Model Outputs (546)
**Bad commit: `09c1033` — "disable feature"**
Reasoning:
- `79242f4` (Initial commit): PASS ✅
- `02e6cb9` (enable feature): PASS ✅
- `09c1033` (disable feature): FAIL ❌ ← first failing commit
- `24da4cd` (add feature telemetry): FAIL ❌ (inherited breakage)
The build was passing until `09c1033` "disable feature", which is the first commit where tests fail. All subsequent failures stem from it, making it the commit that introduced the bug.
4e528fd
JSON Schema
Structured Output
(raw) {"commit": "4e528fd"}
bc59762 — "disable feature" is the bad commit (first failing commit; tests passed through 21f3d45 and failed from bc59762 onward).
31a934e
JSON Schema
Structured Output
(raw) {"commit": "31a934e"}
**Bad commit: `c5772f3` — "disable feature"**
**Reasoning (bisect logic):**
| Commit | Subject | Result |
|--------|---------|--------|
| f63522a | Initial commit | ✅ PASS |
| 2b48bd7 | enable feature | ✅ PASS |
| c5772f3 | disable feature | ❌ FAIL ← first bad commit |
| 8c2668a | add feature telemetry | ❌ FAIL |
The tests pass through `2b48bd7` and first fail at `c5772f3`. Since `c5772f3` is the transition point from PASS → FAIL, it introduced the bug. The subsequent commit (`8c2668a`) fails only because it's built on top of the broken state.
6b276b9
JSON Schema
Structured Output
(raw) {"commit": "6b276b9"}
The bad commit is **c9c269a** — "disable feature".
Reasoning: Tests pass through `139ad44` (enable feature) but first fail at `c9c269a` (disable feature), and every commit after it continues to fail. The first failing commit in the history is the one that introduced the bug.
66756ff
JSON Schema
Structured Output
(raw) {"commit": "66756ff"}
The bad commit is **3dc4745** — "disable feature"
**Reasoning:**
- `a6bd22a` (Initial commit): PASS ✅
- `0d37d69` (enable feature): PASS ✅
- `3dc4745` (disable feature): FAIL ❌ ← first failing commit
- `525c905` (add feature telemetry): FAIL ❌ (inherited the breakage)
The transition from PASS to FAIL occurred at commit `3dc4745` ("disable feature"), making it the commit that introduced the bug. The subsequent commit fails only because it was built on top of the already-broken state.

1. **8752e4c** (Initial commit): ✅ PASS
2. **008702f** (enable feature): ✅ PASS
3. **cc66540** (disable feature): ❌ **FAIL** ← First failure
4. **65db730** (add feature telemetry): ❌ FAIL
The build was passing through the "enable feature" commit, but failed starting with "disable feature". The subsequent commit remains broken as well, indicating it didn't fix the issue introduced by "disable feature".
**Answer: cc66540** (or "disable feature")

# Analysis
Looking at the test results in chronological order:
1. **d71d259** (Initial commit): ✅ PASS
2. **5da338a** (enable feature): ✅ PASS
3. **730e3e4** (disable feature): ❌ FAIL
4. **286c20b** (add feature telemetry): ❌ FAIL
The first commit where the tests fail is **730e3e4**.
## Answer
**730e3e4** (or "disable feature")
This is the bad commit that broke the build. The feature worked fine when enabled in commit 5da338a, but broke when disabled in commit 730e3e4.
0a48933

**Bad commit: `5859697` (disable feature)**
**Reasoning:** Looking at the test results in chronological order:
| Commit | Result |
|--------|--------|
| 772f79a Initial commit | ✅ PASS |
| a22ae60 enable feature | ✅ PASS |
| **5859697 disable feature** | **❌ FAIL** |
| 399ce10 add feature telemetry | ❌ FAIL |
The build was passing through `a22ae60`, and the first failure appeared at `5859697`. The subsequent commit (`399ce10`) also fails because it inherits the broken state. Therefore, `5859697` is the commit that introduced the bug.

- `197f293` enable feature: PASS
- `0eaa74d` disable feature: **FAIL** ← First failing commit
- `8e2b6d5` add feature telemetry: FAIL
The bad commit is **`0eaa74d`** ("disable feature").
This is the first commit where the tests started failing. The commit before it (`197f293`) passed, but immediately after `0eaa74d` was applied, the build broke and remained broken in subsequent commits.

