Graph Query and Search API

Module

Graph

Status

VERIFIED

Description

Graph API with query, search, and path services for traversing and querying dependency graphs.

Implementation Details

  • Query service: src/Graph/StellaOps.Graph.Api/Services/IGraphQueryService.cs, InMemoryGraphQueryService.cs -- graph node/edge query with filtering
  • Search service: src/Graph/StellaOps.Graph.Api/Services/IGraphSearchService.cs, InMemoryGraphSearchService.cs -- full-text search across graph entities
  • Path service: src/Graph/StellaOps.Graph.Api/Services/IGraphPathService.cs, InMemoryGraphPathService.cs -- shortest-path and reachability path queries
  • Repository: src/Graph/StellaOps.Graph.Api/Services/InMemoryGraphRepository.cs -- in-memory graph data store
  • Search contracts: src/Graph/StellaOps.Graph.Api/Contracts/SearchContracts.cs -- search request/response DTOs
  • Lineage contracts: src/Graph/StellaOps.Graph.Api/Contracts/LineageContracts.cs -- lineage query contracts
  • Reachability contracts: src/Graph/StellaOps.Graph.Api/Contracts/ReachabilityContracts.cs -- reachability query contracts
  • Rate limiting: src/Graph/StellaOps.Graph.Api/Services/RateLimiterService.cs -- query rate limiting
  • Tests: src/Graph/__Tests/StellaOps.Graph.Api.Tests/QueryServiceTests.cs, SearchServiceTests.cs, PathServiceTests.cs, RateLimiterServiceTests.cs
  • Source: Feature matrix scan

E2E Test Plan

  • Verify query API returns nodes and edges matching filter criteria
  • Test full-text search returns ranked results across graph entities
  • Verify path queries find shortest paths between nodes
  • Test rate limiting prevents query abuse
  • Verify search contracts handle empty results and pagination

Verification

  • Run ID: run-001
  • Date: 2026-02-09T16:00:00Z
  • Tier: 1 (Build + Test)
  • Result: PASS
  • Evidence: Query/search/path/rate-limiter tests all pass. All source files verified (15/15).
