│    Your job is to finish/polish the patch following the instructions    │
│    below.                                                               │

│                                                                         │
│    ### **LLM Prompt: Fixing Unsafe Buffer Usage in Chromium**           │
│                                                                         │
│    **Role:** You are an expert C++ developer specializing in memory     │
│    safety for the Chromium project. Your primary goal is to eliminate   │
│    unsafe buffer operations by migrating legacy C-style code to modern, │
│     safer C++ constructs, with a strong emphasis on `base::span` and    │
│    other standard library containers. You must adhere to Chromium's     │
│    coding standards and the specific guidelines for this task.          │
│                                                                         │
│    **Task:** Your task is to fix unsafe buffer usage in a given C++     │
│    file. You should compile the target with provided command line after │
│     removing the `#pragma allow_unsafe_buffers` and `UNSAFE_TODO`       │
│    directive. You will use these errors to identify and fix the unsafe  │
│    code, applying the principles and patterns outlined below. **Your    │
│    changes must be minimal and targeted, directly addressing only the   │
│    unsafe buffer errors.** While the primary focus is on the given      │
│    file, you are expected to modify other files (e.g., header files or  │
│    call sites) if necessary to ensure the code compiles and tests pass. │
│                                                                         │
│    ### **Guiding Philosophy**                                           │
│    *   **Safety Through the Type System:** The fundamental goal is to   │
│    encode buffer size information into the C++ type system. A `char*`   │
│    has no size information, making it unsafe. A `base::span<char>` has  │
│    a size, making it safe. Every change you make should serve this      │
│    principle.                                                           │
│    *   **Minimalism is Essential:** Your task is not to refactor or     │
│    improve the code in general. You are a specialist surgeon fixing one │
│     specific problem: unsafe buffer usage. Make the smallest possible   │
│    change that fixes the compiler warning and passes tests.             │
│    *   **Trust, But Verify with Compilation:** Your primary feedback    │
│    loop is the compiler. After removing the `allow_unsafe_buffers`      │
│    pragma, the `-Wunsafe-buffer-usage` errors are your map. Use them to │
│     identify every location that needs a fix.                           │
│                                                                         │
│                                                                         │
│    You must refer to these documents to ensure your solutions are       │
│    idiomatic and correct within the Chromium ecosystem.                 │
│                                                                         │
│    # Workflow Tips                                                      │
│                                                                         │
│    ## General Workflow:                                                 │
│                                                                         │
│      * **User Guidance:** Proactively communicate your plan and the     │
│    reason for each                                                      │
│        step.                                                            │
│      * **File Creation Pre-check:** Before creating any new file, you   │
│    MUST first                                                           │
│        perform a thorough search for existing files that can be         │
│    modified or                                                          │
│        extended. This is especially critical for tests; never create a  │
│    new test                                                             │
│        file if one already exists for the component in question. Always │
│     add new                                                             │
│        tests to the existing test file.                                 │
│      * **Read Before Write/Edit:** **ALWAYS** read the entire file      │
│    content                                                              │
│        immediately before writing or editing.                           │
│                                                                         │
│    ## MANDATORY DEBUGGING PROTOCOL (WHEN STUCK)                         │
│                                                                         │
│      * **Trigger:** You **MUST** activate this protocol if you          │
│    encounter a                                                          │
│        **Repeated Tool or Command Failure**.                            │
│                                                                         │
│          * **Definition of Repeated Failure:** A tool or command (e.g., │
│            `autoninja`, `autotest.py`, `git cl format`, `replace`)      │
│    fails. You apply                                                     │
│            a fix or change your approach. You run the *exact same tool  │
│    or command*                                                          │
│            again, and it fails for a **second time**.                   │
│          * **Sensitivity:** This protocol is intentionally highly       │
│    sensitive. The                                                       │
│            error message for the second failure does **NOT** need to be │
│     the same as                                                         │
│            the first. Any subsequent failure of the same tool or        │
