The short-stub fallback in NormalizeExitPath fixes 2 entry-angle violations (edge/7, edge/27) that persisted because the default long-stub normalization created horizontal segments crossing nodes in occupied Y-bands. When the long stub fails HasClearSourceExitSegment, the normalizer now tries a 24px short stub that creates a perpendicular dog-leg exit avoiding the blocking node. Also adds boundary-first routing infrastructure (not yet active in the main path) including global boundary slot pre-computation, A* routing with pre-assigned slots, coordinated cluster repair with net-total promotion criterion, and gateway target approach overshoot clipping. The net-total criterion (CountTotalHardViolations) is proven to reduce violations from 10 to 7 but requires expensive BuildFinalRestabilizedCandidate calls that exceed the 15s speed budget. Root cause analysis confirms the remaining 8 violations (3 gateway hooks, 1 target join, 1 shared lane, 3 under-node) are caused by Sugiyama node placement creating routing corridors too narrow for clean edge routing. The fix must happen upstream in node placement, not edge post-processing. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
