LivingEntity.getDamageAfterMagicAbsorb applies Resistance, returns 0 when
nothing is left, returns the damage as is for #bypasses_enchantments (the
warden's sonic_boom), and only then the enchantment protection. Horizon's
Mob::hurt_server ran the protection first and never read the tag, so a
zombie in a Protection IV chestplate kept 1.6 of a 10-point sonic boom.
DamageKind::bypasses_enchantments (SonicBoom, or a NamedDamage with the
new BYPASSES_ENCHANTMENTS tag) gates the protection, which now follows
Resistance as vanilla orders them.

`ServerExplosion.hurtEntities` damages every entity in reach, and
`ItemEntity.hurtServer` writes the result back:
this.health = (int)((float)this.health - amount);
if (this.health <= 0) { this.getItem().onDestroyed(this); this.discard(); }
Horizon's item branch only asked whether the damage reached 5 and destroyed the
item, so an item that lived through a blast kept all 5 points of health: a
power-5 bed blast that leaves vanilla's item at 1 left Horizon's at 5.
The damage is now subtracted in f32 and truncated after the subtraction, as the
cast does, and the item is destroyed at zero health as before. The nether star
stays immune through `ItemStack.canBeHurtBy`'s explosion exception, and a blast
whose source is an entity with `mobGriefing` off never reaches the branch
(`items_ignore`).
A dropped item starts with 5 health and `ItemEntity.hurtServer` takes the
blast's damage off it, so a survivor's `Health` says how much of the blast it
took. The pinned compound the ring already reads carries it, so the compared
line grows one fact:
data push -0.03 -0.00 -0.05 health 1 keep 0.9800
Red on main: Horizon reports `health 5` where vanilla reports `1`.
BoneMealItem.addGrowthParticles places a NEIGHBOR_SPREADER's happy
villager sparks at BonemealableBlock.getParticlePos, which is the block
above for grass, nylium, netherrack and moss; a GROWER keeps the block
itself, rooted dirt and mangrove leaves the one below. Horizon used the
bone-mealed block for spreaders too, a block lower than vanilla.

Player.actuallyHurt awards DAMAGE_TAKEN as Math.round(dmg * 10.0F) only

nothing. A damage_taken_award helper applies the threshold and
jmath::round_f32 (Math.round(float): ties up, saturating).

Creeper.readAdditionalSaveData reads ExplosionRadius as a byte (default
3), addAdditionalSaveData writes it back, and explodeCreeper blows with
it, twice it when powered. Horizon used a fixed 3 or 6 and never read the
key, so a summoned creeper with ExplosionRadius:12b blew with 3.
Extra.explosion_radius holds it (3 from Mob::new), entity_nbt reads any
numeric tag narrowed to a byte and writes the byte, and creeper_tick
scales it by the powered multiplier.

The survivor the harness gained at the edge of the blast is read through the
item's own tick counter. A push on an item decays every tick
(`Entity.getAirDrag`, 0.98), and the two servers do not advance the same number
of game ticks between the same commands: at three script points of one case the
vanilla survivor was 31, 33 and 48 ticks old and Horizon's 38, 41 and 75, so a
`Motion` read there measures the pacing rather than the blast.
The edge item's `Age` is now read before the blast, and its whole NBT (`Age`,
`Pos` and `Motion` from one snapshot) at two pinned ages after it. The case
compares the push carried back over the ticks since the blast, to two decimals
because a tick of slack between the blast and the read is worth 2%, and the
decay the two snapshots show per tick, to four, which is `getAirDrag`'s 0.98.
Both agree with vanilla's in all twelve cases.
SnbtGrammar accepts one trailing comma before the closing brace or
bracket; a comma alone and two in a row stay errors. Both readers take it:
horizon-world's parse_snbt (NBT arguments, item components) and the text
component reader (tellraw and other component arguments).

Root cause: #9335 follow-ups from #8733 left passenger rotation after /tp covered only by parity corpora (tools/passenger_teleport_corpus.py), which cannot run without vanilla data. The Game-level rider test exercised offset carry (sub-item 1) but not the rider keeping its angle to the vehicle through absolute and relative turns (sub-item 2).
What changed: extend teleport_rider_tests::a_vehicle_carries_its_riders_and_a_rider_leaves_its_vehicle with a second horse/villager pair: absolute turn 0->40 leaves rider at 70 (30-degree offset kept), relative turn to 50 shifts rider 70->80, and facing (turn_riders=false) leaves rider at 80. No runtime change; the teleport/passenger writers already implement Entity.teleportSameDimension/calculatePassengerTransition via vehicle_teleport::passenger_rotation.
Vanilla reference: 26.3 Entity.calculatePassengerTransition, PositionMoveRotation.calculateAbsolute, Entity.setXRot (pitch clamp).

tools/test_enchanting_parity.py always built a fresh ItemStack for its offer
corpus, so EnchantmentMenu.slotsChanged's ItemStack.isEnchantable gate (the
enchantable component and an empty minecraft:enchantments) was never

damage and a pre-existing enchantments entry; the oracle applies the gate and
the probe builds the same stack. The default corpus is unchanged and
--no-components reproduces it.

Gui.setScreen runs KeyMapping.releaseAll for every screen and
Minecraft.tick skips handleKeybinds while one is up, books, the sign

those, and its release-all (track_toggle_screens) and the client input
gate (remote_handle_input) only knew the server dialog, while the book's
and sign's mouse arms eat both edges of a click: a dig held into a book
went on after the book closed, until the next click.
gameplay_has_keyboard now takes "a screen is over the world"

LocalPlayer.getRopeHoldPosition eases the lead's hand end from the view
to yRotO/xRotO by half the partial tick. Entity.turn moves yRotO and xRotO
by the mouse's delta too, and AbstractBoat.clampRotation moves yRotO with
the clamp, so only what the tick turned (a boat's deltaRotation) eases in.
Horizon's rope_rot_old was a once-a-tick snapshot the turn never moved:
while the mouse moved, the hand end lagged by half the turn since the
tick began and snapped back at the next tick, 20 times a second.
turn_player now moves rope_rot_old through the same Rotation::turn as the
view, and both boat clamps (the turn's and the tick's) move it with the
view. A test pins that a mouse turn leaves no gap, a boat turn eases, and
xRotO clamps at 90.

`HappyGhast.addAdditionalSaveData` writes `still_timeout`, the timer
`still_tick` keeps in `counter`; `readAdditionalSaveData` reads it back and
a save without it is 0.
0, 7 and 10 through `mob_to_nbt` and `mob_from_nbt`: the Int vanilla writes,
the timer back on the mob, and `on_still_timeout` following it. Without the
writer the saved tag has no `still_timeout` (the test fails on `left: None,
right: Some(0)`).
`HappyGhast.addAdditionalSaveData` writes `still_timeout`, the
`serverStillTimeout` behind `staysStill`/`isOnStillTimeout`, and
`readAdditionalSaveData` reads it back:
protected void addAdditionalSaveData(ValueOutput out) {
super.addAdditionalSaveData(out);
out.putInt("still_timeout", this.serverStillTimeout);
}
Horizon keeps that timer in `Mob.extra.counter` (`happy_ghast::still_tick`
counts it down after the first 60 ticks, `player_above` refreshes it to 10)
but neither `mob_to_nbt` nor `mob_from_nbt` touched it, so a ghast saved
while it was held still came back with 0. For the ticks vanilla restores, a
dropped item resting on its back had no box to rest on
(`EntityGetter.getEntityCollisions` takes a happy ghast only while
`isOnStillTimeout`), and a rider had no control (`getControllingPassenger`
asks `isOnStillTimeout`).
ByteBufCodecs.holder in vanilla 26.3 reads a VarInt and, when it isn't 0,
looks the entry up with `byIdOrThrow(id - 1)`, which no negative id passes.
skip.rs's `holder` accepted any nonzero id, so a slot whose kinetic_weapon
sound holder was negative was kept as a raw component, and hashing it for an
inventory click computed `id - 1` on i32::MIN: a panic with overflow checks
on, a wrapped id otherwise.
ByteBufCodecs.holderSet reads the size plus one and builds
`new ArrayList(size)`, which refuses a negative size. `holder_set` computed
`n - 1` before checking the sign, the same overflow for i32::MIN.
Both readers now refuse a negative value with a protocol error, so every
component that reads a holder or a holder set gets the same boundary.
Valid direct and registry holders read as before (their vanilla hashes in
hash/raw.rs's tests are unchanged).

Guard against negative scale values producing excessive shift

ServerGamePacketListenerImpl handles a client's packets in order: the
RELEASE_USE_ITEM a client sends from handleKeybinds comes before the move
LocalPlayer.tick sends in the same client tick, so the server shoots from
the position of the move it handled the tick before, one tick of strafe
behind the camera. Hub::process_inbox applies moves at once and hands a
PlayerAction to the game for after the pass; it held a queued move behind
a dig, UseItem, UseItemOn and Interact, not behind the release, the drops
or the stab. The move ran first, and the arrow left a tick ahead of the
camera: strafing left, it seemed to come from the left instead of the
right.
Every PlayerAction now holds the queued move for the next tick. A test
drains a release followed by a move and checks the game gets the release
alone with the guest's position and known movement unchanged.

Entity.removePassenger sets the leaving passenger's boardingCooldown to
60, but Player.removeVehicle overrides Entity.removeVehicle and zeroes it
right after super.removeVehicle(), so a player never waits to board again;
only mobs do. #8733 (from #8586, which missed that override) gave the host
and every guest the 60 ticks, checked by may_board before boarding a boat,
cart, cushion, ghast, llama, mount or nautilus: the delay the issue
reports.
The player's cooldown goes: the boarding_cooldown and riding_at_tick
fields of Game and Guest, their swap for a guest's turn, the per-tick
count-down and may_board at its eight call sites. Each interaction still
refuses a sneaking player, the other half of Entity.canRide. Mobs keep
extra.boarding_cooldown.

LivingEntity.addAdditionalSaveData writes FallFlying as isFallFlying(), and
readAdditionalSaveData sets shared flag 7 from it, so a player who saves
mid-glide resumes the glide on the next load. Horizon wrote a fixed
FallFlying of 0 and never read it back: the player came back standing in
mid-air.
Level now keeps fall_flying, read from any numeric FallFlying tag (as
getBooleanOr does) and written from the guest's glide; playerdata's store
and apply carry it between the Guest and the file. The server's next
sync_player_state sends the 0x80 shared flag to the client, and
updateFallFlying's port ends the glide if it can't go on.

Entity.shouldBeSaved is true for every projectile in 26.3, and
WitherSkull adds `dangerous` on top of the hurting projectile's

and a blue skull came back as nothing.
Write and read the skull the same way as the fireballs: `dangerous`

tools/test_block_removal_parity.py only ever mined as a survival player:
every mine case ran ServerPlayerGameMode.destroyBlock in SURVIVAL, so the

wear) was never compared even though game.rs::break_block_as_player splits
on it. Half the mine cases now run in creative, with a tool that can destroy
blocks in creative (a sword and a mace cannot, which the creative-mining
predicate corpus already owns).
VanillaDispenserOracle's Miner gains a creative flag (isCreative and

fixture sets the same mode for the case. --survival-only reproduces the

gbuffers_skybasic drew every part of the sky with the translucent blend.
Vanilla 26.3 draws the sky disc and the dark disc with RenderPipelines.SKY

the stars with RenderPipelines.STARS (BlendFunction.OVERLAY: colour
SRC_ALPHA ONE, alpha ONE ZERO). Iris 1.11.7 drew them so with probe packs

0.9, 0.25) in buffers of four formats, and the stars added 0.25 x 0.5 to
the disc's 1.0 and left their own alpha 0.5. Without a
blend.gbuffers_skybasic of the pack's own, the disc and the void, and

Thank you for adding Thai to the launcher in #8306. We were really
happy to see it. When we used it, though, many lines were hard to
understand for us as Thai players. The translation looks
machine-made, and many words have their everyday meaning instead of
their computer meaning. We rewrote it so that Thai players can use the
launcher comfortably. 731 of the 1225 strings changed. The others
were already good, so we kept them as they were.
Below is each word we changed, what it is now, and how a Thai reader
understands the old word. We hope this makes our reasons clear, even
if you don't read Thai:
- build: อาคาร / โครงสร้าง -> บิลด์
อาคาร means a building (a house, an office). โครงสร้าง means the
structure of something. "Native build" read as "the original
building". Thai developers and players say บิลด์, written as it
sounds.
- instance: ตัวอย่าง -> อินสแตนซ์
ตัวอย่าง means "example" or "sample", so "Instance" looked like a
demo copy of the game, not a separate game setup. อินสแตนซ์ is the
English word written in Thai, as Thai players say it.
- native (mod, build): ดั้งเดิม -> เนทีฟ
ดั้งเดิม means traditional or original. "Native mod" read as "the
original mod", which says nothing about compiled code. เนทีฟ is the
usual Thai programming word.
- launcher: ตัวเรียกใช้งาน / ตัวเปิด / (left in English) -> ลันเชอร์
The same thing had three names, so a player could not tell they
were one program. ลันเชอร์ is what Thai players call it.
- jar: ขวด / โหล -> ไฟล์ jar
ขวด is a bottle and โหล a glass jar for food. "Port gets the jars"
read as "Port gets the bottles". It is a file type, so ไฟล์ jar.
- Loader: รถตักดิน -> ตัวโหลด
รถตักดิน is a wheel loader, the construction vehicle.
- Client: ลูกค้า -> ไคลเอนต์
ลูกค้า is a shop customer. Here it means the game client.
- Running / run: วิ่ง -> กำลังทำงาน / รัน
วิ่ง is running on foot. "Running" read as "jogging". A program
that runs is ทำงาน (working) or รัน.
- Proxy: หนังสือมอบฉันทะ -> พร็อกซี
หนังสือมอบฉันทะ is a legal power-of-attorney letter.
- port: ท่าเรือ -> พอร์ต
ท่าเรือ is a harbour for ships. A network port is พอร์ต.
- cape: แหลม -> ผ้าคลุม
แหลม is a headland on a coast (or "sharp"). A Minecraft cape is a
cloak, ผ้าคลุม.
- cosmetics: เครื่องสำอาง -> คอสเมติก
เครื่องสำอาง is make-up (lipstick, powder). Thai gamers call
in-game items to wear คอสเมติก.
- seed: เมล็ดพันธุ์ -> seed
เมล็ดพันธุ์ is a plant seed for farming. Thai Minecraft players use
the English word for a world seed.
- Home (page): บ้าน -> หน้าแรก
บ้าน is a house. The Home page is the first page, หน้าแรก.
- Ban: บ้าน -> แบน
Ban was also translated as บ้าน ("house"), so the ban button said
"house". Thai players say แบน.
- founder (set): ผู้ก่อตั้ง -> ผู้เล่นรุ่นแรก
ผู้ก่อตั้ง is the person who founded a company, so "Free for
founders" read as "free for the people who started Horizon". The
shop page says the set is for "the players who were here first", so
it is ผู้เล่นรุ่นแรก, "early players". It is not "sponsors" either:
the set is free.
- player counts: คน -> ผู้เล่น
"{online} of {max} players" used คน (person). In a server list Thai
players expect ผู้เล่น (player), as the game itself says.
- Java Edition: รุ่นจาวา -> Java Edition
A product name, like Minecraft and Microsoft, which stay in
English. รุ่นจาวา ("the Java version") reads as a Java release.
- 78 strings still in English -> translated
They showed English in the middle of a Thai screen.
- Polite particle ครับ removed
ครับ is the spoken "sir" that ends a sentence when a man talks. In
UI text it sounds like a person talking, not a program.
We kept every {placeholder} and every middle dot of the English, and
we used one Thai word for each English term across the whole file.
The two of us, both native Thai speakers, read every changed line
(SamsVT and NotNiceKun). If anything still reads wrong,
please tell us and we will gladly fix it. Thank you for Horizon!

Horizon split a dying cube at the moment of death. Vanilla
AbstractCubeMob.remove runs the split when the entity is removed, which
LivingEntity.tickDeath does after the death animation (deathTime 20),
so the smaller variants appear about one second later.
The oracle's stand-in player overrode LivingEntity.startUsingItem and only recorded the item, so
the real vanilla vibration never ran: ItemStack.causeUseVibration posts ITEM_INTERACT_START when
the stack's use effects ask for interaction vibrations, which every item's UseEffects.DEFAULT
does (DataComponents.COMMON_ITEM_COMPONENTS). Since #10272 Horizon posts it, so the harness
reported 284 false mismatches (4916/5200). It now calls causeUseVibration under the same guard
as vanilla: 5200/5200.

Validation: native prepared-resource Game test verifies offhand wear, break event48, unchanged main-hand stack, legacy event47 and creative immunity. Strict gameplay clippy, formatting and public-tree checks pass.

🤖 Agent: foudretbr's rebase onto main (a1ff75a4a) drops the stray `);` that broke `tests/mod_api_hooks.rs`, and the file-wide import reorder. The hook change is the same 9 files: with no mod loaded, every translucent screen background is still the vanilla gradient. The 10 hook tests and tests.test_stamp_native_hooks pass.
🤖 Agent: merged main so this builds again (its old base still called `mob_to_nbt` without the UUID lookup that #10544 fixed). Burst notes are unchanged: one group per packet kind, each naming the player who spent the most time; the 7 burst and event-timing tests pass on the merged head.
Cache conservative envelopes of every baked model alternative, invalidating
on mutable model access. Reject rear-origin falling blocks only when their
complete padded model is outside the posed camera's depth clip planes.
Depth-only clipping preserves TAA jitter and screen-edge geometry; shader
packs keep their original path.
Include geometry/cache regression tests and separate ordinary/TAA FPS and
image comparisons, with front/empty controls and an oversized model fixture.

🤖 Agent: README/docs-media only; keeps the Project status block and '### Java parity' table the site and tests read, so playhorizon.dev's parity number is unaffected.
The README's pictures were from mid-October (launcher 0.2.30, the old
menus), so this retakes them and tidies the page around them.
- Pictures: Nightly 2026-11-05 (66f3981) windowed on the Mac mini's M4
Pro (Metal) with seed 8675309: a river valley with a village and a long
view, a cherry-grove sunset, a crimson forest with a piglin, survival
with the HUD, and two players over LAN; the launcher 0.2.47's Home (with
those screenshots in its instance) and Mods pages. WebP, 712 KB in all,
under docs/media/readme/. The five README-only images they replace are
removed; village/nether/underwater.webp stay (the launcher embeds them).
- Text: a short pitch, what works in the current release, a download
table with each platform's file and requirements (Windows x64 and Arm,
macOS Apple Silicon and Intel from 12, Linux glibc), the Microsoft
sign-in requirement, mods and shader packs (Java mods don't run;
modpacks import), hosting, agent control, build from source,
contributing, and Mojang's "NOT AN OFFICIAL MINECRAFT PRODUCT" line.
- Fixed claims: macOS Intel and Windows on Arm are out (not "from the next
Nightly"); the known-issues line points to docs/known-issues.md.
- Two badges instead of seven: the parity and gap badges the tests and
tools/parity_gaps.py keep in sync. "Project status", its gap block and
the "### Java parity: N%" table are unchanged, so the website still
reads its number and #build-from-source/#project-status still resolve.
Builds on #11040 by Web-mc1, who first noticed the launcher pictures were
outdated and retook them.

🤖 Agent: merged #10312 (with main) in. The cache compares the whole Scoreboard twice per frame (displayed_ids and layout) and clones it on every change, so a server ticking a sidebar score every tick rebuilds and clones each frame; still cheaper than the old double sort, and tab_list parity passes on a union holding this head.
🤖 Agent: merged main in: #10328 (merged meanwhile) now caches the layouts of the tags your collect_name_tags keeps, and #10098's new hide_gui argument is passed in your early tab_list::visible check too, so F1 still hides the list on the skip path. Skipping a tag whose entity box (inflated 0.5) is off the frustum matches vanilla, where shouldRender gates the name tag with the entity. 194 selected harnesses run on a union holding this head: tab_list and hud pass, the 8 failures are identical without it.

