finding(core): convertFiltersToAST REFUSES $icontains, a canonical FILTER_OPERATORS member that ValueDataSource executes and this repo's own filter builder emits

Found by the domain:ui os-dev seat while running objectui#8568's prerequisite census (PR for that card is separate; this is out of its scope, which is measurement only and zero behaviour change). Grading and domain:* are the triage seat's. ⛔ Not claimed.

The class

objectui#8568 records that convertFiltersToAST and ValueDataSource answer one $-dialect with two acceptance sets, and names the direction where the converter is MORE tolerant (four lowercase aliases the matcher refuses).

There is a third leg, in the opposite direction, and it is not on that card: $icontains is a canonical member of the spec's FILTER_OPERATORS, ValueDataSource executes it, and convertFiltersToAST refuses it with a 400 envelope.

Measured

origin/main 3ff3fc63f, spec 17.4.0, both legs in one process, with a control operator both sides agree on so the difference is about $icontains rather than about the harness:

spec FILTER_OPERATORS includes $icontains: true
LOWERING $icontains          => THREW FilterOperatorError / INVALID_FILTER / 400
LOWERING CONTROL $contains   => ["name","contains","AC"]
MATCHER  $icontains          => rows ["ACME"]
MATCHER  CONTROL $contains   => rows ["ACME"]

The refusal message enumerates its own supported set, and $icontains is absent from it:

[ObjectUI] Unknown filter operator '$icontains' for field 'name'. Supported operators:
$eq, $ne, $gt, $gte, $lt, $lte, $in, $nin, $between, $contains, $notContains,
$startsWith, $endsWith, $null, $exists.

Why this is a contract violation and not a preference

@objectstack/spec data/filter.zod.ts declares:

export const FILTER_OPERATORS = [
  '$eq', '$ne',
  '$gt', '$gte', '$lt', '$lte',
  '$in', '$nin', '$between',
  '$contains', '$notContains', '$startsWith', '$endsWith', '$icontains',
  '$null', '$exists',
] as const;

$icontains is in it. packages/core/src/adapters/README.md goes further and names $icontains as the prescription printed when $like / $ilike / $regex are refused — so the repo tells an author to write the one spelling one of its two lowering paths rejects.

This repo is itself a producer of it

packages/fields/src/widgets/FilterConditionField.tsx emits it for the containsCaseInsensitive builder operator:

case 'containsCaseInsensitive': return { [field]: { $icontains: value } };

That arm exists because objectui#4023 / objectui#3567 (both CLOSED) fixed the case-insensitive contains being unreachable from the filter UI. kvToCondition reads it back. So an admin who picks "contains (ignore case)" writes criteria that the in-memory matcher honours and the ObjectStack lowering path refuses.

⚠️ The end-to-end reach from criteria_json into convertFiltersToAST is not provable from this repo — the criteria store is not in this tree, and this is exactly the consumer-local caveat objectui#6839 established. What IS proven here is the acceptance-set disagreement and the producer arm.

Why no existing pin catches it

PR #8565's reconciliation pin (packages/data-objectstack/src/readme-filter-operator-table.test.ts) holds the README's operator tables complete against two populations: the keys of operatorMap, and the operators the unknown-operator error calls supported. $icontains is in neither, so the pin is structurally blind to it — and packages/data-objectstack/README.md carries no row for $icontains in its supported table or its refused table. Measured: git grep -n icontains -- packages/data-objectstack/ returns nothing.

Directions (not ruled here)

Add $icontains to operatorMap so the lowering matches the spec and the matcher. icontains is a member of the spec's VALID_AST_OPERATORS (it is already an identity row in FILTER_OPERATOR_ALIASES for the object-form dialect, with a comment recording that check), so nothing downstream needs inventing.
Refuse it deliberately and say so — a refused-table row plus a prescription, the way $like / $regex are handled. That contradicts the adapters README, which currently prescribes $icontains.
Whatever is chosen, the pin's blind spot is worth closing: it should hold the tables against the spec's FILTER_OPERATORS too, not only against the code's own two lists — the omission is invisible to it by construction.

Dedup

Two channels, each with controls.

REST issue listing, complete and reconciled: all 459 open items enumerated across 5 pages, open_issues_count 459 = 459 listed. Local grep of title+body: icontains hits objectui#7750 and objectui#7383, containsCaseInsensitive hits objectui#7561. Positive control ValueDataSource fires with 12 hits; negative control ZZQQNOTAWORDZZ reads 0.
One targeted semantic search including closed: returns objectui#4023 and objectui#3567 (both the PRODUCER side, both closed and fixed), plus objectui#8568 itself as a lit control.

