Bad commit changes multiple files (app.py and config.py) - model identifies the multi-file bad commit
Tests ability to identify a multi-file bad commit (app.py + config.py) via bisect. Evaluates bisect for changes spanning multiple files.
Baseline Repository
These commands set up the repo before the model sees the prompt. They define the starting file structure, staged changes, and Git history.

Model Outputs (546)
**Bad commit: `50e1725` — "enable debug mode"**
Reasoning: Walking through the test results in chronological order:
- `7ef3b9e` (Initial commit): PASS
- `3948f0d` (set debug off): PASS
- `50e1725` (enable debug mode): **FAIL** ← first failing commit
- `7a2dbb1` (add startup logging): FAIL (still broken, inherited from previous commit)
The build was passing until `50e1725`, which is the first commit where tests fail. All subsequent commits fail because they build on top of the broken commit. This is exactly how `git bisect` would identify it.
cba9e28
JSON Schema
Structured Output
(raw) {"commit": "cba9e28"}
The bad commit is **3ea1f22** ("enable debug mode") — it's the first commit where tests fail (058daba and 89af953 pass, then 3ea1f22 fails and everything after remains broken).
36ce9ed
JSON Schema
Structured Output
(raw) {"commit": "36ce9ed"}
**Bad commit: `6875a06` — "enable debug mode"**
**Reasoning (bisect-style analysis):**
Walking through the test results chronologically:
| Commit | Subject | Result |
|--------|---------|--------|
| b3b5fe4 | Initial commit | ✅ PASS |
| c3c7e29 | set debug off | ✅ PASS |
| 6875a06 | enable debug mode | ❌ FAIL |
| 3493464 | add startup logging | ❌ FAIL |
The build transitions from **PASS → FAIL** between `c3c7e29` and `6875a06`. Since `6875a06` ("enable debug mode") is the *first* commit where tests fail, it introduced the bug. The subsequent commit `3493464` fails only because it inherits the broken state — it isn't the root cause.
774b746
JSON Schema
Structured Output
(raw) {"commit": "774b746"}
The bad commit is **acccb1b** — "enable debug mode".
Reasoning: Tests pass through `3cef1e6` (set debug off), but the very next commit `acccb1b` (enable debug mode) is the first to fail, and all subsequent commits (`0b1268e`) continue failing. This makes `acccb1b` the commit that introduced the bug.
c7f721f
JSON Schema
Structured Output
(raw) {"commit": "c7f721f"}
**Bad commit: `519f014` — "enable debug mode"**
Reasoning (bisect logic):
- `e130bfd` (Initial commit): PASS ✅
- `4e1e934` (set debug off): PASS ✅
- `519f014` (enable debug mode): FAIL ❌ ← first failing commit
- `3fab881` (add startup logging): FAIL ❌ (inherited breakage)
The build transitioned from passing to failing at commit **519f014**, making it the commit that introduced the bug. The subsequent commit `3fab881` fails only because it builds on top of the broken state.

- **181135f** (set debug off): ✅ PASS
- **02b6873** (enable debug mode): ❌ FAIL ← First failure
- **3b42555** (add startup logging): ❌ FAIL
The first commit where the build breaks is **02b6873**. The previous commit passed all tests, and this is the first commit to fail, indicating this is where the bug was introduced.
## Answer
**02b6873** (or "enable debug mode")

**Bad commit: `77142be` ("enable debug mode")**
**Reasoning:**
Looking at the test results in chronological order:
| Commit | Result |
|--------|--------|
| `3e23312` Initial commit | ✅ PASS |
| `4dd59df` set debug off | ✅ PASS |
| `77142be` enable debug mode | ❌ FAIL |
| `ae5b7ab` add startup logging | ❌ FAIL |
The build was passing up through `4dd59df`, and the first failure occurred at `77142be`. Once a bug is introduced, all subsequent commits continue to fail (as expected). This means **`77142be`** is the commit that broke the build.

