CLIENT__IDAA_and_customized_mods.md:
- Verification Flow: describe Aether proxy call, not direct browser-to-Novi fetch
- Replace old fetch() code snippet with new Aether endpoint call
- Update novi_idaa_api_key / novi_api_root_url field descriptions (server-side only now)
- Security notes: key never sent to browser; shape changes go in backend method
- Rate limit note: 12h TTL (was 5-min), add 503 auto-retry behavior
- Fix Redis cache key: idaa:novi_member:{uuid} (account_id was dropped from key)
GUIDE__AE_API_V3_for_Frontend.md §12:
- 503 frontend action: auto-retry once after 3s before api_error
- Mark migration section complete (2026-05-19); update table to show retry behavior
