Completeness: 6/10 \u2014 happy path only, no tests, N+1 query and WebhookDispatcher bypass remain as known debt.\n\n\u2705 Surgical change \u2014 easy to review, easy to revert if the feature flag needs to roll back\n\u2705 Fixes the one non-negotiable blocker: SQL injection. Email errors can no longer cascade to HTTP 500 and trigger Stripe retries\n\u274c Zero automated tests on a payment flow \u2014 regressions will surface in production, not CI\n\u274c N+1 order-fetch loop stays; WebhookDispatcher bypass stays as architectural debt"

          "description": "Everything in A, plus: register the handler through the existing WebhookDispatcher module instead of bypassing it. Completeness: 7/10 \u2014 happy path + architectural correctness, still no test coverage.\n\n\u2705 Eliminates the architectural fragmentation \u2014 future Stripe event types plug into the dispatcher naturally\n\u2705 SQL injection fixed, email bounded \u2014 all of A's must-fixes, plus namespace consistency\n\u274c Still no automated tests for the payment flow; CI cannot catch regressions on this path\n\u274c Requires reading WebhookDispatcher internals before implementing \u2014 slightly wider blast radius"

          "description": "Everything in B, plus: unit + integration tests for the handler, fix the N+1 order-fetch with a bulk query, move the notification email to async delivery (queue or background job). Completeness: 10/10.\n\n\u2705 Zero silent failures \u2014 every path is tested, observable, and bounded. Payment flows have zero defect tolerance\n\u2705 The extra scope over A is ~25 min of CC time. With AI coding, \"do it right\" costs nearly the same as \"do it quick\"\n\u274c Async email delivery requires confirming whether a queue or background-job infrastructure already exists\n\u274c Largest diff of the three \u2014 more review surface, though each piece is individually straightforward"
