# Phase 08 Plan 02: HTTP Control API Lifecycle Wiring Summary

**HTTPControlServer wired into main.swift with background Task startup on port 8780, ARC retention, and graceful fallback on bind failure**

## Performance

- **Duration:** 1 min
- **Started:** 2026-03-26T17:47:23Z
- **Completed:** 2026-03-26T17:49:00Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- HTTPControlServer and SettingsStore created and started in main.swift after TTSEngine init
- HTTP server launches in background Task with graceful warning-only fallback if port is busy
- nonisolated(unsafe) keepAlive references prevent ARC deallocation of server and settings store
- Fixed deprecated FlyingFox `server.start()` to `server.run()` (zero warnings in build)
- Release build succeeds with all 6 API endpoints routed

## Task Commits

Each task was committed atomically:

1. **Task 1: Wire HTTPControlServer into main.swift with lifecycle management** - `964081ff` (feat)
2. **Task 2: Build verification and endpoint smoke test** - verification only, no code changes

## Files Created/Modified

- `plugins/claude-tts-companion/Sources/claude-tts-companion/main.swift` - Added SettingsStore + HTTPControlServer creation, background Task startup, and ARC retention references
- `plugins/claude-tts-companion/Sources/claude-tts-companion/HTTPControlServer.swift` - Fixed deprecated `server.start()` to `server.run()`

## Decisions Made

- HTTP server starts in a background Task so it does not block the main thread or NSApplication run loop
- Failure to bind port logs a warning but does not crash the binary (graceful degradation)
- Fixed FlyingFox deprecated API (`start()` renamed to `run()`) to eliminate compiler warnings

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Fixed deprecated FlyingFox server.start() API**

- **Found during:** Task 1 (build verification)
- **Issue:** FlyingFox 0.26.2 renamed `start()` to `run()`, producing deprecation warning
- **Fix:** Changed `server.start()` to `server.run()` in HTTPControlServer.swift
- **Files modified:** HTTPControlServer.swift
- **Verification:** Clean build with zero warnings
- **Committed in:** 964081ff (Task 1 commit)

---

**Total deviations:** 1 auto-fixed (1 deprecated API)
**Impact on plan:** Trivial rename fix, no scope creep.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Phase 8 complete: HTTP control API fully integrated and building
- All 6 endpoints (health, settings read/write, subtitle show/hide) routed and ready
- SwiftBar integration (Phase 9) can now call localhost:8780 to control the companion
- Launchd service (Phase 10) will manage the binary that now auto-starts the HTTP server

## Self-Check: PASSED
