---

Pre-Deployment Actions (15 minutes total)

1. Fix Database Migration (5 minutes) ⚠️

The ensemble tables migration partially failed due to TimescaleDB hypertable requiring a composite PRIMARY KEY. Here's the fix:

# Drop incomplete table
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "DROP TABLE IF EXISTS ensemble_predictions CASCADE;"

# Create fixed version (composite PRIMARY KEY for hypertable)
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt << 'SQL'
CREATE TABLE ensemble_predictions (
    id UUID DEFAULT gen_random_uuid(),
    timestamp TIMESTAMPTZ NOT NULL DEFAULT NOW(),
    symbol VARCHAR(20) NOT NULL,
    ensemble_action VARCHAR(10) NOT NULL CHECK (ensemble_action IN ('BUY', 'SELL', 'HOLD')),
    ensemble_signal DOUBLE PRECISION NOT NULL CHECK (ensemble_signal >= -1.0 AND ensemble_signal <= 1.0),
    ensemble_confidence DOUBLE PRECISION NOT NULL CHECK (ensemble_confidence >= 0.0 AND ensemble_confidence <= 1.0),
    disagreement_rate DOUBLE PRECISION NOT NULL CHECK (disagreement_rate >= 0.0 AND disagreement_rate <= 1.0),
    dqn_signal DOUBLE PRECISION,
    dqn_confidence DOUBLE PRECISION,
    dqn_weight DOUBLE PRECISION,
    dqn_vote VARCHAR(10),
    ppo_signal DOUBLE PRECISION,
    ppo_confidence DOUBLE PRECISION,
    ppo_weight DOUBLE PRECISION,
    ppo_vote VARCHAR(10),
    mamba2_signal DOUBLE PRECISION,
    mamba2_confidence DOUBLE PRECISION,
    mamba2_weight DOUBLE PRECISION,
    mamba2_vote VARCHAR(10),
    tft_signal DOUBLE PRECISION,
    tft_confidence DOUBLE PRECISION,
    tft_weight DOUBLE PRECISION,
    tft_vote VARCHAR(10),
    order_id UUID,
    executed_price BIGINT,
    position_size BIGINT,
    pnl BIGINT,
    commission BIGINT DEFAULT 0,
    slippage_bps INTEGER,
    ab_test_id UUID,
    ab_group VARCHAR(20),
    feature_snapshot JSONB,
    inference_latency_us INTEGER,
    aggregation_latency_us INTEGER,
    metadata JSONB,
    PRIMARY KEY (id, timestamp)  -- Composite key required for TimescaleDB hypertable
);

CREATE INDEX idx_ensemble_predictions_timestamp ON ensemble_predictions (timestamp DESC);
CREATE INDEX idx_ensemble_predictions_symbol ON ensemble_predictions (symbol, timestamp DESC);
CREATE INDEX idx_ensemble_predictions_action ON ensemble_predictions (ensemble_action);

SELECT create_hypertable('ensemble_predictions', 'timestamp', if_not_exists => TRUE);
SQL

# Create remaining tables (model_performance_attribution, ab_test_experiments)
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -f migrations/022_create_ensemble_tables.sql 2>&1 | grep -E "CREATE TABLE" | tail -5

# Verify all 3 tables exist
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "\dt ensemble*; \dt ab_test*"

2. Verify Model Checkpoints (2 minutes) ⚠️

# Check all 5 checkpoint files exist
ls -lh ml/trained_models/production/dqn/dqn_epoch_30.safetensors
ls -lh ml/trained_models/production/ppo/ppo_actor_epoch_130.safetensors
ls -lh ml/trained_models/production/ppo/ppo_critic_epoch_130.safetensors
ls -lh ml/trained_models/production/ppo/ppo_actor_epoch_420.safetensors
ls -lh ml/trained_models/production/ppo/ppo_critic_epoch_420.safetensors

# Expected output: 5 files (50-200 MB each)
# If missing: Copy from training checkpoints or retrain (see AGENT_78_DQN_PRODUCTION_TRAINING_SUCCESS.md)

