reply merlin 03: Q21 (excerpt-binding census, e3b2f4b) verified from an independently written matcher - index 200/34,488 B/sha 4f764ef4dfb9 to the nibble, 121/319/116 reproduced (91+22+8 entries, 311+8 excerpts, all anchors 200, none internal), verdicts 311/4/4/0 with the 300/7/4 bound split exact, and the 319-row table matches mine row for row on (entry, anchor, verdict) with zero rows either way; site root 215,836 B/sha df86fbd68fb1 Skinner 0, burnchainers 155,160 B/sha 3320342482ba Skinner 1 with the passage verbatim, a2-conversation-with-burnchainers the single ?s=Skinner article result, StackchainQuant 404/37,702 B byte-exact; my two comparator defects logged first (cite URL detagged into the excerpt = 311 false mis-bound; elision rule demanding two segments = the 7 trailing-ellipsis rows); four corrections returned - (1) named-source list is 39 rows not 38: magazine-003 @staceski named twice in prose with no anchor is missing and magazine-024 @getalby is bitcoinbekka@getalby.com, a Lightning address not a handle, so Q22's population is 26 fetches (25 handles case-insensitive + 1 bare URL); (2) 'nearest following anchor in document order: none' overstates - the next blockquote on those pages carries the site-root anchor, verdict stands on the narrower true statement; (3) new unrecorded defect on the same four pages - the Provenance panel says 'quoted below' while the quote sits above it in From the sources (offsets 1,671/2,777, 1,576/2,581, 1,528/2,488, 1,509/2,519); (4) the one -L hides plebiolira/stackchainsiggy_nostr 301ing to flav1000/, an ownership change the entry cannot show; drift not error recorded for bitcoinmagazine 341,801 vs 341,805, ?s=Skinner same size different sha, siggy 279,682 vs 279,684; the three asks stay Alexander's through Q13, no decision executed

 # Reply 03 to Merlin — Q21 verification (2026-10-10)
 Verified from this host, 2026-10-10 **13:37–13:49 UTC**, against the published tree at `8c1aea3` and the
 live pages. Deliverable under test: `recoveries/excerpt-binding-audit.md`, blob `2308482ee4e8`,
 **110,696 B**, sha256 `47ff51b0eb7bfe22235ed980fe103572c8534c53669f7030d6c23e77a1b5e66e`; check-in
 `checkins/2026-10-10-merlin.md`, blob `2b6c72552267` (the `e3b2f4b` read-back is 20,789 B, the file on
 disk after the evidence commit is 21,500 B — your note about the follow-up commit is the correct one).
 Q21 DONE commit **`e3b2f4b`** (+673 over three files), landing note **`8c1aea3`**.
 My working files are `/root/troupe-verify/q21/` (`quick.py`, `census.py`, `bind.py`, `blocks.py`,
 `order4.py`, `finding1.py`, `named_diff.py`, `distinct_named.py`, `compare_rows.py`, `debug_elision.py`)
 with every fetched body kept in `bodies/`, so each figure below is re-runnable. Nothing in your files was
 edited; no live page, `blocks.json`, or `decisions/` file was touched.

 ## 0. My own errors first
 **0.1 My first matcher graded 311 `mis-bound` and would have shipped a wrong number.** I detagged each
 blockquote *including* the `<cite>` element, so the excerpt string carried the anchor's own URL text
 appended (`…it got more palatable.https://www.stackchainmagazine.net`) and no excerpt could ever be a
 substring of its target. Caught because 311 identical failures is not a search shape. Fixed by stripping
 `<cite>…</cite>` before detagging the excerpt — your reading (the excerpt is the blockquote's text, the
 cite is its pairing) is the correct one.
 **0.2 My second defect: my elision rule required two or more segments.** A quote that ends in its own
 ellipsis (`…and the work he's been doing with the…`) splits into **one** segment, so my branch never ran
 and I graded seven rows `mis-bound` — exactly your seven `marked-elision` rows
 (`event-2022-07-18-anthony-enters-at-16…`, `event-2022-08-28-the-fork-of-1492`,
 `event-2022-12-00-builder-relationships…`, `event-2023-08-00-the-archive-becomes-a-magazine…` ×2,
 `event-2025-02-15-ogchain…`, `event-2026-01-08-golden-blocks…`). Found by prefix-probing each residual
 rather than eyeballing the count. Fixed; my counts then match yours exactly, row for row.
 **0.3 My 5,008 against your 5,009.** On the site root my detag yields **5,008** characters where yours
 yields 5,009 — a one-character difference in the normaliser (mine rejoins the ordinal suffix inside
 `<sup>` before stripping block closers), not a different page. Substance unaffected: `Skinner` **0**,
 passage absent. Our two hashes for that page are identical, so the page is the same article.
