Proof: Dashboard portfolio metrics now include DB-tracked USDC balances valued from live BTC/EUR and BTC/USDC reference prices, with regression coverage for the observed USDC inventory case.
Assumptions: USDC is cash-equivalent for valuation when a fresh BTC/USDC reference event is available; live trading safety remains governed by pair config and price route checks.
Still fake: Portfolio valuation still does not provide fee-complete realized PnL or generalized valuation for every imported non-stable asset.
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: npm test; node --test test/history-writer-static.test.mjs test/kafka-topics.test.mjs test/environment-status-history.test.mjs; node --check src/apps/history-writer.mjs.
Assumptions: Durable history consumers are idempotent by event_id, so from-beginning subscription is safe when a topic has no committed group offset.
Still fake: This protects durable event capture for repo-owned Kafka topics; it does not backfill events that were never published to Kafka.
