The 68%->95% lever from §176h.C2, mechanized. Reconciliation belongs INSIDE the wave: a banked
draft's declarations become the TU's, so a sibling clash hardens into a file clash and post-bank
recovery is measurably worse (18 parked drafts still MATCH, only 1 survived after their wave banked
vs 5 before).
AUTO-FIXES, each re-verified with match_one and REVERTED if a byte moves (a declaration change is
a codegen change, §176f):
* COSMETIC-TYPEDEF two names for a structurally identical struct -> adopt the other. Compared by
BODY, never by name (OtBlk_80015498 == OtBlk_80016450; Elem12 != B12). This body comparison is
also the answer to §176h.C's spelled-name limit.
* SIGNEDNESS / ALIAS / ARRAY-VS-SCALAR -> adopt the TU's spelling, fixing the use site.
* DEFPARAMS (NEW LEVER) -> adopt the TU's parameter types on the DEFINITION and re-narrow with a
shadowing local: `void f(s32 a0_p) { s16 a0 = (s16)a0_p; <body unchanged> }`. One textual
insertion instead of rewriting every use site, and the cast emits the same sll/sra pair.
Byte-identical on both cases tried.
REFUSES, with named reasons, because these are decisions and not edits: DIFFERENT-STRUCT (two real
layouts for one symbol), IMMOVABLE-TU-DECL (gate_main reverts src/, so it needs its own commit +
rebuild + R22), DEF-SIDE-RETURN (adopting the TU's return type usually costs the match -- measured
on func_8001ABBC), and BROKE-MATCH for anything its own verification rejects.
Measured on wave P's leftover slate: 6 -> 9 compatible, 3 auto-reconciled, 2 repairs reverted by
the tool's own byte check, 7 named for a human.
build_wave_atlas: --rank mass (main's gate cost is per SLATE, so ranking groups by member count
silently collapses a wide band to the smallest functions -- measured 60 cards/2,604 ins where 46
cards/4,829 ins were available), and the selector no longer counts ITS OWN OUTPUT as already-waved
(re-running with identical filters had been shrinking the pool 60 -> 46).
