# Acme Monorepo

This repository contains all services and packages for the Acme platform.

## Packages

- **api** — Core REST API service
- **web** — Customer-facing React frontend
- **payments** — Payment processing service
- **ml** — Machine learning inference service
- **shared** — Shared utilities and types
- **admin** — Internal admin dashboard
- **notifications** — Email/SMS notification service
- **analytics** — Analytics event pipeline

## Getting started

Install dependencies: `npm install`
Run all services: `npm run dev`
Run tests: `npm test`

# API Package

The core REST API built with Express and TypeScript. Exposes endpoints consumed
by the web frontend and external partners.

## Development

Start the dev server: `npm run dev` (runs on port 3001)
Run tests: `npm test`
Run linter: `npm run lint`

## Environment variables

Copy `.env.example` to `.env` and fill in values. All required variables are
documented in `.env.example`.

## Database migrations

Run pending migrations: `npm run migrate`
Roll back last migration: `npm run migrate:rollback`

# Payments Package

This module handles all credit card processing and billing operations for the
Acme platform using Stripe.

## PCI-DSS compliance

**This package is in PCI-DSS scope.** All changes to this package must be
reviewed by the security team before merging. Open a PR and add
`@acme/security` as a required reviewer—do not merge without their approval.

## Running tests

Tests in this package must be run against the PCI sandbox environment. The
flag `--pci-sandbox` must be passed to the test runner for all local test
runs:

Note: CI enforces this for the deployment pipeline, but **local test runs do
not automatically apply this flag**. Omitting it will run tests against
real Stripe test keys, which is not permitted under our PCI controls.

## Stripe configuration

Set `STRIPE_SECRET_KEY` and `STRIPE_WEBHOOK_SECRET` in your `.env` file.
Use sandbox keys for local development (prefixed with `sk_test_`).

# ML Package

This package provides PyTorch-based model inference for Acme's recommendation
and ranking features.

## GPU memory management

Before running any training scripts locally, you must set the following
environment variable to prevent CUDA out-of-memory errors:

If this is not set, training runs will frequently OOM and crash mid-epoch,
especially on machines with less than 24 GB of VRAM. This is not enforced
by any config file—you must set it manually in your shell or `.env`.

## Model weights

Trained model weights are **not stored in this repository**. They live on the
shared dev server at `/mnt/ml-storage`. You will need access to the dev
server to run inference locally. Contact the ML team to be added to the
access list.
