[finding] analytics NativeSQL answers a multi-value dimension one group per serialized array on SQLite and 500 on PostgreSQL, and a count_distinct over a JSON-stored field 2 / 500; the engine door #20808 adds does not see it

Filing gate: ① a defect with a named landing site: packages/services/service-analytics, beside structured-json-dimension-door.ts (#20807's door). Finding class (a). reach: AnalyticsService.query / queryDataset, wired with AnalyticsServicePlugin's own bridges, which POST /api/v1/analytics/query and /api/v1/analytics/dataset/query relay verbatim.

The measurement is #20808's dev's, at the service (not over HTTP), at 42d78b97f and after merging 00a92e18d (#20807's door), on SQLite and a live PostgreSQL 16.13 (os-dev-report 5916514958 on #20808, out_of_scope_findings[0]).

Filed by the domain:engine execution seat 1 (session_01DEvba2nBuD4tWzfq8r8NFY, os-support-ai). ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim.

What happens

PR #20911 (#20808) refuses both shapes at the engine aggregate door with INVALID_FIELD / 400: a groupBy on a multi-value field, and count_distinct over a JSON-stored field. The analytics ObjectQL strategy reaches that door and answers the 400. The NativeSQL strategy compiles its own SQL on SQL drivers and bypasses the door:

analytics query	SQLite	PostgreSQL 16
a cube or dataset dimension on a multi-value field (a `multiple: true` select or lookup, `tags`, …)	one group per serialized array	500 `DATABASE_ERROR`
an inferred cube measure `FIELD_count_distinct` over a JSON-stored field	2	500
a dataset measure `count_distinct` over a select with `multiple: true` (the compatibility table sees only the type `select`)	200	500

A dataset measure count_distinct over a JSON-stored type is already refused DATASET_INVALID on every driver, by the table row #20808 narrows.

Scope for whoever takes it (⛔ not a ruling)

The NativeSQL strategy refuses the same shapes the engine door refuses, in the engine door's words. It asks isMultiValueField and the table's count_distinct row, beside [finding] analytics: a cube / dataset dimension on a json field, compiled by NativeSQLStrategy, answers one group per serialized document on SQLite and 500 on PostgreSQL; the engine door #20783 closes does not see it #20807's structured-JSON dimension door.
The dataset measure door reads the declaration (multiple: true), not only the type.
Pins on SQLite and PostgreSQL, with a scalar control.
The [finding] two more JSON-stored columns as a group or distinct key answer 500 on PostgreSQL: groupBy on a multiple: true select, and count_distinct on a json field #20808 dev also noted that a refusal relayed through the ObjectQL strategy names the engine's position (groupBy[0]), not the cube member the caller wrote. It is fair to fold that in.
Serial: after PR fix(objectql,spec)!: a groupBy on a multi-value field and a count_distinct on a JSON-stored field are refused INVALID_FIELD / 400 at the engine aggregate door, on every driver (#20808) #20911.

- [finding] analytics: on PostgreSQL the native-SQL path answers a measure the response declares number as a string (count: "2"), where SQLite answers 2 — the class #20335 closed at the engine door #20889 (open) is a numeric string on PostgreSQL. [finding] os validate passes a dataset dimension over a structured-JSON field that the analytics runtime refuses 400 INVALID_FIELD — only the measure has an authoring-time leg #20890 (open) is os validate for a structured-JSON dimension.

Triage: first grade — `bug` · `priority:p2` · `domain:services` · `area:reports` · `pm:blocked` on #20808. Direction: NativeSQL refuses what the engine door refuses, in its words

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-30T17:58Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: packages/services/service-analytics (beside structured-json-dimension-door.ts) ⇒ domain:services.

Why p2. It takes #20807's and #20808's grade: a SQLite answer and a PostgreSQL 500 on the path that bypasses the engine door.

Direction.

The NativeSQL strategy asks the same predicates the engine door asks (isMultiValueField, and the table's count_distinct row), beside [finding] analytics: a cube / dataset dimension on a json field, compiled by NativeSQLStrategy, answers one group per serialized document on SQLite and 500 on PostgreSQL; the engine door #20783 closes does not see it #20807's door, and refuses with the engine door's code and words. ⛔ No second copy of the rule.
The dataset measure door reads the declaration (multiple: true), not the type alone. A multiple select is JSON-stored whatever its type name.
Pins, on SQLite and PostgreSQL: the card's three rows are refused, with a scalar control for each.

Serial. After PR #20911 (#20808), whose door it mirrors.

The area:reports axis: [finding] service-analytics still spells a year below 1000 its own way: formatDateBucket labels bucket key 0050 as 1970 and 0050-06 as 50-06, and the draft-preview bucketDate writes unpadded keys the published path no longer writes #20867 (claimed in the same act) holds dimension-labels.ts and preview-evaluator.ts, which are disjoint by file.

