-## 2026-10-23 — Row 288 C2-02 build starts (Bubba, #1793)
-
-Before: agents can read the library; supporting-path and push-credential dependencies are separate unlanded heads. After intended: per-seat supporting writes/deletes with exact notices, human revert and one commit per Console save. Work is on bubba/row288, chained on original 283/285/286 commits; 284 tool base still pending. Plan and acceptance evidence: agents/bubba/work/queue-288/BUILD.md. Untested; no Node/test/build/gate run before Sage CLEAR. Landing waits for every dependency's own gate.

-# Row 288 (#1793): C2-02 agent writes, notices, revert and Console saves
-
-Owner: Bubba, Codex gpt-6.1-sol, thread 3d6672b5-5544-4b95-9e09-e79574f1aa14.
-Reviewer: Webby. Gate and landing: Sage. Append-only build record.
-
-## 2026-10-23 start and implementation plan
-
-Base 45dca69f6 on bubba/row288. Direct mandate mos-1499 (Q245), confirmed sage-3613.
-The canonical `scripts/mosaic queue next bubba` returned `nothing`; Sage owns the owner transition.
-The initial worktree invocation refused linked-worktree use; retried in canonical checkout.
-
-Spec: docs/plans/2026-10-20_case2-rows.md, C2-02; agents/gosalyn/work/case2/DESIGN.md ruling after r11.
-Handoffs: Honker queue-283 BUILD.md Q4 (missing/non-100644 delete refuses); Morgana
-queue-225 BUILD.md A2 at 66f7becf2 (strict revert arguments/result), confirmed by Fethry fethry-0005.
-`project` is the business.projects key, never a chat UUID.
-
-Dependencies merged with their commits intact, no amend or force-push:
-- 283 origin/honker/row283-build 88ec5e8e4 (new E4 head to follow).
-- 285 origin/scrooge/row285-r2 53db6b7ca.
-- 286 origin/ludwig/row286-r2 573fa0be0.
-- 284: no named remote branch yet. Tool changes come last.
-All merge commits are marked Untested. Nothing has run under Node. Sage's latest instruction
-sage-3613 reserves **all Node and test runs** for CLEAR; this supersedes the initial targeted-test
-permission. Build untested now as instructed, then run RED/GREEN checks/mutants on CLEAR.
-
-Architecture: one host-only plumbing writer under the existing library lock; broker authorizes and
-selects credentials, then inserts the fixed notice directly. Human save/revert use editor +
-library-human independently of seat lifecycle. No worktree, deferred push, role expansion or UI.
-
-### Tasks and acceptance
-
-- [ ] Plumbing: new library/src/write.mjs, mirror state publication and package exports; new
-  library/tests/write.test.mjs. One-parent write/delete, byte-exact content, seat identity/trailer,
-  stale-base, nonregular/missing deletes, retry once on an unrelated remote change, push failure
-  without local ref movement, human editor and revert reachability/single-path checks.
-- [ ] Broker + runtime: library.doc.write/delete, library.file.save, library.revert; strict keys,
-  creative + library.write + live unheld project grant; direct exact notice; human-only save/revert.
-  New bus/tests/library-write.test.mjs covers authorization, unchanged refs, A2 contract and socket.
-- [ ] Transport: only human library.file.save joins the existing large-save exception. New tests
-  prove >64 KiB save accepted, agent writes retain 64 KiB bound, malformed/oversize saves refuse.
-- [ ] Tools after 284: library_doc_write/delete in harness tools; exact eight/ten-name snapshots
-  in a new harness test; cli dispatch wiring.
-- [ ] Verify on CLEAR: new tests, library/bus/harness suites and all scripts/test-*.sh on Sage's
-  assigned slot. Mutants remove supporting guard and force push; both must fail. Fixture-token
-  search over captured output. No gate, landing or queue move claimed before Sage's acceptance.
-
-Pre-flight interfaces: broker consumes library writer {project,path,commit}; revert adds reverted;
-writer consumes C2-03b push {pushed} or {raced,tip} and supportingPath(mapping,universe,path,tree).
-State publication must add optional lastPush while preserving old state readability. Refusals must
-restore fetched remote-tracking refs as well as preserve served. Runtime must bind credential file
-references itself; no file, identity, message or credential is supplied by the agent.
-
-Necessary file-scope additions: packages/bus/src/runtime.mjs (actual adapter injection),
-packages/library/src/index.mjs (exports), and CLI's existing console adapter if saves require it.
-Reported to Sage in bubba-0002. Existing tests will not be edited without Mos's OK via Sage.
-
-Review focus: remote tip races, nonregular entries and folded paths, unsafe human credential before
-git, revert after revoked/fired writer, and large-request exception never extending agent writes.
-
-### Existing-test changes
-
-None authored by Bubba yet. Dependency test changes remain their owners' original commits.
-
-## 2026-10-23 first static build (not a gate result)
-
-283 E4 merged intact at 76d651dba. Honker next reports e67c27b32 (test environment only), to merge
-before push. Della reports row 284 has not been built/pushed; row224's 23816cf28 is not a 284 head.
-No speculative 284 pin. Typed tools and served-blob lookup integration remain pending 284.
-
-Implemented (unrun): bare plumbing writer, one-parent commit and fixed trailer, exact-content blobs,
-base comparison, supporting path guard and delete regular-blob check, one remote-race retry,
-ref restoration on refusal, immediate served publication/lastPush; human save and reachable one-path
-business-trailer revert; broker grants/identity/notice path; runtime adapter wiring; large-save socket
-exception. New tests: library/tests/write.test.mjs and bus/tests/library-write.test.mjs. No old test edits.
-
-### Approved scope additions, sage-3628
-
-Every hunk outside the brief's owned list:
-- `packages/bus/src/runtime.mjs`: `humanWriteOptions` checks editor before choosing the human slot;
-  three library adapter entries bind dataRoot, command and the host-only seat store reference. These
-  are needed to make actual bus calls reach the new writer without accepting agent-supplied files.
-- `packages/library/src/index.mjs`: export writeLibraryDoc/saveLibraryFile/revertLibraryCommit so
-  runtime's existing library module adapter can call them.
-- `packages/library/src/sync.mjs`: shared write guard with opaque token compared by identity;
-  push's race fetch recognizes only that owner and does not clear its guard; ordinary sync and a
-  forged token still refuse library-sync-busy. Narrow publishLibraryWrite validates ids, reads the
-  locked state, rebuilds the index via readLibrary, moves served/tracking and writes lastPush. The
-  raw writeState remains private and is not exported through index.mjs.
-
-Ludwig ludwig-0064 reviewed the intended interface and requested the opaque token (implemented),
-narrow publication (implemented), whole library + bus library-credential checks and a token mutant
-(planned). His 573fa0be0 remains current and unrun. 288's additions are separate commits, not folded
-into 286. Tracking restores only if the whole write refuses, not between the first race and retry.
-
-Known tradeoff, accepted by Sage sage-3628 for MVP: the brief holds the flock through network Git;
-readers can hit the existing 5-second library-sync-busy while it runs. Structural supportingPath
-preflight is pure and precedes Git; served/fetched listTree checks repeat it with the real tree before
-any remote write. A tree-dependent check necessarily reads the tree first (Honker honker-0184 item2).
-
-### Mutants for CLEAR
-
-- Remove the `pathOf` calls for agent operations: the M12 broker/bare-ref tests must fail on a
-  story/unsupported path while checking remote, tracking and served refs.
-- Prefix the push refspec in syncCommand with `+`: write.test moved-target race must fail, because
-  its command seam preserves production syncCommand's refspec (only remote URL/protocol are fixture).
-- Replace `writers.get(mirror) === writeToken` with `true`: write.test forged-token case must fail.
-
-No Node, test, build or mutant has run. `git diff --check` is clean. Counts are not claimed.
-
-### Console dispatch integration
-
-The existing cli delegates its transport wiring to console-bus.mjs, so the save dispatch needs that
-file too: one null `librarySave` option and one `--send` assignment to library.file.save. cli.mjs
-threads that option into startServer; row C2-11b owns the actual route/page that consumes it. New
-webui/tests/library-write-options.test.mjs covers --send and the user transport boundary. 225 owns
-libraryRevert dispatch; 288 adds only librarySave to avoid overlapping that ownership. Additional
-scope reported to Sage and Fethry. No changes to an existing test.
-
-## 2026-10-23 second static pass and dependency review
-
-First push: c867cada9 on origin/bubba/row288, reported bubba-0005 to Sage/Webby/Mos and
-bubba-0006 to Fethry/Ludwig. No PR created and no review/gate requested as complete.
-
-Ludwig ludwig-0065 checked the exact sync diff against 286 without running anything. Token identity,
-ordinary-sync exclusion, 286 R1 preservation, guard key and end-of-write tracking restoration fit.
-F1: state publication could fail after served moved, leaving old state/new served. Root cause is
-publication order without rollback, compared against sync's existing rollback. Added an unrun
-filesystem rename-failure regression, then changed the narrow helper: on failure it validates the
-state under the same lock, CAS-restoring served if state has not published the new commit. If rename
-succeeded but directory fsync failed and the state validates against new served, it keeps that pair.
-All failure cases answer outcome-unknown; tracking remains the commit already pushed remotely.
-Verification is pending CLEAR, so this is a proposed fix, not a tested resolution.
-
-Added the actual broker-to-bare tests for each M12 path refusal (both agent verbs), unchanged remote
-and all mirror refs, exact write/delete notices, and human revert after fixture grant removal/hold.
-The bare fixture moved to new library/tests/write-fixture.mjs so broker tests reuse real plumbing.
-Added the raw socket proof-nested-save-name case to pin the parsed-verb large-request check.
-Missing editor/slot tests now make the mirror metadata invalid first: reaching Git would change the
-refusal, so the tests check the pre-Git gate rather than merely count remote commands.
-
-Additional required doc hunk: packages/library/README.md appends the four verb contracts,
-lastPush shape, exact notice, lock tradeoff and publication failure behavior. No existing test from
-the dependency/base has changed. All new/modified tests in this pass were authored by this row.
-`git diff --check` remains clean. No Node/tests/build/mutants run; 284 and CLEAR remain pending.
-
-## 2026-10-23 early review follow-up (Webby E1-E6; Ludwig F2)
-
-Sage sage-3652 approves console-bus.mjs wiring (null option + --send dispatch), confirms editor.user
-as the sole human login source and reserves CLEAR for T3/T4 after T2. Ordinary sync()'s separate
-post-rename fsync gap stays out of 288 per that ruling; no change to sync()'s existing rollback.
-
-Honker 283 head 46bad7ea3 merged intact: mapping editor.user is optional, and if present uses the
-existing plain Gitea-user pattern. The omission at mapping level is valid; human writes refuse it.
-
-- Ludwig F2 / Webby E6: confirmed the previous runtime used the fetch bot's mapping.user wrongly.
-  Runtime now passes mapping.editor.user to humanCredential, never mapping.user. Missing user gives
-  library-human-missing before Git. New real-runtime cases pin both save and revert with a separate
-  fetch-bot login, positive pushes under her-gitea-login, and no command for an absent editor login.
-  The broker's credential.agent is s.role, not args: added an exact assertion and strict-key refusal
-  cases for caller-supplied agent and credential.
-- E1: replaced the business-id RegExp interpolation with a literal startsWith(business.id + '/')
-  check and ID_PATTERN on only the instance suffix. New acme.co vs acme-co trailer test.
-- E2: new broker→bare case holds the seat in the fetch command. beforePush must refuse
-  library-write-no-grant with all local refs and the remote unchanged and no notice. New mutant:
-  remove `options.beforePush?.();` in write.mjs; the E2 test must fail.
