Live ops

live-ops owns event activation state. Gameplay systems keep ownership of their own rules; live configuration may select published variants but does not create hidden clocks or undocumented balance mutations.

Event contract

Every event publishes:

event ID
config revision
start/end and time authority
minimum/maximum compatible client when applicable
eligibility rule / cohort assignment
content/rule references
reward transaction identity and idempotent grant policy
fallback when config/content/service is missing
post-event state / cleanup
