One INFO line per slow search naming the path taken (fts_cjk / fts5 / trigram / like_scan), elapsed time, row count, and the query. The 2026-07 session_search investigation needed turn-trace archaeology plus workload replay to discover that short-CJK queries were full-scanning the table — with this line the next routing regression is a journalctl grep. Threshold: sessions.search_slow_ms (default 1000ms; 0 logs every call), bridged to HERMES_SEARCH_SLOW_MS. Salvaged from PR #65544 (adapted to the v23 schema in follow-up commits).
