fix(organization): address accounts review and rollback edge cases (#1873)

A conflict on a task another writer moved out of the board's server
filter now reads that task from its organization unfiltered, so the
dialog reopens on the current task. An empty result names the
organizations whose tasks were not read instead of saying there are
no tasks.

 2026-11-09 UTC | Unified workspace (#1873) — direction recorded | Before: the 11-07 rulings had one Console switch between organizations from Settings, tasks only in each org queue, and an agent bound to one organization (REQ-USER-1). After: Jason's 11-09 direction and answers recorded in docs/plans/2026-11-09_unified-workspace-owner-direction.md (all orgs visible at once, per-org task stores with a Vikunja option and an aggregated Kanban, root/org/project agents with one cross-org assistant, system type plug-ins, self-service restart and model switch). PRD 1.20 draft 1 written for his exact-text approval; the PRD itself is unchanged. The unpushed 11-07 rulings record (ad8140065) lands with it.

+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. Reports: /mnt/storage/scratch/mosaic-lead/reports/org-{reqget-2,f1,rename-b,f2,u0-design,e2e5}-*.md.
+
+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. Report: /mnt/storage/scratch/mosaic-lead/reports/org-f3-review.md.

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.

+2026-11-10 UTC, unified workspace U1 and SYS1 (#1873; PRs #1889 d35447005 and #1890 2c6556ab1). U1, before: each org page read only its own bus and nothing read every org at once. After: /api/workspace returns projects, sessions, inbox, tasks and metrics from every org the owner holds, each row tagged with its org and each org with a state (ok, starting, down, timeout, invalid); `mosaic console restart` and `mosaic org reload <org>` send the F3 routes. Sol review CHANGES 0/2 on 2109458b3: malformed data from one org turned the whole read into a 503, and the per-org deadline left sockets and transport children running. Terra fix 0672d5fe8 validates each org's result inside its boundary and carries an absolute deadline and AbortSignal through the status check and transport; the new workspace-failures test is 0/10 on the parent and 10/0 on the fix. The lead re-pinned the webui bus.mjs hash in bus channel-proof (the deliberate signal/deadline change; nonces, argv and limits unchanged) and amended as d35447005. SYS1, before: no system-type kind. After: a system-type plug-in kind with five modules (business-management, coding, creative-writing, marketing, montage), an org enable list under plugins.system-type, owner-only project selection with an append-only project_system_types table (migration 3t-3u) and CLI verbs; the modules grant no tools yet (REQ-SYS-2 deferred). Sol review CHANGES 1/2 on a9629f332: the restore guard did not count project_system_types, the CLI channel did not admit the two project verbs, and the #811 migration-reader pin still expected 18 steps. Lead fix 2c6556ab1 (rebased on d35447005) adds the table to COUNTED and LISTED with refusal and in-run recount tests, admits both verbs with a run()-level channel test (red on the unfixed channel), and moves the pin to 19 steps ending 3t-3u; fix files 323/0 and rebase overlap files 63/0 (Node 26.12.1, one file at a time, env -i). Full gate on a9629f332 4040/5: the two stack-release pins above, and tester-reads 3/3, which also fails on 1616d1dd6 (project.mjs:95 refuses an org --tester init; follow-up). Correction to the uiorg deploy at 00:50Z: the deploy script switched the tree without the offline schema migration, so all five buses refused to start (normal startup refuses an older schema by design). The lead ran migrate-schema.mjs for the five org stores (3t to 3u, all ready), restarted the buses (201 each) and added the migration to the deploy script with stop-on-refusal. test3 refused writer-locked and stays down, as before.

 `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.

 The instance processing switch is separate from per-business launches off/on.
 `mosaic halt` durably stops managed processing across every business in the
 selected configuration's data root. The bus stays up for reads and human

+# Agent levels and the cross-organization assistant (Phase A design, #1873)
+
+Status: design for lane org-a1, 2026-11-10. Slice A1 (read-only store, union
+resolution, Agents grid) is built on branch `org-a1`. Everything that gives an
+agent a new capability is in the roles proposal and the later slices listed in
+section 9; none of it is applied.
