 2026-11-04T17:07:37Z | Codex implementation sub-agent, t3/placeholder | #772 / row 334 F2 Case 2 proxy upgrade and rollback | Before: c098fa022 rejects the bare --proxy args line; read_old and stop/recovery cover only bus and Console, so a proxy hub cannot upgrade or roll back. After: accept only the bare flag, require all selected installed units to name one copy, refuse missing/linked/malformed/disagreeing proxy units and an installed proxy without its flag before stopping anything; stop Console, bus, proxy, wait for each, and preserve --proxy through both new and old renders. A2f starts proxy first and refuses a failed proxy restart with all three stopped; all rollback-failed cleanup includes the proxy. Header exit-code meanings and the ordinary two-unit path remain unchanged. Section 7 documents the flag and lifecycle. Nine added tests cover upgrade, explicit rollback, failed-upgrade restoration of all three unit files, A2f recovery/start failure, final stopped cleanup, no-proxy compatibility, malformed args, installed-unit refusals, and the real factory renderer re-pin/rollback. RED: focused #772 3 pass/5 fail/0 skip on the base, all five failures at args-unreadable --proxy. Corrections: first GREEN candidate 7/1/0 exposed the render stand-in using a different checkout path; a --checkout override was unsupported (6/3/0), so the stand-in now runs from the same fixture clone as setup; final focused 9/0/0. Required final gates (pass/fail/skip): node --test packages/cli/tests/stack-upgrade.test.mjs 34/0/0; node --test packages/cli/tests/case1-accept.test.mjs 53/0/0; node --test packages/cli/tests/case2-install.test.mjs 28/0/0; node --test packages/cli/tests/case2-unit.test.mjs 88/0/0; bash scripts/test-case2.sh 21/0/0. The four matching test files were found with git grep. Initial case2-install 6/22/0 lacked node_modules/yaml; initial scratch acceptance 13/8/0 lacked the installed dependency tree and passed after lockfile-only npm ci --ignore-scripts with distinct empty user/global configs and a scratch cache. The first npm setup attempt refused duplicate /dev/null config paths before installation. Every test invocation set TMPDIR with mktemp -d /mnt/storage/scratch/tmp/XXXXXX. bash -n and git diff --check passed. Logs: /mnt/storage/scratch/tmp/JBjOT3/ (RED/intermediate/focused and all required gate logs, npm setup, verified-source.sha256). Queue next refused the linked worktree; canonical queue movement remains with the coordinator. Fixture systemctl/sudo and synthetic configs only; no live host/unit, real credentials, ~/.config/mosaic-*, ~/.mosaic or /srv/mosaic access. One local commit authorized; no push, merge or deployment. No remaining code limitation; live .53 acceptance is outside this assignment.

The owner now picks the mode (new autonomous, new guided, existing project), answers the PM's questions and confirms an attachment with buttons; no copy-to-terminal step. BUS: 3p->3q append-only migration widens the request_events kind CHECK (bootstrap.completed, question.asked, question.answered, attach.selected, mode.changed, cancelled) and keeps rows, seq and guards; reduce gains question, selection-attach, mode and cancel state; PM-only request.question; owner-only request.answer.console, request.attach.console, request.mode.console and request.cancel.console (the cancel verb is beyond the brief's list, needed for its Cancel rule) join request.get.console and request.projects.console in CONSOLE_VERBS (8 verbs, #human CLI guard untouched, agent intake verbs keep their names, ROUTED and roles/*.json untouched). Every write replays a same-op same-digest call as the current state, a different digest is request-operation-conflict, then revision, phase and question checks. A guided answer is an attributed human.input linked to question and request, once per op, secret-scanned, never a PRD approval and never a rewrite of the spec; the PM continuation is enqueued after commit. Attach records the pick from the authorized picker and the PM proposes exactly that project as a confirmation decision (a propose that differs is request-attachment-mismatch); nothing is mapped on the pick. A mode change takes the expected revision and mode_revision, bumps mode_revision and leaves the bound plan as evidence, so a pending autonomous approval or dispatch admission