Disallow '.' components and path separators in GetScpFileName so malicious SCP clients cannot escape the configured base directory.
Call wolfSSH_CleanPath on the client-supplied base path before ParseBasePathHelper so directory probing happens on canonicalised paths.
Treat *sigSz as the caller-provided capacity, raise WS_BUFFER_E if the agent response is larger, and clear the size on failure to avoid buffer overruns.
Track the last agent message id, reject non-signature replies, reset the failure flag, and ensure the agent write completes before trusting the returned signature.
Exercise agent write failures, non-signature responses, oversized signatures, and the happy path to cover the recent wolfSSH_AGENT_SignRequest hardening.
Instantiate a wolfSSH_AGENT_CTX before invoking wolfSSH_AGENT_SignRequest so the regression tests exercise the intended paths instead of failing with WS_AGENT_NULL_E.
