IrisEntity.spawn waited on J.sfut(...).get() to move the spawn point below
ground. J.sfut schedules the task for the next main thread tick, so when spawn
already runs on the main thread (ambient spawning in WorldEntitySpawner) the
future can never complete and the server stops ticking. Run the check inline
when already on the main thread.

A 3D view asked for a frame while its card was hidden, for example when
the sidebar resized, showed its GPU window again. AWT maps a shown
canvas even under a hidden parent, so the window covered the open view
in black. Frames only go into the window while the view is on screen.
Model used: Opus 5.5
- The route-and-reject hydrology system and its probes are removed
- Hydrology is configured under dimension hydrology and per biome, region and dimension hydrologyPolicy
- riverPolicy and the old hydrology config types are gone
- Grid kernels cover priority flood, D8 routing, flow accumulation, basin extraction, breaching and stream burning
- A basin spills at its pour point and an interior bump can never be the spill
- Region plans cover 4096-block regions on a 64-block grid for major rivers and lakes
- Window plans cover 512-block windows on an 8-block grid for reaches and ponds
- Plans are cached in memory, persisted per world under iris/hydrology and keyed by pack, seed, world height and settings
- Only the main runtime of an engine persists plans and stores swap on hotload and default runtime change
- Demand rasters outrank prefetch and stopping pregen withdraws its queued prefetch
- Ponds come from natural basins, seeded cups and chained cups with strictly falling levels
- A pond level never exceeds its rim plus maxFill or the end grade of any inflow
- Pond outlet loops are opened at their lowest pond
- Reaches split at junctions, pond outlets and 256-block grid lines
- Reaches meander, fit the valley, grade to a running minimum and smooth with Chaikin passes
- Drops of two blocks or more get a lip and one-block corner steps become dry rim ledges
- Cascades and waterfalls write falling fluid from the mantle at level eight
- Inflows into region lakes end at the lake level
- River mouths and water beside the sea sit at the sea surface
- The per-chunk raster gives terrain height, water head, role, tier, fluid, cave ceiling and shore distance
- WaterRole codes are stable and exposed to packs through the WATER_ROLE engine stream
- WATER_HEAD replaces the old river engine streams and an unknown stream name fails the pack load
- Banks take SMOOTH, LINEAR, CONCAVE, TERRACED or CLIFF profiles
- Containment berms grow as tall as the water needs
- Columns within two blocks of water stay solid and keep no Terrain3D overhang
- Seam dams hold water where new chunks meet chunks generated earlier
- The transition blend skips hydrology-owned columns
- Caves stay at least two blocks below river and pond beds
- The painter is the only writer of still water
- Objects cannot open water, falls or bank ground and solid objects may stand in water
- On-water objects need fluid at their anchor column
- Floating child islands stay out of channels
- Sea inlets run inland from cliff coasts at sea level and end in a chamber pool
- Inlet passages are sealed against carvers, subterrain features and the post pass
- Cave pools settle into carved lows, keep one fluid and stay out of inlet space
- Pool and inlet cells use their own cave actions in mantle data
- Water vegetation lists sit on tiers, ponds and hydrologyPolicy with SEA_FLOOR, SEA_SURFACE and SHORE_LINE parts
- Pack validation compiles hydrology settings and rejects empty or water-holding palettes
- Chunk generation fails closed when its 3x3 water rasters are not planned
- /iris find covers stream, river, major river, cascade, waterfall, mouth, pond, lake, dam, sea inlet and cave pool
- Generation history records the new feature types and drops old hydrology entries
- The studio map draws water from rasters up close and from plans when zoomed out
- Pregen prepares the current region and one region ahead
- hydrologyProbe, riverTransectProbe, hydrologyBlockProbe, seaInletProbe and cavePoolProbe report containment, rises, seams, tick conversion and missing surface
- Test forks run with a 2 GB heap, a 60-minute timeout and the Mockito agent loaded explicitly
- Generation with hydrology off is unchanged
Switching source kept nothing on screen until the new one drew. The old
frame now stays until the first new frame lands, then fades out over it
in 150 ms.
Model used: Claude Opus 5.5
Switching palettes dropped the last frame's timing, so the first frame
fell back to one sample per ~29 pixels and drew a texture pixel in each
square. The first frame is now sized from the previous source's speed,
and coarse frames use block colours instead of texture pixels.
Model used: Claude Opus 5.5
Icons now show each box's top above its front, half as deep and lit as
Minecraft lights each side, so sea pickles, candles and eggs show caps.
Model used: Claude Opus 5.5
A frame asked for while the last one was being taken, like the one that
ends a load, was drawn and swapped before the earlier frame's swap, so
the window kept the old object until something else redrew it.
