+fix(spec): the three shipped confirmation-gate prescriptions state the gate in the present tense — they were denying a door that exists (#17487)
+
+Clause-②: no
+
+No accept-set change and no export moves. `ToolSchema` still refuses
+`requiresConfirmation` with a located parse error, `ActionSchema` still accepts
+`ai.requiresConfirmation` in both directions, and `check:authorable-surface` /
+`check:api-surface` are byte-identical across this diff. What moves is text.
+
+Three customer-facing prescriptions were written while the runtime confirmation
+door was a separate, unlanded change, and each said so in the present tense. The
+door has since landed on `main` — `actionConfirmationRefusal`, called pre-dispatch
+by `invokeBusinessAction` in `@objectstack/runtime`, with the `confirm` member
+grown on the MCP `run_action` tool in the same change. From that moment the
+published prose DENIED a door that exists, and it denied it in the dangerous direction: an author who
+reads it concludes the safety flag stops nothing and either arranges a human in
+the loop some other way or stops setting the flag — losing the gate exactly when
+it starts working. That is the ADR-0049 false-compliance defect with the sign
+flipped.
+
+**The three carriers**, all of them shipped text rather than comments:
+
+1. the `requiresConfirmation` entry of `TOOL_RETIRED_KEY_GUIDANCE`
+   (`ai/tool.zod.ts`), which reaches consumers as the parse error on the
+   `.strict()` `ToolSchema` — the one channel every consumer bumping
+   `@objectstack/spec` is guaranteed to hit;
+2. the ADR-0087 D3 entry's `replacement`, and
+3. its `acceptanceCriteria` — what `spec-changes.json`,
+   `docs/protocol-upgrade-guide.md` and `os migrate meta` project to consumers.
+
+FROM → TO, on the sharpest of the three (the acceptance criterion):
+
+```
+was:  Do NOT try to "prove the gate" by invoking the operation without the
+      confirmation member: ... before that ships the call is not refused, it
+      RUNS the destructive operation.
+now:  ... that gate is PERFORMED: invoking the operation over an AI-exposed
+      door without the confirmation member is REFUSED with
+      ACTION_CONFIRMATION_REQUIRED (428) and nothing runs, so that call is a
+      real check you can make rather than a destructive experiment.
+```
+
+**The corrections carry the door's BOUNDS, because over-promising here is the
+same defect in the other direction.** Each prescription now states, as the door
+itself declares them: the refusal is `ACTION_CONFIRMATION_REQUIRED` / 428 naming
+the action and the member `confirm: true`; it is a GATE, not a queue — nothing
+is parked and a refused call did not run, no record read and none written; the
+enforced set is the doors that enforce the author's `ai.exposed` opt-in, today
+the action door reached from the MCP `run_action` tool, while REST `/actions` is
+not `ai.exposed`-gated and sits outside the gate; only the author's declared
+`ai.requiresConfirmation: true` refuses, while the wider listing heuristic
+advises and never refuses; and `confirm: true` is an unverifiable caller claim,
+so the gate makes FORGETTING loud without proving a human.
+
+`ai/tool-confirmation-prescription-tense.pin.test.ts` is the tie that was
+missing the first time: it reads the three shipped strings AND the runtime door,
+so a prescription that re-acquires a not-yet-shipped denial fails, and a door
+that is removed, narrowed off the DECLARED flag, unhooked from
+`invokeBusinessAction`, or widened onto REST `/actions` fails naming both files.
+The denial predicate is fed the three retired sentences verbatim, so it cannot
+pass by the prose merely falling silent.
+
+**On release ordering.** The door ships in the same release this correction
+does: the runtime changeset that carries it (`action-confirmation-gate-enforced`)
+is still pending alongside this one, and one `changeset version` run consumes
+both. A release cut before this lands is the failure this card exists to end —
+the runtime refusing calls while the published spec text tells authors the flag
+stops nothing.

Deleting the key mechanically would be the worst possible transform here: it would leave the metadata parsing green while silently completing the removal of a safety gate the author believed was in place. `ToolSchema` was made `.strict()` in the same change, which is load-bearing rather than tidying — removing a key from a non-strict schema swaps one silent no-op for another, so the retired key now REJECTS and the parse error carries the prescription, that being the one channel every consumer bumping `@objectstack/spec` is guaranteed to hit.
