🤖 Agent: guest_pickups only scans items when one reaches the player's columns; the columns follow the item list's stamp (scan first after any write), so a /tp or explosion mid-pass cannot hide an item. Bench lan_guests -2.4 to -5.7 ms/tick at 134 players.

🤖 Agent: the mesh key snaps to 4-cell steps with the radius grown by 4 cells, so the drawn window still covers the view; inside the cloud layer the sub-cell offset keeps the faces in place, and the new test pins the same world cells across a snap step.
🤖 Agent: pure move of menu clicks out of game.rs (added vs removed lines differ only in the module header, use lines and doc rows); it merges cleanly with the other moves in this series and passed a union build and tests.
🤖 Agent: pure move of the frame's CPU geometry out of game.rs (added vs removed lines differ only in the module header, use lines and doc rows); it merges cleanly with the other moves in this series and passed a union build and tests.
🤖 Agent: pure move of dropped items and orbs out of game.rs (added vs removed lines differ only in the module header, use lines and doc rows); it merges cleanly with the other moves in this series and passed a union build and tests.
🤖 Agent: registered slot_source ids resolve only for execute if/unless items, after literal ranges and inline sources, as SlotSourceArgument tries them; the ignored test writes its world under the cwd, so run it from a scratch dir.
🤖 Agent: pure move of falling block entities out of game.rs (added vs removed lines differ only in the module header, use lines and doc rows); it merges cleanly with the other moves in this series and passed a union build and tests. I merged main: #12992 had rewritten tick_one_falling in game.rs, so falling_blocks.rs now holds main's code, checked verbatim.
🤖 Agent: pure move of the startup resource loader out of game.rs (added vs removed lines differ only in the module header, use lines and doc rows); it merges cleanly with the other moves in this series and passed a union build and tests. I merged main (AGENTS.md row only).
🤖 Agent: pure move of lighting a nether portal out of game.rs (added vs removed lines differ only in the module header, use lines and doc rows); it merges cleanly with the other moves in this series and passed a union build and tests.
🤖 Agent: pure move of a level's block tick phases out of game.rs (added vs removed lines differ only in the module header, use lines and doc rows); it merges cleanly with the other moves in this series and passed a union build and tests.
🤖 Agent: stacked on #13205 (queued first); a filtered modifier now applies only to particles whose source block or item matches, instead of being skipped.
🤖 Agent: /tp ends with setOnGround(true) for any entity not fall-flying (TeleportCommand.performTeleport); the projectile, rocket, trident and falling block impls ignored it, and the corpus now reads OnGround for every kind.
🤖 Agent: checked as a pure move: the added and removed line multisets match except the module header and three rustfmt line joins; no non-test code changes.
🤖 Agent: build timing output now follows the requested target directory instead of the default target/, so --target-dir runs don't write into the checkout.
🤖 Agent: a piston push clears OnGround on boats and minecarts as PistonMovingBlockEntity.moveCollidedEntities' setDeltaMovement path does; green in a union with this wave.

🤖 Agent: the tab list draws whatever rectangles the caller's mark callback returns, with the same 9-pixel column rule; the game passes horizon_cosmetics' MARK for listed Horizon players and the vanilla probe passes none, so tab_list.rs no longer names horizon-cosmetics.
🤖 Agent: the crash path now runs registered hooks (crash::on_report) under an RwLock that ignores poisoning, and entry.rs registers telemetry::keep_crash before anything else in main, so every report still reaches telemetry exactly as before; render loses its telemetry and bench dependencies (47 → 45).

A particle modifier's `filter` (a block or an item, or a list of them) now
limits it to the particles that carry one of them, as BlockParticleOption
and ItemParticleOption do: particles sent from the server (/particle with a
block state), landing and sprinting dust, and item particles now carry
their block's or item's id. Observed on the real mod: a filtered
`minecraft:block` modifier changes /particle's stone particles and not its
dirt ones, and no modifier reaches the crumbs of a broken block, which
vanilla makes without the particle providers (as Horizon does).

A block modifier with "disable_particles": true stops its blocks' own
particles: their Block.animateTick doesn't run, so a torch has no flame
or smoke. Measured on the real mod (Polytone 26.3-6.8.6, a pack with
only that modifier on torches): the torches show neither. Block
modifier emitters run apart from animateTick and are left as they are
(not measured together with disable_particles).
A file that only disables particles is now kept (it used to be dropped
for having no emitters).

biome tags too. Tags are read from the merged packs' data with nested tags,

🤖 Agent: the UUID comes from the mob's own random before LivingEntity's yaw draw, and the spawn yaw keeps the level's random, as Entity.<init> then Mob does; seed_sync cases 8-13 pin it.
🤖 Agent: main moved use_hand into game/use_hand.rs, so I ported the fix there (apply_use_cooldown after a successful useOn, as ItemStack.useOn's applyAfterUseComponentSideEffects) and dropped the one-off docs/parity note and probe.
🤖 Agent: I scaled the kept-tile budget to the view (fit_to_view: KEPT_BYTES times tiles / 4700, the 512-chunk view's count, capped at KEPT_BYTES) so a small view no longer holds the full budget, with a test; merged main.
🤖 Agent: stacked on #13029 (queued first); the override map is rebuilt from the registry on each pack load, so a pack swap drops overrides the new pack no longer has.
🤖 Agent: g.rain is now (rain + thunder) / 2 in both the particle and post expressions, and the fog-end tests pin a few rain/thunder pairs with independent numbers.
🤖 Agent: a layered HDR frame keeps its own targets through the scaled screenshot; only the non-layered path takes and releases them, so the next frame after the shot needs no rebuild.
🤖 Agent: a model quad whose sprite is missing from the atlas is skipped, not drawn with a zero rect, so a pack with a typo shows a gap instead of a stretched texture.

🤖 Agent: the moved constants keep their old public names (horizon_telemetry::DEFAULT_ENDPOINT, horizon_friends' STUN list, etc.) as re-pointers to horizon-addresses, so callers don't change; main merged in with telemetry taking both horizon-addresses and horizon-platform, and all four workspaces' locks are --locked clean.
🤖 Agent: check_file_size.py diffs against the merge base with rename detection, so a file over 3000 lines that is renamed and grows still fails, while big files that shrink or stay the same pass; no pinned list of files.
MeshKey held the camera's own cell, so every cell the camera crossed rebuilt
the cloud window and copied its 148k vertices (6.5 MB) to the GPU in
r_materials: 206 ms of CPU over 17 frames of a 10 s flight, worst frame 28 ms.
Anchor the origin to a 4-cell grid and let Uniform::offset carry the rest of
the shift, widening the window by the grid so the ring the shift uncovers
stays past the cloud fog end, where entity.wgsl's fade already has alpha 0.

TabInputs::horizon (a "plays Horizon" flag drawn with
horizon_cosmetics::mark::MARK inside the renderer) becomes TabInputs::mark,
an extension point returning the rectangles to draw after the head, or
none. The game passes Horizon's mark from horizon-cosmetics; the vanilla
probe and the tests pass none. Same pixels, same column rule.
tab_list.rs no longer names horizon-cosmetics; extras.rs and extras_ui.rs
still do, so render -> cosmetics stays until they move.

A pack's custom particle under a vanilla id (`minecraft:rain` from
assets/minecraft/polytone/custom_particles/rain.json) now replaces that
vanilla particle wherever the game spawns it, drawn from the vanilla
type's sprite set, as the wiki describes. Visual Effects+ turns rain
splashes into ripples on the ground this way; they now show as in the
real mod.

A custom particle type with a `model` is now drawn as that block model's
faces instead of being hidden: elements, faces, `#texture` references,
parents and element rotations are read the vanilla way, the particle's
size scales the model and its rotation mode turns it as it turns a
sprite quad. `none` keeps the model in the world's axes.
Checked against the real mod with an asymmetric test model: `look_at_xyz`
turns the model's +Z to the camera, `none` keeps +X east and +Z south.

A pack's `g.rain` read the rain level alone, so plain rain counted as a
thunderstorm. Measured on the real mod with a sky colormap whose row is
`g.rain`: clear sky reads the colormap's bottom row, rain its middle row
and a thunderstorm its top row, so `g.rain` is (rain + thunder) / 2.
With rain counted as a storm, a pack that picks its sky by `g.rain`
showed its storm sky and fog in plain rain; its rain sky now matches the
real mod's.

🤖 Agent: the portable rule reads the same cargo metadata packages as the layer check; a listed crate that stops being an engine crate fails too, so a rename can't silently drop the rule. Merged main in (#12983 landed); 16 tests and the check pass on the result.
🤖 Agent: each projectile's run is closed with an id-0 run, so geometry drawn after it never inherits its motion; potions with no id yet keep the camera's.
render/telemetry.rs moves, unchanged apart from its GPU source, to
horizon-client-lib (crates/horizon-client/src/telemetry.rs), still at
horizon_client::telemetry. The renderer keeps only engine facts and
extension points:
- gfx::Adapter / gfx::adapter() / gfx::gpu_kind: the adapter as found,
which telemetry's system() reads (was telemetry::set_gpu).
- crash::on_report(hook): runs each report before it is saved; entry.rs
registers telemetry::keep_crash at startup (was a direct call).
horizon-client-render no longer depends on horizon-telemetry or
horizon-bench: two layer exceptions go (47 -> 45).

🤖 Agent: over the ~500-line guideline (+1731/−1519), but it is one screen moving onto the shell plus the shell parts that screen needs, so it lands as is. The collapsed page list lays out from the drawn font, so the clicks match what is shown.
🤖 Agent: mod fluids join minecraft:fluid after vanilla's (source, then flowing) and the content identity, so a client without them is refused. Nothing places them yet.
🤖 Agent: FluidKind becomes a table index with no behaviour change; same_family and is_source compare source rows, and FluidMask stays u8 until mod fluids need more.
🤖 Agent: removed tools/probes, the harness and the doc page: they run only against paper-pumpkin-parity, which lives outside this repo. The 16-line PlayerList.saveAll fix and its 3 Game tests stay (they pass with prepared resources).
🤖 Agent: merged main, keeping both piston_push fns (yours and main's block triggers); pushes only read bodies within 2 blocks of a moving block, which is safe because only the pushed body moves during the pushes.
512 MB is about one 512-chunk view. A shorter far distance now keeps the same

🤖 Agent: check_addresses.py tokenizes Rust (strings, raw strings, comments masked) and strips #[cfg(test)] items, so test URLs and translation keys like mco.info don't count as hosts; allowed in tools/addresses.json can only shrink against --base.
The OS, CPU, memory, drive, power and GPU probes move, unchanged, from
horizon-telemetry/src/system.rs to a new engine crate, horizon-system, with
a `Machine` description. The crash report and the renderer's GPU info read
it directly; the crash report's own copy of `command_output` goes (the
shared one opens no console window on Windows).
The Horizon layer depends on the platform only (docs/layers.md), so
telemetry reaches the probes through a first platform crate,
horizon-platform, that re-exports horizon-system as `system`.
`horizon_telemetry::system` stays as a path for the launcher and the
benchmark; `System::detect_in` copies a `Machine` into the payload.
No new layer exception: render -> telemetry stays until M3 moves the
renderer's telemetry module out.

