Model Outputs (760)
The first failing commit is **0f23e97** ("switch to dev") — the commit before it passes and every commit from it onward fails, so it introduced the bug.
97af815
JSON Schema
Structured Output
(raw) {"commit": "97af815"}
The bad commit is **4d8b06a** ("switch to dev") — it's the first commit where tests transition from PASS to FAIL.
e301880
JSON Schema
Structured Output
(raw) {"commit": "e301880"}
**Bad commit: `d63579d` — "switch to dev"**
Reasoning: Walking the history oldest → newest, the tests pass at `8e9a979` (Initial commit) and `c61a2a9` (setup production env), then flip to FAIL at `d63579d` (switch to dev) and stay failing at `5df68aa` (add diagnostics). The first commit where the build transitions from PASS to FAIL is `d63579d`, so that's the commit that introduced the bug; `5df68aa` is just inheriting the breakage.
9bf2ef6
JSON Schema
Structured Output
(raw) {"commit": "9bf2ef6"}
The first failing commit is **090a138** — "switch to dev". The previous commit (5bf03f3) passed, and this one fails, so it introduced the bug.
04fe569
JSON Schema
Structured Output
(raw) {"commit": "04fe569"}
The first failing commit is **1083ea5** ("switch to dev"). The commit before it (f9fb574) passes, and this one fails, so it introduced the bug.
bff3ffe
JSON Schema
Structured Output
(raw) {"commit":"bff3ffe"}
**Bad commit: `5ad22da` — "switch to dev"**
Reasoning:
- `e166b1a` (Initial commit): PASS
- `ce0b34d` (setup production env): PASS
- `5ad22da` (switch to dev): **FAIL** ← first failing commit
- `751353e` (add diagnostics): FAIL (inherited the breakage)
The build passed through `ce0b34d` and first failed at `5ad22da`, so "switch to dev" introduced the bug.
6fdd1b5
JSON Schema
Structured Output
(raw) {"commit": "6fdd1b5"}
The bad commit is **30e5854** — "switch to dev". It's the first commit where tests fail (all earlier commits pass, all commits from this point on fail).
6358750
JSON Schema
Structured Output
(raw) {"commit": "6358750"}
**Bad commit: `3dbab3d` — "switch to dev"**
**Reasoning:**
Walking through the test results in chronological order (oldest first):
| Commit | Subject | Result |
|--------|---------|--------|
| af6bbf8 | Initial commit | ✅ PASS |
| 9b32d74 | setup production env | ✅ PASS |
| 3dbab3d | switch to dev | ❌ FAIL ← first failure |
| 183a087 | add diagnostics | ❌ FAIL |
The build transitions from PASS to FAIL exactly at commit `3dbab3d` ("switch to dev"). All commits before it pass, and all commits after it (including it) fail — meaning this commit introduced the bug. The subsequent commit `183a087` just inherits the broken state.
98b3ee9
JSON Schema
Structured Output
(raw) {"commit": "98b3ee9"}
The bad commit is **6603f51** — "switch to dev"
Reasoning: Tests pass through `a92d5fa` (setup production env), then first fail at `6603f51` (switch to dev), and continue failing afterward. The first failing commit is the one that introduced the bug.
723e42a
JSON Schema
Structured Output
(raw) {"commit": "723e42a"}
**Bad commit: `9eb9eeb` — "switch to dev"**
**Reasoning:**
Walking through the test results in chronological order (oldest → newest):
| Commit | Subject | Result |
|--------|---------|--------|
| 34c015c | Initial commit | ✅ PASS |
| 9b05052 | setup production env | ✅ PASS |
| 9eb9eeb | switch to dev | ❌ FAIL |
| 9244d97 | add diagnostics | ❌ FAIL |
The build transitions from **PASS → FAIL** between `9b05052` and `9eb9eeb`. Since `9b05052` passes and `9eb9eeb` is the first commit to fail, `9eb9eeb` ("switch to dev") introduced the bug. The subsequent commit `9244d97` also fails, but only because it inherited the breakage — it isn't the root cause.

# Debugging Analysis
Looking at the test results in chronological order:
1. **f0ad375** (Initial commit): ✅ PASS
2. **3c374a0** (setup production env): ✅ PASS
3. **b88d1d0** (switch to dev): ❌ FAIL
4. **e7f3c6f** (add diagnostics): ❌ FAIL
The test passes through commit `3c374a0` but fails starting at commit `b88d1d0`. This means the bug was introduced in the `b88d1d0` commit.
The subsequent commit `e7f3c6f` also fails, but that's a consequence of the bug introduced earlier.
**Answer: `b88d1d0`** (or "switch to dev")

- d2724d3 (switch to dev): **FAIL** ✗ ← First failure
- 2b6d0a8 (add diagnostics): **FAIL** ✗ (still broken)
The commit **d2724d3** is the first one that caused the test to fail. The subsequent commit (2b6d0a8) also fails because the bug was already introduced by d2724d3, and "add diagnostics" didn't fix the underlying issue.
b79d35a

Looking at the test results, I can identify where the build started failing:
- `b0b929d` Initial commit: PASS ✓
- `d25c745` setup production env: PASS ✓
- `9e80a6e` switch to dev: **FAIL** ✗ ← First failure
- `7e24241` add diagnostics: FAIL ✗
The bad commit is **`9e80a6e`** ("switch to dev"), as this is the first commit where the tests began failing. The subsequent commit `7e24241` merely inherits the failure from this commit.

- `0cbd97b` switch to dev: **FAIL** ← first failure
- `1379f72` add diagnostics: **FAIL** (inherited failure)
The build was passing through `c7e4b88` and then broke at `0cbd97b`. Since `0cbd97b` is the first commit where the test transitions from PASS to FAIL, it introduced the bug. The subsequent commit `1379f72` merely inherits the broken state.

