+## Quick Start for AI Agents
+
+**patchman-engine** is the backend for Red Hat Insights patch management: a REST API and background workers that evaluate which advisories and package updates apply to registered systems. See [README.md](README.md) for user-facing setup.
+
+### Authoritative Documentation
+
+| Topic | Location |
+|--------|----------|
+| Architecture and components | [docs/md/architecture.md](docs/md/architecture.md) |
+| Database layout | [docs/md/database.md](docs/md/database.md) |
+| Local dev, tests, OpenAPI | [README.md](README.md) |
+| Commits, PRs, contribution style | [CONTRIBUTING.md](CONTRIBUTING.md) |
+
+Prefer these sources over guessing when behavior or schema matters.
+
+### Code Discipline
+
+- Match existing **Go style**, package layout, and patterns in the touched area.
+- Keep changes **minimal** and scoped to the task; avoid drive-by refactors.
+- When touching the REST surface or request/response types, consider **OpenAPI** regeneration and any contract consumers.
+
+### Where to Look in the Tree
+
+| Area | Typical paths |
+|------|----------------|
+| HTTP REST API | `manager/` |
+| External messages | `listener/`, topic names in code and `conf/` |
+| Evaluation | `evaluator/`, topic names in code and `conf/` |
+| Advisory sync | `tasks/vmaas_sync/` |
+| Migrations | `database_admin/migrations/` (verify naming against existing migrations) |
+| Database schema and SQL | `database_admin/schema/` |
+| Containers and local orchestration | `docker-compose.yml`, `docker-compose.test.yml`, `Dockerfile*` |
+| Scheduled jobs | `tasks/` |
+| Admin REST API | `turnpike/` |
+| Platform services mock for development and testing | `platform/` |
+

+### System Upload Flow
+```
+Inventory Upload
+    ↓
+[platform.inventory.events] Kafka Topic
+    ↓
+Listener Component
+    ↓ (updates system_inventory, system_patch, system_repo)
+    ↓
+[patchman.evaluator.upload] Kafka Topic
+    ↓
+Evaluator-Upload Component
+    ↓ (calls VMaaS /updates)
+    ↓ (updates system_advisories, advisory_account_data)
+    ↓
+[platform.notifications.ingress] (optional)

+[platform.inventory.host-apps] (optional)
+```
+
+### Advisory Sync Flow
+```
+Scheduled Job Trigger
+    ↓
+VMaaS Sync Component
+    ↓ (calls VMaaS /errata, /pkglist, /repos)
+    ↓ (updates advisory_metadata, package, repo)
+    ↓
+[patchman.evaluator.recalc] Kafka Topic
+    ↓
+Evaluator-Recalc Component
+    ↓ (bulk re-evaluation of affected systems)
+    ↓
+Database Updates
