//! File attestation and integrity verification
//!
//! This module provides types, digest computation, and trust policy primitives
//! for verifying the provenance and integrity of files before they are consumed.
//!
//! # Architecture
//!
//! ```text
//! file --> digest --> blocklist check --> bundle verify --> publisher match --> allow/deny
//! ```
//!
//! The library provides attestation primitives reusable by all language bindings.
//! Signing, CLI commands, and policy file loading live in `nono-cli`.
//!
//! # Components
//!
//! - **Types** ([`types`]): Trust policy, publisher identity, blocklist, verification result
//! - **Digest** ([`digest`]): SHA-256 digest computation for files and byte slices
//! - **Policy** ([`policy`]): Loading, merging, and evaluation of trust policies
//! - **DSSE** ([`dsse`]): Dead Simple Signing Envelope parsing, PAE construction, in-toto statements
//! - **Bundle** ([`bundle`]): Sigstore bundle loading, verification, and identity extraction
//! - **Signing** ([`signing`]): Keyed ECDSA P-256 signing and Sigstore bundle construction
//!
//! # Security
//!
//! - Blocklist checked before any cryptographic verification (fast reject)
//! - Enforcement modes: `Deny` (hard block), `Warn` (log + allow), `Audit` (silent allow + log)
//! - Project-level policy cannot weaken user-level enforcement
//! - No TOFU: files must have valid signatures from trusted publishers on first encounter
