pool_window.rs shows the Destroyer's raw tokens: "200.0" "Size_X" "Size_Y" "2000.0" "Size_Z" -- Size_Y is a bare key, so the 13 runtime values recovered earlier are real defaults, not a reader artefact. The filler reads each size field through sub_822FC5A8, which loads f31 from 0x8209fd28 = 0.0 at entry and returns it on a pool miss, then stores to +52. Nothing else in the 15876-byte filler writes +52, so the definition leaves a defaulted Size_Y at 0.0 and the runtime 200 is written later. Two corrections: the +48/+52/+56 comparison block builds a size-class bitmask against 1000.0 (constant 0x8209fd20), not a has-value mask; and both earlier Size_Y derivation candidates are refuted (one is a conditional pick, the other multiplies into a different struct).
