## Summary Replace N+1 per-hop DB queries in `handleResolveHops` with O(1) lookups against the in-memory prefix map that already exists in the packet store. ## Problem Each hop in the `resolve-hops` API triggered a separate `SELECT ... LIKE ?` query against the nodes table. With 10 hops, that's 10 DB round-trips — unnecessary when `getCachedNodesAndPM()` already maintains an in-memory prefix map that can resolve hops instantly. ## Changes - **routes.go**: Replace the per-hop DB query loop with `pm.m[hopLower]` lookups from the prefix map. Convert `nodeInfo` → `HopCandidate` inline. Remove unused `rows`/`sql.Scan` code. - **store.go**: Add `InvalidateNodeCache()` method to force prefix map rebuild (needed by tests that insert nodes after store initialization). - **routes_test.go**: Give `TestResolveHopsAmbiguous` a proper store so hops resolve via the prefix map. - **resolve_context_test.go**: Call `InvalidateNodeCache()` after inserting test nodes. Fix confidence assertion — with GPS candidates and no affinity context, `resolveWithContext` correctly returns `gps_preference` (previously masked because the prefix map didn't have the test nodes). ## Complexity O(1) per hop lookup via hash map vs O(n) DB scan per hop. No hot-path impact — this endpoint is called on-demand, not in a render loop. Fixes #369 --------- Co-authored-by: you <you@example.com>
