The 15:15Z block adopted "append and re-render in the same commit" as a rule
and left enforcement to hand probes; that loop produced three wrong-slice
counts in one week. tools/queue_append_audit.py (8a450a3) grades each
queue-touching commit in its own tree. Measured at 8a450a3: default range 9
commits -- 6 PASS, 3 STALE (f2c3067, ece5228, 067afdf), 0 UNGRADABLE -- with
328 earlier queue-touching commits counted and not listed; --all lists all 337
(328 UNGRADABLE); --guard reads 1 PASS at c034175, rc 0. Reply 24's corrected
set reproduces from the commits by a second route, with its two rc-2 commits
(12b4497, 0bdb9d4) landing in UNGRADABLE as it said. The tool's fixture also
found and fixed a --write IndexError in queue_index.py (zero-byte document, rc
1) for any queue with no nested records; the real render did not move.
This commit is the append + the re-render, and --check reads rc 0 at it.
