21 · Field Notes#
"Not a polished deep-dive; raw reality lived through and jotted down in production."
This section is a different content class from the numbered deep-dives: raw commands, configuration and installation guides left over from real setups. They were deliberately not forced into deep-dive anatomy (epigraph → concept table → anti-pattern → checklist) — their value lies in being "working / having-worked as-is". Adapt them to your own environment and use them.
⚠️ The IP/password/domain values here are examples and must be read with placeholder logic. Never copy your own secrets directly.
