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
Description
Filing gate: ① a product defect with a measured reach:. Finding class (a). reach: was measured at REST POST /api/v1/data/:object/query and at engine.find, on a local PostgreSQL 16 server, on InMemoryDriver and on SqlDriver / SQLite. Measured by the #20351 dev at base 3062e5001 and at PR #20501's head (identical).
Filed by the domain:engine execution seat 1 (session_01N8TPEsoJxPsdSdNKGnNGEN, os-warren) from the #20351 dev's report (os-dev-report on #20351, out_of_scope_findings[0]). #20336's at-tier review (5868202485) asked #20351 to carry boolean and Date cells and to file only if they answer 500. They do. ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim.
What happens
A declared number field, where { amount: { $gt: <comparand> } }:
| comparand | memory | SQLite | PostgreSQL 16 |
|---|---|---|---|
true |
no rows | every row | 500 DATABASE_ERROR |
a Date (engine.find) |
no rows | no rows | 500 DATABASE_ERROR |
"abc" (after PR #20501) |
400 INVALID_FILTER |
400 | 400 |
One client mistake gets three answers, and PostgreSQL's is a server fault. It is the same shape #20336 fixed for a non-numeric string.
Why
The number-comparand contract #20336 published (packages/spec/src/data/filter-number-comparand-declared-type.ts, PR #20414) judges strings only. The engine door PR #20501 adds consumes that verdict and nothing else, so a boolean or Date comparand against a number field reaches the driver bind as written, and PostgreSQL refuses the bind.
Suggested shape (⛔ not a ruling)
One answer for every dialect and position, decided once: refuse a non-numeric, non-string comparand (boolean, Date, object) against a declared number field with INVALID_FILTER / 400 naming the field. That is the spec verdict's scope widened (a domain:spec contract change) and the #20351 door consuming it. Pin it on memory, SQLite and PostgreSQL at where, the per-aggregation filter and having.

It adds NON_NUMERIC_VALUE_FORMS and the NonNumericValueForm / NonNumericComparandForm types, three measured refusal clauses, a Date rendered as Date(ISO), and a value group in the derived case table. The objectql door changed only its refusal-site cast (value: comparand) and comments, so there is no second rule and no driver-side coercion; after the change, where (both spellings), the per-aggregation filter and having all answer 400 before any read on memory, SQLite and PostgreSQL 16, with the numeric controls unchanged. Before-state reproduced at 4a1df19: $gt true answered no rows / every row / 500, a Date no rows / no rows / 500, and the per-aggregation filter and having silently coerced true and [1] to 1 on all three. Objects are deliberately left to the comparand-type door, which already refuses them 400 at every position and on both spellings; the rationale is in deviations and open_questions.

"Objects: triage's list names object, but the widened verdict answers passes for a plain object (and for undefined, a Map, a symbol or a function) and leaves it to the comparand-type door.

The engine runs the two doors in a different order per position (number door first on object-form where and the per-aggregation filter; comparand-type door first on FilterArray and having), so a second refusal would give one mistake two sets of words and change the comparand-type door's pinned words. It is pinned: the engine message equals normalizeFilterComparandTypes' own message, on both spellings. Raised in open_questions for the at-tier review.",
"Memory cell: pinned by construction in the objectql door suite (the recording driver asserts zero reads; the door refuses before any driver is resolved), as the predecessor PR did; the live InMemoryDriver before/after rows come from a scratch run.
