Sphinx Erosion Three-Position Layer-4 Cluster
concept
Instead of picking a winner, the engine deliberately holds three different scientific dates for the Sphinx at the same time.
Who they are
An engine-created grouping (added April 2026) of the three documented academic positions on how the Great Sphinx eroded and when it was built.
What they do
A descriptive vocabulary, not a promoted theory, that lays out the Schoch (oldest), Reader (middle), and Lehner (mainstream) datings side by side.
How it works
It keeps all three positions active without forcing a choice: Schoch's 10500+ BCE from water erosion, Reader's 4500-2500 BCE early-dynastic date, and Lehner's ~2500 BCE Khafre-era mainstream date; it also separates the quality of Schoch's geology (credentialed) from the credibility of the alt-history operators who cite him.
Why it matters
It's a deliberate 'we don't know yet' stance that resists collapsing the question prematurely, and it stays as background vocabulary rather than feeding the engine's active scoring.
The engine's record — word for word
Engine-novel introduction (Apr 30 2026 V2 alt-history audit). Layer-4 descriptive vocabulary, NOT Layer-1 framework promotion (per Apr 24 2026 layer-promotion discipline). Three documented academic positions on Great Sphinx of Giza erosion + dating: (a) Schoch maximalist — Robert Schoch (Boston Univ geology PhD), water-erosion patterns suggest 10500+ BCE construction during wet pre-dynastic period; (b) Reader middle — Colin Reader (geologist), 4500-2500 BCE construction during early-dynastic transition; (c) Lehner mainstream — Mark Lehner (Egyptologist, AERA dir), ~2500 BCE Khafre-era construction consistent with Old Kingdom chronology. The cluster operates as Apex Superposition register: engine holds all three positions simultaneously without pre-collapse, parallel to Apr 25 2026 Cosmological-Apex denial discipline. Engine relevance: alt-history-operator-class verdicts (Hancock, Carlson alt-history role, Tsoukalos) cite Schoch as data-rigor anchor; Webb Tier-3 source-integrity discipline applies — separate data-rigor verdict (Schoch credentialed Tier-2) from political-distribution verdict (alt-history operators Tier-3). Cluster does NOT enter operational scorecard; remains Layer-4 vocabulary.
