 ## Current Work (newest first)
 
+- [2026-02-20T09:59:54Z] progress: pivot batch completed: extracted Yomitan extension runtime wiring from `src/main.ts` into new module `src/main/runtime/yomitan-extension-runtime.ts` and replaced `main.ts` setup with `createYomitanExtensionRuntime(...)`.
+- [2026-02-20T09:59:54Z] progress: added regression coverage for extracted composition in `src/main/runtime/yomitan-extension-runtime.test.ts`; finalized remaining inline `build*MainDepsHandler(),` constructor sites in `src/main.ts` (count now 0).
+- [2026-02-20T09:59:54Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + targeted suites pass for `yomitan-extension-runtime*`, `yomitan-extension-loader*`, `mpv-subtitle-render-metrics*`, `overlay-window-layout*`, `mining-actions*`, `ipc-bridge-actions*`, `cli-command-context*`, `startup-warmups*` (30/30).
+- [2026-02-20T09:59:54Z] scope: staging `src/main.ts`, new Yomitan runtime module/tests, and subagent bookkeeping only; unrelated workspace deltas remain excluded.
 - [2026-02-20T09:51:57Z] progress: completed another 2-slice safe batch (10 normalized sites) by prebuilding finalized deps for stop/run Jellyfin command handlers, app lifecycle runner, initial-args handler, MPV event binding, and numeric/overlay-shortcut related setup.
 - [2026-02-20T09:51:57Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + targeted suites pass for `jellyfin-command-dispatch*`, `jellyfin-remote-session-lifecycle`, `app-lifecycle-*`, `initial-args*`, `mpv-main-event-*`, `numeric-shortcut-*`, `overlay-shortcuts-lifecycle*`, and `anki-actions` (39/39).
 - [2026-02-20T09:51:57Z] scope: committing only `src/main.ts` + subagent bookkeeping files; unrelated workspace noise still excluded.