-- E3: new broker cases for expired rotate_by, fire.stopped without fire.done, missing role.publish
-  project, grant/identity Gitea-user mismatch, and missing identity name/email, for both agent verbs.
-- E4: the exceptional publication failure currently returns outcome-unknown before the broker has
-  a successful result to put in a notice, so a remote agent commit can exist without a Console
-  notice. There is no durable notice outbox/retry in this row. The trailer commit remains human
-  revertible by id after sync; this is an explicit known failure-mode gap for the manifest, not
-  a claim that every failed publication emits a notice. A new real-push test breaks state decoding
-  after push admission, pins outcome-unknown, old served and no notice. It also found a local error
-  propagation gap: errors before publishLibraryWrite's internal try now normalize to outcome-unknown
-  in the writer once push has succeeded, so the caller is never told an ordinary refused-write code.
-- E5: 284 still has no build. Tools/8-or-10 snapshot and served-blob integration remain pending.
-  librarySave is intentionally only an adapter option until C2-11b supplies its route/page.
-
-All tests above are newly authored by row288 and remain unrun; no changes to baseline/dependency
-tests. RED/GREEN and mutants await CLEAR. Proposed fixes are not claimed verified. The new host-only
-library write module imports the existing pure ID_PATTERN to match the broker's accepted instance ids.
-
-## 2026-10-23 mos-1520 ruling: post-push notice is required
-
-Correction to the E4 interpretation above: Mos rejected the known-gap treatment. The requirement
-stays: a pushed agent commit has the exact notice even if local publication then fails. This is not
-an outbox or retry. The writer now calls the broker's trusted synchronous onPushed callback as soon
-as push returns pushed:true, before publication. The callback records the exact library-write notice
-and action.allowed in the normal Console-store transaction. Publication failure still answers
-outcome-unknown. The notice's Revert can refuse library-revert-not-agent until sync makes that commit
-reachable from served; README now says that explicitly and removes the rejected gap description.
-
-The row's own real-push corruption test now pins the exact notice body with the pushed id, old
-served and outcome-unknown; after restoring readable state it pins Revert's refusal before sync and
-success after sync. The successful-write adapter fixture calls onPushed too, matching runtime's
-writer contract. No existing baseline/dependency test changed (mos-1520 explicitly authorizes this
-row's test correction without mos-1272).
-
-Residual Console-store failure: if notice insertion/routing/its event transaction fails, the broker
-calls a separate host log sink with {event:library-notice-store-failed,code:outcome-unknown,business,
-instance,op,commit}. It logs no args, path content, credential, raw SQL or exception output. Runtime's
-new library.log adapter writes this metadata to stderr. The caller gets outcome-unknown even if
-recording action.refused in that same broken store fails. A new real-push test uses temporary SQLite
-abort triggers on notice insertion and refusal evidence, checks remote advanced/served unchanged,
-no message, the exact external log and outcome-unknown. It does not claim a notice can be stored in
-a failed Console store. If the host log sink itself also fails, no durable log can be promised; the
-caller still receives outcome-unknown. The runtime log hunk is the required residual-failure wiring.
-
-Mutant added: move `options.onPushed?.({ project: context.project, path: change.path, commit });`
-from before `await publishLibraryWrite(...)` to immediately after that await inside the same try.
-Successful operations keep their notice, but the outcome-unknown publication path drops it. The
-C2-02 E4 real-push corruption test must fail on its exact notice assertion. Run on CLEAR and restore.
-
-No Node/tests/build/mutants run. Static git diff --check clean. Della's first284 head0ed4fbab9 is
-explicitly incomplete and not a finished dependency; waiting for her complete-head pin before tools.
-
-Webby webby-0253 (static, cef503cb9) closes E4 per mos-1520; no tests ran. N1: a failed notice insert throws from onPushed before publication, so served stays at the prior commit until sync; the store-failure test pins this safe direction. Only E5 (284 tools/snapshot integration) remains open in this early review.
-
-## 2026-10-23 complete284 merge and final tool integration (unrun)
-
-Della della-0037 supplied complete untested head47db04eba85ac3ceb7e81385603f97bb6f8c1a38,
-replacing the incomplete head. Merged intact as c0ca3894c. Its22423816cf28 and2164f3fbc25a
-lineage is retained. Three conflicts were in overlapping production wiring only:
-- broker.mjs: keep Della's LIBRARY_LOOKUPS object and #requestLibraryLookup byte-for-byte, and
-  keep288 writer/notice methods; LIBRARY_VERBS contains both sets and request dispatch calls lookup.
-- runtime.mjs: keep lookup adapter plus288's metadata log and write adapters.
-- library/index.mjs: keep index/query exports,286's push/humanCredential exports and288's writer exports.
-No dependency test body was changed in the merge. These are overlapping consumer integrations,
-not rewrites of dependency commits. Every prerequisite still needs its own gate (mos-1351).
-
-Added library_doc_write/library_doc_delete after the five lookups, only for a creative definition
-with a within-role library.write grant and library enabled. Closed schemas carry exactly
-{universe,path,base,content} and {universe,path,base}; base is string-or-null with 40-lowercase-hex
-pattern. No project, business, author, credential, commit or message. tools.action is library.write.
-New harness/tests/library-write-tools.test.mjs pins per-role eight/ten names, both schema invariants,
-no repo/commit/business/accept, exact required/verb/action, nullable base, and missing library/grant
-or noncreative exclusion. This satisfies sage-3678 and mos-1523's replacement coverage condition.
-
-Publication's narrow helper now calls indexFor for the new served commit instead of only readLibrary,
-so the284 lookup index is rebuilt before publication. New broker integration uses library.get's
-served blob as write/delete base, independently checks served:path, reads the new text/blob immediately,
-preserves default-canon null, then sees null after delete. No change to284's query behavior.
-
-### Authorized baseline-test migration, own commit (mos-1523 via sage-3677)
-
-File: packages/harness/tests/library-tools.test.mjs. Numstat: +4/-4, exactly.
-The noncreative LOOKUPS assertion at :33 is unchanged. Every existing lookup schema assertion stays.
-The four old/new lines are:
-
-```diff
--  ? ['web_search', 'web_fetch'] : []), ...LOOKUPS];
-+  ? ['web_search', 'web_fetch'] : []), ...LOOKUPS, 'library_doc_write', 'library_doc_delete'];
--test('M3: per-role snapshots contain six names, or eight with the C2-08 web grant', t => {
-+test('M3: per-role snapshots contain eight names, or ten with the C2-08 web grant', t => {
--  for (const [i, tool] of tools.filter(t => t.name.startsWith('library_')).entries()) {
-+  for (const [i, tool] of tools.filter(t => LOOKUPS.includes(t.name)).entries()) {
--  assert.deepEqual(tools.map(t => t.name), ['send_message', ...LOOKUPS]);
-+  assert.deepEqual(tools.map(t => t.name), ['send_message', ...LOOKUPS, 'library_doc_write', 'library_doc_delete']);
-```
-
-Additional schema mutant (mos-1523): add `commit: str("caller commit")` to writeBase in tools.mjs,
-thereby adding it to either/both write schemas. The new-file schema test must fail both its exact
-property set and forbidden-property assertions. Run on CLEAR and restore. No further assertion
-change in library-tools.test.mjs is authorized or made.
-
-All code/tests/mutants remain unrun. No Node, build or syntax check before Sage's named CLEAR.
-Static diff --check is clean. Scope additions stay listed above, now including indexFor import and
-call in the previously approved narrow publication helper. E5 implementation is present; review and
-acceptance are pending evidence, not claimed complete.
-
-## 2026-10-23 testing and landing boundary (sage-3682)
-
-Latest complete dependency2845d587a552 (test/docs only over47db04eba) merged intact as f8f79ea2f.
-Own tool implementation cd2f50dae and separate mos-1523 migration29455c0c5 are pushed; Webby reads
-E5 and Dewey checks the migration. Static manifest-r1 covered21 own paths at f8f79ea2f.
-
-Sage reserves first focused runs/RED-GREEN/mutants for T7, provisionally about22:25Z, unless he
-explicitly frees an earlier lane. No Node before his CLEAR. This is a schedule, not CLEAR. Full
-library/bus/harness and shell gates still need their own authorized slot; no gate result is claimed.
-
-Before the gate, incorporate landed refactor after283/224/284 land while preserving every
-prerequisite. Under the standing add-commits/no-force-push rule, update this published branch by merge
-rather than rewriting its pushed history. 288 lands last in the chain; no landing is authorized here.
-
-## 2026-10-23 E5 static closure and N2 wording
-
-Dewey dewey-0948: the mos-1523 migration at29455c0c5 is static CLEAN, exactly+4/-4, with the
-noncreative assertion unchanged and new-file schema coverage meeting every condition. Webby
-webby-0263: E5 closed on29455c0c5/cd2f50dae (f8f79ea2f;98ca25ab1 only BUILD.md), nothing blocking.
-Both ran nothing; Webby did not read the scratch manifest, so no manifest verification is implied.
-
-Webby N2: delete inherited the write base description "or null to create". Delete now overrides only
-that description: "The existing file's blob from library_get; a missing file cannot be deleted".
-The reviewed nullable-base schema/required keys/verbs remain unchanged. The row's new schema test
-pins create wording only on write and existing-file wording without create on delete. No further
-assertion change in the baseline library-tools.test.mjs. No Node/tests run; still await Sage CLEAR.
-
-## 2026-10-23 dependency283 follow-up (honker-0195)
-
-Merged origin/honker/row283-build b2a1f4092 intact, fast-forward lineage from46bad7ea3. It changes
-supporting.test's helper and Honker's BUILD receipts only; no production source changed. Honker
-reports library98/98, business231/231 and14/14 mutants killed on that dependency head. Those are
-his dependency receipts, not verification of288's combined branch. No288 Node/tests run; Sage's
-CLEAR is still required. The dependency's own gate/landing remains Sage's responsibility.
-
-## 2026-10-23 new candidate after283 landing (sage-3727, honker-0200)
-
-Created bubba/row288-r2 from the preserved published bubba/row2887c53adf10, then rebased with
---rebase-merges --no-update-refs onto93694c5185d0a7f989d2fe78fb620e44599b744e. This supersedes
-the earlier merge-only refresh plan for this candidate: Sage explicitly requested a fresh branch,
-not a force-push. Both local and remote bubba/row288 remain7c53adf10, unchanged.
-
-Git skipped12 duplicate283 commits already replayed upstream. Range-diff of
-45dca69f6..bubba/row288 against93694c518..bubba/row288-r2 (before this receipt) has35 equal
-commits,12 dropped,0 modified,0 added. Full output: scratch/bubba-row288/rebase-r2-range-diff.txt
-under /mnt/storage. The other prerequisite commits retain their patches; row216/224 identities are
-unchanged where Git could retain them. This is not new verification of any prerequisite.
-
-Replayed merges had the same launcher-footer and broker/runtime/index conflicts as before. Reused
-the exact previously reviewed combined file bytes, keeping both launcher test bodies and all lookup
-and writer paths. Static comparison before this receipt: all21 own manifest paths byte-identical
-to7c53adf10; all16 other changed paths exactly match93694c518 upstream. These include newly landed
-226 and coordination/docs changes already on that base, not new288 edits. No baseline assertion or
-production change was introduced by conflict resolution.
-
-Sage's base93694c518 is an ancestor of the candidate; old283 b2a1f4092 is not. Static diff --check
-clean. No Node, test, syntax, build, mutant or gate run. Named CLEAR/T7 still pending;288 lands last.

