-- ITFlow - how much billable time did system-generated replies invent?
--
-- Run these BEFORE deciding whether to correct historical data. Nothing here
-- writes; the UPDATE at the bottom is commented out on purpose.
--
-- Background: until this fix, replies ITFlow wrote itself booked time worked -
-- one minute for assignment / priority / merge / close / invoice / quote /
-- schedule / task reopen, and the task's full completion estimate for task
-- completion. That time is in ticket totals, technician and client time
-- reports, project totals and anything already invoiced.

-- 1. Total invented time, by reply kind.

-- 3. Correction, if you want it. NOT shipped as a migration: these rows are
--    editable in the UI, so some of them may carry time a technician put there
--    deliberately, and anything already invoiced should not move underneath the
--    invoice. Review the output above first, back up, then run by hand.
