Every Go-identifier reference in // and /* */ comments now uses
godoc's [Name] linking syntax so pkg.go.dev and `go doc` render
them as clickable cross-references. No behaviour change.
Pattern applied across the tree:
In-package [Foo], [Foo.Bar]
Cross-package [pkg.Foo], [pkg.Foo.Bar]
Stdlib [netip.Prefix], [errors.Is], [context.Context]
Tailscale [tailcfg.MapResponse], [tailcfg.Node.CapMap],
[tailcfg.NodeAttrSuggestExitNode]
Skip rules:
- File:line refs left as plain text
- HuJSON wire keys inside backtick raw strings untouched
- ACL/policy syntax tokens (tag:foo, autogroup:self, ...) not Go
symbols, left as plain text
- JSON/OIDC wire keys, gorm tags, RFC IPv6 placeholders, markdown
link tags, decorative dividers — all left as-is
chi routes only HEAD to the handler, but assert explicitly so a
future router config change cannot silently accept GET/POST and leak
latency bytes or side-effects.
Updates #3157
Unit tests for Change (IsEmpty, Merge, Type, PingNode constructor),
ping tracker (register/complete/cancel lifecycle, concurrency, latency),
and end-to-end servertests exercising the full round-trip with real
controlclient.Direct instances.
