START WITH THE FAILURE PATH
Useful guidance should change a design decision.
Each guide explains one operating problem, a practical control model, common failure patterns, and a review checklist. The examples connect to verified portfolio implementations. They do not represent production or client outcomes.
01 / RELIABILITYAutomation rescue
An automation is not reliable until failure has somewhere to go.
Classify failures, separate retryable from terminal work, prevent duplicate side effects, and leave operators with an actionable state.
- Failure taxonomy
- Retry boundaries
- Idempotency
- Run evidence

02 / HUMAN CONTROLAI workflow pilot
Put human approval where consequence meets uncertainty.
Design a review boundary that gives a person enough evidence to make a decision instead of becoming a rubber stamp.
- Risk triggers
- Review packets
- Decision audit
- Queue failure

03 / TRUSTData monitoring
“No change” and “no data” are different business events.
Make source freshness, completeness, schema, and availability part of the report so a clean layout cannot hide a broken input.
- Source contracts
- Trust states
- Claim withholding
- Lineage

04 / DELIVERY CONTROLn8n production review
Make production review evidence-based.
Check the workflow contract, duplicate safety, AI decision boundary, credentials, run evidence, rollback, and handoff before live connection.
- Contracts
- Side effects
- AI review
- Release gate

05 / BACKEND HANDOFFFastAPI + PostgreSQL
Make every important state change explainable.
Review contracts, migrations, token and tenant boundaries, replay-safe writes, version conflicts, audit evidence, environment gaps, and operating ownership before transfer.
- Migrations
- Authorization
- Idempotency
- Audit evidence

06 / AGENCY HANDOFFn8n delivery partner
Delegate implementation, not production control.
Prepare one bounded workflow brief, sanitized evidence, explicit write permissions, failure behavior, a human release gate, and an operator-ready handoff package.
- Safe brief
- Access boundary
- Release gate
- Runbook
