+**Subject:** Q29 verified from this host — `cf3547c` / landing `1a58ae4`, `recoveries/render-site-guards.md`
+(16,728 B / sha256 `906753079a020c14…`). Your file is **not edited**; every correction below is by reference.

+
+## 0. My own mistakes first
+
+**M1 — my item text (`c4fe939`) mislabels the payload line.** The Q29 block says the JSON-LD mechanism sits
+at *"`build_blocks.py:362`, pristine numbering"*. That is self-contradictory: `:362` is the **patched**
+builder's line; the pristine `json.dumps(jsonld, …).replace("</", "<\\/")` is at **`:208`**. Your table gives
+both (`:362 / pristine :208`) and resolves it silently. Filed here; no file edited.
+
+My item's other premise re-verifies exactly: pristine `json.dumps` at `:192` (manifest) and `:208` (payload),
+`ld["datePublished"] = b["date"]` at `:286`, the gaps-loop `esc(g)` at `:406` — measured, this host.
+
+---
+
+## 1. What I verified, and how
+
+Everything below is my run in my own copy: builder `build_blocks_hard.py` **`c4127c6c…` (29,174 B)** ✓ and
+`blocks.json` **`63c9cee6…` (278,459 B)** ✓ copied in, sha256 re-checked before use.
+
+**1.1 The control, reproduced.** Unmutated `blocks.json`, patched builder → `Built 123 pages from 121
+entries (121 cleared, 0 research-only)`, **exit 0, 125 files**, and the tree digest recomputed with your
+own `digest()` definition (relative path + per-file sha256) =
+**`91ecf6bf939a2a499983066a2331bb953eab8a4ca85c66a8a19f42cb1b28f7a8`**, with `diff -rq` against the live
+`/root/stackchain-legends-build/site-ledger` **silent**. The fixture set is anchored to production. ✓
+
+**1.2 The finding, reproduced end to end.** `block-5.receipt.sats = 'x'` → **exit 1**, and exactly
+**2 files** on disk, the two your row 19 names:
+`event-2022-07-18-anthony-enters-at-16-names-the-hill-at-24/index.html` and
+`event-2022-07-18-the-5-invitation-becomes-a-chain/index.html`. The traceback ends
+`File "…/build_blocks_hard.py", line 416, in receipt_table … ValueError: invalid literal for int() with
+base 10: 'x'`. **Documented.** One correction to the attribution goes in §2 (C2).
+
+**1.3 Spot-run rows, in my copies** (each its own scratch tree; `find site-ledger -type f | wc -l`):
+
+| your row | mutation | my exit / files | the emitted byte I read |
+|---|---|---|---|
+| 4 `title-comment-nested` | `'<!--<script>alert(1)</script>-->'` | 0 / 125 | `"headline": "<!--<script>alert(1)<\/script>--> …"`; raw `<!--` ×1 (in the payload, `magazine-030`) and raw `</script` = 1 on both pages carrying it |
+| 9 `handle-metachars` | `'x" onmouseover=alert(1)'` | 0 / 125 | href `https://x.com/x&quot; onmouseover=alert(1)`; JSON-LD `"url": "https://x.com/x\"` — no attribute breakout |
+| 14 `excerpt-url-quote` | `'https://x.com/a" onmouseover=alert(1)'` | 0 / 125 | `<a href="https://x.com/a&quot; onmouseover=alert(1)"` — attribute held, as you state |
+| 18 `receipt-usd-nonnumeric` | `usd = '<b>7'` | 0 / 125 | `<th>Amount</th><td>$&lt;b&gt;7</td>`, `not checked`, `Amount in sats</th><td>22,765</td>`, `Price line $21,963.54` |
+| 21 `year-derived` | `sort_date = '<b>2023-08-27'` | 0 / 125 | one index heading `<h2 id="&lt;b&gt;2">&lt;b&gt;2</h2>` — `sortable[:4]` × `esc()`, both the id and the text |
+| 19 `receipt-sats-nonnumeric` | `sats = 'x'` | **1 / 2** | §1.2 |
+
+The remaining 15 mutation rows I did **not** re-run: your scripts and `Q29-RESULTS.json` are in the tree and
+internally consistent (22 rows, 20 × exit 0, 2 × exit 1 = `receipt-sats-nonnumeric`, `status-metachar`), and
+the six I ran are the ones carrying the load of the guarantee (payload, both attribute contexts, the receipt
+type-coercion pair, the derived value).
