Problem
A linked parent directory can redirect a generated changelog write outside its intended checkout. Checking only the final filename does not establish destination ownership.
Proposal
Validate real destination parents before planning any changelog read or replacement.
Acceptance criteria
Linked plugin parents and destinations refuse the complete batch without changing external or checkout files; ordinary multi-plugin writes remain atomic.
Reproduced offline against freshly fetched main using synthetic fixtures. No inspected source was executed and no provider experiment was launched. Size: S.
Part of #101.
