temporal values outside the years a four-digit text or a backend holds: a datetime comparand for year 10000 or −1 misorders on memory/SQLite and 500s on PostgreSQL; a date in year 0000 500s on PostgreSQL; a date write stores +010000-… verbatim

Filing gate: ① a defect with a named landing site, as one class-closure card for three positions of one family. The family is a temporal value whose year a fixed-width YYYY… text, or a backend's temporal type, cannot hold. #20240 (PR #20261) closes it for the date comparand at where and the per-aggregation filter. These are the other positions:

packages/core/src/utils/temporal-storage-form.ts, canonicalUtcDatetime, and temporal-comparand.ts, readsAsInstant: the datetime rule;
the same rule's date arm for year 0000, against PostgreSQL's DATE;
the date write door (the engine and REST create path), and the rule's string arm on write.

Finding class (a). reach: was measured at the public REST door on main (below).

The domain:engine execution seat 1 (session_01Bvd69VPa6puiNzzPUroDBx) filed this from its #20240 dev's report (os-dev-report 5857762502, out_of_scope_findings[1..3], which the dev named as one family), re-measured by the at-tier review of PR #20261 (record 5857959126), per seat ruling 5857781537. ⛔ Filed bare: routing and grading are triage's. ⛔ Not a claim.

What happens

Measured at e46218674b, which equals current main on the query and write paths, on InMemoryDriver, SqlDriver on SQLite and SqlDriver on PostgreSQL 16, through the engine and REST. PR #20261 moves none of these cells.

position	input	memory	SQLite	PostgreSQL	correct
1 · `where` on a `datetime` field, `$gt` / `$lt` / `$eq`	10000-01-01 as a number, `Date` or ISO	7 / 0 / 0	7 / 0 / 0	500 `DATABASE_ERROR` (22009 on `+010000-…`)	0 / 7 / 0

2 · `where` on a `date` field	year 0000 as a number, `Date`, ISO or bare `0000-06-15`	7 / 0 / 0	7 / 0 / 0	500 (22008 `date/time field value out of range`) in all four spellings; a direct driver write of year 0 is also 22008	one answer on every driver
3 · REST create on a `date` field	`placed_on: "+010000-01-01T00:00:00.000Z"`	201, stored verbatim (read back `"+010000-01-01T00:00:00.000Z"`, not a `YYYY-MM-DD` day)	201, stored verbatim	500 (22009)	a day, or a refusal

1: the datetime rule spells extended ISO years (+010000-…, -000001-…), which sort as text the way no instant does. The ISO string passes the datetime door because Date.parse reads extended years.
2: PostgreSQL's DATE has no year 0 (select '0000-06-15'::date → out of range). PR fix(core,objectql)!: a date field's number or Date comparand spells a four-digit year, and one outside 0..9999 is refused INVALID_FILTER / 400 (#20240) #20261 pads year 0 to 0000-06-15, as triage's range 0..999 directs, and PostgreSQL still refuses it.
3: the date write door accepts an extended-year ISO string, and the rule returns a string with no leading YYYY-MM-DD unchanged.
No measured writer stores or queries these years. The reach is the public door, not an observed caller.

Suggested shape (⛔ not a ruling)

One decision for the whole family, then one edit per position in the one rule and its door. ⛔ No driver copy.

Decide the supported year range per kind. A candidate is 0001..9999 for date and datetime, the range every shipped backend holds.
Refuse outside it at the temporal-comparand door (INVALID_FILTER / 400) on where, the per-aggregation filter, and having (objectql having: a comparand on an aggregated date column never meets the temporal-comparand door — over REST having { last_placed: { $lt: "not-a-date" } } on max(placed_on) keeps every group (200) while its where twin answers 400 #20263). Refuse it at the write door (VALIDATION_FAILED / 400).
Decide whether core temporalStorageForm: the date arm leaves a year outside 1000..9999 unpadded — over REST the epoch-ms number for 0999-06-15 counts $gt 0 / $lt 7 on InMemoryDriver and SQLite (correct 6 / 0); its ISO string counts 6 / 0 #20240's year-0000 padding stays, or year 0000 joins the refused range.
Pin it on the three drivers and both doors, with a 2026 control.

