v0.3.0 — TUI Dashboard & Observability

TUI Dashboard & Observability

Focus: real-time operator visibility via fullscreen terminal dashboard.

Added

• Fullscreen ratatui TUI dashboard (default; disable with --no-tui)
  • Phase indicator, progress bar, coverage map, speed chart
  • Network, queue, storage, DB, and RPC panels
  • DOS-style splash screen with animated connection status
  • Real-time log viewer with level coloring
• TUI log capture (circular buffer, suppresses stdout in TUI mode)
• Per-shard compaction during fast-sync (shards compact as they fill)
• P2P stats tracking: discovery count, genesis mismatches, sessions
• RPC stats tracking: total requests, per-method counters, errors
• Coverage tracker with bucket-based braille visualization
• Peak speed tracking and follow-mode staleness detection
• Stale-peer banning with 120s cooldown and async re-probe
• Peer feeder rotation for fairness
• Stall detection with peer health dump (30s threshold)
• Sealed shard cache for fast startup on slow storage
• db compact subcommand with progress bars, JSON logging, per-shard timing
• db rebuild-cache subcommand to rebuild sealed shard cache
• --defer-compaction flag to skip inline compaction during fast-sync
• SHiNode branding: renamed binary to shinode, website (shinode.rs)
• MIT/Apache-2.0 dual licensing
• Workspace Cargo.toml
• Pre-built binaries (Linux x86_64, macOS ARM, macOS x86_64)

Changed

• Binary renamed from stateless-history-node to shinode
• Storage open performance: 8MB read buffers, in-memory WAL reads, cached disk stats
• ShardMeta now tracks total_logs, total_transactions, total_receipts, disk_bytes_*
• StorageAggregateStats for cheap cross-shard rollup (no disk I/O)
• Read-only segment readers (prevents follow-mode file-lock crash)

Fixed

• Follow-mode stale-peer spin-loop
• Follow-mode head desync
• Follow-mode log dedup
