Turn on the PTH rule set in ruff and convert the remaining call sites
that triggered violations:
- `supervisor/utils/yaml.py` and `tests/homeassistant/test_module.py`
use `Path.open()` instead of the builtin `open()`.
- `tests/backups/test_backup.py` and
`tests/resolution/fixup/test_store_execute_reset.py` use
`Path.iterdir()` instead of `os.listdir()`.
- `tests/mounts/test_mount.py` uses `Path.unlink()` instead of
`os.remove()`.
- `tests/store/test_translation_load.py` uses `Path.mkdir(parents=True)`
instead of `os.makedirs()`.
- `tests/hardware/test_disk.py` captures the unpatched `Path.is_dir`,
`Path.is_symlink` and `Path.stat` before the `patch.object(Path, ...)`
block so the mocks can delegate to the real implementations without
reaching for `os.path.isdir`/`os.path.islink`/`os.stat`.
* Use Unix socket for Supervisor to Core communication
Reintroduce Unix socket support for Supervisor-to-Core communication
(reverted in #6735) with the addition of a feature flag gate. The
feature is now controlled by the `core_unix_socket` feature flag and
disabled by default.
When enabled and Core version supports it, Supervisor communicates with
Core via a Unix socket at /run/os/core.sock instead of TCP. This
eliminates the need for access token authentication on the socket path,
as Core authenticates the peer by the socket connection itself.
Key changes:
- Add FeatureFlag.CORE_UNIX_SOCKET to gate the feature
- HomeAssistantAPI: transport-aware session/url/websocket management
- WSClient: separate connect() (Unix, no auth) and connect_with_auth()
(TCP) class methods with proper error handling
- APIProxy delegates websocket setup to api.connect_websocket()
- Container state tracking for Unix session lifecycle
- CI builder mounts /run/supervisor for integration tests

* Sort feature flags alphabetically
* Drop per-call max_msg_size from WSClient
Hardcode the WebSocket message size cap to 64 MB in WSClient and remove
the parameter from WSClient.connect, connect_with_auth, _ws_connect,
and HomeAssistantAPI.connect_websocket. This was only ever overridden
by APIProxy, so threading it through four layers was unnecessary.
max_msg_size is a cap, not a pre-allocation; aiohttp only grows buffers
to the size of actual incoming messages. Supervisor's own control
channel never approaches 64 MB, so unifying the limit has no runtime
cost.
Addresses review feedback on #6742.

* Use Unix socket for Supervisor to Core communication
Switch internal Supervisor-to-Core HTTP and WebSocket communication
from TCP (port 8123) to a Unix domain socket.
The existing /run/supervisor directory on the host (already mounted
at /run/os inside the Supervisor container) is bind-mounted into the
Core container at /run/supervisor. Core receives the socket path via
the SUPERVISOR_CORE_API_SOCKET environment variable, creates the
socket there, and Supervisor connects to it via aiohttp.UnixConnector
at /run/os/core.sock.
Since the Unix socket is only reachable by processes on the same host,
requests arriving over it are implicitly trusted and authenticated as
the existing Supervisor system user. This removes the token round-trip
where Supervisor had to obtain and send Bearer tokens on every Core
API call. WebSocket connections are likewise authenticated implicitly,
skipping the auth_required/auth handshake.
Key design decisions:
- Version-gated by CORE_UNIX_SOCKET_MIN_VERSION so older Core
versions transparently continue using TCP with token auth
- LANDINGPAGE is explicitly excluded (not a CalVer version)
- Hard-fails with a clear error if the socket file is unexpectedly
missing when Unix socket communication is expected
- WSClient.connect() for Unix socket (no auth) and
WSClient.connect_with_auth() for TCP (token auth) separate the
two connection modes cleanly
- Token refresh always uses the TCP websession since it is inherently
a TCP/Bearer-auth operation
- Logs which transport (Unix socket vs TCP) is being used on first
request

* Close WebSocket on handshake failure and validate auth_required
Ensure the underlying WebSocket connection is closed before raising
when the handshake produces an unexpected message. Also validate that
the first TCP message is auth_required before sending credentials.

