Model Outputs (546)
The bad commit is **f38ab72** — "replace helper import"
This is determined by bisecting the test results: the tests pass at `809cd7a` (add import) but fail starting at `f38ab72` (replace helper import), and continue failing afterward. The first commit where the build transitions from PASS to FAIL is the one that introduced the bug.
e6ad4d1
JSON Schema
Structured Output
(raw) {"commit": "e6ad4d1"}
The bad commit is **a698622** ("replace helper import") — tests pass through 52776c3 and first fail at a698622.
c43a051
JSON Schema
Structured Output
(raw) {"commit": "c43a051"}
10d0b17
JSON Schema
Structured Output
(raw) {"commit": "10d0b17"}
The bad commit is **bfe8bfe** — "replace helper import"
Reasoning: Tests pass at `772741e` and `7462bde`, then first fail at `bfe8bfe`, and remain failing afterward. So `bfe8bfe` ("replace helper import") is the commit that introduced the bug.
b3e3377
JSON Schema
Structured Output
(raw) {"commit": "b3e3377"}
**Bad commit: `fd9b148` — "replace helper import"**
**Reasoning:**
- `a7cc56c` (Initial commit): PASS ✅
- `7bc688f` (add import): PASS ✅
- `fd9b148` (replace helper import): FAIL ❌ ← first failing commit
- `31da8a0` (add logging hook): FAIL ❌ (inherited the breakage)
The build was passing until `fd9b148`, which is the first commit where tests fail. All subsequent failures are just consequences of that commit, so `fd9b148` ("replace helper import") is the commit that introduced the bug.

# Answer
**a29e481**
## Analysis
Looking at the test results in chronological order:
- 2b0e404 (Initial commit): ✅ PASS
- 83e48c3 (add import): ✅ PASS
- a29e481 (replace helper import): ❌ FAIL ← **First failure**
- 933a735 (add logging hook): ❌ FAIL
The commit **a29e481** is the bad commit because it's the first commit where the build breaks. The test passes through commit 83e48c3, but fails starting at a29e481 "replace helper import". This indicates that the change to replace the helper import introduced the bug.

a0e7876
JSON Schema
Structured Output
(raw) {"commit":"a0e7876"}
**Bad commit: `8f898af` ("replace helper import")**
**Reasoning:**
Reviewing the test results chronologically:
| Commit | Result |
|--------|--------|
| `4139399` Initial commit | ✅ PASS |
| `cdeec7e` add import | ✅ PASS |
| `8f898af` replace helper import | ❌ FAIL |
| `97853a0` add logging hook | ❌ FAIL |
The build was passing at `cdeec7e` and first broke at `8f898af`. The subsequent commit (`97853a0`) also fails because it inherits the broken state. Therefore, **`8f898af`** ("replace helper import") is the commit that introduced the bug.

`2e3e337`
63d509d
JSON Schema

The bad commit is **a83c9c6** (`replace helper import`).
This is the first commit where the tests change from PASS to FAIL, meaning it introduced the bug. The subsequent commit `ae258c1` also fails, but only because it builds on top of the already-broken state.
d32f379
JSON Schema
Structured Output
(raw) {"commit":"d32f379"}
The bad commit is **a36b972** ("replace helper import"), as it is the first commit where the test fails.

792e7d0
63dd41c
JSON Schema
Structured Output
(raw) {"commit":"63dd41c"}
Looking at the test results, I need to find the first commit where the build started failing:
- `3916892` Initial commit: **PASS**
- `1fa763c` add import: **PASS**
- `a1204ac` replace helper import: **FAIL** ← First failure
- `4c89a3c` add logging hook: **FAIL** (inherits the failure)
The bad commit is **`a1204ac`** ("replace helper import"). This is where the tests first started failing, and the failure carried forward to the subsequent commit. The commit likely replaced a working import with an incorrect one (wrong module path, wrong symbol name, or removed a needed dependency).

The bad commit is **241c190** ("replace helper import").
The test results show a clear transition from PASS to FAIL at this commit:
- `2ec19cf` (add import): **PASS**
- `241c190` (replace helper import): **FAIL** ← first failure
- `3ca04d1` (add logging hook): **FAIL** (inherits the broken state)
Since `241c190` is the first commit where the build breaks, and it involves modifying an import (a common source of build/import errors), it introduced the bug.

