Postgres-backed External Node Classifier for Puppet, replacing Cobbler. - encapi HTTP server (chi + pgx): read/write API + two ENC document shapes (reshaped for the exec terminus; cobbler-wire for enc_direct_facts.rb) - encapi-cli: classify/node/role/status CRUD + import-cobbler seeder - pkg/client Go SDK; unit tests across all packages (DB via testcontainers) - Dockerfile (distroless), Makefile, nfpm RPM (encapi-cli + encapi-enc wrapper), Woodpecker CI, docs/cutover.md
