## The problem Three pieces of user data (pro status, avatar metadata, profile picture) were being fetched from four different places: `initializeAuth` on mount, the `SIGNED_IN` handler, the `TOKEN_REFRESHED` handler, and the post-upgrade path. On a fresh login the first two both see a session, so everything got fetched twice. It didn't stop after login either — Supabase re-fires `SIGNED_IN` on token refresh and tab-visibility wakeups, so a refresh that emitted both events cost around 7 Supabase reads. ## The fix All four call sites now go through one `loadUserData(session)` that is idempotent per identity. The guard key is `user.id` + `is_anonymous`: - not the access token, which changes on every refresh and would defeat the guard entirely - the anonymous flag matters because a guest to authenticated upgrade keeps the same user id, and that is the one case where the data genuinely does need reloading **Per login: 6 fetches to 3. A repeat `SIGNED_IN` or `TOKEN_REFRESHED` fetches nothing.** The tests count real calls rather than asserting on shape. ## Two behaviour changes worth naming - `initializeAuth` now awaits the full load, so the initial spinner also waits on the profile-picture URL. Net login is still faster, since an entire duplicate pass is gone. - A tab-wake `SIGNED_IN` no longer revalidates entitlements. That revalidation was accidental rather than designed — `refreshProStatus()` is the intended path, and post-checkout is already handled by `CheckoutContext`. ## Scope Supabase-origin traffic only. This does not touch the ~20 authenticated requests hitting `SupabaseAuthenticationFilter`, because those go to the Stirling backend rather than the hosted Supabase project. That is a separate problem and is unmeasured, so it needs measuring before anything is optimised. Remaining items (a double `/api/v1/team/my` fetch, an effect keyed on `[user]` identity in `FolderContext`, the `portalAccess` spinner flash, and caching the auth filter's per-request Postgres round-trips) are tracked separately. ## Verification ``` npx tsc --noEmit --project editor/src/saas/tsconfig.json # exit 0 npx eslint --max-warnings=0 editor/src/saas/auth # exit 0 npx prettier --check editor/src/saas/auth/ # clean npx vitest run --project saas # 75 passed (20 files) ```
