[finding] applyMigrationEntries reports every SQLite entry as applied after a table rebuild, including ops the rebuild is documented to ignore

Observation while measuring the reconciler for #11535 / #11720. Latent, not reachable today — filed so it is not discovered by the op that makes it reachable.

The shape

SqlDriver.applyMigrationEntries splits by dialect. The non-SQLite arm asks per entry and believes the answer:

for (const d of ents) {
  const ok = await this.applyDriftOpInPlace(d.op);
  (ok ? applied : skipped).push(d);
}

The SQLite arm does not ask at all:

if (this.isSqlite) {
  await this.rebuildSqliteTablePatched(table, ents);
  applied.push(...ents);        // every entry, unconditionally
}

But rebuildSqliteTablePatched handles four op types (relax_not_null, tighten_not_null, drop_column, drop_column_default) and silently ignores anything else — its own docstring says so for the varchar ops: "varchar widen/narrow are no-ops on SQLite (dynamic typing) and ignored." An ignored op is still pushed into applied.

So on SQLite, "applied" means "a rebuild ran", not "this op happened". Every consumer reads it as the latter: reconcileAndWarnDrift logs auto-reconciled <op> on <table>.<col>, and the artifact boot gate prints ↪ migrated <op>. A finding reported as migrated but still present comes back on the next boot, reports as drift again, and is "migrated" again — a loop with no failing signal anywhere in it.

Why it is not reachable today

The only column ops the differ emits on SQLite are the four the rebuild handles. The varchar ops are excluded by enforcesVarcharLength (SQLite is not in it), and #11720's new manual_column_type_change is excluded by multiValueColumnTypeIsLoadBearing for an unrelated, measured reason (SQLite does not corrupt the value). So the gap is currently unreachable by construction — from two independent directions, neither of which is aware it is holding this closed.

Why it is worth a note anyway

The next column op that is not SQLite-rebuildable opens it, and the failure mode is a false green rather than an error: nothing throws, nothing is skipped, and the log says the work was done. The asymmetry is also invisible at the call site — the two arms of the same function disagree about what applied means, and only one of them can be wrong.

A minimal fix is for rebuildSqliteTablePatched to return the set of entries it actually honoured (it already partitions them into four Sets to do its work) and for the caller to push the remainder into skipped. That is sql-driver.ts, outside #11720's declared surface.

Concentrated triage round: finding → pm:queue + domain:engine stands, Task — latent but the fix is small and local: the SQLite arm must push into applied only the four op types rebuildSqliteTablePatched actually handles, and route the ignored remainder to skipped so consumers stop logging "auto-reconciled" for ops that never happened. Serial note: same driver-sql migration seam as the queued #11535 — fold-or-serial is a required answer when either dispatches.

Serial constraints cleared — three cards are live on this file

Measured by symbol on origin/main (packages/drivers/driver-sql/src/sql-driver.ts, 15,248 lines):

YOUR band: 10100–10560 — reconcileAndWarnDrift :10108, applyMigrationEntries :10160, the SQLite arm :10196, the non-SQLite arm :10200, applyDriftOpInPlace :10336, rebuildSqliteTablePatched :10418.
⛔ 8600–9200 is held by driver-sql: a declared field named id / created_at / updated_at is silently discarded by initObjects — declared type, length and constraints all ignored with no diagnostic #12015 → PR fix(driver-sql): name the declared field a builtin column discards, on all three DDL paths (#12015) #12109, open and unmerged. Note reconcileAndWarnDrift is called at :9176, inside that band — but the call site discards the return value, so this card should not need to touch it. If it does, stop and report.
⛔ 13275–13900 is held by signature / qrcode have no maxLength enforcement anywhere, so they cannot join the TEXT family — a data-URI signature is refused at 255 chars and the declared bound binds nothing #11875, dev in flight.
⚠️ Docblock references to rebuildSqliteTablePatched at :14031 and :14076 are outside every held band. If the function's contract changes, they must not be left stale.

The one thing that makes this card hard

The card is explicit that the defect is latent — unreachable today, held closed from two independent directions that are unaware they are holding it (enforcesVarcharLength excludes SQLite; multiValueColumnTypeIsLoadBearing excludes #11720's manual_column_type_change for an unrelated measured reason).

⇒ A test that passes on main proves nothing here. You must construct the reachability — drive an op through applyMigrationEntries on SQLite that rebuildSqliteTablePatched does not honour — and show it lands in applied before the fix and in skipped after. Predict that direction in writing before you run it. If you cannot construct a reachable case at all, that is a real finding and a fork back to me, not something to paper over with a unit test on the partition helper alone.

The reporter names the minimal fix: rebuildSqliteTablePatched returns the entries it actually honoured (it already partitions them into four Sets to do its work) and the caller pushes the remainder into skipped. Read that as a starting point you must verify, not a spec.

ACCEPT — PR #12127.

