Research note rev 2: G2' falsifier fix round (mode n, anchor kinds, gate restated)

- mode n (anchors = full native inspections only, S7 literal): record-s
  0.68-0.77x vs union u 0.50-0.54x; ~31% of u's anchor references are
  earlier G2' residual records, so D2 recommends G2' with S7/3.11 amended;
- gate W4.2 FAIL as registered; record_s shown with run_s, useful-work
  units and perf instructions (n=3); no relaxation of the 0.5 clause;
- oracle agreement restated as a cancellation, not a validation.
