v0.3.0-v4-preview - V4 architecture (untrained preview)

V4 architecture preview — untrained.

This pre-release publishes the V4 graph-native architecture (Unified Dynamic Token-Concept-Relation Graph Causal LM) as code + design docs only. There is no trained checkpoint: V4 is component-smoke-tested but not validated as a working language model. The trained, released line remains Stage C / V3 (see v0.2.0-stagec).

Included:

• V4 model / dataset / training entry + 8 contract smoke tests
• V4 teacher-labeling + audit pipeline
• 20 V4 design documents + architecture paper
• Browser-based training-data audit UI

Shared for architecture review and collaboration.
