Merge Risk: 🔵 Low · up to BLS-IES currently accepts an empty plaintext during encryption but rejects the resulting ciphertext during validation, so empty-message use may fail. The PR is otherwise mergeable with owner awareness and follow-up to align the contract and add coverage. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Keep empty-payload validity consistent.
BlsPublicKey::ies_encrypt accepts empty plaintext in pkgs/pkc/src/bls/ies_ops.rs Lines 621-626. It produces a blob with empty data. This check method then rejects the converted byte bag as InvalidCiphertextLength.
Define one contract for empty payloads. Either reject empty plaintext before encryption or accept empty data here. Update the related tests.
