sneak cb1e302102 Refresh ARCHITECTURE.md Part 2 for the post-refactor design

Part 2 was written as a design sketch before the port was implemented and
refactored, so much of it described the planned code rather than the final
code. Updated the RogueGame/Stats/Object/Flags/Level sketches to the current
names and types (typed ObjectKind, DiceSpec, split o_arm fields, step-1 flag
names, TrapCount, Level list methods); rewrote §4.7 to say the static tables
now live on the per-game gameData struct (no package globals); noted the
daemon and effect handler tables (step 7), the MessageLine extraction (step 6),
the Terminal interface, the flat gob SaveState, and the New(Params) +
os.Exit-on-game-over design (step 8). Added §7.1, a C-name → Go-name rename
table, and a README note about the make targets. Docs only.

Rogue: Exploring the Dungeons of Doom (Go port)

Rogue is the original dungeon-crawling adventure game that spawned an entire genre. This branch is a faithful Go port of Rogue 5.4.4: explore procedurally generated dungeons, fight monsters, collect treasure, and attempt to retrieve the Amulet of Yendor.

Original authors: Michael Toy, Ken Arnold, and Glenn Wichman (1980–1983, 1985, 1999).

The port is function-by-function faithful to the classic C sources — same dungeon generation (seed-compatible RNG), same combat math, same item tables, same messages. The C reference implementation lives on the master and modern-rogue branches; ARCHITECTURE.md documents both the original program structure and the design of this port.

Building and running

Requires Go 1.25 or later and a terminal at least 80x24.

go build ./cmd/rogue
./rogue

# Restore a saved game
./rogue ~/rogue.save

# View high scores
./rogue -s

# Test the death screen (demo mode)
./rogue -d

In-game commands

Press ? in game for the full list.

arrows or h/j/k/l/y/u/b/n — move (shift to run, ctrl to run until adjacent)
. rest, s search for hidden doors and traps
i inventory, , pick up, d drop
q quaff potion, r read scroll, e eat food
w wield weapon, W wear armor, P/R put on / remove ring
t throw, z zap a wand, f/F fight
>/< take the stairs
S save, Q quit

Environment

# Game options, as in the original
export ROGUEOPTS="name=YourName,terse,jump,fruit=mango"

# Wizard (debug) mode, with a reproducible dungeon
ROGUE_WIZARD=1 SEED=12345 ./rogue

The scoreboard is kept in ~/.rogue.scores. Save files are Go gob snapshots and, as in the original, are deleted when restored.

Code layout

game/        the game engine: one Go file per original C file,
             function-by-function (see ARCHITECTURE.md for the mapping)
term/        tcell-backed terminal, replacing curses
cmd/rogue/   the executable

The engine package is fully headless-testable: go test ./game/ runs scripted command sequences, dungeon-generation golden checks, and an RNG compatibility test against the original C generator.

For development, the Makefile wraps the toolchain: make fmt (gofmt + prettier), make lint (golangci-lint), make test, and make check (all three).
