pub fn aggregate_partials(
partials: &[PartialDecryption],
threshold: u32,
blob: &EncryptedBlob,
) -> Result<Vec<u8>, EciesError>Expand description
Aggregate T partial decryptions to recover the plaintext.
Combined point = sum_i [ λ_i * partial_i ] = x * R = K (the ECDH shared secret). Derive AEAD key from X-coordinate of K, then AEAD-decrypt the blob.
