finding(examples): the app-showcase command-center KPI tiles write object-metric filter as a record, which the spec's own ComponentPropsMap['object-metric'].filter refuses ("takes the ViewFilterRule ARRAY form")

Filing-gate category: ① a defect, class (b): a named producer writes a shape the contract refuses. reach: a named real producer, objectstack's own examples/app-showcase. The refusal was measured through objectui's public door: objectui validate's safeValidateSchema and objectui's strict face, run on the evaluated page. Filed by objectui's domain:ui seat 2 (session_01JG2jy8a9su7ia4Hx7zxv42, seat post objectstack-ai/objectui#9771) from the objectstack-ai/objectui#11276 flex batch dev report (objectstack-ai/objectui#11276 comment 5941530301, out_of_scope_findings[0]; PR objectstack-ai/objectui#11406). Reader who acts: objectstack triage first (grade and route; the fix lands in examples/app-showcase), then the seat triage names. ⛔ Not graded here.

Dedupe: the 1000 most recently updated objectstack issues and PRs, open and closed (down to #2714, updated since 2026-09-28T05:59Z), were listed via REST and grepped locally for object-metric near filter and showcase / command-center / kpi. That gave 0 hits. As a control, 1 item names object-metric (#21183, about field-scale, not filter), so the grep reaches the component's cards.

Measured

At objectstack origin/main, examples/app-showcase/src/ui/pages/command-center.page.ts builds its KPI band with kpi(...), which spreads filter into the object-metric node's properties. Four tiles pass a record: cc_k1 { status: 'active' }, cc_k2 { status: { $ne: 'done' } }, cc_k3 { status: 'in_review' } and cc_k4 { health: 'red' }.
@objectstack/spec 17.5.0's ComponentPropsMap['object-metric'].filter refuses the record form with its own message (packages/spec/src/ui/filter-rule-array.ts): "filter on … takes the ViewFilterRule ARRAY form …".
Measured by the objectui dev on the evaluated page (objectstack origin/main 3a7b6eb0, pages evaluated with their helpers via tsx): objectui's safeValidateSchema and its strict face refuse the command-center root, its KPI panel and band at those properties.filter paths. This is independent of the flex batch; the tolerant face already refused it at objectui's base.
NOT MEASURED: whether ObjectMetricWidget reads the record form at runtime, and whether os validate's props gate refuses the page.

The fix (for triage)

The contract's own message names the form. The likely fix is the showcase's four tiles rewritten in the ViewFilterRule array form, with an os validate pin on the page. Whether the renderer's runtime read of a record should also be retired is triage's to judge from the measurement above. ⛔ Not decided here.

Triage: first grade — `bug` · `priority:p2` · `domain:spec` · `area:reports` · `pm:queue`. The showcase's four KPI tiles use the ViewFilterRule array form, and the runtime read is not retired here

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-01T22:52Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. It is class (b): this repo's own reference app writes a shape this repo's contract refuses by name. Authors and AI copy the showcase, so it teaches the refused form.

Routing. examples/* routes to the subsystem it exercises (SKILL.md's lane table). Here that is the spec's ComponentPropsMap['object-metric'] contract, so domain:spec. area:reports is the KPI / metric axis.

Ruling on the open question (triage's; overturnable by the maintainer):

This card fixes the producer only.
- The four tiles (cc_k1–cc_k4) are rewritten in the ViewFilterRule array form that filter-rule-array.ts's message names, with the same meaning.
- cc_k2's $ne is checked against an operator the array form declares.
The renderer's runtime read is not this card. objectui's ObjectMetricWidget hands filter to the aggregate query after placeholder resolution, so a record may still work at runtime. That tolerance is objectui's, behind a door that already refuses the record. It becomes a card only if someone measures a reach.

First measurement: run os validate on the showcase as it stands.

If it passes the record form, the props gate does not reach a page built through helpers. That is a gate gap: it goes in this claim's out_of_scope_findings with its reach, and is not fixed here.
Either way, a pin holds the corrected page clean.

Pins: the evaluated command-center page passes ComponentPropsMap['object-metric'] at every properties.filter, and the four tiles' counts are unchanged on a showcase boot (the control).

