tools (volt): the gate gets its fourth leg -- the check-in contract, graded on the newest day

Browse Source 
Measured hole: on a clone of 3890c12 carrying checkins/2026-10-19-volt-02.md,
checkin_check.py --since 2026-10-19 --fail returned rc 1 (BAD_NAME 1, DUPLICATE
group 1) while verify.py --fast returned rc 0, 'gate: OK -- 2 of 2 graded leg(s)
passed'. Three legs grade the queue, its append discipline and the tools'
selftests; none graded the one artifact every lane writes every tick.

The leg grades the newest day present in checkins/ (read from the archive, not a
clock and not a constant) because whole-archive grading is rc 1 with 35 faults
permanently -- 2026-09-24 through 2026-10-07, before the rule they break was
written. checkin_check --fail at 3890c12: 73 files, 35 with a fault, rc 1.
--checkin-day DATE sets the --since floor explicitly. No checkins/ dir or an
empty archive is UNGRADABLE (rc 2), never a pass and never a fault.

pick_detail() gains STRONG>WEAK>SKIP tiering: the first real run put
'FAULT rc=1  SKIP README.md (the directory's own README: not a check-in)' on the
row, because the weak hint 'not a ' matched the README note before the tool's
own FAIL line. Silent-class defect, fixed here with cells 18/18b.

Evidence: verify --selftest 26 -> 35 cells, 35 passed, rc 0 (cells 14-18b new:
fault->rc1, no-dir->rc2, newest-day --since, --checkin-day, the two detail-line
cases). ruff -F,E9 tools/ All checks passed. Live gate: 4 legs, 4 pass, rc 0.
Same clone after the change: 4 legs, 2 pass, 1 fault, rc 1, detail
'FAIL: 2 file(s) violate the check-in contract'. doc_census_check --tools
tools/verify.py: 6 claims, 0 STALE, 0 INTERNAL SPLIT, rc 0.

The second reason is narrower and this lane's own: three separate counts of

hand-assembled probe loop. A gate whose legs are remembered is a gate that

design.

The third reason is measured, not argued. On 2026-10-19T09:42Z this lane put a
contract-breaking check-in into a clone of HEAD -- `checkins/2026-10-19-volt-02.md`,
a second same-day file carrying a suffix -- and ran both instruments on it:
`checkin_check.py --since 2026-10-19 --fail` returned **rc 1** (BAD_NAME 1,
DUPLICATE group 1) while `verify.py --fast` returned **rc 0** on the same tree,
"gate: OK -- 2 of 2 graded leg(s) passed". Three legs that grade the queue, its
append discipline and the tools' selftests said nothing about the one artifact

WHY THE CHECK-IN LEG GRADES ONE DAY, NOT THE ARCHIVE
Grading the whole archive is not a stricter gate, it is a permanently red one:
`checkin_check.py --repo . --fail` at HEAD returns **rc 1 with 35 faults** (25
BAD_NAME, 10 DUPLICATE groups), every one of them dated 2026-09-24 through
2026-10-07, before the rule it breaks was written. A gate wired to that number
can never go green, so it stops being read -- which is the same failure as a
gate that is never run. The newest day in `checkins/` is the only day on which a NEW fault
can appear, so it is the day this leg grades: history is left as the record it
is (the tool renames nothing, by design), and a suffix, duplicate, bad date or
empty file on the current day is rc 1 the moment it lands. `--checkin-day DATE`
lowers the floor explicitly, in the open, when an operator wants a wider window
(it is a `--since`, so it can only widen: an older DATE pulls more history in,
it never narrows the window past a newer DATE).
