Platform Changelog & Releases

P0 Content Accuracy & First-Party Google Standards

• Request Indexing Quota Clarification: Removed unsupported claims of a fixed "10–50 URLs/day" quota in Module 1 Lesson 3. Documented official Google rate-limit behavior and established clear boundaries between GSC Request Indexing and the restricted-access Google Indexing API (restricted exclusively to JobPosting and BroadcastEvent).
• 100% Indexing Claim Removal: Eliminated all claims suggesting technical architecture can guarantee 100% indexing in Module 7 Lesson 4. Replaced with the realistic engineering mandate: making content discoverable, crawlable, renderable, and eligible for indexing while respecting Googlebot crawl demand and quality evaluations.
• Sitemap Signal Demotions: Clarified in Module 4 Lesson 1 and Module 7 Lesson 4 that Googlebot completely ignores <priority> and <changefreq> tags. Dynamic sitemap generation upgraded to focus strictly on accurate <loc> and authentic content <lastmod> timestamps.
• Telemetry Boundary Clarification: Clarified in Module 0 Lesson 0 that GSC provides Google search ecosystem telemetry and does not replace server access logs, real user monitoring (RUM), GA4 product analytics, or non-Google webmaster portals.
• Search Analytics Nuances: Clarified in Module 3 Lesson 1 the difference between aggregate query totals and anonymized/long-tail query omission, and refined Average Position definitions across device/geographic segmentation.

Freshness Metadata & Official Source Integration

• Zod Content Schema Expansion: Upgraded Astro content collection schema to require publishedAt, updatedAt, reviewedAt, author, topics, and structured sources.
• First-Party Source Cards: Enriched all 27 lessons with dedicated "Official Google Documentation & Primary Sources" link cards pointing to Google Search Central, Search Console Help, and Google Developers.
• Dynamic XML Sitemap: Upgraded /sitemap.xml to dynamically derive <lastmod> from actual lesson content modification dates rather than build timestamps.

Editorial Trust Layer & Methodology

• Launched dedicated transparency pages: About the Platform, Author Attribution, Technical Methodology & Source Hierarchy, and this Changelog ledger.
• Added rich Schema.org TechArticle, ProfilePage, and semantic breadcrumb navigation across the platform.
