docs(L3): the bissextile rubric is scan-verified after all

L3 recorded that the leap-year shift rested on the LT.txt transcription
alone, the scans having been searched without result. It is in scan2.txt
at 3050-3058, OCR-damaged but unmistakable.

The earlier search missed it for a findable reason, now written into the
entry: the OCR mangles the saint and the keyword alike -- "Matthue",
"Cabrielis", "bi&sextili" -- so neither "Matth" nor "bissext" matches. It
turns up on the undamaged phrase "februarius est dierum".

Transcription and scan now agree, which makes this two witnesses of one
document rather than one. Still one document; the citation continues to say
calendarium rather than RG, because a calendarium footnote is what it is.

SCAN-VERIFIED 2026-08-22 (coordinator), upgrading this entry's own earlier caveat that it rested on the transcription alone: the footnote IS present in the photographic scan at docs/research/scan2.txt:3050-3058, OCR-damaged but unmistakable -- \"In anno bi&sextili mensis februarius est dierum 29^ et festum S.

Transcription and scan agree, so the rule now rests on two witnesses of the SAME document rather than one -- still one document, which is why the citation says calendarium and not RG.")

  (note "colitur has NO bissextile-shift rule anywhere (grepped lib/rites/rite_ef/*.ml and data/ef/*.sexp for \"bissext\"/\"leap\": zero hits outside a code comment naming the saint, and the rules-register.md itself is silent on it too) -- St Matthias stays fixed at 24 February every year, leap or not. 2024 is a leap year: colitur's own [matthias] entry (Class2, an Apostle, RG91 entry 16 -- verified from the table itself to genuinely OUTRANK entry 18's privileged Ember-Saturday-of-Lent feria, so colitur's RANKING logic is not at fault here) WINS 24 February 2024 outright in colitur's output, correctly saying the Creed per RG475(e)'s Apostle clause. The Ordo shows no St Matthias anywhere near this date at all: 24 February 2024 is titled plainly \"EMBER SATURDAY of LENT\" (No Cr) and 25 February 2024 (a Sunday, 2nd Sunday in Lent, I class) is titled plainly \"2nd SUNDAY in LENT\" (Cr, but via RG475(a)'s own Sunday clause, not RG475(e)) -- consistent with Matthias having correctly MOVED to the 25th and then lost outright to the I-class Sunday there (RG91 entry 6 over entry 16), never even surviving as a commemoration (an I-class Sunday's own admission cap, RG111, is tight enough to exclude an ordinary II-class saint entirely -- the same shape already established for RG16(a)-adjacent cases elsewhere in this project). Both the 24th and 25th sides of the Ordo's silence are explained by ONE root cause (the missing shift), not two independent gaps -- a coherent, single-cause account, not a coincidence. BLAST RADIUS, roughly measured (a throwaway domain sweep, tools/probe_matthias.ml, run once for this task and not committed): of 2 041 leap years in 1583-9999, colitur observes [matthias] on 24 February in 1 650 of them -- an UPPER BOUND on how many years this gap could affect (some of those 1 650 years may see IDENTICAL final output either way, e.g. if Matthias would also win on the 25th against whatever competes there that year; a precise count needs the shift actually implemented, which is out of this task's own no-lib-changes scope). The Gabriel/27-28 February sibling shift is not witnessed by this fixture at all (no divergence on either date in this window) but is the same root cause and would need the same fix.")
