 ## What to Contribute
 
 - Bug reports and fixes
     - We will generally accept bug fixes without too much question. If they are only implemented for one language, we will implement them for any other necessary languages. Bug reports are also welcome, please submit them to our GitHub issue tracker.
 - While we do welcome improvements to the API, there are a few important rules to consider:
-    - Features must be added to Java (WPILibJ), C++ (WPILibC), with rare exceptions.
-        - Most of Python (RobotPy) is created by wrapping WPILibC with pybind11 via robotpy-build. However, new features to the command framework should also be submitted to [robotpy-commands-v2](https://github.com/robotpy/robotpy-commands-v2) as the command framework is reimplemented in Python.
-    - During competition season, we will not merge any new feature additions. We want to ensure that the API is stable during the season to help minimize issues for teams.
-    - Ask about large changes before spending a bunch of time on them! You can create a new issue on our GitHub tracker for feature request/discussion and talk about it with us there.
+    - Features must be added to Java (WPILibJ), C++ (WPILibC), and Python with rare exceptions.
+        - Most of Python (RobotPy) is created by wrapping WPILibC with pybind11 via semiwrap. In general, new user-facing functions or classes should have the proper wrapper configs updated, typically located in a YAML file with the same name as the header. See the [in-repo RobotPy README](./README-RobotPy.md) for more info and how to partially auto-update the configs. However, the command framework is reimplemented in Python, and requires code to be ported instead of being wrapped via semiwrap.
+    - During competition season, we will not merge any new feature additions or removals. We want to ensure that the API is stable during the season to help minimize issues for teams.
+    - Ask about large changes before spending a bunch of time on them! See [Contribution Process](#contribution-process) for where to ask.
     - Features that make it easier for teams with less experience to be more successful are more likely to be accepted.
     - Features in WPILib should be broadly applicable to all teams. Anything that is team specific should not be submitted.
     - As a rule, we are happy with the general structure of WPILib. We are not interested in major rewrites of all of WPILib. We are open to talking about ideas, but backwards compatibility is very important for WPILib, so be sure to keep this in mind when proposing major changes.
-    - Generally speaking, we do not accept code for specific sensors. We have to be able to test the sensor in hardware on the WPILib test bed. Additionally, hardware availability for teams is important. Therefore, as a general rule, the library only directly supports hardware that is in the Kit of Parts. If you are a company interested in getting a sensor into the Kit of Parts, please contact FIRST directly at frcparts@firstinspires.org.
+    - While the library may contain support for specific sensors, these are typically items contained in the FIRST Robotics Competition Kit of Parts or commonly used hardware identified by FIRST or core WPILib Developers. If you think a certain sensor should be supported in WPILib, you may submit an issue justifying the reasons why it should be supported and approval will be determined by FIRST or core WPILib Developers. If you are a company interested in getting a sensor into the Kit of Parts, please contact FIRST directly at frcparts@firstinspires.org.
+
+## Design Philosophy
+
+WPILib's general design philosophy strays far away from the traditional Object-Oriented Programming architectures dominant in enterprise codebases. The general points to follow for WPILib are as follows:
+
+- Prefer functions and composition over inheritance. Inheritance is rigid and often prevents evolution, as adding or removing methods from an inherited class risks breakage. For similar reasons, functional interfaces (`std::function` in C++) are preferred over actual interfaces.
