+## Deviations from Plan
+
+None. All tasks completed as specified. Intended non-updates (rotate_refresh_token, api/client.js) confirmed as correct.

+---
+
+## Human Checkpoint: PASSED
+
+User confirmed:
+- "Stay signed in for 30 days" checkbox visible on login page
+- Cookie Max-Age verified in DevTools → Network → POST /api/auth/login → Response Headers → set-cookie

+
+## Phase 7.3 Complete
+
+All 3 plans shipped:
+- **Plan 01 (Wave 0):** 9 xfail TDD stubs scaffolded
+- **Plan 02 (Wave 1):** ES256 JWT signing at all 4 sites + startup rotation hook + operator wiring
+- **Plan 03 (Wave 2):** remember_me TTL split + cookie Max-Age + frontend checkbox
+
+Phase outcome: ES256 asymmetric JWT signing live; default session 16h; opt-in 30-day sessions; startup bulk-revocation on algorithm change; all 9 ES256/remember-me tests green.
