Is there any kind of ambiguity or lack of context? or any part of the instruction already complete? 

what was previous in the code ? and what minimal changes required to meet the instruction?

give solution in short then. with mentioning code change. 

if needed re-evaluate the instruction.

### Batch re-write or in progress issue
662517 - updated to completed (changed by p-coding robot batch-rewrite issue)
63010, 660277 - Seems those were already completed, don't know why these are marked as IN PROGRESS
666281 - Updated to Completed (this was previously claimed by sazin)
669637 - completed now. (claimed by unknown)
662199, 662050, 662472, 661988 - already completed and no issue (changed by p-coding robot batch-rewrite issue)

Evaluate as an SQA Engineer
### Judge the instruction

✅ Good: none of the below options match

⛔️ Ambiguous: there are multiple interpretations of what the user wants
ℹ️ The instruction may have some ambiguity that could be resolved by common sense like assuming specific constant values

⛔️ Lack of context: ask to use something that is not presented in original code
ℹ️ Adding import of some common library is allowed, it's not lack of context
If a linked resource (file / url) is required for understanding / completing the task but its content is not provided within the instruction it’s “Lack of context”

⛔️ Non-solvable

- The task doesn’t make sense
- The task is clear but it’s impossible to solve it
- What’s asked is already implemented in the source file, even if **partially**
- Contains language different from English (meaning human languages, not a programming ones), even if for part of the instruction
Temporary: if the solution adds a comment that is not in English, then mark the instruction as non-solvable and write a comment “Solution added a non English comment.” This is very rare and is currently a temporary solution; in future we will add a non valid task label or something similar.
It is allowed to mark the instruction as non solvable in case there are comments in the code in non English language that prevent understanding of the relevant parts of source code.


### Additional
Q: Instruction asks for a function in the interface or in the header file, describes what
it shall do. Is it ok? Shall the solution and the plan actually be planning/writing the
implementation or only declare the function?
A: It is ok in case the instruction does not explicitly ask to write the implementation.
Then it is only about declaring, and the description is given to figure out the function
name and the signature. Plan shall not contain steps about actual implementation -
only about the declaration. And the solution should only declare the function.
Also, for header files there are some cases when functions in them can have
implementation and if it is one of such cases, plan and solution can have actual
implementation too.



The scratchpad is bad because it includes a testing step that requires external actions beyond code modifications, such as opening a terminal and running a command. According to the criteria, a good scratchpad should focus only on essential code changes and relevant explanations. 

### scratchpad
// Rename the momentum_optimizer struct to nesterov_optimizer
struct nesterov_optimizer {
// …
};

// Update the constructor’s name
explicit nesterov_optimizer(value_type learning_rate = 0.01) : learning_rate_(learning_rate) {}

// Modify the operator() function to be non-const
void operator()(Weigth& W, const Weigth& dW) {
auto& dW_previous = cache_.template get<0>(W);
// …
}

// Remove the mutable keyword from the optimizer_cache member variable
optimizer_cache<1, Weigth, Weigth> cache_;

✅ Good: meets the requirements

⛔️ Bad: does not meet the requirements
Please leave a comment about the reasons for the choice

### Justification criteria of Scratchpad

ℹ️ Good scratchpad contains a concise solution to the given task, it reflects only essential steps and code modifications needed to accomplish the task’s requirements. A correct scratchpad is both complete and not excessive in relation to the provided code and task; it includes all required steps and doesn't have redundant or excessive ones.

Also:

Should be relevant to the provided code and task.
Should be accurate, with steps that are technically correct and implementable.
Should be complete, mentioning all steps needed to effectively complete the required task.
Should not include unnecessary code, such as duplicate or excessive code blocks that do not contribute to solving the task or code without which the solution still works.
Should be aligned with the code's style and structure, reflecting the way the code is organized and written.
Scratchpad steps should mostly imply code changes, but may also include concise comments and explanations of how the new changes in code work.
Evaluate the scratchpad

✅ Good: meets the requirements

⛔️ Bad: does not meet the requirements
Please leave a comment about the reasons for the choice


### Additional 
Method Naming: If the method name where changes should occur is explicitly stated in the instruction but not in the plan, and the plan only describes changes within this method, the plan is not considered bad.
Bug Fixes: If the instruction asks for a bug fix and the plan includes a step explaining the cause of the bug, this is not a redundant step and is a correct plan.
Mental steps: Steps like "Test the function with various inputs to ensure correct behavior" are acceptable. However, if a plan includes actions like "run tests," "execute tests," "run in terminal," or "launch application," “Save” these are not mental steps and should be marked as a bad plan.