* Check running container env before using Unix socket
Split use_unix_socket into two properties to handle the Supervisor
upgrade transition where Core is still running with a container
started by the old Supervisor (without SUPERVISOR_CORE_API_SOCKET):
- supports_unix_socket: version check only, used when creating the
Core container to decide whether to set the env var
- use_unix_socket: version check + running container env check, used
for communication decisions
This ensures TCP fallback during the upgrade transition while still
hard-failing if the socket is missing after Supervisor configured
Core to use it.

* Improve Core API communication logging and error handling
- Remove transport log from make_request that logged before Core
container was attached, causing misleading connection logs
- Log "Connected to Core via ..." once on first successful API response
in get_api_state, when the transport is actually known
- Remove explicit socket existence check from session property, let
aiohttp UnixConnector produce natural connection errors during
Core startup (same as TCP connection refused)
- Add validation in get_core_state matching get_config pattern
- Restore make_request docstring

* Guard Core API requests with container running check
Add is_running() check to make_request and connect_websocket so no
HTTP or WebSocket connection is attempted when the Core container is
not running. This avoids misleading connection attempts during
Supervisor startup before Core is ready.
Also make use_unix_socket raise if container metadata is not available
instead of silently falling back to TCP. This is a defensive check
since is_running() guards should prevent reaching this state.
Add attached property to DockerInterface to expose whether container
metadata has been loaded.

* Reset Core API connection state on container stop
Listen for Core container STOPPED/FAILED events to reset the
connection state: clear the _core_connected flag so the transport
is logged again on next successful connection, and close any stale
Unix socket session.

* Only mount /run/supervisor if we use it
* Fix pytest errors
* Remove redundant is_running check from ingress panel update
The is_running() guard in update_hass_panel is now redundant since
make_request checks is_running() internally. Also mock is_running
in the websession test fixture since tests using it need make_request
to proceed past the container running check.

* Bind mount /run/supervisor to Supervisor /run/os
Home Assistant OS (as well as the Supervised run scripts) bind mount
/run/supervisor to /run/os in Supervisor. Since we reuse this location
for the communication socket between Supervisor and Core, we need to
also bind mount /run/supervisor to Supervisor /run/os in CI.
* Wrap WebSocket handshake errors in HomeAssistantAPIError
Unexpected exceptions during the WebSocket handshake (KeyError,
ValueError, TypeError from malformed messages) are now wrapped in
HomeAssistantAPIError inside WSClient.connect/connect_with_auth.
This means callers only need to catch HomeAssistantAPIError.
Remove the now-unnecessary except (RuntimeError, ValueError,
TypeError) from proxy _websocket_client and add a proper error
message to the APIError per review feedback.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Narrow WebSocket handshake exception handling
Replace broad `except Exception` with specific exception types that
can actually occur during the WebSocket handshake: KeyError (missing
dict keys), ValueError (bad JSON), TypeError (non-text WS message),
aiohttp.ClientError (connection errors), and TimeoutError. This
avoids silently wrapping programming errors into HomeAssistantAPIError.

* Remove unused create_mountpoint from MountBindOptions
The field was added but never used. The /run/supervisor host path
is guaranteed to exist since HAOS creates it for the Supervisor
container mount, so auto-creating the mountpoint is unnecessary.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Clear stale access token before raising on final retry
Move token clear before the attempt check in connect_websocket so
the stale token is always discarded, even when raising on the final
attempt. Without this, the next call would reuse the cached bad token
via _ensure_access_token's fast path, wasting a round-trip.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Add tests for Unix socket communication and Core API
Add tests for the new Unix socket communication path and improve
existing test coverage:
- Version-based supports_unix_socket and env-based use_unix_socket
- api_url/ws_url transport selection
- Connection lifecycle: connected log after restart, ignoring
unrelated container events
- get_api_state/check_api_state parameterized across versions,
responses, and error cases
- make_request is_running guard and TCP flow with real token fetch
- connect_websocket for both Unix and TCP (with token verification)
- WSClient.connect/connect_with_auth handshake success, errors,
cleanup on failure, and close with pending futures
Consolidate existing tests into parameterized form and drop synthetic
tests that covered very little.

