Verified every value in this guide against plane-enterprise chart 3.5.7 (appVersion v3.1.4). Fixes for things that would fail if followed: - Chart version was pinned to 1.6.4 in four places (latest is 3.5.7). Now a single CHART_VERSION variable, with `helm repo add`/`helm pull` as the primary path and Artifact Hub as the version source. - Every service image placeholder was malformed (`image: /web-commercial`, and `image: /email-commercial:` with a trailing colon). The chart renders `<image>:<planeVersion>`, so these produced invalid references. Fixed to full internal-registry paths, with a warning that `services.*.image` takes a repo without a tag and that iframely is the sole exception. - busybox was missing from the transfer list. The chart runs BusyBox init containers for silo (wait-for-rabbitmq, unconditional), silo/live (prepare-ca-bundle, when an S3 CA secret is set) and the MinIO client job. Added an "Init container images" section covering the three init_image keys and recommending a pinned tag over the implicit busybox:latest. - dockerRegistry was never mentioned, so an authenticated internal registry left every pod in ImagePullBackOff. Added. - license.licenseDomain was never set, so the guide produced an instance on plane.example.com. Added. - The TLS example drove cert-manager at Let's Encrypt (and offered Cloudflare and DigitalOcean DNS issuers), none of which are reachable from an air gap. Rewritten around ssl.tls_secret_name from an internal CA, with ssl.externalTermination for upstream termination. - The chart's shipped placeholder secrets were copied into the page verbatim. Replaced with a "Rotate the default secrets" section covering secret_key, live_server_secret_key, the silo_envs keys, pi_envs.internal_secret and the bundled datastore credentials, with generate commands. - Valkey was listed as both 7.2.5-alpine and 7.2.11-alpine on the same page; the chart says 7.2.11-alpine. - OpenSearch was called out in two callouts but had no config block. Additions: - Staging-host vs airgapped-host labelling on every command, and an explicit step for transferring the chart archive, licence file and CA certificate. - env.storageClass guidance (airgapped clusters often have no default class, and PVCs otherwise sit Pending). - ingress.controller, which silently renders no ingress at all when the class name is not exactly nginx/openshift/traefik*. - pullPolicy: IfNotPresent rationale for airgapped registries. - Optional Plane AI (services.pi, services.runner) and hardened-cluster (securityContext) sections. - Real log commands in Verify; the page previously said "check the logs using the commands above" with no such commands. - An Upgrade section, noting licences are issued per Plane version. - A Troubleshooting section for ImagePullBackOff, Pending PVCs, migrator failures and the missing-ingress case. Structure: airgapped-specific frontmatter description (it was a byte-for-byte copy of kubernetes.md), title and H1 aligned, consistent "airgapped" spelling, a/b/c/d sub-steps promoted to headings, and relative links with descriptive text.

In `@docs/self-hosting/methods/airgapped-edition-kubernetes.md`:
- Around line 288-289: Update the airgapped Kubernetes pull-policy guidance to
include the enabled pi and runner services alongside the existing service list,
or explicitly state that every enabled service must use IfNotPresent. Ensure the
guidance covers services.pi and services.runner so cached images can restart
without registry access.
- Line 36: Reconcile the cert-manager prerequisite between this guide and
airgapped-requirements.md: either make cert-manager consistently required, or
explicitly document a pre-issued internal-CA Secret as the supported exception
when certificates are not issued in-cluster. Keep the air-gapped constraints for
internal CA configuration and unavailable public issuers consistent across both
guides.
- Around line 159-163: Update the Helm chart values guidance around
custom-values.yaml to prohibit committing live credentials. Require Kubernetes
Secret or external-secret references for registry, datastore, connector, and
GitHub credentials, and clearly state that inline credential fields are
placeholders only and must not contain real secrets.

- Pull policy: the IfNotPresent list omitted services.pi and services.runner. The chart has no global pull-policy value and both default to Always, so a cached Plane AI image could still fail to restart while the registry was unreachable. Now spells out every enabled service, and notes the bundled datastores already default to IfNotPresent. - cert-manager: this guide scoped it to in-cluster issuance while airgapped-requirements.md listed it as a required component. Both pages now state the two supported paths — a pre-issued certificate loaded as a TLS Secret and referenced with ssl.tls_secret_name, or cert-manager with an internal CA issuer — and that public ACME and DNS-01 issuers are unreachable either way. - Credentials: the guide told readers to keep custom-values.yaml under version control while showing inline credential fields. It now marks those fields as placeholders and directs real values to Kubernetes Secrets via dockerRegistry.existingSecret and the external_secrets.*_existingSecret keys, managed by Vault, ESO, or sealed-secrets. Connector client secrets and the GitHub App private key are called out at the integrations section too. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Summary
Rewrites
self-hosting/methods/airgapped-edition-kubernetes.md. Every value in the page was checked against theplane-enterprise3.5.7 chart (appVersionv3.1.4), pulled and read locally.The page had several defects that would break an install for anyone following it end to end.
Fixes

Now a singleCHART_VERSIONvariable, withhelm repo add/helm pullas the primary path.image: /web-commercial, andimage: /email-commercial:with a trailing colon.