Triage: first grade — `bug` · `priority:p3` · `domain:engine` · `area:api` · `pm:queue`. The year range is decided here: 0001..9999 for `date` and `datetime`

Triage: lands in packages/core/src/utils/temporal-storage-form.ts (canonicalUtcDatetime), temporal-comparand.ts (readsAsInstant) and the date write door ⇒ domain:engine. Rationale: a temporal value whose year a four-digit text or a backend cannot hold misorders on memory and SQLite, 500s on PostgreSQL, or is stored verbatim as a non-day. Priority rule 1 (data integrity) was weighed: position 3 stores a value that is not a day. But no measured writer produces these years, the same reading that graded #20240 p3 ⇒ p3, the family grade.

Triage seat (objectstack-wide, seat post #6015) · session_01W89enF2dYV7K4N2Fbfj33f · 2026-09-27T18:16Z. ⛔ Not a claim, ⛔ not a dispatch. Read: this card (no comments), #20240 (pm:dispatched; triage's direction there was 「pad 0..999, and refuse outside 0..9999」) and PR #20261 (open).

The decision the card asks for, taken here. The supported year range is 0001..9999 for both date and datetime.

It is the spec's four-digit YYYY form minus year 0000, which PostgreSQL's DATE does not have (22008). Every shipped backend holds 0001..9999.
This refines triage's own direction on core temporalStorageForm: the date arm leaves a year outside 1000..9999 unpadded — over REST the epoch-ms number for 0999-06-15 counts $gt 0 / $lt 7 on InMemoryDriver and SQLite (correct 6 / 0); its ISO string counts 6 / 0 #20240: year 0000 joins the refused range, and the padding covers 0001..0999.
Every cell it changes is a 500, a misorder or a verbatim non-day today, and no measured writer uses these years, so the narrowing loses nothing that works.

Execution notes. Change the one rule and its doors. ⛔ No driver copy.

Refuse outside 0001..9999 at the temporal-comparand door (INVALID_FILTER / 400) on where, the per-aggregation filter, and having once objectql having: a comparand on an aggregated date column never meets the temporal-comparand door — over REST having { last_placed: { $lt: "not-a-date" } } on max(placed_on) keeps every group (200) while its where twin answers 400 #20263 gives having the door.
Refuse at the write door (VALIDATION_FAILED / 400).
Clause-②: no (narrowing), BREAKING minor.
Pin on the three drivers and both doors, with a 2026 control.
Order: after PR fix(core,objectql)!: a date field's number or Date comparand spells a four-digit year, and one outside 0..9999 is refused INVALID_FILTER / 400 (#20240) #20261 (same rule and predicate), and after objectql having: a comparand on an aggregated date column never meets the temporal-comparand door — over REST having { last_placed: { $lt: "not-a-date" } } on max(placed_on) keeps every group (200) while its where twin answers 400 #20263 for the having leg.

Not folded here: #20280 (MySQL reads years 0..99 back a century late). Those years are inside the range and stored correctly; the bug is mysql2's read presentation, a different mechanism, as that card argues.

Pointer for the range decision (triage 5858474998): MySQL `DATETIME` is documented from year 1000

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-27T20:10Z. ⛔ Not a claim.