Plan / Solution. Q: Instruction asks to modify a code in a way that will break it (e.g. remove imports that are used without specifying what to do with code that uses those imports), shall plan and solution work on the code that will break even if it wasn’t asked by the user and for example remove or adjust those uses of imports?
A: Yes, plan and solution are good if they adjust the code accordingly and don’t let it break. Otherwise it is a bad plan and solution.

- Solution should be relevant to the instruction and plan in such priority.
- Solution should not include any changes that are not implied by the task such as changing the code style, removing the import, adding the comments in the code locations that are not mentioned in the task.
- Solutions should not be unnecessarily complicated or introduce any redundancy. For example, if the instruction asks for changing some constant like “add 10 more random strings to list X” it should generate a new code with a new definition of the list instead of e.g. generating a new function that does so.
- Solution needs to be executable in a sense that an expert after an eye-check doesn’t see reasons why it may fail to run

Plan / Solution. Q: Instruction asks to modify a code in a way that will break it (e.g. remove imports that are used without specifying what to do with code that uses those imports), shall plan and solution work on the code that will break even if it wasn’t asked by the user and for example remove or adjust those uses of imports?
A: Yes, plan and solution are good if they adjust the code accordingly and don’t let it break. Otherwise it is a bad plan and solution.

    

Is correct? (Solves the task described in the instruction and doesn’t have unnecessary steps and code looks executable)

✅ Yes

⛔️ No
Clarification of why the solution is incorrect (or the opposite) when the decision is not obvious


Has code smell is only available if the solution is good. and easily fixable when bad. 

Has code smell?
○ if a solution contains code smells like weird or redundant constructions, strange
variable names are suggested, newlines are added.
○ Applicable only to correct solutions
○ Other Comments in the code can only affect the “code smell” aspect of the answer. If
you think comments are bad and misleading — state that there is code smell and
provide a comment.
○ [optional] Comment


ℹ️ Is easily fixable
○ Can you make the code satisfy instructions either changing a single line or moving a
single code block to a different location or returning deleted single block of code?
These are the only possible options when the error is with code, not with comment.
And the change should take less than a minute to implement.
○ If instructions explicitly asked for comment (docstring for example), and it was not
present in the solution, then the solution is incorrect, but easily fixable.
○ So it’s easy fixable if (only one shall apply):
■ You have to change single line
■ Move block of code (few consecutive lines) to another location or restore
them if the block was deleted
■ Fix is related only to the comment, not to the code
○ Applicable only to incorrect solutions
○ [optional] Comment. If any clarification is needed




### 
The instruction "Update the getTermIdOrNull condition" is ⛔️ Ambiguous because it lacks specificity about which condition to update and how. The getTermIdOrNull method contains multiple conditions, including checks for curie.isPresent() and wantedTermIdPrefixes. Without clarifying which condition should be modified or what the desired outcome is, there are multiple possible interpretations of the requested change. To be actionable, the instruction needs to specify the target condition and the nature of the update required.

The solution is easily fixable by removing a single line.

The provided solution for the `create` function incorrectly hardcoded the `force` parameter as `false` in the `RoleSettings.forService` call. To align with the instruction and maintain consistent behavior, the `force` parameter that is passed to the `create` function should be used instead. The correct implementation is to replace `false` with `force`, ensuring that the function respects the dynamic value provided by the incoming HTTP request.

The solution introduces changes not required by the instruction. It modifies the expected id value in the "computes id" test case, which was not specified in the instruction. The solution should have limited its changes only to the specified test cases to avoid unnecessary modifications.

