Remediation

• CORE-ACCESS-001 — Collapse the redirect chain to at most one hop.
• CORE-ACCESS-002 — Scope Disallow rules to specific paths instead of blocking `/` for `*`.
• CORE-ACCESS-003 — Allow search/retrieval crawlers (OAI-SearchBot, Claude-SearchBot, PerplexityBot, …) in robots.txt while keeping any training restrictions separate.
• CORE-ACCESS-004 — Restrict only the training-purpose crawler tokens; leave search/retrieval crawlers allowed.
• CORE-ACCESS-005 — Publish /sitemap.xml and declare it in robots.txt.
• CORE-ACCESS-007 — Point the canonical tag at a URL on this site's own host.
• CORE-ACCESS-008 — Remove the noindex directive from the meta robots tag or X-Robots-Tag header.
• CORE-ACCESS-009 — Remove or fix the broken references in llms.txt.
• CORE-ACCESS-010 — Fix the Content-Signal directive, e.g. "Content-Signal: search=yes, ai-input=yes, ai-train=no".
• CORE-MACHINE-001 — Fix the malformed JSON-LD blocks so every one parses (validate with a JSON linter before publishing).
• CORE-MACHINE-002 — Add JSON-LD with "@type": "Organization" declaring at least name and url.
• CORE-MACHINE-003 — Add JSON-LD with "@type": "WebSite" or "WebPage".
• CORE-MACHINE-004 — Add a stable identifier (sku, gtin, mpn, or brand) to the Product entity.
• CORE-MACHINE-005 — Add an Offer with price, priceCurrency, and availability to the Product entity.
• CORE-MACHINE-006 — Add a stable identifier (sku, gtin, mpn, or brand) to the Product entity.
• CORE-MACHINE-008 — Add the missing metadata tags and give title and description distinct content.
• CORE-MACHINE-009 — Use exactly one H1 per page and avoid skipping heading levels (e.g. h1 to h3).
• CORE-MACHINE-010 — Add a valid `lang` attribute to the `<html>` tag (e.g. `lang="en"`).
• CORE-MACHINE-011 — Add an alt attribute (or an explicit empty alt for decorative images) to every image.
• CORE-OPERABILITY-001 — Server-render (or statically pre-render) the core content so an agent's plain HTTP fetch sees it.
• CORE-OPERABILITY-002 — Collapse the redirect chain to at most one hop.
• CORE-OPERABILITY-003 — Add an ETag or Last-Modified header so agents can issue conditional GETs.
• CORE-OPERABILITY-004 — Fix or remove the broken references (sitemap, llms.txt, OpenAPI spec, policy links) so agents don't hit dead links.
• CORE-OPERABILITY-006 — Add a <label> (or aria-label/aria-labelledby) to every input/select, and a name or accessible text to every button.
• CORE-TRUST-001 — Add a clearly labeled contact or support link (a page or a mailto link) to the entry page.
• CORE-TRUST-002 — Publish a shipping policy page (cost, timing, carriers) and link it from the entry page's nav or footer.
• CORE-TRUST-003 — Publish a returns/refund policy page and link it from the entry page's nav or footer.
• CORE-TRUST-004 — Publish a privacy policy page and link it from the entry page's nav or footer.
• CORE-TRUST-005 — Publish a terms/conditions page and link it from the entry page's nav or footer.
• CORE-TRUST-006 — Add a Contact field (RFC 9116) to security.txt.

