From 32b6c8ef2b615123946ba79b70a3454a3b99546c Mon Sep 17 00:00:00 2001 From: Andrew Miller Date: Fri, 12 Jun 2026 17:40:27 -0500 Subject: [PATCH 1/2] Add AsyncVisorClient and transport layer with full test coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements _transport.py (AsyncVisorTransport + SyncVisorTransport with typed error dispatch) and _client.py (AsyncVisorClient only — all 8 endpoints across Inventory, Dealers, and Usage resource groups). 32 new tests in test_client_async.py cover constructors, auth header propagation, every endpoint path and param serialization, error dispatch for all HTTP status codes, and context manager cleanup.

88a1f6af4694481efb42b3f5607e0c798bb0ff9b Mon Sep 17 00:00:00 2001 From: Andrew Miller Date: Fri, 12 Jun 2026 17:43:41 -0500 Subject: [PATCH 2/2] Fix AsyncVisorClient export and narrow transport error parsing Export AsyncVisorClient from the package root so `from visor import AsyncVisorClient` works. Narrow the broad `except Exception` in _handle_response to `except ValueError` for JSON decode failures only, then explicitly check the envelope shape before accessing .get("error") so malformed envelopes like {"error": "oops"} are caught and surfaced as unknown_error rather than silently collapsed.
