Section Identifiers
The actId canonical id, the fields that describe a section's place in the hierarchy, and moving from search to full text.

An actId encodes where the section sits (title, chapter, part, section). Because of that, ids should come from the API and not be hand-built from a citation.
- Search or resolve returns an actId.
- GET /us/statutes/section/{actId} returns metadata.
- .../body returns the text.
