In brief

Snapshot overview

Methods & Provenance

How this edition is made

Pipeline & integrity
1 · CollectScheduled scrapers and agency feeds gather public records from crescentcity.org, Del Norte County, the Harbor, alert APIs, and meeting video channels. Every fetch is recorded with its source URL, check time, and operational state.
2 · VerifySource health checks classify each feed as healthy, empty, unavailable, or stale. Unavailable sources are never converted into calm results; an empty feed means the check succeeded but found nothing.
3 · Summarize & tagOptional language models write short summaries and tags over collected material. Generated outputs carry their provider and model. Check the linked source before relying on them.
4 · ExportThe atomic exporter builds this static artifact from one immutable snapshot envelope. Counts below are injected at export time from that exact manifest, so this page cannot drift from data/snapshot.json.

Model summaries and tags can contain errors or unsupported details. Automated checks do not certify factual accuracy; verify claims against the linked original sources. Chat history, request logs, vector indexes, credentials, and Triplicate article content are excluded from every public export.

Schema versioning: the snapshot envelope carries schemaVersion 1.0.0; geo artifacts carry crescent-city-geo-intel/v1 plus view crescent-city-geo-view/v1; events carry crescent-city-events/v1. Additive changes keep older consumers working.

What is this?

The Subscribe · .ics link downloads an iCalendar file of the community calendar. One-time setup, then your calendar app keeps the entries:

  • Google Calendar: open Settings → Add calendar → From URL, paste https://quadruplicate.org/data/events.ics, and save. Google re-checks the file periodically.
  • Apple Calendar (macOS/iOS): open File → New Calendar Subscription (or Settings → Calendar → Accounts → Add Account → Other → Subscribe to Calendar on iOS), paste the same URL, and confirm.
  • Other apps: any client that supports “subscribe to calendar by URL” works with the same address; the direct file download is a fallback for one-time imports.