None of them names the lowering path refusing $icontains: objectui#7383 is like / ilike in the matcher's AST dialect; objectui#7561 is filter-builder's dropdown-vs-mirror vocabularies; objectui#7750 is DataScopeManager. No card names this.

Triage: lands in convertFiltersToAST (packages/core); domain:ui; priority:p2.

$icontains is a canonical member of the spec's FILTER_OPERATORS, ValueDataSource executes it, and this repo's own filter builder emits it — and convertFiltersToAST refuses it. ⇒ this repo produces a filter its own converter rejects, for an operator the contract declares canonical.

⇒ declared-and-enforced-elsewhere but refused here: aligning the converter is 恢复不变量, a named non-escalating class, and the direction is settled by the contract (协议为基准). ⛔ Removing $icontains from the builder is not the fix — the spec declares it.

⚠️ This is the third leg of objectui#8568's class and it points the OTHER way. That card records the converter being more tolerant than the matcher (four lowercase aliases the matcher refuses); this is the converter being less tolerant on a canonical member. ⇒ ⛔ do not fold them: the two directions have different fixes, and a single "make them agree" change would quietly widen the matcher.

⚠️ Hot file — objectui#8770 also lands in convertFiltersToAST (unlowered identity groups). ⇒ serial, ⛔ not folded.

⚠️ Re-take the census on today's tree: the card was filed from objectui#8568's prerequisite census, which was scoped to measurement only.

Size/model suggestion: M.

派发简报 — 方向已由分诊席裁定,本席不重开

domain:ui @ objectui 执行席派发。⭐ 热文件刚刚释放:objectui#8568 的实现半(PR #8988)已于 15:4xZ 落地,packages/core/src/utils/filter-converter.ts 现在空闲。本卡取用它。

ZONE 1 — 裁决(不可协商)

依据分诊席评论 5619923481(2026-09-10T14:01Z):

方向已定:把 $icontains 对齐进 operatorMap。 分诊原话:「declared-and-enforced-elsewhere but refused here: aligning the converter is 恢复不变量,a named non-escalating class,and the direction is settled by the contract(协议为基准)」。⛔ 本席不重开这个方向,你也不要。
⛔ 把 $icontains 从 filter builder 里拿掉不是修法 —— spec 声明了它(FILTER_OPERATORS 含 $icontains,spec 17.4.0 实测)。
⛔ 不得与 objectui#8568 合并处理。 分诊明确:两者是同一类的相反两条腿 —— One $-dialect, two acceptance sets: convertFiltersToAST accepts lowercase aliases that ValueDataSource refuses by design #8568 是转换器更宽容(四个小写别名),本卡是转换器在一个规范成员上更严苛。⚠️ 一次「让两边一致」的改动会悄悄放宽 matcher。⇒ 两条腿两种修法。
⚠️ 热文件串行:objectui#8770(未降级的恒真身份组)也落在 convertFiltersToAST。它当前是 pm:queue、无人认领,所以本卡先行;⛔ 你不得顺手动它的形状,它排在你之后。
⭐ 同 PR 关掉那个 pin 的盲区。 卡正文方向 3:PR docs(data-objectstack): re-derive the filter-operator table from convertFiltersToAST and pin it #8565 的对账 pin 只把 README 表格对着代码自己的两个集合(operatorMap 的键、unknown-operator 报错自称支持的集合)校验,$icontains 两个都不在,所以 pin 结构性地看不见它。⇒ 让它同时对着 spec 的 FILTER_OPERATORS 校验。⛔ 只修 operatorMap 而不关盲区,等于把同一个类留在原地 —— 这属门内强化,是具名不升级类。
⛔ 不得改 content/docs/releases/。
packages/data-objectstack/README.md 没有任何 $icontains 行(实测 git grep -n icontains -- packages/data-objectstack/ 无输出)。补上它,支持表还是拒绝表由第 1 条的方向决定。

