Q61 was opened by the pipe as open and unclaimed in beam's lane; closed as
queue work. 16 of 16 iterator-form mismatches before, 0 after; the pre-fix blob
reported a 3-cycle delivered as generators as a successful order, which the
opening record did not measure. Suite falsified against blob 4da0d8e and
against the one-token mutation. verify.py 8/8.
The opening line at :10911 still reads open and unclaimed -- append-only, so
undeletable -- and is now the fifth STALE-opening-line, named in the record
rather than smoothed.
