feat(driver-sql): the read door presents datetime values and audit stamps as canonical ISO-Z text on every dialect (#13973, B1 narrow) - #16619

Fixes #13973

Clause-②: yes

What this lands — the B1 (narrow) ruling, verbatim from comment 5507803003

Ruled: B1, narrow form. For the builtin audit columns (created_at, updated_at) and every declared Field.datetime column, driver-sql's read door presents the canonical instant YYYY-MM-DDTHH:MM:SS.sssZ on every dialect, exactly as it already does on SQLite: the two if (this.isSqlite) gates around repairNaiveUtcAuditTimestamp and normalizeSqliteDatetimeOutput in formatOutput become unconditional (the latter already carries an instanceof Date arm), the aggregate() / distinct() presentation path (readPresentationKind) gains the same arm for the two column classes, and the #14078 NaN guard (ruled B) makes the conversion total. ⛔ The pg client type parser is not touched — Date stays the client-level materialisation; the driver canonicalises at its own read boundary.

Maintainer provenance on the card: 「同意」 (2026-09-02, director seat summon #8). Governed surface in the diff (docs/adr/**) ⇒ this PR stays draft and lands by a human's hand; the ordinary ready → auto-merge → queue path does not apply.

The change, by symbol (packages/drivers/driver-sql/src/sql-driver.ts)

The JSON, numeric and boolean read repairs keep their dialect gates exactly as they were. The pg and mysql2 client parsers are not touched — §C of the new conformance file proves a raw knex read still hands the driver a Date on both live cells while the read door hands out text for the same row.

One mechanism finding against the ruling's own text. The ruling says the two gates "become unconditional (the latter already carries an instanceof Date arm)". The former — repairNaiveUtcAuditTimestamp — is string-only by contract (if (typeof value !== 'string') return value;), so flipping its gate alone leaves Postgres' and MySQL's Date exactly where it was. The audit loop therefore gets a Date arm of the same spelling (presentAuditTimestampOutput); without it the ablation below stays red on the audit column.

The NaN-guard totality, re-derived at the driver's own boundary (PM Zone 2). The five ruled-B arms PR #16427 landed live in CONSUMERS (protocol.ts, sys-metadata-repository.ts ×2, rest-server.ts ×2, database-loader.ts ×2), not in the driver, so they do not make the driver's conversion total by themselves. What does is the driver's own Date arm: isoFromValidDate returns an Invalid Date unchanged (Number.isNaN(getTime())), the same spelling as isoFromValidDate in the ruled-B family, so the fold never throws — total in the sense #14078 ruled. The consequence is stated rather than hidden: for the one shape #14078 measured (a MySQL zero DATETIME; a Postgres year in 275760..294276) the read door still hands out the client's Invalid Date, and the ruled-B consumer arms absorb it. ADR-0053 D-F3 declares exactly that; sql-driver-14078-invalid-date-materialisation.test.ts §B2/§B3 keep pinning it on both live dialects. The alternatives (fold to null; fold to the text Invalid Date) are a decision the ruling did not make and are listed in the report's open_questions.

The driver comment's dependency claim — falsified on the tree. "Field.datetime depends on [the Date materialisation]": before this change formatOutput never touched a datetime column on Postgres/MySQL (the fold was SQLite-gated), so nothing on the read path consumed the Date; every in-repo reader of the value (the class (a) sites, the new Date(v) wrappers in this package's own live tests, the ruled-B arms) already accepts the text form; and the full driver-sql suite in CI's live shape is green with the fold unconditional (below). The comment is rewritten to say what was checked.

Interaction with PR #16579 (same file, earlier today): none. It touched formatDuplicateGroups (lines ~4213 and its three call sites in the hash-shadow duplicate render); this PR touches the read-presentation region 12 000 lines away. The merge of origin/main (7 commits since the branch point) was clean and none of them touched sql-driver.ts.

