🏗️ Database Schema Evolution

BEFORE: String-based (Not Type-Safe)

CREATE TABLE ensemble_predictions (
    id UUID PRIMARY KEY,
    ensemble_action TEXT,  -- ❌ "BUY", "SELL", "HOLD" (string)
    -- ...
);

-- String validation at runtime
SELECT * FROM ensemble_predictions
WHERE ensemble_action = 'BUY';  -- ❌ Typo-prone ("buy" vs "BUY")

AFTER: Enum-based (Type-Safe)

-- Migration: Add 'hold' to order_side enum
ALTER TYPE order_side ADD VALUE 'hold';

CREATE TABLE ensemble_predictions (
    id UUID PRIMARY KEY,
    ensemble_action order_side,  -- ✅ Enum: {buy, sell, hold}
    -- ...
);

-- Type-safe enum validation at database level
SELECT * FROM ensemble_predictions
WHERE ensemble_action = 'hold';  -- ✅ Database validates enum value

🎯 Rollout Strategy

Phased Implementation (7 Phases)

Phase 1: Core Types (1h)
├─ Add Hold to common::types::Side
├─ Delete common::trading::OrderSide
├─ Add helper methods
└─ Database migration

Phase 2: ML Models (2h)
├─ ml/src/ensemble/decision.rs
├─ ml/src/dqn/agent.rs
├─ ml/src/ppo/agent.rs
└─ Update ML tests (15+ files)

Phase 3: Trading Services (2h)
├─ paper_trading_executor.rs
├─ ensemble_coordinator.rs
└─ strategy_engine.rs

Phase 4: gRPC Protos (1h)
├─ tli/proto/trading.proto
├─ services/trading_service/proto/trading.proto
└─ Regenerate proto code

Phase 5: Database (30min)
├─ Migration: ADD VALUE 'hold'
└─ Update SQLX offline data

Phase 6: Tests (2h)
├─ Delete duplicate enums (10+ files)
├─ Update test assertions (20+ files)
└─ Add Hold action tests

Phase 7: Validation (1h)
├─ Full test suite
├─ ML prediction generation
├─ gRPC API tests
└─ Database persistence checks
