Rerunning Argon on Antigravity Harness lifts it past Astra, near Opus 5.5

Evaluators found Gemini 4 Argon was underrated: trace audits revealed the Pi Harness simply ended the run whenever it hit a fallback (e.g. on security tasks) in about 20% of runs. Rerun on the Antigravity Harness, Argon beats Astra and sits right behind Opus 5.5 — a reminder that harness choice can swing benchmark results significantly.
