Talus-3.1 (flat-terrain variant)

Talus-3.1 is a variant of Talus-3 for flatter maps. It is closer to real maps on plains, islands and mesas, and further from them on hills, mountains and ridges. Talus-3 (v3.0.0) stays the default. Use Talus-3.1 when your maps are mostly flat ground, coastlines or plateaus.

How it differs from Talus-3

Per-type realism on the held-out TEST split (distance to real maps over the real-vs-real noise floor, lower is better):

	plains	islands	mesas	hills	mountains	ridges
Talus-3	1.17	1.21	1.43	1.16	1.71	1.80
Talus-3.1	1.13	1.16	1.33	1.20	1.75	1.93

Scorecard (0-100, higher is better): Realism 64.5 (Talus-3: 66.2), Spectrum 11.3 (11.0), Slopes 59.0 (60.5), Control 92.4 (92.1), Playability 99.3 (99.9), Originality 98.4 (99.1). Average 79.7 (80.3).

How it was made

Talus-3 continued for 12,000 steps on 96,000 procedural maps it had never seen (same generator, new seed). We picked it on the validation split as a variant before running TEST, and TEST could not change the default. Training, selection and memorization checks: docs/TALUS31.md.
