• Consider making MaxPublicKeyRetriesBackoffSeconds a Setting[time.Duration] (like the other timeout/backoff fields) rather than Setting[int] with a custom unit tag. This keeps units consistent ("s") and prevents ambiguity about whether the value is seconds vs. some other duration base.

	InsecureSkipTLSVerify             Setting[bool]
	EnclaveRefreshInterval            Setting[time.Duration]
	MaxPublicKeyRetries               Setting[int] `unit:"{attempt}"`
	MaxPublicKeyRetriesBackoffSeconds Setting[int] `unit:"{second}"`
	PublicKeyCache                    ccPublicKeyCache
	Session                           ccSession
