--- "mattpocock-skills": patch --- Sharpen **`wayfinder`**'s blocking rule to prefer the tracker's native dependency relationship and say why. Native blocking is essential rather than cosmetic: it renders the frontier visually in the tracker's own UI, so the human sees what's takeable at a glance without opening the map. The rule now states that preference explicitly, notes the body-convention fallback for trackers that lack native blocking, and ties the frontier to what the human picks from.
