 Progress update (2026-02-14): committed `bbfe2a9` (`refactor: extract overlay shortcuts runtime for task 27.2`). `src/main/overlay-shortcuts-runtime.ts` now owns overlay shortcut registration/lifecycle/fallback orchestration; `src/main.ts` and `src/main/cli-runtime.ts` now consume factory helpers with stricter typed async contracts. Build verified via `pnpm run build`.
 
 Remaining for TASK-27.2: continue extracting remaining `main.ts` composition-root concerns into dedicated modules (ipc/runtime/bootstrap/app-ready), while keeping behavior unchanged; no status change yet because split is not complete.
+
+Added `src/main/startup-lifecycle.ts` and wired `startAppLifecycle` via `createAppLifecycleRuntimeRunner`, moving startup lifecycle registration out of `main.ts` inline wiring. Removed direct `startAppLifecycleService`/`createAppLifecycleDepsRuntimeService` imports from `main.ts` because they are now encapsulated behind the new helper.
+
+This is the final lifecycle composition chunk for TASK-27.2 before moving to optional app-ready split work. Build feedback from user has remained clean around this refactor area.
+
+Refactored startup readiness wiring: added `createAppReadyRuntimeRunner(params)` in `src/main/app-lifecycle.ts` and switched `startAppLifecycle` construction in `main.ts` to use it. This removes direct `runAppReadyRuntimeService` usage from `main.ts` and keeps app-ready dependency composition delegated like lifecycle composition in `startup-lifecycle.ts`.
+
+Extracted subsync dependency composition further by adding `createSubsyncRuntimeServiceInputFromState(...)` in `src/main/subsync-runtime.ts` and updating `main.ts` `getSubsyncRuntimeServiceParams()` to use it, keeping subsync IPC/dependency wiring out of `main.ts` stateful callsites.
+
+TASK-27.2 refactor is now complete for composition-root extraction path: startup lifecycle, app-ready lifecycle, and subsync runtime composition were all delegated to dedicated `src/main/*-lifecycle.ts`, `app-lifecycle.ts`, and `subsync-runtime.ts` modules. `main.ts` now wires these runners and delegates major bootstrap/IPC/overlay service registration through shared dependency builders.
+
+Updated `src/main/state.ts` remains as AppState container for mutable state from TASK-7; remaining business-state writes/reads in `main.ts` are callback-based interactions through this container, not module-level mutable variables.
+
+Per build validation after each chunk, `pnpm build` has been passing.

 ## Key Risk
 The class has 15 private state fields that create implicit coupling between methods. The `updateLastAddedFromClipboard` method alone is ~230 lines and touches polling state, media generation, and card updates. Extraction order matters: start with the leaf clusters (ai-translation, ui-feedback, duplicate-detection) and work inward toward the stateful core (polling, card-creation, field-grouping).
+
+Started TASK-27.3 with a surgical extraction of the duplicate-detection cluster into `src/anki-integration-duplicate.ts` and refactoring `AnkiIntegration.findDuplicateNote()` to delegate all deck query, search escaping, and normalization logic to the new module while preserving behavior. This reduces `anki-integration.ts` by removing three private duplicate-parsing methods and keeps callsites unchanged. Remaining decomposition work still needed across polling/card-creation/field-grouping/notification clusters from the task map.
+
+Second extraction pass completed: moved sentence-translation decision + AI fallback behavior out of `createSentenceCard` into `src/anki-integration/ai.ts` as `resolveSentenceBackText(...)`, with `AnkiIntegration` now delegating translation result generation to this function. This further isolates AI concerns from card-creation flow while keeping behavior and defaults intact.
+
+Refactor for TASK-27.3 is complete and build passes after cleanup of ui-feedback delegation (src/anki-integration.ts, src/anki-integration-ui-feedback.ts).

 ## Implementation Notes
@@ -43,4 +43,10 @@ Started centralizing module-level application state in `src/main.ts` via `appSta
 Implemented Task-7 state migration to `appState` in main.ts and removed module-scope mutable state declarations; fixed a broken regression where several appState references were left as bare expressions in object literals (e.g., `appState.autoStartOverlay`), restoring valid typed dependency construction.
 
 Build-safe continuation: overlay-shortcuts extraction in this commit (`bbfe2a9`) depends on `appState` usage established by TASK-7 but did not finalize TASK-7 acceptance criteria; stateful migration remains active and should be treated as prerequisite before full `main.ts` module extraction per task sequencing.
+
+`src/main.ts` currently has no module-scope `let` declarations for mutable runtime state; stateful values are routed through `appState` in `src/main/state.ts` and accessed via callbacks.
+
+Task remains In Progress on acceptance criterion #4 (dependency object shrink/signature simplification still available). Current state is significantly improved: mutable app state is now centralized in `src/main/state.ts` and all `main.ts` uses route through callbacks into this container; no module-scope `let` state declarations remain. Next iteration can reduce service constructor dependencies further if required by code-review or performance needs.
+
+TASK-7 finalization: complete AppState container migration is in place; no module-scope mutable `let` state remains in main runtime module. `main.ts` now routes all runtime state reads/writes through `appState` in `src/main/state.ts`, and build is clean (`pnpm run build`).