Patch round — the contract review's three findings (comment 5572260375, PASS WITH FINDINGS)

The B1-narrow ruling was found landed correctly and is not re-shaped here; the three findings below are what a maintainer would otherwise read wrong or inherit. Commit 536a172913, then origin/main merged (f9591b98b6).

FINDING-1 — the headline sentences stated an absolute invariant the same addendum carves two exceptions out of. Four sentences said, in effect, "a read door never hands out a JS Date for these columns" while D-F3 (an Invalid Date leaves as a Date) and D-F1's own "Not covered: findWithWindowFunctions" (#16609) say otherwise. Each headline now carries its own carve-outs, in the words the anchor invariant already used: the ADR-0053 status line ("every @objectstack/driver-sql record read door but findWithWindowFunctions (#16609) … those doors never hand out a JS Date for those columns, save an Invalid Date, which has no canonical text and passes through unchanged"); D-F1's opening ("every record read door … listed here") and its invariant sentence ("None of these doors hands out a JS Date for these columns, save the one shape D-F3 names … findWithWindowFunctions is not one of these doors"); and the conformance file's docblock (same two carve-outs, with where each is pinned). The contract is not weakened and the exceptions are not deleted; node scripts/check-adr-anchors.mjs and node scripts/check-adr-links.mjs both exit 0 after the edits.

FINDING-2 — "declared = enforced" was short by three doors. Option taken: add the cells (not narrow the sentence). §A5 upsert() (merged onto an existing row, and inserted), §A6 bulkUpdate(), §A7 bulkCreate(), on a second fixture table so their writes cannot move what §B1/§B3 compare against. §0's guard (defined, non-null) is carried inside expectCanonicalInstant, so a door returning a row without its audit columns fails rather than passing over nothing. upsert() and bulkUpdate() read the row back after their statement on every dialect, so the guard applies unqualified. bulkCreate() mirrors §A3's honesty: it asserts over the rows a dialect's bulk insert returns (all rows or none — a door that dropped part of a batch cannot pass as "no RETURNING"), and its always-non-vacuous leg reads the batch back through find() and holds the return equal to the row value for value where a row came back. Which columns a dialect returns is not pinned. D-F1's enforcement paragraph now says exactly this. Measured: 3 doors × 3 cells = 9 new cells, green on SQLite, live Postgres and live MySQL.

FINDING-3 — a reproducible find() vs aggregate()/distinct() divergence this PR introduced. Option taken: (1) one shared presenter, not (2) a gate on the declaration. Mechanism, on the tree: readPresentationKind's added audit arm answered 'datetime', so the two doors folded a number to ISO text where find()'s presentAuditTimestampOutput passes it through (ADR-0074 §3); option (2) would have left the second reachable shape — an epoch INTEGER raw-written into the undeclared audit column — divergent, because the undeclared column would still take the datetime fold at these doors and the audit presenter on find(). So: a new ReadPresentationKind member 'audit_timestamp', answered for created_at / updated_at after the temporal check (a declared temporal audit column takes the temporal kind, exactly as formatOutput's datetime fold runs after its audit fold), and presentReadValue routes it to presentAuditTimestampOutput — the function formatOutput itself calls. presentReadValue's docblock no longer claims "exactly the way formatOutput presents it"; it says what is true: one presenter per kind, the presenter formatOutput calls, and the one place a row walk's composition is not replicated (the SQLite numeric repair before the audit presenter on a declared-number audit column) — where the two differ on any TEXT that Number() accepts but SQLite's NUMERIC affinity leaves as TEXT (hex, binary and octal literals, and Infinity), reachable through create() / update() on the driver's own DDL with an author-declared non-temporal audit column; the delta review reproduced it ('0x10' → find() 16, distinct()/max() '0x10') after the first cut of that sentence had claimed the residue needed a hand-made TEXT-affinity column — corrected in 974731b1c6, behaviour untouched (the shape lies outside the B1 ruling's column classes; whether to close it is in the report's open_questions). Pinned as §D on the SQLite cell only: D1 the review's shape (created_at: number, 1700000000000), D2 a raw-written epoch INTEGER in both undeclared audit columns, D3 the control (a legacy zone-naive audit string still folds to ISO at these doors, so the number agreement was not bought by losing ADR-0074's repair). SQLite is the whole coverage and not a shortfall: the DDL never types the audit column from the declaration (builtinColumns skipped, createAuditTimestampColumn runs), so on Postgres it is a timestamptz and on MySQL a DATETIME(3) — neither can hold a number, and the write that would put one there is refused — SQLite's type affinity is what makes the shape reachable at all. Changeset unchanged: its sentence "now present exactly what find() presents" was the claim; the fix is what makes it true.

