Critical bug fix:
- Added missing StatusHeader import (used in JSX line 215)
- Added missing LogViewer import (used in JSX line 291)
- Added missing MotorCurrentGraph import (used in JSX line 264)
These imports were referenced in JSX but not imported, causing dashboard crashes on load.
Build verification:
- 122 modules, all compiled successfully
- No errors or warnings
- Bundle: 255.38 KB main

Polls /dev/video* at 2 Hz, drives a three-state machine
(connected/disconnected/restarting) and publishes to
/saltybot/camera_status (std_msgs/String). Reconnects within
restart_grace_s (5 s) → 'restarting' held for restart_hold_s (2 s)
to signal downstream capture pipelines to restart. Scan function
is injected for offline testing. 82/82 tests pass.

Energy-gated log-mel + cosine-similarity wake-word node. Subscribes to
/social/speech/audio_raw (PCM-16 UInt8MultiArray), maintains a 1.5 s
sliding ring buffer, runs detection every 100 ms; fires Bool(True) on
/saltybot/wake_word_detected with 2 s cooldown. Template loaded from
.npy file; passive (no detections) when template_path is empty.
91/91 tests pass.

Implements ROS2 adaptive PID gain scheduler for SaltyBot with:
- Subscribes to /saltybot/speed_scale for speed conditions
- Subscribes to /saltybot/terrain_roughness for surface conditions

* D gain decreases at low speed (prevent oscillation when slow)
* I gain scales with both conditions for stability
- Publishes Float32MultiArray [Kp, Ki, Kd] on /saltybot/pid_gains
- Configurable scaling factors for each gain modulation
- Includes 18+ unit tests for gain scheduling logic
