* test: drop the cwd-relative sys.path.insert calls from the test suite
TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.
Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.
Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.
* test: drop the duplicate imports the sys.path sweep exposed to F811
* test(pre-call-utils): restore the os import the new bedrock tests need
The Jina key fallback chain read JINA_AI_API_KEY three times in a row
before falling through to JINA_AI_TOKEN, so two of the four slots were
dead. Jina's own documentation publishes JINA_API_KEY, and litellm's
rerank validate_environment already tells users to set that name, but
nothing ever read it: a user who set only JINA_API_KEY got no key
resolved and Jina answered AUTH_MISSING_API_KEY.
Replace one of the repeats with JINA_API_KEY and drop the other.
JINA_AI_API_KEY stays first so no install that resolves a key today
changes which key it picks.
