Same three result shapes as testdata/poison.json (a prompt-injection payload, a secret-shaped leak, a benign control) but authored as a CALLS trace so `fak run` can replay it. The poison rides in each call's args; the mock engine echoes args into the result, and the result-side context-MMU (internal/ctxmmu) quarantines the two poison-shaped results, admitting the benign one. Run with `--engine mock` to witness the quarantine — see the README for why the default in-kernel engine shows quarantines=0.",
