• Tests run: name the command (e.g. npm test, cargo test) and the result.
• If this closes a work item, the body contains a Closes #N directive.
• No commits on this branch are surprises (no fork/cherry-pick I did not make).
• No secrets / credentials / large binaries staged.

Summary

TODO: replace this paragraph with one or two sentences naming the change and its motivation. Reviewers read this first.

Test plan

• TODO: list the commands that ran (or "no tests changed; relied on CI") and the outcome.

Closing: this is a stray duplicate. The branch wk9020 was a local working branch I used to resolve #9020's merge conflict, and it got picked up and attached as a draft PR at #9020's OLD head (ee58357) — including three #[ignore]d probe files whose own header reads "LOCAL DIAGNOSTIC PROBE — not for commit", which I removed as part of the resolution.

The real work is #9020 (session/merry-raven-395), now at 9306822 with the conflict resolved: 99 roster rows, main's #8975 header correction preserved, and the probe files dropped. Nothing here is lost by closing this.
