3x3 — Blindfolded

M2 for edges, Old Pochmann for corners, Speffz letters.

Checked by simulating 500 complete blind solves using these setups and algorithms — all solved. One fix from your notes: edge B's setup.

Order

    Letters

    Edges — buffer U / K (DF)
    Corners — buffer A / E / R (UBL)

    buffer (never a target) opposites: C↔W, I↔S (swap them on every 2nd edge target)

    Edges — M2

    Setup, M2, undo the setup. Letters marked “special” have their own algorithm.

    Parity

    Odd number of edge targets? After the edges, do either of these.

    Corners — Old Pochmann

    Setup, swap, undo the setup.
