# Changelog

## Unreleased

### Added

- Initial Meeting Lab project structure with source, docs, prompts, samples and
  tests directories.
- Deterministic transcript normalization module.
- Technical transcript chunking with block-aligned chunk generation.
- Whisper JSON cleanup support.
- Local Ollama-based chunk extraction flow.
- Interim Markdown meeting protocol builder for technical validation.
- Initial and windowed topic segmentation prototypes plus review tooling.
- Gold Standard extraction corpus and gold-test runner.
- Prompt loading support and common/decision prompt baseline.
- Output-view architecture documentation for Canonical Meeting Knowledge,
  Working Protocol / Arbeitsprotokoll, Distribution Protocol /
  Verteilerprotokoll and Knowledge Objects / Wissensdatenbankeintrag.
- Working Protocol Synthesizer V0 benchmark artifact for future
  canonicalizer/consolidator comparisons.

### Changed

- Refined the architecture from a single meeting protocol toward Canonical
  Meeting Knowledge as the planned semantic source of truth.
- Clarified that Working Protocol, Distribution Protocol and Knowledge Objects
  are parallel renderings, not derived from one another.
- Documented the planned Deterministic Canonicalizer and Semantic Consolidator
  stages before Canonical Meeting Knowledge.
- Documented that rendered protocol language should normally match the source
  transcript or consolidated meeting knowledge unless explicitly requested
  otherwise.
- Updated decision extraction semantics to include explicit process decisions
  and deferrals.
- Simplified extraction prompt assembly around prompt files.

### Fixed

- Fixed Whisper JSON chunk extraction to prefer `segments[*].text` over the
  aggregate top-level `text` field.
- Added chunking tests to ensure chunks do not duplicate later blocks when no
  overlap is requested.
- Added parser handling for model responses that contain thinking text before
  the final JSON object.

### Documentation

- Added architecture, pipeline and data-model documentation.
- Added output-view documentation.
- Added Gold Standard prompt-engineering methodology.
- Added formal decision-definition documentation.
- Added scenario README files for the Gold Standard corpus.
