row 285: mos-1333, withdraw the publish fence; N10 option (a) with an assistant instance; a chief with its gitea ref, identity and publish loads; restore the creative publish test; BUILD.md gate scope (sage-2946) (#1790)

The fence sits near business.mjs:166, clear of row 287's :283-291. Its message
starts with the N10 text. An assistant-instance test keeps the no-gitea branch
covered, and a creative-instance test covers the fence. Nothing here has run.

-# Row 286: C2-03b push and per-seat credentials for the library mirror (#1791)
-
-Owner Ludwig. Reviewer Dewey. Gate owner Sage (sage-2909).
-Brief: `docs/plans/2026-10-20_case2-rows.md`, "## C2-03b", at 94c33a43c. Design 7.2 and the ruling
-after r11 "agents never write story" in `agents/gosalyn/work/case2/DESIGN.md` at b68d79663.
-Base: `refactor` at 94c33a43c. The brief cites aca16404c, and lines have moved since:
-`GRANT_EVIDENCE` is `broker.mjs:253` now, not `:246`.
-
-Status: code written, local and unrun (18:48Z on). No node until Sage's CLEAR, after row 258's run.
-
-## What the code does today (94c33a43c)
-
-- `packages/library/src/sync.mjs:32` `syncCommand(kind, url, {mirror, branch, user, slot})`. It refuses
-  any kind but `fetch`. The env passes `MOSAIC_LIBRARY_HOST`, `_USER` and `_SLOT` to `bin/askpass`.
-- `bin/askpass` checks `-f` and `! -L` on the slot, then reads it. It doesn't check the uid or the mode.
-- `sync.mjs:51` `slotPresent` checks lstat: a regular file, our uid, no group or other bits.
-- The slot path is built in `packages/bus/src/runtime.mjs:211-217` (`syncOptions`) as
-  `<configDir>/secrets/<business>/library-gitea`. The broker only calls `this.#library.sync(context,
-  {accept})` (`broker.mjs:4630`), and the timer calls `libraryModule.sync` directly (`runtime.mjs:533`).
-- The sync state file has a strict key list in `packages/library/src/mirror.mjs:222`.
-- `chief-of-staff` is a definition (`STAFF_TO`, `broker.mjs:240`), not a fixed instance name.
-- A seat's Gitea user is in `gitea_grants.user` and `gitea_users`. Its token file is
-  `<storeRoot>/<business>/<agent>/gitea` (`gitea-grant.mjs:379`). `giteaKeys.held(business, agent)`
-  answers the held case.
-
-## Plan
-
-1. `syncCommand(kind, url, {mirror, branch, user, file, commit})`. `kind` is `fetch` or `push`. Same
-   `SAFE` prefix, `-c` keys and env for both. A push is
-   `push --porcelain --no-verify --end-of-options <url> <commit>:refs/heads/<branch>`, with no `+`.
-   `commit` must be a full sha. The env var stays `MOSAIC_LIBRARY_SLOT` but now names whichever file
-   answers: a seat file, the chief's file, slot `library-gitea` or slot `library-human`.
-2. `push(context, {commit, credential, retried, command})` in `sync.mjs`. git's porcelain line for
-   the ref decides:
-   - `!` with `[rejected]` and `(fetch first)` or `(non-fast-forward)` means the tip moved. Fetch once
-     with the same credential and return `{pushed: false, raced: true, tip}`. With `retried: true`, the
-     same rejection refuses `stale-base`. C2-02 owns the re-apply.
-   - Any other failure refuses `library-push-failed`. git's stderr isn't kept.
-   - A remote that fails C2-04's URL rules refuses `library-remote-invalid` before any git call.
-3. `bin/askpass` gets `readSecretFile`'s checks, the same way: no symlink, the bus's uid, mode 0600.
-   In sh: `test -f && test ! -L && test -O`, plus a mode check through `stat -c %a`. Only the path
-   reaches that argv. The user check stays an exact match on the one configured user. The check and the
-   read happen at different times (TOCTOU). The bus owns the directories, so I take that as the
-   accepted limit (Q1).
-4. Credential choice for the fetch, as a pure function `fetchCredential(store, business, keys)` in the
-   bus. The broker exposes it, and `runtime.mjs` passes its answer to `sync` for the verb and the timer:
-   - The chief is the one instance whose definition is `chief-of-staff`.
-   - Evidence: `SELECT 1 FROM events WHERE business=? AND ${GRANT_EVIDENCE} AND
-     json_extract(body,'$.method')='gitea' AND json_extract(body,'$.agent')=?`, of any action. It
-     names no project and never reads `gitea_grants`.
-   - No evidence: slot `library-gitea`, `{kind: 'slot'}`.
-   - Evidence, a live `gitea_grants` row for the chief and not held: `{kind: 'chief', user, file}`,
-     with the user from that row. The fallback test never reads the table. This path does, because it
-     needs the user.
-   - Evidence and anything else (revoked, fired or held): `library-fetch-no-grant`, before any file is
-     opened.
