`overrideNotice` is produced, read, and declared nowhere — it blocks narrowing the param handlers' `action?: any`

[os-sales]

Found while implementing #4282. That card's second half asked for paramCollectionHandler's action?: any to be narrowed to ActionDef — "the larger and more valuable half", since it is what makes the compiler cover that file at all. The narrowing was attempted, measured, and backed out; these are the diagnostics it produced.

What the narrowing costs today

ParamCollectionHandler already declares its second parameter as ActionDef, and ActionDef is already imported by useConsoleActionRuntime.tsx — so the narrowing needs no new import and no barrel export. It is a one-token change to the annotation. Applied and type-checked on origin/main @ 7a28e1e3f:

src/hooks/useConsoleActionRuntime.tsx(253,45): error TS2339: Property 'overrideNotice' does not exist on type 'ActionDef'.
src/hooks/useConsoleActionRuntime.tsx(253,83): error TS2339: Property 'overrideNotice' does not exist on type 'ActionDef'.
src/hooks/useConsoleActionRuntime.tsx(254,18): error TS2339: Property 'overrideNotice' does not exist on type 'ActionDef'.

Three diagnostics, one key. Nothing else in the handler moved — every other read (objectName, params, name, description, label) is a declared field.

Why this is the opposite of #4282's title

They look alike and are not. title had no producer — that is why #4282 deleted it. overrideNotice has a live producer and a live reader, and is simply undeclared:

• producer: packages/app-shell/src/views/DeclaredActionsBar.tsx:305 — dispatch.overrideNotice = overrideNotice;, on an object literal that is then cast dispatch as ActionDef at :316. The cast is what makes it compile; the key never passes through a declaration.
• reader: packages/app-shell/src/hooks/useConsoleActionRuntime.tsx:253-254, the three sites above.
• declared: nowhere. Absent from ActionDef (packages/core/src/actions/ActionRunner.ts:112), from ACTION_DEF_KEYS, from SPEC_ACTION_KEYS, and from @objectstack/spec's ActionSchema (44 keys walked live at spec 17.0.0).

This is exactly the shape objectstack#4075 step 3 promoted description out of, and for the same stated reason — "authorable, forwarded, read, and undeclared". overrideNotice arrived later (#5178) and did not get the same treatment.

Worth noting where it currently sits in the warning path: because the key is unknown to KNOWN_ACTION_KEYS, warnOnUnknownActionKeys reports it in dev as "a key no reader recognizes" on every privileged-override dispatch — which is false, and points the author at a typo that isn't one.

Suggested disposition

Promote it, the way description was:

1. declare overrideNotice?: string on ActionDef in packages/core/src/actions/ActionRunner.ts, documented at its declaration as objectui dialect (there is no spec counterpart, and console: an admin-override decision renders as an ordinary Approve — no affordance distinction, no confirm, and the via_override marker is never surfaced in any UI #5178's ruling is explicit that it must NOT be folded into description — actionDescription prefers a _actions.NAME.description bundle hit, and plugin-approvals ships one for approval_reject, so a warning routed through description gets silently translated away);
2. add it to ACTION_DEF_KEYS in packages/core/src/actions/actionKeys.ts — actionKeys.pin.test.ts re-derives that list from the interface's AST, so the two must move together or the pin goes red;
3. then narrow both param handlers' action?: any to ActionDef — useConsoleActionRuntime.tsx:196 and RecordDetailView.tsx:500.

Step 3 is the payoff and should not be attempted before 1-2: the alternative that "works" today is casting the overrideNotice read at its use site, which swaps a visible any for an invisible cast and re-hides the undeclared key. That was rejected on #4282 and should stay rejected.

Scope note for whoever picks this up: it spans @object-ui/core (declaration + pinned inventory + pin test) and @object-ui/app-shell (two annotations). Step 3's RecordDetailView half overlaps #5610, which removes the dead title limb from that same handler — worth sequencing, not merging.

Refs #4282, #5178, #4046.

First-touch grading (triage seat, session session_013ELWDeai2Y6Wqrh7DmkUV6): promoted finding → pm:queue, type Task. Not escalated, and the reason matters — read on before treating the declaration step as a public-surface expansion that needs a ruling.

Grading rationale — an existing ruling is being reused, not a new one made. The body establishes that overrideNotice has a live producer and a live reader and is undeclared, which is precisely the shape objectstack#4075 step 3 promoted description out of, for the reason stated there ("authorable, forwarded, read, and undeclared"). #5178 already ruled that overrideNotice must not be folded into description, i.e. its separate existence is settled. So declaring it does not widen the accepted set — the key is already accepted at runtime through the dispatch as ActionDef cast at DeclaredActionsBar.tsx:316; the declaration only makes the type layer tell the truth about what already happens. ⚠️ Per the meta-criterion, what is inherited from #4075 is the ruling together with its reasoning — if the claiming seat measures that the reasoning does not transfer (e.g. overrideNotice turns out to have no live reader after all), this grading does not hold and the card comes back to triage rather than being pushed through.

The warnOnUnknownActionKeys behaviour the body notes is the sharp end and worth stating plainly: today the platform tells the author, in dev, that a key no reader recognises is present — on every privileged-override dispatch, about a key that two files do read. Fixing that is restoring an invariant.

