Portfolio heatmap

Using the ScalePad MCP, gather compliance health for every ControlMap client and every framework assigned to them. Build an interactive artifact:
- Heatmap: clients as rows, frameworks as columns, cells colored by % compliant (blank where not assigned)
- Sort by lowest score, most open risks or oldest evidence
- Click a client to see its top 3 gaps and overdue action items
- A summary row: average compliance, clients under 50%, total overdue action items

Use only real data and show when it was pulled.

How to work with the ControlMap API (ScalePad MCP):
- Find the client with GET /controlmap/v1/clients/health and use its tenant ID (for example "dundmif") in every request. Some clients have no UUID.
- Send the header Content-Type: application/json on every POST, PUT and PATCH, including searches.
- Use page_size of 50 or less and follow next_cursor. The "fields" parameter is ignored, so responses are large.
- Judge controls by "status", not the "compliant" flag. Objective lists include sub-objectives, so take totals from objective_summary.
- Use framework-level scores and labels. The overall score_label on client health can be wrong.
- Older policy sections may be URL-encoded twice: decode them and use the highest version of each section.
- If a call returns 502 or fails to connect, wait a few seconds and retry once. If it still fails, tell me exactly which data is missing.
