@ -3640,3 +3640,25 @@ Findings:
- The pathological `seed 43` basin is not front-loaded. It matches the solved `seed 42` path through iteration `5`, then falls into three extra iterations with only `4` completed nets and `4` conflict edges.
- The late blowup is concentrated in two nets, not the whole routing set: `net_06` contributes `31604` attributed nodes and `83752` congestion checks, while `net_03` contributes `27532` nodes and `75019` congestion checks.
- This points the next optimization work at late-iteration reroute behavior for a small subset of nets rather than another global congestion or pair-local-search change.
## Step 65 stop after fully reached two-edge plateau
Measured on 2026-04-02T16:21:02-07:00.
Findings:
- Added a narrow late-iteration stop rule: once every net already reaches target and the best snapshot is down to the final `<=2` dynamic-conflict-edge basin, stop after the first no-improvement iteration and hand off to bounded pair-local repair.
- The solved seed-42 no-warm canary improved from `6` to `5` negotiated-congestion iterations and dropped from about `1764` to `1303` nodes and from `4625` to `2921` congestion checks, while staying `10/10/10`.
- The former seed-43 pathological basin collapsed from about `50s`, `61259` nodes, and `165223` congestion checks to about `2.53s`, `1691` nodes, and `4330` congestion checks, still finishing `10/10/10`.
- Guardrails held unchanged: warmed `example_07` stayed `10/10/10`, and `example_05_orientation_stress` stayed `3/3/3`.
## Step 66 reroute only current conflict nets in late all-reached phase
Measured on 2026-04-02T16:46:00-07:00.
Findings:
- Once all nets already reach target and the live conflict graph is down to `<=3` edges, the next negotiated iteration now reroutes only the currently conflicting nets instead of all nets.
- The solved seed-42 no-warm canary stayed `10/10/10` and improved from `50` routed nets / `1303` nodes / `2921` congestion checks to `44` routed nets / `1258` nodes / `2736` congestion checks.
- The seed-43 no-warm canary stayed `10/10/10` and improved from `60` routed nets / `1691` nodes / `4330` congestion checks to `46` routed nets / `1582` nodes / `3881` congestion checks.
- Guardrails held: warmed `example_07` stayed `10/10/10`, and `example_05_orientation_stress` stayed `3/3/3` while trimming slightly to `5` routed nets, `297` nodes, and `146` congestion checks.

## 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.
For the current accepted branch, the most important performance-only canary is `example_07_large_scale_routing_no_warm_start`, which now finishes `10/10/10` after a bounded post-loop pair-local scratch reroute. The relevant counters for that phase are:
- `pair_local_search_pairs_considered`
- `pair_local_search_attempts`
- `pair_local_search_accepts`
- `pair_local_search_nodes_expanded`
The latest tracked characterization sweep confirms there is no smaller stable pair-local smoke case under the `<=1.0s` rule, so the 10-net no-warm-start canary remains the primary regression target for this behavior.
The tracked iteration trace adds one more diagnosis target: `example_07_large_scale_routing_no_warm_start_seed43`. That seed now remains performance-only, and its blowup is concentrated in late iterations rather than the initial basin. In the current trace, seed `43` matches seed `42` through iteration `5`, then spends three extra iterations with `4` completed nets while `net_03` and `net_06` dominate both `nodes_expanded` and `congestion_check_calls`.
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.
