+# Row 252 build notes: Console inbox Approve and Deny for grant requests
+
+Seat: Scrooge. Reviewer: Webby. Issue #1753, Vikunja #435 (J2).
+Brief: `docs/plans/2026-10-21_console-inbox-approve.md` (blob b41676d06).
+Design: Gander's DESIGN.md at d218e14bd, approved by Webby at 5d8f0f4b5 (webby-0082) with manifest checks N1-N5.
+Base: aca16404c on branch `scrooge/row252`. Rebase onto the row 253 tip under a new branch name once 253 lands.
+
+## Status
+
+- Code, tests and docs are written. No test has been run yet, because Gander holds the gate slot for row 253 run 5 and Sage ruled no node until a CLEAR.
+- Everything in the Results section is empty until that run. Nothing below claims a pass.
+
+## Q188
+
+No agent creates a grant. Approve and Deny are human-only Console actions.
+
+- Only a console cap reaches `decision.preview.console` and `decision.resolve.console`. A console cap reaches nothing else (console-decide `J1, Q188`).
+- The socket refuses a console proof for any other verb before the proof check (`server.mjs`).
+- A console cap binds only through `authenticateConsole`, which needs the console proof (section 2): the same-tree `console-cli.mjs` wrapper, its own nonce, a direct same-tree `serve` parent, and a configured owner subject from the spawn environment.
+- `recordEvent` keeps `human.input` reserved, so no agent writes the record that lets a console close start the executor (console-decide `recordEvent keeps human.input reserved`).
+- A `via console` close without its matching `human.input` approves nothing (console-decide `J14`).
+
+## Manifest checks N1-N5
+
+- **N1.** Every `console.sso` subject is an owner of the business. Name is display only.
+  - `cli/src/config.mjs` carries `{provider, iss, sub}` per subject into the boot as `consoleOwners`. No sso means no key.
+  - `bus/src/runtime.mjs` validates the list (array, at most 512, exactly three non-empty strings each) and passes it to `verifyPrincipal`.
+  - Tests: cli config.test `Row 252 (Webby N1)` and principal.test.
+- **N2.** `human.input` is written in the same transaction, before `#approvedGrant`. The executor starts once, and a deny starts none.
+  - Tests: console-decide `N2, J13` checks the order by seq and that the grant runs once. `J15` checks that a deny starts nothing.
+- **N3.** The close notice comes from `from_run 'human-console'`, and `public/bus.js` shows "via console". `landing` and `#protectedEnd` stay CLI-only.
+  - Tests: console-decide `N2, J13` checks the notice. decide-browser `J17` checks the close-elsewhere line.
+- **N4.** `decision.resolve` is not a Console verb.
+  - `CONSOLE_VERBS` is exactly the two console verbs. The webui serve `BUS_VERBS` read list has no decision verb, and webui `cli.mjs` has no `decision.` string. `consoleCall` refuses anything outside `CONSOLE_VERBS`.
+  - Tests: console-decide `N4`, and decide-sso `N4`, which hits `/api/bus/decision.*` for 404 and covers the cli.mjs scan and the consoleCall refusals.
+- **N5.** `readProcess` keeps the five `MOSAIC_BUS_CONSOLE_*` keys in the env allowlist (`bus/src/human.mjs`). The human proof and its spawn are unchanged.
+
+## Design choices and tradeoffs
+
+- **Webui imports from the broker.** `webui/src/bus.mjs` imports `CONSOLE_VERBS` from `bus/src/broker.mjs`, which loads the broker module into the Console at import.
+  - I chose one source for the verb list over a second copy that could drift.
+  - If Webby prefers the copy, the alternative is a literal list plus a test pinning it equal to `CONSOLE_VERBS`.
+- **The Console transport shares humanCall's spawn.** `consoleCall` and `humanCall` share it as `transport()`, so `webui/src/bus.mjs` changed. The busCaller `business` default keeps `||` (the old falsy semantics), not `??`.
+- **Confirmations are held in memory in the serve process.** Their lifetime is 2 minutes, they are single use, and they bind the session, decision, choice and digest. The cap is a limit that never drops a live confirmation.
+  - A restart loses all held confirmations. The user clicks again and gets a new preview. Nothing is written until the resolve.
+- **No retry anywhere.** A resolve whose bus reply is lost answers `outcome-unknown`, the confirmation is spent, and the page says "Nothing was sent again."
+
+## Old tests changed (for Mos, per mos-1272)
+
+- **`webui/tests/shell.test.mjs`**, write-boundary test. Gating `done` waits on Mos's ruling.
