Human function is the body's capacity to be appropriately engaged to meet internal and external demands.
Human function is the organizing coordinate of HFWM, not the boundary of the modeled world.
HFWM continuously represents the same whole person across:
- internal and external tasks;
- Demand;
- required human-function capacities;
- current capacity;
- Actual Engagement Process;
- bodily structure and physiology;
- disease, injury, surgery, recovery and adaptation;
- manifestation, cost, boundary and reserve;
- evidence, uncertainty, hypotheses and judgment;
- governed action and responsibility routing;
- professional, caregiving and environmental coordination;
- feedback, reassessment and longitudinal change.
The operational reasoning chain is:
INTERNAL_TASK / EXTERNAL_TASK
→ Demand
→ Required Human-Function Capacities
→ Current Capacity
→ Actual Engagement Process
→ Response / Manifestation / Cost / Boundary / Recovery
→ Evidence / Hypotheses / Uncertainty
→ Judgment
→ Governed Action / Responsibility Routing
→ Observed Change
→ Feedback / Reassessment
→ Longitudinal Update
The UOHF root definition remains prior to this operational chain. Task representations make Demand explicit; they do not replace Demand in the root definition.
The term Human Function World Model (HFWM) was publicly disclosed by the same author in UOHF Definition 2.0 on 15 July 2026. That publication distinguished UOHF, the Individual Human Function Model, and HFWM, and described HFWM as adding time, action, transition, prediction, and memory write-back.
UOHF Definition 2.1 subsequently restored the full internal-and-external-demand root scope.
This repository is the dedicated public research home for HFWM as it grows beyond one manuscript.

The first publication defines the dedicated HFWM architecture; the interoperability study develops how heterogeneous models contribute to the same person; and the comparative study examines existing medical, physiological, health and computational modeling approaches, question-relative adequacy, evidence constraints and falsifiable evaluation. The comparative preprint reports conceptual analyses and constructed probes, not a validated benchmark or clinical benefit. UOHF remains the semantic authority for human-function definitions and governed ontology identities.
A targeted public search completed in August 2026 did not identify an earlier independent dedicated framework with the same organizing scope across internal/external tasks, human-function capacity and engagement, medicine-function bidirectional reasoning, responsibility routing, and longitudinal whole-person update. This is a provisional bibliographic statement and should be revised if earlier equivalent work is identified.
HFWM uses the public UOHF Human Function Capacity System as its governed functional coordinate.
Current public Version 1.0:
- 18 core human functional capacities
- 104 specific human functional capacities
HFWM does not create a second copy of the 104 definitions. UOHF remains the semantic authority.
See capacity-coordinate/README.md.
HFWM also requires explanatory scientific knowledge connecting human-function capacities to anatomy, spatial organization, physiology, biological processes, cross-capacity organization, response, state, time, and change.
The Functional Bridge is a governed knowledge-relation layer for this purpose.
Functional Bridge is:
- not UOHF A14;
- not a second ontology;
- not a replacement for formal UOHF relations;
- not person-specific evidence;
- not a diagnosis, causal conclusion, or action prescription.
Public scientific reference sources can include:
- Human Reference Atlas (HRA) for anatomical/spatial reference;
- NIH Whole Person Reference Physiome (WPP) for multiorgan and multiscale physiological reference;
- other controlled scientific sources with explicit provenance and scope.
See functional-bridge/README.md.
“Whole person” does not mean that HFWM claims exhaustive simulation of every molecule, cell, biological variable, social variable, or future.
It means that the persistent modeled entity remains the same person across biological, physiological, medical, functional, behavioral, environmental, professional, and longitudinal contexts.
Disease, injury, infection, surgery, and endogenous change may trigger internal tasks such as defense, regulation, hemostasis, repair, recovery, and adaptation. They are not themselves silently converted into Task or Demand.
HFWM connects medicine and human function bidirectionally without collapsing one into the other.
Medicine → human function: medical facts can constrain safety, physiology, capacity, engagement, recovery, task feasibility, and admissible action.
Human function → medicine: new or progressive functional change, unexplained deterioration, abnormal recovery, or failure of an existing functional explanation can generate a governed medical question or escalation need.
HFWM does not convert functional evidence into autonomous diagnosis.
See architecture/MEDICINE_FUNCTION_BIDIRECTIONAL.md.
HFWM can represent changing responsibility and collaboration across:
- physician;
- nurse;
- physical therapist / physiotherapist;
- occupational therapist;
- speech-language pathologist / speech and language therapist;
- audiologist;
- dietitian;
- psychologist / psychotherapist / other qualified psychological professional;
- exercise and training professional;
- qualified massage/manual practitioner where legally appropriate;
- the person;
- family and caregivers;
- assistive technology;
- home, workplace, school, community, and environmental modification.
The same person remains the shared object. Professional roles retain distinct scope, authority, and evidence requirements.
See architecture/COORDINATION_TOPOLOGY.md.
A Body Function Report is not the world model itself. It is a governed human-readable projection of the evidence-supported modeled state.
Report_t = Projection(ModelState_t, Evidence_t, Audience, Authority)
Historical reports must remain replayable and must not be silently rewritten by later evidence.
See architecture/REPORT_PROJECTION.md.
These essays explain the HFWM research program for a broader scientific and public audience. They are non-normative companions to the formal framework.

The current public HFWM framework formally specifies:
- typed whole-person state representation;
- internal/external task and Demand reasoning;
- capacity/engagement type separation;
- evidence, uncertainty, hypothesis, and judgment boundaries;
- governed next action and responsibility routing;
- feedback, reassessment, and history-preserving longitudinal update;
- human-readable state projection;
- integration with governed scientific knowledge sources.
HFWM does not currently claim:
- exhaustive whole-body simulation;
- calibrated prediction of every future human state;
- causal counterfactual simulation for arbitrary interventions;
- autonomous medical diagnosis;
- autonomous high-risk treatment selection;
- complete clinical outcome validation;
- release of the complete production reasoning system.
This repository is designed to grow over time. Future public content may include dedicated papers, public typed schemas, benchmark sets, longitudinal state research, internal-task studies, coordination models, public Functional Bridge research, reproducible non-sensitive examples, interoperability mappings, and empirical validation.
Public research growth does not imply release of proprietary production implementation.