Ablation for FINDING-3 is under Evidence. Not touched, each for the review's stated reason: the seven out-of-package normalizeSqliteDatetimeOutput comments (a follow-up card, not a rider), #13993–#13999 and the five ruled-B arms, findWithWindowFunctions (#16609), the Invalid-Date fold options (a maintainer decision, left in open_questions). One consequence for a file the review called CORRECT, noted rather than acted on: the anchor JSON's invariant names "presentReadValue's datetime arm" — still true (that arm exists and runs on every dialect), now incomplete by one arm name; the optional one-line precision is in the report's open_questions.

Step one — the consumer census (re-runnable)

Consumers that call a Date method directly on a record field fail loudly under B1. Three expressions, each with a positive control, run from the repo root at b4abb0a91 and re-checked on the merged head:

E1 — named timestamp fields followed by a Date method (positive control: the bare \.toISOString\( count over the same globs is 733):

M='(getTime|toISOString|toJSON|valueOf|getFullYear|getMonth|getDate|getDay|getHours|getMinutes|getSeconds|getMilliseconds|getTimezoneOffset|getUTC[A-Za-z]+|setUTC[A-Za-z]+|setFullYear|setMonth|setDate|setHours|setMinutes|setSeconds|setMilliseconds|setTime|toLocaleDateString|toLocaleTimeString|toLocaleString|toDateString|toTimeString|toUTCString)'
FIELDS='(created_at|updated_at|createdAt|updatedAt|deleted_at|deletedAt|occurred_at|occurredAt|recorded_at|recordedAt|expires_at|expiresAt|started_at|startedAt|completed_at|completedAt|reverted_at|revertedAt|last_seen_at|lastSeenAt|authored_at|authoredAt|published_at|publishedAt|_at)'
rg -n --no-heading -g 'packages/**/*.ts' -g '!**/dist/**' -g '!**/node_modules/**' -g '!**/*.d.ts' \
   "(\.|\[['\"])${FIELDS}(['\"]\])?\??\.${M}\(" packages

7 hits, none a driver-row consumer that breaks: platform-objects/…/system-overview-tile-semantics.test.ts:220 (in-memory fixture objects), client/src/return-type-precision.test.ts:770 (the SDK's own DTO type, wire-fed), metadata-protocol/src/protocol-14078-…test.ts:9 (a comment), plugin-auth/src/scim-connection-service.ts:159 (input.expiresAt, a caller-supplied Date, not a read), metadata-protocol/src/protocol.ts:8654-8655 (guarded by instanceof Date — the ruled-B arm, now a no-op on driver rows), plugin-auth/src/session-tombstone.test.ts:427 (a Date the code WRITES, read off a mock's patch).

E2 — any receiver, any field, then a Date method, non-test source only (same M; new Date(, Date.now, Date.UTC, process. and this.clock/now receivers excluded): 6 hits — the scim-connection-service.ts:159 and protocol.ts:8654-8655 sites above, create-objectstack/src/created-summary.ts:221-222 (Number.prototype.toLocaleString), metadata/src/loaders/filesystem-loader.ts:336 (fs.Stats.mtime). None reads a driver row.

E3 — as Date / angle-bracket Date casts in non-test source: 0 hits; positive control: the same expression over *.test.ts in driver-sql hits the #13567 / #14078 pins (4 and 3 as Date sites on the pre-change tree).

