Detailed Description

The forecast strips as the phone packs them, and the readers that unpack them.

Both strips are a short header then a run of fixed-width columns, so unlike the agenda and the watchlist the whole length is known before any of it is read. That makes one check up front enough, where those two have to check at every step, and it is why these two fill the caller's strip as they go rather than handing over a finished copy.

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