Draft Lab Closeout QA — 2026-08-07

Result

All 18 Draft Activities and 18 Draft Notebooks passed rendered checks at desktop and narrow-mobile widths. All seven declared interactives loaded without console warnings or errors, linked to their own review surface, and completed a representative interaction.

One mechanical defect was found and corrected: the mobile Back/Next controls in Build a Safe Text-to-Speech Skill used sticky positioning and covered step content. The controls now remain in document flow, the stylesheet URL is cache-busted, and a regression test protects the behavior.

No instructional content, lifecycle state, review decision, video, or governance contract changed during this sweep.

Expected open package states

Six Draft packages remain explicitly incomplete because their required walkthrough video is absent: The Disclosure Ladder, From Inspiration to Invention, Module to Interactive Single-Page Application, Reduce the Precision, The Restaurant Test, and What Does the Tool Need? This QA result does not change those package states.

The 14 Placeholder labs remain visible outside the Draft review catalog and were not expanded or reviewed in this checkpoint.
