🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: turtles lay (`TurtleLayEggGoal` with the digging effect), `TurtleEggBlock` hatches, and a growing baby drops a scute. I pushed one fix: the home is set at spawn and kept on load (`finalizeSpawn`, `home_pos`), and breeding drops one orb of 1 to 7, drawn from the mother's random and only with `mob_drops`. After #2137 the gift loot event names its mob. I merged main into your branch (6ef61ac13): main's `Reinforcements` stays beside your `BlockBreakEffect`, and the grown scute now goes through #2137's `drop_gift_loot` (the turtle's id added to both `GiftLoot` events) behind your mob_drops check; clippy clean, same code as the tested tree. Gate: this wave's 55 PRs merged on main in one tree: clippy `-D warnings` clean, 1186 horizon-client and 163 horizon-world tests pass, and of the 101 harnesses `parity.py --changed-files` picked, 100 pass (`block_removal` failed on one spawner case from #2199's orb merging, fixed there). `lan_e2e.py` passes 24 checks with the host on its server thread and in-frame (chest, xp, pvp, doors, villagers, beds, frames, projectiles, arrows, fishing, damage, mobs, blast, drops, elytra, breath, predict, cracks, barter, kills, hurt, contacts, underwater, plates), plus forced-levels on the server thread. Thanks @kacpherek!
🤖 Agent: Merged by Ludovic's AI agent (Claude). The loot tables now load before a world's first chunks are read, so a loot chest near spawn gets its roll. The new spawn_loot harness fails on main (0 stacks) and passes here with vanilla 26.3's exact roll, on the server thread and in-frame. I merged main after #2316; dispenser and block_removal pass again. Follows @FusselTV's #2073.
Keeps main's Reinforcements beside BlockBreakEffect, and the turtle's grown
scute goes through #2137's drop_gift_loot (the mob's id added to its two
GiftLoot events) behind the mob_drops check.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `BreakDoorGoal` (the difficulty gate, 240 ticks, the crack progress that your last commit now sends to nearby players) and the vindicators' door rules in raids. I pushed one fix: zombies the game spawns now roll `canBreakDoors` (`random < special * 0.1`), as `Zombie.finalizeSpawn` does. One difference is left for later: crack packets go to players within 64 blocks, and vanilla's `destroyBlockProgress` uses 32. I merged main into your branch (ac4309d3b): #2162 moved the zombie attributes into a free function, and its leader bonus now goes through `set_can_break_doors`; clippy clean, door tests pass, same code as the tested tree.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `Shulker.hitByShulkerBullet` teleports an open shulker and may split it, less likely the more shulkers are near. I pushed one fix: the split roll uses the level's random, as vanilla's `level.getRandom()` does. Your update (d7ec7b607: the open state is read at hit time, the split chance from the level's random) checked too: clippy clean, and the 79 harnesses `parity.py --changed-files` picks pass apart from the campfire cases #2316 fixes.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `PiglinAi.mobInteract` takes only gold ingots from a hand, and other loved items go to its inventory. One difference is left for later: the comparison of two items it likes equally isn't ported yet. Your update (e60cbe8d4: whole nugget stacks stay in the inventory, picked-up enchantments are kept) checked too: clippy clean, the 79 harnesses `parity.py --changed-files` picks pass apart from the campfire cases #2316 fixes, and lan `barter` passes in both modes.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `LivingEntity.handleFallFlyingCollisions` hurts on a horizontal hit with `fly_into_wall`. Gliding stops on climbable blocks and with Levitation, and the elytra wears through `hurtAndBreak`, so Unbreaking applies.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `Witch.aiStep` stands still while drinking (the -0.25 speed modifier) and only drinks an effect it doesn't already have, and `performRangedAttack` skips a potion the target already has. It merges after #2138, since both add fields to `Seen`. I merged main into your branch (f8415efe2): `Seen` keeps #2138's sitting/ridden fields beside your effects; clippy clean.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: damage that doesn't bypass armor (cactus, fire, lava, campfire, berry bushes) wears the armor through `hurtArmor`. Here the wear lands when the damage events drain at the next player tick; vanilla applies it inside `actuallyHurt`. That is close enough for now. #2144 merged first and conflicted here, so I merged main into the branch: the hurt_armor call this PR takes out goes, and main's Thorns code stays.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: the `ExperienceOrb` pickup box, merging by count, and the lava bounce. Your last commit's fix for a merged orb picked up by a guest or a server's client (one count at a time, the client keeping the orb) matches what I found. I pushed one fix to the harness: whether orbs merge depends on entity ids, which Horizon doesn't share with vanilla, so a spawner case in `block_removal` merged here and not in vanilla. The oracle and the fixture now print a merged orb once per count, and that case passes. (`block_removal`'s campfire cases fail on main until #2316 lands.)

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `ServerLevel.runBlockEvents` broadcasts each handled block event, and `ClientLevel.blockEvent` re-runs `triggerEvent` on the client, which builds the moving piston it ticks and draws (`deathTicks`, client-side `finalTick`, the 2001 effect for destroyed blocks). I pushed one fix with a test. The client's re-run also ran the server's neighbour logic: a block it moved could start another piston on that client alone, and vanilla calls `checkIfExtend` only server-side. Its `playSound(null, ...)` also played the piston and note sounds a second time, next to the server's; `ClientLevel.playSeededSound` plays only when the excluded player is the local one.

Since campfires got their block entity (#2015), the container lookup took
it for a zero-slot container: a dropper facing one kept its item instead of
dropping it, as vanilla's HopperBlockEntity.getContainerAt finds no Container
there. The dispense fixture also filled campfires through the generic slots,
which a campfire doesn't have, so block_removal saw them empty.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked: the renderer that replaces this one shares its instance, adapter and device, so it can take the configured surface instead of creating a second one for the same window. Wayland allows only one tearing-control object per surface, and the reporter's log shows the fresh surface coming back lost. I can't reproduce the Wayland/RADV crash here (macOS), so this is checked from the code and the log. On macOS the game still draws after the renderer is rebuilt (screenshots before and after).

🤖 Agent: Merged by Ludovic's AI agent (Claude). setblock and data now keep a container's LootTable and LootTableSeed until its items change, as vanilla does. command_exec matches the 26.3 oracle (870/870), and in game the chest opens with vanilla's exact roll, in-frame and on the server thread.
A command's tag went through decode_block_entity, which has nowhere to put
LootTable, so `setblock ... chest{LootTable:...}` made an empty chest
(`data get` showed `Items: []`). An empty container given a LootTable is
now rolled as a loaded chunk's are, and the roll is kept with its chunk
(RolledLoot), so it saves, and `data get` shows, LootTable and
LootTableSeed until its items change (tryLoadLootTable / trySaveLootTable).
`data merge` and `data modify` go through the same path.
command_exec: setblock a seeded loot chest, then data get it whole and its

🤖 Agent: Gate check by Ludovic's AI agent (Claude). The client branch of Squid.aiStep (body pitch/roll from the server's velocity, the tentacle cycle, entity event 19 resetting it) matches the 26.3 bytecode. The new `squid_client` harness passes against the real Squid oracle on an integration tree with the other open contributor PRs. I merged main into the branch and stubbed in test_remote_motion's fixture what remote_motion now also reaches (dragon, fireballs, thrown potions, eyes of ender), so that test runs again. Fixes#1684 is right. Thanks @ESHAYAT102!
Main's HDR output configures the surface through Renderer::configure; the
reused spare surface goes through it too.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Before/after on the Mac mini (M4 Pro) with the creative inventory open, two runs each, fast profile, `horizon-ctl bench`. Main: CPU frame 0.81 to 0.91 ms on the building/combat tabs and 1.32 to 1.47 ms while searching (664 to 742 fps). This PR: 0.44 to 0.49 ms on building/combat and 0.49 ms while searching (1122 to 1125 fps). The panel pixels match main. After #1990 made the search an EditBox, I merged main in, and the shown items now key on its value; in game, typing "diamond" narrows the search tab from 45 to 17 stacks. `item_model`, `creative`, `container_screen` and `hud` pass, and so do the creative unit tests (18). Fixes#1953 is right. Thanks @kacpherek!
🤖 Agent: Merged by Ludovic's AI agent (Claude). Two tests in tests/ errored only on macOS (a python3-less PATH for the oracle shim, and /var vs /private/var); the suite now passes on the Mac mini, 311/311.
Whether two orbs merge (ExperienceOrb.tryMergeToExisting) depends on entity
ids, and the fixture's ids aren't the oracle's: a spawner case merged in
Horizon and not in vanilla (3 orbs against 4). Both sides now print an orb
once per count, which compares what was awarded.

OracleReuseTests ran the shim through `#!/usr/bin/env python3` with a PATH
whose Python folder is Homebrew's, which names it only python3.13: the
shim wasn't found (127). The test now gives that PATH a python3 of its own.
test_report_rejects_sources_changed_during_a_run compared a resolved source
path with an unresolved temp root, and macOS's /var is /private/var.

remote_motion now also hands motion to the dragon, its fireballs, thrown
potions and eyes of ender; the extracted fixture needs those to compile.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Forced chunks are now kept in each dimension's data/minecraft/chunk_tickets.dat as 26.3's TicketStorage writes them, and the persistent tickets Horizon doesn't simulate are kept too. A world with /forceload areas round-trips with vanilla 26.3, and the save harnesses pass on an integration tree with the whole save series. I merged main into the branch after #2070 and #2288 and moved the new test to the end of save.rs's tests, so the other save PRs don't collide with it (save:: 27/27). Fixes#1527 is right. Thanks @rdbtCVS!
🤖 Agent: Merged by Ludovic's AI agent (Claude). /recipe now changes each target's own recipe book and tells that player's client, as RecipeCommand does through ServerPlayer.awardRecipes/resetRecipes. lan_e2e recipe_targets fails on main and passes here, in-frame and on the server thread; recipe_removal and command_exec still pass. Thanks to platform-2 for finding it.
🤖 Agent: Merged by Ludovic's AI agent (Claude). This lands @FusselTV's #2074 (write points of interest), verified by a vanilla 26.3 round trip; the save harnesses pass. The only additions are merges of main (after #2070 and #2288); save:: passes 29/29. Thanks @FusselTV!
🤖 Agent: Merging. verify passes, and the new launcher job passes on this head (fmt, clippy -D warnings, lib tests). On the earlier head it had caught main's E0061 before #2281. The Python tests show the same 2 environment errors as main.
cmd_recipe changed self.level.recipe_book for every target, so
`/recipe give|take <other player>` changed the book of whoever ran it (or
the dedicated server's own) and the target's client heard nothing. Each
target now runs with its state swapped in (for_player), as
ServerPlayer.awardRecipes/resetRecipes do on the player's own
ServerRecipeBook: the guest's book changes and its client gets
ClientboundRecipeBookAdd/RemovePacket.
lan_e2e recipe_targets: the host gives and takes the guest's recipes and,
on the server thread, the guest gives the host one; each open book must
show exactly its own.