🤖 Agent: the client placement preview stays client-side: TntBlock.prime and PistonBaseBlock.onPlace act only on the server; new harness client_redstone_preview.
🤖 Agent: merged main after #12899: one load_with_visibility_models_and_defaults takes both the decoded entity-models document and the item defaults, so neither is read twice.
🤖 Agent: merged main (vibration_tests.rs: kept both test tails); trampled farmland and broken turtle eggs now emit their game events where vanilla does.
🤖 Agent: fake-player part only now (the per-tick box cache went to #13051); guests still build the others' current boxes each turn, as main does. Benchmark posted above.
🤖 Agent: tools/check_layers.py only reads cargo metadata (--no-deps --offline), so nothing builds and nothing players run changes; with --base it refuses any new exception in tools/layers.json unless the crate itself is new (a split-out crate keeps its parent's).
tools/probes/item_on_block_cooldown ran only against paper-pumpkin-parity, a

AbstractBoat.checkInWater and isUnderwater add a block's y and its water
height in float, and floatBoat lands a falling boat at the float
getWaterLevelAbove() - getBbHeight(), with waterLevel = getY(1.0). Horizon

FishingHook.onHitBlock calls Projectile.onHitBlock before it rebounds,
so a bobber powers a target block (target_hit, the criterion), rings a
bell struck on its body (bell_ring), chimes amethyst and tilts a big
dripleaf. Horizon's bobber only posted PROJECTILE_LAND.
The bell and target helpers take a ProjectileHitter (owner, guest,
arrow, type, position) that thrown projectiles and the bobber both
build. New harness test_fishing_hook_blocks_parity.py casts onto
target blocks on vanilla's and Horizon's dedicated servers.

Leashable.computeElasticInteraction turns every attachment point with
Vec3.yRot(float), Mth's float cosine and sine of a float angle, and
checkElasticInteractions adds the whole push in one addDeltaMovement:
v + (force * axis + relative * 0.11). Horizon turned a single lead's
points with exact trigonometry (only the quad lead used Vec3.yRot) and
added the push as (v + force * axis) + relative * 0.11, so a pulled
mob's Motion and yaw drifted once it had turned.
Both ends of a single lead now turn with the same Vec3.yRot helper as a
quad lead, and the push is added as one sum. The sum is the line the
quad lead shares, so a quad lead's Motion now follows vanilla's formula
too.

With HDR on the float frame, an F2 taken at a Screenshot Quality above 1

unscaled F2's picture at that size (the world mapped to SDR as
Hdr::sdr_screenshot maps it, the HUD over it by coverage), with its
-hdr.png beside it. Then the large targets are let go, so they don't
stay in video memory, and the window's next frame makes its own again.
HDR off, frames that aren't layered, unscaled screenshots and the
window's own frames are unchanged.

🤖 Agent: the large-PR process says the spec check is run by maintainers' agents; nothing enforces it in CI yet, so reviewers should ask for the 'Spec: #' link on PRs over ~500 lines.
🤖 Agent: tools/parity_gaps.py anchored its badge fallback on the vanilla-parity badge this removes; it now inserts at the end of the badge row, and test_parity_gaps checks that order.
From the 2026-11-08 contributors' stage: game.rs (~21.7k lines) and
gfx.rs (~10k) slow incremental builds. tools/check_file_size.py
compares each added, changed or renamed .rs file with the merge base:
over 3000 lines it may shrink or stay, never grow; a new file over the

not checked. Runs on pull requests (with their base) and in pr_ready.

it; parity work stays on 26.3 (redstone first), newer servers via Via;
AMD FSR may be vendored but NVIDIA-licensed libraries only as an
optional native mod that downloads them; the JVM bridge is a separate
optional download, never on by default. The PR template points large

Ludovic, 2026-11-09: the Horizon layer moves to its own repository
after the split, so it builds against the platform's public API and
never the engine. tools/layers.json now says which layers each layer
may depend on (engine: engine; platform: engine, platform; horizon:
platform, horizon). The launcher's and horizon-server's 7 engine
dependencies join the exceptions (47).

Kept tiles at the seam with the near chunks (`Plan::stands_in`) are dropped

- SummonCommand.createEntity loads a mob summoned without NBT from
{id:..}: yaw 0 and no level-random draw (Horizon drew one, which also
shifted every later level roll).
- EntityType.create snaps a spawn egg's, a dispensed egg's and a mob
bucket's mob to Mth.wrapDegrees(level.random.nextFloat() * 360).
- SpawnEggItem.spawnOffspringFromSpawnEgg snaps the baby to yaw 0.
spawn_mob_internal takes a SpawnYaw (Level, Created, Fixed); other

🤖 Agent: findNearestMapStructure searches ring by ring across every random-spread set, takes each set's first hit per ring and stops at the first ring with a hit.
A datapack's @e[type=marker,tag=...] selectors got quadratically slower
with every other entity in the level: select_in_level ran the tag/score/team
filter on every candidate before the type test, and tags_of finds each
entity by a linear search (about 40% of the server thread with 8,000
falling blocks around).
EntitySelector tests the type first. With type= and no scores= or team=
(whose holders may be made as they are read), the rest of the extra filter
is a pure test of each candidate, so the candidates of another type now
leave before it. The type test moves into selector_types_match, used for
both passes.

push_voice mixed every queued chunk at once, so a speaker's second block
played over its first, and finished chunks were popped from the front of
one shared queue whatever their source. Each (mod, source) pair now has
its own queue: a source plays its head chunk, hands the rest of a buffer
to the next one, and sources play at the same time. Positioned audio
fades linearly to silence at 48 blocks (distance_gain(None, _) was always
1). A source holds two seconds at most, 64 sources play at once, and
nothing is queued without an output device or outside the window's game.

A few thousand falling sand blocks took the server tick to 600-800 ms:
tick_one_falling took each block out of self.falling and put it back, every

A clock of a thousand pistons spent most of each tick on its pushes: every
moving block walked every entity in the level and read its box, and the
collision view looked each piston up by scanning two lists.
- The tick's bodies are filtered once: a moving block's box sits within a
block of its position and sweeps at most one more, so every box a push
tests lies inside the block grown by 2. Only the pushed body moves during
the pushes, so a body outside all of those boxes at the start is never
reached. Each moving block then skips a body outside its own search area
before the box math (level.getEntities in moveCollidedEntities).
- Step heights are read once per tick, not once per moving block.
- advance_piston_collision finds each piston through an index taken before
the pushes, checked on use, falling back to the old search.

Vanilla's Entity makes its UUID from the first two draws of its own random
(Mth.createInsecureUUID), and LivingEntity.<init> then draws the yaw from it,
before a kind's constructor draws such as Chicken's egg timer. Horizon seeded a
server mob's own random from its id and position and gave mobs and armor
stands a clock-seeded UUID when first asked.
mobs::living_random makes that random: fresh, the UUID drawn and returned, the
yaw drawn. Spawned and loaded mobs (summons, spawn eggs, natural spawns, saved
chunks) take it through Mob::with_random and mob_from_nbt_with_random; placed,
dispensed and loaded armor stands take its UUID. A UUID in the tag still wins.
Mob::new keeps its id-seeded random for the client's copies. Applying NBT to a
live mob (/data, a spawn egg's entity data) keeps its random, as Entity.load
fills in the same entity.
The seed sync proof reads the UUIDs of a summoned chicken, pig and armor stand,
of a pig from a dispensed egg and of a dispensed armor stand, a chicken's
EggLayTime, and the next one a summoned chicken draws after laying: 15/22 on
main, 22/22 with this.

`mip_chain` generated the sprite array's mips one layer at a time: at startup
and at every pack load or reload, a few thousand layers at 64 px for a 64x
pack ran on the pack worker alone, while the rest of the reload's decode
stages already spread over `par::par_map`.
Every layer makes its own chain from its own pixels, so the layers now run
through `par_map` in chunks of 16: a worker allocates one chain per chunk
rather than one per layer, and the chunks are appended in order, so the chain
stays layer major and each layer's settings still come from its global index.
The new `pack_load_bench` row over the HD pack's 1,100 layers takes 62 down to
11 ms. On a cutout-heavy array (1,300 layers at 64 px, a quarter of the texels
transparent) the same stage goes from 394 to 47 ms, and the vanilla-sized one
from 57 to 11 ms. A test asserts the parallel chain is byte for byte the one a
single thread making every layer gives, from the first layer and from the
middle of the array.

`decode_components` read the 23 component IDs it models one at a time with
`Tag::get(&str)`: each call encodes the ID to UTF-16 and walks the compound's
`BTreeMap`, whether or not the stack carries it. Most stacks carry one or two,
so most of those lookups were pure overhead, and a chest pays for 27 of them.
`Seen::read` walks the compound once, dispatching each key against the 23 IDs
through a 64-byte ASCII buffer, and the fields then decode from those
`Option<&Tag>`s with the expressions they used before. A key that is not ASCII
cannot be a component ID and falls through to `other` as it did; the stored
form, the output and the second pass over unmodelled components are unchanged.
A one-component stack decodes in 0.36 instead of 0.93 us (2.6x) and an empty

Under HORIZON_HDR_FRAME=float, a 0.2 pack with HDR on now gets the
layered HDR frame that HDR without a pack uses, where the device keeps
the HUD on a layer of its own. Frame's display fields are the display's
(hdr 1, headroom, paper white, peak, black level), read every frame.
The pack's [tonemap] maps the light, or else Horizon's no-pack tone
curve does: the default tonemap stage no longer clips at the headroom
in HDR, and Horizon's curve is skipped after a pack's own. The HUD is
laid over the picture by coverage as without a pack. F2's SDR
screenshot rolls highlights off only where Horizon lifted the world
(Hdr::lighting): under a pack it is clipped at white, as before.
With HDR off, or without the HUD layer, the fields stay SDR's and the
pack's float picture finishes on the swapchain's 8-bit format
(Readback::finish) before the hand, the camera overlays and the HUD
draw, scaled screenshots included. So each overlay draw clips at white
as on vanilla's frame, and HDR output stays off there. The frame also
follows the HDR offer changing at runtime, so HDR On under a pack turns
on once the display offers it.
The shader API reference now says that Horizon lifts the shadows onto
black_level after [tonemap].

Resource packs' Polytone post chains (wiki "Shaders") run their vanilla
post_effect chain over the world while their activation_condition holds,
with a uniform block per expression uniform, the PolyGlobals block (the
world's projection and camera, the sun's angle, the time of day and the
frame's tick delta, the player's position) and the packs' post_targets,
kept between frames, in every chain. Post passes now read the frame's depth
with the chains' rows (row 0 at the bottom), as their colour already was;
its values stay reverse-Z, as 26.3's are.

A GPU particle type's fade (wiki "GPU Particles": the fractions of its life spent
fading in and out) ramped its alpha linearly. Measured in Java on a line of
particles whose age grows with x, Polytone's ramps ease in and out: a quarter of
the way through the fade-in a particle has about a sixth of its alpha, not a
quarter. Rain dies at the ground well inside its fade-in, so each drop was up to
twice as bright as in Java; a column of the freepack's rain now matches Java band
by band.

The float HDR frame's HUD target was in the frame's float format, so a
HUD draw no longer clipped at white before the next one blended over it:
a text highlight added over a light backdrop, then a 50% black panel,
came out at 0.65 instead of vanilla's 0.5. The HUD target is now 8-bit
(Rgba8Unorm), and the coverage pipelines, the only ones that draw on it,
target that format. The composite subtracts the backdrop as the 8-bit
target holds it, so pixels no HUD draw touches stay exactly the world.

A clock of a thousand pistons froze the window: the client rebuilt
World::moving_pistons after every BlockEvent that starts a move and every
block change that ends one, and each rebuild compared every previous entry
with every current one and scanned the pending uploads for every fallback
entry. A pulse sends about three packets per piston, so it cost O(N^3).
Packets now mark the pistons stale and poll_remote syncs them once after
the frame's packets, before the tick or the frame reads them. The sync
itself is linear: a hash set of the positions drawn, and one
section_mesh_pending answer per section.

Resource packs' Polytone config entries (wiki "Polytone Configs") get a page:
the card of a pack with options carries a small sliders button at its right
edge (as Respackopts does), which opens that pack's options in the frame of
Horizon's settings screens. Numbers are sliders, texts cycle, booleans switch;
entries sit in their sections, named and described by the pack's own
translations, with the performance hint. Done keeps what changed in
polytone-configs.json beside options.txt, and the packs load again with it, so
overlays and expressions that read the configs follow.

🤖 Agent: native builds try the instance's commit first and move to the pin only for a pinned mod left out as OtherVersion (made_elsewhere, unit-tested).