# Bad Commit Analysis
**Bad commit: `098e07d` — "enable debug mode"**
## Reasoning
Looking at the test results in chronological order (oldest first):
| Commit | Subject | Result |
|--------|---------|--------|
| d226f66 | Initial commit | ✅ PASS |
| 7d27f9d | set debug off | ✅ PASS |
| **098e07d** | **enable debug mode** | ❌ **FAIL** |
| 758e6f2 | add startup logging | ❌ FAIL |
The build was **passing** through `7d27f9d`, then **first failed** at `098e07d`. Since `758e6f2` also fails (it just inherited the broken state from its parent), the transition point—the commit that actually introduced the bug—is:
**`098e07d` ("enable debug mode")**
This is the classic "first bad commit" that a `git bisect` would converge on: the earliest commit where the status flips from PASS → FAIL.
4614adb
JSON Schema
Structured Output
(raw) {"commit": "4614adb"}
The bad commit is **`3f83d74`** ("enable debug mode").
**Reasoning:**
- `f6acef6` (Initial commit): PASS
- `21caf2e` (set debug off): PASS
- `3f83d74` (enable debug mode): **FAIL** ← first failure
- `9df85ed` (add startup logging): FAIL (inherits the broken state)
The build transitions from PASS to FAIL exactly at `3f83d74`, making it the commit that introduced the bug.
db778d7
JSON Schema
Structured Output
(raw) {"commit": "db778d7"}
The bad commit is **b0b81f5** ("enable debug mode").
This is the first commit where the tests transition from PASS to FAIL. The preceding commit (265986d) passed, and b0b81f5 is where the failure was introduced, with the failure persisting into the subsequent commit (7098fc6).
2b4ccc4
JSON Schema
Structured Output
(raw) {"commit": "2b4ccc4"}
The bad commit is **`28dcb51`** — "enable debug mode".
**Reasoning:**
Looking at the test results in chronological order (oldest to newest):
| Commit | Subject | Result |
|--------|---------|--------|
| cf87eab | Initial commit | ✅ PASS |
| eafdefc | set debug off | ✅ PASS |
| **28dcb51** | **enable debug mode** | ❌ **FAIL** |
| 11efb7b | add startup logging | ❌ FAIL |
The transition from PASS to FAIL occurs at commit **`28dcb51`**. The commit immediately before it (`eafdefc`) still passed, and every commit from `28dcb51` onward fails. This makes `28dcb51` the first bad commit that introduced the bug.

## Analysis
Looking at the test results in chronological order:
| Commit | Subject | Result |
|--------|---------|--------|
| `fc626d3` | Initial commit | ✅ PASS |
| `d1ccc64` | set debug off | ✅ PASS |
| `44517f1` | enable debug mode | ❌ FAIL |
| `fcd9984` | add startup logging | ❌ FAIL |
The build transitions from **PASS → FAIL** at commit `44517f1`. All subsequent commits also fail, indicating the bug was introduced here and never fixed.
## Bad Commit
**`44517f1`**
The commit "enable debug mode" introduced the breaking change. The subsequent commit `fcd9984` ("add startup logging") also fails, but it inherited the broken state rather than causing it.

**4a02b33** — "enable debug mode"
This is the first commit where the build failed (exit code 1), while the preceding commit (6cbeec9) still passed. Since 579b74c continues to fail, it's consistent with the bug being introduced at 4a02b33 rather than fixed or newly broken later.