Limitations

• Scovant Core evaluates declared and static evidence only; it does not observe real agent traffic.
• Only reachability and syntax are checked; per-agent policy is evaluated by the other CORE-ACCESS checks.
• Only the declared robots.txt policy is evaluated; whether the crawler is actually served is not observed.
• Only the declared robots.txt policy is evaluated.
• Only the first-declared sitemap (or its first child, for a sitemap index) is fetched and validated.
• Only ISO 8601 date-formatted lastmod values are parsed; malformed dates are ignored, not penalised.
• Only the entry page's declared canonical is evaluated.
• Only the entry page's own robots meta tag and X-Robots-Tag header are checked.
• Absence is not penalised; the convention is emerging. Reference checks are HTTP status only.
• Absence is not penalised; the convention is emerging.
• Only `/.well-known/mcp.json` and the two candidate server-card paths are probed; a custom discovery location is not found.
• Only the `mcpServers` object at /.well-known/mcp.json is parsed; a server card is not covered by this check.
• This is a static text scan of already-fetched HTML for a marker string; the browser-side registration was not executed, so a marker's presence does not confirm the tools actually register or work.
• Only a fixed set of conventional paths, plus same-origin entry-page links naming openapi/swagger, are probed.
• Only the conventional /.well-known/oauth-authorization-server path is probed.
• Only the conventional /.well-known/oauth-protected-resource path is probed.
• Only well-formed-JSON parseability is checked; schema.org vocabulary correctness is not validated.
• Only the schema_org nodes on the sampled pages are checked; an Organization declared elsewhere on the site is not evaluated.
• Only the schema_org nodes on the sampled pages are checked.
• Only the sampled pages are checked; a product catalog not represented in the sample is not evaluated.
• Only the first sampled page that exposes a Product entity is checked.
• Only the non-entry pages in the sampled set are checked.
• Only the entry page's metadata is checked.
• Only the entry page's heading outline is checked.
• Only the entry page's `<html lang>` attribute is checked.
• Only the images on the sampled pages are counted.
• Static-HTML signal only: the raw fetched response is inspected, never rendered in a browser, so a site that hydrates real content very quickly may still be flagged here.
• Only the entry URL's own redirect chain is inspected; redirects encountered while fetching other sampled pages are not counted here.
• Only the entry response's own headers are checked; per-page-type validator strategy is not inspected.
• Only the capped set of references collected by the machine_links gatherer are checked; endpoints not linked from any declared document are not found. A declared MCP endpoint is recorded but never judged — Core does not perform the MCP handshake.
• `estimated_tokens` is a character-count estimate (chars / token_chars_ratio), never a real tokenizer count, and only the entry page is measured.
• Only forms on the sampled page set are inspected; a form behind client-side rendering that never appears in the static HTML is not seen.
• One extra request to a path that cannot exist (the URL is in evidence); a site that deliberately serves a 200 landing page for every path fails this check by design.
• Core never induces throttling; only 429 responses that happened to occur during the scan are examined, so most scans report N/A.
• Only the entry response and the sampled pages are inspected; a challenge served with an honest 403/429/503 is not a defect here (the access checks cover blocking).
• Only the entry page's anchors are scanned; a contact method reachable only from a deeper page is not found.
• Only a same-origin link discovered from the entry page's nav/footer/anchors is followed; a shipping policy reachable only from a deeper page is not found.
• Only a same-origin link discovered from the entry page's nav/footer/anchors is followed; a returns policy reachable only from a deeper page is not found.
• Only a same-origin link discovered from the entry page's nav/footer/anchors is followed; a privacy policy reachable only from a deeper page is not found.
• Only a same-origin link discovered from the entry page's nav/footer/anchors is followed; terms reachable only from a deeper page are not found.
• Only the conventional /.well-known/security.txt and legacy /security.txt paths are probed.
• Pricing-page discovery follows only a same-origin link from the entry page; the structured-price fallback checks only the sampled pages.

Core vs Cloud

Scovant Core measures passive, machine-facing signals. Scovant Cloud verifies how real agents actually behave, across providers, browser runtimes, security layers and time.

Methodology

Category weights are 25/25/20/15/15. Each check contributes PASS = 1, WARN = 0.5, FAIL = 0 to its category; ERROR lowers coverage (a document that could not be read counts against evidence), and N/A is excluded entirely. A scan scores INSUFFICIENT_EVIDENCE below a 60% coverage floor of its applicable weight. A full-selection scan that clears that floor but falls short of 85% coverage, or that hit any ERROR, is reported as DEGRADED (a score, no letter grade) rather than being silently graded on incomplete evidence. Running with checks narrowed or widened via --include/--exclude/--experimental instead reports a NOT_CANONICAL Subset Diagnostic Score over that subset, not the full Core Score.
