+### (a) Exact authorized diff — PASS

++            target.parent.mkdir(parents=True, mode=0o700, exist_ok=True)

+
+The zero-context hunk is `@@ -709 +709 @@`. No other harness hunk or changed line exists. This is the authorized fixture-copy-loop repair only.
+
+### (b) Security-bearing bytes / D4 mechanism unchanged — PASS
+
+The hunk range is **old L709 / new L709**, which does not intersect these byte-compared ranges:
+
+| Surface | Line range | v10 SHA-256 = repair SHA-256 |
+| --- | --- | --- |
+| B5–B9 closure, bytecode, environment, and child-launch controls | L351–L575 | `3dcdcf75c8b1dea0a1f8888cf1e49a52aba51e7e41f447b80cf407d84533eb2e` |
+| D4 generated lifecycle extension | L159–L251 | `4bdc047f7494029d951763555a797103ca25da647b255b287378771d20da209b` |
+| D4 runtime assertions, including `lease_anchor_registered` | L579–L665 | `75620f25829fa7e176af8b342b2935d45afb546d821d45bf478c51e95f6918ca` |
+| D4 orchestration and `--runs` parser | L749–L849 | `a28c36296b2ba8fffe77912b7e25b793047393bae79a9242df1727bd21ab2f92` |
+
+Thus B5–B9 assertions and all D4 generation-mechanism bytes are identical to v10. The sole hunk is inside `isolated_environment`, outside those assertion/mechanism ranges.
+
+## Required negative checks
+
+- **L704 unchanged:** byte-identical (`target_agent.mkdir(parents=True, mode=0o700)`); the L704-only slice hash is `5c077090950c1cc68b53ac4d06280dd2b5d91bd34b28f1cc8d26d0d9eb8dbe41` on both commits.
+- **Launcher flags unchanged:** B5–B9 slice includes launcher L511–L517: `-s -S -B` unchanged.
+- **Broker flags unchanged:** B5–B9 slice includes broker L551–L556: `-I -S -B` unchanged.
+- **`--runs` unchanged:** L840 remains `default=3, choices=(3,)` in the byte-identical L749–L849 slice.
+- **Assertions intact:** `lease_anchor_registered` remains at L594–L596 in the byte-identical L579–L665 slice; no B5–B9 assertion is softened, removed, or repointed.
+- **Absent from the harness delta:** P5, P6, P2-banking, retry-laundering, and live/prod-path changes. The exact one-line diff contains only the fixture directory `exist_ok=True` addition.
+- **Fixture scope:** no other fixture line changed; `git diff --check` is clean.

+## Guard 2 — authorship independence
+
+These review-document bytes were authored by this independent review session, not by repair author `ms-p3-fix`; this session did not build or modify the reviewed harness. The review was static/byte-only and did not execute the harness or launch a broker.
+
+## Guard 3 — publication boundary
+
+This document is committed separately on top of `93a5fd018d26f16aa58a3ec1afc0c9bc83935fed`. Its publication commit must leave the reviewed harness Git-object SHA-256 at `3a4b625a474ab31c53af7758464f51fe729a14201a77c049cceb9eafb607b5c8`.
+
+**TERRA §3 v11 PASS.** This is a null-security-delta byte review only; FIRE remains separately gated on Mos.
