+- 2026-03-10 — Mobile verification materially advanced:
+  - mobile dependencies now install successfully with corrected sibling `@bytelyst/*` package paths
+  - `npm run typecheck`, `npm run lint`, and `npm test` now pass in `learning_ai_notes/mobile/`
+  - token-backed placeholder and border colors replaced the remaining raw hardcoded mobile color fallbacks

+- Mobile dependency install now succeeds, and `npm run typecheck`, `npm run lint`, and `npm test` pass in `mobile/`.
+- Mobile now uses token-backed placeholder and border colors instead of raw hardcoded fallbacks.
 - Mobile currently uses provisional product config and fallback note/workspace data until product identity and backend contract details are finalized.

-- Dependencies for the new `mobile/` app have not yet been installed, so build/typecheck/runtime verification is still pending.
 - `@bytelyst/react-native-platform-sdk` is referenced as a planned shared dependency, but the current workspace package does not appear ready for direct runtime consumption in this new app yet.
 - Product identity and backend contract details remain provisional in the planning docs, so mobile config values are placeholders.
