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
Description
Filing gate: ① a product defect with a named landing site and a reach:. Finding class (a). reach: is a public door: REST POST /api/v1/data/:object, measured on memory and SQLite by the #20264 dev at PR #20469's head 311ce0640.
Filed by the domain:engine execution seat 1 (session_01N8TPEsoJxPsdSdNKGnNGEN, os-warren) from the #20264 dev's out_of_scope_findings[1] (os-dev-report on #20264, PR #20469). The readings are the dev's. ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim.
What happens
A date field written as "2026/07/15" answers 201 and reads back "2026/07/15". That is not the YYYY-MM-DD day the field's storage form promises, and it sorts and compares as text beside real days.
Where
packages/objectql/src/validation/record-validator.ts, thedate/datetimearm, admits anyDate.parse-readable string.packages/core/src/utils/temporal-storage-form.ts,temporalStorageForm(value, 'date'), keeps a string with no leadingYYYY-MM-DDunchanged.
It is the same mechanism as #20264's position 3 (an extended-year date stored verbatim), inside the year range, where #20264's ruling does not reach.
Suggested shape (⛔ not a ruling)
The date write door stores a day or refuses. Either it canonicalises any unambiguous calendar spelling to YYYY-MM-DD, or it refuses a string that is not ISO with VALIDATION_FAILED / 400 (invalid_date). Which one is triage's call: the spec's date storage form and the accepted input spellings. Pin through REST on memory, SQLite and PostgreSQL.

"summary": "Draft PR #20524 (Fixes #20481) makes the date write door store a day or refuse. The record validator's date arm now accepts a date STRING only when it carries a leading YYYY-MM-DD. That is the date storage rule's own reading, which temporalStorageForm collapses to that day. Every other spelling is refused with VALIDATION_FAILED / 400 (invalid_date) before any driver write, and nothing is canonicalised (triage 5875651303). The predicate is core's existing export isUninterpretableTemporalComparand('date', value), the same one the temporal-comparand door already refuses these strings with. So the two doors agree by construction, core is not edited, no export is added, and Clause-② stays no (narrowing) with an objectql-only changeset. Date.parse readability and the 0001..9999 range still apply on top. H1 holds: at base 0bbe400, REST create of '2026/07/15' answered 201 and read back verbatim on memory and SQLite. PostgreSQL 16.13 stored the day its DateStyle read ('07/08/2026' was 2026-07-08 under ISO, MDY; psql reads 2026-08-07 under DMY), and '+002026-07-15' was a 500. Head answers 400 invalid_date on all three. H2: '2026/07/15', '07/15/2026', '15 July 2026' and '2026-7-15' passed before and are refused now. '20260715' was already refused (no Date.parse reading). '2026-07-15T10:00:00Z', '2026-07-15 10:00' and ' 2026-07-15' are accepted and stored as '2026-07-15' before and after. H3: no shipped producer generates a non-ISO date string on the shipped composition (census in the PR body). The one raw-text path is objectui's legacy per-row import fallback, which runs only without /import; see open question 1. H4: the datetime arm stores nothing verbatim, but has a related host-zone defect, reported and not edited. H5 holds: a Date is still stored as its UTC day, and an epoch number is still refused with invalid_date; both are pinned.",

"question": "Triage says a shipped import format that sends a non-ISO date makes this needs_decision. objectui's Import Wizard has a legacy per-row fallback (plugin-grid/src/ImportWizard.tsx legacyImport → validateRow :561) that sends raw CSV/XLSX cell text for a date column, checked only by Date.parse (validateValue :486). After this lands, a '2026/07/15' cell on that path gets a per-row 400 invalid_date instead of being stored verbatim as a non-day, and the wizard's own pre-check still marks the cell valid. The fallback runs only when the data source has no importRecords or the client has no data.import (isUnsupportedImport :626). objectui's data-objectstack adapter implements importRecords (src/index.ts:4430), so the shipped console never takes this path; the server /import route turns every date cell into YYYY-MM-DD (import-coerce.ts parseDateCell). Does this path count as the triage's 'import format'?",
"options": [
"A — It does not: the import format is /import, which already emits YYYY-MM-DD. Land #20524 as is, and the seat files an objectui card so the legacy fallback refuses a date column up front, as it already refuses relation columns, or sends the server's coerced value.",
"B — It does: hold #20524 as needs_decision until the maintainer rules on the legacy fallback's date cells."
],
"recommendation": "A, on the four axes. Business need: measured, the shipped composition never reaches the fallback, and on /import (the real CSV path) nothing changes. Long-term soundness: the fallback already stores raw text, which is the defect this card closes; the fix belongs at that producer (triage: 'fixed at the producer'), not in a wider write door. AI-proofing: on that path the change turns a silent non-day into a loud per-row refusal naming ISO-8601, which is the NORTH-STAR rule 4 answer triage cites. Startup focus: holding a p2 integrity fix for a compatibility path no shipped build takes buys nothing."
