+# Mod policy
+
+This registry lists mods, modpacks and packs for [Horizon](https://github.com/horizon-rust/horizon). This page says
+who makes them, who is responsible for them, and how to have one removed. By submitting to the registry you accept it.
+
+## Who makes the mods
+
+- **Mods made by the Horizon project** are marked **Official**: their author is "Horizon" and their source is in a
+  [horizon-rust](https://github.com/horizon-rust) repository. They are the only mods the Horizon
+  project makes and is responsible for.
+- **Every other mod is made, owned and maintained by its own authors**, named on its page. The Horizon project and
+  its maintainers are not their authors. They don't own these mods, sell them, or license them to you; each mod's
+  licence is the one its authors chose.
+- **A listing is not an endorsement.** Reviewers check that an entry is complete, that its files match their pinned
+  hashes, that it builds or loads against the Horizon version it names, and that nothing obviously harmful is in it.
+  That review is not a legal review, a security audit or a guarantee. Mods are provided as they are, without
+  warranty, by their authors.
+- **Native mods** (built into the game with [horizon-mixins](https://github.com/horizon-rust/horizon-mixins)) run
+  with the same access to your computer as the game. Install them only from authors you trust.
+
+## What authors promise when they submit
+
+Submitting a project, through the form or a pull request, means you confirm that:
+
+1. You made it, or you have the right to publish it, under the licence its entry names.
+2. **If it is a port or a translation of another mod** (for example from Java Edition), the original's licence allows
+   that, or its authors gave you permission. You keep the original's copyright and licence notices, and you credit
+   its authors and link the original on your page. A port of a mod whose licence reserves all rights needs its
+   authors' written permission.
+3. It contains no code, assets or data from Minecraft, Mojang or Microsoft beyond what their
+   [usage guidelines](https://www.minecraft.net/usage-guidelines) and EULA allow. Horizon players bring their own
+   copy of the game.
+4. It contains nothing that harms players: no malware, no stealing of accounts or data, no hidden network access.
+5. The `source` link has the code the published files were built from.
+
+You alone are responsible for what you publish and for any claim about it. The Horizon project may refuse, hide or
+remove any project, at any time, without having to give a reason.
+
+## Copyright and takedowns
+
+If a project in this registry uses your work without your permission:
+
+- [Open a takedown request](../../issues/new?template=takedown.yml) (public), or
+- write privately to the maintainer through [lu4ovic.com](https://lu4ovic.com/#contact).
+
+Say which project, which of your work it uses, and how to reach you. A claim that holds gets the project removed and
+listed in [`revoked.toml`](revoked.toml): the registry stops listing it and the launcher stops offering it and turns
+installed copies off. Clear claims are acted on quickly. The project's author is told, and can answer the claim in the
+same issue.
+
+Authors whose project was removed by mistake can ask for it back in that issue.
+
+## Changes
+
+This policy can change. The version in this repository's `main` branch is the one that applies.

+
+Native source mods (`.hnmod`, kind `native-mod`) are built into an isolated game by

+Their bundles pin the exact Horizon and Horizon Mixins revisions used for the build.
+Other revisions have not been validated. Registry checks inspect the source bundle without

