: Filbert (moved from Duckworth, mos-1119 item 4).
+- After: I1 lands. It calls I2's render, so its tests use I2's candidate or a stand-in with the same
+  arguments.
+
+### Files owned
+
+`scripts/stack-upgrade.sh` (new), `packages/cli/tests/stack-upgrade.test.mjs` (new),
+`docs/guides/host-run-sheet.md` (new), and the `docs/TOOLS.md` lines for the new script.
+
+### What ships: `stack-upgrade.sh`
+
+Root runs it from a root-owned checkout of the reviewed commit, never from a copy, because the stack's user
+can write the copies.
+
+- `stack-upgrade.sh upgrade --instance NAME --bundle FILE --sha SHA [--migrate] [--timeout S]`
+- `stack-upgrade.sh rollback --instance NAME --to ID [--restore ACT --events N] [--timeout S]`
+
+The steps are r6's activate A1-A5, A2f and R1-R4 (r6 :459-544), and r6's rollback (:545-559), with these
+changes:
+- The unit render is I2's, called with the values from `/etc/mosaic-stack/<instance>.args`, which I2's
+  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).
+
+## I4 hostcheck: the bwrap profile check, pins and boot unit
+
+Sage, 2026-10-21, split out of I3 (darkwing row 233 G2, sage-1650). Owner Darkwing, reviewer Filbert, gate
+owner Sage. Darkwing builds it right after I3, and it must land before the ops-01 proof.
+
+### Problem
+
+The host run sheet (I3, line 182 above) lists r6's `hostcheck` among the host items for any host that runs
+bwrap, and I3's A1 refuses `profile-drift` unless `/usr/local/lib/mosaic-stack/hostcheck.sh --check` exits 0.
+No hostcheck exists on refactor. It's r6 B2 (row 195 DESIGN.md at b7239bb66, :262-303 and :839-860), sized at
+150-200 lines of bash and 350-450 of test. That's work separate from the upgrade sequence: the root-side bwrap
+stop and a network fetch.
+
+### What ships
+
+r6 B2 as designed:
+- `case1-pins.sh` holds the pins: the profile sha256, the apparmor-profiles version and the bubblewrap pin.
+- `hostcheck.sh` covers the seven items in three modes:
+  - `--check` exits 0 or 1.
+  - `--enforce` stops bwrap: `apparmor_parser -R`, then `root:root 0700` on `/usr/bin/bwrap`. It writes
+    `/etc/mosaic-stack/DRIFT` and a `hostcheck.log` line, and exits 0.
+  - `--upstream` compares the current apparmor-profiles deb to the pin.
+- `mosaic-hostcheck.service`, a boot oneshot.
+- `case1-hostcheck.test.mjs` uses fakes for every host tool and covers r6's seven case groups and seven
+  mutants.
+
+The I3 run sheet's hostcheck item points at this row. I3's A1 and its fake don't change.

+  chief of staff requests and the user approves. Jason approved it in T3,

+- Version 1.8 source, Jason's ruling Q188 (DECISIONS, 2026-10-20), his
+  answers to Q8 and Q10, in part. Q8: "I would rather grant the grant
+  right to an agent that runs with strict guardrails. That agent presents
+  the final authorization for the user. Upon approval, the grant is
+  created programmatically. I see this as: User configures their PATs, API
+  tokens, authorizations within the WebUI. The agent presents the request
+  for grant with X rights for another agent. The user reviews, then clicks
+  Approve/Deny. Click of Approve fires off protected mechanical methods to
+  handle the grants on Github, Gitea, .... services as needed. The tooling
+  would need to exist and must be guarded." And "Disallowing the agents to
+  create grants autonomously is a necessary evil for better security.
+  Requiring the user to manually perform the steps is a no-fly." Q10:
+  "Agents should have tools and command access based on roles. Those roles
+  dictate the allowed tools and commands. The use of a tool or command
+  should not be raised to the user unless the system is configured with a
+  manual mode that requires user interaction. By default I want to have
+  the agents capable of running commands and tools at will within their
+  sandbox/guardrails. This allows autonomous actions by agents within
+  their lanes. Perhaps a "Trusted actions within approved guardrails"
+  methodology." And "The main agent or chief of staff would be responsible
+  for surfacing the request to the user's inbox for approval. Not all
+  agents are capable or authorized to request directly. It must follow the
+  chain of command properly." He agreed with Mos's Q10 points 3 to 6:
+  protected stack code does every step on Approve, his tokens are entered
+  in the WebUI and agents never see them, a command on the approved list
+  runs without a click and any other is refused, and he, Mos or the tester
+  can revoke a grant at once.

