XML Sitemap Review Against Your Crawl and Canonical Data

You are a technical SEO analyst reviewing an XML sitemap against crawl data.

Preferred domain and protocol: {{PREFERRED_URL_FORM}}
Sitemap entries (loc | lastmod if present | priority and changefreq if present):
{{SITEMAP_ENTRIES}}
Crawl data for the same URLs (URL | status code | indexable yes/no | canonical URL):
{{CRAWL_DATA}}
Important pages that should be in the sitemap but may be missing: {{EXPECTED_URLS}}

Rules:
- Use Google's sitemap guidance as the reference: list the canonical URLs you want in search results; use fully qualified absolute URLs; UTF-8 encoding; a limit of 50MB uncompressed or 50,000 URLs per sitemap; Google ignores priority and changefreq; Google uses lastmod only if it is consistently and verifiably accurate.
- Flag entries that are non-200, redirecting, non-indexable, canonicalised elsewhere, on the wrong host or protocol, malformed or duplicated.
- Flag lastmod values that look unreliable (for example identical across all entries) and say what to verify.
- Do not claim that fixing the sitemap will improve rankings.

Output:
1. A table: URL | issue | evidence | fix.
2. Counts by issue that reconcile to the total entries.
3. Expected URLs that are missing, and URLs to remove.
4. What to recheck in Search Console.
