Daily Update — 2026-04-02

​

Main updates shipped

• Multi-provider LLM support — added OpenRouter, Gemini, and NVIDIA NIM providers with automatic detection via LLM_PROVIDER env var, alongside fixes to make chat nodes (general_node, chat_agent_node) fully provider-aware for OpenAI and Anthropic with provider-keyed caches and lazy imports.
• Pydantic config rollout — replaced ad-hoc config handling with a Pydantic-based strict config across the app, touching CLI, integrations, state, and tooling layers.
• Simulation engine overhaul — large rework of the synthetic test engine (+1470/-735) covering root-cause diagnosis nodes, the mock Grafana backend, and RDS Postgres scenario fixtures including new replication-lag and connection-exhaustion scenarios.
• Expanded RDS Postgres metric fixtures — split the 000-healthy CloudWatch metrics pack into per-metric JSON files (CPUUtilization, ReplicaLag, WriteIOPS, etc.) and updated the scenario loader and fixture generator accordingly.
• Grafana local demo moved to wizard CLI — Grafana stack seeding and live-demo entrypoints now live under app/cli/wizard/, Make targets updated, and the obsolete bundled local RCA demo path removed.
• CLI improvements — better error message for unknown test IDs (hints opensre tests list), simplified JSON output handling in args.py, and a readability refactor in investigate.py with lint fixes.
• Tooling hygiene — added .editorconfig (4-space Python, 100-char line length, matching ruff.toml), added .ruff_cache/ to .gitignore, removed unused mypy.ini kubernetes stubs, and disabled PostHog analytics firing in CI environments.
• Release workflow & CI — added release.yml GitHub Actions workflow and improved the wizard onboarding flow to avoid re-prompting for provider selection.