bound to the old mode_revision no longer matches at the next action. Cancel withdraws an open selection decision (pre-task decisions are blocking:false) or appends cancellation and keeps a created project and its mapping as evidence. thread.messages adds the request id to human instruction rows for the owner only. WEBUI: src/request-http.mjs routes GET /api/requests/:request, /projects, /draft and POST /answer|/attach|/mode|/cancel through consoleCall as the signed-in (provider, iss, sub); writes need the signed-in owner, a single same-origin Origin, Sec-Fetch-Site same-origin, application/json, an exact key set, a bounded body (4 KB, answers 64 KB / 8000 characters) and a live() recheck before the spawn; the draft read answers draft-unavailable (503) until Task 4 adds request.draft.console. serve.mjs and cli.mjs take requestRead/requestWrite (sso and send required, refused on the tester listener) and /api/config reports requests and requestWrites to the owner only. Page: public/requests.js mounts under the owner's latest three chat messages that opened a request (chat.js emits the mounts and calls MosaicRequests.mount after each paint), renders every bus string escaped with control and bidi characters shown as \uXXXX, answers the mode decision through the existing /api/decisions/:id/confirmation and /resolve pair, stores an answer in sessionStorage before sending it, and after a lost response reads the request first and resends the same op only on the owner's click. Nothing is retried by the page. Sign-out clears the panels and stored answers. RED->GREEN: packages/bus/tests/request-console.test.mjs (15), packages/webui/tests/request-http.test.mjs (14), packages/webui/tests/request-browser.test.mjs (12, real Chromium; browser.test.mjs passes 1/1 so the host browser limit did not apply). Existing pins updated as required consequences: 3q schema pin in 13 bus test files, console-decide N4 verb list (2 -> 8), browser.test.mjs script list (+/requests.js). GREEN: webui npm test 538/538, bus npm test 1492/1492 (the first full run had one failure, model-final-completion 656 FIFO startNice 16 !== 19, the same niceness flake recorded for Task 2; the file passed 21/21 alone and the full rerun was green), request-intake plus request-bootstrap 70/70, zero skips. Limits: until Task 6 the PM continuation after an answer is a plain INFO message; the draft PRD view has no panel until Task 4; the owner's attach pick is lost if the PM later appends a different setup wait; mode change is refused during bootstrap; a cancel queues behind an in-flight bootstrap; an open non-selection decision on a cancelled request is not withdrawn; a session being cleared or retired makes the answer fail closed; request_project_events kinds remain unwritten; 3q may collide with the parallel #802 migration number. Logs /mnt/storage/scratch/tmp/0pihwW/. Not executed on any running instance or Console; local commit only, no push/merge/PR/deployment.
 2026-11-04T17:18Z | Claude Sonnet 5.5 implementation sub-agent, t3/console-request-intake-controls-r2 | #797 / Gitea #1839 lifecycle Task 3 rebase | Before: Task 3 sat on 6dd4f92b0 with its own 3p->3q migration and its own request-level request.mode.console; origin/refactor had moved to c098fa022, whose Task 4 core already shipped 3p-3q.sql (prd.submitted, prd.activated, prd.invalidated, mode.changed) and a project-level modeConsole. After: the two reviewed commits (7fd0c3562, c52218c65, still reachable) are replayed on c098fa022 as e9a12beb1 and e6837f76a, plus one webui reconciliation commit. MIGRATION: Task 4's 3p-3q.sql is untouched and byte-identical to c098fa022. Task 3's step is 3q-3r.sql and SCHEMA_VERSION is 3r. 3q-3r rebuilds request_events with the 15-kind union (opened, selection.proposed, selection.staged, selection.confirmed, setup.wait, bootstrap.stale, bootstrap.completed, prd.submitted, prd.activated, prd.invalidated, question.asked, question.answered, attach.selected, mode.changed, cancelled), so every kind Task 4 added is kept and the three Task 3 kinds are added; rows, seq, sqlite_sequence, the index and the six guard triggers carry over. schema.sql is the same union and SCHEMA_SHA256 was recomputed (4dfc55b4...2092). The 3b..3r chain replays to the fresh schema digest (comment-migration, schema and request-console migration