+# Row 238: the sso-config hint names the instance (row 200 follow-up N1)
+
+Launchpad, 2026-10-21. Author Launchpad, reviewer Webby, gate owner Sage. Issue #1744. Brief "Brief: row 200
+follow-up N1, the sso-config hint names the instance" in `docs/plans/2026-10-20_stack-release-sso.md` (76134dfde),
+from Webby's row 200 round 3 note N1 (comment 29772), assigned in sage-1597.
+
+Base 011d41ba6 (`base.txt`), which has row 200's landing 9e1085816 below it. Built on 76134dfde, then rebased
+before the first push onto 011d41ba6, because row 199 (cb5fdb064) added 6 lines to `docs/TOOLS.md`; no
+conflict. Branch `launchpad/row238`.
+`candidate-manifest.sha256` lists the 3 changed paths; the packet files are not in it.
+
+No test touches `~/.mosaic-dev`, `~/.config/mosaic-dev`, `~/.mosaic`, a live unit or a live slot. The new
+subtest runs on row 190's `named()` scratch instance under the test's temp HOME.
+
+## Files
+
+| Path | Change |
+| --- | --- |
+| `scripts/stack-release.sh` | `sso_checks`: the N4 first step puts `${INSTANCE_FLAGS[*]}` after `activate $TO` in both commands. |
+| `packages/cli/tests/stack-release.test.mjs` | T57 subtest "row 238 (#1744)": the sso-config refusal and the `--plan` line on instance `alpha`. |
+| `docs/TOOLS.md` | The `sso-config` paragraph says both commands carry `--instance NAME` on a named instance. |
+
+## What it does
+
+On a named instance the hint now reads `activate ID --instance NAME without --sso first, then write
+console.sso, then run activate ID --instance NAME --sso`. `INSTANCE_FLAGS` is empty for the default instance,
+so `inst` is empty and the default text is unchanged byte for byte. T57's item 2 subtest still asserts the
+default text exactly. The flag goes right after `ID`, the same place the other entry points take it from
+`INSTANCE_FLAGS`. BUSINESS is not in the hint before or after this row.
+
+## Tests run (this tree)
+
+- `node --test tests/stack-release.test.mjs`, the whole file: 193/193 on 76134dfde
+  (`/mnt/storage/scratch/launchpad-r238/sr-whole.log`) and 193/193 again after the rebase onto 011d41ba6
+  (`sr-whole-2.log`), with the new subtest and T57's default-text check.
+- `tests/stack-instances.test.mjs`, whole: 23/23 (`si.log`). It names `stack-release` only in a comment.
+- A grep of `packages/*/tests/` and `scripts/test-*.sh` finds the hint text only in `stack-release.test.mjs`
+  (`:1951` default, `:2102` and `:2104` named) and no 64-hex pin on the 3 paths.
+- The cli suite, every `scripts/test-*.sh` and the mutant go to Sage's slot.
+
+## Mutants (`mutants.py`, run as `python3 mutants.py <tree> [N ...]`, against T57)
+
+| # | Mutant | Result |
+| --- | --- | --- |
+| 1 | the first step drops `--instance NAME` (`inst=""`) | not run, Sage's slot |
+

