The typed fetch client accepts calls to POST-only routes without a method. These calls pass typechecking but send GET, so the POST handler never runs.

For a route that only exports POST, both calls previously compiled:

await fetch('/api/rebuild', {});
await fetch<'/api/rebuild', 'POST'>('/api/rebuild', {});

Both send GET. The POST type argument only affects TypeScript; it does not set the request method.

Cause

The fetch types made method optional for every request and allowed calls without options even when the route had no GET handler.

Fix

Require an explicit method for non-GET requests. The calls above now produce a missing-method error, while the correct call continues to work:

await fetch('/api/rebuild', { method: 'POST' });

Also clarify the requirement in the typed fetch documentation.
