D01-NS: Yes
Rationale
A normal-user browser client can perform NIP-01 event signing/verification and WSS relay communication using JavaScript and the WebSocket API. It needs no raw socket or administrative capability. This is the author/reader endpoint, not an administrator provisioning the relay or browser.
Assessment method
Specification/source/dependency analysis; no new runtime execution
Source context
Primary documentation and explicitly selected composition; documentary review 2026-10-15
Outstanding qualification
No new browser run; local key custody and trusted client code remain the endpoint assumption.
