🤖 Agent: lightning now places fire (and draws its extra-source offsets) only when canSpreadFireAround passes at the bolt, so fire_spread_radius_around_player holds for strikes far from every player.
🤖 Agent: the Mods page's install and port messages go through tr/trf with named arguments, so they translate; lang files merged key by key onto main, i18n tests pass.
🤖 Agent: a mob's Absorption now refills on every accepted add (AbsorptionMobEffect.onEffectStarted), and heal/harm and effect intervals shift like Java's int << / >> (distance mod 32, wrapping) instead of clamping or panicking at amplifier 32+.
🤖 Agent: an empty frame now refuses a map tracking more than 256 counted markers (ItemFrame.interact's isTrackedCountOverLimit FAIL): the map stays held, no swing; exactly 256 still goes in.
🤖 Agent: /say from a command block reaches every player under the block's name, and a captured guest command no longer echoes it back as feedback (kacpherek's point); lan_e2e command-block-chat not run here.
LightningBolt.spawnFire places fire, and draws its extra sources, only when
ServerLevel.canSpreadFireAround passes at the bolt: the
fire_spread_radius_around_player rule now holds for lightning (#11376).

🤖 Agent: the omen sound now plays from the player's addEffect for any newly added omen (command, potion, mod) at the feet, as MobEffect.onEffectAdded does; the three special paths moved from the eye to the feet too.
🤖 Agent: TNT, falling blocks and XP orbs now collide with boats, shulkers and a held happy ghast (Entity.collide's canBeCollidedWith); sand landing on a boat over air breaks into an item like vanilla's wouldContinueFalling.
🤖 Agent: 0.2 shader packs get the float HDR frame only under HORIZON_HDR_FRAME=float; the default and 0.1 paths keep their formats (frame_format tests cover both), so the vanilla look is unchanged.
🤖 Agent: a loaded furnace keeps its saved cooking total until the item finishes, and a hopper or dropper filling the empty input slot restarts the cooking as setItem does (kacpherek's point); furnace_loaded_total and furnace_output_components pass.
🤖 Agent: a restored chat draft draws grey italic until edited, as ChatScreen's isDraft does; text a mod opens chat with is not a draft. Merge with main builds and the chat tests pass.
ItemFrame.interact returns FAIL when MapItemSavedData.isTrackedCountOverLimit(256):
the map stays in the hand and the frame stays empty (part of #11383).

🤖 Agent: Frost Walker's speed modifier now follows a boots change made by a guest too (the guest's armor is swapped in before the comparison); armor_changes copies only changed slots. armor_stand_frost passes on a union with main.
🤖 Agent: a spectator using a portal block travels to its destination, never builds a Nether exit, and gets spectator.cannot_teleport without one (ServerPlayerGameMode.useItemOn); nether_portal harness passes on a union with main.
🤖 Agent: damage a mob's absorption takes is credited to the thrower (guest throws settle inside as_guest, kacpherek's point); mace and trident harnesses pass on a union with main.
🤖 Agent: region saves reuse one deflater per writer instead of building one per chunk; the test checks the compressed bytes are identical to a fresh deflater's. Union check (main + the gate's 9 heads): fmt, clippy -D warnings, 5666 tests green; verify green after the runner's full-disk rerun.
🤖 Agent: the second rider's PlayerInput/MoveVehicle is now ignored like vanilla's getControllingPassenger check; riders are listed in boarding order so the first one in keeps the tiller.
🤖 Agent: only SUCCESS_SERVER block uses (beds, light, a charged anchor, signs) swing back to their own player; item and entity uses still echo, as the body says. use_item_on, flat_place and dedicated_server pass locally.
🤖 Agent: each moving block's collision view now advances right after its own push, so later pushes in the same tick see it at its new progress; the cost is one lookup per moving piston. piston_push and piston_movement pass locally.
LivingEntity.addEffect runs onEffectStarted for every effect it accepts,
so Absorption given again refills a mob's shield to 4 per level of the
effect given. Horizon refilled it only for a new or stronger effect.
HealOrHarmMobEffect and the periodic effects use Java's shifts, which take
the distance modulo 32 and wrap: amplifier 32 is amplifier 0 again, and a
ticked heal is at least 0. Horizon clamped the distance to 30, and an
amplifier of 32 or more panicked on Regeneration's interval in a debug
build (#11386).

🤖 Agent: horn and brush uses end with stopUsingItem (the interaction vibration), and a mob in front of the brushed block stops the brush out to the block reach; item_use_catalog harness passes on a union with main.
MobEffect.onEffectAdded plays Bad Omen's, Trial Omen's and Raid Omen's
sound (withSoundOnAdded) whenever LivingEntity.addEffect adds one that
is new, at the entity's feet. Horizon played them only on the raid, bottle
and trial spawner paths, at the eye, so /effect give, a potion's custom
contents or a mod adding one was silent (#11373). The generic add now
plays it for players and, from /effect, for mobs; the three special paths
play at the feet.

🤖 Agent: the item name and the action bar take fixed heights above the hotbar (Hud.extractSelectedItemName 59, extractOverlayMessage 68) instead of following the bars; hud harness passes on a union with main.
🤖 Agent: a breeze turns a thrown potion back at half speed (Breeze.deflection) once in a row, stopping at the hit point that tick; the REVERSE draw uses the potion's own random.
🤖 Agent: advancements with no criteria get their rewards on load (checkForAutomaticTriggers) but stay not done, as AdvancementRequirements.test answers false; checked on a union with main.
🤖 Agent: the fade out ending at startFadeIn now runs to the end of the day (since()==0 read as DAY), which was kacpherek's review point; checked on a union with main (fmt, clippy -D warnings, tests).
🤖 Agent: the solid terrain pipelines are built with HDR_LIGHTING off and the lit copy only exists when hdr_output is Some, so HDR players switch per frame by self.hdr; frame-identity label makes CI check HDR off, offscreen HDR and HDR toggled off in a running game. −16 to −22% GPU on M4 Pro, image identical in-process.
🤖 Agent: merging. Empty region files (13 303 of 13 620 in the test world) are no longer rewritten and synced on world open, and region files convert on all cores but one with byte-identical output; datafix harness 6/6.
terrain.wgsl's solid shaders carry HDR output's lighting behind a runtime
`hdr_light.z` test. The branch is never taken without HDR, yet on Apple GPUs its
code alone costs ~15% of the solid pass (register pressure). A pipeline
constant `HDR_LIGHTING` now guards it: the solid pipelines (per-section, pulled
and flat) are built without it, and a copy with it only where the display
offers HDR output, picked per frame by whether HDR is on.

🤖 Agent: the session state a client HUD reads (world id, screen kind) comes from fields the window already keeps; merged with #10195 and checked with clippy, the native_client tests and the hook stamp test.
🤖 Agent: client_hurt reports the packet's causing entity (the shooter, not the arrow) and treats an untracked entity as not a player, so a mod never gets a false PvP signal. Main merged in (test conflict with #11512's open-chat test, both kept); verify green on this head.
PrimedTnt, FallingBlockEntity and ExperienceOrb move with Entity.move,
whose Entity.collide includes EntityGetter.getEntityCollisions: a boat,
a living shulker and a happy ghast held still stop them, as they stop a
dropped item. Horizon resolved their moves against blocks and the world
border only (#11518). The ordered tick gathers those boxes once per run
(again after an explosion) and passes the nearby ones to each move.

A boat's passengers went to the clients in the order the players joined
the server, so the player who got in second could hear it sits first and
take the boat over, and the server took MoveVehicle from either seat: with
two players in one boat it kept snapping back (#11541). The passengers now
go in the order they boarded, and handleMoveVehicle ignores a player who
isn't the vehicle's controlling passenger, as vanilla does.

🤖 Agent: native_set_chat_input filters text to what typing allows (no control chars, DEL or §) and clamps the cursor, so a mod can't inject formatting codes into the chat box.
🤖 Agent: Launcher-only follow-up to #10529: the Home tab strip is flex_none on wide windows again (glass::tabbed keeps its notch at 1440 px) and only scrolls when compact; settings rows keep 40 px between name and control and wrap the control only when narrow. No new strings; fmt/clippy/tests green on the union of this wave's heads.
🤖 Agent: follow-ups to #11033/#11044/#11043/#11016 that missed the merges: death protection is one prototype lookup per hand per tick (was a full component map for every armed mob), checked against the component map for patched and stripped stacks. Union check: fmt, clippy -D warnings, 5666 tests green.
🤖 Agent: the interpolation change is checked bit for bit against the old formula over the test's whole range, so no position moves; one multiply fewer per entity per frame. Union check (main + the gate's 9 heads): fmt, clippy -D warnings, 5666 tests green.
🤖 Agent: inflates each region chunk in place instead of through a second buffer; the differential test decodes the same chunks with the old block decoder and compares every section. Union check (main + the gate's 9 heads): fmt, clippy -D warnings, 5666 tests green.
🤖 Agent: Optimize World now upgrades region files in parallel with one sync per file instead of one per chunk (F_FULLFSYNC on macOS was the cost); the 1-vs-4-thread test checks the counts against the fixture's own layout, and a canceled recreate leaves every file untouched. Union check: fmt, clippy -D warnings, 5666 tests green.
🤖 Agent: the launcher keeps each native shader's identity and options across the settings screen rewrite; its parent #10168 is merged, and the union with main passes clippy and tests.
🤖 Agent: client mods read entities and textures through the Host only, no new write path; #10196 conflicts with it in native_client_services.rs and gets main merged after this lands.
🤖 Agent: the invite-code calls go through one frontend() helper with x-mojangauth, only to the Realms frontend URL; builds and tests clean on a union with current main.
PistonMovingBlockEntity.tick pushes entities from each block entity's own
tick, and getCollisionShape reads its progress: the moving blocks that
ticked before it have advanced, the ones after it have not. Horizon
pushed every entity against last tick's progress of all of them, so a
TNT duper's TNT was pushed through a block that was about to move
(#11399). Each piston's collision view now advances right after its own
push.

