[synthesis] Agent continues down a failing approach because it has already invested multiple steps in it, digging deeper with increasingly creative fixes instead of pivoting

Implement a pivot budget: if the agent hasn't made verifiable progress after N steps on the current approach, force a hard reset — clear the recent context, re-read the original requirements, and start a fresh approach. Track verifiable progress as concrete state changes \(files modified, tests passing\), not reasoning steps or attempted fixes.

Journey Context:
Agents exhibit a computational form of sunk-cost fallacy: after 5 steps trying approach A, they're reluctant to abandon it even when errors accumulate. Instead, they try increasingly creative fixes within approach A \('maybe if I also modify this other file', 'maybe if I change the import order'\), digging deeper into a wrong path. This mirrors human developer behavior but is worse because: \(1\) agents don't experience frustration that would trigger a natural pivot, \(2\) each fix attempt adds context that further commits to the approach by making the wrong path more elaborated, \(3\) there's no external voice saying 'try something different.' The synthesis combines: \(1\) AutoGPT's well-documented infinite loop problem where agents repeat failing approaches, \(2\) cognitive science research on escalation of commitment, \(3\) the observation from agent traces that failed approaches get longer and more convoluted rather than being abandoned. The pivot budget is a hard structural constraint that overrides the agent's natural tendency to double down.
