🤖 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.
🤖 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+.
🤖 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.
🤖 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.

🤖 Agent: the item name and the action bar take fixed heights above the hotbar (Hud.extractSelectedItemName 59, extractOverlayMessage 68) instead of following the bars; hud harness passes on a union with main.
🤖 Agent: a breeze turns a thrown potion back at half speed (Breeze.deflection) once in a row, stopping at the hit point that tick; the REVERSE draw uses the potion's own random.
🤖 Agent: advancements with no criteria get their rewards on load (checkForAutomaticTriggers) but stay not done, as AdvancementRequirements.test answers false; checked on a union with main.
🤖 Agent: the fade out ending at startFadeIn now runs to the end of the day (since()==0 read as DAY), which was kacpherek's review point; checked on a union with main (fmt, clippy -D warnings, tests).
🤖 Agent: the solid terrain pipelines are built with HDR_LIGHTING off and the lit copy only exists when hdr_output is Some, so HDR players switch per frame by self.hdr; frame-identity label makes CI check HDR off, offscreen HDR and HDR toggled off in a running game. −16 to −22% GPU on M4 Pro, image identical in-process.
🤖 Agent: merging. Empty region files (13 303 of 13 620 in the test world) are no longer rewritten and synced on world open, and region files convert on all cores but one with byte-identical output; datafix harness 6/6.
terrain.wgsl's solid shaders carry HDR output's lighting behind a runtime
`hdr_light.z` test. The branch is never taken without HDR, yet on Apple GPUs its
code alone costs ~15% of the solid pass (register pressure). A pipeline
constant `HDR_LIGHTING` now guards it: the solid pipelines (per-section, pulled
and flat) are built without it, and a copy with it only where the display
offers HDR output, picked per frame by whether HDR is on.

🤖 Agent: the session state a client HUD reads (world id, screen kind) comes from fields the window already keeps; merged with #10195 and checked with clippy, the native_client tests and the hook stamp test.
🤖 Agent: client_hurt reports the packet's causing entity (the shooter, not the arrow) and treats an untracked entity as not a player, so a mod never gets a false PvP signal. Main merged in (test conflict with #11512's open-chat test, both kept); verify green on this head.
PrimedTnt, FallingBlockEntity and ExperienceOrb move with Entity.move,
whose Entity.collide includes EntityGetter.getEntityCollisions: a boat,
a living shulker and a happy ghast held still stop them, as they stop a
dropped item. Horizon resolved their moves against blocks and the world
border only (#11518). The ordered tick gathers those boxes once per run
(again after an explosion) and passes the nearby ones to each move.

A boat's passengers went to the clients in the order the players joined
the server, so the player who got in second could hear it sits first and
take the boat over, and the server took MoveVehicle from either seat: with
two players in one boat it kept snapping back (#11541). The passengers now
go in the order they boarded, and handleMoveVehicle ignores a player who
isn't the vehicle's controlling passenger, as vanilla does.

🤖 Agent: native_set_chat_input filters text to what typing allows (no control chars, DEL or §) and clamps the cursor, so a mod can't inject formatting codes into the chat box.
🤖 Agent: Launcher-only follow-up to #10529: the Home tab strip is flex_none on wide windows again (glass::tabbed keeps its notch at 1440 px) and only scrolls when compact; settings rows keep 40 px between name and control and wrap the control only when narrow. No new strings; fmt/clippy/tests green on the union of this wave's heads.
🤖 Agent: follow-ups to #11033/#11044/#11043/#11016 that missed the merges: death protection is one prototype lookup per hand per tick (was a full component map for every armed mob), checked against the component map for patched and stripped stacks. Union check: fmt, clippy -D warnings, 5666 tests green.
🤖 Agent: the interpolation change is checked bit for bit against the old formula over the test's whole range, so no position moves; one multiply fewer per entity per frame. Union check (main + the gate's 9 heads): fmt, clippy -D warnings, 5666 tests green.
🤖 Agent: inflates each region chunk in place instead of through a second buffer; the differential test decodes the same chunks with the old block decoder and compares every section. Union check (main + the gate's 9 heads): fmt, clippy -D warnings, 5666 tests green.
🤖 Agent: Optimize World now upgrades region files in parallel with one sync per file instead of one per chunk (F_FULLFSYNC on macOS was the cost); the 1-vs-4-thread test checks the counts against the fixture's own layout, and a canceled recreate leaves every file untouched. Union check: fmt, clippy -D warnings, 5666 tests green.
