Cost

Cost (nav label; screen title "Budgets, quotas & usage") is the Cost Guard cockpit. It shows live and historical LLM spend, per-provider breakdowns, budget configuration, and — on cloud workspaces — plan and invoice context.

Layout

The screen uses a tabbed layout:

• Overview — top-card totals, sparkline (today / week / month), and provider breakdown table.
• Budgets — create, edit, and evaluate spend budgets with alert channels.
• Alerts — muted and active budget alerts.
• Billing — plan tier, invoices, and backend-computed usage state (cloud only; deep-link via tab=billing).

Budgets and alerts

Each budget defines a spend cap and evaluation window. Evaluate runs synchronously against the cost tracker; in-flight runs may not yet be reflected — the UI shows "as of" timestamps from cost.updatedAt.

Reset counters is destructive: it requires confirmation, writes an audit entry, and should only be used after operator review.

Cloud vs self-hosted

On self-hosted desktop installs, billing tabs may show a disconnected state honestly — the UI does not synthesize plan or invoice data. Usage limits on cloud tenants come from usage.state.get (backend-computed; do not recalculate limits in the UI).

Deep links

Commercial notifications can open Cost directly on the Billing tab (tab=billing). The screen consumes one-shot navigation params after mount.
