Pull Request Overview

Adds a recursive fetch for nested logical files in the DFU service and exposes it via a new helper on the LogicalFile object.

• Introduces recursiveFetchLogicalFiles in wsDFU.ts to gather subfiles and superfiles in a single call
• Adds fetchAllLogicalFiles on LogicalFile to invoke the new recursive method
• Does not include accompanying documentation or tests for the new recursive behavior

packages/comms/src/services/wsDFU.ts:18

• Add a JSDoc comment above this method to explain its purpose, parameters, and return value for future maintainers.

    async recursiveFetchLogicalFiles(superFiles: { NodeGroup: string, Name: string }[]): Promise<string[]> {

packages/comms/src/services/wsDFU.ts:32

• Add unit tests covering nested recursion, including scenarios with multiple levels of superfiles, to ensure correct termination and result flattening.

        return logicalFiles.concat(childSuperFiles.length ? await this.recursiveFetchLogicalFiles(childSuperFiles) : []);

packages/comms/src/ecl/logicalFile.ts:180

• The recursiveFetchLogicalFiles method expects objects with NodeGroup and Name properties, but this may not satisfy that shape. Consider passing { NodeGroup: this.NodeGroup, Name: this.Name } or similar.

        return this.connection.recursiveFetchLogicalFiles([this]);
