The uid counter is module-global and resets on every reload, while the
persisted split tree keeps its old ids (pane:1, split:1, ...). A split
created AFTER a reload minted a fresh "pane:1" beside the persisted
"pane:1"; mapLeaf then visited BOTH leaves, so every open (explorer click,
produced-files chip) landed the tab in both panes of a top-bottom split.
- loadState seeds the counter past the raw persisted ids before sanitize
- setSession re-seeds on cache hits (another session's smaller max must
not leave the counter below this session's ids)
- sanitize re-ids stale duplicate pane/split ids (heals states already
corrupted) and follows the activePane rename
- openTab falls back to the first pane when the active pane is gone
instead of silently dropping the open
Unit tests cover the re-id heal and the stale-activePane fallback;
verified end-to-end in headless Chrome: a state with two "pane:1" leaves
loads healed and a file click lands in exactly one pane.
- Tabs, the + menu, and empty-pane cards carry per-type icons (folder /
branch / terminal / code file); a terminal glyph joins the icon set
- Hovering an explorer row reveals an @文件 button at the far right that
appends @<relative path> to the composer draft (session-scoped input
service, space-separated append)
- Right-clicking a row opens a context menu: copy relative / absolute
path (writeClipboard + transient in-row "copied" label)
- Rows become div role=button (Enter/Space) to host the inner button;
relativeTo helper unit-tested
The close frame was sent on every unmount, so switching conversations (or
refreshing) killed the shell even though the tab was still open; coming
back spawned a fresh terminal. Now the unmount close frame only fires when
the tab is truly gone (checked against the per-session store state), so a
bare unmount hands the process to the host's reconnect grace and the next
connect reattaches the SAME shell with its transcript. Closing a tab
releases the quota immediately: the socket-open path keeps the close
frame, and a new pty.close API covers the socket-down (reconnect loop)
case that previously left a 30s zombie holding the quota.
The host also records the spawn cwd and respawns when a reconnect carries
a different authoritative cwd — the page-load hydrate race can attach the
real session cwd after the first connect fell back to the process cwd, and
a shell in the wrong directory must not linger.
- markdown tabs open in rendered preview with a 预览/编辑 segmented toggle;
edit mode uses the CodeMirror source editor (markdown highlighting), the
preview renders the live unsaved draft, and the editor stays mounted while
previewing so edits survive the toggle.
- an empty pane shows openable-type cards (explorer / git / terminal, the
same options as the + menu, terminal dimmed at the cap) instead of the
bare 'this pane is empty' message; clicking a card opens the tab.
- the + button sits immediately right of the last tab (sticky at the
scrollport's right edge when the tab row overflows, so it stays
reachable).
- cwd resolution falls back (attached header → client summary cwd → process
cwd) across the JSON API, media route and terminal upgrade, so explorer/
git/terminal work from first paint instead of 'session ... has no working
directory' while the web client hydrates the session (refresh-only fix).
- terminal client threads the summary cwd into the WS URL and stops the
reconnect loop after three unreasoned failures, showing the close code
with a manual retry; a 1011+reason refusal already showed the reason.
- white screen: persisted state is structurally sanitized on load (malformed
shapes fall back to default) and the restored width is clamped to the
viewport; the layout margin is capped at the viewport; the client entry
wraps every lifecycle step in try/catch and pins a visible diagnostic bar
on load/mount/interception failure instead of failing silently.
- editor: textarea replaced with CodeMirror 6 — line wrapping, per-extension
syntax highlighting (js/ts/jsx/tsx, json, python, html, css, xml, yaml,
sql, java, c/c++, rust, go, php, shell, toml, nginx, dockerfile,
properties), one-dark theme, dirty dot + Ctrl/Cmd+S save kept.
- tests: +9 (cwd fallback chain over the API route, state sanitization,
language mapping); 36 pass, typecheck + build + vm materialize clean.
- Root cause of the endless 'disconnected, reconnecting' banner: pnpm
strips the executable bit from node-pty's prebuilt spawn-helper, so every
spawn failed with posix_spawnp failed and the client retried forever.
ensureSpawnHelper() restores 0755 at plugin activation (mirrors
dsh-pty-local's postinstall; works for link installs too). Verified
against the live GUI: terminal now connects and echoes.
- TerminalView stops auto-reconnecting on a server refusal (close 1011 with
a reason): shows the reason plus a manual retry instead of spinning.
- defaultShell() also guards an empty SHELL.
- New sessions open at half the viewport width; width clamping now allows
filling the window, and a header fullscreen button expands the sidebar to
the full viewport (toggle restores half).
- Middle-click on a tab closes it (auxclick button 1, autoscroll
suppressed).
- Tests: +2 (shell fallback, spawn-helper exec bit idempotent).
- Split panes by dragging a tab to a pane edge (left/right/up/down zones
with a drop overlay) or into the center to merge; the toolbar split
buttons are gone (split-pane.tsx, state.ts moveTabToEdge/insertLeafAt).
- The header close button is now a collapse button; the expand button on
the right edge stays visible whenever the panel is collapsed, so the
sidebar can always be reopened (Sidebar.tsx, locales collapse/expand).
- Styles now follow the DSH web-styling rules exactly: --dsw-alias-*
semantic colors (state-error/warn tokens), --dsw-font-* typography roles
(size + line-height paired), --dsw-shadow-lv* elevation, no color
literals or static palette values (sidebar.module.css).
- Tests: +3 for moveTabToEdge (edge split, center merge, self reorder).
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).
