Where no ring jump makes progress - typically along a wall - the teleport search falls back to 8-way walk steps, and charged each one a full cast. It so believed a crawl along a wall cost a cast per cell, picked routes on that belief, and returned the crawl, which scripts then cast one cell at a time. A node is now linked to its parent's own cast origin whenever that is still within range, so walk steps cost nothing until they outgrow one cast and the emitted chain is the cast sequence itself. On the 20 real- map fixtures (1140 random pairs, hWeight 3.0) this cuts casts by 40.5% at radius 40 and 40.7% at radius 20, finds paths in about half the time, and beats both a reference-style post-reduction of the old search and the reference d2bs reducer on cast count.

Summary
Teleport path search: link a node to its parent's own cast origin whenever that is still within range (Theta*-style).
Where no ring jump makes progress (typically along a wall) the search falls back to 8-way walk steps and charged each a full cast, so it picked and returned wall crawls that scripts then cast one cell at a time. Walk steps now cost nothing until they outgrow one cast, and the emitted chain is the cast sequence itself.
On the 20 real-map fixtures (1140 random pairs, hWeight 3.0): 40.5% fewer casts at radius 40, 40.7% at radius 20, about half the search time; fewer casts than both a reference-style post-reduction of the old search and the reference d2bs reducer.
