[synthesis] Partial file edits creating entangled state dependencies across agent steps

Implement atomic edit verification: after every file modification, verify that the resulting AST \(Abstract Syntax Tree\) or file state satisfies the preconditions for the next planned step before proceeding; if partial \(e.g., import added but target missing\), rollback immediately rather than proceeding to dependent steps.

Journey Context:
Standard advice is to verify edits with tests, but tests are expensive and slow. The synthesis reveals that the danger isn't just 'wrong edit'—it's 'partial edit that looks right to subsequent steps'. Alternatives like immutable state \(copy-on-write\) help but don't prevent the logical confirmation bias. The AST verification fix specifically targets the entanglement by checking structural prerequisites before allowing state to propagate, breaking the chain at the moment of partial failure rather than letting it cascade through subsequent steps that confirm the partial state as complete.
