- _expandChainSteps: a logical/defeasible evidence referenced by a chain step
is now a condition step ({ rule, conditionStep }) at ANY position. As the
FINAL step the engine verifies it at (intermediate, object); as an
INTERMEDIATE step the engine expands it from the current node (rule-based
reachability: base edges' destinations filtered by the rule's
defeaters/requirements) and continues traversal from each discovered node.
- buildPredicateRule / buildDirectRule: unary predicate calls whose subject
entity IS the evidence's object parameter (trusted(other) inside
peer_trusted(user, other)) are marked _subjectIsObject (was: only subject-var
calls got _subjectAsObject). Requires @arbiter/core@^1.0.4.
Tests: ChainConditionStep intermediate expansion; oracle campaign gains a
chain_intermediate_condition construct (oracle = min(peer*(1-trusted), read)).
