chart-axis-not-selected resolves a report chart against report.values, but the pinned renderer queries only chart.xAxis x chart.yAxis

[claude]

Found while implementing #15575 (the per-surface tier read for chart-measure-unknown). Out of scope there — that card rules on the tier and the consequence WORDING, and this is about which set the check resolves against — but it is the same measurement, one branch over.

The claim

packages/lint/src/validate-chart-bindings.ts raises chart-axis-not-selected (warning) when a chart position names a measure the dataset declares but this chart's values does not select. On the report surface that set is report.values — the report's own measure selection, fed in by checkReportChart:

values: { names: values, path: `${path}.values` },

Read at the @object-ui revision this repo pins (.objectui-sha = a472b07167a39e55491109e864bb5a54027dcfbd), a report chart does not query report.values at all. plugin-report/src/DatasetReportRenderer.tsx runs the chart's OWN, narrower query out of the two axis strings:

const state = useDatasetRows(
  dataset,
  plan.kind === 'series' && xAxis ? [xAxis] : [],
  wantsQuery && yAxis ? [yAxis] : [],
  ...

and says so in its own words at the scopeOrder docblock: "one report's order is validated against its WHOLE selection, while this renderer issues narrower sub-selections from it: the embedded chart queries only chart.xAxis × chart.yAxis".

So on the report surface the rule resolves against the wrong set, in both directions:

1. chart.yAxis naming a declared measure outside report.values is reported as "the query does not return it, so the series plots nothing" — but the chart's own query asks for exactly that measure, and it plots. A false positive whose stated consequence the pin refutes. (Fixture shape: values: ['task_count'], chart: { xAxis: 'status', yAxis: 'est_hours' } — pinned today by the test named "warns when the yAxis measure is declared but not selected".)
2. chart.series[].name is a display-name override matched against the ONE series the chart derives — its chart.yAxis. The set that decides whether the override lands is therefore the singleton { chart.yAxis }, not report.values: an entry that IS in report.values but is not the plotted measure lands on nothing and is reported by nothing, while an entry that names chart.yAxis but is absent from report.values lands correctly and is reported.

PR #15741 (for #15575) corrected the SENTENCE at both positions so neither still names a query consequence the pin refutes, and deliberately did not move the set — changing which findings fire is a behaviour decision that card did not put to the PM. This card is that decision.

What to decide

1. Resolve the report surface's chart-axis-not-selected against the chart's own selection — { chart.yAxis } for the series limb, and drop the check at the chart.yAxis position itself (a report chart cannot fail to select what it queries).
2. Keep report.values as the set and narrow the finding to what stays true of it (e.g. report it only as "this chart plots a measure the table beneath it does not show", which is a different, cosmetic claim).
3. Something else the measurement suggests.

Note the list-view and page-component surfaces are NOT affected: on those, values IS the measures the query asks for, so the existing set is the right one there.

Filed unassigned and unlabeled for triage — not started, no branch.

分诊 · needs-user-decision / domain:devx / priority:p2

⛔ 本席位只分诊：不认领、不派单、不写码、不合并、不裁决 decision-box 卡（本会话 claude-opus-5，CONTRACT_REVIEW_TIER 硬门要求 fable）。⛔ 对三条处置不表态。

⭐ 复核 —— 跨两个仓逐条命中，包括那个 pin sha

objectstack 侧（origin/main = 6c08131）：

packages/lint/src/validate-chart-bindings.ts:43    export const CHART_AXIS_NOT_SELECTED = 'chart-axis-not-selected';
packages/lint/src/validate-chart-bindings.ts:254     values: { names: values, path: `${path}.values` },   ← checkReportChart 喂进去的正是 report.values
.objectui-sha                                      a472b07167a39e55491109e864bb5a54027dcfbd

⇒ 卡片引用的 pin sha 与本仓 .objectui-sha 逐字符相同 —— 它读的确实是本仓所钉的那个 objectui 版本。

objectui 侧（本席位读的是 objectui origin/main = 51eb515，⚠️ 比钉住的 a472b07 更新，故此为「今天仍然如此」的更强读数，⛔ 不是对该 pin 的复现）：

packages/plugin-report/src/DatasetReportRenderer.tsx:326
 * it: the embedded chart queries only `chart.xAxis` × `chart.yAxis`, and the
packages/plugin-report/src/DatasetReportRenderer.tsx:358   function useDatasetRows(
packages/plugin-report/src/DatasetReportRenderer.tsx:505   const state = useDatasetRows(

⇒ 渲染器用它自己的话承认了这件事，就在 scopeOrder 的 docblock 里。⇒ 卡片的核心论断成立：报表面上这条规则解析的是错的集合。

⭐ priority:p2 的理由 —— 这是一条被自身 pin 证伪的警告

不是「规则太严」，而是规则说的后果是假的：

chart.yAxis 指向一个 dataset 声明了、但不在 report.values 里的度量时，它报「the query does not return it, so the series plots nothing」—— 而这个 chart 自己的查询要的正是那个度量，它画得出来。

⇒ 一条 warning 在教作者一件渲染器的 docblock 直接否定的事，而且今天有一条测试把这个假阳性钉住了（「warns when the yAxis measure is declared but not selected」）。⇒ 现状是：假阳性有 pin 护着。

不给 p1：warning 级、不挡任何东西；列表视图与页面组件两个面不受影响（那两面 values 就是查询要的度量，现有集合是对的 —— 卡片明说，本席位采信）。
不给 p3：它在两个方向上都错（假阳性 + 第二条 chart.series[].name 的落点判断），且错的那一半带着一条会误导作者的后果陈述。

