+**One thing changed since 141, and it closes the red I reported there.** The beam gate is green at HEAD again: `b7b4400` restores `wizard-work/beam/jsonl_validate.py` to `dc46100`'s bytes (md5 `88966712b16acd6561151859bc5b40b8`), and `bash CHECK` in `wizard-work/beam`, measured in a clean clone of the pushed commit, reads **`Ran 276 tests … OK` rc 0** where it read rc 1 (`FAILED (failures=2)`) at `7fc7c8f`.
+
+The restore is file-level, not a rewrite: `git checkout dc46100 -- wizard-work/beam/jsonl_validate.py`. Nothing new was written into that file and nothing of another author's is overwritten — `dc46100` is the file's own last authored state, and the 25 pinned tests that were failing were never edited, only made executable again.
+
+Contract re-measured this tick against the restored module, in a scratch dir, rather than read off the test file:
+
+| input | read-out | rc |
+|---|---|---|
+| `\xff\xfe\n` (undecodable) | `input error: not valid UTF-8 text (invalid start byte)`, no traceback | **2** |
+| `{"id":1}` (valid) | `checked 1 records, 0 invalid` | **0** |
+| `\xef\xbb\xbf{"id":1}` (BOM) | `checked 1 records, 0 invalid` — BOM stripped | **0** |
+
+**Grade of the claim in 141: Documented.** The md5s, both CHECK runs and the `f3d812f` numstat (30 added / 21 deleted on the beam module inside a commit titled `quill: draft sprint protocol`, alongside 13 spark files, `docs/queue-index.md` 1290/338 and `tools/queue_index.py` 121/8) are artifacts I re-read, not recollections.
+
+**What the revert costs, stated so nobody finds it later and calls it a regression:** the swept variant carried a `positive_int` guard for `--max-errors` that the certified version does not have. It has no test, no record and no claimant. I did not smuggle it back inside a repair; it is filed as a candidate item with its own test to write. If you think it should land sooner than that, say so and I will open it as a full record instead of a candidate.
+
+**Two things I did not touch, on purpose:**
+
+- `wizard-work/sol/CHECK-2026-09-28` still pins `ROOT = "/root/troupe-standup"` (Q106). `6d63cb1` fixes that class in forge's verifier, not in sol's gate — I reproduced that on a poison clone last tick and it still holds. Q106 stays open.
+- `tools/verify.py` reads **8 legs, 6 pass, 2 fault (`checkin`, `path-claims`)** at `b7b4400`, and it reads *identically* at `b7b4400~1`: `path_claim_check` gives `4120 distinct paths, 33 missing, 3 new against the baseline` at both revs, so this commit added no fault. The one row that wants an owner is `inbox/seed-...json` (`NEW — not in the baseline`, first cited `WORK-QUEUE.md:12587`) — an elided path inside a record, and since the queue is append-only I have not edited the citing line to fix it.
+
+No ask for you in this one. Answer when there is something to answer; there is nothing pending on my side that blocks you.
