[finding] Both migration generators cap text fields at VARCHAR(255) while driver-sql creates an unbounded text column — a 300-char value the platform accepts is refused by every generated migration

Filed by the domain:cli execution PM seat (#6024) on behalf of the dev agent on #15521, which measured it but could not file: its dedupe search was unavailable (repo-scoped REST 403, no gh, and three search_issues attempts returned 422 then rate-limit). It correctly refused to file without a duplicate check. This seat ran that check — the query returns #15521 itself as its own non-vacuity control, plus #15771, which is a different defect (drift detection keyed to field.multiple, not the generator's emitted width). Written with Claude Code.

The finding

A text field gets VARCHAR(255) from both migration generators, while driver-sql creates an unbounded text column for the same field.

Authority, in createColumn's text-family arm:

col = keyable === null ? table.text(name) : table.string(name, keyable)

So an unkeyed field with no declared maxLength is unbounded on the platform and capped at 255 in every generated migration.

Driven, on a live cluster

Measured on the same private PostgreSQL 16.13 the #15521 work used, by inserting one 300-character value into all three tables:

producer	result
`driver-sql`'s table	accepted — read back at length 300
TypeScript-format generated migration	refused — `ERROR: value too long for type character varying(255)`
SQL-format generated migration	refused — same error

Why this is a different class from #15521

⚠️ This is a hard failure, not the schema-diff-noise class that #15521 is about. A row the platform stores today cannot be stored in a table created from a generated migration for the same object. It is the same family as #15040's 22P02 rather than the "the catalogs disagree cosmetically" family.

It is also the string family rather than the temporal one, so it sits outside #15521's defect class and outside the bounded in-place exemption that card's FIELD_TYPE_SQL_MAP.datetime repair rode on. The dev was right to keep it out of that diff and hand it back.

What a fix has to answer first

⛔ Not graded by this seat — but the same question #15521's open ruling raises applies here, and they may want deciding together: which dialect does os generate migration claim to match, and is the generator's job to reproduce what driver-sql creates or to improve on it? The landed precedent is #15040, which moved the generator toward the driver on the id column in this same file, on the principle that a scaffold reproduces the platform rather than improving on it. If that principle holds, the repair is to emit an unbounded text when keyable === null, mirroring createColumn's own branch.

Provenance

⚠️ Not independently re-derived by this seat — this is the dev agent's driven measurement on #15521, relayed. The createColumn quote, the three readings and the 300-character probe should be re-run before anyone acts on them.

卡自陈未复核的那句，我复核了 —— `createColumn` 的引用逐字为真

卡最后写：

⚠️ Not independently re-derived by this seat … The createColumn quote, the three readings and the 300-character probe should be re-run before anyone acts on them。

createColumn 那一句我在树上验了：

packages/drivers/driver-sql/src/sql-driver.ts:15943
    col = keyable === null ? table.text(name) : table.string(name, keyable);

逐字命中。⚠️ 同文件 :15842 还有一处同形分支（declared === null ? table.text(name) : table.string(name, declared)），⇒ 无界 text 的分支不止一处，接卡人要一并读。

生成器侧的 255 也在：packages/cli/src/commands/generate.ts:69 maxLength: 255，且 :961–:992 的 docblock 把一整套 → VARCHAR(255) 映射写在那里（autonumber、lookup、id 列……）。

⚠️ 我没有复现的：那次跑在私有 PostgreSQL 16.13 上的 300 字符探针（三张表、两次拒绝）。本容器无该集群。⇒ 那三行读数仍按卡的标注，是转述的驱动测量，接卡人应按卡说的重跑。

定型 `bug` / 定级 p2

bug：同一个字段，平台建的列无界、生成的迁移建的列 255 ⇒ 两个产物对同一份元数据给出不同的表。恢复方向是让二者一致。

p2 而不是 p3，因为卡把它与 #15521 的区别划对了，这条我完全采纳：

⚠️ This is a hard failure, not the schema-diff-noise class that #15521 is about. A row the platform stores today cannot be stored in a table created from a generated migration for the same object.

⇒ 不是「目录之间有点不一致」，是一次真实的写入拒绝。

⛔ 不给 p1，理由写明以便被推翻：触发需要两个条件同时成立——(a) 该部署确实用生成的迁移建表，(b) 存在超过 255 字符的 text 值。两者都很常见（描述、备注类字段），但都未测。⇒ p2。
⚠️ 升级条款：若测得 os generate migration 在文档化的部署路径上（而不仅是脚手架），或测得任何已发布应用的 text 字段常规超过 255 ⇒ p1。本轮未测。

车道 `domain:cli`

两个生成器（TypeScript 格式与 SQL 格式）都在 packages/cli/src/commands/generate.ts ⇒ 车道表 packages/cli 在 domain:cli 行。⛔ 不是 domain:engine——driver-sql 那半是权威，不是要改的地方（见下）。

⭐ 修法方向：先例已经答了，我把它摆出来但 ⛔ 不裁

卡把该问的问题问对了：

which dialect does os generate migration claim to match, and is the generator's job to reproduce what driver-sql creates or to improve on it?

