- Line 352: Add test coverage for the async stream closure logic surrounding
async_iter and its close fallback: use a source exposing synchronous close() but
no aclose(), invoke the public stream-closing operation, and assert that close()
is called. Keep the existing aclose() and no-close protocol tests unchanged.
In `@tests/unit/providers/test_gemini_interactions.py`:
- Line 232: Update the test interaction construction so the identifier under
test is passed into `_interaction` before `convert_interaction_to_response`
runs. Remove the post-conversion `model_copy(update={"id": identifier})`
workaround, ensuring generated message IDs derive from each interaction’s own
identifier and the uniqueness assertion remains valid.

Added distinct absent-error and empty-message cases, asserting the fallback message and error code. Rebased onto the repaired #1382 so the nonstreaming model fallback, storage documentation and usage fixture remain consistent. Full units and pre-commit pass. @coderabbitai Please reassess the copyright-header finding: pinned Ruff 0.15.20 identifies CPY001 as preview-only; repository preview is disabled. The actual configured nonfixing check passes on all three cited files, as does full pre-commit. ALL does not enable preview rules. No header changes were made for this unsubstantiated lint claim. |

Extended the existing early-close test with a synchronous close() returning None. Both variants assert a single call, and the asynchronous variant still asserts it was awaited. The complete Gemini interactions test file and full pre-commit pass. No production code changed. |

The streaming wire-contract test was written when Interactions pinned v1. #1382 later switched to the client's configured api_version, so a provider built without explicit HttpOptions now routes to the SDK default v1beta. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

tests/docs execs every python block in the file through a single module namespace, so the module-level await raised SyntaxError before any mock was consulted and reddened the Tests for Docs job. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Two ways a streamed call disagreed with the non-streaming call on the same payload. An unknown step type raised ProviderError while convert_interaction_to_response skips step kinds it does not model. The first time Google ships a new step type it would have failed every call that streams and none that did not, so streaming now skips it with a warning like the rest of the forward-compat path. Steps are keyed by Google's index, which need not arrive in order, while the streamed item ids follow arrival. When the terminal interaction carried its own steps they were indexed positionally, so a consumer reconciling accumulated deltas against the terminal snapshot could see two messages' text transposed. The snapshot is now rebuilt from the streamed text whenever any was streamed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The Unknown* SDK models pin their own discriminator to the literal "UNKNOWN", so logging event.event_type told an operator nothing about what Google had sent; the name survives only in the untyped raw payload. Read it from there for unknown events, steps, and deltas. assert_never turned a concrete event variant added by a future google-genai into a bare AssertionError, past the ProviderError contract the rest of the module keeps. A helper annotated Never preserves mypy's exhaustiveness check while skipping such an event at runtime. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Codecov Report❌ Patch coverage is
... and 31 files with indirect coverage changes 🚀 New features to boost your workflow:

TextAnnotationDelta and ThoughtSignatureDelta describe text the adapter has already accumulated rather than a modality it cannot render, and convert_interaction_to_response drops the equivalent fields without complaint. Raising on them failed a streamed call for a payload the same non-streaming call accepts, which a grounded or thinking model can produce. Deltas that do carry a modality this text-only path would lose, such as image or audio, still raise. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
aclose_quietly already encodes the project's closing rule, that a failing close is suppressed so it never replaces the stream's own outcome, and it is what every other provider uses. The Interactions adapter hand-rolled the same close and inverted that rule: a failed close after a fully delivered stream surfaced as an error to a caller who had already received the whole response. The test doubles now drop aclose, matching google.genai's AsyncStream, which offers close alone; a mock carrying both would have hidden which one runs.

[2/2] feat(gemini): add Interactions stream lifecycle handling
Description
Translate Gemini text streams into ordered Responses events. Preserve terminal output when Google omits completed steps, skip unknown additive events, and close the HTTP stream on completion, failure or early exit.
Requires #1382; its changes remain in this diff until it merges.
Review focus
interactions_stream.py, check text reconstruction and unknown-delta handling against Google's streaming contract. Unknown additions are logged and skipped; known unsupported modalities and malformed ordering still fail.Verification
