CARD K1-18  (pre-registered 2026-09-26 02:38:17 -0700)
Base: k16 (11 hunks; real residual: 0xfc add-esp schedule; 0x1d49 magnitude_squared2d term order).
Mechanism (memory, x87 operand sort decoded + S3-V3/V6): x87 term order for INDIRECT leaves keys on the base
  pointer temp's ID mod 4, and pointer temps are value-number temps whose ID = base + VN ordinal; code-NEUTRAL source
  statements that VC7 folds away still add VN entries (bipeds SET_FLAG precedent). K1-12 showed such a flip here.
  normalize2d/magnitude2d read alignment through the inlined pointer v (indirect leaves, temp base).
Evidence: five code-neutral /Od statement forms we lack (D, each attested separately):
  (a) DISABLED: "if (!suppress_output) error(2, debug_string);" (/Od 0x48e807) [K1-12 alone: weight order flipped
      the wrong way at the k10 stage];
  (b) allegiance print: "broken ? "broken" : "still holds"" (/Od 0x48dc13; January references only "still holds",
      consistent with folding under "if (!broken)");
  (c) forced block: a separate short copy of possibility_count printed as the first %d (/Od [ebp-0x13bc]);
  (d) success tail: "any_protagonist_considered = TRUE;" BEFORE "total_possibility_weight += weight;" (/Od
      0x49064a);
  (e) packet order: communication_type, damage_category, target_unit_index, dialogue_type_index, ... (/Od 0x49092f).
Plan: each alone on k16 (5 compiles), then the full set (all five, NOT a yield-selected subset).
Prediction: each alone may flip 0x1d49 and/or the weight order; the full /Od set is the principled candidate. A
  yield-selected subset would be reported as such (not as evidence).