-# Row 237: one decision publishes once (#1743)
-
-Megavolt, 2026-10-21 (from `date -u`). Brief: `docs/plans/2026-10-20_agent-credentials.md`
-§ "row 199 follow-up N1", blob dca67d310e1b. Source: Duckworth's row 199 round 1 note N1
-(duckworth-0068). Base: `cb5fdb064` (row 199's landing). Reviewer Duckworth, gate owner Sage.
-
-## The defect
-
-`checkPublish` opens a ticket after checking the decision is unspent. The decision is spent only at
-`recordPublish`, which runs after the bus process has pushed. Two `checkPublish` calls on one decision
-therefore both get tickets, and both push. With different branches, the commit lands on two fork refs:
-`refs/heads/<user>/feat` and `refs/heads/<user>/other`. The second `recordPublish` then refuses
-`decision-consumed`, but by then its push has already reached the fork.
-
-## The fix, and why this option
-
-`checkPublish` refuses `publish-busy` when an open ticket in `#publishes` holds the same business and
-decision (`packages/bus/src/broker.mjs:1038-1040`). It runs after the authority and fact checks, so a
-spent decision still refuses `decision-consumed` first.
-
-The brief's other option, rechecking `#spent` in `publishTarget`, doesn't close the race. Both tickets
-reach `publishTarget` before either push ends, and nothing is spent until `recordPublish`. So both
-rechecks pass and both pushes run. The only state that exists while the first push runs is the open
-ticket, so the check reads that.
-
-A refusal (`publishRefused`) drops the ticket and leaves the decision unspent, so a retry on the same
-decision gets a new ticket. That is row 199's behaviour, unchanged. A within-role publish has no
-decision and isn't affected.
-
-## Tests
-
- `packages/bus/tests/publish.test.mjs:186`. A second ticket refuses `publish-busy`, on the same branch
-  and on another. After `publishRefused` the retry gets a ticket and a third refuses busy. After
-  `recordPublish` there is one `action.allowed` for git.push.remote and the next call refuses
-  `decision-consumed`. Another agent's decision on the same task isn't held.
- `packages/cli/tests/publish-socket.test.mjs:269`. End to end through the git socket, the bus runtime
-  and the TLS fake Gitea. While the first publish holds its ticket, a second publish on the same
-  decision to branch `other` gets `publish-busy`. The fake Gitea gets exactly one `git-receive-pack`,
-  the fork has only `refs/heads/coder/feat`, and there is one `action.allowed`.
-
-Runs on this branch, single files:
- publish.test.mjs: 13/13.
- publish-socket.test.mjs: 8/8.
-
-## Mutant
-
-M1 removes the `publish-busy` line. Both tests fail:
- The bus test fails at the first busy assert.
- The cli test fails because the second publish answers `ok: true` with `ref: refs/heads/coder/other`.
-  That is the defect: two refs on the fork.
-
-Logs are in `/mnt/storage/scratch/megavolt-r237/` (m1-bus.log, m1b-cli.log). `cmp` confirmed
-broker.mjs matched the saved copy after the restore. The first cli mutant run (m1-cli.log) was against
-a hook that recursed on every checkPublish. I fixed the hook to fire only for branch `feat` and reran
-it (m1b-cli.log).
-
-## Residuals, not fixed here
-
-1. **A ticket that never ends holds its decision until the bus restarts.** `#publishes` is in memory.
-   That happens when the host dies between checkPublish and recordPublish or publishRefused. It fails
-   closed (`publish-busy`), and a restart clears it.
-2. **publish-timeout (sage-1440).** The socket files `publishRefused` and drops the ticket, but the bus
-   process's push may still be running. A retry on the same decision can then open a ticket while that
-   push is live. This is the same residual the socket already logs ("the bus process's push may still
-   reach the fork"). Closing it means the runtime's `remotes` must keep the decision busy until its push
-   settles, which reaches into runtime.mjs. That is beyond the brief's two options.
-3. **checkLand has the same shape.** `#landings` takes a ticket per call and the decision is spent at
-   `recordLand`. Whether two landings on one decision can both reach main isn't checked here. That's a
-   follow-up for Sage to row or dismiss.
-
-## Gate
-
-Per the brief: Duckworth approves the manifest, the bus suite and every `scripts/test-*.sh` are green
-on Sage's gate, and M1 is killed. This row also changes a cli test file, so the cli suite (or that file
-alone) should run on the gate too.

