Implements CFOrchClient with allocate() (sync contextmanager) and
allocate_async() (async contextmanager) for cf-orch GPU resource
allocation. Releases allocation on exit; ignores 404 on release;
raises RuntimeError on non-2xx allocation response. Exports
CFOrchClient and Allocation from circuitforge_core.resources.
Note: async test uses unittest.mock rather than httpretty — httpretty
only patches stdlib sockets and does not intercept httpx async (anyio)
transport.
- dashboard.html: node-centric layout — GPU cards with VRAM bars and
sparklines, active leases table with TTL progress bars, service health
pill, auto-refreshes every 5s via fetch() against the local JSON API
- All dynamic content set via DOM textContent / createElementNS — no
innerHTML with user-sourced strings
- coordinator/app.py: serves dashboard.html at GET / (HTMLResponse,
excluded from OpenAPI schema); HTML read at import time from package dir
- test_dashboard_serves_html: verifies 200, content-type text/html,
and key route markers present