* Unify Core user listing with HomeAssistantUser model
Replace the ingress-specific IngressSessionDataUser with a general
HomeAssistantUser dataclass that models the Core config/auth/list WS
response. This deduplicates the WS call (previously in both auth.py
and module.py) into a single HomeAssistant.list_users() method.
- Add HomeAssistantUser dataclass with fields matching Core's user API
- Remove get_users() and its unnecessary 5-minute Job throttle
- Auth and ingress consumers both use HomeAssistant.list_users()
- Auth API endpoint uses typed attribute access instead of dict keys
- Migrate session serialization from legacy "displayname" to "name"
- Accept both keys in schema/deserialization for backwards compat
- Add test for loading persisted sessions with legacy displayname key

* Tighten list_users() to trust Core's auth/list contract
Core's config/auth/list WS command always returns a list, never None.
Replace the silent `if not raw: return []` (which also swallowed empty
lists) with an assert, remove the dead AuthListUsersNoneResponseError
exception class, and document the HomeAssistantWSError contract in the
docstring.

* Remove | None from async_send_command return type
The WebSocket result is always set from data["result"] in _receive_json,
never explicitly to None. Remove the misleading | None from the return
type of both WSClient and HomeAssistantWebSocket async_send_command, and
drop the now-unnecessary assert in list_users.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Use HomeAssistantWSConnectionError in _ensure_connected
_ensure_connected and connect_with_auth raise on connection-level
failures, so use the more specific HomeAssistantWSConnectionError
instead of the broad HomeAssistantWSError. This allows callers to
distinguish connection errors from Core API errors (e.g. unsuccessful
WebSocket command responses). Also document that _ensure_connected can
propagate HomeAssistantAuthError from ensure_access_token.

* Remove user list cache from _find_user_by_id
Drop the _list_of_users cache to avoid stale auth data in ingress
session creation. The method now fetches users fresh each time and
returns None on any API error instead of serving potentially outdated
cached results.

* Raise HomeAssistantWSError when Core WebSocket is unreachable
Previously, async_send_command silently returned None when Home Assistant
Core was not reachable, leading to misleading error messages downstream
(e.g. "returned invalid response of None instead of a list of users").
Refactor _can_send to _ensure_connected which now raises
HomeAssistantWSError on connection failures while still returning False
for silent-skip cases (shutdown, unsupported version). async_send_message
catches the exception to preserve fire-and-forget behavior.
Update callers that don't handle HomeAssistantWSError: _hardware_events
and addon auto-update in tasks.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Simplify HomeAssistantWebSocket command/message distinction
The WebSocket layer had a confusing split between "messages" (fire-and-forget)
and "commands" (request/response) that didn't reflect Home Assistant Core's
architecture where everything is just a WS command.
- Remove dead WSClient.async_send_message (never called)
- Rename async_send_message → _async_send_command (private, fire-and-forget)
- Rename send_message → send_command (sync wrapper)
- Simplify _ensure_connected: drop message param, always raise on failure
- Simplify async_send_command: always raise on connection errors
- Remove MIN_VERSION gating (minimum supported Core is now 2024.2+)
- Remove begin_backup/end_backup version guards for Core < 2022.1.0
- Add debug logging for silently ignored connection errors

* Wait for Core to come up before backup
This is crucial since the WebSocket command to Core now fails with the
new error handling if Core is not running yet.
* Wait for Core install job instead
* Use CLI to fetch jobs instead of Supervisor API
The Supervisor API needs authentication token, which we have not
available at this point in the workflow. Instead of fetching the token,
we can use the CLI, which is available in the container.
