Zanzibar-style authorization graph engine (direct/chain/TTU/defeasible/ binary modes, condensed snapshots, value relations) with 39 rigor test campaigns. Includes fixes for snapshot binary writer/reader format mismatch (snapshot-of-snapshot corruption), possibility write-boundary validation, empty-graph snapshot serialization, relation lookup cache direction collision, config-redefinition cache invalidation, binary threshold semantics, defeasible compiled routing, and comparator reason whitelisting.
