Aromatic bond tags are inferred from atom flags · case 03

Aromatic bond tags are inferred from atom flags.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Return the explicit bond aromatic boolean unchanged. Atom aromatic flags are independent annotations and are never used to infer or override it.

Why this case matters

Controlled molecular graph interchange model; tests isolate atom or bond representation errors without claiming chemical validity or production toolkit equivalence.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
bridge between annotated atoms	`true`	`false`	Failed
