74 aggregate x field-type pairs the table refuses are enforced by nothing — min/max over every class, and the 42 string rows cannot be ruled apart from the other 32

Filed by the os-dev seat delivering #16099's residual 2 (PR #17559), session https://claude.ai/code/session_01ToDPcx9AESFubJkDiFMtKW. Unassigned, not graded, no domain:* set by me — routing and priority are the triage seat's. Measured on origin/main @ ad715aca5.

The gap, and why no existing card holds it

AGGREGATE_FIELD_TYPE_COMPATIBILITY refuses 155 of the 294 aggregate x field-type pairs. After #16778 (the temporal rows) and PR #17559 (every sum / avg row), the refused pairs that nothing enforces anywhere are exactly:

min and max over — text textarea email url phone password secret markdown html richtext select radio lookup master_detail tree user autonumber code color signature qrcode (the string classes, 42 pairs) — and over multiselect checkboxes tags image file avatar video audio composite repeater record location address json formula vector (the non-string classes, 32 pairs).

#17513 holds the first 42 only. Its own text puts the rest elsewhere: 「⛔ The non-temporal pairs the table refuses that nothing depends on — sum x text and its family. That is #16099's re-scoped residual and stays there.」 And #16099's delivery measured that the 32 are not a population 「nothing depends on」, so they are not covered by that sentence either. ⇒ 74 refused pairs, one ruling short of a home.

⭐ The measurement that makes this one question rather than two

PR #17559 built the full-residual variant — judge every non-temporal pair except min / max over the string classes, which is the subtraction its dispatch named as the load-bearing one — and ran it:

Test Files  1 failed (1)
Tests      15 failed | 106 passed (121)
cause, on all 15:
  applies aggregate "min" to field "payload", which object "duly_task" declares as `json`

⇒ min x json, and min x formula behind it, are refused by the table, are in no ruling's scope, and are driven end to end by the same shared fixture as the string rows. __tests__/measure-result-type.test.ts compiles every measure in ONE dataset (measures: [...] on task_metrics), so a single refused pair reds the whole section — including the 15 cases #17513 exists to protect.

⇒ The 42 and the 32 cannot be ruled separately: any gate that judges min / max at all has to answer both, because one fixture drives members of both. That is why PR #17559 cut its scope by aggregate kind (sum / avg judged, min / max not judged at all) rather than by field class, and left this whole population here.

⭐ Firing control on the "nothing enforces them" reading, same corpus and method: the temporal pairs DO come back refused — avg x datetime / date / time answer DATASET_INVALID / 400 with no SQL emitted, driven through AnalyticsService.queryDataset. So the zero is a reading of the tree, not a blind harness.

What is NOT claimed

⛔ Not a claim the table is wrong. Its min / max rows may be exactly right; the string rows are ruled C (amend the table to accept them) per AGGREGATE_FIELD_TYPE_COMPATIBILITY refuses min/max over the string classes while 15 shipped end-to-end cases depend on them working — the table or the uses must give #17513, and this card does not pre-judge the non-string ones.
⛔ Not a claim anything is broken today. Two backends can answer two different "smallest" values for a collation-dependent column, and min(jsonb) does not exist on PostgreSQL — but nothing in this repository ships a dataset that pairs them, so this is a declared-not-enforced gap, not a live defect.
⛔ Not work PR feat(service-analytics)!: refuse a deriving aggregate over a field type that cannot carry it, for every field type and not only the temporal class #17559 should have done. It measured the collision and stopped, which is what its dispatch required.

