gliner-datause-displacement-probe
Frozen-encoder probe of rafmacalaba/gliner-datause-displacement. The binary DATA_MENTION fine-tune
absorbed the Luna v2.3 keep/drop boundary into the encoder embeddings; a small
MLP head on [start; end; mean; 卤64-token window] span features reads it off the frozen
representation.