**Bad commit: `9fbd1e1` - "enable debug mode"**
**Reasoning:**
Looking at the test results in chronological order:
- `905bda9` (Initial commit): PASS
- `aa287ca` (set debug off): PASS
- `9fbd1e1` (enable debug mode): **FAIL** ← first failure
- `089b4fe` (add startup logging): FAIL (still broken)
The build was passing through `aa287ca` and first failed at `9fbd1e1`. Since `089b4fe` also fails, it's possible that commit either didn't fix the issue or introduced unrelated changes on top of an already-broken build — but the regression was clearly introduced by `9fbd1e1`, which is the first commit where the test suite fails. Using bisection logic (last good → first bad), `9fbd1e1` is the culprit.
39b143a enable debug mode
JSON Schema
Structured Output
(raw) {"commit":"39b143a enable debug mode"}
e5734fd
The bad commit is the one that introduced the bug, which is the first commit where the test fails. According to the test results, the test fails starting at commit `f94f590` ("enable debug mode"). The subsequent commit `7cf32d0` also fails because it is built on top of the bad commit.
Thus, the bad commit hash (first 7 characters) is **f94f590** or the subject line **"enable debug mode"**.
49c27b9
4bbb9e8
3e09181
**Reasoning:**
1. **Test Results Order:** The test results are listed oldest first. This means:
* `f365a6d` (Initial commit): PASS
* `b6d5ea1` (set debug off): PASS
* `3e09181` (enable debug mode): FAIL
* `e130804` (add startup logging): FAIL
2. **Identifying the First Failure:** The first commit in the history that causes a test failure is `3e09181` ("enable debug mode"). This is the commit where the build broke for the first time.
3. **Why it's the Bad Commit:** The problem states there is "one bad commit that broke the build". The test results show that the build was working correctly (`PASS`) up to and including `b6d5ea1` ("set debug off"). The very next commit, `3e09181` ("enable debug mode"), caused the build to fail (`FAIL`). Therefore, `3e09181` is the commit that introduced the bug.
4. **Why `e130804` is Not the Bad Commit:** While `e130804` ("add startup logging") also fails, it fails *after* the build was already broken by `3e09181`. It did not introduce the initial bug; it likely exacerbated the existing problem or introduced a separate issue. The problem specifies the commit that "broke the build", meaning the first commit that caused the failure. That is `3e09181`.

The test results indicate that the build failed after the commit `03f1fd4 enable debug mode`. Since this is the first commit in the history that caused a failure (`PASS` to `FAIL`), it is the bad commit that introduced the bug.
**Bad commit hash (first 7 characters):** `03f1fd4`
**Commit subject line:** enable debug mode

Let's analyze step-by-step:
- **Initial commit (`2d3a7f7`)**: PASS
- **`f157449 set debug off`**: PASS
- **`6f207dd enable debug mode`**: FAIL
- **`6eeede5 add startup logging`**: FAIL
The build fails at `6f207dd`, but also fails at `6eeede5`. Since commits are in reverse chronological order, the **bad commit is the earliest one where the failure occurs**—but actually, both `6f207dd` and `6eeede5` fail. However, since `6f207dd` comes before `6eeede5` in the log, it means `6f207dd` was committed after `f157449` and before `6eeede5`.
But the **build fails at `6f207dd`**, so that commit is suspect. The next commit (`6eeede5`) also fails, but that could be due to changes from `6f207dd`.
However, the **first commit that introduces the bug** is typically the one whose changes cause the failure when applied. Here, `6f207dd` enables debug mode, which might have changed behavior leading to the failure in `6eeede5`. But since `6f207dd` itself causes a FAIL, it's likely the culprit.
But let's check the order:
- Newest: `6eeede5`
- Then: `6f207dd`
- Then: `f157449`
- Oldest: `2d3a7f7`
So the sequence is:
```
6eeede5 add startup logging (FAIL)
6f207dd enable debug mode (FAIL)
f157449 set debug off (PASS)
2d3a7f7 Initial commit (PASS)
```
Since `6f207dd` is the first commit that fails, and it's before `6eeede5`, it's possible that `6f207dd` introduced the bug.
**Conclusion:** The bad commit is `6f207dd`.
**Answer:** `6f207dd`

The bad commit is **1c59cb4 enable debug mode**.
Here’s the reasoning:
1. The test results show the build was working up to commit **5befbf7 set debug off** (PASS).
2. The first failing test is at **1c59cb4 enable debug mode** (FAIL).
3. The next commit **8f5937c add startup logging** also fails, but since the bug was already introduced in **1c59cb4**, that is the culprit.
Thus, **1c59cb4** is the commit that broke the build.
Answer: `1c59cb4` or `enable debug mode`.

Reasoning: `29cab13` and `d47b963` both pass, while `70cde84` is the first commit to fail. The later commit `f3642d1` also fails only because it inherits the breakage introduced in `70cde84`.

