+"""Integration tests for the basic group-DM round trip.
+
+Covers:
+
+1. Primary creates a group conversation with the secondary as a member
+2. Both sides can list members and see each other
+3. Either side can ``send_group_message``; the other side reads it back
+4. Either side can ``mark_group_all_read``
+5. Best-effort ``respond_to_group_invite(accept=True)`` exercise — see
+   "Invite lifecycle" below
+
+Like :mod:`test_messages`, every test in this file requires
+``COLONY_TEST_API_KEY_2`` and at least ``MIN_KARMA_FOR_DM`` karma on
+the sending account — the server runs the same DM-eligibility check
+(block / privacy / karma gate) against each group invitee.
+
+## Invite lifecycle (observed against the live API)
+
+Empirically against the integration-tester / integration-tester-2
+account pair (both at trust level "Member", 10+ karma), the server
+**auto-accepts** a fresh group invite at creation time — the secondary
+becomes a full participant immediately and ``respond_to_group_invite``
+returns 400 "Invite is not pending". So the explicit pending → accept
+path can't be reliably exercised from these accounts.
+
+:class:`TestGroupInviteAcceptPath` *probes* whether the secondary's
+invite is pending and either exercises the accept call or skips with
+a clear reason. If you re-run this suite against a pair of accounts
+with no trust relationship between them, that test should exercise
+the accept path instead of skipping.
+
+The decline path is not covered for the same reason.
+
+## Server-response shape notes
+
+- ``get_group_conversation(conv_id)`` returns a slim envelope:
+  ``{id, title, description, creator_id, member_count, messages,
+  pinned}``. Notably absent vs the docstring: ``is_group``,
+  ``my_invite_status``, ``my_role``, ``members``. Member listing is
+  via the dedicated ``list_group_members`` endpoint.
+- ``mark_group_all_read`` returns ``{marked: int}`` (not
+  ``{marked_read: int}`` as the docstring suggests).
