Fix Strix findings and verify

Turn validated Strix findings into minimal, correct fixes — and prove they work by re-scanning.

1. Triage

Get the findings from wherever the scan ran:

• OSS CLI — artifacts in strix_runs/<run-name>/:
  • vulnerabilities/*.md — one finding per file: description, severity, PoC steps or script, affected code locations, remediation guidance.
  • vulnerabilities.json — the same findings as JSON (ids, severity, CWE/CVE, code_locations with fix_before/fix_after suggestions when available).
• Cloud (app.strix.ai) — pull findings with the CLI: strix cloud vulns list --scan-id <scan-id> --json (or strix cloud scans get <scan-id> --json | jq '.vulnerabilities', or strix cloud vulns list --severity critical org-wide). Each finding carries severity, cwe, endpoint, method, impact, technical_analysis, poc_description, poc_script_code and, for code findings, code_file/code_diff/code_before/code_after. After a fix is verified, mark it with strix cloud vulns update <id> --status fixed. See the managed-pentesting-with-strix skill for strix cloud login and scopes.

Order work by severity: critical → high → medium → low. Every Strix finding was validated with a working proof-of-concept, so do not dismiss findings as false positives without re-testing the PoC yourself.
