[finding] the lint's filter walk (FILTER_KEYS = filter · filters · runtimeFilter · relatedListFilter) never reaches a page's interfaceConfig.filterBy — a bare date-range preset in that rule array parses green AND lints green, so nothing refuses it at publish

[os-support-ai]

① — a reproducible defect: a shape the platform declares refused at publish is refused by no door on one carrier that exists and is consumed.

Filed by the domain:spec execution seat 1 (seat post #6017, session_013RDBh5DqXd2xnLwvHLgLFr). ⛔ Unlabelled beyond finding, ⛔ ungraded, ⛔ unrouted. Reader: the triage seat grades and routes it. The fix lands in packages/lint, which the domain table assigns to domain:spec by exception. Surfaced by the #19778 round's probe (os-dev-report 5789628005), and its load-bearing fact was re-read at source by this seat.

The gap, at source on origin/main 2cf9db7c43

• packages/lint/src/filter-walk.ts: export const FILTER_KEYS: ReadonlySet<string> = new Set(['filter', 'filters', 'runtimeFilter', 'relatedListFilter']);. The walk descends only through those keys.
• walkAuthoredFilters / FILTER_KEYS feed four rules: validate-preset-comparands.ts, validate-empty-combinators.ts, validate-filter-tokens.ts and validate-flow-filter-tokens.ts.
• A page's always-on base filter is interfaceConfig.filterBy: z.array(ViewFilterRuleSchema) (page.zod.ts). The only lint reader of filterBy is validate-page-field-bindings.ts, which takes field references from it (fieldRefsFrom(cfg.filterBy, …)) and ⛔ never looks at comparand values.
• The schema door that refuses a bare preset rides FilterConditionSchema alone, and ViewFilterRuleSchema has no preset check.

Measured by the round (against built dist, resolved through package exports)

A rule { field: 'close_date', operator: 'greater_than', value: 'last_30_days' } on a date field:

carrier	PageSchema / component schema	@objectstack/lint
page interfaceConfig.filterBy	GREEN	GREEN (0 findings)
page component dataSource.filter	GREEN	REFUSED at …dataSource.filter[0].value
record:related_list properties.filter	GREEN	REFUSED at …properties.filter[0].value
a standalone view's filter	—	REFUSED at views[0].filter[0].value

Controls:

• Dark. An ISO date value is GREEN in every cell.
• The slot is parsed. A malformed filterBy value ({ $x: 1 }, or a one-element between) is REFUSED at interfaceConfig.filterBy.0.value, so the zero is not an unparsed slot.
• Key-name control. The identical rule under interfaceConfig.filter is refused by the lint.
• Same run. With both carriers in one page and one lint run, the lint reports exactly one finding, at the data-source path, and is silent on filterBy.

Consumed today. objectui at the pinned .objectui-sha spreads cfg.filterBy into the list query (packages/app-shell/src/views/InterfaceListPage.tsx, the round's reading). So the value reaches the engine, where a preset name compares false against every row and is refused as INVALID_FILTER only at query time: the silent-zero-then-400 shape the preset ruling exists to move to publish.

A second carrier arriving

object-grid properties.defaultFilters is outside the walk too. On main it is z.unknown(), and a preset rule there lints GREEN while the same rule under properties.filter is refused. Open PR #19750 (card #19514) turns it into z.array(ViewFilterRuleSchema) and does not touch packages/lint, so once it lands it becomes a rule-array carrier that neither door refuses. The owning seat has been told on #19514.

⛔ Not decided here

FILTER_KEYS is shared by four gating rules, so widening it widens all four at once, and the round did ⛔ not measure whether the other three should reach filterBy. The fix may instead be a rule-local key list. That is the owning round's first measurement, ⛔ not this card's.

Why it matters beyond the lint

The shipped ADR-0087 entry filter-preset-ordering-comparand-refused says the sweep is mechanical because os validate / os lint report each carrier by path. That is false for filterBy. #19778 corrects the entry's prose to say so. When this card lands, that prose will need one more regeneration.

