🤖 Agent: The declaration passes horizon-mods' item check: max_stack_size 1 is the field (1..=99), and minecraft:equippable with only slot is a valid 26.3 Equippable. The #tag walk stops at 8 levels and reads only the carried jar's tags, so the oracle path and untagged items are unchanged.
🤖 Agent: Same diff as #12490, which I reviewed before its author closed it (its verify failure was a linker crash on a full-disk runner). A server's registry ids can no longer walk out of the resources folder (no ., .., empty or upper-case segments), predicate components get the same nesting guard as potions, and banner layer counts are bounded by the bytes left (2 per layer).
🤖 Agent: DebugEntries has load, set_status, toggle_status, enabled and save, and the F3+F6 editor is game/debug_options.rs, so the 'no editor' skip note was out of date.
🤖 Agent: PersistentEntitySectionManager refuses a UUID already in the level, so a duplicate inside a summoned tree stays a saved passenger under Passengers. Cost to watch: target_with_uuid scans every known UUID, now once per loaded entity with a UUID. I pushed #[ignore] on its second test, which unwraps HORIZON_TEST_RESOURCES like its ignored sibling (verify failed on it).
🤖 Agent: Columns decode on up to 4 workers and are delivered strictly in arrival order (seq). I pushed a fix: the attachments retain runs after the column's block entities load again, so a resent column keeps its block entities' attachments.
🤖 Agent: Builder::weather_layers and weather_layer are in horizon-world's environment_system.rs on main; environment.rs no longer has apply_weather, so the two rows point at the code that runs.
🤖 Agent: NonTameRandomTargetGoal: canUse needs an untamed mob, and the target keeps matching the selector (Turtle.BABY_ON_LAND_SELECTOR now checks !isInWater), so a baby turtle that reaches water is let go.
🤖 Agent: pack_lighting reuses one stack array (every row below h is fully written, the rows above refilled), the server's object states reuse the pooled States, and the guest turn skips the 5-stack clone when the gear is unchanged.
🤖 Agent: TraderLlama.maybeDespawn discards in aiStep, so a removed trader llama leaves the mob list in that tick (tick returns false); tame or persistent ones stay.
🤖 Agent: EntityEquipment.tick runs each equipped item's inventoryTick, so a stand's lodestone compass loses its target when the lodestone goes; only compass stacks pay the lookup.
🤖 Agent: AbstractArrow.tick: a stuck trident falls when the block at its position differs from lastState (the hit block) and nothing is within 0.06; startFalling's three nextFloat()*0.2F draws scale x, y, z in that order.
🤖 Agent: An unused invalid fill_layer in a selected pack now fails world preparation through the existing leaf codec, as vanilla's registry load does, instead of the dedicated server falling back to a flat generator; its capture harness (--kind/--output) runs by name only (pushed).
🤖 Agent: SpiderAttackGoal.canUse is super.canUse() && !isVehicle(): Mob.rider (a player on its back, set by mounts.rs and the remote/LAN vehicle paths) now counts beside extra.rider (a mob jockey).
🤖 Agent: HurtByTargetGoal.canUse returns false for a player's hit when universal_anger is on (checked after the timestamp, before the ignore classes, as vanilla); Who has only Player/Mob, so guests' hits take the same path.
🤖 Agent: MovementPredicate.matches as vanilla: per-tick velocity × 20, speed and horizontal_speed against squared bounds (a negative bound squares, as MinMaxBounds.Doubles does), vertical_speed on |y|, exact bounds with no tolerance; only an unmounted, unridden mob gets the snapshot, so other subjects keep today's false.
🤖 Agent: DefendVillage reads the villager's gossips by the selected player's own UUID instead of level.player_uuid, so a hated guest on a server is attacked and a hated host no longer turns the golem on a guest. I pushed a commit dropping a doc paragraph and a constant copied from another test file.
🤖 Agent: Merged main in (game.rs frame block and the add/add on horizon-polytone particles.rs, which matches main plus tick_source); the merged diff equals the last commit. Without a Polytone pack, polytone_animate/polytone_entity/make return at the first `let Some(registry)`, so the animate tick and spawn paths pay nothing.
🤖 Agent: Stands collide with shulkers, boats and a still adult happy ghast through Entity.collide's getEntityCollisions, with an obstacle grid built only when a stand moves, and Shulker.makeBoundingBox's lid lifts what rests on it.
🤖 Agent: Grindstone max_damage fix for main's menu_click 7998/8000 (#11434): writes the merged MAX_DAMAGE only when it differs from the item's own, as PatchedDataComponentMap.set does; unit test with the failing case
A carry without the oracle's facts declared every item that has no block as
a stick, so a mod's helmets and chestplates could not be worn. Items the
carried minecraft:{head,chest,leg,foot}_armor tags name (directly or through
the mod's own tags) now get minecraft:equippable with that slot and a stack
size of 1.

ObstacleGrid keeps main's reused scratch list (near takes &mut self) with
this branch's roots, near_except and huge-area path; the shulker keeps one
progress_aabb with a scale and bullet_origin is the centre of bounds_at;
the shulker shell tick and main's trader llama tick both run.

The row skipped the account check as a service. AccountStatus::allows_multiplayer
is documented as the method and the title screen enables its Multiplayer and
Realms buttons from it.
The row skipped the predicate, but save::dimension_is_vanilla_like is
documented as the method and its caller world_gen_unstable drives the
experimental-settings warning the note mentions.
The row skipped the predicate as a plain constant, but Slot::is_armor is
documented as EquipmentSlot.isArmor and read by slot_for and mob loot
replacement.
apply_weather is gone; the weather layers live in horizon-world's
environment_system: Builder::weather_layers adds one per attribute rain or
thunder changes, and Builder::weather_layer registers the entries weather
runs.
- Guard recursive `Component::read` calls in `skip::component_matchers`,
`gameplay::block_predicate`, and `v1_20_3::from_tag` with `Nested::enter()`
to prevent stack overflow DoS via deeply nested `CAN_PLACE_ON` / `CAN_BREAK`
exact component matchers, and tighten `banner_layers` pre-allocation cap.
- Validate registry and entry resource location segments in
`net::fill_known_entries` before joining paths and reading local files on
`Clientbound::RegistryData`.
- Fix data race UB in `horizon_threads::heap_census` (`slot` / `slot_name`)
by publishing `NAME_PTR` with `Release` and loading with `Acquire`, and
guard `CensusAllocator::alloc` / `realloc` against size addition overflow.
- Fix provenance UB in `horizon_threads::boot_paint` where an immutable
reference `&count` was passed as Win32 `AddFontMemResourceEx`'s mutable
`pNumFonts` out-pointer, and require `'static` font byte slices.
GrindstoneMenu.mergeItems sets MAX_DAMAGE to the larger of the two, and
PatchedDataComponentMap.set drops a value equal to the prototype's. Since
#11434 Horizon always wrote it, so merging two plain diamond pickaxes gave
one carrying max_damage:1561 (menu_click 7998/8000 on main).

`SpiderAttackGoal.canUse` is `super.canUse() && !isVehicle()`, and
`isVehicle()` is true for any rider. Horizon's `SpiderAttack` checked only
mob riders (`extra.rider`), so a spider with a player on its back began
the melee goal.
`HurtByTargetGoal.canUse` refuses a player's hit when the
`universal_anger` game rule is on, leaving that hit to the anger target
goals. Horizon's `HurtByTarget` always retaliated against the player, so
the rule changed the anger bookkeeping but not the direct retaliation.
🤖 Agent: Includes #12475 and #12476. Particle and emitter files are parsed with every expression compiled at load (a typo fails the load); nothing spawns them yet, so no runtime cost.
`NonTameRandomTargetGoal.canContinueToUse` re-tests the goal's
`targetConditions` while hunting, so the `Turtle.BABY_ON_LAND_SELECTOR`
(a baby turtle out of water) drops out as soon as the turtle enters
water. Horizon's `NearestTarget` only ran the base continue rules, and its
turtle filter never checked the water, so a wolf or cat kept hunting the
turtle.
🤖 Agent: Tooling only: save_roundtrip compares relative .dat paths as POSIX on every OS, so Windows' backslashes no longer make every file look renamed.
🤖 Agent: A surface rule's biome_is keeps vanilla's biomes and the pack's own; others (a "comment" entry, another mod's biome) are dropped and reported as lossy, since 26.3 refuses the pack over them.
Resource packs' custom particle types now run in the particle engine: the
initializer sets the particle up, the ticker moves, recolours and removes it,
its emitters spawn more, emitter values seed the particles they spawn, and
`limit` caps how many live at once. Block modifiers' emitters run from the
block animate tick, the way torches spawn flames; entity modifiers' emitters
run on the player each client tick (fog, dust and weather around them).
Expressions see the particle, the blocks and biome around it, the player,
the camera, the time and weather.
Model and GPU particles aren't drawn yet (model ones still tick and emit);
additive blending and rotation modes fall back to the plain translucent
billboard; entity emitters ignore bones.

entry the modifier replaced), as fallback_colormap's default "original".

🤖 Agent: HDR output now takes its gain from Hdr::draw_params instead of the removed mark-resolve lane; the change stays behind HDR, which is off by default, and frame_identity's test covers the no-pack path.
DefendVillageTargetGoal asks the villagers in the golem's box for the
reputation of the player (Villager.getPlayerReputation: the gossips
about that player's UUID). Horizon read one reputation per villager,
keyed by the level's own player, while each golem's goal looks at the
player it selects, often a nearby guest: on a server, a hated guest was
never attacked, and a hated host could turn the golem on a guest it
did not hate. The goal now reads the villager's gossips about the
selected player's UUID.

🤖 Agent: 1.21.1 biome effects move to 26.3's visual/audio attributes (colours as #rrggbb), carvers become the air list, and liquid carvers are reported as lossy.
🤖 Agent: A bare component in an item argument ([custom_data]) now fails with expected '=' as ItemParser's reader.expect does, instead of being ignored; !removals are unchanged.
🤖 Agent: Frustum select picks the same corner as the branches did (-0.0 >= 0 both ways) and the resident bounds are origin()'s arithmetic inline. I pushed a fix: upload order measured the camera section as floor(y/16) while keys count from the world's bottom, four sections off in the overworld.
🤖 Agent: Pack expressions are compiled at load and evaluated against the frame only when a pack's environment stack is loaded (pack.environments), so the vanilla path sets no frame and keeps folding constant layers.
🤖 Agent: Tooling only: loot_mine_location_block asserts its .local/h079/capture is new, so it fails at startup on the Mac runner after one run (#12405); it joins the other capture harnesses in named_only.

🤖 Agent: A block item whose block has another name (seeds) is carried with place_block; one whose block is left out stays in items_unknown. I merged main (both branches added a test at the same spot; both kept).

- Eliminate per-fluid-cell `Vec::new()` allocations in `mesher/fluid.rs` and

- Reuse `SectionMesh::packed` capacity and a thread-local scratch buffer in

A pack's attribute value or argument can be a scripting expression
(wiki "Environment Attributes"): fog that closes in with the rain and
with depth, a cloud height scaled from the value the layers before gave.
Each one is compiled when the pack loads and evaluated whenever its layer
applies, against what the frame sets: g (rain, time, day time, sky type,
dimension, render distance, moon phase), p (position, in water), c
(position, view distance in blocks), o (the camera's position, sky and
block light), r (random), v (the value so far, colours packed ARGB) and
the pack's config(id). Its result is the modifier's argument; one that
fails leaves the value as it was. A dynamic entry is never folded into
the base value, since it changes every frame.
Expressions are compiled with Arc instead of Rc so a pack's stacks can be
built on the loading worker.

A server that adds blocks_attacks and a long consumable to a sword (1.8
style sword blocking, #11817) sends both components in the stack patch,
which the client reads past. The client never started the use itself and
remote_tick_using dropped the use the server's living flags started on
the next tick, so the right click kept restarting the use and the input
slowdown flickered (GrimAC NoSlow).
Read the added components from the wire patch, as Item.use does from the
stack's components: Consumable.startConsuming / startUsingItem start the
use, Item.getUseDuration takes the consumable's consumeTicks (else 72000
for blocks_attacks), and the use is held until the button lets go or the
server stops it, as LivingEntity.updateUsingItem never completes a use on
the client (LocalPlayer.onSyncedDataUpdated keeps it running).

🤖 Agent: Same fixed [u64; 128] bitset with spill as the generator's (#12346): spilled words keep index 128 + offset, so the decorated chunk's biomes stay ascending, and the exact reserve avoids regrowth.
🤖 Agent: ClientLevel.tickEntities ticks in add order: after login (and after a respawn re-adds the player last) a mob added later pushes from where both ended the tick, so the push reaches the player's next move, which is what GrimAC's Simulation check expects.
🤖 Agent: client_mod_command is the chat-side mod hook; the SMP and other server mods use native_perform_command, so gating guests (lan_acting) out of it removes a level-0 path without touching server commands. The 4 GiB zip budget is per opened archive, and every Zip lives for one load.
🤖 Agent: PORTAL tickets are saved in chunk_tickets.dat with level and ticks left, reload on restart (prepareLevels), and do not expire while their chunk is still loading (canTicketExpire). I fixed the main merge: #12232's ticket fast path compared (chunk, level) pairs with this PR's PortalTicket (LAND-STOP: E0308); it compares (ticket.chunk, ticket.level) now.

Vanilla's ClientLevel ticks entities in the order they were added: after
login the player comes first, so a mob added later pushes it from where
both ended the tick, and the push reaches the player's next move. After a
respawn the new player is added after what the level holds, so those
entities tick before it. Horizon applied every mob's push before the
player's move, from where the mobs had just moved: walking into a mob
the server is pushing away tripped anticheats (GrimAC Simulation 0.02-0.04
on every push).
🤖 Agent: The spawner and trial-spawner lists keep their tick order and are taken around the client effects, so a client tick can't see a half-filled list.
🤖 Agent: Indexing the retained buffers by mob index is safe: nothing between the fluid loop and the rain loop adds or removes remote mobs, and an early return only loses the warm capacity.
🤖 Agent: The outline strokes keep their order (black then bright) and the custom PvP colour; both scratch vectors are bounded by MAX_OUTLINE_EDGES, so the retained capacity stays small.

the shulker up, as in vanilla.
- ArmorStand::shove makes up for Horizon ticking stands before mobs: a
stand that joined after its shulker gets vanilla's push-then-travel
ground and speed, one that joined before gets Entity.move's own.
- /data merge keeps a mob's and a stand's join order (Entity.load changes
the entity in place).
- A shulker a boat or a minecart picks up turns to AttachFace DOWN

time the lid opened.
- The lid sends MobEvent::LidPush; ArmorStand::shove moves each stand with
physics through the collision resolver. Mob::bounds_at gives a shulker
its makeBoundingBox, scaled and grown by getPhysicalPeek in float.
- Shulker.tick's own part (keep a face, ease the lid) runs without AI
too, and not for a shell that rides something (isPassenger).
- /data merge keeps a shulker's eased currentPeekAmount: Entity.load reads
only the raw Peek.
- A stand leaves out the boxes of mobs riding it
(isPassengerOfSameVehicle), so a stand carrying a /ride shulker rises.
- ObstacleGrid::near tests each box once when the query spans more cells
than there are boxes, and a stand's loaded Motion drops a component past
10 (Entity.load), so a huge Motion no longer stalls the server.
- A rider sits on a stand's float passenger point (1.975F widened).
- The harness adds a stand carrying a riding shulker and the lid opening
and shutting under the first stand.

ArmorStand.travel moves with Entity.move, whose Entity.collide adds
EntityGetter.getEntityCollisions: the entities that canBeCollidedWith the
stand (a living shulker, a boat, a happy ghast held still) stop it as
blocks do. Horizon resolved a stand's move against blocks and the world
border only, so a stand dropped onto a shulker sank into it, one dropped
onto a boat fell through to the ground, and one pushed into a shulker
went through it (#11877).
The stand tick now gathers those boxes once, when the first stand
travels (the same set that stops a dropped item, primed TNT or a falling
block), and passes the ones meeting each stand's box stretched by its
movement into the move. It runs in the server's tick, so single player,
LAN hosts and dedicated servers all get it.
The new stand_entity_collision harness drops stands onto a NoAI shulker,
a boat and the stone, slides one into a shulker's side, and compares
their Pos, Motion, OnGround and fall_distance with vanilla's tick by
tick. Without the fix 27 of its 198 records differ.

Packs set these const directives (ShaderDoc, OptiFine's shaders.txt);
Horizon always used the defaults (600/200/10/1 ticks). IterationT sets
wetnessHalflife 200 and drynessHalflife 50, so under Horizon its sky
stayed sunny for a minute after rain started (wetness rose 3x too
slowly) and stayed wet 4x too long after it stopped. The pack log now

draw_frame looks every visible tile up 3-4 times a frame and upload_lods walks them all; with

`Lod::dispatch_meshes` collected every active tile's ready samples into a new
map for each batch of mesh jobs (thousands of entries, rehashed as it grew):
5-10% of the main thread in flight. The map is now kept up to date where a
tile turns active or inactive and where its samples change
(`Lod::sync_sample`), in shards of 8 by 8 tiles behind `Arc`s: a batch copies
the shards' handles, and a change copies only its shard while a job still
reads it. Debug builds check it against the full gather on every dispatch.

draw_frame tests every far tile against the frustum each frame. A Tile held two SectionGpu

As 26.3 wrote crimson and warped forest vegetation: a simple block on nylium,

A BlockItem whose block has another name (Farmer's Delight's cabbage seeds
place `cabbages`, Supplementaries' way signs `way_sign_wall`) was left out
as "a block item without a block": 35 items over the 8 mods. It is now
carried with `place_block` naming its block when that block is carried
(vanilla's or one of the mod's declared ones), and left out as "its block
is left out" otherwise. That check looked the item's own name up in the
left-out blocks instead of its block's.

Food was left out ("no food template yet"): 82 items over the eight mods tried, most of Farmer's
Delight. 1.21.1's minecraft:food held what 26.3 splits into food (numbers), consumable (eating
time, on_consume_effects: one apply_effects per effect with its own chance) and use_remainder
(the bowl), as 26.3's golden apple and mushroom stew have them. NeoForge's cures are dropped, and an
effect of the mod's own is left out and reported (the game would refuse the item).

26.3 has no `block/template_farmland`: its farmland model is
`template_cube_bottom_top_indented` with `bottom`, `side` and `top`, where
1.21.1's template read `dirt` for the bottom and sides. A carried model on
the old template (Supplementaries' raked gravel) now names the new one with
its dirt as side and bottom, instead of drawing the missing model.
`minecraft:block/rope` (Supplementaries' bunting particle) is in neither
1.21.1 nor 26.3: not a rename, left as is.

A vanilla-type recipe with neoforge:conditions was kept as 1.21.1 wrote it, and 26.3 refused its
old ingredients: Quark's 1,466, most of Supplementaries'. The oracle's recipes are the ones whose
conditions passed (a mod's own conditions, such as config flags, are only known there): those
lose the conditions and are upgraded; the others go outside, as NeoForge left them out. Without
the oracle, NeoForge's own conditions are read against the mods ported along.

A mod's tag additions under another mod's namespace (data/create/tags/...) made it claim that namespace

🤖 Agent: Main fix: three lines a union merge brought back read a flag #12242 removed, so every command_exec-driven harness stopped with AttributeError (80 of 173 on #12344's run). Nothing else in the driver uses an undefined args attribute; the corpus builds its 161 groups.
#12242 removed --seed-sync-gaps-diagnostic and the block that read it.
The union merge that landed TheMrZZ's series (#12160) kept the block from

parity.py passes neither, so whenever --changed selects them they fail

TraderLlama.maybeDespawn discards an eligible llama in its aiStep when its
DespawnDelay runs out, so it leaves the level's entity list in that tick.
Horizon's countdown set m.removed, but ai::tick still returned true, so
the creature tick kept the llama in game.mobs until the next tick. During
that extra tick the next mob snapshot and the native leave bookkeeping
still saw it. Commands, the tracker and collisions already skip removed
mobs, so commands showed no difference.
The final return of ai::tick now reports a trader llama that its own tick
removed, and the creature tick drops it in that tick, as it does for a
despawned mob. The rest of the llama's tick still runs, and other species
are unchanged.

