Provenance/claims carried created_by/verified_by as {type,id} principal
refs from the service, but the types said string|null and ProvenancePanel
rendered them raw → React #31 crash on every object view. Widen to
string|PrincipalRef|null and add formatPrincipal() (barrel-exported).
Badges: mode-aware semantic tones (mix toward --foreground) so success/
warning/info/danger text clears WCAG AA on the subtle tint in BOTH light
and dark; Active badge 2.81→5.25/5.67:1. SensitivityBadge renders nothing
for an unset level (objects inherit from their collection) instead of a
misleading "—" pill. TierBadge tolerates an unknown tier.
Accessibility: Badge gains ariaLabel (screen readers announce the meaning,
not just the terse label); Field links label↔control via htmlFor + useId
and wires aria-describedby to the hint; OwnerToggle gets aria-pressed;
icons aria-hidden.
First-run: CollectionForm leads with Name and auto-derives the Identifier
(was slug-first); placeholder text uses --muted-foreground. Drop the
Sparkles "AI-magic" icons from the review empty state and the agent tier
badge (Inbox / Bot instead), per the no-magic-framing principle.
