Summary

Update network-access, Live View, replay, and security-scope pages to include both 443 and 8443 during the browser URL migration. Extend every Live View and replay CSP example to accept default-port URLs while retaining legacy sources. Tell users to use returned URLs unchanged.

Validation

  • Verified CSP source lists match across network-access, Live View, replay, and the synthetic test update in kernel/kernel#5173; HTTPS/WSS cover both wildcard domains and ports.
  • git diff --check passes.
  • Docs preview not run; documentation-only change.

Note

Low Risk
Documentation-only updates to firewall, CSP, and bug-bounty scope text with no runtime or security behavior changes in this repo.

Overview
Updates customer-facing docs for browser data-plane URLs moving to HTTPS/WSS on port 443 while 8443 remains valid during rollout.

info/network-access.mdx now lists 443 and 8443 for CDP, WebDriver BiDi, Live View, replays, and app connections, adds guidance to allow both ports and use API-returned URLs as-is, and expands Live View / replay CSP with default-port https:// / wss:// entries on *.onkernel.com and *.kernel.sh alongside the existing :8443 sources. Troubleshooting for blocked browser connections now checks both ports.

browsers/live-view.mdx and browsers/replays.mdx mirror the same CSP examples (replay embed meta tag includes port-443 wildcards).

security-vulnerability-reporting.mdx widens Tier 1 metro scope from *.kernel.sh:8443 only to *.kernel.sh:443 and :8443.
