   English existed but was jarringly modern next to everything else's
   archaic register — reworded to match, marked `draft`).

+  St. Thomas Aquinas, the Forty Holy Martyrs, St. Gregory the Great
+  (translated, source had no English — the "non Angli sed Angeli" antiphon),
+  St. Joseph (corrected). St. Frances of Rome left `missing`: Simplex rank,
+  and March 9 always falls within Lent every tested year (2026-2035) — she
+  structurally can never win her own day outright under this app's own
+  calendar rules, so there's no live-rendered antiphon to source at all.
+- **April-December (87 saints): not started.**
 - **~52 temporal entries: not started.**
 - **94 `propers: null` saints: not started** — need a collect authored (a
   bigger, separate task) before an antiphon id even has anywhere to attach.
