- `stops_at_boundary` — generation did not run past <tool_call|> into <|tool_response>. Per the Gemma 4 prompt-formatting spec, the model is only responsible for the call up to <tool_call|>; <|tool_response> is appended by the application with the real tool result, and is registered as an additional stop sequence purely as a backstop. This harness configures no such stop, so unconstrained runs free-run past the boundary into engine-owned territory, while required-mode grammar ends the call cleanly at an accept state.

<|channel>thought
The user wants to compare the weather in Seoul and Busan in Celsius, one city at a time.
After getting both temperatures, the user specifically requested to convert Seoul's temperature to Fahrenheit using the `convert_temperature` tool before providing the final answer.
1. **Seoul Weather (Celsius):** Already retrieved: 3°C.
2. **Busan Weather (Celsius):** Already retrieved: 8°C.
3. **Convert Seoul's temperature to Fahrenheit:** I need to call `convert_temperature` with `value=3`, `from_unit="celsius"`, and `to_unit="fahrenheit"`.
After this conversion, I will present the comparison and the converted temperature.
**Plan:**
1. Use the result from the previous calls (Seoul: 3°C, Busan: 8°C).
2. Call `convert_temperature` for Seoul (3°C to Fahrenheit).
3. Synthesize the final answer.<channel|><|tool_call>call:convert_temperature{
value:3,
from_unit:<|"|>celsiu
```
**B. multiturn-thinking / constrained #1** — PASS ✅
```
<|channel>thought
The user wants me to perform three main tasks:
1. Get the current weather in Seoul in Celsius. (Done)
2. Get the current weather in Busan in Celsius. (Done)
3. Convert Seoul's temperature from Celsius to Fahrenheit using the `convert_temperature` tool.
4. Compare the weather for both cities and present the final answer, including the conversion result.
From the previous steps, I have:
* Seoul weather: 3°C and sunny.
* Busan weather: 8°C and cloudy.
Now I need to call the `convert_temperature` tool for Seoul's temperature (3°C to Fahrenheit).
After that, I will compile all the information to answer the user's request.<channel|><|tool_call>call:convert_temperature{
value:3,
from_unit:<|"|>celsius<|"|>,
to_unit:<|"|>fahrenheit<|"|>
}<tool_call|>
```

<|channel>thought
The user wants to compare the current weather in Seoul and Busan in Celsius, one city at a time.
After getting both, the user wants to convert Seoul's temperature to Fahrenheit using the `convert_temperature` tool before providing the final answer.
1. **Get Seoul's weather in Celsius:** This has been done. The result is: `{"temp_c": 3, "condition": "sunny", "humidity": 41}`.
2. **Get Busan's weather in Celsius:** This has been done. The result is: `{"temp_c": 8, "condition": "cloudy", "humidity": 63}`.
3. **Convert Seoul's temperature to Fahrenheit:** I need to use the `convert_temperature` tool with the Seoul temperature (3°C) from Celsius to Fahrenheit.
Now I will execute the conversion call.
After that, I will compile all the information to answer the user's request.<channel|><|tool_call>call:convert_temperature{value:3,from_unit:<|"|>celsius<|"|>,to_unit:<|"|>f

The user wants to:
1. Get the current weather in Seoul in Celsius. (Done)
2. Get the current weather in Busan in Celsius. (Done)
3. Convert Seoul's temperature from Celsius to Fahrenheit using the `convert_temperature` tool. (Pending)
4. Compare the weather, presenting the results one city at a time, and including the conversion.
I have the following information:
* Seoul weather: 3°C, sunny, 41% humidity.
* Busan weather: 8°C, cloudy, 63% humidity.
Now I need to call `convert_temperature` for Seoul's temperature (3°C to Fahrenheit).
