+- **Investor Test Results:**
+  1. Trust with money? **NO** — Stripe webhook incomplete, Pro payment flow is fragile
+  2. Data loss? **No** — backups running ✅
+  3. Free tier abuse? **Mitigated** ✅
+  4. Key recovery? **Yes** ✅
+  5. False features? **Clean** ✅
+- **Critical Finding:** Stripe webhook handler only processes `customer.subscription.deleted`, NOT `checkout.session.completed`. Pro key creation relies entirely on user visiting the success page. If they close the browser during Stripe checkout redirect, they pay but never get their Pro key. `STRIPE_WEBHOOK_SECRET` is empty in the container env.
+- **Spawned Sub-Agents:**
+  1. **Backend Dev (Stripe)** — Investigating webhook config, checking Stripe API for registered endpoints, reviewing handler code. In progress.
+  2. **Backend Dev (Bugfix)** — Fixing BUG-033 (OpenAPI spec accuracy) and BUG-032 (mobile terminal gap). In progress.
+- **Assessment:** NOT launch-ready. The Stripe webhook gap is a real business risk — customers could pay and not receive their Pro key. This must be fixed before launch.
+- **Budget:** €181.71 remaining, Revenue: €0
+- **Status:** NOT launch-ready. Sub-agents running, results pending.
+- **Next:** 1) Fix Stripe webhook (add checkout.session.completed + configure webhook secret). 2) Register webhook endpoint in Stripe. 3) Full E2E Pro payment test. 4) Close BUG-032/033.
