Research direction
Start with the README feature matrix and the decisions in #2930, then inspect xrspatial/polygonize.py, contour.py, rasterize.py, and polygon_clip.py. Run the listed deep sweep against polygonize.py and review each linked bug issue. Done requires resolved scope and dark-corner decisions, no CRITICAL or HIGH findings, and completed notebook coverage.

Description
1.0.0 readiness: Raster / Vector conversion
Area: Vector Functions: polygonize, contours, rasterize, clip_polygon
Source: xrspatial/{polygonize,contour,rasterize,polygon_clip}.py
Scope
- Public surface frozen against the README feature matrix
- Dark-corner decisions resolved (see #2930)
Sweep clearance, no CRITICAL or HIGH (accuracy and security first)
- Accuracy
/deep-sweep xrspatial/polygonize.py - Security
- Performance
- API consistency
Last swept: none yet
Examples
- Notebook example
- (optional) standalone script
Linked bug issues
- #2538 (Medium) polygonize: dask backend processes chunks serially, no parallelism
- #2677 (High) Dask 8-connectivity float polygonize diverges from numpy at large rtol
- #2788 (Low) contours() validates return_type too late, wasting compute on invalid values
- #2790 (Medium) contours() emits degenerate and duplicate lines for exact-level plateaus
- #2791 (Low) contours(): n_levels is not validated as a positive integer
- #2795 (Low) contours() emits RuntimeWarning on all-NaN input with auto level selection
