cloudflare

Scope

Covers the Cloudflare developer platform as a control plane and a runtime: the Workers isolate model and its limits, wrangler configuration and CLI, bindings, Durable Objects (runtime semantics and class lifecycle), the storage products and how to choose between them on consistency and quota grounds, Workers static assets and the migration off Pages, Cloudflare's own observability surface, Workers testing, and Cloudflare One — Access, Gateway, the device client and Tunnel.

Verified against wrangler 4.131.0 with workerd 1.20260910.1. Rules that need a newer tool than the 4.x line carry a gate such as (Wrangler 4.107+). Limits and defaults were re-read from the official documentation rather than recalled; every claim is marked [verified] (reproduced locally, see ## Environment), [official] (documentation only) or [community].
