# Vendored edition data — provenance

**Not ours.** This directory holds a copy of content owned by the
`ground-game` repository, vendored under ADR-0011 Decision 2 because the
build must not depend on a sibling checkout that CI does not have.

```

`make edition-check` compares this against `../ground-game` when that
repository is present, and reports **`upstream not checked out`** as a
distinct outcome when it is not — never a pass. An absent check is
reported absent, not treated as satisfied (the shape ADR-0009 used for
`node`).

## What may not change under this revision

Per GROUND-WP-0002 T01's contract: `point_value` and
`required_solution` are **authoritative and frozen within `r0`**. The
engine hashes game state and both values are *in* that state, so a silent
change would rot every recorded scenario expectation. A change to either
is a new revision (`-r1`), and this digest is what notices.
