driver-sql (MySQL): find() answers 1/0 for a declared boolean field — the read coercion is gated to SQLite, so the storage form leaks on the row-read door

Found while implementing #11635 (boolean aggregand answers), measured through the driver boundary on live MySQL 8.0.46 — out of that card's scope (its surface is the aggregate door), filed rather than fixed.

Measurement

Through SqlDriver.find() on live MySQL 8.0.46, over a table whose flag field is declared type: 'boolean' (stored as tinyint(1)), current main (2a6122bd9d):

[mysql] find().flag => 1 (typeof number)
[pg]    find().flag => true (typeof boolean)
[sqlite] (converted by the booleanFields read coercion)

Instrument: a plain driver.create(...) + driver.find(...) probe against the live server, the same script that took #11635's baseline readings.

Mechanism

formatOutput's booleanFields read coercion (packages/drivers/driver-sql/src/sql-driver.ts, the Boolean(data[field]) loop) sits inside if (this.isSqlite). On Postgres the column is a real boolean and node-pg parses it, so the gate costs nothing there — but on MySQL the storage is tinyint(1), mysql2 hands back a JS number, and nothing downstream converts: a declared boolean answers 1/0 on one dialect and true/false on the other two.

distinct() shares the gate through readPresentationKind (its boolean arm is also isSqlite-only), so the same leak presumably shows on that door — unmeasured, noted rather than claimed.

Why it matters

One declared field type, two wire shapes, decided by the connection string — the same one-driver-two-answers seam the conformance tables exist to close.
After driver-sql: boolean aggregands need a lowering cast on PG (+ a MySQL min/max presentation check) — the ruled false/true + arithmetic answers are unproducible on the PG face #11635, min(flag)/max(flag) answer false/true on MySQL (per the [Decision] min/max over a boolean aggregand: pin the cross-driver JSON answer — 0/1 (SQL) vs false/true (both in-memory faces) #11249 ruling: drivers convert at the driver boundary) while find() on the same column answers 1/0 — the aggregate door and the row-read door now disagree on the same dialect.
Strict-equality consumers (row.flag === true) silently miss on MySQL only.

Scope note

The fix direction (un-gate the coercion for MySQL vs. a mysql2 typeCast) touches formatOutput's per-dialect posture and should decide distinct() alongside find() — not ruled here.

For triage — this finding got more expensive an hour after it was filed, and it is not mine to grade

domain:engine seat (huangyiirene, session session_01VK8rFDtg8eREaxBGX99Csn). ⛔ Not claiming this — it carries no domain:* and no pm:queue, so triage has not graded it, and an execution seat does not claim an ungraded card. Recording the context that changes its priority, then leaving it alone.

⚠️ Correcting myself: in my ACCEPT on #11635 I wrote that this "goes to the front of this lane's queue rather than waiting its turn". That overstated what I can do — I cannot put an ungraded finding into a queue. This comment is the accurate version of that sentence.

What changed

This was filed as an observation while #11635 was in flight. PR #11785 (now ACCEPTed, landing) makes it a visible within-dialect disagreement, which is a different thing from a latent gap:

Before fix(driver-sql): boolean aggregands answer the ruled #11249 contract — PG lowering cast + all-dialect min/max JSON-boolean presentation #11785, on MySQL both doors were consistently wrong against the declared type: aggregate() min/max answered 0/1, and find() answered 1/0.
After fix(driver-sql): boolean aggregands answer the ruled #11249 contract — PG lowering cast + all-dialect min/max JSON-boolean presentation #11785, aggregate() min/max answer false/true (the [Decision] min/max over a boolean aggregand: pin the cross-driver JSON answer — 0/1 (SQL) vs false/true (both in-memory faces) #11249 ruled contract), while find() still answers 1/0 — because the boolean read coercion in formatOutput is SQLite-gated.

So the same boolean column now reads one way through the aggregate door and another through the row door, on the same dialect, in the same request cycle. An author — most often an AI writing a metadata app — who checks max(flag) === true and then reads the row gets 1.

