Summary

Enable google/gemma-4-12b (base) through the existing hf_gemma4_mm adapter, document its support, and promote both gemma4_base and gemma4_mm from non-blocking (xfail) to CI-gating after successful validation.

Files Changed

  • hf_adapters/hf_gemma4_mm.py – Documented support for both base and instruct Gemma 4 checkpoints.
  • tests/model_registry.py – Clarified base model routing, renamed display name, and removed non-blocking (xfail) status.
  • ARCHITECTURE.md – Added Gemma 4 12B Base to verified checkpoints and updated validation results.

Test Results

  • google/gemma-4-12b: All adapter, load, smoke, and token comparison tests passed (5/5 top-1).
  • google/gemma-4-12B-it: VLM validation passed (5/5 top-1, cosine ≥ 0.998, byte-identical caption).
  • ✅ Adapter coverage: 3/3 tests passed.

@35Upesh Gemma4 CI tests are failing, this is (at least in part) a recent regression (#261)
