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.
• Meeting Context V1 YAML scaffold, generic template and documentation for manually maintained meeting metadata.
• Meeting Context V1 loader, validator, deterministic prompt representation, optional --meeting-context extraction CLI integration and extraction context provenance.
• PyYAML project dependency for Meeting Context YAML loading.
• Focused Gold scenarios for responsibility attribution and explicit position extraction.

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.
• Shared extraction prompt assembly now loads common.md, decisions.md and todos.md.
• Added explicit action-item responsibility attribution rules and clarified the decision/todo boundary, including duplicate-classification handling.
• Marked Meeting Context integration with later pipeline stages as planned while extraction-stage integration is implemented.

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.