E4 — the empirical census inside the only package that sees a live dialect: the whole driver-sql suite in CI's live shape (TZ=America/New_York, both live cells, OS_EXPECT_LIVE_DIALECT_MATRIX=1) — every pin that asserted the old Date side is listed under "repaired" below; nothing else went red.

Repaired in this PR: the three driver-sql pins that asserted the Date side (#13567 §B1–§B4, #14078 §B1, and the #11389 comment restating the falsified dependency). Filed: none needed — no non-test consumer calls a Date method on a driver-row field. The seven class (c) site cards (#13993–#13999) and the five ruled-B arms are untouched, per the ruling: under B1 their canonicalisations become no-ops, not conflicts.

Contract line

• ADR-0053 addendum D-F1..D-F3 (docs/adr/0053-date-and-datetime-semantics.md, status line + a new addendum): D-F1 the read door returns datetime values and the audit stamps as the canonical ISO-Z text on every dialect (declared = enforced, cells named); D-F2 folded at the driver's read boundary, client parsers untouched; D-F3 the Invalid Date residue passes through. ADR-0074 gets a one-line status pointer (its read repair is no longer SQLite-only in effect). The scripts/adr-anchors/…sql-driver.ts.json anchor gains ADR-0053 with the invariant in its failure text.
• Conformance cells — sql-driver-13973-canonical-iso-read-door.test.ts (new): per cell of the D-A3 driver axis, find/findOne/update-return/create-return (§A1–§A3), upsert/bulkUpdate/bulkCreate returns (§A5–§A7, patch round), aggregate (min/max over the declared datetime AND the audit columns, a raw temporal group key), distinct over all three, the Field.date control untouched, §C the raw-knex read proving the fold is the driver's, and §D (SQLite) the one-presenter agreement between find(), distinct() and aggregate() on the audit columns. sql-driver-13567-… §B re-pinned to the ruled shape on every cell (its §A, the record of why a Date at the door was a defect, is kept). sql-driver-14078-… §B1 control re-pinned to text; §B2/§B3 (the Invalid Date residue) unchanged.
• Changeset minor for @objectstack/driver-sql, naming the consumer-visible change (Postgres/MySQL in-process consumers receive text where they received a Date; the wire is unchanged).

Evidence

Everything below ran in the worktree on the branch; every exit code was captured after a redirect, never through a pipe, and every gate verdict quoted is the gate's own line. First round's union at c8fe535616; patch round's union at f9591b98b6 (the fix 536a172913 + the merge of 20 origin/main commits, none touching this PR's driver, test or ADR files); docblock correction at git rev-parse --short HEAD = 974731b1c6 (comment-only, 974731b1c6 on top of a clean merge of 3 more origin/main commits 48f1ad8a97; at that head the four touched files on all three live cells Test Files 4 passed (4), Tests 111 passed (111), driver-sql typecheck 0 errors, check-adr-anchors / check-adr-links exit 0, gate union re-derived and re-run: "Run reconciliation — 72 derived, 72 run, 0 NOT-MEASURED, 0 UNRUN."; no ablation, none is owed for a comment).

Patch round, on a fresh local Postgres 16.13 (timezone=Asia/Shanghai, :54331) and MySQL 8.0.46 (default-time-zone=+08:00, :33073), process TZ=America/New_York, OS_EXPECT_LIVE_DIALECT_MATRIX=1 — dependency closure rebuilt after the merge (pnpm --filter '@objectstack/driver-sql^...' build, lock VERDICT command-exit 0):

