076: After Scrolled is not read: highlights to the vault, statuses from reading, what you read, the meter's words, the billing decision, a shared vocabulary, more links

The plan in the article Scrolled is not read (v0.12.85), in order; each step becomes its own card when it starts.

1. Highlights travel: a highlight kind in the pane's notes, to the vault and, when sent, the lane.
2. Your desk reads the two measures: Done when read; Skimmed as a status.
3. What you read, for real: the account page by article, scrolled and read and highlights (the prototype in the article).
4. The meter's words: "scrolled" where the foot block says "read", and the read measure beside it (sg-meter v1.5).
5. A fortnight of the owner's reading in sgit.reading.v1, then the billing decision: scroll, read, or scroll settled by read.
6. A shared vocabulary of concepts across the article graphs (1,788 labels, 32 shared), kept by the Librarian in the findability file.
7. Links: more, and How this connects, drawn in the reader's browser from the published data.
8. A summary of the reading records in the vault.
