boundary-analyzer 0.3.4

SCOM-based microservice boundary analysis from Jaeger traces

Changelog

v1.0.0 (2026-06-11)

Features

• SCOM pipeline : computes Service-COhesion Metric from Jaeger traces (health filtering, endpoint extraction, DB table detection, endpoint-table mapping, threshold analysis, report generation)
• CLI tool : mba / boundary-analyzer commands (run, setup, dashboard, teastore)
• Auto-instrumentation : auto-detects Python microservices (FastAPI, Flask, Django), injects OpenTelemetry, collects traces via Jaeger, runs SCOM analysis
• TeaStore support : Docker Compose deployment with OTel Java agent, traffic generator, trace exporter, full SCOM pipeline
• Dashboard : interactive Dash web UI for SCOM results
• LLM analysis (optional) : AI-powered narrative report via OpenRouter (Qwen), disabled by default

Improvements

• Segment-based health matching (HEALTH_KEYWORDS) instead of fragile endswith — /health/all, /auth/health, /ready/isready, /metrics (via http.target) correctly filtered
• --skip-no-db-services flag to exclude stateless services (proxy, orchestrator, etc.) from SCOM ranking
• run_teastore() function extracted for programmatic access

Bug fixes

• MissingGreenlet in classroom-repository (added selectinload)
• datetime timezone-aware comparison in enrollment-service
• academic_year int→str conversion in enrollment-service
• Scope bug in cleaned_parts variable in CLI cleanup logic
• SQLAlchemy duplicate instrumentation (event listeners only, no SQLAlchemyInstrumentor/AsyncPGInstrumentor)
• [project.scripts] whitespace in pyproject.toml

Tests

• 74 tests total (58 existing + 16 TeaStore)
• TeaStore synthetic fixtures (persistence-service with 5 tables, auth-service without DB)
• 3 test classes : TeaStorePipelineTest, TeaStoreSkipNoDbTest, TeaStoreNoFilterTest

Infrastructure

• CI via GitHub Actions (.github/workflows/ci.yml) — Python 3.11 × 3.12
• mba CLI alias alongside boundary-analyzer
• Version bump to 0.2.0
