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

The PR adds Hazel authentication with OAuth, passkeys, PostgreSQL-backed sessions, and access tokens. It replaces Clerk integrations across browser and connected services. It also adds organization invitations, workspace creation, and desktop application update flows.

Changes: Hazel authentication

Layer / File(s) Summary
Auth contracts and persistence
packages/auth/..., packages/db/...
Adds OAuth and passkey contracts, auth policies, identity linking, SQL storage and routing, access-token signing and verification, auth tables, user security fields, and migrations.
Backend sessions and connected services
apps/backend/..., packages/actors/..., packages/auth/src/consumers/proxy-auth.ts, apps/electric-proxy/...

Merge Risk: 🟠 High · up to 244a5

Do not merge without addressing the sign-in fallback and invitation delivery: users may be unable to sign in when Hazel is disabled, and invitations can appear sent without reaching recipients. The identity import and other retained risks also need owner resolution.

- Around line 109-110: Update the account classification flow around
report.linked.push and the !apply guard to check existing identity ownership
before classifying an account as linked, recording ownership conflicts in
conflicts during dry runs as well as apply runs. Keep identity writes
conditional on --apply.
- Around line 131-132: Update the export setup around mkdirSync and
writeFileSync to restrict the exports directory to owner-only access and ensure
REPORT_PATH has mode 0600 even when the report file already exists; do not rely
on writeFileSync’s creation mode alone.
- Line 56: Update the verification guard in the account-import flow to skip
accounts unless `account.verification.status` is explicitly `"verified"`,
including when `verification` is null. Preserve the existing behavior for
verified accounts.

Review comments at @apps/backend/src/services/auth.ts:
- Around line 24-29: In apps/backend/src/services/auth.ts at lines 24-29, when
Redacted.value(bearerToken) is non-empty, catch failures from
hazelSession.fromCookie and continue to the Hazel and Clerk bearer checks;
preserve the cookie error when no bearer credential is present. In
apps/backend/src/rpc/middleware/auth.ts at lines 41-45, when the authorization
header starts with “Bearer ”, catch cookie failures and continue to the JWT,
Hazel-credential, and bot-token checks; preserve the cookie error when no bearer
credential is present.

Review comments at @apps/backend/src/services/hazel-auth.ts:
- Around line 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

`AccessToken.SigningKey` fields.

beta.38 runs persistence initialization on the invoking request's SQL
connection, so the dedicated-connection fallback for startup schema
checks on Workers is gone. Crypto uses Portable.layerWithoutKdf.
Effect 4.0.4 makes Crypto.randomUUIDv4 a function.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The Foldkit app now signs in through @yielded/auth on the API:
- /sign-in and /sign-up offer GitHub, Google and passkeys
- /auth/register lets a first-time user pick their name
- /auth/continue finishes sign-in after the callback links an account by email
- the page sign-in started from is remembered across the OAuth round trip

Requests to the API authenticate with the HttpOnly session cookie. The Electric
proxy and Rivet actors get a short-lived access token from POST /auth/token.

Organization creation, invitations and profile editing still call clerk-js and
move to Hazel RPCs next.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Both now verify the ES256 access token from POST /auth/token against the
API's JWKS, instead of a Clerk JWT. The token's subject is the Hazel user
id, so the proxy no longer looks users up by Clerk id. When the key set
can't be fetched, the proxy returns 503 so clients retry.

The deploy sets API_BASE_URL for both. A plain-HTTP dev API needs the
public key set inline in AUTH_ACCESS_TOKEN_JWKS, which generate-keys now
prints.

Maple review

🔴 Confidence 2/10 · do not merge
The post-sign-in return target is a confirmed open redirect (ran it in node); every reviewed file was read, but the web regression paths have no test.
quality 53/100 · 1 critical · 2 warnings · 1 note · tests partial · risk high · 1/3 new units observable

Adds Hazel sign-in on @yielded/auth (backend routes, session middleware, Postgres storage, proxy and actor token verification, web-foldkit pages), inert until AUTH_GITHUB_CLIENT_ID is set. Not safe to merge: the post-sign-in return target passes validation yet navigates off-origin. The open Warehouse/Mcp errors are bundle-frame attributions from other Maple services, untouched here.

