Session middleware resolves the token to a `User` record via the `sessions` table, then resolves the user's `Member` record for group-scoped routes. Legacy anonymous sessions (pre-auth members with `sessionToken` on the `members` table) continue to work via a fallback path. Permission checks (role enforcement) happen in route handlers, not the UI. --- @@ -273,7 +334,7 @@ Three roles, enforced server-side: - Manage group settings (name, expiration, invite link regeneration) - Promote members to admin, demote admins back to member - Cannot be removed from the group -- **Ownership recovery:** If the owner loses their session token (new device, cleared storage), ownership automatically transfers to the first available admin, or if no admins exist, to the earliest-joined active member — triggered lazily the next time an owner-level action is attempted (not immediately, to avoid unnecessary promotions). There is no manual claim action; the transfer happens automatically and silently. The transfer is recorded as a group activity feed entry (e.g., "Alice is now the group owner") so members are aware of the change without a separate notification system. +- **Ownership recovery:** With Google OAuth, ownership is tied to the user's account (not a browser session), so ownership loss from clearing browser data is no longer an issue.

Implemented via a `left_at` timestamp on the Member table; UI filters them from the active view but includes them in balance calculations. -- **Session token storage:** httpOnly cookie — not localStorage. httpOnly cookies are inaccessible to JavaScript (XSS-safe); localStorage is not. CSRF risk is acceptable given the no-auth, low-stakes context. +- **Authentication:** Google OAuth via raw fetch to Google token endpoint (no `@fastify/oauth2` dependency). Chosen over email/password (no password management burden), magic links (requires email infrastructure), and anonymous-only (too limited for multi-group support). CSRF protection via state parameter in OAuth flow. +- **Session token storage:** httpOnly cookie — not localStorage. httpOnly cookies are inaccessible to JavaScript (XSS-safe); localStorage is not. +- **Dual-path session resolution:** Backward-compatible design supporting both new authenticated sessions (via `sessions` table) and legacy anonymous sessions (via `members.sessionToken`). No forced migration — anonymous members remain functional alongside authenticated members. - **Group expiration:** Activity-based (90 days from last expense), not creation-based. Simpler, better product behavior, removes the need for a "never expires" settings toggle. - **Financial arithmetic:** Integer cents internally, stored as `DECIMAL(10,2)` in PostgreSQL. Never `FLOAT` — avoids rounding errors for financial data. - **Abuse mitigation:** Simple caps for v1 — max 50 members per group, $10,000 per individual expense, 30 expense submissions per hour per member. No reporting UI — group owner can remove bad actors. diff --git a/infra/main.tf b/infra/main.tf index 639f379..49ce5da 100644 --- a/infra/main.tf +++ b/infra/main.tf @@ -28,12 +28,15 @@ locals { }
