+## Operator review of the #1915 ACK (2026-11-01)
+
+- **Status.** P0/P1 (#1914), the 13-layer scratchpad (#1915) and the
+  `r(V,V)` diagonal (xlog#5) are merged. The scratchpad is the preserved
+  scientific direction future experiments are read against. It is not a
+  supervisory plan that must approve each mathematical test.
+- **C0, three-way closure parity, is a correctness check, not a Staunen
+  claim.** It runs a scalar BFS oracle, `Cube::closure` and XLOG's compiled
+  recursion on the canonical 12-pair cycle (diagonal checked on each) and
+  400 frozen seeded graphs, compared as sets with bag behaviour checked.
+  Delivered as xlog#6, test only, merged 2026-11-01 11:54 UTC: P1 is accepted.
+- **MUL (H12).** One prediction and outcome is one calibration
+  observation, not a calibration. Competence and overconfidence need a
+  history of predictions and outcomes under a declared scoring rule. The
+  ACK's fixture is a trace-integrity test, not a demonstration of H12.
+- **P0 ordering leak: its own gate, before P5/P6.** The generator puts the
+  withheld true edges first in `candidates` and appends noise stimuli after
+  the true ones, so index order leaks the labels. It must be fixed, with a
+  test that a policy reading only indices scores at chance, before any P5/P6
+  result is interpreted. It does not affect P1's closure result.