+- Avoid opaque black-boxes of functionality. Classes like RamseteCommand or HolonomicDriveController (both removed in 2027) are good examples of this. While they look like a good abstraction that helps beginners, the black-box nature means they are [difficult to debug](https://github.com/wpilibsuite/allwpilib/issues/3350) and it's impossible to instrument the internals to figure out what's going on, or they are extremely clunky to use compared to composing the individual components (thus defeating the point of abstracting it away; SwerveControllerCommand construction was [a huge pile of opaque arguments glued together](https://github.com/wpilibsuite/allwpilib/blob/v2026.2.2/wpilibjExamples/src/main/java/edu/wpi/first/wpilibj/examples/swervecontrollercommand/RobotContainer.java#L104-L114)). Composition is strongly preferred, with strong documentation and examples describing how to do that composition.
+- Error at compile time, not runtime. Despite our best efforts, there will always be people who don't read stack traces (understandable for beginner programmers). Compile time errors show up in builds and in an IDE, which is much easier and faster for people to pinpoint and debug. Use language features to make invalid code impossible to build.
+    - The Matrix class in Java is an example of this. While clunky due to Java's weak generics system, it enforces correct Matrix dimensions at compile time, with the MatBuilder factory method throwing if the array passed in is the wrong size, which leads to the next point:
+- Try to only throw exceptions at code startup, and only for things that are obviously incorrect. Robots shouldn't quit, and it's a real "feels bad" moment when yours does, especially in a match. It's oftentimes better to have a robot continue running when it sees nonsensical state as opposed to outright crashing, since other components are often still functional. If you can't make invalid code a compile time error, throwing at the start of the robot program is the next best solution, but avoid throwing in functions likely to be called throughout a robot's runtime.
+    - Sometimes the behavior of functions are just incorrect if invalid data is passed in, and throwing is one of the only options. This is a judgement call, but if there are no other options, throwing can be okay.
+        - An alternative to throwing is logging an error, typically with [the Alerts framework](https://docs.wpilib.org/en/latest/docs/software/telemetry/persistent-alerts.html); this is a good choice for runtime errors. Also see https://github.com/wpilibsuite/allwpilib/issues/6766 for an example of not throwing exceptions, but simply logging an error on invalid data.
+    - Note that hardware configuration issues such as a sensor not existing isn't necessarily obviously incorrect; it could be that the wrong port was specified, but it could also be unplugged due to external factors. Throwing just because it's unplugged can make for a "feels bad" moment, and should be avoided.
+
+## Contribution Process
+
+Have an idea to make WPILib better? Here's some steps to go from idea to implementation:
+
+1. (Optional) **Discuss it in the Discord.** The programming discussion channel in the [Unofficial FIRST Robotics Competition Discord Server](https://discord.com/invite/frc) is a popular choice for initial discussion about ideas because many WPILib developers are active there and the live messaging nature of the platform is well suited for initial discussion (particularly for smaller changes). Note that the unofficial Discord server is not a mandatory step in the development process and is not endorsed by FIRST®.
+2. (Recommended) **Open a GitHub issue.** GitHub issues are another way to get initial feedback about an idea before working on an implementation. Compared to the unofficial Discord server, GitHub issues have much wider visibility and are better suited for serious discussions about major changes. Getting feedback about an idea (whether in the unofficial Discord server or in a GitHub issue) before working on the implementation is recommended to avoid working on a change that will be rejected, though some ideas are pretty safe.
+3. (Rare) **Create a design document in GitHub.** Sometimes, a change is so large that a design document is necessary to fully flesh out the details (and get feedback on them) before starting on an implementation. This is done through a pull request that adds the design document (as a Markdown file) to the repository. This is extremely rare, and it is sometimes done concurrently with the implementation if the change doesn't need much debate but is large enough to require a design document.
+4. (Mandatory) **Create a GitHub pull request.** This is how you implement the changes, and is the focus of most of the rest of this document.
 
