+# 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.
+- Three mos-1272 points are open with Mos (scrooge-285-oldtests-mos-1, 18:51Z). 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).
+
+## 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.
+
+## 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.
+
+### 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. No test reads this file.
+- `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".
+
+## Old tests (mos-1272, open with Mos)
+
+Webby (webby-0174) passes each item below only with Mos's explicit mos-1272 ruling key next to it. Each key reads "pending" until Mos rules (asked in scrooge-285-oldtests-mos-1).
+
+
+1. **`packages/business/tests/chief-of-staff.test.mjs`** (ruling: pending). Two expected values follow the role file:
+   - APPROVED.credentials (:24) is now `[{service: "gitea", scopes: ["read:repository", "read:user"]}]`.
+   - The resolved-record test (:90) expects `{gitea: {service: "gitea", file: <root>/secrets/chief-of-staff-gitea.token, rotateBy: FAR_DATE}}` where it expected `{}`.
+   - :155 was "the instance takes no credential references and no tracker", expecting "(none; got gitea)". It is now "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/agent-identity.test.mjs:49-50` (N10)** (ruling: pending) is expected red. A chief with identity and publish now loads, because its definition declares gitea. Options sent to Mos:
+   - (a) Switch the case to an instance whose definition has no gitea.
+   - (b), recommended: business.mjs:166 also refuses publish for a chief-of-staff definition, and the test stays unchanged.
+     - Sage (sage-2937) put business.mjs in 285's files owned, scoped to this refusal near :166 and kept out of :283-291, which row 287 (Megavolt) owns.
+     - Webby (webby-0174) treats it as a product change. It needs a design line, its own test, a grep of packages/*/tests for the old N10 text, a mutant, and a BUILD.md line citing Mos's ruling.
+     - Design line, if Mos rules (b): a chief-of-staff instance that names `publish` refuses at load with the N10 message. Its gitea is a read grant only (sage-2915), so it never publishes. This fences the same case #giteaRole refuses at raise, one step earlier.
+3. **`packages/business/tests/instance-settings.test.mjs:289`** (ruling: pending) is expected red. Old: `{ services: [], accepted: true }`. New: `{ services: ["gitea"], accepted: true }`. In short, `view.definitions.companion` becomes `{services: ["gitea"], accepted: true}`. The listing at :298 is checked at the run.
+
+## Commit plan
+
+1. Role files, contracts, vocabulary, role.mjs, broker #giteaRole, gitea-grant.test and role.test, plus 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. It doesn't land until Mos rules the old-test points.
+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" |
