//! Durable Harn session-store primitive.
//!
//! One source of truth for persisted agent/session events (`Message`,
//! `ToolCall`, `ToolResult`, `Plan`, `Compaction`, `SystemReminder`,
//! `Hypothesis`, `Receipt`, `Reminder`, `PermissionDecision`, plus
//! arbitrary `Custom` shapes), snapshots, replay, fork/truncate, signed
//! receipts (Ed25519 over canonical JSON), and retention. Server and host
//! adapters can layer transport, auth, and product policy on top without
//! reimplementing transcript storage semantics.
//!
//! ## Layout
//!
//! - [`event`] - event taxonomy and canonical JSON encoder
//! - [`identity`] - typed producer identity over canonical signed headers
//! - [`redaction`] - dependency-inverted event redaction contract
//! - [`signing`] - Ed25519 chain hashes and receipt signatures
//! - [`store`] - public `SessionStore` trait and shared types
//! - [`memory`] - in-memory backend for tests and headless dev
//! - [`sqlite`] - persistent SQLite backend for local/self-hosted use
//! - [`retention`] - declarative per-tenant retention policy