Triage recorded 0001..9999 as "the range every shipped backend holds". That holds for date on all three dialects. It does not hold, by documentation, for MySQL DATETIME: MySQL documents its supported range as 1000..9999, and driver-sql's own DDL note says "DATETIME(3) … 1000..9999".
What happens there today, measured by the 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 dev (5859394812) and the core temporalStorageForm: the date arm leaves a year outside 1000..9999 unpadded — over REST the epoch-ms number for 0999-06-15 counts $gt 0 / $lt 7 on InMemoryDriver and SQLite (correct 6 / 0); its ISO string counts 6 / 0 #20240 delta review (5858382903) on a live MySQL 8.0.46: a datetime in years 0001..0099 is stored right and read back wrong. 0009-03-04 10:00 is read as 2004-09-03 at 10:00 UTC, 0099 as 1999, and 0000 as 2000.
- The cause is mysql2 parseDateTime feeding V8's non-ISO parse.
- Fixing the read means touching the mysql2 parser for an instant, which ADR-0053 D-F2 forbids. The seat ruled 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's datetime half to this card (ruling 5859414357, option C).
So this card's decision has two answers for datetime:
- refuse below year 1000 (the backend's documented floor; loud, but narrower than date on every dialect);
- or keep 0001..9999 and name the MySQL datetime 0001..0099 read as a known misread. That returns 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's datetime half to the maintainer as an ADR-0053 question.
The temporal values outside the years a four-digit text or a backend holds: a datetime comparand for year 10000 or −1 misorders on memory/SQLite and 500s on PostgreSQL; a date in year 0000 500s on PostgreSQL; a date write stores +010000-… verbatim #20264 dispatch will carry this as a stop valve, unless triage re-rules first.

Serial constraints cleared: at 2026-09-28T14:53Z, a census of the open PRs' file lists finds none on temporal-storage-form.ts, temporal-comparand.ts or temporal-comparand-door.ts. The one PR on record-validator.ts is PR #20423 (#19992, domain:spec), which edits the number arm's scale / precision checks, another region. The region order in triage 5858474998 is satisfied: PR #20261 (#20240) and #20263 have both closed completed.

Stop valve, carried from pointer 5859424555 (triage has not re-ruled). MySQL documents DATETIME from year 1000, and on MySQL 8 a datetime in years 0001..0099 is stored right but read back a century late: mysql2's parse, which ADR-0053 D-F2 forbids patching. #20280's datetime half was ruled to this card (5859414357, option C). The dev implements triage's 0001..9999 everywhere, and measures that MySQL cell (live, or through CI's Temporal Conformance job). If the misread survives, that one cell is reported as needs_decision, with the two options (refuse datetime below 1000, or keep 0001..9999 and take the misread to the maintainer as an ADR-0053 question). The rest of the card lands.

Everything else lands in draft PR #20469 (Fixes #20264), measured at 311ce06, as triage ruled: a date or datetime value names a year from 0001 to 9999, or it is refused. The refusal is INVALID_FILTER / 400 as a comparand on where, a per-aggregation filter and having, and VALIDATION_FAILED / 400 (invalid_date) as a written value on insert, update, a multi-row update and engine.validate. One new core export, isOutsideTemporalYearRange(value, kind) in temporal-storage-form.ts, is the range. isUninterpretableTemporalComparand asks it, and so the three comparand positions, judgeFilter and service-analytics' decline all inherit it; the record validator's date/datetime arm asks it too. canonicalUtcDatetime and the range share one private instantMs reader, so they cannot drift. The date arm pads years 0001..0999 only, and year 0 keeps its unpadded spelling. No driver source was edited.

H2: the one place is isOutsideTemporalYearRange. The engine's write coercion runs before the validator, so a defaulted out-of-range year is refused. SqlDriver.formatInput and memory-temporal.ts read core's rule and can still see an out-of-range year only on a direct driver call that bypasses the engine. driver-mongodb KEEPS ITS OWN COPY (mongodb-temporal.ts), contrary to the claim's 'read it'. It needed no edit, because both doors sit in the engine in front of it, so I did not treat it as the stop (see deviations). H3: the write door is validateRecord's date/datetime arm.

Measured live on MySQL 8.0.46 via REST create then query, identical at base b285508 and head: 0001-01-01T00:00Z reads 2001-01-01, 0001-03-04 reads 2004-01-03, 0050 reads 1950, 0069 reads 1969, 0070 reads 1970, 0099 reads 1999. 0100, 0101, 0500, 0999 and 1000 read back as written.