-   - No chief instance (fired): Q2.
-5. The sync state gets `credential: {kind, user} | null`. `library.status` shows it.
-   `library-fetch-no-grant` shows as `lastError.code`. This changes `mirror.mjs`'s key check (Q3).
-6. Slot `library-human` is `<configDir>/secrets/<business>/library-human`. `humanCredential(...)`
-   refuses `library-human-missing` before any git call when the slot is missing or fails the file checks
-   (lstat: regular file, our uid, 0600). Her Gitea user: Q4.
-
-## Files owned extension (sage-2922)
-
-Added to the brief's list: `packages/bus/src/runtime.mjs` (`syncOptions` at :211-217 and the timer's
-call at :533) and `packages/library/src/mirror.mjs` (the state key list at :222). sage-2922 wrote
-`packages/library/src/runtime.mjs`, but the file is `packages/bus/src/runtime.mjs`. In mirror.mjs
-the row 222 contract holds: keys are added and none renamed. Before in-review I grep `packages/*/tests`
-for hash pins and path reads on both files and check them against every in-review manifest.
-
-## Scope questions (for Dewey and Sage before code)
-
-- Q1. The askpass TOCTOU above. Is it accepted as is, or should the helper be a node script that does
-  O_NOFOLLOW plus fstat? If node, it would read the token in process and print it to git's pipe.
-- Q2. Fired chief. The instance and its `gitea_grants` row are gone, so I can't name the agent for the
-  evidence check. My recommendation fails safe: with no chief instance, the fetch refuses
-  `library-fetch-no-grant` when any gitea grant event exists in the business, and uses the slot only
-  when none exists.
-- Q3. Files owned names `sync.mjs`, `askpass`, `broker.mjs` and the tests. The choice also needs
-  `packages/bus/src/runtime.mjs` (`syncOptions` and the timer's call) and
-  `packages/library/src/mirror.mjs` (the state key list for `credential`). I'd add both to the
-  manifest, with only those hunks changed.
-- Q3: approved, sage-2922. See above.
-- Q4: sage-2922 allowed `user` only if design 7.2 or the ruling after r11 makes it her account. Neither
-  does. `packages/library/README.md:31` at 94c33a43c says "`user` is the bot account name from design
-  step 3, required for sync", so it is the fetch identity and can't be reused for her save. Back to Sage.
-  My recommendation: `humanCredential(context, {user})` takes her login as a parameter, so this row adds no
-  mapping field. The row that adds the save, C2-02 or C2-11a with `editor`, names the field. That
-  needs a mapping schema change, which is Sage's call.
-  Ruled sage-2925: accepted. `humanCredential(context, {user})` refuses `library-human-missing` before
-  any git call when the slot is missing or bad or `user` is missing. This row adds no mapping field.
-  Row 283 (C2-01d) adds an optional `editor.user`, and row 288 (C2-02) passes it in.
-- Q4 (original). Her Gitea user for `library-human`. The entry's `user` (`mapping.mjs:52`) is today the sync
-  user, the bot's. The design names `editor {name, email}` (C2-11a) but no Gitea login. My
-  recommendation: the entry's `user` becomes her Gitea login, used only with slot `library-human`. The
-  fallback fetch keeps that same user too, because the bot slot was set up for it. Otherwise this row
-  takes the user as a parameter and C2-02 or C2-12b names the field.
-
-## Tests (brief list, mapped)
-
-T1 push lands a fast-forward. T2 a moved tip reports the race. T3 a second race refuses `stale-base`.
-T4 a dead remote refuses `library-push-failed`. T5 askpass answers with the named seat's user and file,
-and refuses another seat's user, a symlink, 0644 and another uid (with a fallback note if the test can't
-chown). T6 the fetch uses the chief's file with a live grant, and the slot only with no chief event.
-T7 revoked (through `grants.revoke`), fired (through `instance.fire`) and held each refuse
-`library-fetch-no-grant` with a valid slot present, and each asserts the `gitea_grants` row is gone
-first. T8 a chief grant on another project ends the fallback. T9 T7's three cases with the slot at 0000.
-T10 a missing `library-human` refuses `library-human-missing` and runs no git. T11 a token search of
-argv, the mirror config, the run log and the test output. Mutant: a `+` added to the push refspec fails.
-
-## Gate
-
-Dewey approves the manifest. The library and bus suites, plus every `scripts/test-*.sh`, pass on Sage's
-gate. The mutant dies. A token search of the run's output finds nothing.
-
-## Early look (dewey-0860), folded
-
-Q1, askpass: sh, with no gap between the check and the read. The helper keeps `test -f` and then:
-- opens the slot with `exec 3<"$slot"`;
-- stats the open file with `stat -L -c '%d:%i %u %a %s %F' /dev/fd/3`, and the path itself (an lstat)
-  with `stat -c '%d:%i' -- "$slot"`;
-- refuses unless the two dev:inode values match, the type is regular, the uid is `id -u`, the mode is
-  600 and the size is at most 16384;
-- reads the token from fd 3.