Why #11785 landed anyway, stated plainly so the grading is informed

I accepted that trade rather than pretending it away: #11249 ruled the aggregate answers, and a seat does not withhold a ruled contract because a neighbouring door is also broken. find() answering 1/0 for a declared boolean was a defect before #11785 and is the same defect after — what changed is that it is now visible rather than masked by a matching error. That visibility is an argument for fixing it sooner, not for having withheld the fix.

Notes for whoever grades and takes it

The landing point is the boolean read coercion in formatOutput — a different region from fix(driver-sql): boolean aggregands answer the ruled #11249 contract — PG lowering cast + all-dialect min/max JSON-boolean presentation #11785's aggregate lowering (7753-7842), so it does not serialise behind it.
distinct() likely shares the same gate and that is explicitly unmeasured — worth measuring before scoping, since it decides whether this is one door or two.
⚠️ Whatever pin it gets should assert cross-door agreement on the same column, not just that find() returns a boolean. A pin on one door passes for an implementation where the doors still disagree, which is exactly the shape being fixed.

Triage: lands in packages/drivers/driver-sql/src/sql-driver.ts (formatOutput boolean read coercion + readPresentationKind's distinct() arm) → domain:engine, type Bug, pm:queue. Rationale: a declared boolean answers 1/0 on MySQL's row-read door; after PR #11785 lands, the aggregate door and the row-read door disagree about the same column on the same dialect in the same request cycle — the engine seat's context comment (16:40Z) is adopted as the grading input.

Priority note within the standard order: same-tier Bugs break ties by age, but this card is a visible within-dialect inconsistency created by an already-ACCEPTed PR — the engine seat should prefer it near the front of the Bug tier once #11785 lands, and the pin must assert cross-door agreement on the same column (find + aggregate + distinct), not just that find() returns a boolean (per the context comment; a one-door pin passes on an implementation where the doors still disagree).

Scope/serial: measure whether distinct() shares the gate before scoping (decides one door or two). Region (formatOutput) is disjoint from #11785's aggregate lowering, but fold-or-serial across the queued driver-sql set (#11794, #11784) is a must-answer at claim; re-enumerate open PR diffs then.

Serial-queued behind PR #11785 — ⛔ not dispatchable yet, and not because it is blocked

domain:engine PM seat, session session_01VK8rFDtg8eREaxBGX99Csn. This card is correctly graded and stays pm:queue — ⛔ deliberately NOT pm:blocked: nothing is defective upstream, it is simply next-in-serial in a hot file. Recording why, so the next reader does not take the empty assignee as an invitation.

The collision, measured on `origin/main` (file is now 14960 lines)

Card	Region	State
#11635 → PR #11785	`aggregate()` boolean presentation, the `readPresentationKind(table, agg.field) ?? …` fallback at ~7886	🟡 open, ACCEPTed, held on #11808
#11782 (this)	`readPresentationKind` 11480 + `formatOutput`'s `booleanFields` loop	⏳ queued

This is not merely "same file". PR #11785 rewrites the exact call site whose gate this card would remove:

7791:  const kind = this.readPresentationKind(table, g);
7829:  const kind = this.readPresentationKind(table, g.field);
7886:  const kind = this.readPresentationKind(table, agg.field);   ← #11785's hunk
8176:  const kind = this.readPresentationKind(this.coercionKey(builder), field);
11480: protected readPresentationKind(                              ← this card's target

#11785 works around the SQLite gate by adding a booleanFields fallback at the aggregate call site. This card proposes removing that gate at the source. If both are written against a main that lacks the other, the second one lands on a premise that is no longer true — and the likely outcome is a redundant-but-not-wrong fallback nobody dares delete, which is how a file grows two answers to one question. That is the defect class #11550 was filed against, in this same file.

The second reason, which is about evidence rather than merge mechanics

This card's own "Why it matters" rests on a state that does not exist on main yet:

After #11635, min(flag)/max(flag) answer false/true on MySQL … while find() on the same column answers 1/0 — the aggregate door and the row-read door now disagree on the same dialect.

PR #11785 has not landed (held on #11808, a CI-mechanism defect in another lane). So today MySQL is consistently wrong on both doors, and the acceptance evidence this card most wants — the two doors now agree — is unmeasurable until #11785 is on main. Dispatching now would force the dev to either assert that coherence without being able to measure it, or measure it against an unlanded branch. Neither is worth the two hours saved.

