gwk-kernel 0.0.2

//! The GridWork kernel: the PostgreSQL implementation behind the `gwk`
//! contract.
//!
//! `gwk-domain` says WHAT the contract is; this crate is one engine's answer to
//! it. The split is load-bearing — everything backend-specific (this crate, the
//! `gwk_internal` schema, the migrations beside it) stays on this side of the
//! line, and `schema/0001_contract.sql` stays engine-neutral so a second
//! backend has something to conform to.
//!
//! What is here so far: configuration, the embedded contract DDL and its
//! fingerprint, the one-shot initializer, the fenced append store, the epoch
//! that seals a fresh log until it is activated, the work lifecycle's command
//! path and projections, and the blob spine — the encrypted container format
//! and the store that dedups, pins, sweeps, rotates and shreds it, the
//! projection snapshots, and the recovery that decides what a restart may claim
//! about them. The wire server lands on top of them.

// The DDL is contract, so it is generated into `gwk-domain` and re-exported here
// — the paths every caller already uses keep resolving, and the crate that
// asserts the SQL matches its own state machines carries the bytes it asserts
// against. See `xtask/src/schema.rs` for why a constant and not `include_str!`.
