beezm d72ffc0183 docs: bring all READMEs current with actual code (post-sweep-10 truth pass) 
Every README was read first, checked against the code in its directory, then
rewritten to describe what the code actually does now.

Corrected throughout: map size is config-driven (8192 default) not a fixed
4096; chunks are 24x24x256 not 32x32; road carving is implemented for all four
tiers, not a 'next step'; Data/ and Resources/ are empty, not populated.

Also fixed MATH_MARCHING_CUBES.md, which documented the density sign convention
exactly backwards — it claimed positive was underground, where the code treats
positive as above the surface and counts a corner inside when density < iso.
Getting that backwards inverts every normal, a bug this project has hit before.

The root README now carries accurate run steps: F5 runs the map generator (not
the game), F6 on Scenes/Main.tscn runs the 3D world, and ChunkRadius is a load
radius that should be dropped to 4-8 while iterating.

Docs only. No code changed.

README.md

/Core/Scripts

Pure C# data structures, shared enums, and static maths. Compiled into the shared assembly used by both /Server and /Client.

"Pure data, zero state." These scripts define what things are and how to calculate them. They never track live game events — who is online, which chunks are loaded, what time it is.

What's actually here

Voxel materials

  • BlockData.cs — struct describing one block type (ID, name, IsSolid, BaseColor).
  • BlockRegistry.cs — the byte-ID master list (AIR 0, BEDROCK, STONE, DIRT, SAND, the three grasses, SNOW, WASTELAND_DIRT, ASPHALT) with a safe GetBlock lookup.
  • BiomePalette.cs — decides which material sits where, given biome, depth, and whether the column is roadbed. Two paths on purpose: an integer classification that decides what is stored in each voxel, and a float-depth version used for rendering that returns the two materials either side of a boundary so colours fade rather than snap.

⚠ Note that BlockRegistry and the mesher's colour table hold different RGB values for some blocks. The mesher's table is what you actually see; BlockData.BaseColor is currently unused by rendering.

Shared identifiers

  • Enums.cs — Biome, TownTier, MapHalf, RoadTier.

    ⚠ Biome and TownTier are the .dat wire format. They are declared without explicit values, so each member's ordinal is the number written to disk, with no version gate and no validation on read. Append only, at the end — never reorder or insert. Doing so silently reinterprets every pixel and every settlement in every existing blueprint. RoadTier is exempt: road tiers live in separate sections of the file, so it is never serialized.

World data

  • MapDataParser.cs — decodes the .dat blueprint into a WorldBlueprint (heightmap, biome map, towns, four road tiers).
  • ChunkData.cs — one chunk's density and block-ID fields, +1 padded on every axis so the mesher can reach into the neighbouring chunk, plus the per-column data the renderer needs.
  • Constants.cs — chunk dimensions, ISO_LEVEL, VOXEL_SCALE, and the visual/road tunables (material blend band; per-tier road width, shoulder, grade smoothing and surface).

Maths

  • MarchingCubes.cs — density field → ArrayMesh, with analytical normals and deterministic integer-keyed vertex welding.
  • MATH_MARCHING_CUBES.md — an explainer of the algorithm.

Rules

  1. No Godot node inheritance. Pure classes, structs and statics.
  2. No _Process / _Ready. Nothing here is attached to a live scene object.
  3. Dependencies flow inward only. /Server and /Client reference /Core; /Core never references them.
