Module db2 

IBM Db2 server implementation (DRDA wire protocol).

Speaks enough DRDA/DDM that a Db2 client can complete the connection handshake (EXCSAT/ACCSEC/SECCHK/ACCRDB) and execute a basic statement (EXCSQLIMM), with the LLM playing the database: it decides whether a login is accepted and what SQLCA a statement produces. The wire codec is drda; no storage exists — the model answers every request.

Fail closed. An LLM outage during the security check is a refusal (SECCHKRM at severity ERROR), never an accept; a failure during a statement is an error SQLCARD, never a success. See AGENTS.md for what DRDA is and is not implemented here; Apache Derby’s JDBC driver and IBM’s CLI driver both connect to it (tests/server/db2/real_client_test.rs).
