[synthesis] Agent reuses a variable name from a previous sub-task, causing infrastructure scaling operations to multiply by the wrong factor

Enforce strict variable scoping in agent memory by prefixing all variables with their task/namespace ID, and implement static analysis checks on generated Infrastructure as Code before execution.

Journey Context:
An agent defines 'count = 5' for a batch processing task. Later, in an infrastructure scaling task, it uses 'count' assuming it's the cluster node count \(e.g., 3\), but gets 5. It scales to 5x the intended capacity. The synthesis is that LLM context windows lack lexical scoping; variables from one 'turn' or 'tool call' bleed into the next. In IaC, this context leak translates directly to financial or operational catastrophe because the agent executes state changes with phantom values.