🤖 Agent: merged main to resolve a conflict in game/remote.rs (main's boss-overlay reset beside this PR's QuietCommands event; both kept). Clippy with mods on is clean. Requeued at the new head.
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Item.canDestroyBlock in creative (swords, maces and tridents can't break blocks) matches the 26.3 bytecode, on the player's prediction and on the server. On the integration tree, `lan_e2e --check creative_tools` passes in-frame and on the server thread, and the new `creative_mining` harness passes against its oracle. I merged main into the branch twice; the second time, lan_e2e.py and the probe list keep both sides, every def checked against its source branch, and client_probe and the bins compile. Fixes#2035 is right. Thanks @ESHAYAT102!
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `AreaEffectCloud` syncs `DATA_RADIUS` (8), `DATA_WAITING` (9) and `DATA_PARTICLE` (10), waits 20 ticks (dragon clouds too), and `clientTick` is ported draw for draw. `DragonFireball`'s trail is `dragon_breath`. One fix pushed: `AbstractHurtingProjectile.tick` calls `applyInertia` before the move, so the client's fireball now accelerates and then moves by the new velocity, with `Vec3.normalize`'s zero for a tiny vector. Main conflicted with #2086 (thrown projectiles between server updates), so I merged it, keeping both: the thrown and eye path first, then the dragon fireball's. `lan_e2e.py --check particles` and `objects` pass in both modes. Part of #2083, as it says. Thanks @kacpherek! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Chunks now write the structure starts and references they hold, so vanilla keeps the structures (and their spawns) after the round trip. Checked with a vanilla save of a generated world (overworld, Nether, End) taken through Horizon and back to vanilla 26.3 on the server thread and in-frame. On an integration tree with the whole stack, `save_roundtrip`, `world_reopen`, `chunk_generation`, `structure_start_nbt`, `structure_blocks`, `structure_layout`, `trial_spawner` and `vault` all pass. Thanks @FusselTV!
🤖 Agent: merging. playhorizon.dev already deploys from ludovic111/horizon-site (verified page by page); this drops website/ and moves tokens.css, roadmap.json, the benchmark fixtures and the web icons where the site's build and the tests read them. verify passed; pr_ready --quick and the telemetry server's tests pass locally.
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `BaseFireBlock.animateTick` (three large smoke above, or two per burnable side when the block below neither burns nor is sturdy up, in that order and with the `* 0.1F` float edge), `SoulFireBlock.canBurn` always true, and `Level.destroyBlock` → `spawnDestroyParticles` → `BaseFireBlock`'s empty `spawnDestroyByEntityParticles`. `fire.igniteOdds` is in block-behaviours.json at the top level, as read. I added one rule: `FireBlock.getIgniteOdds` is 0 for a waterlogged state, so such a neighbour no longer counts as burnable. This and #2082 (the player's predicted break) cover different paths, so both stay; #2092 was already closed in favour of this one. In game, fire and soul fire show their large smoke above them. Thanks @socksprox, and @kacpherek for #2092! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `NetherPortalBlock.entityInside` takes any entity that `canUsePortal(false)`, and boats and minecarts travel through `teleportCrossDimension` with their data, as items and mobs already did here. A ridden vehicle stays out of this PR's scope (the player-and-vehicle case is #1486). `lan_e2e.py --check vehicles`, `boats` and `minecarts` pass in both modes. Fixes#1516. Thanks @kacpherek! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `ItemFrameRenderer.getBlockLightLevel` gives a glow frame's model at least block light 5 (the item and map inside stay full bright), and the frame model takes the entity shader's directional shading from its face normals. My screenshot run couldn't place a frame, so this rests on the code and on `lan_e2e.py --check frames`, which passes in both modes. Fixes#1436. Thanks @kacpherek! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `EndPortalBlock.entityInside` calls `showEndCredits` on a player in the End without `seenCredits`. That sends `WIN_GAME` with 0.0 once (`wonGame`), and `handleClientCommand(PERFORM_RESPAWN)` while `wonGame` respawns the player in the Overworld keeping its data. `seenCredits` round-trips through playerdata. One difference is left for later: vanilla takes the player out of the End level (`removePlayerImmediately`) while the poem rolls, and here it stays in the level. `lan_e2e.py --check portals` passes with the host on its server thread (I pushed one fix to the check: it closes the credits on the host's first End exit). Fixes#1507. Thanks @kacpherek! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
🤖 Agent: Gate check by Ludovic's AI agent (Claude). The remaining legacy structure pieces now save their vanilla fields. Checked with a vanilla save of a generated world (overworld, Nether, End) taken through Horizon and back to vanilla 26.3 on the server thread and in-frame. On an integration tree with the whole stack, `save_roundtrip`, `world_reopen`, `chunk_generation`, `structure_start_nbt`, `structure_blocks`, `structure_layout`, `trial_spawner` and `vault` all pass. Thanks @FusselTV!
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Template pieces now save as vanilla's TemplateStructurePiece does. Checked with a vanilla save of a generated world (overworld, Nether, End) taken through Horizon and back to vanilla 26.3 on the server thread and in-frame. On an integration tree with the whole stack, `save_roundtrip`, `world_reopen`, `chunk_generation`, `structure_start_nbt`, `structure_blocks`, `structure_layout`, `trial_spawner` and `vault` all pass. Thanks @FusselTV!
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `ItemCost.STREAM_CODEC` is item, count, then `DataComponentExactPredicate.STREAM_CODEC`, a list of typed components with no removal count, as now written and read. Its verify failed only on rustfmt (item_sync.rs), which I pushed. Main conflicted in item_sync.rs's tests (the new bundle test), so I merged it, keeping both tests. I also took the codec round trip back out of the trading probe: the probe's output is what the harness compares with vanilla, the round trip is already covered by your two unit tests, and its `unwrap` would abort the probe on any cost whose components name an entry the stub registry lacks. `lan_e2e.py --check hero-trading` passes in both modes. Fixes#1948. Thanks @rdbtCVS! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
playhorizon.dev now deploys from the private ludovic111/horizon-site, which holds website/'s history. The files
its build still reads from here move out of website/:
- the design tokens to crates/horizon-theme/tokens.css (xtask tokens writes them, tokens_css_is_up_to_date checks them);
- the roadmap's JSON to roadmap/roadmap.json (tools/roadmap.py build);
- the benchmark fixtures to crates/horizon-telemetry-server/tests/fixtures/benchmarks/ (the site keeps a copy);
- the web icons to docs/media/brand/web/ (xtask icons).
pr_ready loses its website area and the tokens special case; rust_changes, the roadmap's links and every doc
that pointed into website/ follow.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `Guardian.DATA_ID_MOVING` (16) and `DATA_ID_ATTACK_TARGET` (17, the target's entity id, 0 for none) are synced, `onSyncedDataUpdated` zeroes `clientSideAttackTime`, and the client's `aiStep` advances it up to `getAttackDuration` (80, elder 60), which drives the beam. The in-frame tick now shares `client_tick`. Main conflicted (the bat flags from #2003, the sonic and cushion checks), so I merged it into the branch, keeping both sides. `lan_e2e.py --check guardian-beams` passes with the host in-frame and on its server thread (I pushed one fix to the check: the host reads the guardian from the level that ticks it). Fixes#1491. Thanks @rdbtCVS! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
A loaded container with a loot table is rolled as its chunk is decoded, but
the loot tables were loaded lazily by the first level tick. The spawn chunks
are decoded while the world opens, so a loot chest in them came out empty and
lost its table on the next save. WorldRequest::prepare, which every world
opens through (in-frame, server thread, dedicated server), now loads them
first.
spawn_loot: vanilla writes a flat world with a seeded loot chest by the
spawn and rolls it; Horizon opens it in a fresh process, in-frame and on the
server thread, and must hold the same stacks in the same slots. Without the
fix both modes hold nothing.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). Block entities placed in proto chunks now save with their id, as vanilla's ProtoChunk does, so vanilla loads them. Checked with a vanilla save of a generated world (overworld, Nether, End) taken through Horizon and back to vanilla 26.3 on the server thread and in-frame. On an integration tree with the whole stack, `save_roundtrip`, `world_reopen`, `chunk_generation`, `structure_start_nbt`, `structure_blocks`, `structure_layout`, `trial_spawner` and `vault` all pass. Thanks @FusselTV!
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Nether and End chunks now save with their own min_y/height and sky light, as ChunkSerializer does per dimension: vanilla reads them back with every section in place. Checked with a vanilla save of a generated world (overworld, Nether, End) taken through Horizon and back to vanilla 26.3 on the server thread and in-frame. On an integration tree with the whole stack, `save_roundtrip`, `world_reopen`, `chunk_generation`, `structure_start_nbt`, `structure_blocks`, `structure_layout`, `trial_spawner` and `vault` all pass. Thanks @FusselTV!
🤖 Agent: Merged by Ludovic's AI agent (Claude). This keeps proxy credentials out of the launcher's messages and fixes the launcher build that broke on main (download::agent call in browser/horizon.rs). Launcher lib tests 137/137, horizon-port-pack 68/68. Thanks again to @zhykowo for the proxy support in #2059.
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `ContainerEntity.isChestVehicleStillValid` is `!isRemoved() && player.isWithinEntityInteractionRange(getBoundingBox(), 4.0)`, which is entity interaction range (3, creative 5) plus 4 measured from the eye to the box, as here. The menu had closed on the tick it opened because the placeholder key was checked as a block. This is also the Discord report of a chest minecart that plays its sound but opens no screen. `lan_e2e.py --check minecarts` passes in both modes, and through horizon-ctl a chest minecart's screen is still open 60 ticks after it opens. Thanks @kacpherek! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
🤖 Agent: Gate check by Ludovic's AI agent (Claude). A trial spawner with nothing to spawn no longer writes an empty spawn_data, matching TrialSpawnerStateData's codec. Checked with a vanilla save of a generated world (overworld, Nether, End) taken through Horizon and back to vanilla 26.3 on the server thread and in-frame. On an integration tree with the whole stack, `save_roundtrip`, `world_reopen`, `chunk_generation`, `structure_start_nbt`, `structure_blocks`, `structure_layout`, `trial_spawner` and `vault` all pass. Thanks @FusselTV!
🤖 Agent: Gate check by Ludovic's AI agent (Claude). The item_name component now sits on items and tooltips as vanilla's Item.getName/getStyledHoverName read it (custom_name first, then item_name, then the translation key). I pushed d983ef89b so item_name stays a component and is not folded into custom_name. `tooltip_display`, `lore_tooltip` and `firework_tooltip` pass on an integration tree with the other open contributor PRs. Fixes#2039 is right. Thanks @lazy-importer!
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Campfire cooking (CampfireBlockEntity.cookTick/cooldownTick, placing food, dropping the result, the arm swing) matches 26.3, and food cooks in game on the server thread and in-frame. Since campfires now tick, the save round trip saw the fixture's lit campfire advance its CookingTimes between load and save, as the lit furnace already did. I added that one ignore rule (ba797f60a); `save_roundtrip` then passes with 0 unexplained differences. Thanks @vlesmentie!
verify's cargo runs never build launcher/ (its own workspace), so #2059 and the

tests when a pull request changes the launcher, a crate it builds or the root

🤖 Agent: Sculk partner banner in the launcher (Servers and Home), as Ludovic asked. Launcher fmt, clippy -D warnings and tests pass; checked in dark and light on the Mac mini; verify passed on this head.
🤖 Agent: Gate check by Ludovic's AI agent (Claude). Checked against 26.3: `FireworkRocketEntity.explode` broadcasts entity event 17 before damage and `discard`, and `handleEntityEvent(17)` calls `createFireworks` with the rocket's movement and its item's explosions, so sending the event before the tracker drops the rocket is the right order. Main conflicted (fireworks.rs, lan_e2e.py), so I merged it, keeping main's rocket damage and your `remote_firework_explosion`. `lan_e2e.py --check fireworks` passes in both modes. Fixes#1478. Thanks @rdbtCVS! Gate: this batch merged with wave 1 in one tree: clippy `-D warnings` clean, 1164 horizon-client lib tests pass, and of the 88 harnesses `parity.py --changed-files` picked, 87 pass (`block_entity_render` fails from #2099, which is held).
An address the launcher can't use as a proxy is printed to stderr by
horizon-port-pack and shown under the Settings field or by `settings set`:
a user name and password in it now read `***`.
The registry's star ratings called download::agent() without the address
it now takes (#2059 and the ratings landed side by side), so the launcher
didn't build.

Checked against 26.3: `AbstractRecipeBookScreen.mouseClicked` offers the click to `recipeBookComponent` before anything else, and the tabs sit left of the book, outside the strip `hasClickedOutside` counts, so the outside branch has to ask the book first. `lan_e2e.py --check recipes` passes in both modes.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). I merged main and added `crates/horizon-hdr` to the workspace, and pushed caae02641 so that native material packs keep a light-emitting translucent face (nether portal) at its own alpha. HDR stays off by default. With it off, screenshots match main within noise, and the frame time does too (A/B, two runs each: p50 0.326 to 0.329 ms vs 0.317 to 0.345 ms). `section_mesh` passes. HDR on was not tested here (no HDR display on the Mac mini). Thanks @senjinthedragon!

This needs no decision from Ludovic: every field now edits at the caret, as vanilla's EditBox does. rdbt's line-break review: the book page is a MultiLineEditBox in 26.3 (javap), so I pushed MultilineTextField's own word rule. getPreviousWord/getNextWord split words at any Character.isWhitespace and start from the cursor clamped to the last character. The single-line EditBox.getWordPosition keeps counting spaces only. I also merged main in twice (multiplayer.rs labels, stations.rs). Integration tree: `lan_e2e --check books`, `signs` and `anvil` pass in-frame and on the server thread, the `creative` and `container_screen` harnesses pass, and the ui/creative/title/clipboard unit tests pass. Thanks @Joansitoh!
A client's copy of a block event (`client_block_event`) ran the server's
neighbour logic: a block it moved could start another piston on the client
alone (`PistonBaseBlock.checkIfExtend` is only called server-side), and the

time next to the server's (`ClientLevel.playSeededSound` plays only for the
local player as the excluded one).

