Review Request: Forty-Five Seconds Only

We refactored Forty-Five Seconds to Make It Clear in response to reviewer feedback. This is the only lab changed to use the new model.

Please review Forty-Five Seconds now. We will update the other labs only after reviewers are happy with this master example.

What Changed in Forty-Five Seconds

• The canonical Activity now reads as a complete learner experience, with preparation, steps, validation, completion criteria, optional extensions, and supporting explanation.
• The lab hub now shows a provenance-aware inventory of tracks, modules, learner materials, additional materials, and availability.
• The Lab Notebook has its own review surface. Content inherited from the Activity is identified and reviewed at the Activity rather than duplicated.
• Each user-facing artifact has a focused review page and its own fingerprinted receipt.
• Final QC is separate from artifact review and requires an independent reviewer.

What Has Not Changed

No other lab has been migrated to this structure. Their current content and review surfaces remain in place while Forty-Five Seconds is under review.

What Reviewers Should Do

Review only Forty-Five Seconds to Make It Clear, including the learner path and the artifact-specific review pages. Please note anything that is unclear, missing, repetitive, or harder to review than it should be.

Once reviewers are satisfied with this example, we will use it to migrate the remaining labs without losing their content or review history.
