 ## Layout
 
+Every supported Minecraft version (1.21.4 to 1.21.11) builds from one copy of the version-specific code with [Stonecutter](https://stonecutter.kikugie.dev/):
+
 - `common/`: all version-independent code (mods, UI, cosmetics, the server client). It has no Minecraft dependency and reaches the game only through the interfaces in `org.saturnclient.common`.
-- `versions/<mc>/`: one module per Minecraft version, implementing those interfaces (providers, refs, mixins). Each is a full copy, and they differ only where Minecraft's API differs.
-  - `gradle.properties`: the Minecraft, Yarn, Fabric Loader and Fabric API versions.
-  - `src/`: the version-specific code and the three mixin configs.
+- `src/`: the version-specific code (providers, refs, mixins and the three mixin configs), one copy for every version. Where Minecraft's API differs between versions, the code goes behind version comments (see below).
+- `versions/<mc>/`: each version's `gradle.properties` (Minecraft, Yarn, Fabric Loader and Fabric API versions), plus its `build/` and `run/` folders. Each version is the Gradle project `:<mc>`.
 
-`settings.gradle` includes every folder under `versions/` automatically, as the Gradle project `:mc-<mc>`.
+`settings.gradle.kts` lists the versions in `stonecutterVersions`. The root `build.gradle.kts` builds each version, and `stonecutter.gradle.kts` configures the root project (shared repositories, the `common` wiring and `buildAll`). Loom's version is `loom_version` in the root `gradle.properties`.
 
-## Porting a change to the other versions
+## Version-specific code with Stonecutter
 
-Make the change in one version, usually the newest, then run:
+The code in `src/` is always plain Java for the **active** version (1.21.11, set in `stonecutter.gradle.kts`). Code for other versions sits in comments that Stonecutter swaps before building each version:
 
-```sh
-scripts/port.sh                        # port uncommitted changes to every other version
-scripts/port.sh --dry-run              # see what would apply cleanly first
-scripts/port.sh --to 1.21.9,1.21.10    # only some versions
-scripts/port.sh --commit <rev>         # port what a commit changed instead
+```java
+//? if >=1.21.9 {
+public void render(MatrixStack matrices, OrderedRenderCommandQueue queue, int light, PlayerEntityRenderState state, float limbAngle, float limbDistance) {
+//?} else
+//public void render(MatrixStack matrices, VertexConsumerProvider consumers, int light, PlayerEntityRenderState state, float limbAngle, float limbDistance) {
 ```
 
-The script applies the diff under `versions/<from>/src` to each other version with `git apply --3way`:
+A condition without braces covers the next line only. For several lines, use braces and wrap the inactive block in `/* … */`:
 
-- **applied**: the files matched, and nothing else is needed.
-- **CONFLICTS**: that version's code really differs. The file gets normal conflict markers, with the version's own code in `ours` and the ported change in `theirs`. Adapt the change to that version's API and resolve.
-- **already has this change**: nothing to do, which is safe to see when re-running.
+```java
+//? if >=1.21.11 {
+import net.minecraft.client.render.RenderLayers;
+import net.minecraft.client.render.RenderSetup;
+//?} else {
+/*import net.minecraft.client.render.RenderPhase.Textures;
+*///?}
+```
 
-Only `src/` is ported. `build.gradle` and `gradle.properties` are version-specific on purpose. Then build everything:
+Stonecutter rewrites inactive code into its own layout when switching versions (a single inactive line becomes `//code`), so write it that way to begin with, or run a switch and a reset before committing.
+
+When a newer version leaves something out that an older one implements, keep the older version's code behind a condition and mark the newer branch with a `TODO`, rather than dropping it for every version. `WorldFeatureImpl.getWorldAge` and `SaturnScreenFabric.resize` are examples. Search for `TODO` to find what newer versions still lack.
+
+A whole class that only exists for some versions (such as `NametagsMixin`, which hooks a method that 1.21.9 changed) can keep an empty class body on the other versions. An empty mixin changes nothing, and it keeps the mixin configs the same for every version, since JSON can't hold version comments.
+
+Inactive code sits inside a `/* … */` comment, so it can't contain `/* … */` comments itself: use `//` comments in code that's only active for some versions. For the same reason, don't nest multi-line version blocks; use `//?} else if <condition> {` for more than two version ranges, as in `PlayerEntityRendererMixin` and `SaturnRenderState`.
+
+- `./gradlew "Set active project to <mc>"` (or the Stonecutter IntelliJ plugin) rewrites `src/` so that version's code is the uncommented one, for editing it in the IDE.
+- `./gradlew "Reset active project"` switches back to 1.21.11. **Run it before committing**, so `src/` is always committed with 1.21.11 active.
+- Each version's processed copy is compiled from `versions/<mc>/build/generated/stonecutter/`, which is also where to look when a non-active version fails to compile.
+
+The `emotes` repository uses the same setup, and its `BentCubeRenderer` and `PlayerModelMixin` are small examples of version comments.
+
+## Checking a change on every version
+
+Since every version shares `src/`, a change applies to all of them at once. Code that uses the Minecraft API may still only compile on some, so build them all:
 
 ```sh
 ./gradlew compileJava
 ```
 
-The **Check** workflow runs the same compile on every pull request, so a version that was missed or mis-ported fails before merging.
+The **Check** workflow runs the same compile on every pull request, so a version a change doesn't compile on fails before merging. Mixins whose target changed fail at startup rather than at compile time, so launch the versions a change touches with `./gradlew :<mc>:runClient`.
+
+For bigger changes, `./gradlew buildAll` builds every version's jar into `build/allJars/`.
 
 ## Adding a Minecraft version
 
-1. Copy the closest existing version: `cp -r versions/1.21.11 versions/<new>`. Delete its `build/`, `.gradle/` and `run/` folders if present.
-2. In `versions/<new>/gradle.properties`, set `minecraft_version`, `yarn_mappings`, `loader_version` and `fabric_api_version`. The right values are listed at <https://fabricmc.net/develop>.
-3. Build it with `./gradlew :mc-<new>:compileJava` and fix what Minecraft changed. Check the mixin configs in `src/main/resources/*.mixins.json` as well: a mixin whose target changed fails at startup, not at compile time, so launch it with `./gradlew :mc-<new>:runClient`.
-4. The release workflow builds every folder under `versions/`, and "Publish to Modrinth" takes the game version from each jar's name, so neither needs changing.
+1. Create `versions/<new>/gradle.properties` with `minecraft_version`, `yarn_mappings`, `loader_version` and `fabric_api_version` (copy 1.21.11's and change the values; they're listed at <https://fabricmc.net/develop>). Loom's version is shared, in the root `gradle.properties`.
+2. Add `<new>` to `stonecutterVersions` in `settings.gradle.kts`.
+3. Build it with `./gradlew :<new>:compileJava` and put what Minecraft changed behind version comments. Check the mixin configs in `src/main/resources/*.mixins.json` as well: a mixin whose target changed fails at startup, not at compile time, so launch it with `./gradlew :<new>:runClient`.
+4. The release workflow builds everything through `buildAll`, and "Publish to Modrinth" takes the game version from each jar's name, so neither needs changing.
