- The draft calls ((void(*)(void))func_80142C84)() but nothing declares that symbol above the
splice: it is DEFINED by DEFINE_func_80142C84() in engine_core.h, so gather_externs has no
extern line to harvest, and the member TU instantiates the macro BELOW our function.
- The wrong guess was the useful step: a no-prototype `extern s32 func_80142C84();` turned
`undeclared` into `conflicting types` — a DIFFERENT error, proving the diagnosis right and the
type wrong. Synthesised from the macro's own definition head -> MATCH (34 ins) -> 136/136.
- NEW macro_def_sig_map() (1,878 signatures): the complement of header_sig_map(), which reads the
externs a macro emits FOR ITS CALLEES; this reads the signature a macro DEFINES. Cookbook §121.
- ALL THREE byte-identical stragglers carried since SESSION-24 are now closed: func_80146750
137/137 (T84), func_801759D8 137/137 (T93), func_80142B2C 136/136 (T95) = 410 members, and not
one was a compiler wall (a signedness-wrong header decl, a type-name collision, a missing extern).
- Blast radius 0 (74 further families re-swept). FOUR data points now: only §117 (wrong LOGIC)
generalised at 1,209 members; §118/§120/§121 are path-reachability gaps worth ~one family each.
- GATES: R22 clean-fleet 140/140; dedup 1886/0; 0 NON_MATCHING (G4).
- METRICS: fn-count 91.88 -> 91.96% (+273, exact) · instr 87.3 -> 87.4% (+12,296) · distinct +0
(both byte-identical families — §111 predicted exactly that).