The solution is easily fixable by reverting the unnecessary modification to the "computes id" test case.

The user's instruction is clear and feasible. It asks for a truthiness check before setting the response status code in the `start` method of the `PostmanMockServer` class. There is no lack of context or other issues that would prevent the instruction from being followed.

The solution is incorrect because it lacks error checking for file existence, which is inconsistent with other methods in the codebase. For example, the `AtomicRead` function checks if the file exists and returns `fs.ErrNotExist` if it doesn't. The `Delete` function should follow this pattern for consistency and proper error handling. This omission makes the behavior unpredictable and inconsistent with the rest of the implementation.

The fix is simple: add a file existence check and return `fs.ErrNotExist` if the file is missing, following the approach in `AtomicRead`. This can be done with a single line of code:

"Please analyze the following statement objectively, considering multiple perspectives and potential interpretations. Do not favor any particular viewpoint. Identify any strengths, weaknesses, or ambiguities in the argument. Here is the statement:
### [statement]
The instruction to "support a custom helper resolver function in the loader query" is somewhat ambiguous. It is not entirely clear how the custom helper resolver function should be integrated or what specific behavior is expected. The instruction could be interpreted in multiple ways, such as adding a new option to the loader query to specify a custom resolver function or modifying the existing helper resolution logic to accommodate custom resolvers.

 Based on the existing pattern in the file, it would be common sense to follow the same structure for adding Vietnamese locale support. The abbreviation for Vietnamese is typically vi, and it's reasonable to infer that it should be imported from a file named ./locales/vi. This pattern is consistent with how other locales are handled in the file.

### 
In your response:

1. Evaluate the logical structure and assumptions of the argument.
2. Consider potential counterarguments or alternative interpretations.
3. Highlight any areas of ambiguity or where more information might be needed.
4. If applicable, suggest how the statement could be clarified or improved.

Please provide a balanced analysis without leaning towards agreeing or disagreeing with the statement."

The plan includes unnecessary steps such as "Update any calls to the `ProcessMessage` method to match the new return type," which goes beyond the instruction. Additionally, the step "Verify that the code compiles and runs without errors" implies an external action, which is not appropriate. The instruction only asks for changing the return type, so the plan should focus solely on reviewing the `ProcessMessage` method and updating the return type from `messageprocessor.MessageProcessError` to `messageprocessor.MessageProcessorError`.

The instruction lacks context on how the sound service is managed—whether through `UserDataSource` or a separate service—making it unclear how to implement `onResume()` and `onStop()` methods without assumptions. More details on the sound service setup are needed for accurate implementation.

whats asked to update schema in the user instruction is already implemented in the source code


The user instruction does not mention where to add test case for analyzing a reader with two new Lucene text analyzers

There was an incorrect comment in instruction. 
Original Comment: 
Correct Comment: 

There was an incorrect comment in instruction. 

Original Comment: "There are no methods for validating Ethereum data types (blocks, transactions, etc.), which are critical components mentioned in the instructions. Without a concrete starting point, it’s impossible to verify the methods.

The service is expected to handle necessary parameters, but no parameters or hints about what should be included are provided in the instructions. This creates ambiguity.

The instructions require the use of Ethereum RPC methods for validation, but since the provided code is unavailable, this critical part of the implementation is entirely absent."


Correct Comment: "The instruction lacks context as it does not specify the necessary parameters for the validation methods or provide concrete examples of the methods required for validating different Ethereum data types, such as blocks and transactions. Additionally, the absence of any existing code framework limits the guidance available for implementation. While the task is generally actionable, these gaps create ambiguity and hinder a developer's ability to execute the instruction effectively."




The solution is correct in terms of functionality, as it ensures the `output()` method consistently returns an array. However, it introduces unnecessary complexity by handling the null check in the constructor, which could be simplified. This creates a code smell, as the task only required modifying the `output()` method. A cleaner approach would be to handle the null check directly within the `output()` method, making the code more efficient and easier to maintain.
    
    
    ### 
The solution makes changes to functions (`UpdateEntryContent` and `createEntry`) that were not specified in the instructions. The instructions only asked to limit the text length in the `updateEntry` function. 

