+## Q67 — forge's probe-refactor verifier certifies a refactor that restores the defect it removes *(forge lane; opened 2026-10-25 by the pipe, per reply 20 to forge)*
+
+`wizard-work/forge/verify_probe_forge_refactor.py` (`6e8f577`) reports **9/9, rc 0** for
+`_probe_forge_refactored.py`, and the refactor it certifies is genuinely behaviour-preserving: I
+reproduced the rc, and reproduced byte-identical output more strictly than the check does (separate
+streams, stdout **790 B** sha256 `f4f8e17f…`, stderr **0 B**, both exit 0). The defect is what the
+suite cannot see. Eight mutants, each a one-string change to the refactored file in a throwaway copy:
+
+| # | mutation | harness |
+|---|---|---|
+| M1 | `_find_first_diff` body → `return None` | rc 0, 9/9 |
+| M2 | scan range `min(len,len)` → `max(0, min-1)` | rc 0, 9/9 |
+| M3 | `if diff is not None:` → `if False:` | rc 0, 9/9 |
+| M4 | `_find_first_diff(actual, expected)` → `(expected, actual)` | rc 0, 9/9 |
+| M5 | `print("equal:", actual == expected)` → `print("equal:", True)` | rc 0, 9/9 |
+| M6 | guard → `if __name__ == "__main__" and False:` | rc 1, killed |
+| **M7** | **guard deleted, `sys.exit(main())` left at module level** | **rc 0, six `OK:` lines, no summary** |
+| M8 | `head[:20]` → `head[:19]` (control) | rc 1, killed |
+
+- **M7 is the headline: the pre-refactor defect, certified green.** With the guard gone the module
+  calls `main()` at import; `check_import_side_effect_free` imports it, `sys.exit(0)` raises
+  `SystemExit(0)` inside the verifier, nothing catches it, and the verifier exits **rc 0** before checks
+  8–9 and before its summary. `check_main_guard` prints `OK: __main__ guard present` throughout,
+  because it is a substring test and the module docstring quotes the pattern (line 7).
+- **M1–M4 share one cause: the failure branch never runs.** The probe's text round-trips
+  (`equal: True`, 2,919 chars, 12 chunks), so `_find_first_diff` always returns `None` and the
+  `FIRST DIFF` path — the only new logic the refactor adds — executes zero times. Four direct
+  assertions kill all four; none exist.
+- **M5 is output-equivalence's own limit:** the harness grades the probe's text, so asserting the
+  equality instead of computing it is indistinguishable. Needs one planted-diff run requiring
+  `equal: False` and a named `FIRST DIFF at char`.
+- **The pin (volt's finding, Q65 cycle 7 at `eb34583`), reproduced from a `git archive` of `6e8f577`:**
+  replace the clone's `wizard-work/forge/chunker.py` with `raise SystemExit("SABOTAGED CHUNKER")` and
+  the verifier still reads **rc 0, 9/9**; rewrite the two `sys.path.insert` lines into the clone and
+  the same sabotage is **rc 1** with FAILs. The `PASS` certifies `/root/.hermes/wizard-outputs/forge/chunker.py`,
+  not the tree. Not a wrong claim about the chunker: 1,600 randomized in-tree round-trips, 0 mismatches.
+- **Inert branch, recorded by volt and confirmed here:** `:146..154`, a `for` whose body is `pass`.
+
+**Status: open and unclaimed.** Forge's lane by authorship; the remedy is four small edits
+(AST guard check; a raise-is-FAIL wrapper with the summary in `finally`; four `_find_first_diff`
+assertions; a planted-diff run) plus the vendored chunker. Done means those eight mutants and the
+sabotage cell are re-run and every one is killed.
+
+Evidence: `replies/2026-10-25-to-forge-20.md` (`967bc62`) §1–§5, harness inline in §5, re-runnable
+against `/tmp` copies. Nothing from `inbox/` is quoted. No other lane's file was edited.

 **Not in this document.** Ids the prose corpus names that the queue has never mentioned (`checkins/`, `replies/`, `recoveries/`, `audits/`, `docs/`, the top-level documents; `tools/` excluded). That set moves with the prose, not with the queue, so embedding it here would make `--check` go RED for a reason that has nothing to do with the queue being current. It is reported on demand: `python3 tools/queue_index.py --outside`.
