What to build

Confirm the exact QualifiedName candidate-producer routing surface already present in code and turn it into an auditable resolver semantic residual contract. This issue should prevent accidental broad resolver implementation: the slice is evidence-only by default, and production code may change only for narrow diagnostic or test support.

Acceptance criteria

• A baseline artifact records current QualifiedName routing behavior and diagnostics.
• The artifact explicitly lists out-of-scope semantic changes: target selection, edge kind semantics, confidence, resolved-by semantics, package resolution, framework post-extract migration, dynamic-dispatch migration, schema changes, and broad disambiguation.
• Required evidence fields are listed, including onDemandLookupShapeCounts.QualifiedName, mismatch count/samples, fallback taxonomy, graph-readable status, and RSS or unavailable reason.
• Keep/no-go/needs-architecture gates are clear enough for an AFK agent.

Completed the QualifiedName residual baseline and audit contract.

Artifact: docs/benchmarks/2026-06-22-qualifiedname-routing-residual-baseline.md.

Summary: QualifiedName candidate-producer routing is already implemented as a guarded on-demand shape. The audit is evidence-only by default and explicitly excludes target selection changes, edge kind semantics changes, confidence/resolved-by changes, package resolution, framework post-extract migration, dynamic-dispatch migration, schema changes, and broad disambiguation.
