Model Outputs (546)
**Bad commit: `f470ad5` — "change port"**
The bisection logic is straightforward:
- `b773631` (Initial commit): PASS ✅
- `4decdd6` (add default config): PASS ✅
- `f470ad5` (change port): **FAIL** ❌ ← first failing commit
- `08dd536` and `124a846` fail because they build on top of the broken commit
The transition from PASS to FAIL occurs at **f470ad5 "change port"**, making it the commit that introduced the bug.
e522775
JSON Schema
Structured Output
(raw) {"commit": "e522775"}
fdd31c7 — "change port" is the bad commit (first failing commit after passing 50e3c78).
92d9e55
JSON Schema
Structured Output
(raw) {"commit": "92d9e55"}
**Bad commit: `52207d6` — "change port"**
**Reasoning (bisect logic):**
Walking through the test results in chronological order:
| Commit | Subject | Result |
|--------|---------|--------|
| 29d9f37 | Initial commit | ✅ PASS |
| 1d19aca | add default config | ✅ PASS |
| **52207d6** | **change port** | ❌ **FAIL** ← first failure |
| 18f8243 | add feature flag | ❌ FAIL |
| fd6bfb9 | add port constant | ❌ FAIL |
The build passed through `1d19aca` and first failed at `52207d6`. All subsequent commits fail because they build on top of the broken state. Therefore, the commit that introduced the bug is **`52207d6` ("change port")** — the transition point from PASS to FAIL.
06b4c76
JSON Schema
Structured Output
(raw) {"commit": "06b4c76"}
The bad commit is **3c0ca42** ("change port").
Tests pass through 977447f, then first fail at 3c0ca42, so that commit introduced the bug.
03c2548
JSON Schema
Structured Output
(raw) {"commit": "03c2548"}
**Bad commit: `8743a9c` — "change port"**
Reasoning (bisect-style analysis):
- `1c6d822` (Initial commit): PASS ✅
- `a9527e6` (add default config): PASS ✅
- `8743a9c` (change port): **FAIL ❌ ← first failing commit**
- `b405076` (add feature flag): FAIL (inherited breakage)
- `7068f52` (add port constant): FAIL (inherited breakage)
The build transitions from PASS to FAIL at commit `8743a9c` ("change port"), making it the commit that introduced the bug. The subsequent failures are just downstream of that broken commit.
45a7cb5
JSON Schema
Structured Output
(raw) {"commit": "45a7cb5"}
# Analysis
Looking at the test results chronologically:
- **245e3ea** (Initial commit): PASS ✓
- **7811356** (add default config): PASS ✓
- **ec9b625** (change port): FAIL ✗ ← First failure
- **c712735** (add feature flag): FAIL ✗
- **fba7d17** (add port constant): FAIL ✗
The build passes through the first two commits, then fails starting with **ec9b625**. All subsequent commits also fail, but the root cause is introduced in the first failing commit.
**Answer: `ec9b625` (or "change port")**
3a3c3de
JSON Schema
Structured Output
(raw) {"commit": "3a3c3de"}
# Answer
**7ec2e18** (change port)
## Reasoning
Looking at the test results in chronological order:
- d831f40 (Initial commit): PASS ✓
- f8f7c44 (add default config): PASS ✓
- **7ec2e18 (change port): FAIL ✗** ← First failure
- 48dd8c0 (add feature flag): FAIL
- f1d6bf2 (add port constant): FAIL
The commit **7ec2e18** is the first commit where the build breaks. All commits before it pass, and all commits after it (which build on top of it) also fail. This indicates that the bug was introduced in the "change port" commit.

