- Create handler.go with in-memory user store, request routing (/health, /users GET/POST, 404), and response types - Update User struct with Email field - Add dual-mode main(): standalone (no DATABASE_URL) vs postgres - Generate go.sum via go mod tidy - All 9 unit tests pass, go vet clean Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add http-response record type to WIT interface - Add 4 HTTP-level exported functions: test-http-get-users, test-http-post-user, test-http-post-invalid-json, test-http-db-unavailable - Implement Postgres DataRow parser and JSON formatter in guest - Guest simulates full HTTP handler flow: DB connect → query → JSON response Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add 4 HTTP-level integration tests using dynamic Val API: - GET /users → 200 with 5 seed users as JSON - POST /users → 201 with inserted user as JSON - POST with malformed JSON → 400 with error - DB unavailable → 503 with service unavailable error - All 10 integration tests pass (6 existing + 4 new) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Build from directory instead of single main.go file - Fix server readiness check to match actual log output Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

handler.go): In-memory HTTP handler with routing (/health,/usersGET/POST, 404),X-App-Nameheader, JSON error responses, and field validation. Enables unit testing without Postgres.main.go: Dual-mode — standalone (in-memory) whenDATABASE_URLis not set, pgx-based when it is.
