Comparison scope
The retest revisited the registration challenge, honeypot handling and selected request-validation paths that had been discussed in the earlier assessments. Testing was constrained to the deployment state and access available on the stated date.
Confirmed changes
The original challenge solver did not reproduce against the revised geometry, and the tested form flow included randomized honeypot behavior. Selected duplicate-request cases were also rejected in the observed single-session path.
Unverified properties
The retest did not establish durable replay protection across multiple processes or restarts, resistance to all automated solving methods, or the security of unrelated application functions. It therefore records observed improvements without assigning a production-readiness verdict.
