Big questions:

• Show that every pro-p group which may be completed into a 1-cyclotomic oriented pro-p group satisfies the (strong?) n-Massey vanishing property for every n > 2.

• Show that every pro-p group G which may be completed into a 1-cyclotomic oriented pro-p group satisfies a Tits' alternative: namely, either G is p-adic analytic (or locally uniform, or solvable... these properties are equivalent in this case!), or it contains a free non-abelian subgroup (cf. Question 4.7 in «Galois-theoretic features for 1-smooth pro-p groups», Canad. Math. Bull. 2021 - in fact it is equivalent to consider the same question for an absolutely torsion-free pro-p group).