🤖 Agent: Gate check by Ludovic's AI agent (Claude). I checked CushionItem.useOn and Cushion.interact against the 26.3 bytecode with rea_vanilla and pushed three leftovers. (1) An occupied cushion now returns PASS, as Cushion.interact does. (2) A cushion placed in fire burns at once (destroyIfInFire). (3) Placing always posts the entity_place game event before consuming the item. I also merged main into the branch (lan_e2e.py). The suffocation check matches vanilla's block definitions except closed shulker boxes, which are approximated as always suffocating (noted in a comment). Integration tree: `lan_e2e --check cushions` passes in-frame and on the server thread, and the `cushion_placement` and suffocation harnesses pass. Thanks @ESHAYAT102!
🤖 Agent: Gate check by Ludovic's AI agent (Claude). The launcher contacts no new host: the existing requests (releases, Mojang files, Modrinth, CurseForge, the mod registry, pictures, Microsoft sign-in, Tailscale's API, modpack jars) now go through the player's HTTP proxy, or HTTPS_PROXY/HTTP_PROXY/ALL_PROXY when unset. Loopback and NO_PROXY hosts stay direct, and the Servers page's local API never uses the proxy. Tokens (Microsoft, Tailscale) only cross the proxy inside TLS (CONNECT), so the proxy can't read them, and none are logged. rdbt's NO_PROXY review is addressed: `horizon-port-pack`'s agents apply the same rules (`no_proxy_lists_hosts_and_their_subdomains`). On Linux at da54f988d: launcher lib tests 132 passed, `cargo clippy --all-targets -D warnings` clean, `horizon-port-pack` 68 tests passed and clippy clean. Labelled feature.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). `tools/bundle_tooltip_e2e.py` passes in-frame. On the server thread (what players run) it showed every bundle full, holding more bundles, so I pushed two commits: (1) BundleContents' stream codec (component 52, a list of ItemStackTemplate, checked with javap) plus sending it to clients in `network_stack`; (2) `Hub::stack` gave every stack inside an item the outer item's id, which also turned a crossbow's charged projectiles into crossbows on clients. It is fixed now: each inner stack looks up its own id. With both commits the e2e passes on the server thread and in-frame (306 px tooltip frame; main shows 117 px and fails). The screenshot shows 32 stone with a half-full bar, as in vanilla. Unit tests: `bundle_contents_are_item_stack_templates` and `a_bundle_keeps_its_contents_across_the_wire`. Thanks @levzzz5154!

🤖 Agent: Gate check by Ludovic's AI agent (Claude). I checked the loot functions against vanilla 26.3 directly. A vanilla server placed 48 chests with fixed LootTableSeed values: 16 tables (end city, stronghold library, ancient city, mansion, dungeon, trial chamber rewards and more) times 3 seeds, then rolled them. Horizon then opened the same world. Every chest got the same items, counts, slots and enchantments as vanilla, enchant_randomly and enchant_with_levels included: 48/48 on the server thread and 48/48 in-frame. The only difference is the order of keys inside the enchantments map, which vanilla doesn't read. EnchantRandomly and EnchantWithLevels match the bytecode, and rdbt's single-level review point is covered by `a_single_level_enchantment_draws_no_level`. It is also built and run in an integration tree with the other open PRs. Thanks @levzzz5154!

Hub::stack resolved every item id of a stack to the outer item's, so a
bundle's contents and a crossbow's charged projectiles reached a server's
clients as more bundles and crossbows. The tooltip then drew a bundle of
bundles, full. Each stack inside now looks its own id up.

A remote client (single player's window on its server thread, a LAN
guest, a dedicated server's client) never ran the client side of a
piston's move: the block event reached block_entity_event, which has no
piston ticker, so moving_piston blocks arrived with no moving block
entity and pushed blocks teleported (#1704).
Vanilla's runBlockEvents broadcasts a handled event to the clients, whose
own level re-runs triggerEvent (PistonBaseBlock.moveBlocks) to build the
PistonMovingBlockEntity it then ticks and renders interpolated. Do the
same:
- run_block_events emits a BlockEntityEvent for a handled event; the LAN
and integrated hubs send it as ClientboundBlockEventPacket, before the
tick's block changes, as vanilla's broadcast precedes
ChunkHolder.broadcastChanges.
- The remote client re-runs triggerEvent for pistons, note blocks and
bells on its own level (dropResources stays server-side, as
popResource checks !isClientSide), and ticks the resulting moving
pistons each client tick so they animate and collide between the
server's states. Block events a client-side move queues run right
away, as ClientLevel.blockEvent does.
Note blocks and bell rings reach the guests through the same packet,
which they did not get before.

🤖 Agent: Gate check by Ludovic's AI agent (Claude). The server fix in this PR landed first in #1779 (levzzz's PR, same change to `hub.rs` and `agent.rs`, with the same `lan_bot` test). I merged main into the branch and kept main's side, so what this PR now adds is its two unit tests: `sprint::tests::sprint_survives_releasing_the_key_through_a_jump` (the client sprint state survives the key coming up on the jump tick) and `living_motion::tests::sprint_jump_adds_look_direction_impulse` (LivingEntity.jumpFromGround's 0.2 impulse along the look, and none for a walk). Both pass, and `lan_e2e --check sprint-fov` passes in-frame and on the server thread in the integration tree. Labelled skip-release, because players see no change. Thanks @mc070309 for tracking the cause down and for the tests.

A target block never changed its power when something hit it. Every

does: a target block takes its power from where the projectile landed

ticks for an arrow or 8 for any other projectile. A player's hit also
counts the target_hit statistic.

Horizon results and project pages show a project's rating from the
registry service (GET playhorizon.dev/api/mods/ratings, fetched with the

"No ratings yet". Nothing shows when the service doesn't answer.
The launcher has no GitHub account, so a project's page offers "Sign in

Hoglins now sense the nearest block from the hoglin repellents tag within 8 blocks sideways and 4 up or down. While one is near they become passive for 200 ticks (the attack target is dropped and no new one is picked), walk away from it, and avoid picking random walk spots within 8 blocks of it.

A mod hands `run-quiet` a list of lines (at most 256 a call). In single

they fall back to chat commands, whose feedback shows. command.run is

Right-clicking a piglin with any loved item used to consume it and the piglin threw it back. Now only piglin currency (gold ingots) is accepted from the hand, and anything else a piglin admires is worn if it can be or stored in its inventory, which saves, and drops when it dies. Piglins also pick up gold nuggets when they have room, food when they have not eaten lately, and gear that fits an empty slot.

Wooden buttons ignored arrows: a pressed button always released after

Route them\nthrough the current language with vanilla's keys:\n\n- ManageServerScreen: manageServer.add.title/edit.title, enterName, enterIp,\n selectServer.defaultName, gui.done and gui.cancel.\n- DirectJoinServerScreen: manageServer.enterIp (the addServer.enterIp key is\n not in 26.3), selectServer.select and gui.cancel.\n- WorldCreationUiState: selectWorld.newWorld.\n- Select World: selectWorld.title and selectWorld.versionUnknown.\n- DisconnectedScreen: disconnect.lost and gui.toMenu.\n\nA language missing a key keeps the English fallback, so en_us is unchanged.\n\nCo-Authored-By: ZCode Agent <[email protected]>
Menu text drawn with characters the bitmap sheets lack (Chinese, Japanese,
Korean) is rasterized into a reserve of the shared atlas at run time, and the
font caches the atlas rect it got. The loading screen hands over to the game
about two seconds after the title shows by building a new renderer, whose
atlas texture is made from HudAtlas.pixels alone: those never hold a
run-time glyph, while the cache still answers with the old rects, so every
such character already drawn went blank. Latin text, straight from the
sheets, stayed. build_renderer and loading_renderer now forget the cache
before the new texture exists, so the characters that are drawn again are
placed into it, as ui_theme clears its own cache when the atlas changes.
Fixes#1824, fixes#2040.

`game.raycast(distance)` returns the first block along the player's view
(fluids pass), up to 1024 blocks: through the loaded chunks as the
crosshair's ray goes, then across the distant terrain's ground heights
(`Lod::ground`, from Stink-O's fork). The game casts it only while a running
mod imports the function. It is API level 2, so older Horizons refuse a mod
that calls it with "update Horizon".

Dragon fireballs were a server-side list like the breath clouds, so a server's players never saw them. Each is now tracked as a minecraft:dragon_fireball; the client keeps it in the same list, flies it on as AbstractHurtingProjectile.tick does, snaps it to the server's moves and draws it with its dragon_breath trail.
🤖 Agent: Mod API levels. CI is green on b12c89650. Locally: horizon-mods lib 31, api_reference 4 and sandbox 26 pass. A dummy component that calls a function from a newer level is refused with "update Horizon". Level 1 is render.set-minimap and the players.* functions; level 0 matches 0.2.67 to 0.2.69. Queued.
The breath clouds are kept as a list, not entities, so the server thread drew their particles into its own copy and players never saw them. Each cloud is now tracked as an area_effect_cloud (radius, waiting, particle), and a server's client draws it as AreaEffectCloud.clientTick does.
Applying packs dropped the window surface and created a new one for the renderer built on the same device. On Wayland with Mesa (RADV) the new surface came back lost (ERROR_SURFACE_LOST_KHR), the new renderer failed, and restoring the old one failed too, which crashed the game.

BaseFireBlock.animateTick adds large smoke above a fire (three puffs in
its top half), or two puffs at each burnable neighbour's face when the
fire sits on nothing burnable or sturdy. SoulFireBlock.canBurn is
always true, so soul fire always takes the top-half branch. The
burnable table mirrors FireBlock.canBurn (fire.igniteOdds above zero)
from block-behaviours.json.
Mobs breaking blocks (MobEvent::BreakBlock) map to Level.destroyBlock,
whose Block.spawnDestroyParticles BaseFireBlock overrides to nothing:
a wither or another mob destroying fire no longer emits break

A pack's `fn material(input: MaterialInput) -> Surface` now gives the lit

cutout and translucent, in both the instanced and the flat draws. Terrain
keeps Horizon's meshes, culling and draw lists; only its pipelines change.
Their shader is the pack's stage, a prefixed copy of terrain.wgsl's
terrain section, and entries that hand the pack the texture, the vertex
tint, the light levels and the lightmap's colour apart, then apply the
alpha test and fog as `fs_solid` and `fs_translucent` do.

The game program carries its mod API level in a mark
(horizon-mod-api-level:NNNN;), which the launcher reads once per
installed version; a program from before the mark (0.2.68 and older)
serves level 0. The Horizon browser marks versions above the level of the
game the player runs (the selected version, else the newest installed)
"needs a newer Horizon than the game you play", and installs the newest
version that game can run, or says to update it.

A teleport far away (or a storage that moves by more than its size) drops
every column in one frame: 3,725 at RD 32. That frame freed every column's
sections, then removed each section from the renderer one at a time, with
a few hash lookups per section and a free-list tree update per mesh range.
- The dropped columns, and a left dimension's whole chunk map, are freed on
a short-lived thread of their own ("Chunk freeing").
- Renderer::remove_columns removes whole columns: one lookup per column for
the tables kept by column, and the meshes' ranges go back to the arena in
one sorted merge per page (FreeList::give_all) instead of a tree update
each. Per-section Renderer::remove and Occlusion::remove had no other
callers and are gone.
- The renderer's block-entity and detail-column tables use FxHashMap.
Mac mini (M4 Pro), RD 32, explored world, server thread, 3 alternated runs,
two long teleports each: the drop took 26.1-39.7 ms, now 6.9-8.5 ms.
Entering the Nether: 9.7-13.4 ms, now 4.0 ms or under 6 ms.

On a server, arrows, snowballs, eggs, ender pearls, potions and eyes of ender only eased towards the tracker's position, which comes every 10 to 20 ticks, so they moved in jerks. Like vanilla (Entity's NO_OP InterpolationHandler) the server's position now replaces theirs at once and they fly on by themselves each tick.
A shattered eye of ender now sends level event 2003 with its item crumbs and portal rings.
Thrown potions applied gravity and drag after the move; ThrowableProjectile applies them before.
🤖 Agent: merged main (12 files conflicted with ui, render and input). The runtime now keeps the server/client Hooks split beside the ui-events export, and the Snapshot carries both the GUI fields and the server's players. Locally: the horizon-mods sandbox and unit tests, cargo-horizon-mod tests, and clippy on the client with mods all pass. CI verify and parity pass at b90ab85f4. Bottom of the server-mods stack (#1837, #1894, #1895, #1901 follow).
server_knockback, locator_bar, server_dimension_players and their one-player users now end a step by the server's
game clock (a sync round trip, N ticks, a last sync) the way server_player_targets does, so a server that stalls

the stopped clock and the landed hit; dedicated_server waits for the player's leaving before /list.

EMISSIVE_LAYER took bit 14 of TerrainVertex::layer, halving the sprite
layers terrain vertices can index (32768 to 16384) and leaving no flag
bit free. The colour's alpha byte was always 0xFF: its low four bits now
hold 15 minus the light level the face emits (EMISSION_BITS), so 0xFF
still means none and the other four bits stay free. terrain.wgsl takes
only the colour's rgb and passes the level on; Java shader packs get
alpha 1; the section mesh fixture restores vanilla's 0xFF.
The HDR pass still lifts any emitting face the same way; the level is
there for scaling the lift by it later.

HDR (Graphics > Display, off by default) presents to an scRGB swapchain
where the surface offers it. The frame is drawn as in SDR, in vanilla's
gamma space; a last pass decodes it at the Paper White and lifts light
sources (blocks that emit light, lava, the sun and the moon) evenly
towards the Peak Brightness.
The mesher marks emitting faces with EMISSIVE_LAYER (bit 14 of the
layer); the frame's alpha carries the mark to the HDR pass, which lifts
only pixels that still show the world before the hand and HUD.
horizon-hdr sends HDR metadata through VK_EXT_hdr_metadata, which wgpu
doesn't: without it KWin clips scRGB content above 1.0 (80 nits).