 ## Coding Guidelines
 
 WPILib uses modified Google style guides for both C++ and Java, which can be found in the [styleguide repository](https://github.com/wpilibsuite/styleguide). Autoformatters are available for many popular editors at https://github.com/google/styleguide. Running wpiformat is required for all contributions and is enforced by our continuous integration system.
 While the library should be fully formatted according to the styles, additional elements of the style guide were not followed when the library was initially created. All new code should follow the guidelines. If you are looking for some easy ramp-up tasks, finding areas that don't follow the style guide and fixing them is very welcome.
 
-### Math documentation
-
-When writing math expressions in documentation, use https://www.unicodeit.net/ to convert LaTeX to a Unicode equivalent that's easier to read. Not all expressions will translate (e.g., superscripts of superscripts) so focus on making it readable by someone who isn't familiar with LaTeX. If content on multiple lines needs to be aligned in Doxygen/Javadoc comments (e.g., integration/summation limits, matrices packed with square brackets and superscripts for them), put them in @verbatim/@endverbatim blocks in Doxygen or `<pre>` tags in Javadoc so they render with monospace font.
-
-The LaTeX to Unicode conversions can also be done locally via the unicodeit Python package. To install it, execute:
-```bash
-pip install --user unicodeit
-```
-
-Here's example usage:
-```bash
-$ python -m unicodeit.cli 'x_{k+1} = Ax_k + Bu_k'
-xₖ₊₁ = Axₖ + Buₖ
-```
-
-On Linux, this process can be streamlined further by adding the following Bash function to your .bashrc (requires `wl-clipboard` on Wayland or `xclip` on X11):
-```bash
-# Converts LaTeX to Unicode, prints the result, and copies it to the clipboard
-uc() {
-  if [ $WAYLAND_DISPLAY ]; then
-    python -m unicodeit.cli $@ | tee >(wl-copy -n)
-  else
-    python -m unicodeit.cli $@ | tee >(xclip -sel)
-  fi
-}
-```
-
-Here's example usage:
-```bash
-$ uc 'x_{k+1} = Ax_k + Bu_k'
-xₖ₊₁ = Axₖ + Buₖ
-```
-
 ## Submitting Changes
 
 ### Pull Request Format
 
 Changes should be submitted as a Pull Request against the main branch of WPILib. For most changes, commits will be squashed upon merge. For particularly large changes, multiple commits are ok, but assume one commit unless asked otherwise. We may ask you to break a PR into multiple standalone PRs or commits for rebase within one PR to separate unrelated changes. No change will be merged unless it is up to date with the current main branch. We do this to make sure that the git history isn't too cluttered.
 
-During the build season, breaking changes or other changes intended for the next season can be created as a pull request against the development branch of WPILib. After the season is over, the changes in the development branch will be merged into main.
+Particularly large and/or breaking changes should be targeted to the 2027 branch, which targets the [Systemcore Robot Controller](https://community.firstinspires.org/introducing-the-future-mobile-robot-controller). The intent is minimize changes for 2026, to allow development to focus on preparing for 2027.

If you regenerated the files and Git indicates the files have changed, but the diff doesn't show any changes, only the line endings have changed. If you expected changes to the generated code, you didn't correctly make changes. If you didn't expect changes, you can ignore this and discard the changes. Also ensure that you've marked the Python script as executable, since this is necessary for CI workflows to run your scripts. To add your script to the CI workflows, edit [.github/workflows/pregen_all.py](.github/workflows/pregen_all.py), and add your script alongside the rest of the scripts.
+
+#### (Re)Generating QuickBuffers files
+Regenerating QuickBuffers files requires the Protocol Buffers compiler (protoc), and the QuickBuffers plugin, which can be found on [their releases page](https://github.com/HebiRobotics/QuickBuffers/releases). Once you have both, you can pass their paths into the generation scripts with `--protoc` and `--quickbuf_plugin` and regenerate the files.

 ## Publishing Third Party Dependencies
-Currently the 3rd party deps are imgui, opencv, google test, libssh, and apriltaglib
+Currently the 3rd party external deps are opencv, libssh, ceres, and gtsam.
 
 For publishing these dependencies, the version needs to be manually updated in the publish.gradle file of their respective repository.
-Then, in the azure build for the dependency you want to build for, manually start a pipeline build (As of current, this is the `Run Pipeline` button).
-A variable needs to be added called `RUN_AZURE_ARTIFACTORY_RELEASE`, with a value of `true`. Then when the pipeline gets started, the final build outputs will be updated to artifactory.
+Then, upload a new tag for the dependency you want to build for, which will automatically start a build.
+The CI workflow should set `RUN_AZURE_ARTIFACTORY_RELEASE` to `true` on tagged runs. Then when the pipeline gets started, the final build outputs will be uploaded to artifactory.
 
 To use newer versions of C++ dependencies, in `shared/config.gradle`, update the version related to the specific dependency.
 For Java dependencies, there is likely a file related to the specific dependency in the shared folder. Update the version in there.
 
