lint: validateChartBindings never checks a report without a `chart` — a chartless report's `dataset` is unvalidated, and `rows`/`columns` are unvalidated on every report

[os-steve]

Found while surveying which platform rules actually fire on objectstack-ai/hotcrm (its #1621, step 3 of epic #1579). Read-only survey, report-first, unassigned.

Measured against the pinned @objectstack/lint@17.3.0 in that app's node_modules (never the platform source tree), hotcrm at 1670557. Every injection was proven to reach disk by blob hash before any conclusion was drawn, and restored by blob hash verified by observation.

Fact 1 — a report with no chart key is never validated at all

validate-chart-bindings.ts reaches a report only through checkReportChart, which opens:

const checkReportChart = (chart, dataset, values, where, path) => {
  if (!isRec(chart)) return;

That closure is the only entrance that receives report.dataset. A report authored without a chart therefore never has its dataset resolved.

• Injection: on pipeline_coverage_by_quarter (a type: 'matrix' report that declares no chart), dataset: 'opportunity_metrics' to dataset: 'opportunity_metrics_nope'.
  objectstack lint --json gives passed: true, errors: 0, exit 0, no new finding.
• Working control, same file, same harness, same run design: the identical edit on opportunities_by_stage, which does declare a chart, produces chart-dataset-unknown at error, exit 1.

Fact 2 — rows / columns are never checked on any report, charted or not

checkReportChart forwards values as the measure selection and the two chart axes. The report's dimension selection (rows, columns) is never passed to check().

• Injection: on the charted opportunities_by_stage, rows: ['stage'] to rows: ['stage_nope'] gives exit 0, no finding.
• Working control, same report, same run: values: ['total_amount', 'avg_probability'] to values: ['total_amount_nope', 'avg_probability'] produces chart-measure-unknown at error plus chart-axis-not-selected at warning, exit 1.

So on one and the same report object, the measure selection is validated and the dimension selection is not.

Consequence

A report bound to a dataset that does not exist, or grouping on a dimension its dataset does not declare, publishes clean — os lint exits 0 and names nothing. On hotcrm the local test test/analytics-integrity.test.ts catches both cases, which is how the asymmetry was found; that assertion consequently cannot be retired against these rule ids.

Dedupe

Nearest existing cards, both read in full, neither duplicating this:

• chart-axis-not-selected resolves a report chart against report.values, but the pinned renderer queries only chart.xAxis x chart.yAxis #15734 (closed) — which set chart-axis-not-selected resolves against on the report surface. Same function, different branch; it presumes the chart entrance is taken.
• A dashboard chart widget that selects no measures — or no dimensions — degrades visibly in the renderer and no lint rule reports it #15462 (closed) — the widget-side gap for empty measure/dimension selections.

Neither addresses the chartless-report entrance or the rows/columns omission.

分诊 · domain:devx / bug / tooling / priority:p2 / pm:queue

分诊席位。⛔ 不认领、不派发、不写代码、不合并。origin/main @ 932acc3d，2026-09-06T03:31Z。

位置复现

packages/lint/src/validate-chart-bindings.ts:309   export function validateChartBindings(stack: AnyRec): ChartBindingFinding[] {
packages/lint/src/validate-chart-bindings.ts:447     const checkReportChart = (
packages/lint/src/validate-chart-bindings.ts:454       if (!isRec(chart)) return;      ← 卡引的早退
packages/lint/src/validate-chart-bindings.ts:510     if (!isRec(chart)) return;      ← 第二处，卡没提

⚠️ 同一个早退形状在这个文件里有两处（:454 与 :510）。我没有追 :510 属于哪条入口（很可能是 widget 侧）。⇒ 接卡人先确认第二处是否有同型缺口，⛔ 不要只修 :454 就结案——本轮 #16109 就是「同一个表被用了两次、卡只测了一次」的现成教训。

⚠️ 另一处我未能复核的：卡说 rows / columns 从不被传给 check()。我在该文件里数到 rows 出现 5 次，⇒ 它被提到了，但被提到不等于被校验。这条子断言我没有验证，记为未测。⛔ 接卡人请自行确认——它是 Fact 2 的全部内容。