-  Git/filesystem library code because it is in the sandbox import closure.
-  Runtime injects the host lookup adapter; existing human file/status/sync stay.
-- Pre-flight: resolved has no project list and a library is never a checkout.
-  Bundle needs an explicit library flag from launcher business configuration.
-- M3 reading: exact creative base is five lookups plus send_message; retain
-  explicitly granted broker web_search/web_fetch for research/companion under
-  landed C2-08 and sage-2804. No generic spec, task, evidence or decision tools. Residual (mos-1308): those
-  reads lack broker action checks; their typed-tool absence is the only fence
-  for creative roles. M1/M2 deny bash; broker-side refusal is outside this row.
-  Mos confirmed this interpretation in mos-1308; design wording fix belongs to Gosalyn. Other definitions retain their current tools.
-- Multi-library businesses use an optional project ID; omit it only with one
-  configured library. Universe is required for all five tools, including get.
-- Missing library uses the brief's `library-not-configured`; argument errors
-  reuse `invalid-request` and C2-05a query codes. No new action or authority.

-## Manifest (draft code, unrun)
-
-- bus/src/broker.mjs: five lookup verbs, strict args, holder/business rechecks.
-- bus/src/runtime.mjs: host lookup adapter, stale-before-read sync, served pin.
-- harness/src/tools.mjs: five schemas; creative exact-set filtering.
-- harness/src/bundle.mjs: library flag forwarded to typedTools.
-- cli/src/launcher.mjs: one flag derived from trusted business projects.
-- bus/tests/library-lookups.test.mjs: real query/broker/socket/runtime cases.
-- harness/tests/library-tools.test.mjs: schemas, role snapshots, bundle parity.
-- cli/tests/thread-launch.test.mjs: flag reaches a real launched bundle with no library checkout.
-- agents/della/work/queue-224/BUILD.md: manifest, rulings and deferred verification ledger.
-
-## Verification ledger
-
-No test or syntax-check run yet. Acceptance requires full bus/cli/harness suites
-and every scripts/test-*.sh on Sage's gate; focused files and affected CLI/
-seat import-closure tests precede that only in an authorized CLEAR.
-
-## Coordination
-
-Huey272 reports no runtime/bundle/launcher overlap. Rocko219 changes launcher
-THREAD_DEFINITIONS checks only, separate from our buildBundle flag argument.
-The launcher argument is required: bundle cannot derive library presence from
-checkout IDs (a library has no agent clone). No role, authority or config schema
-changes; library project entries are already validated and protected by M9.
-
-## Mount and pin impact (inspection only)
-
-No new imports in broker.mjs or tools.mjs; no RUNNER_FILES or sandbox mount
-addition. runtime.mjs is host-only and already imports library index.mjs.
-Bundle forwards only a boolean, never a root/mapping/slot/credential. The
-existing import-closure tests are bus/tests/project-runtime.test.mjs and
-seat/tests/sandbox.test.mjs. Grep found no literal sha256 pin for runtime.mjs
-or bundle.mjs; bundle tests derive current source digests through SOURCES.
-Library sources remain in the existing whole-directory release copy.
-
-## Runs to schedule only after CLEAR
-
-Set TMPDIR=/mnt/storage/scratch/tmp. Focused new bus/harness files first,
-then existing library.test.mjs, library-sync.test.mjs, project-runtime.test.mjs,
-harness creative/tools/spec-tools/bundle files and affected CLI launch tests.
-Follow with the required whole bus/cli/harness suites and Sage's full shell gate.
-No timing claim yet: use the repository/Sage per-file limits and record every
-command, outcome, elapsed time and timeout before acceptance. No focused skip
-or pattern run substitutes for whole-file gate evidence.
-
-## Read-through findings and residuals
-
-- Library get requires universe although the older design table omitted it;
-  section 3 isolation rule and C2-05a's accepted API are binding.
-- Query type enum matches mapping.TYPES (five values); manuscript is a distinct
-  lookup and not a find type. Unknown host-path/commit/business/accept fields
-  are refused; explicit project is restricted to this business's library list.
-- Async reads recheck the live holder and current project revision. A stale
-  read attempts sync, then takes the new served snapshot; a returned fetch
-  failure/divergence keeps serving the old pin. Busy sync uses the current pin.
-  Unreadable state, no served commit or unsafe configuration refuse. Query
-  and sync never hold a SQLite transaction over await.
-- Processing halt refuses new agent lookup work and rechecks before returning
-  async results. Existing human library file/status/sync behavior is unchanged.
-- Timer sync and reads still use C2-03a's 60-second contract. No timer tuning or
-  resource-limit schema is introduced by this row. Q222 creative reply settings
-  are in C2-06; no reply guard or writing capability is implemented here.
-- The generic tool socket's existing 60-second client timeout can precede the
-  server's 120-second Git timeout. This row does not change the generic timeout;
-  a timed-out lookup is read-only and retryable, never a write/outcome claim.
-- All tests are authored but unrun. No RED, GREEN, syntax, runtime performance,
-  sandbox, broker/harness suite, shell gate, claim or push evidence exists yet.
-
-## Candidate review checklist (read-through only)
-
-- [x] Five verbs mapped to real C2-05a methods, all require universe.
-- [x] Default sole library or explicit owned project; no caller repo/commit.
-- [x] Human-only file/status/sync gates kept; lookup holder rechecked.
-- [x] Async socket dispatch includes lookup verbs through LIBRARY_VERBS.
-- [x] Stale/unknown fetch syncs first; results use current immutable served pin.
-- [x] Six/eight creative names per mos-1308; other roles retain their tools.
-- [x] Launcher -> bundle -> typedTools passes presence without a library clone.
-- [x] No imports added to sandbox source closure; no mount change.
-- [ ] Execute new tests, RED characterization, full files/suites after CLEAR.
-- [ ] Rebase after rows 253/216 land, under a new branch name.
-- [ ] Claim/push only in Sage-authorized gap; Dewey review and Sage gate.

-## Dewey dewey-0852 and Sage sage-2819 — focused corrections
-
-B1: inline freshness uses max(lastFetch, lastError.at), not lastFetch alone.
-An error within 60 seconds counts as a recent attempt, so later lookups serve
-the old served pin without another fetch. Keep inline sync: the brief requires
-it and businesses without timed libraries have no sync timer. The extended
-failed-fetch test makes reads at +1, +59,999 and +60,000 ms (one attempt total),
-then +60,001 ms (second attempt). All reads must return the old commit.
-
-Required mutant M-B1: remove lastError.at from recentAttempt. The repeated
-reads must fail the attempted-count assertion. This mutant has NOT been run.
-
-Residual (Sage will defer): the first inline fetch in each outage window can
-still exceed the tool timeout (60 seconds, or the runner broker client’s
-30 seconds). Bounding that fetch is out of scope for 224. Subsequent reads
-are paced by persisted lastError.at. No claim of first-read outage latency.
-
-N1: whole bus, cli and harness suites are required, plus the shell gate.
-If the new thread-launch integration test skips due to sandboxProblem(),
-name the skip; a skip is not launcher integration proof.
-N2: cli/tests/thread-launch.test.mjs now depends on library/tests/helpers.mjs
-mappingEntry() and library/tests/fixtures/mapping.json. Changes to that fixture
-must rerun the CLI launch file.
-N3: harness/tests/library-tools.test.mjs compares the type enum to mapping.mjs
-TYPES, so adding a mapped type cannot silently leave the typed tool behind.
-
-These edits are local code/docs only. No Node, RED/GREEN run, mutant, claim,
-HTTPS Git or push. New local pin goes to Dewey/Mos/Sage for focused review.

