Per direct instruction, and explicitly framed as this project's own
departure from Monastic 1617 itself: within Dec 26-30 inclusive (exactly
one real Sunday falls somewhere in that window every year), whichever
date is the actual Sunday always wins as Nat1-0 outright, with no rank
check at all -- even Stephen/John/Holy Innocents (Duplex II. classis)
get fully displaced, not just commemorated. The displaced saint isn't
commemorated in place either; he reappears in full as Dec 30's own
winner instead (the block's one date with no fixed saint of its own).
Rank never matters for this rule -- confirmed with Becket (Semiduplex)
transferring the same way as the Duplex-II-classis saints.
This deliberately diverges both from what Monastic 1617 itself does on
Dec 26-29 (live-verified two commits ago: the saint wins there, Sunday
merely commemorated) and from the general privileged-sunday transfer
rule elsewhere (which only transfers ranks below duplex-majus and
commemorates everything else in place) -- this window transfers every
rank and commemorates nothing in place, a genuinely new, third
behavior specific to this 5-day block.
Implemented as calendar/index.ts's applyChristmasOctaveSunday, a
narrowly-scoped layer in the same spirit as applyMarianSaturday/
applyChristTheKing, rather than by changing the shared
decideOccurrence/transfer machinery every other Sunday relies on. Dec 31
and everything outside Dec 26-30 is untouched -- St. Silvester still
beats the Sunday there via the plain, unchanged ordinary-sunday rule.
Verified against all five possible Sunday positions within the window
(Dec 26/27/28/29/30) plus the "nothing displaces anything" control case,
each with its own dedicated test in the new
tests/calendar/christmas-octave-sunday.test.ts. Updates two existing
tests whose assertions were correct under the old rule and are now
superseded specifically within this window (Stephen/Innocents no longer
win their own Sunday-collision dates there) while confirming the
underlying ordinary-sunday rule is still live and real outside it (Dec
31/St. Silvester).

christmastide's Sunday was coded privileged-sunday (Advent's own tier),
which live-checking against the reference engine shows is wrong: on
every one of the three real collision dates (St. Stephen/John/Holy
Innocents, all Duplex-II-classis, falling on the Sunday within the
Octave) the saint wins outright and the Sunday is merely commemorated --
the reverse of what privileged-sunday would produce (Sunday stays
primary, saint just gets a nod). St. Silvester (plain Duplex, Dec 31)
confirms the same live. Reclassified to ordinary-sunday, which matches
all four checked cases: Duplex+ wins outright (Stephen/John/Innocents/
Silvester), Semiduplex still transfers off the Sunday rather than
winning (St. Thomas Becket, unaffected by the fix either way), and a day
with no saint at all resolves to the Sunday cleanly.
Found while pulling christmas-octave-sunday's own Benedictus antiphon
from the reference engine's dedicated Tempora/Nat1-0 proper and noticing
this app's own occurrence resolution didn't match what the live engine
showed for the Sunday's real collision dates.

Adds calendar/octaves.ts: a lookback over the past week collecting every
octave (sanctoral or temporal) still active on a date, stacking multiple
at once (Christmas + St. Stephen + St. John + Holy Innocents all
commemorated together within the Christmas Octave). Declared via an
optional `octave` field on a saint's own record or a new small
TemporalFeastRecord (calendar/temporal-feasts.ts) for temporal ids like
Christmas/Pentecost that didn't have a metadata record before -- data-
driven per user design discussion, with `{ enabled: true }` alone using
sensible defaults (8 days, semiduplex threshold) so a minimal declaration
works without authored content.
Wired into resolveDay as a post-processing layer: doesn't change how a
single day's own precedence contest is decided, just adds commemorations
for active octaves and occasionally overrides the winner when the
occurring saint doesn't clear the strictest active octave's threshold.
Populated so far: St. Lawrence's own octave (the one that repeatedly cost
real saints their spot in August), the three Comites Christi octaves
(Stephen/John/Innocents -- Thomas of Canterbury deliberately excluded,
per discussion), and Pentecost's (duplex threshold, user-specified).
Pentecost's octave offsets are also removed from temporal-categories.yml's
privileged-feria-major classification, letting a real candidate reach the
new octave layer instead of being transferred away first -- with the
side effect that Pentecost's own Ember Saturday no longer forces a
transfer (a sub-threshold saint is now commemorated in place instead, see
tests/calendar/transfer.test.ts's updated case). Assumption, Nativity
BVM, Immaculate Conception, and All Saints' own octaves are not yet
populated with octave data -- deliberately deferred to a follow-up pass.

10 collects, 5 antiphons -- including backfilling the pre-existing
Immaculate Conception entry. St. Damasus's collect is Latin-only (no
English translation exists in the reference source at all); a few
others (All Saints, Bibiana, Immaculate Conception) needed their English
read directly from the raw source file after the live query's English
side either omitted the Oratio translation or rendered the wrong Marian
feast's text -- caught by cross-checking, not assumed.
