Regalia Slots API

v0.0.0-beta.11 - Fix load crash from duplicate trigger registration

Eleventh beta of Regalia Slots API for Minecraft 1.21.1 / NeoForge 21.1.249 (Java 21). beta.9 and beta.10 crash on load in any pack that reaches the curios:equip_curio trigger without a datapack override; every user of those builds should update.

Fixed

• Crash during mod loading (IllegalStateException: Adding duplicate value '…EquipCurioTrigger@…' to registry, from MappedRegistry.register in RegisterEvent). beta.9 registered curios:equip_curio with the same EquipCurioTrigger object already registered as regalia_slots_api:equip_curio. Vanilla MappedRegistry dedupes by value identity and rejects the second key, aborting the whole mod-loading phase.

Technical

• EquipCurioTrigger now has two instances — INSTANCE (regalia_slots_api:equip_curio) and CURIOS_COMPAT_INSTANCE (curios:equip_curio).
• Runtime triggers fan out through a private fire(...) that notifies the advancement listeners of both instances, so criteria authored under either id still fire on a curio equip. No behaviour change for regalia_slots_api:equip_curio advancements; curios:equip_curio advancements now both load (beta.9) and trigger (this release).

Notes

Regalia Slots API is a library. It adds no content on its own — install it only as a dependency of another mod that requires it, on both client and server. Incompatible with the real Curios mod (shared curios mod id); install one or the other. LGPL-3.0-or-later; the full licence text ships in the jar.
