Guide
Command Repository
The Command Repository is the relational store behind the Command Router. It is the authoritative history of what was asked of a device, when, how many times we tried, and how it ended. Every status the API reports comes from here.
Storage profile
PostgreSQL, single logical database. Commands and their attempts are retained for 90 days for audit and debugging, then archived out of the hot path.
Data model
The schema is built around the command and its lifecycle: the command itself, each delivery attempt, the terminal result, and the (potentially large) payload split into its own table. The ERD is embedded on the Overview tab.
