+## Quality harness update

+- Added `requirements-dev.txt` with pytest and wired GitHub Actions to run unit tests plus ontology validation.
+- Added `requirements-ml.txt` for the optional scikit-learn baseline dependency so CI stays lightweight.
+- Added `tests/test_dataset_validator.py` and `scripts/validate/validate_dataset.py` to validate generated main and hard-negative JSONL drafts locally. Dataset artifacts remain excluded from Git, so CI uses small synthetic fixtures; the full local datasets were also checked directly.
+- Latest checks: 8 pytest tests passed; ontology validation passed (40 concepts, 40 relations, 80 lexical mappings); main draft passed (1,000 rows, balanced 10 intents × 4 languages, 840/80/80 group-safe splits); hard-negative draft passed (80 rows).

 ## Completed
 
 - Expanded the hospitality ontology from 4 to 20 intents, with department/action relations and TR/EN/DE/RU lexical mappings.

 - Generated a separate 80-record hard-negative challenge set (10 contrast pairs × 2 examples × 4 languages); labels were checked by EVREN. It is marked `hard_negative_eval`, unreviewed, and training-disabled.
 - Ran a development-only word/character TF-IDF + LinearSVC baseline: test accuracy 0.988, macro-F1 0.987; hard-negative foil accuracy 0.613. These synthetic-pilot metrics are not publishable benchmark claims.
 - Basic email and phone-pattern screening found no matches. This does not replace full privacy review.
-- Created an EVREN API key limited to selected generation and validation models, stored in ignored local `.env` and Windows user environment; accepted EVREN LLM Gateway terms v1 after user approval.
+- Configured an EVREN API key locally for selected generation and validation models; the key itself is not stored in this repository. Accepted EVREN LLM Gateway terms v1 after user approval.
 - Uploaded the final full draft and reports to the public Hugging Face dataset repository `badblli/HOSIA-Intent` (commit `f9391a7e188367ec63c9eb858d6d0ac24f6b5f43`). The superseded pilot and partial JSONL files were removed from the main branch to avoid duplicate ingestion; they remain in commit history.
