-Opening a workspace never changes the sidebar. A workspace row, a command-search result or a workspace in the chat panel opens that workspace in the right pane, as the Integrations row opens Integrations, and the open workspace's row is current: Dashboard on example data, Workflows on live data. Every workspace page sits on one tab frame, listed with the data modes that serve it in `WORKSPACE_TABS`: Dashboard, Issues, Changelog and Logs from Paper, with one shared split for a record's details; Tables, Files, Knowledge bases and Workflows, live-only ports of the legacy pages with breadcrumbs as the only folder traversal; and Settings, the legacy workspace settings sections beside their own navigation in the organization Settings navigation's pattern. `hidden` keeps Dashboard, Issues, Changelog and Tests out of the live tab bar, and out of chat and mentions, until Emir's pass; each page still answers when its flag is on and is not found when it is off (Issues, with no backend, always on live data). See [workspace UI](docs/workspace-ui.md). Chats belong to the organization, and the composer's slash offers Skills.
+Opening a workspace never changes the sidebar. A workspace row, a command-search result or a workspace in the chat panel opens that workspace in the right pane, as the Integrations row opens Integrations, and the open workspace's row is current: Dashboard on example data, Workflows on live data. Every workspace page sits on one tab frame, listed with the data modes that serve it in `WORKSPACE_TABS`: Dashboard, Issues, Changelog and Logs from Paper, with one shared split for a record's details; Tables, Files, Knowledge bases and Workflows, live-only ports of the legacy pages with breadcrumbs as the only folder traversal; and Settings, the legacy workspace settings sections beside their own navigation in the organization Settings navigation's pattern. The `platform-preview` feature flag (off by default) holds what waits for Emir's pass: `preview` tabs in `WORKSPACE_TABS` (Dashboard, Issues, Changelog and Tests) and Home's Needs your attention and Workspaces. While it is off, live data lists none of those tabs, chat and mentions offer no way in, each page answers not found, and Home reads and renders neither section; while it is on, each tab still needs its own flag (Issues, with no backend, is never served on live data). Hold new design-pending UI behind the same flag rather than a code switch. See [workspace UI](docs/workspace-ui.md). Chats belong to the organization, and the composer's slash offers Skills.
 
 The Workflows canvas is the one surface that keeps legacy pixels: the user required blocks, handles, edges, loops and parallels to look exactly as they do in the legacy editor. Its folder copies the legacy canvas views and is exempt from the styling rules it cannot meet; the chrome around it follows this contract. Its seam folders are the only ones that may bundle the blocks and tools registry. See the [ownership map](docs/component-ownership.md).