-A symlink or a swap at either moment changes the inode, and the token comes from the file that was
-checked. This matches `readSecretFile` (`gitea-grant.mjs:167-181`).
-Residual, the same on both paths: a FIFO swapped in after `test -f` blocks the open. Neither side uses
-O_NONBLOCK.
-Swap test T5b: the direct helper test puts a `stat` shim on its own PATH. On its first call the shim
-renames another file over the slot, then runs the real stat. The helper must exit 1 and print nothing.
-Mutant M2 drops the inode compare and must fail T5b.
-
-Q2, the chief: found through `roles` by definition, not through `launch.instances`. A fire only delists
-the name (`packages/business/src/instance-settings.mjs:355`), and `roles[name]` stays. Only a delete
-removes it (`deletedDocument`, :70).
-- Gitea grant evidence for any `roles` entry whose definition is `chief-of-staff` ends the fallback.
-  That includes a fired chief beside a new listed one.
-- A live credential comes only from the listed chief's live, unheld `gitea_grants` row.
-- With no `roles` entry of that definition (deleted, or never a chief), any gitea grant event in the
-  business refuses `library-fetch-no-grant`.
-  - Cost, for Sage: row 236 lets seat gitea grants exist before C2-21. So a business with no chief
-    entry and one seat grant loses the slot fallback. That fails safe, but it narrows "an install that
-    runs before C2-21 still syncs".
-- T7's fired case also asserts that `roles[chief]` still exists after `instance.fire`.
-
-N1: the `credential` key is optional in `mirror.mjs`'s exact `keys(...)` check (:221), so a pre-286
-state file still reads. The old fixtures have no `credential`: `library-sync.test.mjs:18`,
-`library.test.mjs:106` and `mirror.test.mjs:13`. New test T12 reads a pre-286 state file. Row 224
-(Della, 23816cf28) also changes `packages/bus/src/runtime.mjs`. Whichever lands second rebases and reruns
-bus whole.
-
-N2: `[remote rejected]`, a hook refusal, is `library-push-failed`, not a race. Only `[rejected]` with
-`(fetch first)` or `(non-fast-forward)` counts as a race. The evidence query depends on
-`body.method` and `body.agent`. gitea `grant.applied` carries both at `broker.mjs:2479` and
-`grant.revoked` at :1862 and :2797. The spend event (`operation: 'grant.gitea'`, :1093) carries
-neither, so it doesn't match.
-
-N3: `fetchCredential` reads the store, so it is the bus's choice function, not a pure one.
-
-## Rulings sage-2928
-
-- Q1: Dewey's fix, in sh. On dragon-lin `/bin/sh` is bash, and GNU coreutils stat 9.11 gives
-  `stat -L -c '%d:%i %u %a %s %F' /dev/fd/3` on an open fd. Checked at 18:47Z with a scratch file, not
-  the repo. The helper runs as git's child in the bus process, not under bwrap. T5b stages the swap with
-  the PATH stat shim. If a run shows the swap can't be staged reliably, BUILD.md names M2, which drops the
-  fd compare, and it gets killed.
-- Q2: chief by `roles[*].definition === 'chief-of-staff'`. The blanket refusal applies only with no such
-  entry. Departure from the brief's "an install that runs before C2-21 still syncs", accepted in
-  sage-2928: it refuses rather than widens, and every install enrolls the chief at initial configuration
-  (F40, Q226). The refusal's message names the fix: "add the chief of staff, or grant the library
-  through C2-21".
-- N1: as above.
-
-## Build notes (code written; nothing run yet; dewey-0864 folded)
-
-Files changed:
-- `packages/library/src/sync.mjs`: `syncCommand` takes `push` with a full-sha `commit`; `push()`;
-  `humanCredential()`; `sync()` takes `credential`; `HUMAN_SLOT`, `CREDENTIAL_KINDS`. The `slot` opt
-  and `MOSAIC_LIBRARY_SLOT` keep their names and now name whichever file answers.
-- `packages/library/src/index.mjs`: the new exports.
-- `packages/library/bin/askpass`: Dewey's fd 3 check.
-- `packages/library/src/mirror.mjs`: optional `credential` in the state key check. Nothing renamed.
-- `packages/bus/src/broker.mjs`: `LIBRARY_FETCH_FIX` and `libraryFetchCredential(business)`.
-- `packages/bus/src/runtime.mjs`: `syncOptions` passes the broker's choice to the verb and the timer.
-  The timer's held line adds `fix` for `library-fetch-no-grant`.
-- `packages/library/README.md`: "Push and credentials (C2-03b)".
-- Tests: `packages/library/tests/sync.test.mjs` (appended), `packages/bus/tests/library-credential.test.mjs` (new).
-
-Choices made without a ruling. Each is small and reversible:
-- `humanCredential(context, { user, configDir })`: sage-2925 named `{user}`. The slot path needs the
-  config dir, and the library package doesn't know it, so the caller passes it. That's the same
-  source runtime's `slotDir` uses.
