feat(ef): the Seven Sorrows of Passion Friday, and M16 reversed

Not the II-class feast of 15 September, which colitur has had since the
bootstrap, but the other Seven Sorrows: the movable commemoration of
Passion Friday, of which colitur had no trace at all.

The 1962 calendarium lists it at the foot of March, below the fixed
dates, exactly where a movable entry belongs (LT.txt:5056): "Feria VI
post dominicam I Passionis: Commemoratio septem Dolorum B. Mariae Virg."
Note the word -- Commemoratio. Under the 1960 rubrics it is a
commemoration, not a feast, so it can never win the day.

Friday after Passion Sunday I is Easter-9, confirmed independently by
both dates the oracle allow-list already disputed: Easter 2026 is 5 April
and M16's date is 27 March; Easter 2027 is 28 March and M13's is 19
March. It could not be built before Date_spec grew Easter_offset -- the
same wall Rogation Wednesday hit, and the second entity that work has now
unblocked.

M16 is re-adjudicated and its verdict REVERSED, from missalemeum to
colitur. The entry existed because colitur admitted St John Damascene
where missalemeum showed the Seven Sorrows, colitur having no candidate
to admit. Both streams now name the Seven Sorrows and that mismatch is
gone. What remains runs the other way, and the rubric is explicit: RG
111(d) admits TWO commemorations on a III-class day, RG 113 puts the
seasonal one first, and RG 114 omits only what exceeds the number. 27
March 2026 is a III-class privileged Passiontide feria; colitur admits
exactly two, the Seven Sorrows and John Damascene, a real III-class
universal feast genuinely falling that day. missalemeum admits one and
reports John Damascene as displaced, dropping a commemoration the rubric
allows.

That makes four divergences adjudicated colitur where missalemeum drops
or mis-assigns something -- Monica's Epistle, Perpetua's Common, Christ
the King's week, and this. Recorded as a pattern rather than four
coincidences: the oracle stays a comparison instrument, but its error
rate on adjudicated cases is no longer negligible.

M13 is untouched and stays open: 19 March 2027 is a different dispute,
whether Joseph is displaced from Passion Friday at all, and on a I-class
day RG 111(a) admits one privileged commemoration which the feria takes.

Blast radius, full 1583-9999 sweep against the pre-change binary: 7874
days, every one carrying the new commemoration, zero unclassified, line
counts equal both sides.

Register: section 6.12.
