-- Returns: Empty result set (no data yet, function operational)

✅ Function callable

Result: ✅ PASS - Migration validation successful.

---

4. Service Build Validation

4.1 Build Attempt: Trading Service

Command:

cargo build --release -p trading_service

Result: ❌ FAIL - Compilation error

Error Details:

error[E0046]: not all trait items implemented, missing: `get_regime_state`, `get_regime_transitions`
  --> services/trading_service/src/services/trading.rs:42:1
   |
42 | impl trading_service_server::TradingService for TradingServiceImpl {
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ missing `get_regime_state`, `get_regime_transitions` in implementation

4.2 Root Cause Analysis

Investigation:

1. Checked trading.rs file structure (1336 lines)
2. Found regime methods at lines 1230-1335:
   • async fn get_regime_state() at line 1230
   • async fn get_regime_transitions() at line 1278
3. Discovered trait implementation block ends at line 934
4. Regime methods are OUTSIDE the trait impl block (in separate impl TradingServiceImpl block starting at line 936)

Root Cause: Regime methods defined outside #[tonic::async_trait] impl trading_service_server::TradingService block.

File Structure:

// Line 42
impl trading_service_server::TradingService for TradingServiceImpl {
    async fn submit_order(...) { ... }
    async fn cancel_order(...) { ... }
    // ... other trait methods ...
    async fn get_portfolio_summary(...) { ... }
    // Line 934: TRAIT IMPL BLOCK ENDS HERE
}

// Line 936: NEW IMPL BLOCK (NOT PART OF TRAIT)
impl TradingServiceImpl {
    async fn validate_order_risk(...) { ... }
    async fn publish_order_event(...) { ... }
    async fn calculate_model_performance_metrics(...) { ... }

    // Line 1230: Regime methods (OUTSIDE TRAIT IMPL!)
    async fn get_regime_state(...) { ... }      // ❌ Should be in trait impl
    async fn get_regime_transitions(...) { ... } // ❌ Should be in trait impl
}
// Line 1336: End of file

Impact: Cannot build trading_service binary, blocking all deployment activities.

4.3 Build Attempt: API Gateway

Status: ⏸️ Not attempted (blocked by SQLX_OFFLINE cache issues in common crate)

Error:

error: `SQLX_OFFLINE=true` but there is no cached data for this query
error: could not compile `common` (lib) due to 6 previous errors

Note: API Gateway depends on common crate which has SQLX queries requiring cache updates.

4.4 Build Attempt: Backtesting Service

Status: ⏸️ Not attempted (blocked by same SQLX_OFFLINE issues)

Result: ❌ FAIL - Cannot build any release binaries until compilation errors are fixed.

6. Rollback Procedure Validation

6.1 Rollback Test Execution

Objective: Validate Wave D migration can be rolled back safely in <2 minutes.

Test Database: foxhunt_staging (SAFE - not production)

Rollback Script: /tmp/rollback_wave_d.sql

-- Rollback Wave D regime tracking tables
DROP TABLE IF EXISTS adaptive_strategy_metrics CASCADE;
DROP TABLE IF EXISTS regime_transitions CASCADE;
DROP TABLE IF EXISTS regime_states CASCADE;

-- Drop Wave D functions
DROP FUNCTION IF EXISTS get_latest_regime(TEXT);
DROP FUNCTION IF EXISTS get_regime_transition_matrix(TEXT, INTEGER);
DROP FUNCTION IF EXISTS get_regime_performance(TEXT, INTEGER);

Execution:

$ psql foxhunt_staging -f /tmp/rollback_wave_d.sql
DROP TABLE
DROP TABLE
DROP TABLE
DROP FUNCTION
DROP FUNCTION
DROP FUNCTION

Execution Time: ~0.3 seconds (target: <2 minutes) ✅

Verification (Post-Rollback):

$ psql foxhunt_staging -c "\dt regime*"
Did not find any relation named "regime*".

$ psql foxhunt_staging -c "\dt adaptive*"
Did not find any relation named "adaptive*".

$ psql foxhunt_staging -c "SELECT proname FROM pg_proc WHERE proname LIKE '%regime%';"
(0 rows)

Result: ✅ All Wave D objects removed successfully.

6.2 Re-Apply Migration (Forward Test)

Objective: Validate migration can be re-applied after rollback.

