🤖 Agent: the client keeps only the server's attribute modifiers, so Speed now ends one tick after RemoveMobEffect as in vanilla (ServerPlayer.doTick runs after sendDirtyEntityData); Paper+GrimAC bench 7-17 Simulation flags at expiry -> 0, 8 selected harnesses pass.
🤖 Agent: verifies the per-mod-set build signature with its own Ed25519 key (separate from the release key) before the launcher runs a prebuilt binary; independent review found it sound; opt-in stays off until the rollout steps.
🤖 Agent: the default build resolves the same features as before (390 third-party units with identical fingerprints); every new gate is cfg!(), so CI's existing --no-default-features clippy already compiles the no-extras side and no stub can drift.
with_vault built the list of every player (lan_present: eye heights, effects,
omens) for every loaded vault every tick. VaultBlockEntity.Server.tick reads the
players only when the vault's state may change (stateUpdatingResumesAt, once a
second), so the list is now built at the first ask, from the same game state.

🤖 Agent: item components read by reference instead of cloned per frame (frame prepare 217→193 µs); earlier parity failures were harness bugs since fixed on main; parity-main covers it after merge.
🤖 Agent: HUD glint sprite looked up once per item instead of per quad (HUD 84→72 µs); render-only, packet harness 16/16; parity-main covers it after merge.
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.

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.

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.

They now skip entities outside entity-ticking chunks and keep the portal

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.
- THIRD_PARTY_NOTICES.md: an fdlibm section.
Bit for bit against JDK 25: StrictMath log, log10, cbrt and hypot on
2.5M, 2.5M and 2.7M inputs and 5.9M pairs; Math.sin and Math.cos on an
Apple M4 on 3.05M arguments, compiled and -Xint; Math.round(float) on
all 2^32 floats.

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.

🤖 Agent: pictures are drawn on background threads and cached by item hash and screen scale, so the Shop never renders on the UI thread; prices and the checkout call are the same rules as before (two live checkouts cancelled via Paddle).
Entity.applyEffectsFromBlocks runs in the entity's own tick, and
ServerLevel.tick ticks only entities in entity-ticking chunks, so a mob or
item past the simulation distance presses no plate and is not hurt by a
cactus. tick_blocks swept every loaded entity: 2.5 ms a tick on the SMP,
where ~2,900 of 4,600 overworld mobs sit outside entity-ticking chunks.

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.

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
in 3D (an emote plays), with a look's items, Buy and Gift.
- Pictures: the Wardrobe's CPU renderer, framed on the item (preview::fitted_view),
at device pixels supersampled 2x, on background threads, kept by item hashes.
- 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.

Looks) in all 86 tables, nine unused ones removed.

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.
Co-Authored-By: opencode (DeepSeek V4.1 Flash) <[email protected]>
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.

(PlaceCommand.placeFeature over a ResourceOrHolderArgument value) and
reports commands.place.feature.success.inline.
The inline value is read with the existing SNBT-to-JSON pair, decoded
by the same feature codec as a named feature (feature_with_blocks,
uncached), and placed through the same Feature.place path with the
level random. A feature that does not place reports
commands.place.feature.failed; a value that does not decode keeps the
plain failure.

HORIZON_COSMETICS_CATALOGUE=<file of GET /v1/catalogue> gives the development preview
real prices, sets and collections, so Shop screenshots show what players see.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
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.

🤖 Agent: requeued at 8cd24bc4e5: the merger stopped on a main conflict, and the author's main merge resolves it. verify is green on this head; the run-parity label reruns parity on it before the merge.
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 native shader pack's sky pipeline layout declares the terrain's 10 sampled textures and the frame's 9, so it was refused at 16 although the driver accepts it (#10095).
Query GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS and GL_MAX_TEXTURE_IMAGE_UNITS, take the lower, and cap at the arrays' new 32 slots (MAX_SAMPLERS likewise). On WebGL2 the query still yields 16.

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.

