services.rs:
- Pod status with unicode icons, grouped by namespace
- VSO sync status (VaultStaticSecret/VaultDynamicSecret via kube-rs DynamicObject)
- Log streaming via kube-rs log_stream + futures::AsyncBufReadExt
- Pod get in YAML/JSON format
- Rollout restart with namespace/service filtering

checks.rs:
- 11 health check functions (gitea, postgres, valkey, openbao, seaweedfs, kratos, hydra, people, livekit)
- AWS4-HMAC-SHA256 S3 auth header generation using sha2 + hmac
- Concurrent execution via tokio JoinSet
- mkcert root CA trust for local TLS

secrets.rs:
- Stub with cmd_seed/cmd_verify (requires live cluster for full impl)

users.rs:
- All 10 Kratos identity operations via reqwest + kubectl port-forward
- Welcome email via lettre SMTP through port-forwarded postfix
- Employee onboarding with auto-assigned ID, HR metadata
- Offboarding with Kratos + Hydra session revocation

gitea.rs:
- Bootstrap without Lima VM: admin password, org creation, OIDC auth source
- Gitea API via kubectl exec curl

images.rs:
- BuildEnv detection, buildctl build + push via port-forward
- Per-service builders for all 17 build targets
- Deploy rollout, node image pull, uv Dockerfile patching
- Mirror scaffolding (containerd operations marked TODO)

cluster.rs:
- Pure K8s cmd_up: cert-manager, linkerd, rcgen TLS certs, core service wait
- No Lima VM operations

manifests.rs:
- Full cmd_apply: kustomize build, two-pass convergence, ConfigMap restart detection
- Pre-apply cleanup, webhook wait, mkcert CA, tuwunel OAuth2 redirect patch