## Analysis
Looking at the test results in chronological order (oldest to newest):
| Commit | Subject | Result |
|--------|---------|--------|
| ba13a1b | Initial commit | ✅ PASS |
| 7f5d8e4 | enable feature | ✅ PASS |
| **4e2fd68** | **disable feature** | ❌ **FAIL** |
| 58f2955 | add feature telemetry | ❌ FAIL |
The transition from **PASS → FAIL** occurs at commit `4e2fd68`. This is the first commit where the build breaks, and all subsequent commits inherit the failure.
## Answer
**`4e2fd68`** ("disable feature")
This is the bad commit that introduced the bug. The preceding commit (`7f5d8e4`) still passes, and everything after `4e2fd68` fails—confirming this is where the regression was introduced. The later failure in `58f2955` is just a downstream consequence of the broken state, not a separate bug.
0fe39d1
JSON Schema
Structured Output
(raw) {"commit": "0fe39d1"}
**5979d5b** ("disable feature")
This is the bad commit. The test results show a clear transition point:
- `e36ce58` (enable feature): **PASS**
- `5979d5b` (disable feature): **FAIL** ← first failure
Since `5979d5b` is the first commit where the build breaks (and all subsequent commits remain broken), it's the commit that introduced the bug.
48f5906
JSON Schema
Structured Output
(raw) {"commit": "48f5906"}
The bad commit is **2d403c2** ("disable feature").
The test transitions from PASS to FAIL at commit `2d403c2` — the last passing commit is `ca11029` and the first failing commit is `2d403c2`, which introduced the bug.
4b22d10
JSON Schema
Structured Output
(raw) {"commit": "4b22d10"}
**Bad commit: `495b356` ("disable feature")**
**Reasoning:**
Looking at the test results in chronological order (oldest first):
| Commit | Subject | Result |
|--------|---------|--------|
| b9bbe1e | Initial commit | ✅ PASS |
| ba0cb35 | enable feature | ✅ PASS |
| **495b356** | **disable feature** | ❌ **FAIL** |
| a321b86 | add feature telemetry | ❌ FAIL |
The transition from PASS → FAIL happens at commit `495b356` ("disable feature"). Everything before it passes, and everything from that point onward fails. This is the first bad commit that introduced the breakage.
The subsequent commit `a321b86` also fails, but only because it inherits the broken state from `495b356` — it did not introduce the bug itself.
c30510f
JSON Schema
Structured Output
(raw) {"commit": "c30510f"}
The bad commit is **87dc9bf** ("disable feature").
This is the first commit where the test fails (exit code 1), while the previous commit `0368448` still passed. The subsequent commit `1628862` also fails, but it inherited the broken state introduced by `87dc9bf`.

## Analysis
Looking at the test results ordered from oldest to newest:
| Commit | Message | Result |
|--------|---------|--------|
| `18f3af9` | Initial commit | ✅ PASS |
| `9188ccd` | enable feature | ✅ PASS |
| `de835d8` | disable feature | ❌ FAIL |
| `56ce0b1` | add feature telemetry | ❌ FAIL |
The build transitions from **PASS → FAIL** at commit `de835d8`. All subsequent commits also fail, which is consistent with an unresolved bug introduced at this point.
## Answer
**`de835d8`** ("disable feature")
This is the commit that introduced the bug — the build was passing before it and has been failing since.
b936d75
JSON Schema

(raw) {"commit":"b936d75"}
The bad commit is `861c82a`.
5ab8f9f
JSON Schema
Structured Output
(raw) {"commit":"5ab8f9f"}
The bad commit is **89266c3** (disable feature).
**Reasoning:**
- `873563d` (Initial commit): PASS
- `15529f9` (enable feature): PASS
- `89266c3` (disable feature): FAIL ← first failing commit
- `89fdb59` (add feature telemetry): FAIL (inherited broken state)
The bug was introduced in commit `89266c3` ("disable feature"), as it is the first commit where the tests went from PASS to FAIL.
281c654
JSON Schema
Structured Output
(raw) {"commit":"281c654"}
Based on the test results, the build was passing up through commit `a7c5a71` (enable feature) and first started failing at commit `17b5947` (disable feature).
The bad commit is: **17b5947**