Older packs write expressions in the legacy syntax: uppercase variables
(AGE, DISTANCE_SQUARED, RAIN...), pi and e, and bare rand(), gaussian()
and noise(). Each variable now runs as the scripting call the wiki maps
it to, and a legacy expression keeps the old argument order of lerp,
smoothstep and color. The color functions (red, color, withAlpha,
lerpColor, hsb, lerpHsb...) follow vanilla's ARGB channel rules, and
dist/distSquare join the math table. All expressions of Visual

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.

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,

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,

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.

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

`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.

Extend the spawn rule suite with Mob.checkSpawnObstruction: real entities
against water, lava, an obstructed level and Ocelot's special base, with
--no-obstruction reproducing the previous corpus.
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.

The pose test asserted that Temper lands in the legacy variant3 byte. #11483/#11659 move every equine's temper to the signed equine_temper field; the assertion was outside this test's subject (LastPoseTick), so drop it rather than pin the storage.

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. The camel_temper field and the camel byte-clamp path are gone; tests follow.

🤖 Agent: Native mods can draw terrain models with an explicit material (shade, UV shift); the shading follows Flywheel's (MIT, credited). Main merged in after #11117 landed; its test now builds faces with #11356's BakedFace::new (clippy -D warnings passes).
FogState now holds the torch flicker's LegacyRandom, so main's rain fog

#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.

Main added invite_public_part (horizon_friends::invite) after this branch

Main's #11661 added LevelAccess::container_open and its test for the open copper chest; this branch keeps that name and its test and drops its own container_has_viewers, folding the copper golems' chests into GameLevel::container_open.

🤖 Agent: older clients 26.1→1.20.5 behind accept_older_clients (off by default); a 26.3 client never reaches ClientSession or the components_before_1_21_6 rewrites; per-step unit tests + lan_bot joins one bot per release; doc of older_client fixed.
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
doc names the three settings screens that take the Blocks palette.

🤖 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.
🤖 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
the next world opened. Same as sync_enchantment_registries.

🤖 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
this layout; both Escape paths (mod_browser_back, close_transferred_recipe)
kept; one JEI notice for the sprites and the icon.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
The commands' minecraft:damage_type ids came from the vanilla export
alone, so /damage refused a type from a content mod or a world's data
pack with argument.resource.not_found. Vanilla's ResourceArgument looks
the id up in the server's registries, packs included.
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
guest, a player who has already loaded, and a respawn stay on the
64-column quota. Unlit columns stay withheld, the far ring still spends
only the leftover vanilla quota, and the gates that send nothing are
unchanged.
Fixes#6763
🤖 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
path runs after that count like the plain one.

🤖 Agent: code-owner approval given; pruning only touches marker-carrying Nightlies, manual/legacy ones are outside the quota (tests cover all four cases).
🤖 Agent: vanilla's CheckerboardColumnBiomeSource sets bitShift = size + 2 with no clamp, and Java's >> masks the distance; wrapping_add(2) as u32 with wrapping_shr does the same. biome_source PASS with fresh Java on the desktop (main + this head).
🤖 Agent: a map crafted from the grid gets Item.onCraftedBy on the taken stack and the scaling recipe reads the level's maps; merged with main's merchant on_take; craft_map_take and merchant_crafted pass.
The new touching_unloaded_chunk was inserted between eye_columns and its
doc comment, which then documented the wrong function.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
🤖 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.
Add a shape family over real frames and a --no-shape switch that reproduces
the previous corpus byte for byte.
The automatic pool size was every core but one. On Apple silicon the
efficiency cores count too, so a base M4 (4 performance + 6 efficiency
cores) ran 9 workers that kept the render and server threads waiting for a
performance core: fast flight's p99 frame went from 20 ms to 7 ms with 3
workers (#11294). The automatic count now leaves one of the performance
cores (hw.perflevel0.physicalcpu) instead; elsewhere it is unchanged, and
Graphics > Worker threads still overrides it.

