 ## Session Continuity
 
 ### Last Session
 
 **Date:** 2026-03-05
-**What happened:** Quick task 11 — fixed neovim display corruption during library scan. Root cause: dev mode hardcoded slog.LevelDebug, flooding stdout with ~14 debug lines per audio file. Added resolveLogLevel() with YJ_LOG_LEVEL env var support, defaulting to Info. Added `make dev-debug` target for opt-in verbose logging.
-**Where we stopped:** Quick task 11 complete. Dev mode now defaults to Info-level logging.
-**Next action:** Test `make dev` with library scan to confirm neovim stability
+**What happened:** Quick task 12 — added favorite icon to album dropdown track rows. Added FavoritesController + classMap integration with compact sizing (18px/11px) for the dropdown context. Icon between track number and title, with stopPropagation click handler.
+**Where we stopped:** Quick task 12 complete. Album dropdown now shows per-track favorite icons.
+**Next action:** Visually verify favorite icons in album grid dropdown

+# Quick Task 12: Add Favorite Icon to Album Grid Track List Summary
+
+Per-track favorite icon in album dropdown, matching track-list pattern with compact sizing (18px width, 11px font) for the 12px dropdown context.
+
+## What Was Done
+
+### Task 1: Add favorite icon to album dropdown track rows
+**Commit:** `12a0bbc`
+
+Added FavoritesController integration to `<album-dropdown>` component:
+
+- **Imports:** Added `FavoritesController` from `@store/controllers/favorites-controller` and `classMap` from `lit/directives/class-map.js`
+- **Controller:** Added `private favCtrl = new FavoritesController(this)` alongside existing `player` controller
+- **CSS:** Added `.fav-icon` styles with compact sizing (18px width, 11px font) proportional to the dropdown's 12px track rows. Includes tertiary color default, primary on hover, accent color when favorited
+- **Template:** Inserted favorite icon `<div>` with `<wa-icon>` between track number and track title in `renderTrackRow()`. Icon uses `classMap` for dynamic `.favorited` class and `stopPropagation()` on click to prevent track selection
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Verification
+
+- `npx tsc --noEmit` — TypeScript compilation passed with zero errors
+- `lefthook` pre-commit hook (`frontend-typecheck`) passed