+
+Direction: PRD 1.20 draft 2 (REQ-ASSIST-1, REQ-USER-1 amendment, REQ-AGENT-1
+to REQ-AGENT-3, REQ-COS-3, REQ-DEC-2, REQ-ROLE-3), owner direction rulings 4
+and 11, the U0 approval and the addendum in
+`docs/plans/2026-11-09_unified-workspace-owner-direction.md`, and the role model
+in `roles/` and `docs/plans/2026-09-02_atomic-mosaic-foundation.md`.
+
+Owner words: "Agents are configured at three levels: the user's root, the
+organization and the project. A project's agents are the union of all three.
+The user's main interaction agent (the assistant) is the one exception to
+isolation. [...] Every other agent is isolated to the organization it works
+in." And: "the COS should be able to hire and fire agents to fulfill the
+user's needs."
+
+## 1. Terms
+
+- **Definition**: a named agent entry at one level. It names a role
+  definition in `roles/` (`definition`) and may carry vars. It never names a
+  credential, a holder, a tracker bot, an identity or a publish grant at the
+  root or project level.
+- **Role definition**: `roles/<name>.json`, versioned and changed only by
+  reviewed commits (invariant 7). A level chooses among role definitions and
+  never creates one, so no level can grant an authority that `roles/` does
+  not already hold.
+- **Copy**: a root definition as it runs inside one organization. Each
+  organization runs its own copy, and each copy has that organization's
+  memory, files and credentials.
+- **Union**: the agents available in one project of one organization.
+
+## 2. Where each level lives
+
+| Level | File | Writer today | Owner |
+|---|---|---|---|
+| root | `<configDir>/agents.json`, next to the instance's system config | the user, by hand (no writer in A1) | the instance's OS user |
+| org | `roles` in `<configDir>/businesses/<org>.json` (unchanged) | existing org writers | the organization |
+| project | `projects.<project>.agents` in the same organization file | the owner's `updateOrg` only; no agent writer can reach it | the organization |
+
+### Root: `<configDir>/agents.json`
+
+`configDir` is the directory of the instance's system config
+(`~/.config/mosaic-<instance>/`). The file sits outside the data root, so it is
+outside every organization root (`<dataRoot>/org-runtime/<org>`) and every
+bus, and no bus or sandbox mount reaches it. It is per instance, as the system
+config is (invariant 2). When accounts arrive (Phase M), it moves to a
+per-principal path under the same directory; the format stays.
+
+```json
+{
+  "agentsVersion": 1,
+  "agents": {
+    "assistant":  { "definition": "assistant", "vars": { "model": "opus-5.5" } },
+    "reviewer":   { "definition": "reviewer", "excludeOrgs": ["home"] },
+    "researcher": { "definition": "researcher" }
+  }
+}
+```
+
+- Keys: `definition` (required), `vars` (agent layer, `checkVars(..., "agent")`),
+  `excludeOrgs` (distinct organization ids; "reviewer turned off for Home" in
+  sample 08). Any other key refuses.
+- The file must be a regular file opened without following a link, owned by
+  the process uid and not writable by group or other, the same checks as the
+  organization file. A missing file means no root agents. Anything else that
+  is wrong refuses the whole root level (section 6).
+- Refused at the root: a role definition that is version 1 or missing, the
+  `chief-of-staff` definition (each organization's chief is its own,
+  REQ-COS-3), an `assistant` definition under any name but `assistant`, and
+  `credentials`, `holder`, `tracker`, `identity`, `publish`, `hosts`.
+
+### Organization: `roles`
+
+Unchanged. Every organization instance stays as it is, validated by
+`validateBusinessDocument`, with its credential map, tracker bot and identity.
+
+### Project: `projects.<project>.agents`
+
+The project level is in the organization file, not in the project repository.
