# Ops Hub Activity-Core Widget Mapping

Date: 2026-06-15

Workplan: `IHUB-WP-0022`

## Purpose

`OPS_HUB_WIDGET_MAPPING` tells activity-core which Inter-Hub widget receives
each ops evidence event. The value must be non-secret JSON. It may contain
Inter-Hub widget UUIDs and logical references, but it must never contain
`OPS_HUB_KEY` or any operator credential.

Activity-core currently only checks that a mapping value is present before
returning `inter_hub_sink_deferred`. This document defines the contract that
the future Inter-Hub submission implementation should parse.

## Versioned Shape

```json

    },
    "services": {
      "state-hub": {
        "widgetRef": "ops:service:state-hub",
        "widgetId": "<uuid>"
      }
    },
    "endpoints": {
      "gitea:gitea-oci-registry": {
        "widgetRef": "ops:endpoint:gitea-registry",
        "widgetId": "<uuid>"
      }
    },
    "accessPaths": {

      }
    },
    "backups": {
      "gitea:database:gitea-db": {
        "widgetRef": "ops:backup:gitea-db",
        "widgetId": "<uuid>"
      }
    },
    "drift": {
      "gitea:gitea-oci-registry": {
        "widgetRef": "ops:drift:gitea-oci-registry",
        "widgetId": "<uuid>"
      }
    }
  }
}
```

## Selector Rules

Activity-core should choose a widget in this order:

1. If the evidence payload carries a `widget_ref` and that reference exists in
   the mapping, use it.
2. For `ops-service-observed`, use `services["<service_id>"]`.
3. For `ops-endpoint-verified`, use
   `endpoints["<service_id>:<endpoint_id>"]`.
4. For `ops-access-path-checked`, use
   `accessPaths["<service_id>:<access_path_id>"]`.
5. For `ops-backup-verified`, use
   `backups["<service_id>:<backing_store_ref>"]`.
6. For `ops-inventory-drift`, use
   `drift["<service_id>:<inventory_object_id>"]`.
7. If no entity-specific widget exists, use the event's aggregate widget.
8. If neither an entity-specific nor aggregate widget exists, skip Inter-Hub
   submission with a non-secret result that names the missing selector.

## Bootstrap Widget Names

The initial aggregate widgets should be seeded before activity-core is pointed
at Inter-Hub:

| Widget ref | Widget type | Suggested name |
|---|---|---|
| `ops:service:aggregate` | `ops-service-card` | Ops Service Evidence Intake |
| `ops:endpoint:aggregate` | `ops-endpoint-card` | Ops Endpoint Evidence Intake |
| `ops:access-path:aggregate` | `ops-access-path-card` | Ops Access Path Evidence Intake |
| `ops:backup:aggregate` | `ops-backup-card` | Ops Backup Evidence Intake |
| `ops:drift:aggregate` | `ops-drift-card` | Ops Inventory Drift Evidence Intake |

Per-entity widgets may be seeded later without changing the event contract.
When a per-entity widget is added, update the mapping and keep the aggregate
widget as the fallback.

## Compatibility Rules

- `version` is required. Reject unknown major versions.
- Consumers must tolerate additional fields.
- Widget UUIDs may rotate, but `widgetRef` values should remain stable.
- Removing a widget mapping is a breaking change for that selector unless the
  aggregate fallback remains present.
- Mapping updates must be deployed before activity-core starts sending events
  that depend on the new selectors.
- The mapping is non-secret and may be stored in a ConfigMap or environment
  variable. `OPS_HUB_KEY` must remain Secret-only.

## Minimum Valid Mapping

For the first live smoke, an aggregate-only mapping is enough:

```json
{
  "version": "ops-hub.activity-core.widget-mapping.v1",
  "hub": {
    "slug": "ops-hub",
    "id": "<ops-hub-uuid>"
  },
  "policyScope": "ops-evidence",
  "defaultViewContext": "ops-inventory-probe",
  "events": {
    "ops-service-observed": {
      "family": "services",
      "aggregateWidgetRef": "ops:service:aggregate"
    },
    "ops-endpoint-verified": {
      "family": "endpoints",
      "aggregateWidgetRef": "ops:endpoint:aggregate"
    },
    "ops-access-path-checked": {
      "family": "accessPaths",
      "aggregateWidgetRef": "ops:access-path:aggregate"
    },
    "ops-backup-verified": {
      "family": "backups",
      "aggregateWidgetRef": "ops:backup:aggregate"
    },
    "ops-inventory-drift": {
      "family": "drift",
      "aggregateWidgetRef": "ops:drift:aggregate"
    }
  },
  "widgets": {
    "aggregate": {
      "ops:service:aggregate": { "widgetId": "<uuid>" },
      "ops:endpoint:aggregate": { "widgetId": "<uuid>" },
      "ops:access-path:aggregate": { "widgetId": "<uuid>" },
      "ops:backup:aggregate": { "widgetId": "<uuid>" },
      "ops:drift:aggregate": { "widgetId": "<uuid>" }
    }
  }
}
```
