Slim model

Slim fixture: tibetan-ocr-mic

A 0.5M-parameter fixture for the PaddleOCR-VL MIC, covering BDRC/tibetan-ocr. It is a test artifact, not a usable model, tagged test-artifact to keep it out of candidate-model search.

• Fixture key dd50d80ac1a7. It covers every checkpoint whose processor files are byte-identical and whose config matches after shrinking.
• Same architecture, smaller config: PaddleOCRVLForConditionalGeneration, shrunk by the generic rule in sweep.py (text num_hidden_layers 2, vision num_hidden_layers 2).
• Processor files copied byte for byte from BDRC/tibetan-ocr: chat_template.jinja, dry_logits_processor.py, generation_config.json, processor_config.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: pixel_values:halve, 0.164), 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 BDRC/tibetan-ocr 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 tibetan-ocr-mic.