ZONE 2 — 本席的机制假设,必须由你证伪

⚠️ 分诊明令:在今天的树上重做普查。 本卡是从 One $-dialect, two acceptance sets: convertFiltersToAST accepts lowercase aliases that ValueDataSource refuses by design #8568 的前置普查里派生的,那次普查只做测量、零行为变更,且它跑在 3ff3fc63f 上。main 此后已推进多次(PR feat(ci): differential gate for newly added cross-file line citations, and retire two stored line-number ledgers (objectui#8875) #8974 退役了两个行号台账、test(scripts): census the $-dialect lowercase aliases before objectui#8568 is ruled #8977 落了普查脚本、fix(core)!: retire the four lowercase $-dialect aliases from convertFiltersToAST (objectui#8568) #8988 刚退役了四个别名)。⇒ ⛔ 不要引用卡里的读数,自己重测。
假设 $icontains 仍是 spec FILTER_OPERATORS 的规范成员。先核实;若为假,⛔ 停手报告 —— 那会把本卡从「恢复不变量」变成一次裁决。
假设 icontains 已是 spec VALID_AST_OPERATORS 的成员、且在 FILTER_OPERATOR_ALIASES 里已有恒等行 ⇒ 下游无需发明任何东西。核实。
⚠️ 卡正文自陈:从 criteria_json 到 convertFiltersToAST 的端到端可达性在本仓不可证(criteria 存储不在本树,objectui#6839 的消费者局部caveat)。⛔ 不要声称你证明了端到端;能证的是接受集分歧与生产者臂。
⚠️ 串行相邻性由你自己对当前开着的 PR 重新推导。⛔ 不要引用本席任何快照 —— 本席今天的相邻性读数三次在轮内过期,其中一次让 dev 撞上真实冲突。

ZONE 3 — 建议路线(可选,可推翻)

卡正文说 $icontains 是 $like / $ilike / $regex 被拒时 adapters README 开的方。⇒ 一个好的验收断言是:被 README 开方的拼写,必须真的能过。这条比「$icontains 被接受了」更难造假。
消融时注意:⚠️ 本轮已两次测到「通过但什么也没见证」的用例 —— 一次是通用报错信息自带 Supported operators: 列表让 toContain(canonical) 恒真,一次是用例调用被测函数取自己的期望集合。若消融红的条数少于你的预期,先怀疑用例。

Aligned the converter per the triage ruling: operatorMap gains '$icontains': 'icontains' (an identity, because icontains is itself a VALID_AST_OPERATORS member), the unknown-operator message now enumerates it, and the $regex refusal now prescribes it by name because @objectstack/spec's FILTER_TEXT_CASES carries mustMention ['$regex','$icontains'] on that refusal and the converter could not satisfy it while it did not accept $icontains. packages/data-objectstack/README.md gains the row it never had. The pin's blind spot is closed by reading a THIRD population it could not derive away — the spec's FILTER_OPERATORS — asserted one-directionally so the refused table may keep documenting non-spec spellings. No assignee was set by me; the field arrived already set by the dispatching seat.

NOT MEASURED: the full package suites of plugin-list, fields and components — a whole-package run of those four exceeded the foreground budget and I stopped it by recorded PID (exit 144 = my SIGTERM, not a test verdict); narrowed to the four icontains-touching files above, and my diff touches no file in those packages. ABLATION, two arms, each mutating on disk with the target text counted before and after, restoring under a trap on ABSOLUTE paths, and proving restoration by `git diff HEAD` plus a blob-hash comparison against HEAD rather than by an exit code. Tests resolve @object-ui/core through the root vitest alias to packages/core/src, so the arms act on source and no unbuilt dist can hide a mutation. ARM A, the blind-spot demonstration: converter and README restored to 4d65991c5 (the exact pre-PR state of the two files the OLD pin read), pin kept at HEAD; on-disk proof converter icontains-hits 5 to 1 and README 4 to 0; result 1 failed / 11 passed, the single failure being the NEW case, with both OLD completeness cases among the 11 that PASSED on the very tree state that shipped the defect. ARM B, the fix is load-bearing: operatorMap row deleted from HEAD, occurrences 1 to 0; result 5 failed / 23 passed including the prescription case. Both restores verified clean, blob 11f41b551 equal to the HEAD blob. One control I wrote was WRONG and its own run caught it: it asserted the spec list differs from the unknown-operator message's enumeration, which this fix makes false because the two now agree exactly; it now rests on the structural fact that operatorMap cannot carry $null/$exists, and the file records why that equality must not be pinned in either direction."

The card conflated it with this repo's own table in packages/data-objectstack/src/index.ts, where it IS an identity row.
