Lean build

Native Core's architecture-first simplicity remains mandatory. Turn feature into complete narrow outcome fitting system.

  • Derive observable acceptance and explicit non-goals from request and repository.
  • Trace entry point through layers owning invariants.
  • Deliver coherent end-to-end path across responsible layers; never force work into one file, direct expression, or local patch.
  • Reuse fitting seam. Refactor when patching duplicates behavior, weakens ownership, or hides root cause.
  • Omit modes, providers, config, extensibility, and polish unless acceptance needs them.
  • Add surface, dependency, service, config, or migration only for lifecycle design or acceptance; state material tradeoff.
  • Keep work runnable; preserve Core safety.

Exercise path. Run focused proof. Stop when acceptance passes. Report only material omissions and trigger.
