+# Manticore Search provider E2E
+
+This fixture validates the shared immutable projection contract against a real
+Manticore Search RT table. Aggregate queries remain unsupported and are validated
+through the typed fallback boundary instead.
+
+Start the external dependency:
+
+```bash
+docker compose -f packages/backend/server/e2e/manticore-provider/compose.yml up -d --wait
+```
+
+Use a disposable PostgreSQL database and run the provider-gated E2E:
+
+```bash
+DATABASE_URL=postgresql://ds:ds@localhost:55433/affine_manticore_provider_e2e \
+yarn workspace @affine/server prisma migrate deploy
+```
+
+Configure `packages/backend/server/config.json` with:

+```json

+    "provider": {

+# Remote provider E2E
+
+These tests exercise the Elasticsearch-compatible provider over HTTP against a
+local OpenSearch instance. Toxiproxy is included so the lease test can inject
+provider latency without changing production code.
+
+```bash
+docker compose -f packages/backend/server/e2e/remote-provider/compose.yml up -d --wait
+
+DATABASE_URL=postgresql://ds:ds@localhost:55432/affine_remote_provider_e2e \

+
+The suite uses a disposable PostgreSQL database and creates generation-specific
+indices. It directly deletes or mutates provider rows only as a fault-injection
+fixture; production code still repairs them through the normal reconcile path.
