ObjectStackAdapter.aggregate() posts an un-lowered FilterArray as the analytics where — every array-form element:number / object-metric filter answers 400 on the runtime route; lower through parseFilterAST before the wire (moved from objectstack#15828, ruled 2026-09-05)

Provenance. Rebuilt here from objectstack-ai/objectstack#15828 (transfer is unavailable to the filing seat) after the maintainer's ruling of 2026-09-05, verbatim 「15828 按前端缺陷处理」 — recorded on that card by the director seat (objectstack-ai/objectstack#12708, summon #15). The objectstack card stays open, narrowed to the spec-side documentation half (D3 entry wording + one .describe() sentence). Measurements below are the source card's and triage's, re-read against objectui origin/main 81a2eb1f and the spec docblock on objectstack origin/main 6c439f2.

Symptom (user-visible today)

An element:number (array-only filter since objectstack#12039) or an object-metric authored with an array filter plus aggregate calls ObjectStackAdapter.aggregate() → analytics branch → POST /analytics/query with where = the array. The runtime route parses the body with AnalyticsQueryRequestSchema first (where: FilterConditionSchema) and answers 400 Invalid AnalyticsQuery body: where: … instead of the aggregate. Only the MongoDB-style record survives — the exact authoring form objectui#6206-B retired. Measured with safeParse on the spec source: record ACCEPT; AST tuple array / single tuple / rule array all REFUSE.

Why this is the adapter's defect and not the protocol's

@objectstack/spec data/filter.zod.ts, FilterArray docblock (objectstack#5158 ruling C), verbatim: "A FilterArray is not a storage shape and not a protocol shape. It is lowered to a FilterCondition at the single sink parseFilterAST (@objectstack/spec/data) the moment it arrives, and only the lowered FilterCondition travels any further. where on a query is a FilterCondition and stays one … no driver, no transport, no stored row — ever has to understand two filter dialects." Widening the wire was that ruling's rejected option A. The declared doors are React block props, FilterBuilder, and the REST $filter query string; a POST body's where is transport.

packages/data-objectstack/src/index.ts aggregate() (analytics branch, ~line 4990): payload.where = Array.isArray(params.filter) ? translateFilterArray(params.filter) : params.filter. translateFilterArray only normalises rule objects into AST tuples — the result is still a FilterArray. The protocol's lowering step is missing. The same file already imports isFilterAST from @objectstack/spec/data (line 21); parseFilterAST is exported beside it. The branch comment mistook service-analytics' in-process lowerAnalyticsWhere door (objectstack#5334) for the wire's door; objectui#6302's gate measured that function, not the route.

The fix

payload.where = Array.isArray(params.filter)
  ? parseFilterAST(translateFilterArray(params.filter))   // the protocol's single lowering sink
  : params.filter;                                        // record path unchanged

parseFilterAST returns undefined for an empty array — decide and pin: an empty authored filter posts no where (matches lowerAnalyticsWhere's "[] is no filter").
The find() path is untouched: it sends $filter on the query string, which is a declared door.
The spec-shape branch's UnloweredAggregateWhereError (objectui#6825, ruling 2026-08-30 option A) is a different branch and a different ruling; do not touch it.

Tests this must carry

packages/data-objectstack/src/aggregate-filter-lowering.test.ts re-pointed: the posted where for an array filter is a FilterCondition object (e.g. ['stage','=','won'] → { stage: 'won' } or whatever parseFilterAST yields — assert against parseFilterAST's own output, not a hand-written literal).
The route-hop pin both triage comments asked for: the built payload passes AnalyticsQueryRequestSchema.safeParse from @objectstack/spec/api — the exact gate the runtime runs — for a tuple, a logical group, a bare list, and the record form; and an infix join ([condA, 'or', condB]) is refused before the wire with the adapter's INVALID_FILTER envelope, not silently dropped.
Existing record-path tests stay green unchanged.

Out of scope

Widening AnalyticsQuerySchema.where; touching translateFilterArray's tuple normalisation; the dashboard-widget record producer (groupToCondition, objectstack#15829 family); any @objectstack/spec change (the documentation half lives on objectstack#15828).

Claim (os-dev, mode:subagent) — dispatched by the PM seat for this card only.

