fix(sys1): count project system types in the restore guard and admit the CLI verbs

Sol review sys1-review-r1 (changes 3): - P1: project_system_types joins stack-release.sh COUNTED and the T45 LISTED pin; the post-backup refusal and in-run recount tests now cover it. - P2: the CLI channel admits project.system-types and project.system-types.set; a new test drives both through run() and the real channel module (1/1 red without the fix). - P2: the #811 migration-reader pin moves to 19 steps ending 3t-3u.

 2026-11-09 UTC | Organizations friction round, landings #1876-#1881 (#1873) | Before: refactor 00ef0bd30. A Console launched by a relative path showed Request status unavailable, the overview printed the north star as raw markdown, packages/business and the business command spellings were the only names, Quick Setup ended with no route to a north star, an archived org could not be restored from a fresh page, and a dead bus after setup had no browser control. After, each through one Codex Sol xhigh review round plus a lead or builder fix round: #1876 re-execs a relative Console launch with its absolute script path (build 744753d7e, reproduced 121/0; review APPROVE 0/0/1). #1877 F1 renders the north star as sanitized markdown with a short preview (review APPROVE 0/0/1; live retest 4/0 twice). #1878 rename stage B moves packages/business to packages/organization and adds the org command spellings, keeping the business ones and their messages (builder 6828/6, see report; review CHANGES 0/1/0, fixed in e19db4009). #1879 F2 adds the onboarding interview after Quick Setup and on the project page, with human-only north-star approval (`mosaic project north-star --approve`) and no new agent grant (builder 411/0; review CHANGES 0/1/1: a refused start left its button disabled, fixed in 5937a977f along with the P3 stale approval capability). #1880 lands the U0 unified workspace samples, approved by Jason with the four-tile logo kept; the module names stay undecided at his request. #1881 E2E round 5 fixes restore from a fresh page, show an owner bus Start whenever the org list reads the bus down, say room changes are unavailable on org Consoles and recover the composer (builder 258/0; review CHANGES 0/1/0, 231/0: Settings kept Done after the bus died because only opening the org reread health). Lead fix fdd6658a6: every org list read is announced and the open setup redraws on a flip, and app.js reads the list before bus-status so a failed bus-status read cannot skip it; regression red on 8a8edc44b, 18 touched webui files 199/0 (Node 26.12.1, one file at a time). uiorg redeployed at fdd6658a6, 19:53Z. Open follow-ups: a down bus offers both the F3 banner Restart and the Settings Start, focus can move when setup redraws, and a Console stop also stops the org buses it started.

 2026-11-09 UTC, organizations F3 (#1873, PR #1884, a8f9f0957). The WebUI restarts the Console (supervised Consoles exit and `mosaic console start` relaunches them), restarts an organization's bus from the bus-down banner with a done receipt, and sends the owner's routing, agent, instance, name, assistant, limits and model proxy writes to the selected organization's bus. Routing apply lists how a change reaches each saved agent and offers Restart NAME now. Console restarts, bus restarts and routing, agent and instance changes append to `<dataRoot>/console/actions.jsonl`. Builder plus two refactor merges: combined list 354/0 on 999d173fd. Sol review CHANGES 1/0/1. P1: on a `--dev-local-owner` Console a local agent can send the right Origin and Fetch Metadata headers and reach these controls. The pinned startup warning and the accepted no-auth dev flags already cover this, but the README claimed no agent reaches them. Lead decision: correct the README and file the cooperative local-agent peer refusal as #1883, without building it in this round. P3: the instances route wrote no trail line. Fixed in 0a73279d6; the regression test fails on 999d173fd and passes on the fix. After the refactor merge, 25 touched or README-reading files 195/0 (Node 26.12.1, one file at a time, env -i). uiorg redeployed at a8f9f0957, 22:45Z; live config offers consoleRestart and org settingsSend. Correction to this session's process: after the test run completed I replied "No response requested" and stopped until Jason asked.

