there must be an accessible junction box (hence the name) of some sort.

no alternative except to pull both cable segments out of the wall
and replace with single segment.

Greetings,

What is the best (cheapest/quickest?) NEC compliant way to join two
wires within a wall that will NOT later be accessible without
disturbing the building finish?

The current method I most often see utilized in past construction is to
strip an area of insulation off of a wire without cutting it, twist
another wire around this wire with many loops and finally apply
electrical tape generously.

Thanks,
William