🤖 Agent: a negative Age makes a baby only where AgeableMob.canBeABaby allows (frog, parrot, zombie nautilus, camel husk, slime, magma cube stay adults: box, voice, loot); ageable_integer_load, entity_death_loot and baby_pig_attachment pass.
🤖 Agent: Realms reset-world, templates and upload, stacked on #9982 (land after it); upload goes only to the endpoint the service returns; realms tests pass.
🤖 Agent: Realms backup list and backup info screens on main's Realms code (only the backups commit kept; the carried settings/invite copies already landed); restore asks the service and re-reads the list; realms tests pass.
🤖 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.

🤖 Agent: roadmap.toml is the source; ROADMAP.md and roadmap.json regenerated (build --check passes). older-servers kept on purpose (1.8 PvP servers), only the sign-in item goes.
Mojang's approval covers Microsoft sign-in only; other account providers
(Ely.by, Yggdrasil servers) are against the rules Horizon plays by, so the
item can't ship. #1270 stays closed.

ThreadedLevelLightEngine runs the checkBlock tasks a /fill queues at most
1000 per update. command_reinforcements fills ~100k blocks around its room
and then requires block and sky light 0 there; on a loaded runner the
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
settle does.

🤖 Agent: follow-up to #10129: with glass off, macOS still gets its 32 px title bar (plain side colour), so content no longer sits under the traffic lights.
🤖 Agent: follow-up to #10177: the unmaximize-before-fullscreen step runs on Windows only, and apply() no longer re-requests fullscreen each call while the window reports maximized.
parity.py runs a harness with no arguments; --side was required, so every
automatic selection failed it at once. The default now runs Java, then native

Raid.findRandomSpawnPos and the cached wave position both ask
ServerLevel.isPositionEntityTicking: an entity-ticking chunk in entity

🤖 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.
Part of #11380 (the impact detonation; the team push points stay open).

🤖 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
hidden_effect, and the player save writes the whole chain. Horizon wrote
only the top instance, so a weaker, longer effect (Poison I under
Poison II) was gone after a reload instead of resuming. SavedEffect is
now a struct carrying that chain; guest player data goes through the
same code.

🤖 Agent: the device list is now read on a worker thread, so a slow Windows audio driver no longer stalls a frame; the render thread only swaps in the result. No vanilla behaviour changes, no harness covers it.
RaidCommand.getRaid is getRaidAt, which returns a raid that has not
started its first wave yet. playSound plays the horn only for the text
"local", at volume 2 with the level random's seed. The status line
concatenates its floats the Java way (20.0, not 20).

- Animal.finalizeSpawnChildFromBreeding adds one new ExperienceOrb of the
parent's 1-7 roll: breeding no longer splits it (4 into 3 + 1) or merges.
- ThrownExperienceBottle.onHit awards with direction: away from the block

starts 0.25 that way and a random motion against it is turned round
(ExperienceOrb(level, pos, roughly, value)) (#11388).

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.

- 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
and links nothing. Other words (high-5, GH-pages, laugh-1) are left
alone.
- Test: GH-12, gh-7 and (Gh-8) are neutralised; look-alikes aren't.

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.

Pack::read inflated each of up to 512 zip entries to 1 MiB + 1 and kept
them all, and only Pack::from_files then checked the pack's 8 MiB total.
511 entries of zeros take 561 KiB zipped, and the mod registry reads
every submitted .hshader (index::inspect, Kind::Shader) on its blocking
pool: one upload made it hold 1 GiB (measured: peak RSS 3 -> 1,026 MiB),
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.

A cushion is an ordinary entity in vanilla (a BlockAttachedEntity), but
Horizon had no command target for it: @e never matched one, so execute

InviteCodeList.parse reads a JSON array, or an object whose 'result' is

- RealmsConfigureWorldScreen.fetchServerData replaces its serverData with
getOwnRealm's answer; the port kept the server list's copy, whose

- Request.post sends Content-Type: application/json; the frontend

PiecesContainer.load now names saved_piece_id, where the rename table lives,
and StructureStart.loadStaticStart spells out that a jigsaw start (the renamed
old ids included) comes back from its saved pieces while another structure's
start comes back from the generator's rebuild of its chunk.
A piece tag named minecraft:nvi, pcp, bastionremnant or runtime comes back as
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.

