Detailed Description

The watchlist as the phone packs it, and the reader that unpacks it.

The phone sends the watchlist as one run of bytes with the quotes laid end to end, each carrying its own symbol length. Nothing about it is fixed width, so the reader walks it and checks every step against the length it was handed. The bytes come off a phone, so none of it is trusted.

The packer on the other side is ts/pkjs/wire.ts, and the two have to agree exactly.
