Drew T 7f2f314896 docs(phase-20): -O0 ×134 rollout is INVALID — cluster is overlay-local, not reach-134 (R14)
- byte-proven: only 1/134 overlays shares ov_SC01_077's -O0 cluster bytes; the 6 matched
  -O0 fns reference per-overlay data addresses (func_8013B568 -> D_80187270 in ov_SC01_077
  but 0x80182B04 in ov_SC01_005), so they're overlay-LOCAL, not ×134-shareable. The
  Phase-18/19 'reach-134' label conflated function-present with byte-identical (R14).
- the §18 split infra (rollout tool + Makefile %_o0.o pattern + PROVIDE .ld) was built and
  byte-validated to compile/link a 2nd overlay; the whole-binary gate then exposed the
  per-overlay-data wall -> reverted (the finding is the deliverable, P9).
- -O0 rollout = ×1 per-overlay-unique re-matching (~0.2-0.3%), NOT +0.6% free -> SKIP.
  cookbook §18 corrected; fleet unchanged 58.82%, 136/136 byte-identical.