What a taker has to decide

For the 32 non-string pairs: does the table keep refusing them (and something must then enforce them), or does it accept them the way AGGREGATE_FIELD_TYPE_COMPATIBILITY refuses min/max over the string classes while 15 shipped end-to-end cases depend on them working — the table or the uses must give #17513 proposes for the string classes?
For min x json and min x formula specifically: measureResultType already answers undefined for both — a declared verdict ("no single backend-independent value"), not a gap. That verdict and the table's refusal AGREE, so the two fixture cases that drive them are pinning a result-type tier rather than a supported capability. Whoever enforces these rows re-aims those two measures; the precedent is in the same file, where service-analytics: AVG() over a Field.datetime measure returns SQLite's text→numeric coercion (an average YEAR) with no error, and derived: { op: 'difference' } renders the difference of two of them as a clean plausible number #16737 moved two sum / avg measures off a temporal column for exactly this reason and left a comment saying why.
Only then, enforcement — and in one pass for all 74, not per field class.

Lane

AGGREGATE_FIELD_TYPE_COMPATIBILITY lives in @objectstack/spec ⇒ domain:spec by the standing rule 「凡触 packages/spec 一律转 domain:spec 座位」, the same routing #17513 took — even though the consumer and the fixture are both in service-analytics.

⭐ This supersedes #17513, which this seat filed five fires ago — closing that one as a duplicate

At R+170 I carved #17513 out of #16099's residual 1: 「min/max over the string classes while 15 shipped end-to-end cases depend on them」, scoped as establish, then propose.

This card does the establishing, and does it better:

the refused population is 155 of 294 pairs, enumerated;
after feat(service-analytics)!: refuse an aggregate a datetime measure's field type cannot carry, and reconcile the storage-form annotations to one measured statement #16778 (temporal) and PR feat(service-analytics)!: refuse a deriving aggregate over a field type that cannot carry it, for every field type and not only the temporal class #17559 (sum/avg), the pairs nothing enforces anywhere are exactly 74;
⭐ the 42 string rows cannot be ruled apart from the other 32 — which is a measured argument against the very split AGGREGATE_FIELD_TYPE_COMPATIBILITY refuses min/max over the string classes while 15 shipped end-to-end cases depend on them working — the table or the uses must give #17513 assumed.

⇒ #17513's scope is a subset of this card's, and its framing (string rows as a separable question) is contradicted by this card's measurement. ⛔ Keeping both would leave a card whose premise this one disproves. #17513 closed as duplicate of this card, with its useful content — the 15 shipped cases in measure-result-type.test.ts that would go red — carried here.

Scope

Establish and propose, ⛔ not enforce. Whichever way it goes moves a published contract: enforcing breaks shipped cases, relaxing widens the accepted set. ⇒ Bring the population and the breakage; ⛔ do not edit the table in the same pass.

priority:p2 (up from #17513's p3): the measured population is 74 pairs rather than one class, and the card shows the question cannot be answered piecemeal — so the cost of leaving it compounds across every future aggregate card.

Claim: domain:spec execution seat, session session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-12T15:28Z. Assignee set in the same write; the os-dev round inherits both and ⛔ posts no second claim.

Branch: claude/issue-17560-aggregate-field-type-enforcement

Clause-②: no — the table already refuses these 74 pairs; this round makes the refusal reach a door. Nothing starts being accepted, no key is added to a published payload. ⚠️ If the round's measurement shows the honest repair is instead to narrow the table (i.e. stop refusing pairs nothing was ever going to enforce), that moves a published accept set and this seat re-declares here — ⛔ the dev does not, and ⛔ it does not quietly pick the cheaper arm.

Why this one is ready

The pattern is established by two landed predecessors, ⛔ not invented here: #16778 did the temporal rows and PR #17559 (card #16099) did every sum / avg row. This card is the measured remainder — min / max over the string-ish and reference classes — filed by the seat that delivered #17559, with the count derived rather than estimated: AGGREGATE_FIELD_TYPE_COMPATIBILITY refuses 155 of 294 pairs, and 74 of those are enforced by nothing anywhere.

⚠️ Read the card and its comment to the last page first; its own filer already corrected one count on it, which is the kind of thing that is cheap to inherit wrongly.

File face: the aggregate compatibility table and the door(s) that must consult it, plus pins and a changeset. ⛔ Declared NOT touched: the temporal rows and the sum/avg rows — those are landed and are ⛔ not re-litigated here.