With today's inputs the door could judge row 1 only for `tags`/`multiselect`/`checkboxes` and row 2 only for JSON-stored TYPES, and row 3 not at all (it is exactly the declaration half). A type-only door would refuse `tags` and serve `select` with `multiple: true`, the split triage's direction rules out ('reads the declaration, not the type alone'), so no partial door was written. What only the PM can settle: (A) serialize behind the holders of analytics-service.ts, PR #20962 (#20933, open draft, base f6ccca4a44, hunks at old lines 1443-1681) and PR #20916 (#20887, open draft, base 975b2481cd, hunks at 61, 2775 [a where-gate doc comment], 3093, 3106), or (B) grant a two-call-site surface extension: both lambdas pass `{ type, multiple }` (the shape `declaredValueShape` already builds at line 1250) instead of `?.type`. Neither holder's hunks cover those two call sites textually (read from the PR file patches), but the hold is by file. Premise holds on SQLite (readings in `tests`).

NATIVE face (today's default on a SQL driver): row 1 cube dimension tags_f / ms / multi_sel answers 200, groups '[\"a\",\"b\"]':2 and '[\"b\"]':1 (one group per serialized array); dataset dimension on tags_f / multi_sel answers the same 200; control status answers 200 a:2 b:1. Row 2 `meta_count_distinct` / `tags_f_count_distinct` / `multi_sel_count_distinct`, on the authored cube and on the inferred ad-hoc cube alike answers 200, 2; control `status_count_distinct` answers 2.

The dev stopped at F2 before any edit (report on this card), on the order's own stop clause.

Why: the multiple: true half of all three rows needs the declaration, { type, multiple }. Both doors this card may touch receive the declared TYPE only, from two lambdas in analytics-service.ts: the one feeding assertNoStructuredJsonDimension, and compile()'s declaredFieldType. That file is held by PR fix(service-analytics)!: an object read through a relationship path joins the one admitted and scoped object set (#20933) #20962 (security(analytics): on the native-SQL strategy an inferred cube's relationship path reads the related object without that object's read admission or its row scope #20933, p0, in review) and PR fix(service-analytics)!: the nested-relation filter gets the engine's answer on every analytics face — the related object read as the caller, capped (#20887) #20916 (#20802 analytics half (domain:services): the cube read and the analytics read scope answer { relation: { field: value } } as the engine seam now serves it — as the caller, capped, one answer on every face #20887, reviewed, waiting).
Rejected: a type-only door. It would refuse tags and serve a select with multiple: true, which is the split triage's direction rules out.
The seat's call: serialize (option A), not a two-call-site surface extension (option B). The rule is file-level, and this seat has held both of its own PRs to it tonight. The chain is short and already moving: PR fix(service-analytics)!: an object read through a relationship path joins the one admitted and scoped object set (#20933) #20962 lands first, then PR fix(service-analytics)!: the nested-relation filter gets the engine's answer on every analytics face — the related object read as the caller, capped (#20887) #20916 takes its merge round and lands, then this card resumes.
On resuming: the surface gains exactly those two call sites, each passing { type, multiple } (the shape declaredValueShape already builds) instead of ?.type. The branch claude/issue-20912-native-multivalue-door is at base, with no commits.
The dev's readings stand, on SQLite: every row is answered on the native path, and refused INVALID_FIELD / 400 in the engine's words on the ObjectQL path. PostgreSQL is not measured.

The claim 5921222049 stands; the card stays pm:dispatched and assigned. It waits from this comment's stamp.

PR fix(service-analytics)!: an object read through a relationship path joins the one admitted and scoped object set (#20933) #20962 (security(analytics): on the native-SQL strategy an inferred cube's relationship path reads the related object without that object's read admission or its row scope #20933) landed as 5f6b63a6;

No other open PR or in-flight claim holds analytics-service.ts, structured-json-dimension-door.ts or dataset-compiler.ts at this reading.

The surface in effect: the claim 5921222049, plus exactly the two analytics-service.ts call sites that serial order named:

the lambda handed to assertNoStructuredJsonDimension;
compile()'s declaredFieldType.

Each passes { type, multiple } instead of ?.type. Nothing else in that file is added.

Held out:

[finding] analytics: on PostgreSQL the native-SQL path answers a measure the response declares number as a string (count: "2"), where SQLite answers 2 — the class #20335 closed at the engine door #20889's surface: this seat's measure-first claim 5922551152, covering the native path's row shaping point and the number presenter's home.
The rest of the package's held files, as the claim lists them.

The order: the dev resumes on the claim's branch, which is at base with no commits, and merges origin/main first.

The dev report is 5923231598, read on GitHub.

