+# Dead code and obsolete functionality audit
+
+Reviewed baseline: `083bc83` on `main`. The review considered supported public
+facades and CLI commands, internal package callers, tests and benchmarks,
+maintained examples, documented decisions, and build-specific uses. Public
+symbols were not classified as unused merely because this repository does not
+call them. No production code or tests were changed.
+
+The local code graph and a source reference scan identified candidates, which
+were checked against current source and documentation. The graph contained a
+stale build-function entry and excluded `internal/build` during indexing, so
+its reachability results were not treated as conclusive. The scan is a
+candidate-finding aid rather than a proof of whole-program reachability.
+`go vet ./...` and the compiled public API/dependency-boundary check passed
+offline. No dedicated dead-code analyzer was installed.
+
+## 1. Committed-selection identity wrapper has no callers
+
+**Relevant code:** [FromCommittedSelection](../../../internal/releaseidentity/identity.go).
+The repository contains no call or function-value reference to this exported
+internal wrapper, including in tests and maintained examples. It creates a
+committed-path resolver and delegates to the private `fromCommittedSelection`.
+The live `FromCommitted` path calls that private function directly with the
+resolver it already used to select the directory. The independently used
+`ResolveCommittedSelection` serves the CLI's asset-directory selection and
+must not be confused with the unused wrapper.
+
+Because Go's `internal` import restriction prevents ordinary external consumers
+from importing this package, this is not a root-facade compatibility removal.
+No documented retention or future use was found. Consider removing only the
+unused wrapper after confirming that no maintained in-tree integration needs
+it. Preserve the private implementation and the live selection APIs; the
+wrapper's absence does not imply that committed identity derivation is dead.
+
+## 2. Local tag inspection helper is used only by its own test
+
+**Relevant code:** [InspectLocalTag](../../../internal/git/tag.go), its only
+call in [TestTagOperationsAcceptFullSlashContainingRefs](../../../internal/git/source_test.go),
+and the live local guard in [candidate.Recheck](../../../internal/candidate/check.go).
+
+The helper checks that a local ref identifies the captured annotated tag
+object, but no production caller invokes it. `candidate.Recheck` independently
+performs the corresponding object-ID and type checks before publication. The
+test calls the helper directly and then separately inspects the tagged source;
+the public publication guard is exercised through the candidate and
+publication tests. The helper is in an internal package, not the supported Go
+facade. No documented reason to retain this separate test-only path was found.
+
+Consider removing the unused helper and its direct test call while retaining
+the test's full-tag and source assertions and the live publication-guard
+coverage. Alternatively, evaluate using the existing helper in the live guard
+as part of the [shared Git inspection work](10-equivalence.md#1-source-state-observations-are-independently-implemented),
+provided error behavior, guard timing, and the exact captured-object check are
+preserved. Do not remove the live guard merely because the duplicate is unused.
+
+The `CandidateTree` accessors and root-scope constructor are also used by tests
+or benchmarks, but those uses exercise meaningful tree behavior; this review
+does not recommend removing them solely because production uses a different
+entry point.
