Desktop terminal access should behave like an IDE: active project sessions open a bottom panel in the session working directory while keeping a full terminal tab available for dedicated use. The panel has constrained resizing and cleanup so session tab state remains isolated, and terminal guidance points users to the bundled claude-haha command for extension setup.
Constraint: Desktop bundles the user-facing CLI as claude-haha while claude-sidecar remains internal
Rejected: Always opening a standalone terminal tab | loses the current project context and diverges from common IDE behavior
Rejected: Exposing claude-sidecar in terminal guidance | it is an internal launcher, not the supportable user command
Confidence: high
Scope-risk: moderate
Directive: Keep bottom terminals keyed by session id and pass session workDir/projectPath into spawned terminals
Tested: bun run check:desktop
Tested: git diff --check
Tested: Computer Use E2E against built macOS app during implementation
Not-tested: bun run quality:pr is blocked by existing branch policy requiring allow-cli-core-change approval
Workspace inspection was visible only as a side panel, while file restore still lived behind the older per-message rewind affordance. This adds a chat-flow change card for the completed turn, keeps undo routed through checkpoint rewind, and tightens the workspace split layout so narrow and fullscreen windows keep both chat and file preview usable.
Constraint: Current session file changes must work for non-Git directories when transcript tool edits are available
Constraint: Workspace preview must remain right-docked without horizontal overflow across narrow and wide desktop viewports
Rejected: Keep only hover rewind | users could not clearly see what the current turn changed before undoing it
Rejected: Use Git as the only changed-file source | many desktop sessions run in temporary or non-Git directories
Confidence: high
Scope-risk: moderate
Directive: Keep checkpoint rewind as the source of truth for undo semantics; workspace diffs are a preview surface, not the restore authority

Not-tested: Native Tauri packaged app window chrome behavior
Expose a workspace inspector for desktop sessions so users can browse the active project, preview files, inspect session-derived changes, and review diffs even when the work directory is not a git repository.
Constraint: The workspace view must work for temporary and non-git project directories.
Rejected: Rely only on git status | non-git sessions would lose the changed-files surface.
Confidence: medium
Scope-risk: moderate
Directive: Keep undo semantics separate from workspace browsing; checkpoint-backed rewind should remain the source of truth for rollback.

The desktop task bar used a single global task store, but session switches
could leave it pointed at the previous conversation. Re-entering an already
connected session skipped task refresh entirely, and changing task list IDs did
not clear stale tasks before the next fetch resolved.
This change refreshes CLI tasks on every session activation, clears stale task
state immediately when the tracked session changes, and locks that behavior
with regression tests around reconnect and cross-session task isolation.
Constraint: The current desktop task bar architecture uses one shared CLI task store across sessions
Rejected: Per-session task store refactor | too broad for a targeted bug fix
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: If tasks become session-scoped later, re-evaluate the eager refresh in connectToSession before removing it

Not-tested: Manual desktop UI verification against a packaged app build
Desktop sessions were missing a visible request_access approval path and could
mis-detect their own app window as an unapproved frontmost target, which caused
Computer Use clicks to fail even after opening the intended app. On macOS, text
entry was also split across inconsistent clipboard and keystroke paths, making
Electron inputs unreliable for Chinese and short strings.
This change adds a desktop approval bridge over the existing session websocket,
renders a dedicated desktop approval modal, threads the real desktop bundle id
into the Computer Use executor, and switches macOS clipboard typing onto the
native pasteboard plus system paste shortcut path. It also makes tool error
results expandable in the desktop chat UI so frontmost-gate failures are fully
visible during debugging.
Constraint: Desktop sessions run the CLI over the SDK websocket path, so Ink tool JSX dialogs are not visible there
Constraint: macOS IME and Electron text inputs are unreliable with pyautogui.write and generic hotkey synthesis
Rejected: Reuse CLI setToolJSX dialogs in desktop mode | no transport for mid-call Ink UI over the SDK bridge
Rejected: Keep shell pbcopy/pbpaste for clipboard typing | inconsistent with NSPasteboard path and less reliable for Chinese text
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep desktop Computer Use approvals and macOS text-entry behavior on a single bridge/path; avoid reintroducing separate CLI-only and desktop-only codepaths for the same action

This bundles the pending desktop/server team-session fixes with the local adapter recovery changes already in the worktree. The team path now keeps teammate membership stable under concurrent spawns, surfaces real teammate identities in the desktop UI, and allows direct interaction with member transcripts. The adapter changes recover automatically when stale thinking signatures invalidate an existing session.
Constraint: Team config writes can happen concurrently while multiple reviewers spawn in parallel
Constraint: Desktop member views must follow mailbox/transcript semantics rather than hijacking teammate runtime sessions
Rejected: Keep relying on config.json alone for member discovery | in-process teammates can be lost after concurrent writes
Rejected: Open teammate sessionIds as normal desktop sessions | would attach a second CLI instead of the running teammate
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Preserve locked team-file mutation for any future teammate registration path and keep teammate labels sourced from member names before agent types

This folds together the desktop-side fixes needed before broader rollout.
Session resume no longer deadlocks waiting on init, Mermaid and inline image
output render inside chat, task and sub-agent state stay visible during
execution, local build/release paths are safer, and Feishu/Telegram now expose
lightweight mobile commands (/help, /status, /clear) without adding a new
adapter-specific protocol.
Constraint: Desktop releases must publish updater artifacts from non-draft GitHub releases
Constraint: IM commands need short, phone-friendly responses and low operational complexity
Rejected: Add a dedicated IM command API surface | re-used existing slash commands and session/task REST endpoints to keep adapters thin
Rejected: Wait for task_update push events in WebUI | added low-risk polling because the current frontend ignores that event path
Confidence: medium
Scope-risk: broad
Reversibility: clean
Directive: Keep IM command replies terse and mobile-first, and merge local fallback slash commands when server-provided lists are partial