🤖 Agent: native_take_screenshot refuses while another screenshot waits for the frame, so a mod's call can't overwrite F2's or the world icon's pending grab.
🤖 Agent: parity.py starts harnesses with no arguments; these two required --binary/--work-dir and failed parity-main in 0 s. On the desktop both now reach their servers (the Java sides ran); the full runs there timed out only because the desktop's swap was full.
🤖 Agent: removes only the minecart boxes from the item's collision list; boats, shulkers and a held happy ghast still hold items, as AbstractMinecart doesn't override canBeCollidedWith. entity_collision, held_drop, shulker_space, boat_item_hit pass locally.
🤖 Agent: merged after #11019 and main (hook and doc blocks kept whole, quinn kept beside the new optional crates). Without a mod, PlayerSender::send pays one relaxed WATCHED load and sends the bytes as they were, and worldgen, LOD columns and redstone keep vanilla's values.
🤖 Agent: the check, not the 1.8 rules, was broken: the switch row sat half under the list's edge so the click missed it; verified 7/7 legacy, 9/3.6 modern on the Mac.
🤖 Agent: the fight bots' swing carried a hand byte 26.3's swing packet doesn't have, so every server kicked them on the first hit; it now sends the same Punch as --attack.
🤖 Agent: twelve hook groups land together. Without a mod, the move, teleport and trample hooks are fn pointers over an empty mods() slice, so a player's move costs one indirect call and no allocation; a mod command's permission node falls back to its own level when no provider answers.
🤖 Agent: only the slider's step table changes; saved values between steps snap to the nearest step (test covers 3000 → 13/23), so existing options.txt files still load.
🤖 Agent: quinn is optional behind the quic feature with default features off (runtime-tokio + rustls-ring only), so no extra TLS backend lands in Cargo.lock beyond the 7 packages.
The check failed on main with 1.8 rules that work: the switch row now sits
under the PvP page's HUD rows, the scroll stopped as soon as the row showed
at the list's lower edge, and the click at its centre landed outside the
list, so the rules never turned on (legacy hit 9, not 7). It now scrolls
until the row stops moving and asserts the click flipped it.
The swap and back went out in one tick: since the client sends a slot
change from its next tick, as vanilla does (#10084), that sends nothing,
and the modern hit kept its full charge. The stick is now held 3 ticks.
Mac mini: legacy (7, 7), modern (9, 3.6).

🤖 Agent: .github only; the by-hand ARM64 job's launcher --version step now runs from bash as launcher.yml does, and passes on the ARM64 runner (run 42320852405), where the pwsh version failed on any code.
Opening a world saved by an older version runs the converter in
datafix/files.rs (upgrade_world), which rewrote every region file on one
thread. Now:
- upgrade_regions spreads a folder's region files over worker_threads()
workers (all cores but one). Each file is still read, fixed and written
whole by one worker through the same staging folder, so the bytes do not
depend on the thread count. A cancel or an error stops every worker
before its next file; the error returned is the first file's in order.
- A region file without chunks is left as it is instead of being rewritten
as an empty 8 KiB file and synced. The game leaves many of them: 13 303
of the 13 620 overworld files of a 1.21.1 ATM10 test world.
Tests: 4 workers give byte-identical files to 1 and every chunk at the
current version, an empty file stays empty, and a cancel from the first
chunk converts at most one file per worker and leaves the rest old.

🤖 Agent: one line in docs/hosting.md (Intel Macs have had server builds since the 10-31 Nightly; install.sh already maps Darwin-x86_64); the README half is already on main via bf4657da26.
🤖 Agent: Auto's backend order now reads the machine's arch (IsWow64Process2), so the x64 build on a Snapdragon PC starts on DX12 like the ARM64 one; the ARM64 runner built and started the game on this head. Unverified on real Adreno hardware (asked #7513's reporter).
🤖 Agent: merged main in again (only the test module list in pack_post.rs collided, with #11196's sky_disc_blend_tests). The last parity failure on 4fa3bf699 was command_exec's '/advancement grant @s everything' count (116 vs 115), which fails identically without this PR; this head reruns parity. sizes_differ is a few array reads per pass per frame.
The fight behaviour's swing went out as a raw Punch with a hand byte
26.3's ServerboundSwingPacket doesn't have: every server kicked the bots
on their first hit ("packet 46 was larger than expected: 1 extra bytes").
It now sends the same Punch as --attack.
--crits makes fight bots swing at a sword's full strength (13 ticks) and
jump into every other swing, landing it on the way down: a critical hit,
then a sweep from the ground. tools/perf PvP scenes get crit and sweep
particles from real hits.

tools/parity.py starts every harness with no arguments, and both scripts
required --binary and --work-dir, so parity-main failed them in 0 s

hostile_sound_categories, they now build the game through net.sides and
pick a work folder under .local/ when none is given.

Follow-up to #10529 (atsauban's responsive wrapping). The Home tab strip
took the full width at every size, so glass::tabbed drew one plate and
lost its notch even at 1440 px: it is full width and scrolls only when
compact. setting_row went from 40 px to 16 px with justify_between for
every row; it keeps 40 px between name and control and wraps the
control under the name (12 px) when the window is too narrow. The
breakpoints are named constants beside WIDE.

- Death protection: one prototype lookup per hand instead of a component
map rebuilt from the stack's patch. update_totem_ready runs for both of
the player's hands and sync_mob_death_protection for every armed mob,
every tick; only a stack that patches the component takes the old path.
- Remote projectiles: the swept bubble-column cells are deduplicated
without a HashSet per projectile per tick.
- Ident::read hands a namespaced identifier back without a second String.
- parked_worlds keeps its doc comment (#11016 put parked_border under it).

handleUseItemOn sends the use's swing to the player's own client only when
the result is not SwingSource.PREDICTED. Horizon sent every swing back, so
on a slow connection the echo of a placement's swing arrived after the first
half of the client's own swing and swung the arm again (#9887). A placement
and a block's own SUCCESS now count as predicted; the beds, light block,
respawn anchor and sign stay SUCCESS_SERVER and are still sent back.

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.

A server seating the player on a block display (sit mods, NPC plugins) took the vehicle for a minecart; none was
found, so riding was dropped and the player fell into the slab under the seat (y -61.0 where the server keeps
-60.1). The seat is the vehicle's riding position less the player's vehicle attachment (0.6, scaled).

AbstractFurnaceBlockEntity.setItem resets the time; without the early reset a hopper-fed furnace would smelt its first item in one tick. Review feedback on #10170.

`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
while dmg < 3.4028235E37F. Horizon awarded every hurt with Rust's round,

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

A modded 1.21.11 server's own entity type (Sit's sit:entity_sit is 157) kept its number, which in 26.3 is

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).

Client mods such as radars, name tags and spectator ESP need the
entities the client shows, with what they look like, without reaching
into Game's internals. API 411's native_client_entities had ids,
positions and player profiles, but no type, babyhood or texture, and no
dropped items.
- NativeClientEntity gains kind, yaw, baby, spectator and the texture
its body draws with (mobs::render::body), plus position_at, the
renderer's interpolation. The struct is non_exhaustive, so existing
mods keep building.
- native_client_items lists the dropped items the client shows.
native_item_entities stays server-only, so server logic never acts on
a client's copies.
- native_client_texture returns TexturePixels by the name texture and
NativeClientProfile::skin give: a downloaded skin from memory, else
native_client_resources().texture(name).
Pending fragment client_entity_list. Tests: position_at between two
ticks, and a client fed the server's play packets reading a zombie, a
calf, a spectating player with its default skin and a dropped item
through Host, plus texture pixels and a refused path out of the packs.

Add the `native_client_resources()` helper. It returns `ClientResources`
over the resource tree the game loaded, which is vanilla's with the
resource packs turned on and the content mods' files over it. A client
mod fetches it on the game thread and can then use it on any thread.
`read(path)` returns a file's bytes for a plain path under `assets/`,
such as `assets/minecraft/textures/entity/cow/cow_temperate.png`.
`texture(name)` decodes a texture by name (`block/stone`,
`entity/cow/cow_temperate`) into `TexturePixels`. Paths outside
`assets/` return none, so Horizon's own prepared tables stay private.
Mods stop reading `options.resources` with `atlas_sources::texture_path`
and `prepared_files::read`. The tests build a folder resource pack over
a fake vanilla tree and check that the pack's texture wins, and that
paths outside `assets/` are refused.

Add the `native_block_states()` helper. It returns `BlockStates`, a copy
of every block state keyed by its `BlockStateId`. A client mod fetches it
on the game thread and can then use it on any thread.
Each state's `BlockStateFacts` holds the block name, air, invisible,
`FluidState`, waterlogged, light emission, outline boxes, map colour and
whether the state can collide at all. `sprites(id)` returns what the
state's model draws on each side, as `native_block_sprites` does for a
block name. `texture(sprite)` names the texture behind a sprite, the
inverse of `native_texture_sprites`. `mod_api` now also exports
`FluidKind`, the type `FluidState::kind` returns.
The table copies the game's internal facts into stable public types.
Client mods that draw blocks their own way, such as minimaps, world maps
and radars, no longer need `res.facts()`, `res.collision()` or
`block_sprites::Lookup`, which change from commit to commit.
Tests run on real prepared resources (ignored without
HORIZON_TEST_RESOURCES): grass block facts, air and light, slab
outlines, and a grass block's face texture names.

whose block-item sheets (ITEM_CUTOUT, ITEM_TRANSLUCENT) cull back faces. Only the
enderman's carried block culled, so the coplanar faces of the other layers' cross
models z-fought as the mob moved (#5301).
The cull now goes by each quad's winding, as the GPU's does, rather than the baked
facing, which is the nearest axis and 45 degrees off for a cross model's planes.

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
exercised, and the oracle skipped the gate entirely. Fixture lines now carry
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.
68992/68992 enchanting cases match.
A crystal's spin and bob start from a random draw. Which crystal gets which
draw, and a server's entity ids that seed a client's copies, follow the order

draw is still made, and normal play is unchanged.

Gui.setScreen runs KeyMapping.releaseAll for every screen and
Minecraft.tick skips handleKeybinds while one is up, books, the sign
editor, dialogs and prompts included. Horizon keeps Screen::Playing under
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"
(screen_over_playing) in place of the dialog alone, and remote_handle_input
is not ready while one is up.

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).

LivingEntityRenderer.isShaking is isFullyFrozen (DATA_TICKS_FROZEN at or
over 140), and setupRotations wobbles the body while it is. Mobs and
other players already shiver, but the window's own model, rebuilt each
tick by tick_player_model, never got the player's frozen ticks, and the
window ignored the DATA_TICKS_FROZEN its server sends it, so a player in
powder snow stood still in third person.
The own model takes ticks_frozen from the player's body, and own entity
data index 7 sets it on the window's player as LocalPlayer reads it.

Guard against negative scale values producing excessive shift
distances in CheckerboardBiomeSource::noise_biome by clamping
scale to a non-negative lower bound before adding the +2 offset.
This keeps the shift distance within a sane range and avoids
surprising behavior for out-of-range runtime scale inputs.
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
fields. Horizon listed WitherSkull as not saved, so a skull still in
the air when its chunk unloaded was gone when the chunk came back,
and a blue skull came back as nothing.
Write and read the skull the same way as the fireballs: `dangerous`
as a byte (absent means a black skull), and no `Fire` since
WitherSkull.shouldBurn is false. The fire rule now keys on the
fireballs proper (is_item_fireball) instead of "not blast-immune",
which would have lit a saved skull.

tools/test_block_removal_parity.py only ever mined as a survival player:
every mine case ran ServerPlayerGameMode.destroyBlock in SURVIVAL, so the
creative branch (Player.preventsBlockDrops, no mined statistic, no tool
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
hasInfiniteMaterials) and the real CREATIVE game mode; the game's dispense
fixture sets the same mode for the case. --survival-only reproduces the
corpus as it was before this change.
4000/4000 cases match on the new corpus.
The overlay formatted its lines and laid out its glyphs every frame. It now
paints at most 20 times a second and copies those vertices in between, and
repaints at once for another window size, GUI scale or font epoch.
- The refresh rate is read at most once a second: on Windows, winit calls
EnumDisplaySettingsExW each time. The Window line uses the surface size.
- Passes are timed only while the overlay lists their times, at most 10 frames
a second. gpu-passes and HORIZON_SHADER_PACK_TIMING keep every sample.
- The CPU name is read in the background when the window opens: on Windows it
starts reg.exe, which the first F3 frame waited for.
- DebugEntries::any_enabled and status no longer build a String per entry; the
game asks every frame, F3 closed or not.
- Closing the overlay stops the server thread computing its lines each tick.
- The Mem, Allocation rate and Allocated lines now show on Windows.