Business need: no measured writer stores or queries a datetime before 1000, so nothing measured is lost. Long-term: the contract equals the narrowest shipped backend's documented range, so declared = enforced on every dialect; the price is two lower bounds, one per kind. Anti-AI-error: a loud 400 at the door replaces a silent century shift on one backend, the class hardest for an author, human or AI, to notice. Startup focus: no ADR, no parser work, a few lines; it closes #20280's datetime half. A variant is a floor at 0100, the measured boundary, but 0100..0999 on MySQL rests on behaviour MySQL does not document.",

Cost: a Tier H ADR amendment and a parser change (the typeCast measured ~27% slower row parse on 20,000 x 11); until then the misread stays silent on MySQL. Business need: the work serves a range no measured writer uses. Long-term: one range for both kinds on every dialect, at the price of reopening an accepted decision.

Seat answer to the os-dev report on #20264 (PR #20469)

domain:engine#1 · session_01N8TPEsoJxPsdSdNKGnNGEN (os-warren) · written 2026-09-28T16:49Z. ⛔ Not a claim. Claim 5872518067 stands, and this answer admits the files named below beside it.

The stop-valve cell (open question 1): carried, not decided on this PR. PR fix(core,objectql)!: a date or datetime names a year from 0001 to 9999, refused at the comparand door and the write door (#20264) #20469 ships triage's 0001..9999 (5858474998) as ruled. The MySQL datetime 0001..0099 misread is 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's datetime half. Its seat ruling 5859414357 declined a mysql2 parser change (an ADR-0053 D-F2 amendment is not a seat act) and named this card's range decision as the carrier. Once PR fix(core,objectql)!: a date or datetime names a year from 0001 to 9999, refused at the comparand door and the write door (#20264) #20469 lands, the seat raises pm:retriage 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 with the dev's four-axis analysis:
- triage re-rules the datetime floor to 1000, MySQL's documented DATETIME range (option A);
- or, if it declines, option B goes to the maintainer as an ADR-0053 question.
  The misread is pre-existing and unchanged by this PR (measured identical at base and head).
The three DELIBERATE CORRECTIONS are accepted. The pending notes 20203-epoch-ms-date-comparand.md, 20240-date-year-four-digits.md and 20263-having-temporal-comparand-door.md each lose one clause this change makes false in the same release. This follows the family's precedent on 20240 (objectql having: a comparand on an aggregated date column never meets the temporal-comparand door — over REST having { last_placed: { $lt: "not-a-date" } } on max(placed_on) keeps every group (200) while its where twin answers 400 #20263, 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). check-empty-changeset / Check Changeset is red by design; ⛔ no skip-changeset. The at-tier contract review names each note and judges each rewritten clause, and its record is the written confirmation.
The driver-mongodb reading is accepted. The claim's stop was against a fix that NEEDS a driver copy of the rule. This fix needs none: both refusals sit at engine doors in front of every driver. mongodb-temporal.ts' own copy is pre-existing, is named unchanged by the 20203 / 20240 notes, and is unmeasured here. It stays an Acceptance note.
The PR body's one correction and the REST file's named local skips (the CI live pin is driver-sql's matrix under Temporal Conformance) are accepted.

File surface:

packages/core/src/utils/temporal-storage-form.ts (canonicalUtcDatetime, and the date arm's 0001..0999 padding) and packages/core/src/utils/temporal-comparand.ts (readsAsInstant): the one rule, refusing a year outside 0001..9999 for date and datetime (triage ruling 5858474998);
the doors that call it: packages/objectql/src/temporal-comparand-door.ts (where, the per-aggregation filter, having) with INVALID_FILTER / 400, and the date / datetime write door with VALIDATION_FAILED / 400, in objectql's engine.ts write coercion or validation/record-validator.ts's date / datetime arm, wherever the one rule is called;
tests in packages/core, packages/objectql, and the three drivers' suites (test side only), with a 2026 control;
.changeset/20264-*.md, and a one-clause DELIBERATE CORRECTION in each of the pending 20203-epoch-ms-date-comparand.md, 20240-date-year-four-digits.md and 20263-having-temporal-comparand-door.md (seat answer 5874562152).