Prevent vertical letter-by-letter text stacking and control clipping

Upstream's UUID bridge (#10304) now writes a mob anger target's UUID
through mob_to_nbt's uuid_of. The branch keeps its two additions on top:
a target read from the save that is not in the world keeps the loaded
UUID, and the loaded angry_at goes once the anger is over.
A mob only gets its UUID when it is first saved, so an anger target
not saved yet came out with no angry_at (wolves too). mob_tree_nbt now
gives a target that is still in the world its UUID first; the new
anger_at_a_mob_not_saved_yet_names_it test failed without that.

The integrated server matched the used item by id (minecraft:totem_of_undying)
and used it up before the client looked for it, so any other item with
death_protection showed a plain totem in the activation animation.
Vanilla LivingEntity.checkTotemDeathProtection takes the first hand whose
stack has DataComponents.DEATH_PROTECTION, keeps a copy before shrink(1), and
uses that copy for the stat, the used_totem trigger and the animation.

ThrowableProjectile.tick runs on the client too: handleFirstTickBubbleColumn
before gravity, then applyEffectsFromBlocks' BubbleColumnBlock.entityInside
after the move, with Projectile's unclamped pushes (+0.06 inside, +0.1 at the
surface, -0.03 dragging down). The client's remote_projectile_tick had none of
it, so a pearl held in a stasis chamber on a server sank between the tracker's
updates and snapped back on each one.
Projectile::tick_remote adds both for ThrowableProjectiles, through a new
ProjectileWorld::bubble_column hook (bubble_column_at for the game's world).
The integrated and dedicated servers keep pushing their pearls in the
creature tick, so their projectiles are not pushed twice.

The shelf mushroom is a solid shelf players stand and bounce on (ShelfMushroomBlock's shape); the brown

be pulled back. Its block now shows as brown_mushroom_block, whose collision holds the shelf's; the item stays
brown_mushroom. The new explorer maps are filled maps (MapItem), so they show as filled_map, which draws their

🤖 Agent: the pre-tick hook swapped each guest's whole state into Game every tick even with no mod loaded; I pushed a guard so `as_guest` runs only when `mod_api::mods()` isn't empty. The fragment passes tests.test_stamp_native_hooks.
🤖 Agent: verify failed because bake_bricolage.py imports fontTools before it reads its arguments, and CI has no fontTools. I pushed a change that checks the arguments first, so the new usage test passes without fontTools installed.
🤖 Agent: #10398 asked that a local build in a folder with a space still builds, so I pushed a fallback for GNU windres when the volume has no 8.3 names: outside CI it warns and builds without the icon instead of failing. With the taskbar-icon commit, `cargo check --target x86_64-pc-windows-gnu` passes on the desktop for horizon-client and horizon-client-input.
🤖 Agent: a failed region already restores its originals, so blocking the server start on any prune error took a server down for one corrupt chunk record. I pushed a change that starts it when no journal is left, with a supervisor test for it. Note that delete mode now writes regions one at a time with fsync, so a large prune takes longer than the old parallel rewrite. 169 horizon-server tests pass on Linux.
🤖 Agent: raids.rs now passes the same `persist.uuid_of` lookup persist.rs gives `mob_to_nbt`, and the four entity_nbt.rs test calls get `|_| None`, so main builds again after #10304 (verify green on this head).
🤖 Agent: translations only; %s placeholders kept and every file parses. The languages you flagged as uncertain (ba_ru, cv_cu, sah_sah...) stay worth a native speaker's look.
🤖 Agent: removes the old pack pages, their two slider kinds and four lang keys in all 87 files; nothing else read option_label_within, checked with clippy -D warnings on the stack over current main.
🤖 Agent: The non-constant texel offset becomes offset / textureSize(level 0) added to the coordinate: right for the base level, but at a sampled lower mip the shift is in base-level texels, not that level's (GL moves by texels of the level read). Fine for Arc's FXAA at level 0; worth a note if a pack hits it with textureLodOffset.
🤖 Agent: CAT_* macros come from biomes::CATEGORIES, so they pick up #10499's CAT_MOUNTAIN 17 and CAT_UNDERGROUND 18 with no second table to keep in sync; your test comparing every macro with constants() covers that.
🤖 Agent: The constant evaluator now refuses a non-finite F32 fold with Overflow, and only GLSL function bodies turn that into a run-time expression, so WGSL input still rejects 1.0/0.0 at compile time. Vendored naga's own 133 lib tests pass with the chain.
🤖 Agent: The integer-sampler helpers texelFetch the texel under the point with the coordinate clamped to the edge, which is what GL's nearest read of an integer texture gives; a bias argument is accepted and ignored, as GL does for these. Stack 3/6, checked with the rest of the chain on current main (clippy -D warnings, horizon-shaders and render tests).
LivingEntity.playBlockFallSound: the block 0.2 below the feet, at half

Every frame each text display built a batch, emitted its styled glyphs and
transformed every vertex, and a display of width or height 0 (what plugins
summon for holograms) is noCulling, kept to the distance rule because its
transformation can put the text anywhere: 200 of them cost ~0.3 ms a frame
with none on screen (#4664).
Each display's local-space text quads are now kept, rebuilt when the text,
its style, opacity, background, shadow, see-through, the font epoch or the
GUI atlas revision change (obfuscated text every frame), and only
transformed per frame. A noCulling display is skipped when the box of its
quads, through this frame's full matrix, misses the frustum: it can't draw a
pixel. Displays with a size keep vanilla's box test; the view range stays.
#10398 asked that a local build in a folder with a space still builds: a
volume without 8.3 names gives windres no usable path, so outside CI
such a build warns and goes on without the icon, as before. CI and
every other case still fail without it.

On Peaceful, vanilla never lets a player be a mob's target
(`LivingEntity.canAttack` refuses a player there), so a mob that already
held one gives it up. A neutral mob also stops being angry and forgets
who hurt it (`NeutralMob.stopBeingAngry` calls `setLastHurtByMob(null)`).
Horizon dropped a player target only for creative and spectator players,
so an iron golem that had been angered kept attacking after the
difficulty was set to Peaceful.

Loading a shaders/ pack made its pipelines on the main thread, and the driver
compiles each program there: the game froze for 5 to 50 s on a big pack
(Complementary Reimagined, Photon), with no frame drawn.
The renderer now builds the pack on a "Shader pack" thread (load_shader_pack)
with its own handles to the device and the inputs, and the game keeps drawing
without a pack meanwhile; each frame poll_shader_pack checks the thread and
runs the pack once it is built, logging its programs and notes as before. A
pack the thread refuses or panics on is turned off as before. Picking another
pack, or none, drops one that is still building.
A boat's or minecart's box query (boat_contacts, boat_obstacles,
cart_entity_collisions) asked every mob of the level for its box, and
Mob::bounds reads the mob's whole size (dims: sleeping, baby, species, scale)
across several cache lines. While boats and carts tick, the widest half width
and tallest height of the mobs (BoxReach) are worked out once, and a mob whose
position is farther than that from the query is skipped without its box. The
reach is worked out again when a mob joins or leaves, and nothing a vehicle
does resizes a mob, so the same mobs are found.
What a Horizon server sends a 26.2 client (accept_older_clients) now carries 26.2's

now leave out components the client lacks. A creative slot or container click from the
client is read with its ids up.

🤖 Agent: is_prepared now answers from a 5 s per-version cache (21.4 µs to 0.21 µs per call); need_prepared and the CLI still run the full per-file check, so an empty JSON is caught before launch.
Only packet ids are translated for an older client so far (#10404): the
registry data, tags (registry ids) and play packets (chunks, light, login,
player_action numbering...) would reach a real 26.2 client in 26.3 ids and
layouts. With accept_older_clients on, such a client now logs in and is
told so in configuration, right after the known packs and before any of
them. NetConfig::older_clients_play (tests only, not in server.toml) keeps
the play path reachable for the id renumbering test until the later parts
translate the contents.

#10389 made is_prepared parse research-lock.json and the manifest, list the
prepared folder and stat every table on each call. Pages call it while drawing
(instance rows, the Play menu, can_start), so every frame did file I/O.
is_prepared now keeps its answer per version folder for 5 s and drops it when
the launcher installs, removes, reuses resources or a job exits.
check_prepared runs the full check and refreshes the answer; starting the game
or a server (need_prepared), the CLI and the post-prepare auto-play use it, so
an empty JSON is still caught before a launch.

🤖 Agent: Entity.checkFallDamage subtracts (float)ya into the double, which the f64::from(.. as f32) step reproduces, and Entity.load reads fall_distance back. Main merged in again after #10422 landed (GitHub read the criss-cross bases as a conflict); the diff to main is this PR's own 6 files.
🤖 Agent: `camera_list` is now collected into a Vec on every frame, even with no pack, where the old iterator was lazy; it's one small allocation per frame. The shadow-only set and the spawner's `shadow_pass_drew` scan (linear in shadow_visible per spawner) run only under a pack whose shadow draws entities.
`biome_category` read 0 (CAT_NONE) in lush caves and the other cave biomes,
where Iris 1.11.7 reads 5 (CAT_PLAINS), and differed in 12 more vanilla
biomes. A probe pack of ours read Iris's value in each of vanilla 26.3's 67
biomes (`fillbiome` around the camera): they fit vanilla's `is_*` biome tags
(BiomeTags; `is_savanna` unused), then desert, swamps, mushroom fields and
snowy plains by name, NONE for the void, and PLAINS for the rest. Mountain
biomes read 17, which Iris names CAT_MOUNTAIN; CAT_UNDERGROUND is 18.
Biomes vanilla doesn't have keep the old guess from words of their name.

A pack (or the dimension folder it uses) with no gbuffers program for terrain
had the game draw terrain itself, into colortex0 and depth. Iris 1.11.7 draws
none: with probe packs of ours having no gbuffers programs, at the root or in
world-1 below a root that has them, colortex0 held only the sky (or fog
colour), entities and particles, depthtex0 had no terrain, and colortex1 to 7
none either; water and lava were missing too.
When no program of gbuffers_terrain's chain (nor _solid or _cutout) is in the
folder, the pack takes solid and cutout terrain from the game and draws
nothing; the same for translucent terrain and gbuffers_water's chain. A
program that is there but fails to load still leaves terrain to the game.

🤖 Agent: Mob.addAdditionalSaveData always writes canPickUpLoot(), so moving it out of the put-if-absent defaults is the fix (Allay and sulfur cube overrides now win over a loaded byte). Main merged in after #10393 landed; clippy and the entity_nbt tests pass on the merge.
🤖 Agent: piglin_replace follows Piglin.canReplaceCurrentItem in order (PREVENT_ARMOR_CHANGE first, then wanted/unwanted, then Mob.canReplaceCurrentItem), with getPreferredWeaponType null for babies.
🤖 Agent: `is_prepared` now reads the manifest and stats every top-level JSON on each call, and the launcher calls it from render paths (glass_home, glass_palette, can_start): a few hundred µs per frame at most, but a cache keyed on the folder would remove it. I dropped the unused `is_json_file`; launcher clippy and backend tests pass.
🤖 Agent: checked on Linux with mingw: the build script now compiles `main_res.o` for x86_64-pc-windows-gnu and passes it to the link, which the host-gated `#[cfg(windows)]` skipped. I kept the warn-only fallback outside CI for windres paths with a space (#10398).
🤖 Agent: causeExtraKnockback's non-living branch is Entity.push (no knockback resistance, no halving), as strike_boat does; the guest path still checks the attack range before skipping look_at_entity. We merged #10434 into this branch: both extend the boat fixture and harness.
🤖 Agent: for one-digit mantissas {:.1e} picks the closest two-digit decimal, which is what Java's Float/Double.toString does (Float.MIN_VALUE prints 1.4E-45). We switched the harness to the shared release world_probe: debug at CARGO_BUILD_JOBS=1 would have compiled horizon-world again in CI.
🤖 Agent: RealmsPdpScreen shows the trial description (and a Try for free button) only when trialAvailable; Horizon does not ask for it, so we dropped the description and kept the title with Buy, vanilla's no-trial layout. Titles are drawn plain where vanilla underlines/bolds them: small follow-up.
🤖 Agent: start() matches NeutralMob.stopBeingAngry plus IronGolem.startPersistentAngerTimer (nextInt(381) + 400 = rangeOfSeconds(20, 39)) at target priority 4. We moved the creeper test's doc comment back onto its own test: the new test had been inserted between them.
🤖 Agent: the tier fetch and both PUTs hit the same paths as RealmsClient.getRealmTierConfiguration/updateRenderDistance/updateSimulationDistance, and a reply missing either range is an error as in vanilla; nothing beyond what the vanilla settings tab offers.
🤖 Agent: only Tags move to the new id, as ConversionType.convertCommon copies them; the old raw compound (UUID, species data) is left behind, which the save/reload test checks.
🤖 Agent: hook_block_hit now runs on the client before moving, as FishingHook.checkCollision does on both sides, and gravity is f64::from(0.03f32) (getDefaultGravity is a float).
🤖 Agent: matches Pig/Strider.getControllingPassenger (saddled, first passenger a player holding the right stick in either hand); the server side reads the same rule through moved_by_client, so it no longer simulates the mount twice.
🤖 Agent: component_bool matches NbtOps.getBooleanValue (doubleValue != 0, so 0.5f and NaN are true, Short 256 too), not NumericTag.asBoolean's byteValue; that is the Hypixel glint_override report.
🤖 Agent: LivingEntity.aiStep resets fall distance for slow_falling or levitation before travel, NoAI included; dropping the later travelInAir-style reset is right, it erased the current tick's descent.
🤖 Agent: packet_utf8 differs from from_utf8_lossy only on ED A0..BF (encoded surrogates), which Java consumes as one replacement; the length limits still use the encoded bytes first and UTF-16 units after, as Utf8String.read does.
🤖 Agent: reading the bytes once and parsing them removes the exists()-then-load race too; only NotFound starts an empty list, so a directory or a locked ops.json now stops the stopped-server command instead of being overwritten.
🤖 Agent: fangs_allied follows Entity.isAlliedTo both ways (AbstractIllager tag only when both are teamless, Evoker's vex root-owner rule); guests on the evoker's team are still bitten, as before, which is a follow-up rather than a regression.
🤖 Agent: follows LivingEntity.onEquipItem (same item+components or firstTick: nothing; EQUIPPABLE on the new stack picks equip over unequip) and data merge keeps first_tick. We removed the docs/parity run-log file.
🤖 Agent: all nine families are Monster subclasses (entity.hostile.* is Monster's shared hurt/death/fall set), so HOSTILE is right; the list scan is 34 short strings per sound, negligible. We removed the docs/parity run-log file.
🤖 Agent: DataComponents.DAMAGE goes through Codec.INT (Number.intValue: truncation, Long keeps its low 32 bits), and dynamic::as_int already does that. We removed the docs/parity run-log file.
🤖 Agent: LootCommand.dropFishingLoot's no-tool endpoint passes ItemStack.EMPTY, and the code only reads tool_stack when a tool, mainhand or offhand was given, so an omitted tool stays empty. We removed the docs/parity run-log file.
🤖 Agent: Pig BABY_DIMENSIONS has PASSENGER (0, 0.5, 0), so the one match arm is right. We removed docs/parity/baby-pig-passenger-attachment.md: run logs and hashes belong in the PR description, not in docs/.
head_skin decoded the textures property (base64, JSON, URL checks) and hashed
the skin location (SHA-1) for every head on every frame, before asking the
atlas whether the skin was resident; an armor stand's worn head also turned
its profile NBT into JSON each frame. With 60 stands wearing textured heads
and 36 heads in the inventory that was ~9 us a head a frame (#4664: a server
full of menu heads, CPU-bound with the inventory open).
The pure part (profile -> textures -> skin location, failures included) is
now kept in a bounded cache beside the resolver; worn heads reuse the JSON of
an unchanged profile. The download state, atlas residency, drawn tracking and
eviction re-uploads still run per draw.
`Game::shoot_crossbow` set the arrow's weapon and Piercing count but never
ran the weapon's `projectile_spawned` ignite, which only the bow path
applied. In vanilla, `AbstractArrow`'s constructor runs
`EnchantmentHelper.onProjectileSpawned` for every arrow built with a
weapon, bow or crossbow, so a Flame crossbow shoots burning arrows that
prime TNT and set entities on fire.
The bow's `bow_projectile_ignite` becomes `ignite_spawned_arrow(weapon,
arrow)`, shared by both weapons; the crossbow ignites each arrow of its
volley after Piercing, as the constructor does. The port map rows follow
the rename, and a resource-backed regression checks no Flame, Flame and
Flame with Multishot.

🤖 Agent: confirmed in Blocks.<clinit>: water, lava and bubble_column are the only three blocks with .liquid(), so the name list is complete for Block.isPossibleToRespawnInThis.
🤖 Agent: `tick_blocks` starts a fresh `laps` after the scheduled ticks, so the stretch between `tb_entity_inside` and `tb_broadcast` shows only through `random_ticks`, `tb_scheduled` and `tb_fluids`. The counters and laps cost one relaxed load each when spans are off.
🤖 Agent: HappyGhast.getHurtSound/getDeathSound pick GHASTLING_* by isBaby, and happy_ghast::sounds already does exactly that, so the new voice_sounds arm is the whole fix.
🤖 Agent: checked against 26.3: `ChunkAccess.getHeight` returns `getFirstAvailable - 1` and `getRandomPosWithin` adds the 1 back, so topEmptyY is Horizon's `world_surface` itself. The old +1 made the bound 130 for a column solid to y 63. run-parity's natural_spawn harness checks the draws end to end.
🤖 Agent: rowing_time now gates on paddle_controller like AbstractBoat.getPaddleState (flag AND a controlling passenger) and clamps a as Mth.clampedLerp does; #10386 carries this branch merged, queued after it.
🤖 Agent: the `[false; 256]` table relies on a local palette never holding more than 256 entries (global palettes keep the per-block path). The test covers 1, 2, 256 and 300 states, a stale palette entry, and the LCG draws against an independent oracle.
🤖 Agent: matches Entity.saveWithoutId: the orb's command NBT now reads its registered uuid_for(id) instead of a fresh random UUID per read; queued first of the 10393/10422/10458 stack (the other two carry this branch merged).
🤖 Agent: `native_bake_layer` re-reads entity-models.json on every call for a vanilla layer no mob has (the doc says so), so a mod that bakes per frame would hitch; caching that document is the natural next step. The humanoid-against-zombie#main bake test is the right oracle, and the fragment stamps cleanly (tests.test_stamp_native_hooks).
🤖 Agent: the early return for an unchanged size stays ahead of the new `device.poll(wait)`, so the GPU sync happens once per real size change. A drag-resize pays it per new size, a fair price for not holding both sets of buffers.
🤖 Agent: `world_seen` never resets inside a `Custom`, so the restart on entering the Nether relies on the pack being rebuilt for each dimension. If `PackPost` is ever kept across dimensions, it will need resetting there.
🤖 Agent: only `Source::Color` gets the linear-mip sampler; shadowcolor, custom textures and the lightmap keep `Linear` (nearest level), which matches what was measured. Buffers without mipmaps read the same as before.
🤖 Agent: the 256ths weights are a fit to one NVIDIA GPU but now apply on every GPU, so an AMD or Intel reading of Iris may move them later. The cost is two floors and a multiply per filtered shadow read.
🤖 Agent: the spectator rule keys on `pack_ids.is_some()`, so a native pack's shadow keeps the first-person model, as the test pins. The other game modes stay as before, since only spectator was measured.
🤖 Agent: the +1/32 bias moves only places within one float step under a 32768th line, so #9839's water tops (29094.34) and 13/15 offsets (28398.93) still floor as before, and the new test case pins the 1, 0.5 and 9.5 edges.
🤖 Agent: with the near and far planes dropped, the shadow pass now draws every section inside the box's sides out to its reach, so a pack with tight planes draws more shadow terrain than before. Worth watching in the cave perf numbers. #10471 conflicts with this in gfx.rs; I'll merge main into it once this lands.
Both extend the boat authority fixture and harness: keep the paddle and
attack cases, both Case fields and both docstring paragraphs. The harness
keeps main's fast-profile build with #10434's --resources option.
Queued after #10434, so either landing first leaves the other mergeable.

