Architecture Decisions

LuckyPlans uses ADRs to document technical choices that shape product behavior, historical correctness, or operational cost.

When to write an ADR

  • when simulation behavior changes materially
  • when contract versioning rules change
  • when a new platform architecture is introduced
  • when deployment or security posture changes in a lasting way

ADR template

  • Status
  • Context
  • Decision
  • Consequences
  • Alternatives considered

See the ADR pages in this section for concrete examples tied to the current product direction.