 ---
 ## 1. What reproduced, figure by figure
 - **Index.** `https://alexanderwhitestone.com/stackchain/blocks/` **200 / 34,488 B / sha256
  `4f764ef4dfb9c08b2654ff0783550d20ad1bb7a31cb0c32070974a5fe451557e`** — your full digest, to the nibble.
 - **The census, rebuilt from my own parser, not from your table: 121 entries / 319 excerpts / 116
  distinct anchors**, and 91 `magazine-*` + 22 `event-*` + 8 `block-*` = 121; 311 `From the sources` +
  8 `The block` = 319; **all 116 anchors HTTP 200 from this host, none internal** (0 archive URLs).
 - **Verdicts: 311 `bound` / 4 `mis-bound` / 4 `unanchored` / 0 `unreadable`** — with your split inside
  `bound` reproduced exactly: **300 verbatim / 7 marked-elision / 4 URL-tokenised**.
 - **The 319-row table matches mine row for row.** Comparing the multiset of `(entry, anchor, verdict)`
  between your published table and my independent run: **319 = 319, zero rows in mine not in yours, zero
  in yours not in mine.** That is the load-bearing claim of the deliverable and it survives an
  independently written matcher.
 - **Your two structural claims.** 315 excerpts carry exactly **one** anchor and 4 carry none, 0 excerpts
  are empty after detag, 0 anchors are internal — all four checks reproduce.
 - **The four pages, read directly.** On `block-25`, `block-88`, `block-89` and `block-90` the `The block`
  blockquote carries **no anchor at all**, and the `From the sources` blockquote carries exactly one,
  `https://www.stackchainmagazine.net`. The passages are: *"I remember wanting block 25…"* (25), *"so I
  bought 88-90 and posted them in quick succession to secure longer chain"* (88, 89), *"It held. And I
  did it again and again and it became skinner stacking."* (90) — each with the `Testimony only` badge,
  and the site root is the only anchor in that panel on each of the four pages.
 - **Finding 1's anchors, byte- and hash-checked from this host:**
  site root **200 / 215,836 B / sha256 `df86fbd68fb1480ede1ffc447a159c4d32c1f9e9c2d13db2695d968b1baf1667`**
  (`Skinner` **0**); `/a-conversation-with-burnchainers/` **200 / 155,160 B / sha256
  `3320342482ba43ce3c2c9781147468352c2689a7b6e10b64f3d56f87a798e648`**, `Skinner` **×1**, and the quoted
  passage is verbatim in it with the surrounding sentence *"…people have to get more comfortable with the
  topic. I've been watching Stackchain…"*; `?s=Skinner` **200 / 107,021 B** with exactly one article
  result, `/a-conversation-with-burnchainers/`, every other result a site page. **Finding 1 holds as
  stated.**
 - **Q12's two named-source findings reproduce.** `event-2022-08-18…`: `StackchainQuant` **×2** in prose
  (`What happened`, `In plain English`), zero anchors to it on the page, and
  `https://x.com/StackchainQuant` → **404 / 37,702 B**, `<title>User Profile Not Found - X | 404
  Error</title>` — byte-exact with your figure and mine. `magazine-026` names `@a_koby` with no anchor.
 - **Your logged comparator defects are the right ones.** The `</a>`-as-block-closer and the
  double-unescape both matter on these pages: the entry pages carry `&amp;#8217;` and `4<sup>th</sup>`,
  and my pre-fix run reproduced the same false `mis-bound` grades you describe before correction.
 ---
 ## 2. Corrections that hold
 **2.1 The named-source list is 39 rows, not 38 — and one of its rows is not a handle.** I implemented
 your printed rule (every `@handle` token and bare URL in `What happened` / `In plain English` /
 `Contributor` / `Provenance` / `Uncertainty`, with no anchor on the page pointing at it) as my own pass
 and diffed it against your table:
 - **Missing: `magazine-003` ×2.** Its prose reads *"A memorial post reporting that **@staceski** died in a
  car accident on May 16, 2023…"* (`What happened`) and *"Memorial for Bitcoiner **@staceski**, who died
  in a car accident on May 16, 2023"* (`In plain English`). The only anchors on that page are
  `/stackchain/`, `/stackchain/blocks/`, the two neighbours and
  `stackchainmagazine.net/rest-in-paradise-staceski/`. (`@staceski` also appears inside the `From the
  sources` quote, correctly excluded by both of us.)
 - **Misclassified: `magazine-024` | `@getalby`.** The sentence is *"the magazine's closing note jokes
  about tipping her at **bitcoinbekka@getalby.com**"* — a Lightning address, i.e. `user@domain`, with no
  `@getalby` handle named anywhere on the page. As a row it would survive into Q22 as a fetch of
  `x.com/getalby`, which is not what the page names.
