Hi Joy (Part 1),
I have been contemplating your work in the links you gave. My slip in saying the Hopf spheres I think was my subconscious trying to get my attention: with the particle/anti-particle space being S^0={-1,1} and the space of cyclic waves being S^1, the existence of wave-particle duality seems to be saying the fibre-bundle of the first Hopf sphere. This implies that the first Hopf sphere provides an underlying context for an analysis of Quantum Theory, such as yours.
I think that you short-changed yourself with the meta-principle you gave earlier. Although in mathematical terms the S^7 case (eqn 1.32 of your 9_Origins.pdf attachment) is more general than the S^3 case (eqn 1.28) as S^7 contains S^3 subspace, the assertion of S^7 ONLY precludes the possibility in physics that the two spaces have different origins such that the S^3 is not a physical subspace of S^7. A real sphere example is where the space of the particle symmetries is S^7 - as in my S10 unified field theory (STUFT for short) - and the space of the rotation group is S^3. The rotation group is not a subgroup of the particle symmetries and so BOTH S^3 and S^7 occur as they have a different origin. So the most general statement of your work is not solely in terms of S^7, but S^3 (1.28) AND S^7 (1.32). With the first Hopf sphere providing an underlying context for the wave-particle duality of Quantum Theory, your work would then seem to independently contain S0, S1, S3, S7 and not just as subspaces of S7 (as parallized spheres).
In the context of the spheres being real physical surfaces, the presence of BOTH S^7 and S^3 is critical as the homotopy group for the map S^7 -> S^3 shows that it just involves the S^4 base-space PI_7(S^3) = PI_4(S^3) = Z_2 and gives a chiral non-trivial vacuum looking for all the world like the electroweak vacuum and gives the correct value of the Weinberg angle just in geometric terms. This breaks the symmetry of the S^7 and gives a 3 by 4 table of topological monopoles looking like the particles.
In metric field terms, your eqn 1.53 together with the closure condition of eqn 1.55 specify the spheres S0, S1, S3, S7 as a collection of closed spaces. The principles of GR seem to be captured by the meta-principle: make no preference. This means no preferred speed, ie. the speed of light is always the same, no preferred location (homogeneity) and no preferred direction (isotropy) - these also say no boundary to the space. Applying this no preference condition to the 4 spheres, says all of them. With space being S^3 and the 'particle space' being S^7 the above map S^7 -> S^3 gives a non-trivial vacuum winding and topological monopoles and anti-monopoles with space S^0. The pre-condition of the S^7 -> S^3 map and the lack of an independent S^1 are both addressed by the unification principle: the S^3 of space and the S^7 'particle space' are unified in a sphere S^10 which then has a hole inserted to give S^3*S^7 with the above mapping. In GR, such a scenario would be cyclical between the unified S^10 phase and the 'broken' S^3 * S^7 phase, thus giving the independent occurrence of S^1 in a 10+1 dimensional extension to GR.
This gives the physically-real side I address in extended GR where spheres are spheres, particles are particles and waves are waves.