│    command after a                                                      │
│            fix attempt is a trigger. This is to prevent "whack-a-mole"  │
│    scenarios                                                            │
│            where fixing one error simply reveals another, indicating a  │
│    deeper                                                               │
│            underlying problem.                                          │
│                                                                         │
│        *Check your history to confirm the repeated failure of the tool  │
│    or command.*                                                         │
│                                                                         │
│      * **Action:** If the trigger condition is met:                     │
│                                                                         │
│        1.  **STOP:** **DO NOT** immediately retry the *same* fix or     │
│    re-run the                                                           │
│            *same* tool or command again.                                │
│        2.  **INFORM USER:** Immediately inform the user that you are    │
│    invoking the                                                         │
│            debugging protocol because a tool or command has failed      │
│    twice in a row.                                                      │
│        3.  **REASON:** **Explicitly state** which tool or command       │
│    failed repeatedly                                                    │
│            (e.g., "`autotest` failed, I applied a fix, and it failed    │
│    again. I am                                                          │
│            now invoking the debugging protocol to analyze the root      │
│    cause.").                                                            │
│            Mentioning the specific error messages is good, but the      │
│    repeated failure                                                     │
│            is the primary trigger.                                      │
│        4.  **DEBUG:** Look closely into your own context, memory, and   │
│    traces. Give                                                         │
│            a deep analysis of why you are repeating mistakes and stuck  │
│    in a failure                                                         │
│            loop. The analysis should focus on the *root cause* of the   │
│    repeated                                                             │
│            failures, not just the most recent error message. Utilize    │
│    any tools that                                                       │
│            help with the debugging investigation.                       │
│        5.  **PROCEED:** Use the suggestions returned by the DEBUG step  │
│    to inform                                                            │
│            your next attempt at a fix. Explain the new, more            │
│    comprehensive plan to                                                │
│            the user. If the DEBUG step provides tool calls, execute     │
│    them.                                                                │
│            Otherwise, formulate a new plan based on its suggestions.    │
│                                                                         │
│    Do not use the `read_many_files` tool. Read files one at a time with │
│    `read_file`.                                                         │
│                                                                         │
│    Any time you want to use `grep -r`, use `rg` instead.                │
│                                                                         │
│    Any time you want to use `find`, use `fdfind` instead.               │
│                                                                         │
│    ## Standard Edit/Fix Workflow:                                       │
│                                                                         │
│    **IMPORTANT:** This workflow takes precedence over all other coding  │
│    instructions. Read and follow everything strictly without skipping   │
│    steps                                                                │
│    whenever code editing is involved. Any skipping requires a proactive │
│     message to                                                          │
│    the user about the reason to skip.                                   │
│                                                                         │
│    1.  **Comprehensive Code and Task Understanding (MANDATORY FIRST     │
│    STEP):** Before                                                      │
│        writing or modifying any code, you MUST perform the following    │
│    analysis to                                                          │
│        ensure comprehensive understanding of the relevant code and the  │
│    task. This                                                           │
│        is a non-negotiable prerequisite for all coding tasks.           │
│          * **a. Identify the Core Files:** Locate the files that are    │
│    most relevant                                                        │
│            to the user's request. All analysis starts from these files. │
│          * **b. Conduct a Full Audit:**                                 │
│            i. Read the full source of **EVERY** core file.              │
│            ii. For each core file, summarize the control flow and       │
│    ownership                                                            │
│            semantics. State the intended purpose of the core file.      │
│          * **c. State Your Understanding:** After completing the audit, │
│     you should                                                          │

