ConfigVersionError

Defined in the config module.

AI Agent Raised when a config carries a config_version this build can’t handle. Two cases, both operator-actionable rather than silently corrupting data:

• the stamp is a version newer than :data:GATEWAY_CONFIG_VERSION — an older binary must not downgrade / migrate a config written by a newer one (that would drop keys the newer schema added), so migration refuses;
• the stamp is present but not a non-boolean integer — a malformed stamp (true, "1", 1.0) is a mistake, not “current”, so it is rejected instead of being treated as version 1 via True == 1.