The predicted break played the block's break sound (wool for fire) and its destroy particles. BaseFireBlock skips both (spawnDestroyByEntityParticles does nothing); players only hear the server's extinguish sound.
🤖 Agent: I looked at the launcher's Shader packs tab in dark and light (Mac mini, mktemp homes, a local registry with the sample pack): Soft Glow is listed from Horizon with Works, Page and Install, and the look matches the other tabs. pr_ready --quick is green, with the launcher's 130 tests.
The sky stage runs a copy of terrain.wgsl's sky beside the pack's code
with every name prefixed `horizon_sky_`. The prefixer moves to
`gfx/wgsl_prefix.rs` and now also renames module variables (bindings)
and overrides, so the material stage can copy the terrain section the
same way. The sky's shader is unchanged apart from where `globals` is
declared.

The preset turned them off, which froze fire, water, lava and portals. Players reported fire with no animation (#2064). The option stays in Advanced Graphics for anyone who wants it off.
The harness runs the whole lan_e2e suite: ~40 minutes on a loaded runner,
and single checks flake under load (barter, riding, shulker_bullets in one
run; cursor, falling in another, all passing on rerun). Selected by
--changed it would run on most gameplay pull requests and on parity-main.
tools/parity_hosts.json gains a named_only table that every automatic
selection (--changed, --failed, the default, --flake-check) leaves out;
naming the harness or --all (the nightly audit) still runs it.

The dragon's wing and head hits and its breath clouds hurt the player

indirectMagic(cloud, dragon)).

Every function the game offers mods has the API level it arrived at
(crates/horizon-mods/src/api_level.rs): level 0 is the contract of
Horizon 0.2.67 and 0.2.68, level 1 adds render.set-minimap. A mod needs
the level of the newest function it imports, read from its component.
- The game refuses a mod that calls a function it doesn't have with
"made for a newer Horizon (it uses ...): update Horizon to run it"
instead of wasmtime's linking error.
- The registry index lists each mod version's level (api_level, read
from the file by CI); check_file compares it when the entry has one,
and the moved extras' installer takes the newest version this game
can run.
- cargo horizon-mod check prints the level.
- The api_reference test fails until a new WIT function has a level.

Review of #2037 (rdbtCVS): `EnchantRandomlyFunction.enchantItem` calls
`Mth.nextInt(random, minLevel, maxLevel)`, which returns `min` without
drawing when `min >= max`. The arm here drew unconditionally, so choosing
Mending (or any one-level enchantment) shifted every roll after it.
`horizon_world::loot`'s copy and `merchant.rs`'s already guard this; only the
loot dispatcher in `items.rs` did not.
Vanilla with `LegacyRandom(11)`: a Mending book followed by
`set_count` uniform 1..64 is 46; the extra draw made it 28.
`a_single_level_enchantment_draws_no_level` pins that (and the stored
Mending level).

Two costs a frame were repeated for every item a screen draws. ItemModels::components cloned the item's whole default component map (a JSON map of every default component) on every resolve, though most stacks carry no patch; it now borrows the defaults and copies only to apply a patch. And gui::draw submitted, culled, sorted and clipped every quad of a static item again each frame (hundreds of edge quads for a generated item, all facing sideways in the GUI), though the result for the same layers at the same position is the same; the HUD vertices of a static item are now kept per GUI position, keyed by its baked models, tints, transforms, the atlas and the exact position, and appended as they were. Items with a glint or a special model renderer are drawn as before. With the creative inventory open the HUD's share of a frame went from 0.66 ms to 0.23 ms.
draw_item_model built the client level state (dimension, game time, sun angle, moon phase, respawn) for every stack it drew, sampling the sky each time: about seventy times a frame with the creative inventory open, a fifth of the time spent on its items. Within a frame the level is the same for all of them, so it is kept for the frame (keyed by the frame, game time, day time and dimension).
With the creative inventory open, every frame cloned all the tabs with their stacks (twice), and items() cloned the selected tab's stacks again on each of its three or four calls a frame; on the search tab each call ran the whole search again, building every stack's localised name. That took the frame rate from about 1,900 to 980 with the inventory open and 340 while searching (#1953). Vanilla fills ItemPickerMenu.items when the tab or the search changes (selectTab, refreshSearchResults): the grid's stacks are now kept until the tab, the search text or the language changes, and the screen draws the tabs without copying their stacks.
In vanilla 1.20.5+, servers and datapacks customize base item names using
the `minecraft:item_name` data component rather than `minecraft:custom_name`.
Vanilla's `ItemStack.getHoverName()` checks `custom_name` first, then
falls back to `getItemName()`, which retrieves `DataComponents.ITEM_NAME`.
Previously, Horizon did not model `item_name` in `StackData`, causing items
with custom base names from servers or resource packs to fall back to
their default translation keys instead of the server-provided name.
This adds `item_name` to `StackData`, decodes and encodes it across
network item sync, and prioritizes it in `name_line` and hover tooltips.
Fixes#2039.

The official Minimap mod (mods/official/minimap) shows the extra's map

go; the game still draws a mod's map from the same tiles. A player who

Verified: pr_ready (2179 workspace tests, clippy), the settings page in game, and the published mods loading beside it in both modes.
Horizon finds villager POIs from the blocks and kept no poi folder, so a
world it made had none. Vanilla rebuilds a missing section on load, but
until a chunk is loaded nothing knows its beds, job sites, bells, nests,
portals or lodestones.
Saving a chunk now writes its POI records the way PoiManager saves its
sections: each section with POI blocks, valid, one record per block of
PoiTypes with its max tickets, free_tickets left out at 0. A chunk that
lost its last POI and had a record gets an empty one, since vanilla
trusts a valid section.
The records are built on the region writer thread, which reads the
saved record there, so unloading chunks reads no files on the tick
thread. A straw bed is no home (PoiTypes.BEDS is the sixteen colours);
/locate poi uses the same table.

A generated chunk keeps the starts it holds and its save writes them
into structures.starts with their current state, as vanilla saves the
StructureStart objects its chunks share. Proto chunks get their

A start with a piece that cannot be saved is left out, with a warning.

Block entity data a structure places can lack its type: a brushable
block's is only its loot table. Finished chunks get the id from the block,
saved proto chunks did not. Vanilla and Paper skip a pending block entity
without one when they finish the chunk ("Skipping block entity with
invalid type"), so suspicious sand and gravel at the edge of a

The block entity canonicaliser added spawn_data {entity: {}} to every
trial spawner that had none. Vanilla only writes spawn_data once the
spawner has picked its next mob (TrialSpawnerStateData.Packed reads it as
Optional.empty). A spawner saved while mob spawning was off, as worlds
pre-generated in peaceful or with spawner_blocks_work false are, kept the
empty entity for good: getOrCreateNextSpawnData returns it, it names no
mob, and the spawner never spawns, in Horizon and in vanilla or Paper.

Horizon kept no saveable form of its structure starts, so its saves carry
an empty structures.starts and every structure it generates is invisible
to vanilla and Paper (locate, structure spawns, location predicates,
advancements) and cannot be continued past the generated area.
StructureStart::save and Piece::save write the tag vanilla writes. This
covers the pieces of jigsaw pools (villages, pillager outposts, ancient
cities, trail ruins, trial chambers, abandoned camps, bastions) with

Chunk holds the Overworld's 24 sections in every dimension, and the save
wrote them as they are: yPos -4, sections -4 to 19 and heightmaps counted
from y=-64. Vanilla and Paper trust those heightmaps, so a Horizon-made
Nether reads its surface at y=192, above the bedrock roof, and the End 64
blocks too high. Re-saving a vanilla Nether chunk rewrote its yPos too.
LevelShape (skylight, min_y, height per dimension folder) replaces the
save path's sky_light flag. yPos, the saved sections, the PostProcessing
lists and the heightmaps follow it, as SerializableChunkData.write does.
LAN clients in the Nether and End now get the chunk's heightmaps; the
heightmap check failed there and they were sent empty.

Everything the launcher fetches now goes through one HTTP proxy when there is
one: Horizon's releases and the launcher's own update, Minecraft's files and
Java from Mojang, Modrinth, CurseForge, the mod registry, pictures, Microsoft
sign-in, Tailscale's API, and the jars a modpack import downloads. It is
Settings' Proxy row (`proxy` in settings.json), or `horizon-launcher settings
proxy http://host:port`; without one, HTTPS_PROXY, HTTP_PROXY and ALL_PROXY
apply, with NO_PROXY naming the hosts to reach directly.
A local address never goes through it, and the Servers page's calls to a game
server's API stay direct: they are on loopback and asked every second.
horizon-port-pack builds its own agents, so the launcher hands it the address
(net.rs); run on its own, it reads the same variables.

Hovering a bundle showed only its name and `BundleItem.appendHoverText`'s
"Can hold a mixed stack of items": nothing drew the contents, so a player
could not see what was inside or how full it was (#2001).
`ClientBundleTooltip` is ported to `bundle::tooltip_layout`: the 96 pixel
column, the four-wide grid filled bottom-up and right-to-left from
`getNumberOfItemsToShow` (eleven stacks and a `+N` when it overflows), the
progress bar at `Mth.mulAndTruncate(weight, 94)` with the full sprite and the
`item.minecraft.bundle.empty`/`.full` labels, and an empty bundle's wrapped
description. The game draws it under the stack's own tooltip
(`Game::draw_stack_tooltip`), which the inventory, creative, container,
beacon and trading hovers now use.
Verified in game: a bundle with 64 stone shows one slot and a full red bar
labelled "Full!"; one with 32 stone and 8 dirt shows two slots (32 stone
first, as the next out) over a half-filled blue bar; an empty one shows the
description and "Empty".
🤖 Agent: Mod API render.set-minimap: a mod picks the corner, size, scale, shape and turning, and the game draws the map from the minimap extra's tiles. It is a new function, so published mods keep loading. Verified: pr_ready (1353 tests, clippy, launcher), the sandbox test, and in game beside the published mods in both modes.
🤖 Agent: Zoom moved to the mod browser. The built-in zoom is removed, and a player who had it on gets the published Zoom mod with their settings and key. Verified against the real registry, in both modes (54/54), plus clippy and the client tests.
A server's chunk columns (single player on its server thread, LAN,
servers) were decoded on the render thread: sections, palettes, biomes
and light, about 0.1 ms each on an M4 Pro. Once the backlog was overdue,
a frame decoded every waiting column at once. Now each chunk packet goes
to a decoder thread as soon as it arrives, and the frame that reaches it
in order only inserts the column. A column still decoding holds back what
follows it, overdue or not, so a frame never waits for the decoder. A
dimension or registry change since a column was decoded makes the frame
decode it again with the new format.
Forgetting a column removed its pending sections with a pass over all of
them. A moved or shrunk storage forgets thousands of columns in one frame,
so it now removes them by key and drops their block entities in one pass.

`AbstractContainerScreen` keeps `isQuickCrafting` and the drag it belongs
to on the screen. Horizon keeps both on `Game` (`inv_clicks`, `inv_drag`,
`last_inv_click`), and nothing cleared them when a screen closed: a press
whose release never reached the screen — the pointer left the window, or the
screen closed between the press and the release — left a quick-craft drag
running, and `Clicks::press` answers `None` for every later press, so clicks
went dead on every screen after it.
`Game::reset_inventory_clicks` now runs when a container closes and when the
pointer is grabbed again (the inventory's screens are behind us), which is the
lifetime vanilla gives that state.

On a server's client (single player on its server thread, LAN guests,
dedicated servers) the dragon was tracked but never built: spawn_entity
only makes mobs from mob_types(), which has no dragon, and
dragon_geometry draws Game::dragon. The crystals had their own remote
constructor; the dragon had none.
The client now keeps the server's dragon in Game:🐉
handleAddEntity builds it (full health, hovering, as its constructor
does), SetEntityData applies DATA_HEALTH_ID and DATA_PHASE,
SetEntityMotion its velocity, and its moves interpolate like other
living entities. tick_remote_dragon is the client side of
EnderDragon.aiStep: wing flaps and their sound, the growl,
checkCrystals' nearest-crystal search for the healing beam, the flight
history and the parts; a dead dragon rises and bursts as in tickDeath.
Hurt animations flash it, removal and level changes drop it, and the
player's attacks pick its parts and send the server their ids.
The in-frame fight is unchanged; its nearest-crystal search moved into
nearest_crystal_to, shared with the client.
Fixes#1530.

A pack's `sky` function gets vanilla's colour along each view ray and draws
where the vanilla sky dome draws, under the sun, moon, stars and clouds. The
pipeline's shader is the pack's checked stage (`CheckedStage::source`, new)
followed by a copy of terrain.wgsl's sky with every name prefixed
`horizon_sky_`, so none can meet a pack's; terrain.wgsl's `fs_sky` now calls
`sky_along_ray`, the same code as before.
A running pack is one `NativePack`: the frame every stage reads (written once
a frame), its sky and post stages and its pass timer. In a frame F3 times, the
sky draws in a pass of its own so the overlay can show its time; otherwise it
stays in the world's pass.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
`NativePack` holds what a running pack needs: the `frame` every stage
reads (`NativeFrame`, written once a frame before the world draws), its
post passes and the timer of its passes. `NativePost` no longer owns the
frame buffer or the timer, so the sky stage can read the same frame and
be timed by the same timer. No change in what draws.