## Analysis
Looking at the test results chronologically (oldest → newest):
| Commit | Subject | Result |
|--------|---------|--------|
| c03c241 | Initial commit | ✅ PASS |
| e64584a | setup production env | ✅ PASS |
| e164ccf | switch to dev | ❌ **FAIL** |
| d63e193 | add diagnostics | ❌ FAIL |
## Conclusion
The build transitions from **PASS → FAIL** between `e64584a` (passing) and `e164ccf` (failing). This is the first commit where the failure appears, and all subsequent commits remain broken.
**Bad commit: `e164ccf` ("switch to dev")**
The commit `d63e193` inherits the failure but did not introduce it (it only "add diagnostics"). The root cause is the environment change in `e164ccf`, which likely points the build/tests at a dev configuration that breaks the working production setup established in `e64584a`.
e286ceb
JSON Schema
Structured Output
(raw) {"commit": "e286ceb"}
The bad commit is **27b5766** ("switch to dev").
The test results show a clear transition from PASS to FAIL at this commit:
- `e4498f7` → PASS
- `b0a3049` → PASS
- `27b5766` → **FAIL** ← first failing commit (introduced the bug)
- `890fe29` → FAIL (inherits the broken state)
Since `27b5766` is the first commit where the build broke, it's the one that introduced the bug.
be29d50

The bad commit is **`7ba4604`** ("switch to dev").
The test results show the transition from PASS to FAIL happens at this commit:
- `28d92af` — PASS
- `7ba4604` — **FAIL** (first failure)
- `631d036` — FAIL (inherits the broken state)
Since `7ba4604` is the first commit where the build broke, it introduced the bug.

# Bug Analysis
Looking at the test results across commits:
| Commit | Subject | Result |
|--------|---------|--------|
| de09695 | Initial commit | ✅ PASS |
| 7b57792 | setup production env | ✅ PASS |
| c01339a | switch to dev | ❌ FAIL |
| 94083f3 | add diagnostics | ❌ FAIL |
## Conclusion
The build transitions from **PASS → FAIL** at commit **`c01339a`** ("switch to dev").
- Everything up to and including `7b57792` passes.
- The failure first appears at `c01339a`, and persists into `94083f3` (which just adds diagnostics on top of an already-broken state).
## Bad Commit
**`c01339a`** — *"switch to dev"*
This is the commit that introduced the bug. It's the first commit where the tests started failing, indicating the switch to the dev environment/configuration broke the build.
f0eef9a
JSON Schema
Structured Output
(raw) {"commit": "f0eef9a"}
The bad commit is **689afc3** ("switch to dev").
- ed5131b ("Initial commit") and 63c5224 ("setup production env") both pass with exit code 0.
- 689afc3 ("switch to dev") is the first commit that fails, with exit code 1.
- b4defe9 ("add diagnostics") comes after it and also fails, which fits with it inheriting the break rather than causing it.
So 689afc3 is where the build first breaks. Its subject suggests that switching the environment to dev (probably a config or environment variable change) is the likely cause.
38a18df
JSON Schema
Structured Output
(raw) {"commit":"38a18df"}
The bad commit is **3b9b556** ("switch to dev").
- **99a2441** ("setup production env") is the last commit that passes (exit code 0).
- **3b9b556** ("switch to dev") is the first commit that fails (exit code 1).
- **7e9334a** ("add diagnostics") still fails, so the break carried forward from the commit before it.
The switch from the production environment to the dev configuration most likely introduced the build failure.
**Answer: 3b9b556**
90370d9
JSON Schema
Structured Output
(raw) {"commit":"90370d9"}
The bad commit is **8ac9a6a** ("switch to dev").
The test results show where the build first broke:
| Commit | Subject | Result |
|---|---|---|
| 7fb41ea | Initial commit | PASS |
| 8b763ee | setup production env | PASS (last good) |
| **8ac9a6a** | **switch to dev** | **FAIL (first bad)** |
| 90b3dac | add diagnostics | FAIL |
- 8b763ee passes, so everything up to and including "setup production env" is fine.
- 8ac9a6a is the first commit that fails, so "switch to dev" introduced the break.
- 90b3dac still fails because it is built on top of 8ac9a6a. It inherits the problem, so it isn't the cause. You would need to test it separately to know whether it adds problems of its own.
`git bisect` would reach the same result. To confirm and see what changed, run `git show 8ac9a6a`. The switch from the production setup to the dev setup likely changed a config value or environment variable that the build or tests depend on.
3e35309
JSON Schema
Structured Output
(raw) {"commit":"3e35309"}
The bad commit is **75cd992** ("switch to dev").
The tests pass through 050b48f ("setup production env"). They first fail at 75cd992, and the later commit 820d812 ("add diagnostics") still fails. So 75cd992 is the first bad commit.
cbcda66
JSON Schema
Structured Output
(raw) {"commit":"cbcda66"}
The bad commit is **7395cb2** ("switch to dev").
Going through the history from oldest to newest:
| Commit | Subject | Result |
|---|---|---|
| 1b42c6d | Initial commit | PASS |
| 35700c0 | setup production env | PASS (last good) |
| **7395cb2** | **switch to dev** | **FAIL (first bad)** |
| 6e3a69b | add diagnostics | FAIL |
- **7395cb2 is where the build first breaks.** Its parent, 35700c0, passes.
- **6e3a69b fails because it builds on top of 7395cb2.** Its failure is inherited, so it is not the cause.
This is the same conclusion `git bisect` would reach with 35700c0 marked good and 6e3a69b marked bad.
The commit subjects suggest the cause: the build passed with the production environment config, and switching to dev likely changed a setting the build or tests depend on. To confirm, run `git show 7395cb2` to see exactly what changed.
ec5022b
JSON Schema
Structured Output
(raw) {"commit":"ec5022b"}
**Bad commit: `9eb1eb6` — "switch to dev"**
Reasoning: The test suite passes at `20cf733` (Initial commit) and `60f3826` (setup production env), then fails starting at `9eb1eb6` and continues failing at `6cbd270`. Since `9eb1eb6` is the first commit where the build breaks — and the subsequent failure in `6cbd270` ("add diagnostics") is just the inherited breakage — `9eb1eb6` "switch to dev" is the commit that introduced the bug.
2882e84
JSON Schema
Structured Output
(raw) {"commit":"2882e84"}
**ed3bb1a** ("switch to dev")
Tests pass at `75bdf6d` and first fail at `ed3bb1a`, which remains broken in the following commit `0db3176` — so `ed3bb1a` is the commit that introduced the breakage.
edcc34a
JSON Schema
Structured Output
(raw) {"commit":"edcc34a"}
**Bad commit: `fd0b2ba` — "switch to dev"**
**Reasoning:**
Using the test results as a bisect log, the transition point from PASS to FAIL is unambiguous:
| Commit | Subject | Result |
|---|---|---|
| `41a855a` | Initial commit | PASS |
| `a395853` | setup production env | PASS |
| **`fd0b2ba`** | **switch to dev** | **FAIL ← first bad** |
| `0e65896` | add diagnostics | FAIL (inherited) |
- `41a855a` and `a395853` both build/test cleanly, so the defect was not present through "setup production env."
- `fd0b2ba` is the *first* commit where the tests fail, which by definition makes it the bug-introducing commit (equivalent to what `git bisect` would report as `fd0b2ba is the first bad commit`).
- `0e65896` ("add diagnostics") fails only because it is a descendant of `fd0b2ba` — it inherits the breakage rather than causing it. Its subject also suggests it was an attempt to investigate the already-broken state.
**Likely cause:** The commit "switch to dev" flips the environment/config from production to a dev setting (e.g., a config file, env var, dependency channel, or endpoint). Something the tests rely on — a value defined only in the production config, or a dev-only dependency/URL that isn't available in the test environment — is now missing or wrong, producing exit code 1.
**Suggested next steps:**
```bash
git show fd0b2ba # inspect the config/env changes
git revert fd0b2ba # confirm tests pass again
```
If the revert restores a green build, the diff of `fd0b2ba` pinpoints the exact setting to fix forward.
9f82add
JSON Schema
Structured Output
(raw) {"commit": "9f82add"}
**Bad commit: `4c751c9` — "switch to dev"**
Reasoning from the bisect data:
| Commit | Subject | Result |
|---|---|---|
| c95f98b | Initial commit | PASS |
| 968dccd | setup production env | PASS |
| **4c751c9** | **switch to dev** | **FAIL** ← first failure |
| 999b9f9 | add diagnostics | FAIL |
The build is healthy through `968dccd` and breaks at `4c751c9`, with the failure persisting into `999b9f9` (which only adds diagnostics and therefore just inherits the breakage). Since `4c751c9` is the earliest commit exhibiting the failure, it's the one that introduced the bug — most likely by pointing the environment/config at "dev" values that don't exist or aren't valid in the build environment.
4245c51
JSON Schema
Structured Output
(raw) {"commit":"4245c51"}
**Bad commit: `c10e928` — "switch to dev"**
### Reasoning
The test results form a clean bisect boundary:
| Commit | Subject | Result |
|--------|---------|--------|
| `cd9c59c` | Initial commit | PASS |
| `8e05073` | setup production env | PASS |
| **`c10e928`** | **switch to dev** | **FAIL** ← first failure |
| `f0f167b` | add diagnostics | FAIL |
`8e05073` is the last known-good commit, and `c10e928` is the first commit where the build breaks. Since failures persist afterward (a "sticky" regression rather than a flaky test), the defect was introduced by `c10e928`.
`f0f167b` ("add diagnostics") is a red herring — it inherits the broken state from its parent, and its name suggests it was an attempt to *investigate* the failure, not cause it. Likewise, "setup production env" still passed, so the environment scaffolding itself was fine; the regression came from the subsequent switch to the dev configuration (e.g. pointing at a dev endpoint/config/dependency that doesn't resolve in the build/test environment).
### Suggested next step
```bash
git show c10e928 # inspect the config/env change
git revert c10e928 # confirm the build goes green again
```

