Panoptes

Ink detection checkpoints from the ScrollAgent pipeline studies of October 2026, kept public because the article uses them as evidence of what worked and what did not: training on three scrolls at full and at rule-stopped steps, the label pair (our corrected labels against the Reader v2 labels), the learned label offset, and the Reader V3 stage. thin80 is the core AUC of the private bench files named in each row, on unit w060, and minus_rv2_thin80 its difference to the published Reader v2 on the same unit. Each model has a card under cards/ and its checkpoints under ///; internal tags and folder paths are unchanged.
