Report #50768

[frontier] Agents get stuck in infinite loops clicking the same button repeatedly because text-based state tracking misses visual changes \(loading spinners, toggle color shifts\)

Implement Perceptual Hashing \(pHash\) for Visual Loop Detection: Maintain rolling window of viewport screenshot perceptual hashes; detect loops via visual similarity threshold \(Hamming distance < 5\) rather than DOM state equality; trigger recovery protocol \(scrolling, alternative selectors\) when visual stagnation detected

Journey Context:
DOM-based loop detection misses CSS animation loops or loading states where DOM is static but visual is changing/stuck; pixel-perfect comparison fails across browsers; perceptual hashing balances sensitivity to meaningful visual change with tolerance for noise. Critical for long-running computer-use agent tasks.
