Baselines And Curves

The generated curve report has 23 rows over anchored-federation, naive-fedavg. Phase 2 baseline coverage is partial: the generated table includes only completed, hash-bound public runs. Blocked comparisons: local-only, centralized-pooled, fork-a. Blocked rows must not be described as completed comparisons.

Claim Boundaries

• Engineering-scale evidence: published SO-100 participant silos, a GPU-backed three-round federated JEPA-style run, downstream synthetic planning eval, and a matched lambda_anc=0 control.
• Does not claim paper-scale LeWorldModel performance, SO-100 task success, broad robotics generalization, or completed RFC-0006 cryptographic contribution proofs.
• Baseline coverage is partial; blocked comparisons remain blocked until matched public runs exist.

Known Gaps

• local-only: No matched local-only Phase 2 SO-100 run is published for the same silos, seed, model size, and eval budget.
• centralized-pooled: No centralized/pooled run is published; pooling these participant silos was not executed for this artifact.
• fork-a: The RFC-0005 Fork-A safe-degrade baseline has not been run on the Phase 2 SO-100 silos.
