Description
Crater's NotePolicy checks only a blanket Bouncer ability (manage-all-notes / view-all-notes) with no company-ownership comparison, unlike InvoicePolicy and other sibling policies which additionally verify ->hasCompany(->company_id). Any authenticated user of one company can read, edit, or delete another company's notes by ID.
