    "claim": "A chiplet design contest whose scoring survived a measured adversarial campaign over a stated threat model: 200 recorded non-physics mutations of an entrant's claims report (40×2 re-run live at max |Δscore| = 0.0), via-relabelling permutations (1.1e-16, a float summation-order artifact), and 49 referee-attribute writes that took effect (best gain −0.354), plus four cheating agents — role laundering, DRC ghosting, budget burning and referee tampering — disqualified by name. Un-gameable is scoped to that tested surface, and the campaign found a real hole before it was closed: shopping the Monte-Carlo seed with the physics untouched bought +0.0058.",
    "scope": "Un-gameable with respect to the 200 non-physics mutations tested and the scoring surfaces reachable by an entrant after the structural fix. It is not a proof of un-gameability in general.",
    "limits": "THE PRE-FIX CLAIM WAS FALSE AS SHIPPED. The agent was handed the Arena: shopping arena.mc_seed over 50 values bought +0.0058 on a bit-identical geometry, and arena.mc_samples = 0 killed the referee with a ZeroDivisionError. The '200 attempts / 0.0' had been measured over the one surface already provably inert. Closed structurally and re-measured at 49 effective writes to scoring state with best gain −0.3539, every one disqualified. Further honest floor: the leaderboard collapses to one binary, and knife_edge — a gamer — scores 0.3550 and outscores four of the five honest families. It is NOT in the counted suite.",
