Remove dependencies declared in 5 service Cargo.toml files that no
source code in those services references (verified by grepping for
use statements). Reduces dep-graph fan-out and unnecessary recompiles.
services/api/Cargo.toml −16 deps (async-trait, bytes,
const-oid, hdrhistogram,
hex, http-body, hyper,
hyper-util, num-traits,
rust_decimal, tokio-stream,
tower-layer, tower-service,
tracing-subscriber,
trading_engine, zeroize.
+ json feature added to
reqwest since trading_engine
was enabling it transitively)
services/trading_service/Cargo.toml −11 deps
services/backtesting_service/Cargo.toml −17 deps
services/trading_agent_service/Cargo.toml −6 deps
services/ml_training_service/Cargo.toml −4 deps
False positives kept (cargo-machete misses these because they're only
referenced in tonic-generated proto code, not in hand-written src):
- prost (`::prost::Message` derive in build.rs-generated code)
- tonic-prost (`tonic_prost::ProstCodec::default()` in generated tonic
clients/servers)
cargo check --workspace passes.

migrations:
- 001_trading_events.sql, 003_audit_system.sql: the hard-coded
node_id literals (`trading-node-01`, `audit-node-01`,
`ml-node-01`, `system-node-01`, `change-tracker-01`) are
overridden per-deployment by later migrations rather than read
from the environment. Describe that in the inline comment.
- 004_compliance_views.sql: `generate_compliance_report` is a log
stub — actual report generation is performed by the compliance
service. Say so explicitly.
services:
- ml_training_service/tests/orchestrator_225_features_test.rs: the
empty `#[ignore]`d placeholder for the 225-feature orchestrator
loader has been removed; it held no assertions and only tracked
a TODO (feedback_no_stubs.md).
- trading_agent_service/src/service.rs: portfolio volatility uses
the diagonal-only approximation because cross-asset return
correlations are not maintained in this service. Document that.
- trading_service/src/services/risk.rs: `get_risk_metrics` uses
`calculate_marginal_var` + asset-class fallback; describe why
`calculate_comprehensive_var` is not wired at this boundary.
- trading_service/tests/auth_comprehensive.rs: delete the entire
commented-out legacy BackupCodeValidator test block — the old
`generate_backup_codes` / `store_backup_code` /
`verify_backup_code` surface no longer exists, and MFA
integration tests already cover the new API.
testing:
- harness/grpc_clients.rs: no BacktestingServiceClient proto
exists; reword the stale TODO import line.
- chaos/*: reword the family of "TODO: Implement ..." stubs as
"Currently a no-op / synthetic result" descriptions so readers
know exactly how much of the chaos framework is live.
- compliance_automation_tests.rs: delete the file; it was a giant
/* ... */ block referencing a nonexistent compliance module
and was not wired into any Cargo target.
- framework.rs: describe why `setup()` uses `println!` instead of
`tracing_subscriber` (tracing_subscriber is not a dep of this
integration crate).

Rename 7 service binaries from snake_case to kebab-case to match
K8s deployment names. Update Cargo.toml package/bin names, K8s
manifest S3 paths and commands, and cross-crate dependency keys.
- api_gateway → api-gateway
- trading_service → trading-service
- broker_gateway_service → broker-gateway
- ml_training_service → ml-training-service
- backtesting_service → backtesting-service
- trading_agent_service → trading-agent-service
- data_acquisition_service → data-acquisition-service
broker-gateway gets an explicit [lib] name = "broker_gateway_service"
since its new package name maps to broker_gateway (not the original
broker_gateway_service used in source code). All other services map
correctly with Rust's automatic hyphen-to-underscore conversion.

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)

Remove unnecessary async from init_observability -- body was fully sync.
Change otlp_endpoint from &str to Option<&str> -- when None, OTLP layer
is skipped (fmt-only mode). Update all 8 service callers.

Create 3 missing service READMEs (api_gateway, data_acquisition_service,
trading_agent_service). Create bin/fxt/README.md. Create
testing/service-integration/README.md. Update existing service and testing
READMEs to standard template. Delete 4 subdirectory READMEs from
testing/integration/ and testing/e2e/.

Remove stale test reports, quick-start guides, benchmark analyses,
profiling reports, and tool artifacts from across the workspace.
Keeps only root README.md per crate/service.

Replace the liquidity heuristic in score_symbols with a real
GetEnsembleVote gRPC call to trading-service. Each symbol gets a
concurrent RPC; on failure the original liquidity*0.9+0.1 heuristic
is used as fallback. The ML client is lazily initialized via OnceCell
and the service URL is configurable via ML_SERVICE_URL env var.

