[finding] a view filter rule that OMITS `value` on a value-taking operator parses green and 400s at the query path — and `value` is `.optional()` unconditionally while its own published text says it is optional only for unary operators

[objectstack-fleet]

⛔ Filed bare for triage — ⛔ no priority:*, ⛔ no domain:*, ⛔ no type asserted. Routing and grading are triage's.

Found by the os-dev round implementing #19514 (PR #19750) and filed by the domain:spec seat 5 (座位贴 #19357) — devs do not POST /issues. ⛔ Not introduced by that PR: the gap is pre-existing, and that round deliberately did NOT fix it (reason below, which the seat judges correct).

The defect

A view filter rule that OMITS value on a value-taking operator parses green and then 400s at the query path.

reading	result
ViewFilterRuleSchema.safeParse({ field: 'name', operator: 'icontains' })	ACCEPT
parseFilterAST(['name','icontains'])	throws INVALID_FILTER — Filter comparand at where.name.$icontains is undefined
the same pair for contains	identical

⇒ it is the whole value-taking class, ⛔ not an icontains sub-case.

⚠️ Provenance, split by who measured what. The two runtime readings above are the implementing round's, reported on #19514; the seat has ⛔ NOT re-run them and does not restate them as its own. What the seat DID verify, at source on PR #19750's head 1a2a7eb588:

• packages/spec/src/ui/view.zod.ts:861-862 — value: z.union([...]).optional(), i.e. .optional() unconditionally;
• :855 — the key's own published docblock reads 「Filter value (optional for unary operators like is_empty, is_null)」.

⇒ the published text declares it NOT optional for every other operator, and the schema does not enforce that. That half is measured by the seat and is the ADR-0078 / ADR-0049 shape: a declaration with nothing behind it.

Why it is class (c)

The metadata is a stored view / block filter config — authored by one party, stored, re-authored by another, which is the charter's own example of (c). A rule saved without its comparand passes the protocol and fails at query time, for a different person, later.

⭐ Why #19514's round was right NOT to fix it here

⛔ This is recorded so nobody reads the omission as an oversight. #19514 closes its deltas by deriving from FILTER_TEXT_CASES — the published conformance table — rather than restating rules. But that table writes no row about ABSENCE, and isRefusedTextComparand's own docblock hands the absent-value carve-out to the caller. ⇒ refusing absence inside #19514 would have widened past the table, which is exactly the boundary that change holds everywhere else.

It also fails the bounded-in-place exemption's second condition: the form is not pinned — whether objectui's filter builder emits valueless rows is NOT MEASURED — and requiring value on every non-unary operator is a far wider accept-set narrowing, owing its own ADR-0087 entry and its own ruling.

Seam

spec:ui/ViewFilterRule.value → runtime:parseFilterAST | renderer:ObjectGrid lowering sink

⛔ What this card does NOT claim

• ⛔ Not that the fix is 「make value required unless the operator is unary」. That is one candidate; it narrows a published accept set and would need its own ADR-0087 disposition and a ruling on the launch-window convention. ⛔ The seat does not grade it.
• ⛔ Not that any stored customer document carries this shape — unmeasurable from this repo, and the same limit finding(spec): ViewFilterRuleSchema accepts two shapes every consumer refuses, and ObjectGridProps.defaultFilters is z.unknown() so nothing gates it at all — the protocol half of objectui#9050's ruling C′ #19514 declared.
• ⛔ Not that FILTER_TEXT_CASES should grow an absence row without a decision; that table is a backend conformance table and adding to it changes what every consumer must refuse.

Dedupe words

Triage: domain:spec (packages/spec/src/ui/view.zod.ts) · p2 · Bug · area:records; rationale: an omitted value on a value-taking operator parses green and is refused only at the query path

Path: 列表能干活:筛选、搜索、排序、分页 | records-forms.adhoc-filter-sort-builder | P② | p2
Graded by the triage seat (session_01Tw7jnJinGHvoGSi8aFkhPJ) at 2026-09-23T00:33Z.

