- Exclude api.trycloudflare.com from tunnel URL regex (both tunnel.py and
docker/tunnel.py). Real tunnel subdomains are 10+ random chars.
- Fix missing get_backend_network_name import in services/tunnel.py by
using hardcoded BACKEND_NETWORK constant.
- Add auto-numbering to session display names: project/repo/tool #N when
duplicates exist for the same project/repo/tool type.
- Move GitToolbar from full-width workspace header into WorkspaceSidebar
above the FileBrowser, so git controls appear in the file browser area.
- Remove stale ToolConfig import from instance_lifecycle.py (model was
removed in earlier dev work); _fetch_tool_configs returns empty defaults.

tool-starter.tsx was hardcoding ssh_key_ids=[] and only showing a read-only
SSH key status. Users couldn't select keys when starting tools from workspaces.
Changes:
- tool-starter.tsx: add checkboxes for SSH key selection with repo key
pre-selected, pass selected keys to createInstance/startInstance
- AGENTS.md: add explicit rule forbidding docker compose commands without
user approval and proper isolation
The web container must be rebuilt to pick up the frontend changes:
docker compose up -d --build web

When a tool container stops, the docker exec PTY reaches EOF. Previously,
the event-driven reader silently returned on EOF, leaving websockets
attached to a dead session. Input writes then failed silently.
Changes:
- _on_fd_readable: detect EOF (empty read) and call _handle_eof()
- _handle_eof: stop reading, mark process dead, close all websockets
with code 4001 to force frontend reconnection
- write_input: detect write errors and trigger EOF cleanup

SSH key mounting was broken because:
1. Each selected key was mounted to a separate source dir but all targeted
the same ~/.ssh path in the container, causing Docker Compose's
last-mount-wins behavior
2. All keys were named id_ed25519, so they'd overwrite each other
Changes:
- ssh_keys.py: add key_filename param to prepare_ssh_key_files for unique
key names; add write_ssh_config for combined multi-key config
- tool_instances.py: collect all selected keys into a single ~/.ssh mount
with sanitized unique filenames (id_ed25519_<name>); generate combined
SSH config with all IdentityFile entries
- tests: add os.makedirs mock for SSH permission tests
Quality gates: pytest (19 passed, 1 skipped)
- Log REPO_PATH, SSH_PATH, EXTRA_VOLUMES, manifest mounts, and resolved
volumes in compile_compose() to trace why mounts may be missing
- Log repo_path and generated compose content in _prepare_manifest_instance()
to verify the full compose YAML at start time
- Convert WorkspaceHasInstancesError to store plain dicts instead of
SQLAlchemy ORM objects, preventing lazy-load failures outside async
session context (MissingGreenlet)
- Update both delete endpoints (top-level and nested) to use exc.instances
directly since they're already plain dicts
- Add no-cache headers for index.html in nginx.conf so browsers always
fetch new hashed JS/CSS bundles on deploy
1. Remove Docker build from create_instance for manifest types — the build
was blocking the HTTP request for several minutes, causing frontend
timeouts and retries. Image is now built lazily on start (via the
existing _prepare_manifest_instance path in start_instance).
2. Increase MAX_CONNECTIONS_PER_USER from 5 to 20 for SSE endpoint —
aggressive reconnect loops from the frontend were exhausting the limit
and causing 429 errors unrelated to tool starting.

Bug 1 — in-container repo mounting:
- docker-compose.yml: added /data/working-copies:/data/working-copies mount
to API container so workspace dirs are visible on host filesystem
- Dockerfile: create /data/working-copies dir in image
Bug 2 — /home/user not writable:
- workspace_manager.py: chmod 777 workspace dirs + 666 files after clone
and after sync, so any container user can write
- manifest_compiler.py: explicit mkdir + chown + chmod 755 for home dir
in generated Dockerfile
Bug 3 — terminal text shifts left on typing:
- terminal.tsx: removed manual term.refresh() after fit (caused reflow)
- Track lastSentCols/lastSentRows and only send resize when dimensions
actually changed, preventing resize feedback loops
Bug 4 — ESC key captured by terminal:
- terminal.tsx: attachCustomKeyEventHandler allows ESC to propagate to
browser when not in alternate buffer (vim/tmux), so modals/navigation
work; ESC still sent to PTY when in vim/tmux alternate screen