│          * When making code edits, focus **ONLY** on code edits that    │
│    directly solve                                                       │

│          * First, search for existing tests related to the modified     │
│    code and update                                                      │
│            them as needed to reflect the changes.                       │
│          * If no relevant tests exist, write new unit tests or          │
│    integration tests if                                                 │
│            it's reasonable and beneficial for the change made.          │
│          * If tests are deemed not applicable for a specific change     │
│    (e.g., a                                                             │
│            trivial comment update), explicitly state this and the       │
│    reason why before                                                    │

│    4.  **Build:** **ALWAYS** build relevant targets after making edits. │
│    5.  **Fix compile errors:** **ALWAYS** follow these steps to fix     │
│    compile errors.                                                      │
│          * **ALWAYS** take the time to fully understand the problem     │
│    before making                                                        │
│            any fixes.                                                   │
│          * **ALWAYS** read at least one new file for each compile       │
│    error.                                                               │
│          * **ALWAYS** find, read, and understand **ALL** files related  │
│    to each                                                              │
│            compile error. For example, if an error is related to a      │
│    missing member                                                       │
│            of a class, find the file that defines the interface for the │
│     class, read                                                         │
│            the whole file, and then create a high-level summary of the  │
│    file that                                                            │
│            outlines all core concepts. Come up with a plan to fix the   │
│    error.                                                               │
│          * **ALWAYS** check the conversation history to see if this     │
│    same                                                                 │
│            error occurred earlier, and analyze previous solutions to    │
│    see why they                                                         │
│            didn't work.                                                 │
│          * **NEVER** make speculative fixes. You should be confident    │
│    before                                                               │
│            applying any fix that it will work. If you are not           │
│    confident, read more                                                 │
│            files.                                                       │
│    6.  **Test:** **ALWAYS** run relevant tests after a successful       │
│    build. If you                                                        │
│        cannot find any relevant test files, you may prompt the user to  │
│    ask how this                                                         │
│        change should be tested.                                         │
│    7.  **Fix test errors**:                                             │
│        * **ALWAYS** take the time to fully understand the problem       │
│    before making                                                        │

│    8.  **Iterate:** Repeat building and testing using the above steps   │
│    until all are                                                        │
│        successful.                                                      │
│                                                                         │

│    ### **Core Principles for Safe Buffer Handling**                     │
│                                                                         │
│    Before looking at specific patterns, adhere to these fundamental     │
│    principles.                                                          │
│                                                                         │
│    *   **Principle 0: Clearly Distinguish Ownership**                   │
│        Before you change any code, your first step is to determine if   │
│    the variable in question represents owning or non-owning memory.     │
│    This single decision dictates the correct C++ type to use.           │
│                                                                         │
│        *   **Owning Buffers:** Use an owning container when the code is │
│     responsible for the memory's lifetime (allocating and freeing it).  │
│            *   `std::vector<T>`: This is the default and preferred      │
│    choice for a dynamically-sized, owning buffer.                       │
│            *   `std::string`: The standard choice for owning a buffer   │
│    of characters.                                                       │
│            *   `std::array<T, N>`: Use this for a fixed-size buffer     │
│    whose lifetime is tied to its scope (typically on the stack). It's a │
│     direct, safer replacement for C-style arrays like `int              │
│    my_array[10];`.                                                      │
│            *   `base::HeapArray<T>`: A Chromium-specific alternative    │
│    for heap-allocated arrays, sometimes useful for interfacing with     │
│    legacy code.                                                         │
│                                                                         │
│        *   **Non-Owning Buffers (Views/Spans):** Use a non-owning view  │
│    when the code needs to safely refer to and operate on memory that is │
│     owned by another object (like a `std::vector` or `std::array`).     │
│            *   `base::span<T>`: This is the default and preferred       │
│    choice for a non-owning, mutable, or immutable view of a contiguous  │
│    sequence of objects. It's the primary tool for replacing `(T* ptr,   │
│    size_t size)` parameters.                                            │
│            *   `std::string_view`: Use this for a non-owning, read-only │
│     view of a sequence of characters. It provides a rich set of         │
│    string-manipulation methods (`.starts_with()`, `.find()`, etc.) that │
│     `base::span<const char>` lacks.                                     │
│                                                                         │
│    *   **Principle 1: Avoid Unsafe APIs, Even If They Look Modern.**    │
│    The goal is to eliminate the *root cause* of unsafety, not just      │
│    silence the compiler. Certain modern-looking APIs are still unsafe.  │
│                                                                         │
│        *   **DO NOT USE:** The `base::span(pointer, size)` constructor. │
│     It is marked `UNSAFE_BUFFER_USAGE` for a reason—it does not verify  │
│    that `size` is a valid length for `pointer`. Using it is no safer    │
│    than the original code.                                              │
│        *   **DO NOT USE:** `std::next()` or `std::advance()` to silence │
│     buffer warnings. These functions perform unchecked pointer          │
│    arithmetic and are just as unsafe as `ptr + offset`.                 │
│            ```cpp                                                       │
│            // Old and Unsafe (silences warning, but still dangerous):   │
│            auto it = std::find(std::next(vec.begin(), offset),          │
│    vec.end(), 20);                                                      │
│            // New and Safe:                                             │
│            auto it = std::ranges::find(base::span(vec).subspan(offset), │
│     20);                                                                │
│            ```                                                          │
│        *   **DO NOT USE:** `base::StringView`. This is a legacy,        │
│    deprecated type. The correct and modern type for a non-owning string │
│     view is `std::string_view`. Be mindful to use the `std` namespace   │
│    for string views.                                                    │
│        *   **DO NOT USE: `UNSAFE_BUFFERS` without a safety              │
│    justification.** Individual expressions can be opted out with        │
│    `UNSAFE_BUFFERS()`, but these are for rare cases like interfacing    │
│    with C-style external APIs. They **must always** be accompanied by a │
│     `// SAFETY:` comment explaining in detail why the code has been     │
│    evaluated to be safe for all possible inputs. Code without this      │
│    justification should be rejected.                                    │
│                                                                         │
│    *   **Principle 3: Prefer Safe, Size-Aware Constructors and          │
│    Factories.** Always create spans from sources that already know      │
│    their own size. This is the key to memory safety.                    │
│                                                                         │
│        *   **DO USE:** `base::span(container)` where `container` is an  │
│    `std::vector`, `std::array`, `std::string`, `base::HeapArray`, etc.  │
│        *   **DO USE:** `base::span(other_span).subspan(...)` to create  │
│    safe views into existing spans.                                      │
│        *   **DO USE:** `base::as_byte_span(container)` and              │
│    `base::as_writable_byte_span(container)` for safe type-punning to a  │
│    byte view.                                                           │
│        *   **DO USE:** `base::span_from_ref(object)` to create a span   │
│    of size 1 pointing to a single object.                               │
│        *   **DO USE:** `base::byte_span_from_ref(object)` for a byte    │
│    view of a single object.                                             │
│                                                                         │

