[synthesis] Agent enters infinite patch loops trying to fix failing tests, breaking passing tests, masking fundamental architectural flaws

Implement an iteration budget with a 'complexity threshold'; if test pass rate oscillates without reaching 100% in N steps, force a full revert and architectural re-plan.

Journey Context:
When an agent achieves 3/5 tests passing, it greedily tries to patch the 2 failures. This often breaks the 3 passing tests. The agent chases the gradient of local test pass rates, iterating endlessly \(2/5 -> 4/5 -> 1/5\) without realizing the initial approach is fundamentally broken. The synthesis: Greedy test-driven patching is a local minima trap. Partial success hides the root cause, and without a reset mechanism, the agent will loop until context exhaustion, conflating 'making progress' with 'fixing the architecture'.
