Module timing 

Timing attack prevention utilities

This module provides utilities to prevent timing attacks in cryptographic operations.

AEAD decrypt and verification

For authenticated decryption, see the implementor contract on crate::traits::Aead: symmetric work should precede verification branches where required by the threat model, while the public Result API still exposes success versus failure at the boundary unless a higher layer mediates timing. For an opt-in semantic decrypt surface (Ok versus AuthenticationFailed without plaintext on failure), see crate::AeadDecryptSemantic and workspace ADR docs/adr/003-aead-decrypt-layers.md.
