docs(F1): settle the Good Friday Gloria on the source's own evidence

F1 adjudicated the FIUV ordo's Good Friday "Gloria" against the ordo, but
rested on external attestation and left a pdftotext misread unruled-out.
The page image resolves both.

The extraction is faithful: the printed book does carry that line. So the
adjacent-block-misread possibility is ruled out rather than merely doubted.

And the same page shows the compiler knew the distinction. Holy Saturday,
its next entry, carries no Mass line at all -- correctly. Easter, the entry
after, carries a full one -- correctly. Good Friday, which likewise has no
Mass, wrongly receives one, word-for-word identical to Holy Thursday's on
the preceding page, while its own Vespers rubric four lines below calls the
day's rite an Actio liturgica rather than a Mass.

Verdict unchanged. It now rests on internal evidence from the source rather
than on every other authority disagreeing, which is the footing this
project's own standard asks for.

+; RESOLVED 2026-08-22 (coordinator): the page IMAGE was rendered and read
+; (pdftoppm -f 48, the PDF page bearing printed folio 46). TWO findings.
+; FIRST, the pdftotext layer is FAITHFUL -- the printed book really does
+; carry "Missa pr., (omittuntur ps. Iudica me et Gloria Patri), Gloria,
+; sine Credo, praef. comm." under FERIA VI IN PASSIONE ET MORTE DOMINI, so
+; the adjacent-block-misread possibility named above is RULED OUT, not
+; merely unlikely.
+; SECOND, and this is what settles the adjudication rather than resting it
+; on external attestation: the SAME PAGE proves the compiler knew the
+; distinction and lost it here specifically. Its next entry, "4. Viol ...
+; SABBATUM SANCTUM", carries NO "Missa pr." line at all -- correctly, Holy
+; Saturday's own Mass being the Vigil's. The entry after it, "5. Alb DOM.
+; RESURRECTIONIS", carries a full one. So on one page the book omits the
+; Mass line where there is no Mass, and supplies one where there is; Good
+; Friday, which likewise has none, wrongly receives one. Its own Vespers
+; rubric on the same entry calls the day's rite "Actioni liturgicae
+; vespertinae" -- an Action, not a Mass -- contradicting the Mass line four
+; lines above it.
+; The line is also WORD-FOR-WORD identical to Holy Thursday's own on the
+; preceding page ("(omittuntur ps. Iudica me et Gloria Patri), Gloria, sine
+; Credo"), where every word of it is correct. A copied line, not a
+; considered statement.
+; Verdict unchanged (colitur), now on internal evidence from the source
+; itself rather than on "every other authority disagrees" -- which is the
+; stronger footing, and the one this project's own standard asks for.