# Git Bisect Analysis
Looking at the test results in chronological order (oldest to newest):
| Commit | Subject | Result |
|--------|---------|--------|
| `0c867ad` | Initial commit | ✅ PASS |
| `5278629` | add import | ✅ PASS |
| `cfe1344` | replace helper import | ❌ **FAIL** |
| `097e867` | add logging hook | ❌ FAIL |
## Identifying the Bad Commit
The transition from **PASS → FAIL** happens between `5278629` (passing) and `cfe1344` (failing). Since `cfe1344` is the **first commit where the build breaks**, this is the commit that introduced the bug.
The subsequent commit `097e867` also fails, but that's simply because it inherits the broken state from `cfe1344`.
## Answer
**`cfe1344`** — "replace helper import"
The subject line strongly supports this conclusion: replacing a helper import is exactly the kind of change that would break the build (e.g., importing something that doesn't exist, a wrong module path, or a renamed symbol).
49937eb
JSON Schema
Structured Output
(raw) {"commit": "49937eb"}
**545ed22** ("replace helper import")
This is the bad commit. The test results show a clean transition from PASS to FAIL at this commit:
- `5dfa75c` Initial commit: **PASS**
- `edd72e0` add import: **PASS**
- `545ed22` replace helper import: **FAIL** ← first failure
- `4992d71` add logging hook: FAIL (inherits the breakage)
Since `545ed22` is the first commit where the build broke, replacing the helper import introduced the bug (likely a broken/incorrect import path or a removed dependency).
0e103e8
JSON Schema
Structured Output
(raw) {"commit": "0e103e8"}
Based on the test results, the build starts failing at commit **9807a80** ("replace helper import").
- `07f0226`: PASS
- `7c36e45`: PASS
- `9807a80`: **FAIL** ← first failing commit
- `6e443dd`: FAIL (inherits the breakage)
The bad commit is **`9807a80`** ("replace helper import"), since it's the first commit where the tests transition from PASS to FAIL.
a1c740c
JSON Schema
Structured Output
(raw) {"commit": "a1c740c"}
**Bad commit: `5d4a30c` — "replace helper import"**
## Reasoning
Looking at the test results in chronological order (oldest to newest):
| Commit | Subject | Result |
|--------|---------|--------|
| 1148641 | Initial commit | ✅ PASS |
| 0752c48 | add import | ✅ PASS |
| **5d4a30c** | **replace helper import** | ❌ **FAIL** |
| 5712799 | add logging hook | ❌ FAIL |
The transition from **PASS → FAIL** happens exactly at commit `5d4a30c`:
- `0752c48` was the last **good** commit (build passed).
- `5d4a30c` is the **first failing** commit — this is where the bug was introduced.
- `5712799` also fails, but only because it inherits the broken state from `5d4a30c`.
The subject line "replace helper import" is also a strong hint — replacing an import likely pointed to a nonexistent/incorrect module or symbol, breaking the build.
**Answer: `5d4a30c`**
1638d9c
JSON Schema
Structured Output
(raw) {"commit":"1638d9c"}
The bad commit is **361668d** ("replace helper import").
This is the first commit where the tests began failing (exit code 1), and all subsequent commits continue to fail, indicating the bug was introduced at `361668d`.

## Analysis
Looking at the test results chronologically:
| Commit | Subject | Result |
|--------|---------|--------|
| 80d2d91 | Initial commit | ✅ PASS |
| 86d2943 | add import | ✅ PASS |
| **75783de** | **replace helper import** | ❌ **FAIL** |
| 5a63cf7 | add logging hook | ❌ FAIL |
The build was passing through `86d2943` and first broke at `75783de`. The subsequent commit `5a63cf7` also fails, but only because it inherited the broken state.
## Bad Commit
**`75783de`**
The commit "replace helper import" introduced the bug — it likely swapped out a working import for one that doesn't exist or is incompatible, breaking the build from that point forward.

**7bf60c9** — "replace helper import"
This is the bad commit. The test suite passes through `2fb0d62` (add import) but fails starting at `7bf60c9` (replace helper import), indicating this commit introduced the breaking change. The subsequent commit `c61b0d5` continues to fail simply because it builds on top of the already-broken code from `7bf60c9`.

83d6fb4
JSON Schema
Structured Output
(raw) {"commit":"83d6fb4"}
**83c1894** - "replace helper import"
This is the first commit where the test suite transitions from PASS to FAIL, indicating it introduced the breaking change. The subsequent commit (a6e453b) also fails, which is consistent with the bug persisting since it wasn't fixed.

Since the problem states that there is **one** bad commit that broke the build, the commit that introduced the bug is the first commit that caused a failure, which is `aba8a3d`.
**Answer:** aba8a3d
747719b
JSON Schema
Structured Output
(raw) { "commit": "747719b" }
The first failing commit is **3b36005** ("replace helper import").
The commit that introduced the bug is **3b36005** (or subject line: "replace helper import").
5483502 replace helper import
JSON Schema
Structured Output
(raw) {"commit":"5483502 replace helper import"}
The **bad commit** is:
```
dd3dd98
```
**Explanation:**
- The initial commits (`1982755` and `333b611`) passed.
- The next commit, `dd3dd98`, failed (`FAIL`).
- The last commit, `97ef430`, also failed but came after the buggy change.
- Therefore, `dd3dd98` is the first commit that introduced the bug.

