TASK-103	Extract Jellyfin runtime wiring from main.ts composition root	To Do		2026-02-22 07:13	2026-02-22 07:13	refactor maintainability jellyfin	TASK-102 TASK-94 TASK-97	medium

Description

src/main.ts remains oversized (3014 LOC) and still carries a dense Jellyfin wiring block (roughly main.ts:1145-1565) despite composition-root refactors.

Goal: finish extraction of Jellyfin-specific dependency construction and command/setup orchestration into dedicated runtime composer modules so main.ts remains thin and legible.

Action Steps

1. Extract Jellyfin config/client-info/auth/list/play/setup dependency builders from src/main.ts into focused files under src/main/runtime/composers/.
2. Create one Jellyfin composition entrypoint that returns fully wired handlers used by main.ts.
3. Remove duplicated inline adapter lambdas from main.ts; keep only high-level invocation points.
4. Add/expand composer seam tests for extracted Jellyfin module boundaries.
5. Re-run fan-in and compile checks to ensure extraction does not regress runtime wiring.

Acceptance Criteria

• #1 src/main.ts no longer contains the full Jellyfin deps-building block.
• #2 New Jellyfin composer modules have focused tests covering handler wiring.
• #3 bun run check:main-fanin stays green after extraction.
• #4 bun run build and bun run test:core:src pass.

Definition of Done

• #1 src/main.ts LOC reduced materially from current baseline.
• #2 Jellyfin runtime wiring is centralized in named composer module(s) with clear ownership docs.
• #3 No behavior regressions in Jellyfin command/setup flows.
