What is Lighthouse

Weights see. Substrate knows. Baselines personalize. Policy decides how much to say.

The platform reads the body through several specialized modules — “hands” — for movement, tongue, nutrition, hydration, metabolism, body maps and, next, vision and jaw. A central brain connects what the fingers find. The temptation in 2026 is to hand all of this to a large AI model. This page is an overview of where our research has led, and it happens to argue the opposite.

Almost everything that makes the platform valuable — practitioner knowledge, compensation maps, the relationships between body systems, the rules for how cautiously to speak — is substrate: written, readable, citable knowledge. Learned model parameters — weights — are needed in only one place: turning camera pixels into measurements. Between the two sits a layer that makes the platform personal: each person’s own baseline, fitted from their captures over time. Language models are kept at the edge, as assistants that may suggest but never decide.

Three kinds of computation

“AI” is used loosely for three very different tools

Each has a job it is good at and a cost it carries.

Automation

Rules, formulas and lookups that someone wrote down.

Use when the right answer can be written down in advance.

COST · AUDITInstant and free. Every step readable.

Machine learning

Parameters learned from many labelled examples.

Use when the input is raw signal — pixels, video — or there are thousands of labelled outcomes.

COST · AUDITFree on device once trained. Testable, not readable.

Language AI

A pre-trained model that reads and writes text.

Use when the input is unstructured text and something else checks the output.

COST · AUDITSeconds to minutes, or paid per call. Neither readable nor reliable on its own.

Our rule of thumb. If you can write the test with an exact expected answer, it should be a script. A language model never judges another model — the referee is always a script.

Ontology

A shared vocabulary for what the system reasons about

The more research a person does in the medical field, the more they see an intentional separation of vocabulary for things that can’t be argued apart: the same, or at least intimately connected and synergistic.

Diagram: a person makes a capture, which yields an observation; measurements computed from it are compared with the person's baseline and emit codes; codes trigger links that cite sources; links are asserted as correlations, which feed a decision shaped by policy; model-proposed correlations become memories, and a reviewer's acceptance turns them into links.
Every term in the diagram exists in code today.

The epistemic layer

How the system knows what it knows, and how sure it may sound

To account for bias we work at the level of epistemics. Health and wellness is a field where well-evidenced practitioner observation is often absent from mainstream sources; the platform must neither suppress it nor overstate it.

Responsibilities & research protocol

What we follow, and require of anyone who uses our services

These are the questions we take to regulatory counsel and an ethics board. The answers below are ours, not theirs.

Claims

Staying a general-wellness product depends on never claiming to diagnose, treat or prevent a condition — in the app, in marketing and in model output.

Research ethics

Collecting people’s data to establish or validate correlations is human subjects research: informed consent, and ethics review to publish or partner with clinics.

Health data

HIPAA if you are or serve a covered entity; consumer health-data and breach rules regardless. Encryption, access control and retention are yours to get right.

Measurement validity

Show measurements match ground truth, repeat reliably, and that practitioners agree on what they label.

Knowledge provenance

Keep practitioner observation labelled as such — distinct from clinical evidence — everywhere it surfaces.

Food · Nutrition policy

White paper draft v1.01 · Not peer reviewed

Dense energy isn’t usable energy

From the manuscript Destroying Food Myths and the white paper Reevaluating Nutritional Policy Through Molecular, Ecological, and Institutional Lenses.

4 of 27vitamins and minerals with a Daily Value that a US label must list
−84%magnesium in white flour vs whole grain; enrichment doesn’t put it back

  • Calories measure how much energy a food holds, not how much the body can use. Usable energy runs on micronutrients.
  • Public frameworks — calories, PDCAAS, the food pyramid — were built under constraints that no longer hold, and neglect gene–nutrient interactions, trace minerals and the microbiome.
  • People aren’t all the same, and neither are soil, water or access. Guidance should measure, not assume.

Skin & hair · Personal care

Research notes · Not peer reviewed

The other aisle

The findings that get discussed as a diet story apply to what goes on skin and hair — and that part is rarely said out loud.

  • Industry shaping what the public hears is a familiar story in nutrition. The same pattern has played out in personal care, told as one-off product scandals rather than a pattern.
  • Absorption is discussed in terms of digestion. The same measurements exist for skin.
  • Who funds ingredient safety data, and how long findings take to surface, matters as much on the shelf as on the plate.

Superior Terminus Framework

Movement assessment, fascial chain correspondence, and the case for multi-terminal triangulation body assessments. An independent evidence synthesis by Joshua Harris, published 17 September 2026 (CC BY-NC 4.0).

doi:10.5281/zenodo.22805743 ↗

  • Three terminals — the feet, the spinal column and the tongue — read at the same moment and in the same position produce a pattern none of them surfaces alone. “The claim is triangulation, not direct correspondence.”
  • The tongue is the superior terminus of the deep front line and one of the five diaphragms of the osteopathic model. Oral assessment is non-invasive and readable anywhere.
  • Non-athletes spend most of the day seated or reclined, yet assessment treats upright posture as the functional baseline. Position is the missing modifier.

Status: technically feasible, not yet executed. Assessment protocols are at the pattern-surfacing stage; inter-rater reliability has not been established.

Currant · The food research in an app

Everything a label leaves out, in one scan

Scan any product

Point your camera at a barcode, or search millions of foods by name.

Nutrition Score, 0 to 100

How whole, fibrous, hydrating and clean a food is. The same score for everyone, whatever your goal.

Quick vs lasting energy

Whether a food hits fast or carries you for hours, scored separately so goals never bend the quality score.

Harmful additives flagged

A carcinogen or harmful additive caps the score, instead of being averaged away.

Better alternatives

When a product scores low, Currant shows similar products that score higher.

Recalls and allergen watch

Food recalls, and the allergens you choose to watch for.

Most food apps count. Currant measures.
