Cross-checked cobot_biomech_limits.md against both source papers:
- Behrens et al. 2022 (Frontiers): 10 body regions spot-checked, force
values match the paper EXACTLY in both columns (pinching + impact).
- Park et al. 2019 (PLOS ONE): lowest/highest/range pressure values exact.
Fix: 28 -> 29 body locations; add a verification stamp. Threshold VALUES
were already correct (no data change), so no RAG re-ingest needed.

Versioned, license-tagged source docs for the multi-layer GT knowledge base,
ingested into the new core RAG collection bp_iace_safety_kb (whitelisted in
the RAG search handler):
- prism_risk_methodology.md — OPSS PRISM v2 (OGL v3): full severity(4)×
probability(8) → risk-level matrix (Serious/High/Medium/Low), RAPEX-aligned.
- cobot_biomech_limits.md — CC BY 4.0 papers (Behrens 2022 / Park 2019):
force (N) & pressure (N/cm²) pain thresholds by body region (the data behind
ISO/TS 15066, cited from the open papers — standard tables NOT reproduced).
- hse_example_risk_assessments.md — HSE (OGL v3): qualitative hazard→control.
- osha_robot_safety.md — OSHA OTM (public domain): 250 mm/s teach anchor,
robot hazard taxonomy, safeguarding hierarchy.
No DIN/EN/ISO/IEC/DGUV content reproduced; each doc states its license + attribution.

US severity anchor complementing ESAW: BLS Census of Fatal Occupational
Injuries (public domain), event/exposure distribution 2023-24 + the
machine-relevant "Contact incidents" breakdown (struck/caught/compressed
by running powered equipment: 226/213). Key finding: in MANUFACTURING,
contact is the leading fatal event (104/353 = 29.5%) — independent support
for the model's mechanical-contact emphasis. Ingested into the core RAG
collection bp_iace_accident_stats.

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.
