RESOURCES · GROUND_TRUTH™
A deep-dive of research into Bio_Sole.
Our site pages are written to be read by anyone. These papers are written to be checked. Each one takes a single question, sets out the method behind our answer, names the limits, and sources every figure. If you need to verify what we say rather than take it on trust, start here.
What every paper carries.
i · NAMED AUTHORS
Signed by the person who did the work.
Every paper carries an author, a role and a date. Nobody publishes anonymously here, because a paper nobody will put their name to is not a position, it is a brochure.
ii · FREE TO READ
No form, no gate, no email required.
Every paper's abstract and findings are on the page, and the PDF downloads without asking you for anything. A document you have to trade your contact details for is marketing; we would rather you read it and decide.
iii · VERSIONED AND DATED
When a paper changes, we say what changed.
Each revision carries a version, a date and one sentence naming what moved. There is no silent edit, so a reader who quoted the old wording can see exactly why it is no longer the wording.
Five papers, one argument.
Three set out how the measurement is made and checked. Two set out what it changes for the people on the other side of it. All five carry the same restraints. The first is out and free to read; the other four are being written, and each says so.
01 · Regulatory
The Ground_Truth™ Standard: what we will not claim, and why we published it anyway
The public edition of the standard we wrote before we built the product: the four things a measurement must carry, and the claims we rule out.
02 · Engineering & AI
Auditable by design: what a replayable AI pipeline actually requires
Time-native architecture, complete model version control, and the three tests every model passes before it runs. Written for people who have to sign off on an AI system.
03 · Insurance
Identity as the root control: why every other control inherits day one
How one-and-done underwriting, credential sharing and account takeover trace back to a single decision, and what continuous verification changes without adding data liability.
04 · Engineering & AI
Why the sole: measuring movement outside the lab
Five decades of optical motion capture, the shift to wearable sensors, and why the one place the whole body meets the ground is where a stride reads most naturally.
05 · Wellness practitioners
When effort goes unrecorded: the gap between what a client did and what the plan assumed
What happens to a client's own account of their week when nothing records it, and what a record they control changes for the practitioner and the file.
Every paper in the series carries the same three sections, in the same order: what we claim and the evidence we hold for it, what we refuse to claim, and how far along the work honestly is. A card with no link is a paper still being written - the title and the subject are settled, the paper is not.
Questions people ask us
Do I have to give you my details to read a paper?
No. Every published paper's abstract and key findings are on its own page, and the PDF downloads without a form, a gate or an email address. One of the five is out so far; the other four list here with what they will cover, and each gets its page when it is written.
What is in a Bio_Sole whitepaper?
Three sections, in the same order every time: what we claim and the evidence held for it, what we refuse to claim, and how far along the work honestly is. Every paper is signed by a named author with a version and a date, and the restraints are stated as conditions on the argument rather than as a disclaimer at the end.
Do the papers make health claims?
No. Bio_Sole does not diagnose, treat or predict disease, and no named condition appears in connection with the product in any paper. The papers describe movement and flag a change from a person's own baseline: deviation, not diagnosis.
What will you not claim in any of them?
Four things, and they are conditions on what a paper may argue rather than disclaimers at the end. No clinical conclusion: no diagnosis, treatment or prediction of disease, and no named condition in connection with the product. No certification we have not finished earning: certifiable describes a design, certified describes a completed process. No figure we cannot source. And no claim that our measurements show objective reality - every instrument gives an estimate with an error attached, ours included.
What is Ground_Truth™?
Ground_Truth™ is Bio_Sole's name for a measurement that can account for itself: an observation bound at the moment of capture to a verified identity, an instrument, a timestamp and a condition, so that it can be audited rather than assumed. It does not mean the measurement is right. It means it is checkable.
Why publish a standard at all?
Because a standard nobody outside the company can read is just a preference. Publishing costs Bio_Sole the freedom to say whatever suits it later, which is the point: it gives a reader something to hold the company to that does not depend on trusting it first.
Are the papers peer reviewed?
They are internal position papers, reviewed inside Bio_Sole before release, not journal articles and not peer-reviewed literature. Where a paper cites outside work, it cites the source so a reader can go and check it.
How will I know if a paper has changed?
Every paper carries a version and a date, and a revised paper carries one sentence naming what changed. Bio_Sole does not edit a published paper silently, so a reader who quoted an earlier version can see why the wording moved.
Who should I contact about a paper?
Use the form on this page. If a paper is out, read it first - it is free and it is on the page. The form is for the question the paper does not answer, or for the paper that does not exist yet, and it reaches the person who owns that subject.
Ask us for the one that does not exist yet.
If you need something we have not written - a deeper answer, a methodology note, a question this list does not cover - tell us what it is. We would rather write it than have you guess.
Tell us what is missing.
The papers that are out are free to read on this page. If the answer you need is not in one of them - a deeper method note, a figure sourced differently, a question this series has not reached - say what it is and who you are.
