Compile and validate original exporter bundles during release builds, cache development compilation, and reuse initialized JVMs and collision data during preparation. Keep legacy preparers compatible while current releases need only a Java runtime.

One source of truth for what is being done, what comes next and where to help: roadmap/roadmap.toml,
each item said twice (plain words for players, the technical picture for contributors), Now / Next /
Later / Help wanted / Shipped, no dates. tools/roadmap.py builds ROADMAP.md from it, checks its rules
offline (CI, through tests/test_roadmap.py) and against GitHub (links resolve, no stale Now item),
ships items whose pull requests all went out in a release (sync), and keeps a roadmap:<id> label per
item (labels). README links it; roadmap/README.md is the maintenance guide.

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.

Captured on the Mac mini with the game's offscreen capture (1280x720),
replacing the Horizon menu style's Video page.

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.

One-paragraph pitch, download and install, what works today with links to the
site's documentation, hosting and modpacks in two lines each, then build from
source, contributing and the project status table (moved lower, unchanged in
form so the site and tests/test_parity.py still read it). The stale release
notes section and launcher version are gone: the release notes are linked.

tools/server.py and docs/server-quickstart.txt are gone (horizon-server replaces them);
build_release.py builds only the client starter, and the docs point to docs/hosting.md.

Six scenes from one fixed-seed world (seed 8675309): a plains village among
savanna hills, sunset over it and the river, moonrise over its lit square, a
crimson forest with a zombified piglin, tropical fish over a warm-ocean coral
reef, and survival at dusk with a zombie and the full HUD. Plus Horizon's own
title, Singleplayer, Video options and pause screens.
Captured with horizon-ctl screenshot from the offscreen client (fullscreen
2560x1286 on the Mac mini, default graphics settings, GUI scale Auto), scenes
cropped to 16:9 and menus to 16:10 (left-aligned) and scaled to the old sizes
(1600x900, 1280x800). The scene sources are JPEGs in docs/media again, the
names scripts/assets.mjs already reads; the README's WebP copies are the
rebuilt website media. Alt texts and LEGAL.md follow the new pictures.
The launcher screenshots are unchanged: the Mac mini's session is locked, so
no window capture works.

pr_ready is the one self-check to run before asking for review: from the
files a branch changes it runs rustfmt, clippy with warnings denied, the
tests of the touched crates (mapped through cargo metadata), the launcher's
own workspace when it is affected, the tokens.css check, the Cargo.lock
rule, the Python tests and the public-tree check, and the vanilla harnesses
the change can affect, picked by tools/parity.py exactly as CI's parity job
picks them. It runs locally or on a fleet machine through ~/fleet/rbuild;
on the Mac mini the harnesses use the parity runner's own workspace and
scripts. It prints one Markdown block for the pull request body and exits
non-zero on any failure.
tools/parity.py gains --changed-files for copies without Git history, and
tools/ci/vanilla-data.sh accepts the preparation key from outside.

The README banner is redrawn in the new design (docs/media/banner.html), and the launcher and
menu screenshots (README and website) are the restyled ones. The website's launcher section
gains a Launcher tab: its screenshots no longer show the old background, whose licence was
never confirmed.

Vanilla 26.3 has no gamepad input, so this is Horizon's own, on Bedrock's
default layout (docs/controllers.md). gilrs reads the pads; the pure part
(bindings, radial deadzones, the look curve, button edges, the
horizon-controller.txt settings file) is in gamepad.rs with unit tests.
Buttons act as the vanilla key mapping they're bound to, through the same
path a rebound keyboard key takes (the keyboard's post-rebinding handling
moves into Game::mapped_key). The left stick is an analog move vector,
the right stick turns the view per frame, LB/RB step the hotbar, B and
Start leave screens and A respawns. horizon-ctl pad injects a virtual pad.

tools/fetch_sounds.py (and the lab.py functions it used) becomes
`horizon-prepare sounds` (horizon_prepare::sounds): the pinned asset index,
sounds.json and every .ogg from the player's own launcher install, each SHA-1
checked, into .local/horizon-client/<version>. The launcher runs it as part of
Prepare (in-process, the version's own binary when its sources differ and it
knows the subcommand, in-process for older versions), and a launcher install
without the assets only logs that the game will be silent. Player docs no
longer mention Python for sound.

