I'd like to take this one. The GlobalBlocking notice here is built in GlobalBlockingHooks::onSpecialContributionsBeforeMainOutput, which I recently worked on for T381236, so I'll mirror the existing mw-contributions-blocked-notice wrapper pattern for the global block notice and do the same for the lock notice in CentralAuth. Any objection?

That makes sense to me, thanks! Leaving this task open for the CentralAuth patch.

I think CheckUser-GlobalContributions has been tagged by mistake, as the task only talks about the notices shown only on Special:Contributions (Special:GlobalContributions does not display them), but please clarify if this is not the case.

@matmarex GlobalContributions does show a lock notice if the target is locked.

The fix for this likely would be outside CheckUser-GlobalContributions, but if there is feel free to tag that tag again (re-adding Product Safety and Integrity as we own GlobalBlocking)

NguoiDungKhongDinhDanh is right.

• SpecialGlobalContributions extends ContributionsSpecialPage and calls parent::execute().
• parent::execute() fires the SpecialContributionsBeforeMainOutput hook.
• The CentralAuth handler does not perform any page-specific check.
• As a result, the lock notice is also displayed on SpecialGlobalContributions.
• Change 1317483 adds the CSS class in that handler, so it applies to both pages.

The global block notice is different:

• GlobalBlocking's handler is gated by shouldShowBlockLogExtract().
• Because of that condition, the global block notice may not appear on SpecialGlobalContributions.