- Delete push_metrics.rs (Pushgateway client, zero consumers)
- Delete 5 legacy test/bench files for MLFeatureExtractor + SimpleDQNAdapter
- Remove MLFeatureExtractor from trading_agent_service, use direct bar scoring
- Remove with_feature_extractor() method and Arc<MLFeatureExtractor> parameter
- Remove bench target from common/Cargo.toml

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.

Move 17 library crates into crates/, CLI binary into bin/fxt,
consolidate 10 test crates into testing/, split config crate
from deployment config files.

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.

Coordinator (ml/src/integration/coordinator.rs):
- Delete 9 fake heuristic methods (500+ lines) that pretended to be
real DQN/TFT/TGGN/LNN/Mamba predictions using sin()/tanh() math
- Make generate_model_specific_prediction() return Err instead of
fake predictions — prevents trading on fabricated signals
- Make ensemble fault-tolerant: skip failed models instead of
failing entire ensemble (execute_parallel/execute_sequential)
- Remove double-fallback in execute_single_model error path
Enhanced ML (trading_service):
- get_model_performance(): compute accuracy from real
inference_count/error_count instead of returning all zeros
- get_feature_importance(): return Status::unavailable instead of
hardcoded fake values — honest about missing SHAP implementation
Autonomous scaling (trading_agent_service):
- diversification_score: compute real HHI from instrument volume
distribution instead of hardcoded 0.8
- ml_confidence: keep liquidity heuristic but remove warn!() spam
Position limiter (risk):
- Remove redundant portfolio_id field from CachedPosition — the
DashMap key already provides account-based isolation
- Remove misleading "stub" comment — was not a stub

All 6 service Dockerfiles were missing newly-added workspace crates
(web-gateway, ctrader-openapi, foxhunt-deploy, broker_gateway_service),
causing cargo workspace resolution failures during Docker builds.
Changes across all Dockerfiles:
- Add COPY directives for web-gateway, ctrader-openapi, foxhunt-deploy,
broker_gateway_service (new workspace members since Dockerfiles written)
- Add SQLX_OFFLINE=true env and .sqlx cache copy where missing
- Add perl and make system deps (needed for OpenSSL build from source)
- Remove COPY migrations (dir excluded by .dockerignore, not needed)
- Expand broker_gateway_service from 3-crate to full workspace copy
Validated: docker build --check passes all 6, cargo check -p passes all 6.

Add optional correlation matrix parameter to mean-variance optimization.
When provided, builds full covariance matrix (Sigma[i][j] = corr[i][j] *
vol_i * vol_j) instead of diagonal-only. Existing API unchanged — callers
pass None by default. New allocate_with_correlations() public method for
correlated optimization. Five new tests: identity-matches-diagonal,
correlated-differs-from-diagonal, invalid dimensions, non-square matrix,
and non-MeanVariance delegation.

Replaces hardcoded zeros in AssetAllocation with real position data
queried from agent_orders. Adds fetch_current_positions() helper that
derives net quantity per symbol (buy - sell) and reuses it in both
allocate_portfolio and rebalance_portfolio to eliminate SQL duplication.

Replace 7 hardcoded 0.0 values with real calculations:
- target_quantity from last close price
- portfolio_volatility from log return stddev * sqrt(252)
- portfolio_sharpe from weighted returns / portfolio vol
- var_95 parametric VaR
- max_drawdown_estimate from vol approximation
- rebalance_delta as target - current (0 until positions available)
- per-asset volatility from price bars (was hardcoded 0.15)

Replace last 2 stub gRPC handlers with real implementations:
- GenerateOrders: loads allocation, generates orders via OrderGenerator with
ML signal context, contract price estimation, and dynamic stop-loss
- SubmitAgentOrders: validates orders, supports dry_run mode, persists to
agent_orders table with full metadata
Trading agent service: 15/15 endpoints now have real implementations.

Replace 4 stub gRPC handlers with real implementations:
- GetAllocation: re-computes allocation from latest asset selection via PortfolioAllocator
- RebalancePortfolio: compares target vs current positions, generates drift-based actions
- GetAgentPerformance: queries agent_orders for P&L, win rate, Sharpe, max drawdown
- StreamAgentActivity: sends 5-second heartbeat events until client disconnects
Trading agent service: 14/15 endpoints now have real implementations.

Replace 2 stub gRPC handlers with real implementations:
- SelectAssets: scores instruments via MLFeatureExtractor, ranks with
AssetSelector (TopN/Threshold/Quantile modes), persists to DB
- GetSelectedAssets: loads latest selection from asset_selections table
Add helper methods: score_instrument, store/load_asset_selection

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.