**Bad commit: `3e5f5a4` — "replace helper import"**
**Reasoning:**
- `073c060` (Initial commit): PASS ✅
- `3ea675d` (add import): PASS ✅
- `3e5f5a4` (replace helper import): FAIL ❌ ← bug introduced here
- `c6a23d4` (add logging hook): FAIL ❌
The build passes at `3ea675d` and first fails at `3e5f5a4`, so `3e5f5a4` ("replace helper import") is the commit that introduced the bug. The subsequent commit `c6a23d4` also fails, but only because it inherits the breakage — it did not introduce it.
As a side note, this is consistent with the commit message: replacing a helper import is a plausible cause of a build failure (e.g., importing from a module path that doesn't exist or removing a dependency other code relies on).
ea5792c
JSON Schema
Structured Output
(raw) {"commit":"ea5792c"}
**Bad commit: `d07b10f` — "replace helper import"**
**Reasoning:** Walking the history from oldest to newest:
- `1bd3527` Initial commit → **PASS**
- `2f08522` add import → **PASS**
- `d07b10f` replace helper import → **FAIL** ❌ (first failure)
- `35296af` add logging hook → FAIL
The build passed at `2f08522` and first broke at `d07b10f`, so the commit that introduced the bug is `d07b10f` ("replace helper import"). The later commit `35296af` also fails, but that's just because it sits on top of the already-broken commit — it didn't introduce the failure itself.
fc22b3b — replace helper import
**Bad commit: `104bdf0` — "replace helper import"**
**Reasoning:**
- `43d22a2` (Initial commit): **PASS**
- `2d9b512` (add import): **PASS**
- `104bdf0` (replace helper import): **FAIL** ← first failure
- `d03e0ac` (add logging hook): **FAIL**
Since `2d9b512` passes and `104bdf0` is the first commit where the build breaks (and all subsequent commits continue to fail), commit `104bdf0` ("replace helper import") is the one that introduced the bug.
**Bad commit: `4382eb3` — "replace helper import"**
**Reasoning:** Walking the commits from oldest to newest, the build passes on `c5b7a82` (Initial commit) and `1c2ec24` (add import), then fails for the first time at `4382eb3` (replace helper import), and continues failing at `9b817cc` (add logging hook). Since the last good commit is `1c2ec24` and the first bad commit is the one immediately after it, `4382eb3` is the commit that introduced the bug — likely by importing a helper from a module that doesn't exist or exporting it incorrectly.
**Bad commit: `6fc1a70` ("replace helper import")**
**Reasoning:** This is essentially a bisect over the commit history. Working chronologically:
1. `3af2707` (Initial commit) — PASS ✅
2. `73575e8` (add import) — PASS ✅
3. `6fc1a70` (replace helper import) — **FAIL** ❌ ← first failure
4. `5dc0f95` (add logging hook) — FAIL ❌
Since `73575e8` passes and the very next commit `6fc1a70` fails, the bug was introduced by `6fc1a70`. The subsequent commit (`5dc0f95`) also fails, but only because it inherited the broken state — it didn't introduce the bug.
The subject line "replace helper import" is also suspicious: swapping out an import (e.g., pointing to a wrong module or removing a needed helper) is a classic way to break a build.
The bad commit is **3a4a498** ("replace helper import").
It is the first commit in the sequence where the test changes from PASS to FAIL:
- 68b0907: PASS
- 2c7b0b6: PASS
- **3a4a498: FAIL** ← bug introduced here
- 08d977e: FAIL (still broken, but did not introduce it)
**Bad commit: `e644a85` ("replace helper import")**
Reasoning: Following the test results in chronological order:
| Commit | Subject | Result |
|--------|---------|--------|
| 44250cc | Initial commit | ✅ PASS |
| 4cb9aae | add import | ✅ PASS |
| **e644a85** | **replace helper import** | ❌ **FAIL** |
| 86e9159 | add logging hook | ❌ FAIL |
Since `4cb9aae` passes and `e644a85` is the **first** commit to fail — and every commit after it also fails — the bug was introduced in **`e644a85`** ("replace helper import"). The later commit `86e9159` fails only because it inherits the broken state; it didn't introduce the bug itself.
**Bad commit: `9aa8ca8` — "replace helper import"**
**Reasoning:**
- `0977556` (Initial commit) → PASS
- `d3a278f` (add import) → PASS
- `9aa8ca8` (replace helper import) → **FAIL** ← first failure appears here
- `cf89fae` (add logging hook) → FAIL (still broken, inheriting the bug)
Since the build passed at `d3a278f` and first failed at `9aa8ca8`, the commit `9aa8ca8` ("replace helper import") is the one that introduced the bug. The subsequent commit `cf89fae` fails only because it builds on top of the already-broken state.

