Clean code: production contracts

Composition roots, context ownership, package APIs and exact time/money contracts.

  1. A composition root makes lifetime and cleanup visible

    Construct dependencies once and make their ownership and shutdown order explicit.

  2. Context is a cancellation contract, not a bag of dependencies

    Propagate request cancellation while giving detached work an explicit owner and deadline.

  3. Package APIs should reveal their change boundary

    Use narrow consumer contracts and tests that make accidental coupling visible.

  4. Time and money need units and presence in their types

    Separate durations, instants and exact amounts instead of passing ambiguous numbers.