3. Run Smoke Test (3 minutes) ✅

bash tests/paper_trading_smoke_test.sh

# Expected output:
# [TEST] Configuration file exists and is valid YAML
# [PASS] Config file valid
# [TEST] All 3 model checkpoints exist
# [PASS] All model checkpoints present (5 files)
# ...
# Tests Passed: 10/10
# ✅ ALL TESTS PASSED

4. Deploy Paper Trading (5 minutes) ✅

bash scripts/deploy_paper_trading.sh

# Expected output:
# ✅ Pre-flight checks passed
# ✅ All checkpoints verified (5 files)
# ✅ All services healthy
# ✅ Database tables ready
# 🎉 Paper trading deployment completed successfully!

Post-Deployment Monitoring

Daily Tasks (5-10 minutes)

1. Grafana Dashboard (Primary): http://localhost:3000/d/ensemble-ml-prod

• Panel 1: Confidence & disagreement (should be stable, <40% disagreement)
• Panel 2: Model weights (no wild swings, max 20% change)
• Panel 3: Per-model P&L attribution (all positive)
• Panel 4: Aggregation latency (P99 < 50μs)

2. PostgreSQL Daily P&L:

SELECT
    symbol,
    COUNT(*) AS predictions,
    SUM(pnl) / 100.0 AS pnl_dollars,
    AVG(ensemble_confidence)::NUMERIC(5,3) AS avg_confidence,
    AVG(disagreement_rate)::NUMERIC(5,3) AS avg_disagreement
FROM ensemble_predictions
WHERE timestamp > NOW() - INTERVAL '24 hours'
GROUP BY symbol;

3. Service Health:

docker-compose ps | grep "Up.*healthy"
docker logs foxhunt-trading-service --tail 100 | grep -i error

Weekly Tasks (30-60 minutes)

1. Review weekly performance report (Sharpe, win rate, P&L)
2. Check model weight adjustments (adaptive weighting)
3. Analyze high disagreement events (regime shifts)
4. Plan for Phase 2 advancement (if all success criteria met)

5-Phase Rollout Timeline

Phase	Duration	Capital	Max Position	Max Daily Loss	Success Criteria
1: Paper Trading	7 days	$100K virtual	$10K	$2K	Sharpe >1.5, Win >52%, DD <10%, P&L >$10K
2: 1% Capital	7 days	$50K real	$10K	$5K	Sharpe >1.5, P&L >$5K, Zero errors
3: 10% Capital	14 days	$500K real	$100K	$50K	Sharpe >1.8, P&L >$50K, A/B test wins
4: 50% Capital	21 days	$2.5M real	$500K	$100K	Sharpe >1.8, P&L >$250K, Hot-swap works
5: 100% Capital	Ongoing	$5M real	$1M	$250K	Sharpe >1.8, Return >40% annual, Uptime >99.9%

Total Timeline: 8-10 weeks from paper trading to full deployment

Exit Criteria: All success criteria must be met for the specified duration before advancing to the next phase. Any failure triggers rollback to the previous phase.

Rollback Procedures

Scenario 1: Daily Loss Exceeds Threshold

tli trading emergency-stop --reason "Daily loss exceeded"
# Investigate: All models losing? Or just one?
# Action: Disable failing model or halt trading for manual review

Scenario 2: High Disagreement (>70% for 1 hour)

# System automatically reduces position sizes by 50%
# No halt needed (graceful degradation)
# Investigate: Market regime shift or model issue?

Scenario 3: Single Model Failure (>3 errors)

# System automatically disables failed model (circuit breaker)
# Ensemble continues with 2 remaining models
# Investigate and fix, then re-enable: tli ensemble enable-model --model DQN

Scenario 4: Complete Ensemble Failure

# CRITICAL: Immediate halt
tli trading emergency-stop --reason "Ensemble catastrophic failure"
tli trading close-all --aggressive --max-slippage 10
curl -X POST http://localhost:8081/api/v1/ensemble/disable
curl -X POST http://localhost:8081/api/v1/config/revert-baseline
# Recovery Time Objective: < 5 minutes
