Idempotent Redundancy
When adding redundant paths (fallbacks, belt-and-suspenders), make them idempotent.
Pattern
Redundancy without idempotency causes loops, churn, or data corruption.
DO
- Use `_is_merge: true` for Braintrust updates
- Check if value exists before writing (fallback only if missing)
- Use atomic write/rename for file operations
- Make reconciliation steps safe to run repeatedly
DON'T
- Write unconditionally in fallback paths
- Allow multiple writers to overwrite each other
- Fire "repair" actions that can trigger more repairs
