PAI-SF / 9 / PAI-SF-SUP-002

Staged Update Rollout with Physical Regression Testing

Objective

Prevent updates (model, firmware) from introducing unsafe physical behavior.

Staged rollout with mandatory physical safety regression testing before fleet-wide deployment.

All physical AI systems receiving model, firmware, or software updates.

Regression test results; staged rollout records. [T2/T3]

Evidence that regression testing specifically covers safety-critical behaviors, not only functional correctness.

PAI-SF-ACT-003 (actuator divergence monitoring) may detect update-induced behavior shifts post-deployment as a backstop.

Not applicable to fully air-gapped systems with no update mechanism.

Expected at Operational and High-Assurance levels.

Extends GAISSF™ change management to physical safety regression; provides update-related incident categories for UAIF™.
