## [Unreleased]

## [0.1.0] - 2026-02-18

### Added

- **Overview Dashboard** — driver health card, storage summary (StorageClass / PV / PVC counts), protocol distribution with PercentageBar, non-Bound PVC alert table, and live Prometheus metric snapshot
- **Storage Classes page** — table with Protocol, Pool, Server, Reclaim Policy, Expansion, and PV count columns; slide-in detail panel with protocol-specific prerequisite notes (NFS, NVMe-oF, iSCSI)
- **Volumes page** — PersistentVolume table with capacity, access modes, reclaim policy, phase status badge, and bound claim; slide-in detail panel with full CSI volume attributes
- **Snapshots page** — VolumeSnapshot table scoped to tns-csi VolumeSnapshotClasses; graceful degradation when snapshot CRD is not installed
- **Metrics page** — Prometheus WebSocket health indicator, per-volume I/O (read/write IOPS and bandwidth), CSI operation latency cards from controller pod port 8080
- **Benchmark page** — interactive kbench runner with StorageClass selection, capacity/access-mode configuration, Job+PVC lifecycle management, live FIO log streaming, and IOPS/bandwidth/latency result cards
- **PVC Detail Injection** — TNS-CSI section automatically injected into Headlamp's PVC detail views showing protocol, server, pool, volume handle, and link to the bound PV
- **TnsCsiDataContext** — shared React context provider for all plugin pages; extracts `jsonData` from Headlamp KubeObject instances so StorageClass `parameters` (protocol, pool, server) are accessible
- **Prometheus text format parser** — zero-dependency parser for the Prometheus exposition format used by the tns-csi controller
- **kbench FIO log parser** — parses `yasker/kbench` FIO output into structured IOPS, bandwidth (MB/s), and latency (µs) results
- **ArtifactHub publishing** — `artifacthub-pkg.yml` and `artifacthub-repo.yml` registered at Artifact Hub; plugin available in Headlamp catalog

### Infrastructure

- GitHub repository setup with initial CI and release workflows
- 67 unit tests with Vitest + @testing-library/react
- TypeScript strict mode with zero `any` types
- ESLint + Prettier code quality tooling
