FStrateGenerationParams::Lerp blends the hand-written VF_STRATE_PARAM_FIELDS list, not the struct. Add a field to one and not the other and it compiles, tests green, and silently takes its default inside every Gradient/Interleaved transition band -- terrain that changes shape at the boundary and nowhere else. CODEMAP has warned about this in prose for a month. The test expands the X-macro a third way (after LERP and SNAP), into a list of names, and diffs it against the struct's UObject reflection. No fixture, no world -- a shape test, instant. GExemptFieldNames is empty on purpose: every reflected field is covered today, so an exemption has to be written down as a decision rather than happening by omission. The stakes rise with the world composer, which intends to invent parameter sets through this same Lerp: a missing field would then be constant across every invented strate, with nothing to notice it by. (Its CODEMAP §3.12 row lands in the following commit, which also touches that file for an unrelated reason.)