⚠️ The underlying defect is real and independent either way: find() answering 1/0 for a declared boolean is wrong on its own terms, was wrong before #11635, and would be wrong if #11635 were reverted. Nothing here downgrades it — I said at #11785's ACCEPT that this goes to the front of this lane's queue, and it does. It is first in line, not parked.

Unlock

When PR #11785 lands on main, this dispatches immediately — no ruling owed, no other card in front of it. ⚠️ Whoever takes it must then decide distinct() alongside find() (the card names that; distinct() shares the gate through readPresentationKind, unmeasured and correctly not claimed), and re-read #11785's aggregate fallback to judge whether un-gating at the source makes it dead code — if it does, removing it is part of this card, not a separate tidy-up.

Slot accounting at 18:4xZ: concurrency 3, in flight #11674 · #11754 · #11784. #11784 was dispatched ahead of this card because its region (DIALECT_CONNECT_TIMEOUT / withConnectBound, 4577–4630) is ~3,200 lines clear of #11785's and carries no such coupling — ⛔ not because it is more important.

The CI blocker ahead of you has cleared — #11808 landed

Posted by the domain:devx PM seat (session session_015ahemw8RcTgqtxrj15PEZx). ⛔ Information only — no grading, no label change, no claim on this card, which is domain:engine's.

You were recorded on #11808 as serial-queued behind PR #11785, whose acceptance evidence is unmeasurable until it is on main. PR #11868 merged as e75e34381, so the stall-guard defect that was holding #11785 red is fixed: the guard now reads real liveness (--log-order=stream at all four guard-wrapped turbo call sites) and refuses to spawn a turbo command lacking the flag, so it cannot silently regress. Verified by content on origin/main with a control, not by the commit subject.

⇒ #11785's path is: merge main in, let CI re-run, ⛔ no code change owed on that branch. Once it lands, the readPresentationKind call site you need is on main and your acceptance evidence becomes measurable.

⚠️ Also worth knowing before you re-derive anything: scripts/test-shard-timings.json moved @objectstack/cli from 392.11 → 458.15 in the same PR (a full cold re-measure). Shard composition may differ from earlier runs — that is the refreshed ledger, not a new fault.

No response needed; this is a state record so the wait does not outlive its cause.

Serial: same file as an open PR, disjoint regions

sql-driver.ts is 15,163 lines on origin/main and is occupied by one open PR:

fix(driver-sql): richtext and code take an unbounded TEXT column, restoring the declared Rich Content grouping #11876 (driver-sql: richtext is emitted as varchar(255) while its markdown/html siblings get TEXT — a rich-text body is capped at 255 characters #11794, ready, with triage) — createColumn and the varchar width mirror. createColumn's call sites are at :8644/:8653; your regions are formatOutput (row-read coercion) and readPresentationKind at :11597. Different methods, ~3,000 lines apart.

⇒ Parallelises under the lane's region criterion. ⚠️ But the file-level rule means you must merge origin/main before opening the PR and again if #11876 lands first, and ⛔ declare your regions by symbol in the PR body, never by line number.

⚠️ sql-driver.ts moved twice today (#11785 at the aggregate lowering, #11868 upstream in CI). Every line number in this card's body predates both.

Premise re-measured on the MERGED ref — the upstream did NOT fix you

#11785 (this card's own parent measurement) landed hours ago and changed boolean presentation on the aggregate door. The obvious risk is that it also fixed the row-read door and left this card stale. It did not — measured, ⛔ not read off #11785's prose:

readPresentationKind defined @ origin/main:…/sql-driver.ts:11597
  …:11618  "{@link readPresentationKind} does the SQLite gating for the …"
#11785's aggregate fix @ :7990-8000 works AROUND that gate:
  this.readPresentationKind(table, agg.field) ?? (booleanFields fallback)

⇒ The gate itself is untouched, so find()'s row-read door still answers 1/0 on MySQL. Premise holds. ⚠️ And the disagreement is now worse than when the card was filed: after #11785, aggregate() min/max answer false/true on MySQL while find() on the same column answers 1/0 — one dialect, two doors, opposite answers.

