Author Common-of-a-Confessor-Not-Bishop Lauds/Vespers content

Proof content for the new Common-fallback mechanism, live-verified
against Divinum Officium (Monastic Tridentinum 1617): Lauds chapter/
responsory/hymn/versicle ("Jesu coróna célsior"), cross-checked
byte-identical between St. Louis's and St. Nicholas of Tolentino's own
days. Vespers bundle (hymn "Iste Conféssor Dómini sacrátus", reusing
the already-authored Matins hymn translation) sourced via the
reference engine's votive=C5 view instead of a real saint's own Second
Vespers, since every saint in this Common category has their own
Second Vespers permanently outranked by an adjacent fixed feast.

TODO.md records the fuller sourcing detail and the remaining open
Common categories.

+### Lauds/Vespers chapter-responsory-hymn-versicle bundle: rank-agnostic Common fallback (2026-08-25)
+
+**Bug fixed**: St. Louis (2026-08-25, `common-of-a-confessor-not-bishop`, Simplex, wins
+outright) was showing the plain ferial chapter/hymn at Lauds instead of his own Common's —
+`hours/lauds.ts`'s `resolveOffice` only substituted a feast's own proper bundle
+(`lauds-{part}-<id>.yml`), gated at duplex-majus+ (piggybacking eligibility on the Lauds
+psalmody-override table, itself majus+-only by design), with no Common-level fallback at all.
+Same gap existed in `hours/vespers.ts`'s identical `resolveOffice`. Fixed by adding
+`resolve-common.ts`'s `resolveOfficeBundle`: tries the winner's own proper bundle first, then
+falls back to their Common's bundle (`SaintRecord.common`, the same id driving the day
+collect — not `minorHoursCommon`, a deliberately different id for P/T/S/N), eligibility tested
+rank-agnostically via the existing `getMinorHourOverrideId` (any sanctoral winner, not just
+duplex-majus+) — a simplex feast's own or Common's chapter/hymn is real, distinct liturgical
+content, not something only strong feasts are entitled to. Vespers' own chapter lookup
+(`vespersCapitulumForOverride`, which already falls back to the byte-identical Lauds capitulum
+file when no separate Vespers one exists) is passed in and reused unchanged for both the
+proper and the Common id.
+
+**Proof authored**: `common-of-a-confessor-not-bishop`'s full Lauds bundle (chapter, short
+responsory, hymn "Jesu coróna célsior", versicle) and Vespers bundle (chapter reused from
+Lauds, short responsory, hymn "Iste Conféssor Dómini sacrátus" — Latin/English text reused
+verbatim from the already-authored Matins hymn file, same Monastic-track recension — versicle),
+live-verified against Divinum Officium (Monastic Tridentinum 1617). Lauds content cross-checked
+byte-identical between St. Louis's own day and St. Nicholas of Tolentino's (`propers: null`,
+clean year), confirming genuine shared Common content. Vespers content, unusually, had to be
+sourced via the reference engine's `votive=C5` ("Commune Confessoris non Pontificis") view
+instead of any real saint's own rendered Second Vespers — every one of this Common's 4 real
+saints (St. Louis, St. Francis, St. Dominic, St. Nicholas of Tolentino) turned out to have
+their own Second Vespers permanently outranked by a fixed adjacent feast (St. Zephyrinus's
+First Vespers, SS. Placid and Companions', Our Lady of the Snows', the Nativity-of-the-BVM
+octave, respectively) — a structural pattern for this category, not a query mistake. Also
+corrected a wrong lead from earlier in this investigation: `CommuneM/C4a.txt`'s file-inheritance
+structure (`@CommuneM/C4`) initially looked like it meant Confessor-Not-Bishop reuses
+Confessor-Bishop's Office bundle wholesale, but the reference engine's own votive-office naming
+(C4 = "Confessoris Pontificis", C5 = "Confessoris non Pontificis", C4a = "Doctoris Pontificis" —
+an unrelated category with a superficially similar filename) settles that these are two
+genuinely separate Common categories with their own distinct hymns ("Jesu Redémptor ómnium" vs
+"Jesu coróna célsior" at Lauds).
+
+`npm test` (471 tests), `tsc --noEmit` both pass. **Still open**: the other 10 Common
+categories in the "still open" list above have no Lauds/Vespers bundle authored yet either —
+same honest incremental-content gap, now on a mechanism that no longer silently drops to the
+ferial default for any rank.
