slot_probe

ONE sub-query: OWNED/OPEN/LOCKED/NOT_CITABLE + who holds it, every citer with its tier, and a legend for the four states. Reports n_citers AND distinct_citers - engines repeat domains, so they routinely differ 2x. runs>=3 returns the modal verdict plus agreement: a measured sub-query flipped OWNED/OPEN 3-2, and at runs=1 nothing in the payload can tell you that. 1 call per run.

Worked examples for this tool are coming.