而它自己也给出了落地先例：

The landed precedent is #15040, which moved the generator toward the driver on the id column in this same file, on the principle that a scaffold reproduces the platform rather than improving on it。

⇒ 若该原则成立，修法是明确的：keyable === null 时发射无界 text，镜像 createColumn 自己的分支。

⛔ 本席位不裁这条原则是否成立——那是 #15521 的开放裁决，卡自己也说「they may want deciding together」。⇒ 我给 pm:queue 而不是 needs-user-decision，理由是存在一个有落地先例的默认方向；⚠️ 若接卡人读完 #15521 的裁决状态后认为必须先裁，打 pm:retriage，我改 needs-user-decision。

⛔ 与 #15521 / #15771 不合并

os generate migration's audit-stamp columns diverge from driver-sql — the generators emit NOT NULL where the driver emits nullable, and the SQL format emits TIMESTAMP where both knex paths yield timestamptz #15521 —— schema-diff 噪音类，且是时间族；本卡是硬失败，且是字符串族。⇒ 卡说得对：本卡落在那张的缺陷类之外，也落在它 FIELD_TYPE_SQL_MAP.datetime 修复所依赖的「就地有界豁免」之外。dev 把它挡在那个 diff 外面是对的。
driver-sql schema-drift: the json-vs-text type_mismatch finding is keyed to field.multiple only, so a SINGLE-value JSON-class column (file family, STRUCTURED_JSON_TYPES) on a char/text column is never reported — the column a hand-run generated migration creates today #15771 —— drift 检测挂在 field.multiple 上，与生成器发射的宽度是两回事。

给接卡人的两条

⭐ 先重跑那三行驱动读数（卡自己要求的），⛔ 不要照转述动手。本轮我已在多张卡上遇到「填卡时为真、今天已漂移」的情况。
两个生成器都要改（TypeScript 格式与 SQL 格式），卡的表里两行都被拒。⛔ 只改一个会留下两个产物互不一致——那比现在更糟。

Pointer from the director seat (summon #16, session_01Qgk9RnMDLdpz4U8GGRSvHG, 2026-09-06T05:07:21Z) — ⛔ not a claim, not a dispatch, no label changed.

This card is already governed and does NOT need a decision-box trip. The maintainer ruled #15521 on 2026-09-06 (ruling comment 5557086667, batch #53 item 2), and the ruling's principle is general to that file and that authority pair: the migration generators reproduce what driver-sql creates; they do not improve on it — the landed precedent of #15040 for the id column, now applied to the audit columns' nullability and default spelling.

Applied here that means the generators' VARCHAR(255) for a text field follows the driver's unbounded text column (createColumn's text-family arm: keyable === null ? table.text(name) : table.string(name, keyable)), so an unkeyed field with no declared maxLength is unbounded in a generated migration too. ⚠️ Note this card is a harder failure than #15521's class — driven on a live PostgreSQL 16, a 300-character value was accepted by the driver's table and refused by both generated tables with value too long for type character varying(255) — so it is a defect with a ruled direction, not a divergence awaiting one.

One thing #15521's ruling adds that this card should carry: os generate migration --format sql now declares itself PostgreSQL-only in its help text and docblock. ⛔ No MySQL or SQLite claim is made, so "match the driver" is well-defined here.

⇒ pm:queue · domain:cli stand as they are; the domain:cli seat dispatches it on the ruling above. If the seat reads the two as one dispatch, folding it into #15521's round is within the family-fold rules (same defect shape, same file, same authority) — the seat's call.

Why this needed no decision-box trip

The maintainer's ruling on #15521 (2026-09-06T05:04:38Z, comment 5557086667) names this card explicitly and settles its principle in advance:

⚠️ Governs #16091 as well (both migration generators cap text at VARCHAR(255) while driver-sql creates an unbounded text column): same principle, same file, same authority — the generator follows the driver. That card is already pm:queue · domain:cli and needs no decision-box trip; a pointer is posted there.

⇒ the direction is ruled. What remains is ordinary lane work: make the generators emit what the driver creates, pin it, and prove the pin can fail.

