The h_seq sweep's 137 "no matched unit for func" skips were ONE exemplar x 137
same-address members, not 137 distinct failures: func_8016191C @ ov_SC01_077,
band=mid, non-jr, 24 ins, ALL 137 members still INCLUDE_ASM stubs => 3,288 ins
left on the floor by a tool lookup miss (R35 again).
ROOT CAUSE (and it refutes the SESSION-27 checkpoint's own diagnosis, R14): the
exemplar is NOT "banked in a different binary". It is banked in ov_SC01_077 under
the SS37/SS73 asm-label alias — the byte-true body conflicts with the fleet-canonical
decl on BOTH SS73 axes (return void vs s32 AND params void*/s32 vs int/unsigned),
so it was banked zero-touch as
int aF8016191C(int, unsigned int) __asm__("func_8016191C");
extract_unit only ever matched a definition head literally NAMED func_<ADDR>, so
it returned None, and every caller reads None as "not matched".
FIX (tool-only, T0 blast radius):
- _alias_decl_for(): resolve `<ident>(...) __asm__("func_<ADDR>");` -> <ident>.
- extract_unit(): accept the alias identifier as the definition head, re-derived
PER FILE so one file's alias can never leak into the next.
- carry the alias DECLARATION into the unit (without it the sibling emits the
symbol aF8016191C and the body never lands at func_<ADDR>); the backscan now
walks PAST the alias line so the fn's own preceding externs are carried exactly
as for a plain definition, with a start<=alias_ln<=end guard against double-emit.
- R32: an alias decl with no findable definition now REFUSES LOUDLY instead of
falling through to _macro_unit and reporting "not matched" — the silent-skip
class this fix exists to delete.
Rejected the alternative the banking agent suggested (widen engine_core.h's decl
void->s32, drop the alias): it addresses only SS73's RETURN axis while decl and body
also disagree on PARAMS, and it is a T2 fleet-shared edit where the alias is T0.
VERIFIED: unit extracts with externs + exactly one asm label; remap_hseq produces a
sibling draft; rtu_match 3/3 MATCH (24 ins) in the real TU (ov_SC01_000/001/004).
make tools-health RC=0. The whole-binary byte-gate remains the sole arbiter (G3/P9).
