| """ActionProof demo (HF ZeroGPU Space). Spec §21. | |
| Tab "Live": pick a task and a fault; two policies (default: RFT baseline vs GRPO+PCSTR) run the | |
| same episode in identical environments. Each write shows what the tool CLAIMED next to what the | |
| database ACTUALLY holds; the panel scores the episode under every reward, so a transcript-trusting | |
| reward visibly pays for a false "completed". | |
| Tab "Leaderboard": all permitted Cohere models on ActionProof-Bench. | |
| Tab "Findings": headline results. | |
| Falls back to cached replays (demo/replays) when no GPU is available. | |