96e6d77
JSON Schema
Structured Output
(raw) {"commit": "96e6d77"}
**949452e - "disable feature"**
This is the first commit where the build fails (exit code 1), transitioning from a passing state at `517daf3`. Since `713a415` continues to fail, the bug was introduced in `949452e` and persists afterward.
3f3c223
JSON Schema
Structured Output
(raw) {"commit":"3f3c223"}
**a70235f** (disable feature)
This is the first commit where the tests start failing (exit code 1), while the parent commit `3a4f67e` still passed. Since `d8ddcb9` also fails, it's likely just inheriting the break introduced by `a70235f` rather than causing a new one. The bisection points to `a70235f` as the commit that introduced the bug.
6e36d4b
JSON Schema
Structured Output
(raw) {"commit": "6e36d4b"}
**5f6046b** (disable feature)
This is the first commit where the build fails — it passed at `415e46c` and failed starting at `5f6046b`, so this commit introduced the bug. The subsequent failure at `2735e43` is just a continuation of the broken state.
380ea05
JSON Schema
Structured Output
(raw) {"commit":"380ea05"}
**14faf4d - "disable feature"**
This is the first commit where the tests transition from PASS to FAIL. Since `1d93b71` (enable feature) passed, but `14faf4d` (disable feature) failed, this commit introduced the bug that broke the build. The subsequent commit `f4ffd0b` still fails, which is consistent with the bug persisting rather than being introduced again.
eb63df2
JSON Schema
Structured Output
(raw) {"commit":"eb63df2"}
The bad commit is the one that first caused the test to fail, which is the commit with hash `b2cd4cf` (subject line: "disable feature"). This is evident because the test passes for the initial commit and the "enable feature" commit, but fails for the "disable feature" commit and remains failing for the subsequent "add feature telemetry" commit. The failure was introduced by the "disable feature" commit.
**Answer:** b2cd4cf
The first commit where the tests fail is `02a0b4a` ("disable feature"). This is the commit that introduced the bug.
Answer: `02a0b4a`
5810ec1
24baf04
3fa113e
6ec32d8
**Reasoning:**
1. **Test Results Order:** The test results are listed from oldest commit (fc80e19) to newest (ba0fb55).
2. **First Failure:** The first commit to fail its test is `6ec32d8` (disable feature) with exit code 1.
3. **Subsequent Failure:** The next commit (`ba0fb55` - add feature telemetry) also fails.
4. **Single Bad Commit:** The problem states there is *one* bad commit that broke the build. The failure starting at `6ec32d8` is the first indication of a problem. The failure of `ba0fb55` is likely a consequence of the bug introduced in `6ec32d8` not being fixed, but the root cause is `6ec32d8`.
5. **Conclusion:** The commit that introduced the bug causing the build to break is `6ec32d8`.

The bad commit is the one that introduced the failure in the latest failing test, which is **commit 455b7e9** with the subject "add feature telemetry". However, the test results also show that the previous commit **38d8a62** ("disable feature") also failed, indicating that the most recent change (455b7e9) likely built upon an existing issue introduced by 38d8a62. Since the question asks for the commit that "broke the build," the immediate bad commit based on the failing test is **455b7e9**.
**Answer:** `455b7e9`
d09725d
JSON Schema
Structured Output
(raw) { "commit": "d09725d" }
The first failing commit is **787dc1e** ("disable feature").
Test results show:
- 993a335 (Initial commit): PASS
- b92c2df (enable feature): PASS
- 787dc1e (disable feature): FAIL ← first failure
- c55d81d (add feature telemetry): also FAIL, but introduced after the first bad commit
Therefore, the bad commit that introduced the bug is **787dc1e**.

Let's analyze step-by-step:
### Step 1: Understand the scenario
- There is **one bad commit** that broke the build.
- Builds fail (`FAIL` exit code) for two commits:
- `9b3213d` (disable feature)
- `1706e32` (add feature telemetry)
- Both failed, but only **one** is the "bad" commit.
### Step 2: Consider typical patterns
- Usually, a change that introduces a bug would cause a failure in a subsequent build.
- If both commits failed, it's possible that the **last** one (`1706e32`) caused the failure, especially if it's the most recent.
### Step 3: Check the order of commits
- The list is newest first:
1. `1706e32`
2. `ecd71a0`
3. `dad5c22`
- The last commit (`1706e32`) is the most recent, so if there was a regression, it's likely this one.
### Step 4: Test outputs
- `dad5c22`: PASS
- `ecd71a0`: PASS
- `9b3213d`: FAIL
- `1706e32`: FAIL
So, the **failure at `1706e32`** is the latest commit, and since it's the only one that could have introduced the bug (since `9b3213d` passed), it's most likely the culprit.
---
## Final Answer
**The bad commit is:**
`1706e32`

dda3dd7 (disable feature)
This is the first commit in the history where the tests started failing. The "Initial commit" and "enable feature" commits both passed, so the bug was introduced by the "disable feature" commit. The subsequent "add feature telemetry" commit also fails because it builds on the already-broken state.
70e7bad Initial commit: PASS (exit code 0)

