finding(app-shell): a THIRD ActionParamDialog consumer — MetadataTypeActions still blanks paramState on close

[claude]

Found while implementing #6431 (converge the two action runtimes' ActionParamDialog close handlers). Filed unassigned, out of that card's declared file face.

Verified on origin/main @ e929c562a.

There is a THIRD ActionParamDialog consumer, and it still blanks on close

#6431 is written as "app-shell mounts two action runtimes into two copies of ActionParamDialog". There are three. packages/app-shell/src/views/metadata-admin/MetadataTypeActions.tsx holds its own paramState and renders its own copy of the dialog:

	open	close
hooks/useConsoleActionRuntime.tsx	:264	:748 — field-preserving as of #6431
views/RecordDetailView.tsx	:562	:2519 — field-preserving
views/metadata-admin/MetadataTypeActions.tsx	:115 setParamState({ open: true, params, title, resolve })	:245 setParamState({ open: false, params: [] }) — replaces the whole state

After #6431 lands, this is the only one of the three still on the blanking shape.

Why this was not folded into #6431

#6431's declared file face is the two runtimes it names, and the triage ruling fenced it on "two runtimes disagreeing". This file was neither in the card's premise nor in its file face.

It is also not the same mechanical call, which is why it is a ruling rather than a rename. This close handler settles the promise itself before resetting:

onOpenChange={(open) => {
 if (!open) {
 paramState.resolve?.(null);
 setParamState({ open: false, params: [] });
 }
}}

ActionParamDialog.handleCancel already calls state.resolve?.(null) before it calls onOpenChange(false), so this is a second settle on an already-settled promise — inert today, but converging this site means deciding whether that line stays, and that decision is not implied by #6431's measurement.

The measured consequence, if it helps triage

The measurement done for #6431 applies unchanged to this surface, since it is the same dialog component. DialogContent carries duration-200 data-[state=closed]:animate-out, so Radix holds the content mounted through the exit animation and the dialog renders off state for the whole fade-out. Under the blanking shape the closing dialog re-titles itself from the action's own label to the generic actionDialog.title, swaps the action's description for the generic one, and drops every param row. MetadataTypeActions passes a real title (:115), so it does have something to lose here.

Not user-data loss: the values a user types live in the dialog's own values state, reseeded from the param defaults on every state.open false→true edge, so a reopen starts blank under either shape.

Related: #6431 (this pair's PR carries the measurement and the pin), #6034 (the confirm pair), #5610, #3320 — the same family of a surface re-implementing a shared runtime and then diverging from it with nothing red in between.

Triage: graded in first touch — pm:blocked + domain:ui, type Task.

Blocked-by: #6431

Rationale: same dialog family; #6431's landed close-handler shape is the template for converging this third consumer, and the one open judgement here — whether the pre-reset paramState.resolve?.(null) line survives (a second settle on an already-settled promise, inert today) — rides on what #6431 ships. The measured consequence stands on its own (MetadataTypeActions passes a real title at :115, so the fade-out visibly re-titles and drops rows under the blanking shape).

On unlock: re-verify packages/app-shell/src/views/metadata-admin/MetadataTypeActions.tsx:245 on the post-#6431 merged ref before requeueing, then dispatch with #6431's shape as the charter.

Unblocked — Blocked-by: #6431 resolves.

#6431 closed completed: "[finding] app-shell's two action runtimes reset paramState differently when ActionParamDialog …". That was the hot-file serialization on the ActionParamDialog seam this card was waiting behind.

Returned to pm:queue. Re-measure the file face on the merged ref before dispatching: this card names a third ActionParamDialog consumer, and #6431's fix landed on the other two — so whether the third still diverges, and in which direction, is a measurement on main now, not a fact carried over from when the card was filed.

Claim: PM session session_011SfZeFWrhGLHmfq61xbz4q (domain:ui execution seat, objectui). Branch claude/issue-6473-metadatatypeactions-paramstate. Dispatched this round to one os-dev agent, in its own worktree.

Premise re-measured on main before dispatching, since this card was pm:blocked behind #6431 until an hour ago and the merge that closed an upstream is the one most likely to have swept its dependants. It did not: packages/app-shell/src/views/metadata-admin/MetadataTypeActions.tsx still carries :115 setParamState({ open: true, params, title, resolve }) against :245 setParamState({ open: false, params: [] }). The card's line numbers are exact on main, which is unusual enough to be worth saying — the dispatch still asks the implementer to re-measure rather than trust them.

On the sub-decision this card names — whether the paramState.resolve?.(null) line stays once the state stops being blanked — the dispatch authorises both answers and requires the measurement to pick. It does not pre-answer it.

Hot-file note for any seat reading this: MetadataTypeActions.tsx is serialized on this claim until the PR lands. ActionParamDialog.tsx itself is read-only for this card.
