Scan notes

Automated scan: review (medium 22, high 2) at commit e3a2bee2a2c0 on 2026-10-17. Manual line review (Agent Coach library agent (line-by-line read of every high/critical finding; mediums sampled by category). Not an owner sign-off., 2026-10-17): pass. Highs: preinstall only enforces pnpm; postinstall runs scripts/postinstall.sh which syncs repo-local agent shims and exits if absent; env.mjs is the app's env schema; ~/.aws/credentials appears as UI text in an API-key form; gitleaks hits are model-pricing migration rows and CI placeholders.

Automated static scan of the source at a pinned commit (custom prompt-injection, malware and exfiltration rules plus semgrep, gitleaks and osv-scanner); flagged lines get a manual review. Hosted APIs with no code to scan stay at Needs review. A scan lowers risk; it doesn't prove safety.
