trustgraph-jac

TrustGraph Jac/Jaseci OSP walker for agentic knowledge verification.

Built on top of trustandverify — the Python package that implements all confidence algebra, search backends, storage, and export. This package provides the Jac/Jaseci graph layer: OSP nodes, edges, byLLM functions, and the agentic walker.

Enhanced from the Velric Miami Hackathon 2026 implementation. Fully additive — hackathon usage works unchanged.

Install

pip install trustgraph-jac

Requires API keys:

export GEMINI_API_KEY=...
export TAVILY_API_KEY=...

Usage

Same as hackathon (unchanged)

jac run trustgraph.jac
jac run trustgraph.jac "Is nuclear energy safer than solar?"
jac run trustgraph.jac "Is coffee healthy?" --claims 5

New in 0.2.0

# Multi-backend search (Tavily + Brave + Bing, deduped)
jac run trustgraph.jac "Is remote work productive?" --search multi

# Export all formats
jac run trustgraph.jac "Is coffee healthy?" --format all

# Persist to SQLite
jac run trustgraph.jac "Is coffee healthy?" --storage sqlite --db reports.db

# Full options
jac run trustgraph.jac "Is nuclear energy safer than solar?" \
  --claims 5 \
  --search multi \
  --storage sqlite \
  --db reports.db \
  --format all

What's in this package

What moved to trustandverify

All confidence algebra, search backends, storage, and export logic now lives in the trustandverify Python package. The Jac layer focuses on what Jac is good at: graph structure, byLLM functions, and the agentic walker pattern.

Hackathon compatibility

The bridge modules preserve the exact import signatures from the hackathon:

import from bridge.confidence {
    scalar_to_opinion, flip_opinion, fuse_evidence,
    apply_trust_discount, detect_conflicts_within_claim,
    opinion_summary, build_jsonld_claim
}
import from tools.search { web_search }

These still work — they now delegate to trustandverify instead of having inline implementations.

New node fields (0.2.0)

The Claim node now stores explicit opinion components for graph queries:

claim.opinion_belief      # float
claim.opinion_disbelief   # float  
claim.opinion_uncertainty # float

Previously only claim.confidence (projected probability) and claim.status (verdict string) were stored.
