TVC Distributed Learning

TVC (Ternary Vector Corpus) is Trinity's distributed continual learning system. It provides zero-forgetting knowledge storage using ternary vector embeddings, bundled into a persistent corpus for instant retrieval.

Architecture

How TVC Works

1. Query embedding: User input is converted to a 1,000-trit ternary vector
2. Similarity search: Cosine similarity is computed against all corpus entries
3. Threshold check: If similarity $\geq \phi^{-1} = 0.618$, it's a cache hit
4. Hit: Return cached response instantly (no LLM call needed)
5. Miss: Call LLM, then store the query-response pair in the corpus

Zero-Forgetting Bundling

TVC uses the VSA bundle operation (majority vote) to accumulate all learned patterns into a single memory_vector. This means:

• No patterns are ever discarded
• New knowledge is bundled with existing knowledge
• Retrieval uses cosine similarity against the bundled vector
• Capacity: 10,000 discrete entries + 1 bundled memory vector

Comparison with TextCorpus

Feature	TextCorpus	TVC Corpus
Capacity	100 entries	10,000 entries
Vector type	Float32	Ternary 1
Memory	~40 MB	~26 MB
Compression	None	20x (vs float32)
Forgetting	FIFO eviction	Zero-forgetting
Bundling	No	Yes (majority vote)
File format	JSON	.tvc binary

File Format

TVC files use a binary format with a TVC1 magic header:

Offset  Size    Field
0x00    4       Magic: "TVC1"
0x04    4       Version
0x08    4       Entry count
0x0C    4       Vector dimension
0x10    48      Reserved
0x40    ...     Entries (vector + metadata)

Sacred Mathematics

The TVC threshold is derived from the golden ratio:

$\text{threshold} = \phi^{-1} = \frac{1}{\phi} = \phi - 1 = 0.6180339887...$

This is the Needle threshold (Koschei's Needle) — the minimum similarity required for a cache hit. The number $\phi^{-1}$ is the reciprocal of the golden ratio and appears throughout Trinity's architecture as the quality gate.

Integration with Chat

TVC is automatically loaded when starting the REPL or using tri chat:

# TVC is loaded automatically
tri chat "What is VSA?"

# First time: LLM call + stored in TVC
# Second time: instant cache hit
tri chat "What is VSA?"

The TVC corpus persists across sessions via the trinity_chat.tvc file.
