- command.c in full: the command dispatcher with repeat counts, run prefixes, ctrl-run door-stop mode, fight-to-death targeting, and all wizard debug commands; search, help, identify, d_level/u_level, call, current - main.c completed: Run()/playit() with the C double ROGUEOPTS parse; exit()-anywhere becomes a gameEnd panic recovered in Run - save.c + state.c: gob SaveState snapshot with explicit pointer-to- index fixups for equipment, monster rooms, and chase targets (the rs_fix_thing role); save file deleted on restore as in C; SIGHUP/ SIGTERM autosave hook - wizard.c completed (create_obj, show_map), passages.c add_pass - term/: tcell/v2 Terminal — the one third-party dependency — replacing curses and mdport's 900-line key decoder; shell escape via suspend - cmd/rogue: flags -s/-d, SEED (wizard), ROGUEOPTS, ROGUE_WIZARD Tests: full scripted sessions through Run (quit, descend stairs, 3200-move crash sweep, save-command round trip). Notable fixes found by tests: gob silently drops embedded fields of unexported types, and --More-- prompts swallow space-free input scripts.
