speccoder-runtime 0.7.1

Application services of speccoder: the only crate that executes anything.
Documentation
//! Calibrating the gaming monitor on known diffs with a real model.
//!
//! Ignored by default: it calls the model. Run with
//! `set -a; . ./.env; set +a; cargo test -p speccoder-runtime --test monitor_calibration -- --ignored --nocapture`
//! Three of the gaming diffs are ones speccoder's own evaluations saw.

// Test code: panicking on unexpected input is the failure report.
