P1 of the auto-FMEA build plan: establish the public-domain methodology foundation (no AIAG-VDA/SAE/IEC tables reproduced). - fmea_data_sources.go: MIL-STD-882E severity (Cat I-IV→1-10) + probability (A-F→1-10 with per-hour λ bands), OccurrenceFromRate(λp·α), SeverityForCategory, MIL-STD-1629A CriticalityCm = λp·α·β·t. Own 1-10 projection, government-anchored. - 4 versioned source docs (MIL-STD-1629A, MIL-STD-882E, NASA RCM, FMD-91/NPRD-91) ingested into the new RAG collection bp_iace_fmea_kb (whitelisted). - Tests for all scales/mappings/criticality (green). Next (P1 step 2): fetch FMD-91/NPRD-91 bulk λ/α tables from DTIC. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
