+# Obsidian App and SilverBullet
+
+## Architecture
+
+```
+.27 (NixOS desktop, sometimes off)
+  Obsidian native + Nvim + obsidian.nvim
+  Vault: ~/obsidian/
+  GitHub Sync plugin → syncinterval: 15 min
+
+.35 (Ubuntu, always on)
+  Gitea — central git repo
+  SilverBullet Docker — web access on proxy network
+  Caddy → silverbullet.lab.audasmedia.com.au
+```
+
+## Sync
+
+Single Gitea repo (`obsidian-vault`) on .35. Both .27 Obsidian (GitHub Sync plugin) and .35 SilverBullet (cron script) push/pull every 15 minutes. No conflicts — single user.
