Untested: record row 288 fresh candidate on landed row 283 (#1793)

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

 2026-10-22 13:10 UTC | Sage | Rows 278 and 281 LANDED. Before: refactor at 6af85df4b (V502). Row 278 (#1783, Gander, Webby): the Console Agents view shows thread claims in their own section. It landed as 385a7194c at 12:39Z, ff, 9 commits, manifest 8fa859a0. Run 3 was green: bus 793, webui 345/0/1, ten shells 425/0 under the 3x limits (mos-1275), M1-M6 killed. Runs 1 and 2 were void, on fixture fixes 964b6b184 (placed by Sage) and 9696d1fcb (ruled by Mos, mos-1275). Webby approved (c30588, rev 3200). Done rev 3202, #1783 closed c30589. Row 281 (#1786, Megavolt, Dewey): a fire or a delete revokes the instance's host and Gitea grants. It landed as e479521d3 at 13:06Z, ff, 17 commits, manifest b73d4c81. Slot on 7979fb41e: bus 819, business 231, cli 837, dewey-bus 76 with the Docker gitea-grant test, shells green, M1-M22 killed. The M1 hang was fixed at its cause in b4a (mos-1273). Dewey approved (c30614, rev 3207). Done rev 3209, #1786 closed c30621. Skips on both: test-task's row 244 live-provider pair and test-queue's canonical-root check, plus webui's esbuild rebuild test on 278. After: refactor at e479521d3. DEFERRED moves the grant gap to Done and opens Dewey's N1/N2 text gaps. LIVE is still 86f95bb27.
 
 2026-10-22 14:18:23 UTC | Sage | Row 264a LANDED (#1769, Gizmoduck, Duckworth): sessions per thread, schema 3k-3l. Before: refactor at e479521d3 (row 281). It landed as 84f53540d, ff, 21 commits, manifest 257408e9 (Duckworth approve rev 3214, comment 30640). Gate r13 on 2cc34aef8: 20 touched files, bus 827, cli 837, webui 345/1 named skip, ten shells under 3x limits, mutants M1-M4 killed on assertions. Corrections on the way: the kit stopped on first red, so four reds surfaced one at a time. r10 later3l missed a trigger (mos-1276). T2 had failed since r2 because refusals log action.refused (mos-1277, my sage-2257 wording). threads.test:341 kept the old trigger text (mos-1278). M2 was caught by the store trigger before any assertion, so it now drops the trigger too (mos-1279, four files with the SCHEMA_SHA256 pin). Deferred: actor_run pin binds row 269, esbuild skip to a later gate, session-scoped user reply binds row 272. No live change; LIVE is still 86f95bb27.
+2026-10-21 21:24:47 UTC | Gander row253 #1758 design r1 | Investigation began21:12Z under sage-2162; recorded now. Before: case2 installer still renders tester TCP and case1 acceptance requires it. After: proposed design covers socket marker migration, actual configured dataRoot within unchanged hardening, target-uid metadata queries, kernel-peer acceptance observation and explicit same-uid residual. Initial inventory saved; no passing final static-check claim, product edit, test, host or live action. Duckworth design review precedes code.

+### 2026-10-21 row253 implementation prepared, gate pending
+
+Gander: after Duckworth-0100 design approval with C1-C5, prepared the two host-script socket migrations, fake fixtures, updated retirement docs and 33 unique change checks. Static syntax/diff and source inventory checks pass; behavioral tests have not run. Sage-2191 queues the requested full scope and will send CLEAR. No host, unit or live config changed.
+
+2026-10-22 02:13:30 UTC | Gander row253 C4 committed candidate, gate pending | Sage-2335 explicitly directs committing runnable source and tests before the whole gate. The repair implements the approved after-uid supervisor with separate inner/outer bounds; the static packet is b64aa316a. Current repaired bytes have run no syntax check, test, probe or host experiment. Earlier static syntax results apply only to the old build. Results from 8a8df4171 are historical and do not carry. Duckworth static verdict and Sage CLEAR precede all gate execution. F5 is row276 / #1781 in DEFERRED.md.

After: design draft on gyro/editor-design compares three editor approaches, records WordNet source/license/size, folds the pane/pin model and specifies guarded context/proposal APIs, DesignCraft handoff and seven proposed briefs. Q196 changes the basis to a Word-like interface. Verification so far: editor/provenance checks 10 pass, 1 explicit rebuild skip (pinned esbuild absent); brief fields, unique headings and 11-line checklist checked. Product, queue and live state unchanged. WordCraft scratch evaluation is being incorporated before publication. Review and Jason choices remain open.

WordCraft web 44,179,239 bytes, identical twice; measured comment/footnote conversion limits recorded. Seven briefs and 12-line checklist validated. Fresh editor/provenance: 10 pass, 0 fail, 1 explicit rebuild skip (esbuild 0.28.2 absent). CI queue guard identity gyro/purpose push returned documented degraded-pass (exit 0), CANNOT_ASSERT credential-unresolvable, scratch audit gyro-q195-ci-queue-audit.jsonl; no fallback or CI-green claim. Documentation-only candidate for Mos/Fenton review, no source, queue or live changes.

+2026-10-22T16:06:34Z | Q195/Q196 design review fixes, #1752 / Vikunja #448, mos-1300 / fenton-0004 | Before: draft 105811400 had owner-only thread wording, stale source positions, two mismatched seat/model assignments, an assumed library save boundary and 12 owner questions. After: grant-aware pin validation and stale/revoked access redaction; references refreshed against aca16404c, including public/bus.js and README offsets; Sage assigns model-only seats; unimplemented library.file.save/C2-11b brief blocks book editing; tabs explicitly cover 62-76rem; J7 stricter context choice recorded; pronouns removed; six owner questions. Static docs/source-anchor checks only, no builds, product suites, MVP gate slot or live action. Fenton re-check pending; O3 and both companion folds retained.

+2026-10-22T16:09:56Z | Della mos-1303 / Vikunja 460 Q217/Q222 revision | Before: Q1/Q2 open and Q3-Q7 phrased as Jason questions. After: Jason-created InMotion/woltje.com ingress recorded; per-source mailboxScope defaults none with human-only CLI then Console writer and named default/change/agent-refusal tests. Q3-Q7 settings/defaults/owners documented; no new external decision required for default development, conditional provider/spend/exposure list retained. PRD/grant/data.delete/live gates preserved.

Restored explicit Jason-approved PRD gate; no Q211 waiver inferred. Named tunable parser/attachment settings, defaults and schema/test review ownership of resource bounds; E04 checks changed values and bound refusals. Clarified Q8 extraction stays Jason choice. Docs-only checks, no product/live action; focused review before Sage handoff.
+
+2026-10-22 13:06 UTC | Megavolt | Row 281 (#1786) build. Before: a fire or delete left host_grants/gitea_grants rows, the host line and the Gitea token live. After: step G in broker.mjs revokes them in a detached job per agent (the host line first, then Gitea local-first with an admin preflight); a refusal is grant.revoke.refused plus a human message; open grant decisions are in the set; a raise for a fired agent refuses instance-fired. Tests T1-T14 (bus fire-revokes-grants, lifecycle-revoke, grant-executor, gitea-grant; cli lifecycle). Gate on 7979fb41e: base 121/121 + 24/24, 29 anchors, M1 exit check rc1/17, M1-M22 22/22 killed, dewey-0840 files 76+14+23, bus 819, business 231, cli 837, ten shells rc 0 under the mos-1275 limits; skips: test-task row 244 live-provider pair, test-queue canonical-root check. Corrections: the first base run on c174f37ac went red on five first-run test defects (b3, test only); the first mutant run on 06ee5ed6b hung on M1 because T6c's held loop never ended (b4a fixed the teardown, and the runner now has timeout -k 10 180 and an exit check without --test-force-exit).
+
+2026-10-22T16:36:30Z | Della row224 C2-05b #1725 preparation | Before: C2-05a queries exist at 4f3fbc25a but no broker lookup verbs or typed tools. Scope: broker/tools plus Sage-authorized runtime/bundle integration, tests and docs. Existing human-only library reads retained; five agent queries require a live holder and trusted configured source. Code/docs only under row253 gate; no Node/test/push/claim. Runtime ownership coordinated with Rocko219/Huey272.

After: fast-forward of 4 commits, a cherry-pick of the gated 01983cd3f..9bb406c6c (range-diff 4/4 equal, patch-ids equal, the 4 manifest blobs equal; the base moved only by the #1797 brief, which no test reads; no open branch touches the manifest). Duckworth APPROVE c30849 rev 3356; done rev after the note. N1 (any-business refusal untested) DEFERRED. No live change. Correction: my first 207 review request ran under timeout 120, which killed it while it wrote the outcome; the comment (c30841) had posted, so I removed the dead lock and resolved it at rev 3350.

+2026-10-22T23:03:39Z | Gyro Q195 O2 rewrite, #1752 / Vikunja #448, mos-1356 | Before: landed O3 design 95e3f7166/blob 4cb59999. After: Q231/Q233 full WordCraft O2 design on gyro/editor-o2 from refactor c4f77373f; canonical git DOCX, original Markdown/wiki preservation, human cadence default 0 with instant accepted-save commits, full rich-feature first slice. Ten briefs include independent source/dependency security clearance before any build queue entry, exact editor-only CSP approval gate, restricted source/build/bridge, separate reviewed DOCX citation gate and flags-only agent access. Existing Case 2 semantics unchanged; any integration requirement change goes through Mos to Jason. Static checks: ten briefs/seven fields, independent reviewers, unique anchors, current source/base/blob pins, docs scope and append-only logs pass. No builds, browser/worker runs, code, queue or live changes. Fenton review pending; CSP and implementation gates remain closed.

+2026-10-22T23:09:38Z | Gyro Q195 O2 fenton-0006 fixes | Before: e012bab0b left stale-source ambiguity, incomplete migration/shipping ownership, undefined typing transactions and an unmeasured CSP gate. After: D12 explicitly routes superseded-source/C2 reply notices to Mos/Jason and refuses adoption before W4b/notice path; Q2 remains open. F2-F6 add schema-edge placeholders and restore-accounting files, shipped runtime data/writing closure with no sandbox store mount, per-chapter DOCX and 2s-pause/15s-span save groups, volume/latency/growth gates, split-run clickable wikilinks and historical Obsidian graph warning, and S0 isolated existing-artifact CSP measurement before exact-header approval.

+2026-10-22T23:10:14Z | Gyro mos-1358 ruling recorded | Q36 / Vikunja 562 keeps C2 superseded notices OPEN with Jason. Markdown adoption refusal until W4b PASS is now a separate settled Mos build-order ruling, not a Jason question. D12 and Q2 distinguish them; no notice build authorized.
+
+2026-10-22T23:13:27Z | Gyro Q195 O2 fenton-0007 F7/F8 | Named human-only editor.saveGroupPauseMs=2000 and editor.saveGroupMaxMs=15000 with integer/range/cross-field validation and W3a UI/CLI refusal tests. W3b owns production adoption refusal until W4b; isolated fixture conversion remains testable without request-flag bypass. W4b owns adoption module/API tests and reviewed lifting only with committed-reader/citation readiness and, if Q36 approves, the separate notice row PASS. Q36 unresolved stays closed. Static ten-brief, setting-key/bounds, refusal/lift ownership and two-question checks pass. Docs only; no build, browser/worker run, product/queue/live change. Fenton checks F7/F8 on next push.

+
+2026-10-22T23:23:42Z | Rocko, W4 #1799 | Before, D24-D26 had no separate exact DOCX citation/access contract. After, 15e91538f proposed a versioned schema, parser/story/view/refusal rules, live authorization/sharing and generic/git/session bypass closure, compatibility gates and 22 acceptance rows. Two JSON examples parse, diff check clean; no code or implementation acceptance. Megavolt review pending.
+
+2026-10-22T23:55:11Z | Sage, W4 #1799 docs landing | Megavolt reviewed four rounds (CHANGES 15e91538f, 019a0ea5b, 54246cb32; APPROVE 994c3f7fb, #1799 c30868/c30870/c30876/c30884). Landed here as cherry-picks: docs/plans/2026-10-22_q195-docx-citations.md blob 2af460ab7 and docs/reviews/2026-10-22_q195-docx-citations.md blob bedde1716, both new files. 32 acceptance rows go to W4b; R4-N1 (re-migration after a pre-W4b restore keeps the rotated fence and needs owner confirmation) goes into W4b's brief and A32. W4 is design-approved only: its gate still needs Sage's W4b implementation brief, which waits for S0 (#1798) PASS. Q36 open, adoption closed. Docs only, no test reads these files.
+
+2026-10-23T00:52:58Z | Gyro Q235-Q237 policy rewrite started, Vikunja 571, mos-1366/1367 | Before: approved O2 e36bce352 keeps Markdown originals at their paths and Q36 notices open; landed W4 2af460ab7 has the same boundary. Imported that byte-identical W4 baseline as 1ac76a417, from refactor 062646487, to make the policy-only revision diff explicit. Prepared P1-P6/B1-B4: human one-way per-story import, human-set source-repo archive, DOCX current reader, scoped format map/archived non-canon reads, W7 conversion publication after W4b/approved PRD/10-27 and Jason first-real-book go. Q234 exact CSP, mos-1363 and S0 M1-M14 retained. W4 locator/extractor, shares and restore-fence blocks compare byte-identical to the approved baseline. Scope/source review ongoing; Mos impact map must be folded before Fenton handoff. No build/browser/worker run, code, queue, private-book or live action.
+
+2026-10-23T01:37:07Z | Gyro Vikunja571 final impact-map / mos-1372/1375 fold | Prepared parent/W4 rewrite against brain-redux d183246 impact map at stack 062646487. P1-P6/B1-B4 and engineering Q1-Q16 are mapped to eleven briefs. D9 replaces the earlier private O2-only context/per-document/share model: normal Case 2 access in any authorized thread/room, supporting writes intact, changed policy awaits PRD 1.17 approval. New DOCX story creation has the same opening gate as human per-story import. Host-only push to human-set off-host remote replaces the no-remote ban; remoteURL defaults unset and same-host bare is disallowed. W7 gates on Hermes #423 step5, W4b, PRD approval, post-10-27 and first-real-book go; owns conversion events COUNTED/--events/pre-conversion restore reconciliation, manifest order/next_chapter, creative role cite wording, archive/old-path edits and format/link/citation routing. Store+off-host acknowledgment precedes archive commit/push, then catalogue publication; post-push failures remain resumable pending with pinned source. Current checks pass: complete brief fields, policy/map coverage, exact Q234 CSP, locator/projection mechanics byte-equivalent except explicit authority wording, A01-A35 IDs, immutable map pin, four-doc scope and append-only logs. W4 authority/remote/recovery sections reopened for Fenton; older APPROVE not reused. No product/build/browser/worker/private-book/queue/live action. Earlier entry describing preserved shares/fence applies only to the pre-D9 intermediate draft; D9 now withdraws those unimplemented structures.

B2 follows mos-1379: human-only editor.agentReadComments and editor.agentReadTrackedDeletions both default false, comment/original/markup reads/resolves/index/context refuse when off; final access remains D9 and no role allowlist/per-document grant. N1 staging-ref allowlist and retained private refused/published audit refs; N2 URLs literal with fidelity-report loss and confirmation; N3 future paths marked new or predecessor row; N4 rename/sharing wording fixed; N5 historical thread text not refreshed; N6 protected VM1012 backup cited in P5.

Gizmoduck read it as a race: threadIdle releases the claim, then the launcher sends SIGTERM, and a runner call in between gets not-holder and exits 22. Mos (mos-1411) rejected loosening :229, let 292 count one whole unedited green cli rerun, and allowed one rerun for that exact signature on other gates until the race row lands (hits logged on Vikunja 588). The 10-run diagnostic passed 10/10, but one runner log (r846b8d083502) showed not-holder then exit 22. After: the cli rerun was 910/910. 292 LANDED 6aab979e6 05:18Z (7 cherry-picks, range-diff all =, patch-ids equal), done rev 3447, #1797 closed c31038, Vikunja 588 c891.

Mos ruled landRelease folded in, code launcher-released, and four old-test lines moved to exact values (mos-1414/1415/1416): threads.test:394, runner.test:771-772, land.test:464. Row 294 round 2 stopped at webui G5 granted-user.test:269: max(seq) over an empty events table is NULL.

+2026-10-23T07:11:43Z | Sage, row 294 (#1800) rounds 3-4 and landing, row 219 edits 2-3, R9 transient and row 303 | Before: refactor 09d0d6faf; 294 run 3 on cb1648f3 stopped with 20 cli reds from two causes. A: the stack-release rehearsal fixture copies lacked cli access.mjs and transport.mjs, which 294's config.mjs now imports. B: the B1-B3 boot tests read warnings that now carry the fixture tracker line. Mos ruled A as two copy-list entries and B as a full pin, no filter: a TRACKER const and deepEqual (mos-1419). After: round 4 8616b9a4f, manifest a1ff5d67, Duckworth APPROVE c31053 rev 3469 with C1/C2. Run 4 from npm ci green: webui 365, cli 909, bus 873, 10 scripts, M1-M11 killed. Merged tree d3059c2c3 (11 cherry-picks, range-diff all =, patch-id 8371405a equal): stack-release-external 25/25, stack-upgrade 21/21. stack-release 223/224 on the first run, R9 at :2178: TypeError on join(r.dir) with r.dir null, so rehearse stopped before its directory and the output was lost. R9 passed 6/6 run alone on d3059c2c3, 09d0d6faf and 24b745447. Mos (mos-1422) allowed one unedited whole rerun: 224/224. 294 LANDED d3059c2c3 07:04Z, done rev 3471, #1800 closed c31068, P19 269 c895. Row 303 (#1810, Vikunja 589, brief ad6ca7930) adds an r.dir guard in R9 only. Queue commit 80793d824 (revs 3464-3473). Row 219: Rocko's second edit 7cbd839d0 (mos-1418, Dewey dewey-0883) restarted and went red at thread-launch C2-09a :489 on a legacy history path. The third edit 5f2ef92e5 (mos-1420, Dewey dewey-0885) reads the native session path. 219 now rebases onto 80793d824, because 294 overlaps its webui files. Correction: the first merged-tree check counted on the 292 drift and found an unrelated transient, and my P19 placeholder sed also rewrote the script's own guard line; the guard refused to post, and I restored the line before posting.
+
+Row 299 (573, #1806, Gander, Filbert): before, the P10 band test timed a fault run minus a separate baseline run, and a loaded whole-suite run went red. Mos approved direct timing from host /proc/uptime stamps with ambient load only (mos-1409). After: rebased onto 80793d824 as ffa93b054 (range-diff 3/3 =, manifest 277ace0b unchanged).

Corrections: Launchpad and Gander have no token, and the CLI refuses another seat's token file, so I posted both requests as sage (c31082, c31083). My sage-3265 wording led Duckworth to poll queue show into Gander's slot (07:20Z-07:26Z); I ruled it ambient load (sage-3274).

Row 219's gate went 11/3 in test-release.sh: release activate's health check failed because Docker could not create sage-diag1437_default, since all predefined address pools were used up. Under mos-1437 I reproduced it on clean 07802dc57 (11/3, the same stderr). I then removed 18 unused gate _default networks, and the rerun went 14/0 with the run-task marker ok. Mos accepted the removal and ruled that a probe that can create something waits for the go and a removal waits for the report (mos-1438). 295 (#1801, Morgana, Dewey) round 2 gate on d68b4300d (manifest e94c9aeb) was green.

Brief docs/plans/2026-10-23_gate-env-rows.md names rows for 590 (claude-session slug) and 591 (compose network cleanup), and DEFERRED.md gets 219 N1 (U6). Row 272 (Huey) conflicts with 5fdfd7275 in code, so it moves back to in-progress for a rebase. Its new fallback is bounded to a session.list access-refused on an omitted-session route (sage-3357). Corrections: my network create probe ran before Mos's go, and the removal ran before the report. My first slot-order line put the diag start at 09:44Z; it was about 09:41Z. My 219 push piped its output through grep, but the after-fetch confirmed origin. Queue commit 90633c864 also carries Huey's rev 3510 (272 back to in-progress), and its message names only 3495-3509.

Lookups refuse until one current version is proven; VM1012 restore needs Jason present under Q185. W7 no longer owns hard-waits.test.mjs.

Draft: session CLI, Console chooser with isolated drafts/cursors/receipts, metadata counts and safe-clear operation receipts against Gizmoduck's 0260 contracts; narrow deferred B6 reply fence. Tests authored, not run: Gander row 253 holds Sage's slot; no Node, claim, HTTPS git, push or live changes. This entry records preparation after the first draft, not a green acceptance result.

Added confirmed cancellation through the human channel, cancelled receipt retirement distinction, named refusals and routed-message cancellation output. Before: cancelled was not recognized as terminal; after: draft CLI stops polling and Console shows the before/after retirement outcome. Acceptance remains unverified: no Node/tests/claim/commit/push under Sage's gate. No runtime/lifecycle authority expanded.

