[github-actions]

Automated update of @github/copilot to version 1.0.78.

Changes

• Updated @github/copilot in nodejs/package.json and test/harness/package.json
• Re-ran all code generators (scripts/codegen)
• Formatted generated output
• Updated Java codegen dependency, POM property, and regenerated Java types

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/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/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 code generation update (@github/copilot → 1.0.78) and maintains full cross-SDK consistency across all six language implementations.

Changes applied consistently across all SDKs

Feature	Node.js	Python	Go	.NET	Java	Rust
HistoryClearContextRequest type	✅	✅	✅	✅	✅	✅
HistoryClearContextResult type	✅	✅	✅	✅	✅	✅
clearContext / ClearContext / clear_context RPC method	✅	✅ (type only)	✅	✅	✅	✅
session.context_cleared event type	✅	✅	✅	✅	✅	✅
InstalledPlugin.source_sha field	✅	✅	✅	✅	✅	✅
SessionInstalledPlugin.source_sha field	✅	✅	✅	✅	✅	✅
SessionModelChangeData.cause doc update (refusal_fallback)	✅	✅	✅	✅	✅	✅

API naming follows language conventions

• Node.js/TypeScript: clearContext (camelCase) ✅
• Python: types added; RPC method exposed through generated type registry ✅
• Go: ClearContext (PascalCase exported method) ✅
• .NET: ClearContextAsync (PascalCase + Async suffix) ✅
• Java: clearContext (camelCase) ✅
• Rust: clear_context (snake_case) ✅

No consistency issues found. All new types and methods are appropriately marked @experimental / [Experimental] across all SDKs.
