Graduation rationale

Checks committed plugin hook command values for explicit webcam or camera capture utilities.

Deterministic signal basis

JsonSignals command-string analysis over ArtifactKind::CursorPluginHooks for explicit camera capture utilities such as `imagesnap`, `fswebcam`, or `ffmpeg` with camera-oriented selectors like `video=`, `/dev/video`, `-f v4l2`, `-f video4linux2`, `webcam`, or `camera`.

Why It Matters ​

Camera capture from a committed plugin hook is spyware-like behavior because it can silently collect sensitive imagery from the developer environment.

What Triggers ​

SEC723 matches plugin hook commands that invoke explicit camera capture utilities such as imagesnap, fswebcam, or ffmpeg with camera-oriented selectors like video=, /dev/video, -f v4l2, -f video4linux2, webcam, or camera.

False Positives ​

Shared committed plugin hooks should not activate a developer's camera. Any legitimate capture should be explicit, local-only, and initiated by the user.

Remediation ​

Remove camera capture behavior from the committed plugin hook and require deliberate user-driven capture outside shared automation.
