Bounded probe (SESSION-13, token-free) that REVERSED the same-session "fresh
reach-138 well is spent" verdict. Target func_8014CD80: 138 live, 0 matched, NO
DEFINE macro, a universal body (only universal callees + param offsets, zero
overlay-local D_* refs), clean MATCH draft from batch-1.
- Blocker was a def-side header decl: engine_core.h DEFINE_func_8014CD0C()
forward-declares it `void func_8014CD80(s32,void*,void*)` while the byte-true
def is `int func_8014CD80(s32,u16*,u16*)`. gate_stage's arity pre-pass is
param-COUNT-only (misses return/ptr-type); §54 reconcile_def_sig fixes the
wrong direction.
- One byte-neutral header edit (void->int, void*->u16*; call site passes u16[3]
arrays + ignores the return -> codegen unchanged) -> harvest_verify banked x1
BYTE-IDENTICAL -> dedup_propagate --addr propagated 138/138 overlays
byte-identical (live 138->0) -> R22 clean-fleet 140/140.
- Fleet 78.7->78.8% instr, 88.22->88.26% fn-count from this one family;
tools-health green (dedup 1851/0).
Quantified market (decision-log 2026-07-23): of the 75 fresh (>=100-live)
families, 46 carry an engine_core.h caller forward-decl, 38 SIMPLIFIED = the
func_8014CD80 pattern -> each a candidate x138 (~+1.5-2.8pp instr). NEXT: build
tools/fix_header_decl.py + a fresh-family wave. func_80165CA0's 0/135 was a
non-universal BODY (different failure mode), not this blocker.