│                                                                         │
│    Here is a comprehensive set of patterns for fixing common unsafe     │

│    The most common task is replacing raw pointers and C-style arrays    │
│    with safer, bounds-checked alternatives.                             │

│    *   **Pattern:** Replace function parameters `(T* ptr, size_t size)` │

│        *   **Reasoning:** `std::vector` and `base::HeapArray` are       │

│    *   **Pattern:** When passing an array to a function, use            │

│            std::array<int, 10> my_array;                                │
│            // Old: ProcessData(my_array.data(), my_array.size());       │
│            // New                                                       │
│            ProcessData(base::span(my_array));                           │
│            ```                                                          │
│    *   **Pattern:** For class member fields that are non-owning views,  │
│    you must use `base::raw_span<T>` over `base::span<T>`.               │
│        *   **Reasoning:** This is a critical memory safety requirement. │
│     `base::raw_span` is implemented with MiraclePtr, which protects     │
│    against Use-After-Free (UAF) bugs. If the underlying object is       │
│    freed, any attempt to use the `raw_span` will result in a controlled │
│     crash instead of allowing dangerous memory corruption or type       │
│    confusion attacks. A regular `base::span` offers no UAF protection.  │
│        ```cpp                                                           │
│        class MyClass {                                                  │

│          // Old: base::span<int> data_;                                 │
│          // New:                                                        │
│          base::raw_span<int> data_;                                     │
│        };                                                               │
│        ```                                                              │
│                                                                         │

│                                                                         │
│    *   **Pattern:** Replace `memcpy` and `memmove` with                 │
│    `base::span::copy_from()`.                                           │
│        *   **Reasoning:** Do not use `std::ranges::copy`. It is unsafe  │
│    because it does not verify that the source and destination spans     │
│    have the same size, which can lead to buffer overflows.              │
│    `base::span::copy_from()` is the only safe alternative, as it        │
│    includes a `CHECK` to ensure the sizes match exactly.                │
│        *   **Example:**                                                 │
│            ```cpp                                                       │

│            memcpy(dest_ptr, src_ptr, N);                                │

│            // New (Safe and Idiomatic)                                  │
│            // This CHECKs that both subspans are of size N.             │
│            dest_span.first(N).copy_from(src_span.first(N));             │
│            ```                                                          │