• Baseline before any patch-round edit, the four touched files on all three cells: Test Files 4 passed (4), Tests 99 passed (99).
• After the patch, same four files, all three cells, at f9591b98b6: Test Files 4 passed (4), Tests 111 passed (111) — +12 = the 9 door cells (3 doors × 3 cells) + §D1–§D3, lock VERDICT command-exit 0.
• Ablation for FINDING-3, committed fix first, both legs traced. Mutation = the one line the review named as the cause, readPresentationKind's audit arm answering 'datetime' again (anchor counts before: fixed 1 / mutant 0; after: fixed 0 / mutant 1; on-disk blob caec12253e… ≠ HEAD blob 027b83b077…). Predicted: red on §D1/§D2's distinct()/aggregate() legs and §D3's toContain(EPOCH) leg, green on every §A/§B/§C cell of every dialect. Observed, the conformance file on the full matrix: Tests 3 failed | 36 passed (39), exactly §D1, §D2, §D3, e.g. distinct(created_at) disagrees with find(): expected [ '2023-11-14T22:13:20.000Z', … ] to deeply equal [ 1700000000000, 1700000000001 ] — the reviewer's reproduction, verbatim direction. Restore by git checkout HEAD -- ABS_PATH: on-disk blob 027b83b077… = HEAD:…sql-driver.ts, git diff HEAD empty, git status --porcelain empty for the path, anchor counts back to fixed 1 / mutant 0; re-run Tests 39 passed (39). Stale build ruled out two ways, both printed by the script: this worktree never built driver-sql itself (no packages/drivers/driver-sql/dist exists), and the tests import ./index.js, which vitest resolves to src/index.ts (the pairing scripts/check-test-source-alias.mjs pins) — the mutated bytes are what ran.
• Typecheck at f9591b98b6: pnpm --filter @objectstack/driver-sql exec tsc --noEmit --listFiles — 0 errors, the conformance file in the program (1 --listFiles hit).
• Lint, narrowed with its three pieces of evidence at f9591b98b6: --print-config resolves for both touched source files (exit 0), --format json counts 2 files / 0 errors / 0 warnings, and eslint.config.mjs states no type-aware linting for any file (no parserOptions.project, no typed rule), so this diff cannot move an untouched file's verdict.
• Gates at f9591b98b6, derived from the merge-base changeset with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands (no hand-listed paths; 72 families), each exit code captured after a redirect, reconciled with --ran: "Run reconciliation — 72 derived, 72 run, 0 NOT-MEASURED, 0 UNRUN." 69 of 72 exit 0 (check:adr-anchors, check:adr-links, check:adr-symbol-anchors, check:query-options-erasure, check:test-source-alias, check:type-check-coverage, check:dts-closure, check:nul-bytes among them). NOT MEASURED, exit 3 each, in the gates' own words: check:type-check-debt ("check-type-check-coverage: PREREQUISITE NOT MET"), check:dual-build-cjs-loads ("PREREQUISITE NOT MET — this gate reads built output, and some package has no dist/"), check:doc-formula-expressions ("PREREQUISITE NOT MET — the workspace package @objectstack/lint is not built … Nothing was measured"). The cause is the unbuilt dependency closure, not memory (the seat measured check:type-check-debt at 8192 MB with the same exit 3); none was chased with a workspace build.

First round's evidence, at c8fe535616, kept as recorded:

Live cells, locally, on a real Postgres 16 and MySQL 8.0. The container carries the server binaries, so both were provisioned the way CI's job does (PG timezone=Asia/Shanghai on :54329, MySQL default-time-zone=+08:00 on :33071, process TZ=America/New_York, OS_EXPECT_LIVE_DIALECT_MATRIX=1 so a missing cell is red, not skipped); the testkit's three-way zone skew guard passed on both cells. Data dirs under /tmp/os13973-live, torn down after the run.

• Baseline before any edit (the OLD pins, updated_at instanceof Date on both live cells): Test Files 2 passed (2), Tests 29 passed (29).
• Full driver-sql suite in CI's shape at the fold unconditional: Test Files 167 passed (167), Tests 3623 passed | 1 skipped (3624), lock VERDICT command-exit 0 (the one skip is pre-existing and not in a touched file).
• The three conformance files at the final HEAD: Test Files 3 passed (3), Tests 60 passed (60).

