 - 2026-03-10 — Mobile workstream moved from draft-only planning into initial implementation.
 - `learning_ai_notes/mobile/` was scaffolded from scratch with Expo + TypeScript.
 - Root app config now exists: `package.json`, `app.json`, `tsconfig.json`, `index.ts`, `babel.config.js`.
-- Expo Router shell now exists with auth entry, tab layout, home/recent notes, search, quick capture, inbox placeholder, and note detail routes.
+- Expo Router shell now exists with auth entry, tab layout, home/recent notes, search, quick capture, inbox, and note detail routes.
 - Shared mobile bootstrap files now exist for:
   - `@bytelyst/auth-client`
   - `@bytelyst/platform-client`
   - `@bytelyst/offline-queue`
   - token-based theme wiring via `@bytelyst/design-tokens/tokens.json`
 - Zustand-backed auth, notes, and workspace stores were added for first-pass mobile state management.
+- Home/search/capture now use active workspace context for more useful mobile browsing.
+- Note detail now supports lightweight local editing plus basic artifact metadata viewing.
+- Inbox now supports simple approval/reject flows and a lightweight activity feed.
 - Mobile currently uses provisional product config and fallback note/workspace data until product identity and backend contract details are finalized.
 
 # Open Questions
 
-- What is the final canonical `productId` for ByteLyst Agentic Notes?
-- What is the final product backend port for the notes service?
+- Should the current provisional bootstrap values (`productId: bytelyst-notes`, backend port `4016`) now be treated as final?
 - What are the final iOS bundle identifier, Android package name, and URL scheme/domain values?
 - Should mobile notes access go directly to the product backend for note CRUD while auth remains on `platform-service`?
-- Is approvals inbox definitely in MVP scope, or should it remain a deferred Phase M2/M3 item?
+- Should the current local approval/activity model map directly to backend `note-agent-actions`, or stay as a mobile-specific condensed surface?