+The repository's `.mosaic/project.json` can be written by any agent that can
+push to the project, so a definition there would let an agent create agents.
+The organization file is reachable only by the trusted writer, and the
+existing projects fence (`organization-projects-protected` in
+`organization.mjs`) already refuses every general write that changes
+`projects`. No agent writer can add, change or remove a project agent. The
+owner's `updateOrg` can, and the Console's organization editor holds the key
+on the server (`SERVER_PROJECT_KEYS`), so the browser draft cannot change it in
+A1.
+
+```json
+"projects": {
+  "spring-launch": {
+    "root": "...",
+    "agents": {
+      "social-scheduler": { "definition": "pm", "vars": { "model": "haiku-5.5" } },
+      "coder":    { "vars": { "limits.network": "none" } },
+      "reviewer": { "exclude": true }
+    }
+  }
+}
+```
+
+Each entry has exactly one form:
+
+- **define**: `{ "definition", "vars"? }`. Agent-layer vars. Not
+  `chief-of-staff`, not `assistant`.
+- **narrow**: `{ "vars" }` only. Every key must be an intersect key
+  (`limits.tools`, `limits.network`, `limits.authority`), checked at the
+  project layer. A project narrows an inherited agent and never widens it.
+- **exclude**: `{ "exclude": true }`. The inherited agent is not available in
+  this project.
+
+`validateBusinessDocument` checks each entry's shape and role definition for
+every reader (bus, Console, CLI). It does not copy `agents` into the loaded
+business object, so a bus built from the file sees exactly what it saw before.
+A project that is deleted takes its agents with it, and so does a deleted
+organization.
+
+Library projects (`kind: "library"`) keep their own mapping check and take no
+`agents` key.
+
+This is an additive, optional key in the organization file. It is not a bus
+store (SQLite) schema change: no migration, no new table, no bus verb.
+
+## 3. Union resolution
+
+For organization O and project P:
+
+1. Start with the root agents, minus any whose `excludeOrgs` names O.
+2. Lay the organization's `roles` over them. An org instance with the same
+   name as a root agent replaces it entirely; the root entry is recorded as an
+   override of that agent.
+3. Lay P's entries over the result:
+   - **define** replaces any inherited agent of that name; the inherited
+     entry is recorded as an override.
+   - **narrow** merges vars through `mergeVars`, inherited layer first and the
+     project layer after it, so limits only intersect. The keys it narrowed
+     are recorded.
+   - **exclude** removes the agent and records who removed it.
+
+Rules:
+
+- The most specific level that defines a name wins, and the whole entry
+  wins: definition and vars, never a field-by-field mix.
+- A narrow or exclude entry naming an agent that no lower level provides
+  refuses. A typo never silently does nothing.
+- A project entry of any form naming the organization's chief (an instance
+  whose definition is `chief-of-staff`) or the assistant refuses. A project
+  cannot remove, narrow or replace the chief or the assistant.
+- Two levels never merge vars, apart from a project narrowing. Root vars stay
+  with the root definition, and an org instance of the same name brings its
+  own.
+- The result for each agent: name, definition, level, source (which file),
+  the overrides it shadows, the keys narrowed, and its scope. Every agent in a
+  union is scoped to O, an organization's own `assistant` instance included.
+  Only the root assistant, which no union holds, is cross-organization.
+- The union also lists what O or P does not get: root agents turned off for
+  O and agents P excluded. A name that a more specific level then defines is
+  available under that definition and is not listed.
+
+Implementation: `packages/organization/src/agent-levels.mjs`
+(`loadRootAgents`, `checkRootAgents`, `checkProjectAgents`,
+`resolveAgentLevels`, `projectUnion`). It is pure apart from the one root file
+read.