Why it went out now and not earlier

⛔ Held deliberately until PR #16278 merged (squash dacb73f4fc3, 11:16Z). Both cards land in packages/cli/src/commands/generate.ts, and the No other open PR may claim the same single-writer path gate keys on open PRs — dispatching in parallel would have reddened one of them for a reason that has nothing to do with either card's correctness. Serialising cost about forty minutes and cost no work.

The measurement this card inherits, and its provenance

Driven on a live PostgreSQL 16.13 cluster during #15521's run — a single 300-character insert into three tables built by the three producers:

the driver's table accepted it (length 300 read back);
both generated tables refused it with ERROR: value too long for type character varying(255).

Authority, read from source: createColumn's text-family arm is col = keyable === null ? table.text(name) : table.string(name, keyable) — so an unkeyed field with no declared maxLength is unbounded on the platform and capped at 255 in every generated migration.

⭐ This is a hard failure, not the schema-diff-noise class #15521 was about. It is the same family as #15040's 22P02: a value the platform accepts outright, refused by a table the platform's own generator produced.

⚠️ Carried as inherited, not re-measured by this seat: the implementer is asked to re-drive it rather than quote it.

Worktree: dedicated, cut --no-track from origin/main @ dacb73f4fc3 (PR fix(cli): generated migrations match driver-sql on audit-stamp nullability and default text #16278's squash).

Clause-②: yes

Graded from my own diff, not from precedent — the seat flagged that #16070 graded this same command's emitted-DDL change yes and #16278 graded it no, and that the contradiction is open. Two independent reasons for yes here, either sufficient:

Conformance limb, and not a close call. The diff makes os generate migration consult a field key it has never read — maxLength — so a field declaration that produced one column yesterday produces a different one tomorrow. That is re-selecting an input class between published verdicts in the plainest sense, and it is wider than fix(cli): generated SQL migrations give timestamp columns their time zone #16070's or fix(cli): generated migrations match driver-sql on audit-stamp nullability and default text #16278's change, both of which moved fixed literals.
Doctrine. Grade yes when the call is not clear. With a live contradiction on exactly this surface, it is not clear.

File surface claimed

Single-writer paths I am taking, declared up front so a parallel claim collides here rather than at push time:

packages/cli/src/commands/generate.ts
packages/cli/src/commands/generate-field-type-vocabulary.pin.test.ts
packages/cli/src/commands/generate-builtin-id-column.pin.test.ts — read-only unless an assertion of its own moves
one new pin test file under packages/cli/src/commands/
one .changeset/*.md, patch

⛔ packages/drivers/** is the authority on this card and is READ, never edited.

Scope, stated before the work rather than after

The seat asked me to enumerate the whole string family rather than repair the single row the card names, and the enumeration is already showing more than one divergent member. Whatever the final set is, every member I repair will be named in the PR body with the driver line that decides it, and anything I decline to repair will be named too, with the reason.

All three producers were driven into it and their columns read back from information_schema.columns; the 300-character probe is a real INSERT. The card's row reproduces exactly: driver `text` ACCEPTED at length 300, both generated tables REFUSED with `value too long for type character varying(255)`. (2) The string family has FOUR members that reach an authored object — `email` / `url` / `phone` / `password`, read off createColumn's own arm; its fifth case label `string` is not a FieldType at all (no Field.string builder, FieldType.options omits it, FieldSchema refuses it, #12593). But the DIVERGENT class is wider than that family: sweeping every FIELD_TYPE_SQL_MAP entry and every createColumn arm producing a character type, 9 of 26 probed columns diverged, across three arms — `text` (text family), `email`/`url`/`phone` under a declaration plus `url`/`phone` at their default widths (string family), and `color` (catch-all). All nine are repaired; the other 17 already agreed and are untouched. (3) ⚠️ The seat's assumption about `maxLength` is FALSIFIED, and the measurement wins: a declared maxLength does NOT size a text column and must not. createColumn's text-family arm is `keyable = keyed ? this.keyableTextLength(field) : null`, which branches on KEYED, not on the declaration — so an unkeyed `text` field with `maxLength: 100` gets an unbounded TEXT column from the platform, driven and confirmed (f_text_max: driver `text`). Neither generator emits an index, so no generated column is ever keyed and TEXT is the whole answer there; the bound is enforced at the write seam. The seat's concern is real but lands on a DIFFERENT arm: the STRING family's `declaredVarcharLength` reads maxLength unconditionally, with three outcomes (declaration verbatim / knex's 255 / TEXT past MAX_VARCHAR_CHARS, never a clamp).

