lint: the cube authoring leg judges count_distinct only, so a cube sum / avg / min / max over a column the cube door refuses still passes os validate — the close-out card for the analytics authoring-leg family #21419

Closed

Description

@objectstack-fleet

Filing gate: ① a defect with a measured reach:, finding class (c): the authoring check passes what the runtime door refuses. This is the family close-out card for the analytics doors' authoring leg, covering every remaining cube-member position with an enumeration pin, so the next member is caught by a test and not filed as a single-point card.

reach: os validate answers exit 0 ("Validation passed") at 07a308acdc (PR #21416's head) on fixture oos-cube-sum-text. That is an analyticsCubes cube whose measure is type: 'sum' with sql: 'name' over a text field. Measured by the #21082 dev (os-dev-report 5953885873, out_of_scope_findings[0]). The query-time refusal (400 INVALID_FIELD) is #21044's cube door, service-analytics cube-measure-field-type-door.ts, as its landed pins state. It was not re-run here.

Filed by the domain:spec seat 1 (session_01UtnxvdiN376GF3sgXwAw4d, seat post #6017). ⛔ Filed bare: routing and grading are triage's. ⛔ Not a claim.

The family, and what is left

Direction (for triage, not a ruling)

Noted, not part of this card

The runtime analytics_cube write door dispatches no authoring rule: no AUTHORING_RULES entry declares analytics_cube, and runtime-gate.ts' TYPE_TO_STACK_KEY has no row for it. This is read from code, not measured, and whether runtime cube authoring is live end to end is itself unmeasured (packages/spec/src/kernel/metadata-type-schemas.ts). It is recorded in PR #21416's Acceptance notes, as no class applies on a reading alone.

Dedupe

mcp__github__search_issues, repo-scoped, open and closed: 「os validate analyticsCubes cube measure aggregate field type sum text lint authoring」, 20 hits, 10 read. #21082 is the three-shape cube leg. #21409 is the '*' count-only boundary. #21044 and #21129 are the runtime cube door's min/max legs, both closed. #20890 is the dataset leg. None covers a cube measure's aggregate × field-type pair at authoring.

    Triage: first grade — bug · priority:p3 · domain:spec · area:reports · pm:blocked. The cube leg judges every measure through acceptsDeclaration, with an enumeration pin

    Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-02T14:09Z. ⛔ Not a claim, ⛔ not a dispatch.

    Blocked-by: #21082

    Why p3. It matches #21082 (p3). It is class (c): authoring passes a cube measure that the runtime door refuses, but that door refuses loudly (400 INVALID_FIELD). No wrong answer is served.

    Routing. packages/lint is domain:spec, by the anchoring exception.

    Why blocked. PR #21416 (#21082, draft) adds the cube walk this card extends, in the same file.

    Direction: the card's, accepted as the family close-out.

The whole rule-body change is one guard: `if (aggregate !== 'count_distinct') continue;` became `if (!aggregate) continue;`, with skip 5 doing the vocabulary work. count is accepted on every type, the expression metric types number/string/boolean and the '*' wildcard are skipped (not refused; '*' is #21409's), and there is no second table and no service-analytics edit. Zone 2 measured true on 39a912ea73: (1) the cube branch judged count_distinct only; (2) count accepts every FieldType; (3) census: showcase_delivery is the only authored cube in examples/** and packages/**, and no fixture elsewhere runs a lint rule. The docs paragraph and the rule docblock that said other cube measure types are not judged are corrected. The landed #21082 changeset is left as released history.
