`--no-cache-filter=lint` is silently ignored by BuildKit when no stage matches the name, so the entire anti-false-green mechanism hung on one unvalidated magic string: renaming or mistyping the `lint` stage would have left the lint layer served from cache and `script/lint` reporting green having linted nothing. Reproduced here — with the filter pointed at a nonexistent stage and no `--target`, an unchanged tree built with `RUN golangci-lint run ... CACHED` and exited 0. `--target lint` closes it: a stage name that does not exist now fails loudly (`target stage "nosuchstage" could not be found`, exit 1) instead of passing. The two flags name the same stage from the same string and validate each other; both the script and the stage definition in Dockerfile.lint carry a comment saying they must be kept in sync. `--output=type=cacheonly` drops the image export. Nothing consumes the image — the deliverable of this build is an exit code — and the export cost seconds per run and left one dangling image behind every time, on a host where pruning is prohibited. The lint stage still executes and a lint failure still exits non-zero, both verified rather than assumed. TODO.md: the 2026-08-07 entry's claim that the repo has no linter pin and lints on the host is marked superseded in place rather than rewritten; the narrowed scaffold exemption now names `.dockerignore` alongside `Dockerfile.lint` and `script/lint`; and the specific wall-clock timings are replaced by the durable property they were evidence for, since they vary per host and per run.
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

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: make test 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 (script/lint, which runs golangci-lint inside the
pinned container built from Dockerfile.lint — it is never installed on the
host, so docker is required), make test (the suite, under the race detector
with coverage and a timeout), and make check (all three). Use the targets
rather than invoking go test directly — they carry the flags the project
relies on.
