More components
The remaining building blocks the Hub needs: a hierarchy tree, version diff, first-run coaching, contextual help, and a batched notification digest. Each leans on the same tokens and tone as the rest of the system.
Tree / hierarchy
Program → obligation → evidence. Expandable, keyboard-navigable, for taxonomies and the evidence binder. Click a parent to toggle.
Diff / comparison
Policy v6 → v7, line by line — what an examiner asks for when a procedure changes.
Coach mark
First-run guidance — a spotlight on one feature at a time, dismissible, progress shown. Never more than a short tour.
This is your Radar
Incoming regulatory changes that touch your programs land here first — with the why-it-matters already worked out.
Contextual help
A quiet "?" beside a term that needs a sentence of explanation — help where the question is, not in a separate manual.
Notification digest
Batched, grouped, calm — the opposite of a firehose. Grouped by program, newest first.
