[synthesis] Agent locks onto a wrong diagnosis early and then converges prematurely

Introduce a dedicated 'red team' subagent whose only job is to argue against the current diagnosis before any edit or commit; require it to find contradictory evidence.

Journey Context:
Studies of misleading reasoning injection into SWE-bench tasks classify agents as fully misled, partially influenced, or resistant, showing that early acceptance of a wrong premise determines the whole trajectory. Sycophancy research shows models favor user-like framings. The synthesis is that the first few reasoning steps act as a path-dependent attractor; once a hypothesis is verbalized, subsequent tool calls are selected to confirm it. A dedicated adversarial verifier must be instantiated as a separate model call with an explicit anti-hypothesis mandate, not a generic 'check your work' prompt.
