v0.2.0

Changelog

0.2.0 - 2026-05-01

Added

• Typed JSON/export boundary with %ProgramFacts.Manifest{}.
• Typed manifest fact payloads under %ProgramFacts.Fact.*{} for function ids, call edges, effects, data-flow refs, data flows, branches, branch calls, and source locations.
• Manifest decoding with ProgramFacts.Manifest.decode!/1 and ProgramFacts.Manifest.from_map!/1.
• Corpus failure metadata with %ProgramFacts.Corpus.Failure{} and JSON decoding helpers.
• Fact conversion contracts with ProgramFacts.Facts.normalize/1 and ProgramFacts.Facts.to_manifest/1.
• Feedback search scoring modes backed by graph metrics.
• Shrinking support for options, transforms, isolated modules, and failure promotion metadata.
• Analyzer adapter, differential comparison, and metamorphic comparison APIs.
• Optional libgraph helpers for call/module/architecture graph validation.
• Additional generator policies for data flow, branches, effects, OTP, richer syntax, and architecture fixtures.
• GitHub Actions CI plus strict local mix ci checks including Credo, ExDNA, Dialyzer, and ExSlop.

Changed

• ProgramFacts now targets 0.2.0 and treats manifests as typed structs at the JSON boundary.
• ProgramFacts.to_map/1 returns atom-keyed Elixir data; ProgramFacts.to_json!/1 delegates JSON key encoding to Elixir's JSON protocol.
• Corpus manifest loaders now return %ProgramFacts.Manifest{} instead of raw decoded JSON maps.
• Public ExUnit helpers now fail with ExUnit.AssertionError for better test output.
• Core %ProgramFacts.Facts{} remains tuple/map-compatible for generator, transform, shrinker, and analyzer assertions while manifest facts are typed.

Fixed

• Avoided mixed atom/string-key metadata contracts in failure manifests.
• Tightened generated project path safety against traversal and absolute paths.
• Updated transform metadata/facts so branch-changing transforms no longer claim branch preservation.
• Fixed StreamData option support and zero-iteration search behavior.
