Diod v0.1.0.52 — Pre-alpha

- Explore the connected globe with nearby terrain, water and scenery streaming around the player. The world atlas does not load distant 3D terrain.
- Play in first person, including walking, digging, swimming, placement and boat seating.
- Craft a wooden rowing boat at level 1 with 16 split timber and 6 cordage. Place it in open water, press E to board, W/S to row, A/D to steer and Shift to row faster. E disembarks.
- Preserve geographic position, boats, source-anchored structures and chest contents across travel and save/reload.
- Fix recurring rendering freezes caused by world-generation jobs occupying engine workers. Improve Medium rendering settings, collision generation and excavation sampling.
- Keep shovel and pickaxe excavation, underwater cuts and finite water inflow working across travel, with repaired ground walking and map display.

Save compatibility
Continue an existing v51 African journey; its baseline terrain, excavations, structures and inventory are retained. Earlier regional saves remain separate and untouched. Close the game before replacing the application. Back up experimental saves before upgrading; do not downgrade a v52 save into v51.

Known limitations
- Initial loading remains slow: approximately 32 seconds at Low/160m and 50 seconds at Medium/640m on the tested Apple M4.
- Complex cave and cube-corner excavation rebuilds can take several seconds; geographic view publication can briefly pause for approximately 0.1–0.25 seconds.
- Water, rowing animation, boat presentation and dedicated first-person arm artwork remain unfinished polish.
- Windows/Linux GPU, Intel Mac and physical controller acceptance have not been established. Windows publisher signing is not configured.
- The large market/travel ships remain moored; the small craftable boat is steerable.

Development acceptance: native Mac globe route 34 checks, reload 8, mounted automatic boat travel 6 and reload 6, actual dry digging/walking 13 and reload 5, wet excavation/swimming/handoff 16 and reload 5. Dedicated generation-worker isolation 7 checks. Medium 640m maximum-map plus 60s walking: 2486 frames, median 23.649ms, p95 30.006ms, maximum 76.241ms. These are specific Apple M4 routes, not all-hardware FPS guarantees. Final exported-artifact validation is recorded in download metadata.
