Atlas resolved every existing municipal officeholder to its Census place
GEOID at the source (PostGIS). build.py now prefers that exact geoid over
the name-based fuzzy resolver, so filled cities land on their node exactly
rather than by 98.8% name match. Resolved 2,217 -> 2,224; dedup against the
skeleton tightened (a few fuzzy mismatches now collapse correctly).
Note: this is the GEOID *backfill*, not the *fill* — zero net-new
officeholders; the 17,286 empty skeleton cities remain empty. Nationwide
municipal officeholder acquisition is a separate, per-state source problem.

The Code empowers the executive branch, but the mirror only had legislative
Bodies — every authority reference pointed at nothing. Fixed by minting the
executive branch from the Code's OWN enumerations: 15 Cabinet departments
(5 U.S.C. § 101) + 21 Executive-Schedule Level I offices (§ 5312), 42 Body
nodes under us/executive/.
Then the axis: scripts/extract_authority.py matches named office/department
references across all 59,740 sections (guarding against Deputy/Assistant/Under
subordinates) and emits data/section_authority_edges.jsonl — 27,804 edges from
17,031 sections (28.7% of the Code) to the offices they empower. build.py
renders reciprocal 'empowered by' links on each office node; the section files
are never touched. Now: click the Attorney General, see all 2,386 sections that
vest authority in it.
Named references only in v1 (cabinet-level). Deterministic; body.schema
classification enum extended (executive-department/-agency/-office); make check
green at 105,746 records.

A city was a string buried in a job title; now it is a node. build.py
mints all 19,513 incorporated Census places (CDPs filtered out — they
are statistical, not governed) as Jurisdiction nodes keyed by place
GEOID, modelled exactly like a county: place + government fused, with
officeholders nested beneath, not a separate Body.
Officeholders join to their city by a name+state match (county-hint
disambiguated) off the same jurisdiction_label that city_slug uses for
placement, so node and people co-locate by construction. 2,229 cities
are filled today (2,217 GEOID-resolved, a 98.8% join); the other 17,289
are truthful skeleton stubs — 'governed, not yet mirrored' — the same
discipline as the nationwide county skeleton.
Deterministic (byte-identical on rerun); classification enum extended
with city/town/village/borough; validation green at 57,185 records.

The Code genuinely contains distinct sections sharing one number (two
5 U.S.C. 5757, two 10 U.S.C. 130g, two 5 U.S.C. 3598). The ingest
silently overwrote the first with the second — data loss in a mirror.
Later occurrences now get a deterministic -N suffix.
The 'elections' tag was hardcoded from the Title 52 seed; it now
applies only to Title 52, with a per-title EXTRA_TAGS map. Makefile
gains TITLES override: make legal-us-code TITLES="7 10".

Fourth lens on the Board, coloring each county by the D/R balance of the
state + federal representatives who cover it — the offices that are
actually partisan (99% D/R coverage vs ~0% for nonpartisan local seats).
Pipeline (build_viz.py):
- Carry each district rep's party alongside their name through the
county<->district edge mapping.
- Per county, tally reps by party over districts covering >=5% of its
area (slivers excluded), and store lean = (R-D)/(R+D) in [-1,+1] plus
repD/repR counts. Head-count, not area-weighted, so the number matches
the readout and isn't skewed toward large rural districts. 3130/3131
counties resolve.
Board (board.html):
- "Partisan lean" lens with a diverging blue<->grey<->red ramp (centered
at 0, skipped in the percentile-rank machinery the other lenses use).
- Diverging legend (More Democratic / More Republican).
- Readout gains a Representation row (e.g. "8 D · 3 R D+45").
- Drill-down district reps get a D/R party badge.
Verified in preview: no console errors; Manhattan -1.0 (21D/0R), LA -0.46,
Palm Beach even (3D/3R), Loving TX +1.0; readout, color, and badges agree.

Surfaces the new graph layer on the Board. build_viz.py resolves each
county's district edges to their current representatives (via
build.person_district_node) and injects a per-county `districts` block into
CDETAIL; board.html renders "In Congress / State Senate / State House"
sections in the drill-down, each rep with their district and % of county
covered. County detail now spans 3,221 counties (was 1,049) since every
county with district edges gets a drill-down, not only those with local
officials. Deterministic (board.html byte-identical on rerun).

