Patch cycles are ~6 weeks, so a span over 180 days previously indicated
a misread year. However, real year-long events exist in this domain:
Genshin's anniversary 5-star selection runs 336 days (2025-10-22 to
2026-09-23), correctly dated on its wiki, and Fire Emblem Heroes runs a
seven-month new-player banner (docs/SOURCES.md § 12b).
Widening the ceiling to 365 days admits genuinely year-long events while
still catching misread years, which place the end 12 months out (span +
~365, or 405+ days for a 6-week event).
Update test/adapters/game8.test.ts duration test, AGENTS.md domain rules,
and docs/INGESTION.md sanity checks.