  • Backend serves /auth/*, POST /auth/token and /.well-known/jwks.json, inert until AUTH_GITHUB_CLIENT_ID is set
  • RPC and HttpApi middleware resolve the Hazel session cookie or bearer credential before Clerk
  • Electric proxy and actors verify Hazel ES256 access tokens against the API's JWKS
  • web-foldkit replaces Clerk's sign-in with Hazel OAuth, passkey and register pages

Findings

🔴 Critical · F1 · safeReturnTo accepts /\t/evil.example, an off-origin post-sign-in navigation

security · apps/web-foldkit/src/auth/return-to.ts:12-15

The check only rejects a literal // or /\ prefix, but the URL parser strips tab/CR/LF before resolving, so /&#92;t/evil.example passes and new URL("/\t/evil.example", "https://app.hazel.sh/") is https://evil.example/ (verified with node). ?redirect_url=%2F%09%2Fevil.example on /sign-in reaches sign-in/update.ts:15 → rememberReturnTo → root/index.ts:33 targetOf and flows.ts:38 load(remembered ??

🟠 Warning · F2 · readSession retries permanent failures forever, so the app never leaves the loader

correctness · apps/web-foldkit/src/app/auth.ts:23

Effect.retry(retryUnavailable) has no while, so it retries every failure, not only an unreachable API as the comment at line 11 claims. When getSession returns a 500 or a payload that fails decoding, Message.ChangedAuth never fires, Effect.orDie is never reached, and app/view.ts:157 keeps rendering appLoader on every protected route: the user gets an eternal spinner with no route to sign-in, and Effect.tapError logs one line per retry. Bound the retry budget and fall back to "SignedOut" (or retry only the transport failure) so the sign-in page can render.

Give the retry a finite budget (`Effect.retry({ schedule: retryUnavailable, times: 10 })`) and `Effect.orElseSucceed(() => "SignedOut" as const)` so a persistently failing session check lands on sign-in instead of the loader.

This branch only logs and tags the span, while the 401 branch at handler.ts:134 increments proxyAuthFailures with auth_type: "user".

`safeReturnTo` accepts `/\t/evil.example`, an off-origin post-sign-in navigation
The check only rejects a literal `//` or `/\` prefix, but the URL parser strips tab/CR/LF before resolving, so `/&#92;t/evil.example` passes and `new URL("/\t/evil.example", "https://app.hazel.sh/")` is `https://evil.example/` (verified with node). `?redirect_url=%2F%09%2Fevil.example` on `/sign-in` reaches `sign-in/update.ts:15` → `rememberReturnTo` → `root/index.ts:33` `targetOf` and `flows.ts:38` `load(remembered ?? "/")`, so a just-signed-in user is navigated to the attacker's host with a live session. Validate by parsing the value against a fixed origin and require the same origin.

Add tests that reject an expired token and a token with the wrong audience.

The tests cover the wrong issuer and the wrong key. They do not cover exp or aud. Both checks are central to the security contract of the verifier. Mint expired tokens with a fixed clock, for example through TestClock or a provided DateTime source. Also cover a token with another aud.

Organizations
- organization.create no longer creates a Clerk organization
- the web app creates workspaces with its own form, in onboarding and the
  empty organization picker, instead of Clerk's widget

Invitations
- new invitation.* RPCs: create, list, revoke, a public preview, and accept
- stored in a new organization_invitations table; the emailed link carries a
  random token and only its SHA-256 hash is stored
- accepting requires the signed-in email to match the invited address
- emails go out through a Cloudflare Email Sending binding on the api Worker;
  on Bun, and without the binding, the link is logged
- /invite/:token is the accept page; settings, the invite modal and
  onboarding now use the RPCs

Profiles
- user.update now takes firstName, lastName and avatarUrl
- the profile page and onboarding save names through user.update and upload
  avatars to our storage

The web app no longer references clerk-js.