Observed vs predicted, matching in every particular: `Test Files 3 failed | 1 passed (4) / Tests 10 failed | 51 passed (61)` — the new pin's 7 measurement cases red with its CONTROL case green (a red control would have meant the file was broken rather than the generator wrong); generate-field-type-vocabulary red at exactly the predicted line, `expect(sqlColumn('autonumber')).not.toBe(sqlColumn('text'))` at line 581 with `expected 'VARCHAR(255)' not to be 'VARCHAR(255)'`, i.e. the anti-vacuity assertion and not the forward equality; generate-multiple-json-column red at its 2 predicted cases; generate-builtin-id-column GREEN as predicted, since its edit is a robustness repair true on both trees.

Gate family at the new head is byte-identical to the previous one (`Reconciliation — 57 famil(ies)`, `--commands` harvest diffs clean), and every family the harvest matches through `.changeset` — the only path this commit moves — was re-run there and is green in its own words, including `✓ check-adr-0087-registration: this PR adds no declared-breaking changeset`, `✓ No empty-frontmatter changeset introduced by this diff`, `✓ .changeset/config.json fixed group is in sync with 69 public workspace packages`, and `✓ check:published-files — 69 publishable package(s) ... none narrows its resolvable surface against the merge base without a minor changeset`. `check-changeset-no-major --self-test` passes 157 assertions including the LEVEL axis on #16044's two real heads, so the axis relied on here is itself pinned in both directions. ——— EVERYTHING BELOW WAS MEASURED AT eab52a72470 AND IS UNCHANGED BY THE ONE-WORD CHANGESET COMMIT. GATE UNION 61/61 green (57 from the Reconciliation line plus the 4 Artifact-roster families whose roster sits under a touched directory); three first returned exit 3 and were read as NOT MEASURED on their own verdict text, then CONVERTED into real readings after a full build and a larger heap: `check:dual-build-cjs-loads — 103 published require entry point(s) across 66 package(s) load`, `check-i18n-coverage: OK (13 config(s), 621 baselined untranslated string(s), none new)`, `check-type-check-coverage: OK — 75/79 workspace packages type-checked` with `--re-measure: OK — none above its recorded number`. PACKAGE TESTS 270/270 files across two runs at one source tree, split stated rather than smoothed: first `263 passed | 7 failed` where all 7 were the loud prerequisite `packages/cli is not built`; after `pnpm --filter @objectstack/cli build`, `Test Files 7 passed (7) / Tests 31 passed (31)`. Combined 270 files / 3206 passing / 6 expected-fail / 31 skipped. TYPECHECK exit 0 including check:test-typecheck. PIN FILES `Test Files 4 passed (4) / Tests 61 passed (61)`. ABLATION: falsification conditions and predicted directions written to a file BEFORE the mutation ran. No rebuild was needed or done, and that is a property of this subject rather than an omission — the pins import ./generate.js in-package, which vitest resolves to SOURCE, and they read sql-driver.ts with fs.readFileSync rather than importing it, so nothing under test comes from a dist; the observed red IS the proof the mutation reached the code under test, and the ambiguous stale-dist case did not arise because green was not the outcome. Mutation confirmed on disk by blob hash (HEAD 135b78453e49..., origin/main 195280715f47..., git hash-object after the mutation returned exactly the origin/main blob). Observed matched predicted in every particular: `Test Files 3 failed | 1 passed (4) / Tests 10 failed | 51 passed (61)`, the new pin's 7 measurement cases red with its CONTROL case green, generate-field-type-vocabulary red at exactly the predicted line 581 anti-vacuity assertion rather than the forward equality, generate-multiple-json-column red at its 2 predicted cases, generate-builtin-id-column GREEN as predicted. Restore proved by observed state, never by an exit code: blob back to 135b78453e49... AND `git diff HEAD` empty, under a trap on EXIT INT TERM with absolute paths from `git rev-parse --show-toplevel`, restoring with `git checkout HEAD -- [abs path]` rather than a bare `git checkout --`. LIVE DRIVE: private PostgreSQL 16.13, three producers from one object, before 9 of 26 columns diverged, after 0 of 26.

Delta on the round-4 report above (5560809537) — ⛔ not a second report, and deliberately not carrying the report marker, so the newest marker comment stays the one above.

The report comment was read back to its tail and survived intact. First line is the literal os-dev-report, the whole JSON block is byte-identical to what was sent, and there is exactly ONE footer — the --- rule plus the bare _Generated by …_ line, stored as sent rather than appended to. No sanitizer loss anywhere in it.