│    *   **Pattern:** Replace `memset` with `std::ranges::fill()`.        │
│                                                                         │

│    *   **Pattern:** Refactor sequential buffer filling with a           │

│        *   **Reasoning:** Instead of managing a write-pointer and an    │
│    end-pointer manually, a single `base::span` can represent the        │
│    remaining, writable portion of the buffer. This is safer and more    │
│    expressive.                                                          │

│        *   **Key Idea:** The core of this pattern is to create a helper │
│     function (like `WriteStringAndAdvance`) that takes the main buffer  │
│    span by reference (`&`). The helper writes its data and then         │
│    reassigns the span to a smaller subspan, effectively advancing the   │
│    "write position" for the next operation in the calling function.     │
│                                                                         │
│    #### **4. String and Character Manipulation**                        │
│                                                                         │
│    *   **Pattern:** Replace C-style string literals (`const char        │
│    kFoo[]`) with `constexpr std::string_view kFoo` or `constexpr        │
│    std::array`.                                                         │
│    *   **Pattern:** For C APIs that require a NUL-terminated string,    │
│    use `base::cstring_view`.                                            │
│    *   **Pattern:** Replace C-style string functions (`strcmp`,         │
│    `strstr`, etc.) with `std::string_view` methods (`operator==`,       │
│    `.find()`, etc.).                                                    │
│    *   **Pattern:** Replace pointer-based iteration over a buffer with  │
│    a range-based for loop over a `base::span`.                          │
│    *   **Pattern:** Choose the correct string view type based on        │
│    null-termination requirements.                                       │
│        *   **Reasoning:** You must differentiate between internal C++   │
│    logic and calls to C-style APIs. A `std::string_view` is not         │
│    guaranteed to be null-terminated, while `base::cstring_view`         │
│    provides this guarantee. Using the wrong type can lead to buffer     │
│    over-reads.                                                          │
│        *   **Decision Flow:**                                           │
│            *   If the string is only used with modern C++ methods (like │
│     `.find()` or range `for` loops) that use an explicit size, use      │
│    `std::string_view`.                                                  │
│            *   If the string needs to be passed to an API that requires │
│     a null-terminated `const char*` (like `printf`, `sscanf`, or legacy │
│     functions), you must use `base::cstring_view`.                      │
│        *   **Example:**                                                 │

│    *   **Pattern:** To get a heap-allocated buffer with a specific      │
│    memory alignment, use `base::AlignedUninit<T>` from                  │
│    `base/memory/aligned_memory.h`.                                      │
│        ```cpp                                                           │
│        #include "base/memory/aligned_memory.h"                          │
│        // Get an uninitialized array of 16 floats, aligned to 32 bytes. │
│        base::AlignedHeapArray<float> array =                            │
│    base::AlignedUninit<float>(16, 32);                                  │
│        ```                                                              │
│                                                                         │
│    #### **6. Common Chromium-Specific Patterns**                        │
│                                                                         │
│    *   **`net::IOBuffer`:** This class and its subclasses               │
│    (`IOBufferWithSize`, `VectorIOBuffer`) now have span-like methods.   │
│    Use them.                                                            │
│                                                                         │
│        *   **Example:**                                                 │
│            ```cpp                                                       │
│            // Old                                                       │

│                reinterpret_cast<const uint8_t*>(io_buffer->data()),     │
│    data_len);                                                           │
│                                                                         │
│            // New                                                       │
│            auto data_view = io_buffer->first(data_len);                 │
│            ```                                                          │

│    *   **`net::VectorIOBuffer`:** To create a buffer with known         │
│    content, prefer constructing a `net::VectorIOBuffer` directly from a │
│     `std::vector` or `base::span` instead of allocating a raw buffer    │
│    and using `memcpy`.                                                  │
│                                                                         │
│        *   **Example:**                                                 │
│            ```cpp                                                       │
│            // Old                                                       │

│    base::MakeRefCounted<net::IOBufferWithSize>(data.size());            │
│            memcpy(buffer->data(), data.data(), data.size());            │
│                                                                         │
│            // New                                                       │

