# Dependency graph
requires:
  - phase: 05-proximity-algorithm
    provides: ProximityAlgorithm with fixed-size buffer and hysteresis detection
  - phase: 06-system-integration
    provides: HidDevice/DeviceProvider wiring with pipe status output
provides:
  - Runtime-configurable average length via VRSettings
  - Verbose logging toggle for dev debugging
  - Configurable HID report rate
  - Extended status output with config values
affects: [07-02-validation]

# Phase 07 Plan 01: VRSettings Configuration Summary

**VRSettings-based runtime config for report_rate_ms, log_verbosity, moving_avg_length with error-checked defaults and extended status output**

## Performance

- **Duration:** 3 min
- **Started:** 2026-03-23T04:44:05Z
- **Completed:** 2026-03-23T04:47:00Z
- **Tasks:** 2
- **Files modified:** 6

## Accomplishments
- ProximityAlgorithm now uses vector buffer with runtime-configurable average length
- DeviceProvider reads 3 settings from steamvr.vrsettings driver_BeyondProximity section on startup
- Verbose logging in both HID reader thread and RunFrame for dev debugging
- Status pipe output extended with report_rate_ms, log_verbosity, moving_avg_length

## Task Commits

Each task was committed atomically:

1. **Task 1: Parameterize ProximityAlgorithm and HidDevice** - `1231bb8` (feat)
2. **Task 2: Read VRSettings, wire to subsystems, extend status** - `bd241ca` (feat)

## Files Created/Modified
- `src/hid/proximity_algorithm.h` - Vector buffer, runtime avgLength constructor param
- `src/hid/proximity_algorithm.cpp` - Constructor init list, std::fill, m_averageLength references
- `src/hid/hid_device.h` - Constructor params (avgLength, logVerbose), m_logVerbose member
- `src/hid/hid_device.cpp` - Constructor delegation, verbose raw_prox logging
- `src/driver/device_provider.h` - Config members (m_reportRateMs, m_movingAvgLength, m_logVerbose)
- `src/driver/device_provider.cpp` - VRSettings read, HidDevice wiring, RunFrame verbose logging, status extension

## Decisions Made
- Vector buffer replaces fixed std::array for runtime-configurable average length
- Constructor injection pattern passes avgLength and logVerbose through HidDevice to ProximityAlgorithm
- VRSettings read uses per-key error checking with individual defaults and clamping ranges

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- All configuration plumbing in place, ready for 07-02 validation plan
- CONF-01 code complete (settings read from vrsettings)
- CONF-02 already satisfied by Phase 4 (user_trim from flash unchanged)
- CONF-03 already satisfied (user_trim adjustable via flash/Beyond Utility)

## Self-Check: PASSED

All 6 modified files verified present. Both task commits (1231bb8, bd241ca) verified in git log.
