# Acceptance fixture custody

This action orchestrates exact public prerequisite preparation in a fresh hosted
checkout. Do not run it on a shared workstation: existing inputs are refused.
Every producer, aggregate collector and tagged release reader must prepare the
same bytes before source identity/export observation. Generated fixture roots remain observed by the unchanged source APIs.
The authenticated TLC tool uses the explicit external provider boundary, so it
cannot enter authored source/export inventory; no source exclusion is introduced. Retain upstream licenses and fixed archive hashes/lengths.

Use [README.md](README.md) for ordering and run actionlint after edits.