→ 决策箱。轮次零实现停手是对的,而且它纠正了我;我复核时又发现第三件更要紧的事。

domain:spec 执行席,session_01MkQhmuuJAVDjmeWNixwDDH,2026-09-12T15:45Z。轮次报告 5646900386,PR 无(diff 为空),分支 claude/issue-17560-aggregate-field-type-enforcement 已推但空。

⛔ 先认我自己的错:我的认领把这张卡的范围写反了

分诊在 5626877339 里把范围写死:

Establish and propose, NOT enforce. Bring the population and the breakage; do not edit the table in the same pass.

而我的认领(5646802366)写的是「this round makes the refusal reach a door」—— 那正是 arm (a) 的执行。⇒ 我的派发令与分诊的范围直接冲突,而我没读到最后一页就写了它。 轮次没有选边,而是把冲突标出来交回,这是对的。

轮次纠正的两件事,都实测过

arm (a) 不是「什么都没开始被接受」那么无害。 它字面上 Clause-②: no,但实测破 20 个已发布行为用例,今天能编译的 dataset 会变成 DATASET_INVALID/400。⇒ 它仍然需要 changeset 与 ADR-0087 处置。我的派发令把这一半省略了。
卡面「决定项 2」是假的。 它说 measureResultType 对 min × formula 也答 undefined,所以两处声明一致。实测:该函数取第三个参数(A min/max over a formula field cannot be typed: sourceFieldMeta does not carry FieldSchema.returnType, the key whose own JSDoc names dataset measures as its consumer #16236),measureResultType('min','formula','text') 答 'string'。⇒ formula 从「两处一致」那一桶移进了矛盾桶。轮次的第一次探针对所有 37 组都答 undefined,它没有采信自己的探针,而是拿已发布测试反驳、找出调用签名错了再重测。

⭐ 我复核时发现的第三件事:那条「ruled C」的引用,在树里找不到对应的裁决

已发布的测试散文(aggregate-datetime-measure-refusal.test.ts:493)写着:

min × text is the row ruled C — the table is to be AMENDED to accept it, tracked as #17513

我逐个读了它指向的东西:

AGGREGATE_FIELD_TYPE_COMPATIBILITY refuses min/max over the string classes while 15 shipped end-to-end cases depend on them working — the table or the uses must give #17513 已关,理由 duplicate,唯一一条评论是分诊把它并进本卡 —— 没有任何裁决。
我能找到的、针对这张表的唯一已记录裁决是 No layer refuses an incoherent aggregate / field-type pair — a dataset measure avg over a datetime works on SQLite and errors on Postgres #16099 的 5560090715(总监席,决策批 Validation Protocol: Cross-Field, Async, and Conditional validation #59,2026-09-06),其正文逐字写着:

Starting rows, ruled here…: count/countDistinct any type; sum numeric only…; avg numeric…; min/max numeric plus date/datetime; everything else refused.
⇒ 它把 string 类判为拒绝,与散文说的「to be AMENDED to accept」方向相反。
那条裁决里维护者的逐字回复是「16063 c, 其他同意」。而 @objectstack/spec's browser dist carries authoring documentation prose (Zod .describe() strings): 17.3.0 is +292.2 KB gzip on every browser consumer — should the browser build carry it at all? #16063 是另一张卡 —— 「@objectstack/spec 的 browser dist 携带 .describe() 散文,17.3.0 +292.2 KB gzip」,与聚合表毫无关系,且已 not_planned 关闭。⇒ 那个 c 是给那张卡的选项,不是这张表的行。
spec: declare the aggregate × field-type compatibility matrix (AggregationFunction × FieldType) that dataset measures are refused against (spec half of #16099) #16353(声明这张矩阵的 spec 卡)已 completed 关闭,7 条评论中没有任何一条提到修订 string 行。
⚠️ 而 ruling C 在本仓是个通用说法:filter-normalizer.ts:1594 里的是「[engine] driver-sql 编译 spec 未声明的「数组 where 方言」—— 与 Turso remote 的拒收分叉,需一次定调(接纳进 spec 或响亮弃用) #5158's ruling C」,另一件事。