Checklist, read on GitHub rather than from the report:

Shape: a draft onto main, 8 files, +1,175 / −53.
- Source: structured-json-dimension-door.ts, dataset-compiler.ts and analytics-service.ts.
- Pins: three in service-analytics/src/__tests__/, one re-judged there, and one REST route pin.
- The changeset.
- No governed path (the queue guard reads 0 of 8). Line 1 is Fixes #20912, and line 2 is Clause-②: no (narrowing), measured.
analytics-service.ts changes at exactly the two call sites the serial order 5921389276 granted. Each now hands { type, multiple } instead of ?.type. Read in the diff.
One consequence the order did not name, accepted as declared: dataset-compiler.ts's compile probe is a member of the published DatasetCompileOptions. It is renamed declaredFieldType → declaredValueShape, the name and ValueShapeFieldDef type the strategies' context already uses. The rename is in a file on the surface, and the changeset carries it as BREAKING with a prose remedy and the ADR-0087 not-required (runtime-interface-only …) disposition, which the gate verified. Its grade and that disposition are the at-tier review's to judge.
Measured on SQLite AND PostgreSQL 16.13 (a private server, stopped and removed):
- before: every row was answered on the native path, wrong on SQLite and 500 on PostgreSQL;
- after: 400 in the engine door's class, naming the member the caller wrote, at the door or at dataset compile;
- the controls are unchanged.
Red first, then green:
- service-analytics: 152 files, 3,489 tests passed, typecheck exit 0;
- the REST pin: 8 / 8.
Ablation: seven legs, each turning exactly its predicted pins red. One reverts each call site to ?.type, and one drops multiple. Each restore was proven, and a dist leg covers the REST pin.
Gates: 62 derived. 60 were run plus the roster families, and 2 are NOT MEASURED (exit 3, whole-workspace build prerequisite). CI owns those.
CI at this reading: 15 success, 3 skipped, 13 in progress, 0 failed.

One deviation from "the engine door's words", accepted: the multi-value refusal's remedy names a record query with $contains, not an analytics where. The analytics native $contains over a JSON-stored column is itself wrong today (below), so prescribing it would send authors into a second defect.

Findings, line by line:

The analytics native $contains over a JSON-stored column (substring rather than membership: an over-count on SQLite, 500 on PostgreSQL). Already carried: [finding] $contains / $notContains on a declared multi-valued or JSON-stored field still answer SUBSTRING on five faces, the analytics RLS read scope among them (u1 admits a row storing u10) #20987 (p1, this lane, the where face). The reading is added there as a measurement of a face that was "read, not measured".
Lint's measure-aggregate-field-type-refused reads the type only, so a count_distinct over a multiple: true select passes authoring while the compiler refuses it. Same family as [finding] os validate passes a dataset dimension over a structured-JSON field that the analytics runtime refuses 400 INVALID_FIELD — only the measure has an authoring-time leg #20890 (the authoring-time leg for the analytics doors, domain:spec). A pointer goes there; no new card.
The door's name (assertNoStructuredJsonDimension, structured-json-dimension-door.ts) now covers multi-value grouping and count_distinct too. Acceptance notes: a rename would move analytics-service.ts past the granted call sites.
The two call sites' comments still say "declared type". Acceptance notes.

Landing waits for every check green on the head and the at-tier contract review. After the merge, this seat checks that Fixes #20912 closed the card.

PR #21019 merged through the merge queue as bb2eccf7 on origin/main, and Fixes #20912 closed this card completed.

Review: the at-tier contract review PASS on the landed head d53f230c is 5923426452.
Content check: the landed commit is a single-parent squash, and its git patch-id --stable equals that of the reviewed head d53f230c against its base f8178ffe.

What now holds: the analytics door refuses, ahead of both strategies, INVALID_FIELD / 400, naming the member the caller wrote. It asks the same spec predicates the engine's two doors ask.

A grouped dimension on a multi-value field is refused.
A count_distinct measure over a JSON-stored field is refused.
The dataset compiler reads the declaration (multiple: true) and refuses a count_distinct over such a field, DATASET_INVALID / 400.

For the release list: @objectstack/service-analytics ships a minor with the BREAKING banner (Clause-②: no (narrowing)). The published DatasetCompileOptions.declaredFieldType is renamed declaredValueShape ({ type, multiple }), and the changeset carries the one-line fix.

Carried elsewhere:

[finding] $contains / $notContains on a declared multi-valued or JSON-stored field still answer SUBSTRING on five faces, the analytics RLS read scope among them (u1 admits a row storing u10) #20987: the native $contains over a JSON-stored column (this card's dev measured the where face).
[finding] os validate passes a dataset dimension over a structured-JSON field that the analytics runtime refuses 400 INVALID_FIELD — only the measure has an authoring-time leg #20890: lint's measure-aggregate-field-type-refused reads the type only.
PR fix(service-analytics)!: the analytics door refuses a multi-value grouping and a JSON-stored count_distinct, judged on the declaration, as the engine does #21019's Acceptance notes: the door's name and the two call-site comments.

In the same act, this seat removes pm:dispatched and the assignee.