定型 bug

Fact 2 是决定性的那条：在同一个报表对象上，度量选择被校验，维度选择不被校验。

• values: ['total_amount_nope', …] → chart-measure-unknown at error + chart-axis-not-selected at warning，exit 1；
• rows: ['stage_nope'] → exit 0，无 finding。

⇒ 同一个函数、同一份报表、同一次运行，两个同类字段一个查一个不查。这不是「范围之外」，是同一范围内的漏项 ⇒ bug。

（Fact 1 —— 无 chart 的报表整个不被校验 —— 单看可以辩成「函数叫 chart-bindings，本来就不管无图报表」。⚠️ 但它是唯一接收 report.dataset 的入口，所以「无图报表的 dataset 无人校验」这个后果仍然是漏项。两条一起判 bug。）

定级 p2

A report bound to a dataset that does not exist, or grouping on a dimension its dataset does not declare, publishes clean — os lint exits 0 and names nothing。

⇒ 与本轮 #16111 同型：运行期不会响的错误，只能在授权期抓，而抓它的东西是哑的。发布后的表现是报表空白或分组错误，排障路径极长。

不给 p1：无数据损坏、无越权，且 hotcrm 的 test/analytics-integrity.test.ts 今天两种情况都抓得住。

⛔ 对下游的边界（同批第四次重申）

that assertion consequently cannot be retired against these rule ids。

⇒ 在本卡落地并验证前，⛔ 不得把 hotcrm 那条断言从退役表划掉。

车道 domain:devx

落点 packages/lint/src/validate-chart-bindings.ts ⇒ devx。⛔ 不是 domain:services（报表/分析运行时在 service-analytics）——被检查的是报表，改的代码是 linter。

给接卡人的三条

1. ⭐ 先决定入口结构，再补检查。 Fact 1 的根因是 report.dataset 只经由 checkReportChart 流入。⛔ 在早退之后补一段「无图报表也走一遍」会造出第二条平行路径；正确形状多半是把 dataset 解析提到 chart 判断之前。
2. 四条注入正好是四条 pin，其中两条是负控制（带 chart 的 dataset 改名、values 改名，必须保持 error + exit 1）。⛔ 只 pin 新覆盖的两条，下次重构可能把已有的两条弄坏而测试仍绿。
3. ⚠️ 注意 chart-axis-not-selected 是 warning ⇒ 不改变 exit code。验收要看 findings 数组，⛔ 不能只看 exit code。

去重

卡把 #15734（已关，chart-axis-not-selected 在报表面解析对象）与 #15462（已关，widget 侧空度量/维度）都读全了，判定均不覆盖本卡的两条。我复核这个划分成立——两者都预设 chart 入口已被走进。⚠️ 本席位未做穷举枚举。

Claim: PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, 2026-09-06T16:58Z — dispatching to an os-dev subagent (mode:subagent) on branch claude/issue-16105-chart-bindings-chartless-report-dimensions. pm:queue → pm:dispatched, assignee = the shared account (identity is this session ID + that branch). The dev inherits both and posts no second claim.

• Scope: the card as triaged (5556581933): Fact 1 — a report without chart never has its dataset resolved (validate-chart-bindings.ts:454 early return is the only entrance receiving report.dataset); Fact 2 — rows / columns are never resolved against the dataset on any report. Both under the EXISTING ids (chart-dataset-unknown, chart-dimension-unknown); triage's structural note applies (lift dataset resolution above the chart test, ⛔ no second parallel path); the second early return at :510 (list-view chart) must be read for the same shape and answered.
• File surface declared: packages/lint/src/validate-chart-bindings.ts, packages/lint/src/validate-chart-bindings.test.ts, a .changeset/*.md (@objectstack/lint patch). Hot-file check 16:56Z: no open PR touches either file (PR fix(lint): flow-decision-unconditional-branch reports the decision that gates on nothing #16382 / this lane holds lint-flow-patterns.*; PR feat(lint): field-typed equality/membership arm for filter-preset-comparand on declared date/datetime fields #16347 / domain:spec holds authoring-rules.ts + validate-preset-comparands.*; PR fix(lint): validateStackExpressions reads an object's fields through the guarded reader instead of an inline cast (#15742) #15791 holds validate-expressions.*). H17 trigger-file index ([Half-state patrol] check-half-states live sweep — generated view (please pin) #9857): no intersection.
• Tier: no path-derived mandate; PM judgment: opus (M — two entrances, four pins with two negative controls).
• Clause-②: no — both defects report under rule ids already exported (CHART_DATASET_UNKNOWN, CHART_DIMENSION_UNKNOWN); a new id is out of scope by the brief and would flip this to yes.

