A new harness decorates a 13x13-chunk area around each site, on both sides,
in the order vanilla's chunk scheduler uses around a player standing there
(chunk_dump HORIZON_LIST_ORDER prints decoration_order::vanilla_order), and
compares every block state, quart biome, block entity and scheduled tick:
the two reported spots on seed 1891623539983467248 (taiga trees at
204 -239; a stronghold with sculk and a geode at 4870 401), eleven tree-heavy
biomes and the nearest mineshaft, village, ancient city and trial chambers of
two seeds. 21 sites, 3,549 chunks, 0 differences.

The creative-tabs.json export failed to build the functional blocks tab (no
data-pack registries: banner patterns), and its fallback read decompiled
sources from a path that no longer exists, so the tab was empty and anvils,
crafting and smithing tables were missing from the tabs and the search. The
search also matched only an approximate display name.
VanillaCreativeTabsExporter now builds every tab with vanilla's own
CreativeModeTabs.tryRebuildTabContents over the vanilla data pack's
registries and writes creative-inventory.json: stacks with components, and
the search tab's creative tooltip lines and tags. The client searches them
as SessionSearchTrees does (FullTextSearchTree, IdSearchTree after '#').
Changing tab empties the search box, as in selectTab.
The scrollbar only jumped to the pressed point; holding it now scrolls as
the mouse moves, anywhere, until release (mouseClicked/mouseDragged), and
the wheel and the scroller follow ItemPickerMenu.
tools/test_creative_parity.py compares every tab and 6,793 searches with
the vanilla client's own search trees. horizon-ctl `type` also fills the
creative search box.

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.

Villager POI search: main's per-search state classification replaces this
branch's state table (same sections skipped, same positions in order).
status keeps main's mob and block-entity counts and this branch's pending
uploads.

The Horizon options shell's Video section now holds the graphics settings:
a Simple / Advanced switch (remembered in horizon-graphics.txt), then the
level's rows, each with its frame-time cost and one-line description
(ui_theme::described_row). Horizon settings draw as switches, sliders or
value buttons like vanilla options. The Classic style keeps the Video
Settings buttons to the same screens. Main's menu blur and the world's
resolution-scale pass are separate (post.wgsl, world_post.wgsl).

At render distance 32 the single section arena grew past the 4 GiB buffer
limit and the renderer panicked. Sections now live in pages of at most
256 MiB (or the device's buffer limit); draws keep their order and bind each
page once per run of consecutive draws in it, so translucent sections stay
back to front. docs/graphics.md describes the settings, the benchmark and
what changed; graphics_bench.py --compare prints a before/after table and
keeps each game's log.

Video Settings opens two Horizon screens (graphics_ui): Simple has the
Performance / Balanced / Quality / Ultra presets with render distance, FOV,
max framerate, VSync and GUI scale; Advanced groups every knob under
Rendering, Quality, Display, Performance and Overlay. Each row shows a
one-line description and its frame-time cost, and applies live. Layout lives
in graphics_ui, every colour, size and widget call in graphics_style, so a
menu theme can restyle them in one place.
Horizon-only knobs (horizon-graphics.txt, never options.txt): preset, cave
culling, chunk updates and upload budget per frame (nearest sections first),
sky, fog, weather, animated textures, present mode, frame pacing, worker
threads and the performance overlay (FPS, frame/CPU/GPU times and a
frame-time graph). Defaults keep vanilla's rendering; vanilla options keep
their options.txt keys.

Options open as the launcher's Settings page: a sidebar with the sliding
selection (Video, Audio, Controls, Accessibility, Language, Chat, Interface)
and rows with a switch, slider or value button per option
(options_horizon.rs; new sections or rows slot into SECTIONS). Key binds,
the language list and resource packs open vanilla's pages. Interface holds
Menu style (Horizon / Classic). The pause menu hides the in-game HUD over the
blurred world. Scripted and frame-limited runs default to Classic, so the
harnesses see vanilla's screens.

GameRenderer.render3dHud sets up the hand's projection at Camera's hudFov
(70, changed only by death and fluids), never the FOV option or the
sprint, speed and bow modifier. The hand pass now has its own globals
with that projection (a port of JOML setPerspective, as Projection does).
The camera harness compares the world and hand projection matrices at FOV
options 30, 70, 110 and others with vanilla's.

PipeWire remembers mute per application name. A test run's stream, muted once
in the mixer, left "PipeWire ALSA [horizon-client]" muted for every later game,
the release played from the launcher included: no sound at all, with the device,
the stream and the mixer all working.
- The launcher starts the game as "Horizon" (media.role Game), its own entry.
- The game opens no output on a vscreen, where agents run it (HORIZON_AUDIO=1
forces it, for a null sink), so nobody needs to mute it again.
- Any device sample format is accepted (the mixer converts from f32): a plain
ALSA default reporting i16 used to fail.
- Other output devices are tried when the default does not open, and the log
names the output opened or every reason none did.

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.

The Mac mini no longer excludes options, chunk_generation,
world_border_render and mob_ai: their float maths now matches vanilla's
on Apple silicon.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The Mac mini and ThinkPad no longer keep the shared vanilla data, so the
other machines are opt-in again.

Keep the integration branch's StringSplitter port and HUD overlays: the tab
list now emits hud_layout::GuiDraw calls and wraps with its split_lines, and
the vignette's border warning comes from WorldBorder::warning_strength
through hud_overlays::border_warning.

A sample of 27 harnesses (the 20 quickest, options, datafix's six shards)
passed there; it builds against the same ALSA headers as the desktop.

An original logo (a sun setting behind a blocky horizon), a banner and a social
preview card, and six screenshots captured in the Rust client. The README opens
with badges, a short pitch and a gallery; a test keeps the parity badge in step
with the subsystem table. Packaged builds use the logo as their menu icon.

Restructure the README around what Horizon is, its status, how to build it
from your own copy of the game, and its parity table. The Java performance
pack material and the research lab notes move to docs/java-packs.md and
docs/research-lab.md. The target platform is stated generically instead of
naming a machine, the stale list of missing mobs is dropped in favour of the
audited table, and the legal notice follows Mojang's usage wording.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Horizon no longer fetches anything of Minecraft from Mojang's servers. The
client jar, version JSON, libraries and assets come from the user's official
launcher install, and the server jar is one they downloaded themselves
(--server-jar or HORIZON_SERVER_JAR). Every file is checked against checksums
pinned in research-lock.json, and the prepared .local/ layout is byte-identical
to the old downloads, so the harnesses and the native client are unchanged.
CI keeps the offline checks on GitHub's runners; the vanilla comparisons and
the mod build need the game, so they move to a manual job on a self-hosted
runner that holds the maintainer's own copy.

A pass is keyed by the content of the harness's dependencies, so it is
also valid in any worktree with the same files. Passes are published to
parity-shared/ beside the shared vanilla data, and a worktree adopts one
whose key matches its own files instead of running the harness: an
agent's gate only runs what its own changes affect, instead of the whole
suite from scratch. Every runner on the machine also shares
PARITY_MACHINE_JOBS slots, so several agents' gates can't overload it.

Opening a world saved by an older version runs the file fixes, level.dat and
the DataFixers upgrades of every file instead of refusing it. The save
round-trip harness treats a lit campfire's cooking progress as a timer in the
vanilla views: Horizon saves it as loaded (stage 3 checks it exactly), and it
moves on by however many ticks each vanilla server ran before data get.
