-- Migration: Add review_events table

CREATE TABLE IF NOT EXISTS review_events (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    review_id INTEGER NOT NULL,
    event_type VARCHAR(50) NOT NULL,
    step VARCHAR(100),
    message TEXT,
    data JSON,
    created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (review_id) REFERENCES reviews(id) ON DELETE CASCADE

-- Create indexes for better performance
CREATE INDEX IF NOT EXISTS idx_review_events_review_id ON review_events(review_id);
CREATE INDEX IF NOT EXISTS idx_review_events_created_at ON review_events(created_at);
