 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. Open follow-ups: defect l (a bus restart after adding a credentialed agent can refuse to start), the bus restart refusal code, a stale-lock Recover control, one control for banner Restart and Settings Start, #1883.

+2026-11-09 UTC, PRD 1.20 and defect l (#1873, #1886; PRs #1887 03fe321b1 and #1888 7a97cfc4f). PRD 1.20: Jason approved draft 2 at 22:57Z ("The file looks fine other than that"; the Montage module name stays deferred). The PRD now has 118 requirements, with REQ-WS-1..8, REQ-AGENT-1..3, REQ-SYS-1..2, REQ-ACCT-1..2 and REQ-SETUP-1..2 added and REQ-ASSIST-1, REQ-USER-1, REQ-TASK-1 and REQ-WEB-3 amended. Builder Codex Terra xhigh declined to commit because stack-copy failed 20/1 (node-gyp missing from the test Node's npm); that failure is pre-existing on 483eccb3d, so the lead committed. Sol review APPROVE 0 (word-for-word diff against draft 2, catalog order, both requirements tests). Defect l: before, an agent that declared a store credential made the next bus start refuse, because Credentials refuses a missing store root and only issue() created it. After: start creates the root 0700 when any reference names the store; a root that exists with loose modes or as a symlink still refuses. Two new credential-verbs tests fail on the parent. Bus suite 171 files one at a time, 1713/0 (Node 26.12.1, env -i). Sol review APPROVE 0. uiorg redeployed at 7a97cfc4f, 23:15Z. Follow-up: the stack-copy node-gyp test environment.
