Experiments & cultural artefacts
Lab
Before the Institute, there was the Random Research Lab — a quieter name for the same instinct: that the goddess Τύχη, fortune and chance, sits at the root of cryptography and that the work most worth doing sometimes starts in a corner with a notebook rather than on the front page. The Lab is where that instinct still lives.
For peer-reviewable working papers and formal research output, see Research. This page collects the lab side: experiments, essays, and publications adjacent to the Institute's technical mission. The conformance and measurement instruments — verifier parity, negative test corpora, daily trust-infrastructure measurement — live under Tyche Labs.

microGPT 3D Tutorial
A trilingual, browser-side 3D walkthrough of Karpathy's ~150-line microGPT — a complete GPT small enough that nothing is hand-waved: live attention beams, gradients flowing backward through a draggable graph, and a temperature slider on real generation. Adapted for junior AI researchers, with a foundations primer and glossary. Based on microgpt-3d-tutorial by lxb12123 (MIT).

Bayesian Knowledge Tracing Study Guide
A trilingual, interactive guide to Bayesian Knowledge Tracing, adaptive task selection, explainability, and classroom heatmaps — a safer flagship case for attestable educational AI where teachers remain in control and recommendations can leave replayable evidence.

PKI-ZEN
A trilingual sūtra about certificates, YAML, and almost-enlightenment — a cultural companion to Tyche's technical work on trust infrastructure.

H2O Atlas
A probabilistic risk estimator for Estonian water-quality compliance, built on Terviseamet open data. It originated as a TalTech Masinõpe (spring 2026) coursework project and continues as a Tyche-side testbed for EATF — a transparency tool, not a health advisory.

Accountable Agentic Action — the whole architecture
The full picture on one page: an autonomous agent acting under a machine-readable mandate carried in the EU Digital Identity Wallet, a four-layer verifier that stops it before any effect, hardware-attested evidence, and the four-box accountability chain — layer by layer, with origin and maturity called out, on the EATF framework.

Break the verifier
Edit a signed Action Evidence Package in your browser and run the reference verifier on it — the same ordered checks as the Python original, with real SHA-256 and Ed25519 via Web Crypto. Try to make it say ALLOW for an action the mandate never authorised; you cannot, without the keys, and that is the lesson. The in-browser verifier is parity-tested against verify.py on every sample and attack, as a build gate.
interactive demo · EUDI wallet · mandate enforcement
The agent that cannot overspend
An AI assistant is handed a wallet and a signed permission slip — pay invoices to one supplier, up to a €500 cap — while a verifier makes it physically unable to overspend, be scammed, or have a payment tampered with. Walk the four gates every payment must pass, in plain language.
interactive graph · measured daily · trusted-list observatory
The Map of Published Trust
Every state that runs a trust framework publishes a list saying whom it vouches for, and the European Union publishes a list of those lists. This is the shape of the whole thing, fetched rather than described: two regional hubs with no edge between them, a scattering of lists nobody points at, and the pointers that do not answer a strict client. One national list has failed every observation in the series; four copies of one regional list are served today and three of them lapsed in May.
interactive graph · EU digital acquis · NOMOS observatory
The EU Digital Acquis as One Graph
eIDAS 2.0, the AI Act, GDPR, implementing acts, ETSI/CEN standards and the EUDI architecture framework rendered as segment-addressable nodes with typed cross-corpus edges and a coverage-honest gaps lens. This is the public tier-0 teaser; the row-level evidence layer is withheld pending peer review.
talk · draft slides · agentic-AI evidence
Who Said the Agent Could Do That?
A talk on catching correctly-signed but out-of-mandate AI-agent actions, built around the public MIT-licensed aep-sandbox: an action whose every signature verifies is still rejected when it exceeds the mandate it was granted. Draft slides, submitted to Disobey 2027.
diagram · attestable agency
From presence to authority
Four rungs of machine-checkable legitimacy — bot-detection, hardware tokens, agent-legitimacy schemes, and per-action evidence — and why, once agents act on their own, the question worth defending climbs from "is there a human?" to "what did it do, under whose authority, in mandate?"
daily instrument · EUDI trust hub · NOMOS observatory
The Six Lists
The EUDI Wallet trust hub carries six "Lists of trusted entities". A scheduled probe asks the hub's own interface once a day whether each list is published yet, and keeps every answer — so the day the registers begin to fill is on the record. Includes the countdown to 24 December 2026, when relying-party registers must expose a public API.