Port the service behind vanilla 26.3's friends list, without its screens:
- authlib's FriendsService over the discovery document: getFriends,
updateFriends, updateAttributes and updatePresence with the account's
bearer token, If-None-Match/ETag caches, Retry-After poll intervals and
the ten-second read cooldown (MinecraftServicesFriendsService).
- RemoteFriendListUpdateHandler's worker and state: one read a minute
(five in the background), a forced read after a successful action, the
result-code-to-state mapping and the cached lists.
- PlayerSocialManager's flags and accessors, with no screen using them.
- PresenceHandler: the sharePresence option picks the public status, the
client supplies getPresenceStatus each tick, and closing posts OFFLINE.
Minecraft's constructor decides whether the worker starts from the
account's friendsPreferences (UserFlag.FRIENDS_ENABLED /
ACCEPT_FRIEND_INVITES); title.poll_account now does the same after its
getAttributes answer. The overlay, the Online options switches and the
title/pause icon changes stay for later parts, so no player-visible UI
changes here. A joined Realm is carried to the presence status through
ServerData.isRealm's equivalent (Action::Connect.realm).
No new harness: the list and presence parsers, the state mapping, the
sharePresence levels and Retry-After are unit-tested.

🤖 Agent: Server configuration dialogs keep the panorama behind them (DialogScreen inherits Screen.extractBackground) instead of the flat 20/20/20 fill.
🤖 Agent: Includes #12355. A version picked in the Versions tab is kept (chosen-versions.json) until the player installs the recommended one, so the pre-build swap and the automatic updates no longer undo a deliberate pick.
Float writers already store colour and coverage. Remove the unused mark
resolve pipeline and shader, and keep the world scratch and parameters for
the tone curve and HUD composite that still use them.
Choose no-pack HDR gain explicitly without storing a frame lane. Keep the
uniform ABI and existing light arithmetic. TAA tracks baked gain and its
settings, preserves compatibility history when gain is off, and rejects
history when it resumes after a shader pack.
Use a non-float legacy oracle for writer tests and restore exact float,
OIT and visibility-buffer sessions in the identity harness. Preserve the
compatibility mark paths and the non-layered hand brightness sentinel.

🤖 Agent: Each stream now starts from 21 zeroed bytes (clear + resize, pushed): a bare resize left the previous stream's bytes past a short block, which the decompressor may read, so corrupt-stream checks could differ from a fresh buffer.
🤖 Agent: The retained page list is cleared after the shader pack's post passes (pushed): it keeps its capacity, but no longer holds clones of arena page buffers until the next pack frame, which would keep freed pages alive on the GPU once the pack is off.
🤖 Agent: Test-only: the smoothed-uniforms test steps PackInputs::frame_timing instead of backdating the wall clock, so a slow runner can no longer push centerDepthSmooth past its 1e-3 tolerance (failed verify on #12241 and #12311).
🤖 Agent: This head holds all 13 layers of TheMrZZ's series (12010 already merged; 11732 … 12133 below it), so landing it merges the rest. The top layer's own point: inside the hurt cooldown a hit is compared with `lastHurt` by its incoming amount, before armor and Resistance, and only the difference goes on to `actuallyHurt`, as `LivingEntity.hurtServer` does.
🤖 Agent: Stacked on #12330: landing it lands the chain. Only the float frame (HORIZON_HDR_FRAME=float) changes its alpha; 8- and 16-bit frames keep their pipelines and marks.
🤖 Agent: A spilled word keeps its index (128 + spill offset) in the chained iteration, so the ids stay ascending as with the Vec bitset; 1 KB on the stack per generated chunk.
🤖 Agent: Blender has no interior mutability (two OpenMaps and an Option, read only), so one shared empty Arc is safe for every chunk without old-world data, and non-empty blenders stay per chunk.
🤖 Agent: The ten handoff loaders share only the resource root and the parsed entity document, both immutable; a panic in a worker is resumed on the caller and Creative's error keeps its message, so startup fails the same way. No wall-clock number yet: the gain is the slowest loader instead of the sum.
A registry native mod's Versions tab lists each version's date and how it
fits the Horizon played (the fit line the trust text already uses), marks
the one the launcher would pick Recommended, and has Install on every
version but the installed one.
A version the player picks there stays as it is: no automatic update, no
offered update and no swap before a build, until the player installs the
mod again or picks its recommended version (mod-browser/chosen-versions.json).

smoothed_uniforms_take_iris_half_lives backdated the wall clock and let

PackInputs::frame_timing, which update() already takes as the frame's

Resource packs' Polytone biome and dimension modifiers now change the
environment attribute stack the frame draws (wiki "Environment
Attributes"): a dimension modifier's base group changes the dimension's
own entries, rain and thunder change the weather's, post_process adds a
layer after all others; a biome modifier's base group changes its target
biomes' entries (ids, #tags through the biome tags, patterns) and
post_process adds a biome layer after the weather. REMOVE drops an
entry; modifiers apply lowest priority first. Values that are scripting
expressions or colormaps are left for the next steps.
The stacks are built when packs load, only when a pack has modifiers, and
only the frame reads them: gameplay (sky darkening, the server's sun
angle) keeps vanilla's. Without such a pack nothing changes.
With such a pack on, its biome and dimension modifiers load and apply;
the environment_render and environment_system harnesses still match
vanilla.

🤖 Agent: LAN join and respawn packets carry the world spawn and its rotation, not the acting player's personal spawn, and /setworldspawn now updates connected players in every dimension (SetWorldSpawnCommand.setSpawn, PlayerList.sendLevelInfo).
Polytone packs keep most of their effects in pack overlays that a
polytone_condition turns on: a scripting expression over the pack's own
config entries (config('pack:fog') == 'ON', modOn('minecraft', range)),
or an object with require_config, require_mods and override. A pack's
config entries (assets/<namespace>/polytone/config_entries/*.json) are
now read at their default values, and an overlay with a condition is
active when it holds: an expression decides alone (packs pair it with
formats no version matches), an object only alongside the formats unless
it overrides them. Overlays without one work as before.

Environment now builds the dimension's EnvironmentAttributeSystem as
addDefaultLayers does: the dimension type's attributes, a biome layer for
every attribute some biome sets, the timelines its tag lists (in order),
and the rain and thunder layers where Level.canHaveWeather. The frame
samples it with the camera's Gaussian biome mix (the probe's order) and
the biome at the camera, so every attribute blends and changes with the
weather the vanilla way, not only the sky and fog colours, and the
hand-written timeline sampling, biome colour blending and apply_weather
are gone. Biomes keep their attribute maps for the biome layer.
environment_render now passes with no tolerance except one rounding in
Sky's light level fraction (was 218 inexact cases), and covers cloud
height.

Installing a registry native mod took its newest version, and a build

native_fit::best picks the newest version that builds on the Horizon

I merged main: #12255 already refreshes Health Boost in apply_death_effect and the trader's drink, so this PR's copies of those blocks were dropped and its test kept.
🤖 Agent: Piston block events and sculk charge cursors check the block-ticking ticket range (ServerLevel.shouldTickBlocksAt), not chunk ticking readiness, so they run in a freshly ticketed chunk; moving pistons still wait for readiness, as the oracle shows.

Choose float alpha storage independently of the no-pack HDR gain. Plain

getOffset divides the pointer's distance from the widget edge by the
widget height as floats: 26.3's bytecode is iload_3, i2f, iload_2, i2f,
fdiv before Mth.lerp and Math.round(float). The decompiled text without
the casts made widget_offset an int division, so a hovered widget's
tooltip stayed height - 3 below its edge until the pointer was a whole
height away, then jumped. On a 20 px button it sat up to 10 px lower than
vanilla's. The offset now follows the pointer as vanilla's does, rounded
with jmath::round_f32, and the test expectations are the values the real
26.3 MenuTooltipPositioner returns for the same inputs.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
The title screen's icon row (Friends, Language, Accessibility) drew its
sprites but no tooltip: the tooltip pass after the button loop only knew
Create World, Select World and Multiplayer. Vanilla gives these buttons a
Tooltip (CommonButtons.language and accessibility, FriendsButton while
friends are available), which WidgetTooltipHolder draws while the button
is hovered, placed by MenuTooltipPositioner and split at 170 px. The
accessibility onboarding screen builds its Accessibility Settings... and
Language... buttons with the same CommonButtons, so they lacked the same
tooltips.
Title::button_tooltip now names each screen's button tooltips, and both
the narration hints and the draw loop read it. The draw loop remembers
the hovered button's tooltip and draws it after the widgets (and after
the onboarding fade, which vanilla applies to widgets only) with the same
positioner (ui::tooltip_menu), before the toast so the toast stays on top.

AbstractChestBoat.remove and AbstractMinecartContainer.remove spill the
container through Containers.dropContents for every removal reason that
destroys the vehicle: the kill of VehicleEntity.destroy and a creative
hit's discard alike. That spill has no entity_drops gate; only the hull
item and chestVehicleDestroyed's second, empty spill follow the rule.
Horizon's damage path got both vehicles wrong. A chest boat dropped each
stack whole at its position with an item's own motion and a pickup
delay of 10, and never drew chestVehicleDestroyed's per-slot spots. A
container minecart scattered its contents only with entity_drops on, so
with the rule off (or from a creative hit with it off) the contents
vanished.
Both now share one Containers.dropContents helper (the /kill path used a
second copy): the contents scatter from a spot in the vehicle's block in
pieces of 10 to 30 with no pickup delay, before the ENTITY_DIE event and
before a boat's lead, as Entity.kill and AbstractBoat.remove order them.
The hull item and the empty spill still need entity_drops and a
non-creative hit. Every damage source (players, LAN guests, explosions,
lightning, /damage) goes through these two functions, so single player,
LAN and dedicated servers all get it.
The vehicle_command_damage harness now breaks a chest boat with /damage,
and a chest minecart with entity_drops off both by /damage and by a
creative player's hit, against the real 26.3 server. Each break must
leave the 5 diamonds inside the vehicle's block with no pickup delay,
and the 40 dirt as piles in that block whose counts add up to 40. A
gameplay test seeds the level random, breaks a chest boat and a chest
minecart, and checks that the random ends where vanilla's two
Containers.dropContents calls leave it (the empty second spill's draws
included).
The port map rows for AbstractChestBoat.remove and
AbstractMinecartContainer.remove point at the shared helper instead of
the removed /kill copy. The chestVehicleDestroyed row now says what is
left there: a player's hit on a container minecart angers no piglins yet.

🤖 Agent: The HDR float frame follows HDR, Smooth Gradients and the picked pack at once by rebuilding the renderer; all of it is behind HORIZON_HDR_FRAME=float, so the default path only pays one bool check per frame.
A shulker's bullet started at the centre of the shulker's block cell.
Vanilla's ShulkerBullet constructor starts it at
owner.getBoundingBox().getCenter(), and Shulker.makeBoundingBox grows
that box toward the open side by the lid's physical peek (times the
scale), so an open floor shulker fires from the top of its block
(#11974). shulker::bullet_origin now builds that box with
getProgressDeltaAabb at the shulker's scale, from the peek the goal
sees (the attack goal runs before Shulker.tick eases the peek, in both
games).
In flight, a bullet turned only before a full collision cube. Vanilla
asks Level.loadedAndEntityCanStandOn(next, bullet): the top face of the
block's collision shape, in the bullet's collision context, is full
(Block.isFaceFull). Top slabs, upside-down stairs, closed top trapdoors
and the like now turn it too, instead of the bullet flying into them
(#11970). collisions::projectile_can_stand_on implements the test, and
ProjectileWorld::solid becomes can_stand_on(pos, entity_y), since
scaffolding reads the bullet's height.
New harness shulker_bullet: the real ShulkerBullet constructor for all
six attach faces, every peek of an opening lid and four scales, and
loadedAndEntityCanStandOn over forty block states at four bullet
heights, compared bit for bit with the Rust probe.

Choose the frame format and HUD layering together. No-pack float HDR needs
the HUD layer, so devices without it keep the compatibility frame. A 0.2
pack still gets its float frame in SDR and HDR.
Rebuild when picking or dropping a pack changes the layering even if the
format stays float, so the renderer always has the layering a fresh start
would give it.

StackData::set_loot_component kept every component but trim in other,

Vanilla's ServerReconfigScreen is a plain Screen, not a
LevelLoadingScreen, so MusicManager.tick starts the MENU music that
getSituationalMusic picks once the player is gone. Horizon treated the
reconfiguration as loading (no player, no title, no credits) and stayed
silent until the next world; a reconfiguring connection no longer
counts as loading.
A Game test (prepared resources, ignored by default) puts a column
holding a biome id one past the table at the origin, reads it through
biome_at and biome_name_at (plains), then checks that a reconfiguring
client picks and starts the menu music and that the level probe after
it reads plains' music without a panic.
Biomes::name's doc now says that Biomes::get clamps such an id to the
last entry instead.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
A proxy that moves the player to another server reconfigures the
connection. Horizon keeps the last server's columns until the next
Login clears them, but Reconfigured already swaps in the next server's
biome table. When the last server had a biome the game lacks (added to
the table as id 67) and the next one does not, those columns hold an id
past the 67-entry table. situational_music still probed the level at
the origin during the reconfiguration, and biome_at indexed the table
with that id: "index out of bounds: the len is 67 but the index is 67".
Vanilla never reads that level: handleConfigurationStart calls
clearClientLevel, which nulls the player, so getSituationalMusic
returns the menu music. The music probe now asks Remote::has_level
(Login seen, no reconfiguration since) instead of logged_in.
The three places that indexed the biome table directly (biome_at for
music, ambience and custom skies, biome_name_at for random textures and
fishing, and /fillbiome's filter) now go through Biomes::name, which
names plains for an id past the table, as biome_at already did for a
missing column and Biomes::id does for an unknown name.

🤖 Agent: mob_died no longer resets scores at the death; vanilla does it in onDestroyed, so unloaded corpses keep them. The #12185 shulkers get fixed UUIDs so /scoreboard players list can match at all.
🤖 Agent: A new item's own random now makes its UUID (Mth.createInsecureUUID, the first two draws), then bobOffs, yaw and motion in that order, instead of a process-wide clock-seeded UUID; I merged main (the seed-sync gaps diagnostic this PR retires stays out).
🤖 Agent: Block contact scratch lists are kept on Game and restored on every Result path; I replaced extend(drain(..)) with append, the clippy error that failed verify (clippy -D warnings passes now).
`RealmsResetWorldScreen`'s Generate New World tile is enabled: it opens the Create
New World screen (`RealmsCreateWorldFlow.createWorld`), and its Create builds the
temporary world the upload packs instead of entering a local one.
- The tile returns the Realm, slot and reset kind to the title, which shows Create New
World with the default options. Create (`create_or_upload`) builds a `Level` from
those options (name, seed, game type, difficulty, cheats, game rules, feature flags
and data packs) and hands it back to the Realms screen; Back/Escape returns to the
configuration screen (or the list for a new Realm).
- `realms::create_temporary_world` mirrors `createTemporaryWorldFolder`: a temporary
folder with level.dat from `WorldData.createTag(null)` (no `singleplayer_uuid`), the
world generation and game rules, and the Create World screen's data packs moved into
`datapacks/`. No chunks: the Realm generates them.
- The upload runs the same `RealmCreationTask` → `SwitchSlotTask` → `packAndUpload`
chain as a local-world upload, with `RealmsWorldOptions.createFromSettings` (slot
name, game mode, difficulty, the game's version) and the hardcore setting. While it
runs `AlertScreen` (`mco.create.world.reset.title`) shows a Cancel; success returns
to the configuration screen, or plays the Realm just created
(`RealmsMainScreen.play`); cancel returns to the reset screen; a failure shows
`mco.create.world.failed`.
- `Level::write_upload` writes only the upload's files (no player file, weather or
clocks), with `singleplayer_uuid` omitted as `createTag(null)` writes it.

On the settings shell (Extras, Graphics), a value between `<` `>` could

They step at once rather than after A arms the row, as sliders do: A keeps
its step forward and there is no mode to find, and up and down passing over
a choice never change it. Up and down leave the row, and LB and RB reach the

Since #12110 a warden's client tick plays the heartbeat when its age is

🤖 Agent: An export that fails on a missing lib/tzdb.dat now names the Java to repair, matched only on the FileNotFound/NoSuchFile line for that exact path; other failures keep their message.
🤖 Agent: /loot and pack functions take the world's packs' loot tables: the id list comes from the loaded tables (root plus pack overlay) and is refreshed on /reload.
🤖 Agent: On the float frame every shader writes its own light; all of it sits behind the HDR_WRITE_LIGHT pipeline override, false on the default frame, so the SDR path compiles it out. Stacked on #12220 and #12247.

🤖 Agent: Death protection and milk removal clamp a mob's absorption to its remaining max_absorption (onAttributeUpdated), instead of subtracting 4 per Absorption level.
🤖 Agent: CPU terrain occlusion tests each section's padded mesh bounds instead of the whole 18-block cell, so empty space no longer keeps a hidden section drawn; sections without bounds keep SECTION_BOX.
🤖 Agent: Realms world slots draw their own pictures and template pages arrive page by page. Cost to note: the four 1024-tall slot pictures now live in the HUD atlas for every player, about one 1024-tall shelf of GPU memory; a follow-up should load them only while Realms screens are open.
🤖 Agent: /loot now applies set_name and set_components to its drops, as a chest's roll already did, and names each drop by its display name in the feedback.
🤖 Agent: Ports vanilla's timelines, keyframe tracks and all 32 easings into horizon-world with Java's float/double steps; nothing in the game calls it yet, only the two new oracles' probes.
🤖 Agent: One hdr_mark_light function serves the display and resolve passes; a GPU test checks it against the old code for every 8-bit mark and both easing modes.
🤖 Agent: The recipe_sources native hook lets recipe placement into a mod menu type's grid take ingredients from containers the mod names; stacked on #12240 and #12233, lands after them.
🤖 Agent: An unbounded arbitrary @e walks the joined families in insertion order (EntityLookup.getEntities), falling back to the old order if the walk fails; it builds one count map per such query, other selectors keep their path.
🤖 Agent: #minecraft:tick functions now run before the levels tick, so they read the game time from before the tick, and /schedule'd ones run in ServerLevel.tickTime once the clock has moved, as MinecraftServer.tickChildren orders them.
A mod answers `native_fishing_medium(dimension, hook, position, owner, medium)`
for a bobber that is flying or floating, not in water and not hooked to an
entity. `Some(NativeFishingMedium)` makes the spot a medium: in the block of
its `surface` or below, the bobber floats, waits, bites and is reeled in as
in still water; the catch rolls its `loot_table` (vanilla's
`minecraft:gameplay/fishing` when None) and `lure_ticks` replaces vanilla's
100 to 600 tick wait when set. It is asked on the server and on the clients
that draw the bobber, so both move it alike. No answer keeps vanilla, and
water is never asked about, so vanilla fishing is unchanged.
`horizon-ctl status` shows the hook's loot table. Fixes#12300.

With Improved Transparency on, the float frame's default lane no longer
stays marked: each see-through layer converts its own colour to light
(hdr_written) before it is weighted and accumulated, so the composite
lays light over the light behind it, as the forward passes do. Text,
shadows, weather and the border keep their source gain, as they do in
the forward passes; cracks keep their multiply blend outside the
accumulation, since it scales the light under them. Only a shader pack
keeps the frame marked now. The identity harness's float OIT session is

Vanilla's TestCommand.trackAndStartRunner adds a TestBatchSummaryDisplayer
holding the command's source; GameTestRunner.start runs the first batch
inside the command, and testBatchStarting sends
"Starting environment <env> batch <n>" with sendSuccess(.., true). Horizon
queued the line as a server console broadcast for the next tick, so `/test
run` answered only "Running 1 test(s)..." (world_test_def 94/96,
world_test_def_lifecycle 6 of its 10 differing records, as #11992 noted).
A runner a command starts now sends the line through that command's source
while the command runs (`feedback`). A test instance block's runner keeps the
server's source (TestInstanceBlockEntity.runTest), as do later batches, which
start from the tick.