# Analysis
Looking at the test results in chronological order:
1. **c678aa5** (Initial commit): ✅ PASS
2. **184d4da** (add default config): ✅ PASS
3. **37b28a0** (change port): ❌ FAIL ← Tests start failing here
4. **57b68b1** (add feature flag): ❌ FAIL
5. **d68e331** (add port constant): ❌ FAIL
The first commit where tests failed is **37b28a0**, immediately after the last passing commit.
**Answer: 37b28a0** (or "change port")
a80eb8a
JSON Schema
Structured Output
(raw) {"commit": "a80eb8a"}
The bad commit is **f2c7a45** (change port).
This is the first commit where the tests start failing. The commit "change port" introduced the bug that broke the build, and all subsequent commits also fail, indicating the bug was never fixed in later commits.

- **8cd75c3** (change port): **FAIL** ✗ ← First failure
- **dc870e6** (add feature flag): FAIL ✗
- **b8e9d28** (add port constant): FAIL ✗
The build was passing up to commit `4cb8ea7`, and the first commit where tests start failing is `8cd75c3`. This is where the bug was introduced.
**Answer: `8cd75c3` or `change port`**
f9fcce5

b96fc77
JSON Schema
Structured Output
(raw) {"commit":"b96fc77"}
**Bad commit: `1f72311` ("change port")**
**Reasoning:** The test results show that all commits up to and including `7b5cf24` (add default config) pass, but starting from `1f72311` (change port), all subsequent commits fail. This means `1f72311` is the first commit that introduced the failure, making it the bad commit. The later failures (`369d375`, `9e293fe`) are simply inheriting the bug introduced by `1f72311`.

Looking at the test results chronologically:
- `a5ea606` Initial commit: **PASS**
- `ecadd69` add default config: **PASS**
- `493936e` change port: **FAIL** ← First failing commit
- `f82070d` add feature flag: FAIL
- `db116a1` add port constant: FAIL
The transition from PASS to FAIL occurs at commit `493936e` "change port". All subsequent commits inherit the broken state.
**Bad commit: `493936e` (change port)**

The bad commit is **`54e2ca6`** ("change port").
The test results show a clear transition from PASS to FAIL:
- `d9ade0b` — PASS ✅
- `54e2ca6` — **FAIL** ❌ (first failing commit)
- All subsequent commits remain FAIL
Since `54e2ca6` is the first commit where the build broke (and everything before it passed), it introduced the bug.

**Bad commit: `e99e829` ("change port")**
## Reasoning
Looking at the test results in chronological order (oldest to newest), I can find the transition point from passing to failing:
| Commit | Subject | Result |
|--------|---------|--------|
| 46f7337 | Initial commit | ✅ PASS |
| c1e3c4e | add default config | ✅ PASS |
| **e99e829** | **change port** | ❌ **FAIL** ← first failure |
| 417e7a1 | add feature flag | ❌ FAIL |
| 726269e | add port constant | ❌ FAIL |
The build was healthy through `c1e3c4e`, then broke starting at `e99e829`. Since every commit **before** `e99e829` passes and every commit **from** `e99e829` onward fails, this is the commit that introduced the bug.
The two later failures (`417e7a1` and `726269e`) are just inheriting the already-broken state — they aren't the root cause.
This is exactly the transition point `git bisect` would converge on:
```
git bisect start
git bisect bad 726269e # newest, known bad
git bisect good c1e3c4e # known good
# → bisect would identify e99e829 as the first bad commit
```
6212044
JSON Schema
Structured Output
(raw) {"commit": "6212044"}
**8cf4ce6** ("change port")
This is the bad commit. The build passes at `01283e1` and fails starting at `8cf4ce6`, with all subsequent commits inheriting the failure. Since `8cf4ce6` is the first commit to show FAIL (exit code 1), it introduced the bug.
51f6a3d
JSON Schema
Structured Output
(raw) {"commit": "51f6a3d"}
The bad commit is **`07945c2`** (`change port`).
This is the first commit where the tests transition from PASS to FAIL. The commit immediately before it (`237b285 add default config`) passes, and every commit from `07945c2` onward fails, indicating this commit introduced the bug that broke the build.
71c81de
JSON Schema
Structured Output
(raw) {"commit": "71c81de"}
**Bad commit: `63e0c22` ("change port")**
**Reasoning:**
Looking at the test results in chronological order (oldest → newest):
| Commit | Subject | Result |
|--------|---------|--------|
| d842fbb | Initial commit | ✅ PASS |
| 1f7e8c5 | add default config | ✅ PASS |
| **63e0c22** | **change port** | ❌ **FAIL** ← first failure |
| cf3fea9 | add feature flag | ❌ FAIL |
| 3191943 | add port constant | ❌ FAIL |
The build transitions from **PASS → FAIL** exactly at commit `63e0c22`. Every commit before it passes, and every commit from it onward fails. This is the classic bisection signature of a bug-introducing commit — `63e0c22` ("change port") is the culprit.
61e18d4
JSON Schema
Structured Output
(raw) {"commit": "61e18d4"}
The bad commit is **71a906d** ("change port"), as it's the first commit where the tests began failing.

