Job flow 7 · task:grace-warning Diagram

Queued together with final-deactivation every time a grace period starts: startPaymentGracePeriod (renewal declined → PAST_DUE; no card or no price at renewal → PAST_DUE; Razorpay pushed price above the mandate → PENDING_REAUTH), beginCancellationGracePeriod (period end with cancel flag → CANCELLED), and trial-ending / sub-finalization (→ ENDED).
Two jobs: grace-warn-3d-<sub> at grace length − 3 days and grace-warn-1d-<sub> at grace length − 1 day; a warning whose time is already past is not queued. Grace length: monthly 7, quarterly 15, yearly 30 days (STRIPE_*_GRACE_PERIOD_DAYS), free trial 7 days after trialEnd.
Still in grace: status must still be ENDED, CANCELLED, PAST_DUE or PENDING_REAUTH. A payment that settles also removes these jobs (cancelAllSubscriptionLifecycleJobs).