Vanilla resets an entity's scores in ServerLevel.EntityCallbacks.onDestroyed
(Scoreboard.entityRemoved), when the entity is removed for good: a mob's body
twenty ticks after LivingEntity.die, never when it is unloaded. Horizon reset
them in mob_died, at the death. A mob killed in a frozen world and then
unloaded kept its scores in vanilla and lost them here, so a later
`/scoreboard players list` named 32 fewer holders (command_exec, after
#12185's shulker command damage case).
mob_died no longer resets them; score_destroyed_entities already resets every
removed entity's scores once a tick, and keeps an unloaded one's.
#12185's 32 shulkers had random UUIDs, which that list then named: Java and
Horizon could never print the same list. The case now gives them fixed
UUIDs, so the record is exact again.

With HORIZON_VISBUFFER=1, the float frame's default lane no longer stays

🤖 Agent: Block entities and scheduled ticks wait until their chunk's entities have loaded, as ServerLevel.isPositionTickingWithEntitiesLoaded gates them; the entities_pending set is cloned once per call.
🤖 Agent: A spawner's delay counts down without building a level view when no player is in range, the common case, and builds it only when it may spawn.
🤖 Agent: Decoration ranks are unique, so only chunks without a rank are measured and the queue is a heap that pops until the workers are full, instead of a full sort per update.
🤖 Agent: An item pushed out of a solid block takes its gravity step before the escape push (#12018), and the new command_exec case pins two ticks whose height and motion are exact whatever the random push speed.
🤖 Agent: The Graphics page describes its rows and the shell draws and drives them; I merged main's three-state GPU Culling into the new test helpers (focus_on, key), graphics_ui tests pass.
🤖 Agent: /setblock and /fill notify neighbours after all shape updates (BlockInput.place, ServerLevel.updateNeighboursOnBlockSet), so a wire beside a block that pops off ends as a cross; I merged main (fill's note-block normalisation kept) and marked the two resource-backed tests #[ignore], as the other HORIZON_TEST_RESOURCES tests are, since CI has no resources.
The visibility buffer draws only frames drawn flat, which frames without
a pack are by default only on Metal and some Intel drivers, so elsewhere
float_visbuffer compared the forward passes. It now sets
HORIZON_FLAT_DRAWS=1 and fails unless the game built the buffer. The

`IntegratedServer`'s constructor sets `setSingleplayerProfile(minecraft.getGameProfile())`,
and `ServerLoginPacketListenerImpl.handleHello` gives a login whose name matches that
profile the profile itself; the local memory hello names the account's profile id
(`Minecraft.handleClientLogin`'s `ServerboundHelloPacket(getUser().getName(),
getUser().getProfileId())`). The integrated server's owner, its gate/op entry and its
login are now the account's UUID; an offline start keeps the offline profile.
`MinecraftServer.saveAllChunks` saves with `saveDataTag(worldData,
getSingleplayerProfile().id())`: level.dat's `singleplayer_uuid` follows the owner on
every save. A world without one (a Realms download; `FileDownload.untarGzipArchive`
drops it) then loads the owner's `players/data/<account uuid>.dat` instead of starting
a new player.
Worlds older Horizon builds made name their player by the offline UUID everywhere:
level.dat's `singleplayer_uuid`, the player file and its `UUID`, and entity references
(`TamableAnimal`/`AbstractHorse`/`Projectile`/`AreaEffectCloud`/`EvokerFangs` `Owner`,
`ItemEntity`'s `Owner`/`Thrower`, `Fox`'s `Trusted`, `NeutralMob`'s `angry_at`,
`Leashable`'s `leash.UUID`). The first open under the account moves the player file to
the account's UUID (the newer of the two when both exist), rewrites level.dat before the
first session save, and rewrites each entity as its chunk loads, so the next save keeps
the account's UUID. A world renamed since it was made stays as it is: the old name its
offline UUID came from is not stored, so it cannot be identified.

`Entity.move(MoverType.PISTON)` uses up TNT's pending stuck multiplier
(without scaling the push), reads its fall for powder snow's top, adds
to that fall and resets it on landing, and applies the block speed
factor. `moveEntityByPiston` then runs `applyEffectsFromBlocks`, so
powder snow it is pushed into makes it stuck, and slime under it slows
it. Horizon did none of this, so in a chunk that does not tick
entities pushed TNT kept its motion in powder snow and on soul sand.

Block loot's `match_tool` (horizon-items) and the loot engine's

`compare_nbt` moves down to horizon-world (re-exported from nbt_path) so

A content mod's menu type may declare `"links": {"from", "count"}`: those
slots show the slots of block containers a native mod names each tick the
menu is open (`native_menu_links(player, menu, pos, links)`), in order, as
real slots of the menu. Clicks, shift-clicks and drags run on the server's
menu engine and move the containers' own items, a changed container is
saved and its comparators update, and the block entity never holds the
linked slots. Linked slots with nothing behind them hold nothing and are
left out of clicks, as a hidden slot is.
This is what a crafting station's side panel needs (Tinkers' Construct's

Primed TNT is an Entity in vanilla, so `checkFallDamage` adds each step
down, narrowed to a float, to its double fall_distance, which resets on
landing or in water and is saved and read and written by /data. Powder
snow uses that distance: over 2.5 it holds TNT on a 0.9-high top, and
otherwise TNT goes in and is stuck (0.9/1.5/0.9) like in a cobweb. The
stuck multiplier is used on the next move, which then zeroes motion.
Double and float lists in saved entity data now store -0.0 as 0.0, as
`DoubleTag.valueOf` does, so TNT resting on a block reads Motion 0.0d.

🤖 Agent: queued. The level in place reads its own saved `world_border` when the world opens, before any command, so a first `/worldborder set` is no longer overwritten later.
🤖 Agent: jukebox stop now captures was_playing before clearing j.playing, so the stop vibration fires once. On main merge 904b3036a, sculk, server_player_sculk, server_wool_vibration and mob_command_damage_vibration pass on playhorizon. command_exec's only 2 mismatches are main's gateway_item case (same 16819/16821 on bare main b13dbf068).
Ports net.minecraft.world.timeline and the keyframe machinery under it:
Timeline (clock, period, tracks, time markers, validateInternal),
AttributeTrack's codec (a modifier, override by default, and keyframes of
its argument), KeyframeTrack.validateKeyframes and validatePeriod,
KeyframeTrackSampler's looping segments and sampling,
argumentKeyframeLerp for every modifier, EasingType (cubic Bézier with
its Newton-Raphson and bisection solve) and all 32 Ease curves, with
Java's float and double steps (jmath, Mth's sine table). The layer stack
takes timelines as time-based layers that read their clock's ticks.
The new harness environment_timeline compares 3,464 cases with the pinned
client (every easing, the vanilla day, moon and early game tracks, and
synthetic and invalid tracks); environment_system now stacks the real
timelines between the biome and weather layers (36,000 lines).

- The world slots' pictures follow RealmsWorldSlotButton.State: the
minigame image (or presets/isles.png when it has none), the empty
frame, a slot's own template image, then the slot's panorama. The
atlas now keeps the four slot pictures (the three 1024-tall faces and
isles.png) at their own size: they were excluded as title/background
and presets, and even once let through were dropped by the 512-tall
GUI texture cap.
- WorldTemplate/WorldTemplateList read like JsonUtils' getStringOr,
getIntOr and getUriNullable: numbers read as their JSON text (some ids
and player counts are numbers, some counters are strings), and an
empty link is no link — the row icons are not drawn and no empty URL
can be opened.
- The template list fetches one page per job and appends it as it
arrives, chaining the next page until isLastPage or an empty page,
instead of waiting for every page before drawing the first row.
- The minigame list (RealmsWorldsTab.switchToMinigame) returns to the
Worlds tab on Back and Escape, not to a reset screen.
Tests: 2250 lib tests pass (71 realms), scoped clippy clean.

`TamableAnimal.TamableAnimalPanicGoal` passes a damage tag to `PanicGoal`:
`Wolf` gives it `#panic_environmental_causes`, while `Cat` and `Parrot`
keep the default `#panic_causes`. Horizon's `TamePanic` gated all three on
`fire_ticks > 0`, so only a burning pet panicked: a cat hit by a player or
a wolf freezing stood still where vanilla flees.
`TamePanic` now delegates to the `Panic` it wraps. The wolf's panic is
marked environmental (fire, freezing, cactus, lightning, lava); the cat's
and parrot's take any panic-causing damage.
`native_recipe_sources(player, menu, pos, sources)` lets a mod name
block containers (chests and the like, mod containers) that recipe
placement into a mod menu type's crafting grid may also take
ingredients from, after the player's inventory, as a crafting station
takes them from the chests beside it. No answer keeps vanilla's
placement.

Vanilla's Entity takes its UUID from the first two draws of its own random
(Mth.createInsecureUUID); ItemEntity then draws bobOffs and the yaw from it,
and the constructor without a given motion draws the motion last. Horizon gave
every entity a clock-seeded UUID when first asked, drew a new item's motion
from a fresh random's first draws, its bobOffs from the particle random and a
loaded item's from the level's, and left the yaw at 0.
spawn_item_own makes all four from one own random in that order and replaces
dispenser::new_item_motion at its callers. A loaded or summoned item makes its
UUID (unless the tag has one) and bobOffs from its own random, so summoning no
longer shifts the level's random. Primed TNT from a block takes its UUID from
its own random too.
The seed sync proof now reads those UUIDs, the drop's rotation and motion, and
a TNT kick after a summoned item: 8/15 before, 15/15 after.

Runs hand-built circuits and random "soups" of redstone components through the real
tick loop in vanilla 26.3 (the bench mod's client, no server, no EULA) and in Horizon
(horizon-ctl), in a frozen world stepped with `tick step 1`, and prints the first tick
where the blocks differ and which ones. Narrowing: --near/--drop reduce a difference
to a few commands.
- RedstoneDiff + ServerLevelTickMixin in the bench mod snapshot the box before the
first stepped tick and after each.
- `simulation blocks X1 Y1 Z1 X2 Y2 Z2` (horizon-ctl) reads the server's blocks, not
the window's replica, which lags the server by design.
- agent.rs: `blocks_json`, shared by `blocks` and `simulation blocks`.
Only blocks are compared; entities are recorded, not diffed.

Vanilla places a command's block with UPDATE_CLIENTS | UPDATE_SKIP_BLOCK_ENTITY_SIDEEFFECTS
(2|256), so Level.setBlock notifies no neighbour. The shape updates run inside
setBlock; ServerLevel.updateNeighboursOnBlockSet follows afterwards (for /fill,
after every block is in). Horizon placed with UPDATE_ALL (3), so the neighbours
heard of the block before its shape updates ran.
That is visible when the notice makes a block pop off: a comparator with nothing
under it breaks at its first notice and takes an attached wall torch with it. In
vanilla the wire between them had already connected to the torch, so it ends as a
cross; in Horizon the torch was gone first and the wire ended as a dot.
Found by tools/redstone_diff.py (two of 48 random circuits differed on vanilla
26.3 vs Horizon, reduced to four commands); after the change 144 random circuits
over three seeds match vanilla tick for tick.
- Behaviours::update_neighbours_on_block_set ports ServerLevel.updateNeighboursOnBlockSet.
- place_state takes `command`: setblock and fill use the vanilla flags; clone keeps
its own flow. The strict variants are unchanged.

The recipe book's place packet and Horizon's viewer transfer channel go

entity's grid, as a click does, with a ghost recipe when the items are

MinecraftServer.tickChildren runs the #minecraft:load and #minecraft:tick
functions before the world clocks and the levels tick; the Overworld's
ServerLevel.tickTime then raises the game time and runs the scheduled
functions due at the new time. Horizon raised the game time, the weather and
the day clock first, then ran the scheduled functions and the tick functions
after them, so a tick function read both clocks one tick ahead and a
`schedule ... 1t` from it waited a tick more.

🤖 Agent: removing an entity's chunk now drops its area-effect clouds too (breath_clouds.retain), and saves keep entity_base_tag's Entity fields. On main merge 8b583a15e, save_roundtrip, entity_nbt_boolean, orb_saved_uuid, stand_fall_save, conversion_water_save, mob_pickup_save and potion_effect_icon pass. command_exec's only 2 mismatches are main's gateway_item case (same on bare main b13dbf068).
LevelChunk.isTicking and ServerLevel.isPositionTickingWithEntitiesLoaded
also need the chunk's entity section loaded (areEntitiesLoaded). It loads at
the end of a level tick, frozen or not (PersistentEntitySectionManager
.processPendingLoads), empty sections too. A chunk that loads now waits for
the end of the level's next pass before its block entities (bells, conduits,
gateways and sculk blocks included), moving pistons and scheduled ticks run.
The command harness's readiness waits mark their chunks loaded, as the
vanilla oracle's do.

Every gassing geyser scanned every mob every 10 ticks, all on the same tick,
and every erupting one every tick. One grid of mob boxes is kept for the block
entity pass, until the mob list's next write; a geyser's own effects and
pushes move no mob, so the grid holds after them.
The mobs still get their effect and push in list order, and the gas reads
blocks only, so finding the reached mobs before any gets its effect changes
nothing.

A cave spider's poison bite or a bee's sting on a guest named the mob
nearest to where the hit came from in X and Z, ignoring height, so a zombie

🤖 Agent: queued. Four components (`provides_trim_material`, `provides_banner_patterns`, `can_place_on`, `can_break`) are now encoded in outgoing stacks with the synced registry IDs; anything unsupported drops the whole buffer, as before.
A game event posted outside the mob pass (a block placed, a door opened, an
explosion) looked through every mob of the level for the wardens and allays
that can hear it. The listener slots are now kept until the mob list is
written again (the previous commit's stamp), or another level's list is in
place.
Mob id lookups for game events, thorns and a hit's source go through the
mob index instead of a scan. A guest's melee event names the mob that

push_from_ticked_cart searched the cart list for the ticked cart twice and
copied it in and out whole. The caller knows its slot: the ticked copy is
swapped into the slot for the push, and only the pushed cart is copied back,
over the copy it replaced (clone_from reuses its buffers). Lava hurting a cart
looks there first too.
Without mods a push changes velocities and riders, never the list, so the
cart is still in its slot after it (a debug assertion checks). With native
mods loaded a mount hook can change the list: the copies and the search by id
stay. The loot roll stays with the ticked copy, as #11526 made it: it comes
off before the swap and goes back after.

EntityTypes.TNT is sized 0.98F with an explicit eyeHeight(0.15F). The box

A helper-only fragment adds `native_player_break_block(uuid, pos,

(ServerPlayerGameMode.destroyBlock): the player's checks, the
`destroy_block` hook, loot for the held tool and its enchantments, tool
wear, stats, exhaustion and experience. With `into_inventory` the block's
drops go to the player's inventory, the rest dropped from them.
The break now reports whether it removed the block, and a break nested in
another's hook keeps the outer break's own-event position. The acting
guest's spawn protection is kept for their turn so the helper can check
it while the hub is out of reach.

that uniquifier, the entity-id counter and the level's random in both engines,

masks this (PrimedTnt::tick_among restitutes), but in a lazy chunk the
velocity survives: a primed TNT pushed by a piston into a wall, ceiling
or slime keeps 0.4 / -0.8 / -0.8 instead of vanilla's 0 / 0 / 0.64.
Add restitute_piston after apply_push: compare the post-piston-limit
movement (limited) with the post-collision result (resolved) and, as
Entity.move(MoverType.PISTON, …) does, zero blocked horizontal axes,
zero or slime-bounce the vertical axis, and update on_ground. Covers
Player, Guest and every Entity kind including PrimedTnt.
Add unit test a_pushed_tnt_loses_velocity_into_a_wall (needs prepared
resources) asserting the TNT's vx is zeroed by a wall.

- Merge main.
- The owner switch from the offline UUID to the account UUID (integrated.rs,
lan/conn.rs, lan/playerdata.rs, net.rs, remote.rs) is left out: every world
Horizon made names its player by the offline UUID, so tamed pets and other
owner references would no longer know their player. It needs its own PR
with a migration.
- A tar entry part with a colon (a drive prefix or an alternate data stream)
would leave the world folder on Windows: skip it, with a test.

🤖 Agent: queued. When `/tmp` is shared the socket goes into a private `horizon-<uid>` folder, so another user on the machine can't connect to or squat on the control socket.
🤖 Agent: queued at a3fd3597f (main merged in; the draw now uses `random_source::entity()`). Thorns rolls in EquipmentSlot order from the wearer's own random, as `EnchantmentHelper.doPostAttackEffects` does.
🤖 Agent: queued. The defender now gets the Cooldown packet the server sets on the shield (`Player.disableShield`), so its client greys the shield out for the 100 ticks instead of letting it block client-side.
🤖 Agent: queued at 14bfb672f (main and #11750 merged in). UPDATE/REMOVE_MOB_EFFECT ids are renumbered for older clients; effects they don't know are dropped instead of showing as another effect.
🤖 Agent: queued. One cost to keep in mind: `stab_players_for` builds a Vec for every guest using any item each tick (shields, food too); small, but a follow-up could return early when the item is not a spear.
🤖 Agent: queued. Same check as `Camel.canCamelChangePose` (the standing box against the blocks above), and the test uses a block at y+2 that blocks only the 2.375-tall standing pose.
🤖 Agent: queued. The data file is written off the UI thread after `complete_assets`, and a stale one is dropped when the assets change, so a repaired install doesn't read an old index.
🤖 Agent: queued. Matches `LivingEntity.dropExperience`/`dropCustomDeathLoot`: experience and equipment follow `lastHurtByPlayerMemoryTime > 0`, while LAST_DAMAGE_PLAYER still needs the player to be resolvable, and the new test checks both sides.
🤖 Agent: queued at fee1085be (main merged in). A 1.21.3 pick_item now becomes the same container swap a 1.21.4+ client sends, so older clients keep middle-click in survival.
🤖 Agent: queued. The count goes up at the one `NetEvent::Packet` send in `conn.rs` and down at the hub's drain, so the 2× inbox cap bounds what a flooding client can queue between ticks without touching the hot path otherwise.
🤖 Agent: queued. The stop waits only with `[transfer]` on, and its 90 s bound stays under the supervisor's 120 s kill, so a proxy that never answers can't hang a stop. Built with 14 other PRs on main (pr_ready --quick green apart from known NixOS-only tests).
🤖 Agent: I moved the distance blend per pixel (it was per triangle through the flat hdr_code). Before/after screenshots and frame time are in my comment: the pack's GPU frame is 121.1 vs 122.0 ms on lavapipe, same within noise.
ResourceOrIdArgument decodes an inline value with the registry's codec
while the command is parsed, so a feature the ConfiguredFeature codec
refuses fails the parse: the command never runs, and an execute store
around it keeps its value. Horizon's parse accepted any compound for
minecraft:worldgen/feature and ran the codec only when the command
executed, which then failed and stored 0.
Where the server has its live features, the command registries now carry
a check that runs the same inline decode placement uses (the live
features' catalog and block bindings, through LiveFeatures::decode_inline),
without placing anything. A value it refuses fails the parse with
argument.resource_or_id.failed_to_parse. Without live features (a client,
or a server without the worldgen bundle) the parse is unchanged. The loot
table and every other registry keep their decode.
The message is the native codec's own (for example "invalid world
generation field: to_place"), not DataFixerUpper's text.

🤖 Agent: Follow-up to #8718. On main, lan_bot's older_clients_of_each_release_join_and_are_sent_chunks fails at 1.21.1 (the reverse step never adds 1.21.2's particle status to ClientInformation); CI misses it because the test returns early without prepared resources. With this it passes, as do all 440 horizon-protocol tests and, on the union, the particle harnesses block/emitter/entity/marker/native_client_particles, particle_providers, player_effect_amplifier and spell_ticks (8/8).
Each level reads its world_border SavedData when it is made
(ServerLevel.getWorldBorder), so a restarted server has the saved border
in place before its first command. #11016 gave each level its own
border. But world open reset the border of the level in place to the
default, and the saved file was read only later, in load_scoreboard (the
first tick's functions, or the first scoreboard use). A first
/worldborder get after a restart read the default, and a first
/worldborder set was put back to the saved size soon after.
World open now reads the in-place level's border with load_border, as
open_level does for the other levels, and load_scoreboard no longer
touches the border.