-- `BusError` carries only a code, so the sage-2928 fix text can't ride on the verb's refusal. It
-  goes in the timer's log line (`fix`) and in the README. The verb answers `library-fetch-no-grant`.
-- T7 and T9 run the real verbs (dewey-0864, ruled by sage-2947: no SQL staging; replaces the
-  staged state in cefebf65b). Until row 285 lands, the test passes its own definitions; once it lands
-  the real chief definition carries gitea. Whichever of 285 and 286 lands second rebases and reruns
-  library and bus whole (sage-2947). The chief's grant goes through decision.raise and the human's yes against fake-gitea-api.mjs. The test's own
-  definitions give chief-of-staff a gitea credential, as gitea-grant.test.mjs gives coder one. The
-  real roles/chief-of-staff.json has `credentials: []`, so a live chief can't get one before C2-21.
-  - Revoked: `grants.revoke`, then the row is gone and the fetch refuses.
-  - Fired: `instance.fire` can't fire the launch.by chief. Only the launch.by role calls it, and it
-    refuses its own name (`organization-instance-referenced`, broker.mjs `#chiefLifecycle`). So the
-    test's launch.by is `boss` (definition pm, the chief's authority), and boss fires the one listed
-    chief-of-staff instance. Step G deletes the row (row 281), `roles.chief` stays, the fetch refuses.
-    Only launch.by may call instance.fire (`role-not-chief`, broker.mjs:4308 at 94c33a43c) and it
-    refuses its own name (:4335), so this is the only fired chief the verb allows. Accepted by
-    sage-2951 as brief owner and read the same way in dewey-0869.
-  - T9's revoked case runs `grants.revoke` on the runtime's own data root and store, between starts.
-    T9's runtime gets a scratch roles/ whose chief-of-staff carries `{service: gitea}`, as row 285
-    ships it (case2-rows.md:1823-1824), so its definitions match the grant's (dewey-0869). After a
-    rebase onto 285 the copy needs no edit.
-  - Delisted with the row still there, a `fire.stopped` with no `fire.done`, held, two chiefs and
-    another project stay unit checks on the choice function with SQL fixtures.
-- "Another uid" in T5: the suite can't chown, so a PATH `stat` shim reports uid+1 for the open file.
-  The real `id -u` compare is covered only through that shim (dewey-0864).
-- Two listed chiefs, or none listed, refuse `library-fetch-no-grant` (T8).
-- The race fetch inside `push()` takes sync's `running` guard (dewey-0864 R1, in this row per
-  sage-2947). While a sync of the mirror runs it refuses `library-sync-busy`, fetches nothing, and
-  the caller writes again. Test: "race fetch: while a sync of the mirror runs". Its sync fetch is a
-  git alias that touches a marker, then waits for a release file. The push starts after the marker
-  exists and the release comes after the refusal, so nothing depends on timing (dewey-0869).
-- The slot at 0000: T9 covers the revoked case at runtime. Fired and held refuse inside the choice
-  function, which takes no path and opens no file. `sync` with any `{ refused }` runs no git (library
-  test, valid slot present).
-- First-run reds in the new tests are mine to fix in setup and report afterwards (mos-1272).
-- The chief's evidence is any gitea grant event naming the chief, of any action (grant.applied,
-  grant.revoked and the rest), per the plan. The spend event names no agent, so it doesn't count.
-
-Test map:
-- library sync.test.mjs: argv (push), T1, T2+T3, T4 (dead remote, hook, wrong token), refused or
-  unsafe credential runs no git, T10, fetch credential and state with N1/T12, T5+T5b.
-- library sync.test.mjs also: race fetch busy (R1).
-- bus library-credential.test.mjs: T6, T7 (real revoke and fire), T7 choice checks, T8, departure,
-  T9 runtime (real grant, chief file and user via timer and verb; real revoke, slot 0000: no git,
-  log `fix`, state `credential: null`).
-- webby-0151 R3: T9 reads `library.status` for `credential` and `lastError`.
-- T11 token search: T1 scans the data root and every file but the seat's; T9 scans the log lines.
-  The gate's output search uses the fixture tokens `fixture-token-*-made-up-00{42..49}`.
-
-Mutants (each must die on a semantic assertion):
-- M1: `+` before the push refspec in `syncCommand`. Expected to fail: the argv test, and T2 (the
-  forced push lands, so `raced` is never reported and her commit is gone).
-- M2: drop `test "$1" = "$path"` from askpass. Expected to fail: T5b (the helper prints the checked
-  file's token).

+# Row 285 build notes: C2-08b creative and chief role changes
+
+Seat: Scrooge. Reviewer: Webby. Gate owner: Sage. Issue #1790 (mos-1309 item 5).
+Brief: `docs/plans/2026-10-20_case2-rows.md` at 94c33a43c, row 285 section, gate under "### Gate".
