Publish CDN gateway beta chart 1.8.63-16069

[allyblockcast]

Summary

• Publish beta chart artifacts for cdn-gateway and cdn-gateway-orc8r-prereqs version 1.8.63-16069.96f1bf07.
• Rebase the 16069 entries on top of the current gh-pages index, which already contains 1.8.63-16072.899a3d9d.
• Gateway package was rebuilt from a sanitized public chart copy so public artifacts do not expose literal secret defaults, internal ticket IDs, private IP examples, runbook text, SOPS payloads, or private keys.

Exposure review

• Linked cleanup/review issue: BLO-13243.
• Public package scan: tar -xOf beta/cdn-gateway-1.8.63-16069.96f1bf07.tgz | rg 'password: "?blockcast|BLO-[0-9]+|192\.168\.|10\.42\.42\.2|runbook|SOPS|PRIVATE KEY' returned no matches.
• Prereqs package scan with the same pattern returned no matches.

Verification

• helm lint cdn/gateway/helm/cdn-gateway-orc8r passed in Blockcast/magma.
• helm lint cdn/gateway/helm/cdn-gateway-orc8r-prereqs passed in Blockcast/magma.
• helm template blockcastd beta/cdn-gateway-1.8.63-16069.96f1bf07.tgz --namespace blockcastd-test passed.
• helm template blockcastd-prereqs beta/cdn-gateway-orc8r-prereqs-1.8.63-16069.96f1bf07.tgz --namespace blockcastd-test passed.

@ally Please review the beta chart publication for BLO-13230. Focus: the PR adds the missing 1.8.63-16069.96f1bf07 beta artifacts on top of current gh-pages, the gateway package is intentionally sanitized for public exposure, and the index digests match the package SHA256 values. Verification commands and exposure scans are in the PR body.

Scope note

This diff is a chart-repo publish action (beta/index.yaml + two new .tgz artifacts on gh-pages), not application source — the underlying template source was already lint/tested in Blockcast/magma per the PR description. I focused the review on the publish action itself rather than re-reviewing template logic that lives upstream.

Independent verification performed

• Downloaded both .tgz artifacts at this head and re-ran (and broadened) the secret-exposure scan claimed in the PR description — no matches for internal ticket IDs, private IPs, SOPS payloads, private key material, or literal cloud/chat tokens (ghp_/xox*-/AKIA*).
• Broadened grep also caught tmClientKeyPassword: "changeit", authKeySecret: "cast-tailscale", COOKIES_SECRET default "cast-yt-cookies", and encPassword: "localdev-test-password" — all confirmed benign on inspection: changeit is the standard Java keystore default, the other two are Kubernetes Secret object names (actual key material is pulled via secretKeyRef, not embedded), and the encPassword default is explicitly gated/commented as a localdev-only bypass.
• Recomputed sha256 of both packages and confirmed they match the digest: fields written into beta/index.yaml exactly — no artifact/index drift.
• Confirmed no pre-existing 1.8.63-16069.* entry on gh-pages today, so this is a net-new publish, not a silent overwrite of an existing version.

Suggestions (1)

• [native-codex] beta/index.yaml — The newly-added 1.8.63-16069.* entries have a lower embedded build number than the 1.8.63-16072.* entries already present in the index (per the PR description, this is an intentional out-of-order backfill). Helm's semver precedence still resolves "latest" correctly since prerelease identifiers are compared numerically, so this isn't a functional bug — just worth a one-line callout in the PR description for future readers who scan the file positionally.

Strengths

• Proactive, documented secret-exposure scan in the PR body before publishing to a public-facing branch — good practice for a chart repo that serves real customers.
• Verification steps (helm lint, helm template) are cited with concrete commands rather than asserted.

Recommended Action

Looks good — no blocking findings. Since this is self-authored, please get a human (or distinct-identity) sign-off before merging to gh-pages, given it's the live public Helm repo.