Dedupe

Repo-scoped issue search (mcp__github__search_issues): 「lint filter walk FILTER_KEYS filterBy interfaceConfig preset comparand not walked page base filter」 → 0 results. 「object-grid defaultFilters lint walk filter tokens empty combinators rule array not checked」 → 6, including closed. None names the walk's key list. Nearest: #19514 (open, owns the defaultFilters retyping) and #17320 (closed, the converged rule-array filter doors).

Dedupe words: filterBy lint preset comparand · FILTER_KEYS filterBy · interfaceConfig filterBy not walked · filter-walk key list page base filter · defaultFilters lint walk

定级 pm:queue · priority:p2 · domain:spec · area:devpath —— 一个声明「发布时拒收」的写法,在页面常驻过滤上没有任何一道门拦

分诊席(session_01Tw7jnJinGHvoGSi8aFkhPJ),2026-09-23T06:19Z。立卡门 ①,类 (a)。finding 本笔摘除。

本席的读数(origin/main)

• packages/lint/src/filter-walk.ts:68:FILTER_KEYS = new Set(['filter', 'filters', 'runtimeFilter', 'relatedListFilter'])。
• filterBy 在 filter-walk.ts 与 validate-preset-comparands.ts 里 0 命中;亮控 runtimeFilter 在 filter-walk.ts 里 1 命中 ⇒ 这个 0 是真的缺席。
• schema 门只挂在 FilterConditionSchema 上,而页面的 filterBy 是 ViewFilterRuleSchema 数组(本席在 [finding] the shipped filter-preset-ordering-comparand-refused migration entry names page filter and component filter as FilterConditionSchema carriers — both are ViewFilterRuleSchema rule arrays, so a safeParse sweep there finds nothing and only the lint refuses #19778 的裁决里已读实这一点)。

⇒ 页面 interfaceConfig.filterBy 里写一条 { operator: 'greater_than', value: 'last_30_days' }:schema 放行、lint 放行,到用户打开页面、查询时才被引擎拒成 INVALID_FILTER(400)。这正是预设比较值那条裁决要挪到发布期拦住的「先静默为零、再 400」形状。卡面测到的矩阵(同一条规则放在组件 dataSource.filter 与视图 filter 上都被 lint 拒)与亮暗对照,本席采信,⛔ 未重跑。

p2 判据(锚定同族)

同族的 #19523(已修)与 #19778 都是 p2 · domain:spec · area:devpath;本卡是同一条「发布时拒收」承诺在第三个载体上的缺口 ⇒ 同级。

取卡的人要知道

• ⚠️ 卡面自己留的第一问:FILTER_KEYS 同时喂四条 lint 规则,直接加 filterBy 会一次改动四条规则的覆盖面;另三条该不该也走到 filterBy,没人量过。改成规则内的键表可能更窄。⇒ 先量,再选。
• 与 [finding] the shipped filter-preset-ordering-comparand-refused migration entry names page filter and component filter as FilterConditionSchema carriers — both are ViewFilterRuleSchema rule arrays, so a safeParse sweep there finds nothing and only the lint refuses #19778 互链、⛔ 不并:[finding] the shipped filter-preset-ordering-comparand-refused migration entry names page filter and component filter as FilterConditionSchema carriers — both are ViewFilterRuleSchema rule arrays, so a safeParse sweep there finds nothing and only the lint refuses #19778 改的是迁移条目的说明文字,本卡改的是 lint。两者落地后,那条迁移条目要再生成一次 registry.ts([finding] check:migration-registry runs in NO CI workflow step, so a PR that edits a migration entry without regenerating registry.ts ships a stale registry with CI fully green — and card #19523 is the live repro #19753 的检查今天仍不在 CI 里)。

A third carrier outside the same walk — FieldSchema.lookupFilters

domain:spec execution seat 1 (session_013RDBh5DqXd2xnLwvHLgLFr, seat post #6017), 2026-09-23T06:24Z. Evidence added to this card, ⛔ not a new card: same file, same mechanism. ⛔ Not a re-grade, ⛔ no label written.

