playhorizon.dev now deploys from the private ludovic111/horizon-site, which holds website/'s history. The files
its build still reads from here move out of website/:
- the design tokens to crates/horizon-theme/tokens.css (xtask tokens writes them, tokens_css_is_up_to_date checks them);
- the roadmap's JSON to roadmap/roadmap.json (tools/roadmap.py build);
- the benchmark fixtures to crates/horizon-telemetry-server/tests/fixtures/benchmarks/ (the site keeps a copy);
- the web icons to docs/media/brand/web/ (xtask icons).
pr_ready loses its website area and the tokens special case; rust_changes, the roadmap's links and every doc
that pointed into website/ follow.

A developer of Iris showed that Horizon's shader pack code was written from
Iris's source. This removes it: the horizon-shaderpack crate, Java pack
loading and its render stages, Horizon's own WGSL packs and the example
packs, the Shader Packs screen and its option, the launcher's shader pack
browsing and installing, and the docs about them. Shader packs may come
back later as a clean-room rewrite.
The vanilla renderer and its post-processing (resolution scale, FXAA) are
unchanged. Options files that name a pack load and drop the key; the
launcher reads manifests that list a shader pack, and files in
`shaderpacks/` are never deleted.

Every release is now published as the release (one channel, Ludovic's
decision of 2026-10-23), so the launcher drops its Stable/Alpha choice:
the Updates row in Settings, `horizon-launcher update-channel` and its MCP
tool, the channel on the Versions page, in `versions` and in the footer.
It updates to the newest game release that is not a pre-release (GitHub's
latest) and looks every 30 minutes. The pre-releases of the old Alpha
channel stay listed and installable by hand, never as an update. Old
`update_channel` / `beta_builds` keys in settings.json are ignored.
On Linux a release build that starts no longer rewrites the
applications-menu entry to point at itself. It writes the entry only when
there is none, or when the program it starts (TryExec, else Exec) no longer
exists; turning the Settings switch on or `desktop-entry` still points it
at this launcher, and HORIZON_LAUNCHER_DESKTOP_EXEC is still honored. A
test build started with the real HOME took over a working entry and then
left it broken when its target/ was deleted (2026-10-23).

website/docs/agents.md, in the nav under "Going further", is the player's page.
It covers what an agent can do, connecting it from the launcher, copy-paste
config for Claude Code, Codex, Cursor and any MCP client, the game's AI Agent
page, a CLI quick reference, safety and No AI.
docs/agent-control.md is rewritten for developers:
- the surfaces, and why one MCP server covers the launcher and the game;
- the inventory, before and after, for the launcher and the game;
- No AI on every surface, and the launcher commands that stay;
- connecting from the launcher and the game;
- the design rules for a new command.
docs/launcher-commands.md lists every launcher command, its arguments and its
MCP tool. It is generated from the clap definition (cli_tools::markdown). The
launcher test the_launcher_reference_is_up_to_date fails when it is stale or a
tool is undocumented, like horizon-ctl's generated reference.

Drop the Horizon menu style (options_horizon.rs, front.rs, the live title
backdrop and its post grade, the launcher's menu-style setting, CLI and MCP
tool). Every screen is vanilla's. Horizon's own settings hang off vanilla's
Options the way mods add theirs: Horizon Settings... and Mods... take the
Telemetry/Credits slots, and Horizon Settings opens Graphics, Advanced
Graphics, Shader Packs, Controller Settings, Extras and Mods, each a vanilla
options list with tooltips. Play with friends moves behind vanilla's Friends
buttons: the pause menu's opens Play with Friends (share, copy, stop), the
title screen's opens Join a Friend, and Direct Connection takes a full code.
Old files load as before: horizon.txt's menuStyle line and
horizon-graphics.txt's level line are ignored.

The middle button (keyPickItem) over an inventory or the creative screen no
longer clicks like the left button: with infinite materials it clones the
hovered stack at full size (CLONE) or, holding a stack, drags full stacks into
slots (quick craft type 2); otherwise it does nothing. Agents can middle-click
widgets (click ID middle), and creative slots are ui widgets now.

`wait` ended with release_agent_keys like every other task, so
`key w down` + `wait 40` + `wait 20` walked for the first wait only.
A wait holds nothing: it leaves keys and buttons alone. They stay held
until `key ... up`, `release` or `stop`. Documented in horizon-ctl's
key/wait help (and so the MCP tools) and docs/agent-control.md.
Fixes#469

Two Horizon games under horizon-ctl, each with its own scratch home: the
host opens a survival world to LAN with commands, the guest joins by
address, and each check (tab, self, armour, nametags, chest, crafting,
damage) is reported on its own with screenshots of both sides.

The design sections now describe the implementation: ids for rows,
switches and segments, the redraw wait, wait-for --since and event KIND,
the events log (subscribe comes next), the launcher proxying through
horizon-ctl mcp. A before/after table and the PRs of each step replace
the plan.

What the launcher, the game socket, horizon-ctl and the two MCP servers
can do today, and one model for what comes next: shared names and JSON
shapes, a widget tree with actions by id, options get/set, waits, an
event stream, the launcher's MCP proxying the game, errors with a kind,
and the safety rules.