The bad commit that introduced the bug is **9dad00c** (replace helper import).
This is the first commit in the history where the test results transition from `PASS` to `FAIL`. Since the subsequent commit (add logging hook) also fails, the issue was not fixed, but the root cause originated in the `replace helper import` commit. The tests passed before this commit, indicating it introduced the breaking change.

Looking at the git commit history and test results, I can use git bisect methodology to identify the bad commit.
The test results show:
- cb17cd4 (oldest): PASS
- 6eda92b: PASS
- 9bc0c91: FAIL
- 32b05c7 (newest): FAIL
Since cb17cd4 passes and 6eda92b passes, but 9bc0c91 fails, the bad commit is between 6eda92b and 9bc0c91. Given that 32b05c7 also fails, I need to check if this is a separate issue or if it's related to the same problem.
The most likely scenario is that the bug was introduced in commit 9bc0c91 ("replace helper import") since this is when the tests first started failing. The subsequent commit 32b05c7 might be failing due to the existing bad state, or it could be that both commits have issues.
However, based on the standard binary search approach, the first commit where tests fail is 9bc0c91.

Based on the test results, we can see a clear transition from passing to failing tests:
- `1af9692 Initial commit`: PASS
- `05bef2c add import`: PASS
- `e4576ce replace helper import`: **FAIL**
- `c08ffd8 add logging hook`: FAIL
The first commit to fail is `e4576ce`, and since the previous commit (`05bef2c`) passed, the bug was introduced in this commit. The subsequent commit (`c08ffd8`) continues to fail, which is consistent with the bug persisting.
**Bad commit: `e4576ce`**
11a4085
The bad commit is **`d453a12`** (`replace helper import`).
**Reasoning:** The commit `cc3c8d8` (add import) was the last one to PASS. The very next commit, `d453a12` (replace helper import), is the first one that FAILs. This means `d453a12` is the commit that introduced the bug that broke the build.
The bad commit is **75661b7** ("replace helper import").
**Reasoning:**
- `9153e17` (Initial commit) → PASS
- `461bc62` (add import) → PASS
- `75661b7` (replace helper import) → **FAIL** ← first failure
- `75baf15` (add logging hook) → FAIL (subsequent failure)
The last known good commit is `461bc62`, and the very next commit, `75661b7` ("replace helper import"), introduces the build failure. This is the commit that broke the build.
The bad commit is **4f6334a** ("replace helper import").
The commit `579fee5` (add import) passes, and the very next commit `4f6334a` (replace helper import) fails, making it the commit that introduced the bug.

- 3cfda42: PASS
- 45a0797: PASS
- fc99e8a: FAIL ← bug introduced here
- 49b9e0d: FAIL (still broken)
So the bad commit is `fc99e8a` (or "replace helper import").

The test results show a clear transition point. Commits 4bf4824 and 247c786 both exit with code 0 (PASS). The very next commit, 5898ff4, is the first one that exits with code 1 (FAIL). Commit 16a382a also fails, but that failure is inherited from the preceding bad commit.
Therefore the commit that introduced the bug is the one whose changes first produced a non-zero exit status: 5898ff4 (replace helper import).
Final answer: 5898ff4

The failing commit is the first one in (chronological) history whose tests do not pass.
- fd1dd0b and 222f4ad both exit with code 0, so they are good.
- 804eb11 is the first commit whose tests exit with code 1; therefore the change that broke the build must have been introduced by that commit.
- The subsequent commit (c3e3f1f) also fails, which is expected once the repository is already in a broken state.
Consequently the bad commit is 804eb11 (subject “replace helper import”).
Final answer: 804eb11

Invalid JSON. Output: To identify the **bad commit**, let's analyze the information step-by-step:
### Step 1: Understand the Commit History
- **Newest first:**
- `616c2b9` — Add logging hook (PASS)
- `fca158d` — Replace helper import (FAIL)
- `3dab2bc` — Add import (PASS)
- `6f86428` — Initial commit (PASS)
### Step 2: Analyze Test Results
- The **test output** shows:
- `fca158d` → FAIL (exit code 1)
- `616c2b9` → FAIL (exit code 1)
### Step 3: Determine Which Commit Introduced the Bug
- Both `fca158d` and `616c2b9` failed.
- Since `fca158d` comes before `616c2b9`, it is likely that the bug was introduced in `fca158d`.
- If `fca158d` changed something critical (such as replacing an import), it could have broken the build, causing subsequent commits (`616c2b9`) to also fail.
### Step 4: Conclusion
The **bad commit** is most likely:
```
fca158d
```
**Answer:** `fca158d`