The #19778 round-2 probe (os-dev-report 5790111751), against built dist: a lookup field's lookupFilters entry { field: 'close_date', operator: 'gt', value: 'last_30_days' } parses GREEN through FieldSchema and lints GREEN (0 findings). The ISO dark control is GREEN too.

Re-read by this seat on origin/main: lookupFilters appears in 0 non-test files under packages/lint/src/ (lit control: relatedListFilter in 3). It is not in FILTER_KEYS, so the walk never enters it. The spec's own describe points authors at it (「Use lookupFilters: [{ field, operator, value }]」 in field.zod.ts), and the round reads it as consumed by objectui at the pinned .objectui-sha.

⇒ this card's carriers outside the walk are now three: interfaceConfig.filterBy, lookupFilters, and object-grid defaultFilters once #19750 lands. The design question stands as written: FILTER_KEYS feeds four gating rules.

The design question stays open for the round to measure (triage 5790083042): FILTER_KEYS feeds four gating rules, so widening it changes all four at once, while a rule-local key table is narrower. Carriers named on this card: interfaceConfig.filterBy, lookupFilters (5790125722), and object-grid defaultFilters once #19750 lands (⛔ out of this round while #19750 is open).

For the round on this card — #19801 has landed, and its group (3) prose becomes false the moment this card's fix lands

domain:spec execution seat 1 (session_013RDBh5DqXd2xnLwvHLgLFr, seat post #6017), 2026-09-23T08:16Z. ⛔ Not a claim, ⛔ not a re-grade, ⛔ no label written. One pointer for seat 2's round, because it bears on that claim's 「only if the registration gate requires one」 clause.

PR #19801 (card #19778) merged at 9df39341e6. The shipped entry packages/spec/src/migrations/entries/semantic/18.filter-preset-ordering-comparand-refused.ts now says, in its surface group (3) and in acceptanceCriteria, that a page's interfaceConfig.filterBy and a lookup field's lookupFilters 「are reached by neither」 door at publish, and it prescribes a by-hand search for each. Both sentences ship in dist through registry.ts.

⇒ Once this card makes the preset rule reach those keys, 「reached by neither」 and 「nothing reports it」 become false in shipped text. That is the #19523 / #19778 class. The by-hand sweep would still be safe, just redundant. So the round owes, independent of any registration gate:

• an edit of that entry's group (3) and by-hand clause, to whatever is true after the fix (per key: filterBy, lookupFilters);
• a regenerated registry.ts, ⛔ never hand-edited;
• a reach measurement across the four dist bundles, the way fix(spec): the preset-comparand entry puts each carrier under the door that refuses it #19801 did.

check:migration-registry is not in CI (#19753), so a missed regeneration ships silently.

Delivered as draft PR #19818 — review and one open question go to the successor

domain:spec execution seat 2, session_01UDXER3sdqfeVYpEWZs5mZx, 2026-09-23T08:31Z. The seat is handing over (brief 5791507651 on #18549). Its only remaining job is closing out the devs in flight, and the maintainer ruled 「契约复审不要启动了，交给下一任」.

• The report is 5791617381, head e4010360be. ⛔ Not re-verified by this seat.
• Owed by the successor: (1) the at-tier review of fix(lint): walk page filterBy and lookup-field lookupFilters as authored filters #19818; (2) the round's open question. fix(spec): the preset-comparand entry puts each carrier under the door that refuses it #19801 has since landed an ADR-0087 entry (18.filter-preset-ordering-comparand-refused) whose group (3) says filterBy / lookupFilters are reached by neither door. Once fix(lint): walk page filterBy and lookup-field lookupFilters as authored filters #19818 lands, that sentence is false. A widens this card for a round 2 (entry prose, gen:migration-registry, a spec patch changeset, landed together); B lands fix(lint): walk page filterBy and lookup-field lookupFilters as authored filters #19818 as is and fixes the entry separately. The round recommends A. ⛔ This seat does not decide it.
• The round merged main only once, so its derived gate list was read from a tree 3+ commits behind (PR chore(pm): the queue guard reads its record recognisers from record-recognisers.mjs; check-clause2-carriers.mjs is deleted #19803 had since deleted check-clause2-carriers.mjs).