A boat's water patch (RenderTypes.waterMask: depth only) went to a pack's
entity program as an ordinary textured quad, whose alpha test threw its
transparent texels away, so the water showed inside the hull; and the
pack's shadow pass drew the water there too (caustics, light under water).
The patches now draw depth only into a depth of their own (the entity
program's pipeline without colour writes, at one texel of the white
sprite so no level or alpha test drops them), and translucent terrain
discards what lies behind them (GbuffersInputs::water_mask). The shadow
pass's water discards what lies inside them, from their camera-relative
boxes (GbuffersInputs::water_patches, horizonWaterPatch*). A hull before
its patch keeps its motion matching (at_velocity).

AllayAi sets ITEM_PICKUP_COOLDOWN_TICKS to 60 when an allay throws an

The allay's Brain writes item_pickup_cooldown_ticks while the cooldown

Black Level has no Auto: 0, the default, is true black, and the saved value

Peak Brightness goes to PQ's 10 000 nits by hand, in the saved value and in

Adds Host::push_voice(samples, sample_rate, at): a mod queues mono samples and
the output callback mixes them with the game's sounds, with distance gain and
direction when the mod says where they were spoken.
The roadmap entry "Proximity voice chat as a native mod" names what is missing
for such a mod: a way to carry voice between players and an audio path in the
game. The carrying side already exists (net_send_to_server, native_net_from_server
on a mod's own channel); this adds the audio side.
- horizon-client-render: VoiceChunk and a queue in Mixer, mixed in mix() before
the limiter; MixerBackend::push_voice caps the queue at two seconds and refuses
a burst rather than delaying it; Audio::push_voice forwards to it.
- horizon-client: Game::native_push_voice, listed in native-hooks.json under
helpers so the generator emits Host::push_voice (API 360), its trait default
and the game's implementation.
- tests: a queued chunk is mixed centred and dropped after it played out; a
position pans it by the listener's right vector (facing south, -X is right).
The audio itself could not be listened to on this machine (headless, no output
device), so the mixing is checked by tests only.
🤖 Agent: unblocks main's verify on both counts: the reviewer set matches .github/trusted-reviewers.txt (itarqos5), and the 1.12.2 upgrade case runs only where the datafix tables are prepared (#12756).
🤖 Agent: the raid banner carries item_name/rarity/tooltip_display on the wire like Raid.getOminousBannerInstance; hide_tooltip=false is omitted as optionalFieldOf does.
🤖 Agent: the first-tick bubble column check moved into tick_with, so the server thread runs it too; pearls keep their creature-tick column hooks, as vanilla does both.
Since #12756 the pre-1.13 upgrade reads datafix-tables.json from the prepared
resources. CI's verify has none, so the test panicked there and on every
checkout nothing was prepared in. It now checks 1.12.2 only with the tables,
1.16.5 always.

Vanilla keeps two fields: LivingEntity.damageCooldownTime, the hurt
cooldown a hit sets (never saved, kept by an in-place /data load), and
Entity.invulnerableTime, saved as invulnerable_time, which counts down in
commonTick and makes the entity invulnerable while above 0. Horizon used
one field for both, so a hurt mob saved its cooldown as invulnerable_time
and a summoned invulnerable_time only acted as a hurt cooldown.
Mob gets invulnerable_time, the only field the key loads into and saves
from. It counts down at the start of the mob's tick and joins the
Invulnerable flag in the damage guard (#bypasses_invulnerability passes).
The cooldown stays transient and is carried across a /data rebuild again.
Conversion copies invulnerable_time, and the skeleton trap's riders and
horses start with 60 of it.

ender_chest and end_portal are EntityBlocks in vanilla 26.3 but Horizon's
BlockEntity::for_block had no handler for them: they fell through to the
container_size() fallback, which returns None for both, so no block entity
was created and /data get block answered "not a block entity".
Add explicit handlers: ender_chest -> Chest with 27 slots (matching
container_size), end_portal -> new EndPortal variant with no data. Register
EndPortal in fits/id/contents/slots/slots_mut so it behaves like the other
zero-slot entities (DaylightDetector, Bell).
Also fix two traps found in review:
- close_ender_chest removed the block entity entirely; it now copies the
items back into self.ender_items and leaves the entity in place, so a
/data get block after opening/closing still reports the entity.
- Containers::view excluded Beehive/Campfire/Brushable from being treated
as containers (so droppers don't insert into them); EndPortal needed the
same exclusion.
End-to-end verified: /setblock ender_chest/end_portal then /data get block
returns the correct id, and accessing the ender chest's container leaves
its block entity intact.

`PalettedContainer::pack` unpacked all 4,096 cells of a section into a
scratch `Vec<u32>` to find its distinct values, then re-packed them. A
section that holds one value (air, stone, anything filled by one block)
saves as one palette entry and no indices, and that is most sections of a
column, so the unpack was most of their save cost: 3.85 us to pack one.
`uniform()` answers from the stored words instead and returns the same
`Packed` at 0.03 us; a list or global palette compares its words with the
repeated pattern of the first cell, so nothing is allocated and a mixed
section pays one scan that stops at the first mismatching word (measured
at no cost). The saved bytes are unchanged: one distinct value was already
`bits: 0` with no data. One saved column goes from 802 to 704 us.

A person at the computer could spoil a screenshot sequence, a
HORIZON_TICK_SCRIPT scenario or a record-replay with a stray key or mouse
move, and an agent's window took their pointer.
- While one of those runs, the window's keyboard, mouse, wheel, cursor and
IME input of origin user, raw mouse motion, mods' raw keys and the
hardware pad don't reach the game and aren't recorded. The run's own
input (the socket, the replay) still plays; closing the window still
works.
- A person clicking into the window or away from it during a run takes
effect when the run ends: a replay's look and clicks depend on the focus
and the grab.
- During a run the pointer grab stays inside the game; when it ends, the
system pointer follows the grab the run left.
- A visible game an agent starts opens without the focus, and its grab
stays internal (as --offscreen's does) until a person clicks into it.

replied only "timed out before the block broke", which doesn't say the
player is now mining with a bare hand. break now includes `held` in its
reply, both on success and on a timeout.

FillCommand.fillBlocks places each block with BlockInput.place, which
loads the tag into the block entity there and counts a block whose tag
changed its block entity even when the state was already in place. A
hollow fill's core is plain air. Horizon placed the state and dropped
the tag, so every block entity /fill made kept its defaults.
Fixes#12814

ChestBlock's menu provider builds a CompoundContainer over both halves, whose
stillValid asks both block entities; breaking either half ends the menu.
Horizon closed the menu only when the clicked half was removed, so the other
half breaking left a shorter menu over the remaining half.
LecternBlock.useItemOn accepts any stack in ItemTags.LECTERN_BOOKS; Horizon
matched the two vanilla item ids directly, so a data pack adding its own book
to the tag could not put it on a lectern.
LecternBlockEntity.getRedstoneSignal adds one only when hasBook(): the stack
carries a written_book_content or writable_book_content component. Horizon
added one for any stack in the Book slot, so a non-book item a command left
in a lectern read 15 at its last page where vanilla reads 14.
BaseContainerBlockEntity.createMenu asks canOpen, whose LockCode takes the
player's main hand or a spectator; a refusal sends the container.isLocked
action bar naming the provider and one chest-locked sound. Horizon kept a
container's lock on disk and checked it for LAN guests, but the integrated
player's open_menu went straight to the loot roll and the menu, so a locked
chest opened for anyone.
The local open funnel now checks every block entity of the provider - both
halves of a double chest - before it opens, with vanilla's message and sound.
Fixes#12801. In a short view (427x240 GUI px: an 854x480 window at GUI
scale 2, or 720p at its automatic scale) Shaders' page list has room for
four of a pack's screens, and the rest were dropped with nothing to say
so. Now, when they don't all fit, they collapse into one `‹ Name ›` row
with pips (`tabs::collapsed`). Left of the name opens the screen before,
right of it the one after; while searching, the nearest ones with
matches. Each part is a `Tab` target, so RB and LB still step through
every screen and back to the pack list. When the screens fit, the list
is unchanged.

`hud_kit::tabs::collapsed` lays a page list out in one row: the selected
name between `‹ ›` arrows, cut to fit, with a pip per page under it. An
arrow with no page that way is dimmed, and when the pips don't fit across
the row they are a window round the selected one. `draw` paints it.

`goto 8 46 82` aimed at the corner of block (8, 82), so with the default
--near 0.6 it reported arrived while the player still stood in block
(8, 81), one block up a staircase. Whole numbers now name the block and
aim at its center (8.5, 82.5); decimals stay exact positions, so callers
passing entity positions are unaffected.

`LivingEntity.getDamageAfterArmorAbsorb` calls `hurtArmor` before it reads
the armor and toughness attributes, so a piece that breaks on a hit takes no
part in the reduction of that same hit. #11696 showed a chestplate at 239 of
240: vanilla saves Health 16.0, Horizon 16.64.
Every source that reaches `hurt_player_from` (mob attacks, projectiles,
`/damage`, fireworks, the wither, pufferfish) and `hurt_player_by` (thorns,
the dragon, lightning, ender pearls, the world border) now takes the
synchronous equipment path that `damages_helmet` already used: it wears the
armor between the hit's selection and its armor read. Explosions, potions and
the library's environmental ticks (`motion.rs`, `landing.rs`, `hunger.rs`)
still queue the wear for the next drain and are left for a follow-up.
The helmet-phase advancement keeps its reported amount, so no hit's
`ENTITY_HURT_PLAYER` value changes. `tests/fixtures/helmet_damage.json` gains
a `mob_attack` hit that breaks a boot beside one that leaves it worn; the
helmet-damage harness compares both against real vanilla.

Mining a coal vein left 20 of 24 coal on the ground: the drops fell into the
pit, out of pickup range, so break replied picked_up {} and the agent had to

inventory_change and the items it could not reach.

HoglinAi.maybeRetaliate broadcasts the attacker to the visible adult
hoglins, and each takes it only when it is not pacified and its current
attack target is not strictly nearer (setAttackTargetIfCloserThanCurrent).
Horizon's hoglin alerted from its hurt-by goal instead: every hoglin in
range without a target got the attacker, overwritten after the tick. A
hoglin hit in the same tick as a neighbour hit its own attacker once,
then took the neighbour's attacker behind the glass and never hit again.
The hoglin's hurt-by goal no longer alerts. hoglin_hurt broadcasts a
retaliation to the sensed visible adult hoglins, and the event applies
the pacified guard and the nearest-target rule. Piglin alerts and the
generic SetTarget are unchanged. With a player on either side the
current target stays, since each mob's player is its own.

Animals and monsters move several blocks between an agent's calls, so goto
to an entities position followed by attack ID kept failing with "out of

the weapon to recharge and repeats, then walks over the drops. It replies with
hits and inventory_change.
interact-entity's help now says it fails when the entity is not under the

Off Linux's virtual screen, the vanilla 26.3 client that VanillaTickScript
drives sits on the person's desktop, and vanilla's MouseHandler took the
person's pointer: the join grabbed and hid it, a mouse move turned the
player, and every screen the script opened warped the pointer to the
window's middle (releaseMouse has no focus check).
- SDL drops the keyboard, text and mouse events once the script is
installed, and releases what was held; the script's lines never went
through them.
- MouseHandler is replaced by one whose grab is the flag alone, so screens
open and close without touching the system pointer.
- The harness opens the window without the focus
(SDL_WINDOW_ACTIVATE_WHEN_SHOWN=0). Window.focused starts true and only
SDL focus events change it, so the window asks SDL for its real focus
while resources load: the join no longer warps the pointer.
- Window.onResize re-grabs whenever the flag is set: SDL drops the window's
resize events (pixel-size events still resize the frame).

