- AuditTrailPanel SidePanel tab showing the workspace audit ledger from
GET /workspaces/:id/audit with cursor-based pagination (?cursor=, ?limit=50)
- Color-coded event-type badges: delegation=blue-500, decision=violet-500,
gate=yellow-500, hitl=orange-500
- chain_valid=false renders red tamper warning indicator
- Event-type filter bar (All / Delegation / Decision / Gate / HITL) resets
pagination and reloads with ?event_type= param
- Relative timestamps refreshed every 30 s without re-fetching
- Empty state with icon and descriptive copy
- Toolbar Audit button (ledger icon) switches panel to audit tab for
selected workspace, or shows toast if no workspace is selected
- 29 new unit tests across formatAuditRelativeTime, AuditEntryRow, and
AuditTrailPanel component integration suites
- Update SidePanel.tabs.test.tsx for 13-tab count and audit as last tab
- Add setPanelTab to Canvas test store mocks (Toolbar now reads it)
