# Stripe Payment Overview

The Stripe Payment module provides a minimal, test-friendly billing facade and framework adapters
for health/metadata reporting, webhook wiring diagnostics, and safe configuration defaults.

## Capabilities

- Health + metadata snapshots exposing environment readiness (`has_api_key`, `has_webhook_secret`).
- Webhook diagnostics scaffolding for subscription and payment flows.
- Stable config defaults that can be overridden during generation.

## Architecture

- Core runtime facade provides `health_check()` and `metadata()` payloads.
- FastAPI adapter exposes router endpoints under `/stripe-payment/*`.
- NestJS adapter mirrors the same surface via a module/service/controller.

## Security considerations

This module may touch sensitive data or privileged actions depending on how it is configured.

- Security: store Stripe secrets in a secret manager and never log them.
- Threat model: validate webhook signatures and protect endpoints against replay attempts.

If you operate in a regulated environment, include a brief audit trail strategy (what you log,
retention, who can access).
