A backslash-escaped delimiter is treated as a field boundary.
Case contract
Parse one comma-delimited row with backslash escaping and no quote semantics.
Why this case matters
A local executable model for consumers of structured text; oracle values are authored literals, not outputs copied from the repaired implementation.
One recorded failure
