Schema: HolidayCalendarV3 (ID: 9012)

The holiday calendar of record: one calendar's content - its weekend, the variance-time shape of its trading day

and its dated exceptions - keyed by that content.

THE KEY IS THE CONTENT. calendarKey is a ContentKey tagged Calendar over the SHA-256 of the canonical form (CALENDAR_CONTENT_KEY.md),

byte 0 dropped for the tag. A loader hashes what it built and publishes; two producers building

the same calendar publish the same row, and nobody mints an id. A row is immutable: a changed calendar is a

new row under a new key, and a deleted row is content withdrawn.

THE NAME LIVES ELSEWHERE. ScheduleDefinitionV3 (9057) points a product group at a key and carries the

Manual / Loader / Bridge ladder; CalendarDefinitionV3 (9009) is the human registry of adopted names (XCME,

USNY) pointing at their current key. The compiled tables are the floor beneath both and keep their names.

desc is the producer's memo - 'union of XAMS, XEUR', 'XCME 2026 refresh' - readability, never identity.