Firing control (reverse verification), committed fix first, both legs traced. sql-driver.ts restored to its BASE blob (91337b2b…, hash-verified on disk; presentAuditTimestampOutput count 0, the old this.isSqlite ? … : value arm count 1), the three conformance files run on the live matrix: Tests 24 failed, every failure on the live postgres / live mysql cells — the new file's §A1–§A3, §B1–§B3 and §C, #13567's §B1–§B4, #14078's §B1 — and every SQLite cell green. Predicted direction was red on §A/§B and green on §C; §C reddened too, because its equality leg compares the raw Date's ISO text against the presented value, which under the old gate is itself a Date — reported as observed. Restore by git checkout HEAD -- ABS_PATH: on-disk blob 08d23fe4… = HEAD:…sql-driver.ts, git diff HEAD empty, git status --porcelain empty for the path; re-run Test Files 3 passed (3), Tests 60 passed (60). No build sits between the mutation and the run: driver-sql's tests import ./index.js, resolved by vitest to src/index.ts (the pairing scripts/check-test-source-alias.mjs pins), so the mutated bytes are what ran — stated, not skipped.

Typecheck. pnpm --filter @objectstack/driver-sql exec tsc --noEmit --listFiles: 0 errors at the final HEAD, and the new test file is present in the program (1 --listFiles hit; driver-sql's tsconfig has no test exclusion) — so the typecheck genuinely covers it. A first pass caught two Array.prototype.at uses (TS2550, lib target), fixed.

Lint. Full repo scan pnpm lint (eslint . --no-inline-config): exit 0. Also the narrowed form with its three pieces of evidence: population from eslint's own config (--print-config resolves for all 5 touched files, exit 0), --format json counts 5 files / 0 errors / 0 warnings, and type-aware linting is not enabled (eslint.config.mjs sets no parserOptions.project and no typed rule), so this diff cannot move any untouched file's verdict.

Gates. Derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after git fetch origin main and the merge (72 families; identical list before and after the merge). Each run with its exit code written to a TSV; union re-run at the final HEAD c8fe535616; reconciled with --ran: "72 derived, 72 run, 0 NOT-MEASURED, 0 UNRUN".

• 68 of 72: exit 0. Includes check:adr-anchors (with the new ADR-0053 invariant), check:adr-links, check:adr-symbol-anchors, check:query-options-erasure (a first pass grew the test surface 236 → 238 through two as any aggregate queries in the new file; they are on-contract and now carry the declared DriverQuery type — ratchet back to green, not widened), check:type-check-coverage, check:dts-closure (green after removing a half-built packages/lint/dist my own single-package build attempt had left; that artefact is not in the diff).
• NOT MEASURED, in the gates' own words, exit 3 each: check:type-check-debt ("PREREQUISITE NOT MET … measuring now would … silently measure a DIFFERENT WORLD"), check:dual-build-cjs-loads ("PREREQUISITE NOT MET — this gate reads built output, and some package has no dist/"), check:doc-formula-expressions ("PREREQUISITE NOT MET — @objectstack/lint is installed, but something it imports is not": @objectstack/sdui-parser unbuilt). All three need the whole-workspace build CI performs; per the PM's correction none was chased with a workspace build here.

Clause-②: yes — a published driver's read-door output shape changes on two dialects. needs:contract-review hung on the card and the PR together with this PR's opening.

维护者速读(草稿)

改了什么:@objectstack/driver-sql 的读门(find / findOne / create、update、upsert、bulkCreate、bulkUpdate 的返回行,以及 aggregate 的 min/max 与 distinct)在 Postgres 和 MySQL 上,对内建的 created_at / updated_at 和所有声明为 datetime 的字段,改为交出与 SQLite 一致的规范 ISO 文本(2026-09-07T12:00:00.123Z),不再交出 JS Date 对象。数据库客户端解析器一处未动;驱动在自己的读边界折叠。aggregate / distinct 对两个审计列走的是 find() 同一个呈现函数,三个门对同一列的答案逐值一致。ADR-0053 追加 D-F1..D-F3(状态行与 D-F1 的不变量句自带两个例外:无法折叠的 Invalid Date 原样交出;findWithWindowFunctions 不在覆盖面内,已立 #16609),ADR-0074 加一行指针,changeset minor。

