usage: okf check [-h] [--strict] [--ignore PATTERN] [--json] [--types TYPES] [target]
conformance scan: §9 hard rules + local invariants
target <bundle> or <bundle>/<subdir> (default: whole catalogue)
-h, --help show this help message and exit
--strict count warnings toward the exit code; each finding keeps its severity
--ignore PATTERN suppress rules: an exact rule ID, or a prefix ending in `*` (kc/*,
okf/link/*); repeatable, added to .okf.toml ignore_rules; suppressed findings
--json print one JSON envelope {command, ok, data, warnings, error}
--types TYPES explicit TYPES.md path (overrides .okf.toml types_source)