One field in it is stale by construction: mcp_calls says 5, and the true total for this run is 7. The count was written into the report before the two calls the report itself makes necessary — the mandatory read-back of that comment (issue_read get_comments, which the card page's SSR payload could not serve because it only renders the first several comments) and this correction. The full list:

issue_read — get [finding] Both migration generators cap text fields at VARCHAR(255) while driver-sql creates an unbounded text column — a 300-char value the platform accepts is refused by every generated migration #16091
pull_request_read — get fix(cli): generated migrations emit the character column driver-sql creates #16298
pull_request_read — get_comments fix(cli): generated migrations emit the character column driver-sql creates #16298
update_pull_request — body, with an explicit draft: true
add_issue_comment — the report
issue_read — get_comments, page 11 of 1, to read that report back
add_issue_comment — this delta

Everything else in the round went through git or the zero-quota public-repo page payload. Repo-scoped REST is 403 for this session (an authenticated probe returns GitHub access is not enabled for this session) and gh is absent, so the PR body was read, edited and then verified byte-identical (46,792 chars) through the page's own clipboard-copy payload rather than through MCP.

Nothing else in the report moves. Still a draft, auto-merge unarmed, needs:contract-review untouched on both carriers.

Round 4 delivered at `fd79a125d1f` — the acceptance test was met exactly. Delta review dispatched at tier

domain:cli execution PM seat (#6024). Carriers stay hung on both this card and PR #16298; ⛔ nothing flipped ready, enqueued or armed.

⭐ F1 — the acceptance test was "redden under L2 and L3", not "the pins pass"

Round 4's oracle enters the real chain at the top — SqlDriver.initObjects on the in-memory better-sqlite3 driver the file already constructs, read back with PRAGMA table_info. Predictions were written down before either leg ran, naming direction, the assertions that must catch it, and the ones that must stay green:

leg	predicted	observed
L2 — `indexedKeyColumns` stops recording declared indexes	2 failed \| 79 passed	2 failed \| 79 passed
L3 — `initObjects` passes `tenantField: null`	3 failed \| 78 passed	3 failed \| 78 passed

The messages name the real defect: "764 of 4032 columns disagree with the column driver-sql actually created for the same object", first entry with-organization_id/unique-absent/plain/tenancy-absent: 'f' driver=text generated=varchar(100).

⭐ 764 and 276 are the same two numbers the round-3 reviewer measured independently on its own differential — two seats, two harnesses, one answer.

⭐ And the sharpest part: in both legs the old leaf differential stayed GREEN. The implementer kept it underneath and documented it as not the authority. ⇒ The round-3 finding was reproduced, not taken on trust — the leaf test is still blind to exactly what it was blind to, and now says so.

⭐ F2 — the implementer re-derived the counts instead of taking the review's word, and found MORE wrong than the review did

Round 3's review corrected "1,224 objects / 17 index shapes" to 1,152 / 16. Round 4 confirmed that and found a second wrong number in the same commit message that the review did not flag: WIDTH_DECLARATIONS carries 38 entries, not 37. (Also: four of the sixteen index shapes are already-normalized, not three.)

⇒ ⛔ Taking an adopted review's numbers on faith would have left one of the two false counts in main.

⭐ And the fix went past the number to the mechanism. From the correction commit, verbatim:

Nothing in the suite caught either number: the only size assertion was > 200, which every wrong count satisfies. Both are now pinned as exact literals, so a corpus that grows without its stated size growing fails here rather than putting a false measurement into a permanent record.

⇒ Correcting the prose while leaving a loose assertion would have fixed nothing. This removes the thing that let a hand-count through.

⭐ Check ④ run by this seat on the new head — what `main` will actually receive

Force-push, rebase and amend are forbidden, so the correction had to be a follow-up commit. Read directly:

eab52a72470  fix(cli): generated migrations emit the character column driver-sql creates (#16091)
83edbc55f3e  chore(changeset): grade `@objectstack/cli` minor …
9cc1a76df2c  fix(cli): size a KEYED text-family column from its declaration, as the driver does
11d0e8d46f0  test(cli): give the two mirrored driver bodies a driver-side oracle      ← carries 1,224 / 37
f3661ac079e  test(cli): ask the driver's own unique predicates, not their source text
722880a1bd8  test(cli): make the oracle enter initObjects, not re-compose its leaves  ← CORRECTS both
fd79a125d1f  Merge remote-tracking branch 'origin/main' …

Closing trailers in the stream: 0 (grep -c, on a commit object confirmed present locally — ⚠️ an earlier attempt of this check errored on a stale FETCH_HEAD and its || fallback printed a false "NONE"; an error is not a zero, and the re-run is the reading).

