sync-agent-is-idempotent
IN premise
Calling `sync_agent` twice with identical data produces the same database state; the second call returns zero adds, removes, and updates — a no-op by design.
Summary
Running the sync agent on the same data a second time changes nothing — it detects that everything is already up to date and skips all writes. This matters because it means the sync process is safe to retry or re-run without risking duplicate entries, accidental deletions, or unnecessary churn in the database.
Dependents
These beliefs depend on this one:
- sync-is-safe-for-automated-reconciliation — `sync_agent` can be safely re-run on any schedule — idempotent execution with cascade structure preservation means repeated automated synchronization never corrupts outlist-based justification hierarchies or produces accumulating side effects.