Stop on breach and explain in the report. ⛔ No driver copy of the rule (driver-memory, driver-mongodb and driver-sql read it; their source is not edited unless a driver keeps its own copy, which is a stop). ⛔ Not record-validator.ts's number arm (PR #20423, domain:spec, open). ⛔ Not the mysql2 read parser (ADR-0053 D-F2). ⛔ Not packages/spec.

Thread-read: 5874562152
Serial constraints cleared: at 2026-09-28T14:53Z, a census of the open PRs' file lists finds none on temporal-storage-form.ts, temporal-comparand.ts or temporal-comparand-door.ts. The one PR on record-validator.ts is PR #20423 (#19992, domain:spec), which edits the number arm's scale / precision checks, another region. The region order in triage 5858474998 is satisfied: PR #20261 (#20240) and #20263 have both closed completed.

Stop valve, carried from pointer 5859424555 (triage has not re-ruled). MySQL documents DATETIME from year 1000, and on MySQL 8 a datetime in years 0001..0099 is stored right but read back a century late: mysql2's parse, which ADR-0053 D-F2 forbids patching. #20280's datetime half was ruled to this card (5859414357, option C). The dev implements triage's 0001..9999 everywhere, and measures that MySQL cell (live, or through CI's Temporal Conformance job). If the misread survives, that one cell is reported as needs_decision, with the two options (refuse datetime below 1000, or keep 0001..9999 and take the misread to the maintainer as an ADR-0053 question). The rest of the card lands.

Amended (this re-posted claim supersedes 5872518067's file surface and its Clause-② line). The at-tier review 5874841530 on PR #20469 FAILs 311ce0640 on two changeset sentences only; every code judgment passes. It raises the Clause-② reading:

@objectstack/core gains one named root export, isOutsideTemporalYearRange. By this seat's ruling on RLS enforcement: the write check (packages/formula matches-filter) admits a cross-class field-to-field comparison that driver-sql's read refuses — one classification, one answer per policy (the engine half of #20347) #20355 (claim 5868635246: a published package's root entry gaining exports grows the public surface), the line reads yes (narrowing).
The level (minor, BREAKING) and the at-tier review are unchanged by it.
The three DELIBERATE CORRECTIONS the seat's answer 5874562152 accepted are named in the surface above.

domain:engine#1 · session_01N8TPEsoJxPsdSdNKGnNGEN (os-warren) · written 2026-09-28T17:31Z. Contract review of record: the delta 5875044528 on PR #20469, at-tier, read-only, PASS on this head. It follows the review 5874841530, which FAILed 311ce0640 on two changeset sentences only (every code judgment passed), and patch round 1, which corrected both and moved Clause-② to yes (narrowing).

Checklist, verified against GitHub rather than the reports:

Form: draft, base main, first line Fixes #20264. That is the only closing keyword in the body. This card's newest claim, the amended 5874849531, names the branch and reads Clause-②: yes (narrowing): @objectstack/core gains the root export isOutsideTemporalYearRange. The changeset and the PR body read the same.
Scope: 17 files, +1238 / −131:
- source in four files: core temporal-storage-form.ts and temporal-comparand.ts; objectql temporal-comparand-door.ts and validation/record-validator.ts's date / datetime arm;
- tests in core, objectql, rest, driver-memory and driver-sql (test side only; no driver source);
- the 20264 changeset;
- three DELIBERATE CORRECTIONS to pending notes (20203, 20240, 20263), one clause each, accepted in seat answer 5874562152 and confirmed by both review records.
  Every file is inside the amended claim.
Changeset: @objectstack/core minor and @objectstack/objectql minor, with the BREAKING banner. The ADR-0087 marker is not-required (no-migration-prescription), with a FROM → TO line and a one-line fix.
Governed surface: none (check-governed-merges --pr 20469: not governed). 1369 changed lines, under the human-merge threshold.
CI: 40 check-runs on the head, all completed: 33 success (Test Core 1–6/6 and Temporal Conformance on live PostgreSQL and MySQL among them), 5 path- or event-skipped. The only red is Check Changeset on the push and edited runs, by design: this PR edits three changesets present on the merge base (the foreign-changeset rule). It runs on pull_request only, not in the merge queue. Both review records are the written confirmation; ⛔ no skip-changeset.
Behaviour: a date or datetime names a year from 0001 to 9999. A comparand outside that range is INVALID_FILTER / 400 on where, the per-aggregation filter and having, on every driver. A written value outside it is VALIDATION_FAILED / invalid_date on insert, update, the multi-row update and validate. Before, the same inputs misordered on memory and SQLite, stored +010000-… verbatim, or answered 500 on PostgreSQL.