+Base: 94c33a43c on branch `scrooge/row285`.
+
+## Status
+
+- The code, tests, fixtures and docs are written locally. No test has run. Sage's order puts row 252 first at the next CLEAR, and nothing runs during another seat's slot.
+- The Results section is empty until that run. Nothing below claims a pass.
+- Mos ruled the mos-1272 points in mos-1332 (18:55Z). mos-1333 (19:04Z) withdrew item 3, the business.mjs publish fence. See "Old tests" below.
+
+## What changes
+
+- The six creative roles (companion, ideas, research, proofreader, fact-checker, continuity):
+  - withinRole is `["message.send", "library.write"]`.
+  - credentials is `[{"service": "gitea", "scopes": ["read:user", "write:repository"]}]`.
+  - Each contract's Authority and Protocol lines describe the two library write tools, which are limited to `.md` files in supporting folders the user marked. The agent never holds a token.
+- The chief of staff:
+  - credentials is `[{"service": "gitea", "scopes": ["read:repository", "read:user"]}]`, with no library.write.
+  - The contract says the broker holds that token and it can't publish or push.
+- `vocabulary.mjs` drops CREATIVE_KINDS and adds CREATIVE_ACTIONS (`message.send`, `library.write`) and CREATIVE_SERVICE (`gitea`).
+- `role.mjs` checkCreative refuses a creative role that holds any withinRole action outside CREATIVE_ACTIONS, any crossRole action, or any credential service other than gitea.
+- `broker.mjs` #giteaRole (:2138) also refuses the chief of staff with `gitea-not-declared` (sage-2921).
+- business.mjs does not change (mos-1333 item 1). The fence added in 5f81d0da0 is removed in a later commit, so the branch's business.mjs equals the base.
+
+## Rulings
+
+- **webby-0164:** PRD 1.15 rewrites REQ-LIB-6 so creative agents write `.md` files in supporting folders. The REQ-WAIT-3 routing line is the missing piece.
+- **mos-1328:**
+  - library.write routing goes in PRD 1.16, which needs Jason's explicit yes (REQ-WAIT-2).
+  - library.write stays out of ROUTED until 1.16 lands.
+  - If Jason changes the bounds, row 285 gets a new brief.
+- **sage-2915:**
+  - The scopes a role declares must equal what any token minted for that role holds, at the commit where 285 lands.
+  - The creative scopes `["read:user","write:repository"]` are approved.
+  - The ROUTED edit gets its own commit, citing the paragraph.
+- **sage-2921:**
+  - Refuse the chief in #giteaRole, with a gitea-grant.test case next to X-G1. broker.mjs (#giteaRole only) and gitea-grant.test join the manifest.
+  - Grep the tests for the gitea-not-declared text and for pins on broker.mjs before in-review.
+  - The ROUTED commit cites 1.16 (row #1796).
+- **mos-1330:**
+  - Item 1: the fixture change gets its own commit. Only fixture data changes, and named tests cover a missing gitea ref.
+  - Item 2: option A is approved. The live chief gets one gitea ref. Every repo business writer gets the ref.
+- **sage-2937:** if Mos rules (b), business.mjs joins the files owned, scoped to the refusal near :166 and clear of :283-291 (row 287, Megavolt).
+- **webby-0174:** each changed expected value carries Mos's ruling key. The load fence needs a design line, its own test, a mutant and a grep of the tests for the N10 text.
+- **mos-1332:** the mos-1272 rulings, items 1-5, cited under "Old tests". The ROUTED commit and the landing still wait on Jason's yes on PRD 1.16 (Q32, Vikunja 546). The build, the gate and Webby's review go ahead.
+- **mos-1333:** withdraws mos-1332 item 3, since the fence contradicted the brief (:1825, :1829, :1839, and row 287's chief publish ["books"] at :1998). Items 1, 2, 4 and 5 stand.
+  - The fence leaves business.mjs in a new commit, no force-push. business.mjs leaves the manifest and its fence mutants are dropped.
+  - business.test "row 285: a creative instance with identity and publish loads" is back in its 8c529fb4d form.
+  - N10 takes option (a). See "Old tests" item 3.
+  - A new named test: a chief with its gitea ref, identity and publish ["stack"] loads.
+  - Row 287 has nothing to reshape. Its binding note below still applies.
+- **sage-2946:** the bus suite runs whole (broker.mjs is in the manifest and bus tests read roles/chief-of-staff.json), plus the cli example readers. Item 2 is answered below under "Scopes field required".
+
+## Scopes rule evidence (sage-2915 q2)
+
+At 94c33a43c, exactly one path mints a seat token. That is the Gitea grant, `broker.mjs:2420`, where `api.tokenCreate(user, tokenName)` takes the default scopes. The default is SEAT_SCOPES `['read:user', 'write:repository']` (`gitea-grant.mjs:29`, `:263`).
+
+The only other tokenCreate caller is the admin rotate (`gitea-grant.mjs:331`), which uses ADMIN_SCOPES.
