Runtime 1.0.56 changed disconnect semantics so that ForceStop of the
last RPC owner now triggers session cleanup. The previous
warm-only test for `Should_Keep_Pending_External_Tool_Handleable_On_*_Resume_When_ContinuePendingWork_Is_False`
asserted SessionWasActive == true and that `handlePendingToolCall`
fed a result into the assistant reply -- assumptions that only hold for
warm resume. On cold resume the runtime intentionally auto-completes
orphan tool calls with a synthetic interrupt result, so the SDK call
correctly returns success=false.

Split that test into two scenarios across Node, Go, .NET, and Python:

- Warm (original client stays connected): SessionWasActive=true,
  handlePendingToolCall returns success=true, and the assistant echoes
  the supplied result.
- Cold (original client ForceStopped before resume): SessionWasActive=false,
  handlePendingToolCall returns success=false, and a follow-up turn
  confirms the resumed session is still healthy.

In warm mode the resumed client must not re-register the external tool
(it would clash with the original owner); in cold mode it re-registers
with a throwing handler to assert the runtime does not re-invoke the
handler on resume.

Runtime PR #9040 (commit b8e1220b45) made SDKServer.handleConnectionClosed
clean up session state when the last RPC owner disconnects. As a result,
the existing Should_Continue_Pending_{Permission,External_Tool}_Request_
After_Resume tests, which ForceStop the suspended client and then expect
the resumed client to successfully complete the pending request, no longer
pass: HandlePendingPermissionRequest/HandlePendingToolCall return
success=false after the cold cleanup runs.

A runtime-side fix is being tracked separately. Skip these two tests in
all four SDKs (.NET, Go, Node, Python) with a TODO referencing the
runtime contract change so they can be re-enabled once that work lands.

Also drop the GetFinalAssistantMessageAsync continuation assertions from
the .NET and Go warm theory and from the older OLD tests, matching the
Node and Python tests which never made that assertion. The
ContinuePendingWork=false warm path provides no guarantee that the
suspended client's agentic loop will propagate a final assistant.message
to the resumed client, and waiting for one was flaking on Linux .NET CI.

The previous wording ('Pending runtime fix') implied a runtime change was being tracked separately. That isn't accurate: runtime 1.0.56 (copilot-agent-runtime PR #9040) intentionally cleans up the session when the last RPC client disconnects, and there is no in-flight fix planned.

The OLD tests model same-process ForceStop+resume and rely on the old behavior where the session stayed alive in the runtime process. They need to be redesigned to either keep an owner connected (warm resume) or to model true process-restart resume from persisted session state.

No code change beyond the skip-reason text; tests remain skipped while the redesign is figured out.

Cross-SDK Consistency Review

This PR updates the @github/copilot schema to 1.0.56 and re-runs code generators. The generated documentation changes are applied consistently across dotnet, go, nodejs, python, and rust — good job! 🎉

⚠️ Java SDK not regenerated

The Java SDK's generated files (java/src/generated/java/) were not updated and still contain outdated documentation comments:

File Stale comment
ModelBillingTokenPrices.java /** Maximum context window tokens for the default tier */
ModelBillingTokenPricesLongContext.java /** Maximum context window tokens for the long context tier */
SessionMetadataContextInfoResult.java /** Total context limit for /context display. promptTokenLimit + min(32k or 64k, outputTokenLimit) depending on model. */

Other SDKs now read:

  • "Prompt token budget (max_prompt_tokens) for the default/long context tier. The total context window is this value plus the model's max_output_tokens."
  • "Total context limit for /context display: promptTokenLimit + outputTokenLimit (the model's full max_output_tokens reserved on top of the prompt budget)."

To regenerate Java, run: cd java && mvn generate-sources -Pcodegen

i️ Java pending_work_resume E2E tests

The PR updates pending_work_resume E2E tests in go, dotnet, nodejs, and python. Java has no equivalent PendingWorkResume E2E tests yet — this is a pre-existing gap (not introduced by this PR), but worth noting for future parity work.
