+And the axes now cross: **27,804 authority edges** link 17,031 U.S. Code sections to the executive offices they empower, so the Attorney General's node lists every one of the 2,386 sections that vests authority in it. Law and power are no longer separate piles.

 - **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.
+- **Body** — an institution: a chamber, committee, subcommittee, or an executive department/agency/office. The "repos" of the government-as-code model. Executive Bodies under `us/executive/` are minted from the Code's own enumerations (5 U.S.C. §§ 101, 5312) and carry the **authority axis** — reciprocal links to the U.S. Code sections that empower them, from `data/section_authority_edges.jsonl`.
 - **Candidate** — someone running for office, distinct from a current officeholder. Sourced from FEC filings.
 - **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 federal government, structurally** — every member of Congress, the chambers, 49 committees and 181 subcommittees with their leadership, and every member's committee seats.
 - **The nationwide county skeleton** — all 3,131 U.S. counties as demographic nodes, plus all 435 congressional districts (Census ACS demographics on 363).
 - **The authority layer** — every state legislative district (4,927 house, 1,897 senate) linked county↔district↔legislator, nationwide.
 - **The municipal layer** — every incorporated place in the country (19,513 cities, towns, villages, boroughs) as a first-class Jurisdiction node keyed by Census place GEOID, modelled like a county (place + government fused). 2,229 are filled with their officeholders today (2,217 GEOID-resolved off a 98.8% name→GEOID join); the rest are truthful skeleton stubs — "governed, not yet mirrored" — waiting for depth, the same discipline as the county skeleton.
 - **The complete U.S. Code** — every section of all 53 populated titles (Title 53 is reserved), 59,740 per-section records, mirrored from the official OLRC USLM XML at release point 119-100, uniform edition end to end, with manifests and checksums.
+- **The authority axis (v1)** — the executive branch minted as nodes from the Code's own enumerations (15 Cabinet departments from 5 U.S.C. § 101, 21 Level I offices from § 5312), and **27,804 edges** linking 17,031 sections to the offices they empower. `scripts/extract_authority.py` → `data/section_authority_edges.jsonl` (a committed input, like the district edges); reciprocal "empowered by" links render on each office node. Named references only for now (cabinet-level); relative refs ("the Secretary") and the agency long tail are next.

 - **Self-updating mirror** — the `make check` GitHub Action now guards every push; next is the scheduled job that pulls a fresh Atlas export, rebuilds, and commits the changelog automatically. That is the point where the mirror maintains itself and the daily civic changelog becomes real (the first *re-sync* diff, where only genuine government changes surface).
-- **The Code as a living diff** — the whole Code is in; the next lever is re-syncing it at each new OLRC release point so amendments surface as diffs (a new public law becomes a visible change to the affected sections), and linking sections to the offices and bodies they empower (the authority axis).
+- **Deepen the authority axis** — v1 links cabinet-level *named* references. Next: resolve relative references ("the Secretary", "the Commission") via each title's definitions section; mint the agency long tail (~600 more offices the Code names — EPA, OPM, FCC, GAO…); attach current occupants (a Person for the sitting Secretary, from Atlas); and render the reverse edge on the section files themselves.
+- **The Code as a living diff** — re-sync the Code at each new OLRC release point so amendments surface as diffs: a new public law becomes a visible change to the affected sections.
 - **The demographic choropleth** — the Board already has ACS data for every county; shade the map by population, income, and poverty, turning it from a coverage indicator into an instrument.
 - **Fill the municipal skeleton** — the 19,513 city nodes exist; 2,229 carry officeholders. The work now is depth: pull municipal officeholders for the next states (Texas, California, Ohio all have a spine already), each a diff against a node that's waiting. Municipal ACS demographics would enrich every city node the way ACS already enriches counties.
 - **State and local bodies** — Bodies (as distinct institution files) currently exist only at the federal level. Mint them for state legislatures and, following the municipal layer, county commissions where they warrant a Body of their own.