+- Version 1.8 source, Jason's ruling Q191 (DECISIONS, through Mos in
+  mos-1149), that the assistant and the chief of staff are separate roles,
+  and only the chief raises a grant request: "Q13: that looks better".
+- Version 1.7 source, TARGET.md line 66: "Chief of staff agent has
+  hire/fire authority for agents as needed; unless user forbids per
+  agent". And Jason through Mos (mos-1067), DECISIONS Q183, in part: "I
+  will still want to allow infra agent(s) on my .53 instance to access
+  other servers, etc. However, not all agents will need to have that
+  access. I envision a credential store within Mosaic Stack that works as
+  some sort of variable for the agent to call. The system will enforce
+  access to the credentials to keep the agents sandboxed with proper
+  security. I need to be able to trust my agents with assisting me. This

+    plain work actions: sending messages, writing records, asking for

+    actions of an assigned task. A role holding any other action, such as
+    launch, end, organization, naming, hire, review verdict or merge
+    authority, or any action added later, is never hired. So the chief
+    never hires a chief, never picks its own reviewers or merge gate, and
+    the author is never the reviewer. This holds whatever the role file's
+    list says. Adding to that list is a PRD change.
+  - The chief may set a hired instance's model and narrow its limits, and
+    nothing else about it.
+  - The user can forbid per agent. The user marks an instance so the chief
+    can't fire it, end its runs or change its model, and marks role kinds
+    the chief can't hire. Only the user changes these marks, through the
+    WebUI or the CLI.
+  - The kill switch stops every hire and fire while it is on.
+  - Every hire and fire is logged with the chief's instance, its run and

@@ -289,8 +379,111 @@ Added in version 1.2:
  - in Vikunja, a `bot-<business>-<role>` user per role, plus one
    read-only `bot-<business>-sync` that does all polling (lead
    decisions 52 and 58).
+
+  Since version 1.8, a token or key for a grant is made by the grant code
+  on the user's Approve (REQ-GRANT-2), not by hand. Tokens that exist stay
+  as they are.
 - **REQ-CRED-2.** A session that finds only founder credentials stops.

+Added in version 1.7:
+
+- **REQ-CRED-3.** An agent with a grant can run commands with sudo on
+  another host. The agent asks for the host credential by name. The stack
+  checks that a grant exists for that agent and that host before the
+  credential is used. The agent never sees the key or any other secret
+  value (REQ-CRED-1, REQ-VAR-2). An agent without a grant for that host is
+  refused. Not every agent gets a grant. Who grants a host credential, and
+  how, is set by the #424 design, which Jason approves.
+
+Added in version 1.8 (Q188):
+
+- **REQ-CRED-4.** An action a role definition lists within-role, and that
+  uses a grant, runs without a decision for each use only when all of
+  these hold:
+  - the definition declares the credential kind the action uses;
+  - a grant names that agent, and that host or service;
+  - for a command, the command matches the grant's allowlist. A grant
+    lists exact argv prefixes. A wildcard grant is refused;
+  - the agent's key or token for that grant is issued and not revoked.
+
+  A command off the allowlist is refused, and adding one takes a new grant
+  request (REQ-GRANT-1). An action whose definition doesn't list it
+  within-role still needs a decision for each use. Only a reviewed role
+  change adds an action to a definition. `host.sudo` routes under this
+  requirement.
+- **REQ-GRANT-1.** No agent creates or writes a grant. A grant request
+  follows the chain of command, and only the chief of staff raises it to
+  the user's inbox. Any other role that needs a grant for itself or for an
+  agent it directs asks the chief of staff, through its chain: a worker
+  role through its PM, the PM and the CTO directly. The assistant passes
+  the user's own request to the chief of staff (REQ-ASSIST-1). The request
+  names the agent, the grant method and its target, the exact rights, and
+  a rotate-by or expiry date. The chief raises one only for an agent whose
+  reviewed role definition allows that kind of credential, and the broker
+  refuses any other. A grant can't name a wildcard, a shell or an empty
+  command. The request is a decision with the action `credential.mint`, so
+  it goes to the user as a hard wait (REQ-WAIT-1). A grant whose method
+  makes an account, such as a seat's own Gitea user (Q190), is the same
+  one decision: the method in the grant says it makes an account, the
+  request names the account, and the inbox shows the account name before
+  Approve. The user's one resolution covers the account and its
+  credential, so the hard-waits list doesn't change. An `account.create`
+  raise isn't a grant request and routes as version 1.7 has it. The broker
+  checks only that the chief of staff raised the request. The chain of
+  command before that is in the messaging lists and the role contracts,
+  not a broker check. The assistant and the chief of staff are separate
+  roles. No agent holds both, and the broker refuses a claim that would.
+- **REQ-GRANT-2.** The user approves or denies each grant request in the
+  inbox. Approve is the only thing that creates a grant, and the code uses
+  a grant only when it has a matching Approve record. No agent creates a
+  grant. A grant written into the business file by hand makes nothing. Row
+  210's hand-written grants stay a test path until Vikunja #436a moves
+  `host.run` to grants made by Approve. On Approve, protected stack code
+  does every step, not an agent and not the user: it records the grant,
+  makes the key or token, installs it on the machine or creates it on the
+  service, and logs each step. On Deny nothing is made, and the denial is
+  logged. The grant methods are:
+  - machine key: a key for one agent on one enrolled host, with the
+    command allowlist of REQ-CRED-4. A host's identity comes from the host
+    side when the user approves its enrollment, never from a first
+    connection. A host user with sudo receives a grant only after the user
+    approved that user by name;
+  - Gitea: a token for one agent, and for an agent seat its own Gitea user
+    (Q190), with an expiry. The all scope and the admin scope are never
+    granted;
+  - GitHub: a grant for one agent.
+
+  The Gitea and GitHub rights units come in a later design that Jason
+  approves.
+
+  The approval binds the exact rights the user saw and the target or its
+  enrolled identity. A change to the agent, its definition, the target,
+  the target's identity or the rights after the raise voids it. An
+  approval is used once. A grant the code couldn't finish is undone at
+  once on the stack's side, so it is never used. What it left on the host
+  or service stays visible as pending until it is removed, as for a revoke
+  (REQ-GRANT-4). A new grant needs a new approval, never an automatic
+  retry. The grant code runs only on a request the user resolved. A
+  request resolved by an arbiter, the tester or any agent makes nothing. A
+  `credential.mint` decision raised before version 1.8, or without the
+  fields of REQ-GRANT-1, makes nothing when it is approved. Until the
+  Console knows the signed-in human (Vikunja #412), Approve is
+  `mosaic decide` in the CLI (REQ-DEC-3).
+- **REQ-GRANT-3.** The user enters their own personal access tokens and
+  API tokens in the WebUI, or the CLI. Only the grant code reads them, to
+  make grants. No agent ever sees a token value or a key's private half.
+  Values appear in no event, log, message, prompt or agent file, and no
+  agent can read them back (REQ-VAR-2). Until the Console knows the
+  signed-in human, they are entered through the CLI.
+- **REQ-GRANT-4.** A grant can be revoked at once by the user, by the
+  assistant for a grant in its own organization, or by the tester on a dev
+  instance (Q173). A revoke needs no decision and no new trust. It takes
+  effect at once on the stack's side, without waiting on the network, so
+  the next use is refused. Removing the key or token at the host or
+  service follows. Until that removal is done it stays visible as pending.
+  A revoke while the grant is being made stops it, and nothing it made
+  stays usable. Every revoke is logged with who made it.

