subscription.activated

When this fires

A subscription leaves a non-active state (trialing, paused, past-due) and transitions to active.

Required ability

project-subscription:view-any — token must carry this at mint time to subscribe an endpoint to this event.

Caveats

Distinct from subscription.created: created fires once on first persistence; activated fires on every transition into the active state thereafter.
Trial-to-paid transitions emit both subscription.activated and member.converted.

subscription.created — initial creation.
subscription.trial_started, subscription.unpaused — likely predecessors.