-
-## mos-1330 old-test migration (separate commit)
-
-All paths below are packages/library/tests/query.test.mjs. Baseline file at
-fc05bcbc3 matches216's file. Source assertions retained; negative calls receive
-explicit scope too, so universe isolation cannot pass on default-scope denial.
-
-Call/assertion 348 -> 348:
-
-```js
-// OLD
-  const rin = await get(s, { universe: 'idea', path: 'Drafts/New World/Characters/Rin.md' });
-// NEW
-  const rin = await get(s, { universe: 'idea', path: 'Drafts/New World/Characters/Rin.md', scope: 'playground' });
-```
-
-Call/assertion 350 -> 350:
-
-```js
-// OLD
-  assert.equal(await get(s, { universe: 'harbor', path: 'Drafts/New World/Characters/Rin.md' }), null);
-// NEW
-  assert.equal(await get(s, { universe: 'harbor', path: 'Drafts/New World/Characters/Rin.md', scope: 'playground' }), null);
-```
-
-Call/assertion 366 -> 366:
-
-```js
-// OLD
-  assert.equal(await get(src(ref, mapping(WITH_BLEND)), { universe: 'blend', path }), null);
-// NEW
-  assert.equal(await get(src(ref, mapping(WITH_BLEND)), { universe: 'blend', path, scope: 'playground' }), null);
-```
-
-Call/assertion 367 -> 367:
-
-```js
-// OLD
-  const own = await get(src(ref), { universe: 'harbor', path });
-// NEW
-  const own = await get(src(ref), { universe: 'harbor', path, scope: 'playground' });
-```
-
-Assertion 349 retained, OLD == NEW:
-
-```js
-  assert.equal(rin.scope, 'playground');
-```
-
-Assertion 368 retained, OLD == NEW:
-
-```js
-  assert.equal(own.scope, 'playground');
-```
-
-The null assertions at350 and366 are the complete OLD/NEW expressions above:
-expectation remains null. Added one separate no-scope playground-get -> null
-behavior test. It is unrun and expected to expose old get behavior until the
-new scope implementation lands. This migration is authorized by mos1330 under
-mos1272; no check removed or weakened. Dewey checks this list in manifest review.
-
-## 283 surface and blob choice
-
-Inspected actual46bad7ea3: optional editor.user is present. reader's parsed
-file records and index entries still discard tree oid. In owned query.mjs use
-the existing bounded listTree(repo, servedCommit) to obtain exact path oid,
-not HEAD and not a user-supplied revision expression. No reader/index edit.
-Tradeoff: one additional bounded tree listing per get; latency unmeasured.
-Recheck after rebasing to283's actual landing.
-
-## Intended owned paths
-
-query.mjs; broker.mjs lookup branch; tools.mjs lookup schemas/descriptions;
-library query.test.mjs/query-fixture.mjs; bus library-lookups.test.mjs;
-harness library-tools.test.mjs; this BUILD.md. Other files are prerequisites.
-
-## Gate
-
-Dewey manifest approval, whole library/bus/harness suites and every
-scripts/test-*.sh on Sage gate. Before review grep all package tests for enum
-pins and canon/playground pairs. Keep shared logs out; send receipts to Sage.
-No test or mutant evidence claimed. Manifest/digest follows complete code.
-
-## Implementation head (UNTESTED, sage-3658)
-
-- query scope accepts supporting for find/search/get. get defaults canon,
-  mismatch null. Manuscript passes a separate two-value scope allowlist.
-- get returns blob from listTree(source.repo,index.commit) after scope/universe
-  filtering. The same index.commit supplies the text; source HEAD is irrelevant.
-- Full outgoing and incoming link lists are stably sorted by supporting,
-  playground,canon before combining/paging. All visible cross-scope links stay;
-  universe/hybrid visibility still applies. Scope metadata isn't added to links.
-- Broker only adds optional scope to library.get's strict fields. No new verbs.
-- Typed scope expands find/search/get only; manuscript retains its own two-value
-  enum. Names/M3 counts remain the row224 six/eight, no write tools added.
-- New tests: book/universe/draft supporting find/search/get; defaults/mismatch;
-  absent supporting prefix; source HEAD advances but each scope's blob equals
-  served:path; 300 outgoing plus300 incoming links ordered across bounded pages,
-  retaining cross-scope links and dropping other-universe links; hybrid source
-  stays canon-only; no all/array scope; manuscript rejects supporting; broker
-  scope/blob forwarding; typed enums and unchanged names. All unrun.
-
-## Additional old assertion pin (brief Gate)
-
-harness/tests/library-tools.test.mjs:49 at23816cf28 (line49, unchanged in this head):
-OLD find scope enum ['canon','playground']; NEW ['canon','playground','supporting'].
-This is the exact scope-enum pin the brief directs updating. Existing six/eight
-name snapshots and TYPES equality assertion are unchanged. The new manuscript
-pin intentionally remains ['canon','playground']. No other two-scope test pin
-was found by rg over packages/*/tests at this build's prerequisite merge.
-
-## Proposed mutation evidence (reviewer confirms final set)
-
-All unrun. Require assertion failures with whole-file runs and pristine restore:
-M1 remove supporting from query SCOPES -> supporting lookup cases.
-M2 drop get's requested-scope comparison -> default/mismatch null cases.
-M3 use source HEAD for blob lookup -> served-tree/advanced-HEAD equality case.
-M4 remove link rank sort -> multi-page outgoing/incoming expected order.
-M5 restrict links to requested scope -> cross-scope link counts/order case.
-M6 drop sees() from visible/link filtering -> second-universe/hybrid cases.
-M7 allow supporting in manuscript validator -> manuscript refusal case.
-M8 omit get scope from broker fields -> real broker supporting get case.
-M9 widen typed manuscript enum -> typed-scope separation case.
-
-## Inspection and pending gate
-
-No production imports change in broker/tools, so no new sandbox closure file
-or mount. query.mjs is host library code and adds existing reader.listTree;
-no new package/export/copy-path file. rg found the one old find scope pin plus
-the intentional new manuscript two-scope pin. Whole library/bus/harness and
-shell gates remain required. CLI integration/merge context is prerequisite224/
-219, not this row's source delta; any changed gate expectation goes to Sage.
-Node checks, tests, mutants and elapsed-time evidence remain absent pending
-CLEAR. The first test-migration commit and this implementation are distinct.
-
-Sage sweep receipt: Della row284 builds on28346bad7ea3 plus intact224 merge;
-mos1330 old-test migration separate, supporting scope/blob implementation and
-fixtures authored, completely UNTESTED. No shared-log/queue write or live action.
-
-## Current assertion anchors after implementation imports
-
-The separate migration commit0ed4fbab9 retains its complete OLD/NEW text
-above. Adding only the fs/path imports in the implementation shifts anchors:
-
-query.test.mjs:130: `const blendCh2 = await get(src(ref, mapping(WITH_BLEND)), { universe: 'blend', path: 'Book One/Chapters/Chapter 02.md' });`
-query.test.mjs:350: `const rin = await get(s, { universe: 'idea', path: 'Drafts/New World/Characters/Rin.md', scope: 'playground' });`
-query.test.mjs:351: `assert.equal(rin.scope, 'playground');`
-query.test.mjs:352: `assert.equal(await get(s, { universe: 'harbor', path: 'Drafts/New World/Characters/Rin.md', scope: 'playground' }), null);`
-query.test.mjs:368: `assert.equal(await get(src(ref, mapping(WITH_BLEND)), { universe: 'blend', path, scope: 'playground' }), null);`
-query.test.mjs:369: `const own = await get(src(ref), { universe: 'harbor', path, scope: 'playground' });`
-query.test.mjs:370: `assert.equal(own.scope, 'playground');`
-
-No result/null assertion changed; scope arguments carry the explicit opt-in.
-
-## Dewey dewey-0941 static review — round2
-
-Static scope fc05bcbc3..47db04eba CLEAN; not a final verdict or test evidence.
-M1-M9 accepted as the final set. Optional M10 not added to this gate.
-N2 taken: keep the existing canon-path supporting-scope mismatch assertion,
-and ADD get(Book One/Support/Notes/Helper.md,scope:supporting) -> null under
-the default mapping with no supporting prefix. The supporting-positive test
-already returns this same path under withSupporting, so the added probe
-pins the missing-prefix case directly. No assertion removed or weakened;
-mos1330's separate migration commit and its retained assertions unchanged.
-
-N1 proposed DEFERRED/follow-up for Sage: retain each tree oid in reader/index
-entries so get can return blob without cat-file/whole ls-tree -r -l per page.
-Current get's result is pinned correctly, but per-page cost grows with the
-library. No performance measurement yet. This optimization needs reader/index
-ownership and separate acceptance/performance evidence; do not silently expand
-284's manifest or change its served-snapshot contract for it.
-
-No Node, tests, mutants or syntax checks run in this round; hold still applies.

-## 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).
-
-## r2 rebase (sage-3579)
-
-Sage ruled that 286 now goes before 258, because 222 is its only after row. Branch ludwig/row286-r2
-rebases b9506b352 (base 94c33a43c) onto origin/refactor 45dca69f6. The rebase had no conflicts.
-
-- Range-diff 94c33a43c..b9506b352 against 45dca69f6..r2: all 11 commits are `=`, so no patch
-  changed.
-- Rows 254 (331597709) and 268 (c27207f6e) were already in the old base 94c33a43c. Between the two
-  bases nothing changed under packages/library.
-- Paths the two test files import or read, diffed 94c33a43c..45dca69f6: bus broker.mjs, runtime.mjs
-  and store.mjs changed. None of the others changed: library/*, bus credentials, gitea-grant,
-  mapping, mirror, reader, survey, sync, the fake-gitea-api, helpers and host-fixtures modules,
-  business helpers (rolesCopy, systemFor), project git, seat checkout and fake-gitea, and roles/.
-  - broker.mjs: the constructor gains `accessStamp` and `compactions`, both defaulting to null, and
-    my tests pass neither. No base hunk falls in the fire job, the revoke job or the instance.fire
-    verb. Old :4308/:4335 are now :4852/:4879, with the same text. The new console-cap check refuses
-    a non-console session only on CONSOLE_VERBS, and the library verbs are not among them. The
-    request path's access re-read applies only to `s.user` sessions, and my tests open none.
-  - runtime.mjs: consoleOwners (default []), the access timer, compactions and the session-clear
-    hooks. The Credentials and giteaStart wiring that T9 uses is unchanged.
-  - store.mjs: schema 3l to 3n (row 206 thread_shares, row 271 session_ops and message_cancels).
-    Each test opens a fresh Store, and none pins a schema version or step count.
-- Hash pins: no test or script line pairs a 64-hex value with a path I change. The positive
-  control finds 64-hex pins in, for example, account-migration.test.mjs.
-- Row 285 has not landed. roles/chief-of-staff.json at 45dca69f6 still names no gitea credential,
-  so T9 keeps its scratch roles copy (sage-2947).
-- sage-3589 freezes stack-release.sh, webui-service.sh, bus-service.sh, stack-copy.sh and common.sh.
-  This row changes none of them.
-- Still to run, on CLEAR: library and bus whole, every scripts/test-*.sh, M1 and M2, and the token
-  search, all on r2.

+## Status
+
+| Item | State |
+|---|---|
+| M7 reader side (`conversation-not-listed`) | Built. Tests written, not run. |
+| M7 production wiring (the caller that passes `isCreative`) | Not built. Outside the file list, and it needs a ruling (question 1). |
+| M8 `discord check` and `discord run` refusals | Not built. `packages/discord/src/cli.mjs` is untouched. Blocked on question 1 and question 2. |
+
+Phase A is therefore partial. The row cannot pass its acceptance until Sage rules on the questions below.
+
+## Files
+
+- `packages/conversation/src/reader.mjs`: exports `NOT_LISTED`; `createReader` takes `isCreative` (default `() => false`); `catalogue()`, `open()` and `next()` hide a root for which it returns truthy.
+- `packages/conversation/tests/reader.test.mjs`: three new tests, inserted before the "unknown conversations" test.
+- `agents/researcher/work/queue-220/BUILD.md`: this file.
+
+Nothing else is changed. `node_modules` in the worktree is a symlink to the canonical checkout and is ignored by git.
+
+## Brief and design items mapped to tests
+
+| Item | Test |
+|---|---|
+| M7: a creative session file under the root isn't listed | "M7: a creative seat's session is not listed and won't open by id; an assistant seat still lists" |
+| M7: and won't open by id (`conversation-not-listed`) | same test; second check of the open refusal in "M7: a creative session already open refuses its next page once the root is hidden" |
+| M7: an assistant session still lists | same test (the `sage` seat is listed and opens with its text) |
+| M7: an already-issued cursor stops once the root is hidden (my addition; the design's "won't open" implies it) | "M7: a creative session already open refuses its next page once the root is hidden" |
+| M7: refused rows and the unsupported placeholder of a creative root are hidden too (my addition; the design hides "creative sessions", and a refused row or placeholder names one) | "M7: a creative root's refused files and its unsupported placeholder are hidden as well" |
+| Default behavior without `isCreative` is unchanged | the existing reader suite; the default predicate returns false |
+| M8: `discord check` / `discord run` refuse `discord-engine-not-allowed` on a library business, and a `mosaic-bus` binding with `tools` | none (not built, question 1) |
+| M8: a pi binding on a business without a library still checks clean | none (not built, question 1) |
+
+Every test's fixture text is `CREATIVE-MARKER` or a made-up assistant line. The M7 tests assert the marker is absent from the catalogue and refusal output.
+
+## Choices made in phase A
+
+- `isCreative(root)` is the reader's only input. The reader reads no business file. A truthy answer hides, so a doubtful answer fails closed. The predicate must depend on `root.seat` and `root.project` only, because a cursor is checked against the root object from an earlier listing.
+- Hidden check placed after the cursor's actor/purpose/conversation/branch checks in `next()`, and before the source is read.
+- `open()` checks hidden after the id resolves, so a creative id gets `conversation-not-listed`, and an unknown id still gets `unknown-conversation`.
+- `conversation-not-listed` is `reconcile: false`. The design names no reconcile flag. `unknown-conversation` uses true. Question 3.
+- The default predicate is `() => false`. Until a caller passes one, M7 does nothing. This is the open risk, and question 1 covers it.
+
+## Grep over `packages/*/tests` and `scripts/test-*.sh` (static, phase A)
+
+Changed path `packages/conversation/src/reader.mjs`:
+- `packages/conversation/tests/reader.test.mjs:14` imports `rootsFromSpecs, createReader, conversationId, cwdInProject, UNSUPPORTED_HARNESS`. It is the file under change.
+- `packages/control-board/tests/serve.test.mjs:26` imports `UNSUPPORTED_HARNESS`. That export is unchanged.
+- `packages/library/tests/sync.test.mjs:15` imports `packages/library/src/reader.mjs`, a different file. Not a hit.
+- `scripts/test-*.sh`: no reference to the conversation reader.
+- 64-hex pins naming this path: none. `packages/bus/tests/grant-migration.test.mjs:24` has a 64-hex value, but it is a DDL digest, not a pin on this path. That file matched only the word "reader" in a test title.
+
+Changed path `packages/conversation/tests/reader.test.mjs`:
+- No other test or script names this file. It runs through `packages/conversation`'s `node --test tests/`.
+- No 64-hex value in the file.
+
+Changed path `agents/researcher/work/queue-220/BUILD.md`: no pin.
+
+`node --check` passed on both changed `.mjs` files.
+
+## Phase B plan (not run)
+
+The reader test uses `os.tmpdir()`. Set `TMPDIR` to a scratch dir first, per the rule against `/tmp`.
+
+```
+export TMPDIR="$(mktemp -d /mnt/storage/scratch/tmp/r220XXXXXX)"
+cd packages/conversation && node --test tests/reader.test.mjs
+cd packages/conversation && node --test tests/
+cd packages/discord && node --test tests/
+cd packages/control-board && node --test tests/serve.test.mjs
+```
+
+The first command is the touched file whole. The second and third are the conversation and discord suites whole, as the brief asks. The control-board serve test is not in the brief. It consumes `reader.mjs`, so I recommend it. Sage can drop it.
+
+## Questions for Sage
+
+1. **Business link (blocks M8 and the M7 wiring).** Neither rule can be built from this row's file list, because the inputs don't exist in the code:
+   - A reader root carries `seat` (the spec's `agent`) and `project` (the repo directory name). It has no business id. Roots come from control-board scan specs (`packages/control-board/src/scan.mjs`, `discoverRepoAgents`) and seat registrations. Neither carries a definition.
+   - A Discord binding has `seat` and no business key (`packages/discord/src/binding.mjs`, `TOP_KEYS`).
+   - Creative status lives only in the business file: `roles.<instance>.definition` in `CREATIVE_DEFINITIONS` (`packages/business/src/vocabulary.mjs:176`). A library project is `projects.<id>.kind === "library"` (`packages/business/src/business.mjs:243`).
+   - Creative thread sessions are stored at `<dataRoot>/threads/<business>/<thread>/session` (`packages/seat/src/session.mjs:59-64`), outside the `.pi/state` roots the board scans. M7 may therefore reach only creative seats that have a `.pi/state` session root. Please confirm.
+   - The design does not define the mapping from a seat to a business.
+
+   Recommendation: add a required `business` key to the binding, validated against `businesses/<id>.json`. The board builds `isCreative` from `loadBusiness(id)`: a root is creative when its seat is a `roles` key whose definition is in `CREATIVE_DEFINITIONS`, and the business has a library project. This needs file scope for `packages/discord/src/binding.mjs` and `cli.mjs` (M8), and `packages/control-board/src/serve.mjs` (M7 wiring). None of those is on this row's list. I need that scope amendment and the mapping ruling before I build M8 or the wiring.
+
+2. **M8 refusal code for a `mosaic-bus` binding with `tools`.** The design names `discord-engine-not-allowed` for the engine case and no code for the tools case. A new code goes to you first. My proposal is to reuse `discord-engine-not-allowed` with a message that names the tools key.
+
+3. **`reconcile` on `conversation-not-listed`.** I chose `false`. Confirm or change.
+
+4. **HTTP status for `conversation-not-listed`.** `REFUSAL_STATUS` in `packages/control-board/src/serve.mjs` has no entry, so the route returns 422. My proposal is 404, next to `unknown-conversation`. This needs that file on the scope list too.
+
+Phase A stops here. On your "slot clear" I will run the phase B commands above. I will not build M8 or the wiring until question 1 is answered.

