Cursor blinking:
- handleFocus() was referenced in TerminalView template but never
defined in script — clicking the terminal container threw a runtime
error preventing focus. Added the missing function.
- Removed duplicate handleFocus at end of file
Tool windows:
- CSP simplified for macOS WKWebView compatibility. Previous CSP
was blocking child WebviewWindow IPC initialization.
RDP tab switch:
- Added rdp_force_refresh command that marks frame_dirty=true and
clears dirty region, forcing next get_frame to return full buffer
- Called on tab activation and after resize completion
- Eliminates 4-5 second wait for "keyframe" when switching tabs

When the Wraith window is resized, the RDP session now resizes to fill
the entire canvas area — matching MobaXTerm behavior.
Implementation:
- Enabled ironrdp displaycontrol feature for Display Control Virtual Channel
- Added Resize input event to RDP session thread
- ActiveStage::encode_resize() sends monitor layout PDU to server
- Server re-renders at new resolution and sends updated frames
- Frontend ResizeObserver on canvas wrapper, debounced 500ms
- Canvas CSS changed from max-width/max-height to width/height: 100%
- Mouse coordinate mapping uses canvas.width/height (actual resolution)
instead of initial rdpWidth/rdpHeight
- Image and front buffer reallocated on resize to match new dimensions
- Width constrained to even numbers per RDP spec, min 200px

Root cause: Every GraphicsUpdate copied the full 8.3MB decoded image
into the front buffer, cloned all 8.3MB for IPC, and transferred all
8.3MB to the frontend — even when only a 100x100 pixel region changed.
During window drag, this created a 25MB/frame pipeline backup.
Fix:
- Track dirty rectangles from ironrdp's GraphicsUpdate(InclusiveRectangle)
- Write path: only copy changed rows from decoded image to front buffer
(e.g. 100 rows × 1920 pixels = 768KB vs 8.3MB full frame)
- Accumulate dirty region as union of all rects since last get_frame
- Read path: if dirty region < 50% of frame, extract only the dirty
rectangle bytes; otherwise fall back to full frame
- Binary IPC format: 8-byte header [x,y,w,h as u16 LE] + pixel data
- Frontend: putImageData at dirty rect offset instead of full frame
- Status bar: h-9 text-sm for 3440x1440 readability
During window drag (typical 300x400 dirty rect):
Before: 8.3MB write + 8.3MB clone + 8.3MB IPC = 24.9MB per frame
After: 480KB write + 480KB extract + 480KB IPC = 1.4MB per frame
~17x reduction in data movement per frame.

Root cause: RDP was unresponsive due to frame pipeline bottleneck.
- get_frame() held tokio::Mutex while cloning 8.3MB, blocking the
RDP session thread from writing new frames (mutex contention)
- Frontend fetched on every backend event with no coalescing
- Every GraphicsUpdate emitted an IPC event, flooding the frontend
Fix:
- Double-buffer: back_buffer (tokio::Mutex, write path) and
front_buffer (std::sync::RwLock, read path) — reads never block writes
- get_frame() now synchronous, reads from front_buffer via RwLock
- Backend throttles frame events to every other GraphicsUpdate
- Frontend coalesces events via requestAnimationFrame
- RdpView props now reactive (computed) for correct resize behavior
- rdp_get_frame command no longer async (no .await needed)
- screenshot_png_base64 no longer async

- percent_decode: collect bytes into Vec<u8> then String::from_utf8_lossy to handle
non-ASCII paths correctly instead of casting byte as char (corrupted codepoints > 127)
- format_mtime: remove dead `st`/`y`/`_y` variables and unused UNIX_EPOCH/Duration imports
- reorder_connections/reorder_groups: wrap UPDATE loops in BEGIN/COMMIT transactions
with ROLLBACK on error to prevent partial sort order writes
- scan_network: validate subnet matches 3-octet format before use in remote shell commands

- New shell_escape() utility for safe command interpolation
- Applied across all MCP tools, docker, scanner, network commands
- MCP server generates random bearer token at startup
- Token written to mcp-token file with 0600 permissions
- All MCP HTTP requests require Authorization header
- Bridge binary reads token and sends on every request

- Vault key uses Zeroizing<[u8; 32]>, passwords zeroized after use
- vault/credentials Mutex upgraded to tokio::sync::Mutex
- CWD tracker + monitor use CancellationToken for clean shutdown
- Monitor exec_command has 10s timeout, 3-strike dead connection heuristic