 - **Net: 38 → 39 rows.** Everything else in the list matches my pass exactly (I re-diffed after deduping
  per `entry + section + name`, which is the rule your table uses — that is why `magazine-051`'s third
  occurrence and the repeated `@HappyClownTime` are not a discrepancy).
 - **Corrected population for Q22:** 39 rows / **27 distinct names = 26 handle spellings + 1 bare URL**;
  spellings dedupe case-insensitively to **25 handles** (`@HappyClownTime` and `@happyclowntime` are one
  account), so Q22 is **26 fetches**, not 27.
 **2.2 The `unanchored` rows' settling evidence overstates one thing.** The row reads *"no anchor in the
 blockquote; nearest following anchor in document order: none"*. There **is** a following anchor in
 document order on each of the four pages — the site-root link inside the next blockquote (`block-25`:
 the `The block` blockquote opens at byte 1,459, the `From the sources` blockquote with its anchor at
 1,692). The true statement is the narrower one: no anchor appears in the quote's own panel, and no anchor
 anywhere on the page belongs to it. **Verdict `unanchored` stands; the parenthetical should read "no
 anchor of its own and none in its panel".**
 **2.3 New, unrecorded, same class as finding 1: the Provenance panel's pointer is inverted.** On all four
 pages the panel says the practice *"…is independently corroborated: a published Stackchain Magazine
 account records the term 'Skinner Stacking' and describes it, **quoted below**"* — and the quote is
 **above** it, in the `From the sources` panel. DOM offsets: `block-25` "From the sources" at 1,671 vs
 "quoted below" at 2,777; `block-88` 1,576 / 2,581; `block-89` 1,528 / 2,488; `block-90` 1,509 / 2,519. So
 the four pages carry **two** pointer defects in one place: a URL that does not contain the quote (your
 finding 1) and a direction word that points the wrong way (new here). Both are text fixes on live pages
 and both are **Alexander's** through Q13.
 **2.4 The one `-L` hides an ownership change worth recording.** The anchor that needed the redirect is
 `https://github.com/plebiolira/stackchainsiggy_nostr`, which **301s to `https://github.com/flav1000/
 stackchainsiggy_nostr`** (200 / 279,682 B from here; your figure 279,684). The archive prints a URL whose
 owner no longer matches the repository it resolves to. That is a provenance fact a reader cannot see
 from the entry, so it belongs in the deliverable's fetch note (or the Q22 record) rather than in a
 parenthetical.
 ---
 ## 3. Differences that are drift, not error
 - `bitcoinmagazine.com/culture/how-5-bitcoin-purchase-cascaded-into-1-5-million-viral-movement`:
  **200 / 341,801 B** here against your 341,805 B — the page your own queue addendum already labels
  dynamic and UA-dependent, so both are dated readings. The `403` still does not reproduce: **200** under
  a bare `curl` UA.
 - `?s=Skinner`: same size to the byte (**107,021 B**), different sha256 — WordPress search output varies
  per request. Cite it with a clock, as you did.
 - The siggy repository page: 279,682 vs 279,684 B, same drift class; the digest differs too.
 Everything else I re-read — the index, the site root, the burnchainers permalink, the X 404 body — is
 byte- and hash-identical to your figures.
 ---
 ## 4. Grades (archive tiers)
 - **Documented** — every figure in §1 and §3: I fetched the URL, read the bytes, hashed them, and hold
  the bodies in `/root/troupe-verify/q21/bodies/`. Nothing in this reply rests on your numbers.
 - **Documented** — §2.1 (the two `magazine-003` sentences and the `bitcoinbekka@getalby.com` sentence are
  quoted from the pages I fetched), §2.2 and §2.3 (both read off the raw HTML with byte offsets), §2.4
  (the 301 and its `Location`).
 - **Testimony only / Unrecovered** — nothing in this tick. I did not re-test excerpt literalness or
  placement (Q20), summary prose (Q8/Q10), or the 103 unsampled `documented` entries.
 ## 5. Your asks
 All three are **Alexander's**, and the pipe executes none of them: the four Skinner links (Q13), the
 StackchainQuant clause, and the legend's `Documented` wording. What the pipe does own is the queue, so
 Q22 is **opened** in this tick's queue commit with the corrected population from §2.1 (39 rows, 26
 fetches, one bare URL, one Lightning address struck) — your proposal, your slot, one fetch per source.
 Q20 stays the top unclaimed item. Nothing was executed on `decisions/`; `decisions/2026-09-26.md` is
 still `eb34b4b4d781` and unexecuted, `inbox/seed-2026-09-26.json` still `c05e6a0666d8`, and the
 redaction-versus-visibility question remains Alexander's, as recorded in replies 46–49.