+
+## 4. Isolation of every non-assistant agent
+
+Every agent except the root assistant resolves to scope `{ org: O }` in the
+organization it runs in, whichever level defined it. The scope fixes three
+things:
+
+- **Memory and records**: under the organization's root,
+  `<dataRoot>/org-runtime/O/...`, on that organization's bus, as every org
+  instance has today. A root agent's copy in O and its copy in O2 share
+  nothing: no thread, no record, no session file.
+- **Files**: the project workspaces of O only. The sandbox mounts come from
+  O's project mapping, never from another organization's.
+- **Credentials**: only from O's credential map. A root definition carries
+  none (refused, section 2). In A1 a root or project agent is shown as
+  unbound: it has no credential and cannot be launched, because the bus
+  builds instances from `roles` alone and the loaded business object does not
+  carry project agents.
+
+When root copies run (slice A3), each copy becomes a bus instance in O under
+O's writer, with O's credential bindings, through the same `checkRoles` path an
+org instance takes. A copy never reads the root file at run time; it gets its
+definition when O's bus boots.
+
+## 5. The assistant across organizations
+
+### Reads
+
+The assistant reads another organization only through the Console's
+membership-checked cross-organization read: `organizations.members(session)`
+(`packages/webui/src/organizations.mjs`), the read `GET /api/workspace` uses.
+Each organization is admitted by `showOrg` (owner check, registry digest,
+document validation) and `resolveOrg` (marker, modes) before any transport is
+built, and each bus read goes over that organization's own socket with a
+deadline. The assistant process gets no org root path, no bus socket path and
+no file mount of any organization. It calls a read broker that the Console
+holds for the owner's session. A direct read of another organization's bus
+files does not exist as a code path: the assistant sandbox mounts only its own
+memory directory.
+
+### Shared memory
+
+The assistant's one memory lives at `<dataRoot>/assistant/` (mode 0700, owned
+by the instance user). It sits inside the instance data root and outside every
+`org-runtime/<org>` root, so deleting or archiving an organization never
+touches it, and no organization's agents can mount it. It holds the
+assistant's notes and session files. It never holds a copy of an
+organization's records; what the assistant learns from an organization stays
+in that organization, plus whatever the assistant chose to write in its own
+memory.
+
+### Authority
+
+REQ-ASSIST-1: the assistant talks with the user and hands each organization's
+work to that organization's chief. It does not direct agents, create tasks or
+launch sessions. Its role keeps `message.send` and `record.write` only. The
+roles proposal (section 8) adds no action to it.
+
+### A1 reality
+
+Today each organization file declares its own `assistant` instance. A1 shows
+those as org agents. A root `assistant` entry, if the user writes one, shows in
+the band as the root assistant with cross-organization scope. Nothing reads
+across organizations for it yet.
+
+## 6. Fail-closed boundaries
+
+| Boundary | A1 behavior | Later slices |
+|---|---|---|
+| Root file (new) | `O_NOFOLLOW` regular file, process uid, no group or other write; any problem refuses the whole root level and the grid says so; a missing file is "no root agents". The refusal names the file and the key at fault, never a value from the file: parser text and a var check's quote of the refused value are dropped, since a value can be a secret typed in the wrong place. Project var refusals drop the value the same way. | The root writer accepts only the human session (section 7). |
+| Organization file `projects.<p>.agents` (new key) | Checked by `validateBusinessDocument` for every reader; a bad entry refuses the whole organization file, as any bad key does. Not copied into the loaded business, so buses gain nothing. The projects fence keeps every agent writer out. | A project-agent writer verb, with its own guard, like `addProject`. |
+| Union | A narrow or exclude naming nothing refuses that project; touching the chief or assistant refuses that project; the grid shows the refusal for that project. | A launch resolver refuses to launch any agent in a project whose union refuses. |
+| Console read `GET /api/agents/levels` (new) | Owner only (granted users and the tester get `owner-only`, 403); organizations come only from `organizations.members(session)`; the body carries ids, names, role definition names, model var and level. It never carries a path, a credential reference or a var other than `model` and the narrowed key names. | Unchanged. |
+| Org isolation | Root and project agents are not instances on any bus; nothing reads across organizations except the existing Console read. | Each copy is materialized by O's own writer and runs under O's credentials. |
+| Assistant memory | Not built. | `<dataRoot>/assistant/` with 0700; the sandbox mounts it and nothing else. |
+| Roles | No change in commits. | The proposal patch, applied only after Jason approves it. |
+
+A root file that refuses hides the root level everywhere rather than showing a
+partial list: an exclusion that did not parse must not let an excluded agent
+appear.