## Analysis
Looking at the test results from oldest to newest:
| Commit | Message | Result |
|--------|---------|--------|
| `a2464b0` | Initial commit | ✅ PASS |
| `ce83c66` | setup production env | ✅ PASS |
| `b562896` | switch to dev | ❌ FAIL |
| `cdde671` | add diagnostics | ❌ FAIL |
The build passes through `ce83c66` and first fails at `b562896`. All subsequent commits also fail, indicating the bug was introduced and never fixed.
## Answer
**`b562896`** — "switch to dev"
This commit is the first one where the build breaks. The commit subject suggests it switched the environment configuration to development, likely introducing a misconfiguration (e.g., wrong environment variables, dev-only settings that broke the build process, or an incomplete/incompatible dev configuration).

**1a15dd9** (switch to dev)
This is the first commit where the tests fail (exit code 1), after previously passing at `4da6ad3`. Since `2441a5f` also fails, but it comes after `1a15dd9` which already introduced the failure, the root cause is `1a15dd9`.

This commit is the first one where the test suite fails (exit code 1). The previous commits (`966cb30` and `512d936`) both passed, and the failure persists in the subsequent commit `fee9ec0`, confirming that `dd3f982` introduced the breaking change.
cd12e7d switch to dev
JSON Schema
Structured Output
(raw) {"commit":"cd12e7d switch to dev"}
The bad commit is the one that introduced the bug, which is the first commit where the tests fail. According to the test results, the first failure occurs at commit `f6e69e5` (subject line: "switch to dev"). Therefore, the bad commit hash is `f6e69e5`.
Answer: f6e69e5
bd9d5ac
The bad commit is d910242, as it is the first commit that caused the test to fail. The test results show that the initial two commits passed, but starting with d910242, the tests failed, indicating the bug was introduced in that commit.
The bad commit is `7ec5c15` (subject line: "switch to dev"), as it is the first commit where the tests fail.
8abc767
The bad commit is`8abc767` (subject: "switch to dev"). This is the first commit that fails the test (exit code 1), indicating it introduced the bug. Subsequent commits (`d173612 add diagnostics`) also fail, but `8abc767` is the root cause.

The first failing commit is **6beef5c** ("switch to dev").
### Reasoning:
- The oldest commit `38ff82b` ("Initial commit") passes.
- The next commit `c13f14c` ("setup production env") also passes.
- The commit `6beef5c` ("switch to dev") **fails** — this is the first failure.
- Since each commit builds on the previous one, the bug was likely introduced in `6beef5c`.
- The subsequent commit `220cda3` ("add diagnostics") also fails, but that’s likely a consequence of the earlier broken state.
Thus, the **bad commit** that broke the build is:
**6beef5c** (or "switch to dev")
07a0d58
JSON Schema
Structured Output
(raw) {
"commit": "07a0d58"
}
To identify the **bad commit**, let's analyze the information step-by-step:
### Step 1: Review the Commit History (Newest First)
- `231d5b3` — **add diagnostics** — **FAIL**
- `d6c4f2a` — **switch to dev** — **FAIL**
- `4e1b34c` — **setup production env** — **PASS**
- `0c73d4b` — **Initial commit** — **PASS**
### Step 2: Analyze Test Results
- The **last commit before the failures** (`4e1b34c`) passed.
- The next commit (`d6c4f2a`) failed.
- The commit after that (`231d5b3`) also failed.
This suggests that **the failure propagates backward from the last failing commit**.
### Step 3: Determine Which Commit Introduced the Bug
Since both `d6c4f2a` and `231d5b3` failed, but `d6c4f2a` comes before `231d5b3`, we need to check which one actually caused the failure chain.
However, since `d6c4f2a` fails and then `231d5b3` also fails, it’s likely that **the bug was introduced in `231d5b3`** because:
- It's the most recent commit before the failures.
- If `d6c4f2a` had been clean, maybe `231d5b3` would have passed.
But since both failed, and the build stopped at `d6c4f2a`, it means the **failure started with `d6c4f2a`**.
But the question asks for the **first bad commit** that broke the build. Since `d6c4f2a` is the first commit in the list that fails, **it is likely the culprit**.
### Step 4: Final Answer
The **bad commit** is:
```
d6c4f2a
```
**Answer:**
`d6c4f2a`
The first `FAIL` in the bisect is the introducer:
* **Hash:** `5ab2b8c`
* **Subject:** `switch to dev`
```
4c65456 Initial commit: PASS
00811ae setup production env: PASS <- last good
5ab2b8c switch to dev: FAIL <- first bad / BAD COMMIT
9457002 add diagnostics: FAIL
```