Mannequin extends Avatar extends LivingEntity; it is not a Mob.
Mannequin.addAdditionalSaveData always writes profile, hidden_layers,

A mannequin now reads main_hand and hidden_layers into the main-arm and
hidden-layer state it already had (a list with an entry that is not a part
hides nothing, as the codec's failed read), and writes all four from its
live state: the empty profile when it has none, the hidden layers in
PlayerModelPart order, its arm and its pose. It neither reads nor saves

renamed (recipes/, loot_tables/, structures/, advancements/,

The JSON stays 1.20's: a recipe whose result names its item as `item`

LivingEntity.hurtServer compares a hit inside the hurt cooldown
(invulnerableTime > 10) with lastHurt by its incoming amount, before

and stored the reduced amount. Under full Resistance every hit reduced to 0,

EnderEyeItem.use now fires the minecraft:used_ender_eye criterion with the squared horizontal distance to the located structure, matched against the distance bounds squared as MinMaxBounds.Doubles.matchesSqr does.
The End flash state now ticks on every client, so servers, LAN guests and single player show the sky flash and its light. Its weather.end_flash sound plays 30 ticks later ten blocks from the camera toward the flash, follows the camera, and is skipped under the credits.
Getting off a boat, minecart or mount whose block is in #minecraft:portals now takes the free-position branch straight up from the rider, as for a removed vehicle, instead of the vehicle's side dismount spot.
Shears now take the saddle off any #can_equip_saddle mob, not only pigs, and play the saddle's shearing sound item.saddle.unequip unless the mob is silent. A mount wearing horse or nautilus armor is left alone, since vanilla shears that body armor first.
A survival player's hit that breaks a chest boat with entity_drops on angers the piglins that see it, as AbstractChestBoat.destroy does through chestVehicleDestroyed.
A mob writes invulnerable_time while it has hurt immunity left and reads it back with a default of 0, so /data get shows it, /data merge sets it, and the immunity survives a save and reload.
time_since_rest now counts every tick the player is not sleeping, dead or alive, as ServerPlayer.doTick does; time_since_death still counts only while alive.
Items a server or datapack gives a camera_overlay now draw it in first person when worn in their equippable slot, and a carved pumpkin whose equippable was removed no longer blurs the screen.
Throwing a snowball, egg, ender pearl, splash or lingering potion or bottle o' enchanting awards the used statistic, as SnowballItem, EggItem, EnderpearlItem, ThrowablePotionItem and ExperienceBottleItem.use do.
A chestplate a server gives elytra wings now shows them and hides the cape, and an elytra whose equippable was changed or removed no longer shows elytra wings.
A frame broken by a player, an explosion or losing its support posts block_change after its drops, as ItemFrame.dropItem(level, causedBy) does, on top of the entity_die it already posted.
Armour a server or a command gives a different or removed equippable now renders with that asset, or not at all, and only in its own slot, on players, mobs and armour stands. The head layer draws a helmet item when its equippable has no asset.
EndermanTakeBlockGoal.tick posts block_destroy and EndermanLeaveBlockGoal.tick posts block_place, each with the enderman and the block state as context.
The first golem to open a chest half posts container_open with the golem as source, the last to close it posts container_close (incrementOpeners / decrementOpeners), and the openers recheck posts a sourceless container_close when the golems have walked off (recheckOpeners).
Filling a bottle from water now plays the fill sound at the player and posts fluid_pickup at the water block; both the water and the dragon's breath branch award the used statistic (BottleItem.turnBottleIntoItem), and collecting dragon's breath fires player_interacted_with_entity on the cloud.
Entity.move(MoverType.PISTON) ends in setOnGroundWithMovement on a server,
for every push: a sideways push clears the flag, and so does a free push
down. The ArmorStand-only repair in move_pushed becomes a trait method that
items, primed TNT and armor stands share.

`replace_word` lowercased the text to find the user's name in any case, and
used that copy whenever it had the same byte length as the text. Equal
lengths don't imply equal boundaries: `İ` (U+0130) grows from 2 bytes to 3
and `K` (U+212A) shrinks from 3 to 1, so a text holding both keeps its
length while its offsets move. A match then sliced the original text
mid-character and panicked.
Use the lowercased copy only when the two share their character boundaries.

EntityDataAccessor.setData keeps the entity's UUID around Entity.load of
the edited compound, and ExperienceOrb.readAdditionalSaveData reads its
Age, Health, Value and Count into the same orb. Horizon had no experience
orb case, so `data merge entity <orb> {Age:42s}` answered "Nothing
changed" and the orb kept its age.
The orb case decodes the edited compound with the existing orbs_from_nbt
and copies its saved fields into the resident orb, which keeps its
runtime id, join order, tick count and UUID. As Entity.load does, the
saved PortalCooldown is read while a live portal process stays. The
edited compound is kept like the other cases', so Tags follow it.
A falling block's Time is handled separately (#11424).

A resource pack's core/sky now draws the overworld's sky disc and its

ColorModulator and the sky's fog, the stars with their brightness, both
turned with the camera only. Without such a pack the sky draws natively.

LT + A on a crafting book recipe crafts it into the inventory: a tap makes
one, each further LT + A while one is in flight makes one more, and held past
the repeat delay it keeps going until a button comes up, the items run out
or the inventory is full. One request at a time, each waiting for the
server's answer; a result moves only with room for all of it as the client
last saw the inventory. A result that isn't the recipe's stops the craft with
nothing moved, and two seconds with no answer stops it with nothing more
sent. A refused LT + A (a carried stack, another recipe still finishing, not
allowed here) is plain A.
It's free in single player and on LAN worlds joined from the server list's
LAN entries; everywhere else, joins by address included, it waits for Quick
Craft on Servers. On any server but single player's own, placements keep
250 ms apart, under Paper's default limit on recipe placements (5 a second
over 4 seconds); on servers that need the option, every request also keeps
a tick apart.
On the crafting book LT changes the category as it comes up unless A was
pressed meanwhile; RT, and both triggers on the furnace books, change it as
they go down, as before.

Part of #11487. What the graphics screen has that the shell couldn't say
yet, for any screen that wants it:
- Undo over Done once a row changed something, putting back what the
screen says it changes (`Screen::undoes`, `Screen::undo`), from the
settings as the screen found them. Tab and the arrows reach it.
- A row's cost, a square and the cost in its colour after its name in the

does.
- `Shell::show` opens a screen at one of its pages.

- The shell keeps the rows it built and builds them again only when what
they read changes: the screen's stamp of its settings, a press or slide,
the search, the page, the size or the language. On Extras, a pad session
of 727 frames built them twice instead of 751 times.
- On a screen with no page list, Down from the search field goes to the
first row instead of Done, for the shell's keys and, through a declared
focus link, for the pad and the keyboard's focus.
- A row the list hides part of scrolls fully into view when the pad or the
keyboard focuses or presses it (AbstractSelectionList.setSelected), so A
presses it.

A server's client applied its effects' attribute modifiers itself, so it
slowed down as soon as ClientboundRemoveMobEffectPacket arrived. Vanilla's
server removes a Speed that runs out in ServerPlayer.doTick, after the
tick's sendDirtyEntityData, so the movement speed without the effect's
modifier reaches the client a tick later and vanilla's client runs fast for
that tick. GrimAC's Simulation flagged the Horizon client on that tick
(0.051 off with Speed II, decaying over the next ticks).
LivingEntity.onEffectAdded/onEffectUpdated/onEffectsRemoved change
attributes on a server only; a server's client now keeps the modifiers
ClientboundUpdateAttributesPacket sends.

A mod jar with no classes, a pack.mcmeta and a data/ folder is a data pack.
For a 26.2 or 26.3 modpack, `port` now upgrades such jars to 26.3 (the
upgrade-datapack code; 26.3 ones are copied) into the profile's
home/new-world-datapacks/ instead of carrying them as content mods, which
dropped their data/minecraft overrides. The game copies that folder into
each new world it creates.
Before its jar is read, a mod whose Modrinth project also ships as a data
pack counts as data tier, so `fetch` gets the jar; the jar then decides.

The Modpacks page now opens with "Found on this computer": the modpack
instances the CurseForge app, Prism Launcher, MultiMC, the Modrinth App,
ATLauncher and the official launcher keep in their usual folders, read with
`other_launchers::scan` on a thread. Each row shows the app, Minecraft
version and loader, and imports the instance with one click through the
same path as "Import an instance folder…" (a Prism instance from its own
folder, so its `mmc-pack.json` still names the version). A pack already
imported opens instead.
Only instances with a `mods` folder of their own are listed: the official
launcher's profiles that play in its own folder are the player's everyday
game, not a pack. The two new strings are in every language table.

StorageDataAccessor.getData returns the stored compound itself, and
DataCommands.manipulateData edits it in place. A wildcard set on a
non-empty byte, int or long array clears the array before it rejects a
string, so the command fails with nothing counted and the storage keeps
the cleared array. Horizon edited a copy and dropped it on the failure.
On that failure, a /data modify on storage now puts the edited compound
back with CommandStorage::set_unsaved: only an id that is stored is
replaced, and the storage is not marked for saving, as vanilla calls no
setData. The error, the result, the success path and the entity and
block copies are unchanged.

Decoration scheduling measured, sorted and ranked every proto chunk each update.
Ranks are unique, so only chunks without one need their distance; the rest

SulfurCube.mobInteract ends with Bucketable.bucketMobPickup, and a sulfur
cube is picked up with an empty bucket (canBePickedUpWithBucket), not a

so a click with a bucket left the cube where it was.
After the cube's own baby, primed, shears and swallow branches, an empty

filled_bucket and player_interacted_with_entity, drops the leash, discards
the cube and gives the bucket through ItemUtils.createFilledResult, as the
other bucketable mobs do. The native bucket hook hears it.
The filled bucket carries SulfurCube.saveToBucketTag: the cube's age and
age_locked in bucket_entity_data, and its body block as

SulfurCube.collectEquipmentChanges runs in LivingEntity.tick
(detectEquipmentUpdates) when the body item changed. It removes the
previous body's archetype modifiers and adds the new body's as transient
modifiers: knockback_resistance, explosion_knockback_resistance and
bounciness (add_value), friction_modifier and air_drag_modifier
(add_multiplied_total). /attribute read the defaults for these five on a
cube with a body.
A sulfur cube now has its own attribute map from its type's defaults.
The five attributes go to that map, and the tick adopts the body's
modifiers there with the existing AttributeInstance operations. A
transient modifier shadows a permanent one with the same id, and the
removal takes both, as in vanilla. The archetype table also gets its
explosion knockback resistance, from the 26.3 data.
The save writes the base and the permanent modifiers of these instances,
not the transient ones. A command change of the knockback base or of a
permanent modifier also goes to the store that the bodiless physics
reads, so that effect stays as before.

LivingEntity.kill is a generic_kill hit that calls LivingEntity.die before

The /kill mob arm now runs the existing death routine (mob_died) at once
for a mob that this kill takes from alive to dead, behind the existing
`died` guard, as a frog's bite already does. The native living_death veto,

🤖 Agent: moves 575 lines of game.rs's inline tests to game/core_tests.rs with unchanged bodies; the horizon-client test count stays 1159, and the tests open PRs touch stay put.
🤖 Agent: pure move of spawn_player (117 lines) to game/player_spawn.rs; test_world_input_capture's loading-completion check reads it from the new file and still sees the player set before the mouse capture.
The previous implementation was translated from OpenJDK's
java/util/HashMap.java (GPL-2.0), which Horizon's MIT licence cannot
carry. This one was written in a two-person clean room: the implementer
worked from a behaviour spec, the Java SE API documentation, CLRS
chapter 13 (red-black trees) and runs on a real JVM, and never read
OpenJDK's source or the old file.
Entries live in a slab of nodes addressed by u32 index. A bucket holds
the first node of its bin's list and, for a tree bin, the root of a
red-black tree over the same nodes, whose links sit in a side table the
map allocates with its first tree bin. The public API is unchanged.
Unit tests pin iteration orders printed by java.util.HashMap on OpenJDK
25: a doubling from 16 to 32 buckets, a tree bin made at 64 buckets
after two doublings below 64, a tree-bin insertion after its tree
parent, movable and cursor removals from a tree bin, copies, and the
cursor's error order.

🤖 Agent: pure move of 190 lines (startUseItem, interactOn, the placement/bucket cancel hooks) to game/item_actions.rs; the Player actions docs rows now point fn use_item and fn attack at their files.
`MeleeAttackGoal.canContinueToUse`'s follow branch returns
`isWithinHome(target.blockPosition()) && !(target is a spectator or
creative player)`. Horizon's `MeleeAttack::can_continue` only refused a
creative player: a mob with a home kept chasing past its radius, and a
player who became a spectator was still chased.
`DrownedTridentAttackGoal` overrides `canUse` with the trident test and
inherits `RangedAttackGoal.canContinueToUse`, which calls `canUse()` again
(and falls back to a target it is still walking towards). Horizon's
`DrownedTridentAttack::can_continue` asked only the base ranged goal, so a
drowned whose trident was gone kept the trident attack running once its
path was finished.

fs_oit_cull writes the nearest opaque see-through depth into the depth
buffer, and the later OIT stages test GreaterEqual against it, so an opaque
fragment is compared with its own depth. On Metal, position.z can differ from
the rasterizer's depth by an ulp, which dropped random pixels of players and
mannequins (horizontal dashes, text behind showing through). Write the depth
4 ulps farther: the fragment still passes, anything visibly behind is culled.
Checked on macOS (Metal, Apple M1) with a mannequin and a text display; not
yet on Linux (Vulkan).

After a close blast a mod can now dull and quieten the world's sounds while
its own ringing plays clearly: native_muffle_sounds(amount, lowpass, ticks,
exempt) turns every sound down by `amount` and low-passes it by `lowpass`
(down to 300 Hz), both fading back over `ticks` client ticks and held while
the game is paused. The sound events in `exempt` play through untouched,
those already playing too.
The mixer mixes the muffled sounds into a bus of their own, runs two
one-pole low-pass stages and the duck over it, and adds it to the exempt
ones. The level glides over 20 ms so tick-sized steps don't click. While no
muffle is set or once it has faded, sounds mix straight into the output as
before. The sound engine marks a channel exempt as it starts, and marks the
playing ones again when the list changes.

/clone from <sourceDimension> ... to <targetDimension> ignored both
arguments: an unknown name cloned in the current level, and a valid
other dimension wrote into the current level instead of its own world.
As CloneCommands does, sourceDimension is resolved as begin is read and
targetDimension as destination is read, each position checked loaded in
its own level; an unknown name fails with argument.dimension.invalid
(the built-in dimensions, as execute in checks them), the source first.
The overlap check applies within one level only. The blocks are read in
the source level and placed in the target level through the existing
level swap (enter_command_level), each entry checked; the coordinates
are resolved in the command's own context first. The command's own
level is put back on every path, before the command reports.

`CatTemptGoal` overrides `canUse` with `!cat.isTame()` but does not
override `canContinueToUse`; `TemptGoal.canContinueToUse` ends with
`return this.canUse()`, so taming a cat mid-tempt ends the goal. Horizon's
`CatTempt::can_continue` ran only the base `Tempt` continue, which never
asked whether the cat was tamed, so a cat tamed while following a fish
kept following it.

The HUD atlas reserved `horizon/modimage` (native_mod_image, API 355) only
when the launcher's native-mods.json listed mods, so a bundle applied with
horizon-mixins by hand or by a mod's own script built a game whose
native_mod_image always returned false.
horizon-mixins leaves .horizon-mixins-stage.json at the root of every
workspace it changes, naming each injection's and module's mod. The build
script turns a record that names mods into HORIZON_MIXIN_MODS, and
built_with_native_mods counts it and installed trait mods as well as
native-mods.json. A release or Nightly has none of them and keeps no slot.

One Cargo feature, on by default, holds the entry points of Horizon's own
extras so a fork can build the game without them
(`--no-default-features --features audio,controllers`) or delete them:
cosmetics, emotes and the "Horizon player" presence (one gate,
game::cosmetics::enabled), the official and partner servers added to
servers.dat, the Options screen's Horizon Settings and Mods buttons, and
the existing discord, friends and heartbeat features it now turns on.
The default build resolves the same features as before and every gate is
cfg!(), so both sides compile in every build. A build without the extras
names the official build on Credits & Attribution. docs/forking.md lists
the extras, their files and their gates.

Zombie and Piglin.setBaby put a transient minecraft:baby speed modifier
on a baby. AttributeInstance refuses to add an id it already holds and
removes a modifier whatever its kind; the next setBaby removes
minecraft:baby again and, for a baby, adds the transient one back. The
transient modifier was computed from the baby state, so /attribute
modifier add stacked a permanent one on it and modifier remove found
nothing to remove.
The add now counts the transient modifier, and the remove takes it away
until the next setBaby (a flag on the mob's attributes, not saved: a
load runs setBaby again). setBaby clears that flag and removes a
permanent minecraft:baby, as vanilla's does.

An absolute /tp zeroes the player's speed, as vanilla's does
(TeleportCommand's relatives carry no DELTA), so the check's teleport
right before the hit left the guest at walking speed and the check

clicks in reach. The slowdown assertion is tightened: the first
post-hit sample must be under 0.75 of the sprint speed and then climb,
which fails with the client's 0.6 cut removed (the old 0.9 bound did not).

- World screens: RealmsResetWorldScreen's tiles, the template list, the

/test only knew the test instances of the game's own data: read_test_def
read options.resources, and the selector ids were the exported built-in
ones, so a test a world's data pack defined was "No matches for
selector". Vanilla 26.3 loads Registries.TEST_INSTANCE from the packs the
world enables when it loads: later packs override earlier ones and the
built-in data, and /reload or /datapack do not change it.
When a world opens (the end of load_world_state), the built-in pack's and
the initially enabled packs' test_instance files are read once, in pack
order, through the existing test instance decoder. They become the
world's test definitions (test_defs) and its minecraft:test_instance ids,
replacing the previous world's. /reload and /datapack leave them as they
are. A game with no world opened reads the game's own data as before.

AttributeMap.pack saves the attribute instances that exist. A fresh
living entity has none (attributes:[]); its first tick creates
movement_speed (LivingEntity.aiStep -> removeFrost -> getAttribute).
The mob writer added movement_speed to every save, so a mob that had
not ticked yet already saved it.
The writer's invented movement_speed entry now waits for the mob's first
tick (its tick count). The instances the load itself makes stay:
Zombie and Piglin setBaby the speed, Rabbit setVariant the attack damage.
Instances the mob was loaded with are kept as before, and the list is

`TradeWithPlayerGoal.canUse` refuses a trader that `wasHurtRecently` or
whose trading player is more than four blocks away, but Horizon's
`TradeWithPlayer::can_use` checked neither. A wandering trader that took a
hit, or whose customer walked off, stayed in the stand-still trade goal
where vanilla ends the trade.
`HappyGhast.HappyGhastFloatGoal` overrides `canUse` with
`!isOnStillTimeout() && super.canUse()`. `FloatGoal` does not override
`canContinueToUse`, so `Goal.canContinueToUse` asks that same overridden
`canUse` on every tick: a player standing on the ghast makes it stop
floating. Horizon's `HappyGhastFloat::can_continue` re-ran only
`Float.can_use`, so the goal kept hopping in water under a player who was
holding it still.
#7820 gave the entity pipeline a constant depth bias of 128 so entities win the tie with
coplanar terrain. HDR output marks what it draws by drawing the same quads again, alpha only,
GreaterEqual against the depth it left, but without the bias: every mark tested a hair behind
that depth and failed. Mobs lost their HDR lighting, light sources in the hand stopped shining,
and the empty hand only looked right by reading the ground's mark behind it.
The marks after entities, the hand (unmark and mark) and translucent particles now draw at the
same bias. Translucent items, additive draws and the OIT stage follow unbiased pipelines and
keep the unbiased mark.

