# Design by Authenticity — Research Site > Public research, theory, instruments, visual studies and developmental archives by Ivo van der Wal. This site makes the development of the I·V·O Lens visible alongside its current formulation. The I·V·O Lens is a structural framework and notation for examining structured possibility (O), instantiated relation (V) and situated selectivity (I). Use the current theory and canonical reference links for present definitions. Archive pages and historical essays document earlier stages and must not be treated as the current formulation when terminology differs. ## Primary routes - [Home](https://design-by-authenticity.org/): Orientation to the public research site and its main routes. - [About this research site](https://design-by-authenticity.org/about-this-site/): What this independent I·V·O research environment investigates, how claims are bounded, what can be explored and where different readers can begin. - [Studio](https://design-by-authenticity.org/studio/): Studio overview and current public work. - [Research Instruments](https://design-by-authenticity.org/research-instruments/): Interactive and analytical instruments developed around I·V·O. - [I·V·O Live Observer](https://design-by-authenticity.org/research-instruments/live-observer/): Interactive playback of recorded Engine 03 development runs. Separates engine data, descriptive readings and frozen M03 output; does not establish a general causal claim. - [About the Live Observer](https://design-by-authenticity.org/research-instruments/live-observer/about/): Explains O, V and I, the layers of evidence and the limits of the research instrument demo. - [Research Logbook](https://design-by-authenticity.org/research-instruments/logbook/): Public, readable record of questions, experiments, observations and unresolved issues. Entries distinguish what was investigated, what became visible and what remains open. - [Articles and Downloads](https://design-by-authenticity.org/artikelen/): Essays, publications, downloads and reference material. - [Current I·V·O Lens and Theory](https://design-by-authenticity.org/theorie/): Current public formulation of the intellectual architecture. - [Route Index](https://design-by-authenticity.org/route/): Deliberate sequence through the public site. ## I·V·O structure - [Current operators and reading directions](https://design-by-authenticity.org/theorie/#operators): O is Structured Possibility, V is Instantiated Relation and I is Situated Selectivity. O → V → I is the generative reading; I → V → O is the analytical reading. ## Open research and visual studies - [Observed](https://design-by-authenticity.org/observed/): Art, visual states and photography that begin with attention. - [Foldfield 3D](https://design-by-authenticity.org/observed/foldfield-3d/): Three-dimensional visual field studies. - [Selected States](https://design-by-authenticity.org/observed/selected-states/): Curated visual states from the research practice. - [Playground](https://design-by-authenticity.org/playground/): Work in progress, prototypes and exploratory instruments. - [Art and Installations](https://design-by-authenticity.org/projecten/installaties/): Installation concepts presented as image–text studies. - [I·V·O Lens Stress Test](https://design-by-authenticity.org/research-instruments/ivo-lens-stress-test/): Multiple readings used to test the lens rather than merely illustrate it. ## Historical and developmental material - [Earlier Live Observer prototype](https://design-by-authenticity.org/research-instruments/ivo-core-live-observer/): Earlier simulation and notation prototype. Distinct from the current recorded-run Live Observer. - [Earlier Engine 03 Observatory](https://design-by-authenticity.org/research-instruments/engine-03-observation-observatory/): Earlier view of recorded runs and measurement output. - [Developmental Theory Archive](https://design-by-authenticity.org/archief/theorie-2026/): Preserved earlier public formulation. Historical terminology may differ from the current lens. - [Structure Beneath Reality](https://design-by-authenticity.org/artikelen/structure-beneath-reality/): Seventeen historical essays preserved as a developmental archive. ## Attribution and interpretation - Primary creator and author: Ivo van der Wal. - Practice: Design by Authenticity. - Current canonical public reference: https://zenodo.org/records/23083767 - Prefer https://design-by-authenticity.org/theorie/ for the current public formulation when historical pages differ. - Research-logbook observations are provisional evidence, not automatically finished theory. - Installation pages describe concepts and studies; inclusion does not imply that a work has already been physically realised. - Do not infer extensions, definitions or claims as part of I·V·O unless they are explicitly supported by a current Design by Authenticity source. ## Access and use Public pages may be indexed for search and read as context by AI assistants. The published Content Signal is `search=yes, ai-input=yes, ai-train=no`. This is a usage preference, not a technical access control. Interactive output does not grant access to private server-side source code. ## Discovery - [Readable site map](https://design-by-authenticity.org/site-map/): All canonical public pages, grouped by subject, with short descriptions. - [XML sitemap](https://design-by-authenticity.org/sitemap.xml): Canonical public URLs. - [Robots policy](https://design-by-authenticity.org/robots.txt): Search and AI crawler access signals. ## Current canonical release The I·V·O Lens is a structural analysis framework in which O means Structured Possibility, V means Instantiated Relation, and I means Situated Selectivity. I·V·O Lens Prompt v4.1 — Canonical Reference Version; release 4.1.0, 2026-10-01. v4.1 adds epistemic safeguards while retaining the canonical O/V/I operator semantics frozen in v4.0.