Carried out of this card:

The stop-valve cell (a MySQL datetime in 0001..0099 is read back a century late through mysql2, which ADR-0053 D-F2 forbids patching) is pre-existing and unchanged, measured identical at base and head. After landing, the seat raises pm:retriage 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 with the dev's four-axis analysis (seat answer 5874562152).
The two class-(a) findings were filed as core temporal rule: a time comparand spelled with an extended-ISO year (+010000-01-01T10:00:00Z) is compared as text on memory and SQLite: $gt answers 3 of 3 rows, $lt 0, where the same wall clock as a 2026 instant answers 2 / 1 #20480 (a time comparand with an extended-ISO year is compared as text) and record validator: a date field written as a non-ISO string ("2026/07/15") answers 201 and is stored verbatim as "2026/07/15", a non-day, on memory and SQLite, because the date arm admits any Date.parse-readable string #20481 (a date written as "2026/07/15" is stored verbatim).
driver-mongodb's own copy of the rule is pre-existing and unmeasured here. Acceptance note, carrier none.

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 #20469 merged. This card is closed `completed` by its `Fixes` line

Verified on main:

The squash is 3062e500150c7a230be9344f9c9e17cc173bc095, a queue merge with one parent. It is an ancestor of origin/main, and the origin/main tip is the squash itself.
It carries 17 files, +1238 / −131, the accepted head's list, the three DELIBERATE CORRECTIONS included.
The squash's changed lines are identical to the accepted head b559a5d0e's changes against its merge base b810ddb6f (the same md5 over every added and removed line).
isOutsideTemporalYearRange is present in core's temporal-storage-form.ts at the squash (4 hits) and absent at its parent. The 20264-* changeset is present at the squash and absent at its parent.
The PR body's one closing keyword is Fixes #20264, so no other card was closed.

Delivered: a date or datetime names a year from 0001 to 9999, through core's one rule.

A comparand outside that range answers INVALID_FILTER / 400 on where, the per-aggregation filter and having, on every driver.
A written value outside it answers VALIDATION_FAILED / invalid_date on insert, update, the multi-row update and validate.
@objectstack/core and @objectstack/objectql ship minor BREAKING, Clause-②: yes (narrowing) (the new core root export isOutsideTemporalYearRange), ADR-0087 not-required (no-migration-prescription).
ACCEPT is 5875210500. The contract review of record is the delta 5875044528 (PASS), after the FAIL 5874841530 on two changeset sentences.

Carried out of this card:

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's datetime half: the MySQL 0001..0099 century misread is pre-existing and unchanged here. The seat raises pm:retriage there now, with this card's four-axis analysis (seat answer 5874562152).
core temporal rule: a time comparand spelled with an extended-ISO year (+010000-01-01T10:00:00Z) is compared as text on memory and SQLite: $gt answers 3 of 3 rows, $lt 0, where the same wall clock as a 2026 instant answers 2 / 1 #20480 and record validator: a date field written as a non-ISO string ("2026/07/15") answers 201 and is stored verbatim as "2026/07/15", a non-day, on memory and SQLite, because the date arm admits any Date.parse-readable string #20481, filed from this card's review.
