StatValidation.ValidateHeatResponse now refuses NaN in any of the four heat-response
fields, a zero-span range (Minimum == Maximum -- Tractor Beam's exact bug), and a
plateau whose low or high edge pokes past its bounds, matching the R-heat ruling and
the Performance() comment that already claimed this was enforced. The writable-path
hole is closed for every path this repo owns: CultRecordRefs.Upsert (AetheriaStores.cs),
the one function every tool, test and migration script writes catalog documents
through, validates before a write reaches disk instead of waiting for the next Open().
CultCache Studio's generic editor bypasses Upsert and still has no per-document
validation hook -- that hole is CultLib's, not this repo's, and stays named in the code
rather than silently assumed closed.
EquippableItemData's four heat fields get non-degenerate defaults (0/100/50/20, the
same shape HeatResponseTests already hand-authors) because dozens of existing test
fixtures across the suite build designs that never cared about heat and defaulted into
the same zero-span trap Tractor Beam shipped with; enforcing the zero-span refusal
without this would have required touching every one of those fixtures instead of the
root cause.
Four new mutations pin S7's survivors, each with its own dedicated test rather than a
coincidentally-sensitive existing one: out-of-bounds semantics (return 1f instead of 0f
outside bounds), the plateau-clamp validation's two sides, and a Quality term ignoring
its own exponent (StatsReadTheLot's Exponent = 1 everywhere could not tell "reads the
exponent" from "always uses 1"; the new test uses Exponent = 2). Performance()'s own
runtime plateau clamp is separately confirmed dead code -- the outer bounds guard makes
it unobservable at every input, verified by an exhaustive numeric sweep -- and is
recorded as such rather than forced into a fake kill.
80 tests (9 new), 17 mutation cases in tests/mutation_tests_stats_power_cut1.py, all
green.