+
+The creative declaration therefore equals SEAT_SCOPES. The chief's read declaration would be narrower than a minted token. #giteaRole refuses the chief, so no grant path mints the chief a token at the landing commit.
+
+### Scopes field required (sage-2946 item 2, Megavolt's question)
+
+role.mjs refuses a gitea credential entry with no scopes. `{"service": "gitea"}` goes through checkGiteaScopes (role.mjs:100-111), which calls `requireDistinctList(scopes, "gitea scopes", ..., {nonEmpty: true})`. util.mjs:42 refuses a non-array with "gitea scopes must be an array". Only a `host` entry may omit scopes (role.mjs:134). So every gitea entry names its scopes, and for a minted token they must equal SEAT_SCOPES (sage-2915).
+
+### Binding note for row 287 (C2-21)
+
+- The library read grant row must mint the chief's declared scopes (`read:repository`, `read:user`) and not SEAT_SCOPES.
+- It needs a test showing the chief's token lacks `write:repository`.
+- If it reuses #giteaRole, it has to lift the chief refusal and pass the declared scopes in the same change.
+
+## Live step (mos-1330 item 2, option A)
+
+The live dragon-lin chief holds no credentials, and there are no creative instances. After row 285 lands, the chief entry in the live business file needs one gitea reference, or the file refuses at load with "must reference exactly the services its role definition needs (gitea; got none)".
+
+Exact JSON, added to the chief instance (store form, the form the human's `instances.set` add writes):
+
+```json
+"credentials": { "gitea": { "store": true, "rotateBy": "YYYY-MM-DD" } }
+```
+
+The file form also works: `{ "gitea": { "file": "<configDir>/secrets/<business>/chief-of-staff-gitea.token", "rotateBy": "YYYY-MM-DD" } }`. That file must exist, mode 0600.
+
+- The reference creates no account, mints no token and grants nothing by itself.
+- The window owner adds it after a backup of the business file, and before P3.
+- **Precondition for the store form:** the store root `<configDir>/secrets/agents` must exist and be private, since `bus/src/credentials.mjs:212` calls privateDir on it when the reference is read.
+
+## Repo business writers (mos-1330 item 2)
+
+A git grep of scripts, templates, src, tools and packages outside tests found two repo files that write a business file with a chief. Both get the gitea file reference:
+
+- `packages/business/examples/mosaic-stack.example.json:114`, the chief entry. Two test files read it (corrected after webby-0178 B2):
+  - `packages/business/tests/business.test.mjs:256`, "the shipped example refuses as written and validates once filled in". It replaces `/home/you` with its tmp root and checks the role list and the sync token path. The chief's new file ref goes through the same replacement.
+  - `packages/cli/tests/stack-release-fixture.mjs:351` (EXAMPLE, through `biz()`). It fills botId and the dates but keeps the `/home/you` token paths, as it already does for the other roles' refs. Its readers are stack-release.test, stack-release-external.test and stack-upgrade.test.
+  - All four test files run whole at the gate.
+- `packages/business/README.md:174`, the chief example line, plus the prose at :163 and :183 that said the chief holds no credentials.
+
+No script, template or case installer writes a chief or creative instance. `scripts/case1-accept.sh` only talks to `chief`.
+
+## Fixture changes (mos-1330 item 1, own commit)
+
+Data only, with one named exception listed under "Old tests".
+
+- `packages/business/tests/helpers.mjs:71-74`
+  - Old: `// The chief of staff launches (REQ-LAUNCH-1, decision 139); it holds no` / `// credential and no tracker bot.` / `chief: { definition: "chief-of-staff" },`
+  - New: `// The chief of staff launches (REQ-LAUNCH-1, decision 139); it has no` / `// tracker bot. Its one credential reference is gitea, for the library` / `// read grant (row 285, mos-1330).` / `chief: { definition: "chief-of-staff", credentials: { gitea: ref("chief-of-staff", "gitea") } },`
+- Creative and chief instances loaded through the loader each gain `credentials: { gitea: { store: true, rotateBy: FAR_DATE } }`, and the import adds FAR_DATE where needed:
+  - `packages/business/tests/instance-settings.test.mjs:334`, `:335`, `:380` (import :12)
+  - `packages/business/tests/lifecycle-settings.test.mjs:237` (import :11)
+  - `packages/business/tests/launch-settings.test.mjs:184`, bean (FAR_DATE already imported)
+  - `packages/business/tests/resolve.test.mjs:117`, chief2 (import :7)
+  - `packages/bus/tests/creative.test.mjs:98`, bean in the written business file (import :10). The `startBroker` businesses object at :111 doesn't go through the loader and is unchanged.
+  - `packages/cli/tests/launcher.test.mjs:769`, bean (import :1)
+- `packages/business/tests/business.test.mjs`: the persona test's bean fixtures get `credentials: CREATIVE_GITEA` (4 places).