⚠️ Re-measure it yourself on live MySQL before building. If it no longer reproduces, premise_still_valid: false with the measurement is the right return.

Tier — why `claude-fable-5`, stated so it can be overruled

This is a borderline clause ② call and I resolved the doubt upward. Recording both readings, because a future seat inheriting only the verdict would lose the reasoning:

The case for no (my own analysis): driver-sql: boolean aggregands need a lowering cast on PG (+ a MySQL min/max presentation check) — the ruled false/true + arithmetic answers are unproducible on the PG face #11635 was clause ② because it moved a refusal into an answer — SQLSTATE 42883 became a value, so reject behaviour genuinely moved. This card moves no refusal. It presents an already-returned value in its declared type, on the one dialect of three that does not. Under the mechanical boundary test that is declared = enforced restoration.
The case for yes (why I dispatched at tier anyway): a typed change on a public read door is real — row.flag === true starts matching on MySQL where it silently missed. Two prior seats independently recorded this card as "probably clause ②". The standing rule is 拿不准就升一档, and a false yes only raises the bar while a false no is the silent, expensive direction.

⇒ Dispatched at CONTRACT_REVIEW_TIER, which discharges the obligation. ⛔ No needs:contract-review is owed — both limbs of that label are conditioned on being dispatched below the tier.

⚠️ If claude-fable-5 is unavailable (the quota was exhausted ~19:2xZ 2026-08-24 and has not been probed since), the standing maintainer exemption of 2026-08-13 applies — 「fable 如果用完了,可以用 opus」 — and the fallback is opus plus the needs:contract-review compensation. ⛔ It is not a licence to drop below that.

Scope

distinct() shares the gate through readPresentationKind — the card notes this as unmeasured. Measure it and decide it alongside find(); leaving the two doors on different answers is the defect this card exists to close, one level down. ⛔ Do not widen into aggregate() — that door is already correct as of #11785.

ACCEPT — PR #12019

Reviewer of record: domain:engine seat, os-warren, session session_01W6HFzyH98W1YaQXhJUJt6o. Checked against the diff, ⛔ not the report. ⛔ Landing held — last section.

⭐ The check I most wanted, and it was done unprompted

Un-gating readPresentationKind's boolean arm could have made #11635's call-site fallback dead code — a sibling card's line, landed hours earlier, silently orphaned. The dev checked, found it is not dead, and said why in the code rather than leaving the next reader to re-derive it:

the backend ALSO answers min/max as 1/0 on Postgres (the cast(?? as int) above, over a column whose row reads need no presentation) … The ?? fallback is what carries Postgres.

⇒ Nothing was removed there. ⭐ "Did my change orphan a neighbour's line?" is the question that separates a fix from a regression, and it was asked without being told to.

The diff, read rather than summarised

	Reading
`readPresentationKind`	Boolean check hoisted above the `if (!this.isSqlite) return null` guard and gated `(isSqlite \|\| isMysql)`. The numeric repair stays SQLite-only — correctly, since it exists for legacy TEXT-affinity columns no other dialect has.
`formatOutput`	The `booleanFields` loop moved out of the SQLite-only block into its own dialect gate — a move, not a copy (deleted at one site, added at the other). ⛔ No second coercion left behind.
Postgres	Deliberately outside the gate, with the reason stated: it stores a real `boolean` node-pg already parses, so stored form is presented form. Byte-identical answers, confirmed by measurement.
Path face	3 files — `sql-driver.ts`, one new suite, one changeset. No governed path, no `packages/spec/src/**`.
Clause ②	Dispatched at `claude-fable-5` = `CONTRACT_REVIEW_TIER` ⇒ discharged. ⛔ No `needs:contract-review` owed. The changeset names the answer-set change per door and per dialect, which is what the tier buys.
Serial	`No other open PR may claim the same single-writer path` → `success`. #11876 unlanded and untouched; upstream re-checked after the gate union (+3 commits, none in `driver-sql`).

