TEST REPORT: Subscription Billing Kit (for Stripe) v1.0.0

Run from a clean unzipped copy of the dist zip (fresh npm install / pip install). Started 2026-10-17 06:15:04 BST (UTC+01:00), finished 2026-10-17 06:15:07 BST (UTC+01:00) (times from date at run time). Box: Linux, Node v24.22.0, Python 3.13.5.

Result: 15/15 passed = 12 unit tests + 3 schema checks against stripe-mock v0.206.0. The TypeScript typecheck is clean. Important: the 3 schema checks run against stripe-mock (Stripe's open-source mock server, which validates request parameters against Stripe's OpenAPI spec). They do not run against real Stripe test mode. Nothing in this product has been run against real Stripe test mode. Skip behaviour: if stripe-mock isn't listening on port 12111 (or STRIPE_MOCK_PORT), those 3 checks are skipped, not failed. Confirmed in this run: without stripe-mock the result was 12 passed, 3 skipped, 0 failed.
