…vers
Phase A of the Drizzle 1.0 upgrade: the ORM and kit move to 1.0.0-rc.4
while Workers stay on postgres-js and tests stay on PGlite, so the query
compiler and migration tooling change in one deploy and the wire driver in
another.
- Migrations folder converted with `drizzle-kit up` to the v1 layout, one
`<timestamp>_<name>/` folder per migration with `migration.sql` and a DDL
snapshot, no journal. Four hand-authored migrations never had a snapshot
and stopped the converter; their snapshots are synthesised from exact
neighbours and re-linked. Every migration.sql is byte-identical to the
old file so the migrator's hash backfill matches production rows.
- The converter serialises partial-index WHERE clauses table-qualified and
a fresh schema read does not, so the head snapshot's ddl is replaced by
the generated one; `generate` is a no-op and `check` passes.
- `readBundledMigrationsSql` walks the folders; the migrations test checks
folder timestamp order instead of journal idx/when.
- `drizzle()` lost the `(client, config)` overload and the RQB-only `schema`
option; constructors use `drizzle({ client, logger })`.
- `getTableColumns` -> `getColumns`; `strict` dropped from drizzle.config and
`schemaFilter: ["public"]` pinned, since v1 manages every schema by default.
- pglite ^0.5.6, the floor `@effect/sql-pglite` will need in Phase B.
Deploy note: run `bun run migrate:prod` before the Worker deploy; the v1
migrator adds `name` and `applied_at` to drizzle.__drizzle_migrations and
backfills existing rows.
Phase 0 ran on top of Phase A with @effect/sql-pg and @effect/sql-pglite at rc.112. drizzle-orm 1.0.0-rc.4's effect layer calls Schema.TaggedErrorClass, the beta.83 name, so it cannot be imported on effect rc.112 or rc.115; with that one symbol renamed in the installed copy, select, transaction and the typed error path all run, and a Context.Reference statement collector is visible to the EffectLogger from the caller's fiber. Raw execute returns the driver's result object rather than rows despite the declared type. Phase B is therefore blocked on a drizzle build compiled against current effect, or on a repo-owned two-file bun patch; the plan says which and leaves the choice to the owner.
…snapshot The previous note said no drizzle build targets current effect. That was read off the dist-tags alone; `npm view drizzle-orm time` shows commit-suffixed snapshots past rc.4, and 1.0.0-rc.5-5935859 (rc5 branch, 2026-09-09) carries the Schema.TaggedError migration from PR #6108. On it the effect-driver spike passes unpatched, all four packages typecheck, and drizzle-kit leaves the converted migrations folder alone. Phase A stays on the tagged rc.4; Phase B's first change is the bump to rc.5, tagged or snapshot at the owner's discretion.
Phase B1 of the Drizzle 1.0 upgrade, on the 1.0.0-rc.5 snapshot that targets current effect. Services and their tests are converted in the commits that follow; this one is the layer they code against. - `Database.execute` takes an Effect callback. Queries are yielded, a transaction takes an Effect callback, and the driver's failures are absorbed into `DatabaseError` at this boundary while whatever the callback failed with on its own passes through (`ExecuteError<E>`). - One drizzle database per invocation over a lazily dialed `pg.Pool`, built with `PgClient.fromPool` (no `SELECT 1` probe) into the invocation's Scope via `Layer.build`. `Effect.provide` would have ended the pool the moment the database was built. - Per-call statement capture is a `Context.Reference` the drizzle `EffectLogger` reads, replacing the per-call drizzle wrapper. - `postgres-errors.ts` classifies on `@effect/sql`'s reason tag with the pg SQLSTATE as `error.type` where there is one; node-postgres never emits `CONNECT_TIMEOUT`, so a stalled dial lands as `ConnectionError`. - `@effect/sql`'s own per-statement spans are suppressed inside the call. - PGlite twin over `@effect/sql-pglite` with `liveClient`, so the snapshot restore and the Date-param guard survive. - `rawRows` normalizes raw `db.execute` results, which the Effect drivers return as the driver's result object despite the declared row array.
Phase B2 of the Drizzle 1.0 upgrade: the call-site sweep over the platform layer from the previous commit. Queries are yielded, transactions take an Effect callback, and the failures a callback raises on its own reach the caller as themselves instead of as DatabaseError prose. - alerts, auth, errors, integrations, org: 26 service files converted, one directory at a time, each with its tests green. - Transaction sentinels that used to be thrown are typed failures now: AlertRuleDestinationNotFoundError / AlertValidationError inside writeRuleRow; SlackCrossOrgConflict; IntegrationsPersistenceError for the PlanetScale finalize paths; TriageActorMissingError, ErrorTickClaimLost (now a Schema.TaggedError matched by instance, not by message) and ErrorTickUpsertMissingRow in the error tick. Every one is folded into the persistence error the caller already handled, so no public error type changed. - Helpers over the old client (issue-severity, investigation-quota, apply-diagnosis, error-tick-persistence, mcp-oauth-family) are Effects over MapleDbLike. - Test doubles: fakes route through executeWithSpan so their type is the real contract; the sabotaged-insert proxies fail with a driver error the way a dead connection would; the raw PGlite client seams go through Database.execute. - apps/ai fan-out workflow and the api's real-Postgres integration test on the new API. drizzle services are built with Layer.build into the invocation scope rather than Effect.provide, which the effect lint reserves for entrypoints. Verified: tsc clean in db, backend, api, ai, alerting; bun run lint clean; frozen lockfile clean; vitest green for packages/backend (1715), apps/api (432), apps/ai (677), apps/alerting (10), packages/db (43).

Remove the obsolete rc.4 deployment question.
The Phase B progress section records the decision to use 1.0.0-rc.5-5935859. This question instead presents an rc.4 production pin as unresolved and states that the rc line has been silent since June. It conflicts with the selected dependency and can mislead a later deployment decision. Replace it with a current open question or remove it.

Summary
Moves the application database onto drizzle 1.0 and its Effect-native drivers, in three steps that are separable if one of them needs to be backed out:
migration.sqlis byte-identical to the old file, so the migrator's hash backfill of production rows matches. Four hand-authored migrations had no snapshot and stopped the converter; their snapshots are synthesised from exact neighbours. The converter also serialises partial-indexWHEREclauses table-qualified, which made the firstgeneraterecreate all 8 partial indexes; the head snapshot is aligned andgenerateis a no-op.@effect/sql-pg(packages/db/src/client.ts,packages/backend/src/platform/*).Database.executetakes an Effect callback; driver failures are absorbed intoDatabaseErrorat that boundary and whatever the callback fails with on its own passes through (ExecuteError<E>). One database per invocation over a lazily dialedpg.Pool(PgClient.fromPool, noSELECT 1probe), built into the invocation scope withLayer.build. Per-call statement capture is aContext.Referencethe drizzle logger reads.postgres-errors.tsclassifies on@effect/sql's reason tag with the SQLSTATE aserror.typewhere there is one.The pin is the
1.0.0-rc.5-5935859snapshot: the tagged rc.4 still callsSchema.TaggedErrorClass(effect beta.83) and cannot be imported on effect rc.112; therc5branch fixed that in August and the snapshot carries it.

No non-prod stage has a database, so the first deploy is the measurement.Verification
