[research] Generating code that looks syntactically correct and runs but implements subtly flawed algorithmic logic

Mandate dynamic execution grounding: require the agent to write and execute unit tests \(including edge cases\) in a sandbox before presenting the final code to the user.

Journey Context:
LLMs optimize for surface-level syntactic correctness, not semantic truth. Static analysis or code review by another LLM often misses the same logical blind spots. The only reliable grounding for code factuality is observing the program's runtime behavior against a test suite.