**Bad commit: `e443762` — "enable debug mode"**
**Reasoning:**
Using a bisect-style analysis of the test results:
| Commit | Result |
|--------|--------|
| 86947a6 Initial commit | ✅ PASS |
| f7d710a set debug off | ✅ PASS |
| **e443762 enable debug mode** | ❌ **FAIL** ← first failure |
| 3ca5bc5 add startup logging | ❌ FAIL |
The last passing commit is `f7d710a`, and the first failing commit is `e443762`. Since the build broke exactly when "enable debug mode" was introduced and remained broken afterward, `e443762` is the commit that introduced the bug. The subsequent commit (`3ca5bc5`) merely inherited the broken state — it didn't cause it.
**Bad commit: `0d9a245`** — "enable debug mode"
**Reasoning:**
- `6ba034d` (Initial commit): PASS ✓
- `a9eb63e` (set debug off): PASS ✓
- `0d9a245` (enable debug mode): **FAIL ✗** ← first failing commit
- `1f6f4b4` (add startup logging): FAIL ✗
Since `a9eb63e` passes and `0d9a245` is the first commit where the build breaks, commit **`0d9a245`** ("enable debug mode") introduced the bug. The subsequent commit `1f6f4b4` still fails because it builds on top of the broken commit.
## Bad Commit: `a74c8a7` ("enable debug mode")
**Reasoning:**
Walking through the commits chronologically:
| Commit | Subject | Result |
|--------|---------|--------|
| 7ead79f | Initial commit | ✅ PASS |
| 265241f | set debug off | ✅ PASS |
| **a74c8a7** | **enable debug mode** | ❌ **FAIL** |
| 0703264 | add startup logging | ❌ FAIL |
The build passed at `265241f` but broke at the very next commit, `a74c8a7`. Since `0703264` also fails but its parent (`a74c8a7`) already fails, `0703264` merely inherited the broken state.
**The bug was introduced in `a74c8a7` ("enable debug mode")** — likely enabling debug mode triggered a crash, missing config, or an assertion failure at runtime.
**Bad commit: `2fa9a18` — "enable debug mode"**
**Reasoning:**
- `5f61e17` (Initial commit): PASS
- `39d83ea` (set debug off): PASS — last known good commit
- `2fa9a18` (enable debug mode): FAIL — first commit where the build breaks
- `ee158d2` (add startup logging): FAIL — still broken, but it inherited the bug
Since `39d83ea` passes and its immediate child `2fa9a18` fails, `2fa9a18` ("enable debug mode") is the commit that introduced the bug. The subsequent commit `ee158d2` fails only because the bug was already present.
200afff — “enable debug mode”
f875f32
**Bad commit: `fe85d92` — "enable debug mode"**
**Reasoning:**
- `5e44821` (Initial commit): PASS
- `868cfde` (set debug off): PASS
- `fe85d92` (enable debug mode): **FAIL** ← first failure
- `0710ad5` (add startup logging): FAIL
Since `868cfde` is the last passing commit and `fe85d92` is the very next commit where the build breaks, the bug was introduced in **`fe85d92` ("enable debug mode")**. The subsequent commit `0710ad5` still fails, which confirms it inherited the broken state rather than introducing it.
**Bad commit: `c910813` — "enable debug mode"**
**Reasoning:**
- `9ac8725` (Initial commit): PASS
- `9e587be` (set debug off): PASS ← last known good commit
- `c910813` (enable debug mode): **FAIL** ← first bad commit
- `23d6215` (add startup logging): FAIL
Since `9e587be` passes and the very next commit `c910813` fails, the bug was introduced by **`c910813`** ("enable debug mode"). The later commit (`23d6215`) still fails because the bug persists, but it didn't introduce it.

ef9a56a
JSON Schema
Structured Output
(raw) {"commit": "ef9a56a"}
Looking at the git commit history and test results, I can identify the bad commit by analyzing when the tests started failing.
From the test results (oldest to newest):
- 2c61653 (Initial commit): PASS
- 0efe0e5 (set debug off): PASS
- 9763e52 (enable debug mode): FAIL
- 1066e31 (add startup logging): FAIL
The tests passed up to commit 0efe0e5, but failed starting with commit 9763e52. This indicates that commit 9763e52 "enable debug mode" is the bad commit that broke the build, as it's the first commit where the tests began failing.
The answer is: 9763e52

The bad commit is **7d6cac8** ("enable debug mode").
**Explanation:**
- The earliest failure occurs at commit `7d6cac8`, which introduced a change that broke the build.
- Subsequent commits (e.g., `da3d8d6`) inherit the failure, confirming the bug was introduced in `7d6cac8`.
- The commit subject is "enable debug mode".

Based on the commit history and test results, we can determine the "bad" commit by looking for the first commit in the sequence where the test results change from **PASS** to **FAIL**.
1. **34f35c5** (Initial commit): **PASS**
2. **14a2701** (set debug off): **PASS** (Still working)
3. **d6fb636** (enable debug mode): **FAIL** (The bug was introduced here)
4. **28f593b** (add startup logging): **FAIL** (The build remains broken)
The first commit to cause the failure is `d6fb636`.
**d6fb636** (or "enable debug mode")

The bad commit is **059a362** (`enable debug mode`).
**Reasoning:** Looking at the test results chronologically, the build passes for `b90a5ae` and `9dc9bb3`, but first fails at `059a362`. Since `059a362` is the earliest commit where the test fails, it is the commit that introduced the bug. The subsequent commit `b75806d` also fails because it inherits the bug from `059a362`.
2024b24

The bad commit is **`55b76cd`** ("enable debug mode").
**Reasoning:**
Looking at the test results in chronological order:
| Commit | Subject | Result |
|--------|---------|--------|
| `851817a` | Initial commit | ✅ PASS |
| `773910d` | set debug off | ✅ PASS |
| `55b76cd` | enable debug mode | ❌ **FAIL** |
| `dbd1b3a` | add startup logging | ❌ FAIL |
The first transition from **PASS → FAIL** occurs at commit `55b76cd` ("enable debug mode"). Since the previous commit (`773910d`) passed and `55b76cd` failed, this is the commit that introduced the bug. The subsequent commit `dbd1b3a` continues to fail as well, confirming it inherited the broken state.
## Identifying the Bad Commit
Looking at the test results from oldest to newest:
| Commit | Subject | Result |
|--------|---------|--------|
| eecc0eb | Initial commit | ✅ PASS |
| 388dfca | set debug off | ✅ PASS |
| f9cc79e | enable debug mode | ❌ FAIL |
| f90cd29 | add startup logging | ❌ FAIL |
The first failure appears between `388dfca` (PASS) and `f9cc79e` (FAIL).
**The bad commit is `f9cc79e` ("enable debug mode")** — this is the first commit that broke the build. All subsequent commits also fail because they inherit the bug introduced here.
The bad commit is **e9e4da3** ("enable debug mode").
Here's the reasoning:
1. **e9b1ef8** `Initial commit` → PASS ✅
2. **8b5d45a** `set debug off` → PASS ✅
3. **e9e4da3** `enable debug mode` → **FAIL** ❌
4. **df28e40** `add startup logging` → FAIL ❌ (inherits the bug from e9e4da3)
The test passed at commit `8b5d45a` and first failed at commit `e9e4da3`, meaning the change introduced in `enable debug mode` broke the build. Since enabling debug mode caused an exit code 1, the debug functionality itself is the source of the bug.
7d9df82
The bad commit is **8f97e1d** ("enable debug mode").
The test results show:
- `8023052 set debug off`: **PASS**
- `8f97e1d enable debug mode`: **FAIL** ← first failure
The commit `8f97e1d` is where the build first broke.

The subsequent commit 742f0b3 also fails, but that is expected once the repository already contains the breaking change. Consequently the regression was introduced by the diff that 2148d45 itself brought in.

Invalid JSON. Output: To identify the **bad commit**, let's analyze the information step-by-step:
### Step 1: Understand the commit order
The commits are listed from newest to oldest:
- **9f28f9c** – Add startup logging
- **5514158** – Enable debug mode
- **bfea037** – Set debug off
- **1450b9f** – Initial commit
### Step 2: Analyze test results
- **1450b9f**: PASS (no issues)
- **bfea037**: PASS (no issues)
- **5514158**: FAIL (bug introduced here)
- **9f28f9c**: FAIL (bug persists here)
This means the bug was introduced in commit **5514158** ("enable debug mode"), since it's the first commit where tests fail.
### Step 3: Confirm with commit message
The commit message for **5514158** is "enable debug mode".
