+### Fixed (Billing guide matches the current deployment — `bugfix/docs-billing-current-deploy`)
+
+- **`docs/BILLING.md` described an old AWS layout**, with CloudFront, an ALB and the `app.tamci.app`
+  domain. The MVP now runs on `reqsai.tech`, where Caddy serves the web and proxies `/api/*` from one

+- **The guide now says where the MVP host keeps the Stripe settings:** the infra vault and
+  `app_api_settings`.
+- **The Stripe prices to create are USD 49 (Pro) and USD 149 (Enterprise)**, the amounts the app
+  displays (`BILLING_*_AMOUNT_CENTS`). The guide said USD 29 and USD 99.

 ### Fixed (Jira OAuth callback in the dev profile — `bugfix/jira-dev-callback-url`)
