Its 0/137 was the §94 TYPE-CARRY signature: the draft defines `typedef struct {…} Sp_80175DA8;` at
FILE scope, and remap_hseq templates the BODY but not the type, so every sibling compiled without it.
§94's remedy is the shared engine_types.h lift (right for func_8016B6BC, whose four types were
transitively referenced). But the cheap remedy was already in the same draft: it carries S_AF634 at
BLOCK scope and that templates fine, because a type declared in the body travels WITH the body.
Sp_80175DA8 is used by that function ONLY (7 mentions, 6 inside the body, 0 elsewhere), so moving it
into the body is byte-neutral (d19c9580 unchanged), T0, zero blast radius — versus editing a header
included by 140 binaries with uniquify/collision care and an R22.
Re-swept: 137/137, 0 failed. R22 clean-fleet 140 passed / 0 failed of 140.
MEASURED: fn-count 318,720 -> 318,857 (+137); instr 84.2 -> 84.4% (+31,647 ins); distinct-code
73.9 -> 74.4% (+129 unique fns).
§99 AND §100, AN HOUR APART, ARE THE SAME LESSON: both times the cookbook's named remedy was the
expensive fleet-wide one (524-site decl conform / shared-header lift) and the correct fix was
DRAFT-LOCAL (K&R definition / block-scope typedef). Before editing anything shared, ask what the
smallest scope is that still travels with the body.