 `mosaic console start --dev-local-owner --dev-insecure-bind ADDR --dev-allow-host NAME[,NAME...]` opens that dev owner Console to other machines, for UI testing from another device on a trusted LAN. It has no sign-in: anyone who can reach ADDR:PORT acts as the owner. Start, and `mosaic console status` while that Console runs, print `WARNING: dev owner Console listens on ADDR:PORT with no sign-in; anyone who can reach it acts as the owner.` on stderr. ADDR is `0.0.0.0` or an IPv4 address, and a specific address must also be one of the names. NAME is a host name or IPv4 address without a port; give several as one comma-separated value. The Console answers only `NAME:<bound port>` and the loopback names, and takes a write only when Origin is `http://` plus that same Host. A browser on such an http origin sends no Fetch Metadata, so for an allowed NAME a write with that exact Origin and no `Sec-Fetch-Site` counts as same-origin; a `Sec-Fetch-Site` the browser did send is still checked. Both flags are refused without `--dev-local-owner`, and `--dev-insecure-bind` is refused without a `--dev-allow-host`. SSO, preview and tester Consoles stay on loopback. The Console state file records `bind` and `allowHosts`. `mosaic console status` prints the state as JSON (`bind` is `127.0.0.1` for a loopback Console) and never moves a stale state file.

+`mosaic console restart` and `mosaic org reload ORG` are the Console's Settings controls (F3) from a terminal (U1, #1873). Each sends one request to the running Console named in the instance's console state, as the page sends it (the Console's own Host and Origin, `Sec-Fetch-Site: same-origin`, a JSON `{}` body), so the Console applies the same owner, `--send` and origin checks and writes the same action trail, `<dataRoot>/console/actions.jsonl`. Both refuse inside an agent run (exit 3) before reading anything, and refuse with exit 3 when no Console runs. `console restart` works only for a Console started in the foreground by `mosaic console start` (otherwise the Console answers `not-supervised`); it waits up to 30 seconds for the relaunched Console to answer and prints `{"outcome":"restarted","from":OLD,"boot":NEW}`. `org reload ORG` restarts a running bus or starts a stopped one and prints the Console's done receipt. A request that left but got no answer is reported as outcome unknown (exit 1) and is never retried; check `mosaic console status`, `mosaic bus status ORG` and the trail. `mosaic bus restart ORG` remains the trail-less host verb.

jason.woltje	2c6556ab1e	fix(sys1): count project system types in the restore guard and admit the CLI verbs Sol review sys1-review-r1 (changes 3): - P1: project_system_types joins stack-release.sh COUNTED and the T45 LISTED pin; the post-backup refusal and in-run recount tests now cover it. - P2: the CLI channel admits project.system-types and project.system-types.set; a new test drives both through run() and the real channel module (1/1 red without the fix). - P2: the #811 migration-reader pin moves to 19 steps ending 3t-3u.	2026-11-09 18:46:36 -06:00
jason.woltje	f4bfd3a744	feat(plugins,organization): system types as a plug-in kind (REQ-SYS-1, #1873 ) Adds the system-type kind with five modules (coding, creative-writing, marketing, montage, business-management), an org-level enabled list validated fail-closed, project selections limited to the org's list, read verbs, and bus migration 3t-3u. REQ-SYS-2 toolsets are designed and deferred: they need a role authority contract.	2026-11-09 18:46:35 -06:00

jason.woltje	2109458b3f	feat(webui,cli): U1 cross-organization read model and console verbs (#1873 ) GET /api/workspace on the dev-local-owner Console: one snapshot of projects, sessions, inbox, tasks and per-org metrics across every organization the owner belongs to. Membership reuses the org list's admission (organizations.members); each org is read over the same per-org options the org pages use, with one deadline per org (4000 ms) and a state (ok, down, starting, timeout, invalid) with a time. Every row carries its org id; decide commands carry --org. Granted users and the tester get 403 owner-only. Polling at 10 s, no push. mosaic console restart and mosaic org reload <id> call the Console's F3 routes (POST /api/console/restart, POST /api/orgs/<id>/restart/bus) so gating, proof and trail are the Console's own; both refuse inside an agent run first. The cross-org assistant read is designed and stopped: it needs a new broker read verb or role authority.	2026-11-09 17:54:06 -06:00

jason.woltje	7a97cfc4f3	fix(bus): make the private store root at start when a reference names the store (#1886 ) Adding an agent with a store credential on an instance with no <configDir>/secrets/agents left the bus unable to start (credential-file): Credentials refuses a missing store root, and only issue() made it, which needs a running bus. Start now makes the root (0700) the same way issue() does, only when some reference has store: true. Credentials' own refusal (credential-store T1) is unchanged, and a root with loose modes or a symlink still refuses start. Tests: two new credential-verbs tests; the creation test fails on `483eccb3d` with credential-file. All 171 bus test files run one at a time: 1713 pass, 0 fail.	2026-11-09 17:10:09 -06:00
