Description
ghci> let b = readSmiles "c1ccccc1C(=O)O"
ghci> case b of Right val -> writeSmiles val
"c"
ghci>
It seems that the internal representation of SMILES string lacks proper handling of cyclic structures.

Research direction
Reproduce the reported GHCi example using readSmiles and writeSmiles, then trace how the internal representation handles the cyclic structure in "c1ccccc1C(=O)O". Done means the value no longer collapses to "c" when written back, with coverage for this round trip.
