"""Compute actual GPU cost of the reproduction from HF Job durations.

Why: the logbook's Scope & cost table must report MEASURED cost, not an
estimate. This reads each job's real total_secs from `hf jobs inspect` and
multiplies by the published flavor rate, including the failed and cancelled
jobs -- an honest cost line counts the mistakes too.
