arti.nn

Symbol	Role
Layer	Compact, profile-driven entry point
Half	Salience-conditioned activation
Fold	Latent workspace compaction
UnFold	Value-preserving, layout-changing expansion with dynamic target_length
Pulse	Learned pulse formation
RecallRefiner	Iterative latent recall refinement

FusionPulse is a separate Alpha layer for fusing several already compact Pulse workspaces into a fixed [B,K,D] workspace. Its structural-loss defaults are not part of the frozen core surface.

Root core

• ARTILayer, ARTIResidualBlock, ARTISequenceBlock, and ARTIPooledBlock
• ARTIClassifier
• ARTI.attach and attachment configuration
• save, load, and migrate_pt

Literal and runtime vocabulary — alpha

• TextTensorRenderer, render_text_layout, and render_text_tensor
• BitmapTextRenderer, render_text_bitmap, and render_text_vocab
• RuntimeVocabEncoder, LiteralInput, and LiteralOutputHead
• OutputLexiconContext, LiteralVocabCache, and LiteralSequenceDecoder

Local IDs are meaningful only under the vocabulary tensor supplied for that call.

Representation and routing

• Source-integrity carriers, reports, and training losses
• Membrane visibility routing
• Phase and rotating coordinate frames
• Half, Fold, Pulse, and UnFold workspace composition
• FusionPulse multi-source consolidation
• VisualField, VisualScan, layered Recall, and Recall TTT utilities

Deployment and backends

• arti.torch: backend-explicit PyTorch aliases
• arti.jax: native functional subset with JIT, PyTree gradients, VMAP, masks, visibility, and coordinate-frame inverse
• arti.web: Python-owned ONNX export, generated artifact client, browser loading, inference, and bounded stateful Recall
• arti.functional: masks, visibility, pooling, coordinate frames, and activations

JAX does not implement fitting, attachment, Recall, Membrane, Half/Fold/Pulse, or the full module stack. Web Binding remains alpha and inference-only.

Experimental boundaries

Symbols documented as alpha, experimental, or legacy are not frozen at the same level as the supported core. Check docstrings and the stability policy before depending on them.
