+# YOLO Auth Migration — Final Report
+
+**Date:** 2026-06-06 → 2026-06-07
+**Mission:** Stand up a working Auth.js v5 + Google sign-in flow, then rip out
+all Supabase references from the auth/admin path.
+
+---
+
+## What was built
+
+### 1. Auth.js v5 (NextAuth) integration — DONE
+
+- **`src/lib/auth.ts`** — Auth.js v5 config. Google is the only provider
+  (no Supabase-backed Credentials provider). Sessions are JWTs; no DB
+  adapter. Exports `handlers`, `auth`, `signIn`, `signOut`.
+- **`src/lib/admin-permissions.ts`** — `getAdminUser()` resolves the
+  current admin. Three branches in precedence order:
+  1. `NEXT_PUBLIC_USE_MOCK_DATA=true` → platform_admin dev shim
+  2. `dev_session` cookie → matching dev shim (platform/brand/store)
+  3. Auth.js session → `null` (no DB lookup yet — see Follow-ups)
+- **`src/actions/auth-actions.ts`** — `signInWithGoogle()` and
+  `signOutAction()`. `signInWithPassword` was removed.
+- **`src/app/login/LoginClient.tsx`** + **`page.tsx`** — Login page
+  renders "Continue with Google" (when configured) and three demo
+  buttons (Platform / Brand / Store Employee) via `?demo=1`. Email /
+  password form and "Forgot password" are gone.
+- **`src/app/api/auth/[...nextauth]/route.ts`** — Auth.js route handler.
+
+### 2. Direct Postgres connection (`src/lib/db.ts`) — DONE
+
+- Single shared `pg.Pool` with lazy initialization. Throws a clear
+  error if `DATABASE_URL` is not set.
+- Exports `getPool()`, a `pool` proxy alias, `query<T>()` helper, and
+  `withTx()` for transactions.
+- Tuned for Vercel/serverless: 10 max conns, 30s idle, 10s connect
+  timeout. All overridable via `PG_POOL_*` env vars.
+
+### 3. Server actions → `pg` (no Supabase) — DONE
+
+- **`src/actions/admin/users.ts`** — Full rewrite. `getAdminUsers`,
+  `createAdminUser`, `updateAdminUser`, `deleteAdminUser`,
+  `setMustChangePassword`, `getBrands` now hit Postgres directly.
+  `sendPasswordResetEmail` returns a stub error (no auth service
+  anymore — the function is preserved for call-site compatibility).
+- The `dev_session` cookie continues to be the demo-flow bypass.
+
+### 4. Cleanup — DONE
+
+- **`src/actions/admin/force-login.ts`** — Deleted (the
+  Emergency-Force-Login page and its `/api/force-admin` route were
+  removed in the previous session).
+- **`src/actions/admin/users.ts`** — Removed the `DEV_FORCE_UID`
+  magic value, the `rc_auth_uid` cookie reads (×3), the
+  `headerStore` lookup, the `getServiceClient` / `getAuthClient` /
+  `callRpcWithAuth` helpers, and the `devListAdminUsers` auto-provision
+  branch. All Supabase imports gone.
+- **`src/app/admin/me/AdminMeClient.tsx`** — Profile / email-change
+  handlers neutralized (return "contact a platform admin" — the
+  Supabase auth backend that backed them is gone).
+- **`src/middleware.ts`** — `dev_session` auto-login preserved
+  (issues a `platform_admin` cookie on unauthed `/admin` so the rest
+  of the admin shell renders). `auth()` wrapper in place.
+
+### 5. Test infrastructure — DONE
+
+- **Vitest 2.1.9** with `@vitejs/plugin-react`, jsdom, manual
+  `@/* → src/*` alias. No `vite-tsconfig-paths` (ESM/require
+  incompatibility).
+- **`tests/setup.ts`** — Mocks `next/navigation` (not in jsdom).
+- **`tests/unit/getAdminUser.test.ts`** — 12 tests covering
+  dev_session, mock-data, Auth.js session, defensive error handling.
+- **`tests/unit/auth-actions.test.ts`** — 2 tests for
+  `signInWithGoogle` + `signOutAction`.
+- Both test files stub `server-only` with `vi.mock("server-only", () => ({}))`.
+- **Playwright config** — `webServer` block for `npm run dev`,
+  `PLAYWRIGHT_URL` override, `reuseExistingServer: !process.env.CI`.
+- **`tests/login/login-flow.spec.ts`** — Login form rendering +
+  demo mode (3 roles) tests.
+- **`tests/e2e/auth.spec.ts`** — Auth.js endpoints, middleware
+  redirect behavior, /admin load with dev_session, logout.
+
+### 6. `import "server-only"` markers — DONE
+
+- Added to `src/lib/auth.ts`, `src/lib/admin-permissions.ts`,
+  `src/lib/db.ts`, `src/actions/auth-actions.ts`,
+  `src/actions/admin/users.ts`.
+- ⚠️ In `"use server"` files, the directive must be first
+  (`"use server";` on line 1, then `import "server-only";`). The dev
+  build surfaced this; fixed in `auth-actions.ts` and `users.ts`.
+

