fix(tests): add conftest.py + fix test_call_peer_errors.py broken imports
- tests/conftest.py: added FakeResponse, client fixture, tmp_token_dir fixture, and _CaptureHandler (stubs for integration tests) - tests/test_call_peer_errors.py: rewrote all tests to use existing client.py patterns (MagicMock session) instead of non-existent httpx fixtures. Removed mocker/http_mock/conftest fixtures that don't exist in this repo. 12 tests now cover: timeout, connection error, 4xx/5xx errors, empty body, JSON-RPC envelope format, auth headers, direct→proxy fallback path.

The function guards against escape via ``target.relative_to(dest_abs)``. This

rejects:

• Entries whose resolved path is outside ``dest`` (absolute paths, paths that

• Symlinks and hardlinks entirely (silently skipped, no file written).

These are unit tests with no external dependencies.

Paths that contain ``..`` but still resolve inside ``dest`` are ACCEPTED.
|

For example ``foo/../bar.txt`` resolves to ``dest/bar.txt`` which is inside

``dest``, so it is accepted.

2. **Absolute paths** — entries with a leading ``/``.

|
||||
- SHA256 manifest format stability
|
||||
These tests exercise the full round-trip: the SDK calls
|
||||
``POST /v1/plugins/verify-sha256`` with the plugin directory's content
|
||||
manifest, and the server responds. The ``mockserver`` fixture provides
|
||||
a pytest-scoped HTTP mock so individual tests don't need to patch
|
||||
``requests.Session`` manually.
|
||||
|
||||
Test cases:
|
||||
• valid SHA256 → server returns True → verify_plugin_sha256 returns True
|
||||
• tampered file → server returns False → raises SHA256MismatchError
|
||||
• server 5xx → raises PluginIntegrityError
|
||||
• server 404 → raises PluginIntegrityError
|
||||
• invalid request body → raises PluginIntegrityError (malformed payload)
|
||||
|
||||
GAP-02 (pending platform server implementation — fixture is ready).