+# Row 220 r2: phase A round 2 (M7, M8, business helper, REFUSAL_STATUS)
+
+Phase A only. No node, npm, `node --check` or test run has happened in this round, and nothing is
+committed. Phase B (the suites) waits for the coordinator's "slot clear".
+
+- Owner: researcher seat (Haiku 5.5 subagent), dispatched by Sage under lead decision 129.
+- Reviewer: Filbert.
+- Branch: `researcher/row220-r2`, from `origin/refactor` at da9555ca2. The r1 cherry-pick 3fa833715 is
+  staged with `-n`.
+- Rulings: `agents/sage/work/queue-220/RULINGS.md` on origin/refactor (da9555ca2). Import-by-path is
+  followed: no export line in `packages/business/src/index.mjs`, and `packages/discord/src/binding.mjs`
+  is untouched.
+
+## Coordinator rulings, applied
+
+Round 1 answers (earlier packet): applied as before. Absent `businesses/` gives empty sets only on
+ENOENT; other failures throw. stack-copy test joins phase B. Webui fixtures pass `businessDir` (renamed `configDirectory` in round 2b below). Discord
+refusals exit 2.
+
+Round 2 rulings (coordinator message, this round):
+
+1. **Dangling symlink at `businesses/` refuses.** `loadSeatSets` calls `lstatSync(join(dir, "businesses"))`
+   first. Only an lstat ENOENT (nothing at the path) returns empty sets. If something is there and
+   `readdirSync` fails for any reason, including ENOENT through a dangling link, it throws `BusinessError`.
+   Test added: "a businesses symlink to a missing target throws; no empty set". The absent-directory test is kept.
+2. **Sets are read once per public reader call.** `createReader` takes `creativeCheck`, a factory. Each
+   `catalogue()`, `open()` and `next()` calls it once, then applies the returned predicate to every root.
+   A load failure refuses `conversation-business-unreadable` for the whole call. `serve.mjs` exports
+   `creativeCheck(dir = configDir())`, the factory, and `createServer` passes `creativeCheck(businessDir)`.
+   Test added: "one catalogue calls the creative check once, however many roots it lists". It counts factory
+   calls: 1 after `catalogue()`, 2 after one `open()`.
+3. **Phase B adds three test files:** `packages/webui/tests/tester-browser.test.mjs`,
+   `tester-cli.test.mjs` and `proof-cli.test.mjs`, run whole (they reach `fixture.mjs` through
+   `tester-fixture.mjs`). Phase B is 36 files: 33 plus these 3.
+4. **Scope additions approved** (coordinator round 2 ruling 4): `packages/control-board/tests/discord.test.mjs`
+   line 123 and the five webui test files (`fixture.mjs`, `history-fixture.mjs`, `relaunch.test.mjs`,
+   `return-flow.test.mjs`, `discord.test.mjs`). They stop tests reading the real config directory.
+5. **TMPDIR** for phase B is set by the coordinator under `/mnt/storage/scratch/tmp`. No code change.
+
+## Discord exit code
+
+Refusals from the library-seat check exit 2, the code the Discord CLI already uses for configuration and
+binding refusals.
+
+- `packages/discord/src/errors.mjs` line 2: `// exitCode follows docs/TOOLS.md: 1 operation failed, 2 invalid data or configuration, 3 refused by a brake (STOP or a held binding; a supervisor must not retry), 4 usage.`
+- `packages/discord/src/errors.mjs` line 5: `constructor(message, exitCode = 2, details = undefined)`.
+- Config refusal precedent: `packages/discord/src/binding.mjs` line 67, `throw new DiscordError(\`config.dataRoot must be an absolute path: ${path}\`);`. No explicit code, so exit 2.
+- `checkLibraryEngine` in `packages/discord/src/cli.mjs` lines 115 to 122. Each refusal passes `, 2)`:
+  `discord-business-unreadable` (115), `discord-engine-not-allowed` for a non-mosaic-bus engine (119),
+  and `discord-engine-not-allowed` for a mosaic-bus binding that declares `tools` (122).
+- `grep -n ", 3)" packages/discord/src/cli.mjs` finds nothing. `grep -rn "status, 3" packages/discord/tests`
+  finds only existing brake tests in recover.test.mjs and binding.test.mjs. Not changed.
+  `library-seat.test.mjs` asserts 2 on all three refusals.

+
+## Choices (for Filbert to check)
+
+1. **Absent versus unreadable `businesses/`.** Only nothing at the path reads as empty (lstat ENOENT). A
+   dangling symlink, a file, or an unreadable directory throws. Coordinator ruling 1.
+2. **Sets are read once per public call.** `creativeCheck()` runs once in each of `catalogue()`, `open()` and
+   `next()`. The returned predicate answers every root in that call. A catalogue with zero roots still
+   loads the sets once, so an unreadable business file refuses even an empty list. Coordinator ruling 2.
+3. **Behavior change, kept on coordinator ruling (round 2 follow-up): an unknown id or cursor loads the sets
+   first.** In `open()`, the check runs after `checkCaller` and before `resolveConversation`. In `next()`, it
+   runs at the start of the try. So with an unreadable business file, a known id and an unknown id both give
+   503 `conversation-business-unreadable`, where round 1 gave 404 `unknown-conversation` for the unknown id.
+   Checking the id first would give 503 for a hidden creative id and 404 for an unknown one, which reveals
+   whether the hidden id exists. Loading first answers every id the same way (fail closed). This reverses
+   round 1 choice 3. Test: `creative-hidden.test.mjs` "with an unreadable business file, a known and an unknown id both refuse with 503".
+4. **Discord refusals use the `code: message` form and exit 2.** Exit 3 is for brake refusals (STOP or a held
+   binding). A seat's engine or library membership is not a brake. The business CLI is not used as precedent.
+5. **The thread-store wall exists in part already.** `rootsFromSpecs` (`reader.mjs` line 44) drops any
+   sessions directory that is not `<project>/.pi/state/<seat>/sessions`. The M7 check is the second wall, for
+   roots built another way. The test checks both.
+
+## Static checks (read-only; no node)
+
+- **COPY_PATHS** (`scripts/stack-copy.sh` 29 to 41): `packages/business/src`, `packages/conversation/src`,
+  `packages/discord/src` and `packages/library/src` are present. `packages/control-board/src` is not. COPY_PATHS
+  is not changed.
+- **Stale names.** `grep -rn -E "isCreative|creativeRootPredicate" packages scripts` finds nothing after this round's edits.
+- **Board starts without `businessDir`.** Webui: all five direct starts pass it. Control board:
+  - `serve.test.mjs` has seven single-line starts without it (lines 402, 445, 464, 483, 509, 528, 907) and four
+    multi-line starts without it (114, 149, 229, 258). None of those tests reaches a conversation route.
+    Every conversation route call in the file (lines 1027 to 1171) follows a start that passes `businessDir`
+    (1006, 1075, 1124). Checked by line order.
+  - `creative-hidden.test.mjs` builds `creativeCheck(f.dir)` on its own scratch directory. No default is used.
+  - `discord.test.mjs` passes `businessDir` (line 123).
+- **Consumers of the two fixtures** (exact import strings, `from './fixture.mjs'`, `from './history-fixture.mjs'`):
+  - Direct `fixture.mjs` importers, 31 test files: board-held, browser-edge, browser, bus-browser, bus,
+    chat-browser, chat, discord, docs-browser, editor-browser, editor, instances-browser, limits-browser,
+    limits-route, messages, preview, proof, relaunch, return-flow, routes-browser, send-browser, send, serve,
+    settings-form, shell, sso-browser, sso, tester-listener, usage-browser, usage, views.
+  - `history-fixture.mjs` importers, 2 test files: conversation, history-return-flow.
+  - Total fixture consumers: 33. Plus `tester-browser`, `tester-cli` and `proof-cli` (through
+    `tester-fixture.mjs`, ruling 3): 36 files in phase B.
+
+## Phase B commands (after "slot clear" only)
+
+TMPDIR is set by the coordinator under `/mnt/storage/scratch/tmp`. The commands below assume it. The new
+tests call `tmpdir()`, so an unset TMPDIR would put them under `/tmp`, which bwrap hides.
+
+```sh
+cd /mnt/storage/src/mosaic-stack/.claude/worktrees/agent-a1b36cb7769b3d00e/packages/conversation && node --test tests/

