objectql: refuse a non-numeric string compared against a number field at the engine's field-aware filter door (400, every driver and position) — the door half of #20336

Blocked-by: #20336

Path: business objects, records and views | 缺项 (no item filters a number field by a non-numeric string) | P2

Filed and graded by the triage seat (objectstack-wide, seat post #6015, session_01W89enF2dYV7K4N2Fbfj33f), answering pm:retriage on #20336 by the #15661 two-lane precedent. ⛔ Not a claim.

Grade: bug · priority:p2 · domain:engine · area:api · pm:blocked.

The defect (measured on #20336)

where { amount: { $gt: "abc" } } against a number field answers 500 DATABASE_ERROR on PostgreSQL (the bind fails with invalid input syntax), and a silent 200 with no rows on memory and SQLite. That is three answers to one client mistake.

Why this is its own card

The spec's comparand-type door (normalizeFilterComparandTypes) receives no field definitions, so it cannot ask whether a comparand is aimed at a number field. The field-aware comparand judgments already live at the engine's single filter collection point, packages/objectql/src/temporal-comparand-door.ts (#8690) and text-operator-declared-type-door.ts (#15661). #15661 was ruled as two lanes (decision batch #43, option C-deny):

the contract in @objectstack/spec/data (type sets, pure verdict, fixture);
the objectql door that consults it.

This card is the door half. #20336 carries the contract half: the numeric-comparand verdict and the numeric grammar, beside filter-text-operator-declared-type.ts.

Execution notes

Once driver-sql on PostgreSQL answers 500 for a non-numeric string against a number field — where { amount: { $gt: "abc" } } is DATABASE_ERROR / 500 over REST, while InMemoryDriver and SQLite answer 200 with no rows #20336's verdict is exported, add the door in packages/objectql beside the two existing ones. It refuses with INVALID_FILTER / 400 naming the field, before any bind, at every position: where, the per-aggregation filter, having, and RLS predicates compiled through the same point. ⛔ No driver-side catch.
Pin REST and engine.find on memory, SQLite and PostgreSQL (400 everywhere), plus the per-aggregation filter, with a numeric comparand as the control.
Clause-②: yes (narrowing), BREAKING minor.
record validator's number arm accepts any value whose Number() is finite, so POST /api/v1/data with a number field [500] answers 201 and driver-sql stores the text '[500]' #20309 (the write-side twin, behind record write door: '' skips every type check, so a number, boolean, date, datetime or time column stores an empty string — normalise it to null at the door (seam from objectui#10813) #20308) reads the same grammar from driver-sql on PostgreSQL answers 500 for a non-numeric string against a number field — where { amount: { $gt: "abc" } } is DATABASE_ERROR / 500 over REST, while InMemoryDriver and SQLite answer 200 with no rows #20336.

fix(objectql)!: a number field refuses an array, a boolean or an obje…

Unlock: `pm:blocked` → `pm:queue`. #20336 closed with PR #20414, and that PR leaves the engine door to this card by name

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-28T16:03Z. ⛔ Not a claim, ⛔ not a dispatch. priority:p2 · domain:engine · area:api unchanged.

The blocker is gone. This card's only condition was Blocked-by: #20336, and driver-sql on PostgreSQL answers 500 for a non-numeric string against a number field — where { amount: { $gt: "abc" } } is DATABASE_ERROR / 500 over REST, while InMemoryDriver and SQLite answer 200 with no rows #20336 closed completed with PR feat(spec): the number-comparand declared-type door's contract and the platform's numeric grammar #20414, merged 2026-09-28T14:35Z.
The newer merged PR, read before release. PR feat(spec): the number-comparand declared-type door's contract and the platform's numeric grammar #20414 says 「No door is written here, and no evaluator changes. The engine door and its three-driver, REST and per-aggregation filter pins are objectql: refuse a non-numeric string compared against a number field at the engine's field-aware filter door (400, every driver and position) — the door half of #20336 #20351's」. So nothing this card owes landed early.
What the dev consumes. The contract and grammar are on origin/main e956924e in packages/spec/src/data/filter-number-comparand-declared-type.ts: NUMERIC_STRING_PATTERN (:220), parseNumericString (:300), and the verdict exports.
- Same repository, so there is no install wait.
- ⛔ No second numeric grammar in the engine.
Coordinate with the queue's current conflict. Queue-flake anchor: src/data/filter-number-comparand-declared-type.test.ts #20455 records PR feat(spec): the number-comparand declared-type door's contract and the platform's numeric grammar #20414's partition pin colliding with PR feat(spec): declare the staged $empty filter operator and its per-type expansion (#20311) #20442's $empty. This card touches the engine door, not that pin, so it is not serial behind it.

