Preprint of a manuscript currently under journal review. The documented geometry of the Great Sphinx realises a single proportional module in two orientations: transverse dimensions follow an integer grid generated by (7, 11); forepaw span and head height follow the same grid with the generators' roles exchanged; the exact identities implied by that exchange hold in the stone to better than 0.16%. The paper builds the statistical machinery such claims require — a canonical classification of 1,050 composition rules, a calibrated family-wise exceedance statistic (1.83 × 10⁻⁵ across 600,000 null geometries), negative controls, and a 36-specification multiverse — and reports five chance-level tests of a coordinated pyramid programme alongside one suggestive seked-level correspondence. It closes with a prospective, frozen morphological prediction: a scaled chest concavity of 8.0–8.7 cm, adjudicable with existing 3D survey data. Files: full manuscript (PDF); S1 Code — complete fixed-seed reproduction code (every principal result reproduces from these files alone); S2 Data — all dimensional data with page-level provenance; S3 Protocol — the frozen prediction protocol, deposited here to establish a public, dated record prior to any adjudication.
