Your point about the gap between clean testing environments and messy production reality really resonated with me. I experienced a structural version of this recently while building an n8n workflow. I deliberately prototyped the logic using a Form trigger because the payload was clean and flat, and all my edge-case tests passed. However, when I swapped it to a Webhook for production, the workflow failed silently. The business logic was intact, but the payload shape had changed (the data was now nested under a body object alongside HTTP metadata), so downstream nodes quietly stopped seeing the data they expected. It reinforced your argument about the need for early validation. I’m curious, for your 'Classification + Action Router' pattern, do you typically add an explicit data-normalization step right after the trigger to decouple the raw payload from the rest of the workflow logic?
