This is a structurally different surface from the\n`hub.docker.com/v2/repositories/.../tags` convenience API already in the corpus (that one is\nkeyless and rate-limited at ~180/IP on the Hub web API). The registry v2 pull path's limit is\n**100 pulls per 3600-second window**, keyed by `docker-ratelimit-source` (the caller's IP for\nan anonymous token) and reported in **both** the legacy `x-ratelimit-*` family and the IETF\ndraft `ratelimit-*` family simultaneously, each carrying the window as `;w=3600` rather than a\nseparate reset timestamp.
