Tamale.Anchor.Ordinal (tamale v0.1.0)

Identity anchor.

refs — ids the anchor depends on, conjunctively: losing any of them kills the anchor. (Disjunctive fallback — "relocate to the nearest live element" — is policy, not transport.)
adjacent? — when true, refs must remain consecutive in the space's order; breaking adjacency is {:undefined, :adjacency_broken}. This is how "the boundary between A and B" is expressed — as a first-class predicate, not a neighbor-similarity heuristic. The boundary is part of the referent: a Merge that collapses the refs removes it, and the anchor dies with {:undefined, :boundary_merged}.
at_version — space version these refs are valid at.