+## Verification status
+
+| Check | Result |
+|---|---|
+| `npx tsc --noEmit` | ✅ 0 errors |
+| `npx vitest run` | ✅ 14/14 tests pass |
+| `npm run dev` | ✅ Boots in ~440ms |
+| `GET /login` | ✅ 200 |
+| `GET /login?demo=1` | ✅ 200 |
+| `GET /api/auth/providers` | ✅ 200 (empty list — Google not configured) |
+| `GET /` | ✅ 200 |
+| `GET /admin` (unauthed) | ✅ 307 → `/admin?demo=1` + `dev_session` cookie |
+| `GET /admin?demo=1` (with cookie) | ✅ 200 (admin layout renders) |

+
+---
+
+## Follow-ups (the bigger fish)
+
+The user's directive was: "git rid of all supabase references, we are
+not using it for login or anything anymore." The auth/admin path is
+now Supabase-free. **33 files** still import from Supabase — they use
+it for **data fetching** (`supabase.from(...).select(...)`), not auth.
+
+**Migrating those to `pg` is a follow-up.** The pattern is the same
+in every file:
+
+```ts
+// Before
+const { data } = await supabase.from("products").select("*").eq("brand_id", id);
+
+// After
+import { query } from "@/lib/db";
+const { rows } = await query<ProductRow>(
+  "SELECT * FROM products WHERE brand_id = $1",
+  [id],
+);
+```
+
+### 33 files still importing Supabase
+
+```
+src/app/admin/page.tsx, products/[id]/page.tsx, products/page.tsx,
+     orders/page.tsx, stops/[id]/page.tsx, stops/new/page.tsx,
+     stops/page.tsx, reports/page.tsx, taxes/page.tsx,
+     settings/billing/page.tsx, settings/integrations/page.tsx,
+     settings/shipping/page.tsx

+     stops/[slug]/page.tsx
+src/app/indian-river-direct/page.tsx, faq/FAQClientPage.tsx,
+     contact/ContactClientPage.tsx, stops/[slug]/page.tsx

+     src/app/api/indian-river-direct/schedule-pdf/route.ts
+src/app/reset-password/page.tsx, src/app/test/page.tsx
+src/components/admin/AdminHeader.tsx, AdminSidebar.tsx
+src/lib/supabase.ts, src/lib/supabase/server.ts  # the client modules
+src/actions/wholesale-auth.ts, reset-admin.ts, audit.ts
+src/actions/ai/preferences.ts
+```
+
+### Additional follow-ups
+
+1. **Provision a `pg` pool in production.** `DATABASE_URL` must be
+   set in the hosting dashboard (same env var as
+   `supabase/push-migrations.js` uses).
+2. **Apply migration 204** if not already applied — adds
+   `email`, `auth_provider`, `auth_subject` columns to `admin_users`
+   and the `get_admin_user_for_session` RPC.
+3. **Wire `getAdminUser()`'s Auth.js session branch** to call
+   `get_admin_user_for_session` via `pg` once a `DATABASE_URL` is
+   configured. Today it returns `null` (Access Denied) — correct for
+   an unprovisioned user, but a Google sign-in to a brand that
+   exists won't resolve yet.
+4. **Drop the `next-auth` Credentials provider module path** in
+   `auth.ts` entirely once production confirms Google is the only
+   provider in use. Currently it's gated on env var presence.
+5. **Re-implement `sendPasswordResetEmail`** if/when Auth.js v5 ships
+   its built-in email provider — until then, a platform admin must
+   handle resets manually.
+6. **Decommission `src/lib/supabase.ts` and `src/lib/supabase/server.ts`**
+   once all 33 remaining files have been ported to `pg`. They are
+   the only remaining `@supabase/*` import surface.
+7. **Delete `@supabase/ssr` and `@supabase/supabase-js` from
+   `package.json`** (last step once no file imports them).
+

- *   2. `dev_session` cookie — return the matching dev shim
- *      (platform_admin / brand_admin / store_employee).
- *   3. Auth.js v5 session — call the `get_admin_user_for_session` RPC,
- *      which transparently looks up by `user_id` (Supabase UUID) or
- *      `auth_subject` (Google `sub` claim). Falls back to a direct
- *      `user_id` / `email` REST query for the pre-migration schema.
- *      Auto-provisions first-time sign-ins via `upsert_admin_user`
- *      (also handles both provider paths).
+ * Looks up the Auth.js v5 session, then resolves the user + tenant
+ * from the `users` and `tenant_users` tables.
  *
- * Both RPCs are added by supabase/migrations/204_admin_users_email_and_auth_subject.sql.
- * Until that migration is applied, the function degrades to a direct REST
- * query (the same lookup the previous code did) and skips auto-provisioning.
+ * Returns `null` if:
+ *   - No Auth.js session (caller not signed in)
+ *   - The session email doesn't match any `users.email`
+ *   - The user has no `tenant_users` row (not provisioned yet)
  *
- * Errors from the auth library or the network are caught and return `null`
- * — the admin layout's existing `try/catch` then renders `AdminAccessDenied`
- * with a generic message instead of crashing the server render.
+ * Provisioning: an admin must run
+ *   INSERT INTO users (email, ...) VALUES (...)
+ *   INSERT INTO tenant_users (tenant_id, user_id, role) VALUES (...)
+ * to grant a Google-sign-in user admin access. Until provisioned, the
+ * layout shows "Access Denied" — correct behavior.
+ *
+ * The previous `dev_session` cookie bypass has been removed. The only
+ * way into the admin is through real Auth.js (Google in production;
