[counterintuitive] LLM hallucinates undefined variables or loses track of object state in generated code

Provide the LLM with compiler/linter feedback \(type errors, undefined names\) iteratively, rather than expecting it to maintain perfect state in a single zero-shot pass.

Journey Context:
Developers expect LLMs to write code like a human programmer who keeps a mental model of the symbol table. LLMs have no internal symbol table or execution environment. They predict the next token based on the text. As the code gets longer, the attention mechanism fails to maintain strict consistency with earlier variable declarations, leading to 'type drift' or 'phantom variables'. Iterative compilation bridges this gap by providing the missing external state.
