    "Exactly one final done marker per episode",
    "Rewards preserved, no success inference",
    "All 89 instructions checked against an explicit object/manipulation grammar",

Source identifiers excluded; signed zero canonicalized for comparison. Repeated individual states and repeated instructions are legitimate temporal or task information and are retained.",
  "limitations": [
    "No images: unsuitable as-is for vision-conditioned policy learning.",
    "Only one tabletop robot/environment; limited generalization evidence.",
    "No near-duplicate or domain-expert physical semantics review.",

    "Source conversion combines all episodes under train; original TFDS evaluation membership not recovered.",
    "This is a preliminary offline research package, not a validated real-robot controller."
