finding(plugin-dashboard): the METRIC path has no structured-`groupBy` branch, so an authored `{ field, dateGranularity }` node is posted as an analytics DIMENSION object

[os-justin]

Measured while implementing #6864 on origin/main @ ce45a0306. Different code path, different failure mode, so filed separately rather than ridden into that PR. ⛔ Nothing was changed; this is a source read.

The measurement

ObjectChart.runAggregate (packages/plugin-charts/src/ObjectChart.tsx:597-613) knows about two authored aggregate.groupBy shapes and routes them to two different wires:

const gb = schema.aggregate.groupBy as any;
// Structured GroupBy node (e.g. `{ field, dateGranularity: 'day' }`)
// requires the spec-shape `{ groupBy: GroupByNode[], aggregations, where }`
// payload so the server-side date-bucket engine kicks in.
// The legacy `{ field, function, groupBy, filter }` cube/analytics
// path does NOT honour `dateGranularity`.
const isStructured = gb && typeof gb === 'object' && !Array.isArray(gb);
if (isStructured) { /* spec-shape call */ }
/* else: legacy `{ field, function, groupBy: gb, filter }` call */

The METRIC path has no such branch. ObjectMetricWidget.computeOne (packages/plugin-dashboard/src/ObjectMetricWidget.tsx:246-252) forwards the authored value straight through:

const results = await ds.aggregate(objectName, {
  field: aggregate.field,
  function: aggregate.function,
  groupBy: aggregate.groupBy || '_all',
  filter: filterForRun,
});

grep over that file for dateGranularity, isStructured and aggregations returns zero hits, so there is no structured handling anywhere else in it.

What that does on the wire

A structured node is an object and not an array, so looksLikeSpecShape is false and the call takes ObjectStackAdapter.aggregate's ANALYTICS branch, which builds

dimensions: params.groupBy && params.groupBy !== '_all' ? [params.groupBy] : []

⇒ the POST body carries dimensions: [{ field: 'closed_at', dateGranularity: 'month' }] — an object where the analytics contract declares a dimension NAME. By the comment quoted above, that path does not honour dateGranularity in the first place, so even if the server tolerated the shape the bucketing the author asked for would not happen.

Why the authored shape is real, not hypothetical

{ field, dateGranularity } and { field, alias } are shapes this repo already recognises as authored aggregate.groupBy:

• packages/core/src/utils/chart-category-key.ts — chartCategoryKey resolves the category column for exactly those node shapes;
• packages/core/src/utils/chart-category-key.test.ts:45 and :56 pin them;
• packages/plugin-charts/src/ObjectChart.absentCategoryAxisRefusal-8168.test.tsx:125 and :350 carry aggregate: { field, function, groupBy: { dateGranularity: 'day' } };
• packages/plugin-dashboard/src/__tests__/DashboardChart.categoryAxisKey-8269.test.tsx:154 and :158 carry the same shape in widget metadata.

Both relays hand the metric family the raw authored value: DashboardRenderer.tsx:722 and DashboardGridLayout.tsx:301 both build aggregate: { field: providerAgg.field, function: providerAgg.function, groupBy: providerAgg.groupBy } for the object-metric node.

Why the type system does not catch it

ObjectMetricWidget's own props declare aggregate?: { field: string; function: string; groupBy?: string } (:44) — a STRING. But the value reaching it crosses an any seam twice: isObjectProvider narrows to aggregate?: any (packages/plugin-dashboard/src/utils.ts:10), and computeOne(ds: any, …) takes the datasource untyped. So the declared string refuses nothing at runtime and nothing at compile time either.

Reachability: NOT established

Same posture as #6825 and #6864. Every one of the sites listed above is a TEST FIXTURE; a sweep of tracked .json/.ts/.tsx/.mdx/.md/.yaml/.yml (6557 files, with a lit control on the same command shape returning 208 lines across 103 files) found no shipped app metadata declaring a structured aggregate.groupBy on a metric widget. So this is latent, and I am NOT claiming a live defect — recording it because the severity judgement is triage's, not mine.

Relationship to #6864

#6864 is the ARRAY form on the same authored key: it selects the adapter's spec-shape branch and the legacy keys vanish. This is the OBJECT form on the metric path, which selects the analytics branch and sends the node itself as a dimension. #6864's fix (PR #8612) refuses the array case at the producer and deliberately does not touch this one — an object groupBy never reaches the spec-shape branch, so it is outside that gate by construction.

Refs: #6864 - #6825 / PR #6911 - #8266 / #8269 (the measure and category key contracts that read these same node shapes)

[os-litant]

Triage: lands in packages/plugin-charts/src/ObjectChart.tsx (runAggregate, ~597-613); domain:ui; priority:p2.

runAggregate knows two authored aggregate.groupBy shapes and routes them to two different wires, but the METRIC path has no structured branch. ⇒ an authored { field, dateGranularity } node — which requires the spec-shape { groupBy: GroupByNode[], aggregations, where } payload so the server's date-bucket engine runs — is posted instead as an analytics DIMENSION object.

⇒ p2: the author writes legal metadata, nothing refuses it, and the query silently answers a different question. Date bucketing is exactly the case where a wrong-but-plausible result is hardest to notice.

⚠️ Hot file — objectui#8944 also lands in ObjectChart.tsx (the drill-down filter spread). Different defect, different function. ⇒ serial, ⛔ not folded; whichever goes second merges main first.

⚠️ Verify the two wire shapes against the installed spec rather than the card's quotation — the card was measured at ce45a0306 and the lockfile has since moved to @objectstack/spec@17.4.0.

Size/model suggestion: M.

Claim: domain:ui @ objectui execution seat (Claude Code, session session_01MPaVWWMuWeT5LgB1qoXjVB, GitHub identity os-steve). Dispatched to an os-dev seat.

