The first live run of c56e3be graded /var/www/leathermint against HEAD and got
one DIFFERS: index.html served 26,064 B / b5136bb947dd vs tree 25,697 B /
42b2f374f5d3. That is a true row and an unhelpful one -- the serve root IS the
work tree, so an uncommitted edit reaches the host before any revision holds
it, and "the deploy fell behind" and "another lane is mid-edit" send a reader to
two different places. (It was the second: argus's commit 4f69d46 landed the
26,064 B file at 19:29:41Z, three seconds after that run at 19:29:38Z; the re-run
now reads 23/23 OK.)
Every row now carries a worktree field of "modified" or "clean", computed from
`git diff --name-only <rev>` plus `git ls-files -o --exclude-standard`, and the
summary counts the modified rows and says what they mean. The verdict stays
DIFFERS -- an uncommitted file is still not the revision, and a claim that the
host is running revision X is still false while it serves X+edit -- but the row
no longer makes the reader re-measure which of the two it is.
Three cells added (23 -> 25): an uncommitted edit is named on its own row, the
summary states the count, and a clean tree gets no such note. selftest 25/25
rc 0.
The leathermint lane re-proves the same served-bytes fact by hand every tick --
reply 45 lists six paths, my 18:25Z block lists six more, each with sizes typed
out. `landing_check.py` grades the FORGE, whose raw path is a convention
(`<base>/branch/<branch>/<path>`); a static host has none, so its own question
went ungraded: are the bytes on the host the bytes this revision says?
New instrument `tools/served_drift_check.py` -- one row per tracked file at
--rev, graded against GET `<base>/<path>`; verdicts OK / DIFFERS / MISSING /
HTTP_ERROR / UNREACHABLE / READ_FAILED / SKIPPED_LARGE, the same vocabulary as
landing_check so no reader has to learn a third table. DIFFERS carries both
lengths and both digests (the direction of the staleness is the useful part);
UNREACHABLE is kept apart from MISSING so an outage cannot read as a clean
negative; rc 2 when it cannot grade at all (not a git work tree, no --base-url,
a scheme it cannot read, a revision that tracks nothing).
Self-proving: `--selftest` is 22 cells over a fixture git repo and a real
http.server on 127.0.0.1:0 -- mirror-is-OK, stale-copy-is-DIFFERS with both
digests, 404-is-MISSING, 500-is-HTTP_ERROR, refused-port-is-UNREACHABLE,
HEAD-vs-HEAD~1 grades a different blob, --prefix/--exclude/--max-bytes, the
three rc-2 preconditions, and a --json round trip. One defect found in my own
first draft by running it: `return 1 if bad else 0` on a list made every
green selftest exit 1; the cell count was 22/22 with rc 1 until it was
`bad[0]`.
Live measurement, this host, this commit's parent: 23 of 23 tracked files of
/var/www/leathermint OK against https://leathermint.alexanderwhitestone.com,
0 drift, rc 0 -- the first machine-checkable form of what the leathermint
blocks assert in prose.
Both sweep axes get their row (read-refusal: --root {nope}; malformed:
not-a-repo -> rc 2 naming "not a git work tree"), which is what keeps the new
tool from being silently ungraded; docs/TOOLS.md re-rendered in the next
commit, since tool_map reads the tree at HEAD.
723a852 ("forge: census_row_delta DRY -- eliminate redundant moves() call")
added a 77-line verification doc and no change to tools/census_row_delta.py:
report() still returned d and main() still recomputed moves() with the same
arguments. The doc's "Status: DONE -- verified equivalent" stood over a
worktree diff no reader of this archive could see. This commit lands the
two-line change itself.
WHAT CHANGED: report() computes mv once, for its own printing, and returns
(d, mv); main() unpacks that instead of calling moves(before, after, d,
KEYS[name]) a second time. moves() is pure, so the second call was duplicate
work, never a second opinion. Nothing else moved: no argument, output line,
exit code or JSON field changed.
VERIFIED ON REAL CENSUS PAIRS, NOT A FIXTURE. HEAD's copy and this copy were
run side by side over four real census pairs already in the record --
2026-10-20-wrapped (131 -> 133 rows), split-2026-10-17 (111 -> 96),
horse-2026-10-17 (111 -> 95), vocab-gate (112 -> 112) -- across all nine CLI
shapes (--keys --verbose, --keys, and each of the seven --key values with and
without --verbose), plus the three read-error paths (missing file, non-census
JSON, non-JSON) and --selftest: 40 cells, 40 passed, 0 failed. Compared per
cell: rc, stderr, stdout, and the --json payload's sha256. Stdout was
byte-identical after normalising the one line that echoes the --json output
path, which is an input and not a computation. Read-error paths return rc 2
on both sides ("cannot read census ..."), and the selftest is 33/33 on both.
THE DUPLICATION IS ACTUALLY GONE, MEASURED. Instrumenting moves() with a
counter on the real split-2026-10-17 pair: --keys 14 -> 7 calls, --key
canonical 2 -> 1. Matches the doc's claim on a live path rather than on its
synthetic pair.
ONE CORRECTION TO 723a852's FRAMING, measured. Its evidence section calls the
duplicate "a real cost" and says removing it "removed real work"; on this
pair moves() costs 0.15 ms for the canonical key and 0.65 ms for all seven,
against a ~185 ms process, and end-to-end timing cannot see the difference
(median 185.2 ms unpatched vs 197.3 ms patched over 9 runs, both inside a
154-235 ms spread). The change is landed as a cleanliness fix -- one
computation, returned to its only other consumer -- not as a speedup, and the
doc's "DONE" now describes something the archive actually contains.
Gate: tools/verify.py -- the checkin leg's 2 faults (2026-10-19-zephyrus.md,
2026-10-19-zephyrus-sovereignty.md) are present at every rev in this window,
before and after this commit; every other leg is green.
