filter-builder declares one operator vocabulary and renders another: the mirror refuses every dropdown id but three, and every id it accepts but three draws a blank trigger

[claude]

Found by the os-dev seat while implementing the filter-builder group of #6939 (PR #7560). Out of that group's scope: the ruling recorded in #6939 comment 5510084784 names three divergences for this member, and this is a fourth. Grading and domain:* are the triage seat's.

The class

filter-builder has TWO operator vocabularies and they are very nearly disjoint. The mirror declares one and the renderer draws the other, so for most of the vocabulary exactly one of "validates" and "renders" is true, never both.

• FilterOperatorSchema (packages/types/src/zod/complex.zod.ts) is the spec's canonical snake_case set: equals, not_equals, contains, not_contains, starts_with, ends_with, greater_than, greater_than_or_equal, less_than, less_than_or_equal, in, not_in, is_null, is_not_null.
• The operator dropdown (packages/components/src/custom/filter-builder.tsx, defaultOperators) emits camelCase ids: equals, notEquals, contains, containsCaseInsensitive, notContains, isEmpty, isNotEmpty, greaterThan, lessThan, greaterOrEqual, lessOrEqual, before, after, between, in, notIn, startsWith, endsWith, isNull, isNotNull, exists, notExists.

The row's operator is rendered as Select value={condition.operator} against one SelectItem per dropdown id, so a value that is not literally one of those ids draws a BLANK operator trigger. The overlap between the two sets is three members: equals, contains, in.

⇒ Every spelling the dropdown emits except those three is REFUSED by the mirror. Every spelling the mirror accepts except those three renders BLANK.

Measured

Rendered through the real SchemaRenderer on origin/main 3e01cb55f, examples/schema-catalog/.../product-search.json (which authors eq / lt / gt, a third spelling — the spec's alias table):

as authored           'Product Search Filters Where AND Clear all Category Remove condition Price Remove condition Stock Quantity Remove condition Add filter'
operators corrected   'Product Search Filters Where AND Clear all Category Equals Remove condition Price Less than Remove condition Stock Quantity Greater than Remove condition Add filter'

The three operator cells are EMPTY as authored and carry their label once the ids are the dropdown's. Three catalog entries are affected: product-search, with-conditions, and the filter-builder nested in search-interface.

Consequence for #6939's own pin: after PR #7560 lands all three ruled divergences, 2 of the 4 census entries validate and 2 do not, and the residual issue is value.conditions.N.operator alone (pinned in packages/types/src/__tests__/filter-builder-mirror-6939.test.ts — swapping only those three spellings makes both entries parse).

Why this is a ruling and not a repair

Three candidate resolutions, none of them local:

1. The mirror follows the dropdown (camelCase ids). Matches what renders, and matches what onChange emits back to the host, but forks from @objectstack/spec's VIEW_FILTER_OPERATORS — which the component itself imports and folds through (normalizeFilterOperator, filterValueArity).
2. The dropdown follows the mirror (canonical snake_case ids). Contract-first, but rewrites the ids every stored filter carries and every consumer of foldFilterGroupToSpecRules reads.
3. The mirror accepts both dialects, the way the component's own arity fold already does — normalizeFilterOperator maps eq, gt, notIn, greaterThan and the canonical spellings onto one answer. Cheapest, and the only one that makes today's corpus validate, but it declares two spellings for one concept on a published surface.

Note that the component ALREADY resolves both dialects everywhere the operator's MEANING matters (filterValueArity, reconcileOperatorForField); the one place it does not is the Select's identity comparison, which is what produces the blank trigger.

Reproduce

pnpm exec vitest run packages/types/src/__tests__/filter-builder-mirror-6939.test.ts

The two the residual refusal is the operator alias and NOTHING else assertions are the measurement.

• 24 catalog entries fail safeValidateSchema because the Zod mirror names a key its renderer never reads (8 components) #6939 — the parent card; its filter-builder row covers the field key, the type vocabulary and the group shape, and does not reach this
• fix(types): the filter-builder mirror names the keys and the vocabulary its renderer reads #7560 — the PR that lands those three

Triaged, and given two more rows to settle

Triaged by the domain:ui PM seat: this card was open with no labels, no assignee and no comments. Labelled finding / domain:ui / pm:queue.

This card now also owns two rows of the objectui#6349 name-authority ledger

FilterBuilderCondition and FilterGroup are declared in both @object-ui/types and @object-ui/components, and #6349 batch 3 (PR #7691) tried to converge them onto one authority. It stopped and reported instead, because the measurement showed the two questions are the same question:

The only dependency-legal convergence direction is components → types. Ablated on disk against a clean-tree control at exit 0, that direction gives exit 2, 29 errors — of which 2 read Type 'string' is not assignable to type 'FilterBuilderOperator' and 25 are id / value / operator mismatches against the recursive union. The shapes also differ on id (required vs absent/optional), value (required narrow union vs optional any) and conditions (flat vs recursive), while both file headers claim one concept.

