CARD B6 (RF-U) written 2026-09-26 19:45:41 -0700 (clock-read), BEFORE compiling. Immutable; outcome appended.
Kind: STRIP TEST for B5 (keep only the /Od-dx9-attested part). Source b/B6.c = HEAD arms; device arm ends
  'if (!hw) success = FALSE; if (!success) { hw = NULL; error(...); }' (error kept with hw = NULL as in HEAD);
  'else { hw = NULL; }'; single 'return success'. i.e. B5 with the error() call put back in HEAD's block.
Prediction: == HEAD bytes (sha 719469..., jne -> second copy), like Lane C's A3 (which also had success = TRUE in
  the else arm). Confidence ~75%.

OUTCOME B6 (appended 2026-09-26 19:46:07 -0700): residual 400 [sha 9f2d9d45] - NEITHER HEAD nor January: the EBX constant-1 pin is lost
  (mov bl,1 / push 1 / test [esi+0xe],1; 147 insns) and the jne still binds to the LAST copy (+0x15e -> 0x183), the
  same failure as Lane C's A4. Prediction (== HEAD) WRONG. Strip-test meaning: the /Od-dx9 single-exit alone does
  not reach January; with the error() kept in the hw=NULL block it is worse than HEAD.