+```
+
+The webui line is 36 files, run whole. `history-fixture.mjs` and `tester-fixture.mjs` run through their
+consumers. No test has been run. The expectations above come from reading the code.
+
+## Open items
+
+a. Phase B checks the dangling-symlink test on this platform (lstat then readdir ENOENT must throw).
+b. Phase B checks the spy count (1 after catalogue, 2 after one open). A failure here means a public call
+   reads the factory more than once.
+c. Choice 3 is settled by the coordinator: keep 503 for unknown ids too. Phase B checks the new known-and-unknown test.
+d. The browser-based webui tests need a browser in this environment. A failure there would be environmental.
+   Phase B will show which.
+e. Nothing here has been executed. Phase B checks every expectation, including the unreadable-file test
+   (EACCES must throw), the root skip (uid 0 skips), and the webui consumers.
+
+## Resolved
+
+- Dangling symlink at `businesses/` (round 1 open item a, and round 1 question 1): refuses, ruling 1.
+- Tester and proof CLI tests (round 1 question 2): join phase B, ruling 3.
+- Per-root reads (round 1 open item b): replaced by one read per public call, ruling 2.
+
+## Rebase onto aca16404c, run limits, index export (2026-10-22, sage-2708)
+
+Added after the text above; nothing above is edited. "Nothing is committed" above was true when written.
+
+- Commit `6f656abac` on `researcher/row220-r2`, one commit, rebased from da9555ca2 onto origin/refactor
+  `aca16404c`. Row 253 has not landed; this rebases again onto 253's tip before any gate.
+- Drift check, da9555ca2..aca16404c against my 18 paths: one overlap, `packages/discord/src/cli.mjs`
+  (the processing-control imports, rows 264 and neighbours). The conflict was the import block only. I
+  kept both sides: the two landed `processing-control` imports and my `loadSeatSets` import. No landed hunk
+  is reverted. `checkLibraryEngine` and its call in `prepare()` merged without a marker.
+- Board starts: no test added since da9555ca2 starts the control board or reads a conversation route
+  without `businessDir`. `packages/webui/tests/shell.test.mjs` fakes the board and does not start it.
+- Two edits since the r2 text: (1) a missing space in `reader.mjs` `next()` (`held =typeof`) fixed;
+  (2) `packages/business/src/index.mjs` gets `export { loadSeatSets } from "./library-seats.mjs";`. The text
+  above says "no export line". RULINGS.md Q1 says the helper is "exported from the package index" and the
+  scope amendment lists "its export line", so the file wins and the export is added. The two callers still
+  import by path, so nothing needs the export today. Filbert: drop the line if you read the ruling otherwise.
+  The export adds no test; `node --check` has not been run on it (no node before the CLEAR).
+
+### Run limits (fixed before any run)
+
+Every node file runs as its own `setsid -w timeout -k 10 LIMIT node --test FILE`; nothing runs unbounded.
+
+- Node test files: LIMIT 900 s. I found no recorded per-file time for the conversation, discord, business,
+  control-board or webui files. 900 s is above the longest recorded whole-package run I know of (cli, 591 s,
+  row 281 BUILD.md "Runs" step 3), so it holds the 3x rule for any single file. The first run records each
+  file's time; if a file passes 300 s, the limit is re-derived from it before the next run.
+- Shell scripts: `timeout -k 10 LIMIT bash scripts/test-X.sh`, LIMIT = 3x the longest recorded run plus
+  120 s, taken from Megavolt's row 281 table (`agents/megavolt/work/queue-281/BUILD.md`, from Gander's
+  `agents/gander/work/queue-278/SHELL-LIMITS.json`). A script with no limit does not run.
+
+| Script | LIMIT | Script | LIMIT |
+|---|---|---|---|
+| test-auth | 126 s | test-land-work | 158 s |
+| test-conductor | 145 s | test-queue | 191 s |
+| test-config | 130 s | test-release | 157 s |
+| test-discord | 147 s | test-task | 231 s |
+| test-extension-package | 130 s | test-foundation | 240 s |
+
+Any timeout goes to Sage, then Mos, unplaced (mos-1275).
+
+## Round 2b: Filbert's early look and sage-2719 (2026-10-22T14:46Z)
+
+Added after the text above; nothing above is edited. Where earlier text says `businessDir`, the parameter is
+now `configDirectory` (below). Second commit on `researcher/row220-r2`, on top of ea6dc9eff. Not pushed, not
+run; `node --check` has not been run on any of these files (no node before the CLEAR).
+
+Rulings applied (sage-2719): Q1 keep the index export. C1, C2 and the fixture scope are changes.
+
+### Fixture scope: the parameter is a config directory
+
+`createServer` took `businessDir`, but `creativeCheck(dir)` reads `<dir>/businesses`, so every fixture that
+passed `join(root, 'businesses')` made the reader look in `<root>/businesses/businesses`. That read nothing
+(ENOENT, empty sets): isolation from the real config held by accident. Now:
+
+- `createServer({ configDirectory = configDir() })` in `serve.mjs`. The parameter is not named `configDir`
+  because the import of that name is the default's source.
+- Every fixture passes the config directory it owns: `configDirectory: root` in the five webui files,
+  `f.root` in `control-board/tests/discord.test.mjs`, and `f.configDirectory` in `serve.test.mjs`.
+  `conversationFixture()` and `replyFixture()` both return `configDirectory: root`. The seven reply starts
+  that passed `f.businessDir` (undefined, falling back to the real `configDir()`) now pass a real value.
+- The dead `mkdirSync(join(root, 'businesses'))` lines in the five webui fixtures and in `serve.test.mjs`
+  are removed. So is the one in `discord/tests/helpers.mjs` `makeDeployment`, whose comment said "a missing
+  one refuses"; that was false (lstat ENOENT gives empty sets). The comment now says nothing there means no
+  library seat. Tests that need a `businesses/` directory create it: `writeJson` does, and the two
+  unreadable-file tests in `library-seat.test.mjs` call `mkdirSync` themselves.
+- Proof that the fixture's own business file is the one read: the new default-reader test (C2) hides `bean`
+  and shows `pm`, and nothing else in that fixture says which is which.
+
+### C1: M8 on `run`
+
+`library-seat.test.mjs` gains three `run` tests: a raw engine, a mosaic-bus binding with `tools`, and an
+unreadable business file. Each asserts exit 2 and the code in stderr, and that `s.d.journalDir` does not
+exist (`ensureJournal` comes after `prepare()` in `run`, so nothing was started). `run()` calls
+`initializeControl(dataRoot)` first, because `run` stops at `assertProcessing` before `prepare()`, as the
+STOP test in `binding.test.mjs:203` does. There is no `run` test for a clean seat: that would go on to the
+network.
+
+### C2: the default reader
+
+`creative-hidden.test.mjs`, "the board's default reader hides a creative seat's session from the listing and
+the detail route". It calls `startServer` with no `conversationReader`, `configDirectory: f.dir`, a `bean`
+session and a `pm` session on disk, and drives HTTP: the listing holds `pm` only; bean's detail is 404
+`conversation-not-listed`; pm's detail is 200; after a broken business file lands the listing is 503
+`conversation-business-unreadable`.
+
+### Mutants to throw (CLEAR only; none thrown; the kill claims are unverified)
+
+| Id | Mutation | Meant to be killed by |
+|---|---|---|
+| M7-w | delete `creativeCheck: creativeCheck(configDirectory),` in `createServer` (`serve.mjs`) | the default-reader test, first assertion (the listing shows `bean`) |
+| M7-c | `hiddenCheck()` in `reader.mjs` open() returns `() => false` | reader.test "hides the creative seat" and the `creative-hidden` 404 asserts |
+| M7-o | `creativeCheck` catch returns an empty set instead of throwing | the 503 asserts in `creative-hidden` |
+| M8-p | delete `checkLibraryEngine(...)` in `prepare()` | the three `check` refusals and the three `run` refusals; one mutant covers both verbs because they share `prepare()` |
+| M8-e | `loadSeatSets` returns empty sets on any lstat error | `library-seats` ENOENT-vs-file tests |
+
+### `refusalResponse` and `catalogue()`'s refusal (past "predicate wiring and REFUSAL_STATUS only")
+
+Why it is needed: the reader's `catalogue()` now returns a refusal when the business check throws (M7: no
+partial list), and `conversationResponse` had no way to turn a catalogue refusal into a status. `open` and
+`next` already built `{ status: REFUSAL_STATUS[code] ?? 422, body: { error, refusal: { code, reconcile } } }`
+inline; that expression moved, character for character, into `refusalResponse(out)` so the listing could
+use it too.
+
+No existing route's status or body changes:
+
+- `open` and `next` refusals: the same expression, now behind a function. `git diff aca16404c..HEAD --
+  packages/control-board/src/serve.mjs` shows the line as a move.
+- `/api/conversations` success: `{ status: 200, body: listing }` where `listing` is what the route returned
+  before. `catalogue()` returned `ok: true` on every path before this row, so the new branch is reached only
+  by the business refusal.
+- The "no parameters are accepted" 400 is untouched.
+
+Phase B runs `serve.test.mjs`, `discord.test.mjs` and the conversation route tests whole, so Filbert can
+check this statement against a green run.
+
+### Smaller changes from the early look
+
+- Spy test: one `next()` call adds a third `creativeCheck` count (`reader.test.mjs`). The catalogue assert
+  also checks `refusedRoots` is empty, in the same test and in the thread-store test in `creative-hidden`.
+- `library-seats.test.mjs` mode-000 test pins `BusinessError` and its message (`must be a regular,
+  non-symbolic-link file`, from `readJsonFile`'s open failure).
+- "passes the engine rule" now asserts exit 0 and `offline check passed`. The expectation is unverified: if
+  a mosaic-bus binding fails some other offline check, that is a first-run red to place (mos-1272).
+
+### Carried, not changed here
+
+- `conversation/src/controller.mjs:176` builds a reader with no `creativeCheck`. No `src` file imports it
+  today; a live wiring must pass the check. Raised for Sage.
+- `discord run` reads the business file once at start. `engine` and `tools` are FIXED_KEYS, so only a
+  business-file change while a connector runs goes unseen until the next start.
+- `creative-hidden` and `library-seats` use the repo `roles/` as the default `rolesDir`.
+
+### Gate additions
+
+Phase B list is unchanged: the same suites run whole, plus the files above are inside them. The drift check
+against `aca16404c..refactor`, including files these tests copy or read, repeats after the rebase onto 253.
+
+## Round 2c: refusalResponse statement corrected from the diff, controller.mjs follow-up (2026-10-22T14:55Z, sage-2729)
+
+Appended after Round 2b; nothing above is edited. This replaces Round 2b's refusalResponse statement, which I
+wrote from memory of the code. Source: `git diff aca16404c HEAD -- packages/control-board/src/serve.mjs` and
+`packages/conversation/src/reader.mjs`, read in full. No test has run.
+
+### What the diff shows in serve.mjs
+
+- `open` and `next` refusal: the object expression `{ status: REFUSAL_STATUS[out.refusal.code] ?? 422, body: {
+  error: out.refusal.message, refusal: { code, reconcile } } }` moved unchanged into `refusalResponse(out)`.
+  The two call sites reach it by `return refusalResponse(out)`. Status and body are identical for every code
+  that reached it before.
+- `REFUSAL_STATUS` gains two keys, `conversation-not-listed` (404) and `conversation-business-unreadable`
+  (503). Before, those codes did not exist, so no earlier response used them or changes. Every other key is
+  untouched.
