Unreleased

zook serve daemon: HTTP API with POST /deploy / POST /rollback (async jobs, bearer-token auth, fail-closed when unset), GET /stacks, GET /stacks/{name}, GET /jobs/{id}, and GET /healthz.
GitHub webhook receiver (POST /hooks/github) with HMAC-SHA256 signature verification; push events auto-deploy stacks configured via deploy_on.github (branch: exact match or tag: glob) in zook.yaml.
Per-stack deploy serialization in the daemon (one in-flight deploy per stack, 409 on conflict).

CLI: deploy, rollback, status, releases, list, logs, version.
Docker Compose runtime with health-gated deploys (up -d --wait).
Preflight that refuses to deploy stacks whose active services lack a healthcheck.
Automatic, health-gated rollback on failed deploys; halts for manual intervention when a rollback also fails.
Per-stack release state (.zook/state.json) and per-deploy logs.
Native/systemd runtime: deploy prebuilt binaries via release directories, a current symlink, and systemctl restart, with zook-managed health polling.
zook.yaml per-stack config: selects the runtime (docker default, or native) and sets overrides (health_timeout, rollback_on_fail).
HTTP/command health prober used by the native runtime.
HTTP artifact fetcher (.tar.gz or single binary) for native releases.
RUNTIME column in zook list and zook status.
Static site generator (site/gen, make site) that renders the handbook.
Homebrew distribution via GoReleaser: darwin/linux x amd64/arm64 archives, a GitHub release, and a cask pushed to oti-adjei/homebrew-tap.
CI workflow running gofmt, go vet, go test, and a build on push and PR.

Stack discovery follows symlinked stack directories, so a stack linked into the stacks root from an application repo appears in zook list and zook status, not just zook deploy.
