"""passthrough x Azure (Microsoft Foundry).

Drive the real `claude` CLI in foundry mode (CLAUDE_CODE_USE_FOUNDRY=1)
with ANTHROPIC_FOUNDRY_BASE_URL aimed at the proxy's `/azure`
passthrough route. The CLI POSTs `/v1/messages` with the model in the
JSON body -- unlike the bedrock/vertex modes there is no model segment
in the URL, so the proxy's router-alias resolution cannot engage and
the `/azure` route falls back to its env-configured target: the proxy
must set AZURE_API_BASE to the Foundry resource's Anthropic surface
(`https://<resource>.services.ai.azure.com/anthropic`) and
AZURE_API_KEY to the Foundry key (see
cron_vm/litellm-compat-matrix.env.example). The model ids are the
Foundry deployment names, which this matrix provisions to match the
Anthropic ids.

The (feature, provider) for this cell is inferred from the file path by
`tests/e2e/claude_code/conftest.py`:

    tests/e2e/claude_code/passthrough/test_azure.py
                       ^^^^^^^^^^^     ^^^^^
                       feature_id      provider

Wiring verified live at authoring time: through `{proxy}/azure` the
Foundry Anthropic surface accepted the `api-key` / `Authorization:
Bearer` headers the fallback sends (a bogus key 401s, the real key
proceeds to deployment lookup), so a red cell here means missing
AZURE_API_BASE/AZURE_API_KEY on the proxy, missing Foundry deployments
for the three tiers, or a genuine forwarding gap -- not an auth-scheme
mismatch.

Known-red at authoring time against a healthy Foundry resource: the
`/azure` fallback assembles only its own auth headers and drops the
rest of the client's headers, including the `anthropic-version` header
the CLI sends, and Foundry's Anthropic surface rejects the request
with 400 "anthropic-version: header is required" (the same request
sent directly to Foundry with that header succeeds). This cell stays
red until that forwarding gap is fixed, which is precisely the class
of bug the row exists to surface.
