Irreversibility
An essential property distinguishing physical interaction from software operation: once a physical action is executed, its consequences cannot be removed by rolling back state, requiring the agent to establish safety boundaries and risk assessment mechanisms before execution.
Timeline (last 90 days)
The paper identifies five physical constraints, including partial observability, irreversibility, and unverifiable outcomes, which together lead to fewer pre-fixed choices and less room for error correction.
Software systems naturally support undo stacks, snapshot rollback, and idempotent retries, allowing agents to trial and error at low cost; once a physical action is executed, its consequences cannot be eliminated through state rollback.
The two-dimensional grading of 'irreversibility × data exposure surface' proposed in the article is essentially a risk matrix method, similar to failure mode and effects analysis (FMEA) in the aviation and medical fields.
