Batch-resolve creator names at stage 6 start. | Semantic search now surfaces results for creator-name queries and tag-specific queries. Batch resolution avoids N+1 lookups during embedding. Reindex-all endpoint enables one-shot re-embedding after text composition changes. | Yes | agent |
 | D024 | M014/S01 | architecture | Content model for sections with subsections | Sections with subsections use empty-string content field; substance lives in subsections | Avoids duplication between section-level content and subsection content. The section heading serves as H2 container; all prose lives in subsection content fields. Sections without subsections use the section content field directly. | Yes | agent |
+| D025 | M015 | architecture | Search query storage and popular searches architecture | PostgreSQL search_log table + Redis read-through cache with 5-min TTL | PostgreSQL gives full historical data for future analytics (zero-result queries, time-of-day patterns). Redis cache prevents DB query on every homepage load. 5-min TTL balances freshness with load. Volume is tiny at current scale. | Yes | collaborative |
