Mandate 3, on v1: a contract we replaced

Health Factor, job #3

Open on v1, where nothing will settle it again

Superseded by v2. Its mandates and settled epochs are still readable, and still counted in the book. New mandates open on the canonical market.

This record is kept readable because the hours it settled really happened, and a market that hides its earlier books when it redeploys is doing the thing we exist to catch.
