Missing component value
○ unknowndeclaration/missing-value
What it looks like
R3 has no usable resistance value — the DC solver left it open, so voltages around it are not computed.
What it checks
A component whose value can't be parsed into a number the solver can use. The part is honestly left out of the math rather than guessed.
Why it matters
A solver that guesses missing values produces confident, wrong numbers. Marking the gap 'unknown' keeps every number you DO see trustworthy — the voltages around the gap are simply not claimed.
How to fix it
Give the part its value. The moment it parses, the surrounding nodes start solving.