ItemModels::components cloned the item's whole default component map (an

ComponentsView reads the patch, then the defaults, with no copy; the

use animation read through it. components() stays for what needs the

es_es.json held 271 of the 894 keys en_us.json now ships, so 623 strings
(70% of the file) fell back to English on Spanish screens: the whole PvP
and HUD page, splitscreen setup and profiles, Horizon extras, the mod
browser, the resource pack browser, friends, the on-screen keyboard,
Replay Studio, the music page, cosmetics and the shader and graphics
descriptions.
This fills the table: 894/894 keys, no missing or extra ones, every
placeholder kept. The four values that were still English (Particle
Culling and its three descriptions) are translated, and the shader page
name now says "shaders" like the rest of the file.
lang.rs also serves es_ar, es_cl, es_ec, es_mx, es_uy and es_ve from this
file.

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
compared as a double, in `saturation`. The player facts carried no food
and the matcher never read `food`, so any food bounds passed.
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
food in player loops and tests named food predicates, a non-player, and
a tick advancement whose player condition asks only for food.

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

`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
(or names one that is not an `ArmadilloState`) loads as idle, and the time in
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

Since smooth() keeps going through teleports, a pack remembers whether it
has drawn a frame of the world. A reset pack now forgets that too, as a
pack just loaded has seen none.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
A pass that reads one of the pack's targets ([[post]] output) before the
pass that writes it got last frame's picture after a reset; a pack just
made reads it blank. The reset now drops the targets and their bind
groups, made again blank on the next frame; the pipelines stay.

Renderer::reset_shader_pack_history makes the next frame draw as a freshly
loaded pack's first, for either kind. A shaders/ pack's buffers, images,
storage buffers and shadow maps are made again when next drawn, its passes
get their declared uniform values back, and the frame uniforms, custom
uniforms and centre depth forget earlier frames; its programs stay. A
Horizon pack's post history goes black and its eased values, wetness and
frame count restart. Without a pack it does nothing. Nothing calls it yet.

Adds the Nord palette (polar night, snow storm, frost) as a launcher theme with its own dark and light tokens and sky art. Palette themes draw the square Blocks look: no glass, no rounded corners. The night tokens are square everywhere, and the Blocks status dots and controls follow. Blocks and the light glass look draw the baked sky, so resizing no longer rebakes the scene per frame and stays responsive. Settings gains the launcher-theme picker in the Blocks look. Nord now shows the sky instead of the scene's pale halo.
The first install on Windows now checks SHA256SUMS.sig (a Nightly's

looked for on the PATH and in Git for Windows. Without OpenSSL 3 it says
so and keeps the GitHub SHA-256 check.

Horizon took shadowDistance, sunPathRotation, shadowIntervalSize,
shadowNearPlane and shadowFarPlane from a program's vertex shader too, and
read nothing of shadow.fsh but its formats when the pack has no shadow

only in final.vsh, gbuffers_textured.vsh or shadow.vsh (its shadow
projection, shadow camera and sun stayed at the defaults), and applied
shadowDistance and sunPathRotation declared only in shadow.fsh of a pack
whose shadow buffers nothing read.

Review: hurts dealt after the creature tick (ordered TNT, beds and anchors,
falling blocks, conduits) still waited for the next tick. Explosions and
falling blocks now settle right after each hurt, before the push, and the

InfestedMobEffect.onMobHurt) are handled before the teleport, where the
enderman was hurt and from its random's next draws, as
LivingEntity.hurtServer runs them before Enderman.hurtServer teleports.

`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

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
runs a pack's gbuffers_skybasic (render stage SKY, vertex colour fogColor), and
the gl_Vertex values our probe packs read there (render distances 12 and 8) fit
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.
Frame carries the boss bar's world fog; PackSky draws only the fan then, in
the fog colour.

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),

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.

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

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.
New lan_e2e check entity-die: a sneaking host and LAN guest break each
kind 3 blocks from a sculk sensor, which now hears 15.

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.

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 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).
