What to build

Collect targeted current-repo and VS Code sparse evidence for the QualifiedName candidate-producer on-demand routing residual. This issue is not a full benchmark and must not run agent A/B or a full scoreboard. It should produce enough evidence to decide whether QualifiedName routing can be kept, no-goed, or escalated to architecture.

Acceptance criteria

• Current-repo targeted profile evidence is recorded.
• VS Code sparse targeted evidence is recorded when /private/tmp/codegraph-corpus/vscode-sparse exists and is a Git checkout.
• If VS Code sparse is unavailable, the artifact records human setup needed and does not clone automatically.
• Evidence includes candidateProtocol.rustCandidateProducer.routing.active, activeShapes, onDemandLookupShapeCounts.QualifiedName, mismatch count/samples, fallback reason, fallback taxonomy, graph-readable status, and RSS or unavailable reason.
• No full scoreboard or agent A/B is run.

Completed targeted QualifiedName routing evidence.

Artifacts:

• docs/benchmarks/2026-06-22-qualifiedname-routing-current.profile.json
• docs/benchmarks/2026-06-22-qualifiedname-routing-vscode-sparse.profile.json
• docs/benchmarks/2026-06-22-qualifiedname-routing-residual-evidence.md

Current repo: QualifiedName on-demand lookups = 21, mismatch count = 0.
VS Code sparse: QualifiedName on-demand lookups = 40, mismatch count = 0.

Both runs preserved graph-readable rust-hybrid status. RSS is recorded as unavailable because these targeted CLI runs did not enable process-tree RSS sampling.
