The Android debug bridge's command name — the wire between a dev machine and a device, spoken lowercase in the shell.

The declared surface by which one system may address another. A promise about what may be asked and what will come back.

Able to work together without harm. Compatibility is a property of the pair, never of either alone.

Sleep that intends to wake — capability at rest, not gone; the season between uses.
