kube-rs Client::try_default() uses rustls for in-cluster TLS but no
CryptoProvider was installed, causing a panic on first pod list call.

- StreamSystemStatus now queries real Prometheus data (was all zeros)
- StreamAlerts returns honest unimplemented (was sending empty events)
- Training epoch shows "N" not "N/0" (max_epochs not in proto)
- GPU power shows "300W" not "300W / 0W" when limit unavailable
- Services cockpit shows error reason when service is DOWN
- System status polling detects staleness after 3 consecutive failures
- Training cockpit header shows active K8s job count

config_service.proto (package foxhunt.config, 4 RPCs) was a subset of
config.proto (package config, 12 RPCs). Migrated api_gateway to implement
ConfigService from config.proto directly. Removed dead config_service()
method from fxt client.

Add kube 3.0 + k8s-openapi 0.27 dependencies and create pods_handler.rs
that queries the Kubernetes API for pod status. Replace the UNIMPLEMENTED
stub in monitoring_handler.rs with a real streaming implementation that
polls pods every N seconds and maps them to PodInfo proto messages.

Replace 3 stub RPCs with real implementations:
- get_system_status: fan-out gRPC health checks to all backends, reports SystemStatus
- get_health_check: fan-out checks with response time measurement, returns HealthCheck entries
- get_metrics: queries Prometheus for requested metric names
MonitoringServiceHandler now accepts backend URLs via with_backends() builder.

- Read new env vars: BROKER_GATEWAY_SERVICE_URL, DATA_ACQUISITION_SERVICE_URL,
ML_SERVICE_URL, TRADING_AGENT_SERVICE_URL
- Create lazy channels: trading channel shared by trading/risk/config proxies,
separate channels for ML, broker, data_acq, trading_agent
- Register 7 new services on router with auth interceptor
- Update reflection service with all 6 new proto descriptors
- Add broker/data_acq/trading_agent to health check backend list

Port Prometheus scraping and training metrics RPCs directly into
api_gateway, eliminating the monitoring-service backend proxy.
MonitoringServiceProxy replaced with MonitoringServiceHandler that
queries Prometheus directly for training metrics, GPU stats, and
active job counts.
Changes:
- monitoring_proxy.rs -> monitoring_handler.rs with embedded PrometheusClient
- Remove MonitoringBackendConfig and setup_monitoring_proxy from server.rs
- main.rs reads PROMETHEUS_URL + MONITORING_STREAM_INTERVAL instead of
MONITORING_SERVICE_URL
- Remove monitoring-service from backend health check list
- Monitoring is always available (no graceful degradation needed)
- Fix fxt build.rs compile_protos type mismatch
- All 9 ported unit tests + 0 clippy warnings

Delete per-service proto/ directories. All 7 services now compile
from the single canonical proto/ at workspace root.
- trading_service: 5 protos + ml_training client -> ../../proto/
- ml_training_service: ml_training server + fxt_trading client -> ../../proto/
- broker_gateway_service: broker_gateway -> ../../proto/
- trading_agent_service: trading_agent + ml client -> ../../proto/
- data_acquisition_service: data_acquisition -> ../../proto/
- api_gateway: 8 proto compilations -> ../../proto/
- monitoring_service: keeps local proto (3 training RPCs only, deleted in Task 5)
Added proto/fxt_trading.proto (fat-client proto, package foxhunt.tli)
separate from proto/trading.proto (backend, package trading) since the
API gateway needs both for protocol translation.
Added unimplemented stubs for merged monitoring.proto RPCs:
- trading_service: 3 training RPCs (served by monitoring_service)
- api_gateway monitoring_proxy: 13 system health RPCs (Task 4)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add file_descriptor_set_path for all proto compilations (enables gRPC reflection)
- Add BackendHealthState and ServiceHealthEntry for structured health tracking
- Export health types from grpc module
- Fix web-gateway network policy port

Swap the stale trading_service monitoring proto (10 RPCs, never
implemented) for the real monitoring_service proto (2 RPCs:
GetLiveTrainingMetrics, StreamTrainingMetrics). Add a dedicated
MonitoringServiceProxy that forwards directly to monitoring-service
on port 50057, so `fxt watch` works end-to-end through the gateway.
- build.rs: compile monitoring_service/proto/monitoring.proto with server+client
- MonitoringServiceProxy: new zero-copy proxy (unary + streaming)
- TradingServiceProxy: remove monitoring_client, stub 6 stale methods
- main.rs: MONITORING_SERVICE_URL env, optional proxy with graceful degradation
- Network policies: api-gateway↔monitoring-service egress/ingress on 50057

Add tracing::instrument(skip_all) to gRPC handlers across all services
for distributed trace spans via OTLP. Pairs with Prometheus scrape
annotations from previous commit.

Replace direct tracing_subscriber::fmt::init() calls with the unified
common::observability::init_observability() in api_gateway, web-gateway,
data_acquisition_service, broker_gateway_service, and trading_agent_service.
All 8 services now emit JSON logs + OTLP traces to Tempo.

