# Quality gate — granite-4.0-h-tiny (retrofit)

Applied after the fact to quants built before this repo had a quality-gate process. **Read-only**: the existing GGUFs below were not re-quantized, only tested — real generation on a fixed prompt suite, and (where a working chat template exists) tool-calling reliability. This does not change what's published, only documents it honestly.
