c1bc32d50a feat(02-02): implement ELK diagram renderer with SVG/JSON content negotiation 
- ElkDiagramRenderer: ELK layered layout (top-to-bottom) with JFreeSVG rendering
- Color-coded nodes: blue endpoints, green processors, red errors, purple EIPs, cyan cross-route
- Compound node support for CHOICE/SPLIT/TRY_CATCH swimlane groups
- DiagramRenderController: GET /api/v1/diagrams/{hash}/render with Accept header negotiation
- DiagramBeanConfig for Spring wiring
- 11 unit tests (layout, SVG structure, colors, compound nodes)
- 4 integration tests (SVG, JSON, 404, default format)
- Added xtext xbase lib dependency for ELK compatibility

f6ff279a60 feat(02-01): extend ingestion to populate Phase 2 columns with integration tests 
- Refactored flattenProcessors to flattenWithMetadata (FlatProcessor record with depth/parentIndex)
- INSERT now populates 12 new columns: exchange_bodies, exchange_headers, processor_depths,
  processor_parent_indexes, processor_error_messages, processor_error_stacktraces,
  processor_input_bodies, processor_output_bodies, processor_input_headers,
  processor_output_headers, processor_diagram_node_ids, diagram_content_hash
- Exchange bodies/headers concatenated from all processor snapshots + route-level snapshots
- Null ExchangeSnapshot handled gracefully (empty string defaults)
- Headers serialized to JSON via Jackson ObjectMapper
- IngestionSchemaIT verifies 3-level tree metadata, body concatenation, null snapshot handling
- DiagramRenderer/DiagramLayout stubs created to fix pre-existing compilation error (Rule 3)

8fe65f083c feat(01-02): implement ingestion REST controllers with backpressure 
- ExecutionController: POST /api/v1/data/executions (single or array)
- DiagramController: POST /api/v1/data/diagrams (single or array)
- MetricsController: POST /api/v1/data/metrics (array)
- All return 202 Accepted or 503 with Retry-After when buffer full
- Fix duplicate IngestionConfig bean (remove @Configuration, use @EnableConfigurationProperties)
- Fix BackpressureIT timing by using batch POST and 60s flush interval
- All 11 integration tests green

2d3fde3766 test(01-03): add integration tests for health, OpenAPI, protocol version, forward compat, and TTL 
- HealthControllerIT: health returns 200, no protocol header needed, TTL verified
- OpenApiIT: api-docs returns OpenAPI spec, swagger UI accessible
- ProtocolVersionIT: missing/wrong header returns 400, correct header passes, excluded paths work
- ForwardCompatIT: unknown JSON fields do not cause deserialization errors
- Fix testcontainers version to 2.0.3 (docker-java 3.7.0 for Docker Desktop 29.x compat)
- Fix ClickHouse schema: TTL with toDateTime() cast, non-nullable error columns for tokenbf_v1
