thurview explain

A review explains a change. An explainer explains a codebase, or one subsystem of it, at a single pinned commit, so the reader can see the architecture well enough to spot design problems themselves.

Same engine, different unit. It shares anchors, peeks, the map, threads, revisions and the publish → wait → answer loop with the thurview skill's review. It has no diff, no commits and no interface delta, because those are claims about a change and there is no change. Where a review shows the interface delta, an explainer shows coverage: what it examined at that commit, and what it did not.
