Conversations/messages first-class module

Classification

Conversations/messages is a reusable first-class BuildWithHQ runtime module. The current Capability/Support handbook records the Phase 11 first-class module set as completed implementation evidence.

Shared first-class module contract

• Use universal RecordId conventions wherever the module represents business objects.
• Enforce SaaS/AppAccount/DataRole/location/field permissions through canonical secured procedures/services.
• Participate in record relations, activity/history, favorites, dynamic fields, search, workflows, and AI/MCP only where those capabilities are applicable to the module.
• Browser or AI callers use canonical module APIs; they do not perform direct table DML.
• AI/MCP access never widens the caller’s normal authorization envelope.

Module purpose

Reusable secured conversation threads and messages that can link communication directly to other business records.

Directory purpose

Keep this module’s architecture, API contracts, stored-procedure references, UI/runtime behavior, tests, support troubleshooting, MCP tools, and future module-specific knowledge together in this directory.
