What is ~alter?

Most people who read about ~Alter are here about their own identity, and you are not. You are building something that has to know who its users are, which makes you the party who asks, stores the answer, and carries it afterwards.

The asking is the cheap part. What comes after it is the encryption at rest, the retention schedule, the access review, the deletion request that arrives long after they stopped using you, and the notification you send if any of it ever leaks. You carry all of that for data whose only source was somebody typing into a box you built, unverified by anyone, and out of date from the day it was entered.

~Alter is a record kept under a name the person owns, and what is in it was read from what they have done rather than typed into a form. Your code reads that record at the point it needs an answer, and holds none of it once the call returns. The person decides in advance what your application is allowed to see, which puts the consent conversation on their surface rather than on yours.

Checking that somebody exists costs nothing and discloses nothing past the fact of them. A read that goes further is priced, and three quarters of what you pay for it reaches the person whose record was read. You are buying an answer for as long as you need it rather than taking custody of one.
