+- Repair 11 (after the first S5 submission b2dbda8c956643a2a972e8bcf7416038a3f70b2c):
+  - Its exact-S native passed: driver exit 0, execution passed, cleanup errors empty,
+    R-A/R-B and O-A/O-B compared with 0 differences, sealed (native-b2dbda8-r01, 5954 files).
+    This exercised the whole S5 driver path on real data.
+  - Its formal validation (report c02eda130f6c49e6bcf2ec4a7c1e8f69): p28-02-eq-unit passed
+    (161 tests); p28-02-eq-native-verify failed, exit 1, 'Operation not permitted' on the
+    fixture. The Runner validation seatbelt cannot read data under the home directory outside
+    the checkout and the task runtime, and verify_eq read the original fixture and read-only
+    inputs. Kept as a failure; the b2dbda8 bundle is retained but not reused.
+  - Fix: run_eq seals copies of the fixture and the nine read-only inputs inside the bundle
+    after checking them against the admission pins; verify_eq recomputes the pins from the
+    checkout and those sealed copies by the same rules (bundled_inputs). No permission,
+    policy, timeout or Runner configuration change.
+  - Final unit evidence for repair 11: UNIT_OUTPUT_S5_ATTEMPT_06 (162 tests OK in 120.853 s,
+    Python exit 0, outer 120.983 s; same bytes as UNIT_OUTPUT.txt, SHA-256
+    846ab3b45705f269a81181c818dc5e3b8bc0057863794d59e8d641fe5a4e4c32) and
+    UNIT_OUTPUT_S5_SEATBELT_06 (the same suite under the Runner validation seatbelt profile,
+    run locally: 162 tests OK in 120.930 s, Python exit 0). Local runs are not formal
+    validation.

 Next: Runner submit → exact-S native 7 phases → bundle → p28-02-eq-unit and
 p28-02-eq-native-verify → fresh independent Opus review of all 6 conditions → normal
 qualification, approval, integration and final → OPT/whole-unit. 23/88、4/30は不変。