On the float HDR frame the last pass guessed which pixels still showed the world
(`shows_world`) and clipped everything else at white, so the world's light dropped to
SDR under the chat's see-through background, a menu's backdrop and the coloured camera
overlays. Where the device records HUD coverage (#11896) the frame is now drawn in
layers, as the HDR note's step 3 specifies:
- After the world and the hand, `Hdr::resolve` turns the frame's marks into light once.
The camera overlays, post effects and entity outlines draw on light after it.
- `keep_world` becomes a pass: the world clipped to white, alpha 0, into a HUD target in
the frame's format, which the HUD and menus draw on with their unchanged blends.
- The last pass lays the HUD over the world's light by its coverage, in gamma as the HUD
blends (H = P - (1 - c) B, then H ui^(1/2.2) + (1 - c) W). UI Brightness scales the
HUD's own part.
- The menu blur blurs that composite, light included, and makes it the world the menu
draws over.
Until the tone curve, a screenshot is the HUD target and the world icon the world, both
clipped at white; the -hdr.png is the full picture. The legacy path, the 16-bit frame and
HDR off are unchanged.

An Allay loaded with a finite minecraft:liked_player memory kept it

memory down.
- The memory's time to live is kept next to the existing liked-player
state (None for a memory that never expires), read on load and
written on save as MemorySlot.visit does.
- The Allay's AI step, which NoAI skips like customServerAiStep, ticks
it as MemorySlot.tick does: it counts down, and is cleared on the
tick after it reaches 0.
- Giving an item sets the memory without a time to live
(Brain.setMemory), taking it back erases it, and the /data path that
keeps the memory keeps its time to live too.

from OpenJDK's FdLibm.java (GPLv2 with the Classpath Exception),
aarch64::{sin, cos} from HotSpot's AArch64 trig intrinsics (GPLv2), and
round_f32 from OpenJDK's Math.round(float). Horizon is MIT.
Rewritten in a two-person clean room from Sun's fdlibm 5.3 C sources, a
behaviour-only description of the AArch64 sin/cos, and the Java SE API
documentation:
- jmath/fdlibm.rs (new, Sun's notice at the top): log, log10, cbrt and
hypot ported from e_log.c, e_log10.c, s_cbrt.c and e_hypot.c; sin_fma
and cos_fma, fdlibm's sin and cos (s_sin.c, s_cos.c, k_sin.c, k_cos.c,
e_rem_pio2.c) with fused multiply-adds, as Math.sin/cos on AArch64.
- jmath.rs: round_f32 from the Java SE specification of
Math.round(float); the module doc says what each platform computes;
jmath::fdlibm and jmath::aarch64::{sin, cos} keep their paths.
- geometry/trig.rs: Sun's notice above its fdlibm asin/atan/atan2 ports.

Absorption adds 4 per level to max_absorption (an ADD_VALUE modifier),
and LivingEntity clamps the absorption amount to getMaxAbsorption: when
the effect starts (setAbsorptionAmount) and when it goes
(onAttributeUpdated). A mob's max_absorption lived only in the command's
per-target attribute map, without the effect's modifier; /effect clear
left the amount, and expiry subtracted 4 per level, so a mob with a
raised base lost absorption it keeps in vanilla.
The mob's max_absorption now uses the attribute map it already has for
armor; its effective value counts the effect in the ADD_VALUE phase. The
add clamps the amount to it, /effect clear and expiry clamp to what is
left. The command-set base and modifiers stay unsaved, as before.

THIRD_PARTY_NOTICES.md gets a "Code removed for its license" section for
anyone holding an older version: the shader pack code written from Iris's
source (LGPL-3.0, removed in #1561) and the math functions translated from
OpenJDK and HotSpot (GPL-2.0, #6741). In those versions that code is not
covered by Horizon's MIT license.
CONTRIBUTING.md says OpenJDK's own source is GPL too, so it is off limits
like any GPL project; Java's behaviour comes from its documentation, a JVM's
results, or a permissive original such as Sun's fdlibm.
docs/how-horizon-is-built.md no longer says Horizon holds no Minecraft data
and never downloads it: the datafix tables come from vanilla's code, and the
launcher downloads 26.3 from Mojang for a signed-in account that owns it.

In a frozen level, water a command placed in newly forceloaded chunks
before the next world tick never flowed: the chunks' tick containers
were only registered by tick_blocks (a running world tick) or by
postprocessing, so the water's flow tick found no container and was
dropped. Vanilla registers them when the chunk becomes a full chunk
(LevelChunk.registerTickContainerInLevel), before any command sees it.
update_world now runs the existing sync_tick_chunks once the streamed
chunks are resident and the unloaded ones are saved with their ticks,
so registration comes before the tick's commands and world tick. Only
an authoritative game (not a server's client) registers.

A block entity's faces were baked with `minecraft_mix_light` and their
normal left zero. A shader pack's `gbuffers_block` (or its fallback)
receives the unshaded colour and the face normal from Iris, then applies
its own lighting, so Horizon's baked shade was applied a second time:
chests, shulkers, banners and the rest came out darker than the terrain
around them (#8390).
`draw_part` now emits the tint alone and the face's world normal
(`normal.w` = 127), and the entity shader applies `minecraft_mix_light`
from it, as it already does for mobs. Lights that are not the level's (an
item preview's `Lighting.Entry`, which the entity shader cannot know)
stay baked into the colour with `normal.w` 0, which is the path
`game/item_draw` gives block-entity items in inventories and hands.
The parity harness compares the tint and the face normal; the loom's GUI
preview keeps its baked `ITEMS_FLAT` colour. The chest cache test now
checks the nether flag reaches the shader instead of changing a baked
colour, so the cached geometry serves both dimensions.

A pack that adds font providers over the game's own can leave the overlay without the vanilla font sheets its merged font/default.json names. Every glyph then became the missing box. Read a bitmap sheet, TrueType file or Unihex file the overlay lacks from the game's own root, as vanilla's resource stack keeps the game below every pack. Font definitions stay the overlay's, so a pack filter can still hide one.

ClientPacketListener.handleMoveEntity decodes a move's delta from the
entity's position codec base, which AddEntity, a move and a position sync
set and a TeleportEntity leaves alone. Horizon counted it from the
tracked position, which the teleport had moved: when a command teleported
a vehicle, its rider was told the teleport and then the tracker's delta,
and saw the vehicle (and themselves) as far again past where it was.
lan_e2e gains `vehicle-teleport`: a strider the guest rides, teleported
3 blocks, is where the server has it in the guest's game.

Ludovic (2026-11-07): "In the launcher you just don't see the items." The Shop
now opens on the season pack across the top (its looks drawn side by side, name,
item count, price, Buy), then rows of big tiles: Looks, each collection's items,
the founder set and the Supporter badge. A tile is the item drawn, its name and its
price; it lifts under the pointer. A tile opens it big on the account's own player

- Pictures: the Wardrobe's CPU renderer, framed on the item (preview::fitted_view),

- Buy and Gift are one checkout of that offer through the same web checkout;
prices still come from the catalogue and the service's set rules.

A bitmap provider's file may be any texture, and HUD packs keep sheets outside textures/font. HudAtlas already received the sheet from the font commit, but only if the texture was packed: WALKED_TEXTURE_FOLDERS did not include custom paths such as textures/lumiere/hud, so those sheets still fell back to per-glyph run-time copies. Collect every bitmap provider's file while building the atlas, deduplicated against the walked textures, so its glyphs use the sheet's atlas rect.

A bitmap provider may name any texture, and server HUD packs keep their glyph sheets under their own namespace or a path such as textures/lumiere/hud. The HUD atlas already holds those textures, but Font only looked up sheets under font/, so every glyph was decoded from disk and copied into the 512-row run-time region one by one. When that region filled, a glyph became the 6-pixel missing glyph, shifting the rest of the HUD line.
Look the sheet up by its atlas name for every namespace and keep every atlas sprite available to the font. Glyphs now use the sheet's atlas rect, so their advances come from the original texels and the run-time region is not involved.

With HORIZON_HDR_FRAME=float, HDR on and no shader pack, on devices with independent blending, each
HUD and menu pipeline gets a variant with a second output into an R8 target: how much of the world
behind it the draw hides (docs/design/hdr-linear-light.md, The HUD and menus). The fragment shader
is wrapped as it is, so the primary colour, its blend and alpha are unchanged, and the coverage
follows the draw's final colour and blend: layering by its alpha, additive draws not at all,
darkening ones by how much they darken, inverting and replacing ones fully. HORIZON_HDR_DEBUG=coverage
tints it magenta in the last pass; nothing else reads it yet. A resource pack text shader without a
colour output is dropped as an unusable one is, instead of panicking.

The GL backend reported MAX_TEXTURE_SLOTS (16, WebGL2's minimum) as max_sampled_textures_per_shader_stage even on desktop GL, where drivers usually offer 32.

A layout or pipeline the backend cannot take (a stage's bindings past its sampled-texture limit, say) reaches the device's error scope. A native pack built its frame, stages and passes outside one, so wgpu's validation error hit the default handler and crashed the game (#10095). Build the pack in a scope and return the first error, which the shader pack screen already shows as a refusal.
The test asks for OpenGL's minimum 16 sampled textures per stage and builds a sky-only pack whose layout needs 19: the pack is an error, not a validation panic.

A client mod asks once a frame (`hold.hold()`, or `hold.hold_within(x, z, radius)` for circles):
sections already on screen that are meshed again are uploaded as ever but wait beside the meshes
drawn, and letting go swaps them all in on one frame with nothing left to upload. Smaller circles
let go of what they leave. In single player, far terrain waits too for the columns the server
changes beyond the view inside the hold, and takes them in when it lets go of them. Bounded: 30 s,
1 GiB of waiting meshes, the arena running out; ended so, it stays off until no mod asks for a
frame. Clearing the sections (another world or dimension) and unloading columns drop what waits;
arena compaction moves waiting meshes too. Renderer::upload keeps its order on the normal path
(before_mesh / upload_mesh / after_mesh). Tests in gfx/hold.rs; docs in native-mods.md; fragment

Without XDG_RUNTIME_DIR (containers, some WSL and minimal setups) the
control socket was /tmp/horizon-control.sock, a fixed name in a folder
every user shares. Another user who bound it first made --control fail
to start, and horizon-ctl then talked to their socket.
When the temporary directory is shared (world-writable, as /tmp), the
default endpoint is now horizon-<uid>/horizon-control.sock in it. The
game makes that folder 0700, and both the game and horizon-ctl refuse
it unless it is a real folder, owned by this user, that no one else may
enter. A temporary directory of the user's own (macOS's $TMPDIR) is
used as before, so nothing moves there. The launcher's copy of the
default endpoint (game_tools.rs) follows the same rule.

A mob loaded or summoned with FallFlying:1b kept the flag even when it
could not glide, and a gliding mob's elytra never wore. The flag was
only the raw tag's value: the loader did not read it, the save only
supplied a default, and the mob tick had no updateFallFlying step.
- mob_from_nbt reads FallFlying into the mob, and mob_to_nbt writes the
mob's current flag (LivingEntity.read/addAdditionalSaveData).
- The mob's aiStep, with or without AI, runs updateFallFlying while the
flag is set: canGlide (ground, vehicle, levitation, a glider whose
next damage does not break it) clears the flag; every 20 glide ticks
Util.getRandom picks a glider from the mob's own random.
- The game applies that wear with the existing durability path
(Unbreaking from the level's random) to the mob's kept stack.
- LivingEntity.tick counts fallFlyTicks after aiStep.
Glide travel, checkFallDistanceAccumulation and the ELYTRA_GLIDE game
event are not part of this change.

Closes#11814.

view_distance and chunk_center come straight from Login,
SetChunkCacheRadius and SetChunkCacheCenter, any i32 a server sends.
remote_chunk_in_range added 3 to the radius and subtracted the centre,
and the streaming radius and sent_radius added 1: a server sending
i32::MAX or i32::MIN panicked a debug build, and in release (no
overflow checks) the wrapped range dropped every loaded chunk.
The storage range is now in_storage_range: the same ClientChunkCache
rule (radius at least 2, plus 3), with a saturating add and abs_diff,
so nothing changes for any radius a real server sends. The +1s
saturate too.

Each distinct pack selection gets its own overlay folder under
.horizon-cache/resourcepacks, holding a full unpacked copy of its zip
packs, and nothing removed old ones. Every server pack, and every new
version of one, left a permanent copy the player can't see: ten
servers with 100 MiB packs kept about a gigabyte.
resource_root now marks the overlay it returns as used by this process
(a shared lock on <overlay>.overlay-cache.use, held until the process
exits, whose time is the last use), then keeps the 8 most recently used
overlays in the folder and deletes the rest. An overlay another
process uses or is building is skipped, so two games sharing a game
folder never pull one out from under each other; the marker goes before
the folder, so a half-deleted overlay is never reused. The lock files
stay, as build() already requires.

After the encrypted join, the guest offered the session on a random
127.0.0.1 port for 30 s and handed it to the first loopback connection.
Any other local user or process that found the port first got the
authenticated session to the host's server, and a web page aiming
fetch at local ports could send HTTP into the tunnel and make the
player's own join fail.
serve_loopback now returns a Loopback with the port, a random 16-byte
token and the thread. A connection must send the token within a second
of connecting (compared in constant time); anything else is dropped and
the port keeps waiting until its deadline. The client's join_friend
passes the token on, and run() writes it raw before the handshake.

In PCP and NAT-PMP a lifetime of 0 means the mapping is deleted, but a
success reply carrying 0 was taken as a mapping. Mapping::due() was
then always true, so the host renewed on every 100 ms wake-up of its
loop (a UDP exchange each time, under the reach mutex) while
advertising a direct address that no longer existed.
pcp_map and natpmp_map now refuse a zero lifetime when they asked for
one (a delete, which asks for zero, still expects zero), and due()
never fires sooner than 30 s after the last renewal, so a router that
grants a few seconds isn't asked again ten times a second either.

Applying packs builds an on-disk overlay: every file under assets/ in
every zip pack was inflated (up to 1 GiB each, whole in memory) and
written out, on every worker thread at once. A gigabyte of zeros
deflates to about a megabyte, so a server pack at the 250 MiB download
limit could write some 240 GiB to the player's disk and hold a 1 GiB
buffer per thread, once the player accepted the pack prompt. Vanilla
never unpacks a pack.
Zip::copy_to now streams an entry to its file 64 KiB at a time, taking
each piece from a byte budget shared by the whole build: 16 times the
zips' size on disk, at least 64 MiB, at most 8 GiB. Past it the build
fails with FileTooLarge (so the reload drops the server packs, as for
any failed build) and the half-written overlay folder is removed. An
unreadable entry still costs only that file. Memory per thread is now
the compressed entry plus one piece.

🤖 Agent: Realms subscription URL (subscriptions/$WORLD_ID), JSON-bool settings, InviteCodeList array/result parsing and the JSON Content-Type now match the 26.3 RealmsClient; same Microsoft session, no other auth (Mojang rules OK); footer buttons wired to the selected code. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
Chunk sections already put their solid quads in the arena as one 24-byte
record each instead of four 24-byte vertices (`mesher::packed`). Far tiles
never could: that record's coordinates are a block grid of 16, and a far
tile's quads are merged rectangles of a voxel column's exposed side,
hundreds of blocks wide. So they stayed at four vertices a quad, and at
`lodDistance` 256 they were by far the largest thing the renderer held.
A far quad is much more regular than a chunk's, though -- a rectangle in an
axis-aligned plane, one colour, one light and one layer across all four
corners, with UVs `lod::mesh::emit_quad` derives from the positions -- so a
record of its own holds it in the same 24 bytes, and terrain.wgsl's
`far_corner` does what that function did. The two layouts share the arena
and the pipeline; a draw's base vertex says which it is (`FAR_BASE`).
Measured on a settled LodTest at `lodDistance` 256, render distance 16, the
same binary with `HORIZON_FAR_PACK=0` and without, each run settled on the
same 4424 tiles and the same quad count to within four:
far vertices arena pages GPU allocated
four vertices 492.5 MiB 960.0 1241.7 MiB
a record a quad 127.4 MiB 640.0 921.8 MiB
365 MiB less vertex data, and 320 MiB less video memory actually allocated
rather than merely accounted for. 24.8 bytes a quad: a record each, and the
few quads that spill. Both figures repeated exactly over two pairs of runs.
Frame time is unchanged. Over the same flight, the mean of two pairs:
avg FPS 1% low GPU avg
four vertices 171.0 95.8 5.390 ms
a record a quad 170.3 94.9 5.420 ms
The pairs disagree on the sign -- the compact layout was 1.5% slower in one
and 0.7% faster in the other -- so the difference is run variance, not the
cost of expanding a record. Worth stating because one pair alone read as a
regression.
Nothing here reasons about which record is right for a quad: `pack` builds
one, rebuilds the four vertices from it, and keeps it only if they come back
bit for bit. A quad no record reproduces is kept as its four vertices, as
`mesher::packed` keeps one; in practice that is the fluid faces, whose
surface sits at 8/9 of a block, and about 1% of quads.
`lod::mesh`'s `every_quad_the_mesher_emits_packs_and_comes_back` holds the
layout and the mesher to each other over real terrain, which the layout's
own tests cannot: they check its records against its own copy of what
`emit_quad` does, and would pass just as well if the two had drifted.
A same-build control says the picture does not change: two launches of the
identical build differ in 50.7% of pixels (16.0% above the animation noise
floor, worst channel delta 76), because far-tile refinement does not settle
identically between launches. Packed against unpacked differs in 40.5%
(12.8% above the floor, worst 77) -- less than the control.

Two camels in love in a built world: the breed goal starts, then one loses a
point of health and is refused, and a rider also refuses it. Without the
canParent guard the wounded camel still starts the goal.
`Camel.canMate` is `partner instanceof Camel && this.canParent() &&
camel.canParent()`, and `AbstractHorse.canParent` requires no vehicle or
passenger and full health (a camel's `isTamed` is always true). The shared
`Breed` goal applied those checks only to horses, donkeys and llamas, so a
camel stayed free to breed while hurt or carried.
Camels still pair only with camels: the `camel` flag feeds the canParent
guard only, not the partner species rule.
KineticWeapon.damageEntities and PiercingWeapon.attack hit every entity
along the view, players included (PiercingWeapon.canHitEntity:
canHarmPlayer, not the same vehicle). Horizon's stab targets were the
mobs only. A guest's spear now also reaches the other players of its
level; each stab is worked out as the attacker in their turn and lands
through the PvP path once the hub is back, with the spear's damage type,
the 0.4 push and the weapon's Knockback, the dismount, thorns and the
kill score, then the attacker's wear, stats, exhaustion and hit feedback.
The kill score and thorns of pvp_land move into pvp_aftermath, shared by
both. lan_e2e gains a `spear` check: a jab and a sprinting charge hurt
the host, and with the pvp game rule off neither does.

The test builds a world with a stone ceiling cell inside the standing box
but above the sitting box, then asks RandomSitting, the arm the goal
selector calls: 200 asks must all be refused. A second camel with open sky
fires within the same 200, so the refusal is the pose check and not the
state setup. Dropping the can_change_pose conjunct fails the first loop.
`CamelAi.RandomSitting.checkExtraStartConditions` ends with
`body.canCamelChangePose()`, which is
`wouldNotSuffocateAtTargetPose(isCamelSitting() ? STANDING : SITTING)`.
RandomSitting did not ask, so a camel sitting under a ceiling that blocks
its 2.375 tall standing box (its sitting pose is 0.945 tall) stood up into
it. The `can_change_pose` helper already existed for the elastic leash pull.

