Architecture¶
How DataQ is built, and the record of why. These pages are written for engineers evaluating, extending or operating the system.
-
System architecture
Component, sequence and entity diagrams, kept in sync with the code by a CI drift guard.
-
Decision records
Every significant design decision as a short ADR with context, options and consequences.
-
MCP tool design
Why every AI-facing tool states what it cannot see, and the audit criteria behind it.
-
Performance baseline
Measured throughput and memory per datasource, and the scan caps that protect the worker.
-
Incident evidence card
The payload every incident carries, and what is redacted before it leaves the database.
-
Contributing
Working agreements, quality gates and the per-PR workflow.
