A NIP-17 wrap is signed by a throwaway key with the sender sealed under two layers of nip44, so no server can filter DMs by who sent them. The notifier now ships the wrap inside the push payload and the service worker opens it locally: a message from someone you follow arrives with their name on it, a stranger's is dropped, and your own sent-copy — every DM is wrapped to the sender too — no longer notifies you about what you just typed. That needs the nostr identity key in the worker's IndexedDB, which dm-inbox.js states plainly: for a seed-derived identity it is a second copy of a key localStorage's seed already yields, and it exists only to keep strangers out. A remote signer never hands its key over, so those wallets store no secret and keep getting unfiltered notifications rather than silence. Silence is always the riskier failure here, so the rule leans the other way whenever it isn't sure: a wrap we can't open notifies, an account with no contact list published notifies (otherwise a new user's welcome message would vanish), and anyone you already have a thread with counts as known whether or not you follow them. The server-side DM cooldown drops to a second — with the device discarding pushes, a throttle there would let a discarded one swallow the message behind it.
