A feedback request can arm a one-shot HTTPS callbackUrl. The submit that claims it (in the same transaction) POSTs the site, timestamps, and note count, never note text, with one retry, then clears it. The URL is never returned or logged, and a password change disarms it. CLI: site feedback --request --callback URL. MCP: callbackUrl on nzip_request_feedback. The nzip skill documents a T3 webhook recipe.