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
(ColorTargetState.DEFAULT, no blending), the sunset fan translucent and
the stars with RenderPipelines.STARS (BlendFunction.OVERLAY: colour
SRC_ALPHA ONE, alpha ONE ZERO). Iris 1.11.7 drew them so with probe packs
of ours: the sky disc kept exactly what the program wrote, (0.3, 0.6,
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
the stars, now draw with pipelines of the same program that blend so,
keeping a blend.gbuffers_skybasic.<buffer> the pack sets (Iris blended
the disc into that buffer only).

A program writing a float vec4 into an integer colortex (RGBA32UI...) was
refused: wgpu has no float output into an integer target, so the whole

and the integer buffer read the floats' bits back (GL leaves that value
undefined; these are NVIDIA 615.78.08's). The output now writes the
float's bits as the buffer's integer type.

Horizon always made its default noise texture 256 wide. Iris 1.11.7
made it the size a pack's `const int noiseTextureResolution` gives, when
declared in a fragment shader (composite, deferred, gbuffers, final, or
shadow.fsh with no shadow pass), and ignored it in a vertex shader, in
probe packs of ours. The setting is now read like a colortex format.

`.length()` of a runtime-sized array in a named buffer block made naga's
validator refuse the program: its GLSL frontend loads the array and takes

ours and read the buffer's length (bufferObject size / stride).

Horizon decided whether to run the shadow pass from the samplers of the
programs' vertex and fragment stages only. A pack whose only reader of
shadowtex0 or shadowcolor0 was a compute stage (prepare.csh alone, or a
composite.csh beside a composite.fsh that reads none) got an empty map
(1.0), while Iris 1.11.7 drew it for probe packs of ours (0.3956 depth,
0.251 shadowcolor0 at our noon scene). Compute stages now count as the
other stages do.

every program that declared it layout(r11f_g11f_b10f), since the shader's
storage format no longer matched the texture. Iris 1.11.7 stored into such
an image and read it back, with a probe pack of ours: (0.25, 1.5, 3.0)
read back as written, alpha 1, also filtered between texels. The image is
now Rg11b10Ufloat where the device stores into that format; elsewhere it
stays the RGBA16F stand-in, and the shader's image declares that format.

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.
A client mod (battle music, a combat HUD) couldn't hear its own player's
fights on a remote server: the attack and damage hooks run where Horizon is
the server. native_client_attack(target, player) fires when the attack packet
leaves; native_client_hurt(attacker, player) when the server's damage event
for this player arrives, with the causing entity it names and whether this
client knows it as a player.

does (DataComponents.COMMON_ITEM_COMPONENTS). Since #10272 Horizon posts it, so the harness

as vanilla: 5200/5200.

🤖 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.

- Each worker looks at the cancel flag before every chunk, not only before
every file, so Cancel stops within a chunk on large region files. A
canceled file is never swapped in by recreate_region_files.
- The writes of a region file reach the disk once, when the file is done,
instead of a sync_data after every chunk. On the ThinkPad (NVMe, ext4) the
per-chunk sync was half of a 1.21.1 world upgrade (187 s -> 89 s, one
thread); on macOS sync_data is F_FULLFSYNC and costs far more.
- The calling thread is worker 0 and helpers are named World Upgrader #N;
a helper that fails to start leaves its files to the others.
- Tag modifiers are no longer cloned per chunk; the recreate folder is made
once per file.
- Tests: the parallel/one-thread comparison also checks vanilla counts
computed from the fixture; a new test cancels from the first chunk with 4
workers and checks at most 4 chunks were looked at and that a canceled
recreate leaves the world unchanged.

🤖 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.

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)

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

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).

A chunk's noise volume is made of whole cells, and InterpolatedSampler
filled it one cell at a time: per cell eight corner loads and four Z
lerps, per column two X lerps and a bounds-checked index, then a scalar
loop of stores and additions (fill_cell alone was 6.4% of the Overworld
proto phase's instructions). For a volume aligned to its cells,
fill_whole_cells now walks the four columns of one Z row of a cell from
the bottom of the volume to the top. The X lerps at a level of corners
are computed once (they are the top of one cell and the bottom of the
next: the same lerps of the same samples), the four columns' repeated
additions run as four lanes, and four Ys of the four columns are stored
as four vectors. Each value comes from the same operations on the same
operands in the same order as vanilla's InterpolatedFunction fillCell;
only the order between columns changes. The top cell may be cut short
(the 16x114x16 volumes); a volume that is not aligned, or whose top
corners would clamp, keeps the general path.
fill_noise_inner spent about ten instructions on each air block above
the aquifer's skip height. A downward run of non-positive densities that
stays above it is now skipped in one step: nothing was written for those
blocks and note_skipped only clears a flag, so one call covers the run.
Exact: chunkgen_bench --snapshot files (terrain and decorated) are
byte-identical to main in 16 cases: the Overworld at seeds 12345, -1,
987654321 and -7, the Nether at seeds 12345 and 42, the End at seeds
12345 and 7, sizes 3 to 12. A new test compares sample_volume and the
new path with a transcription of vanilla's sampleWithBlockStep and
fillCell, on an input with NaNs, infinities, signed zeros and
subnormals, for 4x8, 8x4, 4x4 and 8x8 cells, and checks which volumes
the new path takes.
Proto-phase instructions (callgrind, 64 chunks, one thread):
Overworld 5.970 G -> 5.615 G (-5.9%), the Nether 2.868 G -> 2.853 G

🤖 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
its volume and three quarters of its pitch, not for a silent mob or air.

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.
- NativeEffect (player_effects) and NativeInventoryKind (set_inventory) are pub and re-exported in
mod_api: the generated mod API refused both fragments.