Was only setting the remote clipboard without pasting. Now sends
clipboard content then simulates Ctrl+V (scancode 0x001D + 0x002F)
with 50ms delay for clipboard propagation. Works for any text

The AI can now open its own SSH sessions without the Commander
pre-opening them:
- ssh_connect(hostname, username, password?, private_key_path?, port?)
Returns session_id for use with all other tools
Supports password auth and SSH key file auth
Also added app_handle and error_watcher to MCP server state so
new sessions get full scrollback, monitoring, and CWD tracking.
This completes the autonomy loop: the AI discovers what's available
(list_sessions), connects to what it needs (ssh_connect), operates
(terminal_execute, docker_ps, sftp_read), and disconnects when done.
Total MCP tools: 31.

3 new MCP tools completing the RDP interaction loop:
- rdp_click — click at x,y coordinates (left/right/middle button)
Use terminal_screenshot first to identify coordinates
- rdp_type — type text into RDP session via clipboard paste
- rdp_clipboard — set clipboard content on remote desktop
The AI can now screenshot an RDP session, analyze it visually,
click buttons, type text, and read clipboard content. Full GUI
automation through the MCP bridge.
Total MCP tools: 30.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
8 new MCP tools exposed through the bridge:
Docker:
- docker_ps — list all containers with status/image/ports
- docker_action — start/stop/restart/remove/logs/builder-prune/system-prune
- docker_exec — execute command inside a running container
System:
- service_status — check systemd service status
- process_list — ps aux with optional name filter
Git (remote repos):
- git_status — branch, dirty files, ahead/behind
- git_pull — pull latest changes
- git_log — recent 20 commits
Total MCP tools: 27. All accessible through the wraith-mcp-bridge.

RDP performance overhaul:
- Switched from polling (rAF loop calling rdp_get_frame every tick)
to event-driven rendering (backend emits rdp:frame:{id} when
frame buffer updates, frontend fetches on demand)
- Eliminates thousands of empty IPC round-trips per second when
the screen is idle
- Backend passes AppHandle into run_active_session for event emission
- Frontend uses listen() instead of requestAnimationFrame polling
MCP terminal fix:
- terminal_type and terminal_execute now send \r (carriage return)
instead of \n (newline) — PTY terminals expect CR to submit
- Fixes commands not auto-sending, requiring manual Enter press
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
terminal_type MCP tool (19 tools total):
- Fire-and-forget text input to any session
- Optional press_enter flag (default: true)
- No marker wrapping, no output capture
- Use case: AI sends messages/commands without needing output back
Tab resize fix:
- Double requestAnimationFrame before fitAddon.fit() on tab switch
- Container has real dimensions after browser layout pass
- Also sends ssh_resize/pty_resize to backend with correct cols/rows
- Fixes 6-8 char wide terminals after switching tabs
Close confirmation:
- beforeunload event shows browser "Leave page?" dialog
- Only triggers if sessions are active
- Synchronous — cannot hang the close like onCloseRequested did

DashMap::clone() deep-copies all entries into a new map. The MCP
server's cloned SshService/SftpService/RdpService/ScrollbackRegistry
were snapshots from startup that never saw new sessions.
Fix: wrap all DashMap fields in Arc<DashMap<...>> so clones share
the same underlying map. Sessions added after MCP startup are now
visible to MCP tools.
Affected: SshService, SftpService, RdpService, ScrollbackRegistry.

On startup, Wraith checks if wraith-mcp-bridge exists in the data
directory. If missing or version mismatch, downloads the correct
version from Gitea packages automatically. No installer changes needed.
Flow:
1. Check data_dir/wraith-mcp-bridge.exe exists
2. Check data_dir/mcp-bridge-version matches app version
3. If not, download from packages/vstockwell/generic/wraith/{ver}/
4. Set execute permissions on Unix
5. Write version marker
Also exposes mcp_bridge_path command so the frontend can show the
path in settings for users to add to PATH or configure Claude Code.