│                                                                         │
│    #### **7. Interfacing with C-style/Third-Party APIs**                │
│                                                                         │
│    *   **Pattern:** When a C API returns pointers to different memory   │
│    planes (e.g., video frames), create `base::span`s from those         │
│    pointers and their known sizes at the API boundary. Use              │
│    `UNSAFE_BUFFERS()` for this initial creation, then pass the safe     │
│    spans throughout the rest of your C++ code.                          │
│        *   **Example:**                                                 │
│            ```cpp                                                       │
│            // Old                                                       │
│            uint8_t* y_ptr = vpx_image->planes[0];                       │
│            uint8_t* u_ptr = vpx_image->planes[1];                       │
│            VideoFrame::WrapExternalYuvData(..., y_ptr, u_ptr, ...);     │
│                                                                         │
│            // New                                                       │
│            // SAFETY: libvpx guarantees these pointers and sizes are    │
│    valid.                                                               │
│            auto y_plane =                                               │
│    UNSAFE_BUFFERS(base::span(vpx_image->planes[0], y_size));            │
│            auto u_plane =                                               │
│    UNSAFE_BUFFERS(base::span(vpx_image->planes[1], u_size));            │
│            VideoFrame::WrapExternalYuvData(..., y_plane, u_plane, ...); │
│            ```                                                          │
│                                                                         │
│    #### **8. The Containment Strategy: When a Full Fix is Too Complex** │
│                                                                         │
│    Sometimes, a complete refactor is not immediately feasible. In these │
│     cases, contain the unsafe operations.                               │
│                                                                         │
│    *   **Strategy:** Instead of a file-level `#pragma`, wrap the        │
│    *minimal* number of unsafe operations in the `UNSAFE_TODO()` macro.  │
│    This macro acts like `UNSAFE_BUFFERS()` but signals that the code is │
│     a candidate for a future fix.                                       │
│    *   **Function-level Annotation:** If a function contains            │
│    `UNSAFE_TODO()`, you must also mark the function's signature with    │
│    the `UNSAFE_BUFFER_USAGE` attribute. This propagates the unsafety    │
│    requirement to its callers, ensuring they are also marked or within  │
│    an unsafe block.                                                     │
│        *   **Example:**                                                 │
│            ```cpp                                                       │
│            // Old:                                                      │
│            // #pragma allow_unsafe_buffers                              │
│            // void DoSomething(const char* p) {                         │
│            //   p++;                                                    │
│            // }                                                         │
│                                                                         │

│            UNSAFE_BUFFER_USAGE void DoSomething(const char* p) {        │
│              UNSAFE_TODO(p++);                                          │
│            }                                                            │
│            ```                                                          │
│                                                                         │
│    #### **9. Handling Redundant Parameters**                            │
│                                                                         │
│    *   **Identify redundant parameters:** In functions that now take a  │
│    base::span, find any size parameters that are now unneeded. A        │
│    parameter is still considered redundant even if it's already used in │
│     a CHECK or DCHECK.                                                  │
│                                                                         │
│    *   **Rename the parameter:** For any redundant parameter, rename it │
│     and all its references within the function by adding the prefix     │
│    spanification_suspected_redundant_.                                  │
│                                                                         │
│    *   **Add a TODO and a CHECK:** At the top of the function body, add │
│     the following two lines:                                            │
│                                                                         │
│        *   A TODO comment:                                              │
│            ```cpp                                                       │
│            // TODO(crbug.com/431824301): Remove unneeded parameter once │

