Why: plan U6 vector slice (KTD11 correctness step) - same-dimension vectors from different models must never mix, and PG tiers should run filtered exact top-k in the database instead of scanning every row in-process. Evidence: full suite green on SQLite and real PostgreSQL 18.6 with pgvector (35 packages each tier) - pgvector_test covers model-identity and dimension isolation, update/delete atomicity (BLOB and vec_pg swap together), shared top-5 with score monotonicity, Recall@10 = exact-scan parity, deny-all predicate leakage; storage-migrate tests green after excluding the derived vec_pg column. Impact: v25 migration adds model/content_hash columns and (PG, best-effort DO block) the pgvector extension plus vec_pg column - absence degrades to in-process scan; UpsertKnowledgeVectorExt dual-writes BLOB (cross-tier authority) and vec_pg; SearchKnowledgeVectorsModel/SharedModel filter by model identity and use SQL exact top-k (ORDER BY vec_pg <=> q) with automatic degradation; embedders expose Model() and the rag pipeline threads it through indexing and both retrieve paths; storage-migrate excludes vec_pg as a derived column.

Agent-System-Backend
对话系统后端：Go 模块化单体，默认构建为单二进制（go:embed 内嵌前端与嵌入式 SQLite 存储）。组合 Agent-Native / Agent-Squad / Agent-Intent 生态，依赖 agent-system-core 契约。
契约与架构见 Agent-System-Documents 设计方案与架构文档；开发规范见 development-guidelines（Dev 仓 development/guidelines）。本仓为 Agent-System 多仓组合的组成部分。