Product changes auto-merged; both append-only logs retain the full new base and original Huey additions. Checked landed session.list and clear/cancel/operation envelopes against the wired draft: no incompatible contract change. Historical unavailable-dependency cases stay as stand-ins; actual base supplies counters and lifecycle state. No tests/Node/claim/commit/push while Gander holds row 574 run 2. Existing-test fixture/assertion delta is named in the packet for Mos's ruling via Sage before execution.

Sage explicitly directed committing the rebased draft before testing to preserve it: an untested local checkpoint, no acceptance claim. No Node/test/queue/network/live action. Separate claims and test CLEARs remain pending; old-test delta is with Mos via sage-3144.

+2026-10-23 | Huey | Row 272 early static review follow-up, scrooge-272-early-read-huey-1. Before: a bad-session 404 erased sibling draft/recovery caches, malformed clear/cancel write receipts omitted the audit line, and another session's op key produced an ambiguous error. Draft after: purge only on named thread-level refusals, write one redacted malformed-receipt audit line, and identify key reuse without a write. New browser/HTTP/CLI tests authored, unrun under test hold; approved old-test hunks unchanged. Published 850b22680/round-1 manifest unchanged; follow-up is uncommitted, no acceptance claim.

Static comparison confirms old tests differ only by mos-1388 approved hunks.

+Spec: docs/plans/2026-10-20_case2-rows.md, C2-02; agents/gosalyn/work/case2/DESIGN.md ruling after r11.

+
+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.

+# Row 224 — C2-05b broker lookups and typed tools (#1725)
+
+Owner: Della; reviewer: Dewey. Assignment sage-2795; scope extension sage-2804.
+Base: `4f3fbc25a` (Researcher C2-05a). Branch: `della/row224`.
+Brief: C2-05b in `docs/plans/2026-10-20_case2-rows.md` at `aca16404c`
+and `51cc0445c`; design section 3, 5.3 M3 and 7.2; C2-05a BUILD rulings.
+
+## Execution boundary and progress
+
+Code/docs and local Git only while row 253 holds the gate. No Node (including
+syntax checks), HTTPS Git, queue claim, test or push until Sage's CLEAR.
+Tests are written first; their RED/GREEN runs are deferred, not claimed.
+Queue next is deferred too: its executable uses Node. Sage assigned this row
+explicitly. After 253 and 216 land, rebase under a new branch name.
+
+- Pre-flight: query.mjs consumes `{repo,commit,mapping}`; broker cannot import
+  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.

+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

+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.
+
+Candidate preservation commits are explicitly unrun under sage-2795; they are
+not completion, green-suite or landing claims. No dependencies installed.
+
+Correction: the first committed-range diff --check found a blank line at EOF
+in the new library-tools test, missed while it was untracked. Removed in a
+follow-up local commit; the complete range must be checked again. No tests ran.
+
+## Shared-log receipts for Sage (sage-2815)
+
+The shared logs are unchanged from the base in this row. Sage appends these
+receipts in the landing sweep; they are preserved here, not in the manifest.
+
+For `BUILD-LOG.md`:
+
+```text

Scope: broker/tools plus Sage-authorized runtime/bundle integration, tests and docs. Existing human-only library reads retained; five agent queries require a live holder and trusted configured source. Code/docs only under row253 gate; no Node/test/push/claim.

+
+Local-only draft pins 19c0a7adf/7cf39c390 are superseded by the
+log-free candidate. Saved as local branch della/row224-draft-with-logs before
+rebuilding the unpublished candidate commit; no remote history changed.
+
+## 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.

+# Row284 C2-05c — supporting scope and served-tree blob (#1789)
+
+Owner Della; reviewer Dewey; gate Sage. Build start sage-3658/3660 (10-23).
+Branch della/row284. Original prerequisite base Honker28346bad7ea3;
+merge fc05bcbc3 carries22423816cf28 and2164f3fbc25a intact. Only conflict was
+CLI thread-launch's added footer tests: retained both full test bodies and
+assertions. No prerequisite code copied. Every prerequisite needs its own
+review/mutants/landing under mos1351; rebase after283 lands.
+
+## Execution status
+
+UNTESTED. No Node, node--check, test or mutant run before Sage CLEAR. First
+own commit is the authorized old-test migration; the implementation follows.
+Sage authorizes an immediate untested push. No queue write or shared-log edit.
+224 stays first;284 is critical to Bubba288. T4 for224 is not a CLEAR yet.
+
+## Binding readings
+
+Brief C2-05c at94c33a43c:1737-1789, Q226, sage2918 and mos1330 item3.
+get defaults canon; explicit playground/supporting opt-in; mismatch null.
+Sort full outgoing/incoming lists supporting, playground, canon before paging,
+keep cross-scope links and universe filter. Manuscript stays canon/playground.
+No all/array scope, write tool, guard, mapping or creative-name-count change.
+
+## 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.

+# Target config validation for every key implementation plan
+
+Goal: #1797, mos-1353, brief f0e3dcdf4:docs/plans/2026-10-22_config-checks-any-key-brief.md. Base01983cd3f, branchgander/config-checks-any-key. Reviewer Duckworth. Queue number pending Sage; packet moves to queue-N when assigned. No Node, test or push before Sage gap/CLEAR. Rows270/271/203 land first; rebase under a new branch name before the gate.
+
+Architecture: config_checks classifies missing/parseable/unreadable config independently of console presence. With a loader, every existing parseable config goes through the target's own validate. Missing config passes. Malformed JSON refuses. With no loader, allow only the oldest four top-level keys: configVersion, environment, dataRoot, execution. Evidence: c3d29e796:scripts/mosaic-config.mjs:114, the first loader commit, rejectUnknownKeys; row200 fixture's LOADER_OLD has the same list. A missing loader plus a later key refuses and names that key, without inventing validation support. The legacy public refusal code config-console-key and existing console-specific message stay byte-identical; new non-console refusals name the loader's first diagnostic and preserve restore-config-backup instruction. The target loader's resolved stdout is discarded. Its first stderr diagnostic is reported and may echo an invalid value.
+
+Files: scripts/stack-release.sh config_checks/comment only; packages/cli/tests/stack-release.test.mjs appended regression coverage only; docs/TOOLS.md broadens the current console-only release-check description. Existing row200 tests and assertions stay unchanged. No fixture-module edit, flags, pointers, migration, schema, data, live unit or host change.
+
+Tests to write before implementation, unrun until CLEAR:
+- A target loader rejecting a non-console key refuses activate and rollback before any unit stop/start, pointer/unit/store mutation; one refused log entry; --plan preserves state and lists refusal. Reuse refused() and planOnly(). Use execution, already known to the current loader, to prove console-free dispatch before row270 integration; add compactionReadBytes/compactionStreams cases on final post270 base if needed.
+- An accepting target loader is actually called with validate and the selected MOSAIC_CONFIG, succeeds activate/rollback without console, and resolved stdout is not leaked.
+- Missing-loader target permits oldest-key config but rejects a later key with backup instruction. A stand-in rejecting the existing execution key exercises the generic target-validation branch; missing-loader later-key test may use console until final post270 base supplies non-console new keys.
+- Missing file passes the isolated real config_checks function; malformed JSON refuses there, since load_config otherwise exits before this function. Tests extract only that function and provide copies/path/check_refuse stand-ins, never live state.
+- Existing console-key row200 tests and malformed-load test run whole unchanged.
+
+Mutants, each unique target, syntax preflight and byte-identical restore:
+M1 restores the console-only skip, killed by the named non-console activate/rollback refusal test.
+M2 ignores failed target validation, killed by the same refusal assertions.
+M3 allows a missing-loader target with a later key, killed by the explicit missing-loader regression.
+M4 treats malformed JSON as absence, killed by isolated parse guard test.
+M5 skips the loader for an oldest-key config, killed by accepting-loader invocation witness.
+
+Gate after static review and required rebases: intended RED/GREEN; touched stack-release.test.mjs whole, CLI suite whole and every scripts/test-*.sh whole; M1-M5 with fresh passing controls, no timeout counted as kill, restored bytes/status before next. TMPDIR mktemp-d /mnt/storage/scratch/tmp/gXXX; pipefail/tee and busy check before each start. Node timeout-k10 uses at least3x measured duration plus margin; stack-release prior full receipt around584s implies at least1871s, to be recorded from actual receipts before CLEAR. Shell3x table retained with receipts. No test ran and no behavior passes claimed.
+
+Review focus: parser races after load_config; target stderr naming only the refused key, stdout never persisted; current versus target loader selection; unknown key with no console; missing loader compatibility set from immutable history; upcoming row270 loader-list fixture drift. Final integration audits every test dependency and hash pin against the named base. Session registration remains Sage's.
+
+
+Implementation ready, unrun. Four appended tests cover full activate/rollback refusal and plan; actual accepting validate witness/configpath and stdout nonleak; oldest-only missing loader with both compaction keys; missing/invalid JSON isolated realfunction. Stand-in loaders are ESM, matching .mjs. Every old test byte is preserved as a prefix. Existing console refusal text including missing-loader diagnostic is unchanged. Missing-loader compatibility is top-level key compatibility only; current load_config still validates the whole config before normal release operations. Three-path manifest, no fixture-module changes. Static target uniqueness M1-M5 passes. No Node parse, Bash execution or behavior run. Exact full compaction activate/rollback cases must be added against post270 loader, before final gate.
+
+
+Execution state:
+- [x] Read brief, config_checks and row200 assertions.
+- [x] Pin oldest key set from immutable loader history.
+- [x] Write regression tests, implement bounded scope, prepare unique mutants.
+- [ ] Duckworth static review.
+- [ ] Move packet to queue-N on assignment, rebase after270/271/203 and add full compaction-key cases.
+- [ ] On CLEAR run intendedRED/GREEN, touched whole file, CLI whole, M1-M5, ten shells; commit/push records only when authorized.

+## Duckworth0229 static approval, gate conditions
+
+Source0585b3213, packet e7371025f, manifestd6226d28 approved by static read, note a5a717391:agents/duckworth/work/row1797/ROUND1-0585b3213.md. No runtime proof yet.
+
+C1: after270/271/203 land, rebase under a new branch name and open a new static round. Add exact compactionReadBytes and compactionStreams full activate/rollback refusals. The existing LOADER_OLD uses the current loader plus concat after270, so it is not a pre270 witness; the new test requires its own pre270 stand-in. Reviewer checks the integrated manifest/test before CLEAR. N3 joins that delta: compactionStreams fixture value1024, matching the real type, instead of ['messages'].
+
+C2: every existing B/C1/C release now validates its copied real loader, including external/upgrade suites. Any old CLI red is a change-related suspect and goes to Mos/Sage under mos-1272; no automatic placement as an unrelated fixture.
+
+N1 console plus another refused key retains the old console text by design. N2 missing-loader wording is retained pending final integration review. N4 corrected above: only resolved stdout is suppressed; first stderr may echo a value, so no blanket secrecy claim. No runtime/Node/queue/push authorization is inferred from static approval.

+# Row253 build record
+
+2026-10-21 design stage. Read brief Static check and Gate before starting. Busy check was CLEAR; claimant gander-253-start recorded rev2995. Branch gander/row253 starts from origin/refactor c3d88840c, after196 landed7247d80c7. Plain linked node_modules retained.
+
+Only DESIGN.md and this record/inventory are written. No product code, tests, host config, units or slot files changed. BASE-PORT-INVENTORY.json records the initial source hits; it is not a passing final static check. The final check must classify every remaining hit after implementation.
+
+Design r1 proposes configured dataRoot resolution as the target user, socket metadata plus an isolated system-Python SO_PEERCRED observation, unchanged hardening, P8 migration and honest unnamed P10 same-uid evidence. Duckworth approval is required before implementation. No test slot requested until the final static check passes; every single/pattern run also needs the slot under sage-2142.
+
+## Implementation before slot
+
+Duckworth-0100 approved design r1 with C1-C5. Code and new tests were written after that approval. Tests are written but unrun: sage-2142 requires a slot even for patterns, and the row253 brief requests static preparation before the slot request. Syntax checks and static source inspection only have run. No behavioral passing claim is made.
+
+C1: component containment, dot/dotdot/double/trailing slash rejection and a no-follow component walk. T4 includes middle symlink and sibling-prefix homes, plus protected/private roots. C2: conservative ASCII path alphabet without whitespace; LC_ALL=C makes pathname length a byte count. C3: bash accepts only the canonical two-key string/boolean JSON. Root never imports the copy. C4: GNU timeout owns a process group; output is capped and the wrapper kills remaining group members and waits for its direct child on success, failure or signal. Tests cover a TERM-ignoring reader and a child that closes stdout before its parent returns. C5: both headers name the new unprivileged config query.
+
+N1: deferred the optional broader MainPID TCP inventory. P8 retains the approved main listener plus 7331/7333 check. N2: removed accepted mos-1101 from MARKS and P_PASS.P10; healthy and failed observations both stay unnamed, per sage-2173. N3: sudo resolves through PATH, matching case1's existing fake seam. N4: F11 retains the default DATA_ROOT Discord check; generalizing it to configured dataRoot is a separate F11 follow-up.
+
+The README had three obsolete current-usage passages. They now show the socket marker; the remaining mention explicitly says TCP is retired. No deliberate legacy source or test changed. Acceptance still runs F9's existing builtin-only settings parser as root under its existing pinned-path checks; the new query and fixed-system-Python observation run only as the stack user with env -i. P10 separately checks its parent, final socket, process uids, stable MainPID and metadata snapshots. Its probe sends no application bytes. Hostile same-uid changes before or after that snapshot remain the stated residual.
+
+Static checks: bash -n on both scripts, node --check on both test files, git diff --check, Python AST parsing on the record drivers, all 33 variant shell syntax checks and unique-target validation. All passed. These are not behavioral tests. Five source/test/doc blobs are frozen in CANDIDATE-SHAS.json for the requested slot. UNIQUENESS.json records original and changed hashes for every definition. No suites or checks have run. Driver names, wrapper argv and controller.log avoid the busy detector's patterns; actual commands are loaded from structured JSON only after the busy guard succeeds. Every run uses bash pipefail and tee.
+
+## Every remaining retired-port hit
+
+Static source audit, not a test run. Each remaining hit and its reason follows.

+
+Sage-2191 accepted the requested scope and queued it behind the re-pin, 194, 202 and 254 windows. No CLEAR yet. TMPDIR will be created with `mktemp -d /mnt/storage/scratch/tmp/gXXXXXX`. STATIC.json records final syntax/diff results; no behavioral tests have run. No product commit or push has been made before the applicable suites pass.
+
+Grant sage-2279 run1: both intended RED cases observed. First installer GREEN file 35/1 in 17.231 s: EEXIST in the pre-existing outside-secrets test because the shared hub now creates dataRoot. Changed only that mkdir to recursive; its refusal assertion stays unchanged. No product bytes changed. Recorded old/new test SHA in run1/fixture-fix.json. Harness now explicitly selects TAP for machine counts and supports GREEN-only resume. This is the first unexpected failure; a second ends the window.
+
+Grant sage-2279 run1 ended on unexpected failure 2, reported to Sage and Mos as gander-0073, slot returned 2026-10-22T00:34:10Z. Acceptance whole 27/1 in 41.962 s: the broad new od fake intercepted F3 random-token generation as well as the ELF header read. Narrowed only that fake to -An -tx1 -N4; all other calls exec /usr/bin/od. The 12-hex assertion stays unchanged. Product blobs have not changed during the window. No tests run after the stop, and no checks/full suites/shell files started. run1/SUMMARY.json sums all raw logs; sweep count 0. Need a new CLEAR before any rerun.
+
+Sage-2287 approves both test-only fixture fixes and requests their commit with unchanged assertions. Commit contains the two prepared row253 test files and packet, including both old/new test SHA pairs and raw run1 results. Product scripts, README and root BUILD-LOG remain uncommitted. PORT-AUDIT.md/json refresh current line numbers after the od fake grew two lines. The earlier audit above describes the pre-fix candidate. Next CLEAR scope: both whole touched files, M1-M33, cli and webui whole and ten shell scripts. Intended RED carries under unchanged product bytes; no further test has run.
+
+## C4 static gap and addendum
+
+Grant sage-2297: installer whole36/0 in16.449s, acceptance whole28/0 in37.550s, M1-M33 killed33/33 (bases11.808s, changed runs41.202s), CLI whole755/0 in597.084s. Webui was deliberately interrupted after4.736s for a static C4 gap; it is not a failed test under sage-2307 item5 and has no completed total. Ten shells never started. Slot returned with sweep0 as gander-0076. run2/SUMMARY.json is script-summed from the preserved results and raw logs.
+
+The current outer GNU timeout kills its own group, but sudo(8) Process model documents a pty monitor creating a different terminal session. Signal handling says SIGKILL cannot be relayed. The exec fake does not cover that path. No host experiment ran. Duckworth-0109/0110 at2c49dd80c confirms the static gap. DESIGN.md remains unchanged; DESIGN-C4.md proposes the after-uid supervisor and independent outer bound, states the stalled-supervisor residual, compares runtime options and records the old talk watchdog as a proposed bounded follow-up.
+
+Sage-2307/2312 authorizes writing the fake and addendum without tests. The shared case-sudo-fixture.mjs is now imported by both host-script tests. It preserves exec mode and offers a parent/setsid/catchable-signal hop mode with PID/SID records. A new installer counterexample blocks a TERM/HUP-resistant copy under both modes and checks session/PID cleanup; its explicit fixture cleanup only kills recorded fixture PIDs. This draft fake has not run, and no syntax execution is claimed for it. The two script product blobs remain exactly the granted bytes; test bytes now differ for the draft counterexample and shared seam. No repair is implemented.
+
+The next action is Duckworth's static ruling on DESIGN-C4.md and the fake commit, not a test run. If product changes, the completed gate results are historical only and the whole gate reruns on Sage's next CLEAR. C4 now means killed at the inner bound and root never waits past the outer bound; a stopped/killed supervisor and setsid escape remain the same-uid residual. No root cross-session killer is proposed.
+
+For the static pass, c4/*.sh.txt are non-executable snapshots of the exact granted product source. FROZEN-PRODUCT.json pins their equality to the uncommitted source blobs. They are review records, not an implemented repair or a product commit.
+
+## C4 repair prepared for static review
+
+Duckworth-0111 approves DESIGN-C4.md with C1-C5. The repaired scripts now contain the same inline supervisor payload after the uid drop. It uses fixed validated system binaries, starts a query session without setsid -f/-w, confirms SID equals the child PID from the kernel, reads whole stat files, scans every process group in that session, and reaps its direct child. Query bounds are inner 5 s / outer 7 s; peer bounds are 2 s / 4 s. Separate trusted timeout notices distinguish the outer refusal from a child exit status. Both headers name the bounds and tools.
+
+The shared fake retains exec mode and a separate-session parent mode. Exact inner, outer and output-limit reasons are asserted in both modes. The setpgid child has a comm containing a closing parenthesis, space and newline. Session cleanup checks all members of recorded self-led sessions as well as exact recorded PIDs; exec mode never scans the runner's session. Every fixture cleanup kill checks the recorded SID against the kernel immediately before signalling. The stalled-supervisor case deliberately records the same-uid residual, refuses without using stdout, and performs explicit fixture cleanup. The outer timing slack is 2 s. The post-return polling budget remains 50 x 10 ms.
+
+M1-M33 were retargeted where the repair changed source, with M34-M39 for absent inner/outer supervision, group-only cleanup, unbounded read, dropped setsid and one-copy payload drift. All 39 target strings occur exactly once in a static byte check. These are proposed checks, not kill results. The old runs remain historical evidence only: product bytes changed, so the entire gate must rerun on Sage's next CLEAR after the short static pass. No repaired-source syntax check, test, probe or host experiment has run. git diff --check reports no whitespace errors.
+
+F5 now names row 276 / #1781 in docs/plans/DEFERRED.md (sage-2331). That path will be in the row253 manifest. c4/UPSTREAM-PATHS.json records the requested 968db0bcd..ddfb29af7 comparison and the branch-base comparison. Only DEFERRED.md overlaps upstream since c3d88840c; its current upstream text was preserved before appending this row's entry. The branch-to-refactor comparison also lists the unlanded test files on our side. No rebase was performed.
+
+c4/REPAIR.diff, *.repair.txt and REPAIR-SHAS.json freeze the complete repair for Duckworth's C1/C3/C5 static look. The original c4/*.sh.txt and FROZEN-PRODUCT.json stay unchanged. The runnable product and test files remain uncommitted pending the applicable gate; this packet commit is records only. No node_modules path is included.
+
+2026-10-22 02:13:30 UTC: sage-2335 publishes b64aa316a and explicitly requires a committed runnable candidate before the gate. Accordingly the seven repaired source/test/doc paths, the existing BUILD-LOG append and this record are committed now. All seven bytes still match c4/REPAIR-SHAS.json; this commit changes no reviewed packet source. CANDIDATE-SHAS.json is refreshed for the new gate. MANIFEST.sha256 covers the eight product/test/doc/log paths, including DEFERRED.md. No repaired-source verification ran; the static verdict and CLEAR remain pending, and all old results are historical only.
+
+## duckworth-0112 delta, no runs
+
+B1: both supervisor copies use fork-free IFS= read -r -d '' with content-based EOF/error handling. The 250 ms confirmation budget starts after the first full inventory pass. A deterministic stand-in clock test pins this placement without wall timing or real signals; M40 moves the budget back before pass one. All 40 proposed targets statically occur once. No test or syntax execution ran.
+
+M1: BUILD-LOG.md is removed from MANIFEST.sha256. Its row253 phase lines land as a separate doc-only append after code, preserving newer upstream lines, under sage-2342. The manifest now has seven entries. The initial eight-entry manifest is superseded.
+
+N4: SID confirmation now waits within the existing inner watchdog budget rather than only 100 sleeps. It still refuses a vanished/unreadable child or unconfirmed session, and the independent outer bound remains. N1/N2 are explicitly deferred in the existing F5 entry to row276 / #1781, as Sage rules. No case1 analogue checks were added in this delta.
+
+The required gate base is the refactor tip Sage names at CLEAR, 378a76b85 or later. This delta is prepared on the current seat branch for static review only; no old-base gate is authorized. The final integrated gate candidate will get fresh hashes and integration records before execution. c4/delta-0112/ freezes the seven source/test/doc paths, the delta from aa81ca390, and static uniqueness. Prior frozen packets remain unchanged.
+
+Duckworth-0113 approves 761893dac after git reads only (8d3fa3f20). B1 and M1 are closed; real timing remains unverified until the gate. N5 is harmless diagnostic noise on a vanished stat entry: the input redirection can report before stderr is redirected, and tester_capture discards supervisor stderr. No source change is made for it. N6 is recorded with R3: if the inner watchdog expires before kernel SID confirmation, finish has only the known child PID and kills that PID, not an unverified session. Other members may remain. Root still refuses, discards stdout and waits only within the outer bound. This is an explicit limit of cleanup before session identity is established, not a claim that the session was swept. The independent outer bound does not prove cross-session cleanup. Source/test bytes and the seven-entry manifest remain exactly those approved at 761893dac.
+
+Sage-2463 integration onto 0fa7bf421: new gander/row253-0fa7 preserves both earlier branches. Only BUILD-LOG append conflicted; current upstream remains an exact prefix. README auto-merged with row191 processing controls. Focused row253 tests do not read the changed Console/processing code, but WebUI whole covers it on this base. Only README changed in the manifest; refreshed digest 24b6a01b2ede6f025ec898fa4ec830bb9585ce6151d6298e713e31c7430a502b. integration-0fa7/ records source-only dependency inspection, range-diff and every commit patch-id. No test/syntax/probe ran.
+
+## Re-integration under sage-2659, no runs
+
+New branch gander/row253-385a on385a7194c, rebased source141b79c29. Only the BUILD-LOG append conflicted; kept upstream as exact prefix. Runtime scripts, focused tests and shared fixture match8de88458d byte for byte. DEFERRED/README absorb upstream additions; manifest72a70e99ba0416ceb1f63ed737132ebbeb212332d1441c362b3dfa6c8b00209c. integration-385a/ holds the range-diff, full and no-log patch-ids, upstream manifest diff, test import/read drift and40 unique targets. No test or Node ran.
+
+The focused tests indirectly import Store through CLI helpers, so they read/hash-check current schema.sql and migrations. 264a changes3k-to-3l ahead of this gate and needs a dependency re-check before CLEAR, even if its manifest overlap is empty. Whole stack-release T46 also reads current schema. case2 sandbox availability skip remains named under Duckworth0116 N9. The real Console files moved in278, but the focused tests write Console/config stand-ins; wholeWebUI covers the real changes.
+
+SHELL-LIMITS.json now includes fresh278 run3 receipts. Same ceil(3*longest)+120 formula; foundation maximum39.901s gives240s. window.py uses each recorded whole-shell limit, and driver.py classifies GNUtimeout124/137 as timeout, never kill. No script/product/assertion changed. Historical row253 results carry nothing after C4.

