-The historical cards record their internal development versions (`v240` and `v966`) as provenance, but those numbers are intentionally not used in the public repository names. The Before checkpoint is already a historically trained v240 state, not an untrained initial state; the playback was not held out and retained task-triggered PAM stimulation while plasticity was off. The v966 checkpoint belongs to a mixed older lineage. These checkpoints are **not canonical v1 evidence**.
