+## Original Advanced Stronghold composition — 5 October 2026
+
+The original fresh Discovery entry admits unused original Stronghold Cards in
+Advanced2–6 with classic, supported selected E1/E2 or standalone Ecaz OR
+Moritani rosters. The separate fresh classic `leader-skills --discoveries`
+entry likewise preserves all14/base33/Discovery7/8/Strongholds6. Either may
+retain original Tech at3–6. Basic Strongholds, native Discovery skill families,
+Nexus/HW/independent variants/other previews and save conversion stay separate.
+The existing Nexus/Discovery composition above is unchanged.
+
+No new Stronghold Card is created for Jacurutu. Original actual end-Mentat
+custody supplies held benefits in their named territory or a declared HMS
+copy, never an inherited defense or subsidy inside a different nested site.
+Original free entry and ordinary nested invoices retain physical/trained
+groups; named support reductions change actual debit, not pledged rescue
+eligibility. Typed losses, winner cleanup and Tech/Face Dance retain their
+existing order. Contested Discovery and other pending sources are not decided.
+
+The actual CLI entries remain `--profile discovery` or
+`--profile leader-skills --discoveries` with selected original Advanced
+Strongholds in the fresh lobby. The genuine runner additionally offers
+`discovery-stronghold`, `discovery-stronghold-tech`,
+`discovery-skills-stronghold`, `discovery-skills-stronghold-tech`;
+new4000–4300 ordinal bands preserve earlier defaults and scenario seeds.
