Read the mesh's comment verdicts as approvals, and warn on no fix timed from the log (issue 403, review 69)

The forge refuses an approval of one's own pull request, so the independent
reviews are comment reviews opening with "Verdict: approve at <sha>"; read
only APPROVED, the review phase was never measured. A fix whose start was
read back from the log was fixed before fix times were measured: it is kept
and shown, never warned on. A carried value at fixing after one at diagnosing
starts at its worker's active (the move), not its since (the diagnosis).
