Bug: The module-level subscribed flag in langGraphChannelIntegration is not reset between tests, causing subsequent tests in the same file to skip channel subscription and fail.
_{Severity: MEDIUM}

Suggested Fix

The subscribed flag should be reset to allow re-initialization in test environments. This can be achieved by exporting a reset function from the integration module that sets subscribed = false and calling this function within the test's resetGlobals() or a similar teardown/setup utility. This would ensure each test runs in a clean state without interference from previous tests in the same file.

Review the code at the location below. A potential bug has been identified by an AI
agent. Verify if this is a real issue. If it is, propose a fix; if not, explain why it's
not valid.

Location: dev-packages/deno-integration-tests/suites/orchestrion-langgraph/test.ts#L40

Potential issue: The `langGraphChannelIntegration` uses a module-level `subscribed` flag
to ensure its setup logic runs only once. In test environments where `init()` is called
multiple times in the same process (e.g., multiple `Deno.test` calls in a single file),
this flag is not reset. The `resetGlobals()` function only clears Sentry scope state,
not module-level variables. As a result, after the first test sets `subscribed` to
`true`, subsequent tests will skip the channel subscription logic within `setupOnce()`.
This causes test failures because the second test's channel events are incorrectly
processed by handlers registered during the first test, which are bound to the first
test's transaction sink.
