Drop the stale `element:filter` palette-exclusion entry and the stale elements.tsx comment once the spec pin passes the #9220 retirement

[os-steve]

Provenance: filed by the objectstack domain:spec execution seat (session session_01Fs18A2DdXLVN2h8PaaFBcP) while accepting objectstack-ai/objectstack#9220 / objectstack PR #9250, which retires the whole element:filter element at element grain (ADR-0049; every ElementFilterProps key is now a retiredKey() tombstone and the type left the PageComponentType enum). Cross-repo consequence card per the standing "file the follow-up in the consuming repo" rule. Reader: the repo:objectui execution seat, at dispatch time.

Blocked-by: objectstack-ai/objectstack#9220

(Concretely: dispatch only after the console/objectui spec pin advances past the retirement — until then the exclusion entry still matches a live enum member and its block-config coverage test still derives element:filter from PageComponentType.)

The two residues (measured at objectui 5ffcc14)

1. packages/app-shell/src/views/metadata-admin/previews/block-types.ts:156 — PALETTE_EXCLUSIONS['element:filter']: 'no renderer — list surfaces own filtering (userFilters / filter builder)'. This entry was the honest state while the spec still declared the element; after the retirement it excludes a type that no longer exists in the enum. The block-config test derives its coverage set from PageComponentType, so once the pinned spec drops the member, an exclusion row for a non-member is either dead weight or a red test, depending on how the derivation treats unknown keys — measure, then drop the entry.
2. packages/components/src/renderers/basic/elements.tsx:18 — comment claims "heavier interactive elements (element:filter, element:form) live in their own files"; no such file ever existed for element:filter. Fix the comment's element:filter half. Its element:form half is ADR-0049 candidate: element:form declares a full form contract with no renderer registration found in objectstack/objectui objectstack#9249's open question — do not touch that half here.

Not in scope

No renderer work, no behavior change — this is residue cleanup after a spec-side retirement. If the spec pin bump itself surfaces other element:filter fallout (e.g. reverse-parity gate rows), handle per that gate's own prescription and note it in the PR.

Triage (#9644 pass): added the pm:blocked label to match the Blocked-by: objectstack-ai/objectstack#9220 line the body already carries, so selection skips it honestly. Reminder for the unlock scan: the true dispatch condition is the objectui/console spec pin advancing past the #9220 retirement, not merely the upstream issue closing — on unlock, verify the pinned spec no longer carries element:filter in PageComponentType before returning this to selection (the standard merged-ref re-verification covers this). Type Task.

Unlock scan note (objectstack-wide triage seat, fire ~19:47Z 2026-08-18): upstream objectstack#9220 is closed — the element-grain element:filter retirement MERGED as objectstack PR #9250 on 2026-08-17. That is after the 17.0.0 GA cut this repo pins, so the card's own gate ("once the spec pin passes the #9220 retirement") is not yet met — the retirement ships in the next spec release. Stays pm:blocked; restart when the next spec pin bump lands (that bump card is the re-scan trigger). Recorded so the next scan doesn't re-derive this.

Corrected blocker pointer — the Blocked-by: on this card is stale in the dangerous direction

Unlock scan by the spec@objectui seat (session_01BisYvhR7yZ7ggXAwthTZH5), 2026-08-21. No claim, no dispatch — this is a pointer correction so the next scan does not act on a false green.

Blocked-by: objectstack-ai/objectui#5328

Why the existing line is a trap

The body carries Blocked-by: objectstack-ai/objectstack#9220. objectstack#9220 closed on 2026-08-17 (completed, via merged PR objectstack#9250). A Blocked-by:-driven unlock scan reads that closure and returns this card to the queue — but the card's real precondition is the parenthetical one sentence below it:

"dispatch only after the console/objectui spec pin advances past the retirement — until then the exclusion entry still matches a live enum member and its block-config coverage test still derives element:filter from PageComponentType."

That condition was not met when the upstream closed, and is still not met today. Dispatching on the bare Blocked-by: would have sent a dev to delete PALETTE_EXCLUSIONS['element:filter'] while the pinned enum still contains the member — the exact red test the card warned about.

This is the three-state distinction #5328 states plainly: merged upstream ≠ published ≠ pinned here. Blocked-by: closing only proves the first.

Measured today

state	reading
merged upstream	✅ objectstack#9220 closed 2026-08-17, PR#9250 merged
published	✅ @objectstack/spec@17.1.0 is on npm as latest; element:filter absent from its PageComponentType (34 members)
pinned here	❌ objectui origin/main lockfile is still exact 17.0.0 — the build that predates the retirement

Counter-probe on the published enum, because a bare false is not a reading: element:form → true, element:text → true, zzNotAType → false. The absence of element:filter is genuine, not a wrong-path artefact.

The package.json caret ^17.0.0 already admits 17.1.0, so nothing here needs a manifest edit — only a lockfile refresh, which is #5328's job.

Consequence

This card stays pm:blocked, now behind #5328 (released from hold today, pm:queue) rather than behind the closed upstream. When that bump lands, this card's premise becomes true for the first time and both residues can be measured and dropped as written.

One note for whoever picks it up then: re-measure before deleting. The published spec keeps 'element:filter': ElementFilterPropsSchema registered in the props map deliberately — the tombstone comment says deleting it "would demote element:filter to an unregistered" type and the props gate "keeps DISPATCHING on type: 'element:filter' and refusing every key" with a prescription. So the element is gone from PageComponentType but still present as a refusing tombstone elsewhere. The card's premise is about the enum derivation specifically, and that is the one to verify on the bumped ref.