+
+## 7. Chief-of-staff hire and fire, per level
+
+Today `roles/chief-of-staff.json` lists `role.hire` and `role.fire` within its
+role, with `"hireable": []`: it can hire nothing. Each level adds a write path;
+none exists in A1.
+
+- **Organization level** (REQ-COS-3): the chief hires or fires an
+  organization instance through the organization's trusted writer, for a role
+  in its `hireable` list. Each hire lands in the action trail. The user can
+  override any setting at any time through REQ-ROLE-3.
+- **Project level**: the chief adds or removes a project entry through a new
+  writer verb that changes only `projects.<p>.agents` (a guard like
+  `addProject`'s), for a role in `hireable`. The projects fence still refuses
+  every other change.
+- **Root level** (U0 ruling): the chief cannot write the root file. It raises
+  an inbox decision (REQ-DEC-2) in its own organization that names the role
+  definition, the agent name and the reason. The user approves or denies it in
+  the Console inbox. On approval the Console, acting with the human's session,
+  writes the root file through a root writer that refuses any actor other than
+  the signed-in owner (`human-required`). A denied or expired decision changes
+  nothing. A fire works the same way. The chief never learns the file's path.
+
+`hireable` decides what can be hired at all; widening it is a `roles/` change
+and needs Jason's reviewed commit. The proposal (section 8) names the roles.
+
+## 8. Authority changes proposed, not applied
+
+The patch is at `/mnt/storage/scratch/mosaic-lead/reports/org-a1-roles-proposal.patch`.
+It is never applied on this branch. It applies with `git apply` on
+`origin/refactor` and needs a reviewed commit that Jason approves.
+
+What it changes:
+
+- `roles/chief-of-staff.json`: `hireable` goes from `[]` to `coder` and the
+  five advisory chiefs (`chief-executive-officer`, `chief-financial-officer`,
+  `chief-information-officer`, `chief-information-security-officer`,
+  `chief-marketing-officer`). These are the only shipped definitions that pass
+  today's hire check: version 2, not creative, and every action on
+  `HIRE_ALLOWED`. The chief can then hire at the organization level with the
+  existing `hire` verb. The project level (A4) uses the same list.
+- `roles/chief-of-staff.md`: drops "your empty hireable list", names the list,
+  says a hired coder has no credential until the human binds one, and says the
+  chief hires only in its own organization, never at the root.
+- `packages/organization/tests/chief-of-staff.test.mjs` and `role.test.mjs`:
+  the tests that pin the shipped chief file move to the new list, and the
+  contract test pins the new sentence. Two bus test comments that said "shipped chief hireable:[]" are
+  reworded. These go in the same commit, or the organization suite fails.
+
+What it leaves alone, and why:
+
+- `roles/assistant.json`: no change. The cross-organization read is the
+  Console's read broker acting for the owner's session (section 5), not a
+  role action, so the assistant needs no new grant. It keeps `message.send`
+  and `record.write`. Adding an action would widen it for no gain.
+- `roles/assistant.md`: no change yet. Its "one user in one business" text
+  stays true until A6 builds the root assistant; the contract text for the
+  cross-organization read and the shared memory lands with A6, in that
+  slice's own reviewed commit.
+- Root-level hire text in `chief-of-staff.md` lands with A5, when the inbox
+  decision exists. A contract sentence for a tool the chief doesn't have would
+  invite it to try.
