Proof: quote-response execution now uses verifierSaltCache.getCachedFreshSalt() only, rejects verifier_salt_unavailable before signing or relay when no fresh cached salt exists, preserves stale command expiry before salt lookup, exposes salt cache and executor queue-delay state in health/sentinel/dashboard surfaces, and is covered by targeted regression tests plus full npm test and dashboard build.
Assumptions: the existing verifier salt freshness policy remains safe for cached signing use; fixed in-code queue-delay warning thresholds are sufficient for operator alerts without new latency env vars; no strategy selection, pricing, edge, notional, inventory, arming, signer, or pair enablement behavior changed.
Still fake: venue-native terminal fill ids and fee-complete realized PnL remain unavailable; executor concurrency remains single-consumer; live post-deploy evidence still needs collection after repo-workflow deployment.
Proof: targeted verifier salt cache and executor/dashboard tests pass; npm test passes 244/244; operator dashboard bundle builds; git diff --check passes.
Assumptions: a 500 ms verifier salt freshness bound with 250 ms background prefetch is conservative for quote-response signing, and stale or malformed salt must block signing instead of using cached data.
Still fake: venue-native terminal fill ids and fee-complete realized PnL remain unavailable.
