Just curious because of the language you used. Is the data validated in the client side and reported as success there? Validation has to happen on the server. Client side stuff serves other purposes: saving pointless server hits with pre-validation, helpful UX alerting the user early in the case of invalid data, etc. JS validation is trivial to circumvent for a hacker.

Alas, the 0.01% or less of the transactions that fail leave no record of their existence in the MySQL logs, the webserver logs, or logs I create using perl.

Either you are doing all of the so called transaction in these fail cases in JS or your logging is incomplete/broken/off somewhere in the chain. By default (in most webservers) there is a record of all requests/responses whether errors or not. No record means no request was ever made/received and the failure point is pre-CGI.
