Merge branch 'ef-rg16a': RG 16(a), RG 111(b), RG 113, and commemoration identity

Closes the largest known-wrong-output item on record (RG 16(a): a Feast
of the Lord occurring on a II-class Sunday leaves the Sunday
uncommemorated -- 5996 wrong days over 1583-9999) together with RG
111(b)'s rank floor on the day it holds, and gives the oracle layer the
ability to compare commemoration identity rather than only presence and
count.

Also corrects a methodological defect that had produced wrong rulings in
both this project and its sibling: docs/research/ holds an electronic
transcription alongside two photographic scans, and the transcription
silently drops commemoration lines -- seven across the year. Reasoning
from its silence had convicted the oracle wrongly on 14 August and
ruled a genuine 9 August commemoration spurious. The scans are the
primary source; the rule is now recorded at the top of the register.

RG 113 replaces an alphabetical same-rank tie-break that had no
rubrical warrant. A bare Commemoratio has no row in RG 91's table at
all, so band no longer hands one the entry of a III-class universal
feast: 4451 days, all four reordered pairs verified against a
photographic scan, zero observed-day changes.

+
+   CORRECTED, fix round 1 (IMPORTANT finding, item 2): this pin used to
+   expect Pope Sixtus II et al. (6 August's own unrelated Class3 saint,
+   Commemoration_only) admitted as an ordinary commemoration in the freed
+   slot -- promoted from `colitur day`'s own actual output without
+   consulting either the primary text or the oracle first (the exact
+   vacuous-pin flavour the review caught, and this file's own header warns
+   against). Re-derived properly this time:
+   - PRIMARY TEXT: RG 16(a) itself says the winning Feast of the Lord holds
+     the Sunday's place cum omnibus iuribus et privilegiis -- WITH ALL the
+     Sunday's own rights and privileges. RG 111(b) is one of those: in
+     dominicis II classis, una tantum admittitur commemoratio, SCILICET DE
+     FESTO II CLASSIS -- a Sunday's own slot is reserved for a Class2
+     candidate specifically. The day is still a dominica II classis for
+     this purpose even though the Transfiguration, not the Sunday, is
+     [observed] -- so Sixtus (Class3) has no standing for the slot at all,
+     the same as on any other II-class Sunday (contrast
+     [test_ii_class_sunday_admits_only_ii_class_commemoration] above,
+     romanus, Class3, excluded the identical way on an ORDINARY II-class
+     Sunday).
+   - ORACLE, independently fetched (missalemeum's own /api/v5/calendar

+     2026-08-06 (a Thursday, no Sunday collision) -- Sixtus present in

+   proved this was vacuous by reversing admit's own dignity/precedence sort
+   (Rite_ef.Precedence_ef, so the engine admits the WORST candidate, an
+   outright RG 111 violation) and finding every assertion in this file
+   still green across all 730 days (see the perturbation record in the task

+   also compares WHICH commemoration is admitted, using two independent
+   signals from missalemeum's own JSON: the commemoration's title text
+   (English, exact string) and, for a sancti-origin commemoration, its own
+   [id]'s embedded rank digit (used only as a corroborating check, never as
+   the primary signal -- see [Comm_identity] below).
+
+   THE MAPPING, AND EXACTLY WHAT IT CANNOT RESOLVE: missalemeum identifies
+   a commemoration by an English TITLE string; colitur identifies one by a
+   SLUG. There is no hand-built slug<->title lookup table here -- colitur's
+   own {!Celebration.t}.names already carries an English name for every
+   SANCTORAL-origin celebration (bootstrapped from lectio's own English
+   titles, which verifiably match missalemeum's titles character-for-
+   character on every checked row), so the comparison reads that name
+   directly off colitur's own resolved output, the same field
+   test_differential.ml already treats as authoritative for OF/EF display
+   text. This resolves identity for every SANCTORAL-origin commemoration.
+   It CANNOT resolve a TEMPORAL-origin commemoration (an impeded feria, a
+   privileged Sunday, an Ember/Rogation day, etc.): {!Rite_ef.Temporal_ef}'s
+   own [build] never sets a celebration's [names] field (rite_ef/
+   temporal_ef.ml has no [en "..."] string anywhere in it), so every such
+   candidate's own title is empty on colitur's side -- there is nothing to
+   compare against missalemeum's title text, and no principled way to
+   invent one without duplicating missalemeum's own English-prose
+   convention ("Feria III after the I Sunday of Lent") as a second,
+   unverified source of truth. THIS CASE IS NEVER SILENTLY SKIPPED: see
+   [Comm_identity_unresolved] below -- it is counted, reported, and must be
+   named in the allow-list like any other difference, exactly the discipline
+   the brief demands ("a day whose commemoration cannot be matched must be
+   visibly counted and reported, not quietly passed").
+
+   Identity is only even ATTEMPTED once presence and count already agree
+   (both non-empty, same length) -- a cardinality mismatch is already
+   [Comm_presence]/[Comm_count]'s own business (see [diff_fields] below),
+   and comparing SETS of different size would just restate that mismatch
+   under a third name, not add information. Compared as a SORTED MULTISET
+   of titles, not a sequence: missalemeum's own [commemorations] array order
+   is not independently verified against RG 113's own "commemoratio de

