[TRIAGE] workers-rs compatibility with native Rust test binaries (may need separate native feature flag)	completed	task	critical	2026-03-10T23:32:09Z	2026-03-10T23:32:09Z

This is a triage decision ticket. It must be resolved before dependent implementation tickets can proceed. workers-rs compatibility with native Rust test binaries: the workers-rs crate targets the Cloudflare Workers runtime, not native Linux/macOS. Can the API code be compiled as a native binary for `cargo test`? 1. **Conditional compilation** — use `#[cfg(target_env = "worker")]` to switch between workers-rs entry point and a plain Axum server. The native build is used for testing. 2. **Feature flags** — add a `native` feature that enables the Axum server path. `cargo test` uses `--features native`. 3. **Separate test binary** — integration tests spawn a separately compiled native test server binary. **Option 1 variant: `cfg(target_arch = "wasm32")` — no feature flag needed.**

Note: target_env = "worker" is incorrect. The right discriminant is target_arch = "wasm32".

The cfg(target_arch) split is cleaner than a feature flag because it is tied to the actual build target, not an opt-in flag that could be forgotten:

• [target.'cfg(target_arch = "wasm32")'.dependencies] → workers-rs (pulled in only for WASM)
• [target.'cfg(not(target_arch = "wasm32"))'.dependencies] → tokio, axum, rusqlite (native only)

In main.rs:

#[cfg(target_arch = "wasm32")]
#[worker::event(fetch)]
pub async fn main(...) { /* workers-rs entry point */ }

#[cfg(not(target_arch = "wasm32"))]
#[tokio::main]
async fn main() { /* native Axum server on :8080 */ }

cargo test (native host) automatically compiles the native path. No special flags. No feature flag pollution. Resolved as part of TRIAGE e8a330 (DB strategy decision).