│            ```                                                          │
│        *   A CHECK to verify the redundant parameter matches the span's │
│     size:                                                               │
│            ```cpp                                                       │
│            CHECK(spanification_suspected_redundant_size_variable ==     │
│    span.size(), base::NotFatalUntil::M143);                             │
│            ```                                                          │
│                                                                         │
│    *   **Customize the CHECK:** In the CHECK you just added, you must:  │
│                                                                         │
│        *   Replace spanification_suspected_redundant_size_variable with │
│     the new name of the parameter you renamed in step 2.                │
│                                                                         │
│        *   Replace span.size() with a call to the actual base::span     │
│    parameter's .size() method.                                          │
│                                                                         │
│    *   **Important constraints:**                                       │
│                                                                         │
│        *   Do not remove the parameter or update any call sites.        │
│                                                                         │
│        *   Do not change the function's logic to use span.size();       │
│    continue to use the newly-renamed parameter variable.                │
│                                                                         │
│        *   Do ensure the size parameter and the base::span's size are   │
│    in the same unit before making changes.                              │
│                                                                         │
│        *   Do not remove the parameter or the CHECK even if you         │
│    confirmed that the unit tests pass.                                  │
│                                                                         │
│    #### **10. Updating Function Definitions and Call Sites**            │
│                                                                         │
│    *   **Updating the Function Definition**                             │
│        *   **Identify the target function:** Look for functions that    │
│    have a parameter with the name pattern                               │
│    spanification_suspected_redundant_....                               │
│        *   **Remove the parameter:** In the function's definition and   │
│    any corresponding declarations (e.g., in a header file), completely  │
│    remove the redundant size parameter from the parameter list.         │
│        *   **Replace internal usages:** Inside the function's body,     │
│    replace every use of the removed parameter with a call to the        │
│    base::span's .size() method (e.g., my_span.size()).                  │
│                                                                         │
│    *   **Updating the Call Sites**                                      │
│        *   **Find all call sites:** Use a command like git grep with    │
│    the function name to find every location where the function is       │
│    called throughout the codebase.                                      │
│        *   **Remove the argument at each call site:** For each call     │
│    site you find, you must remove the argument that corresponds to the  │
│    size parameter you deleted from the function's definition.           │
│        *   **Important:** Be very careful to only remove the specific,  │
│    redundant argument. Do not change or remove any other arguments in   │
│    the function call.                                                   │
│                                                                         │
│    *   **Key Constraints**                                              │
│        *   You should only remove the parameter previously marked as    │
│    redundant and its corresponding arguments at call sites.             │
│        *   Do not remove or rename any other parameters.                │
│        *   Do not rewrite the function's logic beyond replacing the     │
│    deleted variable with span.size().                                   │
│        *   Ensure that when you update a call site, you only remove the │
│     single, correct argument.                                           │
│                                                                         │
│    #### **11. Handling Autogenerated Files**                            │
│                                                                         │
│    *   **Pattern:** Another common pattern is for a change to require   │
│    modification to an autogenerated file. Treat autogenerated files as  │
│    unmodifiable for now.                                                │
│    ---                                                                  │
│    #### **12. Wrapping Unsafe APIs with Macros**                        │
│                                                                         │
│    In some cases, you will encounter functions from third-party         │
│    libraries or other unmodifiable parts of the codebase that return a  │
│    raw pointer to a buffer. Directly wrapping these with                │
│    `UNSAFE_BUFFERS(base::span(pointer, size))` is one option, but a     │
│    more robust and reusable solution is to create a dedicated wrapper   │
│    macro in `base/containers/auto_spanification_helper.h`.              │
│                                                                         │
│    *   **Strategy:** When an unmodifiable function call returns a raw   │
│    pointer instead of a safe container like `base::span`, follow this   │
│    procedure:                                                           │
│        1.  **Check for an existing macro:** First, examine              │
│    `base/containers/auto_spanification_helper.h` to see if a macro for  │
│    this specific API call already exists.                               │
│        2.  **Create a new macro if needed:** If no macro exists, you    │
│    must add one.                                                        │
│            *   The macro should be added to                             │
│    `base/containers/auto_spanification_helper.h`.                       │
│            *   The macro should take the same arguments as the original │
│     API call.                                                           │
│            *   Inside the macro, call the original API, get the pointer │
│     and size, and return a `base::span`. Use `UNSAFE_TODO` to wrap the  │
│    returned span.                                                       │
│            *   Follow the existing macro patterns in the file, using a  │
│    lambda to avoid multiple argument evaluation.                        │
│        3.  **Add a test for the new macro:** You must add a new test    │
│    case to `base/containers/auto_spanification_helper_unittest.cc`.     │
│            *   The test should mock the third-party API and verify that │
│     the macro correctly creates a `base::span` with the expected data   │
│    and size.                                                            │
│        4.  **Use the macro:** Replace the original unsafe API call in   │
│    your target file with the new or existing macro.                     │
│                                                                         │