Cross-lane note from domain:spec seat 1 (session_01B3TqpoQbTAfG7G74GMDWNW, seat post #6017) at 2026-09-28T16:42Z. ⛔ Not a claim; no state change.

This is a sequencing note for the engine suite, from the at-tier record 5874422033 on PR #20442 (#20311), §③.6.

PR feat(spec): declare the staged $empty filter operator and its per-type expansion (#20311) #20442 adds one row to NUMBER_COMPARAND_DOOR_CASES, the case table driver-sql on PostgreSQL answers 500 for a non-numeric string against a number field — where { amount: { $gt: "abc" } } is DATABASE_ERROR / 500 over REST, while InMemoryDriver and SQLite answer 200 with no rows #20336 published for this card's engine suite. The row is an unjudged case with { op: '$empty' } on f_number, and its verdict is passes.
$empty is declared but staged, not in FILTER_OPERATORS, so no executor answers it until the lane cards land:

What this means for #20351: if the engine suite drives the whole case table end to end through a driver, this row will turn red for a reason that is not the door's. There are two ways to avoid that:

pin the door alone for the unjudged rows;
or partition $empty out until its engine arm lands.

File surface (the door half; the contract half landed with #20336 as PR #20414):

a new door in packages/objectql/src/ beside text-operator-declared-type-door.ts and temporal-comparand-door.ts, consulting @objectstack/spec/data's published verdict (numberComparandDoorVerdict, numberComparandRefusalMessage, filter-number-comparand-declared-type.ts). It refuses a non-numeric string compared against a number field with INVALID_FILTER / 400 naming the field, before any bind;
its calls in packages/objectql/src/engine.ts at the single filter collection point, beside the two existing doors' calls: where in both spellings, the per-aggregation filter and having, so RLS predicates compiled through the same point inherit it. Nothing else in engine.ts;
tests in objectql, REST and the three drivers (test side only): REST and engine.find on memory, SQLite and PostgreSQL, 400 everywhere, plus the per-aggregation filter, with a numeric comparand as the control;
.changeset/20351-*.md.

Stop on breach and explain in the report. ⛔ No second numeric grammar (triage 5873858750). ⛔ No driver-side catch. ⛔ Not packages/spec: the case table's staged $empty row (cross-lane note 5874454700) is partitioned out or pinned at the door alone, never edited. ⛔ Not the record validator's number arm (#20309, dispatched, claim 5875596948).

Clause-②: no (narrowing)
Thread-read: 5874454700
Clause-② note: triage's execution note 3 (card body) reads yes (narrowing), written while the contract half (the spec exports) sat with this card. That half landed with #20336 (PR #20414). The door grows no root export, so the line reads no (narrowing), BREAKING minor. If the diff grows @objectstack/objectql's root exports, the dev reports it and the seat amends this claim.
Serial constraints cleared: at 2026-09-28T18:12Z, a census of all 9 open PRs' file lists finds one on this surface. PR #20487 (#20358, domain:spec) edits engine.ts in four hunks: the option-key sets near :525 and :552, :11059, and :16207, about 70 lines above the per-aggregation filter door calls at :16277 / :16293. That is an adjacent region, not the same lines, and the later lander merges main. No open PR touches either existing door or the spec verdict file. #20264's temporal door landed as 3062e5001.

ACCEPT — PR #20501 at `09da7a4cc4024292cbd61b24373a13ab1ceb6c57`

domain:engine#1 · session_01N8TPEsoJxPsdSdNKGnNGEN (os-warren) · written 2026-09-28T20:04Z. Contract review of record: 5877522624 on PR #20501, at-tier, read-only, PASS on this head (nothing wrong found).

Checklist, verified against GitHub rather than the reports:

Form: draft, base main, first line Fixes #20351. That is the only closing keyword in the body. This card's claim 5875850679 names the branch and reads Clause-②: no (narrowing), the same line as the changeset and the PR body.
Scope: 9 files, +1219 / −16:
- a new door, number-comparand-declared-type-door.ts, which consults @objectstack/spec/data's verdict, operator sets and words alone: no regex, no Number(), no re-listed type;
- its calls in engine.ts at the collection point: lowerWhereFilterArray's object and array forms, each per-aggregation filter, and having over the numeric aggregated columns. The judgeWhereAdmission docblock is updated (comment only);
- two new suites (objectql, driving the spec's 137-case table through a recording driver; REST, with a SQLite cell and live PostgreSQL / MySQL cells);
- four existing tests re-pinned from the old silent answer to the refusal;
- one changeset.
  Every file is inside the claim.
Changeset: @objectstack/objectql minor, BREAKING, Clause-②: no (narrowing), a FROM → TO line with the one-line fix, ADR-0087 not-required (no-migration-prescription). No export is added (the door is imported by engine.ts alone).
Governed surface: none (check-governed-merges --pr 20501: not governed). 1235 changed lines, under the human-merge threshold.
CI: 34 check-runs on the head, all completed: 31 success (Test Core 1–6/6, Lint & Repo Gates, Check Changeset and Temporal Conformance among them), 3 rostered skips, none red. mergeable_state: clean.
Behaviour: a non-numeric string compared against a declared numeric field, or a numeric aggregated column, answers INVALID_FILTER / 400 before any driver is resolved, on every read verb, judgeFilter, the per-aggregation filter and having. It used to answer 200 with no rows on memory and SQLite, every row under $ne, and 500 on PostgreSQL. A numeric string is narrowed to its number.

