Antigravity changes to Gemini 4 Argon late on October 13 without changing permission posture. The locked model becomes Gemini 4 Argon (High), with settings, shell guard, NTM template, manifest and readiness expectations moved together. The wrapper strips caller --effort alongside model overrides. Its permission bypass, terminal sandbox and workspace-access policies do not change. The follow-up repairs documentation that had retroactively renamed a historical full E2E; it does not claim that old E2E ran on Argon. No capability benchmark or independent provider run was established.

Channel: main-unreleased. Half: both. Date: 2026-10-13.

Operator consequence: Stable evaluations stay on the old locked model; main evaluations need model-specific acceptance and cannot treat the older complete E2E as qualification for Argon. Do not extend the morning model snapshot to the whole UTC window.