-Note, changing artifact locations (This includes changing the artifact year currently, I have an issue open to change this) requires updating the `native-utils` plugin
+Note, changing artifact locations requires updating the `native-utils` plugin; specifically, the `configureDependencies` method in the `WPINativeUtilsExtension` class.
 
 ## Publishing allwpilib
 allwpilib publishes to the development repo on every push to main. To publish a release build, upload a new tag, and a release will automatically be built and published.
 
-## Publishing desktop tools
-Desktop tools publish to the development repo on every push to main. To publish a release build, upload a new tag, and a release will automatically be built and published.

 ## Artifact classifiers
 We provide two base types of artifacts.
 
-The first types are Java artifacts. These are usually published as `jar` files. Usually, the actual jar file is published with no classifier. The sources are published with the `-sources` classifier, and the javadocs are published with the `-javadoc` classifier.
-
-The second types are native artifacts. These are usually published as `zip` files (except for the `JNI` artifact types, which are `jar` files. See below for information on this). The `-sources` and `-headers` classifiers contain the sources and headers respectively for the library. Each artifact also contains a classifier for each platform we publish. This platform is in the format `{os}{arch}`. The platform artifact only contains the binaries for a specific platform. In addition, we provide a `-all` classifier. This classifier combines all of the platform artifacts into a single artifact. This is useful for tools that cannot determine what version to use during builds. However, we recommend using the platform specific classifier when possible. Note that the binary artifacts never contain the headers, you always need the `-headers` classifier to get those.
-
-## Artifact Names
-
-WPILib builds four different types of artifacts.
-
-##### C++ Only Libraries
-When we publish C++ only libraries, they are published with the base artifact name as their artifact name, with a `-cpp` extension. All dependencies for the library are linked as shared libraries to the binary.
-
+The first types are Java artifacts. These are usually published as `jar` files. Usually, the actual jar file is published with no classifier. The sources are published with the `-sources` classifier, and the javadocs are published with the `-javadoc` classifier. These artifacts are published with the base artifact name as their artifact ID, with a `-java` extension.
 
 Example:
 ```
-edu.wpi.first.wpilibc:wpilibc-cpp:version:classifier@zip
+org.wpilib.wpilibj:wpilibj-java:version
 ```
 
-#### Java Only Libraries
-When we publish Java only libraries, they are published with the base artifact name as their artifact name, with a `-java` extension.
+The second types are native artifacts. These are usually published as `zip` files. The `-sources` and `-headers` classifiers contain the sources and headers respectively for the library. Each artifact also contains a classifier for each platform we publish. This platform is in the format `{os}{arch}`. The full list of supported platforms can be found in [native-utils in the Platforms nested class](https://github.com/wpilibsuite/native-utils/blob/main/src/main/java/org/wpilib/nativeutils/WPINativeUtilsExtension.java). If the library is built statically, it will have `static` appended to the classifier. Additionally, if the library was built in debug mode, `debug` will be appended to the classifier. The platform artifact only contains the binaries for a specific platform. Note that the binary artifacts never contain the headers, you always need the `-headers` classifier to get those.
+
+If the library is Java and C++ and has a JNI component, the native artifact will have a shared library containing JNI entrypoints alongside the C++ shared library. This JNI shared library will have a `jni` suffix in the file name.
+
+Native artifacts are published with the base artifact name as their artifact ID, with a `-cpp` extension.
 
