🙇 Japanese Keigo Relationship Risk Gate

Japanese Keigo Relationship Risk Gate turns owner-supplied normalized evidence into a deterministic local preflight. Japanese business wording can be grammatically plausible yet socially wrong for the sender, recipient, hierarchy, setting, or requested level of formality. Treats relationship context and approved patterns as evidence and always requires exact-message human review; it does not generate authoritative keigo. It makes no network request and performs no import, translation, rewrite, upload, merge, delivery, publication, purchase, message, or account change. Stable findings and SHA-256 receipts support review, while PASS remains explicitly narrower than source truth or authorization.
