The repositories moved from ludovic111 to the horizon-rust organization.
GitHub redirects repository URLs but not GitHub Pages, so the mod index
moved to https://horizon-rust.github.io/horizon-mods/: the launcher and
the game read it there. The launcher still accepts icons and files from
the old addresses, which a mirror keeps serving for launchers released
before the move.
Release notes thanked ludovic111 once the repository's owner became the
organization (verify failed on main): the maintainer is now named.

render.set-far-terrain moves to API level 7: main added levels 4 to 6
(world, recipes, browser) since this branch started.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A mod can now turn on the game's distant terrain (LOD) with
render.set-far-terrain: a distance of 64 to 1024 chunks and Far Detail's
Reduced. The game builds and draws the tiles as it does for the LOD
Distance setting, which wins while it is on. One far terrain shows at a
time, the first loaded mod's. API level 4.
mods/official/far-view is the official mod on it: Distance (256 chunks by
default) and Far detail on its settings page, kept in its storage.
Every item sits in the item panel beside the inventory and container
screens, with a search box (words in the name or id, @namespace, #tag).
R or a click shows an item's recipes, U or a right click its uses, with a
tab per station; Back returns through the pages. + beside a crafting
recipe the player knows fills the grid as the recipe book does. In
creative mode, with "Click gives items" on, a click gives one item and a
right click a stack. The keys are rebindable in Controls.
Written from vanilla 26.3's recipe book and screens and Horizon's design
system only. On servers that are not Horizon it shows the game's own
26.3 recipes; known recipes and + follow the server's recipe book.

recipes.place(book-id, all) is the recipe book's click: in the open
inventory's or crafting table's grid it sends ServerboundPlaceRecipePacket
on a server, or places it in this world, refused as handlePlaceRecipe
refuses it (no crafting screen, a recipe the player's book doesn't hold, an
impossible one); a recipe missing items shows as a ghost. recipes.give(stack)
gives a creative player the stack as the creative inventory does; a server
hears it as SetCreativeModeSlot through the inventory's sync. Both answer at
once from the tick's snapshot (placing, creative, known) and take at most 36
calls a hook call.

A mod gives the recipes to show (a layout: crafting grid, cooking, single
input, smithing or brewing; the slots, each cycling through its stacks;
the results; a note; and an optional action button, enabled or greyed)
under a title; an empty list shows the items again. The game pages them
and sends the slot-clicked, action, page and back events.
At most 256 recipes, 9 slots each and 64 stacks a slot. Same level as the
rest of browser (5): none of it has shipped yet.

A new interface under capability ui. browser.set-items lists the items of
a panel the game shows right of the inventory and container screens (an
empty list hides it); browser.poll returns what the player did since the
last poll: a click on an item, the search text, or one of the mod's own
keys pressed over an item (a slot's or the panel's), with that stack. The
slot-clicked, action, page and back events are there now for the recipe
pages to come, since adding variant cases later would break mods.
At most 8192 items and 256 waiting events. The game side is the next PR.

recipes.items() lists every item in registry order, with its name in the
player's language and its tags. recipes.all() lists every recipe: crafting
and furnace ones from the recipe book's own entries (vanilla's displays and
display ids), then campfire, stonecutting, smithing and brewing (display
only). Stacks point into the item table by index. recipes.known() gives the
book ids the player's recipe book holds, from the client book in every mode,
so on a server it follows the server's book.
The game builds the tables once, the first time a running mod reads them.
Experimental, new functions only. Smithing::Transform now keeps its recipe
id.

🤖 Agent: merged main (aec52c85e). pr_ready --quick passes (1308 horizon-client tests, clippy, 507 LOC). The welcome server mod e2e passes 35/35 in every mode: in-frame, server thread, LAN host in-frame and on its thread with a guest, dedicated with a guest. Verify is green; parity now runs on main (parity-scope). Queued.
A mod hands `run-quiet` a list of lines (at most 256 a call). In single
player they run as the player typing them would, with the player's source
made silent; on a Horizon server (it announces horizon:quiet_commands) they
go as one payload that the server runs the same way; on any other server
they fall back to chat commands, whose feedback shows. command.run is
unchanged.

- The list shows each project's rating (stars, mean and count) and its
downloads ("12.3k downloads"), ordered by downloads by default; an Order
menu also sorts by rating or name (?sort= too).
- A project's page shows the same, then a rating control: five stars when
signed in (the account's own rating lit), "Sign in with GitHub to rate"
(coming back to the page) when not, a note for its owners.
- Ratings come from the registry service's GET /api/mods/ratings; a rating
is POSTed with the session's CSRF token. Until the service answers, the
pages show downloads only.

