Slim model

Slim fixture: QianfanOCR-mic

A 19.9M-parameter fixture for the QianfanOCR MIC, covering bairongz/QianfanOCR. It is a test artifact, not a usable model, tagged test-artifact to keep it out of candidate-model search.

• Fixture key c82eae46c748. It covers every checkpoint whose processor files are byte-identical and whose config matches after shrinking.
• Same architecture, smaller config: QianfanOCRForConditionalGeneration, shrunk by the generic rule in sweep.py (vision num_hidden_layers 2, text num_hidden_layers 2).
• Processor files copied byte for byte from bairongz/QianfanOCR: added_tokens.json, chat_template.jinja, generation_config.json, merges.txt, preprocessor_config.json, processor_config.json, special_tokens_map.json, tokenizer.json, tokenizer_config.json, video_preprocessor_config.json, vocab.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: pixel_values:halve, 0.0105), 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 bairongz/QianfanOCR 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 QianfanOCR-mic.
