The Companion session
Try it now with the sample document: upload the fixture ledger and watch the Companion produce an organized, cited working paper — sealed, downloadable, and independently re-derivable. This DEMO accepts only the sample (deny-by-default, made visible); a real engagement runs under your own sealed store.

2. Upload it back (or just run it one-tap):
Any other document is refused — the demo's deny-by-default gate, made visible. A real engagement accepts your real documents under your own sealed engagement store (your data never leaves the governed perimeter, and the platform structurally cannot monetize it).
