[synthesis] Agent code passes local execution but fails in CI due to implicit environment dependencies

Hash the agent's sandbox environment \(OS, packages, env vars\) and compare it against the CI target environment hash. Fail the agent's execution phase early if the hashes diverge, rather than letting it iterate on code that will never work in the target.

Journey Context:
Agents run in isolated sandboxes. They write code, run it, see it works, and submit. But the sandbox has a different Node version, a missing OS library, or different locale settings than the target CI. The agent's code is technically valid but environmentally incompatible. The agent wastes turns 'fixing' code that isn't the problem, eventually producing a fragile hack that passes locally but fails CI. The synthesis of sandbox architecture and agent self-correction loops reveals that environment parity is a prerequisite for agent self-correction; without it, the loop is just a hallucination generator.
