Bug Fixes:
- Fixed KSUDP binary parser offsets from packed (323B) to natural C
alignment (328B) — 3 bytes padding after char identifier, 2 bytes
after 6 bools
- Fixed setup_terminal() leaving terminal in raw mode on early exit
New Features:
- Thread-safe warning buffer (warnings.rs) with TUI bar + stderr fallback
- Rewrote shift point analysis per AC forum methodology: per-gear
acceleration curves, crossover detection, same-gear merging
- UseCase::guidance() — step-by-step recording instructions
- Recording metadata enrichment in analysis responses
- recording_id field on sessions
Code Quality:
- Extracted finalize_run() helper (session.rs)
- Extracted execute_and_store_analysis() helper (api.rs)
- Extracted lerp_search<T>() generic helper (analysis.rs)
Breaking API Changes:
- GET /api/use-cases: string[] -> [{id, name, guidance}[]]
- Shift point analysis: gear_ranges/shift_events -> gear_curves/crossover_points
Updated README.md with new API response examples and TUI warning bar.
- Add session layer with UseCaseSession, SessionRun, SessionManager
for use-case driven telemetry analysis (shift points, track mapping)
- Add analysis module with shift point detection (gear RPM ranges,
upshift events, recommended shift RPM) and track map reconstruction
(spline-aligned interpolation for center line from boundary runs)
- Add 9 REST API endpoints for session CRUD, run management, and
analysis triggers under /api/sessions/*
- Add RecordingManager with always-on ring buffers (5 min, 18k frames)
replacing raw binary file dumps
- Wire SessionManager in main.rs with Arc<Mutex> shared state
- Add TelemetryFrame Serialize derives for JSON API output
- Fix stop_recording race: hold active lock across flush I/O
- Fix flush: separate ring buffer lock from JSON serialization
- Fix flush failure propagation: errors prevent Stopped status
- Add data_truncated flag on SessionRun for ring buffer wrap detection
- Deduplicate gear_display into shared free function
- Deduplicate session_display into closure
- Mutex poisoning recovery on all session API handlers
