Example document — replace with the design of a real component. This mirrors documentation/templates/design.md: behaviour only, no code blocks; diagrams must be Mermaid or ASCII art.

Responsibilities

Is responsible for:

  • Maintaining a running integer total as values are added.

Is NOT responsible for:

  • Persistence, concurrency, or input parsing (callers handle those).

Component Details

Part A — Accumulation

Holds a single integer total. Adding a value increases the total; resetting returns the total to zero. The operation is deterministic and allocation-free.

Interfaces

Provided

Interface Purpose Contract
Accumulator Add / read / reset a total Total reflects the sum of inputs since the last reset