 Example:
 ```
-edu.wpi.first.wpilibj:wpilibj-java:version
-```
-
-#### C++/Java Libraries without JNI
-For libraries that are both C++ and Java, but without a JNI component, the C++ component is published with the `basename-cpp` artifact name, and the Java component is published with the `basename-java` artifact name.
-
-Example:
-```
-edu.wpi.first.wpiutil:wpiutil-cpp:version:classifier@zip (C++)
-edu.wpi.first.wpiutil:wpiutil-java:version (Java)
-```
-
-#### C++/Java Libraries with JNI
-For libraries that are both C++ and Java with a JNI component there are three different artifact names. For Java, the component is published as `basename-java`. For C++, the `basename-cpp` artifact contains the C++ artifacts with all dependencies linked as shared libraries to the binary. These binaries DO contain the JNI entry points. The `basename-jni` artifact contains identical C++ binaries to the `-cpp` artifact, however all of its dependencies are statically linked, and only the JNI and C entry points are exported.
-
-The `-jni` artifact should only be used in cases where you want to create a self contained Java application where the native artifacts are embedded in the jar. Note in an extraction scenario, extending off of the library is never supported, which is why the C++ entry points are not exposed. The name of the library is randomly generated during extraction. For pretty much all cases, and if you ever want to extend from a native library, you should use the `-cpp` artifacts. GradleRIO uses the `-cpp` artifacts for all platforms, even desktop, for this reason.
-
-Example:
-```
-edu.wpi.first.ntcore:ntcore-cpp:version:classifier@zip (C++)
-edu.wpi.first.ntcore:ntcore-jni:version:classifier (JNI jar library)
-edu.wpi.first.ntcore:ntcore-java:version (Java)
+org.wpilib.wpimath:wpimath-cpp:version:classifier@zip
+org.wpilib.wpimath:wpimath-cpp:version:windowsx86-64staticdebug@zip
 ```

+When invoking Bazel, it will check if `user.bazelrc` exists for additional, user specified flags. You can use these settings to do things like always ignore builds in a specific folder, or limiting the CPU/RAM usage during a build.
 Examples:
 - `build --build_tag_filters=-wpi-example` - Do not build any targets tagged with `wpi-example` (Currently all of the targets in wpilibcExamples and wpilibjExamples contain this tag)
 - `build -c opt` - Always build optimized targets. The default compiler flags were chosen to build as fast as possible, and thus don't contain many optimizations
 - `build -k` - `-k` is analogous to the MAKE flag `--keep-going`, so the build will not stop on the first error.
 - ```
-  build --local_ram_resources=HOST_RAM*.5 # Don't use more than half my RAM when building
-  build --local_cpu_resources=HOST_CPUS-1 # Leave one core alone
+  build --local_resources=memory=HOST_RAM*.5 # Don't use more than half my RAM when building
+  build --local_resources=cpu=HOST_CPUS-1 # Leave one core alone
   ```
+Bazel's RAM usage estimation is simplistic and hardcoded, so limiting the allowed number of CPU cores is the best way to reduce memory usage if it becomes a problem.
+
+The default settings build all the release artifact variants relevant for your platform.  The overall list of options ends up being, essentially, all the variants of (linux, osx, windows) x (debug, release) x (static, shared) x (aarch64, x86).  OSX and Windows are hard to compile for from any other OS, so we by default build for your local OS and the system core, with all the variants.
+
+This can be a bit expensive.  If you would like to build a subset, you can specify the repo environmental variable, `WPI_PUBLISH_CLASSIFIER_FILTER`, and pick what you build for.  The default is, in the .bazelrc file,
+```
+common --repo_env="WPI_PUBLISH_CLASSIFIER_FILTER=headers,sources,linuxsystemcore,linuxsystemcoredebug,linuxsystemcorestatic,linuxsystemcorestaticdebug,linuxx86-64,linuxx86-64debug,linuxx86-64static,linuxx86-64staticdebug,osxuniversal,osxuniversaldebug,osxuniversalstatic,osxuniversalstaticdebug,windowsarm64,windowsarm64debug,windowsarm64static,windowsarm64staticdebug,windowsx86-64,windowsx86-64debug,windowsx86-64static,windowsx86-64staticdebug"
+```
+
+Modify this to your likings if you want to build less.
+
+## Pregenerating Files
+allwpilib uses extensive use of pre-generating files that are later used to build C++ / Java libraries that are tracked by version control. Quite often,
+these pre-generation scripts use some configuration file to create multiple files inside of an output directory. While this process could be accomplished
+with a `genrule` that would require an explicit listing of every output file, which would be tedious to maintain as well as potentially confusing to people
+adding new features those libraries. Therefore, we use `@aspect_bazel_lib` and their `write_source_files` feature to generate these directories. In the event that the generation process creates more than a small handful of predictable files, a custom rule is written to generate the directory.
+
+## Remote Caching
+One of the huge benefits of Bazel is its remote caching ability. However, due to Bazel's strict build definitions, it is hard to share remote cache artifacts between different computers unless our toolchains are fully hermetic, which means you are unlikely to be able to reuse the cache artifacts published from the `main` branch on your local machine like you might be able to with the `gradle` or `cmake` caches. Luckily, the GitHub Actions CI machines are generally stable between runs and can reuse cache artifacts, and your local machine should remain stable, so if you set up a free buildbuddy account you can have your fork's CI actions be able to use a personalized cache, as well as your local machine.
+
+For the main `allwpilib` upstream, the cache is only updated on the main branch; pull requests from forks will not be able to modify the cache. However, you can set up your fork to enable its own cache by following the steps below.
+
+### Setting Up API keys
+Follow the [buildbuddy authentication](https://www.buildbuddy.io/docs/guide-auth) guide to create keys. For your local machine, it is recommended that you place the following configuration line in either a `user.bazelrc` or `bazel_auth.rc` file in the repositories root directory.
+
+```
+build --remote_header=<your api key>
+```
+
+To get your forks CI actions using your own buildbuddy cache, follow [GitHub's](https://docs.github.com/en/actions/how-tos/security-for-github-actions/security-guides/using-secrets-in-github-actions) documentation for setting up a repository secret. The secrets key should be `BUILDBUDDY_API_KEY`, and the value should be your buildbuddy API key.

