- Around line 197-199: **Handle a vacant Deputy Project Leader office in the
GitHub owner rule.**

The first Deputy Project Leader election is scheduled for the 2027 AGM, but the
owner rule unconditionally requires a Deputy Project Leader. The three-owner
clause does not waive this named-owner requirement. Line 199 also requires a
Deputy Project Leader who is an owner to be a Security Team member, but Deputy
Project Leader status does not grant that membership automatically.

Define the owner substitute while the office is vacant:

<summary>Suggested fix</summary>

```diff
-- GitHub organisation owners must include the Project Leader, Deputy Project Leader and at least one other Security Team member.
+- GitHub organisation owners must include the Project Leader, the Deputy Project Leader when that office is filled and at least one other Security Team member.
+  When the Deputy Project Leader office is vacant, at least two other Security Team members must be owners.
  At least three human owners must be retained, including while an elected position is vacant.
```

Summary

Summary by CodeRabbit

• Documentation
  • The Security Team and its members are now listed in the README and man pages.
  • The maintainer checklist clarifies how Security Team appointments and access permissions are managed, including which roles may hold administrative access.
  • Governance documentation now requires GitHub organisation owners to include the Project Leader, Deputy Project Leader and at least one other Security Team member. It also extends Security Team administrative access requirements to GitHub.

The update-maintainers command now synchronises Security Team members into the README. Manpage generation reads and renders that roster, and the checked-in manpage documentation includes it. The governance document and maintainer checklist define Security Team appointment, ownership and access rules.

Changes: Security Team roster and access

Layer / File(s)	Summary
Security Team access rules docs/Homebrew-Governance.md, docs/New-Maintainer-Checklist.md	The documents define Security Team requirements for organisation owners and administrative access. The checklist also covers appointments and access changes when a member departs.
README roster synchronisation Library/Homebrew/dev-cmd/update-maintainers.rb, Library/Homebrew/test/dev-cmd/update-maintainers_spec.rb, README.md	The command formats Security Team members and updates the README roster. The test checks the maintainer lists.
Manpage roster rendering Library/Homebrew/manpages.rb, Library/Homebrew/manpages/brew.1.md.erb, Library/Homebrew/test/manpages_spec.rb, docs/Manpage.md, manpages/brew.1	Manpage generation reads and renders the Security Team roster. The test and checked-in manpage documentation include the team members.

Merge Risk: Moderate · up to f8919

The governance text now requires an owner set that cannot currently be met because no Deputy Project Leader exists. Make the Deputy requirement conditional on the office being filled, and define a substitute owner rule for the vacancy, before merging. The checklist wording now matches the governance scope.
