**1 issue found** across 8 files Confidence score: **3/5** - There is a concrete rendering regression risk in `node-graph/libraries/rendering/src/render_ext.rs`: open paths with `aligned_strokes` disabled may omit `stroke-width`, causing SVG to fall back to width 1 instead of the intended 0.5 behavior. - Given the medium severity (5/10) and fairly strong confidence (7/10), this looks user-visible but scoped to stroke serialization logic rather than a broad system-wide failure. - Pay close attention to `node-graph/libraries/rendering/src/render_ext.rs` - verify open-path stroke defaults are emitted correctly when aligned strokes are disabled.

P2: The new default treats 0.5 as the SVG default for non-centered strokes even when aligned strokes are disabled. For open paths (where `aligned_strokes` is false), this omits `stroke-width` and SVG falls back to 1, rendering thicker strokes than requested (e.g., weight 0.5 becomes 1). Consider only using the 0.5 default when `aligned_strokes` is enabled. ```
