+# echo
+
+Echo v4 on the Go `net/http` server, default configuration.
+
+## Stack
+
+- **Language:** Go 1.26
+- **Framework:** Echo v4
+- **Build:** `golang:1.26-alpine` -> `alpine:3.23` runtime
+
+## Endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/pipeline` | GET | Returns `ok` (plain text) |
+| `/baseline11` | GET | Sums query parameter values |
+| `/baseline11` | POST | Sums query parameters + request body |
+| `/json/{count}?m=N` | GET | First `count` dataset items with `total = price * quantity * m` |
+| `/upload` | POST | Reads the body and returns the byte count |
+
+## Notes
+
+- Routing and path parameters through the Echo router, JSON through `c.JSON`
+- Compression through the Echo `Gzip` middleware
+- Banner and port log disabled, no other middleware installed