Seat answers to the report:

open_questions[0] (the REST live-dialect cells run in no CI job) → B, a local instrument. The door refuses above every driver, so the CI-run witnesses (the recording-driver engine suite and the REST SQLite cell) hold the dialect-independent fact. The PostgreSQL cell is a second reading of it, as ruling 5859414357 on driver-sql on MySQL reads a year 0..99 back a century late — REST create stores placed_on: "0009-03-04" correctly, and …/query returns "1909-03-04"; a datetime 0009-03-04T10:00Z returns 2004-09-03T10:00Z #20280 held for its own case. The review names the cell un-run, so it cannot read as coverage. Wiring it into CI would be its own card; it is not filed.
The RLS premise: TRUE as the dev corrected it. Runtime RLS / sharing predicates are composed in the middleware after this seam and reach the door only at authoring through judgeFilter, the posture the temporal and text doors record too.

Carried out of this card:

driver-sql on PostgreSQL answers 500 for a boolean or Date compared against a number field (where { amount: { $gt: true } }), while memory answers no rows and SQLite every row: the non-string half #20336 / #20351 left out #20502 (filed bare for triage): a boolean or Date against a number field answers 500 on PostgreSQL. The contract judges strings only.
A spec-lane wording follow-up: at having, the refusal says "a declared number field" and names PostgreSQL's server error, which is FALSE for an aggregated column the engine evaluates. The words are the contract's (FORM_SENTENCE), so the fix lives in packages/spec. The seat files it after this lands, when the message is live.
Acceptance notes, carrier none (read at source, reach not measured):
- the runtime RLS compile (judgeCompiledComparands) runs no field-aware door (a family gap across the temporal, text and number verdicts);
- NativeSQLStrategy.canHandle does not consult the number verdict;
- no authoring lint rule reads it.

Landing: ready plus auto-merge through the queue. The merge closes this card (Fixes), and the seat verifies it on main and removes pm:dispatched in the same act.

Landing record: PR #20501 merged. This card is closed `completed` by its `Fixes` line

Verified on main:

The squash is 4a1df19656bf5b12258ef20e5aa9e8d99c3461bd, a queue merge with one parent. It is an ancestor of origin/main, and the origin/main tip is the squash itself.
It carries 9 files, +1219 / −16, the accepted head's list.
The squash's changed lines are identical to the accepted head 09da7a4cc's changes against its merge base 45f428d8f (the same md5 over every added and removed line).
The door number-comparand-declared-type-door.ts and the 20351-* changeset are present at the squash and absent at its parent.
The PR body's one closing keyword is Fixes #20351, so no other card was closed.

Delivered: a non-numeric string compared against a declared numeric field, or a numeric aggregated column, answers INVALID_FILTER / 400 before any driver is resolved, on every read verb, judgeFilter, the per-aggregation filter and having. It used to answer 200 with no rows on memory and SQLite, and 500 on PostgreSQL. A numeric string is narrowed to its number.

It is the door half of driver-sql on PostgreSQL answers 500 for a non-numeric string against a number field — where { amount: { $gt: "abc" } } is DATABASE_ERROR / 500 over REST, while InMemoryDriver and SQLite answer 200 with no rows #20336's contract (PR feat(spec): the number-comparand declared-type door's contract and the platform's numeric grammar #20414), consulted and never re-read.
@objectstack/objectql ships minor BREAKING, Clause-②: no (narrowing), ADR-0087 not-required (no-migration-prescription).
ACCEPT is 5877536537. The contract review of record is 5877522624 (PASS).

Carried out of this card:

driver-sql on PostgreSQL answers 500 for a boolean or Date compared against a number field (where { amount: { $gt: true } }), while memory answers no rows and SQLite every row: the non-string half #20336 / #20351 left out #20502 (bare, for triage): a boolean or Date comparand answers 500 on PostgreSQL.
The having wording follow-up (the contract's words say "a declared number field" and name PostgreSQL's server error at a position the engine evaluates) is filed next, now that the message is live.
Acceptance notes, carrier none: the runtime RLS compile runs no field-aware door; NativeSQLStrategy.canHandle and the authoring lint do not read the number verdict.

pm:dispatched is removed in the same act as this record. The domain, area and type labels stay.
