+Feature: Ingestion pipeline — PDF → chunks → embeddings → OpenSearch
+
+  Background:
+    * url baseUrl
+
+  Scenario: Upload PDF, analyze with chunking, ingest into OpenSearch, verify
+
+    # Step 1: Check ingestion is available
+    Given path '/api/ingestion/status'
+    When method GET
+    Then status 200
+    And match response.available == true
+
+    # Step 2: Upload a PDF
+    Given path '/api/documents/upload'
+    And multipart file file = { read: 'classpath:common/data/generated/medium.pdf', filename: 'medium.pdf', contentType: 'application/pdf' }
+    When method POST
+    Then status 200
+    * def docId = response.id
+
+    # Step 3: Create analysis with chunking
+    Given path '/api/analyses'
+    And request { documentId: '#(docId)', pipelineOptions: { doOcr: true, tableMode: 'fast' }, chunkingOptions: { chunkerType: 'hybrid', maxTokens: 256 } }
+    When method POST
+    Then status 200
+    * def jobId = response.id
+
+    # Step 4: Poll until completed
+    Given path '/api/analyses', jobId
+    And retry until response.status == 'COMPLETED' || response.status == 'FAILED'
+    When method GET
+    Then status 200
+    And match response.status == 'COMPLETED'
+    And match response.chunksJson == '#string'
+
+    # Step 5: Trigger ingestion
+    Given path '/api/ingestion', jobId
+    When method POST
+    Then status 200

+    And match response.chunksIndexed == '#number'
+    And assert response.chunksIndexed > 0
+    And match response.embeddingDimension == '#number'
+    And assert response.embeddingDimension > 0
+
+    # Step 6: Cleanup — delete ingested data
+    Given path '/api/ingestion', docId
+    When method DELETE
+    Then status 204
+
+    # Step 7: Cleanup — delete analysis and document
+    Given path '/api/analyses', jobId
+    When method DELETE
+    Then status 204
+
+    Given path '/api/documents', docId
+    When method DELETE
+    Then status 204