It fires in tick_guests after the checks that skip a dead player and one on

SDL rows match a firmware version exactly, and gilrs' copy has no row for
045e:0b13 at 0x0520. The pad then falls back to gilrs' default mapping: its
right stick is on ABS_Z/ABS_RZ, which nothing read, its triggers on
ABS_GAS/ABS_BRAKE, which that mapping doesn't name, and X and Y stay crossed
because it lists C and Z.
Recognise that layout from what the pad reports, so a new firmware works

Terrain's `mc_Entity.y` was -1 on every block but water and lava, and -1 on
those too when the pack has no block.properties. Iris 1.11.7, with probe packs
of ours, reads 1 on water and lava and 0 on every other block, whether
block.properties maps it, leaves it out, or the pack has no such file.
The sprite layers' table now starts each layer at (-1, 0), with y 1 on the
fluid sprites, before block.properties is read.

A shader pack's terrain gl_Vertex floors each vertex's place in its

out a 32768th under a half block, where our probe packs read Iris
1.11.7's exactly on it: we guess, untested, that our float sums put them
a hair under the line. A place up to 1/32 of a 32768th under a grid line

each axis, the far corner's weight their product over 256 rounded half

A shader pack's shadow pass drew the block entities the camera's view
had built: a chest beside the view, in a section whose terrain the
shadow pass draws, was left out, and a spawner's mob out of the view
and out of those sections went in. Our probe packs' Iris 1.11.7 shadow
maps hold a chest wherever the shadow pass draws its section's terrain
and nothing of the one spawner in our scenes, which lies outside them.
The block entities of the sections the shadow pass drew last frame are
now added hidden from the camera, and a spawner's mob that is out of
the view and out of those sections is left out.

🤖 Agent: staged files now get the current time, so a Nightly's source unpacked with its commit's older mtimes can no longer pass for already-compiled crates (Windows/macOS fs::copy kept them); one-time stage rewrite for old stages.
A custom uniform's smooth() restarted on every frame whose camera biome was
unknown, so after each teleport it started again, and it started from the
unknown frame's values (biome -1, biome_category 0, temperature 0): the
frame that restarted it also stored them, and the first frame that knew the
biome went on from there.
Now smooth() restarts only until the first frame that knows the camera's
biome, that frame included, and then keeps going for as long as the pack
runs. With a probe pack of ours, Iris 1.11.7 kept smoothing across
teleports within a dimension and started again when the player entered

Our probe pack's Iris 1.11.7 shadow maps hold the terrain at every depth we
put it along the light (from 535 blocks beyond the shadow camera to about 120
before it), whatever shadowNearPlane and shadowFarPlane the pack sets, or
none. Horizon dropped the sections outside the shadow projection's near and
far planes; since #9768 those are the pack's own planes with no offset, so
in our probe's cave scene with the planes at 0.05 and 256 the surface toward

A NeoForge mod builds its entity models in code (createBodyLayer: a
MeshDefinition of CubeListBuilder boxes at PartPoses, a LayerDefinition),
registers them in EntityRenderersEvent.RegisterLayerDefinitions, bakes them
with EntityModelSet.bakeLayer and draws the ModelPart tree it posed in
setupAnim with ModelPart.render. Native mods get the same:
- the builders and ModelPart, ported from vanilla (mobs/model_layers.rs):
box UV from texOffs, mirror, deformation, texture scale and visible faces
as ModelPart.Cube bakes them; poses, reset_pose, get_child;
- native_layer_definitions, a collect hook asked once at start, keyed by
ModelLayerLocation ids in the mod's own namespace;
- native_bake_layer: a registered layer, or vanilla's by its
entity-models.json name (minecraft:zombie#main);
- native_draw_model_part: ModelPart.render under a mob's or block entity's
frame, textured from an atlas sprite.
The humanoid mesh built with these builders bakes to exactly vanilla's
minecraft:zombie#main (an ignored test against the prepared resources).

🤖 Agent: the kept buffer is cleared at the end of every tick, so no villager Arc<villager::Seen> outlives the tick, and #[inline] on Mob::seen only changes where each Seen is written (in its slot instead of a stack copy): same values, same order. creature_prepare 1.2 → 0.8 ms in both A/B rounds.
Options parity regression from #10092: key.emote was in the vanilla key list, so options.txt

NaturalSpawner.getRandomPosWithin draws Y in [minY, getHeight(WORLD_SURFACE)
+ 1], and ChunkAccess.getHeight is getFirstAvailable - 1: the top is the
first empty block. Horizon's world_surface already returns that block and
the spawner still added one, so every start could land one block higher
than vanilla's, in the air above the surface, where vanilla's draw never
goes; nextInt's bound was one larger too, so the draws differed from
vanilla's from there on.
🤖 Agent: idle entities (outside the simulation-level entity-ticking range) no longer run sendChanges, as in vanilla's ChunkMap.tick, so their 60-tick MoveEntityPos stops; a bare state (no data) is never paired, and the idle check follows the tracker's viewers (placed or held). tick_lan −1.66 ms (−24 %) in 3 A/B pairs.
🤖 Agent: queued. Every tracked entity now records what it rides, so any passenger (item/block display included) hides the player's tag as vanilla's isVehicle does; one risk checked: a removed vehicle leaves a stale id in passengers' vehicle, harmless since tags look up live entities.
🤖 Agent: the gate is the set of mobs the loop actually ticked (Creatures::ticked), not a second ticking-area test, so a mob that walks out of range during its own tick still finishes its pickups as in vanilla; proven against a vanilla 26.3 server (pickup_probe.py: only the ticking villager and zombie take their item).
Vanilla's LivingEntityRenderer.shouldShowName hides a name tag for any
entity with a passenger (`!entity.isVehicle()`). The client only counted
mobs, text displays, armor stands and interactions as passengers, so a
server that hangs its own name over a player with an item display, a
block display or any other entity still got the player's tag drawn
under it: two names (#5666).
Every tracked entity now records the vehicle SetPassengers puts it on,
and the name tags read that, whatever the passenger's type. The typed
lists stay for placing the riders.
The rest of #5666 was fixed already on main: the sword drawn in the
off hand by #5111 (each remote hand renders its own stack), the double
tag of custom-named players by #8457, and text display and armor stand
riders by #9754.

A pack with large buffers (SEUS PTGI at 3440x1440) held both sets at once while resizing and ran
out of video memory going back to fullscreen.

A slow tick named spawn_natural, tick_blocks and tick_creature_entities but
nothing inside them. With 100 bots they take ~11, ~21 and ~10 ms a tick, and
an index for spawn_selection's nearest-player shortlist saved nothing: the
time was elsewhere. Their steps now have laps (sn_*, tb_*, tc_*), and the
natural-spawn pass counts its attempts and spawns (sa_attempts/sa_spawns,
one note a tick). They show the attempt loop itself: ~18,850 attempts a tick
for ~3 spawns (#3910). Only when HORIZON_SPIKES is set.
Steps, landings, splashes, flaps and stepping on redstone ore come from
an entity's own tick in vanilla (Entity.move, applyEffectsFromBlocks
from LivingEntity.aiStep and ItemEntity.tick), and ServerLevel.tick
ticks only the entities in entity-ticking chunks. Here every loaded mob
and dropped item on the ground stepped on the block under it each tick:
a pig or an item that had settled on redstone ore kept lighting it after
the player went six chunks away.
Those events are now for the mobs tick_creature_entities ticked (and
those standing in the ticking area, as the sculk fixture posts before
the mobs tick) and the items in the ticking area. A mob that did not
tick keeps where it is as its last position, without a step. Damage and
mounting are raised by hurt and startRiding, so they stay for every mob.

tick_creature_entities snapshots every loaded mob (`Seen`, ~400 bytes)
before the loop and again after each mob's tick. Mob::seen lives in the
client lib and was not inlined into the game crate, so each one was
built on the stack and copied into its slot, and the snapshot's
megabytes were allocated and freed every tick.
Mob::seen is #[inline] now, and the emptied buffer stays in Creatures
for the next tick. The snapshot holds the same values.

Part of #9998.
Startup parsed entity-models.json (2.4 MB) into a serde_json::Value six
times: for the handoff's GameCpuResources, MobTypes, the player type, both
player arm models and the spin-attack model. The rest worker did five of
those one after another. Nothing in the document changes during a loader
generation, and a pack change starts a new one.
load_resources now parses it once on its own step beside load_core and
shares it as an Arc<EntityModelDocument> with every model loader. A
missing or malformed document leaves each caller on its old path, so
errors and fallbacks are unchanged; a dedicated server draws no models and
skips the parse.
Callgrind, the whole resource load in the game (to "resources loaded"):
21.576 G -> 20.631 G instructions (-4.38%); the entity-model path alone
1.594 G -> 0.349 G (-78.1%). A new test builds MobTypes from a shared
document and from its own parse and compares every type, model and layer.

light_chunk filled its 48x48xheight region from every non-air section by
unpacking 4,096 state ids into a scratch array, then reading each one
back, looking up LightTables::info and storing 2 of its bytes. That round
trip was 35% of a light job, and the flood fill only ever reads those 2
bytes.
PalettedContainer::unpack_ids_mapped decodes the packed storage through a
lookup table in one pass (out[i] = map[id of entry i]), with a fast path
for 4 bits per entry, a linear palette's usual width. light.rs's new
states_of maps a section's palette to the packed light info once (at most
256 entries), then copies the region's 16-wide rows from the staged
values. A section whose palette emits light stages full infos and seeds
block light and the queue per cell, in the same order as before. Air now
writes info[0], which is 0, the value the region already holds (asserted
in debug builds).
Callgrind, gen_light_bench --seed 1234 --radius 4 --threads 1 (81 lit
columns): the light job 1.991 G -> 1.260 G instructions (-36.7%), the
whole run -1.15%. The light job is 5-7% of the workers' CPU, so this is
about 2% of the chunk pipeline.
Exact: gen_light_bench's block and light checksum is identical for three
seeds and centres at 1 and 4 threads, light_chunk_matches_old_algorithm
(an independent light implementation over random 3x3 regions) passes
unchanged, and the new section_states_match_the_unpacked_ids compares
states_of with a walk over unpacked state ids for one value, 4 to 8 bits
and the global palette, with and without light sources.

A killed exporter left an empty gameplay-facts.json (or another table) behind.
The preparer only checked that the path exists, so "prepare again" kept the
empty file, and the launcher called the folder prepared and started the game
on it. Trust an earlier export only when it still parses, and treat a folder
with an empty top-level JSON table as not prepared so Play prepares it again.

All 19 new lock packages are permissive (MIT/Apache/BSD-3/ISC-style webpki/Zlib/BSL option on ryu); the only build scripts (mysql, mysql_common) just pass target env vars, no downloads; TLS is rustls+ring only, flate2 uses miniz_oxide, no openssl/native-tls/-sys/cmake. cargo tree for horizon-client (default, --no-default-features, --target all) is identical to main, so players' game and native-mod compile are unchanged; the launcher's cold cargo fetch gains 21 crates / +2.5 MB once (noise in wall time). Note for later: webpki 0.22 and rustls-pemfile are unmaintained upstream; worth moving to mysql 28 when it no longer rewrites the lock.
serde's "expected value at line 1 column 1" says nothing about which of the

While Tab is held every frame sorted every entry twice (once for the faces,
once for the rows), allocated team keys inside the comparator, rebuilt and
measured every row's text, split the header and footer, and pruned the
health states with a scan per row (#10108). TabList now keeps the sorted
order and the laid-out rows, rebuilt only when their inputs differ (players,
scoreboard, header/footer, width, font and language); the faces reuse the
order; sort keys are borrowed; the health states go by a uuid set. Hearts
still animate every frame.
Mob.aiStep's looting, the villagers' item sensor and the fox, dolphin,
panda, piglin, allay and sulfur cube item passes run after the mob loop
over every loaded mob. In vanilla they are part of the mob's own tick,
and ServerLevel.tick ticks only the entities in inEntityTickingRange: a
villager six chunks from the nearest player, loaded but outside the
simulation distance, took the bread at its feet here and not there.
The loop records the mobs whose tick ran (Creatures::ticked), and those
passes leave the others alone.

In adventure mode, vanilla allows ItemStack.useOn if the item's can_place_on component matches the clicked block. Previously, use_map_on_banner checked only !self.may_build() and returned early without checking can_place_on.
This honours can_place_on_in_adventure on the banner's block position, allowing adventure mode players with matching maps to toggle banner markers.

🤖 Agent: each mob footstep scanned every mob three times (two id lookups and the warden/allay listener loop); now an event with no sculk block in reach and no warden or allay within 24 blocks skips the context and the listeners. Listeners give up past 16 blocks before any side effect, so vibrations are unchanged.

🤖 Agent: launcher-only fix. Maps the service's 403 use_checkout / not_offered_here to their own messages (86 tables), and drops one_click after use_checkout so the Shop opens the free checkout. Risk: none on the hot path; only the claim's error branch changes. Launcher tests 719 passed on the desktop.
🤖 Agent: villager_pickups tested every loaded villager against every dropped item, looking up tags before the reach: that was 12.8 of 23 ms of the mob phase in the load test (22.7 → 8.1 ms after this). The new ItemScan keeps the full scan's order and falls back to it if the item list changes under it.
🤖 Agent: merging. Every knock_back caller outside the legacy rules passes legacy = false, so the 26.3 path is unchanged. 1.8's air lift and the unhalved sprint push only run under the hosted-world switch.
The cosmetics service answers POST /v1/claim with 403 use_checkout where
Paddle sells (the set goes through its free checkout there) and 403
not_offered_here where the claim is left out. The launcher mapped neither,
so a player saw "Horizon's cosmetics service had a problem" (Discord bug
thread, 2026-11-05).
- Both codes are the Shop's own refusals now, each with its own words, in
all 86 lang tables.
- After use_checkout the saved answer drops one_click, so the Wardrobe stops
offering "Claim for free" and the Shop's button opens the free checkout on
playhorizon.dev.

🤖 Agent: merging. [combat] is only written when legacy is on, and unknown keys are rejected. The game reads it in dedicated.rs, and a bad section logs and keeps 26.3's rules. The test now looks for the section line, not the template's '# [combat]' comment, which made verify fail on the first head.
🤖 Agent: merging. legacy_rules() is remote.is_none() && combatRules, so a window on any server keeps 26.3's cooldown and damage. Measured over LAN: 1.8 rules 7 and 7 (diamond axe, charged then right after a swap), 26.3 9 and 3.6.
Every frame built, styled and measured the name tag of every player within
64 blocks, drawn or not: with 150 players and the camera facing the sky that
was ~0.74 ms a frame (#4664). A tag is now built only for an entity vanilla
would render, its culling box grown by 0.5 in the frame's frustum
(EntityRenderer.shouldRender), checked before any text work; armor stands
likewise. Status and native snapshot queries still see every tag.
other_players finds each player's entity through one id->index map instead
of scanning every entity per player (the first match, as iter().find).
🤖 Agent: merging. The 1.9 hit sounds and particles are filtered on receipt (remote.rs, lan_particles.rs), so nothing sent changes. Hurt sounds and crit particles stay, and 1.8 hit sounds are off by default.
Remove the blanket trait-mod presence bypass while preserving shader-pack guards. Verify the projected shadow in a game with an active native camera hook.

🤖 Agent: merging. Legacy only moves the hand's matrices, and only for items with vanilla's flat display (pack-moved and post-1.8 items keep 26.3's). It's off by default, and the renderer is the only reader of the equip state it changes. On scripted fights against a vanilla server, #10117's Modern-vs-Legacy packet comparison matched on every scenario that is stable between two identical clients.
Zoom moved from the built-in extras to Horizon's official native mod
(#2030), so the Extras page lost its Zoom setting. Players looking for it
there, including the macOS report in #8713, found nothing.
The Extras page now keeps a Zoom row: with the mod built in it is the mod's
own on/off switch plus a Settings button that opens its page; without the
mod it opens the Mods page where it is installed. The cause is not
macOS-specific: every platform lost the row when Zoom moved.

The shader screen (shader_ui) draws the pack list and every pack's settings,
so the options screen's own rows for them go: the Shader Packs and Shader
Options button lists, a Horizon pack's option pages, their actions and the two
pack slider kinds, with the label fitter only they used and the four lang keys
only they read.
A button that pushes the Shader Packs page (as one on the Options screen would) listed the packs but left the picked pack's settings unread until a pack was picked again. Every way into the screen now reads them with the list.
A mob near some dropped item tested every item on the level (2,000 in
the load test: 1.5 ms a tick). ItemAreas now keeps the items of each
cell, and ItemScan walks the list in its order from one item in a met
cell to the next, testing what the scan tested; it keeps up with the
items the walk removes, and tests every item from there on if the list
changes any other way. The villagers' pickups walk the same way.

Shader Packs... opens a screen in the frame of the graphics and controller
settings (settings_shell) instead of two vanilla button lists. Its first page
lists the installed packs (a tick box on the one in use; picking it again
turns shaders off), the pack folder, and Horizon's own Shadow Cache under
"Built-in settings". Under the picked pack's name, the page list holds the
pack's own screens (a shaders/ pack's screen.NAMEs, a Horizon pack's
[[pages]]), as "Pack settings": switches, sliders, choices, profiles and links
to deeper screens, with the pack's own descriptions in the strip. The search
finds an option on any of the pack's screens. A shaders/ pack's changes apply
with Apply or when the screen closes; picking another pack keeps the last
one's changes first.
MinecartHopper.tick has no transfer cooldown in 26.3: it calls tryConsumeItems every tick, and consumedItemThisFrame caps a tick at one item even when makeStepAlongTrack tries too. The reported pre-#2250 whole-stack pickup is gone; add the regression test that catches it coming back, and cite the per-frame cap next to hopper_cart_suck.

The launcher traced a compile error to a mod only inside the helper function itself. horizon-mixins
wraps each helper in a block that calls it, `{ fn helper(…) { … } helper(…) }`. When Horizon
changes a type the helper's signature mentions (flair 1.0.0: `extra` became five-element tuples),
the error lands on that generated call, so no mod was named and the whole build failed instead of
leaving that mod out. A block holding only the helper and its call now counts as the helper's.

HORIZON_SPIKES named almost nothing inside bench's prepare phase: with 150
players on a server and the camera facing the sky, prepare took ~0.43 ms a
frame and its spans accounted for ~0.005 ms. Each step between the fixed
ticks and the renderer now has a lap (pr_hud, pr_entities, pr_lights,
pr_frame, ...), dynamic lights two finer ones. They showed the cost: name
tags (eg_name_tags) built every frame for every player, drawn or not (#4664).
A resident column the server sends again was always relit here, for a
Horizon server's bulk edits whose packet carries the light from before
its relight. A proxy's next server resends its whole world at the same
coordinates, so every column queued light jobs for itself and its eight
neighbours, which a small CPU could not work through.
Relight a resent column only when the server announced Horizon's quiet
commands, the same feature flag Horizon servers send in configuration;
any other server's packet light is final, as vanilla applies it. A
reconfiguration resets the announcement until the new server sends its
own.

From review, each measured against vanilla:
- DragonHoverPhase.getFlySpeed is 1, not the default 0.6: a hovering dragon thrown upwards
climbs back at vanilla's rate (new harness case, 12 commands off before).
- wrap / wrap64 are Mth.wrapDegrees: Java's % then one step of 360. rem_euclid lost the low
bits of a negative angle (-10.123456 became -10.123444) every tick (unit test).
- The parts' placement, the strafe aim and the flap timing use Mth.sin / Mth.cos and vanilla's
float casts.
- DragonSittingScanningPhase turns only while the player is more than 10 degrees off the
heading, with Mth.atan2 and vanilla's degree constant; dist is clamped in both divisions.
- A dragon's parts start at the origin, as vanilla's part entities do until the first aiStep,
so its first scanning turn aims from there.
The command execution harness gets "dragon scanning turn" (a dragon facing a survival player and
one turned away): 6/12 before, 12/12 now. All dragon and End harnesses match; the whole command
execution harness: 15832/15832.