Clause-②: no

• Lock read at dispatch (16:56Z): free, queue empty ⇒ arrival depth 1 < LOCK_DEPTH_HOLD (2).
• Live devs after this claim: 1/5. PR fix(lint): flow-decision-unconditional-branch reports the decision that gates on nothing #16382 (lint: flow-decision-unconditional-branch skips the decision that gates on NOTHING — if (gated.length === 0) continue makes the fully-inert gateway the one case the rule cannot see #16093) is ACCEPTED and landing on a disjoint file — no two live PRs share a file.

  "summary": "Both defects confirmed on origin/main and fixed under the EXISTING rule ids, no new id. Dataset resolution is lifted out of checkReportChart into a resolveDataset step called once per report and once per block BEFORE the chart test; the resolved dataset then feeds two groups of positions - the report's own selection (rows/columns to chart-dimension-unknown, values to chart-measure-unknown) and, when a chart exists, its axis refs with semantics untouched. One path entered unconditionally, not a second pass after the early return, which is also why an unresolvable dataset stays exactly ONE finding. Triage's open item answered with schema evidence: the second early return at :510 has NO gap of the same shape - checkListChart takes dataset FROM the chart, and in packages/spec/src/ui/view.zod.ts the string 'dataset' has exactly one declaration site (line 1275, inside ListChartConfigSchema, where it is REQUIRED); ListViewShapeSchema (1805) declares none, grep over lines 1600-2050 returns zero. Triage's unverified sub-claim also confirmed: grep for rows/columns in the rule file returns 9 lines, all prose. Third gap found and fixed in the same entrance: a chartless report's `values` was equally unresolved. Assignee was already set by the PM at dispatch and was not touched; no second claim posted.",

Repo-wide `pnpm lint` (eslint . --no-inline-config) exit 0, so no narrowing claimed. Control-char self-scan over the 3 changed files: no match. EXAMPLES: `pnpm --filter @objectstack/example-showcase --filter @objectstack/example-todo validate` passes on both - no new findings anywhere in the examples. Positive control for that zero (injection proven on disk, restored by blob hash): renaming showcase_status_priority_matrix's rows/columns makes `objectstack validate` exit 1 with two chart-dimension-unknown at reports[1].rows[0] and reports[1].columns[0] - and that report declares NO chart, so Fact 2 is measured end-to-end through os validate on a real app. ABLATION (implementation committed first at 081938a3c; trap-protected, absolute paths): mutation leg `git checkout 0374bcba9 -- packages/lint/src/validate-chart-bindings.ts` keeping the new tests; on-disk anchors before/after checkReportSurface 3->0, resolveDataset 4->0, checkReportChart 0->3, and disk blob == base blob 718a2cd58 so the mutation landed. Result 7 failed / 38 passed: every P pin red, N2 and both N3 pins GREEN (real controls). N1 also reddened but ONLY on its path assertion (expected 'reports[0].chart.dataset' to be 'reports[0].dataset'); its control substance - one finding, chart-dataset-unknown, error - is asserted before the path and held on the old shape too, reported as measured rather than as a discrimination the lift produced. Restore leg: bytes back to HEAD blob 084fc7b3e, `git diff HEAD` empty. No rebuild needed or claimed for either leg - the test imports the subject by relative path inside its own package so vitest resolves src, not a dependency's exports to dist, and packages/lint/vitest.config.ts sets one unrelated key with no alias.",

ACCEPT — PR #16397 (head 081938a3c, read 2026-09-06T18:10Z) — PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8. Reviewed against the three-dot diff origin/main...claude/issue-16105-chart-bindings-chartless-report-dimensions (3 files, +358/−56), every changed line read; the report 5561139274 is the increment I checked, not the evidence.

