Turn groups of cards into PAO composites, place each composite at successive loci in a palace, then walk the palace to read the order back.

* The full method, end to end: shuffle, encode triples, place, recall, decode, restore. *

The pipeline, end to end:

1. Encode — flip the deck in order, fusing each group of three cards into one Person-Action-Object image.
2. Place — drop each composite at the next locus of a rehearsed palace.
3. Recall — walk the palace, decode each composite back into its three cards, and name them in sequence.

Two tools, one pipeline: PAO compresses and encodes, the palace stores and orders.