Drives the real goal selector on a built test world: hurt the frog with a
PANIC_CAUSES damage, tick the goals once, and assert the panic goal started
and left vanilla's 2.0 in `Navigation.speed_modifier`, the value
`SmoothSwimmingMoveControl` multiplies. Reverting the constant fails it with
1.25 against 2.0.
`FrogAi.initCoreActivity` builds the brain's core activity with
`AnimalPanic(2.0F)`, but the goal list used 1.25.
`PanicGoal.start` hands the multiplier to `PathNavigation.moveTo`, and
`SmoothSwimmingMoveControl.tick` computes
`speedModifier * getAttributeValue(MOVEMENT_SPEED)` and then multiplies by
0.1 on land or 0.02 in water. A frog's movement speed is 1.0, so a fleeing
frog should move 0.2 blocks a tick on land and 0.04 in water; at 1.25 it
moved 0.125 and 0.025, 60% slower.
26.3 ends sign_update with the side as a VarInt; 26.2 and older read it as a

Loading a generated area spends 16% of Persistent::load (the worker's
chunk load) in PalettedContainer::from_packed, and nearly all of it is
check_indices: a scalar bounds check of every entry of every section
(~10.6 instructions per entry, 22M entries per 529-column area).
check_indices now rejects a whole word at once. Adding 2^bits - palette
to a word lifts every field by that much, so a field carries out of its
own bits exactly when its index is past the palette; the carry out of
each bit is computed for the whole word with (a & b) | ((a | b) & !sum).
A field can only appear bad where a genuinely bad field precedes it in
the same word (a carry adds one to it), which never turns an accepted
input into a rejected one, and the offending word is rescanned entry by
entry on the error path so the reported index is the same first
offending entry as before. The last word's padding fields are biased by
zero, so they cannot look bad, as the entry-by-entry scan ignored them.
The same set of inputs is accepted: the early return when the palette
holds exactly 2^bits entries was already there and stays.

A version's first start read its thousands of small files one by one, about
100 s under Windows Defender here, because only the game wrote

to 8 threads (43 s against 281 s on one, on a fresh copy); the start then
loads in 1.2 s. The game stays the fallback, on its one idle thread.

🤖 Agent: Requeued at the author's main merge 552f2c1b4: same net patch as d8676fff0 (identical patch-id), whose parity failed only command_exec's 26 /say lines that #11687 has since fixed on main. The change: shader packs in the End draw the sky fan under the dragon fight's fog like the rest of the pack's sky.
🤖 Agent: a refused START_FALL_FLYING now flips the glide bit of sent_shared so a flags update goes out, as LivingEntity.stopFallFlying's set(true)+set(false) dirties the flag in vanilla (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: the Patch notes tab's three orphan strings are gone from the 86 lang files, so the launcher's i18n tests pass (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: /damage ids now come from the world's damage catalog and are replaced on each world open, so a pack's type doesn't leak into the next world (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: the single-player memory connection sends every ready view column in one batch before PlayerLoaded (about 0.5 s saved at render distance 12), then the 64-per-tick cap comes back; socket guests keep vanilla pacing. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: new client-only, read-only native hook chat_suggestion_applied fires after Tab or a click applies a suggestion, with the replaced range in UTF-16 units of the list's original input; fragment stamps cleanly on main. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: port-pack events answers VillagerTradesEvent/WandererTradesEvent with the trade_set and villager_trade registries 26.x moved trades to. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: Studio playback of .mcpr recordings through the normal client handlers (B1 slice of #9712, +2120), only active when a recording is opened; F1 now hides chat and tab list as vanilla Hud.extractRenderState does. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: new horizon-polytone crate reads Polytone targets and biome/dimension attribute layers from the public wiki only (Polytone is GPL, its source not read); no caller yet, first step of #11486. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: the hook runs after the vanilla shuffle so RNG draws are unchanged and a no-mod dispatch is an empty loop; fragment wind_burst passes tests.test_stamp_native_hooks and --check --only on main merged in (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: Studio rows and buttons now register as focus targets and the wheel moves one whole 40 px row per notch, which also stops part-scrolled rows drawing over the title and makes the last recording reachable. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: only block/ and item/ paths equal to the old id are renamed, so a mod's own pulley:block/chain and chain_command_block_* stay, and files are rewritten only when something changed (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: recipe suggestions reuse json_ids_of_every_namespace like /loot, and the dead ids_under goes (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: The unsupported placed features are now named in the log (capped at 20), which is what a pack author needs to fix them. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: under TAA the flame gate now uses a frustum widened by one rendered pixel per side (jitter is at most half a pixel: 2× margin), one extra frustum per frame, shader packs still bypass. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: with entity culling off the decision is Bypass before any bounds are read, so the posed-envelope walk over every model point of every copy is now skipped (TAA condition dropped), RNG order of cluster_poses pinned by a test. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
🤖 Agent: TCP keepalive (10 s + 3×3 s) now ends dead friends tunnels and relay bridges in ~19 s instead of holding them until the 120 s idle; the stack buffers replace one Vec per connection, not per read. (union of 74 heads on main: fmt, clippy -D warnings, tests green).
Evaluate the supported damage-only subpredicate against modeled damage and
existing effective component presence. Preserve removal precedence and leave
unsupported conjunctions on their existing path.

GitHub's runner moved its binaries to bin.<version>/ after a self-update, so
`pgrep -f "$runner/bin/Runner.Worker"` never matched: runner-gc took busy
runners for idle and deleted the probe builds and old prepared resources of
two running parity jobs (2026-11-07). Match bin*/ in runner-gc,
checks-runners.sh and linux-runner.sh.
runner-gc also counts shared-local/parity-target (19-24 GB per runner),
recreates it empty after removing it (a dangling .local link failed every
harness), and drops harness folders over 2 GB untouched for 6 hours.

The arena's /kill @e[type=!player] kills the previous case's cow, and the
cow drops beef and leather as it dies, after the selector was evaluated.
Those items fall onto the next arena and can hit the floor while the next
case measures, at a wall-clock moment: parity-main 42359055402 read power
2 before item-stone on vanilla's side, and playhorizon read 2 after
item-carpet in 1 of 3 runs at 67902962fd. Both cases follow a cow case.
A second /kill @e[type=item] removes the drops; setup lines aren't compared.

🤖 Agent: fixes main's red clippy since #11561 (1.95 lints on interpolation.rs: is_multiple_of on non-zero unsigned divisors, as_chunks_mut::<4> quads); workspace clippy clean on main + this.
Thorns on the player answered a mob's hit with generic damage that had no
attacker, so the mob was not knocked back, did not turn on the player and
dropped no experience when it died of it. It now hurts the mob by
`minecraft:thorns` damage the player caused (`DamageEntity` with the
wearer as owner), rolled from the mob's own random, and the held weapon's
Breach applies as on any hit by the player.
The whole equipment counts, in `EquipmentSlot` order: the main hand, the
off hand, then feet up to head (Thorns' slots are `any`), so a Thorns
piece held in a hand answers too. Each piece rolls its chance, hurts the
attacker and wears in that order, also when the attacker is already dead.
A piece that takes no wear, or a creative player's, is left alone.
A mob hit by thorns damage plays `enchant.thorns.hit` where it stands
when the hit lands whole, silent or not (`playSecondaryHurtSound`).
Part of #9954.

Both PRs added a signed AbstractHorse temper: #11483 for the seven horse and llama species, this one for camels. Keep one field, equine_temper, for every equine: the loader reads Temper unclamped for all of them, temper()/modify_temper() use it for camels too, and the camel saver writes it.

#11631 adds saved_piece_id (PiecesContainer.load's RENAMES) to the same file; read_jigsaw_start now asks it instead of its own copy of the four old ids. The upper-case id case is dropped from the test: Identifier.parse refuses upper case, so vanilla never reads 'MINECRAFT:JIGSAW' as a jigsaw piece. Land #11631 first.

Add a direct parity suite for the landing branch of
FallingBlockEntity.tick: real falling entities into air, solid blocks,
water, plants, slabs, cobwebs and moving pistons, with concrete powder's
water contact and the anvil landing event behind --no-contact.
🤖 Agent: attributes only, no code removed; the 30 kept allow(dead_code) now carry a reason (19 native mod API). Windows/macOS-only code is the risk, CI's other platforms cover it.
Extras moves onto settings_shell, which draws with graphics_style, so the

🤖 Agent: socket2 0.6 keeps every call direct.rs makes (set_reuse_address, the unix-only set_reuse_port, set_only_v6, connect_timeout), so the friends socket code needs no change; lock loses 11 packages.
🤖 Agent: one workspace rust-version (1.95, which horizon-mods already needed); the second commit is clippy's let-chain/as_chunks/is_multiple_of rewrites, all on unsigned values with non-zero divisors, so no behaviour moves.
ordered_tick: main's obstacle grid for the orb move kept after the
merge scan and the followed-player pick. A kept followingPlayer now
stays at exactly 8 blocks: ExperienceOrb.followNearbyPlayer re-picks
only past distanceToSqr > 64. Orb merge fixture keeps merge_new_orb.

🤖 Agent: near sections no longer dither over far terrain (fade() is 0 or lod::HELD), and the replaced tile still stays behind for lod::FADE through previous, so no hole opens; the test bound lowered to 1,000 matches the half that now come in whole.
🤖 Agent: respawn_world_point and disconnect_crafting reuse generate/world only after a generate/finished marker, written after server.stop(); an old half-made world regenerates once.
🤖 Agent: LocatorBarClient.arc now flags a catch-up tick only before the jab (tick < stabTick); a catch-up right before it still changes the jab's motion, which the harness compares with vanilla, so lunge_motion keeps its signal.
🤖 Agent: drops the harness/probe/field counts from AGENTS.md and CONTRIBUTING.md; the commands and paths around them are unchanged, so nothing a reader runs moves.
🤖 Agent: horizon-ctl screenshot-sequence takes repeatable frames: each waits for the GPU (30 s at most) and for the pack's centre-depth copy, and F2 is refused while a sequence runs. Lands after #11238.
by_registry outlives a world, so a pack's type stayed accepted by /damage in

With [transfer] on and players on, a stop (/stop, a stop signal, the
supervisor's stop or restart) now waits stop_wait_seconds (10 by default,
0 to 60, 0 stops at once as before) so a proxy told server/stopping can
move the players out first. The log says "Stopping in 10 s: a proxy may
move the players out first", which horizon-server takes as the start of
the stop. Every login is refused as server_shutdown, and the server ticks
on and answers the proxy's requests.
The wait ends as soon as no player is placed, at its time when no
hand-over is frozen, and at the latest a freeze's longest time later, so a
hand-over started in time finishes; the whole wait is cut at 90 s, within
the supervisor's 120 s for a stop, so stop_wait_seconds and
max_freeze_seconds may add up to 90 at most when the stop waits. No freeze
starts that this limit would cut: a player its source saved after the
target placed it would be on both servers. A freeze lasts ticks, so its
length is reckoned at the tick length of the moment (the rate's, or longer
on a server slower than its rate). A second stop ends the wait. Then the
stop goes on as vanilla's.

🤖 Agent: raid wave positions (new and cached) now need an entity-ticking chunk in entity ticking range (ServerLevel.isPositionEntityTicking), not just a loaded one; raid, raid_village and raider_celebration harnesses passed.
🤖 Agent: the player save now writes and reads the recursive hidden_effect chain (Poison I under Poison II resumes after a reload); SavedEffect became a struct, guest data uses the same path; active_effects, effect_sync, player_effect_amplifier and status_effect harnesses passed.
🤖 Agent: HORIZON_STILL now settles a frozen world's rain, thunder and rain fog at the level instead of easing them; it only runs with that dev variable set.
🤖 Agent: The shader pack reset (both kinds) lands the in-flight frame before replacing targets, so the next frame draws as a fresh pack's first; dev tooling, no change without the reset command. #11239 follows it.
🤖 Agent: Shader pack shadow settings are now read from the stage that declares them (fragment const settings), with main's noiseTextureResolution kept on the formats stage; only shaders/ packs see a change.
🤖 Agent: Native mods can draw a still-fluid volume in a block; the fluid shading follows Ponder's FluidRenderHelper (MIT, credited in THIRD_PARTY_NOTICES) and nothing changes without a mod calling it.
🤖 Agent: /raid check now finds a raid still counting down (getRaidAt has no started filter), and /raid sound plays the horn only for "local" at volume 2 with the level random's seed; raid and raid_village harnesses passed.
#10523's settings gear now takes its width from the Recipes search box of

The commands' minecraft:damage_type ids came from the vanilla export

build_registries now adds the damage catalog's types to the registry's
ids after the export is applied, keeping the export's tags.

🤖 Agent: The viewer's transfer is a separate server-side path: it only moves ingredients the player already has, leaves grid and inventory untouched when one is missing or the inventory is full, and never teaches the recipe; the vanilla recipe book keeps its own path. Second of the Recipes series, after #10523.
🤖 Agent: The focused text field is exposed to native mods before the character is inserted, so a hook can veto it; the hook fragments stamp cleanly on main. Main merged in (its ChatScreen is_draft argument added to the test).
Vanilla LivingEntity.onEquipItem posts GameEvent.EQUIP (or UNEQUIP) at
the mob and plays the equip sound at volume 1.0. Horizon only did that
for dispensers, copper golems and the player's armor, so saddling a pig
did not activate a sculk sensor and pig/strider/horse saddles played at
0.5.
Interact, inventory, pickup and /item paths now post the event from the
mob, and saddle/harness/armor sounds play at 1.0.

A memory connection that has not reported the view loaded now sends
every ready view column in one batch, and the recorded quota is raised
to cover that send so the following tick is capped again. A socket

🤖 Agent: Transient block entity fields from the update tag reach the native API without being saved; only mods that ask for them see anything new. Main merged in (its new Joined field added to the test).
🤖 Agent: only the automatic count changes, and only where hw.perflevel0.physicalcpu answers (Apple silicon): M4 Pro 13 → 9 workers with no loading or pacing regression over 3 alternating rounds; off Apple the count is unchanged (tested on Linux), and a manual Worker threads setting still wins.
🤖 Agent: #10015's early return dropped /say from chat_capture, so command_exec lost 26 announcement lines; the broadcast now skips only the acting guest (lan_acting), whose copy stays in the capture in order. Console and command-block paths are unchanged. command_exec PASS fresh on the desktop; the control on main 004a39be0 FAILs 16320/16346.
🤖 Agent: a head-on stop on a straight rail no longer blows a TNT cart up (Entity.move zeroes the blocked axis and OldMinecartBehavior never re-applies it), and a glancing hit off its rails now does; tnt_saved_power, tnt_data_adoption and both vehicle harnesses passed.
🤖 Agent: The player-expect move now refuses a full server like a normal join would, and operators still bypass it as vanilla's PlayerList.canBypassPlayerLimit does.
🤖 Agent: 26.2 packet layouts are only used inside a session that negotiated V26_2, and accept_older_clients stays off by default, so a 26.3 client's path is unchanged; the lan_bot tests cover both.
🤖 Agent: The Recipes settings button opens from the inventory browser; the JEI-derived icon is MIT and credited in THIRD_PARTY_NOTICES. First of the Recipes series (#11442 → #11453 follow).
🤖 Agent: only reinforcement_room uses the oracle's light op, so the wait (ThreadedLevelLightEngine.waitForPendingTasks, ticking like settle in a frozen world) changes no other harness's records; command_reinforcements --fresh --repeat 3 PASS 3/3 at desktop load 40-48, where main failed 7 of 10.
Main's thorns check counts events from before the hurt; the PR's helmet

🤖 Agent: dropping the --reference-only assertion makes a plain run go through runner.main()'s full Java/native comparison, and then the strict tags/pot report, so CI now compares instead of exiting in 0 s. mob_discard's default --resources is lab.RESOURCES (the prepared 26.3 folder) and it gets the missing import os. The two sound harnesses take main's #11555 version.
🤖 Agent: data get on a leashed boat now reads its leash from the same save path the world writes (write_boat_leash); merged main twice, boat_leash_view harness passes and the u/3 union builds with clippy -D warnings.
🤖 Agent: breeding now adds one fresh orb of the whole 1-7 roll (no award split, no merge), and XP bottle orbs start 0.25 along the hit face's normal with their motion turned away from it; orb_lava/orb_water/orb_saved_uuid/bed_explosion harnesses passed.
🤖 Agent: OptiFine custom skies draw their layers over the vanilla sky, only when a pack ships optifine/sky and the Horizon sky option is on (a frame without one only clears an empty list); merged main, clippy and the sky tests pass.
The portal parity suite only sent entities through portals: the PortalShape
search that turns an obsidian frame into portal blocks was never exercised.

The automatic pool size was every core but one. On Apple silicon the

🤖 Agent: advancements= in a selector reads the selected player's own progress, a guest's included (EntitySelectorOptions on the ServerPlayer); guest_advancement_selector passes on the merge, now runnable by parity.py.
The two reset-world commits rebuilt on the backups branch (both PRs extend the
same configure screen): the scroll wheel covers the product page, template and
upload lists, and the worlds tab has Options and Backup side by side with
Reset below.

#10015 broadcast /say from cmd_say to every guest and dropped the line
from chat_capture. The acting guest still saw it, but the command
harness reads the capture, so command_exec lost every /say line
("[Player] relative dimension", the h154 function's "[Pig] H154
fallthrough") and failed parity-main at ebcfa2263a.
When a guest's command is captured, the broadcast now skips that guest
and the line stays in the capture, in order with the other output, which
is delivered to them as before. The console path is unchanged.

ThreadedLevelLightEngine runs the checkBlock tasks a /fill queues at most
1000 per update. command_reinforcements fills ~100k blocks around its room

vanilla side still read the old light (7, 9, 10 at different positions),
which failed parity-main and 7 of its bisect steps back to 11-05 merges.
The light op now waits for waitForPendingTasks on that chunk, ticking as

🤖 Agent: a copper chest someone has open now skips its weathering step (WeatheringCopperChestBlock.randomTick checks getEntitiesWithContainerOpen); random_tick and random_tick_sections harnesses passed.
🤖 Agent: using items (fishing rod, ender eye…) now posts vanilla's item-use game events through causeUseVibration, so sculk sensors react as in Java; sculk, server_player_sculk, server_wool_vibration and use_item_on pass against the 26.3 oracle in the gate's harness run (242 selected; failures were host setup only plus the lunge_motion timing flake).
🤖 Agent: crafting with a merchant result slot now fires vanilla's merchant crafted trigger and updates the trade, checked by the new --merchant-crafted-fixture in command_exec; merchant_crafted, command_exec and trading pass against the 26.3 oracle in the gate's harness run (242 selected; failures were host setup only plus the lunge_motion timing flake).
🤖 Agent: item entities, armor stands and boats now save the shared Entity flags (Invulnerable, CustomNameVisible, Silent, NoGravity, Glowing, HasVisualFire, Tags) as vanilla's saveWithoutId does. Its 242 selected harnesses ran on main + this head + #11017 + #11022: save_roundtrip, world_reopen, entity_nbt_boolean, the armor stand and boat ones pass; the only failures are setup (no sound/lang assets on the host, harness args) and the known lunge_motion tick-timing flake under software rendering.
MinecartTNT.tick reads the delta after AbstractMinecart.tick. The move
zeroes the blocked axes and no track step puts them back, so a cart
stopped head-on by a wall on a straight rail does not blow up, while one
glancing off a wall keeps its free axis and does, on or off its rails.
Horizon kept the speed the cart asked for before the move on the rail
paths and none off them.

🤖 Agent: overflow honey now leaves through Player.drop (eye height − 0.3, thrown along the view, pickup delay 40) instead of popping at the feet; held_drop harness passed, plus Game tests for Peaceful anger and event 2011.
HoneycombItem.useOn gives a double chest's other half its game event and
particles and plays a second sound from the clicked block, on the server and
in the client's prediction. The wax sound leaves out the acting player and
goes out in the blocks source.
WeatheringCopperChestBlock.randomTick skips the attempt, and its draw, while
getEntitiesWithContainerOpen has anyone: a player's menu, or a copper golem
(CopperGolem.hasContainerOpen), a double chest counting for both halves.

MobEffectInstance.Details nests the instance an effect hides under

same code.

