Crate lib_q_duplex_aead 

Duplex-sponge AEAD built from Keccak-f[1600] (SHA-3 family permutation).

Rate 136 bytes, 256-bit tag, 256-bit key, 128-bit nonce. Associated data is absorbed before plaintext duplex steps; the tag is the first 32 bytes of the outer state after processing.

Security

This construction follows the duplex-sponge model (Bertoni et al.). The permutation is NIST-standardized SHA-3 / FIPS 202; this crate defines a non-standard AEAD mode on top of it. Use only after independent review for your threat model.
