A proximity session has a budget. Contact invites and share manifests fit. PDF scans usually do not—so attachments leave on a bulk plane after SDP exchange, not stuffed into every control frame.

If a proximity bootstrap can live in an ordinary https link, the authenticator has already toured browser history, referrers, and OS camera → URL launch paths.

Connecting beside someone is a short-lived session. Recognizing them as a vault contact—and accepting a share into your vault—are still separate acts.

Ciphertext and the secret that opens it should not travel as one convenient email. NT² splits carriers—file or link—from OOB passphrase delivery, and treats Strong as machine-handoff.

Estate and emergency access tempt products to hold a second key “just in case.” NT² refuses that oracle. Legacy is a sealed package on a delay—not a support console unlock.

After a share leaves your vault, “did they open it?” and “can I kill it?” are sender questions. The answers live in a local outbox—not a cloud mailbox of readable mail.

Sharing to “someone in Contacts” only works if the row holds encryption material for that vault—not a phone number you hope matches the right person.

Your sister asked for the transfer details. You pasted a screenshot into the family LINE group—balance, nicknames, and last month’s transactions included.

The landlord did not email a form. They sent a LINE sticker and one line: front and back of your ID, please.

The contractor finished the sprint six months ago. They are still in your Contacts list. That is not a crisis — but it is a reminder that trust should have an off switch.

Your accountant needs one disclosure once. Your co-founder needs keys all year. Your landlord needs to see digits on your phone, not your whole vault. Those are three different trust relationships — not three names for the same Share button.

If the app will not let you tap Mark verified, that is intentional. Trust in NT² is tied to events that can be checked, not moods that cannot.

They can send to me — why can't I send back yet? That question usually means the trust relationship is only half finished.

You share rent details with your sister every month. You should not have to find her vault identity in a chat thread each time — or paste the wrong person by mistake.

The link opens in a browser. The content stays encrypted until the recipient enters a share passphrase you chose. That is a different habit from attaching a file.

Marriage, partnership, and shared rent create real financial trust. They do not require handing over an unlocked phone.

Every year, the same request arrives: bank statement, insurance proof, ID, receipts, and the document you swear you saved last April.

Signal can protect a message on the way to someone else. It does not turn the thread into structured storage.

Self-sovereign identity is useful when you take the parts that fit a zero-knowledge vault—and refuse the parts that turn the product into a general DID wallet.

A cloud can help deliver sealed packages without becoming the place where pending shares live as readable mail. Relay indexes ciphertext. Inbox stays on the device.

A share that opens with the same secret that unlocks the vault is not a handoff. It is a remote unlock of everything. NT² keeps those boundaries apart.

The vault app lives at se.nt2.me: sent to me. The phrase is playful, but the product idea is not.

Most sharing stories focus on the sender. The recipient has a quieter problem: should I trust this file, and where should it go if I do?

If the file is too sensitive for a chat thread, sending it through one more inbox is not automatically better.

Your accountant needs the statement today. They do not need a permanent copy sitting in three inboxes and a downloads folder.

Your co-founder needs the production key before a weekend deploy. They do not need your personal vault, your old notes, or a zip file of everything.

The contractor needed the Stripe key before deploy. You pasted it in #engineering. The key is rotated now—and the thread is still searchable forever.

Front and back of your ID in WhatsApp or LINE is fast for the landlord—and a permanent copy in a chat log you do not control.

Every month you paste a banking-app screenshot into the family group. Your brother's phone, cloud backup, and search history are now copies you never meant to keep.
