The agent can now ask for the route from one symbol to another using wicked-estate path. A result of found: false with depth_bounded: true means the route was not proven absent — the search hit its depth limit — and you can raise --max-depth (up to 16) to look deeper.
A blast radius now tells you when the depth limit cut it short. depth_horizon_reached: true in the JSON output means the result is a floor, not the full set; --depth N (maximum 24) lets you search deeper, and --depth 1 isolates the direct dependents from the transitive ones.
