This matters most under re-delivery: pull-mode coordination (#1081) re-runs a turn whose worker died, so a task you receive may have partially run before. Check your own records and your earlier asks before repeating an irreversible effect; do the reversible parts first and gate only the irreversible step.

+`response_text`, never as `response` (the #2375 class), and no column was added.
+`validate_response_choice(item, response, *, response_text)` — `response_text`
+keyword-only and required, so a stale two-argument call fails loudly — handles
+the literal **before** membership: on a non-approval it is **422
+`reserved_value`**; with a blank/whitespace instruction it is **422
+`instruction_required`**; otherwise it is accepted regardless of the offered
+list. It is never filtered out of `usable_options`, so an approval whose only

+offered the literal itself gets the reserved meaning, not a second one. Every
+other unoffered string is still `response_not_an_offered_option`. Two more

+(a skill gate counts only `Approve`, and no agent reads the text) with **422
+`not_off_menu`** via `decided_by_options(item)`; and `ask_operator`'s raise
+path refuses an option equal to the literal (**422 `invalid_options`**). Both
+writers map the three `ReservedAnswerError` subclasses to named 422s
+(`{code, message}`), and `OperatorResponse.response_text` is bounded at 4000
+like the Workspace answer and the resume frame. The ent#329 resume frame says
+what the literal means in one platform sentence **above** the data fence; inside
+it the answer is `answer: (something else)` and the instruction stays under
+`notes:`. The contract text (platform prompt `approval` bullet and the queue-file
+write-back paragraph, `prompt.md`, the agent guide, the `ask_operator` /
+`get_my_ask` / `respond_to_operator_queue` descriptions) names the literal; a
+`test_1402_prompt_contract.py` sentinel pins it.
+
+Surfaces: every producer shows a **Something else** chip after the agent's
+chips (`offeredChips(item)` = `optionsOf` minus the literal and the size-cap
+marker, which also stopped the marker rendering as a pickable chip), neutral
+styled, never the index-coloured arms. On `QueueCard` / `QueueItemDetail` and
+the Workspace typing with no pick **auto-arms** the chip; the field label,
+placeholder and Send copy flip ("Send instruction", "Instruction (required)"),
+and Enter never sends an auto-armed state. `/m` gates its form on a pick, so
+there the chip is tapped first. Send needs the instruction everywhere
+(`buildQueueResponse` returns `null` for the literal with a blank note), inputs
+cap at 4000, and `respondToItem` now returns success so `QueueItemDetail`
+clears the form only when the send landed (a 409 divergence no longer wipes the
+typed text). **The chip is hidden on platform-minted approvals on every surface** —
+`decidedByOptions(item)` reads the boolean `decided_by_options` that both the
+Workspace ask projection and the operator-queue list/item projections carry
+(`ask_service.decided_by_options`, the sink's own predicate over every reserved
+id prefix; it says nothing else about the item, and the machine view omits it).
+The `gate-` id prefix is only the SPA's fallback for an item without the field.
+MCP `list_operator_queue` / `get_operator_queue_item` pass it through unchanged.
+So no surface offers an answer the sink would refuse; `not_off_menu` is the belt. A human
+never reads the token: resolved views (`ResolvedCard`, the Detail resolved

Synchronous: the portal's answer route is a plain `def` on a worker thread, so the audit and broadcast hop to the loop through `operator_resume_service.spawn_on_loop` and are never awaited. `_broadcast_payload` names each trigger so the ent#467 `/ws` guard reads it.
 
 **Only a person ends an ask.** `dependencies.reject_non_person_principal` (an allowlist over `mcp_scope ∈ {None, "user"}`, no `agent_name`/`connector_agent`/`portal_delegate`; a principal with no scope attribute fails closed) guards respond, cancel and bulk-cancel before anything is read → 403 `person_required`. The Workspace answer (`client_portal/asks/router.py`) holds its platform principals to the same rule: `get_portal_principal` sets `PortalPrincipal.is_person` from `is_person_principal`, so a system-scoped key keeps its Workspace read breadth (#2198) but its answer is refused with the same 403 before the row is read.

