    Interface ILogger

    Structured logger. All framework and application logging goes through this interface — never console (AI_GUIDELINES §11.6).

    const logger = ctx.services.get<ILogger>(CAPABILITIES.LOGGER);
    logger.info('User created', { userId: user.id });

    const requestLogger = logger.child({ requestId: ctx.id });

    interface ILogger {
        level: LogLevel;
        child(bindings: LogMetadata): ILogger;
        debug(message: string, metadata?: Readonly<Record<string, unknown>>): void;
        error(message: string, metadata?: Readonly<Record<string, unknown>>): void;
        fatal(message: string, metadata?: Readonly<Record<string, unknown>>): void;
        info(message: string, metadata?: Readonly<Record<string, unknown>>): void;
        trace(message: string, metadata?: Readonly<Record<string, unknown>>): void;
        warn(message: string, metadata?: Readonly<Record<string, unknown>>): void;
    }
