Whether to merge native Antigravity settings and MCP servers into writable files during activation. This does not support the legacy Gemini CLI configuration or a Gemini CLI package. Gemini CLI supports a separate read-only system settings layer via GEMINI_CLI_SYSTEM_SETTINGS_PATH instead.
Declared values, including permission arrays, take precedence over existing values. Unset permission lists preserve saved grants; an explicit list replaces the saved list, including an empty list. MCP files accept comments and trailing commas, but are written as JSON without comments or original formatting. Removing a declaration does not remove it from the file. Switching back to immutable settings only removes byte-identical files; changed files require backup or removal.