🤖 Agent: End gateways now skip entities past the simulation distance, as vanilla's entityInside does from the entity's own tick. Its new test fails on main's end.rs and passes here. One risk to watch: an entity already in a gateway when its chunk stops ticking keeps its traveller state until the chunk ticks again. The 13 End/portal/server harnesses pass on this head.
interact-entity right-clicked whatever look-at left under the crosshair and
replied ok, so shearing a sheep behind a tree or out of reach looked like it
worked. It now fails naming what is in the way (an entity, a block, or nothing
in reach), and its reply adds inventory_change: the items gained or lost, such
as the wool a shear drops into the inventory.

0.2 becomes the only line served at the HDR note's step 5, so the
additions we expect (which pixels are light sources for post, a
full-screen peak, an SDR output's display values) must not break packs.
A pack that builds `PostInput(...)` positionally would stop compiling
when a field is added.
- `horizon-shader check` refuses, for 0.2 packs, a `Compose` of `Frame`,
any stage input (every `StageKind`'s input and `DisplacementInput`) or
the post helpers' `SurfaceData` in the pack's files, found in naga's IR
(function bodies and module constants) and located by span. Reading
fields and passing a received value along are unchanged; `Surface`
stays constructible.
- 0.1 is left unchanged: it is retired at step 5 and its structs won't
grow.
- The 0.2 reference: `[tonemap]` is a pure mapping to the output its
`frame` describes, once per pixel of each output (Horizon may add
outputs such as an SDR screenshot); alpha is coverage only, never
light; `Surface.color` is non-negative unbounded linear light; `Frame`,
the inputs and `SurfaceData` may gain fields. Changelog entry in
docs/api/shaders.md.

A native mod pinned to an older commit moved the whole build there,

- native_mods::build compiles every mod on the base's own commit first.
Only a mod that pins another commit and is left out for not building
there moves the build to the pinned revision, once; a build that
can't move keeps the first one (a MISMATCH still asks Build anyway).
Rebuild on Horizon (on_base) never moves.
- The fit line for such a version says so.
- The instance's Mods tab shows each native mod's standing: in the
last build on the Horizon played, moved to another commit (amber),
left out and why (red), or, before a build, how it should build.

A chest with exploration maps resolves each one through findNearestMapStructure with skip_existing_chunks, whose skip check read the saved chunk's record (a region read and an NBT parse) for every candidate of every search, and allocated a String per candidate for the reference set. The cost grew with every map resolved and every chunk saved: on the official SMP, uses grew from 0.27 s to 1.23 s inside use_block (#10255). The session now keeps each saved chunk's answer, as vanilla's StructureCheck cache does, and the reference set is checked by name without allocating. The reference file's format is unchanged.

The id tables of the 1.13-era data fixers (flat_tables.rs) and BlockStateData
(block_state_data.txt) were copied from vanilla's code into the repo. They now
come from the player's own server jar, like the other prepared resources:
- VanillaDataFixTablesExporter reads the fixers' static tables by reflection
and records BlockStateData's register calls in call order (its register is
prefixed with a recorder in a private copy of the class, java.lang.classfile),
then checks the recorded calls rebuild vanilla's MAP and ID_BY_OLD_NAME.
horizon-prepare runs it as a new step and writes datafix-tables.json;
OUTPUT_VERSION 4, so installs prepare again.
- horizon-world's datafix/tables.rs reads that file once into the same
&'static slices the fixes used (set_resources from the game's --resources,
else HORIZON_RESOURCES, else the checkout's .local); no per-call cost.
- check_public_tree.py rejects the retired paths and any tracked file holding
50+ entries shaped like those tables; gen_flat_tables.py and
gen_block_state_data.py are gone.
The loaded tables dump byte for byte the same as the old compiled-in ones.

While the live particles tick they are out of the engine's list, and what their

A custom particle with render_type additive_translucent takes the fog over its
colour in Java, as vanilla's particle shader gives it. Horizon drew it through the
additive entity pass, which does not, so the freepack's light rays came out bright
yellow where Java's are tinted by the pack's dense fog. Their quads now carry their
own overlay, which the additive pass fogs. Measured in Java on a single light ray

Measured in Java with the freepack's light rays and a still copy of them: a custom
particle drawn movement_aligned has its texture's top against its velocity, so a ray
rising toward the noon sun hangs its glow below the leaves it starts at. Horizon
turned it along the velocity, and the rays shone up through the canopy instead of
down under it. A GPU particle keeps its texture's top along its motion, as measured
with the freepack's rain.

A custom particle with physics and kill_when_still (on by default) was removed on any
tick it did not move, so one that rests on purpose died on its first tick. Measured
in Java with a copy of the freepack's light ray chain (an emitter with physics that
rests beside a leaf and emits every tick of its 20): Java's emitter lives out its
life, Horizon's emitted once or twice, about a fifteenth of the particles. A particle
now goes when a collision stopped it, as a landed one is.

exclusion_radius (wiki "Custom Particle Types") keeps a custom particle from
spawning within that distance of a live one of its type. Horizon read it and spawned
anyway. The freepack's rain splash, which replaces the vanilla one, sets it to 1: its
ripples covered the ground about twice as densely as in Java.

`en_us.json` grew from 308 to 1047 keys in the week before #11826, which
took `es_es` to 918. The keys added after it fell back to English on every
Spanish screen: the whole controller guide (49), Studio's freecam, keyframe,
path, timeline and top bar (48), the new options (8), and 23 flat keys such
as `Upscaling Sharpness`, `Opaque Ice` and the DualSense and Steam keyboard
descriptions.
All 128 are translated now. The file keeps `en_us.json`'s key order, which
it already followed, so the diff is the new lines only; keys, `%s`
specifiers and every existing value are unchanged. `es_ar`, `es_cl`,
`es_ec`, `es_mx`, `es_uy` and `es_ve` read this file, so they gain the text
too.

🤖 Agent: removes IS_IRIS/IRIS_VERSION/IRIS_FEATURE_* as OQ-2 decided; real_packs over BSL, Complementary (both) and Sildur's: no pack loses a program, Complementary now loads terrain and water (9 skipped → 3).
Vanilla's server never reaches Ready when the world's packs have a
predicate that references a predicate no pack defines (the registry
freezes with unbound values) or predicates that reference each other
(loot validation: recursively called). Horizon read the packs' data
lazily after Done and started such a world.
The dedicated start now reads the data store right after the world
loads, and a partial check of the predicate graph (all_of/any_of terms,
inverted term, inline conditions followed) logs vanilla's diagnostics
and ends the start before anything listens, with exit code 0. Other
holder positions, other registries, single player, LAN and /reload are
unchanged.

`lang.rs`'s test checks a bundled file for stale keys, repeated keys, empty
values and changed placeholders, and deliberately not for missing ones: a
language is allowed to lag, and `Language::load` falls back to `en_us`. So
nothing reports the size of the lag, and `fr_fr` missing 510 of 1047 keys is
invisible.
`tools/lang_coverage.py` prints, for the game's `assets/horizon/lang`:
missing, not in the reference, empty, repeated key or wrong indentation,
changed `%s`/`%1$s`/`%.2f`/`%%` placeholders (the same rule as `lang.rs`), and
values identical to English; and for `launcher/lang`: values identical to
English and a `{hole}` a value drops or adds. `--summary` is the line a pull
request pastes, `--json` the same as data, `--show-keys` the keys behind each
count, and `--fail-under` exits 1 so a later CI job can gate it.
It reads files only: no `.local/`, no network, nothing written.

ServerLevel.tick walks its entities with EntityTickList.forEach, over the
list as it was when the pass began: an entity that joins during the pass
(a breeze's wind charge, a skeleton's arrow) first ticks on the next tick.
Horizon ticked the projectiles mob events add in that same tick, so a
mob's shot took a step before anything could meet it where it was fired.
Projectiles whose id is above the pass's start (ticked_entities_through,
as dropped items already use) now wait; a player's or a dispenser's shot,
which joins before the pass, still ticks at once.

EndGatewayBlock.entityInside comes from the entity's own tick
(applyEffectsFromBlocks), and ServerLevel.tick ticks only the entities in
entity-ticking chunks. find_end_gateway_portals swept every item, mob, boat,
cart and pearl in the End through the gateway check, so an item frozen past
the simulation distance could enter a gateway, and each one cost a block
sweep every tick. It now skips them, and handle_end_gateway_portals leaves a
waiting one's state alone and returns at once when nothing is in a gateway
(it built a Vec and a HashSet of every entity in the End each tick).
The tracker's send pass skips the entities with nothing to send (idle, not
moved, no sync asked, leash as sent) that no client starts tracking, without
looking their state up again, and sweeps the states only when one left.
The official SMP's AFK carpet dupers in the End pile up tens of thousands of
such items (31,972 on 2026-11-08). With 16k of them and one player, the

request_samples and dispatch_meshes locked the job queues that the far terrain
threads share, and those threads run behind the render thread
(far_terrain_current). One preempted while holding a lock kept the frame
waiting: on a busy 8-core laptop at render distance 24 with LOD distance 1024,
lod_wanted took up to 216 ms of wall time with no CPU time. Both now try_lock
and, when the queue is busy, send their requests on a later frame.
ItemStack.matches compares the component patch, and on a non-damageable item
minecraft:damage:0 is a real component (its prototype has none). Horizon read
the number into the damage field and forgot its presence, so two books with
and without it merged.
Test: a book carrying minecraft:damage:0 and a plain one, both enchanted with
sharpness, give no grindstone result; two identical zero-damage books still
merge to two.
SmithingTrimRecipe's pattern is a TrimPattern holder: a registry name or an
inline asset_id/description/decal definition. Horizon parsed only the string
form, so an inline pattern became an empty name and the trim wore no pattern.
Test: a smithing_trim recipe whose pattern is the inline coast definition
gives a diamond chestplate whose trim holds that direct pattern.
ResourceOrIdArgument.lootTable decodes an inline table while the command
is parsed. A minecraft:loot_table entry's value is a HolderSet<LootTable>
(HolderSetCodec over RegistryFileCodec), so an id the loot table registry
does not hold fails the decode, and the command never runs. Horizon
accepted any compound and ran the table.
The inline decode now follows the table's pools, entries and composite
children to each such entry's value, and checks one identifier against
the registry's ids (the world's tables, refreshed on /reload), with
vanilla's either messages. A nested inline table passes its error up.
Lists, tags, other fields and other codec errors are not checked.

ItemStack.getMaxStackSize is getOrDefault(MAX_STACK_SIZE, 1), so a
!minecraft:max_stack_size patch caps the stack at one. Horizon fell back to
the item's own size, letting two stone stack into a single slot.
Test: in an inventory menu, a stone with the component removed and another
on the cursor stay at one each after a pick-up; on main they merge to two.
AnvilMenu.createResult first asks EnchantmentHelper.canStoreEnchantments,
which is ItemStack.has of ENCHANTMENTS (stored for a book). A removal patch
leaves no component, so vanilla gives no result, not even a rename. Horizon
assumed every 26.3 item has one and renamed the stack.
Test: a diamond sword with !minecraft:enchantments and an enchanted book
with !minecraft:stored_enchantments both give no result at cost 0; the same
items without the removal rename at cost 1.
🤖 Agent: the hero's Buy and the prices now share one ownership rule (shop::owns), and a Shop picture's cache key changes when its item files arrive, so the bare-player bake no longer sticks.

cells_without_collision, which every moving particle asks before resolving its movement,
read the block of each inner cell of its swept box and looked at each cell around it, so a
particle moving 0.4 blocks a tick cost about eight times a nearly still one (poof, smoke and
firework sparks about 205-225 ns, flames and end rods about 25). It now visits a column and
a section at a time and skips every section whose palette holds nothing that collides and
nothing that reaches out of its cell; where a section does hold such blocks and none reaches
out, only the inner cells are read. The answer is unchanged.
On the stress_particles mix (isolated benchmark, particles/tick_bench.rs) the engine tick goes
from 3.21 to 1.77 ms. The section test compares the new scan with the old per-cell one on 4000
random boxes, as well as with the full resolution.
tick_particles gets lap spans (tp_*), so the game's own trace shows where a particle tick goes.

