- CORRECTION (R14/P9): T84's '137 banked = all of 0x80161c98' is WRONG and committed wrong in
commit:1193. The 137 were func_80146750 (a byte-identical straggler), banked 1-per-overlay in
<ov>_after.c; 0x80161c98's members were still stubs. I assigned a count to the family I had
been looking at without deriving it — third instance today of that error class. The
--fix-def-sig-is-harmful finding itself stands (it unblocked func_80146750 x137).
- THE REAL BLOCKER was a flag OFF-DIAGONAL, not a defect. 0x80161c98's byte truth is (int,u32)
-> sltiu; engine_core.h says (s32,s32); and an in-TU decl disagrees with the def. The levers
pull opposite ways: --fix-def-sig bends the DEFINITION to the header; --normalize-self-decls
bends the DECLARATIONS to the definition. both-on -> slti DIFF (T79). both-off -> correct
sltiu but 'conflicting types' (T84/T88). NSD-only -> 138/138 (T89). Three sweeps across three
sessions tested only the diagonal of the 2x2. Cookbook §119.
- T90 blast radius: 23 more (NSD-only) across the remaining still-zero families — targeted, not
general; recorded so it is not over-projected.
- GATES: R22 clean-fleet 140/140; dedup 1886/0; 0 NON_MATCHING (G4).
- METRICS: fn-count 91.84 -> 91.88% (+161, exact) · distinct-code 69,593 -> 69,744 (+151).