+# Row253 C4 addendum: the supervisor belongs after sudo
+
+Draft for Duckworth's static ruling. DESIGN.md remains unchanged. Authority:
+duckworth-0109/0110, RULING-c4.md at 2c49dd80c, and sage-2307/2312.
+No repaired product code or new test has run. Product scripts still have the
+original frozen bytes; this addendum does not claim they satisfy C4.
+
+## Finding and evidence
+
+The current tester_capture puts GNU timeout --signal=KILL outside sudo, then
+kills that timeout's process group. It works for the exec-style sudo fake.
+sudo(8), **Process model**, says the pty monitor creates a new terminal session
+and forks the command there. **Signal handling** (called Signals in the local
+rendering) says SIGKILL cannot be caught and relayed. Therefore an outer group
+kill does not establish that the query in the new session is killed.
+
+Evidence was a static read of the installed sudo(8)/sudoers(5) documentation,
+then Duckworth's independent ruling against sudo 1.9.17p2. No real sudo, host
+experiment, live unit or live-port experiment ran. The shared fake below is
+written but unrun. It models the session boundary, not authentication or a pty.
+
+## Proposed trusted supervisor and runtime trade
+
+Recommend a reviewed inline Bash supervisor, run **after the uid drop**, using
+root-validated fixed system Bash, setsid, sleep and kill/builtins. These are
+host tools, never binaries or scripts from the selected copy. Resolve system
+symlinks to their real targets; require executable root-owned ELF files and
+safe root-owned ancestors, outside homes. Do not use PATH lookup for these
+supervisor tools. env -i removes BASH_ENV and other injected runtime settings.
+Add setsid to the documented host dependencies. No new configuration knob.
+
+This is a proposal under R1's root-validated system-binary option, pending
+Duckworth's approval of Bash rather than the example GNU timeout. The exact
+inline supervisor must be identical in both host scripts, with budgets and
+command argv passed separately. No helper is imported from the copy.
+
+Alternatives weighed:
+
+- GNU timeout alone inside sudo fixes the session hop but kills one process
+  group. It misses a grandchild that uses setpgid without setsid. It needs the
+  same owned-session cleanup as the proposed supervisor.
+- Validated --node with inline builtins can implement the same supervisor.
+  The installer already validates it. Acceptance deliberately reports unsafe
+  --node paths through F9/F10; making that binary a required trusted supervisor
+  would change those existing outcomes or need another pinned runtime.
+- Fixed root-validated system Python can fork a session, multiplex bounded
+  output and scan /proc cleanly. It is already used for P10, but making it
+  mandatory for the config query changes missing/unsafe Python from a failed
+  P10 observation into a preflight refusal. Preserve that behavior here.
+
+## R1: own a query session, not sudo's group
+
+The supervisor starts in sudo's possibly separate session as the stack uid.
+It forks the query child, then setsid occurs in that child through the fixed
+system setsid binary. The supervisor itself may already be a group leader,
+so it must not attempt setsid in its own process. Disable Bash job control;
+the newly forked child is not a group leader, so setsid need not fork again.
+The child's PID from $! is the kernel session id. No PID comes from copy output.
+
+Run a separate five-second watchdog inside the uid boundary. On expiry, on a
+supervisor catchable signal, on output refusal, and after normal query exit:
+
+1. Scan numeric /proc/*/stat entries for the owned session id. Parse after the
+   final closing parenthesis, so spaces, parentheses and newlines in comm do
+   not shift the kernel fields. Use the kernel session field, not ancestry.
+2. SIGKILL every live PID in that session, including different process groups.
+   Repeat until no running members remain or a fixed 250 ms cleanup budget
+   expires. Never select a process from a different session.
+3. Wait for the direct child and the watchdog. Refuse on a cleanup limit or
+   read/parse error that prevents establishing cleanup. Zombies are not running;
+   only direct children can be reaped here. Tests pin that distinction.
+
+A five-second deadline concerns the inner query. The root-side deadline is
+independent. Query bytes are accepted only after success and completed cleanup.
+The query can never authorize a root kill: its stdout supplies no PID/session.
+The supervisor runs without root authority and kills only its owned session.
+
+## R2: independent root bound and bounded output
+
+Root waits at most seven seconds for the metadata sudo call. Keep GNU timeout
+outside sudo for this separate purpose. Keep the 4096-byte cap plus one-byte
+overflow detection. All partial output is discarded on any refusal.
+
+Give outer timeout its own operator reason, distinct from inner timeout,
+child failure, output limit and cleanup refusal. A child-supplied exit value
+alone must not masquerade as proof the outer timer fired. Capture GNU timeout's
+trusted verbose signal notice separately, with sudo/helper stderr redirected
+away from that channel. The root-owned notice file is outside the user's
+home. Validate the combination of notice and status; no eval or source.
+
+Apply the same primitive to the new P10 peer probe, with inner two seconds,
+outer four seconds, a 128-byte output cap and the existing one-second socket
+connect timeout. Preserve its fixed system-Python safety check and failed-P10
+behavior. All observed stdout still requires successful cleanup and exact
+pid/uid/gid validation. Neither path sends application bytes to the socket.
+
+## R3: narrowed claim and residual
+
+C4 now means: killed at the inner bound, and root never waits past the outer
+bound. A hostile same-uid query can kill/stop the supervisor or setsid away.
+A hang in the trusted supervisor has the same outer-bound outcome. In that
+case root refuses and discards stdout; the separate session may remain.
+This is the existing DESIGN.md:97-99 same-uid limit, not a new closure claim.
+No root-side cross-session killer is added. It would require another row.
+
+The stalled-supervisor fake must prove outer timing, its own refusal reason
+and no use of partial stdout. It then explicitly kills its recorded leftover
+session as fixture cleanup, naming that step as the R3 residual. It must not
+claim the product cleaned that session. Other normal-supervisor cases assert
+no running members of the recorded query session remain after the call.
+
+## R4 and F5: headers and remaining legacy calls
+
+Both headers will name the inner supervisor, its runtime/tool validation,
+five/seven-second query bounds and two/four-second peer-probe bounds.
+
+The old F3 talk path (currently timeout 330 around AS_USER talk) has the same
+sudo session-hop issue. Propose recording it as a bounded follow-up, rather
+than changing it in this slice: it predates the socket metadata/probe helpers,
+drives a 300-second functional conversation and simultaneous F5 scan, and has
+existing stdout/stderr diagnostics. It is not part of the new five-second
+config query. This is an explicit F5 scope choice for Duckworth/Sage to accept
+or reject, not a claim the old talk timer kills a separate session. Likewise,
+the other legacy AS_USER diagnostics are not newly supervised by this row.
+
+## Shared fake and next evidence
+
+packages/cli/tests/case-sudo-fixture.mjs provides the one process-model seam.
+Both existing test files import it. Mode exec retains the prior fake. Mode
+hop keeps a parent, forks through setsid, records kernel PID and SID, and
+relays TERM/HUP/INT only. It cannot relay KILL. The installer draft case makes
+the copy ignore TERM/HUP and block; it checks recorded query PIDs and the
+separate fake session, then explicitly cleans fixture-owned PIDs on failure.
+This is written but not run, and is expected to expose the old product gap.
+
+Before the next whole gate, complete both-mode cases for timeout, TERM/HUP,
+setpgid grandchild, overflow, and the distinct stalled-supervisor residual.
+Both host-script paths use this seam. Add changes for absent inner supervisor,
+absent outer bound, leader-group-only cleanup and unbounded read. The setpgid
+case must kill the group-only change. Record every restore and raw log.
+
+Duckworth reviews this addendum and fake statically first. Product code then
+implements the approved mechanism. All product changes void prior results
+under sage-2307/mos-1200. Only Sage's next CLEAR permits a diagnostic or gate
+run. The next gate is both whole touched files, all checks, CLI/WebUI whole
+and all ten shell files. Existing RED evidence carries only if applicable
+product bytes remain equal. No host deployment is authorized by this packet.

+# Row 253: private tester socket in the host scripts
+
+Gander, 2026-10-21. F27, #1758. Base c3d88840c, after row196 landing
+7247d80c7. Brief: docs/plans/2026-10-21_tester-socket-scripts.md at
+0cdead66c. Reviewer Duckworth; gate owner Sage. Status: proposed, no product
+code or tests changed. Claim gander-253-start is queue rev2995.
+
+## Outcome and scope
+
+The factory installer renders a bare --tester-socket flag instead of a TCP
+port. Case1 acceptance consumes that saved form and examines the private
+listener without claiming that a private pathname defeats hostile same-uid
+processes. The library profile still has no tester. No .53 or .54 host may
+take a copy carrying196 before253 lands, per mos-1198.
+
+Change scripts/case2-unit.sh, scripts/case1-accept.sh and their two existing
+CLI test files. Their comments/usage and fixture docs move with the code.
+Do not edit the deliberate legacy paths named in the brief. No runtime bus,
+Console, role, grant, control-board, dependency or systemd-template change.
+No live installer or acceptance run, provider, home/config, unit or host access.
+
+## Choices
+
+1. Recommended: resolve the configured dataRoot as the stack user, preserve
+   hardening, check the final pathname's metadata and use SO_PEERCRED on a
+   connection to identify its listener. This supports custom roots within the
+   unit's existing writable home and matches196's kernel-peer approach.
+2. Assume <home>/.mosaic-dev and inspect a pathname in /proc/net/unix. This
+   misses a custom config and is not a reliable final-path ownership check:
+   196 binds a temporary name and renames it. A socket's filesystem inode also
+   must not be confused with its kernel socket inode. Do not use this option.
+3. Add a TCP relay, relax hardening or give acceptance a configurable probe
+   executable. All widen the surface or trust inputs and are outside this row.
+
+There is no second bus principal verifier. The acceptance probe observes an
+OS endpoint; it grants no capability and sends no HTTP or bus request.
+
+## Installer arguments and preflight
+
+Factory keeps required --port (1..1023) and --business; tester remains optional
+for the installer. --tester-socket is a single marker, takes no value and keeps
+its position in the rendered flags. The existing duplicate-flag check applies.
+A following stray value is an unknown flag. --tester-port always refuses in
+serve arguments, for both profiles, before unit writes or systemctl actions:
+
+    case2-unit: case2-unit.sh retires tester TCP; use --tester-socket
+
+Library rejects --tester-socket with an explicit library-profile refusal. Its
+other flags, proof-file checks and install behavior are unchanged. No legacy
+conversion or fallback to TCP is introduced in this installer.
+
+When the factory socket marker is present, a small inline metadata query runs
+the selected copy's config loader under the target uid with sudo -u USER -H,
+env -i, explicit HOME and the same pinned-node-first PATH used by the unit.
+Root never imports user-writable copy code as root. It invokes the previously
+validated --node path after dropping uid, with the copy module path as a
+separate argument. This resolves the default instance just as the rendered
+unit does; no MOSAIC_CONFIG or named-instance override is inherited.
+
+The query returns only dataRoot and whether that copy's Console carries the
+MOSAIC_TESTER_SOCKET_V1 marker. It prints no config values, credentials or child
+diagnostics. Bound it to five seconds and 4096 output bytes; reject errors,
+extra output/keys, malformed results, missing config and unsupported targets.
+No root process opens a config or credential under the user's home. Existing
+root metadata checks remain root metadata checks. Both script headers explain
+the new, explicitly unprivileged config query.
+
+Before any unit writes, validate the socket location:
+
+- dataRoot is an absolute normalized plain path, below the declared home,
+  with no symlink in its existing path. Never expand the unit's writable scope.
+- Neither home nor dataRoot is under /home, /root, /run/user, /tmp or /var/tmp.
+  These roots conflict with the existing ProtectHome/PrivateTmp contract.
+- <dataRoot>/console/tester.sock is at most 107 ASCII bytes, matching196.
+- A missing console parent is allowed; runtime creates it. An existing parent
+  must be a real directory, not a symlink, owned by the target uid with no
+  group/other permissions. A foreign owner, non-directory or unsafe mode refuses.
+- Do not create/chmod the parent or inspect/delete an existing tester entry in
+  the installer. A running Console may own it during a re-pin. Runtime196 owns
+  binding and cleanup. Reinstall still does not restart running units.
+
+The dataRoot query and all refusal families get fake-only tests. A failed
+preflight leaves both units and the systemctl log unchanged.
+
+## How the rendered unit reaches the socket
+
+The unit still has User/Group for the stack account, ProtectSystem=strict,
+ReadWritePaths=<home>, ProtectHome=yes and PrivateTmp=yes, in the same order.
+Its ExecStart contains --tester-socket, with no pathname argument. The Console
+loads dataRoot and derives console/tester.sock itself. Case1/2's /srv/mosaic
+home is outside ProtectHome's protected hierarchies; the allowed dataRoot is
+inside the existing writable home, and the socket is outside private /tmp.
+No extra capability or writable directory is added. Systemd's documented
+namespace rules motivate the location refusals, rather than a hardening change.
+[systemd.exec](https://www.freedesktop.org/software/systemd/man/latest/systemd.exec.html)
+
+A mutable same-uid config can change between preflight and start. The unit's
+writable boundary is still home; runtime's own config/socket checks still
+refuse unsafe state. This row does not promise an immutable same-uid config.
+The host window must verify the rendered unit actually starts under its
+namespace; scratch tests inspect its directives, not a real systemd namespace.
+
+## Acceptance arguments and endpoint observation
+
+The saved args must contain one --tester-socket and the numeric --port.
+Reject a missing/duplicate marker, a marker with an old numeric value, and
+--tester-port with the same migration wording naming case1-accept.sh. Preserve
+all existing pre-- argument validation and the default-instance contract.
+Malformed saved inputs still refuse with exit2 before functional checks.
+
+Acceptance resolves the actual configured tester dataRoot with the same
+unprivileged, bounded query. It does not silently use the default path. An
+unreadable/invalid config or a root outside the unit's allowed home refuses
+before the functional talk. The old DATA_ROOT used by F11 remains unchanged;
+generalizing that separate Discord check is outside this row.
+
+P10 independently requires the Console's systemd MainPID to be positive and
+stable, and its four /proc uid fields to be the stack uid. Check the private
+parent's type, owner and mode, and the final entry's non-symlink socket type,
+owner and exact 0600 mode. Snapshot parent/socket dev+ino and metadata before
+and after the peer probe; a replacement or MainPID change fails observation.
+The port floor must still be numeric and above the privileged main Console
+port, retaining that existing part of the observation.
+
+The bounded probe runs as the stack user with an empty inherited environment,
+the fixed system /usr/bin/python3 resolved to a root-owned ELF, safe root-owned
+ancestors, and -I -S. This is the system Python dependency already required by
+196; never use PATH python, a home shim or a configurable helper. Unsafe/missing
+Python is a failed P10 observation, not a fallback. Resolve/check the system
+entry and target using metadata and the ELF header; do not run copy Python code
+as root. Test seams emulate these root facts and the system executable.
+
+The probe opens AF_UNIX/SOCK_STREAM, uses a one-second connect timeout, reads
+SO_PEERCRED and closes. An outer three-second process-group bound applies. It
+returns only pid/uid/gid, with exact structure, bounded output and numeric
+validation. pid must equal MainPID and uid the stack uid; gid is validated but
+not an identity grant. No application bytes, cookies, credentials or proof
+envelope are sent. Linux supplies the peer credentials for the connected
+stream, so the check does not depend on the temporary bind pathname.
+[unix(7), SO_PEERCRED](https://man7.org/linux/man-pages/man7/unix.7.html)
+
+This is a snapshot. Hostile same-uid processes can alter same-uid state or
+interfere with the unprivileged probe. Root, ptrace and later pathname changes
+are not defeated here. The probe does not prove another uid is denied; that
+remains a host-window observation, not a fake test claim.
+
+## P8 and P10 outcome lines
+
+P8 must change with removal of TESTER_PORT. It checks the main Console port is
+loopback-only and held only by MainPID, and that nothing listens on TCP7331 or
+the retired TCP7333. Socket ownership belongs to P10. Its healthy line is:
+
+    P8 lan-listeners closed <port> is on 127.0.0.1 only by MainPID <pid>; no TCP listener on 7331 or 7333; tester uses <socket>
+
+An unexpected listener, missing main listener or wrong owner produces P8
+lan-listeners unnamed with the observed listener summaries, as today.
+
+Do not reuse accepted mos-1101 for a new Unix-socket claim: that ruling named a
+TCP-port condition. Proposed safe default pending any new Mos classification:
+
+    P10 tester-socket-squat unnamed boundary=observed path=<socket> parent=0700 owner=<uid> socket=0600 peer_pid=<pid> peer_uid=<uid> floor=<floor> port=<port>; hostile same-uid substitution remains
+
+Any missing/unsafe metadata, wrong peer, unsafe interpreter, malformed/timeout
+probe, floor miss or changed snapshot produces one P10 line instead:
+
+    P10 tester-socket-squat unnamed boundary=failed reason=<bounded-code> path=<socket> MainPID=<pid>; hostile same-uid substitution remains
+
+Healthy observation does not mark the same-uid squat path closed or invent an
+accepted ruling. P checks still never change exit status. Tests pin the reason
+and observed/failed distinction, so validation cannot disappear behind an
+always-unnamed mark. Sage/Mos may supply a new classification at design review;
+it must be explicit before changing this proposed mark. No Jason question is
+needed merely to retain unnamed evidence.
+
+## Evidence and planned checks
+
+Keep the existing scratch fixtures, fake account database/systemctl/curl/ss/
+sudo/stat and fake interpreter. Add copy config/marker fixtures and probe
+metadata under those same roots. No test connects to a live socket or runs the
+real host scripts without their existing seams. Fixture fakes verify the
+unprivileged command argv; no test claims a real uid drop or namespace.
+The fake system interpreter executes the actual probe payload against a fake
+Python socket API, checking AF_UNIX/SOCK_STREAM, timeout, connect, getsockopt
+arguments and returned peer bytes. This catches errors in the inline probe
+without opening an OS listener. The metadata query is tested with nonzero
+status plus valid-looking output as well as malformed output, so removing its
+status refusal cannot hide behind a later parse error.
+

