…scount - In-app cancel now runs through a 3-step modal: required reason (Polar's cancellation enum) + optional comment -> pause offer (1-3 months, billing stops at period end, events keep flowing) -> one-time 30%-off-for-12-months discount -> frictionless cancel. - Polar SDK 0.48.1 -> 0.49.0 for subscription pause/resume support. - New subscription states: pausing (active + pause scheduled) and paused (blocks dashboard with a resume prompt; ingestion continues as before). - Webhook syncs pause fields + customer cancellation reason/comment, so portal-driven cancels are captured too. - New org columns: subscriptionCancelReason/Comment, subscriptionSaveDiscountAppliedAt, subscriptionPauseAtPeriodEnd, subscriptionResumesAt. - create-save-discount script provisions the reusable Polar discount (POLAR_SAVE_DISCOUNT_ID). - Checkout guard: paused subs must resume before changing plans (prevents a second Polar subscription).

📝 WalkthroughWalkthroughSubscription billing now supports cancellation reasons, retention offers, subscription pauses, scheduled resumes, immediate resumes, and save discounts. The changes update persistence, payment operations, API procedures, webhook synchronization, subscription state handling, and billing UI controls. ChangesSubscription lifecycle
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The cancellation flow can consume the one-time discount for subscriptions that are not active, and a failed provider update can still mark the offer as used. Customers could therefore lose an eligible discount or remain scheduled for cancellation after using it; these cases should be fixed or explicitly accepted before merging.

- Around line 202-220: Update the pauseSubscription mutation to validate the

discount.
- Around line 69-78: Update the subscription guard around subscriptionStatus and
subscriptionPauseAtPeriodEnd to reject both currently paused subscriptions and
active subscriptions scheduled to pause before entering the plan-change path.
Preserve the existing TRPCBadRequestError and message behavior for either paused
state.

Require an active subscription before claiming the save discount.
This mutation only checks subscriptionId. A canceling, pausing, or paused subscription can claim the one-time offer and call Polar. A cancellation-scheduled subscription can then retain its cancellation while the discount becomes permanently unavailable.
Reject every state except organization.subscriptionState === 'active' before the conditional update.
Proposed fix

throw new TRPCBadRequestError('Organization has no subscription');
}

Recover a claimed discount when the process exits.
If the process exits after updateMany succeeds and before Polar confirms the update, subscriptionSaveDiscountAppliedAt remains set. Later requests return “already been used” although Polar never received the discount.
Store a recoverable pending claim and reconcile it with an idempotent provider operation or an outbox worker.

Why
The in-app cancel button fires immediately: no confirmation, no reason capture, no alternative. We learn nothing from most cancellations, and customers who only need a temporary break have no option besides leaving. This PR turns cancellation into a survey → pause → discount ladder.
