Lightweight data policy: checked defaults + correction workflow

[dlebauer]

Goal

• Make it clear to users what is included by default (especially checked) and how to report corrections.

Tasks

• Decide and implement default behavior:
  • Exclude checked = -1 from shipped datasets.
  • Include checked = 0 and checked = 1 in shipped datasets.
  • Preserve the checked column so users can filter.
• Add a short user-facing note in README (or a dedicated NEWS/README section) that:
  • explains checked at a high level
  • requests users file GitHub issues for:
    • data corrections
    • evidence-backed “this record is verified/checked” reports
• Add an ISSUE_TEMPLATE:
  • “Data correction”
  • “Verified/checked record report”

Acceptance criteria

• README includes a clear, concise data-policy section for checked and how to contribute corrections.
• Issue templates exist and are discoverable from the GitHub UI.
• Shipped data excludes checked = -1 (validated by a simple test or check).

Non-goals

• No long-form policy documents.
