To generate a build-ready architecture plan, use an engineering review workflow that takes your locked product direction and outputs Mermaid diagrams, a data flow map, a state machine, and a test matrix for implementation planning.

A pre-implementation engineering architecture spec includes architecture diagrams, data flow maps, core flow state machines, sync vs async boundary decisions, a failure mode inventory, a trust boundary assessment, and a test matrix.

Map trust boundaries and failure modes by running a post-direction engineering review that forces architecture planning, producing a trust boundary map and a comprehensive failure mode inventory before coding starts.

Yes, you can use Mermaid diagrams for state machine and data flow mapping during system planning to visually lock the technical direction and define buildable architecture boundaries.

The best way to create a test matrix from a validated product direction is to run an engineering review that processes the locked requirements and outputs a structured test matrix alongside architecture diagrams.

You need a state machine and sync vs async boundary assessment when your product direction is locked and you must define buildable technical specs, data flows, and failure modes before implementation coding begins.
