Report #87355

[synthesis] Agent silently derails without throwing an error because it spends all iterations trying to fix a broken approach, eventually exhausting its step limit and returning a useless result.

Implement a strategy pivot threshold. If the agent fails to change the error output after 2-3 identical attempts, force a context clear of the failed attempts and inject a prompt to try an alternative approach.

Journey Context:
Agents exhibit algorithmic sunk cost. Because the context window is filled with the failing approach, the attention mechanism keeps predicting the same class of solutions. The agent makes micro-adjustments that never address the root cause. Without an external mechanism to detect stuckness \(repeated state \+ repeated action\), the agent optimizes a local minimum until it runs out of steps.