Maple review

🔴 Confidence 2/10 · do not merge
The invite batch path and the changed foldkit settings/onboarding pages decide the number; F1-F4 are still live at this head.
quality 43/100 · 1 critical · 3 warnings · 1 note · tests partial · risk medium · 3/3 new units observable · 26 files not read

Moves organizations, invitations and profiles off Clerk onto Hazel's own auth, adding the invitation.* RPCs, invite emails and session-aware middleware. Backend wiring is sound; the new invite modal batches one invitation.create per role, so a single malformed address loses every other invite in that batch. Findings F1-F4 are still unfixed, and the open issues in packages/auth/src/yielded/tables.ts and page/registry.ts are untouched. The deleted Clerk pages/mounts, the invite page group and the onboarding/select-organization tests were left unread individually.

  • invitation.create|list|revoke|preview|accept RPCs backed by organization_invitations
  • Org creation and profile/invite flows no longer call Clerk
  • RPC and HttpApi middleware accept the Hazel session cookie and credential
  • Invite emails go out via the Worker EMAIL binding, logged on Bun

Findings

🟠 Warning · F5 · One malformed address fails every invite in its role batch

correctness · apps/web-foldkit/src/data/invitations.ts:29

sendInvitations sends all addresses of a role in one invitation.create, and the payload schema is Schema.Array(Email) with a format pattern (packages/domain/src/rpc/invitations.ts:13), while the modal only drops rows whose email is empty after trim (overlay/modal/email-invite.ts:77). Typing ada@example next to two valid colleagues makes the whole call fail validation, so Effect.orElseSucceed reports all of them as failures and none are invited — the per-address call this replaced invited the rest. Validate each address before batching, or drop only the malformed rows.

Filter `emails` through the same `Email` check in `sendInvitations` and count the dropped addresses in `errorCount`, instead of letting one bad address fail the whole role's call.

Comment thread apps/web-foldkit/src/data/invitations.ts
Ports the desktop-only parts of the old app to Foldkit:
- macOS titlebar room in the dock and sidebar headers
- the app menu: Settings, Check for Updates, New Channel, Invite
- update checks at start and every 6 hours, a sticky "Install & Restart"
  toast, and an App Updates section in desktop settings
- the Desktop entry in My Settings, desktop only
- native notification setup at start

Toasts can now carry an action button that reports back to the root.

Tauri now bundles apps/web-foldkit (dev server on :3100). A shared
production-env script feeds both the web deploy and the desktop build, and
keeps any VITE_* values CI sets.

Maple review

🔴 Confidence 2/10 · do not merge
The desktop update flow is small and pinned by updates.test.ts and desktop.test.ts; three earlier findings I re-read are still unfixed at this head.
quality 51/100 · 1 critical · 2 warnings · 2 notes · tests partial · risk medium

Adds the desktop app-update flow to web-foldkit (check/install state, sticky action toast, Desktop settings page, macOS titlebar chrome) and points the Tauri build at web-foldkit instead of apps/web. The changed files are safe to merge; the Clerk-to-Hazel auth hunks are unchanged since the earlier pass. The open error issues named in the kickoff sit in other services' bundles (packages/auth/src/yielded/tables.ts, page/registry.ts) and no hunk here touches them.

  • Updates model/stream drives check, download-and-install and relaunch, with the update toast's Install & Restart action
  • MySettingsDesktop page and the desktop-only nav item, with a version read from Tauri
  • Tauri build now bundles web-foldkit (frontendDist, devUrl 3100, production-env.sh)
  • web-foldkit boot drops clerk-js and runs initTauri() instead

Before merge

Findings

🔵 Note · F6 · The Downloading toast pushed after Install & Restart lands on a toast already marked removed

correctness · apps/web-foldkit/src/main.ts:176-184

Clicking the action runs Toast.update's ClickedAction, which marks that toast removed but keeps it in the array for ~200ms (ui/toast.ts:237), and Toasts.push reuses the same tauri-update id, so the Downloading toast is written into the removed item (ui/toast.ts:345 never clears isRemoved) and is deleted before it renders. The user clicks Install and sees no download state until the first progress event arrives (a fast download shows none).

Use a fresh toast id for each update state, or have `Toasts.push` reset `isRemoved` on the toast it updates.

The desktop app now signs in with @yielded/auth BrowserLogin instead of Clerk.

