S016 Blocks Ranking ACT checkpoint — CTR without IdleMask

This repository contains the inference-only final checkpoint from the registered S016 E770 training run.

Training configuration

• Experiment / Run: E770 / E770-R001
• Policy: official LeRobot ACT 0.4.4
• Checkpoint: final step 100,000; batch size 8; seed 87431
• Training data: Shiki42/ctr-sortblocks-100ep-ctr at revision 9ee0f9d8e0700df5fac08454e7e213c4904d3024 (100 episodes, 68,438 frames)
• Variant: CTR without IdleMask. The registered ablation disables consumption of observation.arm_active_mask in the action loss; ordinary temporal padding remains in effect.
• CTR source commit: 335ad0e01f4cf5b9915d8e2eea00554c1c78d6ce
• LeRobot source commit: 8fff0fde7c79f23a93d845d1a50e985de01f8b8a
• Locked runtime manifest SHA-256: cdf763fd150ddc0229d3aafa3d03e4aca596e8c8be145ebacbb2b1ab1ba23f2e

Checkpoint qualification and evaluation status

A fresh-process CPU restore verified all 234 model tensors exactly and restored the processor configuration. A deterministic action was produced from a real sample from the pinned training dataset. The S016 held-out scene suite and ACT evaluation adapter are not yet qualified; this card makes no held-out success-rate or collision-rate claim.