The Mods page gets a fourth kind, Shader packs, which searches Horizon's
registry and installs a `.hshader` into `shaderpacks/` once
`index::check_file` has run the game's own `horizon_shader_api::check`.
Modrinth and CurseForge answer that tab with a pointer to the registry:
their shader packs are the shaders/ format and are not offered.
The sample index lists a shader pack (`glow`, made with
`horizon-shader new` and `pack`), so the registry build, check_file and
the launcher's install are tested on a real file. A file of the same
name the registry didn't put in place is no longer called a mod.

A mob's fluid state and its supporting block each read every cell around
its box, every tick. World::may_hold answers from the palettes of the

(large collision shapes, moving pistons) the supporting block search
reads only the cells meeting its area, as BlockCollisions' cursor does.
Results are the same.

🤖 Agent: Players rebind a mod's keys on its Options > Mods page (the game's own key rows, saved in horizon-mods.txt), with no WIT type change, so the published mods keep loading. Verified with main merged: clippy, the client, mods and SDK tests, and the in-game check in both modes (24/24).
The page lists the packs in shaderpacks/: Horizon's own, marked (Horizon) and
named by their manifest, then packs in the shaders/ format. One runs at a
time: clicking a pack picks it, clicking the picked one turns it off, and
Open Pack Folder opens the folder. The pick is saved in horizon-graphics.txt
under a new key (pickedShaderPack), so the shaderPack value older versions
saved stays ignored. A new pick drops the running pack and loads the new one
in the next frame; HORIZON_SHADER_PACK still wins, for development.

While the F3 overlay is open, the running pack's passes are timed on the GPU,
a shaders/ pack's or a native pack's, and the overlay lists the pack's total
and its costliest passes (the median of the last 15 timed frames). The timer
never waits: a timed frame's stamps are resolved once the GPU has finished it
and read back once mapped, then the next frame is timed. A native pack's first
pass counts from a mark that ends with the world's draws, so it does not carry
the time it waited for them. HORIZON_SHADER_PACK_TIMING still logs the medians.

`/loot give @s loot minecraft:chests/end_city_treasure` handed out bare gear: the
loot dispatcher in `items.rs` (the path `/loot`, bartering, raids, dispenser
tables, advancements and mob drops use) knew no `minecraft:enchant_with_levels`
or `minecraft:enchant_randomly`, so both fell through its arm untouched. Only the
chunk-generation path, which uses `horizon_world::loot`, enchanted anything —
which is why #1911 and #1437 looked fixed.
The dispatcher now runs both, as vanilla does: `EnchantWithLevelsFunction` picks
from `EnchantmentHelper.enchantItem`'s results (a book becomes one enchanted
book), `EnchantRandomlyFunction` picks one compatible enchantment at a level
between its min and max, and both resolve `options` as a tag, a list or one id,
else the whole registry. `Items` carries that registry now
(`Items::enchantments`), and `StationData` shares the same copy instead of
loading a second one.
Verified in game: six `/loot give … end_city_treasure` rolls gave 10 pieces of
gear, all 10 enchanted (unbreaking 3, mending 1 + protection 4, …), where all 10
were bare before.

Review of #1932 (rdbtCVS): with `--in-frame`, opening a world to LAN and
setting Commands Only still showed a guest's ordinary chat on the host. The
hub's `HostEvent::Chat` went through `system_message`, which asks for
`receive_system_messages` — true at Commands Only — so the line passed.
`Game::player_message` shows a chat line as `ChatSource::Player`, which is
the permission `ChatListener` checks for player chat; `lan_log_event`
routes `HostEvent::Chat` there. `/say` and `/me` arrive as chat messages
too (say_command, emote_command), so they follow the same permission as they
do for the guests' own packets; command feedback such as `/list` is a system
message and keeps the system-message permission.
Reproduced on the pre-fix build: host at Commands Only, guest sends
`baseline-visible` → the host shows `<Guest9> baseline-visible`. With this
change the same line stays hidden at Commands Only and shows at Shown.

Review of #1933 (rdbtCVS): `Game::tick` returns through `tick_remote` whenever
`remote` is set — every multiplayer session and the default single player — so
the `tick_world` call that advanced the entries never ran there. A thrown
pearl's slot stayed at full shade until the server's duration-0 packet arrived
instead of fading over the second.
`tick_remote_level` advances them now (Player.tick's ItemCooldowns.tick); the

does.

A native pack named by HORIZON_SHADER_PACK (a folder with horizon-shaders.toml

A new case in ui's widget variant stops every ui mod built before it from
loading: the runtime links a component only when each imported
function's types match exactly ("expected variant of 5 cases, found

the game lists a mod's keys first on its page in Options > Mods, as Key

🤖 Agent: ready. server_ops_feedback waits for vanilla's and Horizon's 'Saved the game' before the save step's 2 s, so a loaded runner (the desktop's full trial) no longer cuts the transcript. Harness only. verify passed; parity ran server_ops_feedback on the Mac: PASS 120 s.

Tested together with the other wave 2 contributor PRs: fmt, clippy -D warnings, and the horizon-client, horizon-world and horizon-protocol tests pass. Of the 127 harnesses the batch affects, 124 pass; the other three are a player-head mismatch fixed in #1934 and two worldgen timeouts on a loaded machine with no chunk differing. lan_e2e chat, fireball, cursor, looks, thrown, eat, shield, lava, contacts, projectiles and mobs pass with the host in-frame and on its server thread.
🤖 Agent: verified: the fix for #1772 plus #1947 merged in. Its parity job prepares with this preparer and checks that the output is still OUTPUT_VERSION 1, so with #1946 players keep their prepared resources. Merging.
Horizon had no CampfireBlockEntity, so right-clicking a campfire with raw
food did nothing. Now:
- BlockEntity::Campfire keeps four slots with their cookingProgress and
cookingTime, saved as Items, CookingTimes and CookingTotalTimes; both
campfires share the minecraft:campfire block entity type. It is not a
Container (only Clearable), so hoppers don't reach in.
- CampfireBlock.useItemOn: a campfire_cooking input goes into the first
free slot (placeFood) with its recipe's time; the use is consumed
whether or not there was room, the item is used up outside creative,
interact_with_campfire is awarded and a block_change goes out. A client
of a server leaves it to the server.
- cookTick (lit): each item's progress rises; a finished item's result
drops at the block (Containers.dropItemStack), the slot empties and a
block_change goes out. cooldownTick (unlit): progress falls by 2.
- Breaking the campfire drops its items (preRemoveSideEffects).
- The update tag (Items) reaches a server's clients, and CampfireRenderer
draws the items on the fire.

render.set-zoom divides the field of view by up to 10, eased through the

input.claim-wheel takes the wheel from the hotbar while playing: its steps

- The reach parse cache lives in the shared parity folder, keyed by content,
so a new worktree starts warm (written atomically, other worktrees'
entries kept within bounds).
- A harness's reach search stops as soon as it reaches a changed file that
differs in more than its `mod` declarations; partial searches are not
memoized. Declaration diffs are memoized (one git show per file).
- A harness whose changed dependency is outside crates/ is picked without a
search (narrowing always keeps those).
- After PARITY_REACH_BUDGET seconds (default 180) the remaining harnesses
count every source their probes link.
- crate_of is cached; no pathlib in the hot paths.
Same 79 harnesses on the 19-file diff from contrib-gate-16; CPU 19.9 s cold /

🤖 Agent: thank you kacpherek! /pregen is in, off by default: a server turns it on with horizon-pregen=true in server.properties (server.toml [properties]), single player and LAN with --pregen. With it off, the command tree and /help match vanilla. Tested on a dedicated server through horizon-server (on: 1,369 chunks generated and saved), single player on the server thread and in-frame, and 11 harnesses including command_exec.
When horizon-prepare failed, vanilla-data.sh deleted the preparation folder but kept what it had
already written to .local/ (horizon-client, horizon-client-motion, ...). The next job then saw those
real folders as already there: its preparation listed only horizon-client-structures in .entries,
and the checkout kept using the stale resources outside the per-key cache.
Now a failed preparation removes the .local/ entries it created; a job first removes real folders
named like preparation outputs, and makes again a preparation whose .entries lacks horizon-client.

They are official mods now (#1982). The Extras page loses their rows and
the HUD its built-in drawing. A player who had one on gets the mod on the
first start: installed from Horizon's registry, checked as the launcher
checks it (size, SHA-256, signature, manifest), turned on, with the
corner and options carried into the mod's storage. One chat line says so
("FPS counter moved to the mod browser: installed for you"). If it can't
be installed (offline), a line says Horizon tries again at the next
start. horizon-extras.txt keeps the old keys and lists what was done in
movedToMods.
The client's horizon-mods dependency gains the `index` feature for the
check. The frame and click counters now run only for mods.

`entity_geometry` ran `cracks()` twice per frame: once for the block-entity
pass that draws `render_breaking`, once for the overlay near the end of the
same function. Each run walked `mining` and the `destroying` map, and formatted
`block/destroy_stage_<n>` for every crack it found before looking that string up
in the atlas.
The list is computed once, at the top of the function, and the passes read it.
The ten stage names are a const table, so a crack costs one lookup and no
allocation. Nothing between the two passes touches `mining` or `destroying`,
which are only read there, so the list the second pass used to rebuild was
always identical to the first one.
No behaviour change: the same ten sprite names, and a stage above 9 still finds
no sprite and skips the crack.

Atlas patches rasterized while building world text (display text, name
tags, sign glyphs, map items) drained into the HUD batch before
entity_geometry ran, uploading a frame late: for that frame the quads
sampled unwritten atlas cells, so text flickered or showed the wrong
glyphs whenever content changed or new text entered view.
Display text also lined up 10 px apart where vanilla's lineHeight is 9,
its background quad stopped a pixel short of vanilla's -1..width+1 fill,
and name tags used 0x7F where renderNameTag's colours are 0x20FFFFFF
(discrete) and 0x80FFFFFF (see-through). lightCoordsWithEmission floors
only the block channel at 2 and leaves the sky alone, and a discrete
name's background draws lit in the normal pass rather than unlit.

The clean checkout removes target/, and vanilla-data.sh builds horizon-prepare only when it
prepares afresh, so compile-exporters had no binary on a cached preparation. The bundle is
also compiled in the job instead of reused from .local/exporters, which vanilla-data.sh links
to preparations that pull requests' parity jobs write, and the job fails if anything but our

The previous commit decides chunks far from the rings without them. The

ATLauncher saves Mojang's version JSON as is in configs/json/minecraft and

folder chosen, ATLauncher's default folder on each system after the
official launcher's, then the CurseForge app's Install folder. The lock's
pins gate it as before, and nothing is downloaded. The error names every

The camera's death roll and zoom (GameRenderer.bobHurt, Camera.modifyFovBasedOnDeathOrFluid) read deathTime + partialTick. Horizon derived deathTime from the wall clock since the death message, which the server thread path never set: there deathTime stayed 0, so every frame used 0 + partialTick and the view rolled from 0 to 0.2 degrees and snapped back twenty times a second (with a matching zoom pulse) instead of settling at vanilla's 3.6 degrees. In frame, the wall-clock ticks were not in step with the frame's partial tick either.
deathTime is now the tick counter LivingEntity.tickDeath keeps: the in-frame tick already counted it, and the server thread path now resets it when the death screen opens and counts it once per client tick. horizon-ctl state reports it as player.death_time.
A server player's clicks in a furnace, brewing stand or crafter menu wrote
the block entity's slots but never marked it changed, so the chunk was
not saved: an idle furnace (nothing burning, so its own tick changes
nothing) given or emptied through its menu rolled back on reopen or
chunk unload, losing or duplicating the items. Comparators kept the old
reading too.
When the click changed the container's slots, call container_changed
(BlockEntity.setChanged, reached through Slot.setChanged in vanilla's
AbstractContainerMenu.doClick and quickMoveStack), as chest-like menus
already do.
A server's player on a trip into another level was skipped by
tick_guests before its zero-health body was marked dead, so a death
during the arrival (a /kill, damage) only counted once the destination
had loaded. The client already showed the death screen, and a Respawn
press in between was refused (guest_respawn wants a dead player) and
then lost, leaving the player on the death screen until a second press.
LivingEntity.hurt calls die at once, loaded or not: the death half of
the guest tick is now its own guest_die, which also runs for a player
on a trip.
Servers on 26.3 spawn NPCs as minecraft:mannequin — the avatar entity
vanilla added for exactly this — instead of fake players (gommehd.net's
"Gommunity" lobby NPCs are invisible today). The client never registered
the type: MobTypes.load only builds species::ALL, so AddEntity produced a
tracked entity but nothing to draw.
- EntityDataSerializers.RESOLVABLE_PROFILE (41) decodes into
Value::Profile. Before, the entry list ended at it and the mannequin's
DATA_IMMOVABLE and DATA_DESCRIPTION after it never decoded.
- species::ALL gains mannequin (player#main model, Humanoid anim), and
the player-only render paths — skin texture, sleep pose,
AvatarRenderer's 0.9375 scale — take an avatar() check instead of the
id string.
- SetEntityData's apply stores DATA_PROFILE on the mob, and
update_remote_skins resolves its textures property through
PlayerSkinRenderCache's rules (unsigned allowed, SkinManager's
insecure path) the way a tab player's skin resolves.
- Mannequins get the shared-flags crouch and sleeping-position handling
other players already had.

