 The numeric limits are validated at plugin construction: every cap except `maxRedirects` must be a positive finite number, and `maxRedirects` must be a non-negative integer. An invalid value throws rather than silently constructing a provider with nonsensical limits.

+## Model Experience
 
-SSRF / private-network protection (blocking private, loopback, link-local, multicast, and otherwise non-public destinations, with DNS-resolve-then-validate and per-hop re-validation) is **deferred** — see the [web capability seam RFC](../../../docs/rfc/implemented/architecture/2026-06-24-web-capability-seam.md). Until it lands, this provider is an SSRF primitive and **must not be enabled** in a deployment that can reach sensitive internal network targets.
+Indirectly, through [`dsh-tool-web`](../tool-web/README.md), which places this provider's `maxBodyChars`-bounded decoded text or markdown-shaped HTML under its fetch-result wrapper and retains provider failures while redirects, headers, and transport mechanics remain hidden.

+## Known Limitations and Deferred Work
+
+- **SSRF / private-network protection is deferred** — no blocking of private, loopback, link-local, multicast, or otherwise non-public destinations, no DNS-resolve-then-validate, no per-hop re-validation (see [the web capability seam RFC](../../../docs/rfc/implemented/architecture/2026-06-24-web-capability-seam.md)). Until it lands, this provider is an SSRF primitive and **must not be enabled** in a deployment that can reach sensitive internal network targets.
+- **Only textual content decodes** — html/xhtml and `text/*`-plus-JSON/XML families; a missing `Content-Type` or any binary type throws `WEB_UNSUPPORTED_CONTENT_TYPE`, and text-extractable PDF decoding is named deferred work.
+- **Charset comes only from the `Content-Type` header** (UTF-8 default) — an HTML `<meta charset>` declaration is ignored, and a declared-but-unrecognized charset label throws rather than falling back.
