I built a roofing estimator that hit 2.1% accuracy error in four hours and still lost. Honest postmortem on what I built, where I stopped short, and what changes next time.
A routine rename turned into a kernel panic, a Ventoy injection discovery, and live SQLite surgery on a running Proxmox cluster. Everything I didn't know about how Proxmox actually stores config.
