"""Real-Supervisor parallel of ``test_supervisor_mock.py`` for the inaddon tier.

This module mirrors the test classes from ``test_supervisor_mock.py`` but
runs against the real Supervisor process inside the HAOS-inaddon CI tier
(see #1349 item 6). The mock module stays put as the ``external_only``
coverage path (testcontainer + external-HAOS); this module covers the
same Supervisor wire contract against the real Supervisor that ships
inside HAOS, with assertions adapted for live responses
(shape-not-content).

**Two tests are intentionally NOT migrated** from ``test_supervisor_mock.py``:

* ``TestBugReportAddonLogs::test_returns_empty_when_token_missing`` — verifies
  the in-process ``_fetch_addon_logs()`` defensive guard returns an empty
  string when ``SUPERVISOR_TOKEN`` is unset. In inaddon mode the test
  process is the harness, but the function reads ``SUPERVISOR_TOKEN``
  inside the addon container's own process (where it IS set). We cannot
  ``monkeypatch.delenv`` the addon-process env without restarting the
  addon. Coverage stays in the mock-tier (external_only) suite.
* ``TestMockResilience::test_unauthorized_supervisor_call_surfaces_as_tool_error`` —
  same family of problem. Forcing a bad ``SUPERVISOR_TOKEN`` requires
  mutating the addon container's env, which would either need test-only
  env overrides in production code (rejected) or an addon restart cycle
  per assertion. The 401 wire-contract coverage stays in the mock-tier
  suite; this module covers the 403 path against a real
  insufficient-role token (the SSH addon's ``hassio_role: default``).

See ``docs/superpowers/specs/2026-05-18-1349-closeout-design.md`` — the
"Token-missing + bad-token paths" section under spec-review fixes for
the design rationale.

# NOTE on inaddon coverage scope:
#
# The inaddon tier reaches the MCP tool code via ``mcp_client`` — the test
# process is on the CI host but the tool runs INSIDE the addon, where
# ``SUPERVISOR_TOKEN`` is set by Supervisor. So any helper that the test
# runner can reach THROUGH a public MCP tool can be exercised against the
# real Supervisor; ``TestBugReportAddonLogsReal`` below uses
# ``ha_report_issue`` to do exactly that for ``_fetch_addon_logs()``.
#
# A few mock-tier surfaces remain mock-only on purpose:
#
# - ``TestBugReportAddonLogs::test_returns_empty_when_token_missing`` and
#   ``TestFixtureWiring::*`` — verify defensive behavior when SUPERVISOR_TOKEN
#   is unset or the runtime helpers see an addon-less env. On inaddon the
#   addon process always has the token set; we can't ``monkeypatch.delenv``
#   the addon-process env without restarting the addon, so the missing-token
#   branch can only be exercised on the mock tier.
# - ``TestSettingsUiRestart::test_restart_request_succeeds`` — POSTing to
#   ``/api/settings/restart`` actually restarts the addon and kills
#   ``mcp_client`` for every subsequent test. ``TestSettingsUiRestartReal``
#   below uses the ``slug`` parameter against the SSH addon instead so the
#   real wire contract gets exercised without taking the test session down.
# - ``TestSettingsUiRestart::test_restart_request_rejects_bad_token`` — the
#   401 path requires injecting a wrong ``SUPERVISOR_TOKEN`` into the addon
#   process, which means restarting the addon with a corrupted env. Same
#   destructive blocker as above; stays mock-only.
