A high-traffic UI flow produces inconsistent ordering between initial load and refresh. The affected area is DOM event flow.
Repair the DOM event flow command handling implementation so it accepts first operations, recognizes safe repeats, and rejects key reuse with a different payload.
Evidence
- Affected surface: Web platform / DOM event flow.
- Observed failure family: enforce idempotent operations.
- Scope policy: tenantId must equal tenant-primary.
