# Obsidian

## What it is

Obsidian is the knowledge management application used to browse and edit this vault. It renders the wiki-vault as an interconnected graph of Markdown notes, resolving `[[wikilinks]]` into navigable links. This vault (`wiki-vault`) is an Obsidian vault — the file structure, frontmatter conventions, and wikilink syntax are all Obsidian-native. The homelab MCP server writes new session notes and project plans directly into the vault in Obsidian-compatible format.

## Current state

Active. The wiki-vault was migrated from `pbs-projects` and `homelab-projects` in May 2026 into this unified vault. The compile loop (wiki-maintenance skill) generates and maintains the Wiki/ layer. The MCP server at `mcp.herbylab.dev` writes directly to `Sources/` using Obsidian-compatible Markdown. The email-to-vault pipeline (Gmail → n8n → Gitea → vault) also writes to `Sources/`.

## Where it lives

- App: installed on herbydev (and likely Travis's personal machine)
- Vault: `/opt/projects/wiki-vault` on herbydev
- Git-backed: vault is a git repo, changes committed via git
- MCP server writes via Gitea/git push to vault repo