The bad commit is **d1a7b9c** (switch to dev).
**Reasoning:**
- `ada5038` (Initial commit): PASS ✅
- `c99353f` (setup production env): PASS ✅
- `d1a7b9c` (switch to dev): ❌ FAIL — this is the first commit where the build broke
- `0f82860` (add diagnostics): ❌ FAIL — still broken, but didn't introduce the bug
Since both prior commits passed and the build first failed at "switch to dev", that's the commit that introduced the bug.

The bad commit is: `2a01104` (or the subject line "switch to dev").

The bad commit is the first one that failed after a passing commit. The test results show that `8cbac12` (setup production env) passed, but `9f74c3c` (switch to dev) failed. Since the bug was introduced in the commit that caused the first failure, the answer is the commit hash or subject of `9f74c3c`.
9f74c3c
8f68076
JSON Schema
Structured Output
(raw) {"commit": "8f68076"}
The bad commit is **7bfa35d** (or its subject line, "switch to dev").
This is because:
- The build passes for `5e7cdde` (Initial commit) and `eb4bf6f` (setup production env).
- The build first fails at `7bfa35d` (switch to dev) and continues to fail in the next commit (`af63f62`).
- Therefore, **7bfa35d** is the commit that introduced the bug.

**Bad commit: `1c392ef`** — "switch to dev"
**Reasoning:**
- `0933f76` (Initial commit): PASS ✓
- `10b6b8c` (setup production env): PASS ✓
- `1c392ef` (switch to dev): **FAIL ✗** ← first failure
- `4428398` (add diagnostics): FAIL ✗
The build passed through `10b6b8c` and began failing at `1c392ef`. Since `4428398` ("add diagnostics") also fails but comes *after* the first failure, it didn't introduce the bug — it inherited it. Therefore, the commit that introduced the bug is **`1c392ef` (switch to dev)**.
The bad commit is **`7011965`** ("switch to dev").
Reasoning: `89e35b0` and `04344fe` both pass, while `7011965` is the first commit that fails (exit code 1). Since the failure appears at `7011965` and persists in the later commit `e5de8b3`, the bug was introduced by `7011965`.
**Bad commit: `26477d7` — "switch to dev"**
**Reasoning:**
Walking through the history chronologically:
- `3509609` (Initial commit) → PASS
- `94957b7` (setup production env) → PASS
- `26477d7` (switch to dev) → **FAIL** ← first failure
- `aecff8a` (add diagnostics) → FAIL
Since `94957b7` still passes and `26477d7` is the first commit where the build breaks, the bug was introduced in **`26477d7` ("switch to dev")**. The later commit `aecff8a` merely inherits the broken state from its parent.
A quick `git bisect` would confirm this, and you could inspect the change with `git show 26477d7` — likely the dev environment switch altered a config value, dependency version, or build flag that the production setup depended on.
**Bad commit: `0faa8fe` ("switch to dev")**
Reasoning:
- `10c318d` (Initial commit): **PASS**
- `aede06a` (setup production env): **PASS**
- `0faa8fe` (switch to dev): **FAIL** ← first failure appears here
- `90e6a09` (add diagnostics): **FAIL**
Since the build passed at `aede06a` and first failed at `0faa8fe`, the bug was introduced by commit **`0faa8fe`** ("switch to dev"). The subsequent commit `90e6a09` only inherited the broken state — it didn't introduce the bug.
**Bad commit: `a75c465` ("switch to dev")**
**Reasoning:**
- `c6fdad3` (Initial commit): **PASS** ✅
- `71e436e` (setup production env): **PASS** ✅
- `a75c465` (switch to dev): **FAIL** ❌ ← First failure
- `a5e8f42` (add diagnostics): **FAIL** ❌
Using a bisection-style analysis, the build passes at `71e436e` and first fails at `a75c465`. Since the failure appears at `a75c465` and persists in the subsequent commit (`a5e8f42`), the bug was introduced in commit **`a75c465`** ("switch to dev"). The "add diagnostics" commit merely inherited the broken state; it didn't cause it.
**Bad commit: `0eef07e` — "switch to dev"**
Reasoning: Using a binary-search (bisect) approach on the history, the first two commits pass:
- `7e53041` Initial commit: PASS
- `f0f0414` setup production env: PASS
The failure first appears at:
- `0eef07e` switch to dev: FAIL ← **first bad commit**
- `17d06dd` add diagnostics: FAIL (still broken, but it only inherits the bug)
Since `f0f0414` is good and its immediate child `0eef07e` is the first commit where the build breaks, **`0eef07e`** is the commit that introduced the bug.
The bad commit is **`770cb3f`** — **"switch to dev"**.
It's the first commit where the build starts failing: `afc97cc` still passes, `770cb3f` fails (exit code 1), and the failure persists in the later commit `2d3295d`.
**Bad commit: `8782079` — "switch to dev"**
**Reasoning:**
Bisecting the history from oldest to newest:
| Commit | Subject | Result |
|--------|---------|--------|
| bf1e307 | Initial commit | ✅ PASS |
| 6684061 | setup production env | ✅ PASS |
| **8782079** | **switch to dev** | ❌ **FAIL** ← first failure |
| 790f301 | add diagnostics | ❌ FAIL (inherits the bug) |
The build passes at `6684061` and fails for the first time at `8782079`. Since `790f301` ("add diagnostics") builds on top of the already-broken state, it fails too — but the bug was introduced by **`8782079`**, the commit that switched the environment configuration from production to dev.
**Bad commit: `2494d96` — "switch to dev"**
**Reasoning:**
- `cc21ca8` (Initial commit) → PASS
- `03492c0` (setup production env) → PASS
- `2494d96` (switch to dev) → **FAIL** ← first failing commit
- `40eb6ca` (add diagnostics) → FAIL
Since `03492c0` passes and `2494d96` is the first commit where the build breaks, the bug was introduced in `2494d96` ("switch to dev"). The subsequent commit `40eb6ca` fails only because it inherits the broken state.
**Bad commit: `50625f9` — "switch to dev"**
**Reasoning:**
- `f426d23` (Initial commit) — PASS ✅
- `e5406d4` (setup production env) — PASS ✅
- `50625f9` (switch to dev) — **FAIL ❌** ← first failure
- `d31b6ba` (add diagnostics) — FAIL ❌
Since the build passed at `e5406d4` and first broke at `50625f9`, the bug was introduced by **"switch to dev"** (`50625f9`). The subsequent commit `d31b6ba` still fails, but it only inherited the broken state rather than causing it.