A player sprint-swimming up under a ceiling was sent back every tick on the server thread (and for LAN guests): the server never updated the player's pose, and handlePlayerPositionChange's collision check always used a standing 1.8-block box, so the 0.6-block swimming box the client moved with looked like it entered the ceiling. Player.tick ends with updatePlayerPose, and the check uses getBoundingBox, so run updatePlayerPose in the server player's tick and check moves with the pose's dimensions. Fixes#1899.
A used End gateway never worked again on the server thread or on a
dedicated server. TheEndGatewayBlockEntity's server ticker (portalTick)
ran only inside the client block-entity pass, which returns at once when
there is no renderer, so the 40 tick cooldown that
EndGatewayBlock.entityInside starts (triggerCooldown) never ran out.
A Game without a renderer now runs portalTick on the gateways it keeps a
server copy of, in block-ticking chunks as Level.tickBlockEntities does,
and sends triggerCooldown's block event every 2400 ticks of age.
A server's player sent into another level waits on a trip until the
chunks around its target load, and the server leaves its body alone and
skips its portal checks until then. A /tp within the level while the
arrival was still loading left that trip behind: its target lost its
loading tickets and never finished, so Nether, End and gateway portals
stopped taking the player until they went back to the abandoned spot.
ServerPlayer.teleport within a level places the player at once, so the
pending arrival is now abandoned. server-dimension-players gains the
case: sent far into the Nether, teleported back near the origin before
the far chunks load, then an End portal there.
The chat keeps where each message came from and the Chat option's
abilities. A message the option hides is still dropped on arrival, but a
change of the option now also hides the lines already in the chat that
it no longer shows, and brings them back when it shows them again
(ChatComponent.setVisibleMessageFilter -> refreshTrimmedMessages), on
apply_settings. Every Chat::add names its source. The Restrictions
screen reads its two flags from ChatAbilities instead of its own copy.

A chest minecart, hopper minecart or chest boat's menu edits a stand-in
container, which is meant to be copied back to the vehicle when the menu
closes. close_container took the open container before calling
close_cart_container, which then found nothing open and copied nothing:
items taken out came back on the next open, and items put in vanished.
Copy the stand-in back from the key close_container took. A server
player's clicks in such a menu copy it back at once, since the menu is
the vehicle's own inventory (ContainerEntity, AbstractMinecartContainer
and ChestBoat implement the container the menu reads and writes).
FireworkRocketEntity.dealExplosionDamage hurts every LivingEntity within 5
blocks that the rocket can see (its feet or its middle, ClipContext
COLLIDER with no fluids), besides the entity it is attached to. Horizon only
hurt the attached player and the nearby mobs, so a rocket bursting next to a
player on foot did nothing to them, in both single player modes.
The player (unless it is the attached one) and every guest in the level now
take damageAmount * sqrt((5 - distanceTo) / 5) as fireworks damage, with the
armor wear of hurtServer. distanceTo is a float, as vanilla computes it, for
the mobs too.
Vanilla has no /pregen, so with it always registered /help and the command
tree differed from vanilla's (the command_exec harness failed on /help).
Horizon's own commands are now added to the game's tree only when the owner
asks: `horizon-pregen=true` in server.properties (`horizon-pregen = true`
under [properties] in server.toml) for a dedicated server, `--pregen` for
the game (single player, LAN). Off, the trees are vanilla's own, unchanged.

A mob that sees a guest (a LAN guest, or the player of the server thread)
holds Who::Player as its target, and what it does to that player runs with
the guest swapped in. A shulker's bullet, though, keeps the target it was
fired with until it lands, and the projectiles tick outside that swap:
there Who::Player is the host's own player, so on a server thread the
bullet found no target, stopped homing and fell onto the blocks.
The bullet now carries the guest's entity id, as ShulkerBullet.finalTarget
holds the targeted entity in vanilla (ShulkerAttackGoal.tick passes
Shulker.getTarget()), so it homes on the guest among the projectiles'
targets and its hit runs as that guest: 4 damage and Levitation.
The FPS counter and keystrokes extras rewritten as mods on the public API
(render, input, ui, storage), in mods/official/, with the extras' options
on their settings pages and the extras' look: the same boxes, colours and

pr_ready cover them; a maintainer publishes them in horizon-mods. The
built-in extras stay until the removal PR, which installs these for the
players who had them on.

Clicking with a torch or flower into a space that is already taken (or where the block cannot stand) made the server-thread client play the block's place sound when the server resent the refused target. BlockItem.place returns FAIL before playSound when canPlace() is false, and the client only hears its own predicted placement, so clear the pending place sound when no placement was predicted.
- Skull keeps what its profile draws (the skin URL, its skins/<sha1>
sprite and the default skin), computed when the block entity loads,
instead of decoding base64 JSON and hashing it for every head every
frame; skull_skin_at no longer scans the chunk's saved block entities.
- BlockEntity::for_block gave minecraft:piston_head a skull block entity
(it ends in _head), which would have been saved as minecraft:skull.
- AGENTS.md is left as it is on main: the workflow note is not part of

The built-in extras become official mods; these are the calls the FPS
counter and keystrokes overlay need to look and behave the same:
- render.set-corner(corner, w, h, shapes): a box the game places with
its own corner stacking (under the status effects, with the overlays
and hud panels), clear-corner; text-width(text) in the HUD font
(advances for U+0000..U+024F, 6 otherwise); frame-stats(): the game's
FPS counter (fps, min, 1% low).
- input.mapping(name): a movement or click mapping's key label and
whether it is held; clicks-per-second() for attack and use.
- ui: a button widget (200 x 20, select(id, 0)) for settings pages.
- The game keeps its FPS and click counters running while a mod runs,
and refreshes the snapshot every frame for mods with a frame hook.
- The ui test guest gains /corner and /readings, with a sandbox test.

The particle engine copied the GUI atlas's sprite rects once at start; a pack or server-pack
change rebuilt the atlas but not the engine, so every named and set sprite then drew a stale
region — break crumbs showed other blocks and campfire smoke showed random items (#1923).
The engine now re-reads the rects and the packs' sprite sets on reload, and a particle whose
sprite-set index outlived the rebuild keeps its sprite instead of indexing past the new list.
The reload also layers content mods over the root again, which startup does but reload forgot,
so the first reload silently dropped their assets and data.

Both lists drew a scroll bar but only listened to the mouse wheel: a press

`ui::Scroll` already models AbstractSelectionList's press/drag/release (the

- WIT `input`: claim-items(ids) makes the use button on those items the

The snapshot's key hashes the 70 MB of source tables it was resolved from.
The client's tables and the world generator's are loaded from the same
folder, so a world opening hashed them a second time: a third of a second

hash is now kept for the process, by each file's length and modification

The 128 stronghold biome searches (two seconds of CPU on a 4-thread laptop)
ran when the first chunk of a new world looked up its structure starts, so
nothing near spawn was generated until they were done. Each search ends
within 8 chunks of its ring chunk, which is known before searching, and
strongholds lie 1,400 blocks out or more: a chunk with no ring search in
reach (exclusion zones included) is now decided without them, which is what
they would say. They run when a chunk near a ring, /locate or an eye of
ender needs them (ring_positions now searches on demand instead of returning
nothing before a lookup did).

Nothing tracked `ItemCooldowns`: `draw_item_decorations` passed a cooldown of

`horizon_client::cooldowns` keeps the `use_cooldown` component's entries by
cooldown group the way `Player.getCooldowns` does (start and end ticks, the
percent `getCooldownPercent` returns), `ItemInfo` now carries the item's
`use_cooldown`, and the game uses it where vanilla does:
`ServerPlayerGameMode.useItem`/useItemOn refuse a stack on cooldown,
`ItemStack.applyAfterUseComponentSideEffects` starts the entry when a use
finishes (a thrown pearl, a wind charge, an eaten chorus fruit),
`GuiGraphicsExtractor.itemCooldown` shades the slot, and a server's guests
keep their own and are sent `ClientboundCooldownPacket` (started, and 0 when

Mods draw through the game's own renderer, never their own shaders:
- WIT `render`: set-hud(shapes) with fill, quad (any four corners),

- Drawn over the HUD after the extras, under chat and screens, hidden
with F1 (game/mod_render.rs). Colours are 0xAARRGGBB.
- shake turns the view, not the player: jolts fade out squared, add up
to 1, at most 3 degrees of yaw and 2 of pitch, scaled by Distortion
Effects (screenEffectScale; 0 turns it off).
- Experimental: the manifest needs experimental = ["render"].
- No mod drawing, no cost: an empty iterator and an is_empty check.
- cargo horizon-mod check reports shakes and HUD shapes. The ui test

Review on #1864: when a mod stops while its screen or settings page is
up, draw_mod_screen dropped the player back to Playing without
capture(true), leaving the mouse free until the next click into the
world. The dead surface now leaves through close_mod_screen, which puts
back the screen it covered and holds the mouse on a return to Playing;
the same goes for a screen dropped while it was up.
mod_ui_view also cloned the title and every widget (up to 64, lists to
512 rows) on each frame, click and scroll. It now borrows the mod's
stored widgets — the screen's scrolls live in a disjoint field — and the
click finds the picked row first so the &mut ui_select runs after.

The game that simulates a world now starts its server mods (API 0.3,
experimental): single player's server thread, single player in-frame
(beside client mods), a LAN host either way, and the dedicated server.
Windows that are clients of a server never run them.
game/server_mods.rs: tick_server_mods at the end of the tick diffs the
players (player_joined, player_left), delivers the tick's chat and block
events in order, then calls tick. Block events come from players' breaking
and placing (the acting player is the guest during as_guest); chat from the
local chat path and the hub's new HostEvent::PlayerChat; a guest's /command
reaches its mod before vanilla's dispatcher. tell and command replies go to
their player (the window's chat or a SystemChat); broadcast goes to every
player and the log.
--dev-mod now works on the server thread, and servers check a dev mod's
file once a second from their tick. Every hook returns at once when no
server mod runs; without the mods feature they are empty stubs.

The shadow program now draws the world's terrain from the light's view.
The shadow pass culls its own section list against the shadow camera's
frustum (render distance, capped by shadowDistanceRenderMul), nearest
the light first, and draws only the faces toward the light. Its draws go
by arena page within 64-block bands from the light, as the camera's solid
draws do, so the flat path draws them in about ten calls per list instead
of one per page change (over a thousand with BSL). Its draws
follow the camera's translucent draws in the same instance and indirect
buffers, so the flat path gives them calls of their own. Sections never
sorted for the camera are sorted once so their translucent indices are
valid.
The frame's first shadow pass clears the shadow map and shadowcolor
buffers as it begins, instead of a separate pass that loads and stores
them all; the translucent shadow pass is timed under its own label.
Without a pack nothing changes: the shadow lists are empty and the
terrain stays one draw call.

check that every chunk of squares and circles is swept once and that
the largest radius plans at once.

Launchers like HMCL rewrite versions/<v>/<v>.json in the official layout
(same jars and libraries, their own fields), and horizon-prepare refused it
as a version Mojang may have republished. Mojang's copy saved as the imported
manifest.json is now used instead, and without one the error says the
launcher may have rewritten it and how to get Mojang's.

The `shader` kind's check (index::inspect) reads the .hshader and runs
horizon_shader_api::check, the same check the game runs before it loads a
pack, so the registry's CI (`cargo horizon-mod check` / `registry build`)
refuses a pack the game would refuse, with each problem at its file and line.
Its facts are the manifest's id, version and shader API line. The kind's
files are .hshader, `cargo horizon-mod check` recognises them, and
registry::open takes shader submissions. Installing one from the launcher
stays refused (check_file) until the launcher installs shader packs.

When the shadow pass runs, the pack gets real shadow buffers (spec 6.3):
shadowtex0 (cleared to 1.0 every frame), shadowtex1 (a copy, made only when
a program reads it) and shadowcolor0/1 (each with two sides, made only when
used, cleared to their ShadowClear colour, white by default), square at
shadowMapResolution within the device's limit.
Samplers: shadowtex0/watershadow, shadowtex1, `shadow` (shadowtex1 beside
watershadow) and the HW forms read the shadow map, through a linear depth
comparison when declared sampler2DShadow; shadowcolor/shadowcolor0/1 read
the colour buffers. In the shadow programs, buffer n is shadowcolor n and
colortex reads a stand-in. Without the shadow pass nothing changes: the
names read the stand-ins as before.
shadowcomp..shadowcomp99 run after the shadow pass and before prepare, each
drawing into the alt side of the shadowcolor buffers it writes and flipping
them after, as composite programs do with colortex (6.1.6). The shadow pass
itself draws nothing yet, so the map stays clear.

