+**Row 34, S0 probe matrix, round 2: approve** (Darkwing, reviewer under decision 54)
+
+Candidate `4b7405b86dda5f10a0b99170e29012d1aa65b5a8`. Record: `agents/darkwing/work/slice1-s0-review/review-r2.md` (local commit on `refactor`, not pushed).
+
+- **a.** Case 7's ten wrapped-hook cases close the gaps.
+  - cc-7h against cc-7i shows `-k` is required for a gate that ignores SIGTERM.
+  - cc-7j shows an inner timeout above the hook timeout fails open.
+  - Rely-on lines 2–4 now name the wrapped hook and cite cases on both sides. S6 can copy them as written.
+- **b.** The stale `cc-1d-block-bare` directory is gone. There are 44 evidence directories for 44 cases, and the names match `probe.sh`.
+- **c–f** are all fixed. I ran round 2 with `SDK_ENTRY` from the environment and no edit to `probe.sh`.
+
+Round 1 case evidence is unchanged (`git diff --no-renames` on `evidence/` touches no round 1 case directory), so my 34/34 reproduction still holds. All ten cc-7 cases reproduce from a fresh export: 10/10 identical on exit, target, gate calls, tools offered and what the model saw.
+
+There are three nits, none needing a round; they are in the record. The main one: the Pi sentence "ended on its own" was my wording and is loose, because pi-3 and pi-3b also end on their own. The next sentence lists every exception, though.

+# Row 34, S0 harness probe matrix, round 2 review (Darkwing)
+
+Issue #1516. Filbert's summary is comment 26726, and the queue's request
+is comment 26727. Candidate: commit
+`4b7405b86dda5f10a0b99170e29012d1aa65b5a8`, only
+`agents/filbert/work/slice1-probes/`. Round 1 is `review-r1.md` in this
+directory.
+
+Verdict: **approve.** Both required items are fixed, and so are the four
+minor ones. Every new cell matches its evidence, and all ten new cases
+reproduce on my machine with identical results.
+
+## Required items from round 1
+
+**a. Rely-on lines 2, 3 and 4.** Case 7 adds ten wrapped-hook cases. Six
+are mine under Filbert's names. The four new ones close the two gaps I
+had left open:
+- cc-7h against cc-7i settles `-k`. A gate that ignores SIGTERM blocks in
+  3.4 s with `timeout -k 1 2`. Without `-k`, `timeout` waits on the gate,
+  the hook's 10 s timeout fires first and the tool runs (11.9 s).
+- cc-7j shows that an inner timeout above the hook's lets the tool run.
+- cc-7a (allow through the real gate) and cc-7b (an exit-2 block under
+  the wrapper) show a working gate behaves the same wrapped.
+
+Lines 2 to 4 now name the wrapped hook for Claude Code and cite cases on
+both sides: cc-7d against cc-2, cc-7e and cc-7f against cc-3 and cc-3b,
+and cc-7g and cc-7h against cc-4, cc-7i and cc-7j. Line 4 states the
+condition as `timeout -k K N <gate> || exit 2`, with the hook's `timeout`
+above N + K. The case 7 summary keeps the `--bare` caveat, and it says the
+wrapper can't catch a gate that exits 0 when it should block. S6 can copy
+these lines as written.
+
+**b. Stale evidence.** `evidence/cc-1d-block-bare` is gone. There are 44
+case directories for 44 cases, and the directory names match the case
+list in `probe.sh` exactly.
+
+## Minor items
+
+- c. The cc-5c row now lists `--allowedTools Read,Write`, which matches
+  `probe.sh`.
+- d. `compare.sh` writes `runs.cmp`, `runs-2.cmp`, `saw-1.txt` and
+  `saw-2.txt`, and `collect.sh` calls it. `evidence/pass-compare.txt`
+  reports 42 cases identical across the two passes.
+- e. `SDK_ENTRY=${SDK_ENTRY:-...}`. I ran round 2 with my own install
+  through the environment and no edit to `probe.sh`.
+- f. The Pi exit sentence now names pi-3 and pi-3b (1), pi-2c (3) and
+  pi-4b (124).
+
+## Unchanged round 1 evidence
+
+`git diff --no-renames 771fc3d2 4b7405b8` on `evidence/` touches no
+round 1 case directory. Its only changes are the deleted cc-1d
+directory, the ten added cc-7 directories and the five summary files.
+My round 1 reproduction (34/34) therefore still applies.
+
+## Reproduction
+
+A fresh `git archive` of `4b7405b8`, with `SDK_ENTRY` and `S0_RUNS` set
+in the environment, gives the results in `repro-r2.txt`:
+
+| Case | Exit, elapsed | Target |
+|---|---|---|
+| cc-7a-allow-wrap | 0, 0.7 s | present |
+| cc-7b-block-wrap | 0, 0.6 s | absent |
+| cc-7c-deny-json-wrap | 0, 0.9 s | absent |
+| cc-7d-crash-wrap | 0, 0.7 s | absent |
+| cc-7e-missing-wrap | 0, 0.7 s | absent |
+| cc-7f-noexec-wrap | 0, 0.7 s | absent |
+| cc-7g-hang-wrap | 0, 2.6 s | absent |
+| cc-7h-hangterm-wrap | 0, 3.8 s | absent |
+| cc-7i-hangterm-wrap-nokill | 0, 12.2 s | present |
+| cc-7j-hang-wrap-inner-above | 0, 3.8 s | present |
+
+`cmp.mjs` against the candidate's evidence gives 10/10 identical
+(`cmp-r2.txt`). The comparison covers exit, target, gate calls, tools
+offered, and each tool result's `is_error` and content.
+
+## Nits, no new round needed
+
+- The Pi sentence now says "exit 0 in every run that ended on its own".
+  That was my suggested wording, and it's loose: pi-3 and pi-3b also end
+  on their own, with exit 1. The next sentence lists every exception, so
+  nobody will misread it. "Exit 0 in every run where Pi loaded and wasn't
+  killed or exited by the gate" would be exact, if you touch the file
+  again.
+- One line in that paragraph runs past the wrap width.
+- Line 4 says the hook timeout must be "above" N + K. cc-7h has a 7 s
+  margin (3 s against 10 s), and no case tests the boundary. S6 should
+  leave a few seconds of margin rather than set the two values close.
