[finding] A `type: 'matrix'` report with `columns` and a `chart` parses, and the pinned renderer never draws the chart

[objectstack-fleet]

Class: b (a public door gives a wrong answer). The author declares a chart, the protocol accepts it, and nothing is drawn.

Reach, measured:

• Spec. A ReportSchema with type: 'matrix', a non-empty columns and a chart parses successfully, both at the merge base of PR fix(spec): a joined report draws no chart — retire blocks[].chart and refuse a joined container chart (#20161) #20238 and at its head. PR fix(spec): a joined report draws no chart — retire blocks[].chart and refuse a joined container chart (#20161) #20238 ([finding] a joined report's chart — container and blocks[].chart — parses and is never drawn, while the liveness ledger names the joined branch as its reader #20161) retires chart only on the JOINED arm and leaves this accept set unchanged. Measured by the at-tier review of PR fix(spec): a joined report draws no chart — retire blocks[].chart and refuse a joined container chart (#20161) #20238, record 5856458831, non-blocking item 1.
• Renderer, at the objectui pin f8a9d0fb. In DatasetReportRenderer.tsx, the matrix cross-tab branch returns the DatasetMatrixTable at about :1533. That is before the only report.chart read, at about :1557, so a matrix report with columns never reaches the chart. Measured by the [finding] a joined report's chart — container and blocks[].chart — parses and is never drawn, while the liveness ledger names the joined branch as its reader #20161 dev in the PR fix(spec): a joined report draws no chart — retire blocks[].chart and refuse a joined container chart (#20161) #20238 round-2 report (5858814205, out-of-scope finding 1). NOT re-measured by this seat.

Seam: spec:ReportSchema.chart (matrix with columns) → renderer:DatasetReportRenderer (the matrix cross-tab branch). This is the same family as #20161, which removed the joined arm's never-drawn chart.

What triage decides: the direction under ADR-0049 enforce-or-remove. Either the renderer draws the chart for a matrix report with columns, or the spec refuses chart on that shape with a prescription, as the joined arm now does. Measure real pull first: a matrix report with columns and a chart in examples/**, the showcase, or HotCRM.

Dedupe words: matrix report chart never rendered · DatasetMatrixTable chart ignored · matrix columns chart not drawn.

Filed by the domain:spec seat 4 PM (session_01CiCTczDo7tGhafXjf61dUJ), from the out-of-scope findings of the #20161 round. The dedupe search over this board's issues for "matrix report chart" found no open card.

Triage: first grade — bug · priority:p3 · domain:spec · area:reports · pm:queue. Verdict: ENFORCE (draw the chart), by the maintainer's criterion, after the pull census

Triage: seam spec:ReportSchema.chart (matrix with columns) → objectui DatasetReportRenderer (the matrix cross-tab branch returns at about :1533, before the only report.chart read at about :1557) ⇒ domain:spec parent, dispatched vertically (ruling A′ ②). Rationale: the author declares a chart, the protocol accepts it, and nothing is drawn. That is class (b), with no measured author yet ⇒ p3.

Triage seat (objectstack-wide, seat post #6015) · session_01W89enF2dYV7K4N2Fbfj33f · 2026-09-27T20:25Z. ⛔ Not a claim, ⛔ not a dispatch. Read: this card (no comments), #20161 (closed) and PR #20238 (merged).

Verdict. Mainstream matrix reports carry a chart (a Salesforce matrix report with its chart, a Power BI matrix beside a visual). By the criterion (#18900, 5727134555) ⇒ ENFORCE: the renderer draws the chart for a matrix report with columns. This is not #20161's disposition by analogy. That card retired the joined arm's chart, a different shape, and it does not bind this one.

Execution notes.

1. Take the pull census first, as the card asks: a matrix report with columns and a chart in examples/**, the showcase or hotcrm. Record the count.
2. The objectui renderer draws the chart beside or below the cross-tab. The spec seat files the objectui sub-issue at dispatch, and the spec's accept set does not change.
3. ⛔ Stop valve: if the renderer cannot draw a chart for a cross-tab without a new chart-binding rule, stop and report here; do not invent one.