为什么改:同一个「最后更新时间」在 SQLite 上是文本、在生产默认的 Postgres 上是 Date,44 个读库的包里 43 个只在文本侧测过,这个类已经出过 8 次事故(线上 1 次,普查读代码 7 次),方向全部是「期望文本、拿到 Date」,反向零次。这是您 2026-09-02 对 #13973 拍的 B1 收窄版(「同意」),本 PR 是落地。

风险与代价(含回滚):Postgres / MySQL 上的进程内消费者从此拿到字符串而不是 Date;直接对记录字段调 .getTime() 一类方法的代码会响亮报错——本 PR 的普查在非测试源码里一处都没找到;经 HTTP/JSON 的调用方看不到任何变化(JSON.stringify 本来就把 Date 序列化成同一段文本)。无法折叠的坏值(MySQL 零值日期、Postgres 超出 JS 范围的年份)原样交出 Invalid Date,与 #14078 的裁决一致。回滚:revert 本 PR 即可,无数据迁移、无存储变更;本地实测 Postgres 16 + MySQL 8.0 全绿(167 个文件 3623 个用例)。

席位意见:(留空)

你要做的:确认 ADR-0053 的 D-F1..D-F3 与您的裁决一致(状态行与 D-F1 现在是完整的一句话,不必翻到 D-F3 才知道它有例外),然后人工合并(受管面,不走队列)。若您希望坏值改交 null 或文本 Invalid Date,报告的 open_questions 列了两个选项,可另行裁定。

验收备注

• Noted, not filed: the seven per-site canonicalisations (service-queue: the publish idempotency window never expires on Postgres/MySQL — String(row.created_at) >= windowStart compares a Date.toString() against ISO text #13993–os migrate duplicates reports each holder's createdAt as a Date.toString() spelling on Postgres/MySQL #13999) and the five ruled-B arms (The shared canonical-ISO normaliser turns an Invalid Date from a driver into a 500, where String() served text #14078) are now no-ops on driver rows; their docblocks still describe the pre-B1 gate. Retiring or refreshing them is separate, deliberate work — the ruling says do not touch them here.
• Noted, not filed: seven out-of-package comments name normalizeSqliteDatetimeOutput while describing the old SQLite-only gate (sys-metadata-repository.ts, rest-server.ts, database-loader.ts and their tests); the function keeps its name (the ruling names it), its docblock now says it runs on every dialect.
• Filed as driver-sql: findWithWindowFunctions returns storage forms — a declared boolean answers 1 and an object field answers JSON text where find() answers true and the parsed object #16609: findWithWindowFunctions applies no read presentation at all (a declared boolean answers 1, an object answers JSON text on SQLite — reproduced from the built package). Out of the ruling's surface; ADR-0053 D-F names it as not covered. driver-sql: findWithWindowFunctions returns storage forms — a declared boolean answers 1 and an object field answers JSON text where find() answers true and the parsed object #16609 is not addressed here.
• The local live servers were provisioned under /tmp/os13973-live (first round) and /tmp/os13973-r2-live (patch round) — the scratchpad's ancestors are root-only and the postgres/mysql service users cannot traverse them — and are torn down with the worktree.
• Patch round, noted, not filed: the seven out-of-package normalizeSqliteDatetimeOutput comments want a follow-up card (the reviewer's point that "noted, not filed" leaves nothing queryable is taken); the card is the PM's to file, not a rider here.
• Patch round, noted, not filed: presentReadValue does not replicate formatOutput's composition of the SQLite numeric repair before the audit presenter on an author-declared number audit column — the two differ on any TEXT that Number() accepts but SQLite's NUMERIC affinity leaves as TEXT ('0x10', '0b101', '0o17', 'Infinity'), reachable through create() / update() on the driver's own DDL (delta review's reproduction). Recorded in the docblock; behaviour deliberately not changed — the shape is outside the B1 ruling's column classes and closing it is a decision the ruling did not make.
