fix(client): request expanded fields in get_ticket

[seanGSISG]

Problem

zammad_get_ticket reports Unknown for State, Priority, Group, Owner and Customer on every ticket:

# Ticket #190017 - Office Location Adjustment for New Hire
**ID**: 17
**State**: Unknown
**Priority**: Unknown
**Group**: Unknown
**Owner**: Unknown
**Customer**: Unknown

Cause

ZammadClient.get_ticket() fetches through zammad_py's ticket.find(), which issues a plain GET with no query parameters:

def find(self, id: int) -> Any:
    response = self._connection.session.get(self.url + "/%s" % id)
    return self._raise_or_return_json(response)

Without expand, the single-ticket endpoint returns group_id / state_id / priority_id / owner_id / customer_id and omits the name fields. Ticket.group, .state, .priority, .owner and .customer therefore deserialize to None, and _brief_field renders each as Unknown.

Confirmed against a live instance — find() returns group=None, state=None, priority=None with only group_id=2, state_id=4, priority_id=2 present.

The Ticket model already anticipates the expanded form:

# Expanded fields - can be either objects or strings when expand=true
group: GroupBrief | str | None = None
state: StateBrief | str | None = None
priority: PriorityBrief | str | None = None

So only the request was missing. search_tickets() and the other list methods already pass expand="true", which is why search results render correctly and single-ticket lookups do not.

Fix

ticket.find() accepts no query parameters, so the request goes through the library session directly — the same approach list_tags() already uses for an endpoint zammad_py doesn't expose.

Verification

Same ticket, same instance, after the change:

**State**: closed
**Priority**: 2 normal
**Group**: GSI Tech Team
**Owner**: -
**Customer**: user@example.com

Tests

The two existing get_ticket tests mocked ticket.find and are updated to mock the session response. Four regression tests added covering the expand parameter, the request URL, expanded names surviving deserialization, and HTTP errors propagating.

ruff check, ruff format --check, mypy and the full suite (226 tests) all pass.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Walkthrough

get_ticket now uses a direct expanded HTTP request, validates HTTP status, and parses JSON ticket data. Tests cover request parameters, endpoint construction, expanded reference names, pagination fixtures, and error propagation.

Changes

Ticket retrieval

Layer / File(s)	Summary
Direct expanded ticket request mcp_zammad/client.py	get_ticket calls the authenticated session for /tickets/<id> with expanded fields, raises HTTP errors, and returns parsed JSON data.
Ticket retrieval validation tests/test_client_methods.py	Tests mock direct HTTP responses and verify expanded requests, endpoint URLs, expanded reference names, pagination fixtures, and error propagation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 79d0a

The change fixes missing ticket fields, but the new direct request can wait indefinitely if the service or network hangs. The PR is mergeable with explicit owner follow-up to add a bounded request timeout.

Both addressed in 54d04ea.

Bounded client-level timeout. requests defaults to waiting indefinitely, so the session.get calls had no ceiling — a stalled connection would hang the tool call outright. Added a client-level timeout, settable per instance or via ZAMMAD_REQUEST_TIMEOUT, defaulting to 30s.

Applied to both direct session calls, not just get_ticket — list_tags() bypasses zammad_py the same way and had the same gap, so the two paths now stay consistent.

The value is genuinely bounded rather than free-form: positive and no greater than 600s. Unparseable or out-of-range settings log a warning and fall back to the default, so a misconfiguration can't quietly restore the unbounded wait, and no configuration path can produce None.

Verified against a live instance rather than only mocks — the default applies to real requests, and a 1ms override raises requests.Timeout, confirming the value reaches the socket and not just the call signature.

Seven tests cover it: the default, a constructor override, list_tags using the same value, env configuration, invalid and out-of-range values falling back, the upper bound being accepted, and the timeout never being None. test_list_tags is updated for the new call signature.

Owner coverage. test_expanded_names_survive now includes an expanded owner in the mocked payload and asserts it survives alongside group, state, priority and customer — worth having explicitly, since owner was one of the five fields rendering as Unknown in the original report.

ruff check, ruff format --check, mypy and the full suite (237 tests) all pass.

Confirming this reproduces exactly as described on our own instance (pulling :latest) — get_ticket reports Unknown for State/Priority/Group/Owner/Customer on every ticket, while search_tickets correctly resolves the same fields for the same tickets, matching the expand param diagnosis here. Looks like a solid root-cause + fix already written up — just flagging that we're hitting it in production too and would appreciate this landing on main/:latest when convenient.
