 ## Current Work (newest first)
 
+- [2026-02-20T11:06:51Z] progress: extracted overlay bootstrap composition from `src/main.ts` into `src/main/runtime/overlay-runtime-bootstrap-handlers.ts`; `main.ts` now creates `initializeOverlayRuntime` through `createOverlayRuntimeBootstrapHandlers(...)`.
+- [2026-02-20T11:06:51Z] progress: added `src/main/runtime/overlay-runtime-bootstrap-handlers.test.ts` for composed bootstrap behavior.
+- [2026-02-20T11:06:51Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + focused suites pass for `overlay-runtime-bootstrap-handlers*`, `overlay-runtime-bootstrap*`, `overlay-runtime-options*`, `overlay-window-runtime-handlers*`, `tray-runtime-handlers*`, and `cli-command-context-factory*` (8/8).
+- [2026-02-20T11:06:51Z] scope: staging `src/main.ts`, new overlay bootstrap handlers module/tests, and subagent bookkeeping only.
 - [2026-02-20T10:17:29Z] progress: extracted Yomitan settings opener composition from `src/main.ts` into `src/main/runtime/yomitan-settings-runtime.ts`; `main.ts` now uses `createYomitanSettingsRuntime(...)` and consumes `openYomitanSettings` from that runtime.