#10398 asked that a local build in a folder with a space still builds: a

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

Unproven: not yet compiled or probed live (build queue); the integration branch tests it.
native_item_dropped_v2(player, stack, cancel) is now cancellable, as
NeoForge's ItemTossEvent is: a canceled throw puts the stack back into
the player's inventory (Inventory.add, the held slot first); only what
does not fit is thrown, unheard, and native_item_dropped hears nothing.
The drop statistics and the swing still happen, as in NeoForge. Wanted
by the combat log, freeze and inventory-lock ports.
Unproven: this commit was neither compiled nor run (builds were stopped for
the integration test); `cargo run -p xtask -- mod-api` filled the dispatch.
The listen-only v2 drop hook before it was proven on a server.
Part of #10461.
native_projectile_world_border(dimension, entity, kind, pos, velocity,
collide) is heard each tick a thrown projectile (pearl, snowball, egg,
potion...) inside the world border would end its next step outside it,
before 26.3 stops it on the border like a wall (MC-310476). A mod may
change its position and velocity, or set `collide` false: that tick's ray
is then clipped without the border, so it flies through as before 26.3.
Arrows and tridents, which Horizon does not stop at the border, are not
heard. Static (no self), called from tick_projectiles.
Unproven: not compiled or run on a server on this branch (handed to the
hooks-all integration build).
Part of #10461.
native_trample(dimension, entity, kind, pos, fall_distance, cancel) is
heard when a player or mob that fell onto farmland is about to turn it to
dirt, once FarmlandBlock.fallOn's chance and checks have let it (NeoForge's
FarmlandTrampleEvent, Bukkit's PHYSICAL PlayerInteractEvent and
EntityInteractEvent). Canceling keeps the farmland and its crop; the fall
damage is taken either way. The landing rules ask through a new
BlockLandingWorld::trample_allowed (true by default), which the player's
and the mobs' landing worlds answer from a function the game sets once
(block_contact::TRAMPLE); there is no self.
Unproven: not compiled or run on a server on this branch (handed to the
hooks-all integration build).
Part of #10461.
native_player_respawn_position(player, name, dimension, pos, yaw, pitch)
is heard once per respawn, after the Respawn click and before the player
is placed (NeoForge's PlayerRespawnPositionEvent, Bukkit's
PlayerRespawnEvent.setRespawnLocation), with their respawn point: a bed
or anchor block's top, a forced point, else the world spawn. Left alone,
the point is resolved as before. A changed dimension or position places
the player exactly there, with no bed or anchor used and no free column
looked for; yaw and pitch set their look, which Hub::respawn now takes
instead of always 0, 0. An unknown dimension or a non-finite value
leaves that part unchanged.
Unproven: not compiled or run on a server on this branch (handed to the
hooks-all integration build).
Part of #10461.
native_player_teleport(player, name, cause, from_dimension, from,
to_dimension, to, relative, cancel) is heard before a server player's
teleport is sent (Bukkit's PlayerTeleportEvent, NeoForge's
EntityTeleportEvent): commands (/tp within a level and into another),
ender pearls, chorus fruit, the spectator teleport menu, a dismount and
other server moves of the player. A mod may move `to`, cancel (the
player and their body stay where they are), or set the look and motion
bits of the position packet's relative flags, so a pearl can keep the
player's speed (0x1f8, what 26.2 sent); the position bits are ignored.
The call sites name the cause in a thread-local (lan::hub::teleport_cause)
that Hub::teleport and Hub::teleport_keeping_motion read; a teleport
without a named cause (respawns, portals, the End gateway, vehicles
carrying riders, waking up, refused moves) is not heard. Command and
spectator teleports into another level carry their cause in
LevelTeleport. The hub reaches the hook through a function the game sets
once (lan::hub::PLAYER_TELEPORT); there is no self.
Unproven: not compiled or run on a server on this branch (handed to the
hooks-all integration build).
Part of #10461.
native_player_move(player, name, from, to, yaw, pitch, on_ground,
cancel) is heard for each position or look packet that changed either
and passed the server's checks (moved too quickly, moved wrongly, the
anticheat), before Hub::position_change applies it (Bukkit's
PlayerMoveEvent). Canceling sends the player back to `from`, as a
refused move does; a changed `to` puts them there and their client gets
a teleport. Riders, sleepers and moves while a teleport waits are not
heard. The hub reaches the hook through a function the game sets once
(lan::hub::PLAYER_MOVE), as the damage hooks do; there is no self.
Unproven: not compiled or run on a server on this branch (handed to the
hooks-all integration build).
Part of #10461.
The helper native_respawn_player(uuid) respawns a dead server player as
their client's PERFORM_RESPAWN does (Spigot's player.spigot().respawn()),
after the players' packets of the server tick, through the same
guest_respawn. Nothing calls it without a mod.
Unproven: not yet compiled or run on a server (builds stopped for the hooks-all integration).
The helper native_set_flight(uuid, allow, flying) lets a server player fly
in any game mode or not and sets whether they fly now, as Bukkit's
Player.setAllowFlight and setFlying: the guest keeps the mod's mayfly
(allow_flight) until their game mode changes or they respawn, their
abilities packet and the server's body carry it, and the flying check does
not kick them. Without a mod allow_flight stays false and every check is
the game mode's, as before.
Unproven: not yet compiled or run on a server (builds stopped for the hooks-all integration).
The helpers native_mount(entity, vehicle), native_dismount(entity) and
native_eject_passengers(vehicle) seat a server player or mob on a boat,
minecart or mob, take it off, or take every rider off, as /ride does with
its checks and native_entity_mount (Bukkit's addPassenger, leaveVehicle,
eject). /ride's mount checks move into ride_mount, which both use; the
command's answers are unchanged. Nothing calls the helpers without a mod.
Unproven: not yet compiled or run on a server (builds stopped for the hooks-all integration).
native_vehicle_moved_v2(player, dimension, vehicle, kind, from, to, cancel)
is heard right after native_vehicle_moved, with the same state swapped in,
and also for a mob a server player rides. A canceled move puts the vehicle
back at from with its riders, a changed to puts it there
(native_teleport_vehicle), as Bukkit's VehicleMoveEvent with a teleport.
v1 keeps its signature, firing point and vehicles. Without mods nothing
moves the vehicle.
Unproven: not yet compiled or run on a server (builds stopped for the hooks-all integration).
The helper native_teleport_vehicle(dimension, id, pos) teleports a boat,
minecart or ridden mob of the level in place with its riders, as /tp does
a vehicle (Bukkit's Vehicle.teleport): the riders stay seated and a server
player riding it is told, as their client drives it. Only where nobody's
state is swapped in. Nothing calls it without a mod.
Unproven: not yet compiled or run on a server (builds stopped for the hooks-all integration).
The helper native_teleport_player(uuid, dimension, pos, yaw, pitch)
teleports a server player as /tp does (Bukkit's Player.teleport): at once
when they are the acting player or nobody's state is swapped in, else
after the players' packets of the server tick, so a port no longer runs
execute in .. run tp from the console, which waits for the next tick and
does nothing inside a player's hook. Into another level it is a command's
level teleport. Nothing calls it without a mod.
Unproven: not yet compiled or run on a server (builds stopped for the hooks-all integration).
The helper native_resend_commands(player) sends a player their command
tree again, with native_player_commands_sent, its v2 and the permission
nodes of the mods' commands asked anew, as Bukkit's Player.updateCommands:
after a permissions mod changed what they may use. The tree goes out in
the next server tick, with no player's state swapped in, so the helper
works from any server hook, the player's own included. Nothing calls it
without a mod.
Unproven: not yet built or run (handed to the hooks-all integration branch for the build and proof).
native_player_command_level(player, name, command, level) is heard in
Game::guest_command after native_player_command, before the server checks
the command: level comes in as the player's own and becomes the level this
one command runs at (GuestCommand.permission), so a permissions mod can
grant /gamemode to a player of level 0 or refuse a command to an operator,
as Paper's VanillaCommandWrapper does with minecraft.command nodes. A mod
command with a permission node falls back to this level. Unchanged, the
command runs at the player's level, as before.
Unproven: not yet built or run (handed to the hooks-all integration branch for the build and proof).
NativeCommand::new(usage).permission(node) gives a mod's command a node, as
Bukkit's plugin.yml permission: does. The server then asks
native_has_permission(player, node, level), the command's level as the
default, both before it puts the command in a player's command tree and
before a player's typed command reaches native_perform_command, so a
permissions mod can grant it below that level or refuse it to an operator.
Without a permissions mod the level decides, as for a command without a
node; a dedicated server's console runs every registered command as before.
Unproven: not yet built or run (handed to the hooks-all integration branch for the build and proof).
native_player_commands_sent_v2(player, name, names, names_hidden) is heard
right after native_player_commands_sent, at the same times, with the root
commands the player's level hides (those a level 4 operator would get) in
names_hidden. A root a mod moves into names is sent with its subtree, as
for an operator of its level, so a command a permissions mod grants
completes and highlights in the player's chat box (Paper's
PlayerCommandSendEvent after a passed permission check). v1 keeps its
signature and firing point. Without mods nothing is granted and the tree
is unchanged.
Unproven: not yet built or run (handed to the hooks-all integration branch for the build and proof).
The hook native_permission_check(player, node, default_level, result) lets a
permissions mod (a LuckPerms port) say whether a player has a permission
node; the first mod to set result decides. The helper
native_has_permission(player, node, default_level) asks it, for every mod
and for the server, and falls back to the player's operator level against
default_level when no mod answers, as Bukkit's Permissible.hasPermission and
NeoForge's PermissionAPI.getPermission do. Without a permissions mod every
answer is the operator level, so nothing changes for unmodded servers.
Unproven: not yet built or run (handed to the hooks-all integration branch for the build and proof).
CI has no fontTools: the import failed before main() could print the
usage, so the new test saw a traceback (verify failed).

Use the entity position for the special ambient caller and cover adult and baby natural events through the real Mob tick and recording route.

parity-main: natural_spawn first fails at f6a9444de (#10416), of 182 merges
since 66f3981f5. The spawn start heights it produces differ from vanilla 26.3
by up to tens of blocks (chunk/10 monster: vanilla y 99, Horizon 62), so
players would see mobs spawn at the wrong heights. Reverted until the change
passes the natural_spawn harness.

Written by hand from a scratch resolution seeded with this lock: rusqlite,
libsqlite3-sys, fallible-iterator, fallible-streaming-iterator, hashlink,
vcpkg, yaml-rust2, arraydeque, gif, weezl, color_quant, snap. Existing
entries keep their versions; chrono gains serde and mysql_common gains chrono.
To confirm: cargo metadata --locked must not want to change it.
#10304 gave mob_to_nbt a fifth argument after the raid observation's call to it
was written, and the two merged without a conflict.

The bundle's fragments carry no mod_api entry: session A adds them in one
step (add_mod_api.py, which takes a cancel: &mut bool parameter for the
cancel contract). So interact_entity_v2's claimed and
right_click_block_v2's canceled are named cancel; they act as before.
Not built yet.
native_living_incoming_damage_v3(victim, victim_uuid, kind, attacker,
attacker_uuid, direct, damage_type, amount, cancel) fires everywhere v1
fires (health::HURT_SERVER), right after it with the amount v1 left and
the same cancel flag. It adds a player victim's UUID, the causing entity
where v1 leaves 0 (a mob's attacker, a player's melee, the synchronous
attack in progress as living_knockback_v2 falls back to), a player
attacker's UUID and the direct entity. Players are noted by entity id as
each guest's turn starts (game/native_damage.rs, only while a native mod
is loaded), since the hit carries ids only and no Game.
Not done here, as the plan asked: a &mut self host (the victim is
borrowed out of the game inside Mob/Player/Dragon hurtServer, behind the
HURT_SERVER fn pointer) and Bukkit's modifier breakdown (the reductions
run after the hook in horizon-world's living_hurt and Mob::hurt_server).
Sentinel (attacker matched within 500 ms), Wanted, HuskSync and
CombatLog (an id-to-player map each tick) need the names.
Not built yet.
native_kick(player, reason) disconnects a player with a Text reason in its
colours and translations (Adventure's Player.kick(Component)), through
Hub::kick as /kick does, so the log line and native_player_kicked follow.
It is queued and runs at the tick's end with the mod messages
(flush_native_net), so it works from any server hook, the kicked player's
own included; today a port sends a raw Disconnect and then runs /kick with
one plain line.
Part of #10461.
native_resource_pack_status_v2(player, name, pack, status) is an additive
version of native_resource_pack_status with the answered pack's id
(Bukkit's PlayerResourcePackStatusEvent.getID), so a mod's own pack's
answers are told apart from the server's. In play it is heard just before
v1, which keeps its signature and firing point. The answers to the
server's own pack given during configuration, which the connection thread
handled alone, are kept (lan::Configured::pack_answers) and heard once the
player has logged in, right after native_player_logged_in. The connection
answers the packets exactly as before.
Part of #10461.
rusqlite 0.41 (bundled + cache, no default features) reads SQLite files such
as a Bukkit plugin's .db; yaml-rust2 0.13 (no default features, safe Rust)
reads and writes config.yml; gif 0.14 and snap 1 are small and pure Rust;
mysql gains chrono for DATETIME columns. All optional, nothing builds them.
Cargo.lock not yet updated.
tick_server_spans calls native_server_tick_timed with the pass's wall and CPU time and merged spans (TickSpan, re-exported from spans::Span) before handing them to the report. Spans are switched through tick_profile::want_spans by who wants them (HORIZON_SPIKES, horizon-report, a mod), so a mod and a report no longer turn each other's spans off. tick_profile keeps a mod's mob cost sums apart from the report's (two bits, two maps), so both can sample at once; calibration stays the report's. Fragment server_tick_timed.
While a mod turns counting on, the network threads keep each framed and read play packet's id and body size in the connection's Outbox (io_pool Conn::frame and Conn::read, behind one relaxed load of a static switch, capped at 65536 each way); the server tick's end hands them to native_server_packets per player and way. Off (the default) nothing is kept and the hook never fires. Fragment server_packets.
native_hurt_entity(dimension, target, amount, damage_type, attacker)
hurts a mob or a player of the level as LivingEntity.hurtServer with
damageSources().mobAttack(attacker) does, the way /damage <target>
<amount> <type> by <attacker> goes: cmd_damage's hurt is moved unchanged
into damage_target, which both call. Returns whether it hurt; false for
another dimension, a target that is neither a mob nor a player of the
level, a missing attacker or a non-finite amount.
Sentinel's own damage (damage set, workaround damage, lightning weapon)
today runs a damage command by UUID.
Not built yet.
native_send_resource_pack(player, id, url, sha1, prompt, required) sends
ClientboundResourcePackPushPacket with the mod's own pack id (Bukkit's
Player.addResourcePack), checked against the packet's limits (hash at most
40, URL at most 32767 characters); native_pop_resource_pack(player, id)
sends ClientboundResourcePackPopPacket for one pack or, with None, all
(removeResourcePack). Both go through native_send. A decline still kicks
only when the server's own pack is required, as vanilla's
handleResourcePackResponse does.
Part of #10461.
native_player_register_channels(player, name, channels, register) hears
the names a client registers (minecraft:register) or unregisters
(minecraft:unregister), NUL-separated as Bukkit's and Fabric's clients send
them; vanilla reads neither (Bukkit's PlayerRegisterChannelEvent). What a
client registered during configuration, which the connection thread
dropped, is kept (lan::Configured on Joined) and heard once right after
native_player_logged_in; a message in play is heard as it is handled, with
the player's state swapped in, and then goes on as before. The helper
native_player_channels(player) lists a guest's channels
(Player.getListeningPluginChannels). At most 128 names of at most 256
bytes are kept per client.
Part of #10461.
names.rs: #10328 landed on main; its NameTagLayouts frame now wraps this
PR's frustum-culled collect_name_tags, both test sets kept.
scoreboard.rs: #10098 added the hide_gui argument to tab_list::visible;
the early visibility check here passes !self.ui.hide_gui too.

