Replaces Clerk sign-in with Hazel's own auth on @yielded/auth: GitHub and Google sign-in, passkeys, and stateful sessions in Postgres. This PR is the backend and the user migration. It changes nothing at runtime until AUTH_GITHUB_CLIENT_ID is set: the routes aren't mounted and Clerk keeps working exactly as today.

What's in it

  • @hazel/auth/server (packages/auth/src/yielded):
    • auth config: providers, passkeys, sessions
    • Postgres storage mapped onto users plus new auth_* tables (Drizzle schema in packages/db)
    • short-lived ES256 access tokens for the Electric proxy and actors
  • Backend:
    • /auth/*, POST /auth/token and /.well-known/jwks.json
    • The RPC and HttpApi middleware accept the session cookie (trusted Origin required) or the session credential as a bearer token, then fall back to Clerk JWTs and bot tokens.
  • Workers: auth storage uses the request's own lazily-opened Postgres connection, because sockets are request-bound under Hyperdrive. Bun uses one pool.
  • Migration from Clerk:
    • import-clerk-identities.ts links users' GitHub and Google accounts to their existing users.
    • A first sign-in whose provider-verified email matches exactly one existing user is linked to that user, instead of creating a duplicate.

Already done in prd

Details in infra/hazel-auth-rollout.md:

  • Schema applied from packages/db/sql/2026-10-11-hazel-auth.sql. It's additive and was applied by hand, because drizzle-kit push would act on unrelated prd drift.
  • 116 users' GitHub and Google accounts imported (83 Google, 33 GitHub), with no conflicts.
  • Signing keys stored in Infisical prod.

Before turning it on

  • GitHub OAuth App and Google client: callbacks https://api.hazel.sh/auth/{github,google}/callback.
  • The web app's sign-in, register, continue and passkey pages (next PR).
  • Electric proxy and actors verifying the access token.
  • One real sign-in on a preview stage through Hyperdrive.

Tests

  • packages/auth: 12 tests against the real Drizzle schema with per-request connections (needs AUTH_TEST_DATABASE_URL):
    • sign-up and sign-in, sign-out
    • passkey enrollment, access tokens
    • imported accounts, verified-email matching, ambiguous emails
  • apps/backend: the full suite (224) passes. That includes 6 new end-to-end tests of the real wiring against a Postgres container, and new middleware cases.
  • The monorepo typecheck passes (Bun and Worker builds).

Upstream reports: yielded-dev/auth#183 (fixed in beta.32) and yielded-dev/auth#200 (per-request SQL, OAuth crypto layer, identity import).

GitHub and Google sign-in, passkeys and stateful sessions, stored in new
auth_* tables (Drizzle schema in packages/db) with users as the auth
subject. Auth storage runs on a SqlClient routed to the current request's
connection, so it works with the api Worker's per-request sockets.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Mounts /auth/* (GitHub, Google, passkeys, sessions), /auth/token and
/.well-known/jwks.json when AUTH_GITHUB_CLIENT_ID is set. The RPC and
HttpApi auth middleware accept the Hazel session cookie (trusted Origin
required) or the session credential as a bearer token, before falling
back to Clerk JWTs and bot tokens. Auth storage gets a pooled Postgres
client on Bun and a lazily-connecting one per request on the Worker.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- import-clerk-identities links each user's GitHub and Google accounts from
  Clerk to their existing Hazel user (dry run by default, idempotent), so
  their first sign-in lands in their own account.
- A first-time GitHub or Google sign-in whose provider-verified email
  belongs to exactly one existing user links to that user and restarts
  sign-in via the web app's /auth/continue, instead of registering a
  duplicate account.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The auth tables were applied to prd by hand from Drizzle's DDL, since
drizzle-kit push would act on unrelated prd drift. The runbook records what
is done in prd (schema, 116 imported Clerk accounts, secrets) and what is
left before the cutover.

📝 Walkthrough

Walkthrough

The PR adds Hazel authentication with GitHub, Google, and passkey support, PostgreSQL-backed storage, backend cookie and bearer-session authorization, access-token routes, and tooling to import Clerk identities.

Changes

Hazel authentication

Layer / File(s) Summary
Authentication persistence schema
packages/db/sql/2026-10-11-hazel-auth.sql, packages/db/src/schema/auth.ts, packages/db/src/schema/users.ts, packages/db/src/schema/index.ts, packages/auth/src/yielded/tables.ts
Adds authentication tables and user fields for auth status and security revision. Defines corresponding Drizzle schemas and persistence table mappings.
Authentication services and flows
packages/auth/package.json, packages/auth/scripts/generate-keys.ts, packages/auth/src/yielded/*
Adds OAuth and passkey contracts, auth configuration, session policies, identity utilities, storage and SQL layers, HTTP setup, access-token signing and verification, key generation, and integration tests.
Backend routes and request authentication
apps/backend/.env.example, apps/backend/package.json, apps/backend/src/app.ts, apps/backend/src/index.ts, apps/backend/src/rpc/middleware/*, apps/backend/src/services/auth.ts, apps/backend/src/services/hazel-auth*, apps/backend/src/services/hazel-session.ts, apps/backend/src/worker/*
Adds Hazel routes and SQL wiring. Authorization checks cookie sessions before bearer credentials, verifies eligible Hazel bearer credentials, and retains the existing bot-token lookup path. Adds backend tests for session authentication and sign-in flows.
Clerk identity import and rollout
apps/backend/src/scripts/migrate-to-hazel-auth/*, infra/hazel-auth-rollout.md
Adds a dry-run identity import with optional linking and a JSON report. Documents the auth rollout configuration and remaining cutover tasks.

