Separate Before Serializing Shared State
Trigger
When concurrency, locks, queues, shared state, or complex coordination are being considered.
Rule
Eliminate unnecessary sharing or partition ownership before adding locks, queues, or coordination.
Application
- Name the concrete decision this principle changes.
- Apply the rule to that decision, not as a decorative citation.
- Prefer evidence from the current repository/runtime over generic preference.
- If the principle conflicts with an explicit user constraint, keep the constraint and state the tradeoff.