Based on the test results, the build started failing at commit `53bb4c4` (disable feature) and continued to fail in the subsequent commit `8078a79` (add feature telemetry).
The bad commit that introduced the bug is:
`53bb4c4` (or the subject line "disable feature")
542928c
JSON Schema
Structured Output
(raw) {"commit": "542928c"}
The test results show that the build passed at commit `9969d59` and first failed at `b857bc4`. Therefore, the bad commit that introduced the bug is `b857bc4`.

The test results show the build was passing up to commit `436a480` (enable feature) and first failed at commit `87ffb33` (disable feature). Since this is the first commit in the history where the build breaks, it is the bad commit that introduced the bug.
87ffb33
8ad7684
JSON Schema
Structured Output
(raw) {"commit": "8ad7684"}
The bad commit is `3c9ea4b disable feature`.
This is because the tests passed for the initial commit (`5fbfcaf`) and the "enable feature" commit (`eff9858`), but then failed starting with the "disable feature" commit (`3c9ea4b`). The subsequent commit (`d710b50`) also failed, which is expected since the bug was already introduced in `3c9ea4b`. Thus, `3c9ea4b disable feature` is the first bad commit that broke the build.
Answer: `3c9ea4b` (or `disable feature`).

14e5fb8
JSON Schema
Structured Output
(raw) { "commit": "14e5fb8" }
**Bad commit: `1761d29` — "disable feature"**
**Reasoning:**
- `391be9d` (Initial commit): PASS
- `ef6ad52` (enable feature): PASS
- `1761d29` (disable feature): **FAIL** ← first failure
- `2a811af` (add feature telemetry): FAIL
Using a bisect-style analysis, the build passed at `ef6ad52` but failed at its immediate child `1761d29`. Since `1761d29` is the first commit where the test transitions from PASS to FAIL, it is the commit that introduced the bug. The later commit `2a811af` also fails, but it merely inherited the breakage — it didn't cause it.
**Bad commit: `50754b5` — "disable feature"**
**Reasoning:**
- `dad76b4` (Initial commit): PASS
- `1d557d3` (enable feature): PASS — last known good commit
- `50754b5` (disable feature): **FAIL** — first commit where the build breaks
- `c04cb7e` (add feature telemetry): FAIL — still broken, as expected
Since `1d557d3` passes and the very next commit `50754b5` fails, the bug was introduced by **50754b5 ("disable feature")**. All subsequent commits inherit the broken state.
**Bad commit: `f6dd0a5` ("disable feature")**
**Reasoning:**
- `0ffc219` (Initial commit): **PASS** ✅
- `098ec05` (enable feature): **PASS** ✅
- `f6dd0a5` (disable feature): **FAIL** ❌ ← first failing commit
- `f4d1ec0` (add feature telemetry): **FAIL** ❌
The build passed at `098ec05` and first failed at `f6dd0a5`. Since `f6dd0a5` is the transition point from PASS to FAIL, it is the commit that introduced the bug. The subsequent commit (`f4d1ec0`) also fails, but it merely inherited the broken state from `f6dd0a5`.
**Bad commit: `72d45ef` — "disable feature"**
**Reasoning:**
- `2476e94` (Initial commit): PASS
- `a929d39` (enable feature): PASS
- `72d45ef` (disable feature): **FAIL** ← first failure appears here
- `56f55e2` (add feature telemetry): FAIL
Since the build passes at `a929d39` and first fails at `72d45ef`, the commit `72d45ef` ("disable feature") is the one that introduced the bug. The later commit `56f55e2` also fails, but only because it inherits the broken state from `72d45ef`.
**178ceee** — `disable feature`
**Bad commit: `f97279d` — "disable feature"**
**Reasoning:**
- `cd1db62` (Initial commit): PASS
- `549caa5` (enable feature): PASS
- `f97279d` (disable feature): **FAIL** ← first failing commit
- `12cb124` (add feature telemetry): FAIL
Since the build passed at `549caa5` and first failed at `f97279d`, the commit **`f97279d` ("disable feature")** is the one that introduced the bug. The subsequent commit (`12cb124`) also fails because it builds on top of the already-broken state — in a `git bisect`, this is exactly how you'd identify the first bad commit.
**Bad commit: `6042fd5` — "disable feature"**
**Reasoning:**
- `bf61844` (Initial commit): PASS ✅
- `36092e4` (enable feature): PASS ✅
- `6042fd5` (disable feature): **FAIL** ❌ ← first failure appears here
- `5149f23` (add feature telemetry): FAIL ❌ (inherits the breakage)
Since `36092e4` is the last commit where tests pass and `6042fd5` is the first commit where tests fail, the bug was introduced by commit **`6042fd5`** ("disable feature"). The subsequent commit merely inherits the broken state.
The bad commit is **2e72a90** ("disable feature").
It's the first commit where the build changes from PASS to FAIL: the previous commit `486e7a1` passed, while `2e72a90` failed (and the later `2773545` remained failing).
**e905aae** — "disable feature"
The build passes at `fcd0ab0` ("enable feature") and first fails at `e905aae` ("disable feature"), making `e905aae` the commit that introduced the bug. The subsequent commit `626f638` also fails, but it only inherited the broken state.
**Bad commit: `71f6c1c` ("disable feature")**
**Reasoning:**
- `41184c9` (Initial commit): PASS ✅
- `94a4e93` (enable feature): PASS ✅
- `71f6c1c` (disable feature): **FAIL** ❌ ← first failing commit
- `a7ffc1b` (add feature telemetry): FAIL ❌ (inherits the breakage)
The transition from PASS to FAIL occurs between `94a4e93` and `71f6c1c`, so `71f6c1c` ("disable feature") is the commit that introduced the bug. The later commit `a7ffc1b` also fails, but only because the bug was already present in its parent.
In a real workflow, `git bisect` would confirm this: with `94a4e93` as the last good commit and `a7ffc1b` as the first known bad commit, bisection converges on `71f6c1c` as the culprit.

