# 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.
- Canonicalizer V1 deterministic CLI for canonicalizing chunk extraction JSON.
- Non-LLM Canonicalizer V1 tests covering ordering, validation, IDs, parsing,
source references, exact duplicates, invalid JSON and empty categories.
- Semantic Consolidator V0 CLI for conservative facts-only semantic duplicate
detection using local Ollama.
- Consolidation prompt and non-LLM tests for payload construction, grouping
validation and source fact coverage.
- Semantic Consolidator V0 benchmark report and consolidated extraction JSON.
- Gold regression scenario for responsibility attribution integrity.
### 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.
- Clarified that Semantic Consolidator V0 is implemented only for fact
duplicate detection; broader semantic synthesis and Canonical Meeting
Knowledge remain planned.
- Documented that rendered protocol language should normally match the source
transcript or consolidated meeting knowledge unless explicitly requested
otherwise.
- Added the Responsibility Attribution Invariant across extraction,
canonicalization, consolidation, Canonical Meeting Knowledge and output
views.
- 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.
