Three new source datasets from Atlas, committed as-is before any build:
fec_candidates.jsonl 2,494 2026 federal candidates (officeholders.fec_data)
acs_county.jsonl 3,231 Census ACS 2023 by county (~100 dup keys to dedupe)
acs_cd.jsonl 363 Census ACS 2023 by congressional district
A new axis for the mirror: who is running (candidates) and the
demographics of each place (ACS). Keyed on fec_id / state+district /
county_fips — no person links yet. Raw first; the build into Candidate
and Jurisdiction entities follows.
