Review: Checking Groups

## Spark

Marked Finished in the Media Log during the 2026-08-08 digest check-in, one of
four completions that week.

## Why it could be interesting

Unsettled — the take comes first and I don't have it yet. The title suggests
something technical rather than narrative, which would make this a different
kind of review: the question becomes whether it taught something that changed
practice, not whether it was worth an evening.

## Open questions

- [ ] What is this, and what was the reason for picking it up? (Establish before
anything else.)
- [ ] Recommend it or not, and to whom?
- [ ] If it's technical: did anything from it actually land in how something
gets done now? A review with no changed practice is a summary.
- [ ] Is there an argument here, or should this stay a Media Log entry?
