πŸš€ Release Summary – v0.1.1

✨ Core Features

  • Event Injection Engine

    • Declarative events in YAML (server down/up, network spikes).
    • Strong validation via Pydantic (ID uniqueness, time bounds, type compatibility).
    • Runtime scheduler applies events deterministically in SimPy.
    • First phase of spike handling: deterministic latency offsets during event windows.
  • Server Runtime Improvements

    • Refined _handle_request: clearer separation of CPU blocking, I/O waiting, and RAM residency.
    • Added safeguard and comments for edge-case I/O handling (ensures robustness).

πŸ“– Documentation & README

  • Refreshed README.md:

    • Highlighted scenario-driven philosophy (Design Before You Code).
    • Added badges (PyPI, Python version, license, codecov, lint/type/tests, SimPy).
    • Embedded example outputs (dashboard + per-server metrics).
    • Clear Current Limitations section + link to ROADMAP.

πŸ› οΈ CI & Tooling

  • CI pipeline updated: now runs with coverage reporting (Codecov badge).
  • Workflow polish in ci-main.yml for consistency.

πŸ“¦ Examples

New examples with event injection both for a single server and two servers + load balancer
