Reads the aionui-panel settings namespace's rightPanel provider choice: while
it resolves to 'aionui-panel', the whole sidebar does not mount (host
settings.get reports externalDisable, the client mount gate skips mounting
and the link/open-path/turn-tail takeovers step aside). Live via the
settings/document-updated push (best effort; deployments without the
'remote' service fall back to boot-time evaluation). No new user-facing
setting — the aionui panel card remains the single source of truth.
- state: side-store per conversation, injected as a prop instead of a module singleton
- host: schemastery Config (read/media/list/terminal limits) resolved from cordis config
- shape: types/exports/peerDependencies for the web profile + plugin-shape spec
- fix: split divider emits incremental deltas so drags track the cursor 1:1
- docs: README refresh
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).
