+## Surface
+
+Serves the BI-P068 operation paths under `/api/0pt/analytics`:
+
+- `GET /health`
+- `GET /datasets`, `GET /datasets/{id}`
+- `GET /metrics`, `GET /metrics/{id}`, `GET /metrics/{id}/explain`
+- `POST /metrics/{id}/query`
+- `POST /query`, `POST /query/estimate`, `POST /query/explain`
+- `GET /query/{id}` (404: executions are not persisted yet)
+- `GET /dashboards`, `GET /reports` (empty until the BI metadata lane writes them)
+- `GET /search`
+
+Identity: the caller's Keycloak token is verified against the portal realm
+JWKS; `tenant_id` is taken from the token and cross-checked against
+`X-Tenant-Id`. An `X-Internal-Token` path exists only for the ingestion worker.
+
+## Ingest
+
+`ingest_aud0.py` maps AUD0 audit events to `opt_analytics_event`
+(`dataset_id=aud0.events`, `metric=event_count`, dimensions event_type/app_id/
+capability_id/risk_level). It is idempotent per `event_id`.
+
+```bash
+AUD0_TOKEN=... AUD0_TENANT_ID=... CLICKHOUSE_URL=http://opt-analytics-clickhouse:8123 \
+  python ingest_aud0.py --limit 50000

+This is the missing read plane between API0's `/analytics/*` contract and the

+model:
+
+  * datasets/metrics are the distinct ids actually present in
+    `opt_analytics_event` / `opt_metric_daily` / `opt_dataset_projection`;
+  * query/estimate/explain are computed against the tenant-forced ClickHouse

+token plus `X-Tenant-Id`. This service verifies the same token against the
+portal realm's JWKS and cross-checks `tenant_id` against `X-Tenant-Id`. A
+service-to-service `X-Internal-Token` is also accepted for the ingestion
+worker, but never for a request that reads tenant data without an explicit,
+already-verified `X-Tenant-Id`.

+One audit event becomes one analytics event with metric `event_count` and

+nothing.
