fix round 1: RG 110(c)'s ordering was inverted; M19 lacked an identity gate

RG 110(c), word for word: "quoties vero oratio unius Apostoli addenda
est ad modum commemorationis, huic orationi additur altera immediate,
ante omnes alias commemorationes." "Huic orationi" (dative, "to this
oration") refers to the trigger's own oration; "additur altera" means
the companion is added to it, i.e. follows it. "Ante omnes alias
commemorationes" governs the pair's position relative to other,
unrelated commemorations, not the pair's own internal order. The
previous build prepended the companion uniformly in both RG 110
shapes, citing this same clause for both -- correct for (a)/(b) (the
day's own oration, not a list member, has nothing to order against),
backwards for (c), where the trigger is itself a list member and the
companion belongs after it. Fixed in rg110_additions: shape (a)/(b)
still prepends; shape (c) now splices the companion in immediately
after its own trigger. Re-pinned the unit test that had asserted the
wrong order, and corrected both rows' comments to cite the clause that
actually governs each shape.

No layer in this codebase compares commemoration order: the lectio
differential never compares commemorations, the oracle sorts both
sides into a multiset, and the golden tests' own describe function
sorts its commemorations field too. Recorded as a new, permanent blind
spot in CLAUDE.md and the register, not merely fixed around -- the
admit_cases unit table is the only place order is asserted at all.

Re-measured the full blast radius against the same pre-change binary:
same 14,627 differing days, same four shapes and counts, confirming
the fix changed only the content of the 593 shape-(c) rows and nothing
else. Mutation-tested: reverting the splice back to a uniform prepend
reddens exactly the shape-(c) unit test; a new golden pin for a real
shape-(c) day (2004-02-22) stays green under the same mutation, living
proof that golden pins cannot see this axis, not merely a claim.

Separately, M19's own predicate checked a date and a diff shape but
not which candidate -- proved insufficient by fabricating a second,
bogus companion on 30 June and confirming the whole suite stayed
green. Fixed by requiring the admitted commemoration to be exactly
commemoration-of-st-peter, mirroring C16's own identity guard. Added a
golden pin for 30 June, the only assertion of that entry's identity
outside the allow-list.

Also: corrected a false claim in the task report that the electronic
transcription carries no corroboration of the Holy Name fallback --
its own table of contents does, at a line not checked on the first
pass. Added two further citations, both re-verified against the scan:
RG 17's own closing paragraph, settling the Sunday shape's Sunday-
exclusion at the rubric level rather than only in the propers; RG
124(c), which assigns red to 30 June by paragraph number rather than
by the generic apostle/martyr default. Noted the fragility of deriving
the Sunday shape's RG 109(a) privilege from a slug-substring match
rather than from a citation. Cosmetic: a stray blank line and an
indentation inconsistency.
