Change-detectors, tautologies, source-reading tests, redundant duplicates, mock-echo tests and dead/unrunnable tests. Per-test rationale in the lane ledger (category + reason for every removal).

"""Tests for cross-loop client cache isolation fix (#2681).
|
|
|
|
Verifies that _get_cached_client() returns different AsyncOpenAI clients
|
|
when called from different event loops, preventing the httpx deadlock
|
|
that occurs when a cached async client bound to loop A is reused on loop B.
|
|
|
|
This test file is self-contained and does not import the full tool chain,
|
|
so it can run without optional dependencies like firecrawl.