EnchantmentMenu's cost and list use ItemStack.get(ENCHANTABLE) and
ItemStack.isEnchantable, so a patch changes the value or removes it. Horizon
read the item's default, so a patched sword offered the default list and a
sword with the component removed still offered enchantments.
Test: a diamond sword patched to value 1 offers costs 5/13/30 with clues
unbreaking 1, sharpness 2 and smite 4; removing the component gives no
offers.
ServerRecipeBook.addRecipes sends a ClientboundRecipeBookAddPacket entry
for each display of a recipe, and TransmuteRecipe.display gives one
shapeless display per material count: map cloning, with 1 to 8 maps, has
eight. The server's book entries skipped every recipe with more than one
display and had no transmute writer, so a learnt transmute recipe never
reached a player's book, although its removal did.
The book now writes a transmute recipe's entries, one per material count
with the recipe's own display ids: the input and that many materials, its
result (the result item, or every item of the input's tag with the
materials added to its count) and the crafting table, then the usual
group, category, placement and flags. A recipe it cannot write in full
gets no entry at all. The ghost recipe still uses only a single-display
recipe, as before.

SmithingTrimRecipe.applyTrim reads PROVIDES_TRIM_MATERIAL from the addition

Test: a coast trim with a gold ingot patched to copper gives a diamond
chestplate trimmed copper/coast.
GrindstoneMenu.mergeItems refuses a non-damageable pair when
ItemStack.getMaxStackSize is below 2. Horizon read the item's default, so a
pair of enchanted books patched to max_stack_size 1 merged to a count of two.
Test: two books with max_stack_size 1 and the same enchantment give no
result; unpatched books still merge to a count of two.
AnvilMenu.createResult asks ItemStack.isValidRepairItem, which reads the
REPAIRABLE component of the input stack: a component patch overrides the
item's default list. Horizon read only the default, so a sword patched to
repair with a stick refused it.
Test: a diamond sword patched to max damage 100, damaged 20 and repairable
with a stick takes one stick and gives damage 0 at cost 1.

While the integrated server's owner plays, its attachments live in
`Game::guest_attachments`; `store_owner` (autosave, pause save) stored the
hub guest's empty copy, so `players/data/<singleplayer_uuid>.dat`, the file
the owner loads from, lost them until a clean quit rewrote it. A crash after
an autosave rolled mods' player data back while the inventory stayed
current. `store_owner` now stores the live attachments, as `save_guest`
does on leaving; the map stays their one owner. Fixes#12612.

The client encrypts its shared secret and the server's challenge with
whatever public key the server's Hello carries. RsaPublicKey::from_der
had a minimum modulus size but no maximum, and no limit on the
exponent; an encryption costs the modulus squared times the exponent's
bits, so one oversized key (2 KiB to 4 KiB already takes seconds per
encryption, a full 2 MiB frame years) pinned a core and held the login
on "Encrypting…" with nothing to cancel it. No account is needed:
it happens before encryption, on any server a player joins.
from_der now applies RSAKeyFactory.checkKeyLengths, which vanilla's
KeyFactory runs on the same key: a modulus of at most 16384 bits and,
past 3072 bits, an exponent of at most 64 bits. Within those limits the
worst case is about 0.1 s per encryption. Real keys (2048-bit, e =
65537) are unaffected.

a_bridge_gives_its_slot_back_when_either_end_closes failed on Windows with
"bridges stuck at 1". When the guest leaves, the relay's copy from the guest
shuts the host's socket down, but Windows doesn't wake the read the other
copy already has blocked on it (as in #6183); that read returns once the
host closes, which the test's host never did. The test now reads the end
of the bridge on the host's side and closes it, as a host's pump does. On
other systems it still checks first that the slot comes back without the
host's help.

DragonFireball is an AbstractHurtingProjectile: it moves and accelerates
as every hurting projectile does, saves and loads with its chunk, and on
impact bursts into dragon's breath, except on its own owner, which it
flies through. Horizon kept the dragon's fireballs in a list of their
own, ticked only in the End with its own motion, and loaded a summoned
or saved one as a static entity that never moved.
Every dragon fireball is now a projectile of its own kind in the shared
projectile engine. The dragon's attack makes one owned by the dragon
(its direction normalized as vanilla does); a summoned or loaded one
reads its motion, power and owner; it is saved, selected, tracked and
sent to clients like the other fireballs, with its dragon breath trail.
Its impact keeps the old list's cloud and burst unchanged, and the End
still ticks the breath clouds once. The old list and its tick are gone.

`TemptGoal` finds its player with `TargetingConditions.forNonCombat()`,

With --offscreen the game's first window is created hidden, but
splitscreen showed windows anyway: ending splitscreen called
set_visible(true) and turned the run windowed (options.offscreen =
false, a windowed renderer), Window 1 was shown again once a player
played in it, extra player windows were created visible, and the
compositors presented on every window (which maps a Wayland window
whatever set_visible says).
Split keeps the run's --offscreen: windows are created and set hidden,
nothing is presented, the frame limiter paces the frames, and ending
splitscreen draws offscreen again. Without --offscreen nothing changes.

`NeutralMob.isAngryAtAllPlayers` is the universal-anger rule: with it on,
a still-angry bee targets any valid player even when its persistent anger
target is gone. Horizon's `BeeBecomeAngryTargetGoal` only accepted the
stored target, so a bee whose target was cleared never picked the player
under the rule.
The second tick of a throwable in a column is in the column's water, so its
drag is getWaterDrag's 0.8F rather than the air's 0.99F; the assertion now says
so instead of expecting the air drag.
ToggleTooltips updates the item's minecraft:tooltip_display component:
each false toggle adds the component to hidden_components, each true one
removes it, and a hide_tooltip an earlier function set stays. The loot
engine had no arm, so a datapack table's toggles changed nothing. The item
layer's TooltipDisplay already reads the component from `other`, so only
the loot arm was missing.
SetWrittenBookPagesFunction runs the function's ListOperation over the
pages of the item's minecraft:written_book_content component, keeping the
title and author an earlier function wrote. The loot engine had no arm, so
a datapack table's pages changed nothing. The item layer's
written_book_from_tag already reads the content, so only the loot arm was
missing.
SetCustomDataFunction merges its compound into the item's
minecraft:custom_data component, a nested compound key by key. The loot
engine had no arm, so a datapack table's data changed nothing. The item
layer already reads the component from `other`, so only the loot arm was
missing.
SetLoreFunction runs the function's ListOperation over the item's
minecraft:lore component and writes the lines back. The loot engine had no
arm, so a datapack table's lore changed nothing. The item layer already
reads the component from `other` (the tooltip's lore_texts, the LAN item
sync and /item modify), so only the loot arm was missing.
`native_add_toast(id, icon, title, description, challenge)` (client,

the item icon, the mod's title in the frame label's place (yellow, or pink
with the challenge sound) and the description as the white line, wrapped
and faded in when long. It shares the five slots and the queue with the
advancement, recipe and system toasts. `native_toast_add` hears it first
as kind `mod` with the mod's id, so a cancelled one isn't queued. False on
a server and without a window. Fixes#12590.

`native_player_inventory_changed(player, stacks)` is heard on the server
when the per-tick `InventoryChangeTrigger` check finds a player's
inventory changed, before any criterion is looked at, so it fires whether
or not the tree has `inventory_changed` advancements. `stacks` are the 41
slots in `Inventory` numbering (main 0..36, armour feet to head 36..40,
off hand 40). The player's state is swapped in. It fires for the single
player, LAN guests and a dedicated server's players, never on a client
of a remote server, and once at a player's first check after joining.
With no mods the slots aren't copied. Fixes#12587.

The Windows check only looked at the game's runtime slots, so removing a

ahead, stopped at the running image with os error 5, and left the version

The animate tick, the music and the ambient sounds read the built-in
biomes' files only: in a biome a data pack adds or replaces, the game
showed the built-in biome's particles (or none) and played the built-in
biome's or the dimension's music and ambience, where vanilla reads the
pack's biome (Biome.getAttributes, its visual/ambient_particles,
audio/background_music, audio/music_volume and audio/ambient_sounds).
- BiomeInfo keeps a biome's visual/ambient_particles. The animate tick
uses a pack biome's own list (the tables keep the built-in ones); a
particle type Horizon lacks still draws, so the others keep their place
in the random sequence.
- MusicTables::at and AmbientTables::at read a pack biome's file
(Biomes::pack_file); an attribute it leaves out comes from the
dimension type, as vanilla's attribute layers do, not from the built-in
biome it replaces.

`RunAroundLikeCrazyGoal` asks `isVehicle()`: any player or mob on the
horse makes an untamed one bolt (unless a zombie horse is
`isMobControlled()`). Horizon checked only the controlling player, so a
mob-ridden wild horse stayed calm.
`Mob.canAttack` refuses a ghast for every mob, and
`HurtByTargetGoal.canUse` ends with `canAttack(lastHurtByMob)`. Horizon's
`spares_target` only knew the iron golem's creeper rule, so a ghast's
fireball made a mob take the ghast as its target.
Prism Launcher 11.1.1 keeps its Minecraft component as

SulfurCube.tick checks for power (primeWhenOnPoweredPosition, which

a cube primed on its first tick and blew up a tick early. The pass now

The row dismissed the method as a field write, but set_damage_value is the
documented clamped write and the anvil, grindstone and mob-slot paths call
it.
The row said arriving entities only wait in portals.arrivals. The ticket is
in the tree: Game::place_portal_ticket adds a PORTAL ticket of radius 3 for
300 ticks, server side, on the nether and end arrival paths.
The row skipped the dump as debug only, but HudAtlas::dump_contents is
documented as the method and F3's dump-dynamic-textures shortcut writes
the atlas PNG through it.
The row said Horizon only runs the old track behaviour. It runs both:
redstone_direction is called from move_along_track_new when
minecart_improvements is on, so point the row at it and name the gate.

Iris 1.11.7 leaves no rain or snow in depthtex0, whether rain.depth is
absent, true or false, and whether gbuffers_weather or its fallback draws
them: probe packs of ours, read in final, in our rain scene and in a
snowy_plains patch of it. Horizon wrote their depth unless rain.depth was
false, so a pack's later passes saw the rain columns as near geometry.
The weather passes now test depth without writing it, and rain.depth is
no longer read. The GPU weather test now expects the scene's depth after
rain and snow for every rain.depth value.

The GUI atlas, which the particles draw from, left out every texture over 1024 wide or 512 tall

A render hook, native_world_warp, lets a client mod give the frame a world warp: its
world_warp(pos, section) -> Warped moves (and tints) every terrain vertex, far terrain's tiles
included, and every entity vertex; after a line // [fragments] its world_fragment(f) -> Painted
paints, retextures or cuts every terrain pixel by where the point really is. It reads sixteen
floats, the camera split for precision and the frame's partial tick at group 2.
The stock shaders hold only comment markers where it goes in; gfx/world_warp.rs fills them in
copies, validates them with naga and builds the warp's own pipelines (no back-face culling) the
first time a source is seen. While it draws, nothing is culled by where it was (frustum, caves,
CPU and GPU occlusion, section faces) and the frame keeps to the per-section draws. A frame
without a warp costs nothing more.
Tests: the warped shaders validate with and without a pixel stage and stay inside GL's 15
inter-stage variables, the stock shaders hold none of it, a broken source is refused with
naga's message, the hook keeps the last mod's warp. Example world_warp_check draws it through
the real renderer offscreen (and --bench times a frame with and without one).

test_mob_ai_parity.py --writers runs the oracle under a JFR method trace of
the traced fields' setters (JDK 25) and marks where each tick starts, so
each divergence knows which vanilla methods set the field that tick. blame
lists first those that set it at the divergent tick and not at the one
before, then the others that set it that tick, then the static candidates.
When the motion differs the position isn't blamed separately: it follows.
With FloatGoal users not marked as floaters again (#542), the pig's first
divergence (tick 2, v) now lists LivingEntity.jumpInLiquid and
Mob.jumpInLiquid -> jump_in_liquid first and second; the static order put
jump_in_liquid sixth.
A level change sends ClientboundRespawnPacket with KEEP_ALL_DATA, so the client's new player
keeps the old one's synched shared flags (on fire, invisible, crouching...). The hub forgot what
it had sent, so a flag that cleared after the change never reached the client: a creative player
who left lava through a dimension change kept the fire on its screen until the next time the
flags changed. The flags sent now survive the change, and ServerEntity.sendDirtyEntityData's
update reaches the player as in vanilla.

