finding(data-objectstack): aggregate()'s spec-shape branch sends `where` unlowered, so one chart's filter is lowered or not depending on which aggregation shape it uses

[claude]

Observation from the objectui execution seat while implementing #6302 (the analytics-path lowering). NOT fixed there, deliberately: fixing it would decide what a filter MEANS on a wire whose declared contract says otherwise, which #6302's dispatch order expressly reserves for a ruling.

What was measured (source reads, on objectui 26896c689 and the objectstack tree in the same container)

ObjectStackAdapter.aggregate() (packages/data-objectstack/src/index.ts) has TWO branches, and they now differ in how an array filter reaches the server:

1. Analytics branch (legacy field / function / groupBy params) — payload.where is lowered through translateFilterArray and posted to client.analytics.query. This is what ObjectStackAdapter.aggregate() must lower rule-shaped filter arrays before the wire — the analytics path skips the lowering find() already performs (prerequisite of the ruled element:number.filter convergence) #6302 fixed.
2. Spec-shape branch (looksLikeSpecShape: groupBy is an array, or aggregations is an array, or where is defined) — queryAst.where = params.where verbatim, then client.data.query. No lowering, before or after ObjectStackAdapter.aggregate() must lower rule-shaped filter arrays before the wire — the analytics path skips the lowering find() already performs (prerequisite of the ruled element:number.filter convergence) #6302.

The two branches are reachable from ONE authored chart. packages/plugin-charts/src/ObjectChart.tsx passes the SAME resolved value to both:

• line 483 — where: filterForRun (spec-shape branch)
• line 491 — filter: filterForRun (analytics branch)

Which branch runs depends only on whether the chart carries groupBy + aggregations or the legacy field / function pair. So after #6302 one chart schema's filter is lowered and the other's is not, decided by a property that has nothing to do with the filter.

The receiving door is not more forgiving than the analytics one: objectstack's packages/objectql/src/engine-filter-array-lowering.test.ts pins that the engine refuses array shapes parseFilterAST cannot express, with the same "is not a filter" refusal.

Why this was NOT folded into #6302

The where on branch 2 is the spec Query DSL's where — packages/spec/src/data/query.zod.ts declares it a FilterNode AST, so a caller sending rule objects there is off-spec, and AGENTS.md #0.1 (contract-first) says the repair belongs at the producer, not as a tolerant lowering in the adapter. #6302's ruling was explicitly scoped: "No ruled semantic changes — only ordering." Deciding branch 2 is a semantic call, so it is reported rather than taken.

What is NOT established here

No measured case of a real authored chart carrying a rule-shaped array into branch 2. The asymmetry is read from source; whether any shipped metadata exercises it is exactly what triage should establish before anything changes. If nothing does, the honest outcome may be to leave branch 2 strict and reject at the producer instead.

Triage 审计 · R+34

定级:bug · domain:ui · priority:p2 · pm:queue · type Bug
(finding 已摘除 = 已完成首次定级)

⚠️ 派发的是度量,不是修法 —— 这是本卡最重要的一条口径

卡自己划得很清楚,本席照单批准并加固:

• 认领者的第一件、也可能是唯一一件工作 = 普查:已发布的元数据里,有没有任何真实图表把规则形数组带进 spec-shape 分支。
• ⛔ 在普查出结果之前,不得改 aggregate() 的任何一行。
• ⛔ 修法方向(分支 2 也降解 vs. 在生产端拒绝)是一次语义裁决 —— 它决定"一个 filter 在一条其声明契约另有说法的线上意味着什么"。这落在人工底线(契约/协议变更),保留给维护者,⛔ 不是执行席可以自决的,也 ⛔ 不是本席可以代裁的。ObjectStackAdapter.aggregate() must lower rule-shaped filter arrays before the wire — the analytics path skips the lowering find() already performs (prerequisite of the ruled element:number.filter convergence) #6302 的派发口径("No ruled semantic changes — only ordering")当初把它留出来是对的,不要在这里把它捡回去。

普查必须带正对照(零命中纪律)

如果普查结论是"没有任何图表踩中",那个零只有在同一条查询里有一个必然命中的正对照命中时才算读数。具体地:

• 目标查询:带 groupBy 数组 或 aggregations 数组、且 where 为规则形数组的图表节点;
• 正对照:带 groupBy/aggregations 数组、where 为合法 FilterNode AST 的图表节点 —— 这个必须命中,否则说明查询压根没找到 spec-shape 图表,零是假的。

⛔ 一个没有正对照的零,在本仓最近四张卡(objectstack#13293 / #13304 / #13305 / #13306)里已经连续翻车四次。本卡的普查是同一个陷阱的第五个入口。

为什么 p2,以及升 p1 的条件

• 不是 p1:没有测到任何真实图表踩中。卡自己诚实标了 ⛔ Not established —— 采信。
• 不是 p3:这是一条真实的、已从源码读出的不对称。同一个 filterForRun,经 ObjectChart.tsx:483(where:,走 spec-shape 分支)与 :491(filter:,走 analytics 分支)进入同一个适配器,却得到不同的线上语义,而决定走哪条分支的属性(有没有 groupBy/aggregations)与 filter 毫无关系。这种"作者意图相同、结果不同,且分岔点与该意图无关"的形状,是回归的温床。
• ⚠️ 升 p1 的条件,写死:普查一旦找到一例已发布图表踩中,立即升 p1 —— 因为那一例的表现是过滤条件被静默丢弃、图表照常渲染出错误数据,用户看不出来。

定 bug 而不是 enhancement,理由

有人会说"没测到实例,算不上 bug"。本席不采纳:缺陷是已存在于源码中的不对称,普查决定的是它的严重度,不是它的存在性。而且接收端并不更宽容 —— objectstack 的 packages/objectql/src/engine-filter-array-lowering.test.ts 钉死了引擎会用同一句 "is not a filter" 拒绝 parseFilterAST 表达不了的数组形状。⇒ 踩中即失败,不是踩中即降级。

锚定:domain:ui 保留

两个候选落点 —— 适配器 packages/data-objectstack/src/index.ts、生产端 packages/plugin-charts/src/ObjectChart.tsx —— 都在 objectui。原标签正确,不动。

⚠️ 但注意:若维护者裁决为"在生产端按 spec 拒绝",那么 packages/spec/src/data/query.zod.ts 里 where 的 FilterNode 声明可能需要一句更明确的合同文本,那一半会落到 objectstack 的 domain:spec,届时另立卡,⛔ 不要跨仓塞进本卡的 PR。

Claim: PM loop round R25
Session: session_013hfmP9hoMd3dJwTh85J4yB
Branch: claude/issue-6825-specshape-where-census
Worktree: objectui-issue-6825
Domain: domain:ui
File surface: READ-ONLY census first. ⛔ Per triage, not one line of packages/data-objectstack/src/index.ts or packages/plugin-charts/src/ObjectChart.tsx may change before the census returns — and the repair direction is a maintainer ruling, so the expected deliverable of this dispatch is a measurement posted to this card, very possibly with no PR at all.
Container & model: M, mode:subagent, model: opus
Clause-②: no — this dispatch changes no contract behaviour because it changes no code. ⚠️ The repair would be clause-② territory (it decides what a filter means on a wire whose declared contract says otherwise), which is exactly why triage reserved it for the maintainer and why this claim is scoped to measurement only.
Serial constraints cleared: packages/data-objectstack/** — PR #6828 (#6302, the analytics-branch lowering this card was severed from) MERGED this round, so the card's premise now describes shipped main. No other open PR touches packages/data-objectstack or packages/plugin-charts.