native_block_redstone(dimension, pos, old, new) is asked, as Bukkit's
BlockRedstoneEvent, when a button is pressed (hand or arrow) or let go by
its release tick, a lever is pulled, or a pressure plate's weight check
changes its signal. A mod may change new; one equal to old keeps the
component as it is, and a held button or plate is asked again at its
next scheduled check. The seam is LevelAccess::redstone_change in
horizon-world (default: leaves the signal), which GameLevel forwards on
an authoritative level. Wire, torches, diodes, observers and the other
sources are not heard yet.
CoreSMPEssentials part B holds its power rods' component on without the
2-tick re-set that leaks a 1-tick off pulse. Test (not run):
a_level_can_keep_a_lever_as_it_is.
Not built yet.
Bukkit's Player.setCompassTarget: Hub.compass_targets by UUID while the player is on; default_spawn sends the target in place of the world spawn wherever it is sent (join, respawn, level change). Without a target the packet is unchanged. Helper-only fragment compass_target.
Bukkit's BossBar.addPlayer/removePlayer: a NativeBossBar (mod_api) by player UUID in BossState, offered to that viewer by boss_events_for, so publish_boss_bars sends Add/Update/Remove as for the world's bars. Unmodded servers keep an empty map. Helper-only fragment boss_bar.
Vanilla's ServerLevel.sendParticles(player, ...) and Bukkit's Player.spawnParticle: within 32 blocks, 512 with force (overrideLimiter). Replaces the hand-built LevelParticles (dust id hard-coded) of plugin ports; same options and checks as GameLevel::native_send_particles. Helper-only fragment send_particles_to.
Bukkit's Player.playSound for plugin ports, which sent a raw ClientboundSoundPacket through native_send. Queued in game/native_player_fx.rs and sent at the tick's end with the hub back, so it works from any server hook; helper-only fragment play_sound_to.
Sentinel's native attacks (its default) call Mob.doHurtTarget for the
body. Horizon's do_hurt_target needs the goal's world, and its player is
whichever guest the mob sees, so the port injected a goal and wrote
LanHost.mob_players to bind the body to its target. native_mob_attack
runs do_hurt_target from any server hook with the target guest's view as
the mob's player (a new lan_guest_view, the single-guest form of
lan_guest_views), then hands the hits on that player to the guest and the
rest to handle_mob_events, as a mob's tick does. Helper only: unmodded
servers never call it. Part of #10461.
The Team review (kacpherek) on #10382: groups filled in arrival order
under a 32 cap hid a late UseItemOn burst behind other players' moves;
count > 1 dropped 69 players sending one 6-9 ms use each; and one slow
event hid the rest of its group. Groups are now one per packet kind (a
bounded set) with the time of their short events only (the slow ones
are noted on their own), and each names the player who spent the most
of it: "213 x UseItemOn under 10 ms each; most from Steve: 140 of
them, 700.0 ms".

native_remove_entity(dimension, id) also removes projectiles (arrows,
tridents, snowballs, eggs, pearls, fireballs, wind charges, llama spit,
shulker bullets, firework rockets) as /kill does (kill_target), and a
server player's fishing bobber, as Entity.discard: the bobber of the
player in place, or outside a guest's turn any player's of the level
(remove_server_hook in fishing.rs). Displays, markers and interactions go
as before. Sentinel's arrow cleanup and CoreSMPEssentials part B's power
rods need it.
Not built yet.
Citizens' Navigator and Sentinel walk their bodies to points and
entities, stop them, ask whether they still walk and aim their heads.
Horizon offered this only to a goal (Mob::nav_move_to with the goal's
world), so ports injected a goal that read intents from a global map, or
moved bodies in straight /tp steps through walls. native_mob_navigate,
native_mob_follow, native_mob_stop, native_mob_navigating and
native_mob_look_at call the mob's own navigation and look control
(PathNavigation.moveTo, stop, isInProgress, LookControl.setLookAt) from
any server hook, for a mob of any loaded level, with the world its goals
see. Helpers only: unmodded servers never call them. Part of #10461.
native_move_entity turns only the entities Horizon keeps without
simulating them, and native_teleport_mob takes no rotation, so NPC ports
turned their bodies with execute .. rotate or tp .. facing every few
ticks. The helper is /rotate (Entity.forceSetRotation) for an entity of
any loaded level, with an optional head yaw (setYHeadRot) for a mob.
Helper only: unmodded servers never call it. Part of #10461.
native_entity_data_to(viewer, entity, values) is a typed shortcut of
native_server_packet for ClientboundSetEntityDataPacket: the entries one
guest is about to get for one entity, changeable for that viewer alone, so
a mod can show one player glowing to one viewer without touching the
server's own flags (TAB's and Essentials' per-viewer glow, which resend
their own packets on a timer today). Heard just before native_server_packet
for the same packet. Switched on by native_watch_entity_data, which decodes
that packet only. EntityDataValue is horizon_protocol's entity_data::Value.
Part of #10461.
native_fishing_hook_landed(player, hook, dimension, block, face) hears a
server player's flying fishing bobber meeting a block on its way, and
each tick it lies on one (on the ground as the tick began or ends: the
block under its centre, its top), as Bukkit's ProjectileHitEvent for a
FishHook. It is heard at the end of FishingHook.tick with the bobber back
in place, so a mod can remove it there. hook_block_hit keeps its result;
a sibling hook_block_hit_at also gives the block and face.
CoreSMPEssentials part B starts its power rods from the plate, button or
lever the bobber lands on; native_projectile_impact leaves bobbers out.
Not built yet.
NativeLevelStats counts a level's loaded and forced chunks, block entities and ticking ones (BlockEntities::ticking_len), and its entities (players included) and block entities by type. The entity list reuses the selector walk (level_candidates, now pub(in crate::game)) with a parked level swapped in as /execute in does; block entity types come from the block (lan::chunks::block_entity_type), which the enum's variants cannot tell apart, so this replaces the planned BlockEntity::type_id(). Fragment level_stats.
A stage plugin keeps its actors by UUID and moves, changes or removes them
in whatever level they are in; Horizon's entity handles reach the level in
place only, so ports ran tp/data merge entity by UUID on the console.
native_entity_by_uuid finds the entity (players included) in any loaded
level and returns its dimension, id and type; native_merge_entity_nbt is
native_entity_merge_nbt for a named loaded level. Helpers only: unmodded
servers never call them. Part of #10461.
native_lod_column(dimension, column, seed, flat, column_out) is asked
for each column GeneratorWorker::lod_grid, surface_sample and
surface_column sample. A mod whose native_chunk_generate builds that
chunk answers the column's blocks (and its biome) with
column_out.replace, and the far terrain shows them, with the top, the
water over it and the spans derived as vanilla's sample derives them,
instead of vanilla's noise until the chunk generates.
Vanilla's far sample is computed first and only replaced when a mod
answers: without a mod, one empty call per column and the same columns
(#105).
native_player_fish_v2(player, name, state, hand, cancel) is
native_player_fish with the rod's hand: the hand the cast or reel-in uses
(Bukkit's PlayerFishEvent.getHand), and for a bite the hand holding the
rod, main hand first as FishingHook.shouldStopFishing looks. Asked right
after the unchanged v1 hook with the same cancel flag. CoreSMPEssentials
part B sees off-hand stasis and power rod casts.
Not built yet.
native_server_packet(player, packet, cancel) hears each play packet the
server is about to send one guest, decoded, a broadcast once for each
player, where PlayerSender::send hands it over (ProtocolLib's and
PacketEvents' outgoing listeners; NeoForge and Bukkit have no event).
A changed packet is encoded again, a canceled one is not sent. Nothing is
decoded or copied until a mod calls the helper native_watch_server_packets:
until then each packet costs one relaxed atomic load. The hook is a free
function the game sets once (lan::conn::SERVER_PACKET), as player_move is.
Part of #10461.
Both helpers were refused for any level but the one in place, so a mod
spawning from native_server_tick (where no level is defined) or into
the Nether from the Overworld's tick could not, and Stage-style ports ran
`execute in <dimension> run summon` instead. The named level is now put
in place for the call and put back afterwards, through the same
enter_command_level that `execute in` uses (npc_in_level in the new
native_npcs.rs). A level not loaded is still refused. Unmodded servers
never call these helpers, so nothing changes for them. Part of #10461.
native_right_click_block_v2(pos, face, hand, canceled) is
native_right_click_block with the hand that clicks (NeoForge's
PlayerInteractEvent.RightClickBlock.getHand), asked right after the
unchanged v1 hook with the same flag, once per hand tried. A cancel does
what a v1 cancel does. CoreWG's guard refuses an off-hand flint and steel
or bone meal; today it sees the main hand only.
Not built yet.
Keeps both test modules (mixed_size_tests, undrawn_terrain_tests) and
has_terrain with #10502's doc and undrawn flag after sizes_differ.

native_tick_times() returns the last 100 tick durations at vanilla's getTickTimesNanos indices (tick n at n % 100); native_tps() the ticks a second over one, five and fifteen minutes (Bukkit's getTPS), measured between recorded tick ends in FixedStep::record. Helpers only, fragment tick_times.
native_interact_entity_v2(entity, kind, hand, stack, claimed) is
native_interact_entity with the hand that clicks (NeoForge's
PlayerInteractEvent.EntityInteract.getHand), asked right after the
unchanged v1 hook with the same claimed flag: a click v1 claimed is not
asked again. Once per hand vanilla tries, so a mod claiming the main hand
hears one event per click (Citizens' click events and commandtrait
hands, CoreWG, CoreSMPEssentials part B).
Not built yet.
native_chunk_generate(dimension, chunk, seed, flat, chunk_out,
generate) is asked on the generation workers for every chunk, after its
biomes and structure starts and before the noise (Bukkit's
ChunkGenerator.generateNoise). A mod sets the chunk's blocks through
NativeProtoChunk::set_block and answers NativeGenerate::Replaced with
the shouldGenerate* flags: vanilla then runs only the surface rule, the
carvers (on a superflat level too), the structures and the features it
asks for. set_biomes and clear_structures work with either answer.
Left at Vanilla, nothing changes: the hook is one empty call per chunk

The crossbow hit, trident hit and trident hit_ground sounds come from the same
Entity.playSound as the arrow hit (AbstractArrow.onHitBlock / onHitEntity,
ThrownTrident.onHitEntity), so they take getSoundSource(), NEUTRAL, too; the
name-based guess put them on PLAYERS.

A saved chunk's zlib stream was inflated by a new Decompress, 8 KiB at a
time into a stack block, each block then copied onto the output, which
grew by doubling from empty. Now each thread keeps one inflater, reset
for every chunk, and a whole stream that fits is inflated straight into
the output, reserved at about eight times the stream (a chunk's usual
ratio) and never past one byte over the limit. Any stream that fails
(damaged, cut short, over the limit) is decoded again the old way, so the
error and what the output keeps are exactly as before. A new test
compares both on whole, cut and damaged streams around every limit.
A failed region restores its originals before the error comes back, so
the world is whole: blocking the start then took a server down for a
corrupt chunk record. Only a recovery that cannot finish stops it now.