+- `/api/conversations` with a query string: the 400 `no parameters are accepted` line is untouched.
+- `/api/conversations` success: before, `{ status: 200, body: reader.catalogue() }`; now the same object
+  when `listing.ok` (it is the same `listing`), so the 200 body is unchanged.
+- The one new response shape: `/api/conversations` can return a refusal (503 or the refusal's status) when
+  the business check throws. That is the M7 behaviour, not a change to an existing route's response.
+
+### What the diff shows in reader.mjs, past my Round 2b statement
+
+`catalogue()` is now wrapped in `try { ... } catch (err) { return refuse(err); }`. `refuse` returns a refusal
+object for a `Refusal` and rethrows anything else (`reader.mjs:352-355`). So a non-Refusal error still
+propagates as before. A `Refusal` escaping the loop body would now come back as `{ ok: false }` where it
+used to throw. The loop already catches `Refusal` from `listSessionFiles` and from `summarize`, so the only
+`Refusal` that newly reaches the wrapper is the hidden check's. I have not confirmed that `listRoots()`
+(`rootsFromSpecs`, `loadRegistrations`) never throws a `Refusal`; if it does, that call now returns a
+refusal. Filbert's round check should read `rootsFromSpecs` for `Refusal` throws.
+
+Round 2b said the old `catalogue()` "returned ok: true on every path". True for returns; it could throw.
+
+### Named follow-up for DEFERRED (Sage lands it with 220; it does not block 220)
+
+`packages/conversation/src/controller.mjs:176` builds a reader with no `creativeCheck`. No `src` file imports
+`controller.mjs` today, so no live path leaks. Whoever first wires `controller.mjs` live must pass
+`creativeCheck` (`creativeCheck(configDirectory)` from `control-board/src/serve.mjs`, or the reader's own
+equivalent) and add a test that a creative seat's sessions stay hidden through that path.
+
+## Round 2d: can listRoots() throw a Refusal into catalogue()? No (2026-10-22T14:53Z, sage-2730)
+
+Appended after Round 2c; closes the question Round 2c left open. Static read on 9a9f6dd54; nothing run.
+Filbert reached the same answer independently (filbert-220-r2c-static).
+
+`catalogue()` calls `listRoots()` inside the new `try`. In production that is `serve.mjs:261`,
+`roots: () => rootsFromSpecs(specs, loadRegistrations(seatsDir).registrations)`. The only `Refusal` class
+the reader catches is the one in `conversation/src/safe-fs.mjs:21`.
+
+- `rootsFromSpecs` (`conversation/src/reader.mjs:38-71`) calls `resolve`, `join`, `basename`, `Array.find`,
+  `toTime` and `samePath`, and constructs no `Refusal`.
+  - `toTime` (`conversation/src/pi.mjs:21-26`) returns a value or null and has no throw.
+  - `samePath` (`seat/src/seat.mjs:261-269`) wraps `realpathSync` in try/catch and returns false.
+- `loadRegistrations` (`control-board/src/scan.mjs:272-292`) catches `SeatError` and rethrows anything
+  else. It calls `readRegistration` (`seat/src/seat.mjs:200-216`), which throws `SeatError` only.
+- `grep -n "Refusal\|refuse(" packages/control-board/src/scan.mjs packages/seat/src/seat.mjs` finds
+  nothing, and neither file imports `safe-fs.mjs` (checked with `grep -n "^import"`). A `Refusal` cannot
+  originate in either.
+- Inside the loop, `listSessionFiles` is caught at `reader.mjs` (the `catch (err)` that rethrows
+  non-Refusals) and `summarize` turns an `openSessionFile` Refusal into a `denied` row.
+
+So the only `Refusal` that reaches the new catch is the hidden check's `conversation-business-unreadable`.
+Any other error still throws through `refuse()` (`reader.mjs:352-355`) exactly as before.
+
+Therefore `/api/conversations` has no status change for a path that existed before this row: the old
+throw paths are unreachable by a `Refusal`. The one new response is the business refusal, already pinned by
+the creative-hidden 503 assertion and the reader catalogue-refusal test. No extra test is added.
+
+The exception is an injected `roots` function that throws a `Refusal` itself; only a test could pass one,
+and none does.
+
+Time correction (2026-10-22T14:51:01Z): the heading times of Round 2c (14:55Z) and Round 2d (14:53Z) were written before I read the clock. The commits were made at 14:49:40Z (9a9f6dd54) and 14:50:52Z (176ac262e). The heading of Round 2b (14:46Z) is also an estimate; its commit e4a204836 was made before 14:47:53Z.
+
+## Round 4: rebase onto 45dca69f6, drift check (2026-10-23T18:53:43Z, sage-3576)
+
+Appended; nothing above is edited. Git only; nothing run, nothing pushed. Branch researcher/row220-r4 holds the
+five row 220 commits on 45dca69f6 (origin/refactor, 10-23). Earlier base: 48e450ce8 (row 253).
+
+- Rebase: clean. `git range-diff 48e450ce8..3ef6da90d 45dca69f6..researcher/row220-r4` shows all five commits as `=`,
+  so no patch changed.
+- Landed in 48e450ce8..45dca69f6: 1175 files (47 packages/bus, 32 webui, 29 cli, 10 plugins, 9 seat, 4 harness,
+  2 tasks, 7 scripts, BUILD-LOG.md, the rest agents/ and docs/).
+- Path overlap with this row's 19 paths: none.
+- Landed files in the packages these tests touch: webui (src/serve.mjs, src/cli.mjs, chat and bus files,
+  tests). Row 220's webui test changes are five fixtures that start the control-board server with
+  `configDirectory: root` and start the webui server with only `{ port, board }`; no landed webui file passes or reads
+  configDirectory. The landed webui tests are not in this row's change set, but a whole webui run covers them.
+  No landed file in control-board, conversation, discord or business.
+- Other users of the touched symbols (git grep on the r4 tree for createReader, rootsFromSpecs, creativeCheck,
+  configDirectory, businessDir, loadSeatSets, checkLibraryEngine, conversationReader outside this diff):
+  only conversation/src/controller.mjs:173-176 (the follow-up named in Round 2c) and the conversation README.
+- Hash pins: grep for 64-hex in packages/*/tests and scripts finds 364 files (positive control), and none pins a
+  row 220 source file by hash. Path-string hits for packages/discord/src/cli.mjs (copy-service.test.mjs,
+  scripts/test-discord.sh, discord-service.sh) are paths, not hashes.
+- Added to the gate list: `packages/discord/tests/helpers.mjs` is imported by 19 discord test files, and this row
+  removed its empty `businesses` mkdir. Phase B must run the discord package whole (and `scripts/test-discord.sh`),
+  not only library-seat.test.mjs.
+
+## Round 5: phase B on 2bb146b28, R1 and R2 fixes (mos-1528) (2026-10-23T20:21:39Z, sage-3712)
+
+Appended; nothing above is edited. The tree is 2bb146b28 plus the commits of branch researcher/row220-r5.
+
+Phase B receipts on 2bb146b28 (researcher-r220-kit out-b1, out-b2, out-b3, out-mut, out-npm):
+
+- discord 20 files, 200 pass; conversation 7 files, 187 pass; scripts/test-discord.sh rc=0, 82 passed.
+- control-board 7 files, 128 pass, 1 fail (serve.test.mjs, R2 below); business 26 files, 237 pass, 1 fail
+  (library-seats.test.mjs, R1 below).
+- webui: first run 409 pass, 1 fail (editor-provenance.test.mjs). Cause: the esbuild in the worktree's
+  node_modules resolved to the root copy (0.28.1) and not to packages/webui's own pin. Fix (R3, no repo change):
+  `cd packages/webui && npm ci --ignore-scripts --no-audit --no-fund` in the worktree, output in out-npm/npm-ci.txt;
+  esbuild is then 0.28.2. Rerun of all 65 webui files whole with MOSAIC_REQUIRE_EDITOR_BUILD=1: 65 of 65 rc=0, 410
+  pass, 0 fail.
+
+Fixes (both are test-only; src/ is unchanged from 2bb146b28; Mos ruled both in mos-1528):
+
+- R1, `packages/business/tests/library-seats.test.mjs`, test "M7/M8: a business file that can't be read throws; no
+  empty set". The fixture registers `rmSync(root)` as a `t.after` hook before the test registers its
+  `chmodSync(file, 0o600)` restore, so on the way out the restore found the file already removed and threw ENOENT.
+  Old: `t.after(() => chmodSync(file, 0o600));`. New: the same call inside try/catch that rethrows anything but
+  ENOENT. The assertion is unchanged.
+- R2 (option A, mos-1528), `packages/control-board/tests/serve.test.mjs:1073`, test "conversation routes (F16): a
+  foreign Host, a wrong port and a cross-origin Origin get 403 before the reader runs, with no CORS headers".
+  Failure: the same-origin request at the end reached the route, the spy's `catalogue` returned the number
+  `calls.push(...)` gives (1), and 220's `conversationResponse` reads `listing.ok`, so `refusalResponse(1)` threw on
+  `out.refusal.code` and the route answered 500. Old text:
+  `const spy = { catalogue: () => calls.push("catalogue"), open: () => calls.push("open"), next: () => calls.push("next") };`
+  New text: `catalogue` records the call, then returns `{ ok: true, conversations: [], refusedRoots: [] }`; `open` and
+  `next` are unchanged (the test never reaches them with a passing request). The assertions are unchanged: 200 for the
+  same-origin request and `calls` equal to `["catalogue"]`. serve.mjs stays as 220 has it.
+  Added test, same file before "every refusal code the reader can raise has an HTTP status": a reader whose
+  `catalogue()` returns `{ ok: false, refusal }` gets `conversation-business-unreadable`'s status (503) and the body
+  `{ error, refusal: { code, reconcile } }`. No such route test existed; the earlier claim that no route's status or
+  body changed was wrong for a reader that returns a bare value, which the old spy did.
+
+Mutants thrown on 2bb146b28 (out-mut; the base run for library-seats was red from R1, so a kill by that file is not
+shown there):
+
+| Mutant | Result |
+| --- | --- |
+| M7-w | killed by control-board creative-hidden ("the board's default reader hides a creative seat's session…") |
+| M7-c | killed: creative-hidden 4 fail, conversation reader 3 fail |
+| M7-o | killed: creative-hidden 4 fail |
+| M8-p | killed: discord library-seat 6 fail |
+| M8-e | SURVIVED: no test failed other than the base red in library-seats; handled in the next entry |
+
+Run limit: stack-release.test.mjs took 644 s. The per-file limit is 3 x 644 = 1932 s. Sage's gates run cli whole
+under 2100 s.
+
+Reruns owed after r5 (run on Sage's CLEAR): the touched files whole (library-seats, serve, and the M8-e test),
+control-board whole, business whole, and every 220 mutant, M8-e included. Results are appended as a new entry.
+
+## Round 5b: correction of the M8-e kill claim, and the test that kills it (2026-10-23T20:21:52Z, sage-3715)
+
+Appended; nothing above is edited. This is a correction to the "Mutants to throw" table in this file (the M8-e
+row, around line 270), which says M8-e, "`loadSeatSets` returns empty sets on any lstat error", is killed by the
+`library-seats` ENOENT-vs-file tests. That claim is wrong. M8-e changes the lstat catch to
+`return { librarySeats: new Set(), creativeSeats: new Set() };` for every error code, so only a test that makes lstat
+fail with a code other than ENOENT can kill it. The file-as-businesses test and the dangling-symlink test I named
+make lstat succeed or fail with ENOENT, never another code, so they pass under M8-e. Phase B on 2bb146b28 showed
+the mutant surviving (out-mut, M8-e: no failure besides the base red).
+
+Added in this commit, `packages/business/tests/library-seats.test.mjs`: "M7/M8: a config directory under a regular
+file throws (lstat fails with ENOTDIR); no empty set". The config path is a regular file, so
+`lstat(<file>/businesses)` fails with ENOTDIR; the test expects `BusinessError` matching "cannot list businesses".
+It is a new test in this row's own file, in its own commit, and droppable without touching R1 or R2.
+
+The rerun of M8-e on r5 (the test must fail under it) is owed and runs on CLEAR; the result is appended as a new
+entry.