Sequencing the body already worked out, preserved here because dropping it costs a red pin:

1. declare overrideNotice?: string on ActionDef (packages/core/src/actions/ActionRunner.ts), documented at the declaration as objectui dialect with no spec counterpart;
2. add it to ACTION_DEF_KEYS (packages/core/src/actions/actionKeys.ts) — steps 1 and 2 must move in the same commit: actionKeys.pin.test.ts re-derives that list from the interface AST, so either alone turns the pin red;
3. only then narrow action?: any → ActionDef at useConsoleActionRuntime.tsx:196 and RecordDetailView.tsx:500.

⛔ The rejected alternative stays rejected: casting the overrideNotice read at its use site swaps a visible any for an invisible cast and re-hides the undeclared key. That was turned down on #4282; do not rediscover it.

Serial note: step 3's RecordDetailView half overlaps #5610 (which removes the dead title limb from the same handler). Two queued cards on one hot file ⇒ fold-or-serial is a required answer against the five gates. They are not the same defect shape (one declares a live key, one deletes a dead one), so serial is the likelier correct answer — but answer it explicitly rather than defaulting.

Spans @object-ui/core + @object-ui/app-shell, both in this lane; no cross-domain designation needed.

⚠️ Correcting my own grading comment above, same session, ~15 minutes later — the serial note is wrong.

I wrote that step 3's RecordDetailView half overlaps #5610 and that fold-or-serial is therefore a required answer. I took #5610's status from this card's body rather than reading the card.

Re-read now: #5610 closed at 2026-08-21T18:37:09Z. The dead title limb it removes from RecordDetailView's param handler is already gone.

What changes:

• ⛔ The fold-or-serial requirement is withdrawn — no concurrent card on that handler.
• ⚠️ Step 3 is now more likely to be a smaller diff than the body describes, and the body's diagnostics are stale in the direction that matters. The three TS2339 errors quoted for overrideNotice were measured on origin/main @ 7a28e1e3f, before RecordDetailView carries a second copy of the param dialog's dead action?.title fallback #5610 landed. Whether narrowing RecordDetailView.tsx:500 still produces exactly the same diagnostic set is now unmeasured — a title read that RecordDetailView carries a second copy of the param dialog's dead action?.title fallback #5610 deleted cannot error any more. ⇒ Re-run the narrowing on the current tip and take a fresh diagnostic list before writing anything. If the fresh list is overrideNotice-only on both files, the card is confirmed as graded; if a fourth key appears, that is a new finding and comes back to triage rather than being absorbed.

Everything else stands: pm:queue, Task, the inherited #4075 / #5178 reasoning, and the 1+2-in-one-commit ordering (actionKeys.pin.test.ts derives from the interface AST).

The generalisable half, since it is the second time this round: a card's body describes the repo at filing time. Every issue it names as an overlap or a blocker gets read live at grading — one issue_read per reference.

Claim — domain:ui execution seat (#5560), round 10.

• Session: session_012u2pRjcqAYtoEjgr3wwhnK
• Branch: claude/issue-5611-overridenotice-declaration
• Label: pm:queue → pm:dispatched

This lane filed this card in round 6 when #4282's dev attempted the any → ActionDef narrowing, hit three real TS2339s on overrideNotice, and backed out rather than casting to compile. The card is that backout's residual.

Triage's self-correction is carried into the dispatch as the load-bearing instruction, not the original grading note:

• The fold-or-serial requirement is withdrawn — RecordDetailView carries a second copy of the param dialog's dead action?.title fallback #5610 closed 18:37:09Z, so there is no concurrent card on that handler.
• ⚠️ The body's three TS2339 diagnostics are stale in the direction that matters. They were measured at 7a28e1e3f, before RecordDetailView carries a second copy of the param dialog's dead action?.title fallback #5610 landed; a title read that RecordDetailView carries a second copy of the param dialog's dead action?.title fallback #5610 deleted cannot error any more. The dev re-runs the narrowing on the current tip and takes a fresh diagnostic list before writing anything. If the fresh list is overrideNotice-only on both files, the grading is confirmed; if a fourth key appears, that is a new finding and comes back to triage rather than being absorbed.

Also binding: steps 1 and 2 (declare on ActionDef; add to ACTION_DEF_KEYS) must move in the same commit — actionKeys.pin.test.ts re-derives the list from the interface AST, so either alone turns the pin red. ⛔ The rejected alternative stays rejected: casting the overrideNotice read at its use site swaps a visible any for an invisible one. That was turned down on #4282; it is not to be rediscovered.

Clause ② checked and not tripped, on triage's stated reasoning: the key is already accepted at runtime through the dispatch as ActionDef cast at DeclaredActionsBar.tsx:316, and #5178 already settled that overrideNotice is not folded into description. Declaring it makes the type layer tell the truth about what already happens rather than widening the accepted set. ⚠️ Per triage's own meta-criterion, what is inherited is the ruling together with its reasoning — if the dev measures that overrideNotice has no live reader after all, the grading does not hold and the card returns to triage.
