docs: Observe FreeBSD router-originated ICMPv6 Time Exceeded (live root trace)#53

…ot trace) Closes the last IPv6 design-doc open item. Ran on real FreeBSD 14.3 arm64 (bridged Parallels VM, live Sonic v6): sudo ftr -6 2001:4860:4860::8888 produced a 17-hop trace with router-originated ICMPv6 Time Exceeded from every intermediate hop, destination reached, full enrichment, gateway classified LAN. google.com (19 hops) and a v4 regression also clean. Access recipe (for the record): sshpass with keyboard-interactive auth as user ftr, then sudo (not su — ftr isn't in wheel; sudo is NOPASSWD). Every supported platform's IPv6 path is now implemented AND observed on real hardware. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Closes the final IPv6 design-doc open item. Ran a live root traceroute on real FreeBSD 14.3-RELEASE arm64 (bridged Parallels VM with real Sonic global IPv6):
google.com(19 hops) and a v4 regression were also clean. This means every supported platform's IPv6 path — macOS, Linux, Windows, FreeBSD — is now implemented and observed on real hardware/kernels, not just compiled.For the record, the access recipe that worked non-interactively (after two earlier subagent stalls on interactive

Binary was v0.9.0;bsd_v6.rsis unchanged through v0.10.0.Only OpenBSD's live external trace remains deferred (its VM has no external v6); the OpenBSD build and permission gate are already validated.
