/**
 * Logger Consolidation Tests - RED Phase
 *
 * This test file documents duplicate logger implementations across the codebase
 * and defines the unified logger interface that should be implemented in the GREEN phase.
 *
 * Duplicate Logger Implementations Found:
 *
 * 1. packages/postgres.do/src/cdc/logger.ts:
 *    - CDCLogger class with LogLevel enum (DEBUG=0, INFO=1, WARN=2, ERROR=3, SILENT=4)
 *    - SubscriptionLogger for scoped logging
 *    - LogEntry interface with level, levelName, message, timestamp, subscriptionId, context, error
 *    - Circular buffer for event capture
 *    - Console handler with color support
 *
 * 2. packages/postgres/src/storage/tiered-orchestrator.ts:
 *    - Logger interface with debug, info, warn, error methods (string only)
 *    - Simpler interface than CDCLogger
 *
 * 3. packages/postgres/src/routing/tenant-router.ts:
 *    - TenantRouterLogger interface with log(entry), debug, info, warn, error methods
 *    - LogLevel type ('debug' | 'info' | 'warn' | 'error')
 *    - LogEntry interface with level, message, tenantId, correlationId, timestamp, data
 *
 * Differences in Implementations:
 * - CDCLogger uses numeric LogLevel enum; tenant-router uses string union type
 * - CDCLogger has event capture/circular buffer; others don't
 * - CDCLogger supports subscriptionId; tenant-router supports tenantId/correlationId
 * - TieredOrchestrator has simplest interface (just methods)
 * - Only CDCLogger has color support for console output
 *
 * Unified Logger Requirements:
 * - Support all log levels: debug, info, warn, error, (plus silent for filtering)
 * - Support structured logging with arbitrary metadata
 * - Support child loggers with scoped context (subscriptionId, tenantId, etc.)
 * - Support log filtering by level
 * - Support custom handlers/formatters
 * - Support event capture for debugging
 * - Cloudflare Workers compatible (no Node.js dependencies)