│    Pattern: Refactor sequential buffer filling with a "consuming span". │
│     This is for cases where a buffer is allocated once, and then a      │
│    pointer is manually advanced as data is written to it sequentially.  │
│                                                                         │
│    Reasoning: Instead of managing a write-pointer and an end-pointer    │
│    manually, a single base::span can represent the remaining, writable  │
│    portion of the buffer. This is safer and more expressive.            │
│                                                                         │

│    span to a smaller subspan, effectively advancing the "write          │
│    position" for the next operation in the calling function.            │

✦ Okay, I will finish the patch to spanify
  components/feedback/redaction_tool/redaction_tool.cc and
  components/feedback/redaction_tool/redaction_tool.h.

  First, I'll examine the current patch to understand the changes made
  so far.

✦ I've reviewed the patch. The conversion to base::span has been started,
  but there are correctness issues. The RedactionTool constructor
  incorrectly initializes its first_party_extension_ids_ member with
  .data(), losing size information. Additionally, the IsUrlExempt function
   still uses a C-style loop instead of a safer range-based for loop.

  I'll now read both files to get the full context before I make any
  changes.

✦ I've reviewed the files. My plan is to correct the
  first_party_extension_ids_ initialization in the RedactionTool constructor
  in redaction_tool.cc to use the first_party_extension_ids span directly.
  I'll also update the IsUrlExempt function to use a range-based for loop.
  After removing the allow_unsafe_buffers pragma, I'll compile to check for
  further errors. I'll start with redaction_tool.cc.

✦ I just ran the get_valid_build_directories_for_current_host command to
  find a suitable build directory for compiling components_unittests. This
   helps ensure that I can build and test my changes in an environment
  that is correctly configured for the current system.Okay, I will
  proceed. I'll select a build directory from the list and then compile
  components_unittests to check for any further errors.

✦ The build failed. The error indicates that a call site in
  components/feedback/system_logs/system_logs_fetcher.cc is still using
  the old const char* const* type instead of base::span. I need to read
  that file and update the call site.

✦ I see the problem. SystemLogsFetcher is creating a RedactionTool with a
  const char* const[], but the constructor now expects a base::span. I
  need to change the SystemLogsFetcher constructor to accept a base::span
  and then update the call to std::make_unique<redaction::RedactionTool>.
  I'll start by modifying the header file.
 ╭────────────────────────────────────────────────────────╮

✦ Okay, I will modify components/feedback/system_logs/system_logs_fetcher.h
  to accept a base::span in its constructor.

✦ Now to update the constructor declaration.
✦ My apologies, I made a mistake in the file path. I will correct it and
  proceed with updating the constructor declaration in
  components/feedback/system_logs/system_logs_fetcher.h.

✦ You are absolutely correct. My apologies. It seems I got ahead of
  myself. The previous change to the constructor signature was all that
  was needed. The make_unique call is already correct.

  Now that I've updated the SystemLogsFetcher to use base::span, I need
  to find the call sites of the SystemLogsFetcher constructor and update
   them. I'll use rg to find them.

✦ I see a few places where SystemLogsFetcher is constructed with nullptr
  for the extension IDs. I'll start by reading
  chrome/browser/feedback/system_logs/about_system_logs_fetcher.cc to see
  how it's used there.

✦ In about_system_logs_fetcher.cc, SystemLogsFetcher is called with nullptr
  because scrub_data is false. I'll replace nullptr with an empty
  base::span.

✦ I've made a couple of mistakes. base::StringToUint expects an unsigned
  int*, not an unsigned long*. And I can't compare a const char* with a
  string literal directly. I'll fix these now. First, the StringToUint
  call.

✦ It seems I made a mistake and components_unittests is a build target, not
  a test suite. I should have realized that from the build command. I will
  try to find the correct test suite to run. I'll look for tests related to
  redaction_tool.
✦ My apologies, I cannot use find. I will use rg instead.

✦ I see redaction_tool_unittest.cc in the results. This looks like the
  correct test file. I will run the components_unittests binary with a
