VAULTREAVE

Descend. Take the loot. Extract.

VAULTREAVE is a 2D pixel dungeon game built around the decision to keep exploring or extract. Choose a class, fight and collect loot in a changing dungeon, then decide when the risk is worth taking. It runs directly in the browser with no download.

02AI · LONG-TERM CONTEXT

Aethmere Shízhòu

Let long-running work continue.

Aethmere is a personal context system for long-running AI collaboration. It helps people manage goals, project material, and important decisions so work across devices and tasks does not repeatedly start from zero.

RESEARCH PROJECTS

Turn long-term questions into engineering work.

Alongside product development, we study how mathematical knowledge can be organized reliably and how individuals can regain control of their attention. Each project states its goals, method, and limits without presenting ongoing exploration as a finished result.

01KNOWLEDGE ENGINEERING · MATHEMATICS

Mathematical theorem knowledge engineering

Make theorems, sources, and verification status traceable.

A long-term engineering project for mathematical knowledge. Stable identities, dependency links, source records, and formal proof tools show what each statement is, what it depends on, and how far it has been verified.

Ongoing research · Initial specification and catalog established

Research boundaryCatalog inclusion does not replace proof, and numerical experiments are not presented as established theorems.

02HUMAN-CENTERED SYSTEMS · ATTENTION

QuietList

Return content choices to the user.

A personal attention-infrastructure project that studies how public content can be analyzed with user permission. Evidence-based, explainable, and reversible rules help people label, fold, or hide low-value material. The goal is to save attention, not extend time on site.

Research boundaryThe project does not score people or personalities and does not build a centralized web-wide blacklist.

HOW WE BUILD

Take the experience seriously. State the limits clearly.

01

Experience is the first acceptance test

From the feedback of an attack in a game to the clarity of an answer, a feature is complete only when people can genuinely experience it.

02

Prefer long-term value

We care whether products can stay useful and continue to evolve, giving content, systems, and worlds a durable life.

03

Be explicit about capability boundaries

Usable versions, reviewable evidence, and clear project status show what has been achieved and what remains under study.