+## 2026-10-05 — pitfall — A PR that reverses a UI rule leaves the old rule's source-text pin red
+**Context**: trinity#3242, `src/frontend/tests/unit/workspaceAsks.spec.js`. #2375 pinned PortalAsks' Send button by its source text (`:disabled="… || !picks[ask.id]"`) to prove "no pick, no send". #3242 deliberately reversed that rule ("Something else" plus a typed instruction is sendable with no pick), changed the predicate to `!approvalSendable(ask)`, and ran only the new targeted specs — the old pin, outside that set, turned the full `npm run test:unit` red. The same pin had also kept a now-dead `optionsOf` import alive because it matched the exact import specifier list. Same class as trinity#2829 / #2918.
+**Lesson**: (1) When a change reverses a rule, grep the WHOLE test tree (vitest, pytest, mcp-server) for the old predicate's source text before calling the branch green, and run the full unit suite, not only the specs you wrote. (2) A `.vue` predicate that gates a store write is proven by a mounted behaviour spec, not by a regex over its source; when you meet such a pin, replace it with the behaviour test rather than re-pointing it. (3) Pin the module a component imports from, never its exact specifier list — a list pin forces dead imports to stay.

 - **Queue item** — A row in the operator queue. Three request types: `approval` (a yes/no or multi-choice decision), `question` (freeform guidance), `alert` (acknowledgement only). Created by the agent, consumed by a person.
-- **Options** — JSON array of choices for an `approval` (typically `["approve", "reject"]`, but agents may define richer sets like `["draft", "send", "discard"]`). The decision must be one of them.
-- **Decision and note** — The answer has two parts. The **decision** (`response`) is what the agent reads: the chosen option, the typed answer to a question, or `acknowledged`. The **note** (`response_text`) is optional free text riding alongside a decision; it never stands alone.

 - **Ask** — A queue item addressed to one Workspace user (`addressed_to_email`). It appears in that person's Workspace, where they answer it, and stays visible to operators in the queue. An item with no addressee is for the operator alone.
 - **Priority** — `critical`, `high`, `medium`, `low`. Affects sort order in the queue.
 - **Response window** — Optional `expires_at`. After expiry the item moves to `expired`; the agent treats that as "not approved — do not proceed". An answer that arrives after the deadline is refused (`409 expired`), even in the few seconds before the platform sweeps the item.

 ## How do agents ask me questions or request approval before doing something risky?
 
-An agent writes the request to its operator queue file; a sync service polls running agents every 5 seconds and the item appears on the Operations page under **Needs Response**, where each card carries a type pill — **Needs approval**, **Question**, or **Heads up** — and the control matches the type. For an approval you pick one of the options the agent offered (`approve` / `reject`, say), optionally add a note, and send: the decision must be one of the agent's own options, and a free-text decision is refused (a 422 on the API). A question takes a typed answer; a heads-up just needs **Got it**. If the item stopped being pending while you were answering — another operator got there first, Clear All landed, or it expired — your response is not recorded and the page says so. The same cards work from the mobile admin at `/m`, where an approval is a tap on the option, an optional note, then an explicit **Send** — nothing goes out on a single tap. What the decision means to the agent, and when it acts on it, is on the approvals page. See [Approvals](../automation/approvals.md).

+- `approval` — You need a yes/no or multi-choice decision. Provide `options`, and state the exact action and its parameters in `proposal` so the operator can verify what they are approving. Never list `(something else)` as an option: the platform offers it on every approval. An answer of `(something else)` means none of your options is approved — carry out none of them; the person's instruction is in `response_text`, so re-plan from it or ask again.
 - `question` — You need freeform guidance. No `options` needed.
 - `alert` — You're reporting a situation. No decision needed; it goes to the operators.