The row said layers from loot are not set and no vanilla table uses the
function; a datapack table does, and the row now names the arm and the item-side
parse that puts the layers on the banner.
The loot table test fills a chest with a white banner through set_components
(a red stripe at the bottom) and then set_banner_pattern with append: the
component carries both layers, in that order; with append false it carries only
the function's blue border. Without the arm the append case keeps the single
red layer.
The item test hands set_loot_component a banner_patterns list and reads
`banner_patterns` back as two BannerLayers (pattern and dye), and a null
component empties them again. Without the arm the list is empty - the banner
wears nothing.
set_loot_component only knew the trim, so a rolled banner_patterns list landed
in `other` as a raw tag: the renderer and the tooltip read
`StackData::banner_patterns`, which stayed empty, and the banner from a
datapack table (or a set_components function) came out undyed. The arm parses
the component with the same `layers_from_nbt` the item's own component uses, so
the layers - pattern and dye - reach the fields the game reads.
SetBannerPatternFunction sets the stack's banner_patterns to the function's
layers, or with append adds them to the end of the component's own list
(BannerPatternLayers.Builder.addAll twice). A layer is a pattern id and a dye
name, so the list the table wrote is the component's list as it stands. The arm
was missing, so a datapack's banner pattern changed nothing: the banner came out
bare, or with only the layers an earlier function wrote.
apply names the ListOperation helper its four lists go through, and run names
the arm that draws the floats and colours and keeps the component the stack
already had. The rows said "no vanilla loot table uses it", which was true but
not a reason for a table that does to change nothing.
A table writes custom_model_data through set_components (floats [1.0], strings
["old"]) and then set_custom_model_data: floats appended from a constant
provider, flags and strings replaced, a colour inserted first. The rolled stack
carries 1.0 and 2.0, [true], ["new"] and [16711680] - without the arm the
component keeps the first function's lists and has no colours at all.
The helper's own test covers what a table rarely reaches: a replace_section of
one element, one with no size (the new values' length), an insert past the end
that changes nothing, and a mode the codec would refuse reading as a
replacement.
SetCustomModelDataFunction reads the stack's custom_model_data (EMPTY when it
has none) and replaces each of its four lists the function names - floats and
colors from number providers drawn with the loot random, flags and strings as
written - by that list's ListOperation over what was there: replace_all,
replace_section (offset and an optional size), insert at an offset, or append.
The arm was missing, so a datapack's model data changed nothing at all.
ListOperation itself is a small helper beside the number readers; an offset
past the end leaves the list as it was, as vanilla logs and ignores it there.
The component then reaches the item through set_loot_component's generic arm,
which keeps it in `other` where the model selection, the CIT rules and the LAN
sync already read it - that half needed nothing new.
WeatheringCopperChestBlock.randomTick runs changeOverTime only when the
chest's getEntitiesWithContainerOpen is empty, so an open chest neither
oxidizes nor draws its odds (part of #11378).

The row said no vanilla loot table uses set_book_cover, so nothing was missing;
a datapack's table does reach it, and it now names the arm that applies the
cover and the item-side parse that reads the component back.
The loot table test fills a chest with a written book through two modifiers: one
set_components with a title, author and page, then set_book_cover with another
title, an author and generation 2. The cover replaces the title, author and
generation, and the page the other function wrote is still the book's. Without
the arm the component keeps the first title.
The item test hands set_loot_component a written_book_content as the loot engine
builds it and reads the book back: title, author, generation and both pages, and
a null component leaves none. Without the arm the book has no content at all.
A component a loot function writes goes through StackData::set_loot_component
when the rolled stack becomes an item, and only the trim had an arm: a written
book's content landed in `other` as a raw tag nobody reads, so set_book_cover
(or set_components) titled a book whose tooltip and reading screen still showed
nothing. The content is now parsed the way the item's own component is - the
parse moves out of from_nbt into written_book_from_tag, shared by both - so the
title, author, generation and pages come out of a rolled book.
SetBookCoverFunction updates the stack's written_book_content, over the
component it already carries: the title as a Filterable (the raw text, and the
filtered text when a server filtered it), the author, and the generation, while
the pages and the resolved flag stay as the earlier functions left them. A loot
table's written book got none of that: the modifier ran and changed nothing, so
a datapack book came out with no cover at all.
Without a keychain, account-secrets.json was sealed under SHA-256 of a
constant and /etc/machine-id, which every local user can read; on a
system with none of the machine-id files the key was a constant built
into every launcher. Only the file's 0600 mode protected the Microsoft
refresh token inside, so a copy restored with wider permissions, or a
shared home, gave it away.
Format 2 (HZSECv2) adds a random 32-byte install secret to the key,
kept beside the file in account-secrets.key (0600, made at the first
write through a temporary file and a rename, under the file's lock).
The key is never the bare constant any more, and a v2 file whose
secret is missing or belongs to another install is refused like any
unreadable file, never written over.
A file sealed by an older launcher (HZSECv1) is still read with the old
key and sealed again under the new one at once.

A connection's network thread hands every play packet to the hub over
an unbounded channel. The hub's inbox caps (INBOX_LIMIT packets,
INBOX_BYTES bytes) apply only as it drains that channel at the start of
a tick, so while one tick runs long (an autosave, chunk generation) a
client can queue tiny packets without bound, each a boxed Serverbound
many times its size on the wire.
Each connection now counts what it handed the hub and the hub hasn't
taken yet (Undrained, shared between the network thread and the
guest's PlayerSender). Past twice the inbox caps the network thread
disconnects the client with the same message as the packet-rate kick
(disconnect.exceeded_packet_rate) and logs a warning; the hub
uncounts each packet as it takes it. A client within the inbox caps
never comes near.

cargo audit flagged two crates in the locks:
- tokio 1.53.2 (RUSTSEC-2026-0386), reached through quinn in
horizon-mod-deps and in the launcher's lock. Patched in 1.53.3, a
patch release, so both locks move there.
- lru 0.16.4 (RUSTSEC-2026-0253), reached only through mysql 27 in
horizon-mod-deps. No 0.16 release carries the fix; mysql 28 depends
on lru 0.18, which does, so the crate mods may use moves to mysql 28
(mysql_common 0.37, pem 4, base64 0.23 and arc-swap come with it).
`cargo check -p horizon-mod-deps --features mysql` builds, and cargo
audit no longer reports either advisory. A native mod that asks for
`mysql = "27"` now has to ask for 28, since the lock is the allow list;
docs/native-mods.md names the new version.

Guest break refusal is the sequence ack every PlayerAction arm sends, the packet rate limit is PacketRate::received,
and MinecraftServer.shouldRun has no haveTime budget to defer against in Horizon's loop.
neutralise breaks @mentions, #123 and github.com/ issue links in what
people write in the website's report form, so an anonymous report can't
put backlinks on the repository's issues. GitHub also links GH-123
(either case) to issue 123, which got through.
- At the start of a word, GH- followed by a digit gets a zero-width
space after GH, the way @ and # already do: the text reads the same

Two ways one client could lock every user out of the Play with Friends
relay, with no account:
(a) The only connection cap was global (4,096), counted before anything
is read, and each connection may stay silent for the 10 s first-line
wait: about 410 idle connections a second from one address kept the
relay full, so hosts couldn't register and guests couldn't join.
(b) Every join, known code or not, is refused while the global
unknown-code budget (120 a minute) is empty. Each /64 may try 5
unknown codes per 10 minutes, so ~240 /64s keep it empty, and one
residential /56 has 256 of them.
- Limiter::open_connection / close_connection: connections open at
once per address key (IPv6 /64; a /48 four times as many), 64 by
default (RELAY_MAX_OPEN_PER_ADDRESS; a host keeps one connection per
guest, hence the margin). Counted before anything is read, or right
after the PROXY line behind the PROXY protocol; past the cap the
connection is closed at once, not held for the first-line wait. An
RAII OpenSlot gives the place back however the connection ends.
- Each site (IPv4 /24, IPv6 /48) has its own unknown-code budget, 24 a
minute with a burst of 6, checked before the global one and spent on
every unknown code, so emptying the global budget takes many sites,
not one home.
- docs/play-with-friends.md: the new setting and the site budget.
- Tests: the per-address cap (IPv4, IPv6 /64 and /48, off without
per-address limits), the per-site budget (shared within a /24 and a
/48, refilling), and a running relay closing a fifth silent
connection at once with a cap of 4, then letting new ones in once
the held ones go.

The row said the name-based stats file is not moved to the uuid file. It names the function that
does it, and the segment rule that decides whether vanilla would look for it at all.
The test works in a temporary world folder: nothing is written when there is nothing to move, the
`players/stats/<name>.json` file lands on the uuid name and is not left behind, a uuid file that
already exists wins and leaves the old file alone, and the segment check refuses capitals and
separators while accepting a lowercase name with dashes, dots and digits.
PlayerList.locateStatsFile: the stats file is `stats/<uuid>.json`, but a version that wrote
`stats/<player name>.json` left its numbers under the old name. When the uuid file does not exist
yet and the name is one vanilla would write as a path segment
(FileUtil.isValidPathSegment: `[-._a-z0-9]`, and not `.` or `..` — the check is on
`<name>.json`, so a capital letter in the player's name refuses it), the old file is moved to the
uuid name and that is the file that is read; a failed move leaves the old one in place.
Horizon always resolved the uuid path, so a world opened after such a version started with empty
stats. The 26.3 advancements file has no name-based form (`PlayerList.getPlayerAdvancements`
resolves the uuid directory directly), so only stats move.
Pack::read preallocated from a zip entry's declared size and inflated it
with no limit. Shader packs are zips players download, so a deflate bomb
(or a forged size field) in any file under shaders/ aborted the game
with an allocation failure as soon as shaders.properties was read: 512
MiB of spaces zip to 509 KiB and took peak RSS from 4 to 516 MiB; at
1.5 GiB the review measured 1,543 MiB.
- Nothing is allocated from the declared size; a file that declares or
inflates to more than MAX_FILE (64 MiB, far above any .properties,
.lang or GLSL file, with room for the largest textures) reads as
missing, like a file the pack doesn't have. The same pack now stays
at 4 MiB.
- Folder packs are unchanged (files on disk, not inflated).
- Test: a small zip whose shaders.properties unpacks past a 16 KiB cap
reads as missing; the rest of the pack still reads.

a few in parallel could get it OOM-killed.
- Each entry is read with room for no more than what is left of
MAX_TOTAL (and its own 1 MiB cap), and refused as soon as it passes
it: "the pack is over 8 MiB", or the file named when it alone is over.
The same package now peaks at 6 MiB.

jigsaw, as does minecraft:jigsaw itself; a monument, stronghold or jungle
temple piece (OMB, SHCC, TeJP) comes back as nothing so the start keeps the
generator's rebuild, and so does a tag with no id or one that is not a
compound. With the table narrowed to minecraft:jigsaw alone the first four
fail.
PiecesContainer.load maps four piece ids - minecraft:nvi, minecraft:pcp,
minecraft:bastionremnant and minecraft:runtime - to minecraft:jigsaw before it
looks the type up: a save from before those pieces were jigsaw wrote them under
the older names with the same pool-element tag. The saved-start reader only
took the literal minecraft:jigsaw id, so such a start fell through to the
generator's rebuild of its chunk, and where that rebuild makes a different
layout (a world whose structure data or version moved on) the start came back
with no pieces at all: nothing placed, nothing bearding the terrain.
saved_piece_id now holds that rename table for the reader; a piece of another
type (a monument's or a stronghold's, whose NBT is not a pool piece's) still
sends the start to the rebuild.
The service sends settings like {"name":"hardcore","value":false},
a JSON bool where the DTO says string; Gson's JsonPrimitive.getAsString
accepts it, serde did not, and the detail answer the Worlds and Players
tabs need failed to parse.

Ports EnvironmentAttributeSystem: every attribute is its default run
through layers in the order they are added, leading constant layers folded
into the base (bakeLayerSampler) and the result sanitized. The dimension
type's attributes are constant layers; the biome layer reads the biome at
the position, or for spatially interpolated attributes the
SpatialAttributeInterpolator mix that GaussianSampler accumulates; the
weather layers (WeatherAttributes.RAIN and THUNDER) blend by the rain and
thunder levels with each type's state-change lerp. Timelines plug in as
time layers and come next; nothing in the game uses the stack yet.
Entries of types not ported yet (append, overlay) are kept as no-ops so a
biome's other attributes still load.
The new harness environment_system compares 900 stacks with the pinned
client (36,000 lines), with the vanilla biome and dimension type data.

`tools/port_map/game2-004.tsv` recorded
`Vindicator.addAdditionalSaveData` as `missing` and `Vindicator.setCustomName`'s
gap as "the Johnny goal reads the current custom name each tick; vanilla latches
the flag once a name is Johnny". Both rows now name what the port does, with a
row for `readAdditionalSaveData` beside them.
`vindicator_server_ai_step` is the AI step, and `mob_to_nbt`/`mob_from_nbt` are
the pair `Game::mob_tree_nbt` and `Game::load_mob` go through. A vindicator
named Bob is not Johnny; named Johnny it is; renamed to Bob it stays Johnny.
The save writes `Johnny: 1b`, the reloaded vindicator is still Johnny with the
name Bob, and a compound with no `Johnny` (its `CustomName` reading Johnny)
loads false and saves `Johnny: 0b`.
Without the latch the test stops at the first name: `left: false`, `right:
true`.
`Vindicator.setCustomName` latches a flag the first time the name it is given is
`Johnny`, and nothing ever clears it:
public void setCustomName(@Nullable Component name) {
super.setCustomName(name);
if (!this.isJohnny && name != null && name.getString().equals("Johnny")) {
this.isJohnny = true;
}
}
`VindicatorJohnnyAttackGoal` starts for `isJohnny` (`addAdditionalSaveData`
writes it, `readAdditionalSaveData` reads it back with `getBooleanOr("Johnny",
false)`), so a vindicator renamed from Johnny to Bob keeps attacking every
living entity, and one whose save says `Johnny: 1b` does so after a reload.
Horizon read the live custom name in the goal's `when` each tick and saved no
flag, so a renamed vindicator stopped attacking everything, and a reloaded
vindicator that had been named Johnny but is now Bob never started.
`extra.johnny` is the latch, taken from the live name in
`vindicator_server_ai_step` (the AI step is where a name set since the last step
is seen, and it never clears), read by the goal, written as `Johnny` and read
back from it. A save with no `Johnny` loads false, whatever the name in the
compound, as `getBooleanOr` does.

Without the change the first reads `Err(InvalidData, "external chunk stub has
inline data")` and the second `Err(Os { code: 2, kind: NotFound })` instead of
the 4000 bytes in `c.-32.0.mcc` and an absent chunk.
`RegionFile.getChunkDataInputStream` never trusts the stub's length once the
external flag is set: `streamLength != 0` only logs "Chunk has both internal and
external streams" and the stream comes from the `.mcc`. When the `.mcc` is not a
regular file, `createExternalChunkInputStream` answers `null`, so the chunk is
absent. Horizon refused both: a stub that also declared inline data failed with
"external chunk stub has inline data", and a stub whose `.mcc` was gone failed
with a `NotFound` io error, which aborts a reader where vanilla skips the chunk.

PlayerPredicate.matches calls FoodPredicate.matches on the player's
FoodData: the food level in `level`, then the saturation, a float

PlayerFacts now holds the food, always filled (two numbers), for the
player in place and for a server's other players, and player_facts tests
it after the level, as vanilla does.
The command_exec harness gets a group that fills and drains the player's

Both cases read the emitted tag, so they fail on the live palette: 342 longs
of `data` where vanilla's `SimpleBitStorage(4, 4096)` is 256, a palette of
`[0, 1, … 16]` where first use is `[1, … 15, 0]`, and `(2, Some(256))` where a
section edited back to one state is `(1, None)`.
`PalettedContainer.pack` re-encodes the cells into a fresh palette before a
section is written: a state no cell holds any more is dropped, the entries are
in first-use order, and the bit count is `getConfigurationForPaletteSize` of
the states that remain. `PalettedContainer::to_nbt` wrote the live palette
instead, which keeps the slot of every state a block edit replaced (the `free`
list needs it) and packs at that wider count: a section whose 17th state was
edited away saved 342 longs where vanilla writes 256, and a section edited back
to a single state saved a 2-entry palette with a 256-long `data` where vanilla
writes one entry and no `data`.
Play in Background, off by default and per player, lets the pad keep driving the game while its
window has no focus, and a game the pad is playing doesn't pause on losing focus.
While several play, the router now plays each player's rumble on that player's pad. Rumble no
longer stops when the window loses focus: nothing asked for that, and it's useful to an AFK player.
Starting or leaving splitscreen builds a new renderer, whose atlas has none of what was drawn into

things.

`tools/port_map/animal-1.tsv` had no answer for
`Armadillo.addAdditionalSaveData` or `Armadillo.readAdditionalSaveData`. Both
now name `entity_nbt::mob_to_nbt` / `mob_from_nbt`: the state written as its
`ArmadilloState` name beside `scute_time`, and read back through
`switchToState`, idle when the save names none.
`mob_from_nbt` and `mob_to_nbt` are the pair `Game::load_mob` and
`Game::mob_tree_nbt` go through. An armadillo whose save names
`state: rolling` loads rolling and takes 4.5 of a hit for 10; six ticks into
the roll its shell is out; a save that names no state, or a name that is no
`ArmadilloState`, loads idle and takes the whole 10. Saving a rolling armadillo
writes `rolling` even when the compound it came in with said `idle`, and the
reloaded one has its time in the state restarted, so the shell is not out until
it has been rolling for six ticks again.
Without the state in the pair the loaded armadillo is idle (left: 0, right: 1)
and takes 10 for a 10 hit where it took 4.5 rolled up.
`Armadillo.addAdditionalSaveData` writes the state the armadillo is in beside
its scute timer, and `readAdditionalSaveData` switches to it:
output.store("state", Armadillo.ArmadilloState.CODEC, this.getState());
output.putInt("scute_time", this.scuteTime);
...
this.switchToState(input.<Armadillo.ArmadilloState>read("state", Armadillo.ArmadilloState.CODEC)
.orElse(Armadillo.ArmadilloState.IDLE));
`ArmadilloState.CODEC` is a `StringRepresentable.fromEnum`, so the key holds
`idle`, `rolling`, `scared` or `unrolling`; `switchToState` sets the synched
state, and `onSyncedDataUpdated` restarts `inStateTicks` when it changes.
Horizon models the same state (`extra.armadillo.state`, the value
`Armadillo.getState` is synched with) and wrote only `scute_time`, so an
armadillo that unloaded while rolled up came back idle: a hit for 10 went from
4.5 back to 10.0 (`Armadillo.hurtServer`: a ball takes half of the damage past
the first point), `hiding_in_shell` went false so the model lost its shell, and a
brush or a food click was answered by an idle armadillo instead of a ball.
`state` is now written from the live state - `idle` for one that is not rolled
up, as vanilla writes it unconditionally - and read back through `set_state`,
which is `switchToState` plus `onSyncedDataUpdated`: a save that names no state

the state starts again at 0.
The command-execution furnace family could not give a checkable gap control
on this host, so this is a direct AbstractFurnaceBlockEntity.serverTick
harness instead: a real RecipeManager and a furnace, blast furnace or smoker
in a block-update level, compared with FurnaceCooking::tick. It pins the
cooking_fuel burn table for every fuel item, the 200/100/100 cook times and
speed multiplier, fuel consumption and LIT state, RecipesUsed experience, a
full output slot, timer decay, and an input changed mid-cook. --no-change
reproduces the corpus before that family.

DropperBlock.dispenseFrom finds its target with HopperBlockEntity.getContainerAt:
the block's container, else a container entity (chest boat or raft, chest or
hopper minecart) whose box meets the space in front, picked at random. Horizon's
dropper only asked for a block container, so items fell out next to a chest boat
instead of going in. It now falls back to the entity lookup hoppers already use.
The dispenser harness gains 48 dropper cases with chest boats, rafts and chest
and hopper minecarts centred in front, reaching in from beyond, just past the
space, two at once, behind a chest block and non-container vehicles. The oracle
and the fixture print the container entity's items (Tinv lines).

