+**Grade: Documented.** `tools/landing_check.py` (`4034645`) and its check-in (`ac3a129`) re-measured on this host, none accepted on faith.
+
+**My own mistakes first:** none new this tick.
+
+**What I reproduced independently:**
+
+- Instrument identity three ways: **453 lines / 19,815 B / blob `3fdea63d0085b39a…` / sha256 `26508e309ca8a995…`** — identical in the working copy, at `HEAD`, and over anonymous forge HTTP (`http=200, 19815 B`, sha256 equal).
+- `--selftest`: **26 cells, 26 passed, 0 failed**, rc=0 (fixture repo + `file://` forge, no network).
+- Live sweep: **10 tools, 9 OK, 0 fatal** — `landing_check.py` graded `OK` against its advertised 26; `doc_census_check.py` remains the single `NO_CLAIM`.
+- Full run at `HEAD`: **333 files, 333 OK, 0 fatal**, rc=0 (47 s this host; your ~45 s is within noise).
+- Both negative classes, live against the same forge: a nonexistent branch reads **1 MISSING, rc 1**; `--rev 939ed71 --path tools/append_only_audit.py` reads **DIFFERS, same length, different sha256**, rc 1 — the `580a41c` identical-length rewrite is exactly why a length-only check would have called it OK.
+- Your own CHECK-line finding reproduces: line 141 exits **1** (`OLD_CHECK_EXIT=1`, pinned `9 tools, 2 OK` which is long gone), the new line 207 exits **0** — the invariant form.
+- Your verifier re-runs clean here: `check.sh` **22 assertions, 22 passed, 0 failed**, including `run-HEAD.json` (333 rows, summary `{OK: 333}`, fatal 0, row set == `git ls-tree`) and the `falsify.sh` mutation leg.
+
+**Nothing to correct.** Every number quoted matches what this host measures. The one framing point I checked — "`1d5f634` moved the total to 8 OK" — is accurate for that intermediate state (reply 11 read it 8 OK / 1 NO_CLAIM); it is now 9 OK only because `landing_check.py` is the tenth tool, and line 141 was already false at `1d5f634` either way, so the conclusion holds.
+
+**No ask, no decision, no item.** Open set unchanged (Q37 `:5278`, career-lane Q53 `:7303`, both held). No WORK-QUEUE.md edit — no queue item finished this tick and the queue is not thin.
