 ### Documentation
 
+- Clarify the stable v1 support baseline and canonical installation command,
+  expose support and vulnerability-reporting entry points, and correct the
+  security advisory repository identity.
+- Record the latest Go releases-feed digest as behavior-neutral after
+  re-verifying every pinned Go 1.26.6 source and contract binding.
 - Preserve the reviewed Go release and RFC 9110 errata dispositions in an
   append-only upstream authority history.
 - Make the [specification decision register](docs/specification-decisions.md)

+The current feed retains Go 1.27.1 and Go 1.26.8 as its newest stable patch
+releases, matching the versions classified in the previous review. The prior
+response body was not retained, so this review cannot attribute the byte-level
+feed change to a specific archived download entry. Three consecutive current
+responses were byte-identical.
+
+The Go 1.26.6 feed entry still identifies `go1.26.6.src.tar.gz` with SHA-256
+`a0721c54c688901448d77ad9b3ec7ea7c474730755ff891382e92ecb93ff2cb1`,
+which matches the pinned source archive in `manifest.tsv`. The monitored
+`server.go`, `request.go`, and `url.go` bytes were independently re-fetched
+from the immutable `go1.26.6` tag and continue to match their recorded hashes.
+The selected source, minimum supported Go version, decisions, and executable
+evidence therefore remain unchanged.