⇒ 已发布的测试散文断言了一条它没有指名、而我在树里找不到的裁决,并且与我能找到的那条方向相反。 ⛔ 我不据此宣布它是误引 —— 我找不到,不等于不存在;但它不可从树里核实,而两条钉子正以它为由阻挡执行。

os-decision-facets

① 项目长远合理性:表说拒绝、measureResultType 说 'string'、门不执行、散文说要改表 —— 四处声明互不一致,这是 declared≠enforced 的最坏形态:它不是漏了一个门,而是没人知道哪句话作数。任一方向落定都比现状好。
② 实际业务拉动:⚠️ 有真实拉动,而且方向朝着接受:20 个已发布行为用例依赖 min/max 在 string 类上能用,今天能编译的 dataset 会因执行而变 400。⇒ 执行不是「补上遗漏」,是破坏已发布行为。
③ 防 AI 犯错:两个方向都能治。今天最糟的是中间态 —— 元数据作者写下一个表说拒绝的组合,系统照样编译并返回结果,而门禁、lint、类型三处各说各话。
④ 创业阶段不扩散:接受(改表)只动一张表加一份 changeset;执行要同时处理 20 个用例、一份 ADR-0087 处置、以及那两条明写「等裁决先动」的钉子。⇒ 就地成本上,接受更小。

维护者速读

我们有一张表,规定「哪种统计能用在哪种字段上」。它写着:最小值/最大值不能用在文本类字段上。

但实际上现在就能用,而且我们自己有 20 个已发布的测试在依赖它能用 —— 也就是说,产品今天的真实行为和这张表写的相反。更麻烦的是,代码里还有第三处声明说「文本字段取最小值会返回一个字符串」,那又和表相反。

两条路:要么改表(承认文本类可以取最小/最大,让表跟上现实),要么执行表(从此拒绝,代价是那 20 个用例和任何现在能跑的报表会开始报错 400)。

⚠️ 还有一件事你可能想知道:代码注释里写着「这一行已经裁定要改表了」,但那条裁决我在 GitHub 上找不到 —— 它指向的卡是空的,而我能找到的唯一一条裁决说的是相反的(拒绝)。所以这件事现在没有可核实的依据,只能问你。

文本类字段的最小值/最大值,改表接受,还是执行拒绝?A(改表接受)还是 B(执行拒绝)。

状态与去向

pm:dispatched → needs-user-decision;assignee 留着(活是本席的,答复一到就接着落)。⛔ 无 PR,分支空;⛔ 表没动,门没改,一个 pin 都没写 —— 轮次明确不写,理由是任何一组 pin 都会把两条路里的一条编码进去,而选路正是这张卡要问的事。

⚠️ 另外两个半边(16 个非 string 组、以及 formula)在轮次报告的 open_questions 里,本席不在此并问 —— 它们的答案依赖上面这一问。

Ruling recorded — B: the compile door enforces the table for every aggregate; all 74 unenforced `min` / `max` pairs are refused in one pass — the "ruled C" prose in the tree has no ruling behind it (director seat, decision batch #127 item 3, 2026-09-13)

Maintainer, verbatim (live PM chat, reply received 2026-09-13T05:5xZ), to decision batch #127 presented as 1B·2A·3B·4B·5C′: 「16678 具体解释，计划用哪个字段判断经理。其他同意」 — 「其他同意」 covers this card.

The ruling on record, quoted

The only recorded ruling on this table is decision batch #59 on #16099 (5560090715, 2026-09-06, maintainer verbatim 「16063 c, 其他同意」):

count/countDistinct any type; sum numeric only, excluding percent; avg numeric including percent; min/max numeric plus date/datetime; everything else refused.

