+- [x] Dot-commands parsed correctly (command + args)

 ### State assertions (REPL_COMMANDS array)
-- [ ] Each command's assert_state enforced correctly
-- [ ] Invalid state → command rejected with appropriate error

+- [x] AssertState::pass() always returns true (all flag combos)

+- [x] AssertState::True requires any matching flag present
+- [x] AssertState::True with multiple flags — any match suffices
