# TERRA §3 — Probe-3 Bounded-Repair Re-Review v11
|
||
|
||
**Verdict: PASS (byte review only; no harness, broker, or runtime was launched).**
|
||
|
||
## Reviewed object (GUARD 1)
|
||
|
||
- **Branch:** `feat/827-gate0-probe`
|
||
- **Reviewed object = `93a5fd018d26f16aa58a3ec1afc0c9bc83935fed`**
|
||
- **v10 baseline:** `ce5ba762051354338889959bfce2b0381f4a4e2a`
|
||
- **Harness:** `docs/compaction-refresh/probes/p3_d4_focused_run.py`
|
||
- **Verified harness sha256:** `3a4b625a474ab31c53af7758464f51fe729a14201a77c049cceb9eafb607b5c8`
|
||
|
||
Fresh verification fetched `origin/feat/827-gate0-probe`; local `HEAD` and remote branch both resolved to the reviewed full SHA before hashing the Git object.
|
||
|
||
## TERRA §3 null-delta gate
|
||
|
||
### (a) Exact authorized diff — PASS
|
||
|
||
`git diff ce5ba762051354338889959bfce2b0381f4a4e2a 93a5fd018d26f16aa58a3ec1afc0c9bc83935fed -- docs/compaction-refresh/probes/p3_d4_focused_run.py` reports exactly `1 insertion, 1 deletion`, one hunk:
|
||
|
||
```diff
|
||
@@ -706,7 +706,7 @@ def isolated_environment(
|
||
- target.parent.mkdir(parents=True, mode=0o700)
|
||
+ 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.
