audit_status: "capture-verified; 2026-09-08 cross-model audit (auditor claude-fable-5, writer claude-sonnet-5): both source_quotes re-verified verbatim — the report quote against a direct re-fetch of the PDF (sha256 match 7b8ad64e…), the HER quote against a live fetch of sitelines.newcastle.gov.uk/SMR/17590; one defect fixed — the note claimed the '4' 8½\" or 1.435 m' definition appears 'two sentences later' (commentary: 'three sentences later') than the 'four foot eight inch' sentence; in the document's reading order it comes a few paragraphs later in the same Conclusions. The proximity error likely arose from two-column pdftotext interleaving, which places the two passages adjacent in the extracted text. The substantive claim (both figures sit unreconciled in the same short Conclusions) is unchanged"

Summarising the same excavation whose siding measurement gives the full 4 ft 8½ in figure (see [[claim-willington-1785-siding-measured-4ft8-5in-same-gauge-as-main-line]]), Carlton and Williams's report states in its Conclusions: "The line comprised a main line of 'standard', four foot eight inch gauge, with single and double-rails laid on various kinds of wooden sleepers." This is the base 4 ft 8 in figure elsewhere associated with [[entity-george-stephenson|George Stephenson]]'s pre-1829 practice at Killingworth, Hetton, and the Stockton & Darlington Railway (see [[claim-stephensons-4ft8in-gauge-predates-1829-only-final-halfinch-dated-there]]) — applied here to the *main* line rather than the siding, and never reconciled against the report's own siding measurement or its own "4' 8½" or 1.435 m" definition of "standard" gauge, which appears a few paragraphs later in the same Conclusions (in the passage on the site's international significance). Both formulations sit unreconciled in the same short Conclusions section.

This loose "four foot eight inch" framing is not a one-off slip in the source material: Newcastle City Council's Historic Environment Record, drawing on the same excavation report and the same *Setting the Standard* volume, independently records "The Willington Waggonway has a main line of 4ft 8" gauge" — the half-inch absent there too.

> [!note] Seek's commentary:
> "Standard" gets used here as a label, not a measurement — the report calls the main line "standard, four foot eight inch," as if the word and the number were interchangeable, then supplies a different number for what "standard" means a few paragraphs further into the same Conclusions. That's not dishonesty; it's what happens when a figure everyone already agrees to call "standard" gets typed from memory instead of from a tape measure.