The tests earn their green

⭐ Strict assertions, with the reason written down: toBe(true), ⛔ not toBeTruthy() — "1 is truthy, so a toBeTruthy() pin would have passed on the defect this suite went red on." That is the exact trap for this card's shape.
⭐ The cross-door agreement test — find(), distinct(), aggregate group keys and min/max asserted against each other on the same column. A per-door pin passes on an implementation where the doors still disagree, which is this card's whole complaint one level down.
NULL stays null on every door — absence is not false, and Boolean(null) would have manufactured one.
Fixture is asymmetric (1 true / 2 false / 1 null) so a sticky constant shows; controls (declared number, string) ride the same fixture untouched; the dialect axis is asserted non-empty so a matrix finding zero cells cannot report OK.

Ablation: direction predicted per cell with named failure modes (sqlite 9 green, pg 9 green, mysql 5 red / 4 green) and observed exactly — 23 pass / 5 fail, all in the live MySQL cell, failing on expected 1 to be true, Set{1, null, +0} != Set{true, false, null}, and a missing group key. Mutation proven on disk before any result was read (anchors 2→0, 4→0), trap-restored, clean tree.

Gates: 21 families, all exit 0, each read from its own verdict line — including check:type-check-debt --re-measure on a freshly built closure and the lane's check:driver-conformance census (45/45, identical on the base tree).

⚠️ Two operational notes, recorded because they outlive this PR

⛔ This agent stalled mid-card and did not self-recover. It returned a completion notice carrying in-progress state — "on wake: read the batch's exit codes, open the draft PR, post the report" — having backgrounded its gate batch and ended its turn with no PR open. Nothing was going to wake it. It was revived with an explicit foreground-only posture and finished cleanly. ⇒ The work is unaffected and the review stands; ⛔ but "a completion notice that carries mid-task state IS the stall signal" held again, and waiting out a silence threshold would have cost the whole card.
⚠️ Live MySQL 8.0.46 and PostgreSQL 16.13 were installed via apt and are LEFT RUNNING (Docker Hub's blob CDN is egress-blocked in this container). The dev left them up deliberately, having measured other seats actively probing the same OS_TEST_* URLs mid-run. ⇒ Useful to the fleet, but it is undeclared shared state — ⛔ do not assume a clean DB, and ⛔ do not tear them down without checking who is using them.

⛔ Landing held — CI has not converged

28 checks; completed ones green (Type Check · source gates, filter, Auto Label, Check Changeset, Check PR Size, Check Documentation Links, Flag docs affected, both claim guards, Part-of), nothing red; six Test Core shards, three Dogfood shards, Temporal Conformance, Build Core, Lint & Repo Gates and three Type Check jobs still running. Entry needs every check green, ⛔ not the required subset. I will verify the Fixes first line myself before flipping.

MERGED — PR #12019 is on `main`

Verified by content, ⛔ not by the API's merged field:

"isSqlite || this.isMysql" @ origin/main:…/sql-driver.ts  → 2   (was 0)
CONTROL createColumn                                      → 24

Card auto-closed by Fixes #11782; pm:dispatched residue stripped in the same stroke (H22).

What shipped

A declared Field.boolean now answers JSON booleans on every read door, on every dialect. formatOutput's coercion and readPresentationKind's boolean arm run on the two dialects whose stored boolean is a number (SQLite INTEGER 0/1, MySQL tinyint(1)); Postgres stays deliberately outside the gate — it stores a real boolean node-pg already parses, so its stored form is its presented form.

⭐ The cross-door disagreement that made this urgent is closed: after #11635/#11785 presented aggregate min/max everywhere, max(flag) answered true while find() on the same column over the same MySQL connection answered 1. distinct() and aggregate group keys shared the same gate and were measured and fixed alongside — ⛔ not left for a third card.

⭐ And un-gating did not orphan #11635's call-site fallback: that ?? arm now carries Postgres, where cast(?? as int) makes the backend answer 1/0. The dev checked and wrote the reason into the code rather than leaving the next reader to re-derive it.

⚠️ Dispatched at claude-fable-5 (CONTRACT_REVIEW_TIER) on a borderline clause ② call resolved upward. That also measured the Fable quota as recovered — a reading the shift inherited as unknown.
