About Radar RS Analyst

Radar RS Analyst is a native Rust Level II radar viewer focused on fast, high-fidelity CPU rendering. It loads public NEXRAD Level II data, shows a lightweight map-style radar canvas, overlays live NWS/SPC hazards, and keeps the native super-resolution pixel pattern visible for analyst workflows. This is early analyst software. The priority is a small, fast desktop app that preserves radar detail and keeps interaction fluid while the feature surface grows.

What's new in 0.2.2

Radar RS Analyst v0.2.2
Supersedes v0.2.1 with the accepted history/live/portability/velocity work plus the extra velocity-dealias spoke guardrails from review.
Highlights:
- Frame history with selectable 3/5/7/10/15/20/25/30 frame limits.
- Timeline scrubber, previous/next controls, and play/pause looping.
- Explicit Load Loop history backfill so normal live loading stays focused on current data.
- Level II live backfill and live partial handling with stale/partial/complete labels.
- Low-level live chunk display is gated by the Chunks option; default waits for a complete low-level tilt.
- Same-site live refresh preserves map view and product selection, including velocity.
- Multi-radar overlays remain available while the primary radar keeps priority.
- RadarScope/analyst-style stepped palette parsing and additional REF/VEL color presets.
- Plain VEL can use the dealiased continuity grid by default via Unfold VEL.
- Velocity dealias spoke guardrails: radial unfold cap reduced, stale slope propagation after gaps blocked, and isolated spoke cleanup retained.
- Portable cache/config paths; no Drew/source-tree runtime path dependency found in source or release EXE audit.
- Profiling examples for single and multi-radar decode/render/memory checks.
Verification:
- cargo test -p render2d velocity_dealias -- --nocapture
- cargo clippy --all-targets --all-features -- -D warnings
- cargo test -p render2d -p app_ui -p color_tables -p data_source
- cargo build --release -p app_ui with path remapping
- Source hardcoded-path audit passed.
- Release EXE binary string audit passed for Drew/Codex/Downloads/source-tree paths.
Known caveat:
The velocity dealiaser is still a lightweight local implementation, not a full GR2A/RadarScope-grade dealiaser. It now has additional radial-spoke guardrails, but complex velocity regions can still differ from commercial tools.