+   1962 calendarium's own March table carries... 'Feria VI post dominicam I
+   Passionis: Commemoratio septem Dolorum B. Mariae Virg.'... a fixed
+   commemoration... EVERY year") -- confirmed real, and confirmed

+   `grep -B3 ... | grep -oP "rank Class\d" | sort | uniq -c` both give

+   for a [Commemoration_only] match is NOT itself uniform: of the 175
+   examined, 17 genuinely AGREE (oracle_rank = colitur_rank = 3, real
+   corroboration) and 158 show oracle_rank 4 against colitur's bootstrapped
+   3 -- CORRECTED after the first version of this comment overclaimed "id
+   consistently encodes 4 for every entry" from the 158-strong failure list
+   alone, before the 17 agreeing rows (then hidden inside a too-strict
+   assertion) were found. Two acceptable shapes, then, not one: either the
+   ranks genuinely agree, or the specific oracle=4/colitur=3 gap holds. This
+   is not evidence of a title-matching error, and not new: it independently
+   corroborates the register's own already-open item (§6, "Commemoration-
+   only entries' inferred STATUS, not only rank" -- Task 16's own data
+   audit already flagged these ranks as bootstrap inferences, never
+   individually Missal-verified). Auditing which of the 114 are genuinely
+   Class3 and which were silently defaulted to it is that item's own scope,
+   not this task's -- so rather than either asserting a false universal
+   equality (which fails on the 158 KNOWN, tracked, out-of-scope rows) or
+   silently dropping the check, this pins the discovered SHAPE itself:
+   every [Commemoration_only] match is EITHER a real agreement OR the known
+   gap, with no THIRD pattern -- a real, falsifiable claim (any other
+   combination would break it) that stays honest about what remains
+   unverified.
+
+   WHAT THIS DOES NOT PIN (coordinator finding 8, fix round 1, honestly
+   named rather than left implicit): the [oracle_rank = colitur_rank]
+   branch accepts ANY genuine agreement, including one this check cannot
+   independently verify is the CORRECT rank -- a regression that silently
+   flipped some entry's [rank] from [Class3] to [Class4] would land in the
+   agreement branch and pass cleanly if missalemeum's own id happened to
+   read 4 for that entry too (data drift on one side coinciding with data
+   drift on the other is not ruled out by this check, only coincidence
+   independent of any real cause is). This test pins "no third pattern
+   appears", not "every individual rank is correct" -- a narrower, still
+   genuinely useful claim (see the [> 50] population guard below, which
+   confirms the pinned shape is actually exercised at scale, not vacuously
+   true over an empty or trivial set), and this comment says so rather than
+   letting the assertion's own name imply more than it checks.
+
+   [Feast]-status candidates get the ORIGINAL, unrestricted check (any
+   disagreement at all is unexpected). CORRECTED (fix round 1, coordinator
+   finding 1): this comment previously claimed this branch was unreachable
+   in the 2026-2027 window (checked: 0) because its one candidate, Thomas
+   of Villanova on 22 September, was M17's own mismatch -- WRONG, once
+   traced further: M17 itself was wrong (see {!Precedence_ef.band}'s own
+   fidelity fix, register §6.1), and fixing it made 22 September resolve
+   cleanly on both sides, reachable here after all. Measured, not assumed:
+   22 Feast-status commemorations are now examined by this branch (not
