WebGL GPU planet-climate engine

3D globe surface, icosahedral dual-hex grid

Four stacked layers (High Air, Low Air, Surface Ocean, Deep Ocean), explicit time-stepping, finite-volume advection, diagnostic hydrostatic pressure. Cryosphere CO₂ cycle + Biosphere

planet/ = browser app + shaders, harness/ = headless test/bench tooling.

repository history

TODO: need to pick plans and reports to archive from old branches.

This reconstructs the full development history from flat snapshot folders (p.zip, kept on main, see archive/):

• archive/HISTORY.md — snapshot tree, branch map, aliases, chronology notes
• archive/RESTORE_PLAN_IMPROVED.md — reusable method for such reconstructions
• archive/rebuild_history.py, archive/verify_history.py — the v2 transplant scripts (each snapshot tag re-verified against its folder)
• archive/restore-history-plan.orig.md, archive/filelist.orig.txt — inputs