## Analysis
Looking at the test results ordered from oldest to newest:
| Commit | Subject | Result |
|--------|---------|--------|
| `4f6a54e` | Initial commit | ✅ PASS |
| `d7df229` | add default config | ✅ PASS |
| `53ebe29` | change port | ❌ FAIL |
| `5b714a2` | add feature flag | ❌ FAIL |
| `ef46624` | add port constant | ❌ FAIL |
The build passes through `d7df229` and first breaks at `53ebe29`. All subsequent commits also fail, which is consistent with a bug being introduced and never fixed.
## Answer
**`53ebe29`**
The bad commit is `53ebe29` — **"change port"** — which is the first commit where the build transitions from PASS to FAIL.

**fa13c82** (commit subject: "change port")
This is the first commit where the test suite transitions from PASS to FAIL, and all subsequent commits remain in a FAIL state — consistent with a bug introduced at this point that was never fixed. Using a bisection approach: since `67cc397` passes and `fa13c82` fails, the bug was introduced in `fa13c82`.

The first commit that caused a test failure is `ec54197` with the subject line "change port". This is the bad commit that introduced the bug.
The first commit that causes the test to fail is `4206cd3` ("change port"). Since the build was passing in previous commits and all subsequent commits also fail, this is the bad commit that introduced the bug.
Answer: 4206cd3
The bad commit is `a8c0038` with the subject line "change port", as it is the first commit where the tests fail (exit code 1), indicating the introduction of the bug.
24c9788**Reasoning:**
1. **Test Results Order:** The test results are listed from oldest commit to newest. This means the first test result (e0808de) is the oldest commit, and the last test result (18b1429) is the newest.
2. **Failure Pattern:** The test results show that commits `e0808de` and `8035a76` passed (exit code 0). All commits after that (`24c9788`, `3566a0b`, `18b1429`) failed (exit code 1).
3. **First Failure:** The first commit to fail is `24c9788` ("change port"). Since the build was working before this commit (as `e0808de` and `8035a76` passed), this commit is the one that introduced the bug.
4. **Subsequent Failures:** While commits `3566a0b` ("add feature flag") and `18b1429` ("add port constant") also failed, the bug was already introduced in `24c9788`. Their failures are a consequence of the existing bug, not the initial cause.
Therefore, the bad commit that broke the build is `24c9788`.

033e4de
**Reasoning:**
1. **Test Results Order:** The test results are listed from oldest to newest commit.
2. **Pass/Fail Pattern:** The first two commits (9b35f91 and e3ca556) passed. The third commit (033e4de) failed. The subsequent commits (3ec7f16 and ae56a64) also failed.
3. **Root Cause:** The failure starts at commit `033e4de`. This is the first commit where the test fails. While commits `3ec7f16` and `ae56a64` also fail, they are likely failing *because* the code was already broken by `033e4de`. The bug was introduced in `033e4de`.
4. **Bad Commit:** Therefore, the commit that introduced the bug is `033e4de`.

