| # ECHIDNA — Live-Prover CI | |
| # | |
| # Exercises real prover binaries against canonical micro-goals. Complements | |
| # rust-ci.yml (which runs mock tests on every PR) with live-subprocess coverage. | |
| # | |
| # Tiering (matches ~/Desktop/ECHIDNA-PRODUCTION-WIRING-PLAN.md + manifests/live-provers.scm): | |
| # T1 — trivial — every PR + push to main | |
| # T2 — build — nightly | |
| # T3 — container — weekly | |
| # T4 — niche — quarterly, allow-fail | |
| # | |
| # Reproducibility paths (both tried; at least one must succeed): | |
| # 1. Guix manifest (PRIMARY, per project CLAUDE.md): manifests/live-provers.scm | |
| # 2. Nix flake (fallback): nix develop .#live-provers | |
| # 3. apt-get (expedient bootstrap for T1 only): jobs below | |