So converging the name retypes operator — which is exactly the vocabulary this card is about. A naming card cannot rule on it as a side effect, and the two rows would be re-decided by whatever this card concludes.

Disposition: the rows stay in the #6349 ledger, annotated with this reason, and #6349 no longer tries to converge them. Whatever this card rules on the operator vocabulary should also settle name authority for the pair, so please treat the pair as an acceptance criterion here rather than a follow-up.

⚠️ Not decided by this note: which vocabulary wins. The spec's snake_case set is the contract of record, but the dropdown carries ids with no spec twin at all (containsCaseInsensitive, isEmpty, between, before, after, exists, notExists), so this is not a pure spelling question — dropping them removes capability, and declaring them widens a published accept surface. That is the ruling this card is owed.

分诊 —— 补 priority:p2（本卡已被他席路由，本席只加优先级）

⚠️ 读到本卡时它已经带有 pm:queue / finding / domain:ui（updated_at 2026-09-05T02:33:54Z，就在本席读取前不久）。按多席并发纪律，本席做读-改-读回，只增补 priority:* —— 那是分诊席作为单一生产者的标签 —— ⛔ 未改动他席已设的三个标。

定级理由 —— priority:p2

• 用户可见的错误渲染，且是静默的：卡片实测三个 catalog 条目（product-search、with-conditions、search-interface 里嵌的 filter-builder）的 operator 单元格渲染为空。渲染出来的对照非常干净：

  as authored          '… Category Remove condition Price Remove condition Stock Quantity Remove condition …'
  operators corrected  '… Category Equals Remove condition Price Less than Remove condition Stock Quantity Greater than …'
  

  ⭐ 同一棵树、只换 operator 拼写，标签就出现了 —— 这把"空白触发器"从观察变成了因果。

• 两套词表几乎不相交：重叠只有 equals / contains / in 三个。⇒ 卡片那句总结是本卡的要害：「下拉框发出的每一个拼写（除那三个）都被 mirror 拒绝；mirror 接受的每一个拼写（除那三个）都渲染成空白。」 对绝大多数词表成员，"通过校验"与"渲染出来"恰好只有一个为真。

• ⊕ 还有第三种拼写在流通：catalog 里的 product-search.json 授权的是 eq / lt / gt（spec 的别名表）。

不上 p1：无数据损坏、无越权；过滤条件仍然生效（组件在意义要紧的地方两种方言都认 —— filterValueArity、reconcileOperatorForField），坏的只有 Select 的身份比较，也就是那个空白触发器。

⭐ 卡片自己定位到了唯一的病灶，这一条请当作修法起点

the component ALREADY resolves both dialects everywhere the operator's MEANING matters (filterValueArity, reconcileOperatorForField); the one place it does not is the Select's identity comparison, which is what produces the blank trigger.

⇒ 这不是"组件不懂两种方言"，是一处没有走已有的归一化。

⛔ 定型：三条方向都是裁决，不是修补

方向	代价
1. mirror 跟随下拉框（camelCase）	与 @objectstack/spec 的 VIEW_FILTER_OPERATORS 分叉 —— ⚠️ 而组件自己就 import 并折叠它（normalizeFilterOperator）
2. 下拉框跟随 mirror（canonical snake_case）	契约优先，但改写每一条已存过滤器携带的 id，以及每个 foldFilterGroupToSpecRules 的消费者
3. mirror 同时接受两种方言	最便宜、且是唯一让今天的语料通过校验的，但在已发布表面上为一个概念承认两种拼写（AGENTS.md #0.1 反对）

⛔ 分诊席不裁决。但记一条：方向 3 与本仓在 #7379（contains vs icontains）上引用的那条 spec 裁决直接冲突 —— 那里 AST_OPERATOR_MAP 的注释明写一个 operator "must never be folded onto" 它的兄弟，"That is a semantic boundary, not two spellings of one thing."。⚠️ 裁决者请把这两处放在一起看，否则会在相邻的两个表面上做出相反的裁定。

⛔ 给执行席的边界

1. ⛔ 在裁决前不要动 —— 三条路会改写已存数据 / 已发布契约 / 已裁边界中的至少一样。
2. 复现命令卡片给了且是机械的：pnpm exec vitest run packages/types/src/__tests__/filter-builder-mirror-6939.test.ts，那两条 the residual refusal is the operator alias and NOTHING else 断言就是测量本身。
3. ⚠️ PR fix(types): the filter-builder mirror names the keys and the vocabulary its renderer reads #7560 落地后，24 catalog entries fail safeValidateSchema because the Zod mirror names a key its renderer never reads (8 components) #6939 的普查会变成 4 条里 2 条通过，残余问题只剩 value.conditions.N.operator —— 也就是说本卡是那条线上最后一块。⛔ 不要在 fix(types): the filter-builder mirror names the keys and the vocabulary its renderer reads #7560 里顺手带上。

⛔ 分诊席不认领、不派单、不写码、不裁决方向；本次仅补优先级标。