+
+New named tests (mos-1330 item 1):
+
+- business.test "row 285: a chief or creative instance without credentials.gitea refuses at load". Each case refuses with the checkCredentialMap "(gitea; got none)" message, and a positive control loads.
+- business.test "row 285: a creative instance with identity and publish loads" (brief :1825, :1839, restored by mos-1333 item 2). The grant still refuses it at raise (#giteaRole).
+- agent-identity.test "row 285: a chief with its gitea reference, identity and publish loads" (mos-1333 item 4, brief :1829). It also checks the chief's credentials are exactly gitea.
+
+## Old tests (mos-1272, ruled in mos-1332 and mos-1333)
+
+Webby (webby-0174) passes each item only with Mos's ruling key next to it.
+
+1. **`packages/business/tests/chief-of-staff.test.mjs`** (mos-1332 item 1, accepted as pushed). Expected values follow the role file:
+   - APPROVED.credentials (:24). Old: `[]`. New: `[{service: "gitea", scopes: ["read:repository", "read:user"]}]`.
+   - The resolved-record test (:90). Old: `{}`. New: `{gitea: {service: "gitea", file: <root>/secrets/chief-of-staff-gitea.token, rotateBy: FAR_DATE}}`.
+   - :155. Old name: "the instance takes no credential references and no tracker", expecting "(none; got gitea)". New name: "the instance takes only the gitea credential reference and no tracker", adding a vikunja ref and expecting "(gitea; got gitea, vikunja)". The tracker refusal is unchanged.
+2. **`packages/business/tests/role.test.mjs`** (mos-1332 item 2, accepted). checkCreative checks the service and not the scopes (webby-0178 N1). The scopes are pinned by the load test, which deepEquals each of the six creative role files' credentials to `[{service: "gitea", scopes: ["read:user", "write:repository"]}]`, so a widened scope in any one file is red.
+   - The six-creative-roles load test now pins withinRole `[message.send, library.write]` and credentials `[{gitea, [read:user, write:repository]}]` exactly. Old: `[message.send]` and `[]`.
+   - The M1 block checked record.write and one crossRole case. It now loops over every routed action outside CREATIVE_ACTIONS, keeps the crossRole refusal, and adds the vikunja and host credential refusals. The refusal text changes from "may hold only withinRole message.send" to "may hold only withinRole message.send and library.write".
+3. **`packages/business/tests/agent-identity.test.mjs:49-50` (N10)** (mos-1333 item 3, option (a); replaces mos-1332 item 3). After 285 the chief's definition declares gitea, so the old second case no longer refuses. Only the fixture instance and the instance name in the regex change. The text after the name is unchanged.
+   - Old: `refuses(() => check((d) => { d.roles.chief.identity = structuredClone(IDENTITY); d.roles.chief.publish = ["stack"]; }),` / `/roles\.chief\.publish needs identity and a gitea definition/);`
+   - New: `refuses(() => check((d) => { d.roles.helper = { definition: "assistant", holder: "mos", identity: structuredClone(IDENTITY), publish: ["stack"] }; }),` / `/roles\.helper\.publish needs identity and a gitea definition/);`
+   - The standalone helper test added in 5f81d0da0 is removed. The fence and its business.test change are reverted.
+   - Grep of `packages/*/tests/*` for "needs identity and a gitea definition": only agent-identity.test :47, :48 and :52. No other reader.
+   - Mutant M9 below.
+4. **`packages/business/tests/instance-settings.test.mjs:289`** (mos-1332 item 4, accepted). Old: `{ services: [], accepted: true }`. New: `{ services: ["gitea"], accepted: true }`. If the :298 listing changes at the run, the exact new value goes here and Webby hears about it. Anything that removes or weakens a check goes back to Mos.
+5. **Other fixture edits** (mos-1332 item 5): data only, no ruling needed.
+
+## Commit plan
+
+1. Role files, contracts, vocabulary, role.mjs, broker #giteaRole, gitea-grant.test and role.test, plus this file.
+2a. The mos-1332 commit (5f81d0da0): instance-settings.test:289 and this file. Its business.mjs fence and two fence tests are reverted by the mos-1333 commit.
+2b. The webby-0178 commit (d79cfe674): B1, B2 and notes.
+2c. The mos-1333 commit: the fence removed, business.test restored, N10 option (a), the named chief test and this file.
+2. The fixture commit (mos-1330): helpers.mjs, chief-of-staff.test, business.test (fixture refs and the two new named tests), the loader fixtures above, the example json and README. Mos ruled the old-test points in mos-1332.
+3. The 1.16 commit: `library.write` in ACTIONS and ROUTED in both `business/src/vocabulary.mjs` and `bus/src/broker.mjs`, citing the PRD 1.16 paragraph (row #1796), with a hard-waits test that it is routed. It's held until Jason's yes and 1.16 lands.
+
+Until commit 3, every creative role file refuses at load (REQ-WAIT-2: a GATED_ONLY action in a role file). The branch is green only with all three commits.
