- Add full mobile viewport CSS: overflow-y scroll, -webkit-overflow-scrolling
touch, overscroll-behavior-y contain, translate3d hardware accel,
scroll-behavior smooth, touch-action pan-y
- After term.open(), find .xterm-viewport and add passive touch listeners
that call stopPropagation() (not preventDefault) — this lets the browser
handle native touch scrolling while preventing xterm.js internal handlers
from interfering
- Based on xterm.js known issue #5489 and SCROLLING_FIX.md approach
- xterm.js has zero touch event handlers (verified: only 1 'touch' ref in
entire library), so it wasn't intercepting anything
- Our touch-action: none + preventDefault() combo was blocking the browser
from scrolling the .xterm-viewport natively
- Removed all custom touch event handlers from terminal.tsx
- Removed touch-action: none from .terminal-container
- Added touch-action: pan-y to .xterm-viewport so browser allows vertical pan
- Body scroll lock (terminal-page-open) prevents page from scrolling
- Attach touch listeners to document with capture:true instead of container
- Check if touch target is inside terminal container before handling
- This runs before xterm.js internal handlers, giving us full control
- Add touch-action: none to terminal container to prevent browser gestures
- Lower threshold to 3px, 20px per line for responsive scrolling
- Add body.terminal-page-open { overflow: hidden } to prevent page scroll
- TerminalPage adds/removes 'terminal-page-open' class on body when mounted
- Re-add capture-phase touch listeners in terminal.tsx with low 3px threshold
- Call e.preventDefault() immediately when vertical gesture is detected,
before browser compositor commits to page scroll
- Remove CSS touch-action overrides on xterm viewport (now handled in JS)
- Scroll forwarded via term.scrollLines() with 24px per line sensitivity
- Remove all custom touch event interception code from terminal.tsx
- After term.open(), find the internal .xterm-viewport element and set
touchAction=pan-y and overscrollBehavior=contain via inline styles
- Add CSS targeting .xterm-viewport on mobile with touch-action: pan-y,
-webkit-overflow-scrolling: touch, and overflow-y: auto
- Let the browser handle vertical touch panning natively instead of
trying to intercept and manually forward events
- Attach touch listeners to container wrapper in CAPTURE phase so they run
before xterm.js internals stop propagation
- Add e.stopPropagation() in touchmove after handling scroll to prevent
xterm.js from conflicting with our scroll
- Add wheel event fallback for mobile browsers that synthesize wheel from touch
- Remove touch-action: none CSS which was blocking native xterm viewport scroll
- Attach touch listeners to term.element (xterm root) instead of wrapper
- Fix scroll direction: swipe up now scrolls up (shows older buffer)
- Remove RAF indirection; scroll applied synchronously in touchmove
- Accumulate delta between events for smoother scrolling
- Lower threshold to 6px and px-per-line to 16 for better responsiveness
- Add touch-action: none to terminal container on mobile
- Intercepts touch events on the terminal container when isMobile=true
- Detects vertical swipe gestures (dominant over horizontal movement)
- Translates swipe distance to xterm.js scrollLines() calls
- Uses requestAnimationFrame for smooth scroll updates
- Threshold of 10px before scroll kicks in; 30px per line
- Touch listeners cleaned up on component unmount
Root cause: _ensure_web_bind_address injected --host 0.0.0.0 for code-server,
which only sets the bind host, not the port. code-server then listens on its
default port (8080) instead of the tool type's default_port (8443). Cloudflared
connects to port 8443 and gets connection refused, resulting in a 502.
Changes:
- _ensure_web_bind_address now accepts default_port and builds
--bind-addr 0.0.0.0:{port} for code-server
- Same fix for jupyter-notebook with explicit --port flag
- Existing broken --host commands are now detected and replaced
- New migration fixes tool_types templates and instance compose files on disk
- Test fixture updated to use correct --bind-addr 0.0.0.0:8443
- Inject explicit container_name into compose files at start/restart time
via _ensure_container_name_in_compose() to prevent Docker Compose from
generating UUID-based auto names that break backend network resolution.
- Use instance.name.lower() directly instead of get_container_name() lookups
which were unreliable with auto-generated names.
- Apply compose sanitization, bind-address fix, and container-name injection
on restart_instance as well so restarts pick up template fixes.
- Add --force-recreate to docker compose up to ensure container_name changes
take effect immediately.
- Fix notification lifecycle tests to match current behavior (success severity,
health_changed event for ownership test).
Quality gates: ruff clean, pytest (7 notification lifecycle tests passed)
- Uses navigator.wakeLock.request('screen') to keep device awake
- Re-acquires wake lock when tab becomes visible again
- Releases wake lock on component unmount
- Silently ignored on unsupported browsers or if denied
- Add SpecialKeysStrip and SpecialKeysPanel to mobile terminal page
- Store sendData and focusInput refs via onTerminalReady callback
- Pass activeModifier/onModifierChange to TerminalComponent on mobile
- Add virtual keyboard padding to prevent keyboard from covering terminal
- Special keys bar sits at bottom of viewport, panel opens as overlay
- Replace inline header+tabs layout with position:absolute overlay
- Overlay contains: back button, session name, status dot, A-/A+ font size, exit
- Session tabs live inside the overlay below the toolbar
- Auto-hides after 3s; clicking terminal content hides it immediately
- Pull handle at top edge appears when overlay is hidden to restore it
- Terminal content always fills full viewport; overlay never resizes container
- Pass showControls=false to TerminalComponent on mobile to avoid double headers
Problem: linuxserver/code-server already binds to 0.0.0.0 by default.
Adding any command: override (--bind-addr or --host) breaks the LSIO
s6 init system with 'not found' errors.
Changes:
- _ensure_web_bind_address(): Skip LSIO images entirely (no command
override needed). If an existing override is found, remove it.
- New migration 2026_05_29_remove_lsio_command_override: Removes
--bind-addr and --host command overrides from both DB templates
and existing instance compose files on disk for LSIO images.
- Fixed migration to use correct column name (compose_path) and
check information_schema for column existence defensively.

