Test, Build, and Deploy / test-build-deploy (push) Failing after 54s
New lib/datalog/strata.sx: dl-build-dep-graph (relation -> deps with :neg flag), Floyd-Warshall reachability, SCC-via-mutual-reach for non-stratifiability detection, iterative dl-compute-strata, and dl-group-rules-by-stratum. eval.sx refactor: - dl-saturate-rules! db rules — semi-naive worker over a rule subset - dl-saturate! db — stratified driver. Rejects non-stratifiable programs at saturation time, then iterates strata in order - dl-match-negation — succeeds iff inner positive match is empty Order-aware safety in dl-rule-check-safety (Phase 4) already required negation vars to be bound by a prior positive literal. Stratum dict keys are strings (SX dicts don't accept ints). Phase 6 magic sets deferred — opt-in path, semi-naive default suffices for current workloads.
