Description

Is it possible to implement compact encoding for signed integer?
Should be very similar to unsigned, except storing the signing bit differently.

Research direction

Start by locating the existing unsigned compact encoding and decoding implementation and its tests. Compare the requested signed behavior with that path and clarify how the sign bit should be represented. Done should include signed values encoding and decoding correctly, with coverage for representative positive, negative, and boundary values.
