Why: Account disable could be followed by late Backend business writes, API key creation could implicitly create users, account bootstrap locks could invert, and directory cursors were process-local or leaked out-of-scope changes. Evidence: Local go test ./... and isolated PostgreSQL package suites passed on the staged candidate; exact committed-head SELF replay and stage 6 human review remain pending. Impact: Adds final account transactions and external-effect checks across HTTP, Host, Bus and run manager; tightens API key issuance and persists versioned cursor signing. Delegated RDM rename still needs the separately proposed real-operator contract, so A1 and stage 6 are not complete.

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。