-follow-up N1, a retry after publish-timeout pushes once" (9d165be8c). Base: origin/refactor
-8fede5fc6 (row 210 landed f5753c0e8).
-
-## The defect
-
-The git socket polls publishResult until publishDeadlineMs, then refuses publish-timeout
-(packages/cli/src/git-socket.mjs:433) while the bus process's push (runtime publishPush) can
-still be running. The socket then calls publishRefused, which went straight to
-broker.publishRefused: it filed the refusal and deleted the ticket. checkPublish no longer saw an
-open ticket on the decision, so a retry got a new ticket and pushed a second ref while the first
-push was still on its way to the fork.
-
-## Fix chosen: hold the decision until the push ends, then record a push that reached the fork
-
-packages/bus/src/runtime.mjs, `publishRefused` and `settle`:
-
- If the bus has no push for the ticket, publishRefused goes to the broker as before.
- If the push is still running, the refusal code is held on the entry and the ticket stays open.
-  checkPublish refuses another publish on the decision with publish-busy (row 237's check),
-  the same as when the socket is still polling.
- When the push ends, `settle` runs:
-  - A push that reached the fork is recorded with broker.recordPublish, which spends the
-    decision. The bus logs `pushed after the git socket refused <code>; recorded`.
-  - A push that failed is filed as publishRefused with the socket's code.
-  - If recordPublish refuses with a BusError, that code is filed instead.
- If the push has already ended when the refusal arrives, it's settled at once. The sage-1440 test
-  relies on this: its push fails fast, so publish-timeout is filed once, immediately, as before.
-
-Why hold rather than kill. Killing the git client doesn't undo a push the fork has already
-received: receive-pack can update the ref after the client dies. After a kill the bus would have
-to ls-remote the fork to learn what landed, and the result could still race the server. Holding
-waits for the push's own outcome. Each git run in publishRemote already has its own limit
-(publishRemote defaults to checkout.mjs GIT_LIMITS), so a hold is bounded. Holding also reuses the existing publish-busy
-state, and the refusal text is unchanged.
-
-Why record and not only hold. If the hold just filed publish-timeout once the push ended, the
-ticket would close and the decision would be free again with a ref on the fork. A retry would then
-push a second ref. Recording the late push spends the decision, so the retry gets
-decision-consumed.
-
-The publish-timeout refusal text is unchanged (brief condition).
-
-## Test
-
-packages/cli/tests/publish-socket.test.mjs:302, "row 242: a retry after publish-timeout refuses
-publish-busy while the bus process's push runs; the late push is recorded and the decision pushes
-once".
-
- publishDeadlineMs 150 and a store token. The fork's pre-receive hook writes `held`, then loops
-  until the test writes `release`.
- The first publish gives publish-timeout. The test waits for `held`.
- A retry to branch `other` gives publish-busy (:322). Refused events: ["publish-busy"]. No
-  git.push.remote allowed event.
- The test writes `release` and waits until there is exactly one allowed event, with ref
-  refs/heads/coder/feat and the work commit.
- The next retry gives decision-consumed (:330).
- Exactly one git-receive-pack request reached the fake Gitea, and the fork has only
-  refs/heads/coder/feat. Refused events: ["publish-busy", "decision-consumed"]. No TOKEN appears in
-  events or logs.
-
-Fail fast (sage-1681): the body is wrapped in try/finally, and the finally writes `release`. Under
-the first mutant run, the assert at the retry failed and the hook was never released. setup's
-teardown waits for the fake Gitea, which waited for the held push, so the file hung until I stopped
-it. Now a failed assert ends the hook and the run. Each wait is bounded at 10 s with an assert.fail.
-
-## Mutants
-
-Script: /mnt/storage/scratch/megavolt-r242/mutants.sh. Each mutant: save, one-line sed, run
-publish-socket.test.mjs whole, restore, cmp.
-
-| Mutant | Change | Expected kill |
-|---|---|---|
-| M1 | export `publishRefused: (ticket, args) => broker.publishRefused(ticket, args)` again (removes the fix) | :302 at :322: the retry gets a new ticket and its own push, so publish-timeout, not publish-busy (seen in the stopped 03:06Z run) |
-| M2 | `settle` files publishRefused without trying recordPublish (hold only) | :302 at the wait for one allowed event, then :330 |
-
-Results (Sage's slot, sage-1686, 2026-10-21T03:35:00Z to 03:35:15Z): both killed, both restored
-(cmp ok).
-
- M1: publish-socket 8/1, the row 242 test fails at :322 in 0.5 s.
- M2: publish-socket 8/1, the row 242 test fails at :327 (the bounded wait at :311 for one allowed
-  event) in 10.3 s.
-
-## Suites
-
-On Sage's slot (sage-1686), on base 8fede5fc6 plus this row:
-
- bus `node --test tests/*.test.mjs`: 499/499, 03:35:20Z to 03:35:34Z. This is one fewer than
-  Sage's 241 gate (500) because the base predates row 241's land.test case.
- cli `node --test tests/*.test.mjs`: 566/566, 03:35:34Z to 03:43:47Z. That's 565 plus the
-  row 242 test.
-
-Singles before the slot: publish-socket.test.mjs 9/9, bus publish.test.mjs 13/13. The seat suite
-and scripts/test-*.sh are left for Sage's landing gate.
-
-## Residuals
-
- The agent was told publish-timeout, but the push is recorded later and the run isn't
-  notified. The allowed event and the bus log line are the only trace. A later publish on the
-  decision gets decision-consumed, which tells the agent the decision was used. Whether the run
-  should get a RESULT for a late record is a follow-up question for Sage.
- The hold lives in the bus process's memory, like the broker's open tickets. A bus restart during
-  a hold drops both, the same as today for any publish in flight.

