Changelog — Version History

24 Deep Dives covering ALL 25 systems. 327 claims with evidence mapping across E-E-A-T dimensions. Every system from NavBoost (S1) to Mustang/SuperRoot (S22) has analytical content with claim-level evidence codes. Build: 93 pages.

Three Deep Dives covering the content quality architecture: /deep-dive/original-content-score (13 claims, Experience primaer — measures content originality), /deep-dive/content-effort (11 claims, Expertise primaer — estimates editorial effort), /deep-dive/topic-embeddings (13 claims — focus vectors + radius for topic relevance). Together these complete the content quality picture: originality (what's new), effort (how much work), and relevance (what it's about).

Three Deep Dives: /deep-dive/is-calibration (14 claims, [A] hardest evidence — DOJ/sworn rater system), /deep-dive/spambrain (13 claims, [O] official + [B] leak — AI spam detection, scaled content abuse), /deep-dive/chard (17 claims, [B]+[O] — page-level content quality, YMYL standards, calibration chain IS->chard->NSR).

Two Deep Dives sharing the same patent (US7346839B2): /deep-dive/freshness-twiddler (17 claims: QDF, Instant Glue, content update scoring, staleness detection) and /deep-dive/date-triangulation (17 claims: six inception date sources, multi-source triangulation). Both have Stufe 2 patent bridges via Cutts/Haahr.

Fifth Schicht 2 article: /deep-dive/anchor-spam. 5 sections covering two-layer detection (phraseAnchorSpamPenalty + IsAnchorBayesSpam), Google bombing era, patent mechanism (US8577893B1 reference context analysis), ranking architecture, and SEO implications. 19 claims with evidence mapping.

Fourth Schicht 2 article: /deep-dive/hostage-sandbox. 5 sections covering passive damping mechanism, patent analysis (US7346839B2 Claims 38-40: domain expiration, DNS monitoring, name server quality), inception date formula (H = L / log(F+2)), ranking architecture, and SEO implications. 18 claims with evidence mapping.

Bidirectional cross-links: System pages now link to related Deep Dives and E-E-A-T Pillars. Deep Dive pages link to related Pillars. Chatbot corpus expanded with 65 Deep Dive claims (evidence-mapped) and 5 Pillar hub pages.

5 pillar hub pages: /pillar/eeat (overview), /pillar/experience, /pillar/expertise, /pillar/authority, /pillar/trust. Each connects primary and indirect systems to Deep Dives. Hub-and-spoke architecture complete.

Third Schicht 2 article: /deep-dive/q-star. 6 sections covering the DOJ-revealed two-signal architecture (Q* quality + P* popularity), NSR chunk-based computation, Q*/P* interaction, hand-crafted signal design (PXR0356), and SEO implications. 18 claims with evidence mapping.

Second Schicht 2 article: /deep-dive/panda. 8 sections covering Panda's site-wide demotion mechanism, the content farm era, the Navneet Panda name bridge (inventor name = update name = Stufe 1), patent analysis (6 Stufe 1 patents, 1 Stufe 2 Ofitserov dwell-time), BabyPandaV2 evolution, and SEO implications. 24 claims with evidence mapping.

First Schicht 2 article: /deep-dive/navboost. 7 sections covering NavBoost mechanism, click signals (goodClicks/badClicks/lastLongestClicks), 13-month window, DOJ trial revelations, patent analysis, ranking architecture, and SEO implications. 23 claims with evidence mapping.

Agent Rank patent family (US7565358B2, US8296293B2, US9002856B2, US20070033168A1) reviewed. All Google LLC, inventors Minogue/Tucker. No system mapping — entity level missing from 2024 API leak.

US8577893B1 'Ranking based on reference contexts' added as [P] to System 17 (Anchor-Spam / Penguin-Erbe). Inventors: Anna Patterson, Paul Haahr. Stufe 2.

US7953763B2, US8250114B2 (Google, Stufe 3): link farm detection via PageRank derivatives — link structure, not anchor text. US7533092B2 (Yahoo, not Google): TrustRank line. US7349901B2, US20090198673A1, US20110087648A1 (Microsoft, not Google).

US11354342B2 family (4 patents, Google LLC, inventors Carbune/Anders) reviewed and discarded. Stufe 3 — functional similarity only.

US7346839B2 added as [P] to System 19 (hostAge-Sandbox). Claims 38-40: domain legitimacy scoring (expiration date, DNS records, name server age). Stufe 2.

US7346839B2 added as [P] to System 24 (FreshnessTwiddler / RealTimeBoost). Claims 6-14, 15-21, 22-29: content update scoring, staleness detection, link freshness. Stufe 2.

US7346839B2 added as [P] to System 25 (Datums-Triangulation). Claims 2-5: multi-source inception date. Stufe 2.

7 patents added as [P] to System 16 (Panda): US8682892B1, US9195944B1, US9031929B1, US9760641B1, US9767157B2, US9684697B1, US10055467B1. 6x Stufe 1 (inventor Navneet Panda = update name), 1x Stufe 2 (Ofitserov, dwell-time).

3 patents added as [P] to System 1 (NavBoost): US10229166B1, US8661029B1, US8938463B1. All Stufe 1 — inventor Hyung-Jin Kim confirmed as NavBoost developer via DOJ Exhibit PXR0356.

US9092510B1 discarded (Stufe 3): different inventors (Stets, Paskin), no Kim connection. Temporal component could relate to FreshnessTwiddler but functional similarity only.