The table's own docblock (packages/spec/src/data/aggregate-field-type-compatibility.ts) records the string classes as refused "as ruled" and names measureResultType's 'string' result as the existing opinion it overrides. The sentence in aggregate-datetime-measure-refusal.test.ts:493 — "min × text is the row ruled C … tracked as #17513" — points at a card closed duplicate with zero rulings on it, and #16099's own "waiting on #16785" points at an issue number that does not resolve. ⇒ There is no ruling C. The 20 shipped cases pin an opinion, not a decision.

Derived first from the long-term axis: the protocol is the source of truth and code that disagrees with it is changed (maintainer standing ruling). The reference platforms this platform's reporting resembles refuse the pair — Salesforce report summaries offer Sum/Avg/Max/Min on number/currency/percent and Max/Min on date/datetime, text is not summarisable; Looker's type: min / max are for numbers and dates (director-seat memory pointers, ⛔ not measured) — and the table's own reason stands: the order of strings is collation-dependent, so two backends answer two "smallest" values for one metadata document. Business pull: HotCRM (shallow clone c716a2c) ships 30 dataset measures — count 14 / sum 10 / avg 6 — and zero min / max; the 20 cases are in-tree fixtures, not customer usage. Zero pull ⇒ no widening. ②③④ do not overturn ①; ④ is costlier under B and does not flip it.

What is ruled — the three sub-questions together

String classes (42 pairs): refused, as batch Validation Protocol: Cross-Field, Async, and Conditional validation #59 rules. ⛔ The table is not amended.
Non-string classes (32 pairs): refused and enforced.
formula: refused, on the table's own storage ground — it is VIRTUAL in SQL storage, no column is emitted, so no aggregate can be lowered to it whatever returnType says; the five formula-return-type-measure cases pin a result TYPE, not a capability, and are retired with the reversal named.

Execution (one pass, ⛔ not per field class)

dataset-compiler.ts: the if (!DERIVING_AGGREGATES.has(aggregate)) return; gate goes; assertAggregateFieldTypeCompatible judges all six aggregates through the same DATASET_INVALID / 400 door.
measureResultType (service-analytics): no longer answers 'string' for a pair the table refuses — the STRING_SOURCE_FIELD_TYPES branch is retired and the formula branch aligned; the function's declared verdicts and the table agree by construction.
Tests: the shared fixture in measure-result-type.test.ts is re-aimed off refused pairs (the service-analytics: AVG() over a Field.datetime measure returns SQLite's text→numeric coercion (an average YEAR) with no error, and derived: { op: 'difference' } renders the difference of two of them as a clean plausible number #16737 precedent in the same file); the two conditional pins (aggregate-nontemporal-measure-refusal.test.ts:261, aggregate-datetime-measure-refusal.test.ts:491) are flipped naming batch Validation Protocol: Cross-Field, Async, and Conditional validation #59 and this ruling, ⛔ never deleted; the negative control that accepted pairs still compile (min × number) is kept; the eight #17513 citations are rewritten to this card.
The table's TSDoc "override" paragraph is rewritten as settled ground: the overridden opinion is retired, ⛔ not still standing beside it.
Breaking: a dataset that compiles min / max over a refused type today answers DATASET_INVALID / 400. Changeset under the launch-window convention (minor, with the BREAKING banner); ADR-0087 semantic migration entry — no lossless conversion exists, so the entry writes the structured TODO naming the measure and the field type.
Clause-②: no — this pulls the code back to the declared contract; nothing starts being accepted. The lint leg is unchanged (lint: refuse an incoherent dataset measure (aggregate × field type) at authoring time, from the spec's compatibility matrix (lint leg of #16099) #16354 stays its carrier).

Difference from the seat's and the round's recommendation, stated: both recommended A on the ground that "ruling C is already recorded in the tree"; that record is unverifiable and is contradicted by batch #59 and by the spec file itself. Confidence gap: customer datasets in cloud were not readable; HotCRM reads zero.

State

needs-user-decision → pm:dispatched (the domain:spec seat's claim 5646802366 stands, assignee kept, branch claude/issue-17560-aggregate-field-type-enforcement); the claim's scope now matches triage's: establishing is done, enforcing is ruled. domain:spec / priority:p2 kept.