ThrowableProjectile.tick starts with handleFirstTickBubbleColumn: every bubble
column block in the box, entered precisely, pushes the projectile before its
gravity and inertia, so the push takes the tick's drag with it.
Horizon had that scan only in Projectile::tick_remote, the client tick of a
server's projectile, so a snowball or an egg thrown into a bubble column rose
for a guest and sank for the host, whose creature tick never ran it for them
(it pushes pearls through their own onAbove/onInsideBubbleColumn pass, which is
a different vanilla call and does not cover the first tick).
The scan is now Projectile::first_tick_bubble_column, run by the shared tick
before its gravity and inertia, so tick and tick_remote both get it once; the
swept columns applyEffectsFromBlocks pushes stay where they were.
LivingEntity.travelInWater sets the vertical movement to 0.2 when
horizontalCollision && onClimbable(). Horizon checked the spider flag
instead, so a mob in waterlogged scaffolding or on a waterlogged ladder
never climbed, and a spider got the climb even when it was not climbing
(Spider.onClimbable is its climbing flag, which on_climbable returns).

LivingEntity.isPushable reads onClimbable live from the block the mob
stands in. Horizon's cached flag was only refreshed by the mob's own push

other mobs pushed it out of a ladder or scaffolding. It is refreshed from
where each mob stands before the tick's snapshot.

Entity.move refreshes the supporting block (setOnGroundWithMovement's

the column under the mob's centre: a pig resting on stone with its
centre over honey took honey's fifth of the fall. The support is now

BlazeAttackGoal fires with levelEvent(1018) at the blaze's block, unless it
is silent: the client plays the shot at volume 2 with its own pitch. Horizon
played the sound itself, at volume 1, drawing its pitch from the blaze's
random, which put every later draw of its AI out of step.
Blaze.aiStep multiplies a falling blaze's motion by 0.6 before
super.aiStep(), so before travel adds this tick's gravity. Horizon did it at
the end of the AI step and slowed the new gravity too: a blaze fell at
-0.04704 instead of -0.0784 on its first tick.

Custom particles take their `colormap` (the vanilla grass, foliage, dry
foliage and water colours, or a pack's colormap) multiplied into their
colour, sampled every tick, per block or once as its `cache` says. Block and
fluid modifiers' colormaps tint the blocks and water they target in the
chunk mesh, keeping the block's own tint where the colormap's pixel is
transparent. Colormaps read the named samplers (`biome_id` with its mapper,
in pixel columns, `temperature`, `downfall`, `y_level`, `day_time`), so
packs' sky and fog colormaps that pick a column per biome load too.
Particle and block sound emitters play their sound events.

Resource packs' GPU particles (`"type": "gpu"`) are spawn records whose
position, size, colour and frame are a function of the time: gravity and
friction as drag, fade, sway, spin, colour and size toward their ends,
texture strips, `area` spreading one spawn over many quads, and quads under
the open sky only with `kill_below_heightmap`. Custom and GPU particles turn
as their `rotation_mode` says (facing the camera, around Y, flat, along their
motion), and `additive_translucent` ones go to the frame's additive pass.

🤖 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.
Controller Settings' binding rows take the player's resolved `Glyphs`

main's HUD kit guide and gains the settings shell as its own section and

🤖 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
wgpu's indirect multi-draw is ExecuteIndirect on DX12, and on Qualcomm's Adreno
each per-section entry costs the GPU more than the flat path's compute copy and

four perf_bench scenes held still, three alternating rounds: 3-11% higher FPS at
render distance 12, 2-13% at 32, the same picture.
ArmorStand.brokenByAnything calls dropAllDeathLoot before it pops the
equipment: a stand that is not small (isBaby is isSmall) rolls its
type's table minecraft:entities/armor_stand when mob_drops is on. Horizon
only popped the equipment, so a data pack's loot for armor stands never
dropped when a stand burnt out, was blown up or broken by /damage. The
break now rolls that table first, with seed 0 (the table's random
sequence, else the level's random), and spawns each stack at the stand.

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.

Blaze.aiStep plays the burn sound and makes two large smoke particles only
in its isClientSide() branch; the window's game already makes them
(ambient::client_ai_step). The server's copy drew 13 more numbers from the
blaze's random every tick (a nextInt(24) and six nextDoubles), so every
later draw of its AI came out different, and a client following a server
heard the burn twice.
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.

When a new chunk generates next to a chunk an older version saved,
BlendingData.getOrUpdateBlendingData calculates the old chunk's border
heights into its own BlendingData, and BlendingData.pack saves them with
the chunk. Horizon calculated them into SavedOldWorld's cache only; the
save kept the old chunk's blending_data as it was loaded, so the heights
were lost.
The Overworld folder now takes the calculated data of a chunk from that
cache when its save is requested, without calculating anything, and keeps
it with the queued record. The encoder replaces blending_data with
BlendingData.pack only when the loaded record has blending_data with the
same section range. The lookup reaches the cache through a weak link, as
the old world holds the folder. Other folders, new chunks and chunks no
calculation reached save as before.

The row skipped the account check as a service. AccountStatus::allows_multiplayer

The row skipped the predicate, but save::dimension_is_vanilla_like is

A portal ticket's streaming area had radius ENTITY_TICKING - level (1 for
the level-30 ticket), so chunks finished only out to ring 2 and a ring-2
chunk never had all its neighbours: its scheduled block and fluid ticks and
block events never ran. Vanilla keeps ring 3 FULL (level 33), so ring 2
(BLOCK_TICKING) runs them. The area's radius is now BLOCK_TICKING - level.

`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.
A tick-by-tick parity trace says where a run first differs from vanilla, not
which code computed the value. `blame ENTITY FIELD...` lists the vanilla
methods an entity's tick runs (overrides resolved, plus the goals its
registerGoals builds) that write the field, directly (putfield) or through
its setter, its own class first, each with its Rust port and the ledger's
gaps on it. test_mob_ai_parity.py prints these under each mob's first
divergence when a ledger has been built, and the port of the vanilla frame
of the first random draw when a draw differs.
A vanilla method that adds `0.3F` to a double works with 0.30000001192092896
(javac folds the widened float into the bytecode); a port that writes 0.3
computes another number. The new `float` gap kind finds a method's widened
float constants in the jar and flags its port (or the fn whose inline comment
names it) when the port, or a fn it calls, spells the value only as a double:
not as `x_f32`, `f64::from(x_f32)`, an f32 const, or the widened value
written out.
🤖 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.
The client kept only the display id of each entry of a
ClientboundRecipeBookAddPacket and looked it up in the numbering of its
own recipes. A server that numbers its recipes differently (a plugin's
recipes, a datapack, another load order) had its recipes dropped, or
shown as another recipe, such as TNT missing on a Paper server.
Vanilla's ClientRecipeBook stores the RecipeDisplayEntry it is sent. The
book now takes each entry as it came: its display, result, category,
group and the ingredients the craftable filter checks. The book's own
entry stays when it is the same recipe (same result, category, layout
and ingredients), so a server of the client's own recipes shows what it
did before, and the entries taken join the groups of the ones kept. An
entry this book cannot show removes the recipe that had its number; an
entry of a category the client does not know changes nothing.

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.

Controller Settings now describes its pages and rows as a settings_shell
Screen, and the shell draws and drives it, as it does Extras and Graphics.
controller_ui loses its own drawing, scrolling, focus, search, click and
Undo code; Undo is the shell's, comparing the whole PadSettings as before
(Screen::differs).
The shell gains Value::Binding: a row that binds a key or a controller
button. The shell starts the wait (Output::Bind), marks the row while the
host waits, draws the button's glyph art, writes the strip and draws the
row's reset (Reset::{None, Default, Changed}). Extras' sort key and
Graphics' HDR shortcut use it in place of Value::Key and Output::BindKey.
Value::Read is a value the focus reaches and nothing presses.
What players get that is new: the search gives the keys back once the
pad moves the focus off it, no stale ring on the page list after RB or
LB, glyph art in binding rows, a "Not bound" note in the strip, Left and
Right stepping choices, rows scrolled into view when focused, and the
same look and focus as Extras and Graphics. Part of #11487.

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

stores (markers, displays, interactions). An armor stand's own death is
a living source no warden can target.
A blast's kill of a painting, item frame, cushion or armor stand is
credited to its causing entity (BlockAttachedEntity.kill /
ArmorStand.kill with DamageSource.getEntity): the mob, the player who
lit the TNT or broke the crystal.

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.

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.
🤖 Agent: item_defaults::shared is the cached item_defaults::read, so the enchantment properties read the same snapshot Items already decoded; the standalone loader still reads its own.
Game::hud_room gathers the boss bars the HUD shows each frame; hud empties the room every

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.

ArmorStand.hurtServer returns false for an explosion, fire that ignites
armor stands and burning, after it has acted on the stand: a blast breaks
it (its equipment pops, then it is killed), in_fire lights a stand that
is not burning for 5 seconds, and on_fire burns 4 health off one with
more than 0.5. The command route had no armor stand arm, so /damage left
the stand as it was. It now runs those sources with the stand's guards
and still fails as vanilla's command does.

- BoxReach (the boats' and carts' mob pre-filter) is worked out from each
mob's real box, so a shulker whose open lid grows its box sideways or
below its position is still found: a boat runs into the lid and picks
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
(Shulker.startRiding).
- The stand's box uses the float height 1.975F, canStayAt the shulker's
scale.
- The harness adds wall, ceiling and squeezed lids, with the stand joined
after and before its shulker, and the boat that runs into an open lid.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Shulker.onPeekAmountChange moves every entity with physics in the lid's
path with Entity.move(MoverType.SHULKER), armor stands included, and
Shulker.makeBoundingBox grows the shell's box by the lid's physical peek.
Horizon pushed only the player and mobs and sized the box from the
dimensions, so a stand resting on a normal shulker sank into it the first
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.

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

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.

As 26.3 wrote crimson and warped forest vegetation: a simple block on nylium,
tried spread_width² times at a trapezoid offset, where there is air. Terralith's

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
an older base without the flag, so every command_exec run (and every
harness that drives it) stopped at

🤖 Agent: A cat or parrot panics from any #panic_causes damage and only a wolf keeps #panic_environmental_causes, as TamableAnimalPanicGoal is built per species; the old fire_ticks gate is gone. I made its test return early without extracted mob data (CI compared None with Some(true)).
🤖 Agent: Primed TNT's box is 0.98F and its eye height 0.15F, widened from float as EntityType.TNT's sized() gives them; the command_exec case reads them back. Merged main (command_exec corpus group order).
Seventeen harnesses need --work-dir (a fresh capture folder) and
--reference-dir, or assert that their fixed capture folder is new.
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.

VibrationInfo keeps the UUIDs of its source entity and of a projectile's

🤖 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

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

A Nintendo pad going by its letters reads its A as the part that
confirms and jumps, but only the binds list and the on-screen keyboard
showed that A. Each caller had to apply the letters itself, and the
guide, declared buttons and notices didn't.
Letter mode is now part of the resolved glyph style:
GlyphStyle::NintendoLetters, which only PadSettings::glyph_style
produces. It is never saved or offered. GlyphStyle::on_pad turns a part
into the button that plays it, the same way input is read.
Glyphs are asked for by what the button does. GlyphOf::Bound(action)
follows the player's binding and GlyphOf::Menu(MenuJob) the fixed menu
map. pad_glyph::Glyph is built only from those, and draw, width, rect,
art, label and color take only a Glyph, so no code outside pad_glyph
can turn a bare button into art or text. Splitscreen's join and
lost-controller prompts stay by position through Glyph::unheld, and a
test keeps that the only exception.
horizon-ctl `pad family FAMILY` and `pad connection connected FAMILY`
let the e2e harness pose as a Nintendo pad. docs/ui-kit.md starts the
UI kit guide with the glyph chain.

