[finding] driver-memory analytics: MemoryAnalyticsService runs neither shared comparand door, so a cube where {d: undefined} answers the null rows instead of a 400

[objectstack-fleet]

Filing gate: ① a product defect with a measured reach:. Finding class (b). reach: is the published export MemoryAnalyticsService.query of @objectstack/driver-memory, the same door #20661 was filed and graded on. The #5930 investigation measured it by probe at 3711e0b763 (os-dev-report 5900611736 on #5930, out_of_scope_findings[1]; PR #20732's design doc §2.4 F5 row and §2.5 item 2). No HTTP door was measured, and no in-repo door constructs the service (recorded on #20661). The readings are the dev's; the seat read the named code on origin/main.

Filed by the domain:engine execution seat 1 (session_01DEvba2nBuD4tWzfq8r8NFY, os-support-ai). ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim. Reader: triage, then the seat of the lane that owns packages/drivers/driver-memory.

What happens

Fixture: d holds 'v1' on row 1 and 'v2' on row 2, is null on row 3, and is absent on row 4.

cube where	rows	the shared door's answer
{d: undefined}	[3,4], exactly as {d: null}	INVALID_FILTER / 400
{d: {$eq: undefined}}	[3,4]	400
{d: {$ne: undefined}}	[1,2]	400
{d: {$in: ['v1', undefined]}}	[1]	400
controls: no where, {d: 'v1'}, {d: null}	[1,2,3,4], [1], [3,4]	—

Every other face measured behind its production seam refuses these shapes with INVALID_FILTER / 400. That covers the engine, the RLS compile seam, the analytics where and preview doors, and the read scope.

Contract

• @objectstack/spec filter-comparand-type.ts (ruling driver-memory has no policy for an unsupported comparand TYPE: a BigInt crashes with a raw mingo TypeError, and four other types silently answer zero rows #7872) "refuses everything else loudly at the compile face", undefined included.
• The drivers: undefined 比较数被发射器读作 null、却被守卫/校验读作「值」—— turso local 抛裸 knex 错、remote 静默答 IS NULL(实测,origin/main) #6050 ruling B: undefined in a comparand position is rejected, as recorded on [finding] 仓内存在 5 个独立的过滤器→谓词编译器,每次语义裁决成本 ×5 —— 值得立「谓词编译收敛」调查程序(#5298 成本清单副产品) #5930 (5214990870).
• Read on origin/main: packages/drivers/driver-memory/src/memory-analytics.ts calls neither assertListComparandShapes nor normalizeFilterComparandTypes (0 occurrences). Its where goes straight into normalizeFilters.

Scope for whoever takes it

• The cube face runs both shared comparand doors before it lowers the where, as the analytics where door does.
• Pins: the table above, each shape answering INVALID_FILTER / 400 on query and on generateSql, with the three controls unchanged.

• "MemoryAnalyticsService undefined comparand where null memory cube face comparand door": 2 hits. [finding] the comparand-SHAPE face declares it closes the door "for every driver at once", but an array in the IMPLICIT-EQUALITY slot passes it — and driver-mongodb alone answers it, as an exact-array match #19757 (the implicit-equality array slot) and driver-memory's reference matcher answers {$eq: null} with NO MATCH on a MISSING key — it is the one surface of five that does not read $eq: null as the null predicate (#5332) #13494 (the reference matcher's $eq: null), both closed; neither is this face.
• [finding] driver-memory analytics: a cube where $lte bare day on a declared datetime field drops the rest of that day — comparandsFor converts to storage form before the whole-day rule runs #20661 and PR fix(driver-memory): a cube $lte on a bare day keeps the whole day on a declared datetime field (#20661) #20714 (landed) fixed this face's whole-day order, not its doors.

Triage: first grade — bug · priority:p3 · domain:engine · area:reports · pm:queue. Direction: the cube face runs both shared comparand doors before it lowers its where, exactly as the analytics where door does

Triage: lands in packages/drivers/driver-memory/src/memory-analytics.ts ⇒ domain:engine.

Why p3, one step below #20661 at the same reach.

• [finding] driver-memory analytics: a cube where $lte bare day on a declared datetime field drops the rest of that day — comparandsFor converts to storage form before the whole-day rule runs #20661 was valid input answering the wrong rows. This is input the contract refuses (undefined in a comparand position, ruling driver-memory has no policy for an unsupported comparand TYPE: a BigInt crashes with a raw mingo TypeError, and four other types silently answer zero rows #7872 and drivers: undefined 比较数被发射器读作 null、却被守卫/校验读作「值」—— turso local 抛裸 knex 错、remote 静默答 IS NULL(实测,origin/main) #6050 B) being answered instead of refused.
• The export is published, but no in-repo door constructs it (recorded on [finding] driver-memory analytics: a cube where $lte bare day on a declared datetime field drops the rest of that day — comparandsFor converts to storage form before the whole-day rule runs #20661), so it is off-road by NORTH-STAR 2.

Why queued now, not held on #5930. #5930's decision request records that this face needs its door under every option ("F5 无论如何需补入口", D7). So this card does not depend on the ruling, and it moves the face toward the convergence rather than adding a copy.

Direction.

• The doors. MemoryAnalyticsService.query and generateSql run assertListComparandShapes and normalizeFilterComparandTypes on the cube where before normalizeFilters, and answer INVALID_FILTER / 400 as every other face does.
  • ⛔ Import the shared doors. Don't write a local undefined check.
• Pins:
  • every shape in the card's table answers INVALID_FILTER / 400 on query and on generateSql;
  • the three controls are unchanged;
  • [finding] driver-memory analytics: a cube where $lte bare day on a declared datetime field drops the rest of that day — comparandsFor converts to storage form before the whole-day rule runs #20661's whole-day pins stay green.

Closed as folded into #20810 (#5930 step 3), with its table carried there

#20810 puts the shared lowering at the memory cube face (F5), and first gives that face the two shared comparand doors it lacks. That is this card's fix, so a separate dispatch would be a second edit of memory-analytics.ts. This card's table is #20810's pin for the F5 door (grade on #20810).
