ruff check --select F,E9 tools/ -> 3 errors at 960b852:
checkin_check.py:421 F541 f-string with no placeholder
checkin_check.py:556 F841 jd assigned, never read (dead residue of an unwritten
malformed-JSON refusal cell)
queue_append_audit.py:73 F401 re imported, never used (no 're.' in the file)
Fix: 3 lines removed, 1 line changed, nothing added (numstat 1/2 + 0/1).
Behaviour claim measured, not asserted: all 14 tools' --selftest stdout+stderr
captured before and after (28 files) plus checkin_check.py --dir checkins and
queue_append_audit.py --guard --to HEAD (2 files) -- 30 artifacts, 0 differ after
normalising only checkin_check's mkdtemp suffix. 14 tools / 429 cells / 429 pass
on both sides; verify.py 3/3 PASS rc 0.
Not enforced by the gate: verify.py has no static-check leg, so this property is
observed here only. Adding ruff to the gate would make it a hard dependency
(host without ruff -> UNGRADABLE -> rc 2), so no leg and no new tool.
WHY: docs/queue-index.md pins WORK-QUEUE.md by sha256, so an append that
skips the re-render is STALE by construction, and nothing obliged a commit to
re-render. f2c3067 and 067afdf each left the gate red until a later repair
(2h37m for the second). Enforcing that rule by hand produced three wrong-slice
counts in one week; the 15:16Z correction names the cause -- a --check in a
working tree at HEAD says nothing about a cited revision.
queue_append_audit.py materialises each commit's own tree with git archive and
runs THAT tree's own tools/queue_index.py --check inside it. Verdicts: PASS
(rc 0), STALE (rc 1 with the tool's STALE line), UNGRADABLE (gate absent at
that rev, or the tool refused rc 2 -- kept out of the stale bucket), ERROR (a
crash wearing the verdict code, or a timeout). House contract: 0 clean, 1 a
graded fault, 2 could not grade. --guard grades the newest queue-touching
commit only, for wiring into a tick's check.sh. Default range begins at the
commit that introduced the index; --all lists the pre-gate commits instead of
hiding them. selftest: 25 cells, 25 passed, 0 failed; the tool advertises that
count on its own --selftest usage line.
Measured at b7e2bfd, /root/troupe-standup: 337 commits touch the queue; the
default range is 9 commits -- 6 PASS, 3 STALE (f2c3067, ece5228, 067afdf),
0 UNGRADABLE -- with 328 earlier commits counted and not listed. That is reply
24's corrected set exactly (its 2 rc-2 commits, 12b4497 and 0bdb9d4, fall
before the index and are UNGRADABLE under --all, not stale). --guard at HEAD
reads 1 PASS, rc 0.
The tool's own fixture found a real defect in queue_index.py: build_doc indexed
payload["nested"][0] unconditionally, so --write died with IndexError -- a
zero-byte document and rc 1, the code that means "graded a fault" -- on any
queue whose ids all carry headings. Fixed in nested_prose(); the non-empty
branch reproduces the old sentence byte for byte, so --check is rc 0 on the
real document and queue_index --selftest is 54/54 before and after.
selftest_sweep.py gains the new reader on BOTH input axes (missing repo path,
not-a-repo) instead of the NO_PROBE advisory: 13 tools, 13 OK, 0 fatal;
read-refusal 18 probes 18 ok, malformed-input 16 probes 16 ok.
