# Assay-Runner Reference

> **Status:** Assay-Runner is an internal measured-run subsystem of Assay,
> now split into extraction-ready Rust crates (`assay-runner-schema`,
> `assay-runner-core`, `assay-runner-linux`) — all `publish = false` —
> plus the `runner-fixtures/` package tree (Node fixture marked
> `"private": true`; Python fixture has no distribution surface).
> Everything stays inside this repository. Not a standalone product.
> No release commitment. The extraction question is gated by the
> [Phase 2D consolidation audit](phase-2d-consolidation-audit.md).

Internal reference material for the Assay-Runner measured-run candidate.

Assay-Runner is not a released product surface yet. These references freeze
the Phase 2A internal contracts needed to keep the delegated Linux/eBPF proof
reviewable while the runner boundary is consolidated, then anchor the first
Phase 2B capability-diff planning slice.