We are given the git commit history from newest to oldest:
- 65656cd: add diagnostics
- e937059: switch to dev
- f5b2322: setup production env
- 47acdd8: Initial commit
And test results from oldest to newest:
- 47acdd8: PASS
- f5b2322: PASS
- e937059: FAIL
- 65656cd: FAIL
We are to find the **first bad commit** — the one that introduced the bug, such that all commits after it (newer) are bad, and all before it (older) are good.
Let’s map the commits in chronological order (oldest to newest):
1. 47acdd8: Initial commit → PASS
2. f5b2322: setup production env → PASS
3. e937059: switch to dev → FAIL
4. 65656cd: add diagnostics → FAIL
Now, we look for the first commit where the test fails, and all subsequent commits also fail.
- Commit 47acdd8: PASS → good
- Commit f5b2322: PASS → good
- Commit e937059: FAIL → this is the first failure
- Commit 65656cd: FAIL → still bad, as expected
Since the test passes at f5b2322 and fails at e937059, the bug was introduced in commit **e937059**.
We are asked to return either the first 7 characters of the hash or the commit subject line.
The hash is already given as 7 characters: `e937059`
The subject line is: `switch to dev`
Either is acceptable, but since the examples in the prompt show the hash format (e.g., 'abc1234'), and the question says "first 7 characters", we should output the hash.
However, the instruction says: "Your answer should be the commit hash (e.g., 'abc1234') or the commit subject line."
So both are valid, but to be precise and match the example format, we'll output the hash.
But let’s double-check: is there any chance the bug was introduced earlier?
- 47acdd8: PASS
- f5b2322: PASS → so the environment setup is good
- Then e937059: switch to dev → FAIL
- Then 65656cd: add diagnostics → FAIL (likely because it’s building on the broken state)
So the root cause is in `e937059: switch to dev`.
Thus, the bad commit is **e937059**.

The bad commit is **5ddda87** (switch to dev). This is the first commit in the test history (oldest to newest) where the build fails, indicating that the bug was introduced in this commit. Subsequent commits (including `add diagnostics`) also fail, but no commits after them pass to confirm further changes. Git bisect logic would identify the earliest commit causing the failure as the culprit.

To identify the bad commit that broke the build, we analyze the git history and test results using a binary search approach with `git bisect`.
The git history (newest first) is:
```
c1952d8 add diagnostics
8e8513b switch to dev
1f2a2eb setup production env
4039640 Initial commit
```
Test results (oldest first):
```
4039640 Initial commit: PASS (exit code 0)
1f2a2eb setup production env: PASS (exit code 0)
8e8513b switch to dev: FAIL (exit code 1)
c1952d8 add diagnostics: FAIL (exit code 1)
```
Using `git bisect`:
1. Start with `git bisect start`, then mark `c1952d8` as bad (fails) and `4039640` as good (passes).
2. Git checks out `1f2a2eb`, which passes. Mark it as good.
3. The next bisect step points to `8e8513b`. Testing confirms it fails. Mark it as bad.
4. Git now identifies `8e8513b` as the first bad commit since it's between the known good (`1f2a2eb`) and bad (`c1952d8`) commits.
The bad commit is `8e8513b` ("switch to dev").
**Answer:** `8e8513b`

The bad commit that introduced the bug is **7261706**, as it is the first commit where the test results transitioned from passing (ef9dc53) to failing (7261706, 00db12a). Since subsequent commits (including 00db12a) continue to fail, the root cause lies in the "switch to dev" commit.
**Answer:** 7261706
f5fb796
JSON Schema
Structured Output
(raw) {"commit": "f5fb796"}
The bad commit is **2962f59**.
**Reasoning:**
- The test results show that the build passed for commits `18bbb84` and `7fce0b3`, but failed starting at `2962f59`.
- Since `2962f59` is the first commit where the tests failed, it is the one that introduced the bug. Subsequent commits (e.g., `182de01`) inherit the failure.
Commit hash: `2962f59`