+An item and recipe viewer for [Horizon](https://playhorizon.dev), the Rust reimplementation of Minecraft: Java Edition.
+
+Horizon JEI is inspired by [JustEnoughItems (JEI)](https://github.com/mezz/JustEnoughItems). JEI serves as the reference specification, while this project is a completely new Rust implementation built around Horizon's native hook points.
+
+**Version 0.1.0 — Core Viewer**
+
+### Features
+
+- **Item Browser:** Browse every item registered by the game through a paginated panel alongside container screens, with a search bar supporting JEI's search grammar: words, `"quoted phrases"`, `-exclusions`, `|` alternatives, `@namespace`, and `#tag`.
+- **Recipe Viewer:** Press **R** to view an item's recipes or **U** to see its uses. Both work over the item panel and container slots.
+- **Recipe Categories:** Dedicated tabs for crafting, furnace, blast furnace, smoker, campfire, stonecutter, smithing, and brewing, supporting all five of the game's recipe layouts, including cooking time and XP.
+- **Recipe Navigation:** Browse recipe history with **Back** and click recipe slots to open the corresponding item.
+- **Recipe Placement:** Use the **+** button to place a recipe into the open crafting grid, provided it is available in the recipe book.
+- **Item Giving:** Give items through Options → Mods → JEI or `/jei give`. In creative mode, left-click gives one item and right-click gives a full stack. In survival mode, clicking opens the recipe viewer instead.
+- **Localization:** English and Spanish interface translations. Item names are retrieved directly from the game and respect the player's language.
+- **Diagnostics:** `/jei` reports the game's recipe table sizes.
+
+### Current Limitations
+
+The 0.1.0 release focuses on the core viewer. Bookmarks, container slot click integration, tooltips, creative inventory integration, non-recipe categories (anvil, grindstone, composter, and fuel), and shift-click recipe placement are not yet supported.
+
+Some of these features require native hook points that Horizon does not currently expose. See the [JEI parity matrix](https://github.com/enderliker/horizon-jei/blob/main/docs/jei-parity.md) for implementation details.
+
+### Requirements & Security
+
+Requires Horizon **26.3**, hook points version **2**, and the current Nightly build.
+
+Horizon native mods are compiled directly into the game and are **not sandboxed**. Only build source code you trust.
+
+Horizon JEI reads the game's tables, container interface, chat, and its own settings directory (`horizon-mods/.horizon-mod-data/jei/`). It does not write to any other location.

+description = """
+Serverify is a server browser. Press **F8** (or type `/serverify web`, or press the button on the mod's settings page) and your web browser opens a page with a search box, a category menu and cards showing each server's picture, address, player count and country. Press **Add** and the server goes to the top of your Multiplayer list. Then join it from Horizon's own Multiplayer screen.
+
+It is the Horizon version of [Serverify](https://github.com/Louchatfroff/serverify), the server browser for Fabric, Quilt, Forge and NeoForge, by the same author.
+
+## What it does
+
+- Opens a server browser page in your web browser: search, 22 categories, an offline-mode filter and an **Add** button.
+- Adds servers to `servers.dat` in the game folder, with the name cleaned of colour codes.
+- Adds chat commands: `/serverify web`, `list [category]`, `search <words>`, `next`, `prev`, `add <number>` and `categories`.
+- Adds a row in Options > Mods with a rebindable key (F8 by default) and a settings page with two buttons: open the browser, and **Offline-mode servers only** (on by default).
+
+Horizon cannot join servers that check Minecraft accounts yet, which is most public servers, so by default the page shows servers that accept offline-mode players. Turn the filter off to see all of them.
+
+## What it contacts
+
+- **Modrinth.** The game asks `api.modrinth.com` for the server list and `cdn.modrinth.com` for server pictures, only when you look for servers.
+- **Three listing sites.** With the offline-mode filter off (and for top-mc-servers.net's list of cracked servers when it is on), the game fetches public pages of `top-mc-servers.net`, `minecraftservers.org` and `minecraft-mp.com`, and their server pictures. The game builds those addresses itself. The page reads the fetched pages with the browser's own HTML parser.
+- **A page on your computer.** The first time you open the page, the mod starts a small web server on `127.0.0.1` (this computer only, never the network) with a random secret in its address, made for each session. The page talks only to that server. A request with another host name, another origin or no secret is refused. The server can show the list, send a picture and add one server to your Multiplayer list.
+- It sends no data about you, and makes no request at any other time.
+
+## What it does not do
+
+- It does not run any code from the sites it reads, and it does not send your data anywhere.
+- It does not change anything but `servers.dat` (one entry at a time) and its own settings in `horizon-mods/.horizon-mod-data/serverify/`.
+- It does not draw screens or buttons in the game: Horizon's hook points have none, so the screen is your web browser.
+- It cannot make Horizon join servers that check Minecraft accounts.
+- Adding a server rewrites `servers.dat`, which drops the hidden direct-join entries Horizon keeps. Your saved servers stay.
+
+## Install

