RoboAgent Guard for Safety and Privacy Validation

[subhashchandra001]

Summary

RoboAgent Guard adds safety and privacy validators for robot-agent traces involving navigation, SLAM, mapping, sensor data, and privacy-sensitive information.

Motivation

Robot-agent traces may include commands or observations such as cmd_vel, navigation_goal, slam, map_save, raw_camera, camera_frame, lidar_scan, person_detected, and private_zone.

These messages should include explicit safety, supervisor-approval, risk-check, or privacy-filtering markers before they are treated as acceptable robot actions or sensor-sharing events.

Changes

• Adds roboagent_guard to the validator registry.

• Adds validate_roboagent_guard_safety_markers.

• Adds validate_roboagent_guard_privacy_markers.

• Detects robot navigation, SLAM, mapping, and sensor messages without safety markers.

• Detects privacy-sensitive camera, mapping, person-detection, and private-zone messages without privacy markers.

• Adds focused tests for:

  • safety-marker pass
  • safety-marker failure
  • non-robot message handling
  • privacy-marker pass
  • privacy-marker failure

Verification

• uv run pytest packages/nest-core/tests/test_validators.py -q

  • 88 tests passed

• make ci-local

  • Ruff checks passed
  • Formatting checks passed
  • Pyright passed
  • Full pytest suite passed

Scope

This PR is intentionally limited to the validator registry, RoboAgent Guard validators, and their tests.
