Proof: history-writer now adds a repo-owned live evidence consumer group for normalized quotes and trade decisions while the existing durable group continues replaying retained backlog, so current maker timing and strategy truth can be persisted without abandoning old rows.
Assumptions: duplicate inserts are safe through existing event_id primary keys and bulk insert conflict handling; this changes only persistence catch-up behavior, not strategy decisions, relay submissions, pair enablement, edge, notional, inventory, arming, or response policy.
Still fake: venue-native terminal fill ids and fee-complete realized PnL remain unavailable; older normalized quote and decision backlog still depends on the durable replay group draining over time.
Proof: history-writer now runs multiple members in the existing durable consumer group so normalized quote, decision, command, result, inventory, and price topics can be assigned across workers while preserving existing group offsets and durable table writes.
Assumptions: three in-process durable group members stay within the existing service resource envelope and improve catch-up without changing strategy decisions, relay submissions, pair enablement, edge, notional, inventory, or arming behavior.
Still fake: venue-native terminal fill ids and fee-complete realized PnL remain unavailable; historical backlog catch-up still depends on live Kafka/Postgres throughput.
Proof: raw quote persistence now uses a dedicated history consumer group so raw quote firehose volume cannot starve durable normalized quote, decision, command, result, and outcome evidence topics in the main history-writer group.
Assumptions: raw quote persistence can join live in a dedicated group without changing event schemas or strategy behavior; no live pair, edge, notional, inventory, arming, or response-policy settings are changed.
Still fake: venue-native terminal fill ids and fee-complete realized PnL remain unavailable; historical backlog catch-up still depends on Kafka and Postgres throughput after deployment.
Proof: History-writer now writes routed event batches with one bulk insert per table, preserving decision and normalized quote history while reducing Kafka lag that delayed durable strategy decision rows.
Assumptions: Kafka message order within a topic partition remains sufficient for durability; environment status events keep their dedicated dedupe path; this change does not alter strategy, edge, notional, inventory, arming, or relay submission behavior.
Still fake: Venue-native terminal fill ids and fee-complete realized PnL remain unavailable; historical decision rows can still lag until the deployed batch writer drains existing backlog.
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.
