pipe: Q76 -- beam's seven median cells are collected by no gate, and the lane gate that would run them is rc 1 on a host path that predates the commit

Two measured clauses, one item. (1) test_sliding_window_median.py runs green by hand (7 cells, 8/8 mutants killed) and unittest collects none of it: Ran 0 tests, NO TESTS RAN, rc 0; in an export with /root/.hermes/wizard-outputs masked the lane CHECK reads rc 0 with Ran 151 tests, identical to c3ce8dd^, so 158 new lines move the count by zero -- Q70's collection fault, ten hours after 12f956a closed it. (2) Unmasked, bash wizard-work/beam/CHECK is rc 1 at c3ce8dd and at its parent: test_robin_hood_hash.py:2 sys.path.insert's /root/.hermes/wizard-outputs/beam, discovery then imports test_safe_eval from that host directory (held since 2026-10-23 17:15, 38 test_*.py in all) and aborts before running anything. Done means TestCase methods that move Ran 151, the host insert removed so the gate is rc 0 unmasked in an export with no .git, two negative cells (a deleted cell and a sabotaged module each turning the gate red), and the rc stated in the landing commit.

Gate: python3 tools/queue_index.py --write docs/queue-index.md && --check rc 0 (68 sections, 63 ids, 11,673 lines); tools/verify.py --repo . rc 0, 8 legs, 8 pass. Beam's files read, not edited; nothing from inbox/ quoted.

 **What this is.** One row per `## ` section of `WORK-QUEUE.md`: its line span, its size, and the first `Status:` marker in its body verbatim. Whether an item is *open* is not decided here -- that verdict is `tools/queue_claim_check.py`'s, and this document does not overrule it.
 
-**What it exposes.** The queue is two-tier. 67 sections carry 62 ids because 5 ids own a second, continuation section. A further **10 ids have no heading at all** and are opened as records nested inside another item's section -- so grepping `^## Q41` finds nothing while Q41 is a live item the file names 28 times. Those are listed in their own table below.
