04 — Knowledge/Live
A second brain, built like software.
QuantVault is a 9,607-entry Obsidian knowledge base spanning eight domains. It's not a notes folder, it's a structured, cross-linked knowledge graph with a consistent authoring methodology, a tagged taxonomy, and a retrieval layer wired directly into Claude so it works as a live reasoning surface, not a static archive.

How it works
A knowledge graph that thinks with me.
Structured, not piled
Every entry follows a consistent schema and lives in one of eight domains: strategies, math, microstructure, risk, infrastructure, history, behavioral finance, and careers. New material is added in deliberate waves rather than dumped, so the structure stays navigable as it scales.
Cross-linked like a wiki
Entries reference each other with wiki-links, forming a real graph. Concepts that should connect, do — so following a thread surfaces the related math, the historical example, and the risk caveat together instead of in isolation.
Wired to Claude
The vault is a retrieval layer for Claude. I can ask a question and have the answer grounded in my own curated, cross-linked notes rather than generic web knowledge: the AI reasons over my structured base, and what it learns flows back in as new linked entries.
Built like production software
Authoring conventions, a tagged taxonomy, an index that loads at the start of every session, and rules for what belongs where. It's maintained with the same discipline as a codebase, which is what keeps 9,607 entries useful instead of overwhelming.
Inside the vault
What it actually looks like.
The whole graph
This is every entry and every link at once. All 9,607 notes pull into eight glowing domain clusters, and the entire knowledge base renders as a single connected constellation.
Closer in
Zoomed into the graph, each hub note radiates out to the entries that reference it, while cross-domain threads weave the separate clusters back together.
