Why: trimOldest dropped single messages without tool-pair awareness — after leading users were evicted it could orphan tool results or leave dangling calls (acceptance clause 2's product-side gap). Evidence: go test -count=1 ./... green; TestTrimOldestKeepsToolPairs (pairing holds across repeated trims), TestTrimOldestDropsLeadingOrphanToolRun, TestTrimOldestStopsWhenGroupCrossesCurrentTurn, TestPrefixHashStableForIdenticalInput; native pins carry the spill and cache-contract work (Agent-Native#25). Impact: trimming now evicts whole tool groups; the window may be slightly exceeded when a group would cross the current turn — pairing is never broken. Report.Truncations still records the count.

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。
