## Session list rules
### Layout-mounted session-list lifecycle
`MainLayout` and `VSCodeLayout` each call `useSessionListSync({ isVSCode })` directly and unconditionally, outside Sidebar visibility, responsive, editor, settings, and compact-view branches. The hook selects the real topology inputs, publishes complete directory bootstrap demand through `ChildStoreManager`, refreshes the global list once per layout mount, refreshes topology additions (including all VS Code directories on its first mount), coalesces OpenChamber control events for 500ms, and supplies a memoized complete global active+archived input to authoritative cleanup. MainLayout includes available worktrees; VS Code intentionally excludes them. Sidebar-local `session-created` worktree discovery is separate and full-app-only.
### Directory bootstrap scheduling
`ChildStoreManager` is the single owner of directory bootstrap scheduling. Consumers publish demand; they must not start bootstrap from row mount effects.
