N opens a manual finding on whatever is selected in the browser pane. The scope control is the important part: this page only binds the finding to one URL, while every page with this element matches it across the sample by selector, so a footer problem is one finding rather than forty-two. Scope is set once at creation and shown on the card, because changing it later would silently rewrite the counts in a published version.
The two-state block and the amber viewport frame say which one is showing at all times. This is the one place amber describes a mode rather than a change, because acting on the wrong one silently produces evidence that does not match the version record.
Triage is the bulk of the working day, so status writes, navigation, evidence, push and recheck all sit on single keys — and every one of them is undoable, because rapid keying guarantees misfires.
Annotating during a live session triggers a visible micro-capture. A finding never rests on what someone remembers seeing.
