Job flow 9 · task:mandate-reauth-reminder Diagram

Queued by: PaymentEventProcessor.handlePaymentFailed on the failure that moves a renewal to PAST_DUE when Razorpay's error description says the amount is above the mandate's maximum (isMandateLimitBreach). The subscription gets paymentFailureSubReason MANDATE_LIMIT_EXCEEDED, the normal grace jobs, and no automatic retry (the same charge would fail the same way).
Not queued for PENDING_REAUTH created by a price push at renewal; that path only gets the grace warnings and the one 'Payment Failed - Action Required' email from billingCycleWorker.
Two jobs: mandate-reauth-0-<sub> immediately and mandate-reauth-mid-<sub> at half the grace period (monthly: day 3; quarterly: day 7; yearly: day 15).
Email 'Payment Failed - Action Required': the subscription amount is higher than the authorized limit, re-authorize the mandate with a higher limit, N day(s) remaining; amount = the cycle's full price; link /portal/subscription (the Re-authorize Mandate / payment setup box).
