## Four seats

Executives: brand, conversion, and governance risk that source correctness alone does not catch.

Designers and QA: verify the shipped UI matches intent, with evidence you can replay.

Engineers: see what the running PR head actually does before you merge, including agent PRs.

Engineering leads: confidence and efficiency at the PR boundary, without a manual QA session on every change.
