-Use the repository portion of the returned PR URL as `<base-repo>` (for example, `EveryInc/compound-engineering-plugin` from `https://github.com/EveryInc/compound-engineering-plugin/pull/348`).
+Derive both the host and the repository portion from the returned PR URL. Both are needed because remote URLs use the same `host` + `owner/repo` pair as the PR URL but in different shapes (HTTPS, SSH, scp-form), and any host other than `github.com` (GitHub Enterprise, self-hosted) must still match correctly. For example, from `https://github.com/EveryInc/compound-engineering-plugin/pull/348` use `github.com` as `<base-host>` and `EveryInc/compound-engineering-plugin` as `<base-repo>`. From `https://ghe.acme.com/Org/Repo/pull/12` use `ghe.acme.com` as `<base-host>` and `Org/Repo` as `<base-repo>`. Lowercase both before substituting; host and owner/repo are case-insensitive on GitHub and remote URLs may preserve user-typed casing.
 
-Then compute a local diff against the PR's base branch so re-reviews also include local fix commits and uncommitted edits. Substitute the PR base branch from metadata (shown here as `<base>`) and the PR base repository identity derived from the PR URL (shown here as `<base-repo>`). Resolve the base ref from the PR's actual base repository, not by assuming `origin` points at that repo:
