L2A-003,01 legal-suffix,Nestle SA,nestle.com,Nestle S.A.,nestle.com,MATCH,Full stops inside the entity suffix.
L2A-004,01 legal-suffix,Siemens AG,siemens.com,Siemens Aktiengesellschaft,siemens.com,MATCH,Abbreviated vs expanded German entity form. No English suffix list covers this.

L2A-006,01 legal-suffix,Fabrikam GmbH,fabrikam.de,Fabrikam Gesellschaft mit beschraenkter Haftung,fabrikam.de,MATCH,Expanded German entity form; the strings share only the trade name.

L2A-011,02 trade-name-dba,FedEx,fedex.com,Federal Express Corporation,fedex.com,MATCH,"Contraction, not an acronym. Edit distance is large; the domain carries the match."
L2A-012,02 trade-name-dba,IBM,ibm.com,International Business Machines Corporation,ibm.com,MATCH,Initialism. Salesforce documents an Acronym algorithm for exactly this case.
L2A-013,02 trade-name-dba,3M,3m.com,Minnesota Mining and Manufacturing Company,mmm.com,MATCH,Numeronym with no shared characters and a different corporate domain.
L2A-014,02 trade-name-dba,Alphabet,abc.xyz,Google LLC,google.com,REVIEW,Holding company vs operating company. Correct answer depends on your rollup policy.

L2A-016,03 subsidiary-hierarchy,AWS,amazon.com,"Amazon.com, Inc.",amazon.com,REVIEW,Division sharing the parent domain. Domain matching links it; policy decides if that is right.
L2A-017,03 subsidiary-hierarchy,Amazon Web Services,aws.amazon.com,"Amazon.com, Inc.",amazon.com,REVIEW,Subdomain. Tests whether the matcher reduces to the registrable domain.
L2A-018,03 subsidiary-hierarchy,LinkedIn,linkedin.com,Microsoft Corporation,microsoft.com,REVIEW,Acquired subsidiary that kept its own name and domain. No string or domain signal connects them.
L2A-019,03 subsidiary-hierarchy,GitHub,github.com,Microsoft Corporation,microsoft.com,REVIEW,"Same pattern; requires a maintained hierarchy, not a matching algorithm."

L2A-036,05 non-latin-transliteration,Ørsted,orsted.com,Orsted A/S,orsted.com,MATCH,Danish slashed O. Case folding alone does not fold it to a plain O.
L2A-037,06 free-email-domain,Acme Corporation,gmail.com,Acme Corporation,acme.com,REVIEW,"Name matches exactly, domain does not. A domain-only matcher misses it; an auto-match on a free domain is unsafe. Correct behaviour is to queue."

L2A-042,06 free-email-domain,Litware,student.university.edu,Litware BV,litware.nl,NO-MATCH,Academic domain. Domain matching against an .edu must not link to a commercial account.
L2A-043,06 free-email-domain,Acme Corp,acmeconsulting.com,Acme Corporation,acme.com,REVIEW,Different registrable domain that contains the account name as a substring. Substring domain logic produces a false positive here.

L2A-049,07 rebrand-m-and-a,Randstad UK,randstad.co.uk,Randstad N.V.,randstad.com,REVIEW,Country operating entity vs group parent. Two-part TLD is a second trap.
L2A-050,07 rebrand-m-and-a,Siemens Energy,siemens-energy.com,Siemens AG,siemens.com,NO-MATCH,Siemens Energy was spun off in 2020 and is separately listed. Both the name prefix and the domain prefix invite a false positive.