tests; migrate-schema prints bus schema 3r ready). MODE: Task 3's request-level mode path (reducer branch, lifecycle changeMode, broker recordMode, MODES and MODE_PHASES, its two request-console tests and the C1 mode edge test) is removed. request.mode.console is Task 4's modeConsole: it moves the project's mode revision and every attached request, returns each to discovery with wait request-mode-changed, and refuses a stale mode revision as request-mode-revision-conflict. It sends no human.input or PM message, so it has no messaging edge to check; C1 still covers answer, attach and cancel. WEBUI: the mode route keeps its wire shape; request-mode-stale and request-mode-unchanged (codes no bus emits) became request-mode-revision-conflict (409), the mode copy and the request-mode-changed wait label describe Task 4's behaviour, and the draft route now relays Task 4's { candidate, prd, requirements } reply (the candidate must name the request) with prd-candidate-required as 409. CORRECTIONS to the 04:05Z entry above: it says 3p->3q, 8 console verbs and a request.mode.console that bumps mode_revision without leaving discovery; on this base the migration is 3q->3r, CONSOLE_VERBS has 10 entries and mode is Task 4's. TESTS: bus 1536/1536, webui 540/540 (one earlier whole-directory run failed decide-sso on a browser EPIPE and passed alone and on rerun), targeted request-console, request-intake and request-bootstrap 108/108, request-http and request-browser 28/28, prd-activation 21/21, project prd 6/6; zero skips. Not pushed.
 ### 2026-11-04 — Lifecycle Task 5b: scoped requirements and Git admission (#797, #1839)
 Before: Task 5a create recovery was already on `origin/refactor` at `103168614`.
 Task 4 (`76207fe48`, still under review) was cherry-picked as
 `1627e24d79da00a5a6c393fd0b15cea4362bdb1d`; both append-only log sides were kept.
 Task creation still used a private Stack requirement ID set, and Git admission did
 not bind a task to its product. The queue command refused this linked worktree;
 this session followed the owner's explicit Task 5b implementation assignment.
 After: broker discovery and host create admission use Task 4's catalogue, with
 checks during planning and immediately before admission. Product creates require
 request, requirement, project key, exact approved snapshot and stable op, resolve
 the board from the confirmed request, and refresh tracker membership/installation
 and role/session authority. Creation evidence retains TaskScope, PRD version and
 records/spec commits, including recovered creates under original attribution.
 Filters/trails distinguish colliding requirement IDs. Explicit host startup binds
 the baked catalogue only to the committed Stack identity with foundation ancestry
 and exact repository PRD/catalogue bytes; derived products cannot borrow it. Legacy
 unscoped discovery keeps its response, while intake never falls back. Host injection
 preserves Broker's sandbox import closure. Git socket/process/runtime pass the code
 project before bundle bytes; push recording, review and export recheck the binding.
 PM tool schemas carry the scope fields. No migration; scope uses existing JSON
 evidence. `requirements.json` and its consistency test are unchanged.
 Verification: new scope/recovery/Git tests **35/35**; required compatibility command
 **107/107**; `npm test` in tasks **132/132**, in bus **1501/1501**; additional CLI
 configuration/PM tool tests **32/32**. Every final run has zero skips, failures or
 cancellations, using a fresh `TMPDIR` under `/mnt/storage/scratch/tmp/XXXXXX`.
 Logs: `/mnt/storage/scratch/tmp/task5b-{newtests,regression,tasks,bus,tools}.log`.
 Red tests caught missing scope validation, stale tree admission, derived-product
 builtin binding and missing PM schema fields. A preliminary full bus run exposed
 an import-closure regression, tester refusal ordering and three managed-launch
 timeouts; host injection/refusal ordering fixes passed the targeted 35-test run
 and the final full suite. A subsequent full run stalled in the existing scratch
 SSH fixture; only its owned test child and scratch daemon were terminated, the
 interrupted evidence was kept at `/mnt/storage/scratch/tmp/task5b-bus-interrupted.log`,
 and the isolated full rerun passed. All started runs were joined before completion.
