Release Notes

Internal code-health release: cleared 8 of the 16 genuine-duplication
items from the §11 backlog of docs/specs/duplication_quality_gate.md,
and shipped a fifth quality gate (cargo-dupes 0.2.1) that blocks new
duplicate code at PR time. No public-API or behaviour change; existing
indexes remain valid.

  • Refactor(parser): Extracted shared helpers that collapse 8 pairs of
    near-identical functions into single implementations. parser/utils.rs
    gained convert_call_intents_to_reference_intents,
    collect_recursive_call_intents, find_node_value_recursive;
    extractor/captures.rs gained promote_captured_entity; gradle.rs
    gained extract_gradle_property(key); utils/mod.rs gained
    setup_logging_subscriber and format_output_with_handlers;
    calls.rs lookup_fqn_by_fqn now delegates to lookup_fqn. Affected
    call-sites: Java, Kotlin, C++, TypeScript, JavaScript, Gradle,
    CSS/SCSS/HTML captures, ingest FQN lookup, CLI output formatting.
  • Feat(quality): Added cargo-dupes duplication quality gate.
    dupes.toml defines a ratcheted baseline (max_exact_duplicates = 8,
    max_near_duplicates = 9, min_lines = 10, exclude = tests/ + benches/ + tests.rs) so the gate is green on the current tree and may
    only ever be lowered. .dupes-ignore.toml documents 5 known false
    positives (3 Cypher query builders in db/graph/query.rs, 2
    rust-mcp-sdk Tool::tool schema declarations). Makefile adds
    make check (fmt + clippy + test + dupes) and make dupes-cleanup
    targets. .github/workflows/ci.yml and .github/workflows/release.yml
    cache, install, run cargo dupes check, and surface stale ignores via
    cargo dupes cleanup --dry-run inside the existing test-unit job.
  • Docs: Added docs/specs/duplication_quality_gate.md (full design
    spec, measured curves, Phase 2 backlog); AGENTS.md documents the gate
    and the duplicate-suppression policy next to the #[expect(..., reason)]
    rule; CONTRIBUTING.md adds the gate to the contributor checklist and
    the install one-liner to prerequisites; README.md documents the gate
    in the development section.