 ## Prerequisites
 
-The protobuf library and compiler are needed for protobuf generation.
-
 OpenCV needs to be findable by CMake. On systems like the Jetson, this is installed by default. Otherwise, you will need to build OpenCV from source and install it.
 
-If you want JNI and Java, you will need a JDK of at least version 17 installed. In addition, you need a `JAVA_HOME` environment variable set properly and set to the JDK directory.
-
-If you are building with unit tests or simulation modules, you will also need an Internet connection for the initial setup process, as CMake will clone google-test and imgui from GitHub.

If it's installed on the system, CMake may find it from PATH, but you will likely need to locate the JAR and manually give CMake the JAR directory. If you are on Linux, you will also need to add the path of the libraries to `LD_LIBRARY_PATH`. This can be done by prepending `LD_LIBRARY_PATH=/path/to/libraries` to the Java command. If you need to add more paths, separate them with colons. The final command should look like `java -cp "robot.jar:/path/to/library_jars/*" main.package.Main`, using a semicolon to separate paths instead of a colon if you are on Windows.

+# robotpy in allwpilib
+allwpilib hosts a mirror of RobotPy that can be built with Bazel on Linux. The intent of the mirror is to have breaking changes identified early and fixed by the PR creator so that when WPILib releases are made, there is much less work required to release a RobotPy version that wraps it. It is not a goal for allwpilib to replace the RobotPy repo; it will still be considered the "source of truth" for Python builds and will be responsible for building against all of the applicable architectures and multiple versions of Python.
+
+## Build Process
+The upstream RobotPy repository uses TOML configuration files and semiwrap to produce Meson build scripts. The allwpilib fork uses these TOML configuration files to auto-generate Bazel build scripts. In general, each project (wpiutil, wpimath, etc) defines two pybind extensions; one that simply wraps the native library, and another that adds extension(s) that and contains all of the Python files for the library. Both of these subprojects have auto-generated build files; a `robotpy_native_build_info.bzl` for the native wrapper and `robotpy_pybind_build_info.bzl` which defines the extensions and Python library.
+
+## Disabling RobotPy builds
+Building the RobotPy software on top of the standard C++/Java software can result in more than doubling the amount of time it takes to compile. To skip building the RobotPy tooling, you can add `--config=skip_robotpy` to the command line or to your `user.bazelrc`.
+
+# Syncing with RobotPy
+[Copybara](https://github.com/google/copybara) is used to maintain synchronization between the upstream RobotPy repositories and the allwpilib mirror. GitHub Actions can be manually run, which will create pull requests that will update all of the RobotPy files between the two repositories. The ideal process is that the allwpilib mirror is always building in CI, and once a release is created, the RobotPy team can run the `wpilib -> robotpy` Copybara task, make any fine tuned adjustments and create their release. In the event that additional changes are made on the RobotPy side, they can run the `robotpy -> wpilib` task to push the updates back to the mirror. However, the goal of the mirroring the software here is to be able to more rapidly test changes and will hopefully overwhelmingly eliminate the need for syncs in this direction.
+
+## Creating a user config
+The Copybara scripts needs to know information about what repositories it will be pushing the synced changes to. These can be specified on the command line, or you can create a `shared/bazel/copybara/.copybara.json` config file to save your personalized settings to avoid having to type things out every time. To run the full suite of migrations, you need a fork of [allwpilib](https://github.com/wpilibsuite/allwpilib), a fork of [mostrobotpy](https://github.com/robotpy/mostrobotpy), and a fork of RobotPy's [commands-v2](https://github.com/robotpy/robotpy-commands-v2). If you only wish to run a subset of commands (i.e. not sync the commands project), you do not need to include that in your user config.
+
+Example config:
+```json
+{
+    "mostrobotpy_local_repo_path": "/home/<username>/git/robotpy/robotpy_monorepo/mostrobotpy",
