A demonstration of deterministic knowledge bundles with canonical verification.
This demo shows how a structured knowledge state can be:
- captured in explicit semantic fields
- transformed into a canonical representation
- hashed with SHA-256
- verified later for integrity
- checked for drift or tampering
The core idea is:
same structured input → same canonical state → same hash → same verifiable state
If the state is changed afterwards without recomputing the canonical representation and hash, verification fails.
The app demonstrates:
- structured knowledge capture
- canonical serialization
- deterministic hashing
- bundle verification
- tamper / drift detection
- separation between UI models and Core contract models
- adapter-ready architecture for future DigiEmu Core integration
The demo is based on the idea that AI systems should not only generate outputs, but should also be able to anchor those outputs to a verifiable knowledge state.
Instead of treating knowledge as loose text or transient context, the system structures it into fields such as:
- Meaning
- Claim
- Uncertainty
- Provenance
- Confidence
- Tags
- Event Timestamp
That structured state is then serialized canonically and hashed.
This makes it possible to prove whether the knowledge state is still identical later, or whether it has changed.
This demo is Core-aligned, but it is not yet running the full real DigiEmu Core runtime.
What is already implemented:
- deterministic bundle construction
- canonical JSON generation
- SHA-256 hashing
- verification logic
- external Core bridge architecture
- contract separation between UI and Core models
What can be added later:
- direct integration with real DigiEmu Core services
- exact production bundle schemas
- signatures
- verifier reports
- replay-based state reconstruction
- compliance-oriented audit extensions
The demo supports two modes:
demo-localcore-http
Uses the local fallback implementation.
Uses the server bridge for external Core integration.
If configured, it can fall back to demo logic when the external Core service is unavailable.