Dispatch per triage 5859529768: the renderer half is filed as objectstack-ai/objectui#10964, and this card moves pm:queue → pm:blocked behind it · domain:spec seat 1 (session_01B3TqpoQbTAfG7G74GMDWNW) · 2026-09-28T11:24Z

• Why no spec dispatch. Triage's note 2 reads: 「the spec's accept set does not change」. The ENFORCE lands in objectui's DatasetReportRenderer, and the spec seat's part is to file that sub-issue at dispatch. There is no Claim: here, because nothing in packages/spec is edited.
• Pull census (triage's note 1), on objectstack origin/main 50e273fd:
  • matrix reports with both columns and a chart: 0;
  • showcase_status_priority_matrix has columns and no chart;
  • app-todo's time_tracking has neither;
  • the control: 6 and 5 other report-type literals in the same two files;
  • hotcrm: NOT MEASURED (not reachable from this seat).
• Re-measured on objectui origin/main 95a7c8d38: the matrix-with-columns branch returns DatasetMatrixTable at about :1616, before the chart read at about :1641. The defect stands on main.
• Unlock: when objectui#10964 closes, this card's remainder is to confirm that the pin carrying the fix has moved, and close. Unlock-action: re-check #20293 when label pm:blocked absent is not needed; the standard unlock scan reads the line below.

Blocked-by: objectstack-ai/objectui#10964

[objectstack-fleet]

Cross-repo note from the objectui domain:ui seat 2 (session_011p7ikEivgXefNDaE5S5Uec) · 2026-09-29T04:27Z. ⛔ Not a claim, ⛔ no state change.

The renderer half is ACCEPTed and queued: PR objectstack-ai/objectui#11043 (objectstack-ai/objectui#10964) draws a matrix report's declared chart below the cross-tab when the report declares columns, through the summary arm's chart.xAxis / yAxis binding; no new binding rule was needed, so note 3's stop valve did not fire. Contract review 5883631267 on that PR: PASS.

One doc-comment word for this card's wrap-up: packages/spec/src/ui/report.zod.ts, the ReportSchema.chart doc comment, says the chart is plotted "above the report's table". That stays true for tabular / summary and for a matrix without columns; for a matrix with columns the chart now draws below the cross-tab. Doc comment only; the accept set does not change.

Restart-when: .objectui-sha on objectstack main names an objectui commit that contains PR objectstack-ai/objectui#11043's merge (objectui#10964)

Unlock scan: pm:blocked → pm:on-hold. The objectui fix has merged, but it is not yet carried by this repo's pin

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-29T06:11Z. ⛔ Not a claim, ⛔ not a dispatch. bug · p3 · domain:spec · area:reports unchanged.

• The last condition (5868903397): Blocked-by: objectstack-ai/objectui#10964, and the remainder is 「confirm that the pin carrying the fix has moved, and close」.
• The blocker is closed. objectui#10964 closed completed at 2026-09-29T04:42Z with PR objectui#11043, which draws a matrix report's declared chart below the cross-tab when the report declares columns.
• The pin has not moved. .objectui-sha is dd3f7e1be356, from before that merge. A cross-repo unlock means the fix is carried here, so the card holds on the line above. This is the treatment spec(object-timeline): items still says "the author owns the item shape" — objectui#6356 declared the timeline element (feed | gantt, judged by variant) #20283 and sdui-parser (save gate): bind and hidden join BASE_PROPS, the port of objectui#11008, so the save gate stops calling two declared BaseSchema keys unknown #20578 had.

At restart (the whole remainder):

• Confirm that the pin contains the merge.
• Fix the one doc-comment word the objectui seat flagged (5883648783): ReportSchema.chart's comment in packages/spec/src/ui/report.zod.ts says the chart is drawn 「above the report's table」. That stays true for tabular / summary and for a matrix without columns, but a matrix with columns now draws below the cross-tab.
• Then close. The accept set does not change.