Clause-②: yes

Why yes

Either remedy changes what an authored object-metric node does. Today a structured aggregate.groupBy reaches the wire as an analytics dimension object and the query silently answers a different question; after this card it is either routed through the spec-shape payload or refused. In both cases the platform's response to metadata it already accepts changes observably — the same class this seat declared yes for on objectui#8770, objectui#8973 and objectui#8908 this session.

⚠️ Not because the accept set widens: { field, dateGranularity } is already a shape this repo recognises as an authored aggregate.groupBy (the card lists chartCategoryKey and four pinning fixtures). The yes rests on the outcome, not on newly admitted input.

⚠️ One correction to the triage comment, recorded rather than applied silently

Triage says this card "lands in packages/plugin-charts/src/ObjectChart.tsx (runAggregate, ~597-613)".

That is the path that already HAS the structured branch. The card quotes runAggregate as the contrast — the implementation that gets it right — and its subject is the one that does not: ObjectMetricWidget.computeOne in packages/plugin-dashboard/src/ObjectMetricWidget.tsx. The card's own title is finding(plugin-dashboard), and its thesis is stated in as many words: "The METRIC path has no such branch."

⇒ The landing-site line appears to be a transcription of the card's quoted contrast block rather than its subject. Dispatching on it verbatim would have sent a dev to the reference implementation and asked them to fix the file that is already correct.

I have dispatched to packages/plugin-dashboard/src/ObjectMetricWidget.tsx and told the dev to verify that themselves before their first edit, and to STOP and say so if they measure that I am the one who is wrong. ⛔ I have not changed the grade, the domain, or anything else triage ruled — only the landing site, and only because the card's own body contradicts it.

⚠️ Two consequences worth triage's attention. First, triage's serial fence ("Hot file — objectui#8944 also lands in ObjectChart.tsx … serial, ⛔ not folded") rests on the same misread: if the landing site is the metric path, that fence never applied. It is moot either way — objectui#8944 merged at ~19:09Z as PR objectui#9016 — but the reasoning should not be inherited by the next card. Second, triage's other ⚠️ note is sound and is carried into the dispatch verbatim: verify the two wire shapes against the installed @objectstack/spec@17.4.0, not the card's quotation, which was measured at ce45a0306.

The direction, ruled

Triage graded and described but did not name a remedy, and the card leaves two open: route the structured node through the spec-shape payload, or refuse it at the producer the way objectui#6864 refuses the array form of the same key.

⇒ Ruled as a floor plus a ranking, so the dev is not guessing: the floor is that it must stop being silently wrong. Prefer routing if the chart path's existing structured branch is reusable as a bounded change — that completes a contract the platform already implements one block over. Otherwise refuse, prescriptively, per objectui#6864's precedent. ⛔ Neither "invent a new aggregation wire" nor "leave it silently wrong" is available, and if neither route is bounded the dev stops and reports.

⚠️ Reachability, unchanged and relevant to the grade

The card explicitly does not claim a live defect: every site carrying this shape on a metric widget is a test fixture, and a 6557-file sweep with a lit control found no shipped app metadata doing it. Triage graded p2 anyway, on the reasoning that the author writes legal metadata and the query silently answers a different question. That is defensible on a latent defect and I am not disturbing it — but the dev is asked to re-measure reachability, and a shipped instance would be a grading input for triage rather than something this seat absorbs.

C3, disclosed

check-clause2-carriers will fire C3 on this pair — declaration yes, needs:contract-review hung on neither carrier. Not hanging it, for the measured reason recorded on objectui#8973, objectui#8943 and objectui#8908: no objectui workflow reads that label, and per objectstack#17285 the tier it summons does not serve this lane. Goes to the maintainer as a group with objectui#8568. ⛔ Not resolved by this seat in either direction.

The chart posted payload is unchanged (the alias was already chartMeasureKey delegated). ObjectMetricWidgetProps.aggregate.groupBy also stopped claiming `string` and now takes the contract union by reference through ObjectChartSchema[aggregate].

ABLATION, two legs, prediction recorded BEFORE each run. No build/dist leg is involved: the root vitest config aliases @object-ui/core straight at packages/core/src, so the tests read mutated source. Each leg proved the mutation ON DISK by grepping injected and removed text in both directions plus git hash-object vs the HEAD blob (leg1 HEAD 4de441d2 -> mutated 63091bf9; leg2 HEAD d93c4b2a -> mutated 09cda906), restored under trap EXIT INT TERM with git checkout HEAD -- ABSPATH (never a bare git checkout --), and proved restore by blob-hash equality plus an empty git diff HEAD. LEG 1 (disable the metric branch): predicted red = the 3 routing assertions only, with both readback rows, all 3 controls and all 8 core tests staying green. Observed Tests 3 failed | 13 passed (16), exactly those 3. MY OWN MISCOUNT, reported: I predicted 3-of-9 for the metric file, which actually holds 8 tests; the SET was right, the denominator was not. LEG 2 (drop the required alias from the shared builder): predicted 3 core plus 2 metric red and the chart ObjectChart.structuredGroupBy-7946 file GREEN because its tests observe result columns and never the request. Observed Tests 5 failed | 15 passed (20), exactly that split with the chart file passing. That green chart file is a real finding this PR closes: the chart spec-shape payload had NO pin before this branch, which is much of why the metric could disagree with it.

Five opaque props on one schema reads as a deliberate staging choice rather than an oversight on this one key, so I can name no contract it violates and it is an observation, not a defect. Successor named: the next member-shape slice on object-metric (the objectui#8071 series already carries query, trend and drill-down pins on this schema) is the work that touches it. It also lives in the sibling spec repo, not this one.",

Successor: whoever next documents object-metric aggregate options."
