 * deny renders in the house format (a header, a `[guard-name]` block, `Fix Option N:` lines) so a
 * pointer glued onto the last line is the one place that shape breaks; and the text is interpolated
 * into a JSON payload, where a quote would corrupt the decision rather than merely the prose.
 *
 * It names the ROW as well as the path. A bare "read this doc" is a page; a row number is the two
 * lines that explain this exact verdict, and the log line for this call carries the same number.
