136-137: Add explanatory comment for the duck-typing detection logic.

The detection logic is correct, but relies on duck-typing which is fragile if underlying frameworks change. As noted in a previous review, add a comment explaining this coupling:

+        // Detect Hono adapter by checking for properties on the response context.
+        // This is coupled with `@kiyasov/platform-hono`.
+        // See: https://github.com/kiyasov/platform-hono/pull/10
         const isHono = 'finalized' in res && typeof (res as HonoContext).newResponse === 'function'
+        // Fastify also has `raw` on request, so exclude Hono first
         const isFastify = 'raw' in req && !isHono

24-29: Well-defined minimal interface.

The interface correctly models only the relevant Hono context surface area. The optional res property accurately reflects that it's assigned by the interceptor rather than being initially present.

Consider adding a brief JSDoc comment explaining this interface's purpose and its coupling to @kiyasov/platform-hono:

+/**
+ * Minimal interface for Hono-like request/response context.
+ * Coupled with @kiyasov/platform-hono behavior.
+ * @see https://github.com/kiyasov/platform-hono/pull/10
+ */
 interface HonoContext {

Add one Hono assertion for dynamic/overridden status propagation.

This test covers happy-path/error-path well, but it doesn’t yet pin the Hono-specific response conversion for custom statuses. A regression in toFetchResponse/newResponse could still pass here. Add a request where ping_handler returns status: 203 (or a sendResponseInterceptor override) and assert the HTTP status.

Suggested test addition

       try {
         const pingRes = await supertest(httpServer)
           .post('/ping?param=value&param2[]=value2&param2[]=value3')
           .set('x-custom', 'value')
           .send({ hello: 'world' })

         expect(pingRes.statusCode).toEqual(200)
         expect(pingRes.body).toEqual('pong')
         expect(pingRes.headers).toEqual(expect.objectContaining({ 'x-ping': 'pong' }))
+        
+        ping_handler.mockResolvedValueOnce({ body: 'pong', headers: { 'x-ping': 'pong' }, status: 203 } as any)
+        const ping203Res = await supertest(httpServer)
+          .post('/ping?param=value')
+          .send({ hello: 'world' })
+        expect(ping203Res.statusCode).toEqual(203)

In `@packages/nest/src/implement.test.ts` around lines 700 - 736, Add an assertion
that verifies Hono-specific status propagation by creating a request where
ping_handler returns a non-default status (e.g., status: 203) or by using the
sendResponseInterceptor to override the response status, then send that request
in the same test block and assert the HTTP status equals 203; locate the
existing pingRes/ping_handler usage in the test (references: ping_handler and
pong_handler) and add a new supertest call and
expect(...statusCode).toEqual(203) to ensure toFetchResponse/newResponse
correctly preserves custom statuses.
