+# Dashboard API and context contract
+
+This document describes the structure of data passed to the index template and returned by the dashboard API endpoints. Cache keys are defined in `dashboard/stats.py`.
+
+## Index page context (server-rendered)
+
+When the index is rendered with full data (e.g. `USE_MOCK_DATA=True` or after JS loads from API), the template receives a context with these top-level keys:
+
+| Key | Description |
+|-----|-------------|
+| `region` | `{ "name": str, "hosts_total": int }` |
+| `pcpu` | Physical CPU: `total`, `usage`, `free`, `used_percentage` |
+| `vcpu` | Virtual CPU: `total`, `allocated`, `free`, `allocated_percentage`, `overcommit_ratio`, `overcommit_max` |
+| `pram` | Physical RAM (bytes): `total`, `usage`, `free`, `used_percentage` |
+| `vram` | Virtual RAM (bytes): `total`, `allocated`, `free`, `allocated_percentage`, `overcommit_ratio`, `overcommit_max` |
+| `vm` | VMs: `count`, `active`, `stopped`, `avg_cpu`, `avg_ram`, `density` |
+| `flavors` | `first_common_flavor`, `second_common_flavor`, `third_common_flavor` — each `{ "name": str, "count": int }` or `None`. The `name` may be a human-readable flavor name or a flavor UUID depending on OpenStack. |
+| `audits` | List of audit objects (see below). For template, `migrations`, `host_labels`, `cpu_current`, `cpu_projected` are JSON strings. |
+| `current_cluster` | `{ "host_labels": str (JSON array), "cpu_current": str (JSON array) }` for embedding in the page. |
+| `skeleton` | Optional boolean; when true, stats placeholders are shown and data is loaded via API. |
+
+## Single audit object (for template / API response)
+
+When serialized for the template or for `api/audits`, each audit has:
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `id` | str | Audit UUID |
+| `name` | str | Audit name |
+| `created_at` | str | ISO 8601 datetime |
+| `strategy` | str | Strategy name |
+| `goal` | str | Goal name |
+| `type` | str | e.g. `ONESHOT` |
+| `scope` | str | e.g. `Full Cluster` |
+| `cpu_weight` | str | Weight parameter |
+| `ram_weight` | str | Weight parameter |
+| `migrations` | str (template) / list (API raw) | JSON string of migration list, or list of `{ instanceName, source, destination, flavor, impact }` |
+| `host_labels` | str (template) / list (API raw) | JSON string of host names, or list |
+| `cpu_current` | str (template) / list (API raw) | JSON string of CPU usage per host, or list of numbers |
+| `cpu_projected` | str (template) / list (API raw) | JSON string of projected CPU per host, or list of numbers |
+
+For the **index template**, `migrations`, `host_labels`, `cpu_current`, and `cpu_projected` are always JSON strings so they can be embedded in the page. For **api/audits**, `audits` are returned with these four fields as JSON strings (same as template). The **current_cluster** in the API response uses raw lists (see below).
+
+## GET /api/stats/
+
+Returns a JSON object with the same keys as the index context, **excluding** `audits`, `current_cluster`, and `skeleton`: `region`, `pcpu`, `vcpu`, `pram`, `vram`, `vm`, `flavors`. All numeric values are numbers; sizes are in bytes where applicable.
+
+## GET /api/audits/
+
+Returns:
+
+```json
+{
+  "audits": [ /* list of audit objects with migrations, host_labels, cpu_current, cpu_projected as JSON strings */ ],
+  "current_cluster": {
+    "host_labels": [ "compute-0", "compute-1", ... ],
+    "cpu_current": [ 30.5, 42.1, ... ]
+  }
+}
+```
+
+Here `audits` use the same serialized form as the template (JSON strings for list fields). The `current_cluster` is with **raw lists** (not JSON strings) so the frontend can use them directly without parsing.
+
+## GET /api/source-status/
+
+Returns:
+
+```json
+{
+  "prometheus": { "status": "ok" | "error" | "mock", "message"?: "..." },
+  "openstack": { "status": "ok" | "error" | "mock", "message"?: "..." }
+}
+```
+
+## Cache keys (dashboard/stats.py)
+
+- `CACHE_KEY_STATS` — stats for `/api/stats/`
+- `CACHE_KEY_AUDITS` — serialized audits list
+- `CACHE_KEY_CURRENT_CLUSTER` — raw current_cluster (host_labels, cpu_current lists)
+- `CACHE_KEY_SOURCE_STATUS` — source status result
