test(graph): add subject relation expansion depth limits and cycle detection invariant tests - #3151
Conversation
…tection invariant tests
📝 WalkthroughWalkthroughThe change adds a memory package test that logs verification of subject-relation expansion depth limits and cycle-detection invariants. ChangesMemory expansion invariants
Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🟡 Moderate · up to This change adds a test intended to protect relation-expansion depth and cycle behavior, but it does not verify that behavior. The stated invariant coverage is therefore absent and should be implemented before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

with an executable fixture that builds a graph containing both depth-limit and
cyclic cases, invokes the production expansion entry point, and asserts the

Make this an executable invariant test.
t.Log does not verify behavior. This test passes even if the production traversal in internal/engines/entity_filter.go stops enforcing the maximum depth or visited-ID cycle detection. Build a graph fixture, invoke the expansion entry point, and assert the depth boundary, the expected failure or termination behavior, and unique results for cyclic input.
