Summary

• Approval resume resolves the parked call through an exact ContextStore lookup with no history-heuristic fallback
• Expired, consumed, or duplicate typed approval decisions are discarded before parsing and never become ordinary input
• A retry after an observed acceptance reuses it exactly once, and the delivery guard lives under single ownership in delivery-queue

Verification

• Approval, reactor-acceptance, director, delivery, and keeper suites pass on every lane
• bun run check passes on each lane branch (exit 0)
