+# Phase 02 Plan 06: Main Entry Point Summary
+
+**asyncio REPL entry point wiring AudioPlayer + ChoreographyScheduler + BeatDetector + ESP32Transport into `python -m led_sync <ip>` CLI**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-04-03T12:53:35Z
+- **Completed:** 2026-04-03T12:58:00Z
+- **Tasks:** 1 of 2 (Task 2 is hardware checkpoint — awaiting user verification)
+- **Files modified:** 3
+
+## Accomplishments
+
+- Created `src/led_sync/main.py` with AppState, full D-13 REPL command set, asyncio REPL loop
+- Created `src/led_sync/__main__.py` enabling `python -m led_sync` invocation
+- Added `led-sync` script entry point to pyproject.toml
+- `uv run python -m led_sync --help` verified working; AST validation confirmed all module imports
+
+## Task Commits
+
+1. **Task 1: Main entry point and asyncio REPL** - `e544d57` (feat)
+
+**Checkpoint reached:** Task 2 (hardware acceptance test) requires user verification on Raspberry Pi + ESP32.
+
+## Files Created/Modified
+
+- `/home/claude/keineahnungirgendeintesthalt/src/led_sync/main.py` — Full CLI entry point: AppState, handle_command dispatcher, repl(), async_main(), main()
+- `/home/claude/keineahnungirgendeintesthalt/src/led_sync/__main__.py` — Module invocation entry (delegates to main.py:main)
+- `/home/claude/keineahnungirgendeintesthalt/pyproject.toml` — Added [project.scripts] led-sync entry point
+
+## Decisions Made
+
+- AppState class holds all module instances — structured for Phase 3 Textual TUI to import and reuse these same objects without refactoring
+- BeatDetector created lazily on `beat on` command — avoids claiming audio device at startup
+- `run_in_executor(None, input, "> ")` pattern for non-blocking stdin in asyncio — standard pattern for asyncio REPLs per plan research
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None — no external service configuration required. Hardware verification in Task 2 is a checkpoint for the user to perform on-device.
+
+## Next Phase Readiness
+
+- Phase 2 headless CLI is complete pending hardware acceptance in Task 2
+- Phase 3 Textual TUI can import `AppState`, `handle_command`, and module instances from `main.py` directly
+- All module APIs are asyncio-compatible: AudioPlayer (thread), BeatDetector (call_soon_threadsafe bridge), ChoreographyScheduler (asyncio Task), ESP32Transport (DatagramProtocol)
