[synthesis] Compounding logical errors masked by passing static analysis tool calls

Require end-to-end execution or behavioral testing as the primary verification gate, not just syntax/linting tools; treat static analysis passing as a necessary but insufficient condition.

Journey Context:
Agents often use linters or compilers as their primary 'verification' tool. When the tool returns '0 errors,' the LLM interprets this as 'the code is correct' and moves on. This partial success masks total logical failure. The agent then writes subsequent code based on the flawed logic, creating a cascade of compounding errors. The tradeoff is that end-to-end tests are slower and harder to set up than linters, but relying on syntax validation for logical correctness is a fundamental category error. The agent's plan must mandate behavioral validation.