🤖 Agent: game.raycast, mod API level 2. CI is green on c23b4e8e4. In game, in-frame and on the server thread, the ui guest's /raycast passes all four checks: glass at 2 blocks, nothing at 1, gold after /setblock, the sky is no hit. The ported Orbital Laser aims with it and fires in both modes. Queued.
🤖 Agent: The test scripts for server mods. CI is green on d64bd7c52, and the PR is now based on main after #1833 merged. I ran pr_ready --quick on this head merged with main (b8027d4b1): fmt, clippy, the horizon-mods and welcome tests (48) and the launcher tests (132) all pass. The only affected harness is lan_integration, which runs in CI. Queued.
`game.raycast(distance)` returns the first block along the player's view
(fluids pass), up to 1024 blocks: through the loaded chunks as the
crosshair's ray goes, then across the distant terrain's ground heights
(`Lod::ground`, from Stink-O's fork). The game casts it only while a running
mod imports the function. It is API level 2, so older Horizons refuse a mod
that calls it with "update Horizon".

Every function the game offers mods has the API level it arrived at
(crates/horizon-mods/src/api_level.rs): level 0 is the contract of
Horizon 0.2.67 and 0.2.68, level 1 adds render.set-minimap. A mod needs
the level of the newest function it imports, read from its component.
- The game refuses a mod that calls a function it doesn't have with
"made for a newer Horizon (it uses ...): update Horizon to run it"
instead of wasmtime's linking error.
- The registry index lists each mod version's level (api_level, read
from the file by CI); check_file compares it when the entry has one,
and the moved extras' installer takes the newest version this game
can run.
- cargo horizon-mod check prints the level.
- The api_reference test fails until a new WIT function has a level.

The minimap extra as a mod (mods/official/minimap): the extra's five
options on its settings page, kept in its storage with the extra's values
(corner, size, shape, zoom, rotate), and the map drawn by the game
through render.set-minimap, so it looks and costs the same.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
What the official Minimap mod needs: a mod picks the corner, side, scale,
shape and turning, and the game draws the map as the minimap extra does,
from the same tiles (vanilla's map colours, the floor under roofs) within
its own frame budget. One map at a time, the first loaded mod's. A new
function and type, so mods built before it keep loading.

🤖 Agent: cargo horizon-mod test runs a mod's test scripts with no game. Main is merged in, and the runner fills the new snapshot fields (input, render, frame stats) with the trial run's screen size. Verified: clippy, the cargo-horizon-mod, coords-hud and horizon-mods tests (57), launcher, and cargo horizon-mod test on coords-hud (2 scripts).
🤖 Agent: Horizon's official FPS Counter and Keystrokes as mods in mods/official/, same options and look as the extras (pixel-identical, frame cost within noise). Main merged in (wasmtime 48). Verified: pr_ready, clippy and tests of both mods, horizon-mods tests, both mods' settings pages in game.
A new case in ui's widget variant stops every ui mod built before it from
loading: the runtime links a component only when each imported
function's types match exactly ("expected variant of 5 cases, found
4"), so the published FPS Counter and Keystrokes would break. Instead,
the game lists a mod's keys first on its page in Options > Mods, as Key
Binds rows, and a mod with keys gets a page even without ui. No WIT
type changes. docs/api/stability.md said a new case the mod sends isn't
breaking; it is, and now says so.

🤖 Agent: Mod API (experimental): render.set-zoom and input.claim-wheel, held mod keys let go when a screen opens, mod keys on mouse buttons. The consume choice is in stability.md. Verified: pr_ready (1300 tests), sandbox tests, in game 22/22 in-frame and on the server thread.
mods/official/zoom: hold the key (Z) to zoom in at the starting zoom,
the wheel changes it while held (x1.25 a step, 1.25 to 10), smooth
easing and slower turning as options. Same settings page as the extra,
with the key widget for the key. Built on render.set-zoom,
input.claim-wheel and ui's key widget.

🤖 Agent: Mod API calls the official HUD mods use: render corner panels, text width and frame stats; input mappings and clicks per second; a ui button widget. Main merged in (after #1914's widget refactor). Verified: horizon-mods tests, clippy with and without mods, horizon-client tests (1121 lib), Keystrokes' settings page in game.
A ui page's key widget shows one of the mod's keys as Key Binds does
("Zoom: Z"). A click waits for the next key or mouse button, which
becomes the key; Esc binds none. The game keeps the choice in
horizon-mods.txt (key.<mod>.<name>:key.keyboard.z), applies it when
the mods load and to keys registered later, and lets a held key go when
it is rebound. register-key's key is now the default.