Problem: The first migration already ran on the user's server with
--bind-addr (broken). Alembic won't re-run the fixed migration.
Changes:
- _ensure_web_bind_address(): Now detects existing --bind-addr commands
and replaces them with --host 0.0.0.0 instead of skipping
- New migration 2026_05_29_fix_code_server_bind_addr: Finds code-server
tool types with --bind-addr in compose_template and replaces with
--host 0.0.0.0

FastAPI matches routes in declaration order. The DELETE /notifications
endpoint (bulk clear) was registered AFTER DELETE /notifications/{id},
so the path parameter route intercepted all requests to the bulk route,
causing a 422 UUID validation error instead of hitting clear_all.
Moved clear_all_notifications above dismiss_notification in the router.
Added regression test to verify route order.

Frontend was sending empty string for config_profile_id when no profile
was selected, causing 'not compatible' validation error. Backend now
treats any falsy value (None, empty string) as 'no profile selected'.
Notification filtering:
- lifecycle_hooks.py: only instance.error and instance.health_changed
with status=running generate notifications. All other lifecycle events
(created, started, stopped, restarted, deleted) are filtered out.
- health_monitor.py: only error and unhealthy states generate notifications.
Running/recovered state no longer creates info notifications.
- _derive_title now maps instance.health_changed to "Container ready".
Clear-all button:
- Added dismiss_all() to NotificationService
- Added DELETE /notifications endpoint for bulk dismiss
- Frontend: clearAllNotifications API, clearAll in notification context,
"Clear all" button in notification drawer alongside "Mark all as read"
- Added CSS for .notification-clear-all with danger hover state
- Updated notification-center tests

The --bind-addr flag caused code-server to fail entirely (app not
responding on any interface). The correct override for the
coder/code-server image is --host 0.0.0.0, which overrides the
entrypoint's --host 127.0.0.1.
Changes:
- Migration: Replace --bind-addr with --host 0.0.0.0, also handle
existing broken templates by detecting --bind-addr and replacing it
- Runtime safety net: _ensure_web_bind_address uses --host 0.0.0.0
- Test fixture: Updated compose template to match
Quality gates: pytest 42 passed
Root cause: code-server (and similar web tools) default to binding to
127.0.0.1 (localhost) inside their containers. This makes them unreachable
from the Docker network and from cloudflared, which connects via the
container's Docker network name.
Changes:
- Migration: Update code-server compose_template to include
--bind-addr 0.0.0.0:8443 command override
- Migration: Update jupyter-notebook compose_template to include
--ip=0.0.0.0 flag
- Runtime safety net: _ensure_web_bind_address() auto-injects bind
address for known web tools (code-server, jupyter-notebook) when
compose doesn't already specify a command
- Diagnostics: _check_app_binding() compares internal vs external
connectivity to detect 127.0.0.1 binding issues
- Improved readiness check: 30s timeout, checks HTTP status codes,
logs curl stderr for debugging

The create-session-form was calling startInstance() without passing the
selected config profile and SSH keys. This caused the backend to receive
ssh_key_ids=[] and clear the keys that were stored during createInstance.
The .ssh directory was never mounted because instance.ssh_key_ids was
wiped during the start call.
Also includes minor formatting cleanup on the data migration.
Quality gates: pytest (18 passed)
- Add _check_app_binding() to detect if app is bound to 127.0.0.1
instead of 0.0.0.0 (common cause of tunnel 'app error 0')
- Improve curl readiness check: wait up to 30s, check HTTP status codes
(accept 2xx, 3xx, 401, 403 as 'ready')
- Log curl stderr for connection debugging
- Log binding diagnosis when external connectivity fails

The API container and tool instances share the 'backend' Docker network
(connect_container_to_network at tool_instances.py:1576). cloudflared
runs INSIDE the api container, so localhost:host_port is unreachable.
The original container_name:internal_port is correct for networking.
The 'app error 0' is an application-level issue, not networking.
This reverts commit a8fbca9.
The ssh_keys mount was already removed from the Alembic seed migration, but
that migration had already been applied to the DB. This data migration
removes the mount from the actual tool_definition_manifests row so that
instance-level SSH key mounting handles keys exclusively.
Quality gates: pytest (18 passed)
- apply_mount_permissions now skips mounts with readonly=true to avoid
'Read-only file system' warnings on post-start chown/chmod
- Removed the ssh_keys mount from the pi-agent manifest definition;
instance-level SSH key mounting now handles this exclusively
- Added unit test for read-only mount skipping

Root cause: start_cloudflared_tunnel was trying to connect to
http://{container_name}:{container_port}, but:
1. The host OS cannot resolve Docker container names
2. cloudflared runs on the host, so it needs the host-mapped port
Changes:
- start_cloudflared_tunnel: changed signature to accept host_port only
- Connects cloudflared to localhost:{host_port} via Docker port mapping
- Connectivity check uses localhost:{host_port}
- recreate_tunnel updated to match new signature
- Callers in tool_instances.py pass instance.port (host port)
