 ## Current Work (newest first)
 
+- [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.
+- [2026-02-20T10:17:29Z] progress: added `src/main/runtime/yomitan-settings-runtime.test.ts` for composed runtime behavior.
+- [2026-02-20T10:17:29Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + focused suites pass for `yomitan-settings-runtime*`, `yomitan-settings-opener*`, `yomitan-extension-runtime*`, `cli-command-context-factory*`, and `tray-runtime-handlers*` (7/7).
+- [2026-02-20T10:17:29Z] scope: staging `src/main.ts`, new yomitan settings runtime module/tests, and subagent bookkeeping only.
 - [2026-02-20T10:15:51Z] progress: extracted overlay window factory composition from `src/main.ts` into `src/main/runtime/overlay-window-runtime-handlers.ts`; `main.ts` now composes overlay/main/invisible window handlers via one runtime factory.
 - [2026-02-20T10:15:51Z] progress: added `src/main/runtime/overlay-window-runtime-handlers.test.ts` for composed window handler wiring.
 - [2026-02-20T10:15:51Z] test: `bun run build` pass (expected macOS helper Swift cache fallback) + focused suites pass for `overlay-window-runtime-handlers*`, `overlay-window-factory*`, `overlay-runtime-bootstrap*`, `tray-runtime-handlers*`, and `cli-command-context-factory*` (9/9).