+    "mostrobotpy_fork_repo": "https://github.com/<username>/mostrobotpy.git",
+    "allwpilib_fork_repo": "https://github.com/<username>/allwpilib.git",
+    "robotpy_commandsv2_fork_repo":  "https://github.com/<username>/robotpy-commands-v2.git"
+}
+```
+
+## Running syncs
+- **Pulling changes from mostrobotpy**:
+
+    `python3 shared/bazel/copybara/run_copybara.py mostrobotpy_to_allwpilib`
+
+
+- **Pulling changes from the commands library**:
+
+    `python3 shared/bazel/copybara/run_copybara.py commandsv2_to_allwpilib`
+
+- **Pushing changes to the commands library**:
+
+    `python3 shared/bazel/copybara/run_copybara.py allwpilib_to_commandsv2`
+
+- **Pushing changes to mostrobotpy**:
+
+    This process is slightly more complicated, because you will almost certainly also need to update the Maven artifacts that mostrobopy is using. Because of this, you must also specify the version number that has been published to WPILib's Maven repository. If you are trying to get an early, non-released development build pushed over, you can also add the `--development_build` flag:
+
+    `python3 shared/bazel/copybara/run_copybara.py allwpilib_to_mostrobotpy --wpilib_bin_version=2027.0.0-alpha-3-86-g418b381 --development_build -y`
+
+# Debugging Build Errors
+The build process is highly automated and automatically parses C++ header files to generate pybind11 bindings. Some of these steps here are considered "pregeneration" steps, and the Bazel build system will update build files as necessary. If a new header is added, or if the contents of a header file has changed, some of the pregeneration scripts might need to be run. If you encounter an error building `robotpy` code, it is recommended that you go through these steps to make sure everything is set up correctly. The examples are for `wpilibc`, but similar build tasks and tests exist for each wrapped project.
+
+## 1. scan-headers
+This can be the first source of problems if a new header file has been added. `semiwrap` will look through all of the headers for a library and notify you if a file is not covered by the projects `pyproject.toml` file. Bazel has a test case to ensure the files are up to date.
+
+An example test failure when a new header being introduced. You can run the test with the following command:
+
+bazel run //wpilibc:robotpy-wpilib-scan-headers
+
+```
+# wpi
+ExpansionHub = "wpi/ExpansionHub.hpp"
+ExpansionHubCRServo = "wpi/ExpansionHubCRServo.hpp"
+ExpansionHubMotor = "wpi/ExpansionHubMotor.hpp"
+ExpansionHubPidConstants = "wpi/ExpansionHubPidConstants.hpp"
+ExpansionHubServo = "wpi/ExpansionHubServo.hpp"
+
+```
+
+To fix this, you can copy the lines from the console, and add them to the pyproject.toml file, located here `wpilibc/src/main/python/pyproject.toml`
+
+## 2. update-yaml
+This process parses all of the header files, and creates a representation of the classes / enums / etc in YAML. Occasionally, some functions might be ignored or need custom pybind code, which can be added to these files by the user.
+
+There is a Bazel task that you can run to automatically update the files:
+
+`bazel run //wpilibc:write_robotpy-wpilib-update-yaml`
+
+
+## 3. generate-build-info
+This step takes the yaml files, and auto-generates a Bazel build script for the library.
+
+There is a Bazel task that you can run to automatically update the files:
+
+`bazel run //wpilibc:robotpy-wpilib-generator.generate_build_info`
+
+## semiwrap errors
+If all of the above steps go smoothly and have their tests pass, but the generated cpp files still won't compile, it is possible that either an update needs to be made to the semiwrap tool to handle the new complex functionality, the new functionality can be ignored, or the new functionality might be better handled with a custom pybind11 implementation. In any case, it is best to reach out to the RobotPy team for guidance.
+
+## Running multiple projects at once
+Each project has its own `scan-headers` and various pregeneration tools, but you can run all of them at once with the following commands. Note: Sometimes if something in the dependency chain for a library fails, these amalgamation commands will also fail. If that happens, fix your way up the dependency chain project by project.
+
+```
+# Scan Headers
+bazel test //... -k --test_tag_filters=robotpy_scan_headers --build_tests_only
+
+# All pregen
+bazel run //:write_robotpy_files
+
+```

