Deliberate Omissions

Things an automation roadmap usually includes that were left out on purpose:

Omitted	Reason
n8n’s built-in AI and agent nodes	Convenient, and they put the model call where you cannot validate, version, meter, cache or test it. Step 7 explains the trade in full. Use them for a throwaway; not for something a client pays for monthly.
A cloud-hosted automation platform	Faster to start and cheaper to run, and it makes Ridgeway impossible. Self-hosting is the differentiator that lets you serve the clients who pay retainers. Step 2 says plainly when the hosted option is the right advice.
Writing your own workflow engine	Tempting after two weeks with someone else’s. It is a year of work to reach where n8n already is on connectors, triggers and retries, and none of that year teaches anything this material is about.
A message queue between n8n and your service	n8n has queue mode and retries. A broker in the middle is a third thing to run and monitor on a stack whose largest cost is already the server.
Fine-tuning a model per client	The prompt, the schema and the field descriptions are where behaviour is shaped here, they change in minutes, and they are inspectable by the client.
A full fairness or bias audit	Step 12 ships a near-identical-pair test, an input allow-list and an audit trail. A complete audit is a specialist discipline with its own methodology and, for a real engagement, its own budget. Claiming this material delivers one would be dishonest.
Legal advice on data protection	The material covers the technical shape — redaction, inference location, retention, what the ledger stores — and says explicitly that the contractual answer is a conversation with the client’s own advisers.
A managed observability platform	Step 13 covers what they do and when to adopt one. At this size the ledger is a table in the database you already run, and some self-hosted options want several times the memory of this entire stack.
Multi-tenant SaaS packaging	Turning three client automations into a product is a different business with different problems. This material is about delivered engagements.
Kubernetes and horizontal scaling	Step 15 deploys to one small host. The bottleneck is a third-party API and a human in a sign-off queue.

If someone tells you this roadmap is incomplete without one of these, ask them what their automation does when the model changes and nobody deployed anything.
