Fields

Field	Args	Type	Description
id	—	ID! required	—
name	—	String! required	—
displayName	—	String	—
countryOfBirth	—	String! required	—
sex	—	HorseSex	—
colour	—	HorseColour	—
yearBorn	—	Int	—
sire	—	HorseRef	Sire reference — canonical horse when linked (REQ-025), else name-only.
dam	—	HorseRef	Dam reference — canonical horse when linked (REQ-025), else name-only.
damSire	—	HorseRef	Dam-sire reference — canonical horse when linked (REQ-025), else name-only.
progeny	—	[Horse!]! required	Progeny — this horse’s IMMEDIATE offspring: canonical horses whose sire OR dam resolves to this horse (POD-355, REQ-027). Does NOT include the dam-sire (maternal grandsire) edge — those are a further generation, not direct offspring. Derived read-only from the breeding graph; each entry is a full canonical Horse so the Relatives surface can reuse the registry’s horse table columns (name / country / year-born / sex / sire / dam) and click through to each offspring’s profile. Empty when this horse has no recorded offspring. Bounded by name to a sensible cap (damline / full pedigree traversal are a later refinement, OQ-A12).
bred	—	String	—
officialRating	—	Int	—
rprRating	—	Int	—
topspeedRating	—	Int	—
retired	—	Boolean! required	—
deceased	—	Boolean! required	—
breeder	—	Breeder	—
version	—	Int! required	Optimistic-locking version (participants.version) — pass as expectedVersion on updateHorse.
sportId	—	ID! required	—
createdAt	—	DateTime! required	When the participant row was first inserted (participants.created_at).
aliases	—	[ParticipantAlias!]! required	Records merged into this canonical via the M22 merge flow (REQ-009).
disciplineRatings	—	[DisciplineRating!]! required	Most-recent official rating per discipline (Turf-Flat / Jump / All-Weather), derived from run history.
careerWinnings	—	[MonetaryAmount!]! required	Total prize money this horse has earned across its career (POD-539), one entry per currency. Summed from the same per-run derivation as Runner.winnings, so the total always equals the sum of the per-run figures. Prize breakdowns mix currencies across territories and no FX conversion is applied, so amounts are reported per currency and never combined into one figure. An absolute career figure — only runs that actually earned contribute, so it does not move with the history-list status filter. Empty when the horse has no recorded winnings. Ordered by raw amount descending purely for stable display; because no FX is applied, the order is not meaningful across currencies (a larger raw number in one currency is not “more” than a smaller one in another). Do not infer relative value from position.
silkHistory	limit: Int	[HorseSilkHistoryEntry!]! required	Silks this horse has worn across its career, most recent first (POD-83). Mirrors the top-level horseSilkHistory query.
trainer	—	Trainer	Current trainer (POD-615) — the open horse_trainer_history period (ended_on IS NULL). A horse has at most one current trainer; null when none is recorded. Distinct from the per-race snapshot exposed on Runner.trainer.
ownership	—	[Ownership!]! required	Current owners (POD-615) — all open horse_ownership_history periods (ended_on IS NULL). Owners may be concurrent (a syndicate), so this is a list; empty when none is recorded. Distinct from the per-race snapshot on Runner.ownership.
upcomingEntryCount	excludeRaceId: ID	Int! required	Count of this horse’s active future entries in the next 7 days (“runs again”) — excludes finished races and inactive entries. Batched per request, so a race card can show the indicator for every runner in one round trip. > 0 means the horse is declared to run again soon; use entriesForParticipant(futureOnly) for the detail list. Pass excludeRaceId (the race being viewed) so an upcoming race doesn’t count its own entry — keeping the count aligned with the detail list.
