T²PO on Spark — When the Training Pool Says 28/32 and Held-out Says 9/158

T²PO's two deltas on the Phase 6 ClawGym harness: mean turns 5.00 → 4.61, task_complete 154/158, but the per-assertion ceiling stays flat at 47.7%. The strongest training-side step (45) is the worst held-out checkpoint — pool saturation lies on a single Spark.

ClawGym GRPO on Spark — Closing the Loop the SFT Adapter Couldn't

Phase 5 SFT taught the agent to keep working but never to stop. 34 GRPO steps with a shaped reward unlearn the failure mode — same model, same base, same LoRA-init, but task_complete climbs 0/158 → 154/158, mean turns drop 12 → 5, and per-assertion still inches up +3.1 pp.

ClawGym on Spark — A 7B Base, A LoRA Adapter, and the +15 pp the Adapter Earned

ClawGym shipped only a .github profile, so we built the substrate ourselves — persona task synth, sandbox harness, 200-task corpus, LoRA SFT, matched-base eval. The adapter earns +3.8 pp task pass and +15.0 pp per-assertion against its own base. The diagnostic is the lift.
