Rules derived from BC MCP API page development experience:
- api-page-flowfields-must-be-calcfields: FlowFields return empty on API
pages unless explicitly CalcFields'd in OnAfterGetRecord
- stored-derived-fields-must-not-be-exposed-directly: Stored fields updated
only via OnValidate triggers can be stale; recalculate live in OnAfterGetRecord
- api-page-key-fields-must-be-editable-on-insert: ODataKeyFields with
Editable=false are rejected as unknown properties on POST
- api-page-least-privilege-write-access: Create dedicated minimal pages per
write concern rather than widening general-purpose pages
- agent-must-not-write-business-process-status: Agents must only write
developer-tracking fields; business status fields affect invoicing/time registration