+| T9 failed P10 | Parent/socket faults, wrong PID/uid, malformed/timeout probe, unsafe Python, bad floor and changed snapshot each give failed reason |
+| T10 preserved behavior | Functional checks, their exit semantics, library behavior and all other P paths retained |

+Planned checks to kill, one target change at a time in isolated snapshots:
+
+| IDs | Removed requirement |
+|---|---|
+| M1-M3 | Installer TCP refusal, library socket refusal, duplicate socket refusal |
+| M4-M5 | Config-query failure refusal, unsupported-target refusal |
+| M6-M8 | Home containment, protected/private path refusal,107-byte limit |
+| M9-M11 | Existing parent type/symlink, uid, mode checks |
+| M12-M15 | Acceptance TCP refusal, required marker, duplicate/stray marker rejection, config-query refusal |
+| M16 | P8 retired TCP7333 check |
+| M17-M18 | P10 parent and final socket metadata checks |
+| M19-M21 | Peer PID, peer uid, malformed/timeout probe refusal |
+| M22-M23 | Safe fixed system interpreter, stable metadata/MainPID snapshot |
+| M24-M25 | Target-uid invocation in installer and acceptance metadata/probe paths |
+| M26 | Privileged main-port floor observation |
+| M27 | Probe returns its own PID rather than the connected peer's credentials |
+
+Before execution, give every definition one unique source target and a named
+killer test. Preserve raw logs, base times, syntax preflight and byte-identical
+SHA/Git restoration. A timeout counts only under Sage's explicit rules and
+must kill the process group. Refusal variants in T1-T9 must not be merely
+assertions of a generic nonzero exit.
+
+## Static inventory and gate
+
+After implementation, enumerate every --tester-port hit in scripts/packages
+in BUILD.md and a machine-readable file. The only permitted hits are the brief's
+deliberate legacy producers/parsers/tests and this row's explicit refusals and
+negative fixtures. Inspect arguments and generated units, not just filenames.
+Readmes must describe retirement rather than produce old argv. No modification
+to webui-service, stack-release, instance, their tests/fixture, case1-hostcheck
+or tester-cli negative calls is planned. Stop and ask Sage if one is needed.
+
+Then request Sage's slot. Under that grant, run CLI whole, WebUI whole, every
+shell test suite whole and all named checks above. Use an isolated candidate,
+plain linked node_modules, a short gXXX TMPDIR under /mnt/storage/scratch/tmp,
+busy &&, pipefail and tee. Single/pattern runs need the slot too, per sage-2142.
+No harness/helper/log argument may match the busy detector pattern, per
+mos-1205. Two failures end the window; report any stop to Sage/Mos before a
+retry. Return the slot with script-summed counts/timings and a leftover sweep.
+
+Design approval precedes code. The manifest, immutable candidate hashes,
+static inventory and gate evidence go to Duckworth before Sage's landing.
+Queue moves use the helper, with a coordinated queue-write gap. Sage posts the
+jarvis review request after the in-review move. BUILD-LOG/session history stays
+append-only; Sage continues session registration. No host deployment is part
+of row253 acceptance.

+# Row253 implementation plan
+
+Goal: migrate the two host scripts to the private tester socket without widening
+their unit or root execution boundary. Spec: DESIGN.md, approved by
+duckworth-0100 with C1-C5; Sage2173 approves the two design decisions.
+Execution: Gander implements inline; Duckworth reviews the final manifest.
+
+Constraints: four product/test files only; no edits to the brief's legacy paths;
+no tests before Sage's slot, including patterns. Static inspection precedes the
+full slot request. All tests use the existing scratch/fake seams.
+
+- [x] Task1: write factory/acceptance socket fixture and refusal tests first.
+  Add config/marker and isolated probe fakes; assert target-uid argv, strict
+  parsing, all C1 path variants and C4 descendant cleanup. Preserve baseline
+  functional/P checks while changing only the intended socket outcomes.
+- [x] Task2: implement the marker parsing, bounded target-uid query, strict bash
+  parser, component/no-follow location checks and parent preflight in installer.
+  Preserve hardening and update its header, including sudo dependency.
+- [x] Task3: migrate saved args and P8/P10. Implement metadata snapshots and the
+  bounded isolated system-Python peer observation; keep P10 unnamed with explicit
+  observed/failed evidence and same-uid residual. Update header and remove the
+  obsolete accepted-mos-1101 mark. Keep F11 default DATA_ROOT behavior unchanged.
+- [x] Task4: static audit every remaining retired-port occurrence; prepare unique
+  M1-M33 including C1 middle-symlink/sibling-prefix, C2 character, C3 parser and C4
+  process-group checks. Request the slot once the candidate static check passes.
+- [ ] Task5: on Sage's grant, execute RED cases against isolated prior behavior,
+  GREEN candidate checks, CLI/WebUI whole, all shell files and the checks. Record
+  counts/times, clean restoration, leak sweep and exact frozen manifest. Return
+  the slot, then queue review only in a coordinated write gap.
+
+Review focus: prefix collisions; intermediate symlinks; forged output lines;
+nonzero query with valid-looking JSON; ignored signals/leftover descendants;
+kernel versus filesystem inode; wrong Console peer or metadata replacement.
+
+Ruling: tests are written first, but their execution waits for the user-required
+slot after static preparation. No pre-slot test or passing claim; RED/GREEN
+execution is an explicit part of the granted verification, not claimed in advance.

+Current static source audit after the two approved fixture fixes. Each remaining hit and its reason follows.
+

+# Row253 granted gate
+
+Do not launch until Sage's CLEAR names this scope. No tests have run yet.
+Use this worktree, the frozen five blobs in CANDIDATE-SHAS.json and the plain
+node_modules link. No canonical-checkout node or queue writes during the slot.
+
+Set TMPDIR with `mktemp -d /mnt/storage/scratch/tmp/gXXX`, export it and use
+`set -o pipefail`. Record the grant and the exact date before launch. Use logs
+under this packet's `run1/`, with the outer log named `controller.log`.
+Neither helper nor wrapper argv may match the busy detector's patterns.
+
+Sequence, stopping to inspect every result:
+
+1. `window.py --stage focused`: isolated prior installer and acceptance RED
+   examples, restoring bytes/status in finally, then both focused test files
+   whole GREEN. Expected RED is recorded separately from gate failures.
+2. `driver.py`: 33 unique single-target changes, named base cases and killer
+   runs. Each base must pass in under 30 seconds. bash -n is the only invalid
+   classification. Runtime errors kill a change; unexpected timeouts stop for
+   Sage/Mos. Every run records time, code, raw tee log and byte/status restore.
+3. `window.py --stage whole`: cli whole, webui whole and the ten shell files
+   whole. No omitted tests, patterns or partial scripts in this phase.
+4. Sum counts and seconds from raw logs by script. Sweep process cwd/ancestry
+   for this worktree's node, tee, query and probe descendants. Report existing
+   processes separately. Return the slot immediately, then prepare review.
+
+Every driver invocation needs `--grant <Sage-id> --out <record-directory>`.
+Before each actual test, driver.run checks Sage's busy guard and launches only
+on CLEAR. It invokes a bash pipefail/tee pipeline through launch.py, which
+loads the structured command after the guard. No command text is embedded in
+wrapper argv. All execution is in a new process group and timed out groups
+are killed and waited for. Query-owned groups are independently bounded by
+product code; the orphan fixture also cleans its own recorded PID.
+
+Two unexpected failures end the window. These drivers stop at the first
+unexpected base, focused or whole-phase failure for inspection, without
+automatically rerunning it. Any timeout is a stop. Send a stop to Sage/Mos
+and do not turn an ungranted retry into a new run.

