[Data Source] Build Durham County BOCC agenda, minutes, and vote scraper

[ThatXliner]

Summary

Add Durham County Board of Commissioners (BOCC) meetings as the county-level half of the Durham local-information pilot.

Official sources

• Schedule: https://dconc.gov/Board-of-Commissioners/Meetings-and-Announcements/Meeting-Schedule
• Archive: https://dconc.gov/Board-of-Commissioners/Meetings-and-Announcements/Archived-Agendas-and-Minutes
• Meetings/video: https://www.dconc.gov/i-want-to/see-commissioner-s-agendas-and-meetings

The document-heavy County archive is separate from the City OnBase source and should be tested independently.

Scope

• Discover the CivicPlus/archive pagination request; do not crawl thousands of unrelated documents.
• Enumerate regular/work/special sessions, public hearings, cancellations, and amendments.
• Parse agenda/minutes PDFs into agenda items, consent items, hearings, motions, outcomes, and named roll calls where present.
• Preserve bilingual documents without mixing Spanish into English extraction.
• Match official video records deterministically by meeting date.
• Map through a Durham County adapter to the local-government contract.
• Add caching/checksums, source-version tags, polite concurrency, OCR diagnostics, and idempotent upserts.
• Test a regular session, work session, cancellation, and amended document.

Acceptance criteria

• Backfill 12 months with agenda items and final actions under the same meeting.
• Replaced PDFs update rather than duplicate.
• Every record cites the official County page/document; one parse failure cannot abort the run.

Outreach Tracker
