[creed]'s correct [false] answer for them rests entirely on an unstated property of {!Rite_ef.Temporal_ef}: no ferial-origin office it ever builds carries [subject = Lord] or [subject = Bvm] at [Class2] (RG 475(c)'s own rank guard), and none carries a slug on [RE.creed_apostle_slugs] (RG 475(e), which has no rank guard at all). This test asserts that property directly against real Temporal_ef output, rather than leaving it asserted only in prose, so a future Temporal_ef change that breaks it fails HERE loudly instead of silently changing the Creed. Two real, harmless, already-documented exceptions are excluded from the [subject] checks rather than papered over: the Sacred Triduum ([subject = Lord], [Class1] -- verified in temporal_ef.ml's own [triduum_names] branch) and the votive Office of the BVM on Saturday, RG 91 entry 27 ([subject = Bvm], [Class4] -- {!TE}'s own [is_bvm_saturday] citation). Neither can ever reach [creed]'s 475(c) branch: the Triduum is caught earlier by the explicit feria-I-classis check (its own [Class1] is not [Class2]), and the BVM Saturday Office is [Class4], not [Class2], so 475(c)'s own rank guard excludes it regardless of subject. Excluding them here is not a loophole in the test -- it is the precise boundary of what RG 475(c) actually reads, confirmed rather than assumed by restricting the [Lord]/[Bvm] checks to exactly [Class2] (RG 24's own II-class population) and [Class3] (RG 25's III-class population), the two ranks a real feria can carry that are NOT already handled by an explicit branch or a rank mismatch. The apostle-slug check has no such carve-out: it is asserted for every ferial-origin day of every rank, matching 475(e)'s own unguarded text. A THIRD exception -- not anticipated when this test was first written, found by actually running it, not by inspection -- had to be excluded from the POPULATION itself, not from the subject checks: RG 17(a)'s own "secus die 2 ianuarii" fallback (2 January, only in a civil year with no 2-5 January Sunday) is a genuine FEAST, [subject = Lord], [Class2], sitting outside {!TE.named}'s table for a purely architectural reason (temporal_ef.ml's own citation: that table's shape cannot express a fallback conditional on a per-year fact) and not always a Sunday either, so neither of [is_ferial_origin]'s two filters caught it on the first run -- it failed on 1584-01-02 before {!is_holy_name_fallback} below was added. Left in as evidence the sweep has real teeth rather than trimmed from the span: excluding a genuine mistaken positive by name, once found, is the correct fix; narrowing the span to dodge it would not have been. A day is "ferial-origin" here iff {!TE.named} returns [None] for it (nothing in the fixed/movable table of named feasts, vigils and octave days claims it), it is not a Sunday (RG 21's own definition: "Nomine feriae intelleguntur singuli dies hebdomadae, praeter dominicam" -- every day of the week EXCEPT Sunday), and it is not the RG 17(a) fallback date just above. *) let contains_substring ~needle haystack = let nl = String.length needle and hl = String.length haystack in let rec loop i = (i + nl <= hl) && (String.sub haystack i nl = needle || loop (i + 1)) in nl = 0 || loop 0 (* RG 17(a)'s own "secus die 2 ianuarii" fallback (temporal_ef.ml's own citation on [holy_name_fallback_date]): a genuine FEAST, [subject = Lord], [Class2] -- legitimately outside {!TE.named}'s table only for an architectural reason (that table's bare [Date.t -> ... option] shape cannot express a fallback conditional on a per-year fact, [holy_name_sunday y = None]), never a ferial one, and it is not always a Sunday, so the weekday filter below does not catch it either.