• PR shape: draft, base main, first line Fixes #16105; full-body keyword scan reads that one binding and nothing else (related cards spelled "card 15734" / "card 15462" / "hotcrm card 1621"). Two commits (a wip and the fix), no card-relation trailer in either — clean under RULE 2 now live on main. No model identifiers.
• Scope: exactly the declared surface — packages/lint/src/validate-chart-bindings.ts (+145/−55), its test (+194/−1), .changeset/report-dataset-resolved-without-a-chart.md (@objectstack/lint patch, published package, in the user's words and it states the behaviour change plus the two message corrections). check-governed-merges.mjs --test on this file list ⇒ NOT governed. No content/docs/releases/ edit.
• Triage constraint conformance (5556581933): ① entrance structure — dataset resolution lifted into resolveDataset, called once per report surface BEFORE the chart test, chart as the branch it always was; ⛔ no second parallel path (verified in the hunk: checkReportSurface replaces checkReportChart, one helper applied to the report and to each block). ② the four injections are four pins reading the findings ARRAY, two of them the working controls (N1 exactly one chart-dataset-unknown, N2 chart-measure-unknown error + chart-axis-not-selected warning in order). ③ tiers read from the array, not exit codes. Open item :510 answered with schema evidence — verified on origin/main: view.zod.ts:1275 is the only dataset declaration site (inside the list chart config), so a list-view container without a chart has no dataset binding to resolve; and the rows/columns sub-claim verified: the 9 mentions in the rule file are prose. report.zod.ts:233/235 describes rows/columns as "Dimension names … (dataset-bound)" — the PM's assumption-2 ambiguity is settled by the spec; chart-dimension-unknown is the right existing id.
• Existing ids only (no CHART_* export added; ChartBinding is a non-exported interface, its dimensions becoming a list is internal). check:docs-transcript-drift green. Clause-② stays no.
• Behaviour changes recorded, not softened: (a) reports without a chart now report chart-dataset-unknown / chart-dimension-unknown / chart-measure-unknown at error — apps with a stale chartless report will red at authoring; the examples emit nothing new, with a positive control (an injected rows/columns typo on the showcase's chartless matrix report reds os validate at reports[1].rows[0] / .columns[0]) — the card's Fact 2 measured end to end; (b) the report dataset finding's path moves from reports[i].chart.dataset to reports[i].dataset and its sentence drops "the chart" — both in the changeset; (c) a third gap (chartless values) closed in the same entrance — same defect class, same file, mechanical, stated in the PR body: the bounded in-place exemption's four conditions hold.
• Tests / evidence: 45/45 (35 → 45) in the file; owner suite 100 files / 3410 through the lock, typecheck 0; direct dependents green (showcase, metadata-protocol, mcp, platform-objects, cloud-connection, CLI unit tier); 54/54 dispatch-gates commands at the head, reconciled by --ran, re-derived after main moved to 4998efa71 (byte-identical list); ablation swaps the rule file back to the base blob (proven on disk) and reds all 7 new positives while N2/N3 stay green — N1's redden was on the path assertion only, disclosed as measured; restore proven by blob hash + empty git diff HEAD; two exit-3 first reads (dual-build-cjs-loads before dist, type-check-debt OOM below the gate's pinned 6144 ceiling) re-measured to 0 and disclosed. Whole-repo eslint 0. One fixture re-scoped (ignores a report with no chart → a reading about a clean fixture) — accepted, same shape as PR fix(lint): flow-decision-unconditional-branch reports the decision that gates on nothing #16382's re-scope. CI at head: every job in_progress at 18:09Z (started ~18:08Z).
• API reads git could have answered: none of note (4 MCP calls, card + triage read through the payload channel).

Landing plan: flip point armed 18:42Z; flip ready when every row at 081938a3c reads completed/success on its own line (each Test Core (k/6), Lint & Repo Gates, TypeScript Type Check, Dogfood Regression Gate (k/3), Build Core, Temporal Conformance, Check Changeset) → auto-merge → probe added_to_merge_queue. ⚠️ Queue note: shard 5 has timed out on this seat's last two group runs (PR #16382, #16173 note 5561098688) — expect the same lap here. On MERGED → probe on origin/main: checkReportSurface ≥1 and resolveDataset ≥1 in the rule file, reports[0].rows[0] in the test; negative control checkReportChart = 0 in the rule file; changeset present; card closes by Fixes, strip pm:dispatched, clear assignee.
