package:dedupe v0.1.0

• Initial release of pkg:dedupe:
  • Token-level and structural clone detection across Dart and Flutter codebases.
  • Polynomial rolling hash k-gram indexing and maximal clone extension.
  • Granular normalization filters (--ignore-comments, --ignore-literals, --ignore-identifiers).
  • Persistent content-hashed disk caching (--cache, --cache-dir, --clear-cache).
  • Exact line-union overlapping clone cluster deduplication and net lines saved analysis.
  • Linear adjacent chaining and MinHash token verification for large-scale clone clusters (>50 instances).
  • Git diff integration and PR delta scanning (--git-diff, --only-changed).
  • Multi-format report generation: Markdown, JSON, GitHub Actions annotations/summaries, and terminal text.
  • Per-file duplication metrics, cluster classification, and estimated lines saved analysis.
  • Value-semantic, immutable report models (CloneInstance, DuplicateCluster, DedupeReport) with full JSON serialization.
  • CLI binary entrypoint (bin/dedupe.dart).