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

with jmath::round_f32, and the test expectations are the values the real
26.3 MenuTooltipPositioner returns for the same inputs.

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.

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.

`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.

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.

With Improved Transparency on, the float frame's default lane no longer

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

Vanilla's TestCommand.trackAndStartRunner adds a TestBatchSummaryDisplayer

world_test_def_lifecycle 6 of its 10 differing records, as #11992 noted).

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.

`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.

is the 0.9-high top, so the snow only makes the TNT stuck once a step
reaches that top. A TNT passing 2.5 just above the snow used to be made
stuck early, lose its fall and sink through.

Block loot's `match_tool` (horizon-items) and the loot engine's
ItemPredicate (`item_matches`: `filtered`, entity `equipment`) ignored
`predicates."minecraft:custom_data"`, so any stack passed. They now test
it as `CustomDataPredicate` does (NbtPredicate.matches ->
CustomData.matchedBy -> NbtUtils.compareNbt(pattern, data, true)): a typed
NBT subset, lists matched element by element, absent custom data read as
`{}`, the pattern SNBT or a JSON object converted as DataFixerUpper does.
`compare_nbt` moves down to horizon-world (re-exported from nbt_path) so
the loot engine can use it, and a killer's equipment keeps its custom data
for entity loot predicates.
New harness loot_custom_data: a data pack's dirt table with a pool per
pattern behind match_tool, `loot give @s mine` with sticks carrying
different custom data, 66/66 records equal to vanilla. The loot engine's
`filtered` path gets the same vanilla matrix as a horizon-world test.

The give branch of cmd_loot skipped every target but the player in
place, so the console's /loot give reached nobody on a dedicated

(LootCommand.playerGive gives to every target ServerPlayer).

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
shows the chest beside it); a tab per neighbour is a menu button that
changes what the mod links for that player.

position_riders gave every mob rider of a mob its vehicle's body yaw each
tick. 26.3 does so only in AbstractHorse.positionRider and
Chicken.positionRider, and in AbstractSkeleton.rideTick and Drowned.rideTick

The items loot engine, which /loot rolls with, skipped both functions:

applies the patch as ItemStack.applyComponents does and reads the

it a potion. The feedback names each drop by getDisplayName.

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.

- 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.

`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

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.

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.

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

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

break blocks as its player without injecting into the private

(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.

🤖 Agent: queued. Command reads keep the real bell block entity (and copper golem statue) instead of a synthesized one, so `data get block` matches vanilla's NBT; main merged in.
🤖 Agent: queued. A jukebox without a song now saves no `ticks_since_song_started`, as `JukeboxSongPlayer` writes it only while playing; main merged in.
A content mod's menu type may declare `"crafting": {"grid", "size",
"result"}`: those slots run vanilla's CraftingMenu logic on the menu
engine (live result, consumption and remainders on take, shift-click
crafting, recipe placement), over a grid the block entity keeps. The
result is the menu's own: the block entity never holds it, so hoppers,
comparators and a broken block can't dupe it, and the hub shows guests
the result the game made, again each tick the grid changed.

🤖 Agent: queued. One cost: the stepped tracker paths add a Vec per tracked entity on the tracker tick; small, but it is the hot path, worth a look if MSPT moves.
🤖 Agent: queued. Batch of server click answers; each case matches `Mob.interact`/`InteractionResult` and is in the batch's harnesses, which run in parity.
🤖 Agent: queued. LT + A crafting a recipe repeatedly is new controller input; servers see the same clicks a mouse would send, so nothing server-side changes.
A test-only Java agent makes vanilla's RandomSupport.generateUniqueSeed step a
uniquifier of the calling thread's own, without the clock; HORIZON_TEST_SEEDS=1
does the same in Horizon's unique_seed. A command script's sync_randoms step sets
that uniquifier, the entity-id counter and the level's random in both engines,
and the "seed sync proof" group compares a drop's position, primed TNT's kick, a
dispensed item and the resting phase of four items exactly. The oracle cache
counts the agent jar as an input.

🤖 Agent: queued. Bold is drawn as the shifted second pass and italic as the skew vanilla's `BakedGlyph` uses, and after the #11863 merge styled glyphs keep the HDR emission tier; the 102 sign cases pass.
🤖 Agent: queued. The Nautilus cooldown memory now exists only while it counts down and is erased at 0, as `Brain.setMemoryWithExpiry` does; its harness runs in parity.
🤖 Agent: queued. A one-block predicate now saves as the bare id and partial `custom_data` keeps only the keys given, which is how `BlockPredicate`'s codec writes them; the residual corpus documents what is left.
🤖 Agent: queued. A sideways push leaves `onGround` false, as `PistonMovingBlockEntity.moveCollidedEntities` only sets it for upward pushes; main merged in since my review, no other change.
🤖 Agent: queued. First of the 12086 → 12087 → 12088 series (each includes the one before): new worlds get the game folder's `new-world-datapacks`, copied at creation only.
🤖 Agent: queued. Ending the tick on the first level skips the dimension swap that did nothing, and the ray chunk cache is per raycast, so no stale chunk outlives one ray.
🤖 Agent: queued. One cost to know: the registry-wide cache has 8192 slots that are never reclaimed; past that it falls back to decoding, so it only stops helping, it doesn't grow.
🤖 Agent: queued. The SWAR check tests 8 palette indices per word and has an exhaustive test against the scalar loop, so a bad index is still caught at the same position.
🤖 Agent: queued. The trident attack continues while `alive && (holding a trident || !nav.done)`, which is vanilla's condition rewritten; a drowned that drops its trident now switches to melee.
🤖 Agent: queued. Tools only: one `git cat-file --batch-check` for the heads instead of a process per PR, and the diffs fetched in parallel; same notes out.
🤖 Agent: queued. `TradeWithPlayerGoal.canUse` also stops on hurt and on distance > 16; it reads `cx.w.player` like the existing LookAtTradingPlayer goal does, so guests on a server share that approximation.
🤖 Agent: queued. A ridden cube mob now skips its jump-move as vanilla's `SlimeMoveControl` does while it is a passenger, so a slime on a boat no longer hops off its seat.
🤖 Agent: queued. Matches `ClientPacketListener.handleMovePlayer`: a passenger keeps its seat when the server's position packet comes, instead of snapping out of the vehicle for a tick.
move_pushed applied the resolved movement to position only, leaving the
entity's velocity untouched. In a ticking chunk the entity's own tick
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.

Every session sampled each far tile again (LodSampler::grid): the noise,
biomes and surface rules for 16x16 columns. lod::cache keeps the chunks
generated for detail, but not these samples. lod::bake keeps them in the
dimension's horizon_lod/ folder (append-only bucket files, a record per
tile, zlib), so a reopened world reads them back instead.
- Saved chunks still win over baked samples (SavedLodSampler applies them
on top as before), so edits show as they did.
- A fingerprint guards the folder: lod::cache's build key (version,
commit or executable time, block states, biomes), the level's height
range and the world's data packs (path, size and time of each file).
When it changes the folder is emptied and baking starts again.
- Reduced far detail's approximate samples are kept apart from full ones.
- A record cut short (a crash mid-write) ends its file there; failed
samples (all-empty columns) are never kept.
Measured with a far-grid bench on a world with its data packs (9 tiles
a level, one sampling thread, 16x16 columns a tile; the baked tiles read
back identical):
| world, detail | sample (ms/tile) | write | read after reopening | disk/tile |
|-------------------|------------------|-------|----------------------|-----------|
| To The Max, full | 7.6 / 42 / 48 / 52 | 0.06-0.11 ms | 0.05-0.07 ms | 4-11 KB |
| To The Max, reduced | 4.8 / 13 / 13 / 23 | 0.05-0.08 ms | 0.04-0.05 ms | 2-8 KB |
| vanilla, full (horizon-world lod_grid_bench) | 2.0 / 8.5 / 9.5 / 8.6 | | | |
(levels 0 / 2 / 4 / 6: 16 to 1024 blocks a tile). Writing adds under
1.5% to a tile's first sampling.

Per-call costs in decoration, ported from the To The Max fork onto main
(main's own ore-sphere walk, FxHash tick sets and HashMap are kept):
- Biome filter: each biome's feature list is a bitset, not a BTreeSet.
- matching_block_tag: the decoration world keeps the last tag's states
(environment scans ask one tag up to 32 times per position).
- Block ticks: the region keeps the last 16 default states it resolved
instead of going through the registry's name map each time.
- Lakes: the spot divisions once per axis coordinate, not per cell; the
16x16x8 grid as a byte per column, edges tested a column at a time.
- Ores: a bound per region chunk on OCEAN_FLOOR_WG (its heightmap maximum
on first use, raised by the world's own writes, the only writes that
move it) answers "no column" without reading up to 121 entries; the
blob's sin/cos only once a column is found. Target rules that draw
nothing (all of vanilla's) are memoized per (state, Y ranges held).
- Speleothem Column.scan reads each block once.
Identical output: chunkgen_bench snapshots (32x32, seed 0) and the To The
Max world checksums are unchanged. Interleaved pairs, 4 threads, built

Decoding a template pool loaded every element's template at once
(gunzip, NBT, palette), where vanilla's pool elements call
StructureTemplateManager.getOrCreate only when the assembler first
touches them. In To The Max's bench area the abandoned camp's pools
loaded 180 templates and its assembly used 18 (villages: 32 loaded, 5
used), holding the start chunk while neighbouring threads waited on it.
Pool elements now hold a LazyTemplate (the id and the shared template
store) that loads through the same cache on first use, so templates stay
comparable by pointer. Data packs' template files still win over the
prepared ones (the store keeps them). When two threads load one file at
once, both get the first copy kept (before, the second insert replaced
the first). Its Debug prints the template as before, so the
structure-start checksum is unchanged.

A data pack whose climate reads the interpolated terrain density (To The
Max's ridges are a spline of it) samples that density's input on its 4x4x4
cell lattice in the biome stage. The noise fill then samples the same cells
again for its interpolation. Interpolated samplers now carry their
compiled function's identity. The biome stage keeps the lattice samples
they produce (a 1024-chunk cache beside the biome cache), and the noise
fill reads its corners from its own chunk's and its +X/+Z neighbours'
samples, sampling only the cells none of them holds (the top layer).
This applies only when every sampler under the interpolated input is
pointwise (a new DensitySampler::pointwise_inputs: each value depends on its
own position only, never on the volume's extent or world fields), so the
values are the ones sampling the whole volume gives. Vanilla's climate
doesn't read the interpolated density, so its worldgen is unchanged.
Measured on this branch's base, 35f3dad20, laptop (Ryzen 5 7640U, 4
threads, fast profile), runs interleaved:
- To The Max (seed 0, 16x16 chunks, world_chunkgen_bench): 150.5 -> 162.6
finished chunks/s (+8%); noise 6.55 -> 4.30 ms a chunk. Terrain,
decoration and structure-start checksums unchanged.
- Vanilla (chunkgen_bench, 32x32, seed 0): 5.05 -> 5.10 ms CPU a chunk
(noise); terrain and decorated snapshots byte-identical.

🤖 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.

in the game layer (settle_hurt_teleports: /damage, explosions, projectile

move_pushed applied the resolved movement to position only, leaving the
entity's velocity untouched. In a ticking chunk the entity's own tick
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

The CurseForge app, and mods such as Sodium, create `shaderpacks/` in an instance

itself as one "shader pack, conversion pending" file and listed it under "not yet",

shaderpacks/ only when it holds something, and a zip only when it has a file
under its shaderpacks/ (a bare directory entry no longer counts).