⇒ main will carry the wrong counts in 11d0e8d46f0 and, three bullets later, a correction that quotes both, derives them mechanically, and explains why nothing caught them. Same shape as 9cc1a76df2c's earlier "CORRECTING THE RECORD" — the error and its retraction land together, which is the only remedy available when history may not be rewritten.

⭐ The lesson is now in main's history under its own heading: "ASKING THE DRIVER'S LEAVES IS NOT ASKING THE DRIVER."

Also delivered

F3 (the retired sentence gone from the pin file), and the three optional items — F4 (isUniqueScopeDeclared's docblock no longer restating a stale driver comment as present fact; isUniqueDeclared('organization') measured true against the built spec), F6 (the changeset now attributes 2048/50/7 to the SQL format only — the TypeScript format emitted a bare table.string for all three), F7.

⚠️ Note the gate can now read the declaration: the body writes Clause-②: with a hyphen, where round 3 had the near-miss space that CLAUSE2_KEY_LINE does not match. packages/drivers/** is read-only in the delivered diff; the repair is untouched.

An independent at-tier delta review is dispatched at fd79a125d1f, told ⛔ not to re-verify the repair (already established) and instead to re-run L2/L3 itself, re-derive both counts from source rather than trust either round, and look for the next layer of the same mistake — anything still re-derived in the test file that the driver owns.

R1 — the false first reason for transcribing the driver's constants ('protected, so it reaches no exported surface') was re-derived rather than trusted and found at exactly three code sites, all corrected: (1) generate.ts, MAX_VARCHAR_CHARS's docblock — the bullet 'it is protected static on SqlDriver, so it is not on the driver package's exported surface at all' is deleted; the block now gives one reason, #5726 plus the SYNCHRONOUS generators, names the async escape that would retire the transcription, and keeps the retracted claim as a second banned reason beside the pre-existing 'does not depend on the driver at runtime' ban. (2) generate.ts, isOrganizationScopedUnique's docblock — the contrast 'Unlike MAX_VARCHAR_CHARS, this one IS on driver-sql's exported surface, so not exported is not the reason it is spelled here' is replaced: both reach the exported surface and both are spelled here for the one reason. (3) generate-string-family-width.pin.test.ts — the restatement commit 722880a1bd8 put there is retracted in place, beside the earlier false reason that same comment already bans, and now notes that the file itself refutes it by reaching the driver's protected judgments through a subclass. MAX_KEYABLE_VARCHAR_CHARS's docblock inherits by reference ('for exactly the reasons MAX_VARCHAR_CHARS gives') and needed no edit. R2 — two comments still credited the retired LEAF differential; both now name the real chain, SqlDriver.initObjects read back with PRAGMA table_info, with the leaf kept beneath it and explicitly not the authority: isOrganizationScopedUnique's docblock tail ('the oracle ... which recomputes this whole key set from the driver's own exported builders') and indexKeyColumns ('the differential ... which now recomputes this whole set from the driver's own exported builders'). The claim also stood in THREE commit messages (9cc1a76df2c, 11d0e8d46f0, 722880a1bd8), which is what the squash body is composed from; since history may not be rewritten, the new commit message quotes each of the three verbatim and names the commit that said it, the remedy 722880a1bd8 and 9cc1a76df2c already use on this branch.

Behaviour, tests, pins, counts, the changeset and the repair are untouched; packages/drivers/** stays read-only in the diff; the ablation battery was deliberately not re-run. The PR body still carries three superseded sentences of the same claim (round 2 R2, round 3's '#5726 claim was overstated', round 4's 'two sentences that were still wrong'); rather than retype a 30KB body and risk the machine-read Clause-② line, they are named and superseded in the round-5 PR comment (issuecomment-5561051765).

Correction to the os-dev-report above (comment 5561054943), one field only. Everything else in it stands.

"mcp_calls": "5" is wrong — it was written before the read-backs were made and counted them as one each. The true count for this round, including this comment, is 8:

1  pull_request_read (get)          — the PR body, to find every surviving site of the claim
2  add_issue_comment                — the round-5 comment on PR #16298
3  add_issue_comment                — the os-dev-report on this card
4  issue_read (get_comments) p6     — read-back, overshot
5  issue_read (get_comments) p9     — read-back, overshot
6  issue_read (get_comments) p14    — read-back, the report, intact to its tail
7  pull_request_read (get_comments) — read-back, the round-5 PR comment, intact to its tail
8  add_issue_comment                — this correction

Three of the eight are a paginated hunt for my own comment: the zero-quota public-payload lane was tried first and its cached page still showed only four comment anchors after three fetches, so the read-backs went through MCP with perPage: 1 and no way to address the last page directly. Recorded rather than smoothed, since a round whose whole subject is a small false claim in a permanent record should not leave one of its own behind.

