Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughRelocated graph cache entries now retain optional cross-file extraction fields. Caller IDs follow the relocated source path, while import bindings remain unchanged. Tests cover field preservation and compare relocated snapshots with fresh extraction.

Validate optional cache fields before returning them.
A relocated cache entry can retain import_bindings with specifier: 42. When a matching raw call reaches resolveOne, resolveModule calls .startsWith on that number and the build can fail instead of re-extracting the file. Validate both optional arrays and their member fields in validateItems, then return a cache miss for malformed entries.

Summary
Fixes #415.
The content-addressed cache can reuse an extraction at a different path.
rewriteSourceFilereconstructs only the required fields and dropsraw_callsandimport_bindings, making cached and fresh graph snapshots disagree after a rename or copy.Preserve both optional fields, rewrite caller IDs to the new path, and keep relative import specifiers intact for the existing resolver. A real TypeScript extractor/cache/snapshot test compares the relocated hit with fresh extraction and verifies the new relative provider is selected.
Version Bump
No release requested. Package versions, dependencies, lockfiles and release workflows are unchanged.
Test plan
The repository-native focused tests report 2 failures and 15 passing controls on unchanged production source; the prepared correction passes all 17 focused tests. The final commit is independently validated by the full Node 22/Linux suite with coverage, typecheck, build, duplication guard and critical-only bundle audit. The workflow enforces zero failed and zero skipped tests.
Exact submitted commit:
ba3f547871bfb3f45ddd046786d8ece13ae61796. Independent Linux job, commands and logs. The checkout is pinned to this commit, not a combined patch branch.The focused tests use isolated files or source fixtures and the real parser/cache/usage code. No customer data, credentials or live model/backend calls are required.
Compatibility and limits
No cache format or invalidation-version change. Missing optional fields remain absent. This is distinct from the source-dialect cache-identity fix; both touch cache tests and require normal integration review, not a stacked dependency.
A clean full macOS suite and native Windows validation are not claimed. Upstream CI approval and maintainer review are separate from this passing independent gate.
