1# External payload fixture
2
3OneNote 2010 authored an empty attachment and a 1 KiB attachment with
4`tools/native/external-assets.ps1`. The retained native section is in `native/`.
5The fixture generator converts all file-data declarations into the documented
6external representation while retaining their identities and exact payloads.
7The `read/` capture is an independent fresh-cache OneNote reopen; `payloads.json`
8contains the native attachment hashes. `provenance.json` records source hashes.

15The generator creates a new destination and requires reserved fragment space.
16It is a fixture converter, not a concurrent publication API.
