8afe53619f feat(trading_service): wire monitoring to real uptime and kill switch status 
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.

c5758c30ef feat(trading_service): wire feature extraction to real market data pipeline 
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.

e5fd216b04 fix(trading_service, ml): replace silently-mock allocation data with logged defaults 
- 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.

80099a6799 feat(security): implement OCSP revocation checking 
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

15c094c7ee safety: add clippy deny(unwrap_used, expect_used) to api_gateway, backtesting_service 
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.

3fe6f1cb90 security(api-gateway): add CRL validity period and issuer validation 
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.

4c23f8c50c security(api-gateway): implement X.509 signature verification for mTLS 
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.

533459570b refactor(ml): consolidate 13 duplicate OHLCVBar structs into canonical types module 
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.

d8b97c4616 fix(api_gateway): Add missing Context import for JWT timeout handling 
- Import anyhow::Context trait in tests/common/mod.rs
- Required for .context() method calls in cleanup_redis()
- Completes JWT auth timeout fix (test + production code)

Fixes services/api_gateway/tests/common/mod.rs:198
Fixes services/api_gateway/tests/common/mod.rs:207

Test Results: 28/30 auth_edge_cases tests pass in 1.12s (was 60s+ timeout)
- 2 failures due to pre-existing revocation cache bug (separate issue)
- Cache stores 'not revoked' results for 60s, blocking revocation detection

675695986e fix(api_gateway): Fix JWT auth test hang with proper Redis timeouts 
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

845e77a8b0 fix(ci): Fix GitLab CI YAML syntax and PPOConfig compilation errors 
Two critical fixes for successful pipeline execution:

1. GitLab CI YAML Syntax Fix (.gitlab-ci.yml:84-86)
   - Wrapped echo commands containing colons in single quotes
   - Root cause: YAML parser interprets `"text: value"` as key-value pairs
   - Solution: Single quotes force literal string interpretation
   - Impact: Enables Docker build pipeline execution

2. Trading Service Compilation Fix (trading_service/src/services/enhanced_ml.rs:1328-1348)
   - Added missing early stopping fields to PPOConfig initialization
   - Fields: early_stopping_enabled, early_stopping_patience, early_stopping_min_delta, early_stopping_min_epochs
   - Values: Disabled by default for paper trading (early_stopping_enabled: false)
   - Impact: Resolves pre-push hook compilation error

Technical Details:
- YAML Issue: Colons followed by spaces trigger mapping syntax parsing
- Single quotes preserve shell variable expansion while forcing literal YAML strings
- Early stopping config matches PPOConfig struct updates from Wave D
- Default values: patience=5, min_delta=0.001, min_epochs=10

Validated:
- ✅ YAML syntax validated with PyYAML
- ✅ trading_service compilation successful (cargo check)
- ✅ Ready for GitLab CI/CD pipeline execution
