Under the hood

Hook-provided context entries no longer need to trace back to an earlier hook that added them

What

Hooks (scripts that run at certain points and can attach extra 'context' information) previously had their context arrays checked to ensure every entry could be traced back to something a prior hook in the chain had actually added. That lineage check has been removed. The validation now only checks that context values aren't non-list, that entries aren't empty strings, and that the total length doesn't exceed the character limit.

Why

This loosens what hook-supplied context is allowed to look like, dropping a rule that previously required an unbroken chain of attribution between hooks; the practical effect is that a hook's context is no longer rejected purely for not matching what an earlier hook passed along.