Mannequin extends Avatar extends LivingEntity; it is not a Mob.
Mannequin.addAdditionalSaveData always writes profile, hidden_layers,
main_hand and pose after LivingEntity's fields, and none of
Mob.addAdditionalSaveData's. Horizon left out the four unless they were
loaded, and wrote PersistenceRequired, CanPickUpLoot, LeftHanded and NoAI.
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

EntityDataAccessor.setData loads the edited compound into the same entity,
and Interaction.readAdditionalSaveData reads its width, height, response
and the attack and interaction records. Horizon kept an interaction only
as a generic entity with its loaded compound, and its live data write
took markers alone, so every /data edit answered "Nothing changed".
A server interaction now holds its settings (InteractionState: width,
height, response and the two PlayerAction records) next to its position.
It reads them when it loads or is summoned, saves from them
(addAdditionalSaveData, a record only when set), and a /data edit decodes
the edited compound into the same entity, which keeps its id and UUID.
Every other kind is unchanged.

NeoForge lets mods add item rarities (Immersive Engineering's masterwork) and some blocks carry a
map colour id past 26.3's 61 (Mekanism's gas blocks: 63). The game refuses the whole content

ItemEntity.tick applies gravity (or the fluid movement) first and then
moveTowardsClosestSpace, whose 0.75 scales the already-fallen vertical

after gravity; the native block-contact pipeline is unchanged.

wgpu caps a dispatch at 65535 work groups per dimension and panics past it;
GLSL packs may ask for more (131072). A larger workGroups now runs as the
same number of groups in a shape within the limit, and main works out each
group's place in the declared dispatch, so gl_WorkGroupID,
gl_GlobalInvocationID and gl_NumWorkGroups read what they would there. The
shape uses every group exactly, so no group leaves before a barrier. A
count no shape holds skips the program with a note; an oversized
workGroupsRender dispatch is not run instead of panicking.

naga's GLSL frontend turns a uint/int that an atomic*() call touches into
an atomic type after parsing. A load or store of a whole struct or array
holding such a member then had the upgraded type: `Cell c = buf.cells[i];`
and `uint copy[4] = shared_counts;` failed validation. A whole struct or
fixed-size array of integers in a buffer or shared memory is now loaded
and stored member by member, so each copy keeps its declared type.

The render crate read a trail duration of -1 as the pre-1.21.4 marker, and

A content mod jar whose data files are mostly in the folders 1.21
renamed (recipes/, loot_tables/, structures/, advancements/,
predicates/, item_modifiers/, functions/ and tags/blocks, items,
entity_types, fluids, game_events, functions) was refused by `carry`.
Now the carry moves each such file to the singular name 26.3 reads.
A file the jar also ships under the new name keeps that copy, and a
1.21 jar's stale plural folder is left as it was.
The JSON stays 1.20's: a recipe whose result names its item as `item`
(before 1.20.5), which 26.3 skips, is kept as it is instead of counted
as upgraded, and NBT in loot functions, ingredients and predicates is
not upgraded yet. The report therefore marks such a mod partial

jars until the JSON steps of #10262 land.

LootCommand.dropKillLoot takes the command source's entity as the killer:
a player is the last damage player, so killed_by_player holds, and its

held stack.
For a connected player as the source, /loot kill now reads that player's

LivingEntity.hurtServer compares a hit inside the hurt cooldown
(invulnerableTime > 10) with lastHurt by its incoming amount, before
armor and Resistance, and keeps that amount as lastHurt. actuallyHurt then
reduces only the difference. Horizon reduced the hit first, then compared
and stored the reduced amount. Under full Resistance every hit reduced to 0,
so a stronger hit inside the cooldown was refused. With armor, a second
hit dealt reduced(8) - reduced(4), not reduced(8 - 4).
The comparison now uses the amount after the helmet, freeze and infinity
changes. The existing armor, Resistance, protection, witch and wolf armor
steps get the accepted difference, and last_hurt keeps the incoming amount.

The component parser translated a missing key's fallback as if it were another key, so a fallback that named a
real key showed that key's translation. It now builds the text through Text::translate_with_fallback, as

Every spawn start measured its distance to every player to keep those

them, and the nearest one is the same in any order. The spawn draws are

🤖 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.

TestCommand.showPos takes the source player (getPlayerOrException) and
that player's own pick: its eyes and view, not the execute position. So
`execute as <connected player> run test pos` from another player answers

only accepted the player in place, so the command did nothing.
For a connected player as the source, /test pos now picks the block with
that player in place (for_player) and only the pick runs there; the test
is looked up in the command's level and the issuer told afterwards. Every
other source keeps its current rule, and the highlight packet is

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

lengths don't imply equal boundaries: `İ` (U+0130) grows from 2 bytes to 3

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

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 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

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

🤖 Agent: stamps the existing chunk_tickets fragments (API 412/413, NATIVE_HOOKS_API 413); tests.test_stamp_native_hooks 10 OK, verify green, and this exact head built into the SMP engine on playhorizon (rtp2), whose /rtp proof passes with no slow tick. The SMP 0.35.1 PR in horizon-mods needs it.
Decoration scheduling measured, sorted and ranked every proto chunk each update.
Ranks are unique, so only chunks without one need their distance; the rest
pop from a heap until the workers are busy. A server with 200 players spread
over the map held ~57,000 protos and spent a fifth of its tick here.
The heap pops in the order the full sort gave; unranked chunks at the same
distance now go by position instead of where the unstable sort left them.

`instance others --folder` and `copy-from --folder` now accept a folder whose
children are CurseForge instances, the `Instances` folder the app shows the
player, as well as the modding folder above it. Before, that folder found
nothing.
When nothing is found, the message says where it looked (the folder named, or
every default folder the scan reads) and which folders it expects. The
CurseForge folder is joined one component at a time, so its path no longer
shows mixed separators on Windows.

SulfurCube.mobInteract ends with Bucketable.bucketMobPickup, and a sulfur
cube is picked up with an empty bucket (canBePickedUpWithBucket), not a
water bucket. Horizon's bucket pickup only knew the water bucket's mobs,
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
bucket now plays the sulfur fill sound, fills a sulfur_cube_bucket, fires
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
sulfur_cube_content when it has one. Other species keep their bucket data.
The command harness gets a mob_interact op: the connected player's real

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 command returns. Horizon set the mob's health to 0 and left the death
to the next tick's creature phase, so its entity_die vibration reached a
sculk sensor one tick late.
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,
the vibration, the catalyst, loot, experience and kill credit now happen
during /kill instead of in the next creature phase. A second kill and the
next tick do not run it again. The body's removal timer is unchanged.

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

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

/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.

The workflow's clone is blobless, so `git cat-file -e` on a head it
does not hold fetches it from the server, one round trip per check.
On busy days the job ran into its 10-minute timeout. Check every head
in one `cat-file --batch-check` with lazy fetching off, and run the
diffs on 8 threads so their blob fetches overlap. A note for #11723

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
written even when empty.

`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.

A dedicated server's slow tick lines on the SMP show 1-2 s ticks whose

/clone placed the blocks but not the block ticks pending in its source

cmd_clone now calls the existing LevelTicks::copy_area with the source

`AbstractCubeMob.CubeMobKeepOnJumpingGoal.canUse` is

An Allay loaded with a finite minecraft:liked_player memory kept it
forever and saved it without its ttl: the loader read only the memory's
presence and value, the save wrote the value, and nothing counted the
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.

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

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

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 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 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.

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.
Separately, `bench -1` or `bench nan` panicked the game in
Duration::from_secs_f64; bench now takes 0 to 86400 seconds and refuses

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

remote_chunk_in_range added 3 to the radius and subtracted the centre,

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

Any other local user or process that found the port first got the

pcp_map and natpmp_map now refuse a zero lifetime when they asked for

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.

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

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

`FrogAi.initCoreActivity` builds the brain's core activity with

`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

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.

The saved sky and block nibble layers are already the resident Light::Sky and Light::Block layout. Choose the resident variant from the layers and copy the stored layer when only one kind of light varies, so only sections where both vary still expand their light into a full array. Missing layers still inherit the bottom row above and dimensions without sky light still ignore saved sky layers.

1.21.2 dropped the generic./player./zombie. attribute prefixes, so the id tables of 1.21.1 and 1.20.6 (matched by
name) had no attribute runs and every update_attributes value was left out for those clients. They are regenerated
with the renames. Mob effect ids were never renumbered: update_mob_effect and remove_mob_effect now go through the

read and write through the client's ids. 1.21.1's step read the knockback as three doubles where 1.21.4's step
leaves a double and two floats. 1.21.1's strength is 26.3's radius instead of a fixed 3.0.

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
horizon-data.bin, and only after that slow start. The launcher now writes it
in the background once an install or import has its resources, reading on up
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.
A reused version no longer copies the data file, which names its own root.
complete_assets removes the file when it adds something, as the file answers
missing for what it lacks. A write removes what a stopped writer left.

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`).

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.

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.
A block edit relit in the frame changes light up to 15 blocks into the
columns around it, but only the edited column was marked unsaved. With
eager saves a neighbour saved a moment earlier kept its old light on disk.
Vanilla's ChunkHolder.sectionLightChanged marks every chunk whose light
section changed unsaved; mark_light_changes now does the same.

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.
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.
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.

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.
A cushion is an ordinary entity in vanilla (a BlockAttachedEntity), but
Horizon had no command target for it: @e never matched one, so execute
if entity, tag, data get, tp and kill missed every cushion. Target::Cushion
joins the level's candidates like a painting; /kill removes it with no
drop and lets its rider go, /tp moves it with its block, data get writes
it through cushion_to_nbt.

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.

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

Vanilla's Player.aiStep widens the pickup area to the union with the vehicle's box while riding; ExperienceOrb.tick keeps its followingPlayer until they leave 8 blocks, runs scanForMerges in its own turn before the move, and floats by the eye's fluid rather than the feet's block. Fixes#11389.

`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
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.

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`.
Left in the air at y 163, the player fell into the sea below while prepare() ran, which unlocked the boat
recipes: their toast showed over the first shots at a different moment each run, so main against itself
failed in the top right corner.

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.
757/757 cases match the pinned client.
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.

`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

A ledger build from today's upstream/main reports seven map gaps, all rows

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.

This number goes down as gaps close (`tools/parity_gaps.py`); the table below says what the harnesses compare.
The table is the project's own audit: every subsystem matches vanilla in every harness that compares it. 100% means 100% of what the harnesses compare, not that nothing else differs. What players still run into: [known issues](docs/known-issues.md).
The table is the project's own audit of what the harnesses compare, subsystem by subsystem: a score says how much of that subsystem the harnesses cover and pass, not that nothing else differs from vanilla. What players still run into: [known issues](docs/known-issues.md).
### Java parity: 100%
### What the harnesses compare
Scores: 0 (absent), 0.25 (started), 0.5 (playable, major features missing), 0.75 (mostly complete) or 1 (complete and verified by differential tests); the percentage is their average. Last audited 2026-10-13: the harnesses pass on Linux and macOS. The [port ledger](tools/port_ledger.py) adds a method-by-method view of what is ported.

"Microsoft Software License Terms, Microsoft DirectX Shader Compiler" (`LICENSE-MS.txt` of that release). Its
Distributable Code terms are the Windows SDK's: end users get terms that protect the code and Microsoft at least as
much, and the distributor indemnifies Microsoft. The project accepted them on 2026-11-08. Its open-source part is also under the University of Illinois/NCSA license (`LICENSE-LLVM.txt`). Both
files ship beside the DLL as `DXC-LICENSE-MS.txt` and `DXC-LICENSE-LLVM.txt`, with `DXC-NOTICE.txt`
(`packaging/windows/`), which tells players those terms apply and that deleting the DLL brings back FXC.
