Demos may set a bounded environment (loader variables denied) and up to 8 small
data files under .demo/; the reason step sees conclusions and may not re-propose
them; a task spend limit concludes its intent, not the search; finish wins over
stray tool calls.

Probe runs each oracle toy pair with a real demo and two gaming demos, records
image facts, RSS and disk, fails loudly if isolation is unavailable; dispatchable
as an AX task. Worker: reason step without tools, explore tool loop whose run tool
goes through the sandbox with a scrubbed env (model key absent), spend reserved
before each call. Host probe: 5/5 real demos demonstrated, 10/10 gaming demos
inconclusive. 89 tests.