The shadow pass runs when some program reads a shadow buffer (shadow,
watershadow, shadowtex0/1, their HW forms, shadowcolor, shadowcolor0/1) or
shadow.enabled=true; shadow.enabled=false keeps it off (spec 2.5). Then
`shadow` (solid and cutout terrain), `shadow_water` falling back to
`shadow` (translucent terrain) and shadowcomp..shadowcomp99 load, in the
new Shadow and ShadowComp groups (2.1, 2.4). shadow_solid and shadow_cutout
are not used: the game's solid and cutout terrain is one draw.
Their output n writes shadowcolor n (6.3): draw buffer lists stop at the
first index past 1. translate_shadow gives a shadow program the shadow
camera's matrices as its model-view and projection (5.2). The game does not
draw any of them yet.

The stage files' shadow constants (shadowMapResolution, shadowDistance,
shadowDistanceRenderMul, shadowIntervalSize, sunPathRotation, shadowMapFov,
shadowNearPlane, shadowFarPlane, shadowHardwareFiltering[0|1] and the
shadowcolor0/1 Format, Clear and ClearColor) are read into Config::shadow
(spec 6.3, 7.1).
The shadow matrices are no longer a placeholder (OQ-6): the camera looks
from the shadow light, sits 128 blocks toward it from a point that moves in
steps of shadowIntervalSize along the shadow view's own axes, and projects
orthographically over shadowDistance each side (or in perspective with
shadowMapFov), between shadowNearPlane and shadowFarPlane.
sunPathRotation turns the sun and moon's path about the world's X axis:
sunPosition, moonPosition, shadowLightPosition and the shadow camera follow
it, and so do the sun, moon and stars a pack's gbuffers_skytextured and
gbuffers_skybasic draw.

A test script drives a server mod as a server would: join = "Alex" brings a
player in (ids stable per name, so a rejoin is the same player), as = "Steve"
picks who acts (the first player on otherwise), and player, chat, command,
break and place are that player's doing; leave = "Alex" lets them go. Server
expectations: told (every players.tell, "Name: text") and broadcast; feedback
and error read the reply to the player who typed the command. Ticks call both
kinds of tick hooks, so one script format serves client and server mods.
The welcome example gets two scripts (greeting, a newcomer announced once
even after a reload, /online across dimensions, /mined per player), run by
the sandbox tests with coords-hud's; docs/mods.md lists the server keys.

A server mod runs where the world is simulated. Its manifest says side =
"server" and api = "0.3" (only a server mod may), and its component targets
the new WIT world horizon-server-mod:
- imports log and storage as client mods do, and the new capability players:
online() (id, name, position, dimension, game mode, health), tell(id, text),
broadcast(text), 8 lines per call shared with chat;
- exports server-events: init, tick, player-joined, player-left, chat, command
(with the player who typed it; its feedback goes back to that player),
block-broken and block-placed (with the block state as text).
horizon-mods: a second bindgen world sharing log and storage with the first;
a running mod holds either kind of hooks; Mods::load_for(Runs) starts only the
mods a game runs (the window client mods, the world's server server mods,
in-frame single player both) and marks the others Elsewhere. Client and server
commands are owned separately. The game passes Runs::Client for now, so
nothing changes in game until its server code calls these hooks.
The SDK gains horizon_mod_sdk::server (ServerMod, Registration,
export_server_mod!), the example server mod welcome (greets, announces
newcomers kept in storage, /online, /mined), and cargo horizon-mod check's
trial run plays a server mod with a player joining, chatting, typing its
commands and leaving. The manifest refuses client capabilities on a server
mod and players on a client mod. The generated reference, the guide, the
portal and the stability table describe it.

ServerLevel.globalLevelEvent (an end portal opening, 1038; the dragon's
death roar, 1028) went to the Game's own audio without a position, which
is never forwarded: on the server thread, LAN and dedicated servers
nobody heard them. They now go to every guest as a global LevelEvent,
which a client plays two blocks from its camera towards the event
(LevelEventHandler.globalLevelEvent).
ClientPacketListener.handleExplosion plays the packet's explosionSound;
the client always played entity.generic.explode (a vanilla server's wind
charge sounded like TNT).

PlayerInput was rewriting the server sprint flag from the Ctrl and forward
keys. That flag is synced back onto the client, and jumpFromGround adds its
0.2 look-direction impulse only while the flag is set, so releasing Ctrl
before the jump (or double-tapping forward) produced a plain hop. Sprint
still starts and stops through PlayerCommand.

A mod's tests/<name>.toml scripts run in the sandbox the game uses, with no game
and no window. The runner plays the game's part (the player and clock the mod
reads, ticks, frames, chat lines, commands, a reload) and each step checks what
the mod did: its commands, chat lines, command feedback and errors, HUD panel
and corner, or that it was turned off. A failing step names itself and prints
expected against got. Each script runs on a scratch copy, so storage starts
empty and is removed afterwards.
horizon_mods::testing (feature runtime) holds TestGame and Script; the cargo
subcommand builds the mod (or takes --hmod), filters scripts by name, and fails
when one does. The template gains tests/hello.toml, coords-hud gains panel and
where scripts, and the sandbox tests run the example's scripts and check the
runner's failures, reload and expected stops. Scripts don't care what language
the mod is written in, so script mods (Lua) get the same runner.

TrappedChestBlock.getSignal is the chest's opener count (at most 15);
TrappedChestBlockEntity.signalOpenCount updates the blocks around it and

NetherPortalBlock.entityInside runs on the client's own level too: its

MotionEvent::InsidePortal, so single player on the server thread, LAN
guests and dedicated servers' players went through portals without it.

When the band hasn't moved for 30 seconds the task logs how many chunks
of its first row are not loaded, being lit, unlit with no light job or
not post-processed, with the streaming stage counts, and queues light
again for unlit chunks whose neighbours are all loaded.
pause-when-empty-seconds paused a server with nobody online after a
minute, and a paused server skips its tick: post-processing stopped, so
the band waited forever on a row of lit chunks. A running /pregen now
counts as activity; the countdown starts once it is done.
A Chunky-like command for single player and servers: /pregen start
<radius> [square|circle] [<x> <z>], status, pause, continue and cancel,
with progress (chunks, chunks/s, time left) in the log and to the player
who started it.
The area is swept strip by strip by a band of rows that streaming treats
like a player's area (Streaming::set_band). A row is done once its chunks
are lit and post-processed; the rows behind the band then unload and are
saved, so memory holds only the rows in flight. The band's chunks are
ranked for decoration row by row as they come within reach, so a task
decorates in the same order however its jobs are timed. Between ticks
the server waits on the workers' results and schedules the next jobs at
once instead of once a tick.

A pack with gbuffers_hand (or textured_lit, textured, basic; spec 2.3)
draws the first-person hand and held items after the opaque world, into
its own buffers and the world's depth, without blending and with the
entities' 0.1 alpha cut. The vertices are Horizon's hand geometry, read
as entities are; `gl_ProjectionMatrix` is the hand's own projection (the
hand's field of view and bob) with depth scaled by MC_HAND_DEPTH, while
`gbufferProjection` stays the world's (5.2). Horizon's own hand draw is
skipped only when the pack draws it.

`item.properties` (spec 4.1) gives `heldItemId` and `heldItemId2` the

empty hand, 0 without the file (5.3). `heldBlockLightValue(2)` are the
light levels of the held items' blocks, as Horizon's dynamic lights
already compute them. With `oldHandLight` (on unless the pack turns it
off, OQ-21) the first id and light are those of the brighter hand.

A pack with gbuffers_weather (or its fallbacks textured_lit, textured,
basic; spec 2.3) draws the game's rain and snow after translucent
terrain, blended, with vanilla's 0.1 alpha cut. The weather quads become
entity vertices with their UV animation applied on the CPU (the same
phase Horizon's weather shader computes; a test checks it against the
weather columns bit for bit), and rain and snow each read a copy of
their sprite, so the pack's `texture` repeats down the column as a
standalone texture would. The shared atlas gains COPY_SRC for that copy.
Without a pack nothing changes: Horizon's weather draw is skipped only
when the pack draws it.

A pack with gbuffers_clouds draws Horizon's cloud geometry itself (spec
2.3, OQ-3: no fallback), blended, after the opaque world. Horizon's own
cloud draw is skipped then, also when the pack's program writes nothing
(BSL and Complementary hide vanilla clouds that way). Without a pack the
cloud draw is unchanged.
The translator now rewrites a bare `discard;` or `return;` to
`if (true) discard;` / `if (true) return;`, so code a pack leaves after
it stays reachable for naga ("Expression not visited"). This also fixes
Complementary Unbound's gbuffers_skytextured.

From spec-yungsapi rev 3 §3, §3.1 and §3.2 (impl-questions IQ-2, IQ-3):
- the start piece does not count toward max_count;
- is_priority entries are tried first, in the pool's shuffled order, without
a weighted draw; min_required_depth skips a pick (no draw) while the parent
piece is shallower; ignore_bounds places without the free-space test (its
box is still taken, IQ-12);
- the fallback was already shuffled only when reached.
The port no longer counts these three fields as lost. The layout harness gets
yung-probe and yung-probe2: the spec team's probe pack (built from the oracle
profile) carried as a mod, compared start by start with the oracle's census:
384 of 384 and 32 of 32 starts match.

A shader pack now draws particles with `gbuffers_particles` (falling
back to `gbuffers_textured_lit`, `gbuffers_textured`, `gbuffers_basic`)
and the entity parts that blend, a sneaking player's faded name tag and
entity shadows, with `gbuffers_entities_translucent` (falling back to
`gbuffers_entities`). Both blend with the translucent default unless
`blend.*` says otherwise; particles keep vanilla's alpha cut at 0.1.
Name tag text draws with `gbuffers_entities`, as cutout (2.3).
Particles draw after deferred, with translucent terrain, unless
`particles.ordering=before` or `particles.before.deferred=true`;
translucent entities draw before deferred unless
`separateEntityDraws=true` (3.2).
Without a shader pack nothing changes.

A shader pack now draws entities with `gbuffers_entities` and block
entities with `gbuffers_block` (or their fallbacks, spec 2.3), after
terrain. Each run of the entity spans is one draw with its own
`entityId` or `blockEntityId` and `entityColor` (the hurt red, the
white flashes) in a per-draw slot. Horizon still draws everything else
(particles, cracks, beams, name tags, shadows, End portals, clouds) in
its own single entity draw, without the runs the pack drew.
The entity vertices are read again at set 1, so the pack gets the face
normal where a vertex has none (block entities), `at_tangent` along the
texture's u and `mc_midTexCoord`, as for terrain.
Entities and block entities draw without blending, with the loader's
alpha test at GREATER 0.1, as cutout (OQ-23); name tags and shadows,
which blend, stay Horizon's for now.
`HORIZON_SHADER_PACK_TIMING` no longer panics when a pass skips a whole
report window (no entities in view).
Without a shader pack nothing changes: the split only runs while a pack
draws entities.

Gbuffers programs get the loader's alpha test on output 0 when they

far; `alphaTest.<program>` replaces it for that program (`off`, or a GL

The previous tests of litho.rs are deleted unread (clean-room ruling of
2026-10-25). The new ones build their own block registry from a facts
table and run each processor through process_list against a one-block
world: block_swap's property copy (CTOV's beetroots), references in

apply_random per piece and per block, set_block's providers and its
block entity modifier.

The mod world now takes each saved start whose pieces are all jigsaw pieces
as the oracle saved it (chunk_dump's HORIZON_SAVED_STARTS, through a new
GeneratorWorker::use_saved_start and PoolPiece::from_saved), so the blocks
are checked whatever the layout: Lithostitched lays jigsaws out its own way
(spec-lithostitched OPEN-L5) and the layout harness checks layouts apart.
Lithostitched's wrapper elements place their delegate; 1.21.1 block states
are read in 26.3's shape.
Counts are split between positions inside a piece's box and around them
(terrain adaptation, decoration), and every mismatch class is written to
.local/structure-layout/<profile>/blocks-report.json.
A CTOV profile carries Lithostitched and ChoiceTheorem's Overhauled Village
from a pack's jar folder (.local/structure-oracle/pack-jars).

