Needle Thread

A quieter surface area that rewards chaining: Node service on `:8080` with `GET /download?file=` path traversal into `/opt/app/public`, Redis listening on `:6379` with `protected-mode no` and no auth, and a stray backup config at `/opt/app/backup/config.yml.bak` (Redis creds and weak secrets). Expect slow-burn enumeration, file-read-to-secret harvesting, and Redis pivots before flag captures.
