/**
 * This function resolves custom flags for an event based on its actions.
 * Flags are not stored to the event state or any database directly, instead they are always computed/evaluated from the event actions.
 *
 * Processes accepted actions in chronological order, evaluating flag conditions
 * at each action step. Flags can be added or removed based on action configurations
 * and conditional logic. Duplicate flags are filtered out.
 *
 * @param event - The event document containing actions and metadata
 * @param eventConfiguration - The configuration object for the event type defining action rules and flag behaviors
 * @returns An array of unique custom flag IDs that apply to the event after processing all non-meta actions
 *
 * @example
 * const flags = resolveEventCustomFlags(eventDoc, config);
 * // Returns: ['flag-1', 'flag-3']

/**
 * Computes all flags (inherent, action status, and custom) that should be attached to the given event,
 * based on its actions and event-specific configuration.
 *
 * Flags are determined by combining:
 *  - Action status flags (format 'ActionType:ActionStatus')
 *  - Inherent flags (e.g. incomplete, rejected, correction requested, potential duplicate, edit in progress)
 *  - Event type-specific custom flags defined in the event configuration
 *
 * @param event - The EventDocument containing the action history and payload
 * @param config - The EventConfig providing rules for custom flag evaluation
 * @returns An array of flags currently relevant/applicable to the event