+# Coordinates HUD (Horizon native mod)
+
+Your block position and the direction you face in a box in the top-left corner of the screen.
+
+- `/where` puts your coordinates and dimension in chat.
+- `/coords` hides or shows the box, and the game keeps your choice (also Options > Mods > Coordinates HUD > Settings).
+
+It is a [horizon-mixins](https://github.com/horizon-rust/horizon-mixins) bundle (`mixins/coords_hud/`) that the Horizon
+launcher builds into the game. It replaces the WebAssembly Coordinates HUD 0.1.0, the WebAssembly SDK's example mod.
+The time of day line is gone: Horizon's hook points don't give the game's clock yet.
+
+## Install
+
+In the Horizon launcher: Mods → Coordinates HUD → Install, then Settings → Game → Native mods (experimental) → Build. The
+launcher downloads its own Rust and builds the game with your native mods; see Horizon's
+[native mods](https://github.com/horizon-rust/horizon/blob/main/docs/native-mods.md).
+
+## Made on the hook points
+
+The bundle hooks only Horizon's native hook points (`crates/horizon-client/src/game/native_hooks.rs`), which keep
+their names and signatures across releases. `compatibility.json` names the version it needs (`"hooks": 1`), so the
+launcher builds it on any Horizon with that version or a later one, together with any other mod. `horizon_revision` is
+only the commit it was last tested on.
+
+| File | What it is |
+|---|---|
+| `mixins/coords_hud/horizon-mixin.toml` | The bundle: one module and the HEAD hooks |
+| `mixins/coords_hud/runtime.rs` | The mod's logic and state, added to the game as `game::official_coords_hud`; also this crate's library, for its tests |
+| `mixins/coords_hud/*.rs` | One small helper per hook |
+| `proof.py` (with `../tools/game.py`) | The proof: the built game driven with `horizon-ctl --offscreen` on fresh, temporary data |
+
+## Build and prove
+
+```sh
+(cd native/coords-hud && cargo test)                     # the logic
+python3 native/tools/native.py check coords-hud          # apply on the tested Horizon and cargo check the game
+python3 native/tools/native.py check all                 # with the other native mods, as a player's set
+python3 native/tools/native.py package coords-hud        # native/target/coords_hud-<version>.hnmod for the registry
+python3 native/tools/native.py proof coords-hud --resources /path/to/.local/horizon-client/26.3
+```
+
+The proof needs resources prepared from your own Minecraft 26.3 (`horizon-prepare`); none are in this repository.
+It checks the row and the settings page in Options > Mods, that the box shows in the top left, that `/coords` hides it
+and writes `horizon-mods/.horizon-mod-data/coords_hud/shown`, and takes a screenshot of `/where`'s line in chat.

+# FPS Counter (Horizon native mod)
+
+Horizon's official FPS counter: frames per second in a box in a corner of the screen, and, if you like, the slowest frame and the 1% low of the last 5 seconds. Its settings page (Options > Mods > FPS Counter > Settings) picks the corner and the lows.
+
+It is a [horizon-mixins](https://github.com/horizon-rust/horizon-mixins) bundle (`mixins/fps_overlay/`) that the Horizon
+launcher builds into the game. It replaces the WebAssembly FPS Counter 1.x and keeps its settings: the same files (`horizon-mods/.horizon-mod-data/fps_overlay/corner`, `lows`).
+
+## Install
+
+In the Horizon launcher: Mods → FPS Counter → Install, then Settings → Game → Native mods (experimental) → Build. The
+launcher downloads its own Rust and builds the game with your native mods; see Horizon's
+[native mods](https://github.com/horizon-rust/horizon/blob/main/docs/native-mods.md).
+
+## Made on the hook points
+
+The bundle hooks only Horizon's native hook points (`crates/horizon-client/src/game/native_hooks.rs`), which keep
+their names and signatures across releases. `compatibility.json` names the version it needs (`"hooks": 1`), so the
+launcher builds FPS Counter on any Horizon with that version or a later one, the player's own game by default, together with any other
+mod. `horizon_revision` is only the commit it was last tested on.
+
+| File | What it is |
+|---|---|
+| `mixins/fps_overlay/horizon-mixin.toml` | The bundle: one module and the HEAD hooks |
+| `mixins/fps_overlay/runtime.rs` | The mod's logic and state, added to the game as `game::official_fps_overlay`; also this crate's library, for its tests |
+| `mixins/fps_overlay/*.rs` | One small helper per hook |
+| `../tools/native.py` | Shared by the native mods: apply on Horizon (from GitHub, by commit), check, build, package the `.hnmod`, run the proof |
+| `proof.py` (with `../tools/game.py`) | The proof: the built game driven with `horizon-ctl --offscreen` on fresh, temporary data |
+
+## Build and prove
+
+```sh
+(cd native/fps-overlay && cargo test)                    # the logic
+python3 native/tools/native.py check fps-overlay   # apply on the tested Horizon and cargo check the game
+python3 native/tools/native.py check fps-overlay --horizon latest  # ... on the newest Nightly
+python3 native/tools/native.py check all           # with the other native mods, as a player's set
+python3 native/tools/native.py package fps-overlay # native/target/fps_overlay-<version>.hnmod for the registry
+python3 native/tools/native.py proof fps-overlay --resources /path/to/.local/horizon-client/26.3
+```
+
+The proof needs resources prepared from your own Minecraft 26.3 (`horizon-prepare`); none are in this repository.
+It seeds the WebAssembly mod's settings (bottom right, lows on) in a temporary game folder, then checks that Options > Mods shows them, and that the Corner button moves the box to the top left and writes the same file. CI runs `cargo test`, packages the `.hnmod` and checks the game on the tested commit, and every Monday on the newest Nightly.

