GPU Validation Closure Report

Scope

• Full GPU-capable API coverage (inference, async jobs, runtime/model control, observability).
• Run-scoped artifact policy with post-run cleanup, preserving original data.

Run Sequence

• gpu_validation_20260228_124906 (existing backend): 44/49 passed, 5 failed.
• gpu_validation_20260228_125330 (clean 8010 backend): 48/49 passed, 1 failed.
• gpu_validation_20260228_130032 (after fix): 49/49 passed.

Final Result

• Final closure run: gpu_validation_20260228_130032
• Passed: 49 / 49
• control: 8/8 passed
• inference: 18/18 passed
• jobs: 16/16 passed
• observability: 3/3 passed
• setup: 4/4 passed

Defect Found and Fixed

• Issue: POST /agent_mining/jobs returned 500 due incompatible call signature in classifier helper.
• Root cause: _load_clip_head_from_classifier_impl(...) called infer_clip_model_fn(embedding_dim, active_name) positionally, but _infer_clip_model_from_embedding_dim_impl required keyword-only active_name.
• Fix: relaxed helper signature to accept positional second argument.
• Code refs: services/classifier.py, tests/test_classifier_infer_clip_model_signature.py.