Session: session_01TezFG8ZMrNH6n5VTNpPpdH
Branch: claude/issue-7752-aggregate-where-lowering (pushed empty at claim time; base origin/main 81a2eb1f)
Worktree: /home/user/objectui-issue-7752
Domain: domain:ui

Read before claiming: this card's body and its one comment; objectstack#15828 body and all four comments (two triage comments, the maintainer ruling 5552626017 verbatim 「15828 按前端缺陷处理」, and the spec-half claim). The ruling is executed, not re-decided: the adapter is wrong, the protocol is right; ⛔ no widening of AnalyticsQuerySchema.where, ⛔ no @objectstack/spec change from this branch.

File surface I intend to touch: packages/data-objectstack/src/index.ts (the aggregate() analytics branch only, plus its stale comment about lowerAnalyticsWhere) · packages/data-objectstack/src/aggregate-filter-lowering.test.ts (re-pointed assertions plus the route-hop AnalyticsQueryRequestSchema.safeParse pin) · one .changeset/*.md (@object-ui/data-objectstack patch). ⛔ Untouched: translateFilterArray's body, the spec-shape branch and UnloweredAggregateWhereError / MalformedFilterError meanings, find()'s $filter door, packages/types, packages/core, and every governed surface (AGENTS.md, CLAUDE.md, .claude/**, docs/adr/**, root skills/**).

  "summary": "aggregate()'s ANALYTICS branch now lowers an array filter with parseFilterAST(translateFilterArray(filter)) before the payload is built, so the posted `where` is the FilterCondition AnalyticsQuerySchema declares; a record filter passes through unchanged. Empty case pinned as ruled: parseFilterAST([]) is undefined, so an empty authored filter posts NO `where` key (it used to post a literal []). An array the sink cannot lower (infix join [condA,'or',condB]; also a truncated tuple like ['stage','='] that isFilterAST accepts but the sink throws on) is refused with a new UnlowerableAnalyticsFilterError carrying the same INVALID_FILTER/400 envelope as MalformedFilterError and UnloweredAggregateWhereError, recognised by isMalformedFilterError() — never posted, never dropped. Neither sibling class's meaning was widened. The lowering runs BEFORE the analytics try block: raised inside it, a refusal would be classified `unknown` by classifyAnalyticsFailure and answered by the client-side fallback with plausible numbers. The branch comment no longer calls lowerAnalyticsWhere the wire's door and names the route hop instead. Verbatim premise check on origin/main confirmed every claim in the card: the un-lowered assignment at the named line, isFilterAST already imported from @objectstack/spec/data, parseFilterAST exported beside it, and the four safeParse verdicts (record ACCEPT; tuple/group/bare-list REFUSE un-lowered, ACCEPT lowered).",

chore(changeset): score #7752 as a minor — it adds a public export

os-dev-report addendum

Patch round, one item as dispatched: the changeset's bump was patch while the PR adds a public export (UnlowerableAnalyticsFilterError, present in dist/index.d.ts). Scored minor instead. Frontmatter only — the changeset text is byte-unchanged, and no other file moved.

new head sha: d4557b01 (a new commit on claude/issue-7752-aggregate-where-lowering, no amend, no force-push; previous head 00acc4a9 is its parent)
diff of this round: .changeset/7752-analytics-where-lowering.md, 1 file changed, 1 insertion(+), 1 deletion(-)
PR fix(data-objectstack): lower an array analytics filter through parseFilterAST before the wire (#7752) #7754 still draft, base main, auto-merge not armed

Gates re-run locally on d4557b01, exit codes captured by redirect and the verdict lines quoted from each gate's own output:

Command	Exit	Verdict line
`node scripts/check-changeset-presence.mjs`	0	`✅ 3 source file(s) of 1 released package(s) changed, and this change declares 1 changeset(s): .changeset/7752-analytics-where-lowering.md.`
`node scripts/check-changeset-no-major.mjs`	0	`✅ No changeset declares a` major `bump.`
`node scripts/check-changeset-fixed.mjs`	0	`✅ privatePackages declared: version=true, tag=false.`

The third row is this repo's fixed-group bump-policy gate (changeset-guard.yml runs it beside no-major). One gate beyond the three asked for, run because it is the other half of that workflow and it bears on the earlier reported near-miss: node scripts/check-changeset-overwrite.mjs exits 0 with ✅ No pre-existing changeset was modified or deleted. — independent confirmation that the clobbered .changeset/lucky-donkeys-shave.md was fully restored and that nothing this branch carries touches a changeset it does not own.

Nothing else was touched: no source, no test, no governed surface, and the PR was not flipped out of draft.