Since the build passes at 004d99c and fails at 87f6a28, the first failure occurs at commit **87f6a28**.
Therefore, the bad commit that introduced the bug is **87f6a28**.

The bad commit that introduced the bug is **89cc449** (subject line: "disable feature").
**Reasoning:**
- The "Initial commit" passes.
- "enable feature" also passes.
- The next commit ("disable feature") causes the first failure.
- Subsequent commits (like "add feature telemetry") continue to fail, indicating the problem was introduced in the earlier "disable feature" commit.
This follows the principle of identifying the **first commit where tests fail**, as later commits inherit the broken state unless fixed.

By analyzing the test results, we see the first failure occurred at this commit. Using git bisect methodology, commits before 38ea930 (d2cfcd3 and 98916c6) passed tests, while commits after (including itself) failed. This indicates 38ea930 introduced the bug. The subsequent commit f3dc87b also fails but does not fix the issue, confirming 38ea930 is the root cause.

- Subsequent commits (e.g., `8232c73`) also fail, but the **first failing commit** is `69c8fa0`.
- This commit introduced a regression that broke the build.
9ce87e8
JSON Schema

The bad commit is identified by the first test failure. The commit "301c58f disable feature" introduced the failure, as the test passed after "491dcd7 enable feature" but failed after "301c58f disable feature". Subsequent failures in later commits (e.g., "9c1cbd7 add feature telemetry") are likely caused by the earlier bad commit, but the root cause is the "disable feature" commit.

- **3beaf4a** disable feature: **FAIL**
- **4efa239** add feature telemetry: **FAIL**
The tests were passing in commit **d2802e4** but failed starting with commit **3beaf4a**. This means commit **3beaf4a** ("disable feature") introduced the bug.

Looking at the test results, I can see when the failure was introduced:
- **c4ac1da** (Initial commit): PASS
- **40e3a2f** (enable feature): PASS
- **caebbb2** (disable feature): FAIL ← First failure
- **67f0df3** (add feature telemetry): FAIL
The tests were passing up until commit `40e3a2f`, but failed starting at `caebbb2`. This means the bug was introduced by commit `caebbb2` with the message "disable feature".
**Bad commit: caebbb2** (or "disable feature")
8fcf83f
JSON Schema
Structured Output
(raw) {"commit": "8fcf83f"}
Looking at the test results, I can see the pattern:
1. `0dac86a Initial commit`: PASS
2. `8b02bfa enable feature`: PASS
3. `29790d4 disable feature`: FAIL
4. `d16aea5 add feature telemetry`: FAIL
The build was passing after `8b02bfa` but failed starting with `29790d4`. This commit has the subject "disable feature" which suggests it's the likely culprit.
The bad commit is: **29790d4**

