Store trigger scripts in the depot.
Currently, the trigger scripts are stored in the file system. Submitting them to the depot means they're more likely to be backed up with the other versioned files; the files are replicated; they are versioned so we can identify changes made to them, those changes are replicated.
Currently we see triggers failing because the file hasn't been manually copied to the replica, or that the files have been modified and now do slightly different things on a replica compared with the corresponding master.