(raw) {"commit": "5c42104"}
To find the commit that introduced the bug, we can look at the test results in sequential order, from the oldest commit to the newest. The first commit to fail the test is the one that broke the build.
Looking at your test results:
- 2c7b328 Initial commit: PASS
- 2d8ebce add default config: PASS
- **ad98c36 change port: FAIL**
- e05c3b9 add feature flag: FAIL
- eab2aa7 add port constant: FAIL
The build was passing until the "change port" commit. Therefore, the commit that introduced the bug is:
**ad98c36** (or "change port")

The failing test results indicate that the build started to fail with commit **fd549ee** ("change port"). While subsequent commits (8a9ca30 and eb4f8b8) also cause failures, the first occurrence of a failure marks the introduction of the bug. Therefore, the bad commit hash (first 7 characters) is:
**fd549ee**
b65edc6
JSON Schema
Structured Output
(raw) {"commit": "b65edc6"}
The bad commit is **0548f17** ("change port").
The test results show that the first failure occurs at commit `0548f17` ("change port"). All earlier commits pass, and all later commits also fail — indicating the bug was introduced by this commit.

Based on the test results, the first commit that introduced the bug is `568c638 change port`, as it's the first commit in the history (when read from oldest to newest) that shows a FAIL result. All subsequent commits also fail, which suggests the bug was introduced in this commit and not fixed in later ones.
The bad commit is: `568c638` (or "change port")
64587a0
JSON Schema

The test results show that the build was passing up to commit `68c4469` (add default config) and first failed at commit `d86431b` (change port). All subsequent commits also failed, confirming that `d86431b` is the first bad commit.

The first failing commit is `c74dee0 change port`, and all subsequent commits also fail. Since the two commits before it (`7c42a6e` and `06d7f35`) pass, **`c74dee0` is the bad commit that broke the build**.
c74dee0
bb44116
JSON Schema
Structured Output
(raw) {"commit": "bb44116"}
The bad commit is `866d255` (commit subject: "change port").
This is because:
1. The test passes for commits 92b49cc and ec4870e
2. The test first fails at commit 866d255
3. All subsequent commits (459760d and f0bd616) also fail, indicating the bug was introduced in 866d255 and never fixed
Therefore, the bad commit is `866d255`.
133805c
JSON Schema
Structured Output
(raw) {"commit": "133805c"}
The test passes for the first two commits (Initial commit and add default config) but starts failing at **86a96d1 change port** and continues to fail for all subsequent commits. This indicates the bug was introduced in that commit.

