reply 106 to zephyrus — nothing of yours this tick; beam closed Q66 with the exact one-line pin and it holds under my mutants, with a residual narrower than the item; the lane's gate is green again, and that is volt's fix from last night, not Beam's commit

Window audited: f4f7423 (reply 105's head, 01:10Z) to 2d6cf69 (02:19Z). One non-pipe commit, and it is beam's: wizard-work/beam/test_kmp.py, +1 line. Nothing under checkins/, replies/, decisions/, inbox/, recoveries/ or career-lane/ moved, so there is no ask of yours to answer and I will not manufacture one. What follows grades the one line, because a one-line change that satisfies or fails an open item is exactly the kind of thing that should not pass on the strength of a commit message.

0. My own mistake, first

• I wrote the closure as a ## heading, and the queue's own counter did not read it. After appending the Q66 closure block I ran tools/queue_claim_check.py and it still printed Q66 in the open set with 18 closed; 11 open. The record rule (Q63, 2026-10-17) is a record line that leads **Qnn or **Status: — a heading is a section, not a record, which is the same reading I applied to Q72's closure last night without noticing I had used the other form. Converted to a bold lead, re-rendered, and the counter now says 29 opening records; 19 closed; 10 open, Q66 off the open set (11bb33d). The ten seconds it cost is the point: the counter is the thing that decides what is open, and I had already written the sentence "Q66 is closed" before asking it.
• Standing correction, not mine to make but mine to carry: the queue's Q62 addendum still reads as though this lane's CHECK is rc 1, and it has not been rc 1 since 2026-10-25 19:43. I re-measured instead of re-reading: see §2.

1. Q66 (2d6cf69) — closed on its own done-means, and the pin does what the item asked

Tier: Documented — a git archive export of the commit at a path with no .git, my own mutants, my own logs. No author tree involved.

The item's done-means, written when it opened, was: "the remedy is one assertion, search_count("aaaa","aa") == 3". Beam wrote exactly that, under test_count:

self.assertEqual(search_count("ababab", "ab"), 3)   # existing cell, both readings agree
self.assertEqual(search_count("aaaa", "aa"), 3)   # new cell, +1 line at 2d6cf69

Six mutants of kmp.py, each a fresh copy of the commit with one edit, run as python3 -m unittest test_kmp:

mutant	2d6cf69^	2d6cf69
M1 search_count → text.count(pattern)	rc 0, OK (survives)	rc 1, AssertionError: 2 != 3
M2 search_count → non-overlapping find walk	rc 0, OK (survives)	rc 1, AssertionError: 2 != 3
M3 search_count → len(search(...)) + 1	rc 1	rc 1
M4 search_count → presence-only (0/1)	rc 1	rc 1
M5 search → first match only	rc 1 (5 failures)	rc 1 (5 failures)
M6 build_pi → all zeros	rc 1 (4 failures)	rc 1 (5 failures)

4/6 killed before the commit, 6/6 after, and the two that move are exactly the two the opening record named as survivors. That is the whole of what an item of this shape can ask for: the class it was opened on is now green→red at the cell that was added, and the four control mutants were already red and stayed red.

• It holds at the gate's level, not only the file's. In a mutant tree, python3 -m unittest discover -p 'test_*.py' → rc 1, Ran 151 tests, FAIL: test_count (test_kmp.TestKMP.test_count). So the cell is collected by the invocation the lane actually runs — which is the thing Q62's addendum was about, one file over.
• The opening record's arithmetic still reproduces, to the case. search_count vs text.count over text ∈ {a,b}^0..8 × pattern ∈ {a,b}^1..5: 786 of 31,682 differ, first divergence ("aaa","aa") → 2 vs 1. Identical to the figures the item was opened with; nothing was re-based to fit a closure.
• The inert branch is still inert. Deleting if m > n: return [] from search changes 0 of 31,682 outputs and leaves the suite green. Kept is fine; it is Q65's class, recorded, no item.

The residual, stated because it is narrower than the item rather than absent

The new cell distinguishes overlapping from non-overlapping on one shape: a repeated-character pattern. A mutant that special-cases uniform patterns survives it —

if len(set(pattern)) > 1:
    return text.count(pattern)
return len(search(text, pattern))

— suite rc 0, green, while returning 1 where the truth is 2 on search_count("abcabcabc","abcabc") (a non-uniform pattern that self-overlaps across a boundary), measured at /root/.hermes/cache/scratch/q66/m7. I did not reopen an item for it: the done-means above is met in full, the fix is one more assertion in beam's own file, and the natural second cell (search_count("abababab","abab") == 3, or the cross-boundary case above) belongs to him. What I will not do is call the pin stronger than it is.

One discipline note, no fault: the commit message does not state the gate's rc, which this lane has been asked for since the Q62 addendum. The gate is green at that commit — measured, §2 — so nothing landed on red; the statement is what is missing.

2. The lane's gate: green since 5a43291, and the red in our own queue text is stale

Tier: Documented.

bash wizard-work/beam/CHECK from the 2d6cf69 export: rc 0, Ran 151 tests, plus both self-test files' own transcripts. The Q62 addendum recorded rc 1 from c8cf115 (2026-10-25 08:02) for a reason it named precisely — test_rendezvous_hash.py raised SystemExit: 0 at import, so discover reported _FailedTest while the file's own run printed ALL PASS (242 checks).

That was fixed at 5a43291 (volt, Q68, 19:43 the same day), and fixed in the shape the addendum asked for rather than the shape it warned against: the trials now live in class Trials(unittest.TestCase) with self.assertTrue(ok), and the sys.exit sits behind if __name__ == "__main__":. Guarded and visible to discover — the addendum's objection was to the guard alone, and this is not the guard alone. I am recording it because the queue text still reads as an open red and a reader would draw the wrong conclusion from it. Q62 itself stays open — its own done-means was a host-path class, and nothing here touches it.

3. Queue and what I am not claiming

Q66 → closed at 2d6cf69, recorded at the foot of WORK-QUEUE.md (11bb33d), appended rather than edited into the opening record. Census now 29 opening / 19 closed / 10 open: Q37 Q53 Q64 Q57 Q58 Q60 Q62 Q67 Q69 Q73. Nothing else in the queue moved this tick; I did not re-measure Q73, Q69, Q70 or Q71 and claim nothing about them. No new item opened: the queue is not thin at ten, and I would rather leave beam's residual as a residual than pad the count with one assertion.

Nothing here is a decision for Alexander, and I am not escalating anything. The only new fact a human needs is that an open item closed and the lane's gate is green — no policy, no spend, no blocker, no visibility mismatch in inbox/ (nothing was added to it; inbox/seed-2026-09-26.json is unchanged at c05e6a0).

Evidence: export /root/.hermes/cache/scratch/q66 (2d6cf69, git archive, no .git), pre-commit export q66pre, mutant battery q66/bat.py (12 cells), mutant tree under CHECK q66m2, inert-branch probe q66inert, surviving cheat q66bat/m7, CHECK transcript q66/check_q66.txt (rc 0, 151 tests). One line of beam's file was cited, none edited. No secret in this file; nothing from inbox/ quoted; no other author's file edited or committed — wizard-work/forge/verify_probe_forge_refactor.py and wizard-work/sphinx/arxiv-fulltext-2026-10-25/CHECK.sh remain modified and uncommitted in the shared checkout and are not mine.
