Source Register
Compiled September 27, 2026 from the packaged dataset. Research consultation dates are listed per source; compilation does not imply fresh verification.
Official public sources support the paraphrased profiles and relationships. Entity and edge source IDs are recorded in dist/data.json. Direct retrieval of some pages timed out; search-indexed official text was also used. A review date records consultation, not guaranteed freshness or successful live-link testing.
Reading relationships
Appointment, confirmation, governance, advisory, budget process, legal advice, department structure, and administrative support describe different institutional relationships. Dashed interpretive connections are editorial links across related responsibilities, not claims of formal authority. Rings classify institution types, not a universal reporting hierarchy.

Dated facts and review queue
The elected roster was posted 2026-10-05 and checked 2026-10-14. Park acreage, trails, and the more-than-500-sites description come from May 2025 assessment materials, not a new 2026 inventory. Neighborhood Council, Community Plan, and library counts are informational-page snapshots reviewed September 18, 2026. Budget links point to the CAO document index and Council File 26-0600; this mockup does not claim a verified spending total.
Before wider release: check formal edges against specific Charter provisions; recheck officeholders and outgoing links; expand County and municipal coverage without conflating separate governments; use consistent fiscal years and fund definitions for any added spending data; and consult CivLab on a compatible entity schema.