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 NativeChunkSnapshot of a loaded chunk of an open level (block states,
WORLD_SURFACE heights, noise biomes, the fuzzy biome zoom's cell) that
shares the chunk's sections copy-on-write and can be read on another
thread, with native_block_map_color, native_biome_name and
native_biome_tint to draw it. Replaces the engine internals a web map
reads today. No behaviour change. Part of #10461.
native_attribute(uuid, attribute) gives an attribute's base value and its
value with every modifier (Bukkit's AttributeInstance.getBaseValue and
getValue); native_set_attribute_base sets the base as
/attribute .. base set does; native_set_attributes loads a saved
attributes list onto the player as vanilla's AttributeMap.load reads a
player's file. A lower max_health caps the health, and the client gets
UpdateAttributes from the tick's sync. Nothing calls them without a mod.
Unproven: not yet compiled or probed live (build queue); the integration branch tests it.
native_effects(uuid) reads a player's effects as NativeEffect { id,
amplifier, duration, ambient, particles }; native_add_effect gives one as
vanilla's LivingEntity.addEffect (Bukkit's addPotionEffect), so a weaker
or shorter one waits under it; native_remove_effect takes one off as
/effect clear does; native_set_effects replaces them all, what a mod
restoring a saved player needs instead of writing PlayerEffects into the
hub's guests. The client gets UpdateMobEffect with the ambient and
particle flags from the tick's sync. Horizon keeps no hidden-icon flag on
an effect, so none is offered. Nothing calls them without a mod.
Unproven: not yet compiled or probed live (build queue); the integration branch tests it.
native_player_food(uuid) reads a player's food level, saturation and
exhaustion; native_set_player_status(uuid, health, food, xp) sets each
that is given, as Bukkit's setHealth, setFoodLevel, setSaturation,
setExhaustion, setLevel, setExp and setTotalExperience. The write goes
through the player's turn as /kill and /effect reach a player
(for_player), so their client gets SetHealth and SetExperience with the
tick's sync. Health is capped at the maximum; 0 or less kills as /kill
does, with "<player> died" (Bukkit's setHealth(0), LivingEntity.die with
the generic source). The mod's food is not heard as the player's own
change (native_food_level_changed) outside their turn. Nothing calls it
without a mod.
Unproven: not yet compiled or probed live (build queue); the integration branch tests it.
The helper native_player_compound(uuid) gives a player's compound as the
server would save it now (players/data/<uuid>.dat, playerdata::player_tag),
vanilla's ServerPlayer.saveWithoutId: what a mod keeping players in step
across servers (a HuskSync port) stores, instead of calling player_tag on
the hub's guests itself. None inside a player's turn, where their live
state is out of their record, and for a player not on. The new module
native_player_state.rs holds this group's helpers. Nothing calls it
without a mod.
Unproven: not yet compiled or probed live (build queue); the integration branch tests it.
What a Horizon server sends a 26.2 client (accept_older_clients) now carries 26.2's
registry ids: tags, block states, entity, block entity, block, attribute, sound and
particle ids, and items and components through the existing Way::Down writers, which
now leave out components the client lacks. A creative slot or container click from the
client is read with its ids up.
generate_registry_id_adapter.py --substitutes writes, from both versions' data
reports, a stand-in for each 26.3 entry 26.2 lacks (poplar as birch, wool and concrete
slabs and stairs as stone ones of the same shape, ...); what has none (the cushion
entity) isn't sent. v26_2_ids.rs is regenerated with it.
Part of #10404.
native_profile_by_name(name) gives the id and name, and
native_profile_by_uuid(uuid) the name, of a player who is on, else one
in a dedicated server's profile cache (usercache.json): vanilla's
GameProfileCache, Bukkit's getOfflinePlayer without its network
lookup. They ask no profile service and make up no offline player;
UserCache::find_by_name reads without changing the cache. native_player_head
names a player who is off from the cache too. Ports parse
usercache.json or ask Mojang themselves today.
A proxy that balances players between servers has to know, before it sends
one, how many players a server has and whether a login would be refused as
full. transfer-status answers with counts only: the players placed, held and
expected, the hand-overs under way, the places the player limit counts, the
limit, and whether the server is full. It names no player, changes nothing
and writes nothing to the log, since a proxy asks it often. Like the player-*
requests, it is refused while [transfer] is off.

frame::contents made a new ZlibEncoder for every packet above the
compression threshold, which allocates and clears zlib's window and hash
tables (some 300 KiB) each time. A thread-local Compress, reset before each
packet and driven with the encoder's own calls (the input unflushed, then
finish), writes the same bytes. A new test checks them against a fresh
encoder for bodies from 256 bytes to 300 KiB, in both orders.
GameRenderer.renderLevel gives LevelRenderer.render shouldRenderSky false
while a boss bar makes world fog (the Ender Dragon's), so the frame is only
cleared to the fog colour. Horizon drew the End's sky box behind the island
during the fight. fog::sky_pass_skipped now holds vanilla's conditions:
LevelRenderer.addSkyPass's (lava, powder snow, blindness or darkness) and
the boss fog.

