effect: "API response time increased from 200ms to 2000ms"
candidates:
  - "recent deployment"
  - "database load increase"
  - "memory leak"
context:
  timing: "started 2024-01-15 14:30"
  affected: "/api/users endpoint"

causes:
  - cause: "N+1 query introduced in recent deployment"
    strength: 0.85
    mechanism: "New eager loading removed; each user now triggers 3 additional queries"
    evidence:
      - "Deployment at 14:25, issue started 14:30"
      - "Query count per request increased from 2 to 50+"
      - "Database CPU correlates with API latency"
    type: "direct"
  - cause: "Database connection pool saturation"
    strength: 0.40
    mechanism: "Increased queries exhaust connection pool, causing wait times"
    evidence:
      - "Pool utilization at 95%"
      - "Connection wait time increased"
    type: "contributing"
mechanism: "The deployment removed eager loading, multiplying queries per request (2 to 50+); the database overloads and responses slow from 200ms to 2000ms"
strengths:
  n_plus_1_query: 0.85
  connection_pool: 0.40
  memory_leak: 0.05

alternatives_ruled_out:
  - cause: "memory leak"
    reason: "Memory usage stable, no growth pattern"
  - cause: "external service latency"

effect: "UserService#create test failing with 'Email already taken'"
candidates:
  - "test data pollution"
  - "code change"
  - "database state"

causes:
  - cause: "Missing database cleanup between tests"
    strength: 0.90
    mechanism: "Test creates user, doesn't clean up, subsequent test finds duplicate"
    evidence:
      - "Test passes in isolation"
      - "Test fails when run after create_user_test"
      - "No database_cleaner configuration"
    type: "direct"
mechanism: "A user created by an earlier test is never cleaned up, so a later create of the same email fails the uniqueness validation"
strengths:
  test_pollution: 0.90
  code_change: 0.05
  fixture_issue: 0.05
causal_chain:
  - step: "First test runs"
    from: "empty database"

  - step: "Second test attempts create"
    from: "user exists"
    to: "uniqueness validation fails"
alternatives_ruled_out:
  - cause: "code change"
    reason: "No recent changes to UserService"
  - cause: "fixture issue"
