Source: Derived 2026-10-29 from zbll-t, zbll-u, zbll-l, zbll-h, zbll-pi, zbll-s, zbll-as, pll: the cases the engine finds match the rule "edges-phased", with their sources' definitions and algorithms, each algorithm re-checked against this set's goal. Every algorithm shown was checked by the logic engine; rejected ones are listed in docs/db-exclusions.md.
