Proves Theriapolis.Core works untouched under Godot's csproj — the worldgen
pipeline produces byte-identical output whether invoked from the Tools CLI
or from inside the Godot process. This is the determinism contract surviving
the port.
Architecture test:
CoreNoDependencyTests now forbids Godot.* and GodotSharp in addition to
Microsoft.Xna and MonoGame. Both bans stay in force for the duration of
the port so neither engine can leak into Core.
Determinism oracle:
New worldgen-hash Tools command runs the full pipeline and prints FNV-1a
hashes for every channel (elevation, moisture, temperature, biomes,
settlements, polylines) plus per-stage hashes. Pairs with the Godot
smoke-test for cross-process verification.
Godot-side smoke test:
SmokeTest.cs runs WorldGenerator.RunAll inside the Godot process; Main.cs
fires it on --smoke-test <seed>. Resolves Content/Data via res:// walk-up.
M0 hello-world behaviour preserved when launched without the flag.
Verification (seed 12345):
- dotnet run -- worldgen-hash and Godot --headless --smoke-test agree on
all 6 channels and all 14 per-stage hashes (diff produces zero output)
- 10-run sweeps stable on both sides post-determinism-fix
- dotnet test: 708/708 pass
