axiom_engine 0.5.0

//! AxiomBench — the proof layer.
//!
//! Runs the deterministic pillars (cognition, trust, fleet) always; the cost
//! pillar only with `--live`. Each pillar returns a `PillarResult`; the runner
//! prints them, writes `bench/results/<ts>.json`, and regenerates `RESULTS.md`.
//!
//! Usage: `axiombench [--live] [--out <path>]`
//!   --live         include the cost pillar (needs a running proxy + corpus)
//!   --out <path>   results JSON path (default bench/results/<unix_ts>.json)