+
+## Open
+
+- **Inherited Discord engine test intermittency during #1512 review.** Frozen
+  serialized run recorded a tool-turn engine assertion failure and then timed
+  out at 120s. A later full TAP run with a 15s test deadline passed 351/351.
+  Rocko isolated the busy/settled-event test race and missing failure cleanup;
+  Darkwing independently reproduced the event-split assertion. Rocko also reported
+  a timeout-log test race and a separate engine followUp-after-timeout defect.
+  No live incident established. Row21 owner orch-01 notified; no Discord source
+  takeover. Not assumed identical to earlier concurrent hangs.
+  Integration held pending owner disposition; logs and scope in
+  `agents/darkwing/work/relaunch-activity/r1-review.md`. (2026-09-15)
+  Outcome 2026-09-26: 1685deb4 fixed the busy/settled race and the engine no
+  longer sends a follow-up (held prompts). A re-run of the frozen candidate
+  against 21e3e908 passed the serial acceptance command 397/397 three times.
+  Two engine failures remain when tests run concurrently, and they reproduce on
+  clean HEAD without the #1512 files, so they are #1509's (entry below). Sage
+  ruled that #1512 integrates on the serial evidence; it landed in af4203ca.
+  Record: `agents/darkwing/work/relaunch-activity/rerun-2026-09-26.md`.
+
+
+
+- **Registration has no "set by" field.** `mosaic seat task` records the
+  task and `updatedAt` but not who set it, so a human session and the
+  orchestrator look the same on the board. One-line record change; rides
+  with the orchestrator assignment piece. (2026-09-12, #1504)
+- **Usage-limit notice was missed.** Jason reports Rocko exhausted usage without
+  Jason seeing the notice, and is now available again. Investigate where the
+  notice appeared and what operator notification is missing as part of Claude
+  console integration. User-reported, not independently reproduced; no root
+  cause established. Keep outside #1512's relaunch-display scope. (2026-09-15)
+- **Claude Code seats register but get no board row.** Rocko has no Pi
+  session log, and rows come only from Pi logs. Needs a second row source
+  or a Claude-side log reader. (2026-09-12, darkwing's #1504 report)
+  2026-09-15 #1511 live-test preflight reconfirmed no Rocko row: expected
+  `.pi/state/rocko/sessions` discovery directory absent. Its existing repo
+  registration names dead PID 185602, while the verified native lock owner is
+  3707667. No registration repair, discovery expansion or relaunch performed;
+  test write refused before mutation. Evidence:
+  `agents/darkwing/work/task-attribution/backend-live-verification.json`.
+- **Fleet seats (`~/.mosaic`) stay on the old launchers.** No registration,
+  no board reply, no `seat task`. Moving them is the stress test and comes
+  after the WebUI and fleet launch work. (Jason, 2026-09-12)
+- **Comms skill has no rule for senders without a pane.** The board trailer
+  covers it today; if another pane-less sender appears, put the rule in
+  `skills/ms-communications` instead of a second trailer. (2026-09-12, #1505)
+- **Board: multiple sessions per seat, stopping seats, auth beyond
+  loopback.** Out of scope for the MVP by the plan; listed so they are not
+  forgotten. (plan page, Boundaries)
+- **`MOSAIC-STACK-D-001` is Answered, not Completed.** Mark `--completed` in
+  jarvis-brain once Jason says the board answers "who is waiting on me".
+  (2026-09-12)
+- **Uncommitted working tree.** `AGENTS.md` autonomy section,
+  `agents/README.md` Sage row, Dewey's `work/wui` docs and evidence,
+  `docs/plans/reviews/2026-09-08..10_*`, `skills/ms-{arena,blast-radius,
+  board,executive-update,git-operations,technical-writing}`. Jason's edits
+  from before 2026-09-12; they ride along in the next commit that touches
+  them unless staged on purpose. (2026-09-12)
+- **Fleet debt (orch-01, `~/.mosaic`):** `sweep-commit.sh` deny-list regex
+  skips `launch.env`; needs the fix plus a regression test. (2026-09-12)
+- **Parked, not cancelled:** Dewey D05 dashboard mockup work beyond design 3,
+  registry increment 3 (headless identity-env leak), new seat directories.
+  (plan page, 2026-09-12 parking note)
+
+- **Gitea helper response-file hardening.** Predictable `/tmp/gitea-api-response.$$`
+  has no explicit 0600 mode; use `mktemp` with cleanup in a separately reviewed
+  pass. Credential validation and later reread also have a race window. Other
+  non-blocking ledger review notes remain in
+  `reviews/2026-09-12_ledger-verdict.md`. No change beyond the reviewed GET
+  cleanup fix in this piece. Filbert, LEDGER-1506-R1, 2026-09-12, #1506.
+
+- **One shared checkout for every seat and the coordinator.** Any `git add`
+  of a shared file (CURRENT.md, SESSIONS.md, the plan page) commits another
+  seat's in-progress edit under the wrong commit; it happened at f80404f5
+  (dewey's CURRENT.md status note went in with the piece 5 brief, harmless
+  but unowned). Fix candidates: per-seat worktrees, or shared files edited
+  only by the seat named in CURRENT.md. (2026-09-12)
+
+- **Console mockup fields absent from the board API.** Controller, generation,
+  config fingerprint, turn count, goal/report and activity stream are omitted.
+  Workspace paths are shown as board data, not invented registered workspace
+  nodes. Launch, observe, stop, full transcript navigation, command palette and
+  other screens are absent. Existing palette/appearance switches remain on the
+  single page. Revisit only with a new brief. (2026-09-13 UTC, #1507)
+
+- **Board send can turn into a Pi slash command.** `tools/tmux`
+  `send-message.sh` pastes onto whatever is already in Pi's composer without
+  clearing it. On Jason's 2026-09-26 20:10:57Z send, a leftover "/" landed in
+  front of the agent-send header. Pi read it as plain text that time, but the
+  same path could run a board reply as a slash command. Belongs to CHAT-03I/B3.
+  No tools/tmux change until that piece. Found by Dewey in the CHAT-02 brief
+  evidence. (2026-09-26, #1507)
+
+- **Discord wedge restarts have no cumulative stop.** Since 6b R2, a wedged
+  pi ends the connector with exit 1, and the unit restarts it. With
+  turnTimeoutSeconds 600, one cycle takes at least 645 s, longer than the
+  600 s StartLimit window. So a pi that wedges on every prompt restarts once
+  per prompt and never hits the limit. It only happens when someone sends a
+  message, and that person gets an error reply. Sage accepted it for now. The
+  fix is a separate policy (a wedge count kept across restarts). (2026-09-26,
+  #1509, Rocko 6b R2 review)
+- **Connector does not journal the source it started from.** The unit runs
+  from the live checkout, so an automatic restart loads whatever Discord
+  source is in the tree, even uncommitted source. Rocko recommends a startup
+  journal line with HEAD, the dirty state of `packages/discord` and a digest
+  of the runtime files. Until then the rule is that unreviewed Discord source
+  stays uncommitted in the tree only as long as a review needs it.
+  (2026-09-26, #1509)
+- **Index-export suite runs leave Docker networks behind.** Each export
+  directory becomes a compose project, and its `<dir>_default` network
+  stays after the run. On 2026-09-26 the host ran out of address pools. The
+  task and release suites then failed 31 and 3 tests with "all predefined
+  address pools have been fully subnetted". Sage removed its own five stale
+  networks. The dw-* ones are still there. Fix: the export recipe, or the
+  suites, removes the project network on exit. (2026-09-26)
+  2026-09-27: it happened again on the Piece D candidate (task 31 and
+  release 3 failures). Sage removed 12 leftover export networks from
+  other seats, each checked for zero attached containers first, and both
+  suites then passed. Still open.
+
+- **Ledger T3 read: snapshot isolation has no test.** `readT3` runs every
+  query in one read transaction, but no test proves a write landing during
+  the read stays invisible. Filbert's note 4 on the Gate F build (e47ec6da).
+  Notes 1 to 3 go to Darkwing's follow-up. (2026-09-26, #1506)
+- **A T3 sender role with spaces counts as human.** The SetSpark lead's
+  reply to Sage (21:41:24Z) used the role "main content-engine agent". The
+  6a rule requires a one-word role, so the ledger counts that message as
+  human in Sage's row. Gate F reads only Filbert's row, so it is not
+  affected. Filbert found it through the live diagnostic (14 went to 15).
+  Sage asked the SetSpark lead to use a one-word role. The rule stays as
+  it is. (2026-09-26, #1506)
+
+- **Queue tests: the cold-start failure came back (reopened).** Row 33
+  closed this as not reproduced in 20 idle cold runs. On 2026-10-04 Sage's
+  index export of the row 33 candidate ran the nine suites, then
+  `node --test packages/queue/tests/`, and got 147 passed, 1 failed. Sage's
+  recipe threw the output away, so again nobody knows which test failed.
+  Ten more runs all passed 148/148: three reruns in the same export, four
+  under parallel suite load, and three fresh exports run straight after
+  `test-queue.sh`. It needs a first run on a fresh tree after a full
+  suite pass, and even then it's rare. Darkwing's n2 on row 33 (the cold
+  runs were idle) was right. Next time: Sage's export recipe keeps the
+  node test output in a file, so the first failure has a name. Then fix it
+  as its own row. (2026-10-04, #1508)
+- **Queue: `add --issue N` also sets closes to N.** Follow-up rows under
+  an umbrella issue, like rows 31 and 33 under #1508, would close the issue
+  when they finish. Sage narrowed both by hand (revs 36 and 43). Either
+  `add` takes `--closes` or the lead checks closes on every add. Not
+  urgent while Sage adds the rows. (2026-10-04, #1508)
+
+- **Ledger metric call can orphan curl.** The metric call in
+  `packages/ledger/src/ledger.mjs` still relies on execFileSync's
+  timeout, which kills the helper but can leave curl running. E's queue
+  calls already use `timeout -s KILL`; the metric call should match.
+  (2026-09-27, #1508)
+- **Ledger: a missing `timeout` command reads as a Gitea failure.** With
+  no `timeout` on PATH the queue issue calls report "credential or Gitea
+  request failure". Optional test and clearer message. Filbert, E r2.
+  (2026-09-27, #1508)
+- **`review record` doesn't check which issue the verdict comment is on.**
+  Row 5 round 1's request (26671) and Filbert's verdict (26683) are on
+  #1507. Darkwing's verdict 26681 went to #1508, and `review record`
+  accepted it, because only `review resolve` reads the comment back
+  (`checkComment` in `packages/queue/src/review.mjs`). The receipt
+  points at a real comment on the wrong issue. Sage posted a pointer on
+  #1507 (comment 26685). Fix: have `record` check the comment's issue and author the way
+  `resolve` does, or refuse a comment id it can't verify. Found by
+  Filbert. (2026-10-04, #1508)
+- **Host seats launch Pi with `--approve`.** A future `.pi/SYSTEM.md` or
+  `.pi/settings.json` in the checkout would load in every host seat. This
+  is latent, since neither file exists today. Fix in
+  `scripts/agent-host-dev.sh`: pass `--no-approve` and an explicit system
+  prompt. Filbert, meta-harness survey section 8.4. (2026-10-04)
+- **Workers can read provider keys.** The worker container passes
+  `ZAI_API_KEY` and `ANTHROPIC_API_KEY` in the environment, which Pi's
+  `bash` inherits, and Pi's `read` can open the mounted `auth.json`.
+  Slice 1 role tokens stay in the broker (lead decision 47). The workers'
+  own exposure needs a separate piece. Filbert, survey section 8.6.
+  (2026-10-04)
+- **CHAT-03 I1 round 2 follow-ups, for the I3 brief.** Neither reviewer
+  held any of these as blocking (Darkwing comment 26690, Filbert comment
+  26694 on #1507). Four of the five are closed by slice 1 S5 (see Done);
+  this one stays open.
+  - No test proves that the processes are listed only after the cgroup
+    is frozen. The code waits for `frozen 1` in `cgroup.events`, and
+    both Filbert and Dewey confirmed it by reading it. Mutants r2-B5b and
+    C4 survive. Proposed: a test-only hold after `members`, or a FUSE or
+    privileged fixture. Filbert F1.
+  (2026-10-04, #1507)
+- **CHAT-03 `engine.envKeys` accepts founder credential names.**
+  `CREDENTIAL_NAME` in `packages/conversation/src/pi-pin.mjs` matches any
+  `*_API_KEY` or `*_TOKEN`, including `GITEA_TOKEN` and `GH_TOKEN`, which
+  the S6 runner refuses as founder credentials (REQ-CRED-2). Nothing
+  builds a Controller outside the tests yet. Whoever wires the entry point
+  narrows the pattern to provider names or checks the founder list.
+  Filbert N2 on #1522. (2026-10-10)
+- **`test-task.sh` makes a live Pi call without the Docker guard.** The
+  "user recall" block near line 478 runs `run-task.sh` with no
+  availability check, so a run with Docker unavailable fails "user recall
+  run succeeds" and "recalled user name" (26 pass, 2 fail). The other
+  live groups skip. Rocko hit it during the S2 suites. Wrap the block in
+  the same guard as the other live groups, so a seat without provider
+  access gets clean skips. (2026-10-04, #1519)
+- **`node --test <dir>/` fails on Node 24.** Node 24 reads a directory
+  argument as a module, so every package's test command in that form
+  fails there, while Node 26 accepts it. The glob form
+  (`node --test 'packages/x/tests/*.test.mjs'`) works on both. Package
+  READMEs, `docs/TOOLS.md` and Sage's suite recipe should use the glob
+  form wherever Node 24 is a target. Darkwing, S1 packet. (2026-10-04,
+  #1518)
+- **`stack-upgrade.sh` doesn't check `$REPO`.** Nothing confirms the
+  source checkout is root-owned or that its tree is clean before the
+  upgrade builds from it. Filbert N2 on row 233 (29922, #1735).
+  (2026-10-21)
+- **`stack-upgrade.sh` has no signal handling between A2 and A5.** A HUP,
+  INT or TERM in that stretch leaves the run failed closed, but recovery
+  is by hand. A trap that writes the stop point and the recovery step to
+  the log would make it a sheet step. Filbert N3 on row 233 (29922,
+  #1735). (2026-10-21)
+- **`checkCreative` doesn't refuse `credentials`.** Row 213's
+  `checkCreative` (packages/business/src/role.mjs:143 at 2d2ad2760)
+  limits a creative role's tools, authority and messaging, but a role
+  file that gave companion or research a credential would still load.
+  The business file could then map a credential to that instance
+  (business.mjs:157). Nobody has traced whether a mapped credential
+  reaches the run's environment. The decision paths stay closed (M6),
+  but a creative role with `web` holding a live token is a wider channel
+  than design 4 means. The fix: refuse any `credentials` in
+  `checkCreative`, with a role.test.mjs case. It goes after row 213
+  lands, as a follow-up row or in the next row that edits role.mjs.
+  Webby N1 on row 213 r3 (REVIEW-r3.md, 3ab3c010b), mos-1160.
+  (2026-10-21)
+- **The boot host check orders only one business's bus.**
+  `mosaic-hostcheck.service` (row 240) has
+  `[email protected]`. `case2-unit.sh` enables the
+  bus as `mosaic-bus@<business>.service`, so on a host whose business id
+  isn't `mosaic-stack` nothing orders the two. The bus can start before
+  the boot stop runs, and after a boot-time drift role sessions can use
+  bwrap until it does. The fix: `After=mosaic-hostcheck.service` in
+  `packages/cli/systemd/mosaic-bus.service.in`, which orders every
+  instance and does nothing where the unit isn't installed. It goes in
+  before the first install whose business id isn't `mosaic-stack`.
+  Filbert N1 on row 240 (29945, #1746). (2026-10-21)
+- **The run sheet writes the apt hook before the first `--check`.**
+  Section 4 installs `80mosaic-hostcheck`, then runs
+  `hostcheck.sh --check`. If that check fails, the next package run
+  closes bwrap before anyone has read the failure. It fails closed, but
+  it surprises an installer. The fix: run `--check` first, or say what a
+  failure at that step means. Doc-only, for the next row that edits
+  `docs/guides/host-run-sheet.md`. Filbert N2 on row 240 (29945, #1746).
+  Filbert's N3, that a closed bwrap appends to `DRIFT` on every later
+  apt run and boot, is by design; ops-01's STATE read should expect the
+  repeats. (2026-10-21)
+- **The sso-config first-step hint has no business.** When the target
+  copy has no `console.sso`, `stack-release.sh` (`:938`) refuses with
+  "activate $TO without --sso first, then ... activate $TO --sso". The
+  usage line is `activate ID BUSINESS` (`:47`), so pasting either command
+  as printed gives a usage error, not the first step. It fails safe,
+  since the usage error changes nothing. The fix: add `$BUSINESS`
+  (set at `:2138`) to both commands, and the business (`acme`)
+  to the three expected strings in `stack-release.test.mjs`
+  (`:1538`, `:1689`, `:1691`). For a later row that edits
+  `stack-release.sh`. Webby N1 on row 238 r1 (REVIEW-r1.md, 433a95292,
+  #1744). (2026-10-21)
+- **Lane image prep inspects a base that BuildKit never tagged.**
+  (N7 of the row 197 proof.) After the Compose build,
+  `scripts/testing/lane-image.mjs:41` (`prepareImage`) runs
+  `docker image inspect node:24-bookworm-slim` to put the base digest
+  in the receipt. BuildKit resolves the base from the registry
+  without tagging it in the local store, so on a host without the tag
+  the inspect throws "No such image" after a good build. That
+  happened in Sage's proof try 1 (2026-10-21 09:03Z, run cf48efccf083).
+  The throw fails closed: the run's terminal record is unclean, both
+  lanes quarantine, and `gate-lane.sh recover` clears them. Pulling the
+  base first fixes it, and the receipt digest then matches what the
+  build used (91acba91 both ways). The fix: before the build, inspect
+  the base and refuse with a named reason if it's missing, or pull it.
+  After the build, refuse if the base digest changed. Add a test with a
+  fake Docker that has no base tag. Kept out of row 197 r6 by Sage
+  (sage-1883). Mos asked for this record in mos-1162. (2026-10-21)
+- **Case 1 acceptance script: root parses with the node it's checking, and the header says less than root does.**
+  (Duckworth N1-N3 on the row 195 manifest, REVIEW-m1 6afcee2a5.)
+  N1: F9 runs `$ROOT$NODE` as root (`scripts/case1-accept.sh:298`)
+  before F10 checks that `--node` is the `/opt/mosaic-stack/node-<pin>`
+  path (:303-304). On a host installed as designed, `case2-unit.sh:128-133`
+  refused a non-root-owned `--node` and the args file is root's, so no
+  escalation path exists today. Run F9's parse through `AS_USER`, or
+  apply F10's path check first. N2: the header (:10) and the TOOLS.md
+  entry say root only reads, but root also runs `curl` (F2), `sudo -l`
+  (P1, P3), the jarvis probe (P9), `hostcheck.sh --check` and
+  `systemctl`. Doc-only. N3: F6's prefix match (:261) accepts a
+  `--claude` with `..` after `claude-<pin>/`. That claude runs only as
+  `mosaic`, and F10 uses equality. Darkwing has a follow-up on
+  `darkwing/row195-n1` 1e3c4767c, not yet run; it gets its own row now
+  that 195 has landed (b65014647), Duckworth reviews. (2026-10-21)
+- **Morgana's row 213 mutation set: the B3 pattern no longer matches `bundle.mjs`.**
+  (Webby N3 on row 221 round 1, REVIEW-r1 a0a00630e.) Row 221's
+  candidate changes `packages/harness/src/bundle.mjs`, and the B3
+  anchor at Morgana's 213 `mutants.py:48` stops matching on that
+  base. This matters only if someone reruns that set. Fix the anchor
+  in that tooling before any rerun, and check that a stale anchor
+  refuses instead of skipping the mutant (sage-1941). (2026-10-21)
+- **Grant executor test X5 starts a `sleep 30` that can outlive its test.**
+  (Webby N1 on row 248 r1, webby-0080; deferred by Duckworth in the row
+  249 review, REVIEW-r1 28174fe08, #1751 comment 30070.) The test at
+  `packages/bus/tests/grant-executor.test.mjs:989` (:934 before row
+  249) runs `sleep 30` on the sshd side, where an abort doesn't reach it. Fix it with a stub
+  that exits once its test dir is gone, as row 248 did for the hold
+  stubs, or with a shorter sleep. This binds the next row that touches
+  that test file. Until then, a lane cleanup that runs after this file
+  waits 30 s before it calls a lone `sleep 30` a leak. The row 197
+  lanes scan only at lane end, about 15 minutes after pkg-bus, so they
+  can't see it (mos-1169). (2026-10-21)
+
+- **Row 66 live checks: the unslop notice on a live managed session, both harnesses.**
+  (mos-1186, Vikunja #454.) Row 66's gate asked for one landing session per
+  harness with a prompt that draws a known tell. Mos changed that gate. The
+  Claude Code session ran before landing on a scratch root from the
+  candidate tree (run r4ab24630d323, landed 2c38325ec). Pi ran launch only there (run r1dd94171bede):
+  this host has no credential pi reads until P19 #383 settles. Two live
+  checks remain. Claude Code: in the first re-pin whose tree includes row 66,
+  backup first (Q173). Pi: one full session with a tell after #383. Each
+  attaches the operator note on the RESULT, the next-turn correction and the
+  `unslop.jsonl` counts. (2026-10-21)
+
+- **Console tester listener: `testerNoSignIn` is a dead parameter.**
+  (Duckworth N2 on the row 196 manifest, REVIEW-m1; carried as C1 in
+  REVIEW-m2 cdbf7b64e, #1694 comment 30156.) Row 196 landed 7247d80c7
+  with the parameter and its comment still at `serve.mjs:472-475` and
+  passed from `webui/src/cli.mjs:109` and `sso.test.mjs:392`. Nothing
+  in `serve.mjs` reads it after the destructure. Remove it, or wire it
+  with a test. This binds the next row that touches
+  `packages/webui/src/serve.mjs`. (2026-10-21)
+- **Console library routes: the tester listener and `library.sync`.**
+  (Duckworth N5 on row 196 round 2, REVIEW-m2 cdbf7b64e.) At 7247d80c7
+  `startServer` (`serve.mjs:475`) takes none of `libraryFile`,
+  `libraryStatus` or `librarySync`, so the callbacks `cli.mjs` passes
+  do nothing yet. The row that adds the Console library routes decides
+  whether the tester listener gets `library.sync`. Duckworth's view is
+  that it shouldn't, because sync is a human write. (2026-10-21)
+- **Console library routes: four library codes still map to 502.**
+  (Dewey N2 on the row 254 manifest, #1759 comment 30173.) Row 254
+  gave six library codes a STATUS entry in `packages/webui/src/bus.mjs`.
+  `library-mapping-invalid`, `library-remote-invalid`,
+  `library-state-invalid` and `library-git` still fall through
+  `busStatus` to 502. The row that adds the Console library routes
+  decides their statuses and gives its `humanCall` for `library.sync`
+  a timeout over 130 seconds. (2026-10-21)
+- **T27 sweep test leaves two `sleep 60` children running.**
+  (Darkwing row 251 slot, darkwing-0113 and darkwing-0117; Dewey on
+  r2, comment 30168.) The sweep test spawns two detached shells,
+  `planted` at `host-run.test.mjs:528` and `decoy` at `:536`, each
+  running `sleep 60; :` with the run dir as `$0`. `sweepRunDir` kills
+  the planted shell by pid (`host-run.mjs:238`), and `t.after` kills
+  only the decoy shell. Neither kill reaches the `sleep` child, so each
+  one lives for up to 60 s after the test and trips any busy check that
+  follows. The fix is to kill the process group in both `t.after`
+  hooks: `process.kill(-pid, 'SIGKILL')`. Each shell is spawned
+  detached, so it leads its own group. `exec sleep 60` doesn't work.
+  The sweep matches the run dir in `/proc/<pid>/cmdline`
+  (`host-run.mjs:236`), and exec drops the `$0` that carries it, so the
+  planted process would survive and the "planted process killed" assert
+  would fail. This binds the next row that touches
+  `packages/bus/tests/host-run.test.mjs`. (2026-10-21)
+- **Real-model suite cases run outside the gate.** Row 244 moved
+  `test-task.sh` fork recall (M11) and user recall (M16) behind
+  `MOSAIC_LIVE_PROVIDER=1`, and `test-release.sh` activations to the mock
+  adapter. Before any re-pin whose tree changes `packages/harness` or the
+  session fork code (`scripts/mosaic-task.mjs` session and
+  `sessionForkFrom` handling, the pi adapter), an operator runs
+  `MOSAIC_LIVE_PROVIDER=1 bash scripts/test-task.sh` with the real pi
+  credential and a real `release.sh activate`, and records both results on
+  the re-pin row. Morgana's wording (row 244 BUILD.md), Webby N2 on row 244
+  r1 (#1757). (2026-10-21)
+
+## Queue
+
+Moved to `docs/plans/QUEUE.md` on 2026-09-13. This file holds only gaps.
+
+## Done
+
+- Ledger (piece 3, #1506): shipped cd0aa5fb, Gate D written 2026-09-12 (18.9 human messages per closed issue).
+- Relaunched seat shows the old last message (darkwing, Step 3 log, 2026-09-12): closed by #1512 relaunch activity, af4203ca. Filbert authored it; Darkwing and Dewey reviewed. The live board restart and Gate F remain separate.
+- Sage launcher hook uncommitted (2026-09-12): closed by the agents/sage launch files commit, Dewey review R1 revise, R2 approve (`agents/dewey/work/sage-launch-review-2026-09-26.md`), launcher test now covers sage.
+- Ledger counts T3 agent messages as human (2026-09-26, #1506): fixed in ef0020ad (Darkwing 6a, Filbert reviewed). `messageKind` now counts a T3 header as agent and the control-board sender as board. It changes no current count, because no source the ledger reads has a T3 header yet. That waits for the T3 thread source (Gate F).
+- Control board checked the bind address but not Host or Origin (2026-09-26, #1507, found by Dewey): closed by the board guard commit. `foreignRequest` refuses a non-loopback Host, a wrong port, userinfo or a path in Host, and any foreign Origin on every route. Dewey authored it, and Rocko approved it (`agents/rocko/work/board-guard-review-2026-09-26.md`, 5a12f08e). Rocko's one low finding: URL normalization accepts a root slash, empty userinfo and an empty query in Host, so the notes' wording overstates what the raw-syntax check refuses. No bypass was found.
+- Discord engine: leaked fake pi and the timeout gap in `busy` (2026-09-26, #1509): fixed in 3edb15eb (Darkwing 6b R2, Rocko approved, review ed5510a0). Tests stop the engine in `finally`. A turn pi never started now stops pi with exit 1 instead of guessing, and the unit restarts it. Known limit: see the open entry on wedge restarts.
+- Combined concurrent test hangs (2026-09-14, #1509): closed on evidence from 3edb15eb. At default concurrency the union passed 406/406 three times on the R2 snapshot and 408/408 on the commit's index, where clean HEAD had hung four runs out of four. The inherited-intermittency entry from 2026-09-15 stays open until a later run shows it is the same cause.
+- A nested `node --test` passes even when its tests fail (2026-09-26, #1508): closed. Queue A1 (34a72af9) clears NODE_TEST_CONTEXT on its own path. N13 fixes `test-foundation.sh` and `test-discord.sh`, each with a check that fails the suite if the clearing is lost. Darkwing wrote it (n13.patch 00868b2f) and Filbert approved it (e464be6c). Sage's grep on 2026-09-27 finds no other nested `node --test`: in scripts, only the two suites, `test-queue.sh` and `queue-commit.sh`, and in JS, only the queue test that covers the fix.
+- SetSpark service accepted any string as a decision approver (2026-09-26, #1509): closed. Fixed in shared-signals cc74d92 (Rocko approved R2, lead decision 24). The operations seat (T3 12fe8cda) deployed it to VM 1022 at 00:23Z on 2026-09-27. The running `service.py` hash matches cc74d92, and `/healthz` returns 200 inside the network and through the public tunnel. The read-only README survey found one row breaking the rule (DEC-009, Proposed, version 1), one open request that isn't ready (DEC-009's), and no Accepted decision with more than 16 approvers. No rows changed. DEC-009 stays as stored (lead decisions 21 and 28). The service now refuses approvals on it, so nothing can go wrong silently. Side effect: `up -d` also recreated caddy, about 20 s of edge downtime for all hosts. That is for the shared-signals deploy procedure to fix, not Mosaic.
+- Queue suite failed its live checks outside the canonical checkout
+  (2026-09-27, #1508): closed by Piece D, f539466f. `test-queue.sh` now
+  skips `verify` and `render --check` with a printed reason when the
+  toplevel isn't the recorded `canonicalRoot`. An index export passed
+  27/0, and the canonical checkout 29/0.
+- Queue: an owner listed as a reviewer blocked the row (2026-09-27,
+  #1508): closed by row 31, bb2fa970. `add`, `set reviewers` and `assign`
+  now refuse the owner as a reviewer with exit 2 and write nothing. Rocko
+  built it in the Gate G run, and Filbert approved round 1 (#1508 comment
+  26629, 8 of 8 mutants caught).
+- Queue follow-ups from rows 12, 13 and 31 (2026-10-04, #1508): closed by
+  row 33, 6fb50cc0. Filbert built it, and Darkwing approved round 1
+  (#1508 comment 26651).
+  - `genesis` refuses a map row whose owner is one of its reviewers (exit
+    2, nothing written). The check is on the map, not in replay, so a log
+    from before the rule still loads.
+  - The `assign` refusal now reads "can't assign row N to SEAT: SEAT is
+    one of its reviewers".
+  - `queue-commit.sh` compares HEAD with H before each canary and again if
+    the clean run fails. A moved HEAD exits 2 with "HEAD moved since H was
+    recorded"; the guard message is kept for a real guard failure.
+  - Every time and date the validator accepts must format back to itself,
+    so month 13, day 32, 2026-02-30, 2027-02-29 and 24:00 are refused.
+    The live log at rev 45 still replays.
+  - The cold-start failure (2026-09-27): not reproduced in 20 cold runs.
+    Each ran `node --test packages/queue/tests/` in a fresh tree, 10
+    shared clones and 10 exports, one after another. All 20 passed
+    148/148 (2960 of 2960). The 300 ms deadline test is unchanged. Counts:
+    `agents/filbert/work/queue-33/cold-runs.txt`.
+- CHAT-03 I1 round 2 follow-ups (2026-10-04, #1507): four of five closed
+  by slice 1 S5 (row 40, #1522; Dewey authored, Darkwing and Filbert
+  reviewing). The commit is named in the row's review record when it
+  lands.
+  - Engine command and `preArgs`: `engine` takes only `extraArgs`, `cwd`
+    and `envKeys`. The controller always launches the pinned Pi and
+    checks that at construction and at bind. The fake engine comes in
+    through a symbol key that JSON config can't carry (N24b).
+  - Engine environment: an explicit list (`ENGINE_ENV` in `pi-pin.mjs`)
+    plus `*_API_KEY` and `*_TOKEN` names from `engine.envKeys`. Nothing
+    else is inherited. `HOME` passes, so Pi reads `~/.pi/agent` unless
+    `PI_CODING_AGENT_DIR` is set (Darkwing F3).
+  - `escalating` is cleared when the force-stop fence throws (Darkwing F2,
+    races.test.mjs).
+  - Takeover then Enter in one chunk: input after Ctrl-T or Ctrl-O waits
+    for that action, in the same chunk or a later one, and also while an
+    earlier action is still pending, so it is judged as if typed one key
+    at a time (Filbert F2; Darkwing and Filbert T1 on #1522;
+    flows.test.mjs).
+  The frozen-cgroup test (Filbert F1) stays open above.
+- Gate runs mount the host's pi auth file (Webby N4 on the row 197 proof
+  driver, 059577886): closed by row 244 (#1757), landing e69260a3c. The
+  suites and the lane's `cleanEnv` export a 0600 fixture `PI_AUTH_FILE`,
+  `guardDocker` refuses a Compose run without one, and
+  `packages/cli/tests/gate-lane-auth.test.mjs` proves no gate step mounts
+  the host default. The real-model cases this moved off the gate are open
+  above.
+
+## Row253 F5: legacy Case AS_USER supervision
+
+Tracked as row 276, Gitea #1781 (sage-2331), owner Gander, reviewer Duckworth, after row253.
+Brief: docs/plans/2026-10-22_case-sudo-legacy-followup.md, “Brief: supervised legacy AS_USER calls”.
+
+case1-accept.sh's legacy timeout330 around AS_USER talk and its AS_USER precheck, Claude version, PM launches and Node version diagnostics predate the new socket metadata/probe helpers. sudo's pty monitor can move them to a separate session; the old outer timeout does not prove their descendants are killed. The C4 repair in row253 covers only its new config query and peer probe. These legacy paths need the reviewed supervisor or a header explicitly explaining why each remains unsupervised. The follow-up must preserve the 300-second talk/reply contract, concurrent F5 scan, diagnostics and secret-output refusals, with fake-only session-hop tests and Sage's slot. No host or live unit change is authorized.