- Removed useless CLAUDE_MCP_SERVERS env var injection (doesn't work)
- CI builds wraith-mcp-bridge.exe as a separate cargo --bin step
- Bridge binary signed with EV cert alongside the installer
- Uploaded to Gitea packages per version
- Attached to Gitea release as a downloadable asset
- Users add to PATH then: claude mcp add wraith -- wraith-mcp-bridge

Tauri auto-updater:
- Signing pubkey in tauri.conf.json
- tauri-plugin-updater initialized in lib.rs
- CI workflow passes TAURI_SIGNING_PRIVATE_KEY env vars to cargo tauri build
- CI generates update.json manifest with signature and uploads to
packages/latest/update.json endpoint
- Frontend checks for updates on startup via @tauri-apps/plugin-updater
- Downloads, installs, and relaunches seamlessly
- Settings → About button uses native updater too
RDP vault credentials:
- RDP connections now resolve credentials from vault via credentialId
- Same path as SSH: list_credentials → find by ID → decrypt_password
- Falls back to conn.options JSON if no vault credential linked
- Fixes blank username in RDP connect
Sidebar drag persist:
- reorder_connections and reorder_groups Tauri commands
- Batch-update sort_order in database on drop
- Order survives app restart

Same root cause as the PTY crash (v1.2.6): tokio::spawn called from
Tauri setup hook without a tokio runtime guard. Switched error watcher
to std:🧵:spawn. Also wrapped both error watcher and MCP server
spawn in individual catch_unwind blocks so neither can crash the app.

MCP: RdpService had a manual Clone impl that called unreachable!().
Replaced with a real clone that shares the DashMap. MCP server can
now clone all services and start successfully.
RDP: rustls needs CryptoProvider::install_default() before any TLS
operations. ironrdp-tls uses rustls for the RDP TLS handshake.
Added aws_lc_rs provider installation at app startup.
Both panics found via wraith.log debug logging from v1.6.3.

Debug logging:
- wraith_log!() macro available in all modules, writes to wraith.log
- SSH connect/auth, PTY spawn, RDP connect all log with session IDs
- MCP startup panic now shows the actual error message
Copilot "Tools" button:
- Shows when a PTY session is active in the copilot panel
- Injects a formatted list of all 18 MCP tools into the chat
- Groups tools by category: session, terminal, SFTP, network, utilities
- Includes parameter signatures so the AI knows how to call them

Was logging "panicked — continuing" without the WHY. Now captures
the panic payload (String, &str, or type_id) so the log shows
exactly what went wrong in clone_services().

RDP: wrapped connection thread in catch_unwind so panics are logged
to wraith.log instead of silently killing the channel. Error message
now directs user to check the log.
CWD: changed cd . to cd ~ after OSC 7 hook injection so SFTP starts
at the user's home directory on macOS (where / requires explicit nav).

The printf argument had escaped quotes that passed through literally,
producing paths like /"/Users/foo". Removed the outer escaped quotes

Checks Gitea releases API for latest version on startup. If newer
version available, shows confirm dialog to open download page.
Also adds "Check for Updates" button in Settings → About with
version comparison, release notes display, and download button.

Switched to printf '\e]7;file://localhost/%s\a' with sed space encoding.
BEL (\a) terminator is more universally supported than ST (\e\\).

The CWD hook command was visible to the user. Now wrapped in
stty -echo/echo to suppress echo, followed by clear to wipe the
screen. Space prefix prevents history recording in most shells.

env_logger was never initialized so log::info/error went nowhere.
Added write_log() that appends to data_dir/wraith.log with timestamps.

SFTP tab switch fix:
- Removed :key on FileTree that destroyed component on every switch
- useSftp now accepts a reactive Ref<string> sessionId
- Watches sessionId changes and reinitializes without destroying state
- Per-session path memory via sessionPaths map — switching back to a
tab restores exactly where you were browsing
CWD following fix (macOS + all platforms):
- Injects OSC 7 prompt hook into the shell after SSH connect
- zsh: precmd() emits \e]7;file://host/path\e\\
- bash: PROMPT_COMMAND emits the same sequence
- Sent via the PTY channel so it configures the interactive shell
- The passive OSC 7 parser in the output loop picks it up
- SFTP sidebar auto-navigates to the current working directory

The + button in the tab bar now shows a dropdown of detected local
shells. Clicking one opens a full-size PTY terminal in the main
content area as a proper tab — not the copilot sidebar.
- New "local" protocol type in Session interface
- LocalTerminalView component uses useTerminal(id, 'pty')
- SessionContainer renders local sessions alongside SSH/RDP
