Merge Risk: 🟡 Moderate · up to BLS-IES adds public encryption and decryption using unauthenticated AES-CBC, allowing tampered or mismatched inputs to yield successful but corrupted plaintext instead of an integrity error. Downstream users could accept that data as valid, so the change needs explicit security-owner acceptance or an authenticated envelope before it is merge-ready. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

tests to cover the chosen behavior.
