Keep an exact local file inside a portable UD package
LOCAL EXPORT COMPATIBILITY · NOT A MANAGED CONNECTOR
A renamed attachment may be difficult to match to the file you originally received.
Try it
Choose one existing file, not a directory. The filesystem adapter accepts its bytes, calculates SHA-256 and packages them without opening the source application. Export a UDS for a hash-sealed snapshot or UDR while the package changes. Keep the original file as well as the package. A recipient can verify the embedded bytes with the CLI and extract the exact raw UD from the browser-ready copy.
node packages/udify/src/cli.mjs import filesystem source-file result.uds UDS node packages/udify/src/cli.mjs verify result.uds
Limits
A matching hash does not say that the original file was correct, safe or authored by a particular person.
Does this convert a PDF into structured paragraphs?
No. This local profile preserves source bytes; it does not parse PDF or Office content.