Looking at the test results:
- 34b450d Initial commit: PASS

- 2297f86 add feature telemetry: FAIL
The tests passed up through commit `81734bd`, but failed starting with commit `32113c5` ("disable feature"). This is the commit that introduced the bug.
**Bad commit: 32113c5**

The bad commit is **4b99661** (or subject line: **disable feature**).
**Reasoning:**
By tracing the test results from oldest to newest, the build passes for `b988370` and `607de60`, but fails immediately in the next commit, `4b99661`. This indicates that commit `4b99661` introduced the regression.

The bad commit is **`2431e81`** (subject: `disable feature`).
This is the first commit in chronological order where the test results changed from `PASS` to `FAIL`, indicating it introduced the regression. All subsequent commits inherit this failure.

The bad commit is **2c5e945** (`disable feature`).
**Reasoning:** Looking at the test results chronologically, the build passed on `c4f348e` (Initial commit) and `88a782a` (enable feature), but then **first failed** on `2c5e945` (disable feature). The subsequent commit `afb4d08` also fails, but it inherited the bug from `2c5e945`. The transition from PASS → FAIL pinpoints `2c5e945` as the commit that introduced the bug.
The bad commit is **6035215** (subject: "disable feature").
**Reasoning:**
Looking at the test results chronologically:
| Commit | Subject | Result |
|--------|---------|--------|
| `4e36590` | Initial commit | ✅ PASS |
| `1442482` | enable feature | ✅ PASS |
| `6035215` | disable feature | ❌ FAIL |
| `1f80e40` | add feature telemetry | ❌ FAIL |
The build was passing up through commit `1442482` and first failed at commit `6035215`. This is the exact commit where the transition from PASS → FAIL occurred, making **`6035215`** the commit that introduced the bug. All subsequent commits (`1f80e40`) continue to fail because they are built on top of the broken state.
Based on the test results, the build was passing at commit `de24e8d` (enable feature) and started failing at commit `a342d3a` (disable feature). Since this is the first commit where the test failed, it is the bad commit that introduced the bug.
**a342d3a**
The bad commit is **f05c58c** (`disable feature`).
The test results show that the build was passing through commit `7e31000` (enable feature) and first failed at commit `f05c58c` (disable feature). This is where the bug was introduced. The subsequent commit `c365f3f` also fails because it inherits the bug from `f05c58c`.
The bad commit is **5faab4e** (disable feature).
The test results show a clear transition: `b16aa26` (enable feature) passed, but the very next commit `5faab4e` (disable feature) failed. This means `5faab4e` is the commit that introduced the bug.
The bad commit that broke the build is **`9029940`** (subject: **"disable feature"**).
The test passed at `d7761ff` (enable feature) and then failed at `9029940` (disable feature), meaning the bug was introduced in commit `9029940`.
The bad commit is **dc26530** ("disable feature").
**Reasoning:** The last good commit is `baaa4fc` (PASS), and the first failing commit is `dc26530` (FAIL). The transition from PASS → FAIL occurs at `dc26530`, making it the commit that broke the build.
35bf48f
The bad commit is **4f971cc** ("disable feature").
The test results show:
- `e0996da` (enable feature): **PASS** ✅
- `4f971cc` (disable feature): **FAIL** ❌
The first failure occurs at commit `4f971cc`, making it the commit that broke the build.

24c3906
The commit history and test results show that builds pass through commit 9535675 but fail starting at 24c3906 (and continue failing afterward). This identifies 24c3906 as the first commit introducing the bug.
a2c6b28
JSON Schema
Structured Output
(raw) {"commit":"a2c6b28"}
The test results show that commit `716c7d4` (the last passing commit) succeeded while the very next commit, `e25f0a7`, was the first to produce a failing exit code. All later commits also fail, but that is simply because they descend from the already-broken state introduced by `e25f0a7`. Consequently the single bad commit is the one whose subject line is “disable feature” (hash `e25f0a7`).
Final answer: e25f0a7

The commit history shows a linear sequence of changes (newest → oldest). The tests pass on the initial commit and after "enable feature", but begin failing starting with the next commit ("disable feature"). That makes 9a9c71e the first failing revision and therefore the commit that introduced the breakage.
Final answer: 9a9c71e

JSON Schema
Structured Output
(raw) {"commit":"e17d1e2"}