Shared code must be platform-independent, since it will be compiled with both the ARM cross-compiler and whatever desktop compiler you are using (g++, msvc, etc...).
+The main WPILib code you're probably looking for is in WPILibJ and WPILibC. Those directories contain the high-level hardware/robot classes used for interacting with hardware, the Driver Station, and contain the core framework that almost all robot projects use.
 
-The integration test directories for C++ and Java contain test code that runs on our test-system. When you submit code for review, it is tested by those programs. If you add new functionality you should make sure to write tests for it so we don't break it in the future.
+The src/test directories under each subproject for C++ and Java contain test code that runs on GitHub Actions. When you submit code for review, it is tested by GitHub Actions' runners. If you add new functionality you should make sure to write tests for it so we don't break it in the future.
 
-The hal directory contains more C++ code meant to run on the roboRIO. HAL is an acronym for "Hardware Abstraction Layer", and it interfaces with the NI Libraries. The NI Libraries contain the low-level code for controlling devices on your robot. The NI Libraries are found in the [ni-libraries](https://github.com/wpilibsuite/ni-libraries) project.
+The hal directory contains more C++ code meant to run on Systemcore. HAL is an acronym for "Hardware Abstraction Layer", and it interfaces with the robot controller to enable hardware interactions. The HAL is split into cpp, sim, and systemcore. The systemcore directory contains the WPILib code meant to run on your Systemcore. Sim is WPILib code meant to run on your computer, and cpp is code shared between the two. Code in the cpp directory must be platform-independent, since it will be compiled with both the ARM cross-compiler and whatever desktop compiler you are using (g++, MSVC, etc...).
 
 The upstream_utils directory contains scripts for updating copies of thirdparty code in the repository.

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Moe Ghoul>, 1 April 1990
+  Moe Ghoul, President of Vice
+
+That's all there is to it!

- * Class for representing a layout of AprilTags on a field and reading them from a JSON format.
- *
- * <p>The JSON format contains two top-level objects, "tags" and "field". The "tags" object is a
- * list of all AprilTags contained within a layout. Each AprilTag serializes to a JSON object
- * containing an ID and a Pose3d. The "field" object is a descriptor of the size of the field in
- * meters with "width" and "length" values. This is to account for arbitrary field sizes when
- * transforming the poses.
- *
- * <p>Pose3ds in the JSON are measured using the normal FRC coordinate system, NWU with the origin
- * at the bottom-right corner of the blue alliance wall. {@link #setOrigin(OriginPosition)} can be
- * used to change the poses returned from {@link AprilTagFieldLayout#getTagPose(int)} to be from the
- * perspective of a specific alliance.
- *
- * <p>Tag poses represent the center of the tag, with a zero rotation representing a tag that is
- * upright and facing away from the (blue) alliance wall (that is, towards the opposing alliance).
