Cosmic-Scale Signatures of the Figure-8 Architecture: Twenty-six predictions are set out, grouped into a cosmic microwave background (CMB) and cosmic‑structure anomaly suite, Earth's geometric position within the figure-8, the engine-cycle and Fibonacci dynamics, a set of quantitative predictions anchored by a single joint observation, a range of cosmological observations, and the framework's own derivation and unification (Phase 11 of the Unified Loop Framework)

Phase 11 collects the cosmic-scale observational signatures of the Unified Loop Framework. Earlier phases established the framework's architecture: the figure-8 atomic primitive with its black-hole-mode and white-hole-mode lobes (Phases 1–2), Russian Dolls scale recurrence (Phases 3–7), cosmic time as field accumulation (Phase 8), and the thermodynamic engine cycle (Phases 9–10). Phase 11 asks what that architecture should leave imprinted on the sky. Twenty-six predictions are set out, grouped into a cosmic microwave background (CMB) and cosmic-structure anomaly suite, Earth's geometric position within the figure-8, the engine-cycle and Fibonacci dynamics, a set of quantitative predictions anchored by a single joint observation, and a range of cosmological observations including the framework's derivation and unification. The strongest, most robust core is the CMB anomaly suite: a family of large-angle CMB anomalies emerging together from a single figure-8 architecture and sharing one axis. The draft is written in the honest posture established by an internal fine-tuning audit: strong results are stated as strong, partial results are stated as partial, and the framework's calibrated and convention parameters are labelled as such rather than overclaimed as derived. The open items (the EDGES cooling magnitude, the KBC void depth, the residual half of the Hubble tension, the cosmic dipole amplitude) are carried openly as the genuine frontier of the work. Independent mainstream observations and analyses that converge with these predictions (high-redshift galaxy maturity, the dynamical role of cosmic voids, direct imaging of the cosmic web, and three independent routes to evolving dark energy) are collected as supportive context, with the limits of that support stated plainly. The signatures examined here are cosmic-scale; atomic-scale, stellar-scale and planetary-scale behaviour is not treated in this phase.
