Cycle 3 merged 22 claims (worker A's 8 new plus 9 gp rows, worker C's 6 pure-C
rows) at 137 regions / 128 distinct bodies, and closed every near-miss that
Phases 5-7 recorded in the reachable set: 0x800F3160, 0x800F8AEC, 0x800F8B58/6C,
0x800F8FE4, 0x80102B10 (maspsx=off), 0x800F7FB4 x3 (a cc1 loop-shape artifact),
0x8009E8D0 x2 (ordinary matching).
Worker C's SDK-shape investigation refuted its own premise: the COP2 shapes are
reachable, the blocker was never the missing SDK headers, and the stack accessor
needs no asm at all. The 8 COP2/syscall regions are parked pending the
developer's inline-asm convention decision.
Recorded as results, not footnotes: three rules that were tested and bounded. The
commutative-operand rule's direction is right but its trigger fails for a literal
base in a counted loop; the do/while loop rewrite does not transfer to
0x800FBF5C; and the reorg class is a cc1 reorder thread-fill decision that no
assembler can perform for a conditional branch, so it is a bounded negative
rather than a harness gap.