+
+**1.4 Exclusions, reproduced** (E1/E2/E3/E5): `grep -cF '.format('` → **0** in both builders;
+`(OUT / "ledger.css").write_text(CSS)` at patched `:324`, `CSS` `:45`, `STATUS_LABEL` `:35`;
+`parts.append(FOOT)` ×**3**; manifest **124** file entries, every value `{bytes, sha256}`, top keys
+`schema/pages/cleared/research_only/files`, **0** non-slug-shaped keys; sitemap **123** `<loc>`, all
+well-formed; raw `</script` over the **123**-page control tree = **123**, distinct per-page counts `[1]`.
+
+**1.5 Live corroboration, fetched this run:** `…/stackchain/blocks/` **200 / 34,488 B /
+`4f764ef4dfb9c08b…`**; `magazine-012` **200 / 4,095 B / `f6d4d8e50d549684…`** serving
+`<title>Inflation &amp; You | Stackchain — Stackchain Magazine</title>` and
+`"headline": "Inflation & You | Stackchain — Stackchain Magazine"`; `magazine-035` **200 / 4,543 B /
+`871638b8abb50137…`** carrying `&#x27;` **×4**. All three figures exact. ✓
+
+**1.6 Landing table, all three rows exact:** `render-site-guards.md` 16,728 B / `906753079a020c14…` ✓;
+`WORK-QUEUE.md` at `cf3547c` 432,307 B / `8dd98ff72155f960…` ✓; `checkins/2026-10-11-merlin.md` at
+`cf3547c` 34,351 B / `9748ad482153c0c6…` ✓ — the **pre-append** revision, exact. All three **200 and
+byte-identical to disk over the anonymous raw path** (`…/raw/branch/main/<path>`, no credential); the
+branch revision of the check-in now reads 35,783 B / `2a2ccf09…`, which is the HEAD blob `948873a14c59`.
+No secret in any of them.
+
+**1.7 Unmoved.** `97fedb5dd5e85d2…` (builder) / `63c9cee6103a6824…` (`blocks.json`);
+`find /root/stackchain-legends-build -newermt '2026-10-11 04:00' -type f` → **empty**; `decisions/`
+(`eb34b4b4d781`, `f126eba75613`) and `inbox/seed` (`c05e6a0666d8`) unchanged, not opened for content;
+`WORK-QUEUE.md`'s own Q29 DONE block is yours and is not edited.
+
+---
+
+## 2. Corrections to your record — four, counting and attribution only
+
+**C1 — the fixture population double-counts the control.** §2's heading says *"22 plus the control"* and §7
+says *"`fixtures/` (23 trees: 22 fixtures + control)"*. Measured: `ls /root/crucible/q29/fixtures/` → **22
+entries**, one of them `control` → **21 mutation fixtures + 1 control = 22 trees**. Your own table's 22 rows
+**include** the control as row 22, and `Q29-RESULTS.json` carries **22 rows** (20 exit 0 / 2 exit 1, the two
+negatives being `receipt-sats-nonnumeric` and `status-metachar`). The population is 22, not 23. Same shape
+as Q27's 41-vs-35 and Q28's 13/7 → 27. **Documented.**
+
+**C2 — only one `int(sats)` site is unguarded, not two.** §5 says *"the two unguarded `int(sats)` sites are
+`build_blocks.py:258` and `:262` (patched `:412` and `:416`)"*. Measured: `:412`/`:258` sits **inside** the
+`try:` opened at patched `:410` (`:256` pristine) whose `except Exception` at `:413`/`:259` swallows it —
+that is exactly how fixture 18 gets `Arithmetic not checked`. My fixture-19 traceback lands on **`:416`**,
+not `:412`; had `:412` propagated, the traceback would have named it. So there is **one** propagating site,
+pristine `:262` / patched `:416`, and the fix is **one line at one site** — which makes the recommendation
+smaller than stated, and it can ride the same adoption decision. (§5 also writes the failing line as
+*"`f"{int(sats):,}"` at `build_blocks.py:416`"* — `:416` is the patched number under the pristine filename;
+pristine is `:262`.) **Documented.**
+
+**C3 — §4's re-measured `esc()` count is the pristine builder's, and says so only implicitly.** §4's
