Executes the accident-statistics pipeline for the risk anchors:
- Refresh contactModeEvidence with real Eurostat ESAW figures
(dataset hsw_ph3_08, reference year 2023): impact 24.0%/21.4%,
struck-by 13.0%/23.8%, sharp 14.5%, trapped/crushed 13.8% (fatal),
+ new physical/mental-stress mode 24.7% → ergonomic. GT-calibrated
tier VALUES unchanged; the real data confirms the ordering.
- Add the versioned source document (datasources/esaw_accident_stats_2023.md,
ESAW CC BY 4.0 + OSHA public-domain context) that is ingested into the
core RAG collection bp_iace_accident_stats for searchable evidence.
- Whitelist bp_iace_accident_stats in the RAG search handler so seeding
can full-text search the statistics with citation at seed time.
Two-layer design: the small license-tagged code table stays the deterministic
tier/citation lookup; the RAG holds the searchable source evidence.

IP/copyright fix: ComputePLr reproduced the EN ISO 13849-1 Anhang A risk-graph
decision table (S/F/P -> PLr a..e) and SeverityToS/ExposureToF its parameter
binning, emitted into every hazard description. Removed — we may not reproduce
DIN/Beuth norm logic.
Replaced with BreakPilot's OWN risk model:
- risk_estimation.go: probability (W) + avoidance (P) estimated from public,
permissively-licensed accident statistics (Eurostat ESAW, CC BY 4.0) by
contact mode, calibrated to our ground-truth corpus; own risk index + bands.
- iace_handler_init.go now emits "Risikoeinschaetzung (BreakPilot-Modell):
S F W P -> Risiko: <level>" instead of the norm PLr string.
- DATA_SOURCES.md: data provenance + license register (ESAW CC BY 4.0; BLS/OSHA
public domain; HSE OGL; DGUV + DIN/Beuth explicitly excluded).
- gt_risk_benchmark_test.go: first GT validation of risk numbers — W within +-1
99%, P 93% vs the professional across both ground truths.
Removed risk_graph_test.go (pinned the reproduced norm table).
