 ## Layout
 
-Saturn is moving from one full copy of the version-specific code per Minecraft version to a single copy built with [Stonecutter](https://stonecutter.kikugie.dev/) (issue #8). During the move there are two kinds of version:
+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`.
-- `src/`: the version-specific code (providers, refs, mixins and the three mixin configs) for the versions built by Stonecutter, currently **1.21.6 to 1.21.11**. It's one copy: where Minecraft's API differs between them, the code goes behind version comments (see below). Each of these versions is the Gradle project `:<mc>`, and `versions/<mc>/` holds only its `gradle.properties` (Minecraft, Yarn, Fabric Loader and Fabric API versions), `build/` and `run/`.
-- `versions/<mc>/src/`: the versions not moved yet (1.21.4 and 1.21.5), each a full copy, as the Gradle project `:mc-<mc>` with its own `build.gradle`.

-`settings.gradle.kts` lists the Stonecutter versions in `stonecutterVersions` and includes every other folder under `versions/` as `:mc-<mc>`.

 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.

+A whole class that only exists for some versions (such as `MatrixStackMixin`, which only makes sense before 1.21.6's GUI rewrite) can keep an empty class body on the other versions. Before splitting a class like that, look for a hook that works on every version: nametags used to hook label rendering, which 1.21.9 changed, and now replace the name while the render state is built (`LivingEntityRendererMixin`), with no version condition at all. 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`.

-## Porting a change to the other versions
+## Checking a change on every version
 
-Make the change in one version, usually the newest, then run:
-
-```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 1.21.4,1.21.5     # only some versions
-scripts/port.sh --commit <rev>         # port what a commit changed instead
-```
-
-The script applies the diff under one version's source to each other version with `git apply --3way`. The Stonecutter `src/` counts as one version (1.21.11), so changes port between it and the old copies in both directions:
-
-- **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.
-
-Only source is ported. `build.gradle` and `gradle.properties` are version-specific on purpose. Then build everything:
+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
 
-Add new versions to Stonecutter rather than copying a folder:
-
 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`. When moving an existing `mc-<v>` version over instead, delete its `versions/<v>/src` and run `./gradlew :<v>:clean` once: the new project shares the old one's `build/` folder, and classes compiled from the removed sources would otherwise end up in the jar.
+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.
