# Live acquisition validation

Validated on 2026-07-20 against the official AMI host.

## Discovery-only scale check

- Meetings queried: 100
- Meetings with candidates: 98
- Low-size close-up AVI candidates: 392
- Individual headset WAV candidates: 392
- Total official media candidates: 784
- Media downloaded: no
- License accepted by discovery: no

The two missing meeting variants were `IS1002a` and `IS1005d`. Their absence did
not stop the inventory; the downloader records available meetings and remains
resumable.

## Camera/headset mapping check

- Scenario meetings parsed from official documentation: 135
- Camera/headset signal pairs: 540
- Stable speaker IDs: 136
- Mapping page SHA-256:
  `185bca2fa07fd0a4e99004a8fcd228058f9445874391d107ab0c0c97fcbe2abc`

## Local tests

- Acquisition and manifest unit tests: 6 passed
- PyTorch model forward/backward/export self-test: passed
- Colab kit structural validator: passed

These checks validate discovery, mapping, safety boundaries, and model code
execution. They are not detector-accuracy evidence and do not replace training,
held-out evaluation, calibration, or shadow-mode release gates.
