 `session_archive` advertises the v1 directory-state archive API: `POST /sessions/archive`, `POST /sessions/unarchive`, and `GET /workspace/:id/sessions?archiveState=active|archived`. Archived sessions cannot be loaded or resumed until they are unarchived.
 
+`workspace_qualified_rest_core` advertises plural core REST routes under `/workspaces/:workspace/...`. The selector resolves as exact workspace id first, then as a URL-encoded absolute cwd after canonicalization. On single-workspace daemons, `workspaces[]` is absent unless `multi_workspace_sessions` is also advertised, so clients use `capabilities.workspaceCwd` as the cwd selector. Trust status and trust request routes are available for registered untrusted workspaces; file read routes follow the existing filesystem read policy. File write routes and all other plural core routes require a trusted workspace and return `403 { code: "untrusted_workspace" }` when the selected runtime is untrusted. This plural trust gate is intentionally stricter than some legacy primary-workspace read routes, which keep their existing compatibility behavior and are not drop-in replacements. This tag covers the core file, status, settings, permissions, trust, lifecycle, MCP control, tool toggle, memory, workspace agent CRUD, and session storage surfaces. It does not cover auth, voice, extensions, ACP/WebSocket transport, or channel-worker routing.

 `session_lsp` advertises `GET /session/:id/lsp`, the read-only structured LSP status snapshot for daemon clients. Older daemons return `404`; pre-flight this tag before exposing remote LSP status.
 
 `session_status` advertises `GET /session/:id/status`, the live bridge summary for a single session by id (`clientCount` / `hasActivePrompt` and the core fields). Older daemons return `404`; pre-flight this tag before polling a single session's status instead of scanning the full session list.

 ### `GET /workspace/:id/sessions` and `GET /workspaces/:workspace/sessions`
 
-List sessions whose canonical workspace matches `:id` or `:workspace`. The path parameter first resolves as an exact workspace id and then as a URL-encoded absolute cwd. `GET /workspaces/:workspace/sessions` is a plural alias with the same response shape. Primary workspaces include the existing persisted/live merge: the default list is active sessions from `chats/`; pass `archiveState=archived` to list archived sessions from `chats/archive/`. Trusted non-primary workspaces include active persisted sessions from their own `chats/` store and merge matching live summaries without duplicates; if no active persisted sessions exist, the route preserves the previous live-only cursor behavior. Non-primary workspaces still reject archived, organized, or grouped queries. Untrusted non-primary workspaces return `403 { code: "untrusted_workspace" }`. `archiveState=all` is not supported in v1. Primary and persisted-backed lists keep the existing numeric `cursor` semantics; the no-persisted non-primary live fallback keeps its existing opaque live cursor.
