StatValidation.ValidateRoleUsage walks every PerformanceStat field on every
behaviour and refuses a StatSource.Quality term whose Role is not in the
design's own declared Roles -- wired into AetheriaStores.Open and
CultRecordRefs.Upsert alongside the existing heat/modifier/power-supply
checks. Lot.QualityForRole already falls back to workmanship for a role an
old lot never rolled (forward-compat for a role added after minting); this
is the other direction: a term naming a role the design never declared at
all is an authoring mistake, not a lot predating the role, and must fail
loudly.
RoleAuthoringTests.cs pins three rules with both a positive and negative
control: Upsert refuses an absent-role term but accepts a declared one, and
two products of one design with different ProductRole means mint lots that
resolve a role-termed stat to different, deterministic values.
tests/mutation_tests_stats_power_cut8.py (this repo's own numbering follows
cut7.py's brownout work) mutates ValidateRoleUsage in both directions
(never-refuse, always-refuse) and QualityForRole's fallback, plus
ItemManager.CreateLot's mean read -- all six behave as declared.
