GROUND-WP-0002 T01: the edition dataset is authoritative

Ruled by the maintainer 2026-08-03. editions/ground-darvo-r0/ is the
source of truth for Problem values, required solutions, visibility and
priority, and the engine must import it rather than invent them. This
unblocks clay-borg and very likely dissolves
gr-e01-threshold-unreachable-2p.

The three sub-questions were not ruled, so proposed defaults are recorded
rather than blocking the import on them: which columns are authoritative
vs presentational; that point_value and required_solution may NOT change
within r0; and that a version bump is the directory name, so it shows in
a diff and is never silent.

The second matters most: the engine hashes game state and a Problem's
value and required suit are IN that state. If they can change under a
fixed revision name, every recorded scenario hash in clay-borg silently
rots. Hence 'no' rather than 'probably not'.

+The headline is answered. The three sub-questions were not, and rather
+than block the import on them, these are the **proposed defaults**; each
+is cheap to overturn and none is load-bearing for a first import:
+
+| question | proposed default |
+|---|---|
+| authoritative vs presentational columns | **authoritative:** `problem_id`, `scenario_id`, `visibility`, `hidden_priority`, `required_solution`, `point_value`. **Presentational:** `title`, `problem_text`, `symbol_id`, `front_rules`, `reveal_effect`, `unresolved_effect`, `back_design_id` |
+| may `point_value` / `required_solution` change within `r0`? | **no** — a change to either is a new revision |
+| what a version bump looks like | the directory name: `ground-darvo-r0` → `-r1`. The engine pins a directory, so a bump is visible in a diff and never silent |
+
+**The distinction that matters** is the second: the engine will hash game
+state, and a Problem's value and required suit are *in* that state. If
+they can change under a fixed revision name, every recorded scenario hash
+in clay-borg silently rots. That is why "no" is proposed rather than
+"probably not".
+
+**Owed:** confirm or overturn the three rows above. Until then the engine
+imports under them and says so.