+# C4 repair for the short static pass
+
+Prepared under duckworth-0111 and sage-2325/2331. No tests, syntax execution, probe, real sudo or host experiment ran on this repair. No passing claim applies to these new product bytes. DESIGN.md and the approved DESIGN-C4.md remain unchanged. The original frozen snapshots remain unchanged.
+
+REPAIR.diff compares the repaired scripts against their original frozen source, and tests/docs against 968db0bcd. The *.repair.txt files are non-executable exact snapshots of all seven pending source/test/doc paths. REPAIR-SHAS.json pins them. The live source/test paths remain uncommitted until the gate permits the product commit.
+
+## Conditions mapped to the diff
+
+C1: fixed setsid without -f/-w; confirm the direct child's kernel SID equals its PID. M38 drops setsid; the named row253 C4 signals query killer must fail the exact numeric PID/SID equality assertion on the first query-pids line, in each kind and both sudo modes, without a timeout. A blocking child can still reach inner-timeout without setsid, so the refusal reason alone does not prove session creation (mos-1298).
+
+C2: exact inner/outer/output-limit refusals in both fake modes, query 5/7 s and probe 2/4 s. Outer cases require at least the outer duration and less than outer + 2 s. Root discards the valid-looking stdout of a stalled supervisor. A trusted notice plus status 137 identifies the outer timer.
+
+C3: read complete stat files, strip through the last closing parenthesis followed by space, skip vanished entries, refuse on other errors. The setpgid member has newline, closing parenthesis and space in comm. M36 kills only the leader group and must fail that case. The existing 250 ms cleanup budget and 50 x 10 ms post-return test polling remain.
+
+C4: DEFERRED.md names row 276 / #1781 and the brief from sage-2331. It is an intended manifest path. UPSTREAM-PATHS.json records the requested comparison. Current upstream DEFERRED.md was preserved before our entry.
+
+C5: the test compares both inline payloads byte for byte; M39 adds a comment to only one. Both payloads were prepared from supervisor-source.txt.
+
+N1: the fake reads its mode with the Bash file-read builtin form. N2: fixture cleanup rechecks SID before each kill, including members discovered by an owned-session scan. N3: exec mode cannot safely scan the runner's session, so it checks exact PIDs and says so; hop mode checks all members of self-led recorded sessions. N4: the fake still makes no synthetic HUP on its own death. N5: polling remains bounded at 500 ms. N6: the packet must be published before the manifest round.

+
+On Sage CLEAR after static approval: both touched files whole, M1-M39 with passing focused bases and byte-identical restoration, CLI whole, WebUI whole and the ten shell files. Previous completed results are historical only because product blobs changed. Use a gXXXXXX TMPDIR under /mnt/storage/scratch/tmp, pipefail and tee, a busy check before every launch, and log/wrapper names that do not match the busy detector. Stop and report according to the new grant.

++## Row253 F5: legacy Case AS_USER supervision
++
++Tracked as row 276, Gitea #1781 (sage-2331), owner Gander, reviewer Duckworth, after row253.
++Brief: docs/plans/2026-10-22_case-sudo-legacy-followup.md, “Brief: supervised legacy AS_USER calls”.
++
++case1-accept.sh's legacy timeout330 around AS_USER talk and its AS_USER precheck, Claude version, PM launches and Node version diagnostics predate the new socket metadata/probe helpers. sudo's pty monitor can move them to a separate session; the old outer timeout does not prove their descendants are killed. The C4 repair in row253 covers only its new config query and peer probe. These legacy paths need the reviewed supervisor or a header explicitly explaining why each remains unsupervised. The follow-up must preserve the 300-second talk/reply contract, concurrent F5 scan, diagnostics and secret-output refusals, with fake-only session-hop tests and Sage's slot. No host or live unit change is authorized.

+#
+# Root runs it on the Case 1 host after the install window, from a root-owned checkout. It reads the
+# user, home, copy, node, claude, main port and tester socket marker from the args file, which must pass stack-upgrade.sh's
+# rules and be a factory file for --business. Every command that runs the stack's code runs as
+# `sudo -u USER -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin` from /. Root itself reads ss,
+# /proc, the account database and file metadata, and runs these: systemctl show and is-enabled (F1,
+# P11), curl on the Console's loopback healthz (F2), sudo -l (P1, P3), sudo -u jarvis bwrap --version
+# and hostcheck.sh --check (P9), and node to parse managed-settings.json (F9). F9 runs node only when
+# --node is the pinned path and it and every directory above it are root's with no group or other
+# write. The script changes nothing on the host but the message F3 sends and its reply, and it never
+# opens claude-session.env. A bounded config/target query imports the copy only as the stack
+# user, with sudo and an empty environment. Root parses its two facts in bash. P10 uses the
+# fixed system Python, also as the stack user, for a read-only SO_PEERCRED observation.
+# The config/probe supervisor is fixed root-validated system Bash plus setsid
+# and sleep, after the uid drop: query inner/outer 5/7 s, probe 2/4 s. Root
+# independently bounds its sudo wait. Legacy AS_USER talk and diagnostics below
+# retain their old behavior and are NOT covered by this supervisor (F5 follow-up).
+#
+# One line per check, `<id> <path> <mark> <evidence>`, then `count <mark> N` for each mark and a
+# result line. F checks are `pass` or `FAIL`. P checks are `closed`, `accepted <ruling>` or
+# `unnamed`, which means no Q182, Q183 or Mos ruling names the path; each unnamed line goes to Mos.
+#
+# Exit 0 when every F check passes, 1 when one fails, 2 on usage or a refusal (a bad args file, or
+# --root misused). A P check never changes the exit.
+#
+# Test seam, for packages/cli/tests/case1-accept.test.mjs only. Root takes none:
+#   --root DIR   prefixes the args file, /etc, /proc, the stack's home, the host check and node, and

+# Root runs it on the Case 1 host after the install window, from a root-owned checkout. It reads the
+# user, home, copy, node, claude, main port and tester socket marker from the args file, which must pass stack-upgrade.sh's
+# rules and be a factory file for --business. Every command that runs the stack's code runs as
+# `sudo -u USER -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin` from /. Root itself reads ss,
+# /proc, the account database and file metadata, and runs these: systemctl show and is-enabled (F1,
+# P11), curl on the Console's loopback healthz (F2), sudo -l (P1, P3), sudo -u jarvis bwrap --version
+# and hostcheck.sh --check (P9), and node to parse managed-settings.json (F9). F9 runs node only when
+# --node is the pinned path and it and every directory above it are root's with no group or other
+# write. The script changes nothing on the host but the message F3 sends and its reply, and it never
+# opens claude-session.env. A bounded config/target query imports the copy only as the stack
+# user, with sudo and an empty environment. Root parses its two facts in bash. P10 uses the
+# fixed system Python, also as the stack user, for a read-only SO_PEERCRED observation.
+#
+# One line per check, `<id> <path> <mark> <evidence>`, then `count <mark> N` for each mark and a
+# result line. F checks are `pass` or `FAIL`. P checks are `closed`, `accepted <ruling>` or
+# `unnamed`, which means no Q182, Q183 or Mos ruling names the path; each unnamed line goes to Mos.
+#
+# Exit 0 when every F check passes, 1 when one fails, 2 on usage or a refusal (a bad args file, or
+# --root misused). A P check never changes the exit.
+#
+# Test seam, for packages/cli/tests/case1-accept.test.mjs only. Root takes none:
+#   --root DIR   prefixes the args file, /etc, /proc, the stack's home, the host check and node, and

+# Case 2 row C2-13a (design 9.3, 10 step 2c): render and install the two
+# system units a hub runs as, [email protected] (enabled as
+# mosaic-bus@<business>.service) and mosaic-webui.service, from the existing
+# templates, which it doesn't change.
+#
+#   case2-unit.sh --user NAME --home DIR --business ID --copy ID --node PATH
+#                 [--profile factory|library] [--pm] [--claude PATH]
+#                 -- SERVE FLAGS
+#
+# Root runs it from a root-owned checkout of the reviewed commit outside
+# <home>, never from the release, because <user> can write the release. It
+# writes both units under /etc/systemd/system as root:root 0644, runs
+# `systemctl daemon-reload`, enables both, then starts the bus and then the
+# Console (Q189). Both come back after a boot on their own. It never links
+# a unit file into place. Root only stats files under <home> and reads bounded
+# stdout from a config/target query run as the stack user through sudo. Root
+# never imports copy code. This adds sudo and GNU timeout to the installer
+# dependencies. The inner query supervisor runs after the uid drop: 5 s inside,
+# 7 s on root's wait. Fixed system Bash, setsid, sleep, timeout and head are
+# resolved and root-validated. Only the config query uses this supervisor.
+# It renders the default instance only.
+#
+# The library profile takes exactly these serve flags, each once:
+#   --port N (1..1023)  --business ID (the unit's)  --public-host NAME
+#   --auth-header HEADER  --allow-user ID  --send
+#   --proof-header NAME  --proof-file PATH
+# The factory profile takes --port N (1..1023) and --business ID, and an
+# optional bare --tester-socket marker. Retired tester TCP refuses. Only factory takes
+# --pm and --claude.
+#
+# On a re-install the installed units must equal the render in everything
+# but the copy id, and both must name one copy, so a re-pin or rollback
+# re-renders the pair together. A unit that was already running stays on its
+# old copy, since `systemctl start` leaves it alone; the script says so and
+# that the bus and Console must restart together, and restarts nothing.
+#
+# Test seams, for packages/cli/tests/case2-unit.test.mjs only:
+#   CASE2_UNIT_DIR        the unit directory, default /etc/systemd/system;

