Context Cleanup — Lab history & changelog

Return to lab

Origin story

This lab was created around a focused learner practice: Context is not automatically useful because it is available. Learners practice finding the current source of truth, distinguishing stale or untrusted material from useful support, and making an explicit cleanup decision before any downstream work begins. Its original Draft package brought the activity and supporting materials together for review before the canonical lab-page migration.

Change log

2026-09-06

Bound the Lab Notebook to the canonical Activity’s completion and extension criteria, standardized result criteria as checklists, and synchronized the Notebook from that source.

Marked the Gallery Coming soon because it does not yet contain a linked example with an explicit provenance statement.

Moved learner-facing metadata, materials, relationships, and activity content into lab.md; retained this README as the lab origin story and change log.
