docs: document template.yaml and repo structure in README
Daily security sweep flagged that the README omitted template.yaml (the
SAM stack) as an existing component. Add a Repository Structure section
naming template.yaml and the src layout.

Also fix a related setup gap: the Slack webhook Secrets Manager secret
(SlackWebhookSecretArn, required by slack.py via SLACK_WEBHOOK_SECRET_ARN)
was not covered by the setup instructions.

# Afi Backup Monitor
![CI](https://github.com/Sea-Haven-Industries/afi-backup-monitor/actions/workflows/ci.yaml/badge.svg)

![AWS SAM](https://img.shields.io/badge/AWS-SAM-FF9900?logo=amazonaws&logoColor=white)
![Slack](https://img.shields.io/badge/Slack-integration-4A154B?logo=slack&logoColor=white)
AWS SAM stack with two Lambda functions that integrate the Afi.ai backup API with Slack.
## Functions
**afi-auto-protect** — Runs weekly. Compares tenant resources against active protections and automatically applies the configured backup policy to any unprotected users. Posts a summary to Slack.
**afi-health-digest** — Runs weekly. Pulls task statistics (last 7 days), storage quotas, and resource coverage, then posts a formatted digest to Slack.
## Architecture
- **Runtime:** Python 3.12 (arm64)
- **Shared Layer:** Afi API client + Slack webhook helper
- **Secrets:** Afi API key and Slack webhook URL stored in AWS Secrets Manager
- **Scheduling:** EventBridge cron rules (default: Mondays 10am ET)
## Repository Structure
```
template.yaml # SAM stack: Lambdas, shared layer, IAM, EventBridge schedules
src/
auto_protect/app.py # afi-auto-protect handler
health_digest/app.py # afi-health-digest handler
shared/python/ # shared layer
afi_client.py # Afi.ai backup API client
slack.py # Slack webhook helper
```
Deployment parameters (secret ARNs, tenant ID, policy ID, schedules) are defined in
`template.yaml` and supplied at deploy time via `samconfig.toml`.
## Documentation
The canonical map of Sea Haven's AWS infrastructure lives in Confluence. This project's `afi-backup-monitor` stack is represented there as a Mermaid subgraph.

## Setup
1. Store the Afi API key and Slack webhook URL in Secrets Manager:
```bash
aws secretsmanager create-secret --name afi-api-key --secret-string "appkey-YOUR_KEY"
aws secretsmanager create-secret --name afi-slack-webhook --secret-string "https://hooks.slack.com/services/YOUR/WEBHOOK/URL"
```
2. Update `samconfig.toml` with your Secret ARNs (`AfiApiKeySecretArn`, `SlackWebhookSecretArn`), Tenant ID, and Policy ID.
3. Build and deploy:
```bash
sam build && sam deploy
```
## Manual Testing
```bash
aws lambda invoke --function-name afi-auto-protect --payload '{}' /dev/stdout
aws lambda invoke --function-name afi-health-digest --payload '{}' /dev/stdout
```
