## Current Test

[testing complete]

## Tests

### 1. Status command shows algorithm diagnostics
expected: Run `beyond_prox_ctl.exe status`. Output includes all original fields PLUS four new fields: averaged_prox=N, detected=true/false, eff_thresh=N, samples=N.
result: pass
note: Initially failed due to double cal-subtraction bug. Fixed by removing redundant calibration subtraction and incorrect range check in ProcessSample. Re-tested and passed.

### 2. Person detected when headset is on head
expected: Place Beyond 2 on your head, wait ~10 seconds, run `beyond_prox_ctl.exe status`. Expected: detected=true, and averaged_prox value is above eff_thresh value.
result: pass

### 3. Person removed when headset is off head
expected: Remove Beyond 2 from your head, wait ~10 seconds, run `beyond_prox_ctl.exe status`. Expected: detected=false, and averaged_prox value is below eff_thresh value.
result: pass

### 4. Samples counter is incrementing
expected: Run `beyond_prox_ctl.exe status` twice with a few seconds between. The samples=N value should be higher on the second run.
result: pass

### 5. Algorithm verification script passes
expected: Run `powershell -ExecutionPolicy Bypass -File scripts/verify_algorithm.ps1`. Expected: 8/8 automated checks pass.
result: pass

### 6. State transition logging in vrserver
expected: Check SteamVR vrserver log for "Proximity: Algorithm reset" message (from driver startup). If you've put on/removed the headset, also expect "person detected" and "person removed" log entries.
result: pass
note: Confirmed in vrserver.txt — Algorithm reset on startup, person detected/removed transitions logged with avg and thresh values.