+# Keystrokes (Horizon native mod)
+
+Horizon's official Keystrokes: your movement keys, mouse buttons and space bar in a corner, lit while held, with clicks per second. Its settings page (Options > Mods > Keystrokes > Settings) picks the corner and the clicks per second.
+
+It is a [horizon-mixins](https://github.com/horizon-rust/horizon-mixins) bundle (`mixins/keystrokes/`) that the Horizon
+launcher builds into the game. It replaces the WebAssembly Keystrokes 1.x and keeps its settings: the same files (`horizon-mods/.horizon-mod-data/keystrokes/corner`, `cps`).
+
+## Install
+
+In the Horizon launcher: Mods → Keystrokes → Install, then Settings → Game → Native mods (experimental) → Build. The
+launcher downloads its own Rust and builds the game with your native mods; see Horizon's
+[native mods](https://github.com/horizon-rust/horizon/blob/main/docs/native-mods.md).
+
+## Made on the hook points
+
+The bundle hooks only Horizon's native hook points (`crates/horizon-client/src/game/native_hooks.rs`), which keep
+their names and signatures across releases. `compatibility.json` names the version it needs (`"hooks": 1`), so the
+launcher builds Keystrokes on any Horizon with that version or a later one, the player's own game by default, together with any other
+mod. `horizon_revision` is only the commit it was last tested on.
+
+| File | What it is |
+|---|---|
+| `mixins/keystrokes/horizon-mixin.toml` | The bundle: one module and the HEAD hooks |
+| `mixins/keystrokes/runtime.rs` | The mod's logic and state, added to the game as `game::official_keystrokes`; also this crate's library, for its tests |
+| `mixins/keystrokes/*.rs` | One small helper per hook |
+| `../tools/native.py` | Shared by the native mods: apply on Horizon (from GitHub, by commit), check, build, package the `.hnmod`, run the proof |
+| `proof.py` (with `../tools/game.py`) | The proof: the built game driven with `horizon-ctl --offscreen` on fresh, temporary data |
+
+## Build and prove
+
+```sh
+(cd native/keystrokes && cargo test)                    # the logic
+python3 native/tools/native.py check keystrokes    # apply on the tested Horizon and cargo check the game
+python3 native/tools/native.py check keystrokes --horizon latest  # ... on the newest Nightly
+python3 native/tools/native.py check all           # with the other native mods, as a player's set
+python3 native/tools/native.py package keystrokes  # native/target/keystrokes-<version>.hnmod for the registry
+python3 native/tools/native.py proof keystrokes --resources /path/to/.local/horizon-client/26.3
+```
+
+The proof needs resources prepared from your own Minecraft 26.3 (`horizon-prepare`); none are in this repository.
+It seeds the WebAssembly mod's settings (bottom right, no clicks per second) in a temporary game folder, then checks that Options > Mods shows them, and that the Corner button moves the keys to the top left and writes the same file. CI runs `cargo test`, packages the `.hnmod` and checks the game on the tested commit, and every Monday on the newest Nightly.