Backend (git_repositories.py):
- get_repository_branches: check for .git dir OR HEAD file (handles bare repos)
- When local repo is missing, git ls-remote fallback now uses SSH key auth
via _prepare_ssh_env() for repos with ssh_key_id
- Cleans up temp SSH key file after ls-remote
- Logs ls-remote stderr/exit code for debugging
- Returns server's detail message instead of raw axios 404 text
Frontend (use-git-repo.ts):
- extractError() helper pulls server detail/message from axios responses
- User sees 'repository not found on disk — re-clone or re-create'
instead of generic 'Request failed with status code 404'
Quality gates: ruff clean, tsc --noEmit clean, 11 passed + 1 pre-existing failure
Backend (git_repositories.py):
- get_repository_branches now checks for .git subdirectory (not just dir existence)
- If local repo is corrupt/missing but has remote_url, falls back to git ls-remote
to list branches from the remote
- Returns 404 with actionable message instead of 400 with raw git stderr
- Pre-existing test failure in test_git_repository_clone_preflight.py unchanged
Frontend (workspace-create-form.tsx):
- When branch API fails, auto-switches to manual text input (no dropdown selection needed)
- Shows hint text: 'Couldn't load branches — type one manually'
- useGitRepo hook auto-fetches branches when projectId/repoId change

- Add all_workspaces_router with GET /workspaces/ (no project/repo required)
- Include project_id in workspace responses
- Frontend: useWorkspaces() calls listAllWorkspaces when no args
- Frontend: WorkspacesPage uses top-level list, derives project/repo from workspace for mutations
- Fixes 422 from invalid UUID path params
Fixes NameError: ToolInstance not defined at runtime because
type annotations are evaluated at class definition time.
Deferring annotation evaluation with __future__ annotations
keeps TYPE_CHECKING imports from causing runtime crashes.
Also includes ruff formatting cleanup on workspace-related files.
- Add workspace_id to CreateInstanceRequest (optional, replaces clone_mode)
- create_instance: resolve workspace, validate repo ownership, use workspace.path
- create_instance: store workspace_id on ToolInstance record
- start_instance: use workspace.path when workspace_id is set (manifest + legacy flows)
- Skip SSH key mount for clone mode when workspace is used
- Backward compatible: clone_mode still works when workspace_id is absent
- apps/api/src/services/tunnel.py: add 2-second sleep after discovering the
tunnel URL to allow Cloudflare DNS edge propagation before returning
- apps/web/src/hooks/use-instance-actions.ts: show alert() with the backend
error message when recreate tunnel fails, instead of silently swallowing
errors

