Report #75903

[synthesis] Agent persists with a flawed strategy because partial success in early steps masks a fundamental architectural conflict in later steps

Require the agent to generate a 'pre-mortem' dependency graph before execution. If a step fails, force a reflection step that evaluates whether the successful prior steps created the conditions for the current failure, rather than just debugging the failing step in isolation.

Journey Context:
When an agent fails at step 4, the default behavior is to analyze step 4's error. But in coding, step 4 often fails because step 2 created a schema or state that makes step 4 impossible. The agent sees steps 1-3 as 'passed' in its memory, giving it false confidence in its premise. By forcing a dependency graph pre-mortem, the agent must explicitly state 'Step 4 depends on Step 2 outputting X,' so when Step 4 fails, it checks Step 2's actual output against the dependency, catching the root cause rather than endlessly tweaking Step 4.
