Report #46225

[synthesis] Agent makes a minor incorrect assumption early and cascades into irrecoverable environment corruption by trying to adapt the world to its assumption

Implement state checkpointing and rollback at the tool-call level. If an agent executes a sequence of 3\+ file modifications that do not move the task closer to completion \(evaluated via a verifier\), force a git checkout to revert the environment and inject a context message explicitly stating the previous assumption was wrong.

Journey Context:
Agents lack the human intuition of 'undo.' If an agent assumes a file is in /src/app but it is in /lib/app, it reads the wrong dir, gets a file-not-found, and often decides to create the missing files to satisfy its logic, compounding the error. It treats filesystem mutations as irreversible sunk costs. The more files it creates to support a bad assumption, the harder it is to recover. Allowing the agent to mutate state without rollback mechanisms turns a simple hallucination into catastrophic environment failure.
