GoSched v1.0.0 — Initial release

Production-ready real-time task scheduler for Go portfolios and backend systems.

Core

• Custom binary heap with O(log n) push/pop
• Discrete-event engine with async task intake and worker pool
• CLI: schedule, visualize, benchmark

APIs and observability

• HTTP REST — POST /api/v1/schedule, GET /health, GET /metrics
• gRPC — Schedule, Health (proto in api/proto/)
• Prometheus metrics — completed/missed tasks, wait time, CPU util, queue depth
• Gantt charts — ASCII console + PNG export

Extensibility

• Go plugins (.so on Linux/macOS) via --plugin
• Custom schedulers via scheduler.NewCustom

Quality

• Unit + integration tests, benchmarks, GitHub Actions CI
• Docs: architecture, algorithms, API, plugins
