Excerpt fidelity and placement audit (Q20) — 91 magazine entries, every-10th sample

Screen. Every row carries the entry URL and byte count, the cited article URL and byte count, the detag/normalisation rule printed below, and the offset arithmetic (offset in characters from the top of the detagged article body, plus its fraction of body length). Readings are from this host, 2026-10-11T13:09–13:10Z. Where a fact could not be verified it says unverified; there are none.

Sample rule (stated in advance)

• Population: the 91 magazine entries on https://alexanderwhitestone.com/stackchain/blocks/ (HTTP 200 / 34,488 B / 2026-10-11T13:09:26Z).
• Sample: every 10th entry in index order — magazine-002, magazine-012, magazine-022, magazine-032, magazine-042, magazine-052, magazine-062, magazine-072, magazine-082 (9 entries).
• Excerpt unit: every <blockquote> on the entry page with detagged text ≥25 chars, quote text taken as everything before the blockquote's own <cite>. 26 excerpts total (3+3+3+3+3+3+3+3+2).
• Pairing rule: the anchor inside the same blockquote (Q21's rule — the panel's own pairing wins); fallback to nearest anchor in the same DOM section, then to the entry's cited-sources list in order. All 26 rows used the panel's own pairing; no fallback was needed.

Detag/normalisation rule (printed so the numbers are re-runnable)

• Strip <script> <style> <svg> <noscript> <header> <footer> <nav> <form> <iframe> elements with contents; map <br> and block closers (</p> </div> </li> </ul> </ol> </h1-6> </tr> </td> </th> `) to a space; inline tags to nothing.
• HTML-unescape repeatedly until stable; NFKC-normalise; curly quotes to straight; em/en dash to -; ellipsis to ...; rejoin ordinal suffixes split by markup (4<sup>th</sup> → 4th); collapse whitespace. Applied identically to entry excerpts and article bodies.
• Classes, tested in order: (1) literal — normalised excerpt is an exact substring of the normalised body; (2) normalised-literal — equal after quote-style/dash/whitespace normalisation (names what was normalised); (3) elided — literal once the excerpt's own marked elisions ... are honoured (all segments resolve in order; offset = first segment); (4) paraphrase — not a substring under any stated normalisation, differing tokens quoted; (5) unreadable — target is an image, recording or X post whose fetched body does not carry the text (reason stated, no grade). For literal/normalised-literal/elided: start offset = first match, characters from the top of the detagged body; fraction = offset / body length. Paraphrase: best-match window offset, noted.

Named findings

• Paraphrase: none. 0 of 26 excerpts.
• Unreadable: none. 0 of 26 excerpts. All 9 cited article URLs answered HTTP 200 and each excerpt is an exact substring of the fetched target page.
• Placement caveat (magazine-082): the cited page carries almost no prose — the guest piece is an embedded interactive web app, and the two excerpts match the page title (offset 0) and the magazine's author-note (offset 291 of 788 chars) rather than guest prose. Both still grade literal by the stated rule; the evidence column says where each match sits.
• Distribution: placement fractions span the whole body (min 0.0000, max 0.9381) — excerpts are drawn from ledes, middles and closes, not from one fixed position.
