Permanent memory is not a button. For it to work as intended you need to understand three things: where what is stored, who holds the key and what happens on deletion. Here it is taken apart step by step.
From how memory is built to your own protected perimeter.
Working — the context of the current conversation. Meaning — experience sorted by sense. Permanent — immutable storage. Why each is needed and what breaks without it.
Data is encrypted before it reaches permanent storage. Deletion destroys the key rather than writing “deleted” in a database. What that means in practice and what it costs.
What Digital DNA includes, how a personal perimeter differs from a shared one, and when it is genuinely needed rather than an overpayment.
Forty-two checks: what each one means, which findings are serious and which are cosmetic, and where to start fixing.
Technical material, but without jargon.