- The app opens /auth/desktop in the system browser. There the signed-in
  browser confirms the account, signing in first if needed.
- The browser hands back through com.hazel.app://auth/callback. The app
  exchanges that for its own session, which is kept in the OS keychain and
  sent as a bearer on API calls.

API:
- browser-login and /auth/native/* routes
- one new table, yielded_browser_login (sql/2026-10-13-desktop-sign-in.sql)
- POST /auth/token also accepts the desktop session as a bearer

Shared client:
- @hazel/auth/desktop: a vault over any record store, plus sign-in,
  session and sign-out calls

Tauri:
- keychain-backed auth_vault_* commands
- single-instance forwarding of deep links on Windows and Linux
- removes the unused localhost OAuth callback server

Tested end to end against Postgres: a browser authorizes, the desktop
client exchanges, its bearer verifies, and signing out ends only the
desktop session.

Maple review

🔴 Confidence 2/10 · do not merge
Auth, tenancy and handoff code with a critical cookie-CSRF gap; the Tauri Rust diff and two web-foldkit file groups went unread.
quality 14/100 · 2 criticals · 3 warnings · 3 notes · tests partial · risk high · 0/2 new units observable

Backend and web work for Hazel sign-in on @yielded/auth, with the routes unmounted while AUTH_GITHUB_CLIENT_ID is unset. Not safe to merge as it stands: the browser token exchange omits the CSRF header /auth/token requires. The open warehouse/MCP errors attributed to packages/auth/src/yielded/tables.ts and apps/web-foldkit/src/page/registry.ts are unrelated bundle frames this change neither touches nor fixes; F1, F2, F4, F5 and F6 are all still open (F6 unread). I did not read the Tauri Rust diff, apps/web-foldkit/src/page/auth/sign-in/*, or apps/web-foldkit/src/route.ts; two review groups failed.

  • exchange mints the Electric/actor access token from the session cookie
  • readSession and signOut branch on isDesktop
  • Desktop sign-in waits on a com.hazel.app://auth/callback deep link
  • Invitations move to invitation.* RPC by role

Before merge

Findings

🔴 Critical · F7 · exchange posts the session cookie without the required x-effect-auth-csrf header

correctness · apps/web/src/lib/access-token.ts:34

/auth/token is mounted under http.middleware (apps/backend/src/services/hazel-auth.ts:179), whose cookie-credentialed POSTs require x-effect-auth-csrf: 1 — the backend's own test sets it on exactly this route (apps/backend/src/services/hazel-auth.test.ts:204, used at :260) and the desktop routes mirror it (packages/auth/src/yielded/desktop-login.ts:27). This raw fetch sends only credentials: "include", so in a browser the exchange is rejected, getAccessToken returns null for the life of the tab, and every Electric and Rivet request 401s while the desktop bearer branch keeps working.

Send the header on the cookie branch (`credentials: "include", headers: { "x-effect-auth-csrf": "1" }`).
🟠 Warning · F8 · open consumes a stale queued callback from an earlier attempt

correctness · apps/web-foldkit/src/platform/desktop-auth.ts:87

A callback that arrives after an attempt ended (timeout at line 99, or the finalizer at 94-97 clearing receive) is pushed onto queued with no timestamp and no attempt id, and the next open unconditionally queued.shift()s it before opening the browser. That attempt therefore spends its code on the previous attempt's callback and reports a failure while its own callback queues behind it — repeating on every retry and on cold start.

Record the arrival time and attempt on each queued entry, drop entries older than the attempt lifetime before shifting, and never resolve a new attempt from an entry queued before it started.
🔵 Note · F9 · 2026-10-13-desktop-sign-in.sql cannot be re-applied

correctness · packages/db/sql/2026-10-13-desktop-sign-in.sql:11

The file header and the runbook (infra/hazel-auth-rollout.md) tell operators to apply it with psql -v ON_ERROR_STOP=1 -f, but CREATE TABLE and ADD CONSTRAINT have no IF NOT EXISTS, so a second run on a stage that already has the table aborts the transaction and reports a failure that is not a failure — the same PR's 2026-10-11-hazel-auth.sql guards its columns this way.