The first edges in the repo. Every US county now links to the districts it
sits in, weighted by area overlap, and every legislator links to the district
they represent — county → district → representative, traversable.
Data (PostGIS, no Atlas dependency — computed directly from geometry):
- data/county_district_edges.jsonl — 16,328 weighted edges. area_weight =
ST_Area(ST_Intersection(county, district))/ST_Area(county) over ST_MakeValid
Census TIGER 2024 geometries, overlaps <0.5% dropped. Uses area-intersection,
NOT centroid-in-polygon, so urban districts that carve through counties
(e.g. GA CD-5 / Atlanta across Clayton+DeKalb+Fulton) are captured, not
silently dropped. Per-county weights sum to ~1.0 per district type.
build.py:
- ~6,896 new district nodes: 435 CD (ACS demographics where available; sparse
for the 8 states missing from acs_cd) + 4,927 state-house + 1,897 state-senate
(geometry-only). GEOID/number-keyed, stable.
- county index.md gains a `districts:` block (frontmatter) + a ## Districts
section (body links, so link-integrity checks them).
- legislators + US House members gain `represents:` pointing at their district
node; edge stored once on the person, inverse left to the view.
- schemas/jurisdiction: classification enum + chamber/districts fields.
Honest gaps (logged, not hidden): ID + NH have no state-house geometry, so
their house districts get nodes (represents resolves) but no county edges;
CD nodes for acs_cd-missing states are demographically sparse.
Deterministic (byte-identical rebuild); validate.py passes 26,617 records,
link-integrity clean (every district/represents link resolves).

The Board is a self-contained Artifact, so its county data is INLINED
(const D / const CDETAIL) — the standalone county_*.json companions are not
read by it. build_viz.py was only writing those companions, so the rendered
Board kept showing the pre-crosswalk state (67 counties). Now build_viz.py
injects the fresh data straight into board.html's three marked const lines,
and the header stats read from an injected TOTALS object instead of being
hardcoded (so they can't go stale — the original 11,285 drift).
- scripts/build_viz.py — inject_board(): rewrite const D / CDETAIL / TOTALS
in board.html; load candidates + acs_cd for the totals
- viz/board.html — header driven by TOTALS; inlined data refreshed
(county drill-downs 67 → 1049 counties; e.g. Fulton GA now shows all 7
metro mayors)
Deterministic: board.html is byte-identical on rerun. Verified live —
header 13,329/2,494/3,131/363, Fulton/Bastrop drill-downs render nested
municipals.

build_viz.py was resolving officials to counties without the place→county
crosswalk, so only FL's 67 counties had rosters. Factor the resolver out of
build.py into a shared build.place_resolver() and use it in both, so the
Board and the tree agree by construction.
- scripts/build.py — extract place_resolver(); main() now calls it (tree
output byte-identical, refactor is behavior-preserving)
- scripts/build_viz.py — resolve via the shared resolver
- viz/county_data.json, viz/county_detail.json — regenerated
County drill-downs: 67 → 1049 counties with rosters; officials mapped
5184/5226 (42 county-unresolvable, tree-only). Deterministic.

Pull Atlas's place→county crosswalk (Census TIGER 2024 places × county
geometries, 32,041 places) into the build as a committed raw input, and
use it to resolve municipal officeholders whose county was unknown.
- data/place_county_crosswalk.jsonl — new raw input (place_geoid → county_geoid)
- build.py — place-name+state → county_geoid → ACS county slug as a fallback
in county_slug(); city_slug() generalized to non-FL bare place labels
- data/sources/sources.yaml — provenance entry for the crosswalk
_unresolved municipals: 1919 → 58. The remainder are genuine: CT planning
regions (post-county), county-level rows mislabeled municipal upstream,
consolidated city-counties (null label), Wikidata-QID placeholder names,
and ambiguous same-name places — left unresolved rather than guessed.
Join key is county_geoid (5-digit FIPS); the directory slug is taken from
the ACS county node so municipals nest under the exact existing county dir.
Deterministic (byte-identical rebuild); validate.py passes 19,721 records.

