-- Trinity Console Database Migration
-- Run this AFTER Arbiter 3.0 base tables are created
-- Date: April 1, 2026

-- Track every tier change and subscription lifecycle event

    new_tier INT,
    change_reason VARCHAR(255), -- 'upgrade', 'downgrade', 'payment_failed', 'manual'
    changed_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP

    admin_username VARCHAR(255),
    action_type VARCHAR(50), -- 'force_sync', 'manual_role_assign', 'bulk_update', 'tier_change'

-- Enhance subscriptions table for MRR, grace period, and referrals
ALTER TABLE subscriptions

ADD COLUMN IF NOT EXISTS grace_period_started_at TIMESTAMP,

-- Indexes for performance
CREATE INDEX IF NOT EXISTS idx_player_history_discord_id ON player_history(discord_id);
CREATE INDEX IF NOT EXISTS idx_player_history_changed_at ON player_history(changed_at DESC);
CREATE INDEX IF NOT EXISTS idx_audit_log_performed_at ON admin_audit_log(performed_at DESC);
