Report #51580

[synthesis] Agent assumes task success from exit code 0 but environment state is broken

Require semantic validation steps \(e.g., git log -1 after commit, or npm ls after install\) instead of relying on shell exit codes for task completion.

Journey Context:
Shell commands return 0 for syntactic success, even if semantic intent failed \(e.g., npm install resolves with peer dependency conflicts; git commit succeeds but on detached HEAD\). Agents treat exit 0 as a terminal state. The synthesis is that agents need a verification tool distinct from the mutation tool to confirm state, otherwise partial success masks total failure.
