Proof: npm test (209/209) covers stale command expiry, bounded executor state, bounded strategy quote cache, bounded quote outcome refresh, and resource guardrails.
Assumptions: current DB pair config and armed state remain the operator-approved live trading controls; stale quote commands are unsafe to submit after their min_deadline_ms.
Still fake: quote outcomes still infer fills from inventory deltas rather than a venue-native terminal fill event.
Proof: Live investigation showed doran-1 entered NodeNotReady with kubelet SystemOOM and TLS/control-plane timeouts while near-intents-ingest, history-writer, and operator-dashboard were the largest Node memory consumers. This commit adds websocket publish backpressure for the raw quote firehose and pod memory guardrails for the affected services.
Assumptions: Dropping quote frames while Kafka publishing is backpressured is safer than allowing unbounded in-flight publishes to take down the single-node cluster; retained Kafka/Postgres history remains best-effort under overload until the platform has enough capacity for full raw retention.
Still fake: This does not add durable queue spillover for skipped raw websocket frames, does not resize the node, and does not prove fee-complete trading PnL.
