007: Architecture

  • Type: Architecture
  • Status: Planned
  • Date: YYYY-MM-DD
  • Author(s) / Deciders: System architects and lead developers
  • Question: How is the system decomposed into components, data flows, and directory structures, and which diagrams document its design?

Context

Define the high-level system boundaries, technology stack, module layout under source/, and visual diagrams so contributors understand how data and control flow through the system.

Required Visualizations

  1. UML Use-Case Diagram: Map actors to top-level system interactions.
  2. Data-Flow Diagram (DFD): Trace how inputs are ingested, transformed, stored, and emitted across boundaries.

Optional Visualizations (If Necessary)

  • Class Diagram: Include when complex domain hierarchies or interface contracts need explicit visualization.
  • Object Diagram: Include when runtime object graphs or ownership lifetimes require concrete snapshots.

Requirements and Restrictions

  • Tech Stack & Runtime: Primary programming language(s), build toolchain, and runtime environment.
  • Directory Layout: Organization of modules inside source/ and test suites.
  • External Boundaries: Databases, IPC mechanisms, network protocols, or FFI boundaries.

Alternatives

  • Monolithic vs. Modular / Layered: Compare architectural styles considered for this project and why the rejected structures did not fit.

Decision

Describe the chosen architecture, directory structure, and embed the Mermaid UML Use-Case and Data-Flow diagrams below.

Consequences

Positives

  • Visual diagrams and explicit module boundaries reduce onboarding time and prevent accidental coupling.

Negatives

  • Diagrams must be updated alongside structural refactors to prevent documentation drift.