Posters and dated snapshots
Poster-format material and dated measurement snapshots from the same research lines. Snapshots record what was verifiably true on the stated day; the registers and schemes they describe are expected to change.

- The certification asymmetry — eIDAS 2.0, measured 5 Aug 2026 → Where Regulation (EU) 2024/1183 places assurance and where it does not: certified wallets, registered relying parties, and the state of six trust-hub lists on the measurement day.

Simulations
Public model sandboxes
These are exploratory synthetic simulations for asking better questions, not prediction engines or policy advice. They expose assumptions, scenario branches, and country-level sensitivity so a reader can see how conclusions change when parameters move.
synthetic wellbeing simulation · country replay · AI futures
Happy Scenario Atlas
An interactive explorer for Tyche's synthetic wellbeing simulations. It lets readers replay country, regional, and world-level scenarios for human flourishing and agentic-AI futures, using filters for harm risk, fragility, and modeled suffering effects.
The public build is refreshed from the institute's long-running simulation experiments, so the atlas can absorb new scenario evidence as the work continues.
Emerging research labs
New lines under formation
These labs are early-stage research programmes rather than finished publications. They name the questions Tyche is beginning to organize into source maps, datasets, and future papers.
public evidence lab · CEN/CENELEC · AI Act · multilingual standards
NORMTRACE — Standards Assurance as Join Integrity
An interactive, metadata-only lab that follows an AI Act duty through an exact CEN/CENELEC project state, dependency graph, required evidence object, human disposition, and signed, externally timestamped checkpoint.
Published v0.3.1 with a 12-body multilingual portal panel, a seven-chain AI-assurance spine, controlled LLM diagnostics, explicit missingness, and Zenodo DOI 10.5281/zenodo.21924089. It excludes standards full text and makes no conformity or semantic-truth claim.
interactive lab · RIPE Atlas · agent authority
From Permit to Packet
A breakable observatory for the full chain from a signed AI-agent mandate to an external RIPE Atlas effect, captured evidence, and a bounded public claim.
Published v0.1.0: 21 matched positive/negative pairs plus one clean baseline, 448 generated variations, a precommitted eight-measurement RIPE Atlas pilot, public GitHub verification, and Zenodo DOI 10.5281/zenodo.21923744.
public lab · X-Road · carrier-bound AI evidence
X-Road AI Evidence Lab
A reproducible lab on carrier-bound AI evidence: whether governed data-exchange infrastructure such as X-Road can carry and witness independently verifiable evidence about AI-agent actions.
The first public bundle is deposited on Zenodo. The next phase follows X-Road 8's shift toward dataspaces, verifiable credentials, cloud deployment, monitoring, and metrics.
emerging lab · literature maps · dataset provenance
Literature + Dataset Evidence Lab
A curation line for turning thesis-scale crawling into publication-grade source packs: literature, datasets, proceedings, standards, regulatory material, source quality, reuse constraints, and citation readiness.
The first internal milestone is a source-family taxonomy and a dataset inventory with license, provenance, update cadence, and paper relevance.
emerging lab · AI governance readiness · Estonia-first
PALLAS — Country AI-Readiness Lab
A country-comparison line for AI-readiness as evidence infrastructure: legal basis, competent authorities, sandboxes, standards participation, algorithm registers, digital identity, PKI, cybersecurity, procurement, and auditability.
The first worked case is Estonia, followed by a Europe-first and then global comparison.
