scaffolding hermes flow and audit logging

 # Project Template: Native Betting Study App
 
+This is the canonical working plan for the project. Use this file for progress notes, next steps, and status updates.
+
+## Current Status
+
+### Done So Far
+
+- Android was renamed from the old study app into `com.hermes.app`, with the app entry, theme, repository, media, and feature screens rewritten around the backend-backed Hermes flow.
+- Android no longer relies on the sample fixture; it boots from backend session and round data, uses `/health.server_time` for clock sync, buffers analytics, and flushes them to the backend.
+- Android localization is in place for English and Swedish, including the remaining locale toggle labels and session language display.
+- Backend now exposes `server_time` from `/health`, publishes the matching OpenAPI contract, and records audit events for session, bet, event, market, odds, and settlement actions.
+- Backend smoke coverage was added for `server_time` and audit logging.
+- iOS now follows the backend-backed flow, syncs clock from `/health`, flushes analytics, and uses localized language labels instead of hardcoded `EN` and `SV`.
+- iOS source was updated for the backend-backed session and round flow, including the real preview cue points and localized session strings.
+- Android debug build passes with `./gradlew :app:assembleDebug`.
+- Backend tests pass with `cargo test`.
+
+### Still Open
+
+- Continue through the remaining plan phases and finish any leftover localization and polish work.
+- Add iOS build validation once an Xcode project is available in `mobile/ios-app`.
+- Keep expanding tests around session, odds, settlement, and analytics behavior.
+
 ## 1. Purpose
 
 Build a native mobile prototype for iOS and Android for a research

+# Hermes Progress
+
+## Done
+
+- Android: switched the app to the Hermes package/name, backed the UI with the backend, added server clock sync, and buffered analytics flushing.
+- Android: localized the remaining language labels so the locale toggle and session language row no longer show hardcoded `EN`/`SV`.
+- Backend: added `server_time` to `/health`, added audit logging, and added smoke coverage.
+- iOS: switched the source to the backend-backed flow, added clock sync, analytics flushing, and localized the remaining language labels.
+- Verified Android with `./gradlew :app:assembleDebug`.
+- Verified backend earlier with `cargo test`.
+
+## Next
+
+1. Continue from the current plan phase and keep closing out the remaining localization and polish items.
+2. Keep Android and iOS behavior aligned with the backend contract.
+3. Add or verify iOS build coverage if an Xcode project becomes available.
+4. Continue expanding tests around session, odds, settlement, and analytics flow as the app grows.
+
+## Notes
+
+- English and Swedish are required from day one.
+- The server remains authoritative for lock time, odds acceptance, and settlement.
+- iOS build validation is still unavailable here because there is no Xcode project in `mobile/ios-app`.
