Retest objective
The retest examined whether the revised cubic Bezier construction still exposed a practical deterministic solution through the public registration interface.
Observed result
The earlier proof of concept did not transfer directly to the changed challenge. Targeted polynomial and geometric approaches were evaluated against a small, non-destructive sample and did not yield a reliable solver during the allotted test window.
Interpretation
Failure to reproduce the previous bypass is narrower than proof that the challenge is resistant to automation. The retest did not exhaust computer-vision, accessibility, outsourced-solving or high-volume strategies. Server-side abuse controls remain necessary.