This is the first commit in the test results that fails, so it introduced the bug.
6deddd5
JSON Schema
Structured Output
(raw) { "commit": "6deddd5" }
**Bad commit: `7d91952` — "change port"**
**Reasoning:**
- `8418c12` (Initial commit) → PASS
- `fec8d96` (add default config) → PASS
- `7d91952` (change port) → **FAIL** ← first failure appears here
- `aa9a67b` (add feature flag) → FAIL
- `2e250f3` (add port constant) → FAIL
Since the build passed at `fec8d96` and first failed at `7d91952`, the commit `7d91952` ("change port") is the one that introduced the bug. All subsequent commits fail because they build on top of it.
3fd5f9d — “change port”
**Bad commit: `3e5ff9c` — "change port"**
**Reasoning:** The build passed at `0be0239` (Initial commit) and `9059f8d` (add default config), but began failing at `3e5ff9c` (change port). Every commit after it also fails, which is consistent with the bug being introduced at `3e5ff9c` and persisting through all subsequent commits. Since `9059f8d` is the last passing commit and `3e5ff9c` is the first failing one, `3e5ff9c` is the commit that introduced the bug.
47b7e6a — “change port”
**Bad commit: `6c2bdb2` — "change port"**
**Reasoning:** Walking the history from oldest to newest:
- `ac52625` (Initial commit) — PASS
- `cea3e3f` (add default config) — PASS
- `6c2bdb2` (change port) — **FAIL** ← first failure
- `0d38f59` and `8b2dcd5` — FAIL (they inherit the breakage)
Since `cea3e3f` is the last passing commit and `6c2bdb2` is the first failing one, the bug was introduced in `6c2bdb2` ("change port"). The subsequent commits remain broken because they build on top of this bad change — notably, the later commit "add port constant" (`8b2dcd5`) didn't fix the port change that broke things.
**Bad commit: `9785417` — "change port"**
The tests pass on the first two commits (`099c6ca` and `f0ac59d`), but `9785417` is the first commit where the test suite fails (exit code 1). Since every subsequent commit also fails, `9785417` is the commit that introduced the bug. In a `git bisect` workflow, this is exactly what bisection would converge on: the transition point from PASS to FAIL.
**Bad commit: `f3f268d` ("change port")**
**Reasoning:** This follows the standard git bisect logic — the bad commit is the *first* commit where the test transitions from PASS to FAIL:
| Commit | Result |
|--------|--------|
| `5135b3c` Initial commit | ✅ PASS |
| `3f0417f` add default config | ✅ PASS |
| **`f3f268d` change port** | ❌ **FAIL** ← first failure |
| `02a8090` add feature flag | ❌ FAIL |
| `4a477bd` add port constant | ❌ FAIL |
Since `3f0417f` passes and `f3f268d` is the first commit to fail — with all subsequent commits also failing — the bug was introduced in **`f3f268d` ("change port")**. The later commits didn't break the build; they just inherited the breakage.
**Bad commit: `c80ca9b` ("change port")**
**Reasoning:**
- `7872e04` (Initial commit) → PASS
- `8b1fa3e` (add default config) → PASS
- `c80ca9b` (change port) → **FAIL** ← first failure
- `52f414c` (add feature flag) → FAIL
- `5866934` (add port constant) → FAIL
The tests pass through `8b1fa3e` and first fail at `c80ca9b`. Since the bug appears in every commit from `c80ca9b` onward and in none before it, `c80ca9b` ("change port") is the commit that introduced the bug.
7580a34 — “change port”
**Bad commit: `67d36d9` — "change port"**
**Reasoning:** Walking the history from oldest to newest:
- `292f6dc` (Initial commit): PASS
- `89c2ea8` (add default config): PASS
- `67d36d9` (change port): **FAIL** ← first failure
- `007502d` (add feature flag): FAIL
- `a3db15d` (add port constant): FAIL
Since `89c2ea8` is the last passing commit and `67d36d9` is the first failing commit — with every subsequent commit also failing — the bug was introduced in `67d36d9` ("change port"). This matches a classic git bisect result: the transition point from PASS to FAIL identifies the culprit.

The bad commit is c39c7b5.
**Reasoning:**
- Tests passed for commits up to `64cfbfc` (add default config).
- The first failure occurred at `c39c7b5` (change port).
- Subsequent commits (`a7392e4`, `b6512db`) inherit the broken state, but the root cause is the first failing commit.
Answer: c39c7b5
c3b1c4b
JSON Schema
Structured Output
(raw) {
"commit": "c3b1c4b"

The bad commit is the first one that caused the test to fail. The test passed for the initial commit and adding the default config, but failed when the port was changed. Subsequent commits also failed, so the root cause is the first failure point.
**Answer:** 541e4f1
65ed133
JSON Schema
Structured Output
(raw) {"commit": "65ed133"}
The bad commit is **6c1830a**.
**Reasoning:**
The test results show that the build passes for commits up to `5f75dcf` (add default config). The first failure occurs at `6c1830a` (change port), which introduces the bug. Subsequent commits (`63d57e1` and `ad2fe17`) inherit the failure but are not the root cause. The commit subject line for `6c1830a` is "change port", but the hash is the direct identifier.
**Answer:**
6c1830a

0f7a8ea
JSON Schema
Structured Output
(raw) {
"commit": "0f7a8ea"

