Caveats

Activation does not retroactively touch existing subscriptions on the plan; only checkout availability changes.
Frequent flipping is permitted but produces noisy timelines — use plan.updated for non-state edits.

plan.deactivated — paired transition.
plan.created — predecessor.
Plan events overview — back to family overview.
