A device lifecycle boundary exposes stale data when network and local state disagree. The affected area is deep link router.
Repair the deep link router command handling implementation so it accepts first operations, recognizes safe repeats, and rejects key reuse with a different payload.
Evidence
- Affected surface: iOS / Swift / deep link router.
- Observed failure family: enforce idempotent operations.
- Scope policy: retained must equal true.
