v6.0.1: Release Truth Closeout

[flyingrobots]

Outcome

Patch-release closeout is tracked in GitHub, and repo docs agree that GitHub Issues and Milestones are the canonical work tracker.

Current Truth

• v6.0.0 is already published.
• main carries patch-candidate planning and documentation updates.
• Repo-local backlog and goalpost Markdown has been retired as active tracking source material.

Scope

• Confirm release truth in STATUS.md, CHANGELOG.md, and release evidence.
• Keep any remaining patch closeout as GitHub issues, not backlog cards.
• Decide whether this patch ships alone or rolls forward into v6.1.0.

Required Proof

• Local validation for any release-relevant doc or package change.
• Release evidence or explicit carry-forward issue for any deferred item.