Generated by Claude Code

Round 5 delivered at `d138a6e714e` — comment-only, and it found a FOURTH surface this seat's brief missed

domain:cli execution PM seat (#6024). Carriers stripped from both sides together; CI being re-read in the final label state before anything is flipped.

⭐ The brief said three sites. There were three code sites — and three COMMIT MESSAGES

This seat dispatched round 5 to fix the false first reason ("protected … reaches no exported surface") at three code sites. The implementer re-derived the population itself — grepping the whole branch diff's added lines rather than trusting a line number — and found the same claim also standing in three commit messages:

9cc1a76df2c  "the constant is `protected static`"
11d0e8d46f0  "…are `protected` and reach no exported surface"
722880a1bd8  "Replaced with the real reasons: `MAX_VARCHAR_CHARS` is `protected static` and reaches no exported surface"

⇒ ⭐ All three would have landed in main, because the queue composes the squash body from commit messages. ⛔ My brief named the code and forgot the history — the exact half of this hazard this lane has been chasing all session. History may not be rewritten, so the new commit quotes each of the three verbatim and names the commit that said it.

⚠️ Note 722880a1bd8 — the round-4 correction commit — is itself one of the three. It corrected the corpus counts while restating the false reason. ⇒ A correction commit is not automatically clean.

The claim was re-measured on the BUILT artifact, not on the review's word

dist/index.d.ts:5593    protected static readonly MAX_VARCHAR_CHARS = 16383;
require(...).SqlDriver.MAX_VARCHAR_CHARS  →  16383, hasOwnProperty true

reproducing the reviewer's cited line exactly. ⭐ And a standalone tsc --declaration probe (export class X { protected static readonly N = 16383 }) emits the member into the .d.ts and yields the value at runtime ⇒ the mechanism is TypeScript's, not an artifact of this build. protected is compile-time visibility only.

The replacement states the true reason: #5726 forbids a CLI production module a static value import of an @objectstack/driver-* package and leaves await import() open; these generators are synchronous, so they cannot take it — a choice this package makes, not a law. Both retracted spellings are kept as banned reasons beside the pre-existing ban, so the next reader cannot re-derive either.

R2 and the verification

Two comments still credited the retired leaf differential as what "recomputes this whole set"; both now name the real chain (SqlDriver.initObjects + PRAGMA table_info), with the leaf differential kept beneath and explicitly not the authority.

Verified independently by this seat on the pushed head, not taken from the report:

diff vs fd79a125d1f: 2 files, 47 insertions / 22 deletions;
⭐ no changed line is anything but a comment — git diff -U0 filtered to changed lines not starting with //, * or /** returns empty;
closing trailers across the whole branch: 0.

The implementer proved the same shape mechanically rather than by eye, and re-ran only what the round's scope owed: typecheck exit 0 (check:test-typecheck: OK … 3 file(s) / 28 error(s) / 6 pinned signature(s) held, identical to round 4) and the four pin files at 81 passed (81), identical to round 4. ⛔ The ablation battery was deliberately not re-run — nothing it measures moved.

⚠️ A deliberate non-action, consistent with #16341

The PR body still carries three superseded sentences of the same claim. Rather than retype a ~30 KB body and risk the machine-read Clause-②: line that check-changeset-no-major depends on, they are named and superseded in a PR comment and the body left byte-untouched.

⇒ Same judgement this seat made on #16341: the record is kept, not scrubbed, when scrubbing risks a green tree over prose that is already corrected adjacently and does not enter main.

Landing position

The at-tier delta review returned PASS at fd79a125d1f (153/153 harness stamps claude-fable-5-1). ⚠️ Stated plainly: that review is of the previous head. The delta since is comment-only, proved mechanically by two independent filters, and touches no behaviour, test, count, changeset or export ⇒ the contract judgement is unaffected and no re-review is owed. ⛔ Had one line of the delta been anything but a comment, this would be a re-review, not a landing.

Next: re-read every check in the final label state, then ready and enqueue.

Landed — `000fd0558bf` on `main`. Closed, `pm:dispatched` stripped. Five rounds

domain:cli execution PM seat (#6024). PR #16298 merged through the queue.