Re-exported directly from Postgres (10.0.0.116), not Atlas's introspection,
which under-reported the roster (its v3 export had 11,473, missing the
restored Florida League of Cities municipal set). Live DB current tenures:
state 7,561 · municipal 4,009 · county 1,217 · federal 542.
- build.py now reads officeholders-v3.jsonl (was v2); dataset vintage 2026-07-04
- fixed one corrupt start_date at source-export (21021-12-03 -> 2021-12-03,
Lorraine Borowski, Mayor of Decorah IA)
- scripts/build_viz.py: committed, deterministic generator for the Board's
county_data.json / county_detail.json (previously built ad-hoc)
- generate_changelog.py: ignore files whose only change is the vintage stamp,
so the diff reflects government change, not re-export bookkeeping
Person files 11,285 -> 13,329. Non-FL municipal officials (1,903) are in the
tree but not yet county-mappable (place->county crosswalk still NULL).

The diff is the product — now literally. generate_changelog.py reads a
git diff of the entity tree between any two refs and says, in plain
language, what changed in the government: entities added / modified /
removed, grouped by type and by jurisdiction, dated from the commit.
CHANGELOG.md is seeded from the real history so far:
- initial load: +11,285 people across 51 states
- institutional gap: +233 bodies, ~532 people enriched
- elections + demographics: +2,494 candidates, +3,494 jurisdictions
(TX +541, FL +396, CA +341 ...)
On an initial load every entity is an addition; on a re-sync of the same
source, only real government changes will surface — which is the whole
point. When nothing changed, it says so.
make changelog [BASE=.. HEAD=..]. No third-party deps.

The README claimed 'validated by JSON Schema' — now it is true.
/schemas holds a JSON Schema for each entity type (Person, Body,
Candidate, Jurisdiction): a stricter profile over OKF's permissive
base, tolerating unknown keys by design.
scripts/validate.py checks all 17,506 files with no third-party deps
(hand-rolled frontmatter parser + minimal schema engine):
1. OKF conformance — every file has frontmatter with a non-empty type
2. Schema conformance — required fields, property types, enums
3. Link integrity — internal /-rooted links resolve
Non-zero exit on failure, so it is a CI gate. Verified with a negative
test: it catches bad enums and dead links. All 17,506 files pass today.
Makefile ties it together: make build / validate / check.

Two new entity types, built deterministically from the raw exports:
Candidate (2,494) — 2026 federal candidates as files under
us/states/<st>/candidates/, with office,
district, party, incumbent/challenger stance,
campaign committee, FEC id.
Jurisdiction (3,494) — demographic nodes carrying ACS 2023 data:
3,131 counties (deduped from 3,231 mixed-format
fips keys) + 363 congressional districts.
This completes the county skeleton nationwide: every US county is now a
browsable node with population, income, poverty, race, education and
housing — even where no officeholders are mapped yet. In Florida the
county index.md merges into the existing dir and reports its officeholder
count alongside demographics (St. Lucie: 33 officeholders + ACS profile).
build.py now reads seven raw inputs in one deterministic pass
(byte-identical on rerun). The mirror now answers: who holds power, who
runs this institution, who is running, and what each place is made of.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The seat data answered 'who represents this place?' but not 'who runs
this institution?' — the Speaker of the House existed only as the rep
for LA-4. This adds the missing axis of institutional power.
New Body entities (233): the U.S. House, U.S. Senate, Executive Office,
49 committees, 181 subcommittees — each with its leadership.
Federal people (532/542) enriched with bioguide IDs, leadership roles,
and committee seats, reconciled from congress-legislators by name.
Mike Johnson is now Speaker of the House, not just LA-4.
Sources ingested directly into the repo (repo-canonical): Atlas
supplied bodies/leadership/committee_memberships via congress-legislators,
committed raw in data/. build.py supersedes convert_officeholders.py and
reads all four inputs in one deterministic pass (byte-identical on rerun).
The 10 unenriched federal records are a finding, not a bug: vacancies,
the President, and ~5 seats where Atlas's roster disagrees with the
authoritative current roster — model-vs-reality discrepancies to surface.

One record, one file. The jurisdiction tree is now real:
us/people/ 542 federal
us/states/<xx>/people/ 7,561 state
us/states/fl/counties/<c>/people/ 1,058 county
.../municipalities/<m>/people/ 2,124 municipal (67 FL counties)
Each file is OKF markdown + YAML frontmatter: fixed key order,
field-level source provenance, Atlas UUIDs for round-tripping,
deterministic paths and slugs. Converter passes the determinism
test: two runs, byte-identical tree.
Generated by scripts/convert_officeholders.py from
data/officeholders-v2.jsonl (unchanged).
