Performance Baseline
Generated on 2026-04-02 by scripts/record_performance_baseline.py.
The full machine-readable snapshot lives in docs/performance_baseline.json.
Use scripts/diff_performance_baseline.py to compare a fresh run against that snapshot.
The default baseline table below covers the standard example corpus only. The heavier no-warm example_07 canaries remain performance-only and are tracked through targeted diffs plus the trace artifacts.
Use scripts/characterize_pair_local_search.py for the tracked no-warm sweep in docs/pair_local_characterization.json and docs/pair_local_characterization.md.
Use scripts/record_iteration_trace.py for the current seed-42 vs seed-43 negotiated-congestion attribution in docs/iteration_trace.json and docs/iteration_trace.md.

Full Counter Set
Each scenario entry in docs/performance_baseline.json records the full RouteMetrics snapshot, including cache, index, congestion, and verification counters.
These counters are currently observational only and are not enforced as CI regression gates.
The current accepted branch keeps the post-loop pair-local scratch reroute and now also narrows late negotiated reroutes to the current conflict set once all nets already reach target and only a few conflict edges remain. That keeps both no-warm example_07 seeds at 10/10/10 while reducing main-loop work before pair-local repair.