This plan is correct and meets the user's requirements. 
The plan provided is complete, relevant, and includes all necessary steps to fulfill the instruction.

The solution is incorrect because it changes the method call from `Sentances` to `Sentences` in the `Paragraph` method without renaming the `Sentances` method itself. This inconsistency causes a compilation error because `Sentences` is not defined. The solution should include renaming both the method definition and all references to it to avoid breaking the code.

I updated the comment for `plan`, changed the `solution` label to `no`, and marked `easily fixable` as `yes`.

We can't mark code smells for issues that are already present in the original code based on the criteria.

 the solution did not include the declaration of new static final HarvesterConfig fields for the twisting vines and weeping vines, which is necessary for consistency with the other crhops in the configuration class.

The plan includes unnecessary steps for implementing the functions, which is not appropriate for a header file. The instruction only asked to "Add functions to the string library," which, for a `.h` file, means adding function declarations (prototypes) only.

The instruction asks to add a parameter of type Major to the `Lesson` class constructor. However, the `Major` type is not defined in the provided code snippet, nor is there any indication that it's a widely-used library type.

The solution is easy to fix, as unnecessary changes can be undone in under a minute.

The solution is not easily fixable because it requires multiple lines of modification to meet the user's instructions.

The solution is easily fixable because it requires a single line of modification to meet the user's instructions.

I changed the label for `plan` to `bad`.
I changed the label for `easily fixable` to `no`.
I changed the instruction label to ambiguous.
I changed the instruction label to lack of context.
I changed the instruction label to non-solvable.


I changed the labels as follows: `plan` is now labeled as `bad`, and both `solution` and `easily fixable` are now labeled as `no`.

I changed the labels as follows: instruction is now labeled as good, plan as bad, solution as not correct, and easily fixable as yes.

I changed the labels as follows: instruction is now labeled as good, plan as bad, solution as correct, and there is no code smell.

I changed the labels as follows: instruction is now labeled as good, solution as correct, and it has no code smell.

I changed the labels as follows: instruction is now labeled as good, plan as good, solution as correct, it has no code smell, and it implements the plan.



I changed the labels for `solution` and `easily fixable` to `no`.
I changed the labels for `solution` to `no` and `easily fixable` to `yes`.

The plan contains a non-mental step (verifying compilation and runtime behavior), which goes beyond the acceptable mental actions outlined in the criteria.

The plan includes unnecessary steps that are not required to make the code change. Specifically, the plan mentions locating the file, opening it in a text editor, and saving and closing the file, which are steps outside the code change itself.

The solution updates the `WriteIntoDeltaBuilder` class to use `table.deltaLog` instead of `log` when calling `WriteIntoDelta` as the user requested, but there is an encoding issue between lines 314 and 323, where `<0x06>` appears with the line number at the start of each line. These problems must be fixed for the code to run correctly.

The solution failed to delete `MetaRepoImpl` class correctly. It only removes part of the class, didn't remove the other commented methods and the closing bracket `}`, which were also part of the class. Additionally, there are formatting issues between lines 8 and 13, where `<0x06>` appears along with the line number at the start of each line, likely due to an encoding error. These issues need to be fixed for the code to be executable.



The solution has formatting issues between lines 21 and 27, where `<0x06>` appears along with the line number at the start of each line. This seems to be an encoding error or unintended artifact that must be corrected for the code to run properly.

The solution updates the comment but has formatting issues between lines 9 and 16. The lines start with `<0x06>` and the line number, likely due to an encoding error. This needs to be fixed for the code to run correctly.

The solution is easily fixable with three lines of modification to remove unnecessary changes (unexpected value `0x06` with line numbers). It doesn’t meet the one-line modification criteria but can be corrected in under a minute.

The solution is incorrect because it introduces unnecessary hexadecimal codes (<0x06>) in lines 201 to 210, which could cause readability and compilation issues. It also does not follow the plan properly.

The solution requires multiple lines of modifications to undo unnecessary changes, so it doesn't meet the `easily fixable` criterion.
 
