Module exit_code 

What a command’s exit status means.

exit_code 0 "all checks passed"
exit_code 1 "a check failed"
exit_code 2 "configuration error"

Declared at the root for the CLI-wide convention and on a command for what it adds or refines. A man page conventionally carries an EXIT STATUS section and this project’s renderer had no way to fill one; an agent reading the spec through usage mcp had no way to tell “one check failed” from “the tool broke”.

Folding is per code and nearest-wins, so exit_code 1 "a check failed" on a command refines a CLI-wide exit_code 1 "error" rather than replacing the whole table. The alternative — a command that redeclares anything owns the full set — would make every command restate 0 and 130.
