✅ Gate recommendation: approve.
The current revision addresses both prior findings: V1 now fails closed for cross-corpus leaves and explicitly assigns same-query attachment to the trusted planner. The single-corpus wire scope matches #8937, and the schema/build integration compiles cleanly.

Distributed FTS executors need one query-bound, corpus-wide BM25 statistics payload so workers searching different index segments can produce comparable scores.
This is part of #8937 and supports the downstream Doris use case described in apache/doris#67435.
