test(differential): C14 and C15 closed -- only slug vocabulary remains

lectio adopted the last two Missal corrections colitur argued:

  C14  3 -> 0   RG 96(a)/97/98. lectio resolved each impeded I-class feast's
                transfer independently, so in 2008, 2035 and 2046 St Joseph and
                the Annunciation both walked onto the Monday after Low Sunday
                and Joseph, losing there, was observed on no day of those years
                at all. It now resolves the year's transfers as a set: the
                Annunciation takes the Monday as its sedes propria, Joseph the
                Tuesday.
  C15  7 -> 0   The Holy Family propers' own 13-January rubric, "sine
                commemoratione Baptismatis D.N.I.C.". lectio kept the Baptism
                as the observed office on all seven such years in 2005-2050.

Those were the last two BEHAVIOUR classes. What is left is C1 (138) and C6
(119), both pure slug vocabulary.

Measured across the whole fixture, applying only the season normalisation the
test already applies: 579 of 16801 days differ, and every one of them differs
on the SLUG ALONE. Zero days differ on season, rank, colour, Epistle or Gospel.
(The test's own norm_slug table already maps 322 of the 579; the 257 left are
C1 and C6. The field profile is the same either way.)

So the two engines now agree on every liturgically meaningful field on every
day of 2005-2050. The residue is what the two projects call things --
ef-christmas-2-friday against ef-time-after-epiphany-1-friday for the same day,
same Mass. Aligning it means renaming lectio's slugs, and those are keys: its
lectionary, clectio's generated tables and any user overlay are built on them.
Left as vocabulary rather than forced.

Fixture refreshed against lectio e713da2; 13 rows changed, colitur agrees with
all of them. 24 divergence classes at the start of this work, 2 now.

 Fixture: lectio-ef-2005-2050.txt
+Task: 2026-08-18, refresh after lectio adopted two further Missal corrections
+(RG 96(a)/97/98 transfer collisions, and the Holy Family propers' own
+13-January omission of the Baptism).
+
+Produced by the sibling project ~/git/projects/lectio at commit:
+  e713da2 fix(ef): two I-class feasts can no longer transfer onto the same day
+SHA-256: 2e9c5761e7e5ccee4b5be096e8727d07a2e67dd9523a897f9aa73407ddf1e350
+
+13 rows changed against the previous fixture (bac0aacfaa67db0f6f9ae45f1295f831f62bb35a6e2a8e8c72503b2b26e1a8a8):
+  - 7 rows, 13 January in 2008/2013/2019/2030/2036/2041/2047: lectio kept the
+    Commemoration of the Baptism as the observed office on a 13 January that is
+    itself the Sunday after Epiphany. The Holy Family Mass propers say "sine
+    commemoratione Baptismatis D.N.I.C." -- the Baptism is omitted, and the day
+    is the Holy Family. lectio now agrees with colitur on all seven.
+  - 6 rows, 2008/2035/2046: St Joseph and the Annunciation, both impeded by an
+    early Easter, both transferred onto the Monday after Low Sunday, where
+    Joseph lost and vanished from the year (he showed only as "+joseph-..." in
+    the Annunciation's commemoration tail). RG 96(a) gives the Annunciation a
+    sedes propria on that Monday; Joseph now takes the Tuesday. lectio agrees
+    with colitur on all six.
+
+Both corrections run colitur -> lectio, not the other way: colitur argued them
+from the Missal and lectio adopted them. On these 13 days the Divinum Officium
+lineage no longer holds, the same way the eight earlier corrections broke it.
