StreamableHTTPSessionManager is an ASGI app — it sends its own
http.response.start and http.response.body messages via the scope/receive/send
triple. Wrapping it inside a @app.api_route FastAPI handler causes FastAPI
to try to finalize the response after the handler returns, emitting a
second http.response.start. uvicorn rejects this with:
RuntimeError: Unexpected ASGI message 'http.response.start' sent,
after response already completed.
Every POST /mcp raises, making the server unreachable from any MCP client
(tested with Claude Code 2.x against mcp==1.27.0).
Fix: mount the session manager as a Starlette Mount so it owns the
response cycle directly. Auth middleware still applies because
add_middleware attaches at the app level, wrapping all mounted sub-apps.
- Add docker_container node type (Package icon, sky-blue accent) as child of docker_host
- Parent selector for docker_container filters to docker_host only via nodeType field
- Virtual edge drag-connect syncs parent_id for docker_container <-> docker_host
- Fix setProxmoxContainerMode: remove proxmox-only guard so width/height are properly
set/cleared for all container-capable types (docker_host, vm, lxc)
- Fix handleAddNode: only give group size when container_mode=true, making create
and reload behavior consistent (was giving size unconditionally for CONTAINER_MODE_TYPES)
- Add regression tests for docker_host container mode toggle and docker_container nesting
The native <input type="color"> only supports 6-digit hex, stripping alpha
and forcing background/border/text colors to be fully opaque on edit.
Each color field now shows an opacity slider (0–100%) below the swatch.
Values are stored as 8-digit hex (#rrggbbaa). Existing zones with 6-digit
colors are handled transparently (alpha defaults to 100%).
- colorUtils.ts: hexToRgba / rgbaToHex8 helpers
- GroupRectModal: opacity sliders for all three color fields
- 26 new tests across colorUtils and GroupRectModal
