Drop a file. Get a tdoc.

A tdoc is a single file with two faces. To humans it's a normal PDF that opens anywhere — Preview, Acrobat, every browser, every email client. To AI agents it's a typed AXON tree the model reads directly, no rendering, no parser. Same file. Saved with the .pdf extension. There is no zip and no folder. There is one file, and that file is your tdoc.
