to 'fill the municipal skeleton.'

 - **Person** — an officeholder, filed by the jurisdiction they serve. Federal members are enriched with their bioguide ID, leadership roles, and committee seats.
 - **Body** — an institution: a chamber, committee, or subcommittee. The "repos" of the government-as-code model. Each lists its leadership; subcommittees name their parent.
 - **Candidate** — someone running for office, distinct from a current officeholder. Sourced from FEC filings.
-- **Jurisdiction** — a place with a government, carrying Census demographics. A county's node is its directory `index.md`; a district's is a file under `districts/`.
+- **Jurisdiction** — a place with a government, carrying Census demographics and/or district edges. A county's node is its directory `index.md`; a **city's** is likewise an `index.md` under `municipalities/`, keyed by Census place GEOID and modelled exactly like a county (place + government fused, officeholders nested beneath); a district's is a file under `districts/`.
+- **LegalText** — a single section of statute, filed under its title and chapter. See the [legal corpus](legal-corpus.md).

-The tree is **complete on the map, uneven on the ground**: every U.S. county exists as a node (from Census data), but officeholder depth currently reaches the municipal level only in Florida. An empty directory is not a failure — it is the frontier.
+The tree is **complete on the map, uneven on the ground**: every U.S. county *and* every incorporated municipality (19,513 of them) exists as a node, but officeholder depth is deepest in Florida and thins out elsewhere. A city node with no `people/` yet is a truthful skeleton stub — "governed, not yet mirrored." An empty directory is not a failure — it is the frontier.
 
 A second axis — cross-cutting **issues** that link entities across the tree — is designed but not yet built. See the [roadmap](roadmap.md).
