This is technical debt as horror story. The real cost of "it works, don't touch it" isn't just maintenance. It's the slow decay of institutional knowledge. No one remembers the TNSNAMES.ora syntax. No one knows why the connection uses PROTOCOL=TCPS but with a self-signed RSA key from 2001. The original developer left two jobs ago. The documentation is a printed binder, coffee-stained and missing page 47.

Open a command prompt:
