Bottom Line: The codebase has undergone major hardening from v1.1.0 to v3.2.1. The original 7 critical issues have been resolved. Security posture is now production-grade with HMAC webhook auth, AES-256-GCM credential encryption, PHI log redaction, audit logging, and 18 Zod validation schemas. Remaining gaps are documented in the backlog.

Key Findings — Resolved
All 5 original critical issues from the January 2026 review have been fixed:
| # |
Original Critical Issue |
Resolution |
Version |
| 1 |
Disabled Authentication (webhook bypass) |
HMAC-SHA256 mandatory in production, fail-fast Zod validation |
v2.2.0 + v3.2.1 |
| 2 |
Plaintext Credentials |
AES-256-GCM encryption at rest (lib/crypto.ts) |
v3.1.0 |
| 3 |
No PHI Audit Trail |
middleware/audit.ts captures all mutations; PHI redacted from logs |
v3.1.0 + v3.2.1 |
| 4 |
CORS Wildcard |
Configured origin whitelist, enforced in production |
v2.2.0 |
| 5 |
Zero Test Coverage |
125 admin unit tests; webhook tests still needed |
v1.5.0 |