Command:

$ psql foxhunt_staging -f /home/jgrusewski/Work/foxhunt/migrations/045_wave_d_regime_tracking.sql

Result: ✅ Migration re-applied successfully (same output as initial application)

Verification (Post-Re-Apply):

$ psql foxhunt_staging -c "\dt regime*"
regime_states
regime_transitions

$ psql foxhunt_staging -c "\dt adaptive*"
adaptive_strategy_metrics

$ psql foxhunt_staging -c "SELECT proname FROM pg_proc WHERE proname LIKE '%regime%';"
get_latest_regime
get_regime_transition_matrix
get_regime_performance

Result: ✅ All 3 tables and 3 functions restored.

6.3 Rollback Procedure Validation Summary

Test	Target	Actual	Status
Rollback Execution Time	<2 minutes	~0.3 seconds	✅ PASS (600x under target)
Tables Dropped	3	3	✅ PASS
Functions Dropped	3	3	✅ PASS
Data Loss Check	0 rows	0 rows	✅ PASS (empty tables)
Re-Apply Success	Yes	Yes	✅ PASS
Re-Apply Idempotency	Yes	Yes	✅ PASS

Overall Rollback Validation: ✅ PASS - Rollback procedure is safe, fast, and reliable.

7. Critical Blockers

7.1 Blocker #1: Trading Service Compilation Error (CRITICAL)

Issue: Regime methods (get_regime_state, get_regime_transitions) are implemented OUTSIDE the gRPC trait implementation block.

Location: /home/jgrusewski/Work/foxhunt/services/trading_service/src/services/trading.rs

Lines:

• Trait impl ends: Line 934
• Regime methods start: Line 1230 (106 lines too late)

Root Cause: Code structure error - methods defined in separate impl TradingServiceImpl block instead of impl trading_service_server::TradingService block.

Fix Required:

1. Move lines 1230-1335 (regime methods) UP to line 920 (before trait impl block closes)
2. Ensure methods remain in #[tonic::async_trait] impl trading_service_server::TradingService block
3. Remove duplicate impl block header if needed

Estimated Fix Time: 5-10 minutes (code move + compilation test)

Impact:

• ❌ Cannot build trading_service binary
• ❌ Cannot deploy to staging or production
• ❌ Cannot execute integration tests (E9)
• ❌ Cannot run paper trading smoke test (E10)
• ❌ Blocks all remaining Phase 5 agents (E20)

Severity: 🔴 P0 CRITICAL - Deployment blocker

Workaround: None (must be fixed)

7.2 Blocker #2: SQLX Cache Out of Sync (HIGH)

Issue: common crate and api_gateway have SQLX queries without cached metadata, blocking builds when SQLX_OFFLINE=true.

Error:

error: `SQLX_OFFLINE=true` but there is no cached data for this query, run `cargo sqlx prepare`

Affected Crates:

• common (6 queries)
• api_gateway (depends on common)

Root Cause: Wave D regime queries in trading_service not yet in SQLX cache.

Fix Required:

cd /home/jgrusewski/Work/foxhunt/services/trading_service
export DATABASE_URL="postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt"
cargo sqlx prepare
git add .sqlx/*.json

Estimated Fix Time: 2 minutes

Impact:

• ❌ Cannot build api_gateway binary (depends on common)
• ❌ Cannot build backtesting_service binary (depends on common)
• ⚠️ Only affects SQLX_OFFLINE builds (CI/CD pipelines)

Severity: 🟡 P1 HIGH - Affects CI/CD, not local dev (can build with SQLX_OFFLINE=false)

Workaround: Build with SQLX_OFFLINE=false (requires database connection)

Production Readiness: NO-GO until blockers fixed (estimated 12 minutes)

Next Steps:

1. Fix trading_service compilation error (move lines 1230-1335 before line 934)
2. Update SQLX cache (cargo sqlx prepare)
3. Re-run deployment dry-run (Agent E20)
4. Execute 24-hour staging validation
5. Production GO/NO-GO decision (Day 2)

Estimated Time to Production: 3 days (after blockers fixed)

Deployment Recommendation: DO NOT PROCEED with production deployment until:

1. Both P0 and P1 blockers are resolved
2. Release binaries build successfully
3. Integration tests passing on staging
4. 24-hour staging validation complete (0 incidents)
5. Stakeholder approval obtained

This dry-run report provides a comprehensive assessment of production readiness and identifies critical blockers preventing deployment. The rollback procedure has been validated and is operational, providing a safety net for production deployment once blockers are resolved.