+- `HIRE_ALLOWED`: unchanged. `reviewer`, `security-reviewer` (`review.verdict`),
+  `pm` (`task.create`), `cto` and `merge-gate` stay unhireable. Making any of
+  them hireable is a separate vocabulary decision, not part of this proposal.
+
+## 9. Phase A slices after the roles change is approved
+
+1. **A2, root and project writers.** Owner-only root file writer (human
+   session, trail entry, revision check) and the project-agent writer verb
+   under the projects fence, both refusing every agent actor. Settings,
+   Agents gets the edit forms.
+2. **A3, root copies run.** Each organization's bus boot materializes its
+   root copies as instances through `checkRoles`, with the organization's
+   credential bindings; unbound copies stay unlaunchable and say why. Project
+   agents launch only in their project.
+3. **A4, chief hire and fire at org and project level**, bounded by the
+   approved `hireable` list, trailed.
+4. **A5, root-level hire and fire as inbox decisions**, with the owner's
+   approval writing the root file through A2's writer.
+5. **A6, the root assistant.** `<dataRoot>/assistant/` memory, the Console
+   read broker over `organizations.members`, and the per-organization
+   `assistant` instances retired in favor of the one root assistant.
+6. **A7, the Agents grid's write controls** (model Change, override markers,
+   turn off for an organization), each a trailed human action.
+
+## 10. Slice A1 as built
+
+- **Store and union**: `packages/organization/src/agent-levels.mjs`, with the
+  old-path re-export `packages/business/src/agent-levels.mjs` that the rename
+  r2 stage B test requires of every organization module.
+  `validateBusinessDocument` checks `projects.<p>.agents` and drops it from
+  the loaded business.
+- **Read**: `GET /api/agents/levels` (`packages/webui/src/agent-levels-read.mjs`),
+  wired in `cli.mjs` with `loadRoot` reading `<configDir>/agents.json`. The
+  route is instance-wide, like `/api/workspace`, so `display.js` leaves it
+  unscoped: its fetch wrapper would otherwise rewrite it to
+  `/api/orgs/<id>/agents/levels`, which does not exist.
+- **Console editor**: `SERVER_PROJECT_KEYS` holds `agents`, so a browser draft
+  of the organization file keeps the server's value. The CLI's full-document
+  path (`mosaic org update --from`) is the owner's and can set project agents;
+  A1 adds no other writer.
+- **Agents grid** (sample 08): the level band shows the root agents and their
+  per-organization opt-outs, each organization's instances, and each
+  project's own definitions. Below it, a project picker chooses which union
+  the table shows: agent, level, defined in, memory, status, model. Root and
+  project agents read "not running", because nothing launches them yet. The
+  root assistant's status reads "status not reported" and its model is the
+  one the root file sets, shown as configured. A
+  narrowed agent names the keys, an override names what it replaces, and a
+  line under the table lists what this project does not get and why. A
+  refused root file, organization or project shows its reason in place of
+  its rows. The grid has no write controls; those are A7.

+System types are installed plug-ins. `mosaic org system-types installed` prints
+module metadata; `mosaic org system-types enabled ID` prints an organization's enabled
+ids. The owner changes the enabled list through the existing organization file
+update or `mosaic plugins set`. `mosaic project system-types PROJECT --org ID`
+shows selected, active and inactive ids. The owner replaces the selection with
+`mosaic project system-types-set PROJECT --types coding,montage --org ID`; an
+empty `--types ''` clears it. Disabled selections stay recorded but become
+inactive. Project settings changes are append-only and require human proof.
+
+## Accounts
+
+`mosaic accounts` administers the instance-level accounts store locally, as the
+effective uid owning the config directory. It requires a human shell, rejects `--tester`,
+and takes no business selector or bus connection. It has no organization rights
+verbs. Console sign-in, sessions and membership evaluation are later Phase M
+slices; these commands alone do not turn accounts mode on.
