Notes

Initially, this PR was to solve WC-428, but @jarosenb assures me that the real issue (private) is unrelated to this. But, I still would have preferred this solution to #1109, so I'm tempted to merge it.

I don't use remote agents now¹, but this PR still seems good to me.

Footnotes

1. Cursor made local agents more convenient. ↩

I re-reviewed again.

Pros:

• Reverts a change I should not have made.
• Still supports remote agents.
• Local and Remote servers are unaffected.

Cons: 🤷

Merging.

Local Core-CMS servers are affected by Elasticsearch downgrade. I'm pretty sure I'm the only one with one of those… so we're good.

If someone complains their local Core-CMS broke, point them to me or have them delete core_cms_elasticsearch volume.

A local Core-Portal would be unaffected, cuz it has its own elasticsearch.
