P6-R2: Session manager — save/load mixer states with setlists and snapshots
Lint & Validate / lint (push) Has been cancelled
Core session management:
- MixerSession: full mixer state as versioned JSON (channels, buses, routing, plugins, MIDI, transport, automation)
- SessionManager: save/load/list/delete/rename/duplicate/import/export sessions to ~/.config/rpi-mixer/sessions/
- Setlist: ordered collection of sessions with transition types (cut, crossfade, wait)
- SnapshotEngine: instant scene capture/recall with persistence, categories, next/prev
API endpoints (all under /api/v1/):
- GET/POST/DELETE /sessions — list, save, load, delete, info
- POST /sessions/{name}/rename, /duplicate, /export, /import
- GET/POST/DELETE /setlists — list, save, load, delete
- GET/POST/DELETE /snapshots — list, capture, recall, delete, next, prev
- GET/POST /sessions/autosave — status, enable, disable
Web UI:
- Sessions tab: full session browser with load/delete/duplicate/export
- Setlists subtab: create/edit/activate setlist with entry management
- Snapshots subtab: capture/recall with category badges
- Auto-save status indicator
- Import/export all sessions as zip
Kivy touchscreen UI:
- New SES tab with sessions/setlists/snapshots sub-views
- Touch-optimized cards with save/load/delete actions
Tests: 51 new tests, 735 project total — all passing

P6-R1: Audio/video streaming pipeline
Lint & Validate / lint (push) Has been cancelled
- src/streaming/ module: camera detection (USB webcam + Pi Camera Module via
v4l2/libcamera), GStreamer pipeline builder with V4L2/OMX/x264 h264 encoders,
platform presets (YouTube, Twitch, Facebook, custom RTMP), streamer lifecycle
manager with auto-reconnect, scene management, stream statistics
- Keyboard shortcut controller (evdev + pynput fallback) for stream control:
Ctrl+Shift+S (start/stop), Ctrl+Shift+1-9 (scene switch), Ctrl+Shift+R (reconnect)
- REST API: /api/v1/stream/* endpoints for start/stop/status, scenes, cameras,
platforms, and hotkey listing — integrated into NetworkServer
- StreamStateProvider bridging layer connects REST routes to Streamer instance
- GStreamer pipeline supports ALSA/JACK/PulseAudio audio capture and
V4L2/libcamera video capture with H.264 hardware encoding on RPi4B
- Low-latency streaming settings for live performance (zerolatency, no B-frames)
- 89 streaming tests (709 total project tests pass)

P3-R3: Multi-track recording engine
Lint & Validate / lint (push) Has been cancelled
- WAV writer with streaming support for 16/24/32-bit integer and 32-bit float
- MultiTrackRecorder with per-channel arming, arm state machine, write-ahead
buffer queues decoupling JACK real-time thread from SD card I/O
- Punch in/out recording on individual channels with punch region tracking
- Session file format (JSON): session metadata, takes, tracks, mixer state,
punch regions, serialization round-trip
- Take management: create, delete, rename, list, track association
- Stereo bounce engine with pan law (-3dB constant power), normalisation,
master bus volume/mute/dim, block-based processing for memory efficiency
- Disk space monitor with configurable warning/critical thresholds, estimated
recording time remaining, background polling, callback on threshold change
- 117 tests: sample conversion, WAV header validation, recorder lifecycle,
session CRUD, serialization, bounce with pan/normalisation/master, integration
Integrates with JACK capture ports → mixer → recording ports → disk.
Architecture: JACK callback → recorder.write() → buffer queue → writer thread → WAV files.

P5-R3: Web app frontend — touch-optimized mixer UI
Lint & Validate / lint (push) Has been cancelled
- Complete SPA rewrite: 4 tabs (Mixer, Routing, Plugins, Sessions)
- Touch-optimized faders with animated level meters (dark theme)
- Channel strips: fader, mute, solo, pan, EQ modal with 3-band EQ + compressor + gate
- Routing matrix: drag-and-drop source→destination, connection list with mute toggles
- Plugin control: per-channel plugin cards with bypass and parameter sliders
- Session browser: list/load/save/delete scenes via REST API
- Transport controls: play, stop, record, loop, locate (keyboard shortcuts: space=play)
- Responsive: phone portrait (touch-first), landscape, tablet, desktop
- Zero dependencies: vanilla JS + WebSocket only
- Backend: added DELETE /api/v1/scenes/{name} endpoint, wired delete_scene callback
