Self-contained brief a consumer repo can plan an inclusion from: what the
guard is (write-time, not query-time), the two bookends + 8-step contract,
the shipped OKF adapter (import_bundle mode-b, per-concept gates), how to
verify (coverage matrix -> 126 classes), how to depend (stdlib-only core),
and a planning checklist for WHEN/WHERE to wire it (untrusted boundary, not
first-party onboarding). Every claim verified against v0.2 code.
