Adapted to HEAD's unified editor+explorer tab: the reveal gesture now
opens the editor home tab (the files window) instead of the deleted
explorer type. PR's revealInExplorer implementation, produced-files
engine-data selector, and tests are retained verbatim.
The open-path interception reroutes EVERY chat-side file open into the
sidebar editor, including the stock "Show in folder" gesture: the
ui-deliverables row passes "." (resolved to "<cwd>/." by the chat view),
so clicking it opened a bogus editor tab for the workspace directory
(host error: '"..." is a directory').
- openpath-intercept: detect the folder-reveal gesture ("." / "./" /
"<cwd>/.") and route it to a new revealInExplorer dep instead of the editor.
- intercept: revealInExplorer switches to the explorer tab (expanding the
panel), expands the produced files' parent directories, and highlights /
scrolls to them; the intercepted produced-files row now also renders its
own "Show in folder" button when files are hidden.
- produced-files: selectProducedFiles reads the engine Turn data
(owner.turn.data.get("deliverables")) — the same source ui-deliverables
uses — with the node replica as fallback. The old code read owner.nodes,
which the real TurnTailOwnerProps ({turn, seq, openFile}) does not carry,
so the takeover never claimed the chain.
- state: transient `revealed` set (never persisted) plus a revealPaths
reducer that expands ancestor directories.
- ExplorerView: highlight + scroll revealed rows; Sidebar/tabs/service
thread `revealed` through TabComponentProps.
- tests: folder-gesture routing, engine-data selector, wiring seat, zh/en copy.
Host half (src/index.ts): /sidebar/api JSON API (session cwd, fs tree/read/
write, git status/diff/stage/commit/branch/log/show), /sidebar/file media
route, /sidebar/ws/terminal WebSocket over node-pty; routes share the /api
trust fence (Host-header loopback or connection.trustedHosts).
Client half (src/client): portal-mounted right panel with a per-session
split-pane workbench (recursive row/col splits, draggable dividers, tab
drag-move), tab bar with max-width 160px + plus-menu (explorer/git/terminal
multi-open rules), lazy file explorer rooted at the session cwd, editable
text editor (dirty dot, Ctrl/Cmd+S), image + Markdown preview, xterm
terminal with reconnect, and a VSCode-style git panel. Per-session state
persists to localStorage (dsh-sidebar:v1:<sessionId>). Intercepts the chat
turn-tail produced-files row (priority -1 chain entry) to open files in the
sidebar. UI styled with the dsh --dsw-* theme tokens and ui-primitives.
Build: tsdown emits the host lib plus the __ModuleLoader__ client bundle
(externals = module table words; xterm/css inlined). Tests: 19 unit + smoke
specs (pure state/tree/git parsers + real git/fs integration).
