Walkthrough

The workflow sends Slack notifications when a run fails and SLACK_WEBHOOK_URL is configured. The notification includes workflow metadata and optional commit information. versions.sh adds a retrying fetch helper and uses it for Ghost lockfile and GitHub release metadata requests.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 4ca76

This change adds Slack alerts for failed update runs and makes external version metadata requests retry safely until release assets are available. The current implementation has no identified merge-blocking risk.

Inline comments:
In @.github/workflows/update.yml:
- Line 244: Validate SLACK_WEBHOOK_URL before the curl invocation and reject any
value that does not use the HTTPS scheme; only send the webhook request after
this validation succeeds.
- Around line 241-244: Update the curl invocation in the Slack webhook pipeline
to set explicit connection and total-request timeouts, while preserving the
existing headers, request body, webhook URL, and failure reporting behavior.

In `@versions.sh`:
- Line 148: Update the release-fetch logic around fetch and the tarballUrl
lookup so retries continue until the target ghost-$fullVersion.tgz asset is
present, not merely until the GitHub API returns HTTP 200. Ensure the retry
condition validates the extracted asset URL before allowing the script to
proceed.
- Around line 6-25: Update the curl invocation inside fetch to enforce both
connection and total-request timeouts on every attempt, while preserving the
existing retry loop and error handling. Configure finite deadlines so stalled
connections return control to fetch and proceed through its retries.
