v0.1.1

custom-domain-checks 0.1.1 (the version in package.json): the GitHub App service in server.js.

Changed

• What the App writes into repositories now uses the CustomDomain™ brand: the check run summary
  ("Domain health checks by CustomDomain™"), the closing line of the check run text and the tracking
  issue ("Run continuously by CustomDomain™ Checks"), the DNS resolution failure hint, and the
  description of the domain-health label it creates.
• Unchanged on purpose: the App name in the registration manifest (Custom Domain Checks) and the
  registration pages that refer to the App by that name, because the name is fixed when the App is
  registered on GitHub.

The hosted instance picks this up when it is redeployed.

v0.1.0

custom-domain-checks 0.1.0 (the version in package.json): the GitHub App service in server.js.

The first tagged release. server.js is unchanged since the service was written on 2026-07-15; this release
gives it a version and records what it does.

The service

• A GitHub App that finds a repository's custom domain from its GitHub Pages configuration, a CNAME file or
  a customdomain.yml list.
• Nine health signals: DNS resolution, record type, target correctness, whether Pages is serving, domain
  verification, CAA compatibility with Let's Encrypt, certificate validity and expiry, HTTPS enforcement, and
  DNS hygiene.
• A Domain health check run on every push, with a pass, warn or fail per signal and the record to change,
  plus a Re-check button.
• One deduplicated domain-health issue that is updated in place and closed when the domain recovers.
• Webhooks verified with a constant-time HMAC-SHA256 comparison, queued, and answered 202 at once.
• App registration through the GitHub App Manifest flow at /github-app/register, and a health endpoint at
  /github-app/health.

Status

• The hosted service is deployed and answers https://customdomain.ai/github-app/health with
  {"ok":true,"provisioned":false,"app":null}: the public App is not registered yet, so running your own
  instance is the way to install it today.

This repository

• package.json with the version (private, no dependencies), this changelog, and the README and AGENTS.md
  in the shared CustomDomain™ structure.
