reach-awareness
Post-filters vuln-detector findings by call-graph reachability from an entrypoint, so operators triage exploitable vulns first and dead-code or vendored-library hits last. Use when the developer wants to triage a vuln-detector audit.jsonl, runs /hydra:reach, asks "which of these findings are actually reachable?", or references Snyk/CodeQL/Semgrep reachability as a reference baseline. Currently scaffolded; full integration is blocked on lich exporting a persisted call-graph artifact — in graph-absent mode, every finding is preserved with reachable=null. Do not use for raw vuln scanning (see vuln-detector) or for first-pass CWE classification (see audit-trail).