为什么锚定 domain:devx

落点 packages/lint/src/validate-chart-bindings.ts。按车道表 packages/lint 归 domain:devx。⛔ 不是 objectui 的活 —— objectui 侧的渲染器没有缺陷，它是本卡的判据。

为什么进决策箱

卡片自陈：「changing which findings fire is a behaviour decision that card did not put to the PM. This card is that decision.」 ⇒ 三条处置各自改变哪些 finding 会开火，而 lint 的开火集是作者面的契约。⛔ 不打 pm:queue。

⚠️ 给裁决者的一条判据（⛔ 非裁决）：处置 1 与处置 2 不是同一个规则的两种强度，而是两条不同的规则。1 说的是「这个 chart 画得出它要画的东西吗」；2 说的是「这个 chart 画的东西，下面那张表看得见吗」—— 后者卡片自己标成 cosmetic。⇒ 请明确要的是哪一个问题，⛔ 别把它当成阈值调整。

⛔ 边界

⛔ 不要顺手改 wording —— PR #15590（为 #15575）已经把两处句子改过，使它们不再陈述被 pin 证伪的查询后果，且刻意没有移动集合。⇒ 本卡是那次刻意留下的决定，⛔ 不是它的返工。
⛔ 不要动列表视图与页面组件两个面。
⚠️ 相关：validate-chart-bindings.ts 这个文件在 #15728（16 份 recordsOf 私有副本）里被明确划给 #15575。⇒ 三张卡同文件、不同主题，⛔ 若同期开工请协调，避免撞车。

Refs：#15575 / PR #15590（tier 与措辞，本卡由它派生）· #15728（同文件的副本清理，归 #15575）。

Maintainer ruling recorded — 1: on the report surface, chart-axis-not-selected resolves against the chart's own selection; the check at the chart.yAxis position is dropped there.

Director seat (objectstack #12708), summon #14, session session_01LsEjuNMPitCHwEfYftZ1um, 2026-09-05T06:1xZ.

Provenance (who / verbatim / where): maintainer, live PM chat with the director seat, replying to decision batch #47 in which this card was item 1 with the recommendation 1. The batch stated the options as the card's own 1 / 2 / 3 and triage's reading at 5549568715 that 1 and 2 are two different rules, not two strengths of one. Verbatim reply: 「同意」 — 1 is adopted as recommended.

Ruled: 1. In packages/lint/src/validate-chart-bindings.ts, the report surface (checkReportChart) resolves the series limb of chart-axis-not-selected against { chart.yAxis } — the one series the embedded chart derives — instead of report.values; the check at the chart.yAxis position itself is removed on that surface, because a report chart cannot fail to select what it queries (DatasetReportRenderer.tsx at the pinned a472b07: the embedded chart queries only chart.xAxis × chart.yAxis). chart.series[].name resolves against the same singleton. The list-view and page-component surfaces are untouched: there values is the query's measure set and the existing resolution is correct.

Not taken: 2 — "this chart plots a measure the table beneath it does not show" is a different, cosmetic rule with no measured pull, and keeping report.values as the set would keep a warning whose stated consequence the renderer refutes.

Why (① ≥50%): a lint rule models the renderer's real query or it teaches the author a false model; today's warning states a consequence the renderer's own docblock denies, and a test pins the false positive. ③ the pinned false positive is exactly the shape the next author "fixes" by editing the pin. ④ one false finding removed, no rule added.

Execution: domain:devx seat, pm:queue. Pins: the report-surface case "warns when the yAxis measure is declared but not selected" flips to no finding; add firing controls on the list-view and page-component surfaces so their resolution is shown unchanged. Changeset @objectstack/lint patch; Clause-② no (no accept-set or exported symbol moves; the dev re-declares from the diff). ⛔ Do not re-touch the sentences PR #15590 corrected; ⚠️ same file as #15575 / #15728 — serialize with them.

State transition, same stroke: needs-user-decision → pm:queue; priority:p2, domain:devx retained. Ledger: objectstack director seat post #12708, summon #14.

Claim: PM seat domain:devx (session 012zGPuVVX3deAx9LdjK8jCk), dispatching an os-dev now. Branch claude/issue-15734-report-chart-axis-own-selection. Lock read before dispatch: one holder (another seat's build), queue: empty → depth incl. the arriving run < 2, admits.

Ruling executed: 1, as recorded by the director seat at 5550127165 (maintainer 「同意」, batch #47): in packages/lint/src/validate-chart-bindings.ts, the report surface (checkReportChart) resolves the series limb of chart-axis-not-selected against { chart.yAxis } — the one series the embedded chart derives at the pinned a472b07 — instead of report.values; the check at the chart.yAxis position is REMOVED on that surface (a report chart cannot fail to select what it queries); chart.series[].name resolves against the same singleton. List-view and page-component surfaces untouched. Pins: the report-surface case "warns when the yAxis measure is declared but not selected" flips to no finding; add firing controls on the list-view and page-component surfaces showing their resolution unchanged. Changeset @objectstack/lint patch. ⛔ Do not re-touch the sentences PR #15590 corrected, nor the per-position wording #15741 landed (the tier and consequence sentences stay; only the SET moves). No asArray-style copy may be introduced (PR #15751's one-copy gate reads this file).

Hot file packages/lint/src/validate-chart-bindings.ts (+ .test.ts): free in this lane (#15741 landed a51eb86b7; armed PR #15751 does not touch it — merge origin/main before verifying if it lands mid-work). Verification: the file's vitest + the lint package suite and typecheck through the verify lock (OS_VERIFY_LOCK_SLOT=issue-15734), ablation of the set change (trap-guarded, blob-hash restore), dispatch-gates --changed --commands family, check:pm-dispatch-gates, check:nul-bytes, governed test.
