Proof: Live investigation found the executor could stay disconnected from the solver relay after websocket error without close; relay client now reconnects after error and request timeout covers connection wait. Added regression coverage and npm test passes.
Assumptions: Historical relay OK responses were technically accepted and mostly not filled because they were not selected or settled, while the current disconnected relay state was a repo-side runtime bug affecting new submissions.
Still fake: Venue-native terminal fill events, fee attribution, realized per-trade PnL, and full inventory-skew strategy controls remain incomplete.
