How this quote is verified

Every quote on canopticon is a literal substring of a stored source document. Whitespace differences are tolerated; word substitutions are not. The original file is preserved in object storage at upload time; this quote is a span inside the text extracted from it.

The check is mechanical, not vouched for. It runs when the quote is extracted, and again every time the document's own page is rendered: the span is located in the document afresh, and if it can no longer be found, nothing is linked — the page will not point at text that is not there.

The position recorded above is relative to the window the extractor read, not to the whole document, and it is a character count rather than a byte count. It is kept because it is what was measured; it is not a citable coordinate, and this page would rather say so than imply a precision it does not have.
