From 0764c3d43b86299e915e2880a97e455e1389c55e Mon Sep 17 00:00:00 2001 From: Manas Srivastava Date: Fri, 29 May 2026 16:33:11 +0530 Subject: [PATCH] fix(billing): detect live-key-in-dev + surface traffic_env on /checkout (BUG-P112) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit QA team reported that visiting /app/checkout/?plan=hobby while unauthenticated landed at a LIVE-mode Razorpay subscription page (sub_Sv96Mt2n8nnDYL). BUG-P111 was the SPA-side root cause (now fixed in instanode-web fix/checkout-auth-gate-and-cache-reset); BUG-P112 is the server-side belt-and-braces: an operator pointing a non-prod deployment at a LIVE Razorpay key would let any caller reaching this handler mint a REAL subscription on the prod Razorpay account. This change adds two coupled guards to CreateCheckoutAPI: 1. trafficEnv() + detectBillingMisconfiguration() classify the configured RAZORPAY_KEY_ID via its documented prefix convention (rzp_live_* → production, rzp_test_* → test). When ENVIRONMENT != "production" but the key is live, the handler short-circuits with 503 billing_misconfigured + a clear operator agent_action — BEFORE the create-subscription call. Razorpay's dashboard never sees the phantom subscription; the operator gets a single actionable error. The guard is intentionally placed BEFORE the existing billing_not_configured branch: a live-in-dev pairing is dangerous even if RAZORPAY_PLAN_ID_TEAM happens to be unset on that environment. 2. Successful 200 responses (both fresh-create and F7 reuse paths) now include traffic_env: "production" | "test". Agents and the SPA can branch on the field without ever seeing the raw key value. SECURITY CONTRACT: the actual RAZORPAY_KEY_ID is NEVER echoed in ANY response body — only the derived two-state field. Multiple tests pin this constraint. OpenAPI doc updated to match (rule 22). ### Surface checklist (rule 22) - api/plans.yaml not affected - common/plans/plans.go defaultYAML not affected - api/internal/handlers/openapi.go UPDATED (new 200 field + 503 description) - instanode-web/.../CheckoutPage.tsx UPDATED in companion PR (web) - content/llms.txt not affected (response shape change only) - dashboard upgradeCopy.ts not affected Tests added (all checkout tests pass — `go test ./internal/handlers/ -short -run TestCheckout`): - TestBillingCheckout_DetectsLiveKeyInDevEnv (full env × key matrix) - TestBillingCheckout_TrafficEnvDerivation_OnlyProductionOrTest - TestBillingCheckout_ResponseIncludesTrafficEnv (DB-required — happy path) - TestBillingCheckout_ResponseTrafficEnvIsTestForTestKey (DB-required) - TestBillingCheckout_TrafficEnvSurfacesOnReusePath (DB-required — F7 reuse) The 'NEVER leak the RAZORPAY_KEY_ID' security contract is asserted via json.Marshal scanning of every response body in every relevant test.
