- Compliance: return Uuid::nil() + warn! when features disabled instead
of random untraceable UUIDs (SOX, MiFID II, position monitoring, best
execution analysis)
- Audit queue: change fallback path from /tmp/ to /var/lib/foxhunt/,
upgrade fallback log from info to warn for alerting visibility
- Enhanced ML: wire get_ensemble_vote gRPC handler to real ensemble
coordinator instead of hardcoded [0.1, 0.2, -0.05, 0.8] features
- Paper trading: change stub confidence from 0.5 to 0.0 (below 0.6
threshold, preventing accidental orders) and add warn! log

- WebSocket stream bridges: replace permanent pending() stalls with
actual gRPC streaming subscriptions and exponential backoff reconnection
- Risk metrics: replace fake sharpe_ratio=1.5, sortino_ratio=2.0 with 0.0
(not-yet-computed) and wire circuit breaker status to real kill switch
- ML orders: use actual ensemble prediction direction and confidence
instead of hardcoded BUY at 0.65 confidence
- Fallback signal: return Err instead of fabricated Hold at 0.60 confidence
to prevent accidental trades when ML pipeline is disconnected

Add #![deny(clippy::unwrap_used, clippy::expect_used)] to lib.rs and main.rs.

- emergency_stop: delegates to TradingServiceKillSwitch.emergency_shutdown()
which activates the global AtomicKillSwitch; returns Status::unavailable
when kill_switch_system is None rather than silently succeeding
- validate_order: reads max_order_quantity from config repository (falls back
to 1_000_000); additionally calls RiskEngine.check_var_limit() for VaR
validation when symbol and price are provided
- get_va_r: uses RiskEngine.calculate_marginal_var() for real VaR with a
parametric fallback; per-symbol marginal VaRs computed individually
- get_risk_metrics: derives portfolio_var_1d from RiskEngine; scales to 5d
and 30d via sqrt-of-time rule; remaining fields (Sharpe, beta, alpha,
current_drawdown) keep placeholder values with explicit TODO comments

Replace hardcoded uptime (3600s) with real elapsed time tracked via
Instant::now() in MonitoringServiceImpl constructor. Surface live kill
switch state (active, emergency, unhealthy) as critical_issues strings
in GetSystemStatusResponse. Set sysinfo-dependent CPU/memory/disk/network
metrics to 0.0 with TODO comments pending sysinfo crate integration.

Replace the hardcoded [0.5, 0.6, 0.7, 0.8, 0.9] mock in
`extract_features_for_symbol` with a real attempt to retrieve
market ticks via `market_data_repository.get_latest_prices`.
Derives a 51-dim feature vector (price mean/std/CV, momentum,
volume mean, tick count) from live tick data, padding unused
dimensions with zeros. Falls back to a zero-filled 51-dim
vector with a WARN log on any failure or empty response, ensuring
the ensemble prediction path is never blocked by missing data.
Also replaces the silent `info!` in `get_fallback_trading_signal`
with a WARN-level message that makes the mock-signal boundary
clearly visible in production logs and adds a TODO pointing to
real DQN epoch-30 checkpoint inference.

- Replace hardcoded `total_count: 0` with `summaries.len() as u32` in list_backtests

- Import `warn` from tracing alongside existing debug/error/info imports

- allocation.rs: get_asset_volatilities now uses flat 0.20 (20% annual vol)
instead of index-scaled 0.15+i*0.05; get_covariance_matrix diagonal is
0.04 (0.20^2) instead of 0.0225; get_ml_predictions uses 0.0 (neutral)
instead of 0.05+i*0.02. All three emit tracing::warn so mock state is
visible in production logs.
- training.rs: train_all emits tracing::warn that it is using a placeholder
loop and directs callers to use model-specific trainers for production.

