GROUND-WP-0002 T01 ruled the edition dataset authoritative, so the engine
must stop inventing Problem values and suits. Problems.csv carries 5
problems per scenario worth 2,2,2,3,3 (total 12) with a required_solution
each; the stand-in deals 3 worth 1,2,3 (total 6). GR-E01's thresholds of
5/7/9 are ordinary against 12 and unreachable against 6 -- which is why
the maintainer's last game ended 0 scores and winners nobody, and why
'GR-E01 unreachable below 5 seats' was carried as a rules gap. It was
never a rules gap.
Measured before declaring: AM-4a has 3,798 lines of headroom and a CSV
crate costs 21,613 marginal (csv 14,291 + csv-core 3,360 + ryu 3,962;
itoa/memchr/serde/serde_core are already present and free). 5.7x over, so
the shipped runtime cannot gain a CSV parser and that is settled by
measurement rather than preference.
The ADR's third question is the one that bites: Problem values and suits
become part of GroundState, which is hashed, so every recorded state hash
changes. A content import that quietly invalidates every hash in a
project whose central invariant is replay determinism is not a
data-loading change.
Chaos d8=7, no override.