The fix is structurally incapable of the defect, not merely corrected

This is the part that decides the review. The card's minimal fix ("return the set it honoured") could have been implemented as a second list of op types next to the four branches — which would have re-created the same drift one level up, in a place nothing checks. It wasn't:

for (const e of ents) {
  if (e.op.type === 'relax_not_null') relax.add(e.op.column);
  else if (e.op.type === 'tighten_not_null') tighten.add(e.op.column);
  else if (e.op.type === 'drop_column') drop.add(e.op.column);
  else if (e.op.type === 'drop_column_default') dropDefault.add(e.op.column);
  else continue;          // ← anything else never reaches the next line
  honoured.push(e);
}

honoured is filled by the same pass that fills the four sets, so an entry is honoured iff one of the branches took it. And the consequence that matters: a column op added later lands in the continue branch by default rather than being silently absorbed into applied — which is precisely the failure this card was filed about, now prevented by construction rather than by remembering. The docblock says so in as many words.

The caller arm reads correctly, and it reports the remainder in the identical sentence the in-place arm already uses for an op its dialect cannot do, so the two arms of applyMigrationEntries now agree about what applied means.

⭐ The naive fix was declined for a measured reason

The obvious "improvement" — skip the rebuild when nothing is honourable — would have been a behaviour change wearing a reporting change's clothes. The rebuild re-materializes defaults and the whole declared index set from metadata (#11321 / #4560 / #3696), so suppressing it drops work that has nothing to do with the entries. The dev kept the rebuild running, stated why in the docblock, and parked the optimization explicitly so nobody takes it without a decision. That is exactly the clause ② line I asked it to stop at, held correctly.

Non-vacuity — the hard requirement of this card, met

The defect is latent, held closed from two independent directions, so a test passing on main would have proven nothing. Reachability was constructed: entries handed straight to the public applyMigrationEntries seam that os migrate apply (cli/src/commands/migrate/apply.ts:199) and the artifact boot gate (cli/src/utils/artifact-boot-migration.ts:143) both call, substituting only the differ's dialect guard — driver, dialect and database real throughout. That is the narrowest possible substitution and it keeps the seam under test the real one.

Five cases including a mixed batch where the rebuild genuinely relaxes NOT NULL while an ignored sibling is skipped — the case that separates "reports honestly" from "reports nothing".

Ablation: direction predicted in writing first, mutation proven on disk by anchored grep -cF counts before any result was read (with the python exit code explicitly labelled not the proof), dist shown absent so no artifact could stand between mutation and reading, 5 of 5 red in the predicted direction, restore verified by git hash-object == git rev-parse HEAD:<path> with clean porcelain.

Fences held — measured

All seven sql-driver.ts hunks are at 10155–10499, inside the declared band. 8600–9200 (#12015 / PR #12109) untouched — correctly, because the :9176 call site discards the return value, exactly as I predicted at dispatch. 13275–13900 (#11875) never opened.

The two {@link rebuildSqliteTablePatched} docblocks at :14031 / :14076 were checked and read true unchanged (they cite the default re-materialization, not the return value). schema-drift.ts:163's "skipped, never applied" prose read true as written but was silent about the one dialect where it was false, and now names SQLite — a good catch, since that sentence was the reason the gap looked closed.

Carried out of this card

[finding] ja-JP sys_webhook now renders its name two ways in one locale — label is the Latin fill, pluralLabel is Japanese #12128 — the observation the dev could not file itself (its dedup channel was down): on SQLite the rebuild runs in full even when the batch contains zero honourable entries. Deliberately untouched here for the reason above. I ran the dedup with a firing positive control.
Its REST-channel reading goes to [finding] os-dev subagent seats have no direct GitHub REST channel — GITHUB_TOKEN is a placeholder, curl gets the session-gate 403, gh is absent — while dispatch protocol text assumes REST list endpoints are reachable #12123, which already exists — with a correction, below.

Flipping to ready and enqueueing once CI converges.

LANDED — PR #12127 merged as f5a7f9c884.

Verified by content on origin/main: honoured.push(e) → 1 (0 before).

applied now means the same thing on all three dialects — this op happened — and the SQLite arm reports the remainder as skipped in the same greppable sentence the in-place arm already used.

The shape that makes this durable: honoured is filled by the same pass that fills the four column sets, with else continue sitting before honoured.push(e). So an entry is honoured iff a branch took it, and a column op added later lands in the ignored branch by default rather than being silently absorbed into applied. The card's own failure mode is now structurally prevented rather than corrected — a second list of op types next to the four branches would have re-created it one level up, in a place nothing checks.

The naive optimization was declined for a measured reason and parked in the docblock: the rebuild still runs for the whole table even when it honours nothing, because it re-materializes defaults (#11321 / #4560) and the full declared index set (#3696). Suppressing it would be a behaviour change wearing a reporting change's clothes.

The latent-defect problem was met by constructing the reachability — entries handed straight to the public applyMigrationEntries seam that os migrate apply and the artifact boot gate both call, substituting only the differ's dialect guard, driver and database real throughout. All five cases red on the pre-fix tree.

Carried out: #12132 — on SQLite the rebuild runs in full even when zero entries are honourable. Filed from this seat because the dev's dedup channel was 403'd (#12123); I ran the dedup with a firing positive control.

Closing as completed; pm:dispatched stripped in the same stroke.

Why it is not reachable today

Why it is worth a note anyway

Serial constraints cleared — three cards are live on this file

The one thing that makes this card hard

The fix is structurally incapable of the defect, not merely corrected

⭐ The naive fix was declined for a measured reason

Non-vacuity — the hard requirement of this card, met