Merge Risk: 🟡 Moderate · up to 7a75a

The Clerk identity import can link provider accounts that were never confirmed as verified, and its dry run does not report ownership conflicts. After sign-in is enabled, linking or unlinking an OAuth account can fail when the stored security revision is not a decimal number. A stale Hazel cookie can also block requests that carry a valid token. Resolve these before relying on the migration or enabling sign-in.

🌐 Web query:

official Clerk Backend API ExternalAccount verification nullable verification status

💡 Result:

Yes. In Clerk’s official Backend `ExternalAccount` type, **`verification` is `null | Verification`**. If it’s an object, its **`status` is non-null** and uses a `VerificationStatus` value: `unverified`, `verified`, `transferable`, `failed`, or `expired`. ([clerk.com](https://clerk.com/docs/reference/backend/types/backend-external-account?utm_source=openai))

So check whether `verification` is null before reading `verification.status`. The docs establish the Backend type; they don’t specify why a particular response might have a null verification.

Require a verified external account before importing it.

verification is nullable, so the current condition accepts an account that Clerk did not report as verified. Apply mode then passes its provider subject to linkIdentity, which writes the OAuth identity and active login credential. Require an explicit "verified" status.

Detect ownership conflicts in the dry run. When --apply is absent, this continue skips the only check that can return Conflict. The report therefore lists a conflicting account as linked and leaves conflicts empty. An operator cannot use the dry run to identify accounts that need manual resolution. Check existing identity ownership before classifying accounts, then reserve writes for --apply.

Restrict access to the import report. The report contains production emails and user IDs. writeFileSync uses permissions affected by the process umask, so a report in a shared workspace can be readable by other local users. Create the export directory with restricted permissions and ensure the report has mode 0600, including when an older report already exists.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

A rejected Hazel cookie blocks every other credential. HazelSession.fromCookie fails with InvalidBearerTokenError in two cases: the Origin is untrusted, or the session is expired or revoked. Both middlewares check the cookie first and pass that failure through with yield*. A browser that keeps a stale Hazel cookie then gets 401 on every request, even with a valid Clerk JWT or Hazel bearer credential. A stale cookie remains after server-side revocation, after the idle timeout, or after a securityRevision change.

Fall through to bearer authentication when an Authorization: Bearer credential is present. Return the cookie error only when the cookie is the only credential.

  • apps/backend/src/services/auth.ts#L24-L29: if Redacted.value(bearerToken) is non-empty, catch the fromCookie failure and continue to the Hazel and Clerk bearer checks.
  • apps/backend/src/rpc/middleware/auth.ts#L41-L45: if the authorization header starts with Bearer , catch the fromCookie failure and continue to the JWT, Hazel-credential and bot-token checks.

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Do not let a malformed AUTH_ACCESS_TOKEN_PRIVATE_JWK put private-key material into logs.

Schema.decodeSync(PrivateJwk) throws inside Option.map, so the failure becomes a defect when the layer is built. If the value is not valid JSON, the error comes from JSON.parse. Current V8 versions include a snippet of the input text in that error message, and Schema issue formatting can also include the actual input. The startup crash log can then contain part of the private signing key.

Decode the value as an effect, and replace the error with a message that contains no secret:

Review comment at @apps/backend/src/services/hazel-auth.ts around lines 86 - 92:
Update the access-token key construction in the layer so decoding
`env.accessTokenJwk` uses an effect rather than `Schema.decodeSync`. Replace
decode failures with a secret-free error before they can reach startup logs,
while preserving the `Option.none` case and the existing
`AccessToken.SigningKey` fields.

🌐 Web query:

official @yielded/auth-persistence subject securityRevision nextSecurityRevision contract

💡 Result:

The official contract appears to treat `securityRevision` as an application-owned value on the subject record. In the managed-table example, you map it with `subjects.securityRevision`; the docs describe it as the subject’s “security revision.” ([yielded.dev](https://yielded.dev/auth/guide/storage/?utm_source=openai))

I couldn’t verify an official documented contract for `nextSecurityRevision`—the official sources I found don’t establish its signature, who calls it, or whether it must atomically increment the revision. So don’t assume a particular implementation from the property name alone. The closest official guidance says custom persistence must recheck relevant account and credential state and commit related changes atomically when required. ([yielded.dev](https://yielded.dev/auth/guide/storage/?utm_source=openai))

If you mean a specific package version, share it: the docs/examples I found don’t identify which published version’s implementation they describe.

🌐 Web query:

"@yielded/auth-persistence@0.1.0-beta.32 source nextSecurityRevision OAuthSubjectTable

💡 Result:

I couldn’t verify `nextSecurityRevision` or `OAuthSubjectTable` in the published source for **`@yielded/auth-persistence@0.1.0-beta.32`**. The available search results identify the project and describe its persistence package, but don’t establish those symbols or that exact version’s implementation. ([yielded.dev](https://yielded.dev/auth/reference/modules/?utm_source=openai))

The current docs describe `securityRevision` as a subject-table mapping option, but they don’t confirm whether either named symbol exists in beta.32. ([yielded.dev](https://yielded.dev/auth/guide/storage/?utm_source=openai))

Use a format-compatible revision generator for OAuth subjects.

The composed persistence generates subject revisions from base64url-encoded random bytes. Hazel’s OAuth mapping passes those revisions to BigInt(current). A non-decimal revision can therefore throw during provider linking or unlinking.
