Conversation
- Implement pre-hashing (SHA-256) in `safeEqual` and `safeEqualText` to prevent length-based timing attacks. - Update `safeEqualText` in `proxy.js` to be async for Edge Runtime compatibility. - Add `hasSensitiveContent` filtering to Telegram message and journal handlers to prevent secret persistence. - Add security hardening test suite and journal critical learnings.

🛡️ Sentinel: Security Hardening Report
🚨 Severity: HIGH
💡 Vulnerability: Length-based timing attacks on secrets and accidental persistence of sensitive data (API keys, tokens).
🎯 Impact: Attackers could potentially guess secret lengths through timing side-channels. Secrets could be stored in plaintext in the database via Telegram messages or journal entries.
🔧 Fix:
✅ Verification: New
