    Why you care
    The handler trusts the request body before checking Stripe's signature.
    Evidence
    Signature verification is missing on the payment success path.
    What to do
    Verify the webhook signature before activating a subscription.

Your AI can build the app. Who checks the app?

Generated code can be correct one file at a time and still fail as a product. The missing layer is understanding how code, services and customer outcomes connect.

AI builds

  • UI
  • API calls
  • Database queries
  • Checkout flow

AI does not know

  • Payment authenticity
  • Tenant isolation
  • Failure handling
  • Customer consequence

Passing checks do not mean the product works.

Security scanners, uptime tools and tests each see one layer. Intersite follows the complete path from code to service to customer outcome.

What the product can still do

3 business risks

  • Checkout can activate without proof of payment

    ↳ stripe/webhook.ts:61

    Revenue at risk

  • A signed-in user can cross a tenant boundary

    ↳ projects_select_policy

    Customer data exposed

  • A failed magic link still returns success

    ↳ auth/send-link.ts:38

    Users locked out

Every finding connects evidence to a concrete failure mode—not another dashboard alert.

From change to consequence.

Intersite doesn't stop at a file or alert. It follows the path to the customer and business outcome.