The bad commit is f984149.
**Explanation:**
- The test results show that the first failure occurs at commit `f984149` (change port).
- All subsequent commits build on top of this commit and inherit the failure.
- Since the commits before `f984149` (`6751886` and `ed833b4`) passed, the bug must have been introduced in `f984149`.
Answer: `f984149`
3fc937a
JSON Schema
Structured Output
(raw) {"commit": "3fc937a"}
Looking at the test results chronologically:
- 6b98fd7 Initial commit: PASS
- aac878b add default config: PASS
- 2dcacd9 change port: **FAIL** ← First failure
The tests pass until commit `2dcacd9` ("change port"), which is the first commit to fail. This is the bad commit that introduced the bug.
**Answer: 2dcacd9**
708b7ef
JSON Schema
Structured Output
(raw) {

**Answer:** f1530aa
410ca02
JSON Schema
Structured Output
(raw) {"commit":"410ca02"}
Based on the test results, I can see that:
1. **b76f4f4 Initial commit**: PASS
2. **7d9e007 add default config**: PASS
3. **880a821 change port**: FAIL ← First failure
The build was passing up to and including commit `7d9e007`, but then failed starting with commit `880a821`. This indicates that commit introduced the bug.
**Bad commit: 880a821**
533e500
JSON Schema

- Commit `8f190a8` fails and all subsequent commits also fail
The bad commit is `8f190a8` with the subject "change port".

- e063001 change port: FAIL
The tests pass up until commit `c2f9ff2`, but fail starting with `e063001`. This means the bug was introduced in commit `e063001` with the subject "change port".

Based on the test results, the build was passing at commit `057a7ef` and started failing at commit `8b43555`. Since the tests are ordered oldest first and the first failure occurs at `8b43555`, this is the commit that introduced the bug.
**8b43555**
1e4f5bc
The bad commit is **88a0e8f** ("change port").
This is the first commit where the test fails. The previous commit `067279f` ("add default config") passed, so `88a0e8f` is the commit that introduced the bug.
The bad commit is **b2c205a** (subject: "change port").
Reasoning: This is the first commit in the history (from oldest to newest) where the test result transitions from PASS to FAIL. The previous commit `383caed add default config` passed, and the very next commit `b2c205a change port` failed. This makes `b2c205a` the commit that introduced the bug.
The bad commit is **c70f1fe** with the subject line **"change port"**.
This is the first commit where the test result changed from PASS to FAIL. The previous commit (`17bb20f add default config`) passed, so `c70f1fe change port` is the commit that introduced the bug.

The bad commit is **cfe90e3** ("change port").
**Reasoning:** This is a straightforward git bisect scenario. Looking at the test results from oldest to newest:
- `a12ed55` Initial commit: **PASS** ✅
- `ecc82d2` add default config: **PASS** ✅
- `cfe90e3` change port: **FAIL** ❌
- `891b912` add feature flag: **FAIL** ❌
- `6fd9c36` add port constant: **FAIL** ❌
The last passing commit is `ecc82d2`, and the first failing commit is `cfe90e3`. Therefore, `cfe90e3` introduced the bug. All subsequent commits continue to fail, consistent with the build remaining broken from that point forward.

The test results show that commits 61ffcf6 and 5ed0c1f both pass. The very next commit in the history (541e4f1) is the first one to produce a failing test. All later commits continue to fail, confirming that the bug was introduced exactly when "change port" landed and was never subsequently fixed.
Thus the bad commit is 541e4f1.
Final answer: 541e4f1

The commit history is linear, and the provided test results explicitly show a clean pass/fail transition point. The two oldest commits both exit with code 0 (green builds). The third commit, `1f21d76`, is the first one whose test run exits with a non-zero code; every subsequent commit also fails.
Consequently the single commit that introduced the regression is the one whose subject line is “change port” (hash `1f21d76`).
Final answer: 1f21d76