+- **REQ-TRUST-1.** Agents act within their role guardrails without asking.
+  The default mode is "trusted actions within approved guardrails". An
+  action a role file grants within-role is done at will, inside the

+  nothing to the user. An action the file doesn't grant within-role still
+  routes by REQ-DEC-2, and a hard wait still goes to the user
+  (REQ-WAIT-1). Only a reviewed role change adds an action to a role file,
+  and REQ-WAIT-2 still keeps every hard wait out of every role file.
+- **REQ-TRUST-2.** The user can put chosen actions in manual mode. The
+  organization file holds the list of actions in manual mode, empty by
+  default. While an action is on the list, every use of it by any role
+  becomes a decision for that use, raised to the user, and the action
+  waits until the user resolves it. A decision denied, or not resolved,
+  refuses the action. Each decision is used once. For a command on another
+  host, the decision names the host, the command and its input. Actions
+  not on the list are unchanged. Only the user changes the list, through
+  the WebUI or the CLI. The chief of staff's organization writes
+  (REQ-ROLE-3) can't change it, and no agent can. Every change is logged

+Added in version 1.7:

+- **REQ-LAND-2.** A coder pushes its own work to its own fork. The action
+  is `git.push.remote`.
+  - What it pushes: one commit, by its oid, never a ref name. That commit
+    is the latest work commit the bus recorded for the coder's task, and
+    the coder made that push. A decision that authorizes a push names that
+    commit, and it doesn't authorize any other.
+  - Where it lands: only the branch
+    `refs/heads/<its Gitea user>/<branch>`. The host builds that name, the
+    agent never does. A push never forces.
+  - Which remote: the agent's own fork of the project's upstream. The
+    business file names the upstream, and the host never contacts it. For
+    each push the host builds the fork's address over https from the
+    upstream's host, port and repository name and the agent's own Gitea
+    user. The history check, the push and the credential match all use
+    that address. So the agent's own user owns the receiving repository on
+    every push, and the agent never names it.
+  - The host refuses an upstream on a host or port other than the agent's
+    Gitea, and an upstream the agent's own user owns. It refuses a fork
+    that is missing, empty or doesn't share the project's history. Gitea's
+    push-to-create stays off, so a push never creates a repository.
+  - Who may: the action routes under REQ-DEC-2 and is granted within-role
+    to the coder role only. No other role file grants it.
+  - Before version 1.7 the action was a hard wait under REQ-WAIT-3, so
+    each push needed a decision the human resolved, and that decision

+# Root runs it from a root-owned checkout of the reviewed commit outside
+# <home>, never from the release, because <user> can write the release. It
+# writes both units under /etc/systemd/system as root:root 0644, runs
+# `systemctl daemon-reload`, enables both, then starts the bus and then the
+# Console (Q189). Both come back after a boot on their own. It never links
+# a unit file into place, and it opens no file under <home>: it only stats the
+# copy, its scripts/mosaic and the proof file. It renders the default
+# instance only.
+#
+# The library profile takes exactly these serve flags, each once:
+#   --port N (1..1023)  --business ID (the unit's)  --public-host NAME
+#   --auth-header HEADER  --allow-user ID  --send
+#   --proof-header NAME  --proof-file PATH
+# The factory profile takes --port N (1..1023) and --business ID, and an
+# optional --tester-port N (1024..65535, never --port). Only factory takes
+# --pm and --claude.
+#
+# On a re-install the installed units must equal the render in everything
+# but the copy id, and both must name one copy, so a re-pin or rollback
+# re-renders the pair together. A unit that was already running stays on its
+# old copy, since `systemctl start` leaves it alone; the script says so and
+# that the bus and Console must restart together, and restarts nothing.

