Would it be a safe assumption to describe a 'detached HEAD' state as
being synonymous with a (local) personal scratchpad or temporary
workspace based on and from the original committed object?

If this assumption is correct, then maybe this notion of a scratchpad
may be more intuitive and conceptual to new users without getting
bogged down with the necessary semantics of the terms used, but can
also preserve references to 'detached HEAD' in the documentation for a
fuller explanation.


A scratchpad or temporary workspace description alludes to its semi
permanent nature, and can warn that the subsequent commits may be lost
through aging and garbage collection until the user "commits" to
saving their progress through the creation a new branch, and thereby
making them permanent.


I must say the explanations presented in this thread have shed some
light on what is on the face of it a common trap that leaves new users
wondering "What happened to my work!" and I thank you all.
