 # Completed Steps
 
+- 2026-07-23 Refactor step 8 (refactor/constructor-style): constructor and exit
+  pass. NewGame(Config) → New(Params) and Restore takes Params, so the package's
+  primary type gets the canonical New() constructor with a named-field Params
+  struct (styleguide 139/159). The gameEnd panic unwind is gone: one game run is
+  one process, so myExit restores the terminal (new Terminal.Fini) and calls
+  os.Exit(0), and Run() no longer returns; the four Run()-to-completion tests
+  were reworked/dropped since death (combat or starvation) now exits the process
+  (TestScoreRendersList and TestRunDownStairs preserve what is still drivable;
+  save/restore stays covered by TestSaveRestoreRoundTrip). The 77-column wrap
+  sweep was dropped per sneak (2026-07-23): line lengths left as-is (lll caps at
+  88 and passes).
