🤖 Agent: merged by Ludovic's AI agent once verify passed (the earlier failure was a flaky client test #721 doesn't touch; main passes it). Launcher tests run locally on main + #719 + #721: all pass. Thanks @rdbtCVS!
🤖 Agent: merged by Ludovic's AI agent. CI doesn't build the launcher on PRs, so launcher tests were run locally on main + #719 + #721 (cargo test --locked, macOS): all pass. Thanks @rdbtCVS!
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.

🤖 Agent: merged by Ludovic's AI agent. CI parity passed on the head; combined with current main (and #680) locally: workspace clippy clean, horizon-client 826 + horizon-world tests pass, mob_ai/save_roundtrip/spawner PASS. Thanks @Online5277!
A Prism or MultiMC instance keeps no jar of its own: the client sits in the
launcher root's shared libraries, two or three folders above `instances/`,
and the game is downloaded only once the instance is launched. Choosing
`%APPDATA%\PrismLauncher\instances` (or an instance's `minecraft`/`.minecraft`
folder) as the Minecraft folder failed Prepare when the jar was not there yet,
and the error only listed every launcher without saying what to do.
resolve now also looks in the launcher root above an `instances` folder, so a
folder deeper than the four walked above the chosen one still finds the
libraries. When nothing is found and the chosen folder is inside a launcher
Horizon knows, the error names it and says to launch the instance once so it
downloads the game.

🤖 Agent: merged by Ludovic's AI agent after local checks on a6592eb1: workspace clippy clean; horizon-client/world/protocol tests pass; lan, chunk_stage, dedicated_server, block_entity_storage, chunk_generation PASS.
Settings gains a one-line Game arguments field, kept as `game_args` in
settings.json and appended to the client's command line after the
launcher's own, so a player can pass things like `--server-thread` or
`--render-distance 40`. Quotes group a word with spaces in it.
`horizon-launcher game-args [<line>]` shows or sets the line,
`play --arg <ARG>` passes one for a single run, and the MCP launch_client
tool takes an args array. The same splitter feeds all three.
Closes#716.

TickCtx gained `collision` here; main's two newer initializers
(lan_actions respawn, server_travel's server_ctx) now pass it too, as
every other one does.

The LAN chunk encoder's section cache (#623) and dimension range (#668)
are kept; a cached section's wire bytes use the registry's palette width,
set once per process before any encoder exists, so the cache stays keyed
on the section alone. The sculk scan's palette check takes the u32 state.

LAUNCHER_PATHS and launcher.yml's push paths now list horizon-bench,
horizon-friends, horizon-mods and horizon-port-pack too, the launcher's
path packages per cargo metadata. A change there (like the horizon-mods
dependency that left launcher/Cargo.lock stale) then builds and releases
the launcher instead of going unnoticed.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
horizon-port-pack now depends on horizon-mods (1f1d5a5a), which the
launcher's own lock file didn't have, so every --locked build of the launcher
failed.

On Windows the launcher links another launcher's client jar with a hard link
(a copy across volumes) and its libraries and assets with a junction, since
symlinks need developer mode. canonicalize() of a hard link is its own path,
so the sources tests, which compared canonical paths, failed on Windows and
blocked every launcher release since launcher-v0.4.0. They now check that the
linked jar is the launcher's file (a byte written through one shows in the
other), which holds for a symlink and a hard link alike.
The modpack profile test compares paths as paths rather than strings ending
in "a/carry".
mklink /J's paths are always quoted: Rust only quotes arguments with spaces,
and cmd reads an unquoted & or ^ in a user folder as its own syntax.
CI runs every launcher test target, not just the library's.

The first criterion trigger of a world's first tick loaded the
advancement tree: about 1,400 JSON files read and parsed on the game
thread, about 60 ms of a 125 ms first tick. open_world now starts that
read on a thread, and the first advancement_tree() takes its result,
the same tree as before.

The hub tests every player's sent-chunk set for every entity and every
column of the view each tick, and each player's tracked-entity map for
every entity: tens of thousands of SipHash lookups a tick with 50
players. Both now use the Fx hash. Their iteration order was random
before and carries no meaning.

Every chunk packet scanned all 4,096 blocks of each section holding a
block entity block to list them, though the section's wire bytes were
already cached. The cache now keeps those blocks (index and state, in
scan order) beside the bytes, made in the same pass that encodes them.

encode_in asks whether each of the nine surrounding columns' 24 sections
holds anything, to decide which light layers exist: 216 cache lookups,
each locking the cache and SipHashing a section's address. The column's
sections now share one lock, and the cache uses the Fx hash.

The hub looked up an entity's tracking range (a binary search over type
names) for every player and every entity each tick: about 87,000 string
comparisons a tick with 50 players. The ranges are now worked out once
per entity per tick; the visibility test is the same.

The generation scan walked every area's square of columns, so with 50
players standing near each other it tested about 100,000 columns a tick
(each against every player's range) to find the few hundred around them.
The squares are now merged into one run per row first. The candidates
are the same: they were sorted and deduplicated before.