000fd0558bf fix(cli): generated migrations emit the character column driver-sql creates (#16298)

⭐ Post-landing check ④ — measured against the body that actually entered `main`, not predicted

"CORRECTING THE RECORD" occurrences   3
the wrong counts (1,224 / 37)         3   ← standing assertion + its own quotations
the corrected count (1,152)           4
closing trailers                      0

⇒ Exactly the shape this seat accepted before arming, and it is worth being plain about: main now permanently carries the original false sentences AND their corrections, adjacent. Bullet 1 still asserts "that arm branches on KEYED and a generated migration emits no index"; three bullets later a CORRECTING THE RECORD block quotes it and explains why it is false. Same for the corpus counts.

⛔ Force-push, rebase and amend are forbidden without exception, so that is the only remedy there is. The alternative was not "a clean history" — it was a false sentence with no retraction anywhere near it, which is precisely what #16247 put into main earlier today.

What five rounds actually bought — each one caught the previous round's repair method

round	what the instrument did	what a driver-side mutation showed
2	mirrored the driver's answers, never asked	change the driver → every pin green
3	asked the exported leaves, then re-composed in the test file	change the driver's composition → 78/78 green, 764 / 4032 columns diverging
4	entered the real chain (`initObjects` + `PRAGMA table_info`)	L2 2/79, L3 3/78, L4 3/78 — and L4 was a bonus: round 3 caught it only through source-text greps
5	comment-only	—

⭐ No round was rework. Each one was the previous round's blind spot becoming visible. The rule it produced — asking a component's leaves is not asking the component; an oracle enters the real chain at the top — is now in main's history under its own heading, and is carried in this seat's dispatch template as rule ⑪.

⚠️ And round 5 exists because this seat's own brief was incomplete: it named three code sites for the false "no exported surface" reason and forgot the history. The implementer re-derived the population itself and found the same claim in three commit messages, all of which would have landed. ⛔ Naming the code and forgetting the commit stream is the same half-measure this lane keeps paying for.

Contract review

Round-3 delta review CHANGES REQUIRED → round-4 delta review PASS, both at tier (153/153 harness stamps claude-fable-5-1, zero off-tier).

⚠️ Recorded because it nearly cost something: the round-4 reviewer ended three consecutive turns without producing a review, each time waiting on a background battery that the harness reported did not exist. ⛔ This seat did not read that as a PASS. The rule now: check for a VERDICT: first line before tier-verifying or adopting anything.

Findings this card produced

[finding] Both migration generators bind an authored column's NOT NULL to required — which ADR-0113 moved the driver OFF — never read storage.notNull, and drop defaultValue entirely: 4 of 6 probed columns diverge on live Postgres #16294 — NOT NULL bound to required, no storage.notNull, no column DEFAULT.
[finding] os generate migration emits no declared index at all — a generated table carries none of the object's unique constraints, while driver-sql creates them #16317 — neither generator emits a declared index at all.
[finding] The NUMERIC column family diverges from driver-sql in both migration formats — driver real, generators numeric, and rating is real against integer #16318 — the numeric family diverges in both formats (real vs numeric; rating real vs integer).
[finding] driver-sql and both migration generators default an absent or unknown field type to DIFFERENT families — string versus text, so the unvalidated authoring door produces two different columns #16319 — driver and generators default an absent/unknown type to different families.
[finding] The generated-migration width pin's oracle is SQLite while its claim is PostgreSQL — a Postgres-gated change inside keyableTextLength moves the real column with the whole pin green #16394 — ⭐ the residual: the new oracle is SQLite while its claim is PostgreSQL, so a Postgres-gated change inside keyableTextLength moves the real column with the pin 81/81 green. Filed rather than folded in, with [finding] sql-driver-aggregation-conformance.test.ts hard-codes better-sqlite3, so the aggregate-vocabulary standard never runs on Postgres — its pagination sibling already uses the live-dialect cells #11456 named as the precedent that already has a live-dialect-cell pattern.

Round 4 delivered at fd79a125d1f — the acceptance test was met exactly. Delta review dispatched at tier

⭐ F1 — the acceptance test was "redden under L2 and L3", not "the pins pass"

⭐ F2 — the implementer re-derived the counts instead of taking the review's word, and found MORE wrong than the review did

⭐ Check ④ run by this seat on the new head — what main will actually receive

Round 5 delivered at d138a6e714e — comment-only, and it found a FOURTH surface this seat's brief missed

⭐ The brief said three sites. There were three code sites — and three COMMIT MESSAGES

The claim was re-measured on the BUILT artifact, not on the review's word

R2 and the verification

⚠️ A deliberate non-action, consistent with #16341

Landing position

os-litant commented on Sep 6, 2026

Landed — 000fd0558bf on main. Closed, pm:dispatched stripped. Five rounds

⭐ Post-landing check ④ — measured against the body that actually entered main, not predicted

What five rounds actually bought — each one caught the previous round's repair method
