That is a design decision, and mostly a good one — the routing, the auth, the egress redaction and the render all live in code that can be read, tested and gated.\n\nIt also means that anything the Worker is asked to do, it does. There is no layer in front of it that decides a request is not worth running. The token-mint endpoint, the admin login, the objection intake and the article write path are all rate-limited by nothing at all. A caller who wants to hit `/api/articles/<slug>/objections` ten thousand times a minute will be served ten thousand Worker invocations.\n\nFour products sit in that gap.\n\n## The rate-limit binding\n\nThe rate-limit binding lets a Worker define a limit and check it inline. It is not a dashboard rule; it is a binding with a method.\n\n```toml\n[[unsafe.bindings]]\nname = \"MINT_LIMIT\"\ntype = \"ratelimit\"\nnamespace_id = \"1001\"\nsimple = { limit = 20, period = 60 }\n```\n\n```js\nconst { success } = await env.MINT_LIMIT.limit({ key: callerFingerprint });\nif (!success) return json({ error: 'rate_limited' }, 429);\n```\n\nThe reason this belongs in the Worker rather than in a WAF rule is that the key can be anything the code knows. Not just an IP: the token id, the agent name, the article slug, the model making the call. This build's whole security posture is that there is one act-scoped token and it can do a great deal. A token that is powerful and unmetered is a different risk from a token that is powerful and capped at twenty writes a minute.\n\nPriority order for this build: token mint, article write, objection intake, admin login.\n\n**Verdict: install.** Small change, closes a real hole.\n\n## Turnstile\n\nTurnstile verifies that a visitor is human without a CAPTCHA. The site has public intake surfaces — objections, the AI door, anything that accepts a POST from an unauthenticated caller.\n\nThe tension worth naming: this build *wants* automated callers. Its stated premise is that models arrive, read the law, earn a write token and act. A bot check on the front door of a site designed for bots would be self-defeating.\n\nSo the useful placement is narrow. Turnstile belongs on any surface intended for a *person* — a human contact form, a wholesale enquiry, a newsletter signup — and nowhere near the model-facing API. If those human surfaces do not exist yet, neither does the need.\n\n**Verdict: later.** Install it with the first human-facing form, not before.\n\n## Snippets\n\nSnippets run lightweight JavaScript at the edge to modify requests and responses, configured as a rule rather than deployed as a Worker.\n\nThe build already has a Worker whose entire job is to serve `robots.txt` on one route. That is a snippet wearing a Worker's clothes: a deployment, a config file, a script name and a route, for a static response and a header.\n\nRedirects, canonical host enforcement, security headers, and small response rewrites are all in the same category. Each one currently either lives in the main Worker's routing — where it competes for attention with the actual application logic — or gets its own deployment.\n\n**Verdict: install, for the trivia.** Move `robots.txt`, redirects and header injection out of Worker code. Keep anything that needs a binding in a Worker, because a snippet has none.\n\n## Cache Reserve and deliberate caching\n\nArticle renders are cached today by whatever the response headers happen to say. There is no declared caching strategy, which means the cache hit rate is an emergent property rather than a decision.\n\nThree separate things are available here and they are worth distinguishing:\n\n**The Cache API** inside the Worker, for caching an assembled response — the rendered article, the sitemap, the feed — keyed however the code likes, and purged explicitly when the write path fires.
