The agent patch improves lookup performance, but it changes `addedPathDSHash` semantics: it now returns an arbitrary datasource hash from a map iteration, instead of the first-added occurrence for a path. The original behavior (and gold patch) preserves first occurrence ordering, which can affect planner decisions and makes behavior potentially nondeterministic.
Code Review
The agent patch likely does not satisfy the intended change cleanly: it introduces a clear nondeterminism regression in path-to-datasource lookup and adds broader behavioral/API changes that increase failure risk beyond the targeted performance fix.
`addedPathDSHash` now returns the first key from a `map[DSHash]struct{}` iteration, which is random iteration order in Go. The original behavior depended on first insertion/order, so planner behavior can vary run-to-run when the same path is added by multiple datasources.
Lookup caches are built inside query methods (`HasRootNode`, `HasChildNode`, interface/object checks). This introduces mutation during reads and can race under concurrent planner usage, unlike eager one-time initialization.
The change adds new planner-facing interface methods and rewires multiple visitors for interface-object/entity checks, which is beyond the stated targeted optimization and raises compatibility/maintenance risk.
