Description

We should use a reference count-like system to keep track of the EOS state. Anytime an operation does something that we believe breaks thermodynamic consistency, we increment the counter. If the counter > 0, then we know not to trust the state, and instead need to call clean_state.

This will let us be more consistent with the EOS calls.

Research direction

Start by tracing the existing EOS calls and the clean_state entry point to identify where thermodynamic consistency can be broken. Determine which operations must update the reference count and how state validity is checked. Done means the counter reliably triggers clean_state before untrusted EOS use, with coverage for the affected operations.