Use `CREATE TABLE IF NOT EXISTS` and declare the primary key inline, or guard the `ADD CONSTRAINT` the way the 2026-10-11 migration guards its `ADD COLUMN`.

Maple review

🟡 Confidence 6/10 · needs attention
Auth/tenancy and migration code carries high risk, and the new auth routes' span coverage was not verified; earlier-review fixes all hold at this head.
quality 88/100 · 1 warning · 1 note · tests covered · risk high · 11 files not read

Adds Hazel's own sign-in on @yielded/auth (routes, session resolution, Clerk-identity import, Postgres schema) alongside Clerk, gated on AUTH_GITHUB_CLIENT_ID. Every earlier-review defect holds fixed at this head; two small new defects remain. The listed open error issues (Warehouse*, McpQuery, Vcs*, IntegrationsUpstream, GithubAppError) come from other services and only share bundler-mapped paths with packages/auth/src/yielded/tables.ts and web-foldkit/src/page/registry.ts — this change does not touch them. The new test files and the deploy workflow were not read.

  • HazelSession resolves a session cookie (trusted Origin) or bearer, then falls back to Clerk
  • New /auth/*, POST /auth/token and /.well-known/jwks.json behind AUTH_GITHUB_CLIENT_ID
  • Auth storage runs on the request's own lazily-opened Postgres connection
  • import-clerk-identities.ts links existing users by verified email

Findings

🟠 Warning · F10 · slugify can end a long workspace slug in -, which the form then rejects

correctness · apps/web-foldkit/src/page/create-workspace.ts:49-56

.replace(/^-+|-+$/g, "") runs before .slice(0, 48), so a name whose hyphenated form is longer than 48 characters and has a hyphen at index 48 (a…a b → a…a-) auto-fills a slug that SLUG_PATTERN rejects, and SubmittedWorkspace returns without dispatching CreateWorkspace, showing "Use at least 3 lowercase letters, numbers or hyphens" for a slug the user never typed.

Strip trailing hyphens after truncating: `.replace(/[^a-z0-9]+/g, "-").slice(0, 48).replace(/-+$/g, "")`, and add a test for a name at the slice boundary.
🔵 Note · F11 · Hand-written DDL names the PK yielded_browser_login_namespace_attempt_id_pk, the migration says yielded_browser_login_pkey

maintainability · packages/db/sql/2026-10-13-desktop-sign-in.sql:17

The runbook applies this file to prd before db:migrate, so CREATE TABLE IF NOT EXISTS "yielded_browser_login" in packages/db/migrations/20261013222300_hazel_auth/migration.sql is skipped and the live table keeps this PK name, which the snapshot records as yielded_browser_login_pkey — the tracked schema then never matches the database db:generate/db:verify diff against.

Rename the constraint here to `"yielded_browser_login_pkey"`, or regenerate the migration from `packages/db/src/tables/auth.ts` so both artifacts name it the same.

`slugify` can end a long workspace slug in `-`, which the form then rejects
`.replace(/^-+|-+$/g, "")` runs before `.slice(0, 48)`, so a name whose hyphenated form is longer than 48 characters and has a hyphen at index 48 (`a…a b` → `a…a-`) auto-fills a slug that `SLUG_PATTERN` rejects, and `SubmittedWorkspace` returns without dispatching `CreateWorkspace`, showing "Use at least 3 lowercase letters, numbers or hyphens" for a slug the user never typed.

Fixed since the last review

  • ✅ F1 · safeReturnTo accepts /\\t/evil.example, an off-origin post-sign-in navigation
  • ✅ F2 · readSession retries permanent failures forever, so the app never leaves the loader
  • ✅ F4 · New 503 auth-unavailable branch does not increment proxyAuthFailures
  • ✅ F5 · One malformed address fails every invite in its role batch
  • ✅ F6 · The Downloading toast pushed after Install & Restart lands on a toast already marked removed
  • ✅ F7 · exchange posts the session cookie without the required x-effect-auth-csrf header
  • ✅ F8 · open consumes a stale queued callback from an earlier attempt
  • ✅ F9 · 2026-10-13-desktop-sign-in.sql cannot be re-applied