JSON Schema
Structured Output
(raw) {"commit": "e78335b"}
Based on the test results, I can see that:
- Commit `c45581a` (Initial commit): PASS
- Commit `e07a060` (setup production env): PASS
- Commit `d47b5c2` (switch to dev): FAIL
- Commit `43a4bfd` (add diagnostics): FAIL
The tests were passing up to and including `e07a060`, but failed starting with `d47b5c2`. This indicates that commit `d47b5c2` ("switch to dev") introduced the bug.
**Answer: d47b5c2**
9b5588a
JSON Schema
Structured Output
(raw) {"commit": "9b5588a"}
Based on the test results, I can see that:
1. Commit 3e6a018 (Initial commit): PASS
2. Commit d49a1ca (setup production env): PASS
3. Commit 5fed60e (switch to dev): FAIL
4. Commit 630d25e (add diagnostics): FAIL
The tests pass up to and including commit d49a1ca, but fail starting with commit 5fed60e. This means the bug was introduced in commit 5fed60e.
**Bad commit: 5fed60e** (or "switch to dev")
f61e086
JSON Schema
Structured Output
(raw) {"commit": "f61e086"}
Based on the test results, I can see that:
- Commits 6e32137 (Initial commit) and 1d9851d (setup production env) both PASS
- Commit 4d7957e (switch to dev) FAILS
- Commit 7e5b2a4 (add diagnostics) also FAILS
The bug was introduced in commit **4d7957e** ("switch to dev"), as this is the first commit where the tests start failing. The subsequent commit 7e5b2a4 just inherited the broken state.
**Bad commit: 4d7957e**
f25654e
JSON Schema
Structured Output
(raw) {"commit":"f25654e"}
Looking at the test results, I can see when each commit was introduced:
- f67aa35 Initial commit: PASS
- 950e398 setup production env: PASS
- 4626694 switch to dev: FAIL
- e4281a3 add diagnostics: FAIL
The build was passing after commit 950e398, but then failed at commit 4626694. This means commit 4626694 "switch to dev" introduced the bug. The subsequent commit e4281a3 "add diagnostics" also fails, but that's because it's built on top of the already broken commit.
**Answer: 4626694**
b0ef957
JSON Schema
Structured Output
(raw) {"commit": "b0ef957"}
Looking at the test results chronologically:
1. **cc4dcec** (Initial commit): PASS
2. **92a0aad** (setup production env): PASS
3. **21c7a34** (switch to dev): FAIL ← **This is where the build first broke**
4. **77aca30** (add diagnostics): FAIL
The build was passing up to commit `92a0aad`, but failed starting with commit `21c7a34`. This indicates that commit introduced the bug.
**Bad commit: 21c7a34** (or "switch to dev")
89e8a2c
JSON Schema
Structured Output
(raw) {"commit": "89e8a2c"}
The bad commit is **0f6ce30** (subject line: "switch to dev").
This is determined by the test results: both `de93303` (Initial commit) and `5c6ac27` (setup production env) PASS, but the very next commit `0f6ce30` (switch to dev) FAILs, and it remains broken through `0568364` (add diagnostics). Therefore, the bug was introduced by commit `0f6ce30`.
93512f9
JSON Schema
Structured Output
(raw)
{
"commit": "93512f9"
}
The bad commit is **8ea75e7** with the subject line **"switch to dev"**.
**Reasoning:**
Looking at the test results in chronological order:
| Commit | Subject | Result |
|--------|---------|--------|
| 4f244dd | Initial commit | ✅ PASS |
| 46feac6 | setup production env | ✅ PASS |
| **8ea75e7** | **switch to dev** | ❌ **FAIL** |
| 0489d2f | add diagnostics | ❌ FAIL |
The transition from PASS → FAIL first occurs at **8ea75e7 "switch to dev"**, meaning this commit introduced the bug that broke the build. The subsequent commit "add diagnostics" continues to fail, which is consistent (you're debugging the code, not fixing it).

8f227af
0beb6a0
JSON Schema
Structured Output

{"commit":"0beb6a0"}
The bad commit is **cbd5a7b** (switch to dev).
**Reasoning:** The test results show a clear transition from passing to failing:
| Commit | Subject | Result |
|--------|---------|--------|
| ab36f1e | Initial commit | ✅ PASS |
| 988b44c | setup production env | ✅ PASS |
| **cbd5a7b** | **switch to dev** | **❌ FAIL** |
| f6a0ab9 | add diagnostics | ❌ FAIL |
Since `988b44c` (setup production env) passes but the next commit `cbd5a7b` (switch to dev) fails, the bug was introduced by the **"switch to dev"** commit.

Based on the test results, the build passed on commit `e3e3324` but failed on the next commit, `3553855`. Therefore, the commit that introduced the bug is:
**3553855** (or "switch to dev")
54f6514
The bad commit is **d545e41**.
Looking at the test results chronologically:
- `7c51aa0` Initial commit → **PASS**
- `f104fa3` setup production env → **PASS**
- `d545e41` switch to dev → **FAIL** ← *first failure*
- `242ee81` add diagnostics → **FAIL**
The build transitioned from PASS to FAIL at commit **d545e41** ("switch to dev"), making it the commit that introduced the bug.
Based on the test results, the build was passing at commit `eca23ad` and first failed at commit `9a40fd4`. Since `9a40fd4` is the first commit to introduce the failure (transitioning from PASS to FAIL), it is the bad commit.
**9a40fd4**
Based on the test results, the build was passing up until the commit `bdb01ff setup production env`. The very next commit, **3653575** ("switch to dev"), is the first one to fail (exit code 1).
Therefore, the bad commit that introduced the bug is:
**3653575**
The bad commit is **261b3a1** ("switch to dev").
**Reasoning:** Looking at the test results from oldest to newest:
- `dee1406` Initial commit: **PASS**
- `ff8fb30` setup production env: **PASS**
- `261b3a1` switch to dev: **FAIL** ← Bug introduced here
- `1c3b14b` add diagnostics: **FAIL** (inherited from previous)
The transition from PASS to FAIL occurs at commit `261b3a1`, making it the first bad commit that broke the build.
The bad commit that broke the build is **0f7c673** ("switch to dev").
Here's the reasoning:
- `d71d653` Initial commit → **PASS** ✅
- `8b541f3` setup production env → **PASS** ✅
- `0f7c673` switch to dev → **FAIL** ❌ ← First failure
- `903201d` add diagnostics → **FAIL** ❌
The commit `0f7c673` is where the transition from PASS to FAIL occurs, meaning "switch to dev" introduced the bug.
The bad commit is **`ffde51d`** ("switch to dev").
This is the first commit where the test transitions from PASS to FAIL. The previous commit (`b396cae`) passed, so `ffde51d` is where the build was broken.
9243508
The bad commit is **0fd5582** (`switch to dev`).
The last passing commit was `97d9a99 setup production env`, and the very next commit `0fd5582 switch to dev` is where the build first fails (exit code 1). This means `0fd5582` is the commit that introduced the bug.

Since `fe54e2b` (add diagnostics) also fails, but it comes *after* `a6e1eac`, the regression was introduced at `a6e1eac` — the first commit where the test transitioned from PASS to FAIL.

**Bad commit: `6956583` — "switch to dev"**
Reasoning:
- `2d062c8` (Initial commit): PASS
- `8ee2c68` (setup production env): PASS
- `6956583` (switch to dev): **FAIL** ← first failure
- `4fd0bb0` (add diagnostics): FAIL
Since the build passed at `8ee2c68` and first failed at `6956583`, the bug was introduced by commit `6956583` ("switch to dev"). This is exactly what `git bisect` would identify as the first bad commit — all commits before it are good, and all commits after it inherit the failure.
**7322df3** ("switch to dev") is the bad commit — it's the first commit where the test suite fails, meaning the bug was introduced there.
**Bad commit: `b29b56b` — "switch to dev"**
Reasoning:
- `2a429ba` (Initial commit): PASS
- `d4cb3a1` (setup production env): PASS — last known good commit
- `b29b56b` (switch to dev): FAIL — first failing commit
- `8178275` (add diagnostics): FAIL — failure persists after
Since `d4cb3a1` passed and `b29b56b` was the first commit to fail, `b29b56b` is the commit that introduced the bug. This mirrors what `git bisect` would identify as the first bad commit.

