TRAIGA Safe Harbor

Gated three-step chain for the Texas Responsible AI Governance Act (Tex. Bus. & Com. Code Ch. 552-553, HB 149, effective 2026-01-01) affirmative defense under §553.106. Step 1 assesses TRAIGA applicability and intentional prohibited-use assertions; step 2 (the shipped NIST AI RMF function mapper) computes RMF coverage; step 3 assembles the evidence pack. Two §21.4 decision gates route early exits when a prohibited use is detected or RMF coverage falls short of the substantial-compliance bar.

1 ROOT + GATE node §21.4 gate

TRAIGA Exposure Assessor art-313-traiga-exposure-assessor

prohibited_use_detected feeds the gate. A detected prohibited use exits the chain; otherwise the RMF mapping stage runs.

△ Gate: if /prohibited_use_detected == true → exit (end) | else (default) → continue to NIST AI RMF mapper

2 D2 + GATE node §21.4 gate

NIST AI RMF Function Mapper art-174-nist-ai-rmf-function-mapper

coverage_band feeds the gate. Minimal or Partial coverage exits (does not meet the substantial-compliance bar); Substantial or Comprehensive continues to the pack builder.

△ Gate: if /coverage_band in [Minimal, Partial] → exit (end) | else (default) → continue to Safe Harbor Pack Builder