+
+```sh
+mosaic accounts init --name Operator
+mosaic accounts list --json
+mosaic accounts user add --name Pat --subject pocket:verified-subject --revision 1
+mosaic accounts user disable u-0123456789ab --revision 2
+mosaic accounts user enable u-0123456789ab --revision 3
+mosaic accounts user signout u-0123456789ab --revision 4
+mosaic accounts user remove u-0123456789ab --revision 5
+```
+
+Init creates one operator account containing every configured `console.sso`
+subject and refuses if accounts.json already exists. Add mints its id and defaults
+to instance role `user`; `--role operator` creates another operator. Writes require
+the file revision from list. Disable, enable and signout advance `authGen`, and
+the last active operator cannot be disabled or removed. Removal scans ownership
+while holding the registry then accounts locks, refuses if the account owns an
+organization (including archived organizations) or any registry entry lacks its
+owner metadata during creation, and removes its memberships in
+the same write. List reports rollback rows needing repair; its JSON omits invite
+bindings and hashes. Receipts record effective process uid and verb and omit subjects and secrets.

 selection on this release's throwaway development instances. Receipt subjects
 name that principal, not Jason. The dev-purpose bootstrap fence is a separate
 follow-up before person-used deployment.
+
+The optional `plugins.system-type` list enables installed system-type modules for
+an organization. Missing means none. Unknown ids refuse validation. Changes
+are owner-only; project selections are separate bus settings and a selection
+whose type is disabled remains recorded as inactive.
+
+## Instance accounts (Phase M2)
+
+`src/accounts.mjs` validates `<configDir>/accounts.json` without a dependency or
+JSON schema engine, as `access.mjs` does. `checkAccounts(document, {providers})`
+and `loadAccounts(file, {providers})` return frozen documents. Providers are the
+configured `console.sso.providers` objects (including issuer). Reads refuse an
+unsafe config directory, unsafe file, unknown field or malformed row. Account
+ids may be organization humans. `accountsRepairs(document)` reports unknown
+roles and rights retained on read for rollback; these rows must grant nothing.
+M4 supplies the authorization evaluator; M2 alone grants no Console or bus access.
+
+`withAccounts(ctx, {revision, verb, actor?, registry?, init?}, mutate)` takes
+`accounts.lock`, reloads, checks the expected file revision, awaits `mutate` on a
+copy, maintains `authGen` and membership `rev`, validates and atomically replaces
+0600 bytes. Init publishes with a no-clobber hard link; replacements use rename.
+Both fsync the config directory before the receipt is appended. `ctx` contains `configDir`, `instance`, and `providers`. Init requires
+revision 0 and an absent file. Other writes require an existing valid file. Writes
+refuse unknown rights/roles on new or changed rows. Unchanged rollback rows pass
+through exactly, so they cannot block account revocation or another row's repair. Role templates are never evaluated as authority by this store.
+
+For a caller already holding accounts.lock,
+`withAccountsLock(ctx, handle => withAccountsLocked(handle, options, mutate))`
+reuses that live opaque handle. Never acquire an earlier lock from the callback.
+The config path must have no symlink ancestors, including the home directory.
+The order is lifecycle, registry, accounts. Registry-dependent writes pass the
+live document from `withRegistry`; `readRegistryLocked(registry, ctx?)` verifies
+the lock and rereads its persisted snapshot without relocking. A changed registry
+or an instance mismatch refuses before account publication. Callbacks cannot
+reuse a released handle, or run two writes at once through one handle.
+
+Each committed write appends and fsyncs one receipt under the accounts lock in
+`accounts-receipts.jsonl`: effective OS uid, actor id, verb, old/new file revisions, changed
+account ids with changed field names, and before/after membership rights, scope
+and revisions. No account
+name, subject, invite binding, hash, raw token or cookie enters the receipt. The
+store preflights the receipt destination before replacing accounts. As with
+other two-file journals, a crash or IO failure between replacement and receipt
+append can leave committed state without its receipt; an observed append failure
+has `committed: true` and must be inspected before retrying. It never rolls back
+committed authority silently or fabricates a success receipt.