-`packages/cli/src/git-socket.mjs:351` allows one landing per socket at a time. `finishLand` moves main by
-compare-and-swap (`packages/seat/src/working.mjs:391`, refusing `base-moved`). `recordLand` reruns
-`#landFacts`, which refuses `decision-consumed` (`packages/bus/src/broker.mjs:945`). So no end-to-end race
-exists, and no code change is planned. What's missing is a test that pins each guard.
-
- In `packages/bus/tests/land.test.mjs`, add a test where two tickets pass `checkLand` on one decision. The
-  first `recordLand` succeeds and the second refuses `decision-consumed`, with nothing recorded for it.
- Run three mutants and list them in BUILD.md: drop the `#spent` line in `#landFacts`, drop the old value
-  from the CAS `update-ref` in `finishLand`, and drop the `land-busy` throw at git-socket.mjs:351. Each must
-  be killed by a named test. If the CAS mutant survives `packages/seat/tests/working.test.mjs:555`, add a
-  test to working.test.mjs that kills it. Otherwise leave that file alone.

-Owner Honker, reviewer Duckworth, gate owner Sage. Builds on row 194's landing.
-
-Row 194 b3 checks the revision in `instance-settings.mjs` `commit()` before `beforeWrite`, which is the revoke on
-fire and delete. A window is still open. If a write lands between that read and the writer's lock, a fire or
-delete revokes and then refuses `revision-conflict`. An `outcome-unknown` after a revoke also doesn't say the
-tokens are gone. Two changes:
-
-1. Run `beforeWrite` inside `writer.write`, under its lock, after the `organization.mjs:188` revision check. A
-   refusal after a revoke that ran says the tokens may already be revoked. That covers `revision-conflict` and
-   `outcome-unknown`, in the CLI and the Console texts. A refusal before any revoke keeps today's text.
-2. Add a fire test for a stale revision, using an injected writer or whatever the design picks. The test checks
-   that nothing is revoked and the business file is unchanged. Keep T21 for delete.
-
-Mutants: run `beforeWrite` before the lock. Drop the fire refusal. Drop the "may already be revoked" text.

-owner Sage. Darkwing builds it right after I3, and it must land before the ops-01 proof.
-
-### Problem
-
-The host run sheet (I3, line 182 above) lists r6's `hostcheck` among the host items for any host that runs
-bwrap, and I3's A1 refuses `profile-drift` unless `/usr/local/lib/mosaic-stack/hostcheck.sh --check` exits 0.
-No hostcheck exists on refactor. It's r6 B2 (row 195 DESIGN.md at b7239bb66, :262-303 and :839-860), sized at
-150-200 lines of bash and 350-450 of test. That's work separate from the upgrade sequence: the root-side bwrap
-stop and a network fetch.
-
-### What ships
-
-r6 B2 as designed:
- `case1-pins.sh` holds the pins: the profile sha256, the apparmor-profiles version and the bubblewrap pin.
- `hostcheck.sh` covers the seven items in three modes:
-  - `--check` exits 0 or 1.
-  - `--enforce` stops bwrap: `apparmor_parser -R`, then `root:root 0700` on `/usr/bin/bwrap`. It writes
-    `/etc/mosaic-stack/DRIFT` and a `hostcheck.log` line, and exits 0.
-  - `--upstream` compares the current apparmor-profiles deb to the pin.
- `mosaic-hostcheck.service`, a boot oneshot.
- `case1-hostcheck.test.mjs` uses fakes for every host tool and covers r6's seven case groups and seven
-  mutants.
-
-The I3 run sheet's hostcheck item points at this row. I3's A1 and its fake don't change.

