Capture the current state: 17 library files (1229 LOC), 61 test files (4360 LOC), 551/551 tests passing. Phases 1-5 fully done; Phase 6 covered by minimal FD (ino, all-distincto) plus an intarith escape hatch; Phase 7 documented via the cyclic-graph divergence test as motivation for future tabling work. The lib-guest validation experiment is conclusive: lib/minikanren/ unify.sx adds ~50 lines of local logic over lib/guest/match.sx's ~100-line kit. The kit earns its keep at roughly 3x by line count. Classic miniKanren tests green: appendo forwards/backwards, Peano arithmetic enumeration (pluso, *o, lto), 4-queens (both solutions), Pythagorean triples, family-relation inference, symbolic differentiation, pet/colour permutation puzzle, Latin square 2x2, binary tree walker.
