Tiago Deretti's working notebook for systems, resilience, and the human side of technical work.
This is the personal archive. Essays, working thoughts, project references, and a record of ideas across infrastructure, resilience, memory, history, philosophy, creative work, and the human side of complex systems.

Deretti Cyber Labs is the formal research and framework property. This site is quieter and more personal: a notebook, archive, reading map, and index of related work.
