 - [2026-02-20T09:30:02Z] progress: applied 5-block safe normalization in `main.ts` by prebuilding deps handlers for global shortcuts (`getConfiguredShortcuts`, `registerGlobalShortcuts`, `refreshGlobalAndOverlayShortcuts`) and MPV logging/OSD (`appendToMpvLog`, `showMpvOsd`).
 - [2026-02-20T09:30:02Z] progress: earlier in this batch also extracted `jellyfin-playback-launch-main-deps`, `immersion-startup-main-deps`, `numeric-shortcut-runtime-main-deps`, and `mpv-subtitle-render-metrics-main-deps`; extended `config-hot-reload-main-deps` with watcher/message builders.
 - [2026-02-20T09:30:02Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + targeted suites pass for `global-shortcuts*`, `mpv-osd-log*`, `jellyfin-playback-launch*`, `immersion-startup*`, `config-hot-reload-main-deps*`, `mpv-subtitle-render-metrics*`, `numeric-shortcut-runtime-main-deps*`, `initial-args*`.
+- [2026-02-20T09:32:11Z] progress: completed 5-block safe normalization in `main.ts`: prebuilt deps handlers for CLI context main deps, MPV main-event bind deps, MPV runtime service factory deps, MeCab initializer deps, and subtitle dictionary prewarm deps.