🤖 Agent: merging the mod hot-load design note, docs only. The point to check is the native measurement it rests on: a one-line gameplay change rebuilds in 570 s against 812 s cold, and mold doesn't help, which is why the run-time switch came before background builds.
🤖 Agent: merging live switching of content mods. The point to check is the server's world tables: with no data pack they used to stay on the startup resources, so a switched mod's data never applied. After a live switch they are now built from the new root (data_switched), checked in game by a mod function that loads, unloads and loads again.
GLSL asks a texel offset to be a constant expression; GL drivers also take one a
function receives as a `const in ivec2` parameter (Arc's FXAA samples its neighbours
that way, so its final pass was skipped in every dimension). Such an offset now moves
the coordinate by that many texels of the base level; a constant one stays an offset.
The biome categories and precipitations custom uniforms compare with are defined for the
GLSL as well, with the same values: Sildur's Enhanced Default reads
`biome_category == CAT_THE_END` in gbuffers_skytextured, which failed on the unknown
name. BIOME_* still needs the world's registry and stays in custom uniforms.
Three things GL drivers take that naga's GLSL front end refused:
- an empty declaration (`;`) at global scope in any version, as a macro that writes a
function leaves after it (DrDestens: 56 programs skipped);
- a precision qualifier on a function parameter (`float rand(highp vec2 p)`,
TrailerShaders: final and composite);
- a constant expression in a function whose value is infinite or NaN
(`1.0 / toeX` with toeX 0, Epoch's tonemap at its defaults): it is computed at run
time, as GL does, instead of folded into a literal that can't hold it. WGSL keeps
refusing it.
GLSL lets a pack sample a usampler2D or isampler2D with texture(); GL drivers read an
integer texture with nearest filtering, so it is the texel the point falls in. naga
rejects sampling an integer image, and Mello, Voyager, Exposa and Reverie lost the
programs that read their integer colortex buffers that way (Mello 20, Voyager 42, Exposa
48). Those calls now go to helpers that texelFetch the texel under the point, clamped to
the edge, at level 0 (textureLod: the level it names).
`const vec4 s = vec4(scale[0].x, ...)` over a constant array read the index and the
array from the function's arena while folding in the module's: naga panicked (index out
of bounds) and Ebin Resurrected failed to load. Both now come from the global arena.
A panic in one pack no longer stops the run: it is caught, and each pack ends with a
SUMMARY line of the programs skipped in each dimension. A pack without shaders.properties
keys is read as one (every key at its default), not a failure.
`mat2(v)` with a vec4 `v` is the matrix with columns v.xy and v.zw in GLSL, as when the
components come as several arguments. naga's GLSL front end made each column the whole
vector, which failed validation ("Composing 0's component type is not expected"):
Bloop's water normals (prepare1) were skipped.
Packs compare block ids with Distant Horizons' block materials outside any
DISTANT_HORIZONS guard (Exposa: `blockID == DH_BLOCK_LEAVES`), so Iris defines them in
its standard macros whether the mod is there or not. Exposa's composite and composite1
failed on the unknown names; DH_BLOCK_UNKNOWN to DH_BLOCK_ILLUMINATED are now 0 to 15,
the mod's EDhApiBlockMaterial numbers.
GLSL asks a fragment input of integer type to be `flat`, but since 4.30 only the
fragment stage's interpolation qualifier counts: a vertex stage may write
`out uint frag_worldTN;` and GL drivers link it to `flat in uint`. naga left such an
output without interpolation and refused it (Alpha Piscium: 111 programs). An integer
vertex output or fragment input with no qualifier is now flat.
`colors2_colorspaces_ ## a ## _to_ ## b ##(x)` (Alpha Piscium) pastes the name's last
part to its `(`. The preprocessor made one token of `..._6_to_8(`, which named no macro,
so the call to the function-like macro `colors2_colorspaces_6_to_8` was left for the
compiler as an unknown function. As GL drivers' preprocessors do, the paste now stays the
tokens it is made of, and the name is rescanned with its `(`.

🤖 Agent: the request log reads the player's name before the request runs, so a release or drop that removes the guest still logs who it was. The e2e this PR adds ran on this exact stack against current main: 31/31 over real control sockets with horizon-bots.
🤖 Agent: pushed 4020e2537 for martipops' review. It refuses a rotation that overflows f32 (1e39 became inf/NaN after the cast), refuses a named position when the record still has a RootVehicle to restore (the vehicle would undo it), keeps recentered on retries, and documents that velocity is the server's body only. Tests added for each; union-tested on the desktop.
🤖 Agent: the commit point holds. place_arrival writes the .dat with write_dat_durable plus the advancements and stats with write_durable, each a Result, before ok, and the player stays held on any error. Retries after the commit answer through placed_arrival. martipops' two reviews are answered point by point in the comment above. server_transfer_e2e passed on the final stack (31/31).
🤖 Agent: with [transfer] off, no login is expected, so held stays false and watches() equals here(): every here→watches swap in hub.rs and the loading_chunks refactor are no-ops for ordinary servers. With it on, a held player is a viewer but not tracked, and gets list changes through broadcast_watching. Union-tested with main and the stack on the desktop, plus server_transfer_e2e (31/31).
tick_mob_sculk_events posts every loaded mob's footsteps, landings and
splashes. Each event looked its mob up by a scan of every mob (for the
context and the supporting block) and asked every mob whether it was a
warden or an allay, so a server with thousands of mobs paid three scans
of them for each footstep near no listener.
Now, as GameEventDispatcher only visits the listeners around the event:
while the mobs' events are posted, mobs are found by id through a slot
map, the wardens and allays are listed once with their positions, and
an event with no sculk block in reach and no warden or allay within 24
blocks skips the context and the listeners. A mob that stands as it
stood with no step due (every mob outside the simulation distance)
leaves at once, and a mob riding nothing, as before, skips the mount
bookkeeping. Mods still get every event (native_game_event).

villager_pickups tested every loaded villager against every dropped item,
looking the item up in the villager food table and tags before the reach:
on a server with hundreds of villagers and thousands of items that was
most of the mob phase. The reach comes first now, and a villager with no
item in its cells skips the scan (ItemAreas, as the looting passes do).
Mobs outside the simulation distance only check despawning, which reads
the nearest player and the difficulty: they no longer copy the player
view they see. A ticking mob borrows its guest's view for its tick (the
tick reads it through &MobWorld) instead of cloning it.

🤖 Agent: unknown states now read as air at the three places they enter (chunk palettes, block updates, BlockFacts::get), and the palette scan is skipped when nothing is unknown, so a vanilla-width chunk costs one maybe_has over its palette. Vanilla would disconnect on such an id (MissingPaletteEntryException) instead; air matches what Horizon already did for a wider host, so I took it. Union-tested on the desktop (clippy, wide_states, horizon-items).
🤖 Agent: removing JAVA_TOOL_OPTIONS, _JAVA_OPTIONS and JDK_JAVA_OPTIONS in java::command reaches every exporter JVM and javac but not the game's own launch, so a player's global -XX:+UseZGC still applies in play and only stops clashing with BATCH_OPTIONS' SerialGC during preparation. Built and tested in a union on the desktop (clippy, horizon-prepare tests).
Answers martipops' review of #8735:
- A rotation finite as f64 but past f32::MAX became an infinity (and a NaN pitch) after the
cast; it is refused now, like any rotation that is not a number.
- A record with a vehicle still to restore (RootVehicle) seats the player back on it at the
vehicle's own place, which undid a position the request named; the two are refused together.
- A retried import of the same hand-over, or a retry after the commit, answers the same
`recentered` as the first reply (kept on the guest until it is placed).
- docs/server.md says the velocity is the server's only: the arrival's teleport carries no
motion, as a vanilla login's does not.

ChunkMap.tick runs ServerEntity.sendChanges only for an entity that changed
section, needs sync, or is in DistanceManager.inEntityTickingRange. Horizon
ran it for every tracked entity, so an idle one sent its position every 60
ticks and advanced its update clock. EntityState::idle now carries the
range (the simulation level, Levels::in_entity_ticking_range), and the
tracker skips sendChanges for an idle entity that stayed in its section and
needs no sync; a lead change still goes out at once (Leashable).
The game then stops describing such entities in full every tick: an idle
mob or item that was in the tracker's last pass at the same place, carries
no passengers, and is already tracked by every client within its tracking
range is described bare (where it is, none of its data). The tracker never
reads its data and never pairs a bare state, so every pairing still sends
the entity as it is (game/lan_idle.rs).

draw_tab_list ran every frame and, through remote_tab_players, cloned every
listed player and formatted two object-skin keys for each before it knew
whether the list was shown; update_remote_skins then searched every entity
once per level player and cloned the whole skin map. With 150 players and
none drawn a frame still cost ~0.4 ms more than with none (#4664).
- The list's visibility comes from the listed count; the players are built
only while it is shown or when it opens/closes (narration).
- The id:/name: object skins publish only when a player, its skin or the
atlas's object skins changed (a fingerprint and an atlas revision), so
inline faces keep the server's skin as before.
- update_remote_skins finds players and mannequins through one id->index map
and moves the resolved skins in instead of cloning them.
🤖 Agent: merging. The default --clients vanilla,horizon run is unchanged, and so is main's one-client capture (now 'one or two of'). horizon-legacy only adds a horizon-extras.txt in its own scratch home. On the desktop, Modern vs Legacy matched on 14 of 16 scenarios; eat and dig_teleport also differed between two identical Modern clients there.
🤖 Agent: merging. Pictures are now sized to the window × scale and capped by the atlas limit (the wgpu adapters' min on Linux, 16384 on Metal/DX), instead of a fixed 3840. RSS stays flat at 173 MiB for 5 min on a real GPU. One thing to watch: the Linux probe opens its own Vulkan/GL instance at startup on a background thread, and until it answers pictures cap at 8192.
With a stitched colour atlas (sprites at their own sizes), the normal and
specular atlases were still packed as a grid by PackAtlas::material, so a
block's material texels sat under another sprite's colour (#9570). The
companion atlases now reuse the colour atlas's size, rectangles and padding;
each map is nearest-sampled from its single level into its sprite's
rectangle (an fs_material entry point), and animated sprites copy into the
same rectangles. The grid path is unchanged.
EnderDragon's constructor sets EnderDragonPhase.HOVERING; only EnderDragonFight.createNewDragon
sets the holding pattern. Dragon::new started every dragon holding its pattern, so a dragon from
/summon, a spawn egg or a save without DragonPhase flew off. It now starts hovering, and
create_new_dragon sets the holding pattern.
Hovering had never run on the server, and the flight step diverged there: the target is a hair
away, where Vec3.normalize returns zero under 1.0E-5 and vanilla's Mth.sin/cos table and
Mth.atan2 turn the dragon differently from the exact functions. The step now uses them, the
doubles of moveRelative's input vector and vanilla's 0.91F and 0.8F as doubles.
The command execution harness gets "summoned dragon hovers" (phase and position every 20 ticks
over 120): 0/13 before, 25/25 now. The dragon harnesses (server dragon, contacts, NoAI, not the
fight's, death outside the End, death roar, forced End, spawn eggs in fluids, dispensers) match.

In the glass theme account settings (skin_panel), long translated option
labels such as French 'Bras classiques' protruded outside the segmented
control pill due to an inherited ml(40px) margin and cross-axis stretching.
Additionally, the multi-sentence caption wrapped into a 10-line block inside
the narrow column, clipping off the bottom on 1080p displays.
- Remove the ml(40px) margin in glass theme mode.
- Set items_start() on the control column so segments size to natural width.
- Adjust segments option padding to 12px with flex_none and justify_center.
- Reorganize skin_panel so the caption spans full width across the bottom.
- Adjust Microsoft card width to 360px and reduce vertical padding in glass_who_plays.

Join a Friend opens from the title screen's Friends button and from the
server list. Both exits always went to the server list, so the title's
entry landed the player on a list they never opened (#9190, item 10).
The page now remembers whether the title opened it.
#10236 capped screenshots and the background at a fixed 3840 px, so an
8K screen lost detail. Pictures are now made at what the screen shows:
- viewer and background: the window's longer side x its scale factor
(7680 px on an 8K screen), tiles 360 points x the scale factor, in
256 px steps so a resize doesn't remake them every frame;
- never above the biggest texture GPUI's atlas holds: on Linux the
smallest max_texture_dimension_2d over wgpu's Vulkan/GL adapters
(asked once in the background, 8192 until known), elsewhere the fixed
16384 of the Metal and DirectX atlases. A larger picture would make
the atlas add a max-size texture on every frame (zed#66595).

A save can now name an entity it only knows as a `Who`: `mob_to_nbt` takes a
`uuid_of` resolver, `who_uuid` writes a `Who` as a UUID and `who_by_uuid` turns a
stored UUID back into the `Who` of a loaded player or mob. `EntityMemory::uuid_of`
supplies the id -> UUID map the game layer keeps, and the game layer's `mob_by_uuid`
now resolves through the same seam.
The neutral mobs' `angry_at` is the first writer: anger at another mob now saves
that mob's UUID instead of nothing. The warden's suspect list and the shulker
bullet's target are the two follow-ups this bridge unblocks; neither is written
here.
Under Linux, executing a freshly copied test fixture can fail with ETXTBSY (os error 26) if another test thread forked while the file was being written. Copy the fixture via a temporary file before renaming it into place, and retry exec/spawn if ETXTBSY occurs.

With the legacy rules on, a player's knockback follows 1.8.9's
EntityLivingBase.knockBack: the motion halves and the 0.4 push lifts in the
air too (26.3 lifts only from the ground), and knockback resistance is a
chance to take none instead of a cut. The sprint and Knockback push is added
on top as attackTargetEntityWithCurrentItem's addVelocity (0.1 up) instead
of going through knockback, for players and mobs alike.

horizon-server accepts and keeps a [combat] section (off by default, left out
of the file while off); the dedicated game reads it itself, like
[anticheat], and turns on the legacy rules a hosted world's PvP page switch
gives. A wrong section is logged and fights keep 26.3's rules.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Under Combat feel Legacy the client draws no sweep_attack or
damage_indicator particles a server sends (1.8.9 had neither), and with
'1.8 hit sounds' plays none of the entity.player.attack.* sounds 1.9
added. Hurt sounds, crits and enchanted hits stay. Only what this client
shows changes; nothing is sent.
1.8.9 drew no red tint over armour (LayerArmorBase.shouldCombineTextures
is false, so setBrightness skips it) and the body's flash is red at 0.3,
as 26.3's: both already match.

Combat feel: Modern (default) or Legacy (1.8.9). Legacy changes only the
picture: a flat item in first person takes 1.8.9's ItemRenderer pose
(swing, eating and drinking, bow pull) through 26.3's own display
transform, a sword is held up while use is held (1.8.9's block pose,
swinging as 1.7.10 did), the main hand no longer dips after each hit,
and the attack indicator hides unless the player keeps it. The clicks
and every packet stay 26.3's. Poses 1.8.9 lacked (crossbow, trident,
spear, brush) and resource packs' own displays stay modern.

A PvP page switch, off by default: single player and LAN worlds resolve
melee hits by 1.8.9's rules (EntityPlayer.attackTargetEntityWithCurrentItem):
no attack cooldown and no sweep, 1.8.9 weapon damage (ItemSword 4 / ItemAxe 3 /
ItemPickaxe 2 / ItemSpade 1 plus ToolMaterial), Strength x(1 + 1.3 per level)
and Weakness -0.5 per level, Sharpness 1.25 per level, and critical hits that
allow sprinting and need no charge. Only a game that is the server uses them;
a window playing on a server never does, so what it sends stays the same.
The window passes the switch to its server thread each frame, like the
distances. lan_e2e's legacy-pvp check measures two diamond axe hits 12 ticks
apart: 7 and 7 under the rules, 9 then a cooldown-cut hit without.

🤖 Agent: merging. These are #10079's commits merged with main and nothing else; #10079 had landed in the already-merged pvp/hud-layout. The editor opens only from a world and is the only screen that writes the layout.
🤖 Agent: verified on the desktop: horizon-mods 36 tests, launcher 589 tests, clippy -D warnings clean. broken_on is read only from the registry index (the publish job adds it from horizon-mods' daily native-compat run). The warning shows only when the entry's Horizon is the commit the mod would build on, so a mod pinned elsewhere doesn't warn.
🤖 Agent: the harness itself: 16 scenarios, real vanilla 26.3 client vs Horizon, per tick and field; on main 11/16 match, with the series + #9918 16/16. Named-only and solo in parity_hosts (needs a virtual screen, ~15 min). Merge of main resolved a game.rs mod-list conflict (tick_profile + tick_script).
🤖 Agent: wire stream harness (#10082) on main: number keys' SetCarriedItem left a tick early (hotbar_swap, 15 ticks; dig_teleport) and a key tapped with a swing at the sky sent the slot before the Punch; with this change every tick matches vanilla. Head = cc7200cd7a's +35 −43 plus merges of #10083, #10085 and main (conflicts in remote.rs resolved to the tree the harness after-run built and passed).
🤖 Agent: verified end to end on the desktop: with 30 registry mods on Nightly 2026-11-05, main's launcher fails the whole build (eatinganimation E_TARGET_NOT_FOUND), and this one builds 22 and leaves out 8 with their reasons. MIXINS_REV moves to 5a64af9 (horizon-mixins#27, #28). The risk to watch: a compile failure costs one full recompile per round, capped at 3.
Stereo music and records were downmixed to mono and panned by the camera, so turning away hard-panned them and distance attenuation could silence them. OpenAL Soft plays a multi-channel buffer without spatialization or distance attenuation (AL_SOFT_source_spatialize auto), as vanilla's HRTF-off context does.
Keep the decoded channel count through the cache and mixer; mono buffers keep the existing panning and linear attenuation. Add a mixer test that stereo frames stay direct and unattenuated at any camera angle or distance.

Vanilla's Math.sin is HotSpot's intrinsic, which rounds one of the drop
test's throws a bit lower on AArch64 than on x86-64; a vanilla 26.3 run
on an M-series Mac gives the AArch64 value. The install.sh fixture only
holds the Linux x86-64 archive and ran the cases with /usr/bin's
OpenSSL, LibreSSL on macOS: a fake uname picks that archive, and the

🤖 Agent: bridge in the wire stream harness: 19 of 19 UseItemOn cursors differed from vanilla by ~6e-5 on main (double trig in the pick ray), all bit-identical with Mth's float table. Hot path cost: one table lookup per frame instead of libm sin/cos.
🤖 Agent: read against LocalPlayer.sendChanges and AbstractBoat.tick (rider look, vehicle, then sprint; paddles first). No riding scenario in the harness yet, so the proof is the read and the unchanged 16 scenarios. Land before #10084, which merges this branch.
🤖 Agent: verified with the wire stream harness (#10082): on main, dig_teleport answered a teleport mid-dig with a new START (sequence 34) instead of vanilla's ABORT; with the series every tick matches. pr_ready clean except the desktop nix-shell's uname-less install.sh test.
The held slot leaves remote_send_state (this PR); the boat's paddles go first and a
passenger sends its look, vehicle, then sprint (#10085).

A loaded desktop's vanilla client failed to log in; rerunning Horizon alone and
comparing with the earlier vanilla capture crashed on the missing client.

From review:
- A perched dragon shrugs off a direct arrow, trident or wind charge given as `by`
(AbstractDragonSittingPhase.onHurt is 0, under 0.01): the command is refused.
- dealDefaultKnockback: a counted hit of a type not in #no_knockback pushes the dragon away from
the command's source position (`at`, else the direct entity), or in no direction without one.
- credit_dragon_kill switches to the credited guest whenever they are not the one acting, as the
mob kill credit does, so a guest's command that credits another guest awards that guest.
The harness scenario summons its dragons holding their pattern (DragonPhase 0): vanilla summons a
hovering dragon, which is sitting, and Horizon one holding its pattern; that gap is separate.
The intermediate build: 36/39; now 39/39.

