Diod v0.1.0.11 — One Earth, one world generator
Pre-alpha | 22 October 2026

Changes since v0.1.0.10
- New games start at the geographic coordinate of Fleminggatan 109, Stockholm (59.334993 N, 18.027543 E). The surface is naturally reclaimed Earth, without modern streets or buildings.
- One Earth-based generator now supplies terrain, collision, distant scenery and local map detail everywhere in new worlds. The starting square no longer has a separate terrain pipeline or an outer blending band.
- Terrain detail, climate-driven ecology, trees, gatherables and mineral deposits use geographic rules. Removed starter iron, fibre and stone injections and reachability rerolls from new Earth worlds.
- Global vector shorelines preserve land, lakes and islands more accurately than the old coarse water mask, including the land at the selected Stockholm coordinate.
- Mineral deposits and clues generate regionally beyond the former starting square; weathered iron beds follow suitable host geology everywhere.
- Generation rules are frozen with new worlds. Existing saved worlds retain their original terrain and resource records. Archive guidance now describes ordinary landscape resources.

Implementation and precise limits: docs/EARTH_ENGINE.md. Global source data notices and corresponding-source download accompany the release. One heavyweight Godot/build/sign process at a time. Owner/local GPU playtesting is the visual acceptance loop.

Validation
linux: Focused actual-export checks cover geographic terrain and resource invariance, exact dry Stockholm bunker placement, no starter injections, shared terrain/collision borders, ocean water, frozen generation rules, natural mining, save/reload and legacy terrain, plus existing landform, stone-crafting and navigation checks. No full-world GPU playtest. Actual exported content/Earth/legacy-save path identity passed. No full-world GPU playtest.
windows: Sequential export, native icon groups/sizes and four-part version checked. Native Windows GPU playtest pending.
macos: Universal bundle identity/version and x86_64/arm64 verified. Fresh Developer ID signed, Apple notarized and stapled. Native Mac GPU playtest and fresh Gatekeeper assessment pending owner/local testing.

Known issues
- Native Mac/Windows GPU gameplay testing and fresh Mac Gatekeeper assessment await owner/local testing.
- Earth elevation/climate remain coarse source data; generated fine detail is not surveyed metre-scale terrain. Geology is procedural and warmer forests still use existing temperate tree art.
- River vectors provide shared courses, but full global catchment/tributary/erosion simulation and upstream-provenance river placers remain unfinished.
- Long-distance spherical travel projection/floating origin, polar refinement and region-partitioned saves remain future infrastructure work. This release does not establish full-Earth persistence scalability.
- Natural resources are no longer guaranteed near the bunker. Some starting locations require more exploration to find particular host rocks and supplies.
