// PRO-launch broadcast ramp runner. Wakes once a day at 13:00 UTC

// overnight bounces and complaints have flowed back via the Resend
// webhook). The action no-ops when no ramp is configured, the ramp
// is paused, kill-gated, or the prior wave hasn't settled yet —
// see `convex/broadcast/rampRunner.ts` for the full state machine.
// Daily retention prune for the plan-limit tables. apiUsageRollups gains a row
// per user per hourly scan and apiPlanLimitNotices accumulates superseded rows,

// INTEL_HISTORY_RETENTION_DAYS out by `ingestedAt` in bounded per-run
// batches that self-drain. Also drains expired retraction tombstones
// (#5743) in the same pass, by `retractedAt` — a handful of hand-created
// rows do not justify a second scheduled function. See `prune` in