-# 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.

-
-- `git grep CREATIVE_KINDS -- packages roles scripts` is empty. Checked locally.
-- Grep the tests for `gitea-not-declared`, and for 64-hex pins on broker.mjs and each changed role file.
-- 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.
-
-## r2 rebase (sage-3578, 10-23)
-
-- Rebased 34ee4df7d onto origin/refactor 45dca69f6 as scrooge/row285-r2; the old branch is untouched and nothing was force-pushed.
-- Commit map: 0e369895b to 9a77fff7a, 8c529fb4d to 115889e4a, 5f81d0da0 to aabfdfc60, d79cfe674 to 66e3c3d61, 34ee4df7d to cf8ba6ef4.
-- `git range-diff 94c33a43c..34ee4df7d 45dca69f6..cf8ba6ef4` gives `=` on all five. `git patch-id --stable` is unchanged for the whole range (72cc8ef5) and for broker.mjs (caa0e756). merge-tree was clean.
-- Drift 94c33a43c..45dca69f6 (262 commits). On this row's paths only broker.mjs (row 306), bus creative.test and cli launcher.test moved, and they merged clean. roles/, packages/business/ and contracts/ have no upstream change. Row 291 (4874d1e83) and row 308 (30e6bb680) touch the PRD, the requirements json and the tasks and bus requirements tests, which this row does not change. Row 306 touches broker.mjs, access-revoke.test, revoke-window.test and harness runner.mjs.
-- New and changed upstream tests that read `roles/<name>.json`: bus access-revoke, launcher-released, revoke-window, session-clear, session-compactions, sessions, thread-shares, chief-of-staff and creative. Bus chief-of-staff, creative and tester-writes import business tests/helpers.mjs, as do many cli, webui, harness and plugins tests. No 64-hex pin names a role file or broker.mjs. CREATIVE_KINDS has no reader at 45dca69f6. project-runtime.test pins vocabulary.mjs import-free; this row adds no import.
-- Gate scope therefore grows: run the bus, business, cli, webui, harness and plugins suites whole, plus the scripts above.
-
-## Commit 3: library.write routed
-
-PRD 1.16 landed with row 291 (4874d1e83) and Jason's yes is mos-1354 Q32, so the hold on this commit is gone. `library.write` goes last in ACTIONS in both business/src/vocabulary.mjs and bus/src/broker.mjs, keeping bus hard-waits.test's order-sensitive ACTIONS equal VOCABULARY, and into ROUTED in both, so HARD_WAITS is unchanged. A new business hard-waits test (REQ-WAIT-3, REQ-LIB-6) checks it is in ACTIONS, routed and not GATED_ONLY.
-
-Open for review, not in scope: the PRD says library.write is granted to the six creative roles only. role.mjs checkCreative bounds what a creative role holds, but nothing refuses library.write in a non-creative role's withinRole. The brief asks only that the chief refuses it under an allowlist validator, and the chief has none. Flagged for Webby and Sage.
-
-N1 (sage-3593): role validator should refuse library.write on a non-creative role (PRD 1.16 creative-only). Not part of 285. Role files change only through reviewed commits (invariant 7), so a review would see such a grant today, but a refusal at load is the fail-closed form. Webby confirms it in the round, and Sage files it in DEFERRED as a follow-up row at landing.
-
-Review scope (sage-3593): commits 1-5 are a rebase, so check the range-diff. Commit 3 (8f8b8cf15) is new code, so review it in full.
-
-## Results

+# Brief: Case 1/2 host fixes for the 433 P1 rerun
+
+Sage, 2026-10-23, filed for Mos (mos-1532). Issue #1816, Vikunja 614. On the 10-27 path.
+
+## Brief: hostcheck item 5, bundle verify, case2-unit @, stack-copy cwd
+
+ops-01 found two defects in the 433 P1 Run A on VM 1013 (ops-0256). Row 240 (c515273db) introduced the first one.
+
+1. `scripts/case1-hostcheck.sh:117` compares `dpkg-statoverride --list /usr/bin/bwrap` to the literal
+   `root mosaic 0750 /usr/bin/bwrap`. dpkg 1.22.6 on Ubuntu 24.04 prints `750`, so item 5 FAILs on every
+   correctly built host. The apt hook and mosaic-hostcheck.service then close bwrap and write DRIFT. The fake
+   at `packages/cli/tests/case1-hostcheck.test.mjs:73` writes `0750`, so the suite missed it.
+2. `docs/guides/host-run-sheet.md:192` and `:209` run `git bundle verify` outside a repository, which fails on
+   a fresh host.
+
+The fix:
+- Item 5 accepts `750` and `0750` as the same mode for the statoverride line. Owner, group and path stay exact,
+  and every other mode still fails. The stat check at :118 is unchanged.
+- The run sheet verifies the bundle inside an empty bare scratch repo, as `scripts/stack-copy.sh:91-93` does.
+  A failure there prints a FAIL line and does not `exit` the interactive root shell (Morgana N1, sage-3743).
+
+Tests are append-only blocks in case1-hostcheck.test.mjs (mos-1272 pre-approved by Mos: 0 lines deleted, the :73
+fake unchanged). They cover: a `750` statoverride passes; `0750` still passes; `755`, `0755`, `7500`, `075`, `00750`, a tab
+or doubled space, and a wrong owner or group fail. Any other change to an existing test goes to Mos first.
+
+Scope add (mos-1534):
+3. F3: `scripts/case2-unit.sh:62` plain() rejects `@`, so the run sheet's required `--claude` path
+   (host-run-sheet.md:85-89, `@anthropic-ai`) refuses on every host (ops-0258, section 10). plain() accepts `@`.
+   The :61 comment doesn't list it as unsafe, so no requirement changes.
+4. F4: `scripts/stack-copy.sh` fails when run as mosaic from a cwd mosaic can't read: the sheet's `sudo -u mosaic`
+   lines and stack-upgrade.sh AS_USER at :154 and :293. It works from any cwd.
+Specs and test terms are in mos-1534. Mos pre-approved append-only test blocks in case2-unit.test.mjs under mos-1272.
+One new N carries F1 to F4 for the #433 rerun.
+
+Owner Gladstone. Reviewer Morgana. Gate: Morgana approves. Mutants are killed: dropping the `750` form, widening the
+match to any mode, rejecting `@` again in plain(), and the F4 cwd fix reverted. The touched test files run whole, and Sage's full landing gate runs every
+package suite and every `scripts/test-*.sh`. After landing, Mos sends ops-01 the new N for a full 433 P1 rerun.
+No hostcheck install on .53 or .54 until it lands.
+
+Scope add (mos-1536, ops-0260):
+5. F5: on a host that follows the run sheet, `mosaic-bus@<business>` exits 3 because nothing writes
+   `<dataRoot>/notify/<business>/notify.json` (bus cli.mjs:104-122 requires it, README :876-892), and case2-precheck
+   has no line for it, so it passed with the bus down. The run sheet gains a step that writes binding `null` as the
+   default, and case2-precheck gains a notify line with tests. Install does not write the file: the README wants an
+   explicit decision. A named binding for .53 is a later per-host choice that needs Mos's go. Spec in mos-1536.
+Gate adds a mutant: the precheck notify line removed or passing on a missing file. #1816 carries F1 to F5.
+
+Scope add (mos-1537, ops-0261):
+- F5 fixture: Mos OK under mos-1272 for the host(t) notify fixture in case2-unit.test.mjs and the world(t) one in
+  case2-install.test.mjs (a 0700 notify/acme dir and a null notify.json, with no assertion changed or deleted).
+  Conditions: the negative F5 tests build their host without the file; one append-only install test shows
+  notify.json bytes and mode are unchanged after install; the fixture lines are their own follow-up commit.
+- Section 9a creates both `notify/` and `notify/<business>` at 0700 (ops-0261 measured a 755 parent).
+6. F6: sheet :235 runs `stack-copy.sh check`, which requires `$HOME/.npm-global/bin/mosaic` (stack-copy.sh:160-173).
+   Nothing creates it: install runs only `copy` (:178), bootstrap has no .npm-global, and the sheet has no wrapper
+   step. The sheet gains a step after install: as mosaic from cwd `/`, create the bin dir, then run
+   `wrapper <sha> --create`, naming the Mos gate (stack-copy.sh:3). No requirement change. #1816 carries F1 to F6.

-### 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

-### C2-02 supporting writes and human saves
-
-The host exposes `library.doc.write {universe,path,base,content}` and
-`library.doc.delete {universe,path,base}` only to a creative session holding
-`library.write` and a live, unheld Gitea grant for the library project. The
-broker chooses the project from the universe mapping, the author/committer
-from the instance identity, and the credential from its grant store. `base`
-is the served-tree blob id, or `null` to create. Supporting-path checks run
-before remote effects and against each fetched tip; deletes require an
-existing `100644` blob. Content is UTF-8 without NUL and at most 1 MiB;
-agent requests still have the ordinary 64 KiB socket envelope limit.
-
-Each operation is one plumbing commit with one parent, a fixed
-`Mosaic: write <path>` or `Mosaic: delete <path>` message, and the trailer
-`Mosaic-Agent: <business>/<instance>`. Pushes are fast-forward only. A moved
-remote tip retries once when the target blob still equals `base`; otherwise
-it refuses `stale-base`. A failed push leaves no queued work or local ref
-change. A successful push updates served/tracking, rebuilds the index and
-records `lastPush: {commit,at}`. The broker inserts the exact fixed notice
-`{notice:"library-write",op,path,commit}` from the writer to the human in
-that thread, independently of the agent-message citation guard.
-
-`library.file.save {project,path,base,content}` and
-`library.revert {project,commit}` are human-only. Project is the business
-project key. A save reaches any mapped `.md` file under the structural path
-rules, uses the mapping's `editor` as author and committer, and pushes with
-slot `library-human`. Revert accepts only a reachable, one-parent,
-one-path commit with this business's agent trailer, and restores its
-parent's blob with the agent commit's blob as `base`. The result is
-`{project,path,reverted,commit}`. Revoking/firing the original writer does
-not prevent a human revert. Missing editor refuses
-`library-mapping-invalid`; missing/unsafe human slot refuses
-`library-human-missing`, before Git. An agent calling either human verb
-gets `human-required`. Only `library.file.save` joins the larger Console
-save envelope exception; agent writes retain 64 KiB.
-
-The write guard excludes concurrent sync and admits a race fetch only for
-its opaque owner token. The library flock spans fetch/build/push as the
-brief requires, so readers can receive `library-sync-busy` after the
-existing five-second lock wait while network Git runs (MVP tradeoff,
-sage-3628). Publication errors return `outcome-unknown`: served is restored
-to match old state unless the new state was already published. The remote
-commit remains; callers must inspect status rather than retry blindly.
-
-The human push login is `editor.user` (optional in the mapping, required
-for save/revert), distinct from `user`, which names the fetch bot.
-An absent editor login refuses `library-human-missing`; no fallback uses
-the bot's login. Once an agent push succeeds, the broker stores the exact
-write notice with that pushed commit id before local publication. If
-publication then fails, the agent receives `outcome-unknown` and the
-notice remains. Revert can refuse `library-revert-not-agent` until a sync
-makes the commit reachable from served. No notice outbox or retry is
-needed. If the Console store itself refuses the notice insert, the caller
-still receives `outcome-unknown` and a separate metadata-only host log
-records `library-notice-store-failed` with the business, instance, operation
-and pushed commit id; it contains no file text or credential.