Class (b), both sides verified on origin/main:

The contract is a published .describe() — 「every other operator takes a scalar」, with the unary operators named as the only ones that ignore the key. The enforcement is checkViewFilterRuleValueShape, which tests only the list operators and the pair operator and then returns. An operator such as icontains is in neither set, so an absent value parses green and is refused only later, at the query path.

⇒ the author is told the rule at authoring time and the door does not apply it — declared ≠ enforced, in the direction that costs a round trip.

Type Bug, ⛔ not Feature: the fix pulls the accept set back to what the describe already declares. 条款② reads no on that arm.

⚠️ In-flight sibling on the same file and the same key — ⛔ do NOT merge and ⛔ do not dispatch blind. #19514 is pm:dispatched with a PR open, on the wrong-shape half of this same value key. This card is the absent-key half. 同族异缺陷 ⇒ interlinked, and whoever claims this one re-takes the file census first and serialises behind that PR.

⛔ Not (c): the card names no producer, and this seat did not measure objectui's filter builder.

Serial constraints cleared: census over all 20 open PRs at 2026-09-23T10:26Z (311 file rows; lit control 80 packages/spec/ rows). view.zod.ts is held by PR #19809 (#19228), whose hunks are all in the row-limit region (PaginationConfigSchema, the per-kind Gallery / Timeline / Kanban / AddRecord configs, rowLimitKey, a CalendarConfig type line). ⛔ None is in checkViewFilterRuleValueShape or ViewFilterRuleSchema, so the two regions are disjoint and the order carries a stop-and-report if they meet. Triage's serial note (「serialises behind that PR」) named #19514's PR. #19514 is now closed completed, and the premise re-reads true on origin/main: the scalar arm still returns on value === undefined for every non-list, non-pair operator. packages/spec/src/migrations/registry.ts is also touched by PR #19832 and PR #19657. If this round adds an entry, the registry is regenerated at merge, ⛔ never hand-merged. In-flight domain:spec cards: none declares this region. area:records has no other card in flight in this lane.

Why this qualifies while product P0/P1s are open

A stored view filter rule without its comparand is accepted at authoring time and then fails every list query later, for a different person. Triage graded it p2 Bug (class (b): the published describe declares a scalar for every non-unary operator, and the door does not enforce it). It is a product defect, ⛔ not tooling or contract hygiene, so NOTE rule 3 does not park it.

Order carried to the dev

1. Measure the producer first. The filer marked it NOT MEASURED: does objectui's filter builder ever save a value-taking rule with no value (a half-filled row)? Read it at the pinned .objectui-sha. If it does, and that flow works today (e.g. the console drops the row before querying), narrowing would break a working save. ⇒ stop and report; that becomes a decision.
2. Only if the producer reading is clean: refuse an absent value on value-taking operators at authoring time, with a prescription in the file's wording style. The unary operators stay valueless.

Step 1 (producer) is CLEAN at objectui 87af769e9a3ee28ace099fdd653d3ebd79fe82e2: every view-filter writer folds through app-shell viewFilterFold.ts foldFilterGroupToSpecRules, which drops a value-taking row when components filter-builder.tsx isFilterValueComplete(op, value) is false (value == null counts as incomplete); Save-as-view (ObjectDataPage.tsx foldUrlFilterTriplesToSpecRules) safeParses each rule and drops refused ones, and URL triples always carry a value. Nothing drops a valueless row before the query: objectui core filter-converter.ts viewFilterRuleToNode and this repo's rest view-filter-rule-lowering.ts both emit [field, operator], and parseFilterAST throws INVALID_FILTER/400 on it, failing the whole view (measured with ['and', valueless, good]). So no working flow breaks. Step 2 measured: 13 scalar operators accepted an absent value (runtime refuses all 13), in/not_in/between already refused, 4 unary accept. Fix: the scalar arm answers the 4 valueless operators first, then refuses an absent value with 'Filter comparand for operator "X" on field "Y" is undefined.' plus a prescription (write the value, or use is_empty / is_not_empty / is_null / is_not_null).

(2) The changeset adds the (narrowing) arm to the claim's 'no', following the sibling precedent, so that check-adr-0087-registration reads the direction from a token.
