MIC: BERT fill-mask

Model integration contract (MIC) for one usage path, across the checkpoints that share it. This repository holds the contract code and the manifest; each framework keeps its own expected results and pins this repository by revision. The model repositories are unchanged. It is a test artifact, not a model: exclude it from model search.

Usage path: AutoTokenizer + AutoModelForMaskedLM, batched, right padding.

File	What it is
integration.json	Manifest: checkpoints, which fixture covers each, frameworks, entry points, variants, unsupported targets, comparison rules
integrations/transformers/usage.md	Transformers contract, written as doc-builder runnable markdown: the same blocks are documentation and test

Checkpoint	Slim fixture (every framework PR)
google-bert/bert-base-uncased	hf-internal-testing/proto-bert-base-uncased-slim

Checked outputs: predicted_tokens, predicted_text, answer_logits, training.loss, training.gradients, training.updated.

A fixture pass and a real-checkpoint pass have different scopes; either establishes agreement on fixed inputs and a recorded runtime, not correctness on arbitrary inputs.
