ctr-act-scan-object-ctr-noidle-e629-100k-training-state

• Experiment E629: Q4-A Scan Object ACT CTR without IdleMask, step 100000
• Full original checkpoint incl. optimizer/training state for resumption (source /root/autodl-tmp/ctr-q4a-20260921/E629/train/checkpoints/100000)
• Inference weights are also published at Shiki42/ctr-act-scan-object-ctr-noidle-e629-100k

Archival identity and evaluation version mapping (2026-10-05)

Scientific weights/configuration/actual normalization unchanged. E607 original central Experiment record unchanged. The historical inference revision below remains the weights identity. Only evaluation bindings for this exact step/revision are listed; unresolved receipt references stay explicit.