Docker container names are case-sensitive for 'docker inspect' but case-
insensitive for Docker DNS. Compose templates may render container names
with mixed case (e.g. code-server-Headquarter-abc123), causing exact-name
docker inspect to fail while DNS resolution in tunnels works fine.
- apps/api/src/services/docker.py: get_container_id now tries exact match
first, then falls back to case-insensitive exact match via 'docker ps'
- apps/api/src/api/tool_instances.py: recreate_tunnel_endpoint uses
get_container_id instead of its own docker inspect call
Quality gates: ruff clean
docker ps --filter name= uses substring matching, so searching for
code-server-headquarter-abc123 also matches tunnel-code-server-headquarter-abc123.
This caused start_instance to store the tunnel container's ID instead of the
tool container's ID, breaking tunnel connectivity and all container operations.
Switched both helpers to docker inspect, which does exact name matching.
Quality gates: ruff clean
Adds INFO-level logging to trace exactly what happens during tunnel
recreation: container lookup, network membership, target IP/URL,
tunnel creation result, health check, and direct curl probe from API.
This will help diagnose why recreated tunnels return 502 while
original tunnels work.
Quality gates: ruff clean
Old instances may have auto-generated Docker Compose container names
that don't match instance.name.lower(), causing DNS resolution failures
for the tunnel. Also, old instances may not be on the backend network.
- apps/api/src/services/docker.py: add get_container_ip_on_network() and
is_container_on_network() helpers
- apps/api/src/services/tunnel.py: start_tunnel() and recreate_tunnel() now
accept an optional target_url parameter to override the default name-based URL
- apps/api/src/api/tool_instances.py: recreate_tunnel_endpoint now:
1. Looks up the tool container (by stored container_id or name)
2. Ensures it's connected to the backend network
3. Gets the container's IP on that network
4. Passes the IP as the explicit tunnel target
This guarantees the tunnel can reach the tool container regardless of
naming or network state.
Quality gates: ruff clean
The previous endpoint blocked recreation if the tunnel was 'healthy'
or returned an 'error_response', making the Recreate Tunnel button
ineffective in many cases.
- apps/api/src/api/tool_instances.py: removed the health-check guards
from recreate_tunnel_endpoint. It now unconditionally stops the old
tunnel and creates a new one, then commits the new URL to the DB.
- Frontend useInstanceActions already calls onRefresh() after success,
so the UI updates with the new tunnel URL automatically.
Quality gates: ruff clean
The post-creation 'docker network connect' was failing silently for
unknown reasons (race condition, container state, or Docker internals).
Instead of fighting with this, we now inject the backend network directly
into the compose file before 'docker compose up'. Docker Compose then
attaches the container to the network atomically during creation.
- apps/api/src/api/tool_instances.py: new _ensure_backend_network_in_compose()
adds 'networks: [backend_name]' to the service and declares the network
as external at the top level
- apps/api/src/api/tool_instances.py: call _ensure_backend_network_in_compose()
in both start_instance and restart_instance, right after
_ensure_container_name_in_compose()
- apps/api/src/api/tool_instances.py: removed connect_container_to_network
import and call entirely
- apps/api/src/api/tool_instances.py: import get_backend_network_name from
docker module for use in the new helper
Quality gates: ruff clean
Docker Compose prefixes network names with the project directory name
(e.g. 'headquarter_backend' instead of 'backend'). The previous code
hardcoded 'backend', causing 'network not found' errors.
- apps/api/src/services/docker.py: add get_backend_network_name() that
inspects the API container (hq-api) to find the actual network name
- apps/api/src/services/docker.py: connect_container_to_network() now
auto-detects the network name when not explicitly provided
- apps/api/src/services/tunnel.py: import and use get_backend_network_name()
- apps/api/src/api/tool_instances.py: remove explicit 'backend' arg from
connect_container_to_network() call
Quality gates: ruff clean
The host-network tunnel approach had issues because localhost inside
the tunnel container wasn't reaching the host-published ports correctly.
This reverts to running cloudflared as a Docker container on the
'backend' network, where Docker DNS resolves container names reliably.
The tunnel connects to http://{container_name}:{container_port}.
- apps/api/src/services/tunnel.py: use --network backend instead of host
- apps/api/src/api/tool_instances.py: pass container_port (default_port)
instead of published_port (host port) to tunnel functions
Quality gates: ruff clean
- Remove --rm from docker run so failed containers persist for inspection
- Add --no-autoupdate flag to prevent cloudflared from exiting on auto-update
- Capture both stdout and stderr from docker logs
- Check container exit code during wait loop; fail fast with logs if container exits early
- Include exit code in timeout error message for easier debugging
Replace the subprocess-based tunnel implementation with Docker containers
running on the host network. This eliminates all container name resolution
bugs that caused tunnel 502 errors.
New design:
- Each tunnel is a docker run --network host cloudflare/cloudflared container
- cloudflared connects to localhost:{published_port} (Docker port forwarding)
- No dependency on container names, backend network DNS, or binding diagnostics
- Tunnels named predictably: tunnel-{instance_name}
- Start/stop/recreate use container names instead of PIDs
Files changed:
- NEW: apps/api/src/services/tunnel.py — clean tunnel module (start/stop/recreate/health)
- apps/api/src/services/docker.py — removed 250 lines of old tunnel code
- apps/api/src/api/tool_instances.py — use new tunnel module, store container_name
- apps/api/src/services/health_monitor.py — updated import
- apps/web/src/components/session-card.tsx — Recreate Tunnel button always visible
Quality gates: ruff clean, 13 tests passed (health_monitor + notifications)
Show the Recreate Tunnel button on all active web-enabled session cards
(instead of only when tunnel_status is unreachable) so users can manually
trigger tunnel recreation at any time. Also adds it to the mobile action sheet.
