UTE (working definition): a unified capability stack that can represent theories compositionally, retrieve and query with generalization, track provenance and contradictions, reason causally/mechanistically, handle uncertainty, support numeric models, revise models as evidence changes, and plan experiments to reduce uncertainty.

Why we treat UTE as a single theme

Each capability exists in isolation in many systems (logic engines, probabilistic programming, causal inference, simulators). The difficult part is the integration contract: one knowledge base, one query surface, one proof/evidence story, and one revision loop. We treat UTE as a research theme because it forces design decisions about:

Capability map (UTE = all of these)

Capability What it means in AGISystem2 Related today UTE research work
Compositional representation Relations, events, conditions, roles/slots; structure that supports both symbolic proofs and holographic decoding Core DSL + Core theory atoms (DS02, DS07*) UTE: Representation & Query · DS33
Query/retrieval with generalization Not just lookup: holes, analogy/similarity, explainable candidate generation Query + meta-ops + HDC priority (DS05, DS17) UTE: Representation & Query · DS33
Provenance + evidence + contradictions Trace what produced an answer, keep evidence objects, detect inconsistent subsets, support audits Proof-real direction (DS19) + contradiction detection in runtime UTE: Provenance & Revision · DS34
Causal / mechanistic reasoning Mechanisms, interventions, counterfactuals, causal graphs tied to executable rules Advanced reasoning topics (DS06) + planning/CSP foundations (DS16) UTE: Causal Reasoning · DS35
Uncertainty / probabilistic Confidence with semantics: priors, likelihood, probabilistic constraints, uncertainty propagation Confidence reporting exists, but not probabilistic semantics UTE: Uncertainty · DS36
Numeric modeling Quantities, units, equations, kinetics/PK, dose response, dynamics, parameter estimation hooks Some arithmetic patterns exist; no first-class numeric model layer UTE: Numeric Modeling · DS37
Model revision When evidence changes, revise theory/assumptions and keep a revision history Contradictions can be detected; revision policy is missing UTE: Provenance & Revision · DS34
Experiment planning Pick queries/actions to maximize information gain or reduce uncertainty under constraints Planning exists (DS16/DS07g), but not “experiment as uncertainty reducer” UTE: Experiment Planning · DS38

UTE pages

Representation & Query

Compositional modeling + generalization-aware retrieval; what we need beyond “holes” and similarity.

DS33

Provenance, Contradictions, Revision

Evidence objects, contradiction subsets, revision policies, and audit-grade traces.

DS34

Causal / Mechanistic Reasoning

Mechanisms, interventions, counterfactuals, and mechanistic models tied to rules.

DS35

Uncertainty & Probabilistic Semantics

Priors, likelihood, probabilistic constraints, and uncertainty propagation.

DS36

Numeric Modeling & Units

Units, dimensional analysis, equations, dynamics/kinetics, and estimation hooks.

DS37

Experiment Planning

Turn theory uncertainty into experiments/plans that reduce uncertainty under constraints.

DS38
