Native SONA engine returns Rust debug format instead of JSON

[scottkmcmillan]

I am vibe coding and claude-code declared and is currently working around it:

The native SONA engine returns Rust debug format instead of JSON:

CoordinatorStats { trajectories_buffered: 0, ... }

This is a bug in ruvector package v0.1.35 - the native binding's getStats() is using Rust's Debug trait instead of serializing to JSON.

Fix Applied

Changed get_stats() in both NAPI binding files from Debug format to proper JSON serialization:

Files modified:

• crates/sona/src/napi.rs (line 134-136)
• crates/sona/src/napi_simple.rs (line 200-202)

Before:

pub fn get_stats(&self) -> String {
    format!("{:?}", self.inner.stats())
}

After:

pub fn get_stats(&self) -> String {
    serde_json::to_string(&self.inner.stats())
        .unwrap_or_else(|_| "{}".to_string())
}

The CoordinatorStats struct already has #[derive(serde::Serialize)] when the serde-support feature is enabled (which NAPI enables by default).

This fix is pending the next native binary rebuild.
