Sunnydale Veterinary Group deploys its new agent to production, then immediately deletes the sandbox where it was built and tested to save storage. Three weeks later a topic misclassification is discovered in production. Why does this decision complicate fixing the problem?

The sandbox is the safe, isolated place where a fix can be built and validated with Testing Center before it ever reaches production again. Deleting it removes that safety net, so fixing the misclassification now either requires standing up a new sandbox and repopulating enough configuration to test properly, or editing directly in production without a validated staging step — a materially riskier path for a change touching real pet-owner conversations. Claiming fixes can always be made safely directly in production ignores the entire rationale for a sandbox-then-deploy lifecycle that this domain is built around. Testing Center is not production-only; it is commonly run against a sandbox specifically so validation happens before production is touched, which is the whole point of the environment. This is not scoped narrowly to Multi-Agent Interoperability — the value of a sandbox for safe iteration applies to any topic, action, or instruction change, including ordinary classification fixes like this one. The lesson: keeping a working lower environment available is part of sound lifecycle discipline, not an optional convenience.
