Personal Vault #002 — The Product One thing I want to make clear early in this project: I'm not building a Jellyfin server. I'm building Personal Vault. Today Jellyfin handles media playback. Tomorrow it might be something else. If that day comes, I want to replace one component—not rebuild the entire system. That's why one of the first design principles I wrote was: Personal Vault is the product. Everything else is infrastructure. The library matters more than the player. The data matters more than the software. And every important decision goes into a Build Guide—not because I'll forget next week, but because in three years I want to rebuild the whole platform in a single afternoon. One step at a time. #PersonalVault #SelfHosting #HomeLab #Docker #Debian #DataIndepndece
