Windows folder selection can surface drive roots as D:, which Node treats as drive-relative instead of the absolute D:\ root. Normalize drive-root inputs before resolving launch directories, filesystem access roots, transcript metadata, and workspace paths. Use path.relative containment checks so drive roots and child projects remain distinct in session grouping and file access.
Constraint: Windows drive-root inputs may arrive as C:, D:, or any other single-letter drive prefix
Rejected: Special-case only D: | every Windows drive letter has the same drive-relative semantics
Confidence: high
Scope-risk: moderate
Directive: Keep Windows drive-root normalization centralized; do not reintroduce string-prefix containment checks for workspace roots

Related: #601
File browsing and workspace trees were treating every dot-prefixed entry as hidden, which made project files such as .env.example impossible to select through the desktop file surfaces. The fix keeps normal dotfiles and project folders visible while still hiding VCS metadata directories such as .git.
Constraint: VCS internals should stay out of user-facing file trees even when dotfiles are visible
Rejected: Add a UI toggle for hidden files | issue asks for file lists to include dot-prefixed project entries by default
Confidence: high
Scope-risk: narrow
Directive: Do not reintroduce blanket dotfile filtering on filesystem browse, workspace tree, or path completion paths

Not-tested: desktop browser visual smoke
Desktop file mentions should follow the workspace the user opened, but
the filesystem browser only trusted the home and temp roots. Register
workspace roots after repository context, session creation, and session
git-info resolution so Windows projects on another drive can be searched
without turning the browse API into arbitrary disk access.
Constraint: Windows users can open repositories outside C:\\Users, such as D:\\workspace\\code\\cc-haha
Constraint: Filesystem browse must not become an unbounded local disk reader
Rejected: Add a global user-configurable filesystem whitelist | broader product and persistence surface than this bug needs
Rejected: Allow every requested browse path | would bypass the intended filesystem boundary
Confidence: high
Scope-risk: moderate
Directive: Register only workspace roots that the server has already resolved through session or repository flows

Desktop search results were visually misleading when many directories shared the same basename, because the UI emphasized the basename and the server ranking allowed deep basename matches to outrank direct path-prefix matches. This makes search rows show the insertable relative path and ranks direct path-prefix matches before unrelated same-name directories.
Constraint: Desktop @ file suggestions should match the CLI mental model for path search.
Rejected: Keep basename plus parent-path rows | it hides the distinction between src/, src/hooks/, and desktop/src in the primary text.
Confidence: high
Scope-risk: narrow
Directive: Preserve path-prefix ranking ahead of basename-only matches for directory searches.

Desktop @ file search was recursively walking the filesystem with a local skip list, which let Python and Node generated directories leak into results and diverged from CLI behavior. Route candidate discovery through the same git-first model: tracked files, untracked files with exclude-standard, and ripgrep fallback for non-git folders, then derive selectable directories from those candidates.
Constraint: Desktop picker must select both files and directories without surfacing ignored project artifacts.
Constraint: No new dependencies; reuse the existing git, ripgrep, settings, and ignore utilities.
Rejected: Maintain a hardcoded directory denylist | it would drift from CLI and miss project-specific ignore rules.
Rejected: Full recursive readdir scanning | it ignores git index semantics and makes large dependency trees visible.
Confidence: high
Scope-risk: moderate
Directive: Keep desktop @ file candidate discovery aligned with src/hooks/fileSuggestions.ts before changing ranking or ignore behavior.

Not-tested: Native Windows/Linux manual UI smoke; path handling relies on cross-platform git/ripgrep wrappers and normalized relative paths.
Desktop @-mentions were collapsing filesystem browse failures into an empty
state, which made /private/tmp aliases on macOS look like real empty
directories. The server now treats /private/tmp as the same temp root as
/tmp on Darwin, and the menu surfaces explicit access/load errors instead of
pretending the directory has no files.
Constraint: Desktop browse/file APIs must stay restricted to approved roots
Constraint: Native macOS pickers and realpath() may canonicalize /tmp to /private/tmp
Rejected: Expanding filesystem access to arbitrary system paths | too broad for this targeted fix
Rejected: Keeping silent empty-state fallback | hides permission and path bugs from users
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep filesystem error states visible in the composer; do not collapse API failures back into empty-directory messaging

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

- Input @ in composer to open file search popup showing project root
- Filter files/directories by typing, navigate with keyboard or mouse
- Click directory to enter subdirectory, type / to navigate deeper
- Enter selects item and inserts path text at cursor, popup closes
- Parse filter path (e.g. @src/components/) to auto-navigate and search
- Desktop: filesystem browse/search API supports includeFiles and search
- Web: directory tree browser with real-time search filtering
The desktop app now keeps the composer stable while turns are active,
reduces low-signal tool noise in the transcript, restores project context
under the composer after session creation, and relies on the CLI's own
permission requests instead of injecting broader desktop-side Bash asks.
This also brings in the supporting desktop app source tree and the server
routes/session metadata needed for git info, filesystem browsing, session
resume, slash commands, and SDK-backed permission bridging so the UI can
operate as a coherent feature instead of a partial patch.
Constraint: Desktop transcript needs to stay usable during long multi-tool sessions without hiding file-change diffs
Constraint: Permission prompts must mirror CLI behavior closely enough that read-only commands do not get desktop-only prompts
Rejected: Keep rendering Read/Bash bodies inline | too noisy and unlike the intended transcript model
Rejected: Commit only the touched desktop files | would leave the newly introduced desktop app incomplete in git history
Confidence: medium
Scope-risk: broad
Reversibility: messy
Directive: Treat non-writing tools as summary-first transcript events; do not re-expand them by default without validating the UX against long sessions
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test -- --run
Tested: bun test src/server/__tests__/conversations.test.ts
Not-tested: Manual visual regression against the exact screenshots in a live desktop session
Not-tested: Full root TypeScript check (repository still has unrelated extracted-native parse failures)
