Antigravity: bypassPermissions mode still prompts for Edit tool calls

Summary

The Antigravity desktop app (macOS) still shows "Make this edit to SESH_NOTES.md?" permission prompts even when:

1. ~/.claude/settings.json has "defaultMode": "bypassPermissions"
2. The "Bypass permissions" UI toggle is enabled in the app

Evidence

• Session config (~/Library/Application Support/Claude/claude-code-sessions/.../local_*.json) shows permissionMode: acceptEdits even when the UI toggle sets chromePermissionMode: skip_all_permission_checks. These two values are disconnected — the toggle changes chromePermissionMode but the session's permissionMode stays at whatever defaultMode was when the session was created (or possibly the previous default).

• After changing defaultMode to bypassPermissions in settings.json and starting a new session, the prompt still appears for Edit tool calls. Screenshot shows the standard "Make this edit to X? 1 Yes / 2 No" dialog.

Expected behavior

With bypassPermissions mode (either via settings.json or UI toggle), all tool calls including Edit should execute without prompting.

Environment

• Antigravity desktop app (macOS)
• Claude Code version: 2.1.87
• macOS Darwin 25.4.0