+
+## Mutant plan
+
+Kill rules are written before the runs. Each mutant is one edit, then a restore, a sha256 compare and a clean `git status`.
+
+| M | Mutant | Source | Expected kill |
+|---|---|---|---|
+| M1 | drop `role.definition === STAFF_TO` from #giteaRole | broker.mjs:2138 | gitea-grant.test "X-G1: the chief of staff refuses at raise" |
+| M2 | CREATIVE_ACTIONS gains `role.end` | vocabulary.mjs | role.test M1 routed-action loop |
+| M3 | drop the creative services check | role.mjs checkCreative | role.test M1 vikunja and host refusals |
+| M4 | drop the crossRole check | role.mjs checkCreative | role.test M1 crossRole refusals |
+| M5 | creative role file without library.write | roles/companion.json | role.test creative-load test |
+| M6 | chief scopes widened with write:repository | roles/chief-of-staff.json | chief-of-staff.test "the shipped file is exactly the approved list" |
+| M9 | drop `\|\| !services.includes("gitea")` from the N10 check | business.mjs:166 | agent-identity.test N10's helper case :51-52 (mos-1333 item 5) |
+
+M7 and M8 targeted the withdrawn fence and are dropped (mos-1333 item 1). M9 mutates a file outside the manifest only to show the N10 test still guards it.

+- Run business.test, stack-release.test, stack-release-external.test and stack-upgrade.test whole, since they read the example json (webby-0178 B2).
+- Run the bus suite whole (sage-2946 item 1): broker.mjs is in the manifest, and these bus tests read roles/chief-of-staff.json by name: chief-of-staff, fire-revokes-grants, host-run, instances-verb, names, reload, routes-verb. Sage listed five. A git grep finds the seven.
+- Run each fixture-importing suite whole: the business suite, the bus suite, the cli suite, `scripts/test-config.sh` and every `scripts/test-*.sh`, with TMPDIR under /mnt/storage/scratch/tmp.
+- Sage confirms the result against mos-1309 item 5.

@@ -180,45 +180,6 @@ and `library.status` shows the result once it ends. A sync that outlasts the 120
 `request-timeout` from the server and still finishes the same way. The Console has no library route yet: `cli.mjs`
 passes `librarySync` to `startServer`, and `serve.mjs` doesn't read it.
 
-### Push and credentials (C2-03b)
-
-`push(context, { commit, credential, retried })` sends a full commit id, already in the mirror, to the
-entry's `branch` as `push --porcelain --no-verify --no-follow-tags --end-of-options <url>
-<commit>:refs/heads/<branch>`, through the same prefix, env and helper as the fetch. The refspec has no
-`+`, so the remote takes a fast-forward only.
-
-| git says | Answer |
-|---|---|
-| the push landed | `{ pushed: true }` |
-| `[rejected] (fetch first)` or `(non-fast-forward)` | one fetch with the same credential, then `{ pushed: false, raced: true, tip }` |
-| the same, with `retried: true` | `stale-base` |
-| the same, while a sync of the mirror runs | `library-sync-busy`, with no fetch |
-| anything else, `[remote rejected]` (a hook) included | `library-push-failed` |
-
-Push moves no local ref; C2-02 re-applies and moves `served`. git's output is never kept.
-
-A credential is `{ kind, user, file }`, with `kind` one of `slot`, `chief`, `seat` or `human`, or the
-bus's `{ refused: code }`. The helper reads only `file`. It opens the file on fd 3 and refuses unless
-the open file and the path have the same device and inode, and the file is regular, the bus's uid's,
-mode 0600 and at most 16384 bytes, as `readSecretFile` in `packages/bus/src/gitea-grant.mjs` checks a
-grant store file. A FIFO swapped in after `test -f` blocks the open, the same residual
-`readSecretFile` has.
-
-- A seat writes with its own Gitea user and grant store file, `<storeRoot>/<business>/<agent>/gitea`.
-- `humanCredential(context, { user, configDir })` gives her save its credential: her Gitea login and
-  `<configDir>/secrets/<business>/library-human`. A missing login, or a slot that is missing, a link,
-  another uid's or not 0600, refuses `library-human-missing` before any git call.
-- The fetch takes the broker's choice, `libraryFetchCredential(business)`. The chief is a `roles`
-  entry whose definition is `chief-of-staff`; a fire keeps it there. With no Gitea grant evidence for
-  a chief, the fetch uses slot `library-gitea` and the entry's `user`. Once there is some, only the one
-  listed chief's live, unheld grant answers, with that grant's user and store file. Anything else
-  refuses `library-fetch-no-grant`, and so does any Gitea grant evidence in a business with no chief
-  entry. That refusal opens no file and runs no git. The bus answers its code; the timer's log line
-  adds `fix: "add the chief of staff, or grant the library through C2-21"`.
-
-The sync state adds `credential`, `{ kind, user }` of the last fetch, or `null` when none ran. It is
-optional, so a state written before C2-03b still reads.
