Diod v0.1.0.13 — A clearer world and road forward
Pre-alpha | 22 October 2026

Changes since v0.1.0.12
- New-world terrain models sheltered hollows, exposed mountain ribs and softer walking ground from shared geographic relief rules, with no starting-area treatment.
- Climate and landforms guide moisture, glades, groves, moss and meadow patches. Regional rock families remain guided by GLiM. These are generated interpretations of the existing Earth data.
- Unexplored regional maps render at higher resolution with multi-direction relief shading, elevation tint, adaptive contours, vector coastline/lake boundaries and visible river courses. Visited surveys remain distinct and viewing never discovers ground.
- Roadmap opens as a whole-tree overview with zoom, pan and next-objective focus. A responsive side inspector keeps objective steps and Craft links accessible without squeezing the tree.
- Roadmap cards show item artwork and colored branches/completion states. Pause tabs, quick crafting and health/food/stamina bars gain clearer icons and colors.

Implementation: docs/EARTH_ENGINE.md, docs/EARTH_DATA.md and docs/ROADMAP.md. The bundled Earth datasets are unchanged. Old generator profiles retain their terrain formulas. One heavyweight process at a time; local GPU playtesting remains the visual acceptance loop.

Validation
linux: 216 focused actual-export checks: Earth metadata/compatibility 18, terrain 49, progression/Roadmap 89, navigation/cartography 33 and tool stones 27. Small software-rendered Roadmap fixture reviewed. 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.
- Elevation remains the existing coarse ETOPO grid; geology remains regional GLiM. No new high-resolution DEM, full erosion simulation or complete small-stream network is included.
- Whole-tree overview deliberately reduces card text; select a card for full-size details or zoom in. Existing regional species art remains unchanged.
- Global travel projection/floating origin, polar refinement and huge-settlement simulation remain unfinished.
