Slim fixture: Phi-3.5-mini-instruct-mic

A 4.2M-parameter fixture for the Phi3 MIC, covering microsoft/Phi-3.5-mini-instruct. It is a test artifact, not a usable model, tagged test-artifact to keep it out of candidate-model search.

• Fixture key e7b3e508a42a. It covers every checkpoint whose processor files are byte-identical and whose config matches after shrinking.
• Same architecture, smaller config: Phi3ForCausalLM, shrunk by the generic rule in sweep.py (num_hidden_layers 2).
• Processor files copied byte for byte from microsoft/Phi-3.5-mini-instruct: CODE_OF_CONDUCT.md, LICENSE, NOTICE.md, SECURITY.md, added_tokens.json, configuration_phi3.py, data_summary_card.md, generation_config.json, modeling_phi3.py, sample_finetune.py, special_tokens_map.json, tokenizer.json, tokenizer.model, tokenizer_config.json.
• Random weights (seed 17). They passed the input-sensitivity gate: every perturbation of the contract's inputs moved the logits by at least 0.001 (weakest: attention_mask:all_ones, 0.362), so no training was needed.
• Same tensor names as the real checkpoint. The real checkpoint has every parameter, and so does the fixture.
• Saved in bfloat16, the dtype microsoft/Phi-3.5-mini-instruct loads in by default.
• Finite in float32, bfloat16, and float16 (forward, loss, gradients).

Built by build_fixtures.py; build.json records the pinned sources, gate results, and file hashes. This repository includes the slim weights, usage and framework expectations; rebuild the other files with python example/build_fixtures.py --fixture Phi-3.5-mini-instruct-mic.