The launcher prepares a version in-process when it ships the preparer sources
the launcher was built with, with the version's own horizon-prepare when they
differ, and with the Python script only for versions made before it. Release
folders ship horizon-prepare and its sources; resources are reused between
versions with the same preparer. The game's messages, PLAY.txt, the docs and
release builds name horizon-prepare, and tools/prepare_native_client.py is a
wrapper of it for the development tools.

The README keeps the parity table, and its known differences move to a
Known issues section. The website drops the What's next section and its
nav links, and no longer fetches or requires a Roadmap section. The
launcher drops its What's next page, `next` subcommand and `roadmap`
MCP tool.

README gets an Agent control section (out of the roadmap: it's done), the
native client guide describes every command group, the blocking semantics,
exit codes, launch discovery, MCP and the two transports, and PLAY.txt tells
release players about horizon-ctl.

- A banner in the website's design (Instrument Serif wordmark over a dimmed
sunset, purple accent), rendered from docs/media/banner.html with Playwright.
- Screenshots of Horizon's own menus and graphics settings, the in-game scenes
as WebP (from the website's media), and the launcher 0.1.3 Play and Patch
notes pages; the JPEGs the README no longer uses are removed.
- A "What changed" section matching the v2026.10.13.1 release notes.
- Download only through the launcher (playhorizon.dev or launcher-v releases).
- Roadmap: performance optimisation, mod support and agent control.

links.json gains a website key; the launcher shows a quiet Website link under
Join Discord and lists it in the links CLI command and MCP tool.

Removed (each unreferenced by code, workflows, tests or living docs; no harness
dependency record names any of them, and parity.py --list still finds all 281):
- 22 one-off write-ups of the Java-pack experiments in docs/: adaptive-terrain,
client-graphics-smoke, compact-headers, core-performance, culling-empty,
culling-rays, debounce-queue, dispatch-retry, foreground-first,
graphics-api-comparison, heap-budget, mac-first-test, optimization-plan,
playable-validation, quad-reuse, server-graphics-context, shader-world-smoke,
terrain-measurements, terrain-position, terrain-read-wait, tick-membership,
worker-pacing. Their findings are folded into one paragraph of java-packs.md.
- 24 benchmarks/ observation dumps only those write-ups linked (client graphics,
culling, queues, heap, Mac Vulkan, shader worlds, software identity, and the
unlinked rust-core, rust-worldgen-2026-10-05, rust-native-client and
rust-cuboid-model-decoding runs), plus 12 unlinked files inside kept
report folders. The scoped-parity reports the living docs cite stay.
- debug/: one server log from a chunk investigation.
- The manual macos-shader-research and macos-vulkan-research workflows.
- tools/logs/latest.log, an empty log committed by accident (now ignored).
Kept: research-lock.json (parity.py, packaging, the launcher and datafix read
it), the Java-pack how-tos (vulkan, collectors, profiling, process-memory,
tick-state) and tools/test_client_graphics.py (ci.yml runs it).
README: leads with what Horizon is and "Download the launcher" (the
launcher-v* releases; the launcher updates itself), then build from source
for developers. Direct game downloads and PLAY.txt steps for players are gone;
the launcher has its own section with two screenshots. The roadmap merges the
known differences, the final checks and the plans after parity, under the
"Roadmap" heading the launcher's What's next page reads. The parity table and
its 100%-of-what-the-harnesses-compare note are unchanged.
docs/README.md indexes what remains: build and run, parity (status and
workflow), world generation, world data and simulation, the old Java track.
Links to the removed pages and README anchors are fixed.
packaging/PLAY.txt now speaks to players who came through the launcher and
points anyone with a bare archive to it, keeping the manual steps short.
The launcher's README link points at main instead of the launcher branch.
.gitignore: tools/logs/ and .DS_Store. No code behaviour changes; the compiler
and clippy flag no unused code and the tree has no stale TODOs.

horizon_client::packs::SelectionModel ports PackRepository's selection and
PackSelectionModel (default positions, fixed and required packs, moving up
and down, commit), and the pack screen uses it. The new pack_selection
harness drives vanilla's model and Horizon's through 4,000 random action
sequences; every state matches.

Streaming kept, decorated and generated chunks within circles a fixed
margin wider than the render distance, but finishing a chunk needs its
3x3 neighbours decorated and theirs generated: squares whose corners
fall outside those circles. At render distance 2 the corner chunks around
the player never finished, so their neighbours never lit and the player
was never placed. Each step now also keeps what a finished chunk's
neighbourhood needs.

The Mac mini and ThinkPad no longer keep the shared vanilla data, so the
other machines are opt-in again.
