docs(007): public projection of SELECT-004 promotion

[scrimshawlife-ctrl]

Summary

Public projection of the completed SELECT-004 promotion. Source commits on Spark are 43486ff (scored decision) and 098ece4 (BEST pointer). Those commits are not pushed verbatim: their history is not origin/main, and the scored paragraph names a host container.

This PR adds one redacted receipt. It does not move BEST, train, score, or change the reserve.
