Publication boundary: this is a synthetic redesign inspired by operational learning. It contains no employer workflow, real request, email, attachment, credential, internal identifier, database schema, or production connection.

Evidence you can inspect
An inactive, importable n8n workflow that requires no credentials.
Four fictional requests covering success, external ownership, high risk, and invalid input.
Designed, configured, tested, and documented by Luis Alfredo Báez Páez, with AI assistance during development and technical refinement. Problem definition, requirements, validation decisions, testing, and acceptance remained human-led.
