Each release now posts one Slack message. The result notices reply in its thread, using the ts output of the start post.

• Failure notices are also broadcast to the channel (reply_broadcast). Success stays in the thread and adds a ✅ reaction to the start notice. This needs the reactions:write scope on the Slack app; the step is non-fatal until it is granted.
• If the start notice never posted, thread_ts renders as YAML null. The Slack client drops null fields, so notices post to the channel as before. An empty string would be sent as-is, which is why null is used.
• thread_ts is quoted so YAML keeps the timestamp a string rather than a float.
• Notices that can only fire before the start notice exists (failed checks or tests, and one-message paths) are unchanged.

Summary by CodeRabbit

• Notifications
  • Release successes are posted in the Slack thread started by the release notice, with a ✅ reaction added to that notice when a timestamp is available. Failures are posted in the thread and broadcast to the channel. Without a start timestamp, release updates are posted without threading. Prerelease notices remain single channel messages.
• Documentation
  • Updated release workflow documentation to describe threaded release updates, channel-broadcast failures, and the success reaction.

Walkthrough

The release workflow exposes the Slack start-notice timestamp to the notify job. Release success and failure notices use that timestamp when available. Failures are broadcast, while successful releases add a check-mark reaction to the start notice. The release documentation describes these notification behaviors.

Changes: Release Slack notifications

Layer / File(s)	Summary
Capture and use the start-notice timestamp .github/workflows/publish.yml, RELEASING.md	The publish job exposes the start-notice timestamp as slack-ts. The notify job uses it for release success and failure notices when available. Failures are broadcast; successful releases add a check-mark reaction to the start notice. Without a timestamp, release notices are not threaded. The documentation describes these behaviors.

Review details

Systems and components

• observed — RELEASING.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in RELEASING.md: The “Record” description now specifies where publish results and failures are posted and that success adds a ✅ to the start notice; the previous description only listed Slack start, success, and failure notices.
• observed — Modified behavior in .github/workflows/publish.yml: The release publish job adds the start Slack notification’s timestamp as a slack-ts output for downstream jobs.
• observed — Modified behavior in .github/workflows/publish.yml: The release-start Slack step gains the slack-start ID, which supplies the timestamp exposed by the publish job.
• observed — Modified behavior in .github/workflows/publish.yml: The notify job defines THREAD_TS from the publish job output, quoting a present timestamp for YAML parsing and using null when no start timestamp is available.
