Conversation rows always reserved space for the more-actions button, and the active row kept it visible. The button now replaces the right-side timestamp only on hover, keyboard focus, or while its menu is open, leaving more room for conversation titles and timestamps by default.
Release note: 会话列表仅在悬停或键盘聚焦时显示更多操作按钮，更新时间默认更靠右，为会话标题留出更多空间。
Local conversations can now continue in a new branch after stable content is persisted. Each branch uses new conversation and message IDs, keeps its source visible, and remains independent without copying Tasks, queue items, runs, memories, or artifact ownership.
Conversation Task rows are also denser, align status markers at the right edge, and use an accessible checked success marker without redundant completion text.
Release note: 本地会话现在可从“在新会话中继续”创建独立分支并显示来源；Task 子项布局更紧凑，状态统一显示在右侧。
Scheduled tasks previously created separate visible work for each run and lacked one conversation-backed product identity. Custom tasks now create or reuse one stable Task and Conversation, reuse that identity across triggers, and write text results back with Task provenance.
Tasks default to Execute while preserving the configured Runtime, tool authorization, and high-risk approval boundaries. Schema v22 backfills existing schedules to stable Task and Conversation links without deleting historical runs.
The conversation list, conversation Task strip, and Task Center now expose the same Task, with localized status metadata, overflow-aware titles, and shared schedule controls.
Release note: 现在可以创建关联当前或新会话的定制计划任务；重复执行会复用同一 Task 并将文本结果回写会话，左侧会话列表和 Task Center 可直接查看和管理。
Replace the flat features directory with document-type and functional-domain navigation, update repository-wide links, and add a top-level documentation index.
Define Task, Conversation, Job, Subjob, Run, Scheduled Task, Goal Task, and Task Center in one canonical document set. Keep Smart Heartbeat ownership separate and leave future partitioned memory explicitly undesigned.
