commit 674f39115da2c35b6dc31f029b1ebc4a481c8079
Author: Hussein Awala <huss...@awala.fr>
AuthorDate: Tue Oct 27 22:03:32 2026 +0100

    Remove unused log filename template renderer (#75780)
    
    FileTaskHandler owns the active log filename rendering path. The unused 
alternative adds a second implementation and exclusive imports without a 
production or test caller.
