 ## Current Work (newest first)
 
+- [2026-02-20T10:04:27Z] progress: extracted IPC bridge composition from `src/main.ts` into `src/main/runtime/ipc-runtime-handlers.ts`; `main.ts` now builds `handleMpvCommandFromIpc` and `runSubsyncManualFromIpc` via one `createIpcRuntimeHandlers(...)` factory.
+- [2026-02-20T10:04:27Z] progress: added `src/main/runtime/ipc-runtime-handlers.test.ts` for composed IPC handler wiring behavior.
+- [2026-02-20T10:04:27Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + focused suites pass for `ipc-runtime-handlers*`, `ipc-bridge-actions*`, `cli-command-context*`, `yomitan-extension-runtime*`, and `overlay-visibility-runtime*` (11/11).
+- [2026-02-20T10:04:27Z] scope: staging only `src/main.ts`, new IPC runtime module/tests, and subagent bookkeeping.
 - [2026-02-20T10:02:30Z] progress: extracted overlay visibility action composition from `src/main.ts` into new runtime module `src/main/runtime/overlay-visibility-runtime.ts`; `main.ts` now consumes a single `createOverlayVisibilityRuntime(...)` factory for set/toggle overlay handlers.
 - [2026-02-20T10:02:30Z] progress: added `src/main/runtime/overlay-visibility-runtime.test.ts` to lock behavior of composed set/toggle/setOverlay/toggleOverlay wiring.
 - [2026-02-20T10:02:30Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + focused suites pass for `overlay-visibility-runtime*`, `overlay-visibility-actions*`, `overlay-runtime-bootstrap*`, `overlay-window-layout*`, and `cli-command-context*` (16/16).
