Deterministic bridge (cra_safety_bridge.py): a cyber finding's attack capability (remote_actuation / code_tampering / integrity_loss / auth_bypass, derived from its CRA category) is matched against what each CE safety function is vulnerable to. A match re-opens the mitigated hazard, flags the finding safety_impact (which floors it to P0), and produces the cross-link. Endpoint accepts safety_functions; frontend passes the project's safety functions and renders the LIVE cross-links (no more hardcode). Safety functions are demo input now; come from the CE risk assessment in production. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

"""Standalone CRA cyber risk-assessment endpoint.
|
|
|
|
POST /api/v1/cra/assess — takes the findings the external repo-scanner already
|
|
produced and returns the deterministic CRA assessment: each finding mapped to
|
|
the CRA Annex I requirement(s) it violates, a risk level, the curated CRA
|
|
measures, and the NIST 800-53 / OWASP Top 10 golden-set crosswalk.
|
|
|
|
Project-less by design: works standalone for ANY customer — including those with
|
|
no CE risk assessment and no FMEA yet (the mandatory baseline). Reuses the fully
|
|
tested mapper; no DB, no LLM, no RAG. Same logic the MCP server exposes.