- Version 1.8 source, Jason's ruling Q188 (DECISIONS, 2026-10-20), his
-  answers to Q8 and Q10, in part. Q8: "I would rather grant the grant
-  right to an agent that runs with strict guardrails. That agent presents
-  the final authorization for the user. Upon approval, the grant is
-  created programmatically. I see this as: User configures their PATs, API
-  tokens, authorizations within the WebUI. The agent presents the request
-  for grant with X rights for another agent. The user reviews, then clicks
-  Approve/Deny. Click of Approve fires off protected mechanical methods to
-  handle the grants on Github, Gitea, .... services as needed. The tooling
-  would need to exist and must be guarded." And "Disallowing the agents to
-  create grants autonomously is a necessary evil for better security.
-  Requiring the user to manually perform the steps is a no-fly." Q10:
-  "Agents should have tools and command access based on roles. Those roles
-  dictate the allowed tools and commands. The use of a tool or command
-  should not be raised to the user unless the system is configured with a
-  manual mode that requires user interaction. By default I want to have
-  the agents capable of running commands and tools at will within their
-  sandbox/guardrails. This allows autonomous actions by agents within
-  their lanes. Perhaps a "Trusted actions within approved guardrails"
-  methodology." And "The main agent or chief of staff would be responsible
-  for surfacing the request to the user's inbox for approval. Not all
-  agents are capable or authorized to request directly. It must follow the
-  chain of command properly." He agreed with Mos's Q10 points 3 to 6:
-  protected stack code does every step on Approve, his tokens are entered
-  in the WebUI and agents never see them, a command on the approved list
-  runs without a click and any other is refused, and he, Mos or the tester
-  can revoke a grant at once.
- Version 1.8 source, Jason's ruling Q190 (DECISIONS, 2026-10-20), his

- Version 1.8 source, Jason's ruling Q191 (DECISIONS, through Mos in

- Version 1.7 source, TARGET.md line 66: "Chief of staff agent has
-  hire/fire authority for agents as needed; unless user forbids per
-  agent". And Jason through Mos (mos-1067), DECISIONS Q183, in part: "I
-  will still want to allow infra agent(s) on my .53 instance to access
-  other servers, etc. However, not all agents will need to have that
-  access. I envision a credential store within Mosaic Stack that works as
-  some sort of variable for the agent to call. The system will enforce

-  security. I need to be able to trust my agents with assisting me. This

-  a decision each time. Hiring adds a role instance to the organization
-  file and lists it for launch. Firing ends the instance's runs and
-  removes it from the launch list. It stays in the organization file. Only
-  the user deletes an instance. These actions are `role.hire` and
-  `role.fire`. They leave the hard waits and route under this requirement,
-  within these bounds:
-  - The chief acts only in its own organization.
-  - The chief hires only role definitions that need no credentials, until
-    a later version adds credentialed roles.
-  - The chief hires only the role kinds its role file lists. Changing that
-    list is a reviewed commit.
-  - The chief hires only a role whose every action is on a fixed list of
-    plain work actions: sending messages, writing records, asking for
-    review, updating its assigned tasks, and the scope and working-push
-    actions of an assigned task. A role holding any other action, such as
-    launch, end, organization, naming, hire, review verdict or merge
-    authority, or any action added later, is never hired. So the chief
-    never hires a chief, never picks its own reviewers or merge gate, and
-    the author is never the reviewer. This holds whatever the role file's
-    list says. Adding to that list is a PRD change.
-  - The chief may set a hired instance's model and narrow its limits, and
-    nothing else about it.
-  - The user can forbid per agent. The user marks an instance so the chief
-    can't fire it, end its runs or change its model, and marks role kinds
-    the chief can't hire. Only the user changes these marks, through the
-    WebUI or the CLI.
-  - The kill switch stops every hire and fire while it is on.
-  - Every hire and fire is logged with the chief's instance, its run and
-    the reason.