Extend ml_training_service to dispatch GPU training jobs as K8s batch/v1
Jobs, collect results via a Rust sidecar uploader, and support model
promotion with operator approval via fxt CLI.
- K8s dispatcher creates Jobs on gpu-training pool with native sidecar
- training_uploader crate: watches DONE/FAILED marker, uploads to S3,
reports completion via ReportJobCompletion gRPC
- PromotionManager compares metrics, queues better models for approval
- 4 new proto RPCs: ReportJobCompletion, ListPendingPromotions,
ApprovePromotion, RejectPromotion
- fxt commands: train start, model list/approve/reject
- Training binaries write DONE/FAILED markers + metrics.json
- Dockerfile, K8s job template, and CI pipeline updated
- StartTraining gracefully falls back to in-process when outside K8s
- 27 new tests (16 service + 11 promotion), 141 total service tests pass

Strip all 413 #[allow(dead_code)] annotations from 139 files and remove
the actual dead code they were suppressing: unused struct fields (and their
constructor sites), unused methods/functions, and entire dead structs.
Key removals:
- trading_engine compliance: ~50 dead structs/fields across audit, reporting, SOX modules
- trading_service: dead execution engine fields, broker routing, paper trading methods
- ml_training_service: dead TLS validation (~340 lines), GPU state, monitoring fields
- backtesting_service: dead model cache, TLS validation, TradeSignal fields
- risk: dead VaR engine fields, safety coordinator fields, position tracker fields
- adaptive-strategy: dead ensemble methods, regime detection, sizing functions
147 files changed, -4264 net lines. Workspace compiles with 0 errors.

Tasks 8-14 production hardening batch:
- Populate Order/Position/Execution proto messages from JSON payload in event
stream converters instead of returning None (Task 9)
- Compute max_drawdown from cumulative PnL samples in A/B testing pipeline
instead of hardcoded 0.0 (Task 11)
- Document feature pipeline integration blockers with detailed roadmap
comments in state.rs and trading.rs (Task 8)
- Document realized PnL gap: TradingPosition lacks the field, repository
has async method incompatible with Iterator::map (Task 10)
- Document ML order quantity gap in api_gateway proxy: MlOrderResponse
proto lacks quantity field (Task 12)
- Document per-symbol weight tracking roadmap in ensemble_coordinator (Task 13)
- Document OHLCV bar pipeline upgrade roadmap in state.rs (Task 14)

Move identical TLS type definitions from 4 service crates into
common/src/tls.rs, eliminating ~435 lines of duplicated code.
Each service retains its own TlsConfig struct and validation logic
(async vs sync, delegated vs monolithic) while sharing the type
definitions. Services re-export the types for backward compatibility.

- api_gateway/revocation.rs: 7 Prometheus .unwrap()→abort pattern
- ml_training/simple_metrics.rs: remove #![allow(clippy::unwrap_used)],

- api_gateway/main.rs: 18 expect→? or match+error! (gateway crash=outage)
- broker_gateway/metrics.rs: 24 expect→unwrap_or_else+abort (startup-only)
- ml_training/training_metrics.rs: 32 unwrap→unwrap_metric helper+abort
All Prometheus metric registrations now use explicit error handling
instead of bare .unwrap()/.expect(). Production panic surface reduced
by ~75%.

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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.

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
- Add .t() transpose to all weight matrix multiplications
- Add .contiguous() after transpose to fix non-contiguous errors
- Fix causal mask using additive masking instead of where_cond
- Fix mask dtype compatibility (F32 instead of U8)
All 8 quantized_attention tests now passing.
**Problem**:
- api_gateway binary and real_backend_integration_test had compilation errors
- Missing observability module caused binary to fail compilation
- Incorrect proto imports and field access in integration tests
**Changes**:
1. services/api_gateway/src/main.rs:
- Removed call to common::observability::init_observability (module commented out in common)
- Replaced with simple tracing_subscriber::fmt::init()
- Removed unused imports (layer::SubscriberExt, util::SubscriberInitExt)
2. services/api_gateway/tests/real_backend_integration_test.rs:
- Fixed proto imports: use tli::proto::health::{HealthClient, HealthCheckRequest}
- Replaced TradingServiceClient with HealthClient (standard gRPC health check)
- Replaced BacktestingServiceClient with HealthClient
- Fixed field access: health.status -> health.healthy for ML service
- Fixed field access: health.status string -> health.status i32 (ServingStatus enum)
- Updated all 8 test functions to use correct proto types
- Pre-commit hook automatically changed .health_check() to .check() (correct method name)
**Tests Fixed**:
- api_gateway binary compilation (1 error fixed)
- real_backend_integration_test compilation (7 errors fixed)
**Impact**:
- 2 of 6 service test failures resolved
- api_gateway binary now compiles and runs
- Integration tests now use correct proto definitions