The bisect-like results show that 5837ada and b6c7a5b both pass, while cd28791 is the first commit that fails. Therefore cd28791 ("switch to dev") is the commit that introduced the bug.

20517a1
JSON Schema

(raw) {"commit":"20517a1"}
The test results show a clean pass on the two oldest commits (d42578b and 5060d32). The first failure appears exactly on f276835; the newest commit (1226004) also fails, but that is simply because the bug was already present.
Consequently the single commit that introduced the regression is the one whose subject line is “switch to dev” and whose abbreviated hash is f276835.

**b5607bd** — "switch to dev"
Reasoning: This is the first commit where the test output changes from PASS (exit code 0) to FAIL (exit code 1). Commits `6e0ea7a` and `4ea5e97` both pass, and the failure begins with `b5607bd`. The subsequent commit `edae440` also fails, but it was added *after* the bug was introduced, so it is not the culprit.
989ca21
JSON Schema
Structured Output
(raw) {"commit":"989ca21"}
**b62f6d9** ("switch to dev")
Reasoning: Using a bisect-style analysis of the test results, the build passed at `0fb971f` and first failed at `b62f6d9`. Since `0fb971f` (the parent) passed and `b62f6d9` is the first commit that introduced the failure, that is the bad commit. The subsequent commit `7dc0524` also fails, meaning it did not fix the issue introduced by `b62f6d9`.
9ac6696
JSON Schema
Structured Output
(raw) {"commit": "9ac6696"}
**431b41b** — "switch to dev"
**Reasoning:**
- `4bb251a` (Initial commit): PASS
- `b25c9f9` (setup production env): PASS
- `431b41b` (switch to dev): **FAIL** ← first failure
- `89469e9` (add diagnostics): FAIL (still broken)
The build was passing before `431b41b` and started failing at that commit, so it's the one that introduced the bug. The subsequent commit (`89469e9`) only added diagnostics without fixing the issue, which is why the failure persists.
943193b
JSON Schema
Structured Output
(raw) {"commit":"943193b"}
**dfecd11** — `switch to dev`
**Reasoning:** Walking the history from oldest to newest, the first commit where the test output changes from PASS to FAIL is `dfecd11` (`switch to dev`):
- `d8c339b` Initial commit → PASS
- `20f3ba3` setup production env → PASS
- `dfecd11` switch to dev → **FAIL** ← first failure
- `6bc980f` add diagnostics → FAIL (still broken)
Since `20f3ba3` still passed and the build broke immediately after `dfecd11`, that commit introduced the bug. The subsequent commit (`6bc980f`, "add diagnostics") only attempted to debug the issue — it did not introduce it.

**1513179** (or **"switch to dev"**)
The tests passed at commit `263bcba`, and the first commit to produce a failing test is `1513179`. Since `1d899da` merely added diagnostics (and still fails), the commit that actually introduced the bug is `1513179`.
8549753
JSON Schema
Structured Output
(raw) {"commit":"8549753"}
**8a2f0a6** (commit subject: "switch to dev")

## Bisecting the Build Failure
Looking at the test results in chronological order, I can identify where the state transitions from passing to failing:
| Order | Commit | Subject | Result |
|-------|--------|---------|--------|
| 1 | `8229bba` | Initial commit | ✅ PASS |
| 2 | `e2e5753` | setup production env | ✅ PASS |
| 3 | `43b9770` | switch to dev | ❌ FAIL |
| 4 | `aaeca47` | add diagnostics | ❌ FAIL |
The key insight: `e2e5753` is the **last commit that passed**, and `43b9770` is the **first commit that failed**. Since `aaeca47` ("add diagnostics") also fails, the bug was introduced *before* it — the diagnostics commit may even be an attempt to debug the problem caused by the earlier commit.
**The bad commit is:**
> **`43b9770` — "switch to dev"**
bad904c (switch to dev)
JSON Schema
Structured Output
(raw) {"commit": "bad904c (switch to dev)"}
**eae4c86** (switch to dev)
**Reasoning:**
Looking at the test results in chronological order:
| Commit | Subject | Test Result |
|--------|---------|-------------|
| 72acb5c | Initial commit | ✅ PASS |
| b39a820 | setup production env | ✅ PASS |
| **eae4c86** | **switch to dev** | ❌ **FAIL** |
| 08e73f9 | add diagnostics | ❌ FAIL |
The tests were passing after `b39a820` and first failed at `eae4c86`. Since `08e73f9` ("add diagnostics") was added afterward, it likely just added diagnostics to help *debug* the already-broken state — it didn't introduce the failure. The transition from PASS → FAIL happens exactly at `eae4c86`, making **eae4c86 ("switch to dev")** the commit that introduced the bug.
8e97cb0
JSON Schema
Structured Output
(raw) { "commit": "8e97cb0" }
## Reasoning
**Step 1: Establish the baseline.** The oldest commit `50bbe32` (Initial commit) passes. So the bug is not pre-existing in the repository's history.
**Step 2: Find the transition point from PASS → FAIL.**
| Commit | Result | Interpretation |
|---|---|---|
| `50bbe32` Initial commit | PASS | Good |
| `bbc1b4a` setup production env | PASS | Good — this commit still builds |
| `9f78c47` switch to dev | **FAIL** | **First failure — regression introduced here** |
| `7fc1b98` add diagnostics | FAIL | Still failing (inherited from `9f78c47`) |
**Step 3: Apply the standard bisection rule.** The bad commit is the *oldest* commit that fails, given its parent passed. That's exactly `9f78c47`, since:
- Its parent `bbc1b4a` passes → the bug was introduced in the diff of `9f78c47` (the "switch to dev" change, likely a dev-mode config, wrong environment flag, or dev build path).
- The newest commit `7fc1b98` also fails, but it cannot be the culprit: the build was **already broken** before it ("add diagnostics"). It merely propagates the failure (and its diagnostics presumably just report on it).
So `7fc1b98` is a "symptom" commit, not the cause. Bisecting would land on `9f78c47`.
## Final Answer
**9f78c47** ("switch to dev")
b133145 (switch to dev)
JSON Schema
Structured Output
(raw) {"commit": "b133145 (switch to dev)"}
## Analysis
Looking at the test results in order (oldest → newest):
| Commit | Subject | Result |
|---|---|---|
| 1d8012e | Initial commit | ✅ PASS |
| e5e53de | setup production env | ✅ PASS |
| **24a9d91** | **switch to dev** | ❌ **FAIL** |
| bd26de2 | add diagnostics | ❌ FAIL |
The build passes at `e5e53de` and first breaks at `24a9d91`. The later commit `bd26de2` also fails, but that's just inheriting the broken state (its "diagnostics" presumably are there to help debug it).
The first commit that turns a passing build into a failing one is the culprit.
## Answer
**24a9d91** (subject: `switch to dev`)
682deaf switch to dev
JSON Schema
Structured Output
(raw) {"commit":"682deaf switch to dev"}
**`2782c7f`** (commit subject: `switch to dev`)
**Reasoning:**
Looking at the test results in chronological (oldest first) order, we can identify where the build first breaks:
| Commit | Subject | Result |
|--------|---------|--------|
| `dddee8d` | Initial commit | PASS |
| `0690bb9` | setup production env | PASS |
| `2782c7f` | switch to dev | **FAIL** ← first failure |
| `b2ef3b7` | add diagnostics | FAIL |
Since `0690bb9` is the last commit that passed and `2782c7f` is the first that failed, the bug was introduced in `2782c7f`. The subsequent commit (`b2ef3b7`) still fails because it is built on top of the already-broken `2782c7f`.