+  - The `writes` list gains the new `fetch(url, ...)` in `decidePost`. It is first in file order (bus.js:362).
+  - The `method:` count goes from 7 to 8.
+  - A new assertion pins `decidePost`'s callers to `url` plus the two literal `/api/decisions/${enc(a.id)}/...` routes.
+  - No existing entry was loosened.
+- **`bus/tests/channel-proof.test.mjs`**, sha256 re-pins with a header comment:
+  - `bus/src/human.mjs` (N5 env keys) to bb13c146…c885.
+  - `webui/src/bus.mjs` (consoleCall and `transport()`) to 701f009e…5272.
+  - Any later edit to either file needs a re-pin.
+- `bus/tests/principal.test.mjs`, `webui/tests/tester-listener.test.mjs` and `cli/tests/config.test.mjs` have new tests appended only.
+
+## Mutant plan (design section 6, J1-J17)
+
+Each mutant is one edit to the named source. Run the killing test, then restore and compare the sha256 against the pre-mutant hash with `git status` clean apart from the build. Kill rules are written before the runs.
+
+| J | Mutant | Source | Expected kill |
+|---|---|---|---|
+| J1 | eligibility from the request, `#consoleResolution` returns non-null for any decision | broker.mjs | console-decide `J1, J2` (ineligible) |
+| J2 | hardcode `approve = yes`, `deny = no` | broker.mjs | console-decide `J2` (go/stop, deny listed first) |
+| J3 | owner from name or header, skip the owner match in verifyPrincipal | principal.mjs | principal.test `console requires…` |
+| J4 | skip the serve-parent walk | principal.mjs | principal.test `console requires…` |
+| J5 | accept the human nonce namespace | principal.mjs | principal.test `console requires…` |
+| J6 | reuse the session from the confirmation, skip the live session check at resolve | decision-http.mjs | decision-http `session that ends`, decide-sso `listener gates` (new session) |
+| J7 | keep the console cap bound after the call (skip `release` for kind console) | server.mjs | **open**: no new test pins release for a console proof. Before the run, check whether an existing server test kills it. If not, add one and name it in the report. |
+| J8 | skip the same-origin check | decision-http.mjs | decision-http `gates`, decide-sso `listener gates` |
+| J9 | resolve without a confirmation token | decision-http.mjs | decision-http `a confirmation then a resolve`, `bad body` |
+| J10 | drop the choice, decision or session binding | decision-http.mjs | decision-http `binds the session, decision and choice` |
+| J11 | skip the digest, closed or business check | broker.mjs | console-decide `J11`, `N2, J13` (second answer closed) |
+| J12 | do not spend the confirmation | decision-http.mjs | decision-http `a second resolve refuses`, `confirmations… one use` |
+| J13 | write via cli, or omit the subject in human.input | broker.mjs | console-decide `N2, J13` |
+| J14 | `#approvedGrant` accepts via console without the human.input | broker.mjs | console-decide `J14` |
+| J15 | start the executor on any resolved choice | broker.mjs | console-decide `J15` and `J2` (stop starts nothing) |
+| J16 | `decide` true without sso or send | serve.mjs, public/bus.js | decide-sso `J16`, decide-browser `J16` |
+| J17 | retry on outcome-unknown or auto-submit after preview | public/bus.js | decide-browser `J17` (post count stays at 7) |

+1. Run each touched test file whole, with TMPDIR under /mnt/storage/scratch/tmp.
+2. Run the bus, webui and cli suites.
+3. Run the mutants above, then the drift check against refactor.

+  denied on its decision page, only when the Console runs with both `--sso` and
+  `--send` and the page is signed in as a `console.sso` subject. The first click
+  POSTs `/api/decisions/<id>/confirmation` and shows what the answer does; only
+  Confirm POSTs `/resolve` with that one-use confirmation (two minutes, bound to
+  the session, decision and choice). Each step spawns
+  `packages/bus/src/console-cli.mjs`, which the bus verifies as the Console's
+  child holding the signed-in subject, and the bus records the answer `via
+  console` with a `human.input` naming that subject. Nothing retries; an unknown
+  outcome says to refresh. Without `--sso` the page has no buttons and says why;
+  under `--sso` without `--send` it says the Console is read-only for decisions.
+  The tester listener has no decision routes. Every other decision stays
+  terminal-only.
 - What no Q1 verb returns is labelled where it would show, for example
  "Bot names: not in the Q1 module" (lead decision 63). Nothing is guessed.
 - A task's list row can only say its current state came from a Vikunja read,