`tools/port_map/game2-002.tsv` recorded `gap: minor: anchor_pos is not read` and
`not written` for `Phantom.readAdditionalSaveData` and
`Phantom.addAdditionalSaveData`. Both now carry the anchor and say how: the key
only for a phantom that has an anchor, absent or unreadable as no anchor.
`mob_from_nbt` and `mob_to_nbt` are the pair `Game::load_mob` and
`Game::mob_tree_nbt` go through, so the test loads and saves a phantom by its
compound. A phantom at (0.5, 75, 0.5) whose save names `anchor_pos: [100, 64,
-40]` loads with that anchor, circles to (109.66, 62, -37.41) - the anchor,
`distance*cos(angle)` across and `-4 + height` up - and a phantom that moved its
anchor to (9, 70, -3) saves that position, not the one its compound came in
with. A phantom with no anchor loads with none and saves no `anchor_pos`.
Without reading the anchor the load gives the phantom (0, 80, 0), its own
position five blocks up, and the circle point (9.66, 78, 2.59); without writing
it the save keeps the stale (100, 64, -40).
`Phantom.addAdditionalSaveData` writes the anchor the phantom circles around
beside its size, and `readAdditionalSaveData` takes it back:
protected void readAdditionalSaveData(final ValueInput input) {
super.readAdditionalSaveData(input);
this.anchorPoint = input.<BlockPos>read("anchor_pos", BlockPos.CODEC).orElse(null);
this.setPhantomSize(input.getIntOr("size", 0));
}
protected void addAdditionalSaveData(final ValueOutput output) {
super.addAdditionalSaveData(output);
output.storeNullable("anchor_pos", BlockPos.CODEC, this.anchorPoint);
output.putInt("size", this.getPhantomSize());
}
Horizon models that anchor in `extra.home`, which
`PhantomCircleAroundAnchorGoal.selectNext` centres the circle on
(`anchor + (distance*cos(angle), -4 + height, distance*sin(angle))`), but
`mob_to_nbt` wrote only `size` and `mob_from_nbt` read only `size`. A phantom
saved and reloaded therefore kept the anchor `register` gives every new phantom
- its own position five blocks up, vanilla's `finalizeSpawn` value - instead of
the one in its save: a phantom at (0.5, 75, 0.5) loaded with
`anchor_pos: [100, 64, -40]` came back anchored at (0, 80, 0), and its first
circle point was (9.66, 78, 2.59) rather than (109.66, 62, -37.41).
`TagValueOutput.storeNullable` writes the key only for a non-null value, and
`read(...).orElse(null)` gives null for a save without one, so a phantom with no
anchor now writes no `anchor_pos` and loads back with none - the circle then
fills it with its own `blockPosition()`, as vanilla's does.
The brewing suite stopped at recipe matching, assemble and the slot filters;
nothing advanced the block entity. The tick family now runs the real
BrewingStandBlockEntity.serverTick and BrewingStand::tick for 0..8001 ticks
and compares slots, brew time, total brew time, fuel, total fuel, speed,
bottle bits, ingredient and the brew-event count. It covers the 400-tick brew
divided by speed_multiplier and its ceiling (2, 3, 0.3 and 0), blaze powder's
twenty uses and speed 1, fuel loaded with nothing to brew, splash and
lingering outputs, ingredient shrink and mismatch, finishing without fuel and
twenty brews from one blaze powder. --no-tick leaves the tick corpus out.

player-expect is refused as "the server is full" once the places the
player limit counts and those of the other expected players reach
max-players: each expectation holds a place, so two proxies sending
players at once cannot fill a server past its limit. As at login, an op
who bypasses the limit is never refused, and a renewal holds no second
place.
Once a stop has begun (/stop from the console, a player or the control
endpoint, or a stop signal), player-expect, player-import and
player-confirm are refused as "the server is stopping": a player must not
arrive on a server that is about to close. A retry after the commit is
still answered, and export, release and drop stay open, since they are how

The knee eases HDR lighting's gain into the peak; light written as light (alpha 1) has no

screenshot-sequence FRAMES STEP_MS PATH, under HORIZON_STILL with the world

Sequence frames are submitted inline and waited for on the GPU, so each

that would change the scene while it runs, and ends with an error when the

Now every job runs and only the first refusal is recorded, so the

- An idle pad's trigger rests at -1, which counted as moved past 0.5, so touching

`build_surface_shared` applies the compiled rule at every solid block of a
column. In the Overworld most bands specialise to "the ore veins, then one
block" (deepslate), so 1.7M rule applications per 64 chunks produce ~1M block
writes, each walking the rule tree from the top and going through
`set_block`/`set_block_worldgen_column`.
A band variant that is a block rule, or ore veins followed by one, gives that
block at every position where no vein places one. The walk now writes the whole
run of solid blocks at once: the top y through the single-block path, the rest
through `TerrainChunk::fill_solid_run`, stopping at the first y where a vein
can place a block (each vein's first test, its density), at the band's bottom
and at the write bounds. Only blocks that are opaque for the stage's heightmaps
and carry no fluid take this path, so one update at the run's top leaves the
maps as a write per block does.
`CompiledRule::apply` on a sequence also tests its conditional children in the
loop instead of through a recursive call.
Instructions (callgrind, proto phase, 64 chunks, seed 12345): Overworld
6.49 G -> 6.03 G (-7.0%), surface stage 1.98 G -> 1.53 G (-23%), rule
applications 599 M -> 329 M; Nether 2.97 G -> 2.73 G (-8.1%).

Most NBT strings in a saved chunk (names, ids, compound keys) are ASCII.
The reader decoded modified UTF-8 one byte at a time and the disk writer
put every unit through its own limit check. Now an all-ASCII string is
widened in one pass when read, and a string whose units are all one byte
(1 to 127) is written in one extend when it fits under the byte limit;
anything else takes the old per-unit loop, so the bytes and the error
offset are unchanged. A new test checks ASCII, zero, mixed and non-ASCII
strings against a per-unit reference and the limit's error offset.
While the dragon fight's world fog leaves out the End's sky, Iris 1.11.7 still

a fan around the horizon: from (0, -16, 0) under the eye to eight rim points 16
above it, every 45 degrees, at the render distance. Horizon ran no sky program
in the End, so packs that paint their sky there left that band empty.

The driver compiles each program of a shaders/ pack as its pipeline is made,
and a pack's pipelines were made one at a time while the pack was laid out:
Metal's compiler service sat on one core for 5 to 50 s on a big pack (BSL,
Complementary, Photon) with four others idle.
The pack is now laid out first, its pipelines recorded as jobs whose pipeline
goes in a slot of its pass, then made all at once on up to 8 threads (wgpu
keeps error scopes per thread, so each is still checked). When wgpu or the
driver refuses one, the pack is built again a program at a time, as before,
so that program is skipped with its note exactly as it was.
Cold loads on an M5 (each pack's first load, nothing in the Metal cache),

Unbound 9.0 s -> 2.3 s.

Part of #9996.
BlockSection::set and BlockSection::fill_run are 7.0% of the proto phase
in the overworld and 9.4% in the Nether (callgrind on generate_proto).
Each write located its packed word twice, and fill_run rebuilt the word
mask for every block.
PackedStorage now hands out a Slot (word and bit shift) that read_at and
write_at take, so set locates the entry once; the palette-growth branch,
which re-packs the words, looks it up again. A run in one column moves
256 entries per Y, so while a word holds a whole number of those steps
(every width generation produces) the bit shift stays the same along the
run and WordRun writes each block with one load, mask and store. Widths
that do not divide the stride go one set per block, with the same palette
edits in the same order.
Live palette slots hold distinct states (sections loaded from disk are
rebuilt through set), so "already this state" is old_id == id and "was
air" is old_id == air_id, both resolved once per call. set on a uniform
section has its own small path.
Palettes, their order, the free list, counts, the chosen width and the
packed words are unchanged: the 8 chunkgen_bench snapshot files (terrain
and decorated; overworld seeds 12345 and -1, the Nether, the End) are
byte-identical to main, and a new unit test replays random set/fill_run
sequences over every palette width against main's fill_run.
Proto-phase instructions: overworld 6.497 G -> 6.340 G (-2.41%), Nether
2.974 G -> 2.859 G (-3.84%).

`Warden.addAdditionalSaveData` stores an `AngerManagement`: a `suspects` list of
{uuid, anger} pairs, and nothing else about the anger. Horizon wrote an empty
`anger` compound and read nothing back, so a reloaded warden was calm.
`AngerManagement` now keeps the suspects that are not in the level by UUID next
to the live ones, both calming by one an anger tick, and looks the UUIDs up
again every two anger ticks through the game layer's map
(`Game::who_by_uuid`, reached from the mob layer through `MobWorld`'s new
`WhoLookup` seam). The chunk save names a suspect by its UUID, minting one for
a loaded suspect that has none yet.
A save can now name an entity it only knows as a `Who`: `mob_to_nbt` takes a
`uuid_of` resolver, `who_uuid` writes a `Who` as a UUID and `who_by_uuid` turns a
stored UUID back into the `Who` of a loaded player or mob. `EntityMemory::uuid_of`
supplies the id -> UUID map the game layer keeps, and the game layer's `mob_by_uuid`
now resolves through the same seam.
The neutral mobs' `angry_at` is the first writer: anger at another mob now saves
that mob's UUID instead of nothing. The warden's suspect list and the shulker
bullet's target are the two follow-ups this bridge unblocks; neither is written
here.
Floor floating Health values before short narrowing and preserve integer narrowing. Add an actual decode-to-save regression and an isolated Game/Java command fixture.
Co-Authored-By: Codex gpt-6.1-sol <[email protected]>
ShulkerBullet.addAdditionalSaveData writes `Target` (the UUID it homes on, only
while it has one), `Dir` (`Direction.LEGACY_ID_CODEC`, the step it is on, absent
until it picks one), `Steps` and the per-axis target deltas `TXD`/`TYD`/`TZD`,
over `Projectile`'s owner and LeftOwner; readAdditionalSaveData reads them back
and keeps `Target` as an `EntityReference` it re-resolves every tick.
Horizon's `saved_with_chunk` turned a bullet with a target away - which is every
bullet a shulker fires - and `spit_or_bullet_to_nbt` refused it too, so the chunk
save dropped the bullet, and nothing read a step or a delta back.
The writer writes those keys now, the reader reads `Dir`, `Steps` and the deltas
into the kind, and `Target` goes through the UUID bridge: `Game::save_who_uuid`
answers it with `who_uuid` over `EntityMemory::uuid_of` (nothing for a mob the
level has no UUID for, never a made-up one), and `Game::bullet_target` resolves
the stored UUID with `Game::who_by_uuid`, which names the player or a mob that is
loaded. A bullet whose target is not loaded comes back with none and falls, as
`ShulkerBullet.tick` does with a target it cannot find, rather than homing on
whatever its old id means now.
A loaded bullet's own random stream is seeded from where it is, since
`Entity.random` is not saved: the same stand-in `Projectile::new` gives an
arrow's.
A save can now name an entity it only knows as a `Who`: `mob_to_nbt` takes a
`uuid_of` resolver, `who_uuid` writes a `Who` as a UUID and `who_by_uuid` turns a
stored UUID back into the `Who` of a loaded player or mob. `EntityMemory::uuid_of`
supplies the id -> UUID map the game layer keeps, and the game layer's `mob_by_uuid`
now resolves through the same seam.
The neutral mobs' `angry_at` is the first writer: anger at another mob now saves
that mob's UUID instead of nothing. The warden's suspect list and the shulker
bullet's target are the two follow-ups this bridge unblocks; neither is written

AreaEffectCloud.addAdditionalSaveData was listed missing, which was right: only
the reader existed. game/potions.rs::potion_cloud_to_nbt writes it now, from
entity_chunks.
A cloud with a poison and a slowness effect, one of them hidden and one ambient,
written with potion_cloud_to_nbt and read back with potion_cloud_from_nbt: the
position, age, duration, radius, the four use settings, the duration scale,
RadiusPerTick, the effect list and the colour all come back. The test also
checks that the compound carries the field names vanilla's
readAdditionalSaveData looks for, and that it is saved as
minecraft:area_effect_cloud.
AreaEffectCloud.addAdditionalSaveData writes the cloud's age, duration, radius,
the four use settings, RadiusPerTick, potion_duration_scale and its
potion_contents, and the client already read every one of them back
(game/potions.rs::load_potion_cloud): a cloud that was loaded from a save came
back whole. Nothing ever wrote one, though. entity_chunks writes the dragon, the
crystals, the item frames, the fangs and the rest kind by kind, and the
lingering clouds -- which live in breath_clouds, not in entity_lists! -- were in
none of those, so every replacement pass dropped the cloud a thrown potion or a
creeper left behind.
The save side now writes them: game/potions.rs::potion_cloud_to_nbt builds the
compound on the entity fields entity_nbt::entity_base_tag gives it, and
entity_chunks adds one tag per potion-bearing cloud of the chunk. A dragon's own
breath carries no potion and is not written.
The reader moved out of the Game method into potion_cloud_from_nbt, so the pair
can be tested against itself. The client keeps no potion id, so the effects are
written as custom_effects with the colour the cloud was drawn in, and the custom
particle and owner reference the vanilla cloud also saves have no counterpart
here.
A windowless game with a jukebox at (0, 64, 0): a disc put in and popped back
out posts one G 0,64,0 minecraft:jukebox_stop_play, a song ticked to its end
posts one, a broken jukebox posts none from this path (the world's spill posts
it) and a jukebox that never held a disc posts nothing.
JukeboxSongPlayer.stop posts GameEvent.JUKEBOX_STOP_PLAY at the block (and level
event 1011), and both ways a song ends reach it: popOutTheItem, when the disc is
taken out or a hopper pulls it, and tick's own hasFinished branch.
Horizon posted that event only from the world's removal path, so a broken
jukebox was heard but a jukebox whose disc was pulled out by hand, or whose song
ran out, was silent to a sculk sensor beside it. The paths that keep the block
now go through stop_song_heard; jukebox_removed keeps the plain stop_song,
because the world's spill already posts the same event once for it.

Killing an entity that is no mob posts ENTITY_DIE (frequency 15) at the
entity, as vanilla's kill paths do: BlockAttachedEntity.kill (cushions
punched, burnt, unsupported, struck or blown up; paintings; empty item
frames), ArmorStand.kill (broken, burnt out, blown up, /kill's
generic_kill), VehicleEntity.destroy (boats and minecarts, not a creative
hit, which only discards them) and Entity.kill from /kill for the other
non-living kinds. The attacker is the source when a hit kills it
(attributedTo), otherwise the entity itself. A frame holding an item only
gives the item up and does not die (ItemFrame.hurtServer). The event runs
on the server's path, so single player, LAN guests and dedicated servers
all get it.

AgeableMob.isBaby is now a row of its own pointing at Mob::is_baby, which is
`can_be_a_baby && getAge() < 0`; canBeABaby points at
species::can_be_a_baby, and the six classes that override it to false carry a
row each so the false arms are not read as unported.
living.rs::a_negative_age_is_a_baby_only_where_can_be_a_baby_allows_it drives
Mob::new on the loading table's own types and sets Age to -24000, the
BABY_START_AGE a save or a /summon carries, then asks is_baby, dims and
voice_pitch - the three the game draws and hears from.
A parrot, a tadpole, a frog, a zombie nautilus, a camel husk, a slime, a magma
cube, a piglin brute and a creeper keep their type's box (the tadpole 0.4 by
0.3, the camel husk 1.7 by 2.375, the piglin brute 0.6 by 1.95) and voice at
1.0 ± 0.2. The control is a cow at the same age: is_baby true, Cow's
BABY_DIMENSIONS (0.45 by 0.7, eyes at 0.69) and 1.5 ± 0.2, and an adult box and
voice again at age 0. With is_baby back to `age < 0` the test stops at the
parrot.
entity_nbt's save test now runs a frog and a camel husk beside the slime, the
magma cube and the pig: the first four write no Age and keep none of a raw
compound's Age, the pig writes its modeled -37.
AgeableMob.isBaby is `canBeABaby() && getAge() < 0`, and canBeABaby is true
across the ageable tree but for the six classes that override it to false:
Frog, Parrot, ZombieNautilus, CamelHusk, Slime and MagmaCube (an
AbstractCubeMob is an AgeableMob). Everything outside that tree inherits
LivingEntity.isBaby's false, so a Giant, a Creeper, a PiglinBrute (it extends
AbstractPiglin and declares no isBaby of its own) and a Tadpole, whose own Age
runs up from -24000, are never babies either; only the zombies, the piglins and
the zoglin answer a synced DATA_BABY_ID instead of an age.
Mob::is_baby read `extra.age < 0` alone. The list of who can be a baby existed
already, but only as mobs::drops::can_be_baby, which gates the metadata baby
flag and the loot table: the box, the voice, breeding, growth and the goals
read the age and so called a frog, a parrot, a creeper or a tadpole with a
negative Age a baby. The list is now species::can_be_a_baby, on the species
table, and is_baby is `can_be_a_baby && age < 0`.
What that changes: a tadpole (Age -24000, its own DEFAULT_AGE) is drawn at
getAgeScale's 1.0 instead of 0.5 and speaks at 1.0 ± 0.2 instead of 1.5 ± 0.2,
as vanilla does; a parrot, a frog, a zombie nautilus, a camel husk, a slime, a
magma cube, a piglin brute, a creeper or anything else the table cannot make a
baby keeps an adult's box, voice, breeding, growth and drops. The Parrot arm of
voice_pitch was there for the same reason and is dead now: Parrot.getVoicePitch
is `getPitch(random)`, the plain range an adult already gets.
AgeableMob.addAdditionalSaveData writes Age only when canBeABaby, and the
branch that drops the values a raw compound carried named four classes by hand;
it asks the ageable table now, which also covers the frog and the camel husk
that were re-saving an Age vanilla writes for neither.
Record a marker only for Nightlies installed by automatic updates. Keep
manual and legacy Nightlies out of GUI and CLI cleanup, while retaining
the newest managed Nightlies separately from game releases.
Add regression coverage for manual, legacy, selected and pinned builds.

The Worlds tab's Backup button now opens RealmsBackupScreen: a row per automatic backup
with its date (mco.backup.entry), Restore per row, and Back. A row opens
RealmsBackupInfoScreen: the backup's metadata as translated key/value rows
(mco.backup.entry.<key> when the language has it). Restoring asks nothing (vanilla's
Restore button restores at once) and the list reads again when it is done.
RealmsClient gains backupsFor (GET worlds/{id}/backups) and restoreWorld
(PUT worlds/{id}/backups?backupId={id}, vanilla's 40 s/600 s timeouts), with Backup's DTO
(backupId, lastModified, size, metadata, changeList). The backup id goes into the query
percent-encoded, so it cannot add a parameter.
Download Latest still needs the download-and-unpack flow and is left for its own PR; the
rows show the date and the metadata screen the details (size included).

The GUI runs the shared pruning path after saving its selection, but its

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).

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

## Performance
**Horizon draws more frames per second than Java Edition, and loads faster, on the same machine, world and path.**`tools/perf_bench.py` runs each game in turn, from a fresh world (seed 1234), waiting for the terrain and then flying it over a village, a forest, an ocean and a mountain. Measured on 2026-10-29/30 on an idle Windows 11 machine (Ryzen 7 9800X3D, RTX 5080), Horizon v0.2.97 as the launcher installs it, 1280x720 in a window, VSync off, three games per figure. Frames per second, mean of the four scenes, with the slowest 1% of frames in brackets:
"Vanilla + mods" is Sodium, Lithium, FerriteCore and ImmediatelyFast. Horizon reaches the title screen in 2.9–3.2 s against vanilla's 7.5–7.7 s (the modded client's 10.8–11.1 s), loads a scene's chunks 2.9–3.8 times faster, and playing holds a steady working set of 1.1–1.7 GB against 1.9–2.9 GB. Every scene with its confidence interval and the run's load log: [the 2026-10-29 reports](benchmarks/perf/windows-9800x3d-5080-2026-10-29.md). Method, and how to measure your own machine: [docs/benchmark.md](docs/benchmark.md). [playhorizon.dev/benchmarks](https://playhorizon.dev/benchmarks) puts these runs beside a 2016 laptop, a Mac mini and a gaming desktop.
