Report privately via GitHub Security Advisories. Do not open a public issue.
- Gesture or navigation behavior the caller didn't wire — the layout attaches gestures (swipe-to-dismiss, divider drag) and back-interception only to the panes it owns. Any way to drive those handlers against content or navigation state the caller didn't opt into is a security report.
- Content of the panes — the package renders caller-provided builders verbatim; what they display is the app's concern.
- Overlay stacking with other packages' overlay entries — z-order interplay is a compatibility issue, not a vulnerability.
Valid reports are fixed and shipped as patch versions.