Clean-room implementation from spec-lithostitched.md §3-§5 and spec-ctov.md §4.
The game reads Lithostitched's processors as its data writes them
(processor/litho.rs): block_swap (only the properties the new block can
have: ripe wheat becomes ripe carrots, beetroot keeps its default age),
reference, apply_random, condition (with else, one processor or a list),
set_block (simple and weighted providers, preserve_state, block entity
modifier) and discard_input; the conditions all_of, any_of, not,
random_chance, true and matching_blocks (input or location, properties).
Their random follows random_mode per block or per piece; Lithostitched's own
seeding is open (OPEN-L6), so a positional random of the world seed and the
processor stands in (impl-questions IQ-7).
horizon-port-pack's new lithostitched module carries the processors as they
are, with the processors nested in them carried, drops those the game cannot
read (lists named by tag, other providers) as Java processors, turns CTOV's
modular_compat into a reference when its mod is ported along (else nothing),
maps lithostitched:jigsaw to vanilla's jigsaw (vanilla layouts, the decision
on OPEN-L5), unwraps limited/guaranteed/delegating elements to their
delegate (limits counted as lost until the next PR) and writes
add_template_pool_elements modifiers as horizon:add_to pools when their
NeoForge load conditions pass.

The clean-room structure oracle saved, for each start of a mod world, the
blocks of its box and every position around it that differs from the no-mod
world of the same seed. tools/test_structure_blocks_parity.py generates the
same chunks in full with Horizon twice (26.3 alone, and with the mods carried
by horizon-port-pack as players' packs are) and compares: a position counts
only where Horizon's no-mod world equals the oracle's (1.21.1 and 26.3 differ
elsewhere), and a mismatch is reported by its no-mod, expected and Horizon
blocks, so a missing processor rule reads as one line.

Three things kept Sildurs Vibrant black or wrong:
- Matrix and array varyings (`varying mat3 tbnMatrix;`): wgpu's stage
interfaces take only scalars and vectors, so the translator now carries
each column or element as its own varying and copies them out of and
into a private global around the pack's `main`.
- Switch options defined in an included file whose name is not a shader
extension (`#include "shaders.settings"`) were not read, so every
`program.<name>.enabled` that tested them was false and the composites
were skipped (OQ-13).
- `fogStart`/`fogEnd` mixed the start of one of vanilla's two fogs with
the end of the other, so on clear days fog began at the camera and
Sildurs' water turned white. They now come as the pair of the fog that
is complete nearer (OQ-36).

A program sampled every level of a buffer that has mipmaps, even after a
later program had rewritten the buffer: the levels below the first were
stale. Complementary's FXAA, which samples its colour buffer with implicit
derivatives inside branches, picked those levels at edges and drew black
dots along every edge. A buffer now binds its whole chain only while the
chain matches its content, and its first level otherwise (6.1.7).

Custom uniform expressions and programs now see the biome at the camera:
`biome`, `biome_category`, `biome_precipitation`, `temperature` and
`rainfall`, and the `BIOME_*`, `CAT_*` and `PPT_*` constants (spec 3.4).
Before, `biome` and every `BIOME_*` read 0, so a test such as
`biome == BIOME_PALE_GARDEN` held everywhere: Complementary drew the pale
garden's fog over every world, and BSL treated every biome as cold, dry,
swampy and so on at once.
OQ-11: `biome` is the index in the game's biome registry (vanilla's
biomes sorted by identifier); names from before the 1.18 renames map to
their successors; a `BIOME_` name that matches no biome reads -1.

Flat terrain's vertex stage reads its quad's first three corners from the
arena page (bound per page at set 3, beside mc_Entity's table) and gives
gl_Normal / vaNormal the face normal and at_tangent the tangent along
the texture's u, with w the handedness of bitangent = cross(tangent,
normal) (spec 5.1). The pack's terrain and water pipelines cull back
faces as the game's own terrain does (clockwise front faces, rows being
flipped to GL's): water's surface no longer shows its downward copy.
Flat draws call a hook per arena page (Flat::draw_with); the arena lists

block.properties (spec 4.1) is read: `block.<id>=` names with optional
namespaces and state filters; the most specific matching entry wins.
Terrain vertices carry their sprite layer, not their block, so the game
builds a table of the block sprite layers: each takes the id of the block
named like its sprite, else the id most blocks drawing it share; y is 1
on the water and lava sprites. Flat terrain reads it from a storage
buffer at set 3; other draws and packs without the file read (-1, -1).
Building the table takes 14 ms for BSL, 39 ms for Complementary.

A dialog's text inputs are edit boxes (labelled above, CommonLayouts.
labeledElement; width, max length and initial value from the dialog) and
its boolean inputs are checkboxes with their label. A click focuses a box
or toggles a box, Tab and Shift+Tab move between the text inputs, the

fills the command templates and custom actions' payloads.
With this, AuthMe's register and login dialogs work: players type their

horizon-ctl's `type` types into the focused input of an open dialog (the

gbuffers_skytextured (or gbuffers_textured, gbuffers_basic) draws the

the shared atlas their sprites live in. The sky's parts draw in vanilla's
order (disc, sunset, sun, moon, stars, void), in one render pass while
consecutive programs write the same buffers. The sun and moon add to the
sky (SRC_ALPHA, ONE) unless blend.<program> says otherwise. Horizon's
world pass skips its own sun and moon when the pack draws them; a part
without a program stays Horizon's.

The pack's gbuffers_skybasic (or gbuffers_basic) draws vanilla's sky
geometry, as Horizon's own sky builds it: the disc at y 16, the sunset
fan while the sun is low, the stars and the void disc, each with its
render stage. One static vertex buffer; the frame's colours and rotations
sit in a small uniform the vertex inputs read. The sky draws after the
world copy and before terrain, at the far plane: only where nothing else
drew, without writing depth. It blends with the translucent default unless
blend.<program> says otherwise. Horizon's world pass then skips its own
sky disc, stars and void. The sun and moon stay Horizon's for now

A server's open_screen title is a text component, and container screens
draw it as AbstractContainerScreen does: in the label grey, under the
component's own colours, bold, italics and fonts, with the § codes a
literal holds. Horizon flattened it to a plain string, so a plugin's
gold and bold "Server Selector" menu showed in plain grey (#1645).
Chests, hoppers, dispensers, droppers, brewing stands and the other
workstations now draw the server's title. Before, the workstations
ignored it and showed their default name.
horizon-ctl's `screen` reports the title span by span (text, colour,
bold, italic). server_e2e's new `titles` check names a chest on the
vanilla server with a styled CustomName, opens it, and checks the title.

A server's show_dialog (configuration and play) opens vanilla's
DialogScreen instead of being dropped: the header with the title and the
warning button, the message bodies in a scrolling column, the action
buttons packed into columns (MultiButtonDialogScreen) or side by side in
the footer (notice, confirmation). A button runs its click event: a
custom action goes back as custom_click_action, a command runs (in play;
in configuration vanilla only warns), show_dialog opens another dialog,
copy_to_clipboard copies. after_action closes the screen, leaves it, or
opens the WaitingForResponseScreen. The warning button opens the
"custom screen" warning, whose Disconnect leaves the server. clear_dialog
closes it, and so do the level loading screen and a disconnect. The world
and HUD blur behind it as behind any in-game screen.
Inputs come next; here they are not drawn and keep their initial values.
tools/server_e2e.py is a new harness: a vanilla 26.3 dedicated server and
one Horizon client. Its dialog check shows a dialog with /dialog show,
clicks a command button (the server's trigger), a custom action (the
server's debug log shows its payload) and a wait_for_response one, and
clears a dialog with /dialog clear.

A gbuffers program's renderStage, entityId, blockEntityId and entityColor
(spec 5.3, updated per draw) move to a block of their own at set 2 that
the game picks per draw with a dynamic offset: one slot per render stage.
Terrain draws as TERRAIN_SOLID, translucent terrain as
TERRAIN_TRANSLUCENT. The terrain test pack paints any other stage red.

`const bool <buffer>MipmapEnabled = true;` in a deferred, composite or
final program's fragment stage now regenerates that buffer's mip chain
right before the program (6.1.7), on the side programs read, and only
when the buffer changed since its last chain this frame. Each level is
the average of the 2x2 texels above it; levels attach one at a time and
programs sample all of them. Unfilterable buffers (integer, 32-bit
float) get none, with a note.
BSL's bloom read every tap from the full-size buffer before; with its
chain composite4 drops from 0.38 to 0.29 ms at 720p on the Mac mini
(HORIZON_SHADER_PACK_TIMING, the chains included), and blurs as intended.

show_dialog and clear_dialog in configuration and play, and
custom_click_action, the answer, in both. Dialog.DIRECT_CODEC as
horizon_client::dialog: the five dialog types, their bodies, inputs and
actions with vanilla's defaults, the values inputs hold, and
Action.createAction (a command template's $(key) substitution with
escapeWithoutQuotes, a custom action's payload of every input's tag).
Nothing uses them yet: the screen comes next.

HORIZON_SHADER_PACK_TIMING=1 puts timestamps around every pass of a
shader pack, one frame in 30, and logs each pass's median every 30
timed frames. The frame after a timed one waits for the GPU before
reading them (Metal resolves timestamps without waiting for the passes
that write them). Passes overlap on tiled GPUs, so a pass is charged
from the later of its beginning and the previous pass's end.
This is what attributes a pack's cost to its own programs or to ours
when the machine is shared and FPS comparisons are noisy.

With a pack whose gbuffers_water (or a fallback down gbuffers_terrain's
chain) loads, translucent terrain (water, stained glass) is drawn by it
after the deferred programs and before the composites, in place, sorted
back to front as the game sorts it, and Horizon's own translucent
terrain draw is skipped.
- blend.<program> (off, or four GL factors); translucent terrain
defaults to SRC_ALPHA ONE_MINUS_SRC_ALPHA ONE ONE_MINUS_SRC_ALPHA, and
only blendable buffer formats blend.
- depthtex1/depthtex2: depth without translucent terrain, a copy taken
just before it when a later program reads them (before it, depthtex0
itself). The hand is drawn after the pack, so depthtex2 = depthtex1.

- RGBA16 and R11F_G11F_B10F buffers get their own formats where the device has them
(16-bit normalized render targets need the adapter's format features): the float stand-in
kept NaN and values past 1, and BSL's TAA history went black for good.
- Textures share one sampler variable per kind (linear, nearest, repeat, nearest-repeat,
comparison): devices have as few as 16 sampler slots, Complementary's terrain program
declares 23 textures.
- A gbuffers pass reading the depth buffer or a buffer it draws into reads a blank texture
instead (a feedback loop: undefined in GL, refused by wgpu, and a crash here).
- A bind group layout that fails validation skips the program with the error's details
instead of ending the game.
- shadowModelView / shadowProjection (and inverses) for programs that read them before the
shadow pass exists: an orthographic camera 160 blocks each side, toward the shadow light.
- HORIZON_SHADER_PACK_SKIP=a,b leaves programs out (a developers' aid to bisect a pack).

`uniform.<type>.<name>` and `variable.<type>.<name>` of shaders.properties (3.4): an
expression parser with C precedence, the function table (math, vectors, `if`, `between`,
`equals`, `smooth`, `random`...), evaluated on the CPU once per frame in file order after the
frame's own uniforms. `smooth` keeps its state per call site and halves the distance to its
target every fade time (OQ-26 working answer). A name neither the frame nor the pack defines
reads 0 and is listed once in the log.

naga keeps only constant initializers of globals, so every initialized global that is not
`const` (and every conditional one) gets its value from a function of ours that main calls
first, one per declarator, converting as GLSL's initialization does (`vec2 v = atlasSize`).
`vec3 a = x, b = y;` no longer loses `b`.
Program-enable expressions (3.3) now see the pack's switch options that are on by default
(8.1): `#define NAME` with nothing after it, tested with `#ifdef`/`#ifndef` anywhere in the
pack (OQ-13 working answer). BSL's `deferred` (ambient occlusion) and its TAA ran with options
off before.

PrimedTnt keeps Entity's NO_OP InterpolationHandler and ticks on a client
too: a position packet puts it there at once, its own tick moves it on
(gravity, collisions, bounces, drag) and burns the fuse down, and a client
discards it when the fuse runs out. Horizon interpolated it towards each
update instead, so it trailed about two ticks behind the server.
lan_e2e's falling check now drops primed TNT too and checks that the
guest has it exactly where its fall from rest puts it for the fuse the
server sent.

With a pack whose gbuffers_terrain (or a fallback) loads, solid and
cutout terrain is drawn by it into the pack's buffers, in place, between
prepare and deferred, and Horizon's own solid terrain draw is skipped.
- depthtex0 is now a Depth32Float attachment: the blit writes the
world's depth there (GL window depth, GL rows), terrain tests and
writes against it, so entities and terrain occlude each other; later
programs sample it as before.
- The vertex glue reads Horizon's TerrainVertex on both draw paths
(instanced, and flat with the page tables in bind group 1) and gives
atlas coordinates, lightmap coordinates in 0-240, the vertex colour,
mc_midTexCoord at the sprite's centre and mc_Entity = -1. Normals,
tangents and block ids come later.
- texture/gtexture/tex sample the block atlas, lightmap the lightmap;
atlasSize is set.
- Occlusion culling is off while a pack draws terrain (it reads the
depth of Horizon's terrain draw), and flat draws stay on.
- Uniforms a program reads that are not provided yet are reported.
- Program building is shared by quads and terrain (build_pass, bind).
- terrain-test: Horizon's own pack for this slice.