Replace the stub OCSP implementation with a fully functional RFC 6960
compliant revocation checker that:
- Builds OCSP requests using SHA-1 hashes of issuer name/key via the
ocsp crate's CertId and OneReq types with proper DER encoding
- Sends requests via HTTP POST with correct Content-Type headers
- Parses DER-encoded OCSP responses to extract response status
(successful/malformed/internal-error/try-later/unauthorized)
- Determines certificate status (Good/Revoked/Unknown) by locating
the serial number and scanning for ASN.1 context-specific tags
- Caches results in the existing LRU cache with TTL
- Increments Prometheus metrics for all failure paths
Add #![deny(clippy::unwrap_used, clippy::expect_used)] to api_gateway and
backtesting_service crate roots. The ml and common crates already had these
deny attributes.
Production code fixes:
- api_gateway: replace expect with unwrap_or for cache stats and LRU eviction
- api_gateway: add #[allow] on NonZeroU32 constants and Prometheus metrics
- backtesting_service: replace expect/unwrap with ok_or_else/? for OHLCV
bar bounds checks and chrono timestamp resampling
- backtesting_service: add #[allow] on Prometheus Lazy metric statics
Test code: cfg_attr(test, allow) at crate root for both crates.

Replace the TODO placeholder with proper CRL validation that checks:
- thisUpdate is not in the future (CRL not yet valid)
- nextUpdate is not in the past (CRL expired)
- CRL issuer matches the certificate issuer (prevents CRL substitution)
All checks use x509-parser's ASN1Time for accurate time comparison
and log warnings/errors via tracing for operational visibility.

Replace the TODO stub in validate_certificate_chain with full
cryptographic chain-of-trust verification using x509-parser's ring-backed
verify feature:
1. Issuer CN matching -- client cert issuer must equal CA subject CN
2. CA validity period -- reject expired or not-yet-valid CA certificates
3. CA Basic Constraints -- verify the signer actually has cA=true
4. Cryptographic signature -- verify client cert TBS data signature
against the CA's SubjectPublicKeyInfo (RSA/ECDSA/Ed25519 via ring)
Also enables the "verify" feature on x509-parser and extends the method
signature to accept ca_cert_pem for proper chain validation.

Replace 6 unwrap() calls with safe error handling in DQN IQN code:
- Production: 3 unwrap() on iqn_network/iqn_target_network replaced with
ok_or_else returning MLError::ModelError for clear diagnostics
- Tests: 2 result.unwrap() replaced with ?, 2 DQN::new().unwrap() replaced
with ? after changing test signatures to return anyhow::Result<()>

Introduces ml/src/types/ohlcv.rs as the single source of truth for
OHLCVBar (DateTime<Utc>, f64). Replaces 13 identical struct definitions
scattered across features/, regime/, real_data_loader, and evaluation/.
The f32 backtesting variant in evaluation/metrics.rs is renamed to
OHLCVBarF32 to distinguish it from the canonical type. The regime_adx.rs
i64-timestamp variant was safely migrated since its timestamp field was
never accessed. The orchestrator's Bar alias is replaced with OHLCVBar.
39 files changed, -151 net lines removed.

CRITICAL BLOCKER FIX: Tests were hanging for 60+ seconds due to invalid
Redis timeout URL parameters that are silently ignored by redis v0.27.6.
Root Cause:
- redis crate v0.27.6 does NOT support connection_timeout or response_timeout
as URL parameters
- When Redis unavailable, code blocks waiting for OS-level TCP timeout (60s+)
Solution:
- Wrap async Redis operations with tokio::time::timeout()
- Test timeouts: 2s connection, 1s operations (PING/FLUSHDB)
- Production timeout: 5s connection
Files Modified:
- services/api_gateway/tests/common/mod.rs (lines 119-211)
- Fixed wait_for_redis() with tokio timeout wrappers
- Fixed cleanup_redis() with tokio timeout wrappers
- Removed broken add_redis_timeouts() function
- services/api_gateway/src/auth/jwt/revocation.rs (lines 285-316)
- Fixed JwtRevocationService::new() with tokio timeout wrapper
Closes: JWT authentication test hang blocker
Impact: Tests now fail fast (2-5s) instead of hanging for 60+ seconds
