Custom business-rule inventory

This inventory starts with order import and carrier assignment because their rules influence downstream logistics. It is a coverage backlog, not an exhaustive list of every custom rule across Logidav or the whole Menzzo ecosystem. A source-reviewed page describes a pinned code revision, not the deployed state or a business-owner approval.

Area	Entry point or evidence	Current documentation	Next investigation

How to extend this inventory

For each workflow, identify the user or scheduled trigger, entry point and actual call chain; record condition precedence, inputs, state changes, events, external effects, failure/retry behavior, and the source commit. Link the rule page from its system, flow and troubleshooting entry points. Mark unreviewed branches and configuration as unknown, and separate code evidence from observed production behavior. Have the business owner validate the intended policy where the code has hard-coded thresholds or identifiers.
