The check spins up a hypercorn TLS peer and drives the SDK's own httpx
handlers at it, so it needs litellm importable, hypercorn installed and a
loopback socket. It lived under tests/e2e, whose Buildkite runner image
installs neither litellm nor hypercorn by design (the suite drives a
remote proxy over HTTP), so every scheduled e2e build since #230 failed
to import the module and pytest reported it as a collection error. The
unit tree bans sockets, so it does not belong there either
tests/integration is the CircleCI tier built for real TCP against local
protocol peers. This adds an sdk shard to it for cases that exercise the
SDK's clients with no gateway in the path, registers the two HTTP/2
nodes in the contracts manifest, and adds the shard to the CircleCI
matrix. The test now flips the feature through LITELLM_HTTP2 (the user
surface) instead of patching module attributes, and asserts the version
the peer observed on the wire next to the one the client reports
Adds integration contracts for MCP lifecycle, protocol errors and OAuth
configuration, A2A wire versions, the OpenAI consumer path, persisted
toolsets, callback delivery, guardrail effects, configured prices, the
filtered spend ledger, and a CircleCI-owned browser flow for project
detachment, with the ASGI, browser-state, client and MCP helpers they use.
Consolidates the eleven commits previously stacked on
litellm_integration_providers onto its rebased tip
Adds owned local TCP peers, a Redis process helper and SigV4 helpers to
tests/integration, and integration contracts for Anthropic and Bedrock wire
shapes, Bedrock role configuration, S3 wire, observed routing, Redis
recovery and stream contracts. Consolidates the four commits previously
stacked on litellm_integration_accounting onto its main-merged tip
