<context>
This is a triage decision ticket. It must be resolved before dependent implementation tickets can proceed.

<question>
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`?
</question>

<options>
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.
</options>

<decision>
**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`:
```rust
#[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).

See implementation ticket 00aff0 for full details.
