🤖 Agent: advancements= in a selector reads the selected player's own progress, a guest's included (EntitySelectorOptions on the ServerPlayer); guest_advancement_selector passes on the merge, now runnable by parity.py.
🤖 Agent: roadmap.toml is the source; ROADMAP.md and roadmap.json regenerated (build --check passes). older-servers kept on purpose (1.8 PvP servers), only the sign-in item goes.
Mojang's approval covers Microsoft sign-in only; other account providers
(Ely.by, Yggdrasil servers) are against the rules Horizon plays by, so the
item can't ship. #1270 stays closed.

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

🤖 Agent: a copper chest someone has open now skips its weathering step (WeatheringCopperChestBlock.randomTick checks getEntitiesWithContainerOpen); random_tick and random_tick_sections harnesses passed.
🤖 Agent: using items (fishing rod, ender eye…) now posts vanilla's item-use game events through causeUseVibration, so sculk sensors react as in Java; sculk, server_player_sculk, server_wool_vibration and use_item_on pass against the 26.3 oracle in the gate's harness run (242 selected; failures were host setup only plus the lunge_motion timing flake).
🤖 Agent: crafting with a merchant result slot now fires vanilla's merchant crafted trigger and updates the trade, checked by the new --merchant-crafted-fixture in command_exec; merchant_crafted, command_exec and trading pass against the 26.3 oracle in the gate's harness run (242 selected; failures were host setup only plus the lunge_motion timing flake).
🤖 Agent: item entities, armor stands and boats now save the shared Entity flags (Invulnerable, CustomNameVisible, Silent, NoGravity, Glowing, HasVisualFire, Tags) as vanilla's saveWithoutId does. Its 242 selected harnesses ran on main + this head + #11017 + #11022: save_roundtrip, world_reopen, entity_nbt_boolean, the armor stand and boat ones pass; the only failures are setup (no sound/lang assets on the host, harness args) and the known lunge_motion tick-timing flake under software rendering.
🤖 Agent: overflow honey now leaves through Player.drop (eye height − 0.3, thrown along the view, pickup delay 40) instead of popping at the feet; held_drop harness passed, plus Game tests for Peaceful anger and event 2011.
🤖 Agent: the device list is now read on a worker thread, so a slow Windows audio driver no longer stalls a frame; the render thread only swaps in the result. No vanilla behaviour changes, no harness covers it.
🤖 Agent: effects now carry vanilla's showIcon apart from the particles (5-arg constructor, update, save codec default, packet bit 4), so warden Darkness and /effect hideParticles no longer show a HUD icon; 8 effect/HUD/sculk harnesses pass.
🤖 Agent: lightning now places fire (and draws its extra-source offsets) only when canSpreadFireAround passes at the bolt, so fire_spread_radius_around_player holds for strikes far from every player.
WeatheringCopperChestBlock.randomTick runs changeOverTime only when the
chest's getEntitiesWithContainerOpen is empty, so an open chest neither
oxidizes nor draws its odds (part of #11378).

🤖 Agent: the Mods page's install and port messages go through tr/trf with named arguments, so they translate; lang files merged key by key onto main, i18n tests pass.
🤖 Agent: a mob's Absorption now refills on every accepted add (AbsorptionMobEffect.onEffectStarted), and heal/harm and effect intervals shift like Java's int << / >> (distance mod 32, wrapping) instead of clamping or panicking at amplifier 32+.
- NeutralMob.isValidPlayerTarget also fails on Peaceful: a bee's anger at
the player ends there.
- BeeGrowCropGoal sends level event 2011 (data 15) before the crop grows;
the client draws it like 2012 (spawnParticleInBlock, happy villager).
- A honey bottle that no longer fits is player.drop(stack, false): from
below the eyes, thrown along the view, no thrower (#11377).

🤖 Agent: an empty frame now refuses a map tracking more than 256 counted markers (ItemFrame.interact's isTrackedCountOverLimit FAIL): the map stays held, no swing; exactly 256 still goes in.
🤖 Agent: /say from a command block reaches every player under the block's name, and a captured guest command no longer echoes it back as feedback (kacpherek's point); lan_e2e command-block-chat not run here.
LightningBolt.spawnFire places fire, and draws its extra sources, only when
ServerLevel.canSpreadFireAround passes at the bolt: the
fire_spread_radius_around_player rule now holds for lightning (#11376).

🤖 Agent: the omen sound now plays from the player's addEffect for any newly added omen (command, potion, mod) at the feet, as MobEffect.onEffectAdded does; the three special paths moved from the eye to the feet too.
🤖 Agent: TNT, falling blocks and XP orbs now collide with boats, shulkers and a held happy ghast (Entity.collide's canBeCollidedWith); sand landing on a boat over air breaks into an item like vanilla's wouldContinueFalling.
🤖 Agent: 0.2 shader packs get the float HDR frame only under HORIZON_HDR_FRAME=float; the default and 0.1 paths keep their formats (frame_format tests cover both), so the vanilla look is unchanged.
MobEffectInstance.showIcon was not modelled: every effect showed its HUD
icon and every UpdateMobEffect carried the icon flag. Warden Darkness
(no particles, no icon) showed an icon. The flag now follows vanilla's
constructors, update, saves (show_icon defaults to show_particles),
consume effects and the packet flags (#11385).

🤖 Agent: a loaded furnace keeps its saved cooking total until the item finishes, and a hopper or dropper filling the empty input slot restarts the cooking as setItem does (kacpherek's point); furnace_loaded_total and furnace_output_components pass.
🤖 Agent: a restored chat draft draws grey italic until edited, as ChatScreen's isDraft does; text a mod opens chat with is not a draft. Merge with main builds and the chat tests pass.
ItemFrame.interact returns FAIL when MapItemSavedData.isTrackedCountOverLimit(256):
the map stays in the hand and the frame stays empty (part of #11383).

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

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