 ### Variables

@@ -379,111 +289,8 @@ Added in version 1.7:
  - in Vikunja, a `bot-<business>-<role>` user per role, plus one
    read-only `bot-<business>-sync` that does all polling (lead
    decisions 52 and 58).
-
-  Since version 1.8, a token or key for a grant is made by the grant code
-  on the user's Approve (REQ-GRANT-2), not by hand. Tokens that exist stay
-  as they are.
 - **REQ-CRED-2.** A session that finds only founder credentials stops.

-Added in version 1.7:
-
- **REQ-CRED-3.** An agent with a grant can run commands with sudo on
-  another host. The agent asks for the host credential by name. The stack
-  checks that a grant exists for that agent and that host before the
-  credential is used. The agent never sees the key or any other secret
-  value (REQ-CRED-1, REQ-VAR-2). An agent without a grant for that host is
-  refused. Not every agent gets a grant. Who grants a host credential, and
-  how, is set by the #424 design, which Jason approves.
-
-Added in version 1.8 (Q188):
-
- **REQ-CRED-4.** An action a role definition lists within-role, and that
-  uses a grant, runs without a decision for each use only when all of
-  these hold:
-  - the definition declares the credential kind the action uses;
-  - a grant names that agent, and that host or service;
-  - for a command, the command matches the grant's allowlist. A grant
-    lists exact argv prefixes. A wildcard grant is refused;
-  - the agent's key or token for that grant is issued and not revoked.
-
-  A command off the allowlist is refused, and adding one takes a new grant
-  request (REQ-GRANT-1). An action whose definition doesn't list it
-  within-role still needs a decision for each use. Only a reviewed role
-  change adds an action to a definition. `host.sudo` routes under this
-  requirement.
- **REQ-GRANT-1.** No agent creates or writes a grant. A grant request
-  follows the chain of command, and only the chief of staff raises it to
-  the user's inbox. Any other role that needs a grant for itself or for an
-  agent it directs asks the chief of staff, through its chain: a worker
-  role through its PM, the PM and the CTO directly. The assistant passes
-  the user's own request to the chief of staff (REQ-ASSIST-1). The request
-  names the agent, the grant method and its target, the exact rights, and
-  a rotate-by or expiry date. The chief raises one only for an agent whose
-  reviewed role definition allows that kind of credential, and the broker
-  refuses any other. A grant can't name a wildcard, a shell or an empty
-  command. The request is a decision with the action `credential.mint`, so
-  it goes to the user as a hard wait (REQ-WAIT-1). A grant whose method
-  makes an account, such as a seat's own Gitea user (Q190), is the same
-  one decision: the method in the grant says it makes an account, the
-  request names the account, and the inbox shows the account name before
-  Approve. The user's one resolution covers the account and its
-  credential, so the hard-waits list doesn't change. An `account.create`
-  raise isn't a grant request and routes as version 1.7 has it. The broker
-  checks only that the chief of staff raised the request. The chain of
-  command before that is in the messaging lists and the role contracts,
-  not a broker check. The assistant and the chief of staff are separate
-  roles. No agent holds both, and the broker refuses a claim that would.
- **REQ-GRANT-2.** The user approves or denies each grant request in the
-  inbox. Approve is the only thing that creates a grant, and the code uses
-  a grant only when it has a matching Approve record. No agent creates a
-  grant. A grant written into the business file by hand makes nothing. Row
-  210's hand-written grants stay a test path until Vikunja #436a moves
-  `host.run` to grants made by Approve. On Approve, protected stack code
-  does every step, not an agent and not the user: it records the grant,
-  makes the key or token, installs it on the machine or creates it on the
-  service, and logs each step. On Deny nothing is made, and the denial is
-  logged. The grant methods are:
-  - machine key: a key for one agent on one enrolled host, with the
-    command allowlist of REQ-CRED-4. A host's identity comes from the host
-    side when the user approves its enrollment, never from a first
-    connection. A host user with sudo receives a grant only after the user
-    approved that user by name;
-  - Gitea: a token for one agent, and for an agent seat its own Gitea user
-    (Q190), with an expiry. The all scope and the admin scope are never
-    granted;
-  - GitHub: a grant for one agent.
-
-  The Gitea and GitHub rights units come in a later design that Jason
-  approves.
-
-  The approval binds the exact rights the user saw and the target or its
-  enrolled identity. A change to the agent, its definition, the target,
-  the target's identity or the rights after the raise voids it. An
-  approval is used once. A grant the code couldn't finish is undone at
-  once on the stack's side, so it is never used. What it left on the host
-  or service stays visible as pending until it is removed, as for a revoke
-  (REQ-GRANT-4). A new grant needs a new approval, never an automatic
-  retry. The grant code runs only on a request the user resolved. A
-  request resolved by an arbiter, the tester or any agent makes nothing. A
-  `credential.mint` decision raised before version 1.8, or without the
-  fields of REQ-GRANT-1, makes nothing when it is approved. Until the
-  Console knows the signed-in human (Vikunja #412), Approve is
-  `mosaic decide` in the CLI (REQ-DEC-3).
- **REQ-GRANT-3.** The user enters their own personal access tokens and
-  API tokens in the WebUI, or the CLI. Only the grant code reads them, to
-  make grants. No agent ever sees a token value or a key's private half.
-  Values appear in no event, log, message, prompt or agent file, and no
-  agent can read them back (REQ-VAR-2). Until the Console knows the
-  signed-in human, they are entered through the CLI.
- **REQ-GRANT-4.** A grant can be revoked at once by the user, by the
-  assistant for a grant in its own organization, or by the tester on a dev
-  instance (Q173). A revoke needs no decision and no new trust. It takes
-  effect at once on the stack's side, without waiting on the network, so
-  the next use is refused. Removing the key or token at the host or
-  service follows. Until that removal is done it stays visible as pending.
-  A revoke while the grant is being made stops it, and nothing it made
-  stays usable. Every revoke is logged with who made it.