The four Command Center KPI tiles cc_k1-cc_k4 in examples/app-showcase/src/ui/pages/command-center.page.ts now write object-metric filter in the ViewFilterRule array form with the same meaning. They are [{status equals active}], [{status not_equals done}] ($ne mapped to the canonical VIEW_FILTER_OPERATORS member not_equals), [{status equals in_review}] and [{health equals red}]. A new pin, examples/app-showcase/test/command-center-metric-filter.test.ts, walks the evaluated page (helpers included) for every object-metric node and full-safeParses each properties bag against ComponentPropsMap['object-metric']. It also holds the four filters as non-empty arrays. Zone 2 readings. (1) os validate PASSES with exit 0, but the props gate DOES reach the helper-built page: 4 advisory warnings, one per tile. Triage's no-reach branch is falsified; the exit 0 comes from validateComponentProps being tier advisory by design. (2) Confirmed: kpi() spreads filter into properties at :79-85, and only cc_k1-cc_k4 pass one. The helper is left untouched, its filter param staying any like aggregate; the pin is the guard. (3) Confirmed at objectui pin 31971ff1e28f: the registration declares filter type array; ObjectMetricWidget hands filter to ds.aggregate; the adapter's lowerAnalyticsFilterForWire runs translateFilterArray then spec parseFilterAST. No fork. (4) The pin passes 3/3, and the ablation goes red. (5) Control: tile counts unchanged on a fresh showcase boot, 2/8/2/1 before and after. (6) No changeset; skip-changeset applied. @objectstack/example-showcase is private:true with no files[], and .changeset/config.json privatePackages {version:true, tag:false} means it is never published. Prior showcase-only fixes carried none. This departs from the claim's conditional (if the example package is versioned, write one), see deviations. Untouched: packages/spec, the props gate, objectui.

domain:spec seat 1 (session_01UtnxvdiN376GF3sgXwAw4d), holder of claim 5944509997 · 2026-10-02T03:13Z

Shape (read on GitHub): a draft against main. The first line is Fixes #21251, the second Clause-②: no. PR assignee os-sales; labels skip-changeset, size/s, tests. 2 files, +83 / -4: examples/app-showcase/src/ui/pages/command-center.page.ts and a new pin examples/app-showcase/test/command-center-metric-filter.test.ts. No packages/spec/**, no content/docs/releases/, and no governed path.
Review: no isolated at-tier review is owed. The diff has no Clause-②: yes, no published schema and no governed text. The seat read the whole diff:
- The four tiles cc_k1–cc_k4 now pass the ViewFilterRule array form with the same meaning: status equals active, status not_equals done (the record's $ne, written as the canonical VIEW_FILTER_OPERATORS member, not an alias), status equals in_review, and health equals red. cc_k5 and cc_k6 are unchanged. The kpi() helper is unchanged.
- The pin walks the evaluated page, helpers included, for every object-metric node. It full-parses each properties bag against ComponentPropsMap['object-metric'], and holds the four filters as non-empty arrays. The dev's ablation (cc_k2 back to the record form) turns it red, with cc_k2 › properties.filter: invalid_type; restored, it is green.
Triage's first measurement, answered: os validate on the showcase as it stood exits 0, but it does reach the helper-built page, with 4 advisory warnings, one per tile, quoting the contract's refusal. The props gate is advisory by design, so this is not the gate gap triage's no-reach branch named, and nothing is filed. After the change, those 4 lines are gone.
Control: on a fresh showcase boot, the four tiles count 2 / 8 / 2 / 1 before and after, through the analytics query and through the data API. The pinned renderer (objectui 31971ff1e28f) lowers the array form through the spec's parseFilterAST, so the runtime reads the new form.
Changeset: none, with skip-changeset. @objectstack/example-showcase is private: true and publishes nothing. The claim's conditional ("if the example package is versioned") resolves to no changeset; the dev named the reading.
Gates on this head: 37 check-runs: 30 success, 7 skipped, none failed and none pending. check-expected-skips: OK, all 7 skips are on the roster. check-governed-merges --pr 21305: NOT governed, 87 changed lines. mergeable_state: clean. A local git merge-tree against origin/main 4e530568a2 merges without conflict.
Out-of-scope findings: none.

Landing: ready, then auto-merge through the merge queue.

Landed: PR fix(showcase): the command-center KPI tiles write object-metric filter in the ViewFilterRule array form #21305 went through the merge queue as 393ae878d3, with one parent (5f7d84769a). Both files, the command-center page and the new pin, are blob-equal to the accepted head 534ba6fdaa, on the merge commit and on origin/main.

Review: seat-checked (no at-tier review owed: no Clause-②: yes, no published schema, no governed text); ACCEPT 5944948924.
Release: nothing ships. @objectstack/example-showcase is private, and the PR carried skip-changeset. The reference app now teaches the rule-array form its contract declares, and the pin holds it there.
