Chorus

A text-only card-game prototype — Cultist Simulator / Book of Hours-shaped games expressed entirely as sentences, deterministic end to end.

Build:

cargo build --release     # the bins land in target/release/

Play (line REPL):

cargo run --bin chorus -- scripts/the-nightjar-flyer.txt   # or any script file

A real save, replayed by the analyzer — inside the REPL save <file> writes the action log, and reach --from-state reads it back as a midgame world:

printf 'look\nread the manifest\nsave /tmp/log.jsonl\nquit\n' | cargo run --bin chorus -- scripts/the-nightjar-flyer.txt
cargo run --bin reach -- scripts/the-nightjar-flyer.txt card THE_WAX_CYLINDER --from-state /tmp/log.jsonl

Analyze a script — reach answers "can the player obtain card X?" statically, over the compiled script, before play:

cargo run --bin reach -- scripts/the-nightjar-flyer.txt card THE_WAX_CYLINDER --why
cargo run --bin reach -- scripts/the-nightjar-flyer.txt all --cost --by 600
cargo run --bin reach -- scripts/the-nightjar-flyer.txt demand "aspect:secret>=2"
cargo run --bin reach -- scripts/the-nightjar-flyer.txt verb WORK
cargo run --bin reach -- scripts/the-nightjar-flyer.txt world
cargo run --bin reach -- scripts/the-nightjar-flyer.txt graph   # Graphviz DOT

card prints one card's verdict and proven paths, all walks every name, demand matches a slot query, verb reports one verb, world renders the whole-world dashboard, and graph emits the mint dependency graph as DOT. --json turns the card faces machine-readable; --help prints the full table.

Lint a script:

cargo run --bin lint-scripts                                  # the sorted scripts/ default
cargo run --bin lint-scripts -- --reach scripts/the-nightjar-flyer.txt   # + the reach design-smell findings

--color opts every bin's text faces into ANSI highlighting (default off — the plain output is plain bytes).
