7b0bcc20b6 🎉 SUCCESS: All test packages compile without errors!
## Summary
Deployed 4 parallel agents to systematically resolve all remaining compilation
errors in test infrastructure and ml-data crate. All targeted packages now
compile successfully.

## Agent 1: Fix e2e_test_runner (6 errors → 0 errors)

### Changes to tests/e2e/Cargo.toml:
- Added `clap = { version = "4.0", features = ["derive"] }`

### Changes to tests/e2e/src/bin/e2e_test_runner.rs:
- Changed imports from `foxhunt_e2e::` to `e2e_tests::` (matching actual library name)
- Added inline stub implementations for Corrode integration:
  - `CorrodeConfig`, `CorrodeTestRunner`
  - `TestExecutionRequest`, `TestExecutionResult`
- Fixed tracing setup to use `tracing_subscriber` directly
- Fixed string matching: `match format` → `match format.as_str()`
- Updated all package references: `--package foxhunt-e2e` → `--package e2e_tests`

## Agent 2: Fix service_orchestrator (10 errors → 0 errors)

### Changes to tests/e2e/Cargo.toml:
- Added `reqwest = { version = "0.12", features = ["rustls-tls", "json"] }`

### Changes to tests/e2e/src/bin/service_orchestrator.rs:
- Changed imports from `foxhunt_e2e::` to `e2e_tests::`
- Fixed sqlx API: `connect_timeout()` → `acquire_timeout()` (sqlx 0.8)
- Fixed borrow checker: `for service_type in` → `for service_type in &`
- Fixed clap lifetime issues in `restart_services()`

### Changes to tests/e2e/src/services.rs:
- Added `ServiceType` enum with variants: TradingService, BacktestingService, MLTrainingService, Database
- Added orchestrator-compatible `ServiceConfig` struct
- Renamed original config to `LegacyServiceConfig` for backward compatibility
- Updated `ServiceManager::new()` to return `Self` directly (not `Result`)
- Added `ServiceManager::start_service()` method for new `ServiceConfig`

### Changes to tests/e2e/src/utils.rs:
- Added `PerformanceProfiler` struct with methods: `new()`, `checkpoint()`, `print_summary()`
- Added `TestUtils` struct with static methods: `setup_test_logging()`, `wait_for_condition()`, `check_service_health()`

### Changes to tests/e2e/src/framework.rs:
- Updated `ServiceManager::new()` call to not use `.context()` (returns `Self` now)

## Agent 3: Fix ml-data syntax error (1 error → 0 errors)

### Changes to ml-data/src/training.rs:
- **Line 123**: Added missing comma after `format!()` call in match arm
  ```rust
  // Before:
  Some(desc) => format!("'{}'", desc.replace("'", "''"))  // Missing comma

  // After:
  Some(desc) => format!("'{}'", desc.replace("'", "''")),  // Added comma
  ```

## Agent 4: Dependency Audit (Completed)

Provided comprehensive audit report identifying all missing dependencies,
which informed fixes by Agents 1 and 2.
