Rige is where a company keeps what it decided — on one shared record, with a date and a name on every entry.
Today that knowledge lives in each person's own drawer: a chat thread, a folder, a conversation two people remember differently. None of that can be cited, and none of it survives the person who holds it.
Anyone on the inside can draft. Signing is an act of whoever has the authority to sign — and nobody signs their own.
Writing something down is not the same as putting it on the record. On the record, a note takes the shape of what it actually is: something declared, something someone committed to, or something stated as true. Each one binds differently.
And nothing is quietly overwritten. When a rule changes, the old one is marked replaced and the new one takes force — so «is this still true?» has an answer you can read instead of a person you have to find.
Ask it anything and the answer comes with its source: what governs, who signed it, and when.
