Drew T 8e78cd7ce8 feat(phase-21): cont.7c — giant approach VALIDATED (func_80176D94 structurally matched) + recipe §27
- Drew chose GIANT SESSION. Validated the giant-matching approach end-to-end:
  hand-matched func_80176D94 (152 ins) to STRUCTURALLY-MATCHED (calls/constants/GPU-packet
  all byte-correct) via the recipe: cached Ghidra-C + call-matching callee decls (arg-arity:
  func_80177784 called 3-arg vs canonical 4-arg) + §17 register pins (regalloc-shift) +
  sibling func_80176FF4 idioms (coord strength-reduce, GPU linked-list pointer).
- Residual = pure regalloc-coalescing (2 extra callee regs vs target caller-saved/-reuse)
  -> saved .run/backlog_drafts/func_80176D94.c as grinder/wave fuel (permuter territory).
- cookbook §27: the Giant matching recipe (5 steps + the pin-reuse caveat + the
  accumulator-coalescing residual class). Giants reach structurally-matched FAST; the last
  mile is regalloc -> isolated-agent + permuter work, not main-loop serial grind.
- Giant pool is ~18 tractable (152-284 ins) + 2 monsters, bigger than the assess's 8.
- NEXT: worker_wave over the giants (§27-seeded) -> gate + propagate ×134. fleet 63.17%.