Gizmoduck: row 210 r5 start and in-review round 3 (2607-2611). Duckworth: row 210 round 3 record, approve (2614). Megavolt: row 241 claim (2606).	2026-10-20 21:50:59 -05:00
jason.woltje	f5753c0e8d	host access: agent host sudo through the credential store, host.run over broker.sock (row 210, #1707 ) Blobs of Gizmoduck's r5 `0485384e9` on origin/gizmoduck/row210-r5 (base `ad95c888c`), the 23 manifest paths, manifest 688d38b9. Duckworth approve round 2 (rev 2592) and round 3 (comment 29851, rev 2614). Round 3 is a rebase-only round over row 237 (`d7d943199`): broker.mjs is a clean 3-way merge (610af0c4), the 210 hunks sit away from 237's insert, and range-diff against r4 `c43008749` is all equal. Mutants 52 of 53 killed on the merged tree. M22b is equivalent (rev 2584); its coverage moves to row 235. Preflight singles: seat sandbox 10/0, bus project-runtime 3/0. Gate on `ad95c888c` plus these paths: 15 package suites 2796 pass 0 fail, 10 scripts/test-*.sh suites 429 pass 0 fail (plus 156 node tests in the queue suite). Refactor moved to `9d165be8c` since, two briefs touching no manifest path. No live change: the stack runs from copy `4429a104f` until the 10-24 re-pin window.	2026-10-20 21:47:11 -05:00

jason.woltje	d7d9431990	bus: one decision, one open publish; checkPublish refuses publish-busy while another ticket holds the decision (row 237, #1743 ) The decision is spent only at recordPublish, after the push, so two checkPublish calls on one decision could both push and land the commit on two fork refs. checkPublish now refuses publish-busy while an open ticket holds the same business and decision. A refusal drops the ticket and leaves the decision unspent. Broker test and a socket race test with exactly one git-receive-pack. Residuals 1-3 in BUILD.md; residual 3 (checkLand) is a follow-up row.

jason.woltje	cb5fdb064f	credentials: a credential store per agent, its own git identity, pushes to a remote (row 199, #1697 ) Squash of Megavolt's 627979a17..86963d281 on origin/megavolt/row199-on-190 (base `00d4cc1f6`, row 190's landing), the 37 manifest paths, build.patch 05383075, manifest 35f900fd (Duckworth approve round 1, comment 29779, rev 2540). Mutant batches 1 and 2 in agents/megavolt/work/queue-199/BUILD.md: batch 2 26 of 28 killed, M17 and M27 equivalent. docs/TOOLS.md is a 3-way merge with row 200 (`9e1085816`): row 199's hunk applies unchanged (patch-id d88379111e2e) and no test reads the file. Gate on `9e1085816` plus the patch: 15 package suites 2735 pass 0 fail, 10 scripts/test-*.sh suites 429 pass 0 fail (plus 156 node tests in the queue suite). Refactor moved to `76134dfde` since, a brief touching no manifest path. No live change: the stack runs from copy `4429a104f` until the 10-24 re-pin window.	2026-10-20 19:23:12 -05:00

jason.woltje	9e10858160	stack-release: activate --sso for the Q175 phase 2 window (row 200, #1698 ) Squash of Launchpad's 30e4bb1a3..9df40878f (round 3 on row 190's landing `00d4cc1f6`), the 3 manifest paths: scripts/stack-release.sh, packages/cli/tests/stack-release.test.mjs, docs/TOOLS.md. Manifest b3ead55c8b48 (Webby approve round 3, rev 2539, comment 29772). Patch b2a8f5de18b7. Gate on `9df40878f`: 15 package suites 2675 pass 0 fail, 10 scripts/test-*.sh suites 429 pass 0 fail (plus 156 node tests in the queue suite). Mutants 13 of 14 killed, M12 the ruled equivalent (sage-1446). Refactor moved to `722136772` since the base, touching none of the 3 paths. No live change: the stack runs from copy `4429a104f` until a re-pin.	2026-10-20 19:09:00 -05:00

jason.woltje	01b40d3576	plans: C2-13a rulings for gosalyn-0065. G1: default instance only, no --instance, a named instance is a follow-up. G2: library refuses --sso for 10-27, preview set and proof pair stay, --sso waits for Q175 phase 2. Line cites moved to their places after rows 190 and 192 (webui-service.sh, stack-copy.sh, bus-service.sh, serve.mjs), and the Console's WantedBy replaces :41	2026-10-20 18:09:04 -05:00
