almanacA0a — the centre of the even hybrid family quantum GL(1)

The pilot edition · a closed record in three layers

This is a complete record of one small mathematical result in three layers — an informal proof, a computer program, and a machine-checked formal proof — together with a per-claim account of what actually warrants each one.

What is in this almanac

Everything below is in this package and works offline. Read the mathematics first if that is what you came for; the three layers and the apparatus that joins them are underneath it, and the twelve statements themselves follow further down.