## Answer
The bad commit is **4b64f39** — *"switch to dev"*
## Reasoning
Looking at the test results chronologically:
| Commit | Subject | Result |
|--------|---------|--------|
| c5246c0 | Initial commit | ✅ PASS (exit 0) |
| 413c92f | setup production env | ✅ PASS (exit 0) |
| **4b64f39** | **switch to dev** | ❌ **FAIL (exit 1)** |
| a1b149c | add diagnostics | ❌ FAIL (exit 1) |
This is a classic `git bisect` scenario. The build was passing at `413c92f` and failing at `4b64f39`, so the bug was introduced by `4b64f39` ("switch to dev"). All subsequent commits (`a1b149c`) fail too, since they inherit the broken state — they didn't *introduce* the bug, they just inherited it.
You could find this with:
```bash
git bisect start 4b64f39 413c92f # bad, good
# or simply check the commit directly:
git checkout 4b64f39 && npm test # fails here
```
b542912
JSON Schema
Structured Output
(raw) { "commit": "b542912" }
The bad commit is **c80cec3** ("switch to dev") — the first commit where the test fails.
**Bad commit: `db4b1a1` — "switch to dev"**
**Reasoning:**
Using a bisect-style analysis, we look for the first commit where the build transitions from PASS to FAIL:
| Commit (oldest → newest) | Result | Status |
|---|---|---|
| `e54a35e` Initial commit | PASS (exit 0) | good |
| `dcd9f99` setup production env | PASS (exit 0) | good |
| `db4b1a1` switch to dev | FAIL (exit 1) | **bad — first failure** |
| `1d91272` add diagnostics | FAIL (exit 1) | bad (bug still present) |
Since `dcd9f99` passes and its immediate child `db4b1a1` fails, the bug was introduced by **`db4b1a1` ("switch to dev")**. The subsequent commit `1d91272` also failing is consistent — the regression persisted rather than being introduced anew.
0600eec switch to dev
JSON Schema
Structured Output
(raw) { "commit": "0600eec switch to dev" }
**857f70a** ("switch to dev") — it's the first commit where the build fails, so it introduced the bug.

(raw) {"commit":"cf892c7"}
# Bad Commit Identified
## Answer: `6c55135` — "switch to dev"
## Reasoning
This is a classic **git bisect** scenario. Using the test results to find where the build transitioned from PASS to FAIL:
| Commit (oldest → newest) | Subject | Result |
|---|---|---|
| `18728cc` | Initial commit | ✅ PASS |
| `39099d1` | setup production env | ✅ PASS |
| `6c55135` | switch to dev | ❌ **FAIL** ← first failure |
| `a773dfe` | add diagnostics | ❌ FAIL |
The last known-good commit is `39099d1` ("setup production env"), and the first commit that fails the tests is **`6c55135` ("switch to dev")**.
While `a773dfe` ("add diagnostics") also fails, it's not the culprit — it simply inherited the broken state from the earlier commit. The bug was introduced by `6c55135`, likely because switching to a dev environment configuration broke the build (e.g., missing dependencies, different config values, or an unstable environment).
## Verification (as git bisect would report)
```
git bisect start
git bisect bad a773dfe
git bisect good 39099d1
# Bisecting: testing 6c55135 — switch to dev → FAIL
6c55135 is the first bad commit
```

Invalid JSON. Output: To identify the **bad commit**, let's analyze the information step-by-step:
### Step 1: Review Commit History (Newest First)
- `8468041` — last commit
- `5a10d38` — next
- `9d3e0fa` — next
- `d99fef8` — oldest
### Step 2: Review Test Results (Oldest First)
- `d99fef8` — PASS
- `9d3e0fa` — PASS
- `5a10d38` — FAIL
- `8468041` — FAIL
### Step 3: Determine Which Commit Broke the Build
The **build failed** at commits with exit code 1:
- `5a10d38` (switch to dev) → FAIL
- `8468041` (add diagnostics) → FAIL
Since the **last commit before the failure chain** is `5a10d38`, but it's not the earliest failing commit. However, since both `5a10d38` and `8468041` fail, we need to find which one actually caused the break.
But in most cases, if a later commit fails, it may depend on dependencies. However, since `5a10d38` comes before `8468041`, and both fail, the **earliest failing commit** is `5a10d38`.
However, **if the build process runs all commits in order**, then the **first failing commit** (`5a10d38`) would be the culprit.
### Step 4: Conclusion
The **bad commit** is the one that caused the first failure when building from the beginning. That is:
```
5a10d38
```
---
**Final Answer:**
`5a10d38`

Invalid JSON. Output: **a3066a5** ("switch to dev") is the bad commit.
It's the first commit in the history where tests fail — the previous commit (68a8aba "setup production env") passed with exit code 0, and a3066a5 fails with exit code 1, meaning it introduced the bug. The failure then persists through 2b6f57b.

Reasoning (binary search / bisect logic):
- `824e8db` "Initial commit" → PASS ✅
- `7b8b69d` "setup production env" → PASS ✅
- `589f4c5` "switch to dev" → **FAIL** ❌ ← first failing commit

Since all tests pass at `7b8b69d` and the failure first appears at `589f4c5`, that is the commit that introduced the break.

Reasoning: The build passed at 532276e and failed at 7564e5b, so the bug was introduced by the first commit where the tests fail — a classic bisect conclusion. The later failure at 1023fbd is just inherited from it.