+
+## Open
+
+- **Inherited Discord engine test intermittency during #1512 review.** Frozen
+  serialized run recorded a tool-turn engine assertion failure and then timed
+  out at 120s. A later full TAP run with a 15s test deadline passed 351/351.
+  Rocko isolated the busy/settled-event test race and missing failure cleanup;
+  Darkwing independently reproduced the event-split assertion. Rocko also reported
+  a timeout-log test race and a separate engine followUp-after-timeout defect.
+  No live incident established. Row21 owner orch-01 notified; no Discord source
+  takeover. Not assumed identical to earlier concurrent hangs.
+  Integration held pending owner disposition; logs and scope in
+  `agents/darkwing/work/relaunch-activity/r1-review.md`. (2026-09-15)
+  Outcome 2026-09-26: 1685deb4 fixed the busy/settled race and the engine no
+  longer sends a follow-up (held prompts). A re-run of the frozen candidate
+  against 21e3e908 passed the serial acceptance command 397/397 three times.
+  Two engine failures remain when tests run concurrently, and they reproduce on
+  clean HEAD without the #1512 files, so they are #1509's (entry below). Sage
+  ruled that #1512 integrates on the serial evidence; it landed in af4203ca.
+  Record: `agents/darkwing/work/relaunch-activity/rerun-2026-09-26.md`.
+
+
+
+- **Registration has no "set by" field.** `mosaic seat task` records the
+  task and `updatedAt` but not who set it, so a human session and the
+  orchestrator look the same on the board. One-line record change; rides
+  with the orchestrator assignment piece. (2026-09-12, #1504)
+- **Usage-limit notice was missed.** Jason reports Rocko exhausted usage without
+  Jason seeing the notice, and is now available again. Investigate where the
+  notice appeared and what operator notification is missing as part of Claude
+  console integration. User-reported, not independently reproduced; no root
+  cause established. Keep outside #1512's relaunch-display scope. (2026-09-15)
+- **Claude Code seats register but get no board row.** Rocko has no Pi
+  session log, and rows come only from Pi logs. Needs a second row source
+  or a Claude-side log reader. (2026-09-12, darkwing's #1504 report)
+  2026-09-15 #1511 live-test preflight reconfirmed no Rocko row: expected
+  `.pi/state/rocko/sessions` discovery directory absent. Its existing repo
+  registration names dead PID 185602, while the verified native lock owner is
+  3707667. No registration repair, discovery expansion or relaunch performed;
+  test write refused before mutation. Evidence:
+  `agents/darkwing/work/task-attribution/backend-live-verification.json`.
+- **Fleet seats (`~/.mosaic`) stay on the old launchers.** No registration,
+  no board reply, no `seat task`. Moving them is the stress test and comes
+  after the WebUI and fleet launch work. (Jason, 2026-09-12)
+- **Comms skill has no rule for senders without a pane.** The board trailer
+  covers it today; if another pane-less sender appears, put the rule in
+  `skills/ms-communications` instead of a second trailer. (2026-09-12, #1505)
+- **Board: multiple sessions per seat, stopping seats, auth beyond
+  loopback.** Out of scope for the MVP by the plan; listed so they are not
+  forgotten. (plan page, Boundaries)
+- **`MOSAIC-STACK-D-001` is Answered, not Completed.** Mark `--completed` in
+  jarvis-brain once Jason says the board answers "who is waiting on me".
+  (2026-09-12)
+- **Uncommitted working tree.** `AGENTS.md` autonomy section,
+  `agents/README.md` Sage row, Dewey's `work/wui` docs and evidence,
+  `docs/plans/reviews/2026-09-08..10_*`, `skills/ms-{arena,blast-radius,
+  board,executive-update,git-operations,technical-writing}`. Jason's edits
+  from before 2026-09-12; they ride along in the next commit that touches
+  them unless staged on purpose. (2026-09-12)
+- **Fleet debt (orch-01, `~/.mosaic`):** `sweep-commit.sh` deny-list regex
+  skips `launch.env`; needs the fix plus a regression test. (2026-09-12)
+- **Parked, not cancelled:** Dewey D05 dashboard mockup work beyond design 3,
+  registry increment 3 (headless identity-env leak), new seat directories.
+  (plan page, 2026-09-12 parking note)
+
+- **Gitea helper response-file hardening.** Predictable `/tmp/gitea-api-response.$$`
+  has no explicit 0600 mode; use `mktemp` with cleanup in a separately reviewed
+  pass. Credential validation and later reread also have a race window. Other
+  non-blocking ledger review notes remain in
+  `reviews/2026-09-12_ledger-verdict.md`. No change beyond the reviewed GET
+  cleanup fix in this piece. Filbert, LEDGER-1506-R1, 2026-09-12, #1506.
+
+- **One shared checkout for every seat and the coordinator.** Any `git add`
+  of a shared file (CURRENT.md, SESSIONS.md, the plan page) commits another
+  seat's in-progress edit under the wrong commit; it happened at f80404f5
+  (dewey's CURRENT.md status note went in with the piece 5 brief, harmless
+  but unowned). Fix candidates: per-seat worktrees, or shared files edited
+  only by the seat named in CURRENT.md. (2026-09-12)
+
+- **Console mockup fields absent from the board API.** Controller, generation,
+  config fingerprint, turn count, goal/report and activity stream are omitted.
+  Workspace paths are shown as board data, not invented registered workspace
+  nodes. Launch, observe, stop, full transcript navigation, command palette and
+  other screens are absent. Existing palette/appearance switches remain on the
+  single page. Revisit only with a new brief. (2026-09-13 UTC, #1507)
+
+- **Board send can turn into a Pi slash command.** `tools/tmux`
+  `send-message.sh` pastes onto whatever is already in Pi's composer without
+  clearing it. On Jason's 2026-09-26 20:10:57Z send, a leftover "/" landed in
+  front of the agent-send header. Pi read it as plain text that time, but the
+  same path could run a board reply as a slash command. Belongs to CHAT-03I/B3.
+  No tools/tmux change until that piece. Found by Dewey in the CHAT-02 brief
+  evidence. (2026-09-26, #1507)
+
+- **Discord wedge restarts have no cumulative stop.** Since 6b R2, a wedged
+  pi ends the connector with exit 1, and the unit restarts it. With
+  turnTimeoutSeconds 600, one cycle takes at least 645 s, longer than the
+  600 s StartLimit window. So a pi that wedges on every prompt restarts once
+  per prompt and never hits the limit. It only happens when someone sends a
+  message, and that person gets an error reply. Sage accepted it for now. The
+  fix is a separate policy (a wedge count kept across restarts). (2026-09-26,
+  #1509, Rocko 6b R2 review)
+- **Connector does not journal the source it started from.** The unit runs
+  from the live checkout, so an automatic restart loads whatever Discord
+  source is in the tree, even uncommitted source. Rocko recommends a startup
+  journal line with HEAD, the dirty state of `packages/discord` and a digest
+  of the runtime files. Until then the rule is that unreviewed Discord source
+  stays uncommitted in the tree only as long as a review needs it.
+  (2026-09-26, #1509)
+- **Index-export suite runs leave Docker networks behind.** Each export
+  directory becomes a compose project, and its `<dir>_default` network
+  stays after the run. On 2026-09-26 the host ran out of address pools. The
+  task and release suites then failed 31 and 3 tests with "all predefined
+  address pools have been fully subnetted". Sage removed its own five stale
+  networks. The dw-* ones are still there. Fix: the export recipe, or the
+  suites, removes the project network on exit. (2026-09-26)
+  2026-09-27: it happened again on the Piece D candidate (task 31 and
+  release 3 failures). Sage removed 12 leftover export networks from
+  other seats, each checked for zero attached containers first, and both
+  suites then passed. Still open.
+
+- **Ledger T3 read: snapshot isolation has no test.** `readT3` runs every
+  query in one read transaction, but no test proves a write landing during
+  the read stays invisible. Filbert's note 4 on the Gate F build (e47ec6da).
+  Notes 1 to 3 go to Darkwing's follow-up. (2026-09-26, #1506)
+- **A T3 sender role with spaces counts as human.** The SetSpark lead's
+  reply to Sage (21:41:24Z) used the role "main content-engine agent". The
+  6a rule requires a one-word role, so the ledger counts that message as
+  human in Sage's row. Gate F reads only Filbert's row, so it is not
+  affected. Filbert found it through the live diagnostic (14 went to 15).
+  Sage asked the SetSpark lead to use a one-word role. The rule stays as
+  it is. (2026-09-26, #1506)
+
+- **Queue tests: the cold-start failure came back (reopened).** Row 33
+  closed this as not reproduced in 20 idle cold runs. On 2026-10-04 Sage's
+  index export of the row 33 candidate ran the nine suites, then
+  `node --test packages/queue/tests/`, and got 147 passed, 1 failed. Sage's
+  recipe threw the output away, so again nobody knows which test failed.
+  Ten more runs all passed 148/148: three reruns in the same export, four
+  under parallel suite load, and three fresh exports run straight after
+  `test-queue.sh`. It needs a first run on a fresh tree after a full
+  suite pass, and even then it's rare. Darkwing's n2 on row 33 (the cold
+  runs were idle) was right. Next time: Sage's export recipe keeps the
+  node test output in a file, so the first failure has a name. Then fix it
+  as its own row. (2026-10-04, #1508)
+- **Queue: `add --issue N` also sets closes to N.** Follow-up rows under
+  an umbrella issue, like rows 31 and 33 under #1508, would close the issue
+  when they finish. Sage narrowed both by hand (revs 36 and 43). Either
+  `add` takes `--closes` or the lead checks closes on every add. Not
+  urgent while Sage adds the rows. (2026-10-04, #1508)
+
+- **Ledger metric call can orphan curl.** The metric call in
+  `packages/ledger/src/ledger.mjs` still relies on execFileSync's
+  timeout, which kills the helper but can leave curl running. E's queue
+  calls already use `timeout -s KILL`; the metric call should match.
+  (2026-09-27, #1508)
+- **Ledger: a missing `timeout` command reads as a Gitea failure.** With
+  no `timeout` on PATH the queue issue calls report "credential or Gitea
+  request failure". Optional test and clearer message. Filbert, E r2.
+  (2026-09-27, #1508)
+- **`review record` doesn't check which issue the verdict comment is on.**
+  Row 5 round 1's request (26671) and Filbert's verdict (26683) are on
+  #1507. Darkwing's verdict 26681 went to #1508, and `review record`
+  accepted it, because only `review resolve` reads the comment back
+  (`checkComment` in `packages/queue/src/review.mjs`). The receipt
+  points at a real comment on the wrong issue. Sage posted a pointer on
+  #1507 (comment 26685). Fix: have `record` check the comment's issue and author the way
+  `resolve` does, or refuse a comment id it can't verify. Found by
+  Filbert. (2026-10-04, #1508)
+- **Host seats launch Pi with `--approve`.** A future `.pi/SYSTEM.md` or
+  `.pi/settings.json` in the checkout would load in every host seat. This
+  is latent, since neither file exists today. Fix in
+  `scripts/agent-host-dev.sh`: pass `--no-approve` and an explicit system
+  prompt. Filbert, meta-harness survey section 8.4. (2026-10-04)
+- **Workers can read provider keys.** The worker container passes
+  `ZAI_API_KEY` and `ANTHROPIC_API_KEY` in the environment, which Pi's
+  `bash` inherits, and Pi's `read` can open the mounted `auth.json`.
+  Slice 1 role tokens stay in the broker (lead decision 47). The workers'
+  own exposure needs a separate piece. Filbert, survey section 8.6.
+  (2026-10-04)
+- **CHAT-03 I1 round 2 follow-ups, for the I3 brief.** Neither reviewer
+  held any of these as blocking (Darkwing comment 26690, Filbert comment
+  26694 on #1507). Four of the five are closed by slice 1 S5 (see Done);
+  this one stays open.
+  - No test proves that the processes are listed only after the cgroup
+    is frozen. The code waits for `frozen 1` in `cgroup.events`, and
+    both Filbert and Dewey confirmed it by reading it. Mutants r2-B5b and
+    C4 survive. Proposed: a test-only hold after `members`, or a FUSE or
+    privileged fixture. Filbert F1.
+  (2026-10-04, #1507)
+- **CHAT-03 `engine.envKeys` accepts founder credential names.**
+  `CREDENTIAL_NAME` in `packages/conversation/src/pi-pin.mjs` matches any
+  `*_API_KEY` or `*_TOKEN`, including `GITEA_TOKEN` and `GH_TOKEN`, which
+  the S6 runner refuses as founder credentials (REQ-CRED-2). Nothing
+  builds a Controller outside the tests yet. Whoever wires the entry point
+  narrows the pattern to provider names or checks the founder list.
+  Filbert N2 on #1522. (2026-10-10)
+- **`test-task.sh` makes a live Pi call without the Docker guard.** The
+  "user recall" block near line 478 runs `run-task.sh` with no
+  availability check, so a run with Docker unavailable fails "user recall
+  run succeeds" and "recalled user name" (26 pass, 2 fail). The other
+  live groups skip. Rocko hit it during the S2 suites. Wrap the block in
+  the same guard as the other live groups, so a seat without provider
+  access gets clean skips. (2026-10-04, #1519)
+- **`node --test <dir>/` fails on Node 24.** Node 24 reads a directory
+  argument as a module, so every package's test command in that form
+  fails there, while Node 26 accepts it. The glob form
+  (`node --test 'packages/x/tests/*.test.mjs'`) works on both. Package
+  READMEs, `docs/TOOLS.md` and Sage's suite recipe should use the glob
+  form wherever Node 24 is a target. Darkwing, S1 packet. (2026-10-04,
+  #1518)
+- **`stack-upgrade.sh` doesn't check `$REPO`.** Nothing confirms the
+  source checkout is root-owned or that its tree is clean before the
+  upgrade builds from it. Filbert N2 on row 233 (29922, #1735).
+  (2026-10-21)
+- **`stack-upgrade.sh` has no signal handling between A2 and A5.** A HUP,
+  INT or TERM in that stretch leaves the run failed closed, but recovery
+  is by hand. A trap that writes the stop point and the recovery step to
+  the log would make it a sheet step. Filbert N3 on row 233 (29922,
+  #1735). (2026-10-21)
+- **`checkCreative` doesn't refuse `credentials`.** Row 213's
+  `checkCreative` (packages/business/src/role.mjs:143 at 2d2ad2760)
+  limits a creative role's tools, authority and messaging, but a role
+  file that gave companion or research a credential would still load.
+  The business file could then map a credential to that instance
+  (business.mjs:157). Nobody has traced whether a mapped credential
+  reaches the run's environment. The decision paths stay closed (M6),
+  but a creative role with `web` holding a live token is a wider channel
+  than design 4 means. The fix: refuse any `credentials` in
+  `checkCreative`, with a role.test.mjs case. It goes after row 213
+  lands, as a follow-up row or in the next row that edits role.mjs.
+  Webby N1 on row 213 r3 (REVIEW-r3.md, 3ab3c010b), mos-1160.
+  (2026-10-21)
+- **The boot host check orders only one business's bus.**
+  `mosaic-hostcheck.service` (row 240) has
+  `[email protected]`. `case2-unit.sh` enables the
+  bus as `mosaic-bus@<business>.service`, so on a host whose business id
+  isn't `mosaic-stack` nothing orders the two. The bus can start before
+  the boot stop runs, and after a boot-time drift role sessions can use
+  bwrap until it does. The fix: `After=mosaic-hostcheck.service` in
+  `packages/cli/systemd/mosaic-bus.service.in`, which orders every
+  instance and does nothing where the unit isn't installed. It goes in
+  before the first install whose business id isn't `mosaic-stack`.
+  Filbert N1 on row 240 (29945, #1746). (2026-10-21)
+- **The run sheet writes the apt hook before the first `--check`.**
+  Section 4 installs `80mosaic-hostcheck`, then runs
+  `hostcheck.sh --check`. If that check fails, the next package run
+  closes bwrap before anyone has read the failure. It fails closed, but
+  it surprises an installer. The fix: run `--check` first, or say what a
+  failure at that step means. Doc-only, for the next row that edits
+  `docs/guides/host-run-sheet.md`. Filbert N2 on row 240 (29945, #1746).
+  Filbert's N3, that a closed bwrap appends to `DRIFT` on every later
+  apt run and boot, is by design; ops-01's STATE read should expect the
+  repeats. (2026-10-21)
+- **The sso-config first-step hint has no business.** When the target
+  copy has no `console.sso`, `stack-release.sh` (`:938`) refuses with
+  "activate $TO without --sso first, then ... activate $TO --sso". The
+  usage line is `activate ID BUSINESS` (`:47`), so pasting either command
+  as printed gives a usage error, not the first step. It fails safe,
+  since the usage error changes nothing. The fix: add `$BUSINESS`
+  (set at `:2138`) to both commands, and the business (`acme`)
+  to the three expected strings in `stack-release.test.mjs`
+  (`:1538`, `:1689`, `:1691`). For a later row that edits
+  `stack-release.sh`. Webby N1 on row 238 r1 (REVIEW-r1.md, 433a95292,
+  #1744). (2026-10-21)
+- **Lane image prep inspects a base that BuildKit never tagged.**
+  (N7 of the row 197 proof.) After the Compose build,
+  `scripts/testing/lane-image.mjs:41` (`prepareImage`) runs
+  `docker image inspect node:24-bookworm-slim` to put the base digest
+  in the receipt. BuildKit resolves the base from the registry
+  without tagging it in the local store, so on a host without the tag
+  the inspect throws "No such image" after a good build. That
+  happened in Sage's proof try 1 (2026-10-21 09:03Z, run cf48efccf083).
+  The throw fails closed: the run's terminal record is unclean, both
+  lanes quarantine, and `gate-lane.sh recover` clears them. Pulling the
+  base first fixes it, and the receipt digest then matches what the
+  build used (91acba91 both ways). The fix: before the build, inspect
+  the base and refuse with a named reason if it's missing, or pull it.
+  After the build, refuse if the base digest changed. Add a test with a
+  fake Docker that has no base tag. Kept out of row 197 r6 by Sage
+  (sage-1883). Mos asked for this record in mos-1162. (2026-10-21)
+- **Case 1 acceptance script: root parses with the node it's checking, and the header says less than root does.**
+  (Duckworth N1-N3 on the row 195 manifest, REVIEW-m1 6afcee2a5.)
+  N1: F9 runs `$ROOT$NODE` as root (`scripts/case1-accept.sh:298`)
+  before F10 checks that `--node` is the `/opt/mosaic-stack/node-<pin>`
+  path (:303-304). On a host installed as designed, `case2-unit.sh:128-133`
+  refused a non-root-owned `--node` and the args file is root's, so no
+  escalation path exists today. Run F9's parse through `AS_USER`, or
+  apply F10's path check first. N2: the header (:10) and the TOOLS.md
+  entry say root only reads, but root also runs `curl` (F2), `sudo -l`
+  (P1, P3), the jarvis probe (P9), `hostcheck.sh --check` and
+  `systemctl`. Doc-only. N3: F6's prefix match (:261) accepts a
+  `--claude` with `..` after `claude-<pin>/`. That claude runs only as
+  `mosaic`, and F10 uses equality. Darkwing has a follow-up on
+  `darkwing/row195-n1` 1e3c4767c, not yet run; it gets its own row now
+  that 195 has landed (b65014647), Duckworth reviews. (2026-10-21)
+- **Morgana's row 213 mutation set: the B3 pattern no longer matches `bundle.mjs`.**
+  (Webby N3 on row 221 round 1, REVIEW-r1 a0a00630e.) Row 221's
+  candidate changes `packages/harness/src/bundle.mjs`, and the B3
+  anchor at Morgana's 213 `mutants.py:48` stops matching on that
+  base. This matters only if someone reruns that set. Fix the anchor
+  in that tooling before any rerun, and check that a stale anchor
+  refuses instead of skipping the mutant (sage-1941). (2026-10-21)
+- **Grant executor test X5 starts a `sleep 30` that can outlive its test.**
+  (Webby N1 on row 248 r1, webby-0080; deferred by Duckworth in the row
+  249 review, REVIEW-r1 28174fe08, #1751 comment 30070.) The test at
+  `packages/bus/tests/grant-executor.test.mjs:989` (:934 before row
+  249) runs `sleep 30` on the sshd side, where an abort doesn't reach it. Fix it with a stub
+  that exits once its test dir is gone, as row 248 did for the hold
+  stubs, or with a shorter sleep. This binds the next row that touches
+  that test file. Until then, a lane cleanup that runs after this file
+  waits 30 s before it calls a lone `sleep 30` a leak. The row 197
+  lanes scan only at lane end, about 15 minutes after pkg-bus, so they
+  can't see it (mos-1169). (2026-10-21)
+
+- **Row 66 live checks: the unslop notice on a live managed session, both harnesses.**
+  (mos-1186, Vikunja #454.) Row 66's gate asked for one landing session per
+  harness with a prompt that draws a known tell. Mos changed that gate. The
+  Claude Code session ran before landing on a scratch root from the
+  candidate tree (run r4ab24630d323, landed 2c38325ec). Pi ran launch only there (run r1dd94171bede):
+  this host has no credential pi reads until P19 #383 settles. Two live
+  checks remain. Claude Code: in the first re-pin whose tree includes row 66,
+  backup first (Q173). Pi: one full session with a tell after #383. Each
+  attaches the operator note on the RESULT, the next-turn correction and the
+  `unslop.jsonl` counts. (2026-10-21)
+
+- **Console tester listener: `testerNoSignIn` is a dead parameter.**
+  (Duckworth N2 on the row 196 manifest, REVIEW-m1; carried as C1 in
+  REVIEW-m2 cdbf7b64e, #1694 comment 30156.) Row 196 landed 7247d80c7
+  with the parameter and its comment still at `serve.mjs:472-475` and
+  passed from `webui/src/cli.mjs:109` and `sso.test.mjs:392`. Nothing
+  in `serve.mjs` reads it after the destructure. Remove it, or wire it
+  with a test. This binds the next row that touches
+  `packages/webui/src/serve.mjs`. (2026-10-21)
+- **Console library routes: the tester listener and `library.sync`.**
+  (Duckworth N5 on row 196 round 2, REVIEW-m2 cdbf7b64e.) At 7247d80c7
+  `startServer` (`serve.mjs:475`) takes none of `libraryFile`,
+  `libraryStatus` or `librarySync`, so the callbacks `cli.mjs` passes
+  do nothing yet. The row that adds the Console library routes decides
+  whether the tester listener gets `library.sync`. Duckworth's view is
+  that it shouldn't, because sync is a human write. (2026-10-21)
+- **Console library routes: four library codes still map to 502.**
+  (Dewey N2 on the row 254 manifest, #1759 comment 30173.) Row 254
+  gave six library codes a STATUS entry in `packages/webui/src/bus.mjs`.
+  `library-mapping-invalid`, `library-remote-invalid`,
+  `library-state-invalid` and `library-git` still fall through
+  `busStatus` to 502. The row that adds the Console library routes
+  decides their statuses and gives its `humanCall` for `library.sync`
+  a timeout over 130 seconds. (2026-10-21)
+- **T27 sweep test leaves two `sleep 60` children running.**
+  (Darkwing row 251 slot, darkwing-0113 and darkwing-0117; Dewey on
+  r2, comment 30168.) The sweep test spawns two detached shells,
+  `planted` at `host-run.test.mjs:528` and `decoy` at `:536`, each
+  running `sleep 60; :` with the run dir as `$0`. `sweepRunDir` kills
+  the planted shell by pid (`host-run.mjs:238`), and `t.after` kills
+  only the decoy shell. Neither kill reaches the `sleep` child, so each
+  one lives for up to 60 s after the test and trips any busy check that
+  follows. The fix is to kill the process group in both `t.after`
+  hooks: `process.kill(-pid, 'SIGKILL')`. Each shell is spawned
+  detached, so it leads its own group. `exec sleep 60` doesn't work.
+  The sweep matches the run dir in `/proc/<pid>/cmdline`
+  (`host-run.mjs:236`), and exec drops the `$0` that carries it, so the
+  planted process would survive and the "planted process killed" assert
+  would fail. This binds the next row that touches
+  `packages/bus/tests/host-run.test.mjs`. (2026-10-21)
+- **Real-model suite cases run outside the gate.** Row 244 moved
+  `test-task.sh` fork recall (M11) and user recall (M16) behind
+  `MOSAIC_LIVE_PROVIDER=1`, and `test-release.sh` activations to the mock
+  adapter. Before any re-pin whose tree changes `packages/harness` or the
+  session fork code (`scripts/mosaic-task.mjs` session and
+  `sessionForkFrom` handling, the pi adapter), an operator runs
+  `MOSAIC_LIVE_PROVIDER=1 bash scripts/test-task.sh` with the real pi
+  credential and a real `release.sh activate`, and records both results on
+  the re-pin row. Morgana's wording (row 244 BUILD.md), Webby N2 on row 244
+  r1 (#1757). (2026-10-21)

+## Queue
+
+Moved to `docs/plans/QUEUE.md` on 2026-09-13. This file holds only gaps.
+
+## Done
+
+- Ledger (piece 3, #1506): shipped cd0aa5fb, Gate D written 2026-09-12 (18.9 human messages per closed issue).
+- Relaunched seat shows the old last message (darkwing, Step 3 log, 2026-09-12): closed by #1512 relaunch activity, af4203ca. Filbert authored it; Darkwing and Dewey reviewed. The live board restart and Gate F remain separate.
+- Sage launcher hook uncommitted (2026-09-12): closed by the agents/sage launch files commit, Dewey review R1 revise, R2 approve (`agents/dewey/work/sage-launch-review-2026-09-26.md`), launcher test now covers sage.
+- Ledger counts T3 agent messages as human (2026-09-26, #1506): fixed in ef0020ad (Darkwing 6a, Filbert reviewed). `messageKind` now counts a T3 header as agent and the control-board sender as board. It changes no current count, because no source the ledger reads has a T3 header yet. That waits for the T3 thread source (Gate F).
+- Control board checked the bind address but not Host or Origin (2026-09-26, #1507, found by Dewey): closed by the board guard commit. `foreignRequest` refuses a non-loopback Host, a wrong port, userinfo or a path in Host, and any foreign Origin on every route. Dewey authored it, and Rocko approved it (`agents/rocko/work/board-guard-review-2026-09-26.md`, 5a12f08e). Rocko's one low finding: URL normalization accepts a root slash, empty userinfo and an empty query in Host, so the notes' wording overstates what the raw-syntax check refuses. No bypass was found.
+- Discord engine: leaked fake pi and the timeout gap in `busy` (2026-09-26, #1509): fixed in 3edb15eb (Darkwing 6b R2, Rocko approved, review ed5510a0). Tests stop the engine in `finally`. A turn pi never started now stops pi with exit 1 instead of guessing, and the unit restarts it. Known limit: see the open entry on wedge restarts.
+- Combined concurrent test hangs (2026-09-14, #1509): closed on evidence from 3edb15eb. At default concurrency the union passed 406/406 three times on the R2 snapshot and 408/408 on the commit's index, where clean HEAD had hung four runs out of four. The inherited-intermittency entry from 2026-09-15 stays open until a later run shows it is the same cause.
+- A nested `node --test` passes even when its tests fail (2026-09-26, #1508): closed. Queue A1 (34a72af9) clears NODE_TEST_CONTEXT on its own path. N13 fixes `test-foundation.sh` and `test-discord.sh`, each with a check that fails the suite if the clearing is lost. Darkwing wrote it (n13.patch 00868b2f) and Filbert approved it (e464be6c). Sage's grep on 2026-09-27 finds no other nested `node --test`: in scripts, only the two suites, `test-queue.sh` and `queue-commit.sh`, and in JS, only the queue test that covers the fix.
+- SetSpark service accepted any string as a decision approver (2026-09-26, #1509): closed. Fixed in shared-signals cc74d92 (Rocko approved R2, lead decision 24). The operations seat (T3 12fe8cda) deployed it to VM 1022 at 00:23Z on 2026-09-27. The running `service.py` hash matches cc74d92, and `/healthz` returns 200 inside the network and through the public tunnel. The read-only README survey found one row breaking the rule (DEC-009, Proposed, version 1), one open request that isn't ready (DEC-009's), and no Accepted decision with more than 16 approvers. No rows changed. DEC-009 stays as stored (lead decisions 21 and 28). The service now refuses approvals on it, so nothing can go wrong silently. Side effect: `up -d` also recreated caddy, about 20 s of edge downtime for all hosts. That is for the shared-signals deploy procedure to fix, not Mosaic.
+- Queue suite failed its live checks outside the canonical checkout
+  (2026-09-27, #1508): closed by Piece D, f539466f. `test-queue.sh` now
+  skips `verify` and `render --check` with a printed reason when the
+  toplevel isn't the recorded `canonicalRoot`. An index export passed
+  27/0, and the canonical checkout 29/0.
+- Queue: an owner listed as a reviewer blocked the row (2026-09-27,
+  #1508): closed by row 31, bb2fa970. `add`, `set reviewers` and `assign`
+  now refuse the owner as a reviewer with exit 2 and write nothing. Rocko
+  built it in the Gate G run, and Filbert approved round 1 (#1508 comment
+  26629, 8 of 8 mutants caught).
+- Queue follow-ups from rows 12, 13 and 31 (2026-10-04, #1508): closed by
+  row 33, 6fb50cc0. Filbert built it, and Darkwing approved round 1
+  (#1508 comment 26651).
+  - `genesis` refuses a map row whose owner is one of its reviewers (exit
+    2, nothing written). The check is on the map, not in replay, so a log
+    from before the rule still loads.
+  - The `assign` refusal now reads "can't assign row N to SEAT: SEAT is
+    one of its reviewers".
+  - `queue-commit.sh` compares HEAD with H before each canary and again if
+    the clean run fails. A moved HEAD exits 2 with "HEAD moved since H was
+    recorded"; the guard message is kept for a real guard failure.
+  - Every time and date the validator accepts must format back to itself,
+    so month 13, day 32, 2026-02-30, 2027-02-29 and 24:00 are refused.
+    The live log at rev 45 still replays.
+  - The cold-start failure (2026-09-27): not reproduced in 20 cold runs.
+    Each ran `node --test packages/queue/tests/` in a fresh tree, 10
+    shared clones and 10 exports, one after another. All 20 passed
+    148/148 (2960 of 2960). The 300 ms deadline test is unchanged. Counts:
+    `agents/filbert/work/queue-33/cold-runs.txt`.
+- CHAT-03 I1 round 2 follow-ups (2026-10-04, #1507): four of five closed
+  by slice 1 S5 (row 40, #1522; Dewey authored, Darkwing and Filbert
+  reviewing). The commit is named in the row's review record when it
+  lands.
+  - Engine command and `preArgs`: `engine` takes only `extraArgs`, `cwd`
+    and `envKeys`. The controller always launches the pinned Pi and
+    checks that at construction and at bind. The fake engine comes in
+    through a symbol key that JSON config can't carry (N24b).
+  - Engine environment: an explicit list (`ENGINE_ENV` in `pi-pin.mjs`)
+    plus `*_API_KEY` and `*_TOKEN` names from `engine.envKeys`. Nothing
+    else is inherited. `HOME` passes, so Pi reads `~/.pi/agent` unless
+    `PI_CODING_AGENT_DIR` is set (Darkwing F3).
+  - `escalating` is cleared when the force-stop fence throws (Darkwing F2,
+    races.test.mjs).
+  - Takeover then Enter in one chunk: input after Ctrl-T or Ctrl-O waits
+    for that action, in the same chunk or a later one, and also while an
+    earlier action is still pending, so it is judged as if typed one key

+## Row253 F5: legacy Case AS_USER supervision
+
+Tracked as row 276, Gitea #1781 (sage-2331), owner Gander, reviewer Duckworth, after row253.
+Brief: docs/plans/2026-10-22_case-sudo-legacy-followup.md, “Brief: supervised legacy AS_USER calls”.
+
+case1-accept.sh's legacy timeout330 around AS_USER talk and its AS_USER precheck, Claude version, PM launches and Node version diagnostics predate the new socket metadata/probe helpers. sudo's pty monitor can move them to a separate session; the old outer timeout does not prove their descendants are killed. The C4 repair in row253 covers only its new config query and peer probe. These legacy paths need the reviewed supervisor or a header explicitly explaining why each remains unsupervised. The follow-up must preserve the 300-second talk/reply contract, concurrent F5 scan, diagnostics and secret-output refusals, with fake-only session-hop tests and Sage's slot. No host or live unit change is authorized.
+
+Row 276 / #1781 also owns the case1 root-side capture/tools mutant counterparts (duckworth-0112 N1) and documenting the setuid-member cleanup refusal in the headers (N2). A member that changes uid and cannot be killed causes inner-cleanup refusal, never successful observation. N4 is addressed in row253 by allowing SID confirmation until the existing inner watchdog expires, instead of a separate 200 ms scheduling margin.