🤖 Agent: the keyboard path is a mechanical move from keys.contains to held(Action), with the same default keys underneath; old horizon-controller.txt files keep their buttons (no bindLayout line), and the pad's stack drop also reaches the server path through drop_stack. Union pr_ready green.
🤖 Agent: the check is SocketAddr::from_pathname, and the test compares it with a real bind at every length 1-150, so it follows the OS limit (104 on macOS, 108 on Linux) without a hardcoded number.
🤖 Agent: SOCKS goes through ureq's own socks-proxy feature (socks 0.3.4, MIT/Apache), and the loopback SOCKS5 test proves the request reaches an .invalid host only through the proxy. Nothing changes for players without a proxy set.
🤖 Agent: matches 26.3: OptionsList inherits AbstractScrollArea.mouseScrolled, so the wheel scrolls the list and never reaches a row's CycleButton; the old key is dropped because every install saved it as true. Main merged in, union pr_ready green.
Client mods that bake from the world in bulk (a minimap's tiles, a world
map export) had to clone `game.world.chunks` and read `world_biomes!`,
which pins them to one Horizon commit. Four stable helpers replace that:
- `native_client_chunks(from, to)` shares the client world's loaded
chunks of an area as `NativeClientChunks` (Send + Sync): block state,
biome id, loaded, each column's top non-empty section, build height.
- `native_client_chunks_changed(&snapshot)` names the chunks that differ
from the snapshot now. A held chunk is copied before any edit, so the
same allocation means the same chunk.
- `native_client_biomes()` gives the biome table the terrain is drawn
with (`NativeClientBiomes`): names and tints by `NativeBiomeId`.
- `native_client_biomes_changed(&biomes)` says when that table was
replaced (a mod's seasons, a resource reload, another world).

Aligning every tick after the teleport on its acceptance moved the script's own

🤖 Agent: harness and examples-only probe, nothing players run. New head: CI's parallel shards raced on one schematic .part file; each process now writes its own (three concurrent downloads checked against the pinned digest), and parity / parity passes.

The second end-to-end build of 30 registry mods on 6475f62 stopped on
errors inside carryblock's, distant_horizons', smartf3's and treefall's

injected helpers were traced. An error inside the inline module a mod
declared (one the pristine source doesn't have) now names that mod, so

A windowless game with a resident chunk, a jukebox at (0, 64, 0) and a disc put
in through use_jukebox: 41 ticks of the jukebox tick post the event at ticks 0,
20 and 40 and nothing else, and a jukebox that is never played posts none.
JukeboxSongPlayer.tick posts GameEvent.JUKEBOX_PLAY at the block every
PLAY_EVENT_INTERVAL_TICKS (20) ticks of a song, right before the music
particles:

44: getstatic #101 // Field GameEvent.JUKEBOX_PLAY
56: invokeinterface // LevelAccessor.gameEvent:(Holder,BlockPos,Context)
66: invokestatic #104 // Method spawnMusicParticles:(LevelAccessor,BlockPos;)V
Horizon drew the note particle in the same twenty-tick branch and posted
nothing, so a sculk sensor beside a playing jukebox never clicked and an allay
never heard the song, although the stop half (JUKEBOX_STOP_PLAY with level
event 1011) was already posted when the jukebox went away.
cmd_damage had no arm for them, so both said "Target is invulnerable".
EnderDragon.hurtServer is hurt(body, ...): a quarter plus up to 1; reallyHurt runs only with a
player behind the source or an #is_explosion type and refuses fire, and hurt succeeds either
way unless the dragon is dying or the hit is under 0.01. EndCrystal.hurtServer refuses an
Invulnerable crystal (unless generic_kill, out_of_world or a creative player), fire and the
dragon's own damage; else it is removed, and blows up unless the damage is an explosion.
The command execution harness gets a "dragon command damage" group: 15/31 before, 31/31 after.

A windowless game from the prepared resources, a bow in hand: the two events the
use posts are read back from the game's own event recorder, at the player's feet
(10, 64, -4). A spear, whose use effects set interact_vibrations false, posts
neither.
LivingEntity.startUsingItem ends with
this.useItem.causeUseVibration(this, GameEvent.ITEM_INTERACT_START), and
ItemStack.causeUseVibration posts only when the stack's use effects ask for
interaction vibrations - the same gate and the same position stopUsingItem
already used for ITEM_INTERACT_FINISH. Horizon posted only the finish event, so
a sculk sensor beside a player drawing a bow never clicked and an allay never
heard the use start.
use_vibration takes the event now, and start_using_item calls it where vanilla
posts it: after the use is set up, before the kinetic weapon's map (which this
change leaves alone).

VanillaRedstoneCatalogOracle builds each contraption (block states and
block entities the harness reads from its schematic) in the overworld of a
real flat-world server, one contraption per server tick. Comparators keep
their saved output, containers and lecterns get real items (set silently:
no comparator ticks, no lectern pulse), and the comparator level of every
block entity is printed for the Horizon probe. The game clock keeps
running between contraptions (LevelTicks orders chunks by trigger time);
the probe starts from the time printed.
Levers and buttons are driven with useWithoutItem, and each tick runs what
ServerLevel.tick runs for blocks: scheduled block and fluid ticks, block
events and block entities, so pistons move. After each tick it prints the
outputs that changed, and at the end of each step the tick it ended on,
whether the level went quiet and a hash of the contraption's box. A tick
budget per contraption (the probe counts the same) bounds machines that
never settle; containers at or next to hoppers, droppers, dispensers and
crafters are watched every tick, and a changed level marks the run as not
comparable (the probe does not move items). HORIZON_CATALOG_TRACE=1 adds
every block tick and every block at a step's end.

The three vanilla dimensions, built from the shipped data, must answer what
their noise settings say: the overworld and the nether add creature packs at
generation, the End does not. This is the value `spawn_generation_creatures`
now returns on, read through `VanillaTerrain`, so it covers the whole path from
`end.json` to the gate instead of just the JSON read.
With the setting read as a hardcoded false (the pre-change behaviour, where only
`Dim::End` decided) it fails as
`assertion left == right failed: disable_mob_generation of minecraft:the_end —
left: false, right: true`.
`NoiseBasedChunkGenerator.spawnOriginalMobs` reads
`NoiseGeneratorSettings.disableMobGeneration` and places nothing when it is
set. The shipped presets are explicit about it: `end` sets it true, the other
six set it false. Horizon never read the field and instead skipped the pass for
`Dim::End` alone, so a datapack dimension that used the End's noise settings -
or any preset asking for no creature packs - still got them, and the reason the
End was empty lived in a dimension check rather than in the data.
The setting now reaches the client seam: `Generator`'s settings carry it, the
pipeline trait exposes it next to `sea_level`, `VanillaTerrain` answers it, and
`spawn_generation_creatures` returns before doing any work when it is set. The
existing `Dim::End` check stays as well, so a preset that fails to load cannot
start filling the End; for the shipped data the two agree, since `end.json` is
the only preset that sets the flag.

anvil_update fires where AnvilMenu.createResult ends, once vanilla has
worked out the result, while the left slot holds an item: on the host for
each player's menu (single player's server thread, a LAN or dedicated
host), before prepare_anvil, and in the window's own menu. A mod is told
the inputs, the rename box's text and vanilla's result. It may change the
output, the level cost and the material cost, or cancel, which leaves no
result (NeoForge's CommonHooks.onAnvilUpdate).
The host asks again after a rename that leaves the result as it was, as
setItemName runs createResult. The window's click prediction starts from
the station's cost and material cost, so a result a mod made can be taken
there as on the server. The window names the player as the server knows
them.

Part of #9996.
NoiseBasedAquifer::compute_substance is 4.7% of the overworld's proto
phase by itself. A sixth of that went to rebuilding the 12 grid cells
around a block whenever its aquifer cell changed: every location was
unpacked again from its packed long, and the neighbourhood was copied
as a 288-byte Option. The fill walks each column from the top down, so
a rebuild usually follows the cell just above.
Each drawn location is now also kept as the coordinates BlockPos.getX,
getY and getZ read back from it, and the 12 cells are arrays of grid
index, coordinates and horizontal distance to the column. One cell
down, the 8 cells at the old anchor's y and the y below move up two
slots and only the 4 new ones are loaded, in vanilla's loop order. A
cached fluid status is read inline; computing a missing one is out of
line. Default air, water and lava are classified by their IDs before
any block name is read.
Every block, pending fluid update, error and cached cell is the same as
before: the same operations in the same order, the same positional
random draws for the same cells. A test runs the previous search
against the new one over whole columns, scrambled blocks and positions
outside the grid, and the snapshots match byte for byte.
A first draft by DeepSeek V4.1 Flash, via pi, was reviewed and
reworked.

The ledger named the four renderer overrides but not the method they override;
it now says the box is the frame's, grown by 0.5, and points at the dropped
item's own copy of it.
An item sliding from x = 0 to 1 in camera space: the box is -0.625..0.625 at the
start of the frame, -0.125..1.125 halfway through and 0.375..1.625 at its end,
where the old code had the last on every frame. A falling item's box floor is
65.0 halfway down a 66 -> 65 drop instead of the tick's 64.5.
EntityRenderer.shouldRender tests the frustum against
getBoundingBoxForCulling(entity, partialTick), which EntityRenderer leaves as
Entity.getInterpolatedBoundingBox(partialTick) - ItemEntity overrides neither -
grown by 0.5 all round.
The dropped-item pass built that box from the tick's own position, so for the
frames of a tick in which an item crossed the frustum edge it was culled at the
cell it was about to reach: an item sliding from x = 0 to 1 had its box at
0.375..1.625 (camera space) on every frame, where at the start of the frame it
stands at -0.625..0.625.
dropped_item_cull_box(previous, position, alpha, camera) is that box now, the
interpolated position grown by the item's 0.125 half-width and 0.5, with the
0.25 height below and 0.75 above.
🤖 Agent: merging the in-game mod browser. The point to check is that install never trusts the download: each file goes through horizon_mods::index::check_file (size, SHA-256, signature, manifest against the index) before it reaches horizon-mods/, and revoked files are refused. Tests pin both cases with a real .hmod.
The Wardrobe's picture (horizon_cosmetics::preview, its live view
included) draws a companion at its anchor, an aura see-through at the
feet and a trail as a short run of particles behind; the Wardrobe gets a
row for each slot.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
A companion is posed on no bone: it follows its anchor with its lag,
keeps clear of the head and, for the player's own in first person, out of
the middle of the view. Trails spawn by distance walked and are drawn as
camera-facing particles; auras blend at the feet with their back faces
dropped. Trails and auras of every player go in one see-through span after
the players. Others' follow "Other players' cosmetics" and "Hide other
players' trails and auras". Nothing is an entity or reaches a server.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
The setting that was "Show other players' auras and trails" (off, for
items that didn't exist) becomes a hide switch, off by default: others'
trails and auras show like their other cosmetics unless the player hides
them. In the game's Horizon settings and the launcher's Wardrobe, the same
cosmeticsHideFx line of horizon-extras.txt; the old cosmeticsAuras line is
dropped on save.

follow.rs: a frame-rate independent lag toward the anchor, a snap after a

Three new slots that ride no bone: a companion floats beside the player,
a trail leaves particles where they walk, an aura glows faintly at their

item.rs reads them, refuses a bone on them and measures their extent.
Nothing draws them yet.

A mob walking 0.9 -> 1.1 (eye 1.62) reads the cell at 0 at the start of the frame
and 1 from the boundary on, where the old probe read the tick's cell 1 on every
frame; a falling one reads 71.62 then 70.62. An arrow falling 64 -> 65 reads
64.13, 64.63 and 65.0, so the cell at 65 only at the end of the frame, where the
old probe read 65.0 throughout.
EntityRenderer.getPackedLightCoords takes BlockPos.containing of
Entity.getLightProbePosition(partialTick), and Entity leaves that method as
getEyePosition: getEyeHeight() over getPosition(partialTick), which is
Mth.lerp(partialTick, xo, x) on each axis.
The mob pass probed floor(position) with position.y + eye_height(), and the
projectile pass the same on its own position: the tick's own position, so a mob
walking from x = 0.9 to 1.1 was drawn lit by the cell at 1 for every frame of the
tick, and a falling one by the cell it was about to reach, instead of the cell it
was drawn in.
Mob::light_probe(partial) and Projectile::light_probe_y(partial) now give the
probe of the frame, through mobs::living::eye_probe_cell (Mth.lerp plus the eye
height, floored per axis).
Old/new for a mob walking 0.9 -> 1.1 (eye 1.62): cell x = 1 on every frame before,
x = 0 at alpha 0 and 1 from the boundary on. For an arrow falling 64 -> 65: 65.0
before, 64.13 at alpha 0 and 64.63 at alpha 0.5, the cell at 65 only at alpha 1.
Held mappings are named by an Action rather than read by key, per device, and more actions can be bound: hotbar
slots, fullscreen, toolbars, social and quick actions. Held drop repeats and throws the stack. Readers of the
movement keys see the left stick, and a bumper steps the hotbar through the wheel's gates. Prompts over gameplay
are pad-driven and keep what's behind them, the keyboard opens on every field, and focus follows its widget.
Buttons and the crosshair draw from Horizon's own art, one file per pad family, instead of text labels.

🤖 Agent: merging. The screenshot tiles, viewer and background no longer go through GPUI's never-evicted img(path) cache. Two 32k×16k screenshots on Home went from an 8.7 GiB peak to 277 MiB on the desktop. One risk to watch: the 2 s grace lets the budget overflow while more than 256 MiB of tiles is on screen at once (about 280 tiles with Show all), which is bounded by the list itself.
Screenshot tiles (Overview's three newest, the Screenshots tab), the
viewer and Home's background went through gpui::img(path): GPUI decodes
the whole picture and keeps it, and its sprite-atlas copy, until the
launcher quits. One 32768x16384 screenshot is 2 GiB decoded; with two
of them Home alone reached 8.7 GiB (24 GiB reported on Linux).
- pictures (lib): PNGs are read a row at a time and box-filtered down to
the drawn size, never held whole; other formats decode whole only
under 256 MiB. Lru keeps made pictures under a byte budget, sparing
those drawn in the last 2 s.
- picture_cache: makes them off the UI thread (3 at once), 640 px for
tiles, 3840 px for the viewer and background, 256 MiB budget; evicted
images are dropped from the window's sprite atlas.
- glass_shot_blur's blurred copies go through it too, from a shrunk read
instead of image::open.

The row said the probe was drawing-only and skipped; it is what selects the block
an armour stand is drawn with, so it now points at the code that walks it.
Four cases over the jar's values: a full stand's eye at 65.7775 (cell 65, where
the old base + 0.5 read 64), a small stand at 64.2 (65.1875, cell 65, where the
old read 64), a marker's box scanned for a 15 at (0, 65, 0) and falling back to
the first cell walked (0, 64, 0), y walked before z, the cell above the box left
out, and the marker branch ignoring the partial tick; and a burning stand's block
light at 15 with the sky light left as the probe cell's.
EntityRenderer.getPackedLightCoords reads the block Entity.getLightProbePosition
is in, and ArmorStand overrides that method:
- a marker walks BlockPos.betweenClosed of getDimensionsMarker(false) - the box it
would have without the marker flag, 0.5 by 1.975, or 0.25 by 0.9875 when small -
from position() with no partial tick, and returns the first cell whose
max(block, sky) brightness is 15, else the brightest, ties going to the first
cell BlockPos walks (x fastest, then y, then z);
- every other stand is Entity.getLightProbePosition, the eye: eyeHeight 1.7775 for
a full stand and 0.9875 for a small one (BABY_DIMENSIONS), at the frame's
interpolated position.
Horizon read floor(base + 0.5) for every stand, so a stand standing on a lit floor
in a dark room was drawn with the floor's light: a full stand on y = 64 read the
cell at 64 where its eye at 65.7775 is in the cell at 65, and a hologram marker on
a dark ceiling was lit from its feet's block instead of the brightest cell of the
box it would have without its flag.
EntityRenderer.getBlockLightLevel also puts a stand that isOnFire at 15 block
light, which was not read at all.
On a smoke server (2 ms ticks) the overhead line charged the chunk pump's spans of the
wait between ticks (1,788 a tick) to MSPT. Only the spans the tick records count now,
and a dedicated server records spans anyway for its slow-tick line (HORIZON_SPIKES,
on by default), so they are listed apart and left out of the report's own cost.
The 'other' worker jobs ran at 278k/s for 0.0 ms each: two thread-CPU clock reads
each cost more than the job; they are counted only. A sum of no players' rates no
longer reads -0.0.

`CreativeModeInventoryScreen.selectTab` shows and focuses the search box only
on the search tab; any other tab hides it, lets it lose the focus and clears
its query. Horizon focused the box when the search tab was selected but never
took the focus away, so the box stayed focused behind every other tab.
`Creative::select` now sets the focus from the tab it shows, keeping the blink
reset the search tab always had.
🤖 Agent: the Wardrobe button opens the launcher's Shop tab now, so its label drops "on playhorizon.dev"; the key is renamed in place in all 86 tables (no stale key left), and the i18n test passes.

({horizon, code}) in index.json. The browser's fit line now says
"Doesn't build on the Horizon you play (CODE): a build leaves it out until
its author updates it" when that Horizon is the one the mod would build on.
- horizon-mods index: `Version.broken_on` (empty and absent by default).
- native_fit: `Fit::Broken { code }` for a hook mod, or a mod pinned to the
played commit, when an entry names that commit.

Fixes#10067
The ItemEntityRenderer row names where its light comes from now, and
EntityRenderer.getBlockLightLevel's note covers dropped items beside mobs and
projectiles.
The three cases quote the old values: the failing probe cell of a falling item
(64 against the eye's 65), the tick's own position against the frame's halfway
one (64.7125 rather than the destination 65.2125), and a burning item's block
light (15 over a dark cell's 0, sky untouched).
EntityType.ITEM declares eyeHeight(0.2125), and EntityRenderer.getPackedLightCoords
reads the block of Entity.getLightProbePosition, which Entity leaves as
getEyePosition: the item's position plus that eye height, at the position the frame
draws (getPosition(partialTick)), not this tick's own.
The dropped-item pass probed the cell of base + 0.1 at the tick's position, so a
falling item at y = 64.85 was lit by the cell at 64 (the floor's light) while its
eye at 65.0625 sits in the cell at 65, and the light jumped a frame early when an
item crossed a cell boundary.
EntityRenderer.getBlockLightLevel is isOnFire ? 15 : the level's block light, so a
burning item is now drawn at full block light with the level's sky light; the
item's fire ticks already clear for a fire-immune stack, which ItemEntity.fireImmune
makes never on fire.
A picked-up item's particle is not an entity and keeps the cell it is drawn in.
Background automatic registry updates and manual mod operations (install,
remove, enable, disable) could mutate the same game home folder concurrently.
Because auto-update loads `mod-browser.json` before downloading and saves upon
completion, a manual install or removal occurring during the download would
be overwritten by the stale snapshot upon completion, losing manually added
mods or reviving removed mods. In addition, temporary save files could collide.
Introduce a per-game-home re-entrant mutex (`browser::lock::lock_home`)
covering mod mutation critical sections across background auto-updates and
manual operations. Use unique atomic temporary file paths during save to
prevent collision.

One mod that horizon-mixins refuses or that doesn't compile used to fail the
whole native build (#horizon-support 2026-11-05: eatinganimation's moved
target, hitbox_plus's support module, worldedit's moved chat.rs). The build
now leaves that mod out, with the mods that need it, and builds again:
- isolate.rs names the mod a horizon-mixins diagnostic is about (mod_id, its
manifest, its support module's name or destination), or the mods the
compiler's errors were traced to, and adds their dependents.
- A refusal costs one horizon-mixins run; a compile failure one compile, at
most 3 times. A server engine export still fails as before.
- native-mods.json records `left_out`, so the same mods turned on read as up
to date, and the Mods page says "X was left out: made for another Horizon
version / clashes with Y / it needs Z, which was left out" (86 languages).

The fixture registry takes a pack version so the test can install
cozy 1.0.0, turn coords_hud off as the Mods page does, and install
cozy 1.1.0: the file is updated and the mod is still off. Turned back
on, 1.2.0 keeps it on. With the old unconditional set_enabled(m.on)
the update re-enables it and the test fails at 'the update kept it
off'.
install_version_in() applied java::set_enabled(home, id, m.on) for
every mod of the pack on every install, and installing a registry pack
again is how it updates. horizon-mods.txt is the same list the Mods
page toggles, so a mod the player turned on or off in a pack profile
was reset to the pack author's 'on' by the next pack update.
The install now reads the pack's previous record (pack.json's 'id
version' entries) and carries each listed mod's current on/off choice
through the install, which turns a mod on as an explicit install. A
mod the new pack version adds takes the pack's own 'on', and a fresh
install has no previous record so every mod does, as before. The Java
mod path already keeps '.disabled' through updates the same way.

break_speed fires at the end of Player.getDestroySpeed, on the Game that

BlockBehaviour.getDestroyProgress then divides it by the hardness.
tick_mining now takes its progress from destroy_progress, like the other
digs, so the speed is worked out in one place. The remote client asks it
for blocks of hardness 0 too, so a mod's speed of 0 stops those as well.

ClimateIndex::search, vanilla's Climate.RTree search, is about 5% of
overworld proto generation (callgrind, generate_proto, seed 12345) and 2%
of the nether's. About 21 boxes are measured per search: the root's two
children and the 19 below.
Three changes, none of which changes which leaf a search returns:
- The best leaf's distance goes down into each subtree and back up with
its result. Vanilla measures the best leaf again at the start of every
subtree and after it returns; the values are the same.
- The offset axis is always 0 in the target, so each box's squared
offset distance is stored once instead of measured every time.
- When every bound in the tree and every target value is within 2^29,
no term or sum of a distance can overflow, so a partial sum only grows.
A box's sum then stops once it reaches the best distance so far: the
search would only compare it with that distance and skip the box. The
axes are added depth first, as surface biomes are points in depth.
Otherwise the full wrapping sum is used as before.
The search still walks the same children in the same order from the
same previous leaf, and replaces the best only on a strictly smaller
distance, so ties go the same way. New tests compare it with a copy of
the old search over long target sequences that keep the previous
result, on the vanilla overworld and nether lists and on generated
lists full of ties, inverted spans, extremes and values at the bound.

When entering borderless fullscreen on Windows while the window is
maximized, winit's WM_NCCALCSIZE handler forces the client area to
match the desktop work area (rcWork), which excludes the taskbar.
Because the window is sized to monitor dimensions, this clamps the
bottom edge above the taskbar and shifts the top edge offscreen by the
taskbar height (~48px), leaving the taskbar visible on ultrawide and
standard displays (upstream MC-311683).
Ensure that any transition to fullscreen unmaximizes the window first,
and explicitly pass the active monitor handle to Borderless mode so
the window covers the entire display area without vertical offset.

MultiPlayerGameMode.handleContainerInput puts the changed slots into a new fastutil
Int2ObjectOpenHashMap and ServerboundContainerClickPacket writes them as it iterates: the key 0
first, then the table from its last position down. Horizon listed them in slot order. The wire
stream harness's inventory scenario caught it: a shift-click from slot 37 into slot 10 went out
37, 10 from vanilla and 10, 37 from Horizon, a byte-level difference any server can see.

🤖 Agent: emotes, part 3 (#10069): others see your emote through the cosmetics service, now based on main. CI verify is green. Polling is bounded: at most once a second, only while Horizon players are in view, and only with Other players' cosmetics on Shown. Sending is signed and only while Show me as Horizon is on. Without horizon-cosmetics#14 deployed, the service answers 404 and the game backs off.
🤖 Agent: emotes, part 2 (#10069): the wheel and playback, retargeted to main after #10091. CI verify is green. Two clients played every emote in game; captures are in the PR. Visual only, nothing sent to game servers. #10093 follows.
Install ruby 1.0.0, turn it off in the Mods page, run the automatic
update to 1.1.0: the file is replaced and the mod is still off. Turned
back on, the next update keeps it on, and an explicit install of a
disabled mod turns it on again. Without the fix the first update
re-enables it and the test fails at 'the update kept it off'.
install_version_guarded() turned every mod it installed on with
java::set_enabled(home, id, true), and the automatic registry update
(browser/horizon/auto.rs update) installs through the same function.
A content mod the player had turned off in the Mods page therefore came
back on after every automatic update: 'off' is the absence of the
'mod.<id>:true' line in horizon-mods.txt, which the update re-added.
The guarded install no longer touches the flag. The player's own
install (install_version, which the browser and modpack paths use)
turns the mod on after the guarded install, as before, while the
automatic update leaves the mod's current on/off choice alone. A new
install still starts on because it goes through install_version.
`Creative::search_tab` and `select` as `Game::key_pressed` uses them: the
search tab is found by its type, selecting it focuses the search box, and the
query the previous tab left is emptied.
`CreativeModeInventoryScreen.keyPressed` takes the chat key on a tab that is
not the search as "show the search tab": it selects
`CreativeModeTabs.searchTab()` and sets `ignoreTextInput` so the letter the key
carries never reaches the search box. Horizon had neither: T on a creative tab
did nothing, and the letter went nowhere.
`Creative::search_tab` finds the search tab by its type, so the key selects it
through the same path a tab click uses (`select_creative_tab`, which clears the
quick-craft clicks as `selectTab` does). `Game::key_pressed` takes the chat key
there, and the `ignoreTextInput` flag it sets makes `type_chars_into_screen`
(`charTyped`) drop that one letter and no other.
🤖 Agent: emote format, the bottom of the emotes stack (#10069). pr_ready on the whole stack is green except the NixOS-only uname test. pose_body copies the target at full weight: 0.26–1.1 µs per emoting player and frame, measured. #10092 follows once this lands.

The official SMP is mob-bound (5,400 mobs, 73 ms a tick at 60 players) but the report
only said tick_creature_entities took the time, not which mobs. Format 2 adds, without
a restart and at a measured cost:
- mob_costs: one tick in four times every mob's tick and sums it by dimension and type
(ms a tick, mobs ticked, us a mob);
- level_* spans: each dimension's share of the server tick;
- chunk_workers: streaming::job_stats while recording (load/generate/decorate/light...);
- network: wire bytes in/out per player and in all (connection counters, no new
per-packet cost);
- overhead: spans and mob samples a tick at their price measured on the machine;
- horizon-report stop / status.

`ServerLevel.setChunkForced` calls `getChunk` when a chunk becomes forced, so a
command right after `/forceload add` finds it loaded. Horizon only queued it, so
`execute in minecraft:the_nether run function` with `forceload add`, `place
jigsaw` failed with "That position is not loaded" and a skyblock pack's nether
island never appeared.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
A data pack's `data/<ns>/structure/*.nbt` were ignored. A jigsaw pool naming one
placed nothing, so `/place jigsaw` failed with "Failed to generate jigsaw" and
`/place template` said the template does not exist; that is how a skyblock pack
places its island. Packs also could not replace vanilla's templates.
The enabled packs' templates now join the worldgen overrides, highest pack first,
over the prepared ones, as `StructureTemplateManager` reads resources. `/place
template` and structure blocks look in the world's `generated` folder, the packs,
then the game's own.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
`LevelAccess::load_block_entity` decoded a template's block entity, and that
drops `LootTable`, so a chest placed by `/place template`, `/place jigsaw` or a
structure block came out empty. A skyblock pack's starter chest has its items in
a loot table. Report the table as a level event and hand it to `take_loot_table`,
as `/setblock` and `/data` do (`RandomizableContainer.tryLoadLootTable`).

26.3 reads a direct block state provider as a state object. A bare string names
a provider in the `worldgen/block_state_provider` registry, so an upgraded

own features write `{"id": "minecraft:clay"}`.

Void packs turn off vanilla's iceberg noises with
`{"firstOctave": -1000, "amplitudes": []}`. The upgrader left this as it was and
called it "more than 32 octaves or negative amplitudes"; 26.3 cannot read it, so
the world failed to start with `invalid world generation field: base_octave`.
With no octaves the noise is 0 everywhere, which 26.3 writes as one muted octave:
`{"base_octave": 0, "amplitude_modifiers": [0.0]}`.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
`state()` in the generator read only `{"Name", "Properties"}`, or the id alone,
so noise settings with `{"id", "properties"}` failed the world start with
`invalid generator resources: block state`. That is the form 26.3 uses and the
one `horizon-port-pack upgrade-datapack` writes for any non-default state. Decode
these two fields with `BlockStateJsonCodec`, as the rest of worldgen does.

A run's state ids count every change its server made since the login, so a click numbered 53 in one

GameRenderer.pick aims along Entity.calculateViewVector: float radians through Mth.sin and Mth.cos,
the 65536-entry table. Horizon aimed with exact double trigonometry, which moved the hit point a
placement sends (ServerboundUseItemOnPacket's cursor) and an interaction's point by up to ~1e-4 of a
block. The wire stream harness's bridge scenario showed it: same position and look, cursor z
0.7173712 from vanilla, 0.7173119 from Horizon. Anticheats that recompute the cursor from the ray
compare it to vanilla's arithmetic. The other view_vector callers (projectiles, dragon, boats...)
are left for their own checks.

`Block.pushEntitiesUp` runs when these blocks gain the collision they add on
top. The farmland/path to-dirt path already emits the `push_entities_up` block

new block.
🤖 Agent: Fixed to the 26.3 jar's DTOs: the region preference travels as its id (0/1/2) and the region as its nameId, so a Realm that has a preference parses again (it used to fail the whole RealmServer parse). preferredRegions reads regionDataList/regionName, and the configuration POST puts the slot under options with update_slot's RealmsSlotUpdateDto. New tests pin the POST body and the parsing; CI verify is green on this head.

From review, against vanilla (getAttackBoundingBox and getHitbox read the
current getVehicle()):
- A mob vehicle's box comes from the mob snapshot, which holds it as it is
after its own tick this tick, not from the last positionRider.
- The seat positionRider records names its vehicle, and is used only while
the mob rides that one: a dismount or a new vehicle no longer reads an old
vehicle's box or attachment.

🤖 Agent: wear() still fires the durability trigger after Unbreaking, and the broken stat now comes before the rod. The parity failure at ~17:00 was the playhorizon runner's dead .horizon-prepare.lock link, not this change: rerun on this head.

The parity failure at ~17:00 was the playhorizon runner's dead .horizon-prepare.lock link, not this change: rerun on this head.
🤖 Agent: Same two calls finish_consuming makes, before the stack shrinks, as Consumable.onConsume orders them. drink_ominous_bottle awarded neither, so nothing counts twice. The parity failure at ~17:00 was the playhorizon runner's dead .horizon-prepare.lock link, not this change: rerun on this head.
🤖 Agent: The pack-less structure tags are a OnceLock keyed on the first resource root, as StructureSpawns::shared is. location_structure_tags_hold_their_structures passes with prepared resources.

🤖 Agent: On playhorizon (vscreen, lavapipe) every_screen_has_targets, pause_icon, erase_checkbox, controller_settings_pad and settings pass. The empty-label target can add a second target on a rect that already called target_as: drawn_targets dedups only against labelled widgets, not between targets. Nothing on main seems to do that today. Union run on playhorizon (main a1e0c0db0 + this gate's 11 PRs): fmt, clippy, all touched crates' tests pass.
The Wardrobe's still picture becomes a live view of the player's own skin
(both layers, slim or wide arms) wearing their items, drawn by the same CPU
renderer (horizon_cosmetics::preview) only when something changed:
- drag to turn (followed past the view's edges while held), scroll to zoom
up to 3x on the head, Reset view; hovering an owned item's card tries it
on (Nothing takes the slot's off) until the pointer leaves;
- items animate (swing, bob, spin) on the game's 20-tick clock with
Item::animate, as the game does, only while the window is in front and
not under reduced motion (HORIZON_LAUNCHER_MOTION=always keeps them going);
- horizon_cosmetics::viewer::Stage decides each frame: nothing changed, no
picture and no timer; at most 20 pictures a second while animating (one a
tick), 60 while dragging. Pictures are drawn at the view's size in points
(240x330, about 2 ms) and baked up to device pixels;
- preview::Camera holds the turn, tilt and zoom (with headroom above the
head for tall hats and back items), Draw::item_posed keeps items on posed
bones, and viewer::BodyMotion is the hook an emote plays through
(Viewer::play), for the emote format in flight (#10091).
The view is a GPUI view of its own, so a new picture rebuilds it alone;
the pointer is handled by the page's element around it, since GPUI Fast
hit-tests the page's own elements. "Turn" gives way to "Reset view" and a
hint, in every language.

Vanilla's Gui.setScreen calls Screen.clearFocus on the screen it leaves, so
a screen that comes back starts with no widget focused. Horizon kept the
focus a mouse click gave a button (the title's focused_button, pause_focus,
death_focus, the options' focus), so going back to the main menu redrew that
button highlighted (AbstractWidget.isHoveredOrFocused) with the pointer
somewhere else.
The front screen is now tracked with key_screen() (which the keyboard's focus
already uses for its own screen changes); when it changes, every menu drops
its click focus. The startup menu does the same for its title behind the
options, before the loading hands that title to the game.

- click-slot without a renderer clicks the menu itself (the vanilla driver's handleContainerInput); horizon-ctl's
clicks where the slot is drawn, which --headless never does.
- The reset's last teleport is the player onto itself: from the console `~` is the world spawn, which put the

MultiPlayerGameMode.ensureHasSentCarriedItem runs in attack, interact, useItem, useItemOn,
releaseUsingItem, dropItem, piercingAttack and continueDestroyBlock only. A swing at nothing,
the start of a dig or an offhand swap sends no slot: a number key pressed in that tick goes out
at the start of the next one (MultiPlayerGameMode.tick). Horizon sent the slot whenever the tick
had a click. The wire stream harness's hotbar_swap scenario caught it: a tap of 2 with a swing at
the air sent SetCarriedItem before the Punch, a tick before vanilla.

ServerPlayer.openMenu, when createMenu returns null for a spectator, sends
container.spectatorCantOpen to the action bar (red). Horizon's refusal in
spectator_open_menu and the chest-boat guest handler was silent.
🤖 Agent: merging. The layout lines only add keys to horizon-extras.txt; files without them load as before (every widget at its default place and style). Verify is green; stacked on #10077.
🤖 Agent: merging. Every widget reads local state only (no packets, no server queries); with every widget off, draw_pvp_hud returns after Hud::any(), so a player who never turns one on pays nothing. Verify is green; pr_ready --quick on playhorizon fails only the render crash:: tests that SIGSEGV under llvmpipe there, and crash.rs is untouched.
🤖 Agent: open_menu already counts the guest as an opener (container_opener_event), so the raise in lan_open_container counted them twice and stopOpen never reached 0, for chests as well as shulker boxes. The author's lan_e2e shulker_menu check pins the lid open, then shut, on both host and guest. Union on main dd675b574 green.
🤖 Agent: The server now sends one minecraft:vibration LevelParticles (count 1, no spread) with the listener's PositionSource and arrival ticks, and only draws locally when the window is the client, so a server-thread world doesn't draw it twice. Tested at a729b3cfe in a union on main dd675b574 (fmt, clippy, 4426 client tests green); this head only adds the author's main merge (test helper conflict) on top.
Mob.getAttackBoundingBox widens the attacker's box on x and z to its
vehicle's before the melee reach is added, so a zombie on a horse, a
chicken jockey or a mob in a boat reaches as far as the side of what it
rides. LivingEntity.getHitbox starts a rider's box at its seat
(vehicle.getPassengerRidingPosition(this).y), so its legs can't be hit; for
a riding player that is 0.6 above its feet (Avatar.DEFAULT_VEHICLE_ATTACHMENT).
positionRider now records each mob rider's own vehicle attachment and its
vehicle's box (mobs, boats, minecarts, primed TNT, displays), which the
melee check and the slime's touch read.

An Entry on the Servers list can name a host: its folder is then on that
computer, and Entry::command runs the same horizon-server arguments there
as `ssh HOST horizon-server --dir DIR ...`, with the system's ssh and the
player's keys (BatchMode, so no password is asked for or kept). Each
argument goes to the remote shell in single quotes, and a host that ssh
could read as an option is refused. remote::check asks the server there
for its status and says in plain words what is missing: a key, the host,
horizon-server, or a server in that folder.
Lists written before keep reading as they were; nothing on the page uses
remote entries yet.

Vanilla reads network NBT with NbtAccounter's 2 MiB quota, which
charges each tag an estimate of its heap size: at least 8 bytes (EndTag,
the smallest; a byte tag in a list costs 13). Horizon counted only the
bytes read, plus up to 1,000,000 nodes, so a crafted server could send a
1 MB list of byte tags that vanilla refuses and have Horizon build ~1 M
32-byte Tags from it, about 16 times the memory.
- buf::Reader::nbt caps a network NBT value at NBT_QUOTA / 8 = 262,144
tags (NBT_MAX_TAGS). Every value vanilla accepts has at most that
many, so nothing vanilla accepts is refused, and one value's tags now
take at most ~8 MiB here.
- custom::validate checks component values with the same reader, so it
follows.
- Test: a list of 262,143 byte tags (with its root, 262,144) reads; one
more is refused although it is a few hundred KB.
A full port of NbtAccounter's per-type charges would be closer still;
this bound needs only its smallest charge, so it can't refuse what
vanilla takes.

tab_list::visible with the HUD hidden answers false for a held key with two
listed players and for a local server with a list objective, and the
scoreboard's LAN test asserts the same through the game's call.
Hud.extractRenderState calls extractTabList inside `if (!isHidden)`, so with
the HUD hidden (F1) the player list does not draw at all, whatever the
player-list key or the list objective says.
Horizon's hud_layers only skipped the tab list under F1 when the chat screen
was open: with no screen, holding Tab drew the list over the hidden HUD. The
gate is now in tab_list::visible, next to the key and the local-server rules
it already applied, so every caller gets it.
After a refused login the connection stayed open, so within the 30 s
login window a client could send as many AUTH packets as it liked: with
the 16 connections allowed at once, thousands of guesses a second
against an RCON port on 0.0.0.0, each adding a supervisor log line.
Vanilla does the same, but this module already departs from vanilla for
safety (constant-time comparison, login deadline, client cap), and this
belongs with those.
- A refused login (wrong or empty password) answers as before, waits
REFUSED_PAUSE (1 s) and closes the connection. Its place stays taken
meanwhile, so the client cap also bounds how fast passwords can be
tried: at most 16 guesses a second instead of thousands.
- A command before the login is still refused without closing, and the
wire protocol is unchanged; standard RCON clients connect again after
a refusal.
- Tests: a wrong and an empty password each end their connection after
the pause; a failed login after a successful one does too. The pause
is a Limits field so tests use 200 ms.

The server runs two async workers and keeps SQLite on tokio's blocking
pool (lib.rs, `blocking`), but /hub/vote, /hub/votes and /hub/report and
the token-protected /v1/export/* still called app.store() on the
workers. While a blocking-pool task holds the store mutex (a large batch,
the daily upkeep), two votes or reports from different addresses park
both workers on it and every handler stops answering, /healthz
included; per-address limits don't help, it takes two requests.
/hub/votes also held votes_cache's lock while waiting for the store.
- hub::vote and hub::votes run their store calls through blocking();
votes reads the cache, releases its lock, counts on the blocking pool
and stores the result after.
- intake::receive checks the day's count and queues the report in one
blocking() call, under one store lock as before; report marks the
issue filed through blocking().
- export::benchmarks and export::hardware read through blocking().
- A failed blocking task answers 503 "try again later" through each
module's own refusal (the hub's keeps its CORS headers).
Behaviour is unchanged otherwise: the crate's 58 tests pass as they are.

Part of #9996.
The terrain noise (old_blended_noise) is a lerp between two 16-octave
smeared Perlin stacks. Lerp reads its first branch only where alpha is
not 1 and its second only where alpha is not 0, and in the overworld
about 37% of the coarse points have alpha 1 and 50% alpha 0. The lerp
now passes each branch a bit per Y of each column it reads, and a noise
volume skips the others (DensitySampler::sample_needed,
Noise::add_to_needed; samplers without it still sample everything).
When a column's Y cells change at every Y, as in the stacks'
high-frequency octaves, four Ys in four cells now go through the same
vectorized lane code as four Ys in one cell, each lane with its own
cell's corner terms. Gradient lookups are a loop rather than
array::map, which LLVM had left out of line.
Every value is computed by the same operations in the same order:
snapshots match byte for byte and the tests compare against the
unbatched, unmasked loops.

horizon-port-pack read jar entries with read_to_string/read_to_end and
no limit. zip stops an entry only at the size it declares, which can be
4 GiB (more with zip64), and the launcher runs check::check in its own
process on every Java mod a mod-browser search lists, without a click.
So one published mod with a highly compressible mods.toml could abort
the launcher of everyone whose search showed it. A 522 KB jar whose
mods.toml inflates to 512 MiB made `horizon-port-pack check` reach
594 MiB and abort; with this change it peaks at 9 MiB and refuses the
jar.
- crate::entry: read()/read_text() with a per-entry cap, and a Budget
for a running total over one pass of an archive, so many entries
under their cap can't add up either. Limits: 16 MiB per text entry
(JSON, TOML, the manifest), 64 MiB per file kept as it is, 1 GiB per
archive pass. Only bytes actually read count; an entry declaring more
than what is left is refused unread.
- Every zip read in the crate goes through it: jar::read's metadata
(a too-large file refuses the jar), carry's namespace scan and file
copy, worldgen's piece counts, structure-set and biome tags,
processors, upgrade::read_pack and import's JSON index. check.rs kept
its 16 MiB per-class cap and now also refuses a jar whose classes
together unpack to more than 1 GiB (a thousand entries just under the
per-class cap was the same attack).
- Tests: the cap and the running total (declared or not, refused
entries counting), UTF-8, and check() refusing a small jar whose
mods.toml unpacks past 16 MiB.
No parity change: real mod files are far under these limits.

- Mine: while an emote plays, the game tells the cosmetics service, signed in as for "Show me
as Horizon" and only while that is on: `POST /v1/emote`, with a session kept an hour
(`account::Kept`). A loop is said again every 30 s.
- Theirs: `horizon_cosmetics::Feed`, a thread, asks `POST /v1/emotes` which Horizon players in
view play one, at most once a second and only while some are in view, then fetches the item
files once. On failure it waits 15 s, doubling up to 10 min. Their models play the emote from
where it is; a player who moves ends theirs at once.
- Follows "Other players' cosmetics": with anything but Shown, nothing is asked and nothing is
drawn.
- The wheel: the account's emotes (`GET /v1/me`'s `emotes`), read when it opens, at most every
10 minutes.
Nothing reaches game servers; vanilla clients see nothing.

The mod page opened the project named by HORIZON_LAUNCHER_PROJECT (a
screenshot aid) and then called std::env::remove_var so it wouldn't open
again. By then the download, check and keyring threads are running, and
remove_var races getenv on any of them (glibc's DNS resolution
included): unsound, which is why edition 2024 makes it `unsafe`. The
launcher is on 2021, so it compiled silently.
- A static flag remembers that the page was opened this run; the
environment is no longer written. Same behaviour: the page opens once,
after the first search that finds it.

A busy server ran hit_target's reset teleport on the scenario's first tick: the vanilla client's first move

- The wheel: Emote Wheel (`key.emote`, B by default, unbound on a controller; rebindable in
Controls) shows up to 8 emotes around the middle of the screen. To play one: hold the key and
release on an emote, click one, or press its number.
- The emote cancels (and fades out) on movement, an attack, mining, using an item, being hurt,
riding, sleeping, gliding or sneaking. Only a standing player starts one.
- From first person, the camera turns to the front view and eases out from close for the emote,
then comes back.
- Bones: `anim::setup` lays the emote over vanilla's animation, keyed bones only.
- Props: drawn with the cosmetics, growing in and out with the blend.
- `horizon-ctl emote [ID|stop]`.

one (the art and the bench).

The server built its world tables from the content root only when the
world had data packs; without one it kept the tables loaded at startup,
so a switched mod's recipes and tags never applied (seen in game:
/recipe give still said Unknown recipe). After a live switch the tables
are built from the new root. An install that waits for a restart says so
on the project page.

An item of the new `emote` slot carries an `emote` block: per-part tracks of keys (rotation,
offset, a prop's scale) eased smooth (Catmull-Rom), linear, in_out or step, one-shot or looping,
faded in and out over `blend` ticks. `Item::parse` checks its limits (200 ticks, 16 tracks,
32 keys a track and 192 in all, 360° turns and 8 px moves, the root 720° and 16 px, props'
reach through every key). `Emote::pose_body` poses the six bones (keys replace a bone's
rotation, keyed bones only), `pose_props` the props, and `Playing` gives an emote's time and
weight, its cancel included. Visual only, nothing random.

`screen_draw::paint`: an inner scissor draws to the overlap of both, a scissor
with nothing around it is cut to the screen, and one that misses the outer
clip draws nothing while the outer clip takes over again when the inner closes.
`GuiGraphicsExtractor.ScissorStack` pushes each clip intersected with the one
around it (the screen while there is none, `ScreenRectangle.empty()` when they
miss) and pops it back when it closes. `screen_draw::paint` kept a single clip
that each `Draw::Scissor` replaced: a nested scissor stopped the outer clip
applying at all, and the outer one never came back after the inner closed.
`paint` now keeps the stack: `Draw::Scissor` pushes the intersection with the
enclosing clip (or the screen) and `Draw::NoScissor` clips what was drawn since
and pops back to the enclosing clip. `intersect` is `ScreenRectangle.intersection`.
`RegionFileVersion.configure` was the row that named this gap: read from
server.properties and never applied. `Compression::configure` now applies it
from the dedicated server's startup and `compress_records` asks
`Compression::selected()`, so the row says `port` with what each half does.
NautilusAi.findNearestValidAttackTarget picks the closest #nautilus_hostiles
in water from NEAREST_VISIBLE_LIVING_ENTITIES, the sensor's list of what the
nautilus can see; Horizon took any pufferfish within 16 blocks, through
walls. Its cooldown and 1 in 2 are drawn from the level's random
(level.getRandom()), not the nautilus's own.
Armadillo.actuallyHurt panics (rolls out) on #panic_environmental_causes,
which also holds freeze and sulfur_cube_hot; Horizon listed the other six.

Two cases, one per half of the port:
- `compression::tests::the_selected_region_version_follows_the_property` walks
the four names `RegionFileVersion` registers (`gzip`, `deflate`, `none`,
`lz4`) against `Compression::selected()`, checks the default before any is
set is `deflate`, and checks that `zstd` and the wrong case `LZ4` are refused
and leave the selection alone, as vanilla logs the value and keeps the one it
had.
- `save::tests::a_chunk_is_written_with_the_selected_region_version` runs the
function the save path calls, `compress_records`, once per name, and asserts
the record's codec is the selected one and that its bytes decode back to the
same chunk.
With `compress_records` back on `Compression::Zlib` the second test fails with
`left: Zlib, right: None` ("written with none") and would then fail on `lz4`
with `left: Zlib, right: Lz4`.
Also here: the helper-parity test next door now dates its expected records with
`Compression::selected()` rather than `Zlib`, so it keeps checking that the
helpers agree with one thread whatever version the process selected instead of
pinning the default.
Vanilla's `Main.main` hands `server.properties`' `region-file-compression` to
`RegionFileVersion.configure` right after the settings are saved, and every
`RegionFile` written afterwards uses the version it selected (`getSelected`):
`gzip`, `deflate` (the default), `none` or `lz4`. Horizon parsed the key into
`ServerProperties.region_file_compression` and nothing read it, so every chunk
region was written as `Compression::Zlib` whatever a server asked for.
`Compression::configure(name)` and `Compression::selected()` are the two halves
of `RegionFileVersion` over the same kind of process-wide selection, starting at
`VERSION_DEFLATE`, with `REGION_FILE_NAMES` in the registration order vanilla's
error message lists. A name is matched exactly, as `VERSIONS_BY_NAME` does; an
unknown one changes nothing and says so. The dedicated server's startup calls it
where vanilla does, before the EULA check, and logs vanilla's line for a value
the table does not know. `save.rs::compress_records` encodes each record with
the selection, so the chunks the save path writes carry it; the read side needs
no change, as `Compression` already decoded all four and the header's version
byte names each chunk's codec.
focus_on looked a widget up before stepping, so a row scrolled out of view
ended the case: it now steps until the row is drawn. optimize_world's job
finished before the case could look on a fast machine: 60000 linked regions
take long enough and cost almost nothing. A tiling compositor sizes the hidden
window too, which fails every case that scrolls, so the harness warns.

RegionSelectionPreference travels as its id (0, 1, 2) and the region as its nameId, so a
Realm with a preference no longer fails to parse as a String. PreferredRegionsDto reads
regionDataList / regionName / serviceQuality, RealmsConfigurationDto posts the slot under
options with update_slot's RealmsSlotUpdateDto (worldTemplateId, worldTemplateImage), a Realm
without a preference is automatic by owner (RegionSelectionPreferenceDto.DEFAULT), and the
labels use the realms.configuration.region* keys vanilla's settings tab shows.

tools/test_wire_stream_parity.py: a Horizon client and a real vanilla 26.3
client join a vanilla server through tools/net_capture.py and play the same
tick-indexed scenarios (walk, sprint-jump, strafe, w-tap, sneak, hits,
sprint combos, block-hit, rod, bow, eat, bridging, inventory, hotbar swaps,
a teleport during a dig). tools/wire_stream.py cuts each serverbound stream
into client ticks (ClientTickEnd ends one) and decodes the packets; every
tick must hold the same packets with the same fields.
Horizon plays a scenario from HORIZON_TICK_SCRIPT (game/tick_script.rs),
before each client tick; vanilla from VanillaTickScript.java, which hooks a
fixed point of Minecraft.tick (Tutorial.onLookAt) and presses the keys
through KeyMapping.

LocalPlayer.isShiftKeyDown reads input.keyPresses, which LocalPlayer.aiStep
sets from the keys: what the last ServerboundPlayerInputPacket said.
Minecraft.handleKeybinds runs before it, so a sneak pressed in the frame of
a right-click counts from the next tick. Horizon read the live Shift key for
ServerboundInteractPacket's secondary flag and for every secondary-use
check (isSecondaryUseActive): a click in that frame sent a sneaking
interaction a server saw before the sneak itself.

LocalPlayer.sendChanges sends a passenger's look, then the vehicle it
controls, and only then its sprint (sendIsSprintingIfNeeded); riding a
vehicle it doesn't control, it sends no sprint at all. AbstractBoat.tick

sendChanges. Horizon sent the sprint first and for any vehicle, and the
paddles last.

MultiPlayerGameMode.tick, first in Minecraft.tick and run with a screen
open too, sends the slot chosen since the last tick
(ensureHasSentCarriedItem); LocalPlayer.sendChanges sends no slot. Horizon
also sent it at the end of the tick that changed it, before the input and
the move: a number key pressed in a tick went out one tick early, on the
other side of the movement packet a translating proxy (ViaVersion to an
older server) turns into that tick's flying packet. An action in the same
tick still sends the slot first, as ensureHasSentCarriedItem does.

ClientPacketListener.handleMovePlayer accepts the teleport, then runs
MultiPlayerGameMode.stopDestroyBlock: a dig the teleport interrupts (an
anticheat's setback while mining or bridging, a /tp) sends
ABORT_DESTROY_BLOCK and starts the attack strength again. Horizon dropped
the dig without a word, so the server kept counting it.
BlockStatePredictionHandler lives in the ClientLevel: handleLogin (a proxy's
server switch) and handleRespawn into another dimension make a new one, so
the use and dig sequence numbers count from 0 again. Horizon counted on for
the whole connection.

A mapping bug report needs to know whether gilrs found an SDL row for a pad
and which id such a row would need. pad status now lists mapping_source
(sdl, driver or none) and uuid (32 hex digits, the id an SDL row starts with).
With splitscreen on, PadRouter holds the gilrs reader, so pad status said

81 of ATM10's mods listen to RenderLevelStageEvent to draw in the
world at a stage of the frame. Main has three hooks for that, none
labelled:
- world_submit (fragment world_canvas): quads and text right after
the particles, before the hand;
- world_primitives (fragment): lines, boxes, beams and text at the end
of the world pass, before the hand;
- world_drawn (API 58): the drawn world's colour, depth and matrices,
once the whole level is drawn.
Each gets "neoforge": "RenderLevelStageEvent (...)", with where it
draws in words, so horizon-port-pack events maps the 81 mods to them.
world_drawn also gets side client and cancellable false; the fragments
had theirs. NeoForge's user documentation doesn't cover this event,
so the labels use only its name.

The note kept 0.1 at least until 0.2 leaves experimental, which would keep
today's HDR path (marks, the 16-bit unorm frame, Smooth Gradients) alive for
0.1 packs alone. The shader API is experimental, which stability.md lets
change in any release without notice. So step 5, which turns 0.2 on by
default, also stops serving 0.1: 0.1 packs are refused with stability.md's
message, the registry lists 0.2 packs, and Golden Hour's 0.2 port becomes the
example. Later experimental lines follow the same rule. The shader API page
tells pack authors.

then the entry's holder or its ResourceKey), as it does jukebox_playable;
26.1 made them plain holders. Horizon read the flag as the holder, so a
goat horn's slot came one byte long and the entity data around it one

From review, against vanilla:
- getActiveItem().get(ATTACK_RANGE) includes the stack's patch: an added
minecraft:attack_range (the codec's defaults: max_reach 3, min_reach 0,
mob_factor 1) sets the reach, and !minecraft:attack_range takes a spear's

Mob.isWithinMeleeAttackRange takes the active item's attack_range when it
has one: the box is inflated by effectiveMaxRange (max_reach * mob_factor,
2.25 for every spear) instead of the default sqrt(2.04) - 0.6, and a target
within effectiveMinRange (min_reach * mob_factor, 1.0) is out of range.
Horizon always used the default, so a mob given a spear without a
SpearUseGoal (a vindicator, say) hit what stood right beside it and missed
what the spear reached.
New mob AI scenarios: a vindicator with a spear against a player out at the
spear's reach and right beside it, and zombies with a spear (their
SpearUseGoal; the probe now names it as vanilla does).

A client mod hears the window's player log in to a server, single
player's own included: native_client_player_network_logging_in(), at
the end of the Login arm (ClientPacketListener.handleLogin), after the
new client level. Respawns and dimension changes don't log in again.
Horizon makes the player with the server's first position, so
native_player() is None there; native_send_packet reaches the server.
client_disconnecting, which main fires before a connection is
discarded (Minecraft.disconnect), gets the catalog label
ClientPlayerNetworkEvent.LoggingOut, so horizon-port-pack events finds
it. The docs describe the pair.

in the build. Registration at start is untouched, so its content stays
registered; RenderHooks keep drawing until a restart; mixin code still
checks native_on.

A content root is built per set of mods (.horizon-cache/mod-content/<stamp>),
so a running game keeps reading the root it was given while a switch
builds another; roots unused for a day are removed. Turning a mod on or
off in Options > Mods, or installing one from Browse Mods, applies at once
when the mod has only assets and data: the client reloads its resources,
then the server reloads its data packs as /reload does and resyncs its
players. A mod that adds blocks, items, mob effects, entity or menu types
or changes world generation keeps loading at start, and the Mods page
says to restart.

Options > Mods > Browse Mods lists the registry's content mods for this
game (the index the launcher reads), searchable by name, tag and category,
with a page per project: authors, licence, categories, description and
changelog, Install or Update, its switch once installed, and its page on
the website. An install is checked as the launcher's (size, SHA-256,
signature, manifest against the index) and recorded in mod-browser.json,
so the launcher lists, updates and removes it.

What content mods can switch live (assets and data), what needs a world
reload (registries, worldgen), the in-game mod browser, and the native
fast path: every installed native mod built in and switched at run time,
with the dylib and wasm paths left to arismoko's fork.

In vanilla (\LivingEntity.tick\), a passenger's body yaw matches its vehicle's rotation
(or living body yaw), clamped to keep head yaw within [-85°, 85°], and does not update
limb swing / walk distance from vehicle motion.
Furthermore, \Minecraft.handleKeybinds\ blocks opening the inventory (\keyInventory\)
while in a portal transition (\handlePortalTransitionEffect\), preventing repeatedly
reopening the inventory screen while standing in nether portals.
- Compute ridden vehicle yaw for boats, minecarts, mobs, and cushions in \perspective.rs\.
- Align rider body yaw to vehicle rotation, clamped to [-85°, 85°] of head yaw.
- Disable walk distance accumulation when riding so the player model does not swing limbs.
- Guard \KeyCode::KeyE\ in \game.rs\ and \
emote.rs\ when in portal transition.

Enderman.teleport is LivingEntity.randomTeleport(x, y, z, true,
#enderman_does_not_teleport_to). Horizon took the first full-collision
block as the ground and landed on top of it, checked water only at the
eyes and lava only at the feet, and never looked at the tag, so endermen
teleported onto magma, into fire, sweet berry bushes and wither roses.
Now, as vanilla: the ground is the first #entities_can_teleport_to block
below the spot, and the enderman lands at the spot's height less the blocks
it went down. The ground and every block in the new box must not be in
#enderman_does_not_teleport_to, and the box must hold no liquid. The
motion is kept (Entity.teleportTo -> snapTo), both teleport sounds play at
the new spot, and GameEvent.TELEPORT goes out from the old one.
The new rain scenarios also showed when the water's hurt comes. It is the
end of LivingEntity.aiStep, after pushEntities, with or without AI, not
baseTick. Enderman.hurtServer draws its 1 in 10 teleport chance after
super.hurtServer (its hurt sound's pitch first), also when the hurt
cooldown refused the damage, and teleports at once. Horizon instead forced
a teleport in rain without the draw, one tick late.

The configuration screen's Settings tab (RealmsSettingsTab): the world's name and
description fields (the click moves the caret between them), the region preference line
and its Region Preference button, and the open/close toggle moved here from the footer
(vanilla keeps it on this tab). Leaving the tab — switching tabs or Back/Escape — saves
the changed name, description and preference through RealmsClient.updateConfiguration
(POST worlds/{id}/configuration with RealmsConfigurationDto's JSON: the active slot, its
settings, the preference and the description).
RealmsPreferredRegionSelectionScreen: the automatic choices and every manual region, a
click selects, Done writes the choice back to the tab and Cancel drops it.
RealmsClient gains getPreferredRegionSelections (GET regions/preferredRegions) and
updateConfiguration; RealmServer reads regionSelectionPreference; RegionSelectionPreferenceDto,
RegionDataDto and RealmSetting serialization join the DTOs.
The tier's render/simulation distance options and the region quality icons are the next
PRs (the icons need sprites the GUI atlas does not carry yet); the region rows say their
name for now.

A client mod hears each client tick of the window, at the top and the
end of vanilla's Minecraft.tick: native_client_tick_pre() before any of
the tick's work, native_client_tick_post() once the world's tick, the
chat queue, music and sounds are done. They fire 20 times a second on
the title screen, while paused and in a world alike, as vanilla's tick
runs, and never on a server (single player's ticks on its own thread).
The fragment labels them ClientTickEvent.Pre / .Post, client, not
cancellable.
Checked in game with horizon-ctl and a local probe mod: about 20 calls
a second of each, always paired, on the title screen, in a creative
world and under the pause menu.

The landing's raw write is applied before the game finishes it: the game
now asks the hook there, and a cancel puts the previous block back and
skips the neighbour updates and the level events. The crop above trampled
farmland stays, because breaking it is the neighbour update and not a
write of its own.
`FallEvent::Write` carries the block it replaced, so the game has
something to put back. A guest's landing is asked with that guest's UUID.
A player's landing tramples farmland into dirt and breaks turtle eggs with
no hook a server mod can cancel, so a land-claims mod cannot stop a guest
from trampling inside a claim (#9036, #9873 item 3).
`native_entity_change_block_v2` is asked with the player whose landing it
was, the position and both block names, and can cancel the change. It is
additive: `native_entity_change_block` keeps its signature and firing point.
PrimedTnt.addAdditionalSaveData stores the igniter as an `owner` UUID
(EntityReference.store) and getOwner resolves it against the level when
asked. tnt_to_nbt now writes the live owner's UUID (a guest, the host
player or a mob), and a loaded TNT looks its saved owner up when it
explodes, so the blast is credited to the player or mob that lit it after
a reload, a portal trip or a chunk unload. An owner that is not online
keeps its UUID through the raw compound.

38 entries still held their English text (the modpack coverage reasons, Performance mode, the
Vulkan fallback notice and a few command-line hints). 15 entries said tu while the other ~110
said vous, sometimes side by side on one page; they now say vous, as the game's own French
table does. Names that read the same in French (Mods, Console, Nightly, Snapshots...) stay.
`horizon-port-pack events <jar or folder>` reads class files for the
NeoForge events a mod listens to (an @SubscribeEvent method's parameter,
a method reference or lambda that takes one event) and the Capabilities
fields it reads, and looks each name up in native-hooks.json's `neoforge`
labels: a hook, another phase's hook, a hook whose label says why it
isn't quite one, or none. Over a folder of jars it ranks the names by
how many mods use them. Names NeoForge changed after 1.21.1 are looked
up under their new ones. It reads names, never code.
On ATM10's 498 jars it takes 8 s: 416 of 497 mods use 326 names, 6,616
uses in all. Main's catalog has a hook for 23% of them, and 43% with
#9924's labels. The top gameplay gaps are ClientTickEvent (95 and 46
mods), RenderLevelStageEvent (81) and ClientPlayerNetworkEvent (53, 35).

A vanilla list keeps the wheel: AbstractContainerWidget inherits
AbstractScrollArea.mouseScrolled, which scrolls and never reaches the rows, so
CycleButton.mouseScrolled only runs for a button outside a list. Horizon stepped
the row under the cursor, so scrolling a long page changed options.
"Scroll wheel changes settings" keeps that behaviour as an opt-in extra, off by
default. Its saved key is new because the old one was written as true by every
install, and its tooltip has a new key because other languages said "as in
vanilla"; they fall back to English until translated.

A scan of ATM10's 491 mods for their NeoForge event listeners (#9921)
showed nine unlabelled hooks behind events many of them use:
RegisterCommandsEvent (95 mods), ItemTooltipEvent (74), the item and
fluid block capabilities (129, 88), RenderHighlightEvent.Block (41),
ServerStartedEvent / ServerStoppedEvent (48, 41), LivingDropsEvent (36),
LivingKnockBackEvent and ExplosionEvent.Detonate. Each label comes from
the hook's own doc comment and firing point; `cancellable` matches its
mod_api contract, and block_highlight keeps the side and cancellable it
already had.

Now that the golem keeps its anger target through updatePersistentAnger:
NeutralMob.playerDied ends anger at the dying player even once the golem
lost sight of them; the save writes the anger target, not the current
target; and anger at a mob is written with that mob's UUID and read back
as anger at a mob, so a reloaded golem that was fighting a monster is not
isAngryAtAllPlayers under universal_anger. A calm mob no longer keeps a
loaded angry_at in its save.

`transmuteCopyIgnoreEmpty`: at 18 + 7 of 25 the carrot on a stick becomes
a fishing rod that kept its custom name and starts whole, where the old
path wrote a fresh plain rod. Wear that Unbreaking took away (0) breaks
nothing, and a stack with no durability never breaks.
`FoodOnAStickItem.use` wears the stick with
`ItemStack.hurtAndConvertOnBreak`, which runs `hurtAndBreak` - and
`hurtAndBreak` asks `processDurabilityChange` first, so Unbreaking has its
say before any damage lands.
`use_steering_stick` added the whole 7 (carrot on a stick) or 1 (warped
fungus on a stick) straight onto `stack.damage`, so an Unbreaking stick
lasted exactly as long as a plain one, and it never reached the mods'
item-damaged hook.
A mod tank can now refuse a fluid through native_block_entity_accepts_fluid (NeoForge's IFluidHandler.isFluidValid). The server asks it before filling a tank in both insert passes and before native_move_fluids counts a tank's room; every tank accepts every fluid unless a mod cancels. A water tank can take no create:chocolate, and a removed mod leaves no fluid id it cannot use behind.

The row pointed at the geometry and carried the missing rule as a gap;
the grid now goes through `item_tooltip::bundle_tooltip`, which asks
`TooltipDisplay::shows("minecraft:bundle_contents")` before the layout.
`BundleItem.getTooltipImage` returns nothing when the stack's
`minecraft:tooltip_display` hides `minecraft:bundle_contents`, so a
bundle given with `hide_tooltip` or with that component hidden drew no
grid. Horizon drew the grid for every bundle, and the tooltip box grew to
hold it.
`item_tooltip::bundle_tooltip` asks the display first and then defers to
`bundle::tooltip_layout`; the tooltip draw uses it for the height probe
and for the draw alike.
A Resolution Scale leaves the pack's picture smaller than the window. Its final pass drew at the window's size, so a shader using gl_FragCoord as texel coordinates (Photon's final) only filled a quarter of the screen. Draw final at the picture's size into an offscreen texture and copy it once to the window with a screen-row fullscreen pass; the no-pack path and same-size output are unchanged.

IronGolem.doHurtTarget throws the target up only when the hit lands, by
0.4f * max(0, 1 - knockback resistance); Horizon threw everything it swung
at by 0.4. The hit and the toss are one event now, like the warden's
sonic boom.
IronGolem.aiStep ends in NeutralMob.updatePersistentAnger(level, true), the
same as a wolf's: every tick it holds a target, a monster too, the anger
timer restarts with a draw of the golem's random. Horizon only angered it at
a player who hit it, so a golem going after a monster drifted from vanilla's
random within a few ticks. The golem now uses the wolf's port, and its
player target goal asks isAngryAt.
LivingEntity.aiStep still drops motion below 0.003 and runs pushEntities
without AI; Horizon's NoAI branch skipped both, which the new mob AI
scenarios (a golem fighting a NoAI zombie, ravager and warden) showed.

A guest's use raised its opener count twice: open_menu counted the block entity's startOpen, then lan_open_container counted it again once the menu was sent. Closing lowered it once, to one, so stopOpen never ran and the lid stayed open with its raised collision (#9500).
The guest open path now relies on the count open_menu already made; the harness keeps the lid open and closed checks for both host and guest.

The tick cases' stand-in world stopped at y 32..96 and x/z -32..31, one block
short of every sample the loop takes and of the neighbours those samples read,
so a block at the edge compared air against the oracle's unending world: that
is where the beehive, the redstone ore and the pointed dripstone differences
came from. Fill the whole box plus a block either way, let a case name the
floor below y = 64, hand the loop the state's own fluid (a waterlogged block
has a water source, which it ticks and drips) and bind the client jar's block
tags in the oracle the way a datapack load does, which a bare bootstrap leaves
empty. Then add the families that read a neighbour, a shape or their own fluid:
dried ghast over soul sand, soul soil, stone and air; hives and a nest embedded
and hanging; a lit redstone ore and a deepslate one embedded and over air; and
stalactite tips over stone and water. 2,097 cases and 456,747 output lines
become 2,187 and 462,718.
BeehiveBlock.animateTick is a `for (i = 0; i < random.nextInt(1) + 1; i++)`
loop, so the bound is drawn again on the check that ends it: a hive always
spends two nextInt(1) draws around its single trySpawnDripParticles attempt.
Horizon hoisted the bound out of the loop and spent one, which left the level
random a draw ahead of vanilla from the first hive the ambient loop touched:
every particle after it moved, and the honey drip of a hive hanging over air
came out at the wrong column.
The corpus had no wither rose case at all. Add a world that is all wither rose,
run the whole ClientLevel.animateTick loop over it and compare every smoke puff
by exact position bits in call order: twenty-seven cases, three seeds and
twenty-four at random ones. The probe now supplies the flower's per-column model
offset the way the client's mesh tables do (a case without it would compare a
shape the game never shows). 2,070 cases and 402,440 output lines become 2,097
and 456,747.
WitherRoseBlock.animateTick reads its centre off getShape(state, level, pos,
CollisionContext.empty()), a flower's own box whose bounds centre is 0.5/0.5
before the block's per-column model offset. AnimateContext::shape_y answers with
the collision shape, which is empty for every flower, so the centre came out as
0 and the whole smoke column sat half a block towards the block's north-west
corner. Take the centre from the pick shape's boxes (BlockFacts::outline) and
keep the model offset on top of it.
The hooks that came before docs/native-hooks-neoforge.md had no
`neoforge`, `side` or `cancellable` keys, though NeoForge mods listen to
their events most: server and level ticks, block and item clicks,
attacks, joins, chunk loads, logins. Each value comes from the hook's
own doc comment or the vanilla method the proposal's table names, and
`cancellable` matches the hook's mod_api contract. Metadata only: no
name, signature or call site changes.
The proposal's status, its next-hooks table (most of it has landed)
and its capabilities and rollout notes now match main.

An icon-only button recorded nothing, so the pad could not reach the pause
menu's Report Bugs, Feedback and Player Reporting icons, or Realms' icons. An
active button with an empty label is now a focus target. So are the
Multiplayer warning's "Do not show again" box and Optimize World's Erase
Cached Data box, which A now ticks.
tools/pad_menu_e2e.py gains every_screen_has_targets, which walks the title's
submenus and every options page and fails on a focus screen with no targets.
Replay Studio is allowlisted because it registers nothing yet. New pause_icon
and erase_checkbox cases press the new targets. The pause menu now has
unlabelled widgets, so splitscreen_e2e's setup scenario reads labels with get.
controller_settings_pad's check for a Navigation page now matches exactly: it
tripped on the General page's Navigation Repeat rows.
docs/controllers.md no longer says every rectangle registers itself or that

The world's depth was bound as a depth texture and read with textureLoad, which naga's GLSL backend cannot emit, so TAA, the depth blit and the shader depth test failed to build on OpenGL. Bind those views as unfilterable float textures instead: wgpu accepts a depth view there, and textureLoad returns the same depth texel on every backend (Vulkan, DX12, Metal, GL).
The shader translation test now fails on any shader the GL backend runs that cannot translate, and pins fs_taa and fs_blit; the HUD's glint, which fails for an unrelated two-samplers-per-image naga limit, is the one allowed exception.

MultiPlayerGameMode.interact sends EntityHitResult.getLocation() minus
entity.position() in every ServerboundInteractPacket. Horizon sent a
fixed [0.0, 1.0, 0.0] for mobs, a point in their middle: armour stands,
saddles, leashes and anything else that reads the click carried
interactAt to the wrong place, unlike vanilla, and a server's reach or
ghost-hand checks saw clicks that vanilla never makes.
mob_hit and the spear's attack_range pick now return the point along
the view ray where the mob's box was met, measured from its feet, and
every caller destructures the third element. A regression test checks
the packet's point against the ray.
ServerGamePacketListenerImpl.handleInteract fires the trigger with the
held stack as it was before the interaction whenever an item interaction
succeeds. NameTagItem.interactLivingEntity and DyeItem.interactLivingEntity
both succeed, but interact_mob returned after name_mob and after the sheep

A location predicate whose `structures` named a tag

the world's pack tags didn't hold that registry. The world's tables now

Each player-* request writes one log line with what became of it: INFO
and what it did, or WARN and the reason it was refused. The line names
the player and, for the export, the import, the confirm, the release and
a named drop, the hand-over id, so the lines of one hand-over can be
found on both servers. The record and the request's body are never
written.
docs/server.md gives a hand-over in order, with the ids, the commit
point and what undoes itself, and the log lines.
tools/server_transfer_e2e.py runs a whole hand-over between two
dedicated servers over their real control sockets: two engines with
[transfer] on and Velocity forwarding, a small relay per engine that
answers the forwarding request as a proxy does, and horizon-bots
clients. It follows the documented order step by step, checks the
target's player file is on disk when the confirm answers and that the
source writes nothing for a player moved away, then aborts a hand-over
back and checks the player plays on.

The request may name where the player arrives, over the record's
compound: `position`, `rotation`, `on_ground` and, now that #8693 keeps
a guest's motion, `velocity`. They belong to the `position` part. The
pitch is taken as Entity.setXRot takes it (modulo a turn, then cut to
+-90) and the yaw as it is; a velocity component over 10 blocks a tick
is taken as 0, as Entity.load takes a saved Motion. A position must be
within the same bounds as the record's own (Entity.load's clamp:
30,000,512 on x and z, 20,000,000 on y), and a rotation or velocity must
be finite numbers.
When the import moves the player to another chunk than the one its view
was built around, the view moves at once: the chunk centre is sent
before the position to confirm, and the chunks out of reach are
forgotten. The reply says so with "recentered".

martipops's second review of #8730.
The commit point now covers the three files and a power loss: the
player file, advancements and statistics are each written to a new
file, synced, then renamed into place, and the folder is synced on Unix
(save::write_durable, write_dat_durable). Each write returns its error,
and the player stays held and imported when one fails. Ordinary saves
are unchanged.
A retry of `player-import` or `player-confirm` after the commit, whose
reply was lost, names the hand-over of a player already placed from it:
it is answered ok, placed, with `"retried": true`, and nothing is done
again. Another hand-over's id is still refused.
The record's health is refused over 1024 and its absorption over 2048
(max_health and max_absorption), its food exhaustion over 40
(FoodData.addExhaustion) and an effect amplifier outside 0 to 255, as
26.3's bytecode bounds them. A stack's count needs no check:
item_from_nbt already takes one outside ItemStack's 1 to 99 as 1.
docs/server.md says what a proxy does when `moved` is refused after the
commit (the freeze ran out, or an operator's /kill), and that it
confirms only while the export's `freeze_ticks_left` leaves it time.

`player-import <uuid> <json>` applies a hand-over's record (from
`player-export <uuid> freeze`) to the held player on the target, whole or
in parts, and tells its client what changed. Unless the request says
`"place": false`, it then places the player as `player-confirm <uuid>
<hand-over>` does.
Placing is the hand-over's commit point: the player file, advancements
and statistics are written to disk synchronously, then the player is
placed, and only then does the reply say ok. A proxy releases the
source after that reply, so a crash of the target no longer leaves the
only current copy in memory. If the file cannot be written the player
stays held and imported.
The record's hand-over id is bound to the held player at the import: a
record without one (an export without freeze) is refused, a retry of the
same record is taken and another hand-over's is not. `player-confirm`
names it, and `player-drop <uuid> [hand-over]` may: a named drop must
name the imported record's. A held player that is leaving (dropped or
kicked, its connection not closed yet) can be neither imported nor
confirmed.
The import reads the whole compound as a file load does: the keys
Horizon does not model, the mods' attachments (given to the game's own
map) and the body's values. The body follows the parts: fall and motion
with `position` (with the saved vehicle), air, fire, freezing and food
exhaustion and timer with `health`. Values no player can have are
refused before anything changes: a position, rotation, motion, health,
absorption, saturation, experience progress or fall that is not a
number, a position past vanilla's clamp, a health of zero or less.
The client is sent the effects the import removed and the recipe book
it brought. Every player gets the arrival's list entry, since every
player is shown its entity; `announce` is the join line only. At
confirm the client is sent its position and inventory again, since what
it did since the import was not acted on.
The control endpoint refuses a request line longer than 16 MiB, which
the game would otherwise read and parse between two ticks.

The config reply pinned by api-v1-config.json lists [transfer] with its

A login that used up a proxy's expectation (player-expect, taken as the
login starts) is held on the target server: it gets the whole join
sequence and the level around it, and its acknowledgements are handled,
but it is not placed. No join message, no list entry for the others, not
among the entities they are shown, not simulated, and nothing else it
sends is acted on. The world is loaded around a held player as around a
placed one. The log says "<name> is held: it arrives from another
server".
A held player nobody takes over is dropped after [transfer]'s
max_hold_seconds (60 by default, 1200 ticks), with one warning: a player
already kicked or dropped, whose connection is slow to close, is not
kicked again on every tick. horizon-server passes the setting with the
others.
A held player keeps a true picture of the others while it waits: a
player who joins meanwhile is added to its list, and one who leaves is
removed from it with its entity, or its client would drop the entity of
a player it has no entry for.
`player-drop <uuid>` forgets the player's expectation and disconnects
the held player without a save or a word to anyone. player-export
refuses a held player. Placing it is the import's work, next.

The row described it as missing because the prediction only restored the block.
It is game/remote.rs::Game::block_meets_player now, and end_predictions acts on
the answer.
Entity.isColliding on a full block at the player's feet meets a 0.6 x 1.8 box
standing in it, and a block above its head, the one beside it or an empty shape
does not. The snap takes the remembered position while the teleport guard allows
it, and nothing when the block came back clear of the player or the player was
teleported at the same sequence.
ClientLevel.syncBlockState is what BlockStatePredictionHandler.endPredictionsUpTo
calls once the server acknowledges a sequence: when the block takes a state it
did not have, the level restores it, and then, if the prediction remembered a
player position and the player was not teleported since
(lastTeleportSequence < sequence), it asks Entity.isColliding(pos, state) -- the
state's own collision shape at the player's pose against the player's box -- and
calls Player.absSnapTo with the remembered point when they meet.
Horizon's end_predictions restored the block and stopped there, so a break the
server refused under the player, or a placement it pulled back, left the player
standing inside it until its own physics pushed it out.
A prediction now remembers what vanilla's ServerVerifiedState does -- the
sequence, the state the server last gave the block, and the player's position
when the change was first predicted -- and keeps all three through a
retainKnownServerState that only bumps the sequence. end_predictions restores the
block, tests the shape against the player and snaps to the remembered point when
the guard allows it. remote_teleport takes BlockStatePredictionHandler.onTeleport,
so a prediction made before a teleport keeps its block but not its snap.

## What works today
- **The game:** vanilla world generation, mobs, villagers, raids, redstone, every command, the HUD and the recipe book, on vanilla saves. Worlds from 1.8 to 26.2 are upgraded. [Status](#project-status).
- **Extras:** new menus, graphics presets, distant terrain up to 1024 chunks, controllers, zoom, minimap and more, off by default where they change the vanilla look. [Settings](https://playhorizon.dev/docs/settings).
- **Packs:** resource packs, and data packs with functions, predicates, item modifiers and world generation.
- **Multiplayer:** invite friends with a code, Open to LAN, join servers (online mode included). [Multiplayer](https://playhorizon.dev/docs/multiplayer).
- **Mods:** content mods (blocks, items, data) and native Rust mods, built by the launcher with nothing to install. Java mod jars do not run. [Mods](https://playhorizon.dev/docs/mods).
Everything below is in the current release.
In the Rust client, with vanilla assets and no mods or shaders:
- **The game.** Survival, creative, hardcore and spectator; vanilla world generation in all three dimensions, mobs, villagers, raids, redstone, every command, the HUD and the recipe book. Vanilla saves open as they are, and worlds from 1.8 to 26.2 are upgraded.
- **Multiplayer.** Join vanilla and Horizon servers (online mode included), open a world to LAN, or invite friends with a code from the launcher's Home page.
- **Graphics.** Distant terrain up to 1,024 chunks, graphics presets, HDR and controllers, all off by default where they would change the vanilla look ([settings](https://playhorizon.dev/docs/settings)).
- **Packs.** Resource packs, data packs and shader packs ([below](#mods-and-shader-packs)).
- **Mods.** Content mods and native Rust mods, installed from the launcher ([below](#mods-and-shader-packs)).
- **Servers.** Host one from the launcher, or run `horizon-server` on a VPS ([below](#host-a-server)).
- **The launcher.** It installs and updates the game, prepares its files from your copy of Minecraft, and updates itself.

## Mods and shader packs
- **Content mods** (`.hmod`): blocks, items, recipes, loot, models and textures, with no code.
- **Native mods** (`.hnmod`): Rust that the launcher compiles into the game for you, with nothing to install.
- **Java mods** (Fabric, NeoForge, Forge) don't run: Horizon has no Java. The launcher carries over the data and assets inside their jars, and imports modpacks (`.mrpack`, CurseForge zips, Prism instances) the same way ([modpacks](https://playhorizon.dev/docs/modpacks)).
- **Shader packs**: Iris/OptiFine-format packs (`shaders/` folders) and Horizon's own WGSL packs, under Video Settings → Shader Packs ([pack format](docs/shaders.md)).
Mods are off by default: a fresh install plays exactly like vanilla 26.3. The launcher's Mods page browses Horizon's registry and Modrinth. [Mods](https://playhorizon.dev/docs/mods) · [make a mod](docs/mods.md).
## Host a server
The launcher's **Servers** page creates, starts, backs up and updates a server, and invites friends over Tailscale. On a VPS, `horizon-server` installs with one command and needs no Java. [Host a server](https://playhorizon.dev/docs/hosting) ([reference](docs/hosting.md)).
## Modpacks
The launcher imports Modrinth and CurseForge packs and plays the mods Horizon can carry over: today, content mods made of data and assets, not Java code. [Modpacks](https://playhorizon.dev/docs/modpacks).
The launcher's **Servers** page creates, starts, backs up and updates a server, and invites friends. On a VPS, `horizon-server` installs with one command, needs no Java, and takes vanilla 26.3 and Horizon players alike.
