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)
