Java Handwritten Code Adaptation Plan

If java-sdk-tests CI fails on this PR, follow these steps:

1. Identify failures: Run mvn clean, mvn verify from java/ locally or check the java-sdk-tests workflow run logs.
2. Categorize errors:
   • Constructor signature changes (new fields added to generated records)
   • Enum value additions/renames in generated types
   • New event types requiring handler registration
   • Removed or renamed generated types
3. Fix handwritten source (java/sdk/src/main/java/com/github/copilot/sdk/):
   • Update call sites passing positional constructor args to include new fields (typically null for optional new fields).
   • Update switch/if-else over enum values to handle new cases.
   • Register handlers for new event types in CopilotSession.java if applicable.
4. Fix handwritten tests (java/sdk/src/test/java/com/github/copilot/sdk/):
   • Same constructor/enum fixes as above.
   • Add new test methods for new functionality if the change adds user-facing API surface.
5. Validate: cd java && mvn clean test-compile jar:jar && mvn verify -Dskip.test.harness=true
6. Format: cd java && mvn spotless:apply
7. Push fixes to this PR branch.

To automate this, trigger the java-adapt-handwritten-code-to-accept-upgrade-changes agentic workflow instead.

Cross-SDK Consistency Review ✅

This PR is an automated schema-driven codegen update (@github/copilot → 1.0.81-9) that regenerates types across all six SDK implementations:

SDK	Files updated
Node.js/TypeScript	nodejs/src/generated/rpc.ts, session-events.ts
Python	python/copilot/generated/rpc.py, session_events.py
Go	go/rpc/zrpc.go, zsession_encoding.go, zsession_events.go, types.go, zsession_events.go
.NET	dotnet/src/Generated/Rpc.cs, SessionEvents.cs
Java	Multiple files under java/sdk/src/generated/
Rust	rust/src/generated/api_types.rs, rpc.rs, session_events.rs

Key changes introduced consistently across all SDKs include:

• ConnectClientInfo — new type for host identity on the server.connect handshake (telemetry attribution)
• ModelMessage / ModelWarningText — new types for service-published model notices
• ModelCallFinishedEvent / ModelCallFinishedOutcome — new lifecycle event for model dispatches
• output_ttft field on AssistantUsageData
• New MODEL_CALL_FINISHED session event type

All of these are code-generated from the shared schema and appear consistently across all six languages. No cross-SDK consistency issues found.