+# rules and be a factory file for --business. Every command that runs the stack's code runs as
+# `sudo -u USER -H env PATH=<node dir>:/usr/local/bin:/usr/bin:/bin` from /. Root itself reads ss,
+# /proc, the account database and file metadata, and runs these: systemctl show and is-enabled (F1,
+# P11), curl on the Console's loopback healthz (F2), sudo -l (P1, P3), sudo -u jarvis bwrap --version
+# and hostcheck.sh --check (P9), and node to parse managed-settings.json (F9). F9 runs node only when
+# --node is the pinned path and it and every directory above it are root's with no group or other
+# write. The script changes nothing on the host but the message F3 sends and its reply, and it never
+# opens claude-session.env. A bounded config/target query imports the copy only as the stack
+# user, with sudo and an empty environment. Root parses its two facts in bash. P10 uses the
+# fixed system Python, also as the stack user, for a read-only SO_PEERCRED observation.
+# The config/probe supervisor is fixed root-validated system Bash plus setsid
+# and sleep, after the uid drop: query inner/outer 5/7 s, probe 2/4 s. Root
+# independently bounds its sudo wait. Legacy AS_USER talk and diagnostics below
+# retain their old behavior and are NOT covered by this supervisor (F5 follow-up).

+# Root runs it from a root-owned checkout of the reviewed commit outside
+# <home>, never from the release, because <user> can write the release. It
+# writes both units under /etc/systemd/system as root:root 0644, runs
+# `systemctl daemon-reload`, enables both, then starts the bus and then the
+# Console (Q189). Both come back after a boot on their own. It never links
+# a unit file into place. Root only stats files under <home> and reads bounded
+# stdout from a config/target query run as the stack user through sudo. Root
+# never imports copy code. This adds sudo and GNU timeout to the installer
+# dependencies. The inner query supervisor runs after the uid drop: 5 s inside,
+# 7 s on root's wait. Fixed system Bash, setsid, sleep, timeout and head are
+# resolved and root-validated. Only the config query uses this supervisor.
+# It renders the default instance only.
+#
+# The library profile takes exactly these serve flags, each once:
+#   --port N (1..1023)  --business ID (the unit's)  --public-host NAME
+#   --auth-header HEADER  --allow-user ID  --send
+#   --proof-header NAME  --proof-file PATH
+# The factory profile takes --port N (1..1023) and --business ID, and an
+# optional bare --tester-socket marker. Retired tester TCP refuses. Only factory takes
+# --pm and --claude.
+#
+# On a re-install the installed units must equal the render in everything
+# but the copy id, and both must name one copy, so a re-pin or rollback
+# re-renders the pair together. A unit that was already running stays on its
+# old copy, since `systemctl start` leaves it alone; the script says so and

+# Draft(b): expected P10 reasons before diagnostic(a)
+
+Not derived from diagnostic output. No test edit is prepared or committed. The brief delegates P10 checks/outcome wording to DESIGN (docs/plans/2026-10-21_tester-socket-scripts.md:31). DESIGN.md:163-170 requires the failed reason to identify the failing observation, rather than accepting any unnamed line. BUILD.md:17 records the separate parent/socket/process/snapshot and peer checks. C4 refined failure classes in DESIGN-C4.md:84 and:91-95, with BUILD.md:175-177 recording distinct refusals.
+
+The approved prose names semantic classes, not a literal exhaustive code-name table. The expected bounded labels below name those classes using existing source labels, cited separately for transparency. They are not selected from (a). peer-malformed=probe is additionally explicit in mos1293. If the diagnostic reports a different class/code, send it to Mos before any edit, even if it would make an existing broad assertion pass.

+All existing status assertions and the boundary=failed/no-boundary=observed assertions remain. The draft adds exact reasons; it never weakens a status or changes a failure to fit observation. The special peer-uid-fields functional failure remains exit1. Product changes require Mos. A fixture-only repair can be considered only when the stub is shown to mask the intended fault, under mos1293.
+
+One scratch archive of0604d91fc is prepared at the path in PREPARE.json. Its only change logs every P10 line, reason and status immediately before the same existing assertions in the named loop. Both product scripts and shared fixture are exact base blobs. The COPY-PATH is not a commit/worktree. No source or test in the seat checkout is changed.
+
+On Sage CLEAR: create TMPDIR via mktemp-d /mnt/storage/scratch/tmp/gXXX, export it, invoke diagnostic-a/run.py with that grant. It gates with the busy check, uses timeout-k10 418 and outer448, pipefail/tee, records command/header/results and writes P10.jsonl. It refuses a second run if output exists. No diagnostic/syntax/Node execution has run while preparing this.
+
+## Duckworth0160 expected-set review
+
+All17 expected reasons accepted by source-only review. C1: assert the exact reason token, including its following space, for example `reason=probe `, or match the full P10 line. A prefix expression `/reason=probe/` is forbidden because it also accepts probe-inner-command and other probe-* reasons. C2: keep every existing status, boundary=failed and no-boundary=observed assertion. A fixture repair is limited to a mask shown by diagnostic(a), and an unexpected reason goes to Mos before any edit.
+
+N1 citation corrected: peer-error child failure is DESIGN-C4.md:84-85. N2: the existing peer-hang test at case1-accept.test.mjs:291 has a separate loose probe prefix; Duckworth says it is outside mos1292/1293 scope and does not bind this repair. No change to it is prepared.

+# Row253 integration onto 0fa7bf421
+
+Authority: sage-2463. New branch gander/row253-0fa7, rebase tip before these records 67224933425e9687bf366cd7ba7c31c1daa4e9f3. Both earlier branches remain unchanged. Nine commits replayed onto 0fa7bf421fc153a226b5f06ed484e089e48e23ba.
+
+One conflict: the first design commit's BUILD-LOG.md append. Kept upstream in full, then appended the row253 phase. The integrated log has the entire current base blob as its exact prefix. It stays outside the manifest and lands as a separate doc-only append after code. README merged automatically, retaining row253's tester-socket wording and row191's complete Instance processing controls section. No runtime or test conflict.
+
+Only packages/webui/README.md changes among the seven manifest entries. CANDIDATE-SHAS.json and MANIFEST.sha256 are refreshed. The old C4 packets remain historical exact snapshots; the README addition is the sole new manifest blob. Runtime scripts, focused test files and shared fixture remain byte-identical to the approved candidate.
+
+## Static test dependency inspection
+
+The row253 focused case1/case2 files read their two host scripts, generated fixtures, kernel proc data, the two service templates, and case2-precheck.sh. They import the shared case-sudo fixture, cli test helpers, business test helpers and seat sandbox helpers. Neither directly reads or imports the row191 changes in webui cli.mjs, serve.mjs, index.html, processing.js/css or processing-http.mjs. The cli.mjs/config.mjs in their scratch copies are stand-ins written by the fixtures, not the repository Console code.
+
+The required WebUI whole suite does consume row191's changed modules and UI, including the processing/browser/shell tests now present on the integrated base. The full CLI suite also runs against the new base and scripts/mosaic. No focused test, suite, syntax execution, browser, probe or host experiment ran. Dependency inspection used source reads only.
+
+range-diff.json covers the nine replayed commits. patch-ids.json lists each old/new pair; the final record/manifest refresh commit has no old counterpart. The requested exact range-diff through the final committed tip is sent with the handoff. Publishing uses only the repo helper and waits for a clear busy check.

+# Row253 final integration after264a
+
+Authority sage-2698. New gander/row253-264a on84f53540d; previous branch retained. Eleven commits replayed with no conflict. All eleven range-diff pairs and full patch-ids equal. Rebased tip before this record b9d3d4c75c78aa6b06aefd734da781bef9b7f1da.
+
+Only DEFERRED changes among the seven manifest blobs, preserving the new base as an exact byte prefix. Six other blobs remain unchanged, including both host scripts, both focused tests and shared sudo fixture. New manifest 735fa2d7405d01ace8eb7aab366753fa5b1877cf8044b0151cb2113a0502bc1f. BUILD-LOG remains an append outside the landing manifest.
+
+264a reaches the focused tests through Store loaded by CLI helpers. The new base includes schema3l, migrations/3k-3l.sql and matching store hash. The focused tests pin neither3k/3l nor schema bytes. No product/test/assertion repair. Duckworth0132 already checked this dependency statically against264a r9. This packet also lists actual landing changes. T46 stack-release.test.mjs reads actual schema and will run whole.
+
+The required whole-file union conservatively includes every .test.mjs changed upstream from385a to84f plus both own focused test files. Shared case-sudo fixture is exercised by its two importers; schema-3k.sql is a migration fixture, not a standalone test. Whole-test-union.json has 27 runnable files. No result carries. These runs await a focused CLEAR before publication and Duckworth rebase check; the whole gate needs a later CLEAR.
+
+N9 remains the exact case2 test: inside a session's sandbox a bind below1024 fails with EACCES, and a bind on a free high port succeeds. Its skip reason comes from sandboxProblem() at gate time and will be copied verbatim. Other environment/provider/canonical-root skips will be named too.
+
+SHELL-LIMITS.json stays as prepared under sage-2659. Every scripts/test-*.sh blob matches the previous base; the only changed script upstream is stack-release.sh. Current limits retain their receipts and3x rule. No tests, Node, syntax commands, browser, host probe, queue command or push ran.

+Required whole files:

+# Row253 integration onto 378a76b85
+
+Authority: sage-2348. New branch gander/row253-378a; gander/row253 remains at 9e916c454. Rebased range c3d88840c..9e916c454 onto 378a76b85; rebase tip before these records is 2f466464cccfe7b4f2522936a7f8409b74af7b5c.
+
+Two conflict resolutions, both documentation:
+
+1. First design commit, BUILD-LOG.md: kept every upstream appended line, then appended the row253 design phase. The integrated log has the complete 378a76b85 blob as its byte-identical prefix. Later row253 phase entries replayed normally. It remains outside the manifest and lands as a doc-only append after code.
+2. Runnable repair commit, DEFERRED.md: kept current upstream content and appended the row276 / #1781 F5 entry. That commit had incorporated upstream changes on the old branch; the rebase correctly omits changes already on the new base. The later N1/N2 entry replayed normally.
+
+No runtime or test conflict. All seven final manifest paths, including DEFERRED.md, are byte-identical to 9e916c454. Manifest digest remains 34d52cc500b2de855142daca4e293bbf05ff56d1c98bb94a061edabfc117e3e5. No entry changed. CANDIDATE-SHAS.json also remains valid.
+
+range-diff.json stores the exact command and stdout. patch-ids.json gives every paired commit. Six commits compare equal; design and runnable repair differ only through BUILD-LOG context and DEFERRED upstream incorporation described above. No test or syntax execution ran. No push helper ran during Darkwing's slot. Sage publishes both own branches in the next gap. The whole gate remains held for the manifest review and CLEAR on this integrated candidate.

+# Row253 re-integration onto 385a7194c
+
+Authority: sage-2659. Branch gander/row253-385a preserves all previous seat branches. Source tip before this packet: 141b79c293d78e78b9ce05bcf0fcaa18ba4d6963. Ten commits replayed from 0fa7bf421..8de88458d onto 385a7194c.
+
+The first design commit conflicted only on BUILD-LOG.md. Kept all upstream bytes and appended the row253 phase; later appends replayed. BUILD-LOG and DEFERRED keep 385a7194c as exact byte prefixes. BUILD-LOG stays outside the manifest and lands by append after code. README merged automatically; its four row253 replacement pairs are exactly the same as before. The row278 thread-claims documentation stays present. No runtime/test conflict or repair.
+
+range-diff.txt identifies two context-only changes (commits1 and6), both BUILD-LOG context. All other pairs equal. patch-ids.json records all ten old/new pairs. The full patch-ids for commits1 and6 change because their BUILD-LOG context changed. Excluding BUILD-LOG, all ten patch-ids match. No runtime/test change.
+
+The new seven-path manifest digest is 72a70e99ba0416ceb1f63ed737132ebbeb212332d1441c362b3dfa6c8b00209c. Only DEFERRED and README differ from8de88458d. The two host scripts, two test files and shared sudo fixture are byte-identical to Duckworth's approved candidate. manifest-drift.diff is the required 0fa7bf421..385a7194c diff restricted to the seven landing paths; upstream changed only DEFERRED(+79) and README(+9). drift.json lists every upstream changed path separately.
+
+## Test reads and pins, source-only inspection
+
+The focused case1/case2 tests read the host scripts and temporary fixture files. case2 also reads case2-precheck.sh and the two service templates; those three assets did not change in 0fa7bf421..385a7194c. Both tests write their own config.mjs and webui cli.mjs stand-ins into scratch copies. They do not import the real Console cli/serve/public modules, and row278's real Console changes require no focused fixture change.
+
+The earlier dependency claim is widened here: both tests import cli/tests/helpers.mjs, which imports Store/Broker. Store reads schema.sql and the migration chain and checks schema bytes at module load, even when a particular test only calls tmp(). Store, broker, schema.sql and 3j-3k.sql changed upstream. drift.json lists the conservative literal-import closure and its nine moved modules (including business access/credentials/role/vocabulary and library mapping). The closure includes generated-source literals and is not an execution trace. case2-precheck.sh also dynamically imports the actual cli config and business index; business imports changed and the whole focused file must cover them. cli config itself did not change.
+
+case2 imports seat/src/sandbox.mjs, as Duckworth0116 N9 identified. It did not change since0fa7, and its sandbox test still may skip on sandboxProblem(). Report that exact skip in the gate; do not assume zero. The actual sandbox binder reads the repository file inventory, so changed dependencies are covered by the whole-file run if available. No host experiment was run here.
+
+Whole CLI covers changed format/grants/instances/lifecycle/tester/stack-release tests and real cli modules. Whole WebUI covers row278 and its existing shell fixture repair on this base. stack-release.test.mjs T46 at916 reads actual schema.sql and classifies every table; Store's schema hash and migrations are another live consumer. Whole-shell calls can load queue/business/bus consumers too. No row253 test has a literal 3k/3l version pin to update by assumption. The relevant whole-CLI schema fixture strings in stack-release-fixture.mjs model old target copies intentionally; they are not pins on the current bus schema. No assertion is changed to anticipate264a.
+
+264a's 3k-to-3l schema change has not landed on this base. Before CLEAR, compare its store/schema/migration and any test or asset it moves, and integrate on a new branch if Sage names a new base. A seven-manifest-path-only check is insufficient because the focused import closure reads schema at load time. No result carries from the historical row253 gates after the C4 product repair.
+
+## Gate preparation, no runs
+
+SHELL-LIMITS.json uses the same successful whole-file receipt set as row278, plus every row278 run3 whole-shell result from385a7194c. Each limit is ceil(3*longest)+120 seconds. Foundation's newer39.901s receipt replaces39.708726s; its limit remains240. Other maxima remain the row196 receipts. All ten scripts have receipts;900 is the no-record fallback only. Each current script hash is pinned. No scripts/test-*.sh changed.
+
+window.py now uses these whole-shell wrappers: timeout -k10 LIMIT bash scripts/test-X.sh, with the outer harness wait30s later. driver.py marks exits124/137 as timeout and never reports them as kills. These are harness-only changes; no product/test/fixture changed. No command was executed by either harness. All40 proposed string targets still occur exactly once, checked as bytes in uniqueness.json without running syntax or tests. Full C4 timing and kills remain unverified.
+
+The next action is Duckworth's integration read, followed by Sage's CLEAR after281 and264a. No Node, test, syntax command, browser, probe, queue write, helper push or live action ran during this re-integration. Publishing the new branch needs a gap because the repo helper runs Node.

++- **Creative instances: the human can't delete one.** (Sage's ruling
++  sage-2164 on the row 194 b4 rebase, #1692.) Row 213 put the creative
++  definitions in END_PROTECTED, and row 194's `deleteRefusal`
++  (`instance-settings.mjs`) refuses END_PROTECTED for every actor, so
++  the human can't delete a companion instance and fire refuses one too.
++  The Agents page hides Delete on the listing's `endProtected`. The fix
++  threads the actor through `deleteRefusal` and the launcher's delete
++  pass, so the human may delete one and the tester may not
++  (`creativeHumanOnly`). Until then, the human can delist
++  (instances.set launch: false) but neither fire nor delete removes a
++  creative entry (sage-2166). The row covers fire and delete together;
++  Sage files it. (2026-10-21)
++  Closed for delete by row 256 (#1761, REQ-COS-3): `deleteRefusal` takes
++  the actor, so the human deletes a creative instance and any other actor
++  is refused `organization-creative-human-only`, and the listing's
++  endProtected is the same check for its reader. Fire still refuses every
++  END_PROTECTED instance, by the row 256 brief's ruling, not by a code
++  change. (2026-10-22)
++- **A fire stuck between step A and step B has no human escape.** (Webby
++  N4 on row 194 b5, webby-0094; Sage's ruling sage-2241, #1692.) The
++  broker's chief fire records `fire.stopped` at step A, and `#firing`
++  refuses every launch and take of the instance until a `fire.done`. The
++  events are in the store, so a bus restart doesn't clear them. Row 194
++  b6 runs the writer's checks against the file before step A
++  (`instance.fireCheck`), so a keep the bus hasn't loaded no longer
++  strands an instance. A step B that keeps refusing still does: a
++  credential revoke that fails every time, or a file a human changed
++  between the check and the write. Each repeat fire runs step A again
++  and refuses at B. The fix is a human verb, never an agent one, that
++  records the end of the firing (a `fire.done`, or a new
++  `fire.abandoned` that `#firing` also counts) with a reason. Its test:
++  a fire whose step B refuses leaves the instance `instance-firing`, the
++  verb as the chief or the tester refuses, and the verb as the human
++  clears it so the instance launches again. (2026-10-21)
++- **A fire's done with more than 64 stops refuses, and nothing flags a
++  run left alive.** (Webby N2 on row 194 b8 r2, webby-0100; Sage's ruling
++  sage-2290, #1692.) `lifecycleDone` caps `stops` at 64 and refuses
++  `invalid-request` above it (`broker.mjs`). The launcher's fireStop has
++  already signalled every run through stopRun by then, so the killed runs
++  are dead. But the refused done writes no lifecycle.end.killed or
++  lifecycle.end.alive event and no lifecycle.done, and the end request
++  stays taken. A run the stop left alive, or couldn't confirm (unknown),
++  gets no Console flag. The fire itself is unaffected, because
++  `fire.stopped` and `fire.done` are written at the verb. No MVP instance
++  comes near 64 runs. The follow-up row either raises the cap or splits
++  the done. Its test: a fire's done over the cap refuses, and the runs it
++  left alive still get the alive flag. (2026-10-22)
++- **A fired or deleted instance keeps its grants.** (Dewey on the row 236
++  rebase look, dewey-0815; Mos mos-1271; Sage sage-2558.) Row 194's
++  `instance.fire` and row 256's delete revoke only the roles entry's
++  credential services through `revoke()` in `runtime.mjs`. The agent's
++  host grants (row 235) and its Gitea user and token (row 236) stay live
++  until a human runs `mosaic hosts revoke` or `mosaic grants revoke`. The
++  Console has no revoke route and doesn't say a grant is left. Row 281
++  (#1786) closes it: a fire or a delete revokes every host and Gitea grant
++  the instance holds, fail closed, with a test for each kind. It lands
++  before the .53 Case 1 install hires an instance with a grant.
++  (2026-10-22)
++
++- **The runs suite doesn't gate a change to `scripts/mosaic-task.mjs`.**
++  (Dewey N7 on row 191, repeated on the Vikunja 502 review.)
++  `packages/runs/tests/task-cli.test.mjs` spawns `scripts/mosaic-task.mjs`,
++  but row 191's gate didn't run the runs suite. test-task.sh covers the same
++  list and show paths, so nothing is known broken. Binds the next row that
++  changes `scripts/mosaic-task.mjs`: its gate runs the runs suite whole.
++  (2026-10-22)
++
++- **Row 277's M8 is killed by a rethrown error, not an assertion.**
++  (Duckworth N1 on the row 277 manifest round, duckworth-0127.) M8 makes
++  the thread.claims catch in `packages/cli/src/cli.mjs` rethrow. The stubbed
++  `processing-halted` error then escapes `main` and fails
++  `packages/cli/tests/tester.test.mjs:149`. That counts as a kill, but no
++  test pins that `main` resolves on that path. Binds the next row that
++  changes `packages/cli/tests/tester.test.mjs`: add the resolve pin so M8
++  dies on an assertion. (2026-10-22)
