Every commit that reaches the default branch must be signed; a ruleset refuses
unsigned pushes. Estate policy:

Security Misconfiguration

Reachability: External
Exploitability: Moderate
CWE: CWE-693

Correct the rebase-merge statement. The active ruleset includes required_signatures, but it also allows merge, squash, and rebase. Replace the claim that rebase-merge is disabled with the policy requirement.

Suggested wording 
-  Rebase-merge replays commits unsigned and is disabled.
+  Rebase-merge is allowed by the repository ruleset. Use squash-merge to
+  follow the estate policy.

Review comment at @CONTRIBUTING.adoc around lines 31 - 32:
Update the rebase-merge guidance in the commit-signing policy section to reflect
that the ruleset allows rebase merges while requiring signed commits; retain the
estate policy’s preference for squash merges without claiming rebase merges are
disabled.

* **People and interactive agents** sign with an SSH key registered on GitHub
as a *signing* key (`gpg.format=ssh`, `user.signingkey=<key>.pub`,
`commit.gpgsign=true`). The committer email must be verified on that account.
* **Apps, bots and workflows** never `git push` local commits. They write
through the API (`createCommitOnBranch` or the estate `signed-push` action)
so that GitHub signs each commit.
* Merge PRs with **squash**. The ruleset checks every commit on the PR branch,
not just the result, so one unsigned commit blocks the merge. Re-create such a
branch with signed commits (`git cherry-pick -S`) and open a new PR.
Rebase-merge replays commits unsigned and is disabled.