native_set_inventory_slot(uuid, kind, slot, expected, new) puts a stack
in any slot of a player's inventory or ender chest, armour and off hand
included, if it still holds exactly `expected`, and returns what was
there (Bukkit's setItem). native_take_stacks(uuid, slots) takes exact
stacks out of the given slots, all or none. Both are checked like
native_move_stack and work live or on the player's file. Wanted by the
InvSee, AdminKit and Wanted ports (armour slots, splitting, stakes);
Wanted edits LanHost guests directly for this today.
Unproven: not yet built or run on a server (handed to the hooks-all integration test).
Part of #10461.
native_set_inventory(uuid, kind, slots, selected) replaces a player's 41
inventory slots or 27 ender chest slots (Bukkit's
PlayerInventory.setContents), live or in their file like
native_inventory. For the inventory it sets the held hotbar slot, empties
the cursor and the 2x2 crafting grid, and sends a player on the server the
whole inventory at once. The HuskSync port writes Guest fields directly
for this today.
Unproven: not yet built or run on a server (handed to the hooks-all integration test).
Part of #10461.
native_block_place(player, name, stack, pos, state, cancel) is heard
where BlockItem.place has found the position and the state and checked
survival, before anything is set (Bukkit's BlockPlaceEvent, NeoForge's
BlockEvent.EntityPlaceEvent). A canceled placement is a failed one: no
block, no use, no swing, and the client gets its blocks and inventory
back. The position and state come from the existing dry run
(Behaviours::placement_state). Ports cancel placements today by claiming
native_use_item_on, which also stops doors, chests and the item's other
uses.
Unproven: not yet built or run on a server (handed to the hooks-all integration test).
Part of #10461.
native_inventory_drag(player, name, window, kind, slots, cancel) hears a
guest's quick craft in their own inventory or a vanilla menu once, at its
end, with the kind and the window slots the client dragged over (Bukkit's
InventoryDragEvent). A canceled drag's end is handled like a canceled
click: the drag ends empty and the client's prediction is answered with
the server's slots and cursor.
Unproven: not yet built or run on a server (handed to the hooks-all integration test).
Part of #10461.
native_inventory_click(player, name, window, slot, button, mode, cancel)
hears a guest's click in their own inventory or a vanilla menu they have
open before any handler applies it (Bukkit's InventoryClickEvent). A
canceled click becomes a drag start of no type, which every menu takes as
resetQuickCraft and nothing more, so nothing moves and the client's
predicted slots and cursor are answered with the server's, as for any
click the server refused. Drags and a mod's own menus are not heard.
Wanted by the HuskSync and Essentials ports (data lock, freeze).
Unproven: not yet built or run on a server (handed to the hooks-all integration test).
Part of #10461.
native_player_launch_projectile_v2(player, name, stack, cancel) is heard
where ProjectileItem.use creates a snowball, egg, ender pearl or a mod's
thrown item, before the projectile exists (Bukkit's ProjectileLaunchEvent
for a player). A canceled throw is a failed use: nothing is thrown, used
or put on cooldown, v1 hears nothing, and the guest's client, which took
the item at once, gets its inventory back. Wanted by the HuskSync port's
data lock (no ender pearls while locked).
Unproven: not yet built or run on a server (handed to the hooks-all integration test).
Part of #10461.
native_player_textures(uuid) gives the textures property (value and
signature) of a player who is on, as their player list entry carries
it (Paper's Player.getPlayerProfile). native_player_head(uuid) gives a
minecraft:player_head whose profile holds the player's id, and their
name and skin when they are on (Bukkit's SkullMeta.setOwningPlayer).
Ports look the current skin up at the session server today, or build
heads with a name-only profile.
native_player_pre_login(player, name, address, defer) runs on the
connection's own thread once the session service or the proxy has named
the player and before the server's own checks (Bukkit's
AsyncPlayerPreLoginEvent). A mod that needs time, a permissions or
inventory load, or may refuse, pushes a Receiver<Result<(), Text>> onto
defer and answers from any thread: Ok lets the player on, Err refuses
them with the reason. The login waits for every answer, 20 s at most in
all; a missing or dropped answer refuses with a plain Disconnected.
Today such loads start in native_player_login, where a database failure
cannot refuse the player.
native_set_profile_property(player, name, value) sets or removes a
property of an online player's profile (Paper's Player.setPlayerProfile);
native_refresh_player(player) shows them again at the end of their
level's pass: everyone who sees them gets their list entry anew and
their entity again, and the player is respawned in place into the same
level with all data kept (Paper's hidePlayer/showPlayer plus the
respawn), so their own client draws a new skin too. Both work from any
server hook, native_server_tick included. They replace the raw HEAD
injection on Game::flush_native_net that edits Guest.properties and
sends the player info itself.
native_player_profile(player, name, properties) runs on the
connection's own thread once the server has let a player in and before
it sends LoginFinished. A mod may change, add or remove the profile's
properties (a skin's textures): the player's own client and every
player list get the new ones (Velocity's GameProfileRequestEvent,
Paper's PlayerProfile at AsyncPlayerPreLoginEvent). It replaces the raw
HEAD injections on lan::conn::login_and_configure and
Game::lan_guest_joined that skin and Floodgate ports use today.
The helper native_player_permission(player) gives the permission level of a
player on the server or joining it (0 to 4, ops.json's for an operator,
PlayerList.getProfilePermissions). It works inside native_player_login for the
player that hook hears, whose level the hub set on admitting them, so a login
gate that lets operators through needs no ops.json of its own. The hook's
contract is unchanged.
The helper native_send_custom_payload_to_player(player, channel, data) queues
a ClientboundCustomPayloadPacket on any namespace:path channel outside
horizon: (at most ClientboundCustomPayloadPacket's 1 MiB) for one player's
client, vanilla or Horizon, sent at the tick's end with the mod messages, so
it works from any server hook. Bukkit's Player.sendPluginMessage.
native_custom_payload_from_client(player, channel, data) hears a guest's
ServerboundCustomPayloadPacket in play on any channel that isn't Horizon's own
(horizon:mod_net, horizon:quiet_commands, horizon:lod), which the server drops
today. Like mod messages it waits for the tick's end, with the hub back, so
every helper works; it is heard from a dead player too, as vanilla's
handleCustomPayload doesn't look at health. Horizon's own channels are handled
as before. The client side is #6774.
With proxy forwarding on (forwarding.secret, offline mode, not the integrated
server's own player) the handshake's host is read with Short.MAX_VALUE as its
limit, as Paper does behind a proxy, so a proxy's data after the host (a
Floodgate player's, often longer than 255 characters) no longer drops the
login. Without forwarding the limit stays vanilla's 255; it is the only string
read with that limit.
native_handshake(address, host, intent, cancel, reason) is a free function in
horizon_client_lib::lan::conn, called on the connection's own thread for each
network connection's handshake, before the server acts on the intent. A mod may
rewrite the host (a proxy's data after it, Floodgate's, included) or refuse the
connection: a login or transfer is disconnected with the reason, a status ping
is closed unanswered. Wired through NativeClientHooks like player_chat. Nothing
changes without a mod.
native_creative_slot_v2(player, name, slot, stack, cancel) is an
additive version of native_creative_slot with the whole ItemStack put in
the slot (none for an emptied one), components included. It is heard
just before v1, which keeps its signature and firing point and hears
nothing of a packet canceled here.
Part of #10461.
native_item_dropped_v2(player, stack) is an additive version of
native_item_dropped with the whole ItemStack thrown, components included
(enchantments, unbreakable, attribute modifiers...), heard just before
v1, which keeps its signature and firing point.
Part of #10461.
native_item_picked_up_v2(player, stack, thrower, position, canceled) is
an additive version of native_item_picked_up: the whole ItemStack with
its components, the item entity's thrower UUID (none for block and mob
drops) and its position. It is heard just before v1, which keeps its
signature and firing point and hears nothing of a pickup canceled here.
Part of #10461.
native_player_spawn_location(player, name, dimension, position,
rotation) is heard once per join after the saved data is loaded (or a
newcomer's spawn found) and before the level is chosen and the world is
sent (Spigot's PlayerSpawnLocationEvent). A mod that changes them places
the player there, in that level, with no teleport afterwards. An unknown
dimension or a non-finite value leaves that part unchanged.
Part of #10461.
native_player_hurt_by_player(attacker, attacker_entity, victim,
victim_entity, source, damage_type, amount, canceled) names both players
by UUID and network entity id, and how the hit came: melee, sweep, or the
projectile's entity type (arrow, spectral arrow, snowball, egg, a mod's
thrown type). It is heard where native_living_incoming_damage is, at the
victim's hurtServer past its guards (pvp rule and teams allow it, victim
not invulnerable or dead), and just before it: changing the amount
reaches v1, canceling skips the hurt and v1 alike. The PvP call sites
name the hit in a thread-local scope that hurt_server reads.
A snowball or egg does zero damage, where vanilla's Player.hurtServer
stops: it is heard there with amount 0 and nothing the mods set applies.
Thrown tridents hurt no players in Horizon yet and are not heard.
Part of #10461.
native_player_logging_out(player, name) is heard when a placed player's
connection is gone (lost, kicked, quit) but before their menu closes and
they are saved and removed (Bukkit's PlayerQuitEvent): they are still in
their level and listed in native_server_players. No state is swapped in;
the hub is back in self.lan for the call, so the UUID helpers and
native_run_command reach them. A death a mod causes there (`kill <name>`)
is died at once (death message, drops, native_player_died), since the
leaving player gets no further tick to die in; they are then saved dead.
Not heard when the server stops, where native_player_logged_out already
tells with them still listed. Unmodded servers are unchanged: the death
step only runs when the hook took the player from alive to zero health.
Part of #10461.
native_log_line(level, thread, message, line) hears each message
written to logs/latest.log, on the log's writer thread after the file
has it, so the thread that logged never waits on a mod and a Discord
console bridge needs no tailing of latest.log. line is the text as the
file got it. The logger calls it through logging::set_line_hook,
installed before the log opens; trait mods are reached through
NativeClientHooks. A callback that panics is not called again, so its
own panic line can't loop.
Refs #10461
native_console_line(source, line, cancel, replies) hears each line the
dedicated server's console is about to run, before vanilla's commands,
the dedicated-only ones and mods' registered ones: source is console
(typed on the console, or sent by horizon-server as the console) or
rcon. Set cancel and it does not run; replies are logged as the
console's feedback, so they also reach the RCON or horizon-server
caller. Until now native_perform_console_command only heard commands
a mod registered, so an audit mod could not see ordinary console
commands (Bukkit's ServerCommandEvent / RemoteServerCommandEvent).
Refs #10461
A mod limits one player's view distance below the server's: only that
player is told its radius (SetChunkCacheRadius) and is sent and tracks
chunks within it; native_player_view_distance reads it. The guest's
distance is ChunkMap.getPlayerViewDistance under the limit; with no limit
(every unmodded server) it is exactly as before. Part of #10461.
A level's world border bounds as the server enforces it, for a web map's
border line and a pre-generator's border selection. Vanilla 26.3 keeps a
border per level (ServerLevel.getWorldBorder, each level's
data/minecraft/world_border.dat); Horizon keeps one for every level, so
the helper answers the same bounds for each level until that is fixed.
No behaviour change. Part of #10461.
native_force_chunk only reaches the level in place, so a mod could not hold
a chunk of the Nether or the End from a server-wide hook, and a level not
open yet never ticked: a pre-generator for those levels never advanced.
native_force_chunk_in takes the dimension; a level held this way opens at
the next server tick and ticks while held. Unmodded servers hold no mod
tickets, so nothing changes for them. Part of #10461.
native_player_tick_pre() runs once a tick for every living player in the
world, at the top of their ServerPlayer.tick, before their digging, item
use and cooldowns. native_player_tick (API 31) already ends the same tick.
It fires in tick_guests after the checks that skip a dead player and one on
a server trip, so the pair brackets the same players. Single player's own
player is a guest of its internal server.
The fragment player_tick_pre.json labels it PlayerTickEvent.Pre (side
server, not cancellable) for horizon-port-pack events. 23 of ATM10's mods
listen to it.

A composite program writing two colortex buffers was skipped whenever their
`size.buffer` lines differed, even when one relative size and one pixel size
came to the same size (`0.25 0.25` and `320 180` at 1280x720). Iris 1.11.7
draws it (a probe pack of ours: texel (100, 50) of both reads 100.5, 50.5 and
texcoord 0.314, 0.281).
Sizes of one kind that differ still skip the program as the pack loads. A mix
of the two kinds is kept, and the pass is skipped only at render sizes where
the buffers it writes resolve to different sizes.

37 of ATM10's mods listen to the parent ModConfigEvent, which hears the
three events NeoForge's config page documents under it: Loading, Reloading
and Unloading. config_loading, config_reloading and config_unloading answer
them, so the parent now counts as hooked rather than as another phase's:
93 of 326 names, up from 92.

NeoForge's documentation describes one event under two names. 1.21.1's
"Registering Additional Models" (ModelEvent.RegisterAdditional, one
ModelResourceLocation per model) is "Registering Standalone Models"
(ModelEvent.RegisterStandalone, a key and a baker per model) from 1.21.5 on.
Both versions use the same sentence, and the example method is still
registerAdditional. standalone_models (API 151) answers it, so the 47 ATM10
mods that listen to it now count as hooked: 92 of 326 names, up from 91.

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.

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.

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).
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.
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.
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.

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).
`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 `(`.
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.
The Players tab's second button now opens RealmsInviteCodesScreen: the count in the
title, the subtitle, a row per code with its expiration (or Never), Copy / Edit / Delete
per row, and Create. RealmsEditInviteCodeScreen edits one code: its active flag, the
seven InviteCodeExpiration choices (a click on the slider track picks the nearest — this
screen has no drag event yet), Copy to the clipboard (a new Outcome::Copy the title
turns into Action::CopyText), Delete, Done and Back.
RealmsClient gains inviteCodes (GET api/v1.0/invite/codes?realmId={id}),
createInviteCode (POST .../invite/codes), updateInviteCode (POST .../update) and
deleteInviteCode (DELETE .../delete/{code}), all on the invite-code service with the
token in x-mojangauth, with InviteCode's DTO. The existing redeemInviteCode now goes
through the same helper. An existing expiration reads back as the closest of the seven
choices (InviteCodeExpiration.closestTo).

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.

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.

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).

Round-two review finding: a long invite's identity kept only the host's
addresses when it had any. Two friends on other networks behind the
same private address and the fixed direct port (25580), each reached
through a relay, shared one NativeWorldId. The relay's address and
nameplate now stay beside the addresses; neither secret takes part.

Review findings on the session state helpers:
- NativeClientState.screen read remote_loading(), which leaves out the
portal loading screens because they draw no panorama blur, so a
minimap drew over them. A connection's screen is now one predicate,
remote_screen_up(), which remote_overlay draws by too.
- Every long friend invite showed as the same "Friend's world", so two
friends' worlds shared one NativeWorldId and a mod's per-world data.
A friend's world is now friend: and the invite's public part (the
host's addresses, else its relay nameplate), never its secret.

A minimap or waypoint mod can now read what it needs through stable
helpers instead of Game's fields, on a server's client and in single
player alike:
- native_client_state() gains screen (NativeScreenKind: playing, chat,
death or another screen), debug_screen (F3), world (NativeWorldId:
single player's save folder or the server's address, for per-world
data) and sleeping_pos (the bed, LivingEntity.getSleepingPos).
- native_biome(pos): the biome at a block as Level.getBiome picks it,
through BiomeManager's zoom.
- native_data_dir(mod_id) joins the helper catalog.
The window's connection remembers the save it joined through memory,
its own server thread's or P1's for a splitscreen seat, so the world
identity needs no mixin on open_integrated. A friend's world is named
as players see it, never by its invite secret.

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.

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.

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.
`Progress::done` on an advancement parsed from `{"criteria": {}}` (true, no
requirement groups to wait for) against one with a criterion (false), and
`Tree::automatic` over a tree holding both: only the empty one is listed, which
is what the load pass grants the rewards of.
Without the `done` change the first assertion fails at once
(`assertion failed: Progress::default().done(&empty)`), and `Tree::automatic`
does not exist to compile against.
`AdvancementProgress.isDone` loops over the requirement groups, so with no
groups at all it answers true: an advancement whose `criteria` map is empty is
finished from the moment the player's progress loads. `PlayerAdvancements.
checkForAutomaticTriggers` walks every advancement, and for those with no
criteria calls `award(holder, "")` - which finds no `""` criterion to grant, so
it neither toasts nor announces - and then `AdvancementRewards.grant`s it. The
rewards are granted again on the next load, because there is no criterion to
record them under.
Horizon required `!requirements.is_empty()`, so such an advancement was never
done and never paid out. `Progress::done` now keeps vanilla's shape (every group
satisfied, vacuously true with no groups), `Tree::automatic` lists the
advancements nothing can grant, and the progress load grants their rewards
through the new `grant_rewards`, which is the `AdvancementRewards.grant` half of
`award` split out so the toast and announcement stay with a real completion.
Scope, plainly: **no vanilla advancement has an empty criteria map** - all 1224
in the shipped data have at least one criterion - so nothing in the game's own
data changes. What changes is a datapack's: before this, an advancement it
declared with `"criteria": {}` could never be obtained and its rewards never
arrived, where vanilla hands it over on load.
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.

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.
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.

`StatsUi::key` as `Game::stats_key` calls it: the cycle wraps both ways, a
number picks its tab and is clamped to the last one, a key without Control is
left alone, an empty Items or Mobs tab is skipped (and not switched to by its
number), and a switch scrolls the new list back to the top.
`StatsScreen.keyPressed` runs `MenuTabBar.keyPressed` first: with Control
held, `TabNavigationBar` cycles the tabs on Tab and Shift+Tab (skipping a tab
that cannot be chosen) and picks one on the number keys, where
`InputConstants.Key.getNumericKeyValue` reads the main row's digits and the
keypad's. Horizon's statistics screen had no keyboard handling at all, so only
the mouse could change tabs.
`StatsUi::key` is that tab-bar key press: it reports whether the bar took the
key, moves to the chosen tab when that tab has rows, and starts that list at
the top as a tab press does. `tab_key` ports `getNextTabIndex` (a digit is
`floorMod(digit - 1, 10)` clamped to the last tab; Tab walks to the next tab
that can be chosen, one full turn at most) and `numeric_key_value` ports
`getNumericKeyValue`. `Game::stats_key` gives it the tabs that have rows
(`stats_tab_active`) and plays the tab's click when the tab changes, and
`Game::key_pressed` hands the statistics screen its keys.
native_health_hud_state described left_height and right_height as the ones
that place the selected item's name and the action bar. They are gone, and
the text no longer reads them.
The two calls in hud_fixture/kinds.rs still passed the 39 the old signatures
took. The probe compares against the vanilla client, which reads neither, so
nothing else changes.
cargo clippy --examples -p horizon-client-lib -p horizon-client -- -D
warnings is clean.
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.

The dedicated server and a LAN host decrypt each client's
ServerboundKey with the server's private exponent. That used
square-and-multiply, which multiplies only on the exponent's set bits,
with a data-dependent final subtraction in each Montgomery product, and
no blinding: a client controls the ciphertext and can time the reply,
the classic extra-reduction channel. The key is regenerated every start
(as in vanilla) and a recovered one still needs an on-path position,
but vanilla's JCE blinds this operation.
- Mont::mul subtracts n through a mask chosen from the overflow and
the borrow of t − n, never a branch (Big::sub_with_borrow,
Big::select). Every product takes the same steps.
- Mont::pow_secret: a square and a multiply for every bit of the
exponent's limbs, the product kept by a mask. RsaPublicKey::
apply_secret uses it; RsaPrivateKey::decrypt and ::sign call that.
Public-key verification and encryption stay on the faster pow.
- Big::from_be_bytes no longer skips zero bytes: it parses the private
exponent on every call, and the result is the same.
- Test: pow and pow_secret agree with a reference modular power, for
moduli near a limb boundary (the overflow case) and exponents with
leading zero limbs. The 11 existing RSA tests (OpenSSL signature,
known-key decryption, generated keys) pass unchanged.
No wire or parity change. Multiplicative blinding would be the more
complete fix once a modular inverse exists.

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.

LocalPlayer.isShiftKeyDown reads input.keyPresses, which LocalPlayer.aiStep

Minecraft.handleKeybinds runs before it, so a sneak pressed in the frame of

Hud.extractSelectedItemName is hud_overlays::ToolHighlight::draw and
Hud.extractOverlayMessage is hud_overlays::Titles::overlay_message; neither
row existed. map-check: 151 rows, no problems.
text_position_tests asks a ToolHighlight holding a stack and a Titles
holding an action bar for their draw calls at 320x240: the name's text top
is 240 - 59 (and 240 - 45 in a mode that cannot hurt the player), the action
bar translates to 240 - 68 with its text four pixels under that, and a
zeroed timer draws nothing. The font is built from no resources, as
chat_tests does, so the test needs no game assets.
Hud.extractSelectedItemName draws the name at guiHeight - 59, plus 14 in a
mode that cannot hurt the player, and Hud.extractOverlayMessage puts the
action bar at guiHeight - 68: both constants, which the health, food, air and
mount rows above the hotbar never move.
Horizon moved both up by max(leftHeight, rightHeight). That is 59 for a
survival player with armour, so the common case agreed by accident, but it is
69 with a second row of hearts and 81 for a player underwater on a mount, and
the two texts floated ten or twenty pixels above where vanilla draws them.
Both use the constants now, and HealthHud no longer keeps the heights: 26.3's
Hud has no such fields, only the locals of extractItemHotbar that the
contextual-info bar reads.
EnchantmentHelper.doPostAttackEffectsWithItemSource runs the victim's

the wearer by 1-5 and wears the piece by 2 (Unbreaking, breaking with
its entity event); the player's own Thorns doesn't answer a thorns hit,

The mace harness gets armored targets with Thorns and Unbreaking; new
lan_e2e check mob-thorns.

The note kept 0.1 at least until 0.2 leaves experimental, which would keep

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.

The port ran 0.1's grade on linear values, which darkened midtones by about
nine 8-bit steps. The soft shoulder and the saturation are a look written for
display values, so the grade now runs them on the encoded picture, while the
golden tint, the glow and the vignette stay on light. The pack drops its own
[tonemap]: Horizon's curve clips at white in SDR as 0.1's clamp did, and light
above white survives the grade for HDR. The captures now match 0.1 within
about 0.3 steps on average; what's left is the glow around light sources.

Through `ChatScreen::new` with `is_draft`, `key` and `draw` - the calls
`Game::open_chat` and `Game::chat_key_code` make: the draft's drawn text is
grey and italic, an edited draft and a box opened on ordinary text are not,
and the first Backspace on an untouched draft empties the box where an
ordinary box loses one character.
`ChatScreen` keeps the `isDraft` its constructor argument sets: `formatChat`
draws the text grey italic until `onEdited` runs, and `keyPressed` clears the
whole box on the first Backspace while it is still set. Horizon tracked the
draft (`Game::chat_draft`, `chat_draft_shown`) but opened the box as plain
text: `open_chat_method` knew whether the text was the draft and did not pass
it.
`ChatScreen::new` takes `is_draft` (`ChatScreen.init`'s `isDraft`), `edited`
(`onEdited`) clears it, `key` (`keyPressed`) clears the input on a Backspace
while it is set, `format` applies the draft formatter (`formatChat`, which
`ChatScreen.init` registers before `CommandSuggestions.formatText`) and
`resize` keeps it (`ChatScreen.resize` keeps the field).
`Game::open_chat` threads the flag from `open_chat_method`
(`ChatComponent.createScreen`); the in-bed wake-up
(`InBedChatScreen.onPlayerWokeUp`) and `Gui.openChatAndAddText` open plain
text, as vanilla does.
Broadcast unsigned say chat independently of feedback capture and keep the
command source display name. Add a two-client LAN regression for both
TrackOutput states and conditional-chain success.

Projectile.mayInteract asks mob_griefing for every owner that isn't a
player, and canBreakBlockInAdventureMode lets no non-player owner break
a block without can_break. An owner UUID that names a loaded armor
stand, boat or other non-mob entity was treated as no owner, so a
burning arrow lit TNT and campfires with mob_griefing off. The arrow now
asks the level for the UUID, as getOwner does.

These labels reach tr through a variable (the Launcher settings' slider rows, MODE_NOTES in
the server dialog), so the scan for tr("...") never asked for them and no table had them: they
showed in English in every language. Added to every table, in English, and translated in
fr.json.
The messages the Mods page shows after an install (a mod, a native mod, a data pack, a
modpack, a resource pack) and its "isn't set up" errors were built with format!, so they
stayed in English in every language: "Installed JEI for Horizon 0.1.0 into Horizon. Build to
play with it." on a French launcher. They now use trf with named holes. The 11 strings are
added to every table, in English, and translated in fr.json.
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).

With the switch, the game draws 0.2 packs ([frame] blend = "linear" is
still refused). A renderer made with a 0.2 pack picked draws a float frame
where the device can, else the 8-bit one; a pack picked or dropped later
runs on the frame there is, logged once. The renderer's material, sky,
weather, vertex and shadow entries decode a 0.2 stage's colours and encode
its results; scene_color, opaque_color and the water mirror are decoded
copies, shadow_color is float, and Frame's sky and fog colours are
decoded. The post chain ends in a window-size picture, and the pack's
[tonemap] (or Horizon's clip) draws it onto the frame, encoded at alpha 1.
With HDR on, HDR output lifts nothing of a 0.2 pack's world.

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.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
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.

The panel takes the Glass look from docs/design-system.md: the sunset with pixel ridges, frosted
plates, Geist and Bricolage Grotesque Heading, the theme's Hugeicons. What it already did gets a page
each in a sidebar (overview, players, console, backups, crash reports), and confirm()/prompt() become
in-page dialogs. The supervisor serves the theme's fonts and the mark; the CSP gains font-src 'self'.

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)).

## 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.

The port pipeline ([docs/version-ports.md](docs/version-ports.md), `tools/version_port.py`) detects a release, prepares it, diffs its classes against the pinned 26.3, regenerates the data-driven tables, runs every parity harness on it and writes a port report that becomes issues. The goal is as little human work as possible for any version, past or future. Detection and the first slices are merged; the scheduled agent that runs it every day isn't installed yet. Two versions in one build are out of scope.

#### A launcher screen readers can read
Screen readers read the launcher's buttons, lists and settings, and every part of it works from the keyboard.
<details><summary>Technical</summary>
Issue [#4537](https://github.com/horizon-rust/horizon/issues/4537): the launcher is GPUI (not Electron), so it exposes nothing to UI Automation, NSAccessibility or AT-SPI yet. Needs an accessibility tree from GPUI (an AccessKit bridge) and a role and label on each widget.

#### A visible beta label
A clear 'beta' label in the launcher and the game, so nobody is surprised that Horizon is still being built.
On a system Horizon has no download for, such as FreeBSD, the launcher offers to build the game on your computer, as it already does for native mods.
<details><summary>Technical</summary>
Issue [#4354](https://github.com/horizon-rust/horizon/issues/4354): when no release asset matches the platform, the launcher fetches the tagged source and runs the same pinned-toolchain `cargo build --locked` its native-mod builds use, with a warning about the time it takes. The build is unsigned, so the launcher marks the version as built locally.

No official build. Android was first closed as not planned, with touch controls, a mobile interface, packaging and loading the player's own assets all missing; the roadmap now includes it, iOS and a build for the browser as long-term goals. First pieces from contributors: `horizon-dualsense` compiling on iOS ([#1813](https://github.com/horizon-rust/horizon/issues/1813)) and helper-thread limits on Android ([#1751](https://github.com/horizon-rust/horizon/issues/1751)).
