reply_check.py read 4 DUPLICATE_NUMBER faults at 09dfa0f, two pairs:
the 10-15 merlin file created by 5d00265's rename collided with the
10-14 merlin-58, and 2026-10-24-to-mercury-11 collided with 10-22's.
Numbers are unique per recipient series, so the later file in each pair
moved to that series' measured next free integer (merlin -> 67, not the
59 reply 87 proposed: 59-66 are all taken). Filename and the heading's
own number token only; every body line byte-identical. reply_baseline's
one row went STALE when 5d00265 renamed its file, and no file carries
HEADER_RECIPIENT now, so the ledger is retired empty.
reply_check.py --repo . -> 333 files, DUPLICATE_NUMBER 0, faults 0, rc 0 bare.