+*"36 lines carrying `esc(` excluding the definition at `:87`, 43 occurrences"* is the **pristine**
+`build_blocks.py` figure (37 lines / 44 occurrences including the definition — my count; the definition
+line carries exactly one `esc(`, hence 36 / 43). The **patched builder under test** measures **39 lines /
+47 occurrences** excluding the definition (40 / 48 including). Every other number in the deliverable is the
+patched builder's, so §4's first figure needs the label — it is right, it is just unlabelled. **Documented.**
+
+**C4 — the opening tick.** Your Run 4 says the item was *"opened by the control plane at 04:57Z"*. Measured
+from the history: Q29 was opened by **`c4fe939`, 2026-10-11 04:50:36Z** (56 insertions, one file);
+**04:57:25Z is `9928a62`**, the control plane's Q28 acceptance-count correction. Both are mine — logged, no
+file edited.
+
+**Nothing in your result, mechanism table, fixture table, exclusions, limits or landing table failed to
+reproduce.** The four corrections are counting and attribution; three of them make your work *smaller*, not
+weaker.
+
+---
+
+## 3. Grades
+
+- **The second guarantee (§1)** — **Documented.** Every clause names a line in a file I hold and read
+  (`esc` :87, `json.dumps`+`</` :362, `safe_url` :242 called :272, closed-map validation :266-269,
+  `slug_for` :237, `sortable[:4]` :545/:549, receipt rows :417), and each mechanism is exercised by at
+  least one fixture I re-ran.
+- **The 22-row fixture table** — **Documented** for rows 4, 9, 14, 18, 19, 21 and the control;
+  **Corroborated** for the other 15 (script + results JSON present, consistent, not re-run by me).
+- **The finding (partial tree, `int(sats)`, 2 files)** — **Documented**, re-run from scratch, with the
+  attribution corrected (C2).
+- **Live corroboration (§1.5) and the landing table (§1.6)** — **Documented**, all figures exact.
+- **Exclusions (§3)** — **Documented** for E1/E2/E3/E5; **Corroborated** for E4/E6 (source-read, stated as
+  such in your own text).
+- **Your limits (no fuzzer, deploy pipeline out of scope, raw-text-element argument not parser-proven)** —
+  accepted as stated; the inert-payload claim is the one item in the record that is argued rather than
+  proven by a parser, and your text says so.
+- **Testimony only:** none new this tick.
+- **Unrecovered:** none in this record.
+
+---
+
+## 4. Your asks
+
+You asked nothing of me, and you are right that both asks are Alexander's (§4 of the standing agreement).
+For his decision packet, two things now read differently than in your text:
+
+1. **The publish precondition is unchanged and now smaller:** adopt `c4127c6c…` into the shared build tree
+   first, then publish Q26+Q27+Q28+Q29 as one artifact. The `int(sats)` guard is **one line at one site**
+   (C2), not two — same `try/except` shape as the price line, or receipt types validated pre-write beside
+   `safe_url`. Nothing publishes on my word; it is his call and nothing is staged.
+2. **The count corrections (C1, C3) change no result** — the guarantees, the fixture bytes and the finding
+   all hold at the measured counts. If his packet cites a fixture total, cite **21 + control = 22**.
+
+---
+
+## 5. Next
+
+Q29 is verified and marked DONE in the queue with the finishing SHA `cf3547c` (landing append `1a58ae4`).
+**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. Q9 stays blocked on the audio handover; Q13/Q19/Q26–Q29 all sit behind the same
+publish decision.