-
- **REQ-TRUST-1.** Agents act within their role guardrails without asking.
-  The default mode is "trusted actions within approved guardrails". An
-  action a role file grants within-role is done at will, inside the
-  agent's sandbox, its tool limit and its grants, and is logged. It raises
-  nothing to the user. An action the file doesn't grant within-role still
-  routes by REQ-DEC-2, and a hard wait still goes to the user
-  (REQ-WAIT-1). Only a reviewed role change adds an action to a role file,
-  and REQ-WAIT-2 still keeps every hard wait out of every role file.
- **REQ-TRUST-2.** The user can put chosen actions in manual mode. The
-  organization file holds the list of actions in manual mode, empty by
-  default. While an action is on the list, every use of it by any role
-  becomes a decision for that use, raised to the user, and the action
-  waits until the user resolves it. A decision denied, or not resolved,
-  refuses the action. Each decision is used once. For a command on another
-  host, the decision names the host, the command and its input. Actions
-  not on the list are unchanged. Only the user changes the list, through
-  the WebUI or the CLI. The chief of staff's organization writes
-  (REQ-ROLE-3) can't change it, and no agent can. Every change is logged

-Added in version 1.7:
-
- **REQ-LAND-2.** A coder pushes its own work to its own fork. The action
-  is `git.push.remote`.
-  - What it pushes: one commit, by its oid, never a ref name. That commit
-    is the latest work commit the bus recorded for the coder's task, and
-    the coder made that push. A decision that authorizes a push names that
-    commit, and it doesn't authorize any other.
-  - Where it lands: only the branch
-    `refs/heads/<its Gitea user>/<branch>`. The host builds that name, the
-    agent never does. A push never forces.
-  - Which remote: the agent's own fork of the project's upstream. The
-    business file names the upstream, and the host never contacts it. For
-    each push the host builds the fork's address over https from the
-    upstream's host, port and repository name and the agent's own Gitea
-    user. The history check, the push and the credential match all use
-    that address. So the agent's own user owns the receiving repository on
-    every push, and the agent never names it.
-  - The host refuses an upstream on a host or port other than the agent's
-    Gitea, and an upstream the agent's own user owns. It refuses a fork
-    that is missing, empty or doesn't share the project's history. Gitea's
-    push-to-create stays off, so a push never creates a repository.
-  - Who may: the action routes under REQ-DEC-2 and is granted within-role
-    to the coder role only. No other role file grants it.
-  - Before version 1.7 the action was a hard wait under REQ-WAIT-3, so
-    each push needed a decision the human resolved, and that decision
-    named the commit.
