Source provenance
None — training data opaque, sources unverifiable
Full — every claim traced to exact source document, version, and ingestion timestamp
Confidence grounding
Fluency-based — confident prose regardless of underlying knowledge quality
Six-lens deterministic scoring — Leighton Weight as a Linearly Scaled Epistemic Vector Calculation
Scoring mechanism
Model inference — non-deterministic, different result possible on identical input
Deterministic rule-based logic — identical input always produces identical output
Temporal validity
Training cutoff opaque — model cannot know if its knowledge is current
Flagged at ingestion — domain-specific decay thresholds, re-validation scheduled automatically
Versioned knowledge
No versioning — updated training data silently replaces prior knowledge
Supersession edges — prior versions immutable in store, current version highest-weighted
Audit trail
None — no traceable path from output to source
SCP capsule per interaction — causally ordered, cryptographically hashed, regulator-ready
Hallucination risk
Inherent and architectural — cannot be engineered out of a generative model
Structurally eliminated — Extractive Semantic Translation Layer cannot generate content outside the validated store
Data sovereignty
Data sent to third-party infrastructure — vendor terms govern processing and retention
Fully sovereign — no cloud dependency, no external API, no data leaves the organisation
Human accountability
Systemic liability — when it fails, no individual is accountable
Classical professional accountability — every human-gated claim cryptographically signed by the approving operator
Offline capability
Cloud-dependent — requires connectivity for every query
Offline-first — full capability on device with no network connection required
Regulatory readiness
Requires extensive human review overlay as a workaround
Provenance-native — audit-ready by architecture, not by process overlay
EU AI Act classification
High-risk AI system in regulated domains — significant compliance burden
Rule-based deterministic system — categorically distinct from high-risk AI under the Act
