01
Keep the path observable
A reliable system is easier to trust when each boundary can be checked independently. Small, explicit checks usually outlast clever recovery logic.
FIELD NOTES
Useful things deserve a quiet place.
Short notes on systems, reading, and the patient work of making complicated things understandable.
02
Prefer reversible changes
Backups matter, but a change is safest when its previous state remains understandable and the return path has already been tested.
03
Write down the boring details
Ports, versions, fingerprints, and ownership rules feel ordinary until the day they are the only clues that still tell the truth.