The instruction lacks context because it asks to update `PostsRepositoryImpl` to use `PostsMapper` in the `fetchPosts()` method. However, the provided source code does not mention or define `PostsMapper`. There is no information about what `PostsMapper` is, how it should be used, or what its methods are.
 
The plan contains unnecessary steps that aren't directly related to modifying the code, such as "Open the skyproto.h file in a text editor" and "Save the changes to the `skyproto.h` file." It should instead concentrate on the essential steps needed to implement the change.

The plan is bad because it includes a non-mental step, "Save and compile the changes to ensure there are no syntax errors."

Although the final step of the plan is not essential, it's a "mental" action that doesn't make the plan incorrect. According to the criteria, mental actions like "ensure consistent use of variable X" or "verify" are allowed and do not invalidate the plan.


The solution incorrectly duplicates the import statement for `issuesHandler` and includes the unexpected string "<0x06>" along with line numbers 3 to 8, which will cause a compilation error.

The solution is incorrect because it does not fully match the plan. The plan specified a function with two parameters (`fieldName` and `api`), but the solution only implemented one. Additionally, the presence of unnecessary hexadecimal codes (<0x06>) makes the code non-executable.

The solution is incorrect as it doesn't fully align with the plan. The plan required adding a new attribute `testEnumList` of type `List<MyEnum>` to the `FetchValueRequest` class. Additionally, the presence of unnecessary hexadecimal codes (`<0x06>`) and the lines from 35 to 46 make the code non-executable.



The solution is incorrect because it fails to remove a function call to the `Determinant` function. Additionally, unnecessary hexadecimal codes (`<0x06>`) with line numbers appear in lines 643 to 648. These issues may cause compilation errors and were not part of the task.

The solution isn't easily fixable because it involves multiple modifications to remove the `Determinant` function call and to reverse unnecessary changes (such as an unexpected hexadecimal value `0x06` with line numbers).

The solution can be easily fixed by undoing the unnecessary replacement of the `finish` event listener in `FileStore.combineObjectParts`.

The solution incorrectly adds the unexpected hexadecimal value `0x06` along with line numbers 179 to 191, which will cause a compilation error.

The solution is not easily fixable because it requires multiple lines of modification to undo unnecessary changes.

The solution is not easily fixable because it requires multiple lines of modification to undo unnecessary changes and to add a new attribute `testEnumList` as specified in the plan.

The solution requires multiple lines of modification to undo unnecessary changes and to remove the blank line, so it doesn't meet the `easily fixable` criterion. 

The solution is incorrect because it doesn't follow the user's instructions. It adds the unexpected hexadecimal value `0x06` along with line numbers 16 to 44, which will lead to a compilation error.

### 

There was an incorrect comment in instruction. 

Original Comment: "The current implementation lacks specific tests for mock[T] with specialized methods. Tests should be added to validate how mock[T] interacts with these methods."

This justification accurately points out that the instruction is ambiguous about the specifics of what the test case should accomplish. However, it contains an incorrect assertion regarding the Spark ML documentation. While it is true that the instruction does not provide explicit details about the contents or goals of the test case, it is misleading to claim that "no documentation named Spark ML is present." In fact, Spark ML (Machine Learning) is a well-known component of Apache Spark, and its documentation is readily accessible.


Correct Comment: "The instruction is ambiguous because the term 'specialized methods' is not defined clearly. The current code already tests the behavior of `mock[T]` in various scenarios, such as `by-name` arguments and `Function0` arguments. However, it’s unclear if the instruction is asking for new test cases or simply a validation of the existing ones. Clarification is needed on what specific behaviors or methods should be tested with `mock[T]`."



The previous justification is invalid because it inaccurately claims that the instruction lacks context. The instruction is clear and provides sufficient context for adding a test for the Hungarian (`hu`) locale. 

The existing test file contains examples of how to structure locale-specific tests, making it straightforward to follow the same pattern to add the new test. The instruction does not lack context; it specifies exactly what to add (a test for the `hu` locale) and the existing tests serve as clear templates for implementation.
