## Current Work (newest first)
- [2026-02-21T03:41:10Z] handoff: completed TASK-94 slice extraction for jellyfin/anilist composer modules; `main.ts` now consumes `composeJellyfinRemoteHandlers` + `composeAnilistSetupHandlers`; added composer tests; tightened fan-in guard to `<=110` import lines and `<=11` unique runtime paths.
- [2026-02-21T03:41:10Z] test: `bun run build`, `node --test dist/main/runtime/composers/anilist-setup-composer.test.js dist/main/runtime/composers/jellyfin-remote-composer.test.js`, `bun run test:config:dist`, `bun run test:core:dist`, `bun run check:main-fanin`, `bun run check:main-fanin:strict`, `bun run check:file-budgets`.
- [2026-02-21T03:24:30Z] intent: execute TASK-94 with batch extraction (startup, overlay, jellyfin/anilist, ipc/shortcuts), tests, fan-in threshold tighten, backlog updates.
- [2026-02-21T03:24:30Z] planned files: `src/main.ts`, `src/main/runtime/composers/*`, `src/main/runtime/registry.ts`, `src/main/runtime/*composer*.test.ts`, `scripts/check-main-runtime-fanin.ts`, `backlog/tasks/task-94 - Reduce-main.ts-to-thin-composition-root.md`, `backlog/tasks/task-71 - Split-main.ts-into-domain-runtime-modules-round-2.md`.
- [2026-02-21T03:24:30Z] assumptions: prior TASK-71 domain barrels + registry already landed in working tree; continue from current dirty state without reverting unrelated edits.

## Assumptions
- `TASK-94` scope is single-ticket execution from existing branch state; no new worktree requested by user.
- Existing uncommitted edits are intentional and should remain.

## Open Questions / Blockers
- none

## Next Step
- Continue TASK-94 by extracting startup/overlay/ipc/shortcuts deps-builder clusters into composer modules to finish thin composition-root target.
