queue: Q29 DONE verified from this host, finishing SHA cf3547c recorded; four corrections appended

C1 the fixture population is 21 mutation fixtures + 1 control = 22 trees, not 22 + control (the control is
double-counted; the table's row 22 is the control and Q29-RESULTS.json carries 22 rows). C2 only one int(sats)
site is unguarded, pristine :262 / patched :416 - :258/:412 sits inside the swallowed try and the fixture-19
traceback names :416, so the fix is one line, not two. C3 the 36/43 esc() count is the pristine builder's (the
patched builder under test measures 39/47). C4 Q29 was opened by c4fe939 at 04:50:36Z, not 04:57Z. My own M1
filed first: the Q29 item text's ':362, pristine numbering' is self-contradictory. Control reproduced at
91ecf6bf / 125 files and byte-identical to the live site-ledger; fixture 19 reproduced exactly (exit 1, 2
files); rows 4/9/14/18/21 and E1/E2/E3/E5 clean; shared tree 97fedb5d / 63c9cee6 and live index 200 / 34,488 B
/ 4f764ef4 unmoved; his deliverable and DONE block untouched. No new item: Q20 and Q21 open and unclaimed.

@@ -3589,3 +3589,56 @@ numbers below are re-derived from that file plus `Q28-RESULTS.json`.
 - **Limits:** no fuzzer (the enumerated shape set only); the guarantee covers the builder's emit surface, not the deploy pipeline; fixture 19's partial tree is measured, its cause is source-read; the payload's raw `<`/`&`/`<!--` are measured-inert, argued from the raw-text-element rule, not parser-proven; no X page fetched this run.
 - **Testimony only:** none — every figure came from a command in this run.
 - **Q7, measured:** Q20 open and formally unclaimed (zephyrus-sparkborn's named lane); Q9 blocked on the audio handover; Q13/Q19 gated on Alexander; Q26/Q27/Q28/Q29 all gated on the same publish decision. No new item opened this tick.

+  unchanged and not opened for content; **his deliverable and his DONE block are not edited** — sole author
+  rule held.
+- **Corrections appended (prose only — four):** **C1** the fixture population is **21 mutation fixtures +
+  1 control = 22 trees**, not 22 + control / 23: `ls fixtures/` → 22 entries including `control`; the table's
+  own row 22 *is* the control; `Q29-RESULTS.json` carries **22 rows** (20 × exit 0, 2 × exit 1 =
+  `receipt-sats-nonnumeric`, `status-metachar`). **C2** only **one** `int(sats)` site is unguarded — pristine
+  `:262` / patched `:416`; pristine `:258` / patched `:412` sits **inside** the `try` whose `except Exception`
+  swallows it (that is how fixture 18 reads `Arithmetic not checked`), and the fixture-19 traceback names
+  `:416`, not `:412` — so the fix is **one line at one site**, not two. §5's `build_blocks.py:416` is the
+  patched number under the pristine filename (pristine `:262`). **C3** §4's re-measured `esc()` count (36
+  lines / 43 occurrences) is the **pristine** builder's (37 / 44 including the definition); the **patched
+  builder under test** measures **39 lines / 47 occurrences** (40 / 48 including) — right, but unlabelled.
+  **C4** the opening tick: Q29 was opened by **`c4fe939` at 2026-10-11 04:50:36Z**, not 04:57Z (04:57:25Z is
+  `9928a62`, the Q28 acceptance-count correction). **My own mistake, filed first:** the Q29 item text's
+  *"`build_blocks.py:362`, pristine numbering"* is self-contradictory — `:362` is the patched line, pristine
+  is `:208`; his table gives both and resolves it. **Nothing in the result, mechanism table, fixture table,
+  exclusions, limits or landing table failed to reproduce; three of the four corrections make the work
+  smaller, not weaker.**
+- **No new item opened this tick** — the queue is not thin: Q20 (:2150, zephyrus-sparkborn's named lane) and
+  Q21 both sit open and formally unclaimed, and this tick's residue is a one-line source fix gated on
+  Alexander, not an item. The publish precondition stands as the one decision in front of it: **adopt
+  `c4127c6c` into the shared build tree first, then publish Q26+Q27+Q28+Q29 as one artifact** — Alexander's
+  call; if the packet cites a fixture total, cite **21 + control = 22**.
