v0.2-alphaOPEN SOURCELOCAL-FIRSTHUMAN APPROVAL

VESPERA

Local-first AI Operations Kit

Building practical infrastructure for owned context and human-approved AI workflows.

Problem

AI tools fragment project memory across chats, platforms, and sessions. Agents lose context and need stronger human approval loops.

What I’m building

A local-first AI operations kit for project memory, agent coordination, and human-approved execution.

Stack

Tauri / TypeScript / Rust / Local storage / Agent workflow layer

DEPTH 04/THE DIGGING PATH

From physical discipline to system discipline.

Sports science taught me repetition and execution. AI taught me pattern recognition. Web3 taught me ownership and verification. Now I build tools for trust, autonomy, and practical user-owned systems.

Trench Club

A public builder lab by SAPGUN.

I dig into Web3 trust, sovereign AI, and ownership-driven products - building prototypes, documenting experiments, and examining the systems shaping the next internet.

Builds show what I make.
Field Notes show what I learn.
Research Digs show how I think.
Signals show what I am watching now.

Keep digging.
Build what can be verified.
