Closes #524

Changes

feat: issue #524 pr-519-adds-stripe-webhook-event-idempot (agent task liancebot524)

Acceptance Criteria

PR #519 adds Stripe webhook event idempotency to prevent duplicate billing events. Verify:

  1. Duplicate webhook delivery with same event ID is idempotent (second returns 200, no side effect)
  2. Concurrent processing of same event ID is handled with database-level locking or unique constraint
  3. Event processing order is maintained (or out-of-order is handled gracefully)
  4. Failed event processing is retryable (not marked as processed on error)
  5. Test coverage includes: duplicate event, concurrent event, invalid event ID

Post verification results as PR comment.

PR #528 Merge-Readiness Assessment: NO-GO

Summary

This PR claims to implement Stripe webhook event idempotency (per issue #524) but contains no functional code changes. The only files modified are auto-generated .tldr/cache/call_graph.json and .tldr/languages.json. The webhook handler at packages/api/src/routes/billing.ts:67-131 is unchanged from main.

Verification Results

Criteria Status Details
Duplicate events not processed twice FAIL No idempotency check exists. The handler processes every webhook delivery regardless of whether the same event.id was already handled.
Idempotency check before DB writes FAIL No check is present. The switch/case at lines 88-103 dispatches directly to handlers (handleCheckoutCompleted, handleSubscriptionUpdated, etc.) with no prior dedup guard.
200 returned for duplicate events FAIL Since there is no dedup logic, duplicate events are fully reprocessed. If processing succeeds, 200 is returned (but with duplicate side effects). If it fails, 500 is returned.
Test suite passes PASS npm test exits 0 (Jest finds no tests in scope — API tests use bun:test and are excluded by config). No new idempotency tests were added.

What's Missing

To properly implement webhook idempotency, this PR needs:

  1. A processedWebhookEvents table (or similar) with a unique constraint on eventId to track processed Stripe event IDs
  2. An early-return guard in the webhook handler that checks event.id against this table before the switch/case dispatch, returning { received: true } with HTTP 200 for duplicates
  3. Atomic insert-then-process — mark the event as claimed (e.g., INSERT with ON CONFLICT DO NOTHING) before processing, so concurrent deliveries of the same event are also handled
  4. Rollback on failure — if processing fails, the event should NOT be marked as processed so Stripe can retry
  5. Tests covering: duplicate event returns 200 with no side effect, concurrent same-event handling, failed processing is retryable

Verdict: NO-GO

This PR should not be merged. It contains only cache file regeneration and no implementation of the idempotency feature described in the title and issue #524.
